Andrea guided the bar up to Stewart's throat, "Tell us now, or we'll crush your throat!"

"Okay ... okay," Stewart managed to squeak out, "Just let me breathe!"  The girls eased up the tension on the bar and Stewart spilled everything about the magic pills and the effect on him.  "And now I'm the one that big and strong ... and I can make ... others ..." his voice trailed off as he realized that he had said too much.

Andrea returned the pressure to his throat, "What do you mean, you mean without the pills?  How?  Answer!!"

"I slept ... with Tiffany ..."

"Tiffany?"

"Oh gross!"

"Woof! what a dog!"

"You wouldn't say that if you saw her today.  She's huge! And strong!  Just from ..."

"From what, Stewart?" Andrea asked, inching the bar closer to his neck.

"My ... you know ... my semen."

The girls stood in stunned silence.

"He's got magic ... cum?"

"What if he's lying?"

"Yeah maybe he just wants to get off..."

"No, he's too much of a baby to try to lie just to save his neck."

"We gotta drink ... it?"

Then the shy girl spoke up, "I'll give it a try."

They all looked at her.  Andrea said, "Are you sure Ginny?"

Ginny stood up and walked over to the bench.  She was just under 6 feet tall, gangly, with pipe cleaner arms and legs that seemed to stick out all over. "Sure, I mean my boyfriend back at my old school was kinda into that thing, you know?  It doesn't taste too bad..."

After lifting the weight back up with the help of Stewart and the other two girls, Andrea ordered the girls to get some jump ropes and tie Stewart hands and feet so he couldn't move.  Then she found some scissors in the next room that was used as a sewing room and she cut away Stewart's tight shorts, exposing his relaxed dick.  Stewart was protesting all the while and trying to think of computer code to keep his mind off of what they were doing.  Although he was a lot stronger than before, he was still no match for the ropes.

"Alright, Ginny, go for it."

Ginny gingerly knelt in front of Stewart and started gently rubbing this cock.  Then she proceeded to taking it her mouth and sucking it.  Sure enough, try as he might to not give in, Stewart's magnificent manhood began filling with blood.  Higher and higher it rose as Ginny hastened her pace, sucking and rubbing it.  The other girls were astounded at it's growing size.

"Way to go Ginny!"

"You go girl!"

"Holy shit!  Look at the size of that thing!" [As mentioned in part 3 of this epic, I have tried to affect the distinct language of the Southern California teenager.  For more about this, consult the definitive work on this topic, Dialects of Teenagers - Origins and Pronunciations, by Walter Heisenbacher- Mac] [Okay, I'm just kidding- don't go running to your local library looking for the book, I made it up - Mac, again]

Ginny was shocked at the mammoth cock she was working on.  Her boyfriend was only half this size.  But she continued working it harder and harder.  Soon it was all she could do to fit its hot, throbbing tip in her mouth.  She licked the shaft and wrapped her slender fingers around it, urging it to come forth with its magic jism.

Stewart was trying to fight the overwhelming feelings that were racking his body, but all he could think about was how good it felt, and how much he wanted to explode in the young girl's mouth.  He tried to think of computer programs but his mind kept designing a program to create supergirls.  Finally, he could hold back no longer.  His entire body quivered and strained and then finally let loose a torrent of super cum.

Ginny knew that he was about to blow.  She braced herself and got ready to swallow.  One more suck on the tip and he started to shake.  Then he started to cum.  And he came and came.  It seemed to Ginny like he would never stop.  It tasted so strange, but so good, that she greedily swallowed every drop that he offered.  Finally it was over.

Ginny stood up and wiped the remains of the sticky liquid from the sides of her mouth.  The girls watched intently for any changes.  A minute passed, and then two.  Andrea was just about to start the torture again to get the truth from Stewart when she noticed something happening to her friend.

Ginny felt a little dizzy as a warmth spread through her lanky frame.  Then suddenly, her tits, which had previously been little more than nipples pushing against her tight top, began to push outward on the stretchy material.  Soon her thin arms and legs began to fill in with toned muscles like a fitness competition.

But the growth kept up.  Her breasts now stretched the top so tightly that they were being held flat against her expanding chest muscles.  Her arms were swelling with hard muscle and her legs started showing definition in her quads.  Then her butt, which was pretty much flat before, began growing and rounding and her calves blossomed into hard diamonds of muscle.

