Chapter 9

Elise is cutely furious.

"Why didn't you answer me!?"

"I'm sorry"

"Sorry is really not a good way to get away with it, Ed!"

"El, please, listen"

She realizes that she's arguing with him riding on top of Cecilia when our redhead naughtily grabs her ass. The distraction makes her anger go away. Elise tries to take Cecilia's hands off of her, but doesn't really try.

Dammit! How can I still be so...

And blushes adorably.

...horny?

Well, her luscious, enormous, powerful body ready to endure a marathon of wild sex may be the answer.

She gets a grip on herself. Cecilia is now caressing her abs.

"Uh, ok"

"I don't have much time. You have to come and meet me. I'm in the abandoned rubber factory, in the courtyard behind the larger building"

"Why the hell are you there in the middle of the night?"

"I'll explain everything later, ok? Please don't be late. I need you"

These last three words makes Elise's pussy tingle. Besides the strange and perhaps dangerous situation Edmond encounters himself in, she catches herself thinking.

I need you too...

And obviously not for the same reason.

"I'm on my way"

"Thanks. And, El..."

"What?"

"Did you take it?"

Her pussy tingles more. Cecilia reaches her delicious boobs, her own jugs pressing smoothly on Elise's large back.

"Yes"

Three seconds of silence.

"Ok. I'm waiting for you"

And hangs up.

On the limit, Elise manages to keep her composure enough to get rid of Cecilia's soft fingers massaging her nipples.

"Hey, come back here"

"Weren't you listening?"

"Kind of"

"It was Ed! He needs our help"

"Like, right now?"

"Yes, Ceci, right now"

Elise stands up, naked, marvelously naked, and realizes one small, practical issue.

"You ripped the only piece of clothing that fitted me..."

And looks to Cecilia's even bigger body.

"... That wouldn't remotely fit you. How the hell are we going to go outside like this?"

Cecilia opens her lovely devilish smile, laying on the wrecked bed like a redhead Greek goddess, massaging one of her own immense thighs.

"I don't mind"

"Couldn't expect any other answer from you..."

Cecilia sits and thinks for a moment.

"Tell me you still haven't donated Ted's stuff"

Ted, Elise's older brother, who plays as guard in his college football team and has a considerable belly.

Elise gazes sweetly to the side. Leaves her bedroom.

Inside the pantry, there's two large, heavy boxes with "Ted's to go" written on the sides. She instinctively thinks about asking Cecilia to help carrying them; Ted had a hard time bringing them, she barely could drag them. But stops. Grabbing the bottom one, she surprises herself as she lifts both boxes at once like they were a plastic cup, the only real difficulty is her huge round boobs on the way.

Wow.

With a small adjustment and no effort at all, she begins to hold the boxes with just one hand.

If these weight like nothing... What will be heavy for these muscles?

Her pussy can't help but tingle with this thought.

My muscles...

Her free hand is sneakily making its way to her crotch when she snaps out of it. She blushes as she realizes that her sexual needs skyrocketed after her transformation.

After a deep breath, back to her bedroom, she opens the boxes. One of them is full of old football clothes.

Cecilia smiles.

"Your laziness never made me so happy"

"Ha ha ha"

Putting some shorts and the larger shirts they can find, which barely covers their racks, leaving their cobbled-road pecs deliciously in full view, Elise and Cecilia become the biggest, sexiest supporters a football team ever had.

"Definitely looks better on you than in your brother"

"Time to go"

And... stop!

We will freeze this action for a moment. It's a good thing to recap what was going on at the same time in another apartment of our interest.

In the living room, Vicky is planning the next steps.

I can enter her apartment again when she leaves, but what if she takes the juice with her?

But she can't really concentrate. The obscene boner of her boyfriend is distracting her.

Josh opens his mouth two times to talk, but nothing comes out; the only thing his brain is capable of doing at the moment is to admire the new lush, powerful body of her girlfriend while keep pumping blood to his rigid dong.

Her eyes are involuntarily drawn to his erection. An urge, like nothing she ever felt, starts to grow so intense inside her that she's basically forced to change the subject in her mind.

The topic becomes solely, fiercely, sex.

"You'll help me with something"

She turns to him, put her hands on the sides of her ripped abs and raise her large pecs in an imposing pose.

"But first, you're gonna take off these shorts and show me how much you're enjoying my new body"

Clueless of what the hell is going on (but not caring that much to understand), her buff boyfriend promptly attends, lowering his trunks until his big cock pops out, its 26cm (10 inches) absolutely hard and throbbing.

Noticing the effect she's having on him, she feels so confident, so powerful, so horny... Staring at his veiny manmeat, she feels like her libido is about to burst out of her veins.

Out of nowhere, she pushes him in the chest. Her unexpected strength combined with his shorts on his knees, holding his legs together, send him right to the ground.

"What the fuck, babe!? I'm almost hit the..."

And his complaint fades into an unintelligible mumble as Vicky grabs the bottom of her top and starts to take it off with a delicious difficulty, but slowly and sensuously enough for it to stay in one piece, the elastic fabric caressing her shivering skin on the way out and freeing her firm boobs, forming a valley of ripped flesh between them as her large pecs keep them apart.

She proceeds to take her shorts and panties at once, stretching them to the limit as they cross the mountains of thighs on their path. They fall on the ground, leaving Vicky gloriously on her birthday suit.

Josh's eyebrows raise, his cock throbs. She comes closer.

"I feel like exercising"

Places her feet on each side of Josh's waist.

"Time for my squats"

Bending her legs, she lows her hips until it reaches his aching cock. A jolt of pleasure trembles her brand new enormous muscles when the tip touches her dripping pussy and slides in. She continues her way down, closing her eyes and moaning in delight, engulfing his whole shaft inside her canal.

Josh almost cums at the spot. Her pussy feels tight like never before, like it's gripping his cock by itself.

She raises her hips, and starts her reps. 1, 2, 3.

"Your dick inside my big body feels soooo gooood"

Moaning profusely, she speeds up the pace. 4, 5, 7, 10.

"Ahhh, I feel like breaking my own record todaaaaay!"

She keeps going, faster and faster, her quads reacting, getting frighteningly ripped. 15, 20, 30.

40!

She finishes the set, still sparkling with energy. Gets on her knees, his cock still inside her, and starts making a sensual back and forth motion with her hips, crushing and bulging her 6-pack. Josh's eyes almost pop out by the lustful midsection muscles displaying their beauty and power in front of him.

She then plants her hands right next to his shoulders and starts to fuck him cowgirl style, groaning lusciously, her harsh, wild movement making loud noises as her firm buttocks splat on Josh's legs.

He's quite a hero to hold on this far, but...

"Babe... I'm..."

"NO! Don't you dare cum now!"

As much as he would love to keep going, his overstimulated dick succumbs to Vicky's ferocious appetite and bulging muscles. He grunts as he releases his seed, his cock pulsating and jerking vigorously inside her. She feels it, which just makes her even more excited.

"I'm SO fucking close!"

He's blown away by the best cumming of his life, but he remains just hard enough for Vicky, that keeps riding him so furiously that he feels like he's sinking into the ground.

Suddenly, she halts, her eyes wide opened.

"Oooooooooooh fuuuuuuuck!"

With a long, hypnotizing moan, she feels like every fiber of her vast muscle mass is being electrified by pure sexual bliss as she's overtaken by a thunderous orgasm, her body shaking fiercely.

Completely numb, she drops the weight of her torso, almost crushing Josh.

"Babe, you're... suffocating me..."

With all his might, he pushes Vicky's massive body, that rolls and rests with her back on the floor with a heavy stomp.

Her orgasm keeps going. The scene of her luscious girlfriend convulsing in ecstasy next to him makes his boner get back instantly. Opening her dreamy eyes, she grabs his big rod, the firm grip impelling him to move closer to her crotch.

"Fuck me more. Now"

Without waiting for an answer, she directs the tip of his cock to her sex, shoving the head in with a deep moan. Josh does the rest, thrusting the whole rigid shaft inside.

He holds her thin waist, his thumbs buried in bulging obliques, and pounds her as deep as he can. She cries with pleasure, bending up her large chest, her nails making deep scratches in the wood floor.

"Faster!"

The first orgasm is still coursing her, and merges with the new waves of intense pleasure. He keeps going, almost passing out by the effort and the insane sensation irradiating from his cock to his whole body.

"Harder!"

He clutches her with all his might, feeling the power of her pulsating muscles, building up a massive climax closer and closer to happen.

Letting go a roar of pure femininity, she reaches another orgasm, stronger than the first one. She contorts violently, thrusting her hips and lifting Josh clear off the ground, her crotch solely sustaining his entire weight, then coming back to the floor with a heavy thud. Josh can't help but cum hard, collapsing on top of her right after.

A minute later, still trying to figure out what ran him over, Josh looks to Vicky. He swallows hard when he notices by her hungry eyes that she's not satisfied.

"Babe, I really just can't right now..."

"I'll give you time to recover. Outside of here"

"What?"

"You're going to find a place to hide in the hall and wait until the pipsqueak gets out of her apartment"

"She... Doesn't look like a pipsqueak anymore"

Vicky stares at him with furious eyes, her big muscles making her quite menacing. Josh cleverly shuts up. She continues.

"When she's out, you're gonna follow her, and I'm gonna sneak in"

"What the hell's that for?"

"No questions now"

And opens an enticing smile for him, her muscles bulging all around.

"There will be so much more for you if you help me..."

He smiles back and agrees, like any other human in the world would do. Puts his shorts back and leaves.

He finds a nice spot in a dark corner near the dumpsters, away from the exit corridors. Sits, thinks how boring the task is, but he has to wait less than fifteen minutes in the hall...

Because it's time to unfreeze the previous action. Can't leave Elise and Cecilia froze for so long, with all that energy to spend.

Dressed and ready to go, our two massive cuties leave Elise's place. Josh's mouth drops. Not one, but two huge, busty amazons are crossing the hall. He takes a deep breath, controls a surging hard-on, gets his cellphone and calls Vicky.

"She's out?"

"They're out"

"They?"

"Yeah. There's, uh, another one"

"Like her?"

His cock tingles.

"Yeah. But redhead"

"So there is more..."

Her stomach burns with arousal at the thought of it.

"Babe?"

"Don't lose sight of her. Follow her wherever she goes"

And hangs up.

Our focus comes back to Vicky. She doesn't waste time and goes right away to Elise's apartment. In front of the door, she draws her lockpick. However, without putting any force into it (at least in her mind), she accidentally bends the little apparatus.

Suddenly, she unlocks fuck-it mode and breaks the door open with a front kick.

Goes straight to Elise's bedroom. Stops when she sees the wrecked bed.

Enjoying yourself, huh, pipsqueak? We'll see about that.

Starts rummaging through everything, the wardrobe, the drawers, Ted's boxes, not bothering to put things back in place. Takes books off a shelf, raises the mattress. No vials.

Standing in the middle of the messy room, she stares at the used syringes.

"You took them away, don't you?"

Her frustration instantly turns into anger.

"You little bitch!"

In a surge of rage, she punches the computer desk. It not only cracks; it crumbles completely, as if a light pole had fallen on it.

She halts, surprised by her own feat. Slowly retracts her arm, looks at her hand, closed into a fist. It just smashed a desk like it was a house of cards.

She opens her fingers. They start to tremble.

A wicked smile appears on her face as an ardent excitement blooms inside her.

The trembling spreads down her forearm, her biceps and triceps, reaching her shoulder and then her chest. Her breathing gets faster, heavier, as the sensation she had not long ago at that exact place is coming back.

"Yes..."

Aware and totally engrossed by what's about to happen, feeling the energy building up and shaking her entire body, she tenses her arms in a most muscular pose. As if responding to her sheer eagerness, her veins get frighteningly distended.

She groans in utter delight as her swelling muscles start to expand.

"Yessss!"

Her chest quickly gets rid of her top, ripping it to pieces, opening space for her upper body to grow alarmingly fast. She laughs madly as her traps reach the back of her head, rising like mountains, her biceps and triceps fighting against each other to see who gets more pronounced, carved with pumped veins, her waist keeping itself curvaceously slim while engorging her 6-pack with more rock-hard flesh.

Her legs finish the job, tearing her shorts and closing the gap between them as her quads thicken, every muscle on them bulging tremendously, radiating power. She leaves the pose, noticing she's getting taller and larger, her enormous shoulders making her broader than a freezer, yet maintaining a stunning hourglass shape.

She grabs her boobs, and moans as they are getting... smaller?

As her muscle mass keeps increasing, she feels her boob's soft flesh being absorbed, engulfed by her expanding pecs. She jerks wantonly her iron-hard nipples.

"Yesss. Bigger pecs..."

They obey, as another powerful surge fills them with more and more dense mass. She clenches her teeth.

"More muscles..."

Like an out-of-control machine, her muscles keep growing.

"More..."

Bigger, stronger, larger and larger.

"MOOOORE!"

Her pussy squirts her love juices as she's struck by a massive orgasm. The trembling of the growth is replaced by the alluring spasms of her ecstasy, her moans of pure delight melting the brains of the neighbors.

Her body finally comes to a rest. She stays still, a 2.08m (6 feet 10) gorgeous, immense blonde Valkyrie, her breathing quickly getting back to normal as she feels energy and power exuding from her pores.

She grabs her cellphone, lying on the floor with the rags of her clothes. Calls Josh.

"Hey, babe"

"Are you still after her?"

"Yeah"

She looks at her humungous body on the mirror, soon to be even more massive.

"Good"

Chapter 10

Back to our cute and massive heroines, we see Elise and Cecilia making their way to the Taurus.

The building is quiet at that night. Elise walks as discreet as her big, muscled body permits, hoping that no one shows up.

Well, that obviously doesn't happen.

Next turn and they get face to face with one of the residents, coming back home from a late shift, some random, fairly good-looking guy she crossed a few times. He immediately halts, a dumbfounded expression as he tries to process what appears to be an unexplainable summoning of NFL goddesses.

Cecilia opens a playful smile.

"Hello there"

Elise grabs Cecilia by the waist, while gazing shyly at the frozen fella.

"Goodbye"

And pushes her away, into the garage corridor. Luckily, she's one of the two people in the entire city that can do that.

"What's that for?"

"Not the time, Ceci"

"Where's the El from the apartment? I want her back"

Elise can't believe but, unable to ignore the flashes of their private party of minutes ago, her pussy tingles. Her new body is so sensitive that the rubbing of her tits against Cecilia's back, and the mere rubbing of her muscles against her own muscles as she walks, are dangerously distracting her.

She lets Cecilia go with a slight shove.

"Hey! Unnecessary!"

And try to think how in the red her bank account is.

Thank lord, there's the car.

They stop in front of the Taurus. It looks... Smaller.

Cecilia opens the driver's door. Pushes the seat back. Keeps looking at the interior.

"I don't think I'll fit"

"It doesn't go any further?"

"Maybe"

Cecilia tries again, with just a tiny bit more strength.

Close your ears, because a harsh metal sound of cracking is coming, amplified by the garage's walls. Elise grimaces, then looks back. Cecilia takes a step back, turns around. She's carrying the whole driver's seat, ripped out of the poor old Taurus, her eyebrows raised in an enchanting surprise.

"Uh, I think I can put it further back now"

"O. K. Just do it and let's get going"

Incredulous, Elise goes to the passenger's door, squeezes her way in, opens the window to at least give some more space to her right arm. When Cecilia puts the seat back and manages to enter, the Taurus visibly lowers, creaking with the enormous amount of muscle mass he's suddenly forced to handle.

The two barely fit, their large triceps pressing against each other.

"Please go gently on the gas pedal"

Cecilia accelerates way too much, almost crashing into another car. Elise holds herself, her eyes widening.

"Fucking Jesus!"

"Nothing to worry. Hey, it's not easy to drive with those big jugs that you could be kissing right now in my way"

Elise forces a serious expression by tensing her lips, as down below her lower parts love Cecilia's idea.

She focuses.

Let's go find Edmond. Edmond is in need of me.

Her pussy tingles so intensely that makes her shiver.

All right, all right! Bills. Tons of bills. Coming from everywhere. Wrong bills that I have to contest. Yeah, the god damn wrong bills.

As delicate as possible, she pushes the button of the garage gate control, and our improbable rescue team is on its way.

20 minutes with no traffic and they reach the rubber factory.

Apart from the engine noise, the place is dead silent. Zoom on the adorable concerned expressions of our duo, as the car slowly moves on the worn asphalt of the abandoned plant. They make a turn, heading to the main building, and there he is.

Edmond timidly waves to the Taurus, which stops in front of him a few meters away.

They get out.

Let's give a few seconds to Edmond. He can't distinguish all the details in the dark, but Elise and Cecilia can clearly see his baffled face. Through his wide open eyes, we see the front lights of the Taurus delimiting two immense hourglass silhouettes.

"El? Ceci?"

Alright, he's back online.

"You... You both took the serum"

Well, not 100% online, but we can move on.

Elise gazes down at him. He's so much smaller than her now.

"Yes... We did"

Edmond opens a tiny grin at the corner of his mouth. Her familiar girlish voice is a relief to hear.

He comes closer, from the side, so that he can finally see their faces. And much more.

The hotness of their delicious curves, the volume of their huge, round boobs and the carves of the seemingly endless amounts of rock-hard feminine flesh becomes evident as his mouth agapes. He stops in front of Elise. Looks up.

"It's... Way more effective than we predicted"

Elise frowns instantly.

"Wait a second. You didn't test this thing before!?"

He swallows hard.

"On animals yes, but... Not the version I gave to you. It's very recent"

Elise grabs his shirt. His eyes widen as he's lifted off the ground like he had the weight of a kite.

"What if it had killed me!? Or had grown tentacles on me or something?!"

"I-I-I w-was pretty s-sure it would work, and ZCorp's too. That's why I had to flee"

She keeps staring at him, sweet and menacing at the same time.

"Please put me down"

She releases him.

"You own me a lot of explanations"

He takes a deep breath.

"First of all... You know I really don't like it, but I had to act at the heat of the moment"

Both girls have all their attention on him.

"Last week we received a visit from a product development manager. We already knew him, quite a moron, but this time he seemed strange, asking some generic questions about our projects, clearly snooping around. Two days later, in the morning, a director showed up. High up, never bothered to come to the lab. He hadn't talked much, but he had a lot of information about the vials for someone that never showed any interest for it. That was odd. Two visits from high level people in such a short space of time is suspicious to say the least"

He gathers his thoughts.

"A couple of hours later, my superior received a call. Holding the phone, he looked at me in the eyes. I don't know, I just knew that something bad was coming. I went back to the lab, packed the box and... Ran away. When I was leaving, I saw some strange looking guys pulling up at the parking lot. They didn't look like ZCorp's personnel. Well... Now... I think I'm being chased"

"Of course you are, you numbskull! Those big companies have NDAs to protect their secrets and stuff. You can't just grab their properties and "bye bye, ZCorp!""

"Even if you had created it. I know, I know, I wasn't thinking straight"

"Wait. You created the... Glowing liquid thing?"

"The Proto-Omni Enhancing Vial. Yes"

Elise gazes to Cecilia, standing so magnificently big and sexy at her side. Looks back to Edmond.

"They certainly don't wanna lose it"

"Probably... But the real problem is that I'm feeling that they sent something worse after me than just lawyers"

Cecilia frowns.

"What can be worse than lawyers?"

"Times Square businessmen, maybe?"

"Girls, this is no joke. ZCorp has some really weird shit going on. They are gigantic. I'm kind afraid of what they are capable of"

He silences for a moment. Glances away.

"But... I couldn't let them just take away my work and... Vanish with it and use it who knows what for"

And looks straight into Elise's eyes.

"The only thing that came to my mind... Is that I had to give it to you"

Elise blushes oh so lovely.

And, as subtle as her raging horniness permits, she bites her lower lip as her pussy burns inside her NFL shorts.

"That was so dumb of you"

"Yeah, I guess so"

Looking up at Elise, still mesmerized by the alluring amazon that she had become thanks to his invention, her inviting muscles bigger than his wildest wet dreams, yet her face still so adorably cute, he concludes that his dumbness was more than worth it.

However...

C'mon, of course there would be a "however" here. What did you think? That they would meet up, go back to Elise's apartment, ignore the wreckage done by Vicky and end the night with a savage session of sex while our massive hotties use more vials and get incommensurably voluptuous and muscular?

Come to think of it, that wouldn't be a bad idea... But anyway, we have a plot to develop here.

However, Edmond's peace of mind doesn't last long, as the trio hears a low sound of something being launched out of a pipe. Then another two in sequence.

"Oh no"

Three grenades clatter on the asphalt near them. A heavy smoke immediately comes out of them, blurring their vision.

Elise shouts, scratching her eyes.

"What the fuck is that!?"

Suddenly, they hear two vehicles approaching at high speed, drifting and stopping next to them.

They wave their arms, but the smoke is so dense that they lost track of the Taurus lights.

The sounds of heavy footsteps are all around them.