Ginny held up one arm and flexed it hard.  To her surprise a bicep the size of a lemon popped up out of her formerly shapeless arm.  She reached out with her other hand to see if it was for real.  As she felt her arm, her muscle seemed like it was made of rock, it was so hard and solid.  The other girls gathered around her, ignoring Stewart.  They touched her muscles and tried to squeeze them.  Terri grabbed a hand and tried to pull it down.  Ginny just grinned and held it motionless.  Then Terri put all her weight on the arm, even lifting her feet off the ground.   Again, Ginny didn't move an inch.  But a couple of seams in her sleeve popped open as her bicep swelled even larger.

"Geez Ginny!  How strong are you?" an incredulous Debbie asked.

"I don't know," Ginny shrugged her wide shoulders, "Let's find out."  With that she walked over to where the bar was racked. It still held 300 pounds.  Without thinking, she grabbed the bar and lifted it easily to her bulging breasts.  Her biceps finally pushed the fabric of her top too far and the sleeves ripped open exposing the largest arms these girls had ever seen on a girl.  Andrea ran back to the sewing room to get a tape measure while Ginny transferred the bar to her left hand.  With steady, controlled motions, she curled the heavy bar five times then switched hands for another five reps.

"Wow! That was easier than I thought it would be!" Ginny gushed as she returned the bar to its rack. "And you could only do twelve bench presses, Stewart.  I bet I could bench that all day!"  She held her pumped up arms and proudly displayed her big biceps while Andrea wrapped the tape measure around one.

"Check it out girls, Ginny's got guns! 13 inchers!" Andrea called out.

Then Ginny started pulling at the neck of her T-shirt, "But I gotta tell ya, this shirt is just too small now!"  With that she tore open her shirt like she was ripping a piece of paper.  Released from their bondage, her newly developed breasts poured out, bouncing in front of her until the came to rest on her powerful chest.

The sight of Ginny's boobs exploding out of her shirt was too much for Stewart. His hard on returned with a vengeance.  Seeing the stiffened member, Terri knelt down quickly and grabbed it with both hands.

"My turn, now." she said as she tried to duplicate Ginny's actions.  After a few tries, she got into the rhythm of it and stroked Stewart closer and closer to the edge.

"Stop!" Stewart protested, "Wait ... stop ... you ... don't know ..."

"Shut up Stewart," Andrea commanded, "Or I'll stuff a gym sock in your mouth."

"No ... help ... gotta ... stop"

"That's it!" Andrea found an old sock and forced it into Stewart's mouth. "Go on Terri."

Terri resumed her stroking and licking. She sucked the big red tip and nibbled on it, too.  Soon Stewart was ready to climax again.  How many times is this? he asked himself before he lost himself to the immense pleasure rocketing through his body.  When he came, Terri made sure to swallow all of it.

While Terri was waiting for the changes to start, Andrea straddled Stewart's legs and gently grabbed his big cock. "My turn." she said looking him in the eye.  He looked back with a shocked expression and tried to scream out a protest. But the socked was lodged too firmly in place and all it came out as was a muffled cry.  He lay his head back in resignation.

"You're gonna blow your own brother?" asked Debbie.

"Sure ... why not.  Besides, he's just my step-brother." Andrea said as she lowered herself closer to the already hardening rod.  She sucked him like an expert.  Slow and gentle at first, then harder and firmer.

Even though he was repulsed by the idea of his cock being sucked by his step-sister, she was so good at it that he couldn't resist getting turned on.  Suddenly he was rock hard again and felt a power surge all through his body.  He was huge, powerful as an ox, a superman!  The pleasure raced through him and he rocked and bucked in time with Andrea's deft hands and mouth.  Then, explosions went off in his head and groin as he released another torrent of jism, pumping it out, spurt after spurt.  His whole body tensed for one final second then went limp again on the bench.

As Andrea stepped back, wiping her mouth, she noticed that Terri seemed to be shrinking.  It looked like her outer layer of fat was just melting away.  But then it seemed as if all those fat cells suddenly concentrated in her boobs as they stretched further and further outward. Then her muscles started growing, and growing.  She was wearing a loose tank top over her pink sports bra, but the bra was having trouble containing her new size.  Her sweatpants, now four sizes too big, slipped down her legs showing off her bulging quads.  She stood there in just her panties flexing and re-flexing her legs.  Although Terri's muscles were probably no larger than Ginny's, because of her 5' 6" size, she looked huge.

Terri went to take her turn with the bar. As she lifted it neatly with one hand she saw that Andrea was beginning her growth spurt, too, and Debbie was tentatively kneeling down in front of Stewart.