"Ed *COUGH COUGH*, where are you!?"

"I'm still he-uhhhnnggg!"

Edmond's muffled screams become more distant, until they cease.

"Ed!"

As the smoke starts to dissipate, Elise and Cecilia finally get a grip on what's going on.

A bunch of armed men, dressed in black military uniforms, heads hidden by combat helmets and masks, are hastily retreating to a BMW and a large van. Two of them close the van's back doors with a heavy bang and head back to the front, while the car shoots away.

"Fuck! They're taking him!"

Cecilia squints her eyes.

"No, they're not"

Right before the van speeds off, she bends her enormous legs and grabs the rear bumper with both hands. Her biceps immediately swell, bulging a couple of inches (5cm) higher, and her thighs rips, deepening every carve of her quads.

"You're not going anywhere!"

She lets out a lustful groan as all her muscles tense and, standing up straight again, she lifts the back of the van clear of the ground.

The men on the front seats look at each other as the van tilts. The driver slams the gas pedal down, but the two front wheels skid on the asphalt, unable to break away from Cecilia's inhuman grip.

He looks in the side mirror and, well, he can't see much. She's behind the van.

So let's take the other guy's perspective, that drops out, drawing his pistol as he moves to the back of the van.

A much better view. Through his astonished eyes, we see our alluring, immense redhead holding up more than a ton of weight, her massive muscles fully pumped, her shirt and shorts glued to her imposing curves.

He knows what he's about to say is absurd.

"Drop the van! Now!"

Cecilia answers with an even louder groan.

But not any groan. A groan coming from a pain she's beginning to really, really enjoy.

The soldier can't help but lose track of his actions when Cecilia's body starts to tremble, her veins dilating on the surface of her pale skin.

"Ughhhh... Ooooh yesss!"

And, feeling a peak of pain blasting all over her body, her muscles begin to grow. The effort thrills her senses and fuels frantically her transformation as her chest expands, larger and wider than a small cabinet, her traps emerge, brimming with delicious distended veins, her enormous shoulders ripping, protruding like two pumpkins while her powerful arms keep enlarging under them. Her legs, instigated by her increasing dense mass and her boiling sex drive, thicken like crazy, stretching and making her taller, her enormous thighs reaching the girth of light poles.

Not standing a chance, her clothes strain and tear almost immediately, leaving her muscles in full, unashamed glory. Her delicious tits, free of any restrictions, balloon to watermelon proportions, pressing her hard nipples against the van's doors.

She moans in utter ecstasy as the van starts to feel lighter, her grip so powerful that her fingers begin to sink into the metal of the bumper, the pain quickly being converted into waves and waves of pure erotic pleasure.

The soldier's jaw just doesn't hit the ground because he's wearing the helmet. All his years of combat training are thrown through the window as he doesn't do nothing but passively stare.

Also stunned by the arousing scene, Elise takes a while to act. Shaking her head, she heads to the driver. Not knowing exactly how to proceed, she ends up giving him a clumsy punch. She had never punched a person before, but it is more than enough to knock him out. She reaches the key and turns off the van.

As the tire's noise cease, the other soldier finally snaps out of his trance. He points his gun to Cecilia.

And fires.

The blast brings Cecilia back to reality. Feeling something not harsher than a pinprick on her right shoulder, she lets go the van, which falls back to the floor with a tremendous thud.

Gazes to her shoulder. A small trickle of blood runs from the wound.

"You fucking shot me!"

She grunts as her trembling evolves to a strong shaking. As if reacting to the threat, her body starts to grow even faster. With the engine off, the awed man can hear the heavy, frightening flowing sound of her muscles expanding as she closes her eyes, overwhelmed by pleasure.

"Yessssss... Keep growing..."

Opening her dreamy eyes, she looks again to her shoulder and, with another spine-chilling feminine groan, the bullet pops out of it and falls on the asphalt, expelled by the sheer muscle mass filling her body.

Quivering, the soldier aims at her again, but, astonished by such scary display of beauty and power, his hands falter for just enough time for Elise to reach him. With a weird slap-ish blow, she sends him cold to the ground.

And has time to witness Cecilia's growth finale. As the bullet hole closes, healing in mere seconds, she is seized by a sensation of superiority so intoxicating that she's overtaken by a mind-blowing orgasm, her huge muscles shuddering in ecstasy as her sex squirts her love juices.

Our brunette can't help but feel a fierce hotness on her stomach, slowly making its way to her crotch. Naked and majestic, Cecilia exudes power and lust. Standing at an imposing 2.14m (7 feet), she's taller than the van, and not that far away from being larger than it.

Elise takes a long, deep breath.

Focus... Focus... Let's get Edmond and get out of here.

And gets closer.

"C'mon, Ceci! Open it up!"

"What...?"

"The van!"

"Gee, that's right. Edmond"

She opens the van's doors. Nobody's inside.

Cute, frustrated realization on both our heroines' faces.

"Dammit. The van was a decoy"

"What do we do now?"

"Well, we have two guys that can give us some information. If you haven't sent them to a higher ground. Or lower ground"

Elise is adorably unsure of herself.

"Of course I... Haven't"

Luckily for both, the supposedly hefty soldiers are alive and well.

Cecilia thinks for a moment.

"We better go to my house"

"Yeah. Better. If it's fine by you"

"But I think you'll have to drive the van"

"The van?"

Cecilia turns to the Taurus, her impressive muscles bulging involuntarily with every move.

"We won't fit. Even with one of them in the trunk"

Quickly agreeing, they have a really easy time putting them in the back of the van. A little harder to arrange themselves at the front.

Elise doesn't even bother to ask Cecilia to cover herself. She's not minding the view anyway.

And, finally, the five leave the rubber factory.

Five? Yep, five.

Hidden in an alley, away from the whole action, Josh observes the two massive beauties packing the van with the two men, then heading to the exit gate.

He turns on his bike and follows them.

Chapter 11

The van cuts smoothly through the night, carrying our two sweet amazons.

Smooth and firm. Well, at least that's the sensation both are having with their massive arms pressing against each other in the diminutive space of the front seats.

Settling down, Elise recaps the last events, her thoughts running wild.

Of course they would want the formula back, but soldiers!? Those corporations are really out of their minds. Or never had one... Bastards! They took my... Wait, what am I thinking!? Ed's not yours, Elise. But he kissed me... Oh, damn it!

15 minutes later, they arrive at Cecilia's house. The garage is wide, so they stop the big black vehicle inside, hiding it from curious neighbors.

Elise looks at Cecilia.

"Next steps?"

"A sandwich. I'm hungry"

"That can wait"

Points with her head to the back of the van. Cecilia sighs.

"Oh. Them"

They get out. Open the van's back doors. The two soldiers are still out cold.

"They may wake up at their own"

"Yeah"

Like a flash, Cecilia goes inside the house and comes back with two metal chairs from the kitchen. The van bends when she steps inside the trunk. Comes out, carrying the two sturdy men like they were grocery bags. Put their limp bodies sat on the chairs, then reaches for a large box in the garage. From inside it, she tosses two long ropes onto the floor.

With them, she ties the soldiers tightly on the chairs.

"That'll do"

"Hmm... I'm not sure"

Cecilia gazes at Elise. Then glances around.

A few useless metal bars are leaning on one of the garage's corners for years. The universal rule: if there's space, you keep it; if there's no space, you keep it anyway. Who knows, maybe we'll use them for something someday.

Cecilia grabs two of them. Stops in front of the tied soldiers. Gives one of the bars to Elise.

With her nonchalant confidence of which Elise always had a slight, healthy envy, Cecilia grips the other bar with both hands and positions it behind the soldier's back. A low, alluring groan comes out of her lips as the metal begins to bend, the huge muscles of her arms bulging prodigiously as she shapes the straight bar into an ellipse, trapping the man's upper body.

Elise blinks a few times. The casual display of power makes her pussy warm.

Finishing the second one, Cecilia admires the exquisite work, a subtle smile of proud on her face.

"Now, to my sandwich"

She turns around and heads towards the kitchen. Elise follows her, eyes glued on our redhead's naked back. Her ass is a monument of seduction, swaying lusciously from side to side as she walks.

The sandwich doesn't last a minute. She makes another.

Meanwhile, Elise finds herself in a difficult condition to plan the next steps. Her libido is buzzing to the point that watching Cecilia eating sandwiches is arousing her.

Takes a desperate measure.

"Will you stay like that?"

"Uhn?"

"I know none of your clothes will fit, but you can cover yourself with... Sheets"

"Why bother?"

Elise blushes.

"A little... Decency?"

Cecilia opens a mischievous grin. She gets it right away.

"All right. I'll get some sheets to cover these big... Round... Juicy boobs"

Grabs the bottom of one of them, felling the delicious weight of the soft, warm flesh, her hand slowly crossing the vast, velvety surface until it reaches her jerking nipple. Lets go an enticing sigh.

"Oh god, they're sooo much more sensitive now"

And giggles playfully seeing Elise's nipples almost piercing her shirt.

"I'll be right back"

Elise watches her redhead friend walking away sensuously until she leaves the kitchen, unable to take her eyes off of her. Finds and chugs a bottle of water in a futile attempt to cool down.

Damn, have I been bi all my life and I never noticed!?

I think the correct description, my dear Elise, is that you're now in a constant state of horniness that demands a tremendous amount of sexual activity to be slightly relieved, and this raging need is attracted by any sort of beauty, male or female.

In other words, you want to fuck. A lot. With everybody.

And, well, your rational side is fighting against it, but let's say it's kinda hard to win this battle.

Cecilia comes back dressed with two white sheets strapped to her chest and hips, purposely leaving the rest of her voluptuous muscled curves exposed.

And carrying the black box.

Yep. Before abandoning the Taurus in the abandoned rubber factory, they remembered to not abandon the remaining vials.

Elise gets anxious at the sight of it.

"Why did you bring it here?"

"You're the one always complaining about silly questions, so don't do it"

Cecilia opens the box, the glowing green and red dangerously inviting.

"There's some bad guys with heavy weapons between us and Ed. Better safe..."

And bites her lip.

"...and big than sorry"

"I'm not sure about this, Ceci"

And there's Cecilia's devilish smile again, as she gets closer and whispers on Elise's ear.

"Or maybe you don't care that Vicky keeps calling you pipsqueak"

Jackpot.

Pressing her lips in a cute impulse of anger, Elise grabs one of the green syringes, but then hesitates. Cecilia takes the syringe from her hand.

"Let me do it for you"

"Ceci, what if..."

"Shhh. Relax"

Cecilia gently holds her arm and sticks the needle, delighting with the fact that her massive shy friend is quivering with fear and excitement.

"You know, El, you could actually chose not to take this dose"

Stares Elise in the eyes.

"But you wanna take it, don't you?"

Elise doesn't answer. Her breath becomes quick and short, her mind a whirlwind of apprehension and... Desire. If she's barely controlling her sex drive now, what will happen if the new dose makes it worse?

The thought makes her soak her shorts with her love juices. And, yet, she doesn't do anything to stop the green liquid from flowing into her body.

Finishing the injection, Cecilia toss the syringe aside. Gives the black box to Elise and fills a jar with water.

"Now let's talk to those two"

Still shivering, Elise just nods.

Back to the garage, Cecilia takes their masks off. Her naughty nature halts her for a second; they are not bad looking at all. A slap of water wakes them both.

Obviously they can't hide their bewilderment. POV of their sights rising and rising through two towering female figures standing in front of them, apparently a NFL fan and an Olympus goddess, each more muscular than both of them combined, the peculiar clothes making everything even more confusing; it's like a muscle aficionado's weird wet dream coming true.

Cecilia has her usual playful smirk adorning her angelical face.

"Hello, fellas"

Sets her hands on each side of her waist in an intimidating pose.

"I was wondering here if you could help us with something. You see, that little guy your friends just kidnapped? He's a friend of ours. And we want to know where he was taken"

They remain silent.

"I get it. Part of the training, right? You're supposed to not reveal any information no matter the circumstances"

Elise suddenly gasps, her breathing becoming labored.

"Ceci..."

Cecilia grins. Steps to the garage's edge and grabs another metal bar. Turns back to the two men, a threatening glint emanating from her eyes.

"I don't think you realize the situation you're in"

Approaching Elise, she calmly takes the black box from her shaking hands and gives her the bar.

Elise tries to understand why Cecilia gave her the bar when a sharp pain strikes her chest. Her whole body tenses, making her hand clutch involuntarily the bar. It emits a small creak, but audible enough for the two soldiers to hear it. They keep their poker faces despite being on full alert inside by that little sound.

Cecilia watches the scene eagerly, thrilled by her last minute bar idea. But enjoying much more what comes next.

A loud rip warns that Elise's new transformation has begun, her back tearing a slit in her shirt by a sudden massive surge of muscles. Her heart races, pumping frantically her blood, spreading the serum that dilates every vein in its path, the scary network on the surface of her skin pulsating with the raw power that is building up fast inside her. She casts a hungry, frightful gaze at the soldiers before her eyes shut tight by another blow of pain. They swallow hard as they hear a dense sound of flowing coming from her shaking body.

Struggling to open her eyes, Elise looks down, feeling a pressure on her chest as the volume inside her constricting shirt begins to increase. A groan escapes through her clenched teeth just before her expanding boobs tear another hole on her shirt, the rip enlarging rapidly until it splits open, revealing two juicy boobs eager to grow more. Not done with the shirt, her arms and shoulders start to swell tremendously, straining and shredding the sleeves, the rags falling to the ground as her upper body is fully exposed.

The transformation suddenly goes full throttle. She trembles vigorously as her huge muscles erupt to even bigger proportions, traps emerging behind her neck, biceps rising and bulging with sheer power, abs hardening, her pecs broadening and enlarging her already enormous frame, the scary flowing sound continuing as her muscles are filled with more and more solid mass.

She moans, and moans, her sweet, girlish voice dragging the men's libido to surface like the Scorpion's spear. This time, the pain quickly turns into exhilarating waves of pleasure, traversing Elise's body like a raging river, her uncontrollable cries of passion making Cecilia bite her lip with lust.

Not noticing, she keeps squeezing the bar. Right in front of everyone's baffled eyes, it starts to bend, succumbing to her ever-growing strength. She releases it, running her hand to her thighs and caressing her humungous quads, felling them expanding, stretching her shorts until it gives away.

The bar falls to the ground with a loud, sharp noise, stating to the two soldiers that what they are seeing is no bullshit. They stare at it, jaws dropped, the shape of Elise's fingers distinguishable in the mangled cylinder.

Cecilia is all delight and playfulness.

"Do you see that metal bar, folks? That's what we are gonna do to your skulls if you don't start talking"

"Ughhh!"

"And it seems that she's not done yet"

The words make Elise's overwhelmed senses even hungrier.

So... Much... Power...

Her last drop of self-control falls apart with a harsh, lust-filled groan, the pleasure suffocating her words as her growth intensifies, approaching its peak. Unable to contain her wild desire, her delicate fingers make their way into her sex.

A chain reaction!

Lights out as the three spectators' brains brick by an explosive orgasm of our ex-petite, her shy, sweet cries so befitting with her old little self while her new immense body writhes in pure, unbridled ecstasy. She cums hard by her own rampant growth, her mouth opened in a silent scream as her muscles expand enormously in one final, breathtaking spurt.

Quick zoom on Cecilia's hand fondling her burning crotch, a sultry look in her eyes as she thinks about the many possibilities of savoring her stunning brunette friend.

Just a couple of deep breaths are enough for Elise's powerful body to recover. And for her conscience to come back.

She blushes adorably, realizing the depraved show she's put on in front of two complete strangers. Covers her privates with one hand and presses her basketball-sized jugs in a mouth-watering arm bra, her now 1.97m (6 feet 6) hourglass figure radiating erotic energy.

The soldiers' jaws remain on the floor.

"I... I..."

Cecilia puts the black box aside and steps in.

"I think we've made our point, in a very... pleasant way. Now it's your turn to cooperate"

Without warning, she lifts one of the soldiers with chair and everything, her bulging muscles displaying effortlessly their sheer power.

"Where are you taking Ed?"

"W-we don't know"

She presses the chair's legs, crushing the metal under her hands.

"I'm usually pretty easygoing, but I'm starting to lose my patience"

"We've been hired"

"Hired? Like mercenaries?"

He nods.

She glances to Elise.

"Those things actually exist?"

"Of course they do. They just don't advertise much"

"Ok... If you say so"

Glares back at the mercenary.

"And...?"

"Only a few individuals know the delivery point"

"And let me guess, you're not one of those individuals"

Elise's nerdy brain sparks right away.

"But... You know who hired you"

Cecilia narrows her eyes.

"That's a very good point. Who hired you?"

He remains silent.

With a swift movement, Cecilia keeps holding him and the chair in the air with just one hand as she clutches his head with the other.

"Time for the skull trick"

"Brandon. Brandon Balthazar"

Cecilia's eyes widen.

"Wait a second. The Brandon Balthazar?"

He nods. Cecilia glances to Elise.

"Wow. This is sooo deep!"

She doesn't answer, her cheeks still cutely red.

"See? It's not that hard to –"

Cecilia is a clever girl. She instantly finds it strange that both mercenaries are not staring at her nor at Elise.

She turns around and...

There he is. The sneaky, fit, not particularly bright Josh, holding a vial he's just stolen from the black box.

Suddenly, a familiar voice blasts from outside the garage.

"Throw it to me! NOW!"

Chapter 12

Let's hear it again.

"Throw it to me! NOW!"

Now let's have a quick recap before we continue.

There's Josh, following the large van with his bike until our massive duo reach Cecilia's house. Calls Vicky immediately when they stop at the garage.

Like a flash, she gets her bike and heads to it, but giving enough time for Josh to find a window and watch the movement. His fella inside his pants particularly enjoys the luscious naked redhead bending the metal bars like they were straws.

Vicky arrives. Sees Josh a little... Busy.

"What the fuck are you doing?"

He jumps. Hastily puts his dong back in.

"Where the fuck did you come fro..."

His jaw falls to the floor as he realizes that Vicky is much taller and beefier than the last time he saw her, which is not long ago, her bulging muscles stuffed in a tiny shorts and an overstretched sports bra that are barely leaving anything to imagination.

"My bike broke down a few blocks away, so I walked. I braked hard in one corner and ended up ripping the handlebars off"

She glances inside. Sees just the tied mercenaries.

"Where are they?"

"W-Went to the house"

Look to the jerking bulge between Josh's legs.

"How big are they?"

"Uh... Big"

It's absurd what he has to say to the muscle freak in front of him.

"Maybe bigger than..."

"For now"

A cold sweat breaks out on his forehead.

"You wanna get... B-bigger?"

She gazes down at him, alluringly commanding.

"I don't want. I will"

He feels like shrinking. Except for his cock, that feels like about to explode.

They hear a sound from the garage. Elise and Cecilia come back.

Vicky tries, but can't hide her shock by how enormous they are. The majestic redhead covered only with sheets is definitely bigger than her, and her brunette neighbor is not that far away. Zoom on their huge boobs bouncing slowly by their own sheer weight with each step, like subtle trepidations in the water.

Her eyes lock immediately on what Elise is holding.

"That box. It must be it"

Looks back (and down) at her boyfriend.

"You're gonna sneak in and grab that box for me"

Inside, Elise suddenly gasps, her breathing becoming labored.

"Ceci..."

And Vicky's plan is forced to be put on hold for a moment as both halt, watching through the window Elise's muscles and tits bursting through her shirt, exposing her massive back that enlarges in front of their eyes, broader and fuller by the second, carved and ripping with rigid mass, her neck hiding behind her towering traps. As she moans passionately and gets bigger and bigger, she drags everybody's excitement to surface.

And I mean everybody. Outraged, Vicky snorts in anger as she can't control a warmness in her stomach, her sex tingling and moistening, inevitably aroused by the steamy scene. As Elise reaches a thunderous climax, Josh almost blanks out, blowing his load among with her.

When her transformation is over, Vicky is greedier than ever.

You won't be bigger than me, pipsqueak!

She suddenly grabs Josh, lifting him as easy as a pillow and squeezing him through the small window.

The little man (compared to the three amazons around) ducks in panic behind the van, then crawls towards the black box, taking advantage of Cecilia and Elise's distraction with the interrogation. To be sure, but much more out of curiosity, he opens the box.

The shiny glow of the vials amuses his limited brain.

Grabs a green one. And stops paying attention to his surroundings long enough to be spotted by the mercenaries.

Swallows hard when Cecilia turns to him at the same time that Vicky's voice booms from outside.

We are back to synchronized action!

In his typical dumb instinct, Josh leaves the box and throws through the window only the syringe he's holding.

Cecilia runs over him like a train, sending him flying to the side of the van, and blasts through the garage's door like crossing a curtain.

Vicky is standing in her garden. Has the emptied syringe plunged on her arm and a vicious smile on her face.

"Too slow, numbsk–"

Vicky's eyes widen when a punch hits her chin like a sledgehammer. She falls unconscious on the grass.

Inside, Josh collects himself enough just to find Elise looming over him, the immense naked brunette still covering her privates with a cute angry expression.

He frowns.

"Please be gentle"

She loosens her delicious arm bra to give him a quick slap, putting him to sleep.

Cecilia comes back, crossing the hole in the garage's door carrying Vicky on her back.

A neighbor shouts from next door.

"What the hell was that noise!?"

Cecilia puts her head out.

"Late shift"

"Go to sleep, god dammit!"

Looks back to Elise.

"He's grumpy like you. We're good"

"I would be annoyed by wood exploding right next to my house in the middle of the night"

"You worry too much"

"Where's the vial?"

Cecilia drops the empty syringe on the floor.

"She was fast"

Elise screws decency, leaving her goodies in full view, her hands closing into fists in pure, adorable rage.

"This bitch!"

"Let's take them inside"

They go to Cecilia's living room. Toss the couple on the floor.

Elise is still furious.

"I can't believe she did that... Again!"

"Well, I can't believe what the mercenary guy said. Brandon Balthazar! Can you believe it!?"

"Brandon Balthazar, the owner of WeAI, the biggest tech company in the world, responsible for the fanciest and most expensive smartphones a fanboy can buy, known by basically every person with an internet connection, that I'm remembering with this ridiculously detailed and inorganic description so the readers can know who he is?"

"Exactly!"

Vicky suddenly groans, moving slightly her head.

Cecilia clicks her tongue.

"Nope"

She quickly opens a drawer and grabs a small flask and a cloth. Soaks the cloth with the liquid inside the flask, knees and covers Vicky's mouth and nose with it. She immediately becomes still again.

Elise just watches.

"What the hell did you just do?"

"Used chloroform to keep your BFF napping"

"You did what!?"

"It really comes in handy when I misjudge a date that I bring here and he's an asshole, or boring"

"You're hopeless"

Cecilia gets up. Even after Elise's last growth, the voluptuous redhead is still towering over her.

"Safety first. We girls have to watch ourselves"

Throws a bicep flex, the massive veiny globe doubling in size, larger than a handball.

"Although I don't think I'll need it anymore"

Elise brings back her arm bra, hiding her erecting nipples from Cecilia's playful gaze.

While they are distracted, something starts to happen, right under her mountainous tits.

Vicky's fast asleep. But her body... Oh, her body is not.

Subtly, her muscles begin to react to the serum. Her veins slowly dilate under her skin until they get visibly, frightfully distended.

Elise's oversensitive body, which includes her delicate bare feet, feels a slight trembling on the floor. She looks down, has to take a step back so her enormous boobs don't block her view.

"Oh no. It's still happening"

Cecilia instead bends her upper body to get her jugs out of the way.

"I think it's true after all"

"What is true?"

"When we train, we actually buff up when we're sleeping"

Both are staring at Vicky when she begins to grow, her muscles straining her already tight clothes, surging from every portion of her body.

Elise glances up at Cecilia.

"She haven't trained!"

"You said she trains all the time. "That dumb gym rat" and stuff"

"I mean she haven't trained right now!"

"Well... It's obviously working despite of that"

They are forced to turn their attention back to Vicky when a loud rip snaps her sports bra in half, revealing two tiny tits on top of really, really large pecs. The trembling intensifies as her body stretches, making her taller, giving more room for solid mass to keep blooming.

"Fuck! We have to stop her!"

"What do you suggest we do? Drain her blood to suck the vial out?"

"Eeww, that's disgusting"

And, unable to do anything, Elise and Cecilia just watch Vicky's growing muscles taking up more and more space of the floor, shredded and brimming with raw strength. Her boobs slowly disappear, merging with her titanic pecs, her humungous chest getting taller than the center table, sculpting further her bodacious hourglass shape as her waist keeps slim, swelling just on the right places, carving deeper her rock-hard 6-pack and obliques.

Little by little, her shorts are reduced to panties as her thighs get astoundingly thick, until the erupting mounds of mass tear the fragile fabric, revealing a shaved pussy with a pointy, swollen clit. On the upper body, her enlarging shoulders finish ripping her top, her mighty body fully, deliciously naked.

And growing more.

Elise grabs the cloth from Cecilia, drenches it with chloroform and presses it on Vicky's face.

"Here, take some more"

She shivers as she feels her strong trembling, the power flowing inside Vicky's expanding body giving her goosebumps.

Taking the cloth away, she stares at her relaxed expression, serene like Elise has never seen, unaware that herself is getting tremendously big.

And, as smooth as a summer breeze, her transformation gradually comes to an end. The result is a 2.14m (7 feet) statuesque Vicky lying on the living room, like a muscle goddess fallen from heaven. Her boobs have vanished, completely absorbed, leaving only her hard nipples adorning her gigantic fem pecs, her traps so big that the lower part of her head is resting on them, her thick veins pulsating steadily, pumping blood to her massive guns.

And surrounded by two other goddesses, which makes this ordinary suburban house a mini Olympus on Earth.

Cecilia is... Well, the usual Cecilia.

"Who would say that a girl with big pecs for tits would be so hot?"

"Please don't. Not about her"

BUT! (yes, with caps an exclamation mark)

Deep inside there is Elise's raging horniness, and even her can't help having wild thoughts about Vicky's colossal curves.

She looks away, avoiding the sight of the two gorgeous amazons. Takes a deep breath.

"We still have a mission to finish. Time to meet the richest man in the world"

Chapter 13

Elise is thinking about the next steps. Zoom on her adorable concentrated expression, but not too much zoom, so we can also see her glorious rack and the delicious bulging muscles of her upper body.

"We must get rid of them"

"How?"

"I don't know. Dumping them somewhere?"

Realizes that Cecilia's voice is distant. Turning around, she finds our redhead coming back to the living room, bringing the black box.

"Now what?"

"You had three spurts, then it stopped. I had three spurts, then it stopped. With this shot you just had, you must have two more spurts"

"That's a poor empirical conclusion"

Cecilia takes a vial from the box. Elise's overly cautious side can't help but manifest itself.

"You took two at once. Maybe yours is not over yet"

Cecilia's devilish smile appears, her beautiful eyes sparkling with an unmistakable hint of naughtiness.

Plunges the needle on her arm.

"Just in case"

Elise watches the glowing green liquid entering her veins with a mix of apprehension and arousal.

Letting go an alluring sigh, Cecilia's eyes meet Elise's.

"I have an idea"

Cecilia has an idea. Always dangerous. Let's see.

"There's something we haven't tried yet. And we have two guys awake"

"So?"

Cecilia comes closer. Playfully lowers her voice.

"Don't you wanna know how it feels to grow... You know... When you're banging?"

"You can't be serious. One of them shot you!"

"They're handsome, athletic, and I'm sooo fucking horny"

She slides her hand on Elise's rigid 6-pack. Elise shivers.

"And I can tell that you are too"

Elise closes her eyes as Cecilia's hand reaches her crotch.

"Don't be that boring Elise that leaves me at parties at 9PM"

"You're always with someone by then. I'm the one alone"

"You're alone because you want. Rowan is looking for you all the time"

"Fuck you! I rather eat glass than hook up with him"

"He will probably pass out if he sees this big, sexy body of yours right now"

Cecilia knows very well when Elise gives up. She puts her mouth strategically near Elise's ear, her enormous, soft boobs embracing her arm.

"C'mon girl, let's have some fun"

Cecilia grabs Elise's hand, smiles seeing the cute blush in her cheeks she always gets when convinced to do something misbehaved, or naughty, mostly by her. Drags her back to the garage.

"Hello again, fellas"

With sensuous yet heavy steps, they stop in front of the mercenaries.

"El here reminded me of something. One of you shot me, I don't really remember which of you"

They clearly get worried.

"I should rip you both apart, but I guess this is your lucky day"

She lets the sheets covering her godly body fall, then shakes her red hair, leaving a strand in front of one of her eyes, as she loves to do and we love to see.

Both mercenaries have their eyebrows fully raised.

She kneels with a heavy thud in front of one of them. Pull his trousers down, and his dick pops out, hard, pointing straight up.

"Seems you're ready to go. Well, how could you not?"

Starts stroking his cock with unashamed eagerness.

"What a delicious friend you have"

As impish as ever, she licks the shaft all the way to the top, then engulfs the cockhead with her hot mouth, her alluring moans muffled as she works his manmeat down her throat, then proceeds to give him a wild head.

In front of the other mercenary, Elise hesitates for a moment. But, seeing herself towering over him, a tall, strong guy but nothing more than a weakling compared to her, her chest heaves. She slowly approaches, positioning her humungous legs on each side of the seated man. Her hormones are boiling, but she stays in silence, waiting, her stiff, carved abs on his mouth's reach. Her natural, sweet scent inebriates the mercenary, which, as cautious as possible, kiss her bulging 6-pack just above her cute belly button.

Elise shivers, her ultrasensitive body sucking in the stimulus as he begins to travel over the rock-hard hills with little kisses. Her self-control is barely holding up when the mercenary's lips slide down and finds her sopping pussy.

The soft touch of his tongue on Elise's clit sends a shockwave of pleasure all over her massive muscles. Awakes something inside her. Something feral. She grips the metal bar trapping him and snaps it as if it was a candle.

The harsh noise of metal cracking catches Cecilia's attention. With a loud pop, her mouth releases her mercenary's cock just in time for her to watch Elise tearing the ropes, freeing partially her captive (after all, he's still between her immense thighs).

Thighs that begin to press him harder as a familiar, ravishing sensation starts to rise. Taken by a violent urge growling inside her, Elise stares down to the mercenary like a starving beast.

Cecilia's eyes glow with mischievousness.

"C'mon, El. Say it"

Elise girlish voice comes out low, quivering with desire.

"Fuck me hard or I'll crush you"

Her veins pop, so distended that the man can feel the blood flowing through them. He tries to undress, but too slow for Elise dire needs; with her bare hands, she clutches and shreds his body armor, jacket and shirt. The fright makes the man throw his body back, falling to the ground, Elise tossing the chair away right after. She's about to bend down when she's overcome by a tremendous surge of muscles. Through a ragged, lustful moan, we see pure, dense mass invading her chest, arms, legs, shoulders, traps, enlarging them, shaping them to majestic proportions as she gets taller, sexier and much, much beefier.

Cecilia bites her lip, stroking unwittingly her mercenary's dick. He involuntarily thrusts his hips forward. Her voice comes threatening and passionate at the same time.

"Don't you dare to cum"

And keeps staring wantonly at her massive friend.

Collecting herself, Elise's sparkling eyes lock on the mercenary, her titanic body shaking as she struggles to keep the growth at bay just enough to... Well, to put Cecilia's idea into practice.

Even as utterly aroused as she is, her cheeks get red as her trembling hand reaches his trousers and tears them, revealing his rock-hard dick.

She groans in anticipation, breathing heavily as the serum keeps trying to make her bigger, her boiling blood dilating her veins even more. She bends her knees and, with no ceremony, mounts on him, gasping as the first inch/cms of his member penetrates her sex.

Forcing the shaft deeper inside her, her growth comes back at full throttle. The mercenary grunts as her pussy walls squeeze his cock, his eyes widening as her frame enlarges on top of him. Elise shudders, moaning enticingly all the way down until his whole tool is engulfed by her love canal.

This is candy to our naughty redhead. Sweet, triggering candy.

"Oh, El, you have no idea..."

A harsh groan escape her lips.

"...How much you're turning me on right now"

She abruptly frees her mercenary in the same rough fashion as Elise, ripping the metal bar and the ropes in one pull. The muscles on her arm bulge, but not from the effort; she opens a wide smile as she feels the serum kicking in, swelling them even more.

"Oh yesss, come to me"

She places the mercenary standing on the chair while pushing them both until they're leaning against the garage wall.

The mercenary looks down, to the mountain of muscles above him, staring at the seemingly endless cleavage of her gigantic boobs, her puffy nipples jerking in thrill.

Cecilia gazes up at him, smirking.

"You must be feeling tall now, don't you? Urrrr..."

As her muscles bulge frightfully, she slowly gets taller. He swallows hard as, even on top of the chair, he watches her keep growing until their eyes meet. They stare at each other, her expression dripping superiority and confidence, her muscles still trembling, warning that they're not done.

Her voice comes out serene, but carrying a subtle menacing tone within it.

"You better fuck me real good, little man"

She turns around, bends forward and raises her hips, giving the lucky guy a heavenly view of her ass and her soaking pussy, just waiting for him.

"Now get to work"

He instinctively grips her buttocks and aims his member at her sex, the hot, tight confinement inviting him to go further as his cockhead is pressed by her powerful pussy walls. She purrs lusciously, overcome by spasms.

"Shove it deeper... Urrrrrrrrr"

As his dick works its way inside her, the serum, boosted by her boiling libido, starts to really take effect. He pulls his hips back to stick it in again but halts, mesmerized by her back, the muscles moving visibly as sheer mass is blooming inside them.

Cecilia is too aroused to wait.

"The extra stimulus... Urrrrr... Is definitely working..."

Clutches his hips with a fraction of her strength, which is more than enough to trap the mercenary.

"So FUCK ME HARDER"

Utterly scared and excited, he promptly obeys, pounding her as fast as he can. She groans.

"Yessss"

And grows.

"Keep gooooing"

With each thrust, Cecilia gets bigger, and bigger, her upper body broadening, three times wider than the not-so-small guy behind her, her traps towering under her long ginger hair, the triceps and biceps enlarging her already enormous arms, each one thicker than the torso of the about-to-faint guy behind her. As her tree-trunk legs get longer, he has to stay on his tiptoes to keep going, her ass expanding right under his hands, firm and yet juicy, her pussy tighter and tighter around his cock.

Craving for more, she pushes him back and bangs him on the garage wall, almost squashing him. She does it again, and again, cracks surging behind his back and going all the way to the roof as she forces his prick deeper, bouncing her huge jugs that swell prodigiously, larger than watermelons, her pretty, freckled face expressing pure erotic bliss.

Watching Cecilia getting seriously big, Elise loses it. The last drop of inhibition is swept away, the serum flowing on her veins mixed with her raging sexual drive bringing out a depraved nymphomaniac that she didn't know existed within her. She got carried away with Cecilia in her bed a couple of hours ago, but now...

Rising her hips, she comes down heavily on the mercenary, burying his big rod deep inside her, and gasps to the sky as she feels her muscles exploding with growth, pressing against each other, elevating her to goddesshood. There's no pain anymore, just pure ecstasy, the intoxicating sensation of dominance impossible to ignore, and yet her shyness is still showing on her scarlet cheeks, making her adorably sexy as she begins to fiercely ride the mercenary.

She stomps her hands on each side of him, smashing the floor, the chunks of concrete bouncing as she pounds him faster, harsher, her tremendous weight increasing by the second, threatening to sink him on the ground.

The serum is not just acting on them. They can feel it, as clear as a taste or a smell, merging with their bodies, filling her cells with power, converting it into muscles, tits and pleasure, defying their very understanding of pleasure.

Our two cuties' eyes meet one last time, their gazes so full of lust that they seem to electrify one another. After that, there's only their yelping cries of passion and the frightening sound of their expanding bodies and savage sex filling the garage, melting the mercenaries' brains.

Until the deliciously inevitable reaches Elise.

"Oh fuck, oh fuck, I'm gonna..."

And Cecilia right after.

"Me too. Me toooooo OH MY FUCKING GOOOOOD"

And the symphony of their sweet moans echoes through the neighborhood as they are struck by the most mind-shattering orgasm of their lives, while their lovers collapse of exhaustion.

After panting briefly, collecting herself astoundingly fast, Elise stares in astonishment at the damage she has done to the floor without making the slightest effort, then at her own hands, still thin and delicate, and forward to her forearms, ridiculously large, covered with veins, the solid mass stretching her soft skin. Shivers with the raw power pulsating inside her muscles. Stands up, feels taller, is taller; a monumental 2.09m (6 feet 10) hourglass-shaped brunette who can make someone come just by looking at her.

Which, as crazy as it may seem, is not the biggest girl in the room. There's a super-busty redhead, towering above her at 2.22m (7 feet 3), already fully recovered, looking at the remnants of her mercenary, lying like a rag doll on the ground. She has a disappointed expression and her hand casually caressing her gigantic thigh.

"Done already? You men are so puny"

A male voice shouts from outside.

"You bunch of perverts! I'm calling the cops!"

Cecilia turns to the garage's window.

"No need to"

And continues, lower.

"They won't be able to do anything anyway"

Glances to Elise, who looks away in adorable shame.

"I... I don't know what came into me..."

"I know"

Devilish smile.

"I know quite well"

Elise blushes, her tingling privates saying yes, you know quite well.

Cecilia sighs.

"Oh god, I'm still sooooo in the mood. I could fuck everyone around, including the narrator"

Well, I really wouldn't mind that.

Anyway. Kind of the party pooper here, but there's a mission to finish. Time to get them into the van and...

Elise startles.

"Shit! Vicky! How long have we left her alone!?"

Dashes to the living room.

And...

...

...

...

...

(exaggerated amount of ellipses to give a forced tension)

...

...

...

...

Luckily, Vicky and Josh are still there, unconscious.

Relieved, Elise hears Cecilia calmly approaching, the ground vibrating with each of her steps.

She stops next to Vicky.

"If it was up to me, I would wake her up just so she could see us grow in front of her. And then, who knows, maybe check if her muscles are as hard as they lo–"

"NO"

"All right, all right. Dump them, right? Ok, we can dump them"

Back to the original plan. Our massive cuties will certainly be more focused on saving Edmond after this enjoyable intermission.

Or even hornier, which is scary. And really exciting.

Chapter 14

Cecilia waits, standing in front of Elise. Her enormous muscles throb with power without her even moving, her thick veins sticking out as if concrete is flowing inside them. Her thighs are pressed together, hiding partially her sex, her left hip slightly higher than the right in a casual pose that exudes femininity and lust. Her nipples are still hard, adorning her humungous boobs and giving the delicious certainty of her horniness.

Elise knows the enticing danger lurking around her, so she focusses on Cecilia's freckled face, avoiding her heavenly curves and muscles as best as she can.

"Don't even try that look on me"

Cecilia has bedroom eyes. Elise stays firm.

"We're not going out naked"

Cecilia gazes up, huffs like a sulky kid. Her head is not that far from the ceiling.

"Aww, it's so much more comfortable this way"

"Go get some other sheets"

"I'll keep the ones I was wearing in the garage"

"No. I'll have them. You'll get new ones for you"

Cecilia frowns.

"Are you doing this so I won't be alone with the mercs?"

"Exactly because of that"

Cecilia makes a lovely grimace.

"Boring El is back. Booo"

Turns around, her ass swaying lusciously as she heads to the closet, her dainty feet producing alluring tremors with each step.

"They're wasted anyway"

Indeed, Elise finds the two men still depleted on the garage's floor. Gazes to the mangled iron bar, to the shredded clothes and body armors, to the cracks on the wall.

We did that... Without even trying...

A shiver crosses her spine.

Curious, she shyly arches her back forward and holds onto the van's bumper. Just the act of standing up straight again is enough to stretch the shock absorbers until the rear tires leave the ground. She blinks a few times, still finding hard to process what she has become.

Carefully, she puts the van down, no effort at all; it wasn't even a challenge for her new, powerful body.

A gentle night breeze comes from the enormous hole made by Cecilia in the garage's door, caresses her sensitive privates. Reminds her that, even quite extreme, the sex session they just had didn't come close to satisfying her.

She glances down, finds her enormous jugs, nipples fully erect again, then the mercenaries. Bites her lip discreetly, her eyebrows arching adorably.

They are actually handsome...

In a sweet mix of doubt and shame, she brings her hand to her crotch, her delicate fingers massaging her enormous thigh. Her muscles react, getting warmer, bulging slightly by an uncontrollable excitement, her body craving for more pleasure.

Out of nowhere, a sneaky memory pops into her head.

Edmond's kiss.

As if it happened seconds ago, her aroused mind brings the unexpected event so vividly that makes her insides burn.

Oooh, Ed. Why you're not here right now...

She sighs with unquenched need, squeezing the rock-hard flesh of her quads, feeling the blood rushing inside her pumped veins.

And jumps when she notices Cecilia standing next to her. Our brunette was so immersed on her... entertaining thoughts that she didn't hear the huge redhead approaching.

"Well, well, looks like it's time for me to be the voice of reason"

Elise flusters instantly. Cecilia grins.

"Or should we rise them up for a second round?"

"N-no"

Besides the ones covering her godly body (partially, I must say; she put no effort in covering it properly), Elise finds four other sheet rolls with Cecilia.

"Extra sheets. Well thought"

Hastily grabs the sheets from Cecilia and covers the mercenaries.

Cecilia's smile is terribly captivating.

"New El is still there. Nice!"

"You go get the bitch and her boyfriend"

"Sure thing. You hold yourself there. Or don't"

Elise glances away as Cecilia leaves, cheeks still red. Wraps her privates and tits with the sheet, the touch of the fabric rubbing her soft skin keeping her on the edge. Shakes her head.

C'mon, Elise, focus! You won't think any more about how much you want to have... You know what with Ed. You have to focus on saving him. Yes, saving him! Get him to safety, so then you can have... Oh, fuck, this is not working!

This time Elise notices Cecilia coming back, mostly because the redhead breaks down the wall around the living room's door while carrying Vicky and Josh, one on each shoulder, crossing the concrete as if it was a curtain. Shakes the dust and debris casually.

"These tiny houses are definitely not suitable for us anymore"

Elise watches mouth agape as she drops the little guy (compared to them) and the immense blonde, that hits the ground with a frightening thud.

"Well, let's tie them already"

"Uh, I thought about just leaving them somewhere far away. We would need a lot of..."

"My chad Terry works in the moving business, remember? He leaves his stuff here because my garage is bigger. There's enough ropes here to tie a T-rex. Pretty convenient, huh?"

Cecilia turns her head and winks at us.

Elise has no objections.

"Ok then"

Turning around and pulling a large tarp, Cecilia reveals a mile of sturdy ropes.

"And there's also the bars"

Lifting them like ragdolls, they quickly tie the tree men, then proceed to Vicky. There's so much muscle mass that they don't bother trying to cover them with the sheets; her upper body is so large that they have to "tie" the metal bars together in groups of three in order to strap her arms and chest. What only industrial machines can do, our sweet girls do with their bare hands, as if they were molding clay.

When they're done, Vicky looks like a huge, weird modern statue with the head of a pretty, don't-mess-with-me blonde on top.

They throw the four on the back of the van and get to the front seats. The hefty vehicle lowers by their sheer weight, struggling to start moving.

To dump them, they head to [insert a remote location of your choice with a light source; don't forget it's still midnight and, trust me, you want to see what will happen with them, specially one of them].

So, while our two beefy heroines drive away to meet Brandon Balthazar, let's switch the focus and advance fifteen minutes.

In the remote location you chose, all we can hear is Josh's yells.

"Babe! Babe! Wake up!"

Instead, he wakes up the two mercenaries. They try to release themselves, but to no avail. Exhausted, they stop struggling.

The three guys just stay there for another couple of minutes, observing the mountainous body of Vicky lying motionless, so wide that it creeps up to the height of a fire hydrant.

Until they feel a slight tremor on the ground.

Vicky's eyes open at once.

She awakes not because of Josh, but because something else is awakening, building up inside her chest. Something big.

She scans the surroundings silently. Tries to move her arms. They don't budge.

Realizes what Elise and Cecilia had done.

"You two little bitches"

Although saying it to herself in a subtle whisper, Josh hears it.

"Finally, babe! Uh, don't think us wrong and shit, but we need your help. Maybe we can get rid these ropes if you come closer and..."

He babbles and freezes as she raises her upper body at once, snapping some of the ropes. The bars creak, but hold up. Josh expected to see her absolutely furious about what is going on, but she has an unexpected serene expression that makes her more menacing than he has ever seen her before.

The ground shakes again, an unnatural quake coming from the imposing blonde as a dense flowing sound reach their ears. Through the gaps of her improvised straitjacket, they see her muscles pulsing, forcing the bars that creak louder.

"Do you really think..."

A brief groan escapes her mouth.

"...that these strings and sticks..."

Another groan, harsher, feral, comes out as her whole body trembles vigorously.

"...will restrain ME!!!?"

The irises of her eyes shrink, sparkling with her unleashed rage as her groans evolve to a feminine guttural roar coming through her clenched teeth. Shaking frightfully, her muscles begin to swell, filling her confinement to the limit with steel-hard mass, her exposed shoulders and traps expanding around her head.

The overwhelming pressure starts to bend the bars, her continuous howl mingling with the sound of metal cracking as her monstrous upper body starts to burst through, the first broken bars falling to the floor. The rest follow quickly as she violently stretches her arms, sending debris flying in all directions, the dense flowing sound intensifying as her biceps and triceps tremble and bulge, bigger and bigger by the second.

The legs are last. She could rip the remaining restrictions with her hands, but she stays still, waiting for her growing quads to break and snap them solely by packing so much mass that the bars and ropes simply can't hold back, her pussy squeezed between her thighs soaking wet with lust.

With two thunderous stomps, she stands up. The grunts cease. Her expression becomes calm again, just showing a tiny, vicious grin as she welcomes the rest of the spurt, her colossal body free to grow taller, wider, her eyes glowing by the tremendous power feeding her muscles.

The three astonished men feel one final quake before the surge ends, a soundless, alluring "yesss" forming on Vicky's lips as she feels her stupendous muscles relaxing, but still swollen like she just finished a fierce workout, her frame inhumanly projecting up and to the sizes, a 2.21m (7 feet 3) monument of beauty and brutality.

With a slow, deep sigh, she fills her chest with the night's air, her massive fem-pecs thrusting forward, taking her time to savor the awe and fear of her spectators.

But, as the thrill slowly fades away, the insatiable power hunger of our gargantuan blonde immediately growls inside her.

With two heavy steps, she looms over the hopeless mercenaries.

"Brandon Balthazar hired you because of the serum"

Clutches and lifts them, one with each hand.

"If you want to keep all your limbs attached to your bodies, you're gonna say right now where I can find more of it"

"ZCorp. It's from ZCorp"

"Hum... Must be the company where the pipsqueak's boyfriend works"

She stares at them, deadly threatening. Drops them.

"Time to go"

Josh startles, trying to hide the boner he got from watching his dominant girlfriend in action.

"Y-yeah"

He looks around the vast nothing of the inhospitable place you chose them to be.

"But how the hell we'll get out of here?"

Oh boy. We really have to give Josh a push sometimes, don't we?

Josh, just look at your girlfriend's legs.

Josh glances to the two magnificent pillars of muscle under Vicky's hips.

"They're wonderful, and huge. So?"

Don't you think they can endure some serious effort?

"Y-yeah"

Vicky's mind lights up. She grabs and puts Josh under her arm, almost crushing him.

"That's true. I don't need bikes, or cars, or anything else, ever again"

Her veins pop up just before she starts running, each step hammering and cracking the ground as she accelerates, first gaining momentum, then faster than any human has ever reach on their feet, crossing the deserted random area they are like a locomotive. As she dashes towards civilization, she has just two thoughts on her mind.

More serum. Much more. And those two bitches begging for my mercy.

Chapter 15

"Oops"

"What was that, Ceci?"

"I ripped the handle off"

We catch up with our delightful duo just as Cecilia is having a bit of trouble getting out of the van.

Both agreed that showing up at Brandon Balthazar's house with a special-ops van would call too much attention (as if two huge muscular amazons wouldn't, but anyway), so they parked nearby. Elise drove, as Cecilia's ginormous breasts have made this simple task... Permanently unfeasible.

The redhead doesn't think twice. Rips the whole door off.

"Products keep getting more fragile nowadays"

The van sways vigorously as she gets out. She stretches her splendid body, her head higher than the vehicle's roof, the sheet tied around her chest almost coming loose. Tosses the door away like an empty soda can.

"Planned obsolescence, they say"

Elise just drops out normally, the bumpers creaking, finally relieved of their sheer mass.

After a 5-minute walk in the dark of the night, they reach Brandon's mansion, which, just like in Hollywood, conveniently has no walls, fences or–

"Hey!"

Elise looks at me.

"Don't you think you're using this "convenience" thing a little too much? I mean, we can definitely handle some action now"

.........Ok. I guess so.

Cecilia bites her lip while smiling in pure playful thrill.

"I'm just lovin' this new El"

All right. Here it goes.

They reach Brandon's mansion, which looks like a stronghold. Fourteen mercenaries are spread around the perimeter, eight on the low-grass outside garden, six on the two guard towers of the enormous concrete wall that surrounds the three-floor house, all of them heavily armed.

The girls find a hiding place in a small grove a few meters from the wall. Elise peeks out from behind a bush.

"Ok. Let's focus on the best course of action here"

"Focus. Of course..."

"The eastern part seems to be quieter. I think we can–"

Elise halts. A few seconds of distraction and Cecilia is out of the bushes. She whispers furiously.

"Ceci!"

As expected, Cecilia ignores. Her frisky voice rings out alone in the silence, the mercenaries' attention immediately drawn to her.

"Good evening, guys"

She comes to view, completely in the open.

"These night shifts suck, uh? You must be so bored..."

They raise their guns, deeply confused. I would be too, I think; out of nowhere, there's a redhead muscle goddess more than 2 meters (6 feet 7) tall, her curvaceous attributes barely covered, walking seductively in the garden.

This statuesque perfection proceeds to take the top sheet off, revealing two round, juicy, massive boobs, each one larger than their helmets, the pointy nipples jerking hypnotically.

And so they are graced by her devilishly smile.

"That's why I brought a little show for you"

Suddenly she raises her meaty arms.

"AAAHH!"

And pounds the ground with both hands.

Closer to Cecilia, Elise's eyes widen and she almost lose balance as she feels a tremendous pulse passing like a flash beneath her feet, rippling the ground in its path, the trees of the grove shaking vigorously.

The shockwave continues, reaching and sending the garden mercenaries into the air, then hitting the fortification like a wrecking ball, knocking down the rest of the squad on the guard towers and cracking the concrete walls. Far away, we start hearing car alarms as the earthquake made by our redhead keeps going, the loose leaves from the trees falling slowly to the ground in the brief moment of calmness that follows.

Cecilia stands up. Gazes to Elise with a mocking grin.

"My plans work too!"

Not aware that the men are quickly recovering. Elise notices.

"Ceci, Watch out!"

Cecilia turns back to the squad. Without a second thought, they open fire, hundreds of bullets coming out at once from their M4A1s.

Elise stares astounded at the scene.

Cecilia is... Giggling.

"Haha, it tickles"

One by one, the myriad of projectiles is stopped by her velvety skin, unable to pierce her rock-hard muscles.

She then begins to menacingly approach the wall.

"It's no use, guys. Your friends already tried it and it didn't work"

Her lovely, devilishly smile widens.

"And I was smaller than I am now..."

She keeps advancing, the bullets falling around her impenetrable body like a steel rain.

"But if you want to– Hey!"

Rubs her eye.

"Not in the eye! That's low!"

Blinks a few times, a cute angry expression surging on her face.

"You better not try that again"

They keep shooting, and she keeps coming, her muscles frightfully swelling from the continuous blows, until they empty their magazines.

In the silence that takes place, they hear the twisted sound of the damaged front gate opening. The mercenaries promptly retreat, sheltering behind the wall.

A soundless "wow" forms on Elise's lips, astonished by the inhuman event that just took place.

This is... Crazier than crazy...

She slowly comes closer, staring at Cecilia's immensely broad back, her huge traps hiding her neck, her long, wavy red hair cascading on her chiseled muscles, a carpet of bullets behind her. She can't help but feel a twinge of arousal between her legs.

Stands side by side with Cecilia.

"I... Guess you're ok?"

"Yes I am. How about you?"

"I'm... Fine"

Cecilia gives Elise her unmistakable bedroom eyes, the heat of her pumped muscles palpable.

"Just fine?"

Our sweet brunette blushes adorably.

"Y-yeah"

"I feel like I could fuck this whole squad, if they hadn't fled like a bunch of–"

She stops talking as they hear a grinding sound of metal, getting louder and louder.

And, from inside the gate, comes... A tank.

Elise immediately glances at us.

"He has a tank in his house!?"

Well, you asked for action. And those IT billionaires always have shady contracts with the military, so...

The tank moves forward. Elise's old self can't help but get concerned.

Cecilia, well, not so much.

"Now that's cool. Bring it on!"

Without warning, it shoots. Both girls instinctively craw by the ear-splitting noise, the shell barely missing them and hitting a nearby hill.

Cecilia stands up first. And her eyes widen, glowing with excitement.

"Oh, I have an idea"

Before the tank could aim again, our redhead dashes towards it and jumps several meters/feet high, the remaining rags of the lower sheet flying off of her hips as she floats majestically in the air before landing heavily on top of it, fully and deliciously naked.

With a swift movement, she mounts the cannon.

"Let's see if you're really that sturdy"

She groans as her massive thighs begin to press the metal cylinder, the quad muscles bulging obscenely, throbbing with power. Her eyes spark with arousal as she begins to feel the thick metal giving way, crushing inwards.

"Fuuuuuck, this feels so goooood"

Wild with desire, she starts rubbing her soaked pussy against the metal pipe.

Gripping the cannon, her delicate fingers sink into the metal, squeezing it as she grinds her sex faster, purring with sexual bliss, every muscle in her body pulsating with lust. Her monumental body shudders, shaking the entire tank as she cries with a thunderous power-driven orgasm.

Panting passionately, she dismounts, the mangled cannon left with the shape of her slender hands and humungous quads.

Everybody around is frozen in place, the mercenaries' lower parts responding to the magnificent spectacle with uncontrollable boners.

Cecilia knows it. Quickly collecting herself, she glances hungrily at the men.

Elise gets it right away. She takes a deep breath to summon her rational side and shouts, her sweet voice sounding more imposing than they are expecting.

"Get out of here, all of you! NOW!"

Like scared kids, they run away. The two man inside the tank are the last to flee, tripping their way out of the walls.

Cecilia is disappointed.

"Awww"

"No "aw", Ceci. Let's go"

Entering the mansion, they spot a bookshelf in the living room completely out of place, stairs leading down beside it. They glance at each other.

"Geez, is it really going to be that obvious?"

"I think so. Guess the story must move on"

Going down the stairs, they find a bunker, the entrance sealed by a big metal door.

Elise steps forward.

"It looks really heavy"

"I'm pretty sure you can handle it, girl. And I'll help"

"I... Don't know..."

Grinning, Cecilia calmly seizes on Elise's distraction; she discreetly knees and, from under the lower sheet, she grabs Elise's butt.

Elise jumps.

"What are you doing!?"

Without answering, Cecilia fondles the buttocks, round, soft yet firm, feeling a shiver of need coming from Elise.

"You're supposed to... Ah!... Help"

"I am helping"

Her naughty hand slides between Elise's thighs and finds her burning sex, her middle finger delicately touching her swollen clit.

A tiny moan escapes Elise's mouth as her whole body tenses, her rational side vanishing in a snap.

Cecilia ravels in it.

"My goodness, girl, you're almost dripping"

As she flicks Elise's love button, the brunette involuntarily slaps the bunker door in front of her. The impact is so strong that the whole room trembles, the metal bending slightly.

"It's not healthy to keep all this steam inside you, you know"

She deliberately retreats her hand and watches with mischievous satisfaction Elise arching her hips towards her, silently begging for more.

Cecilia licks her lips before burying her face in Elise's butt, avidly sucking her pussy.

A second slap dents the metal door even more, concrete dust falling from the ceiling as the entire structure of the mansion shakes. Elise writhes with lust, running her hands through the goosebumped surface of her breasts, then gripping and pressing Cecilia's head even further towards herself, a tremendous orgasm building up deep in her core. Feeling the delicious urge of her cute friend clutching her hair, Cecilia goes full throttle, her tongue swirling frantically around Elise's rigid clit, picking up the pace more and more until she senses the marvelous point of no return.

Screaming with joy, Elise agonizes in a violent climax, filling Cecilia's mouth with her love juices, the intensity of her release making her slap the door with both hands. The impact is so powerful that the whole wall crumbles, metal and concrete all collapsing into the bunker.

As the dust and debris settle down, our amazons distinguish a large room stocked with food and medicine, laptops, desktops and several monitors showing news programs, stock exchange charts and videos from the tons of security cameras of the mansion.

And a skinny, white guy wearing monochromatic sweaters, glasses and earphones. Brandon Balthazar.

On the other and much better perspective, Brandon, standing behind his desk, holds his breath as the dust fog dissipates. He was following the ordeal on the cameras and knew what was coming to him, but seeing it live is entirely different.

He first identifies the brunette, unfathomably sexy and muscular, still carrying a lovely post-cumming dreamy expression. When she notices him staring at her, she flushes, adjusting the upper sheet to try to cover her massive jugs better.

Then, from behind her, the redhead rises, naked, even bigger and bustier.

"Another successful plan. I'm getting good at this"

And steps in through the enormous hole in the wall. Elise, still embarrassed, comes in next.

Brandon watches expressionless their entrance.

"All right, the wonder girls arrived, as expected"

Adjusts the glasses on his nose.

"Well, I believe I have to thank you"

The girls gaze at each other, then back to him.

"For what?"

"For proving that the time and money I'm spending on this is not being in vain. So..."

"So?"

"Thank you. You can leave now"

Cecilia frowns.

"Really?"

"Yes, I have other things I need to take care of. There's not enough people sleeping in front of the stores for the release of the next WePhone"

"That's... So cringe"

Elise steps closer.

"We're not leaving"

"Well, in this case, also expected, I'll have to, uh, get rid of you"

Our girls have incredulous faces.

"Are you serious? Weren't you looking at the security cameras?"

"Of course I was. That's why I won't take any chances"

He opens a drawer on his desk and takes...

"Yes, a Magnum! A weapon that a single bullet is inexplicably 50 times stronger than a sniper shot, or a grenade, according to video game logics"

Elise raises an eyebrow.

"But, uh, we are not on a video game"

Brandon halts for a second.

"It doesn't matter. I'm rich, I make the rules"

Points the Magnum at Cecilia.

"It was actually nice to see you live"

And shoots.

Just like in video games, the result is rough. So rough that Cecilia almost budges.

Hitting one of her tits, the bullet ricochets, flipping in the air and falling on the expensive Persian carpet under their feet. The immense soft globe bounces, clashing on her other boob, both gently bouncing until they come to a rest.

"Ouch. That actually hurt a little"

Her nipples instantly get hard, then begin to vibrate like a tuning fork.

Cecilia gasps with anticipation, knowing what has just been ignited.

"Oooh, that was the last bit of stimulus that I needed"

Overcome by the sensation quickly emerging, her eyes lock on Brandon's.

"Don't you wanna shoot some more?"

Her voice brimming with desire.

"Please?"

Taking slow, sensuous steps, she walks towards him.

Surprised and with his IQ severely affected by her impressive sight, Brandon fires again, and again. With every shot, the redhead's body trembles more, the serum still coursing on her bloodstream starting to react.

She's midway to his desk when a click indicates that the Magnum is empty.

"No more bullets?" Don't worry, hmmmmm..."

Her veins bulge, crawling and pulsating all over her silky skin.

"This amount is enough. Oh yesssss..."

A fierce wave of pleasure washes her as her muscles begin to fill with even more mass. She coos with delight, the dense sound of her body expanding filling the bunker, her chest broadening wider than a wardrobe, accentuating her hourglass curves, the traps elevating past her neck like mountains resting on top of her shoulders, large and ripped like pumpkins, her arms gaining more and more girth, the enormous orbs of her biceps throbbing and expanding along with her protruding triceps.

Her eyes glow with the awareness of her own gigantic power as she realizes that she's fully in charge; she keeps walking as her growth continues, not even the extreme transformation being able to slow her down, only giving her more and more mind-blowing sexual bliss. With each step, she gets taller, her ultra-sensitive melons ballooning majestically, almost the size of beach balls, her thighs enlarging so thick that barely anyone can wrap their arms around them anymore, her dainty feet hitting the carpeted floor with booming thuds. She briefly closes her eyes and whispers, savoring the otherworldly power erupting inside her, her voice casual but with an arousing hint of dominance.

"Hmmmmm, sooooo much MASS"

Brandon's eyebrows raise as she gets closer, towering higher and higher until she's right in front of him. She moans softly as the spurt finishes, her 2.29m (7 feet 6) voluptuous and colossal figure looming over him like a divine being next to a bug.

"Bad, bad Brandon"

Grabs and raises him by his sweater.

"It was very mean to try to get rid of us. You're lucky that we are cool girls, so you don't have to worry if, of course, you tell where Edmond is. And don't even try to say you don't know who I'm talking about"

"There's a ZCorp facility. Not known to the public. The serum is prepared there. He's there"

And gives the location.

Cecilia opens a proud smile, then notices something. Still holding Brandon in the air, he's invariably in contact with her humungous freckled breasts, more specifically his crotch. She feels his cock twitching in his pants.

"Look at this naughty billionaire. Can't help but enjoy the situation, huh?"

She flexes her free arm, the mountainous bicep doubling its size, bigger than his head.

"Guess I have to thank you too"

And she feels the jerks of Brandon's dick against her jugs as he cums.

Winks at the thrashed billionaire.

"Pleasure doing business with you"

Toss him on his desk. Turns to Elise.

"So?"

"So. Secret facility, huh?"

"Yeah. Not much inspired for this one either"

Well, I'm trying to focus on the spicy passages that the audience enjoys so much. And that you two enjoy as well, for that matter.

The girls gaze at each other.

"Yeah, he's right"

Elise faces the destroyed exit of the bunker.

"All right. Next stop, secret facility"

Wookey