"What's wrong Deb?" asked Terri as she lazily curled the massive weight, "Don't you want to be strong, too?  Look at this!" She held her rock solid arm up and flexed her thick bicep.  "And check out these abs." she said as she lifted her tank top.  The material of her bra had taken just about all it could and it was starting to rip at the top.

"Yeah, I guess" she paused for a second, playing with Stewart's relaxed dick, "It's just ... should we be using Stewart like this?  Just for our own growth?" Then she smiled wickedly and winked,  "I mean hell, let's share the wealth with more of our friends!"

"Right on!"

"Yeah, we could help like dozens of girls at school."

Then Debbie wrapped her beautiful lips around Stewart's quickly swelling monster of a cock and got down to business.  It began responding instantly to her ministrations and soon reached its magnificent fullness.  Debbie was impressed.  She had seen pictures of penises this size and once saw a movie with a guy this big, but she had never held on in her hands and mouth before.  She decided that she wanted to enjoy this as long as she could.

Just when Stewart was about to cum and his body was tensing up, Debbie slowed down and then lifted her head to watch Terri flexing her new muscle for the other girls.  She continued to stroke the underside of the towering cock, just enough to keep it hard but not enough to allow release.

Andrea and Debbie often dressed alike and today was no different.  They were both wearing oversized sweatshirts and tight aerobic leotards underneath with some loose shorts.  Debbie watched as Andrea stripped off the sweatshirt.  Her tits were filling out the leotard to the point of ripping.  Then her muscles stated growing.  Her arms filled with balls of powerful muscle and her legs kept getting larger and larger.  Debbie returned her attention to Stewart flagging pole, just in time to keep it rock hard and throbbing in pleasure.

Again and again Debbie would bring Stewart to the edge of release then slow him down.  This caused Stewart's erection to grow even harder, screaming for creaming.  Stewart was beyond comprehension.  All his mind could think of was cumming.  His entire body was wracked with the intense sensations and he bucked and arched his back trying to get off.

Finally, Debbie was ready and pushed the monstrous organ over the edge.  Explosions were going off everywhere in Stewart as he let go with everything he had. Debbie did her best to keep up with the deluge.  Just when she thought he was done another stream of warm, sweet tasting cream would spurt forth.  This went on for at least a minute, Stewart jetting forth his magic cum, and Debbie greedily gulping it all down.  In the end, Stewart was totally spent and he collapsed back on the weight bench.

Debbie rose from her knees in time to see Andrea lifting the bar with her right hand.  Her muscles looked huge and beautiful.  She had just walked over to touch the newly formed muscle when she felt an intense wave of warmth rush over her.  She stopped and pulled off her sweatshirt seeking some cool air.  She stared down at her arms as she felt a tingle pass from her fingertips to her shoulders then across her chest.  Then it started in her toes and went up to her vagina, thrilling her momentarily.  She closed her eyes to take in the sensation,

When she opened her eyes again, the other girls were staring at her, specifically her chest.  She looked down and saw the two most perfect breasts protruding from her chest.  But they were still growing.  Past a C-cup and well into a D-cup, these puppies were expanding quickly.  They were extremely heavy and started to weigh her down.  But then she felt a tingle run across her back and her back muscles started growing.  In seconds the stress of her tits was removed and she stood up straight and tall.  As a matter of fact, she thought to herself, they almost seem weightless.

Then Debbie saw the muscles in her forearms begin to writhe and swell.  And then her biceps and triceps.  Everywhere she looked on her body, there seemed to be inches and inches of muscle being added by magic.  She could feel power coursing through every cell of her magnificent body.

Debbie looked at herself in the mirror just in time to see her chest and tits rip through her hopelessly outsized leotard.  The material fell away leaving Debbie naked from the waist up.  The image that greeted her was some kind of combination porn star and Ms. Olympic.  Indeed all of the girls could easily go toe to toe with the best lightweight female bodybuilders.  But Debbie had a lot more up front than the others, including Terri.

Stewart realized somewhere in his darkening mind, that she had turned out just as he had imagined her.  He smiled as he gazed on her reflection in the mirror, then he finally passed out.

------

Stewart was slowly waking up from his own dream-filled sleep with a familiar feeling in his groin.  He just dreamed that he had come again for the umpteenth time.  As he wearily opened his eyes he realized that he was still tied to the weight bench, exactly where his sister and her friends had left him.  At least that awful tasting sock was out of his mouth, although the taste still lingered.

As he came to his senses, Stewart felt someone's fingers playing with his cock again.  He realized that he hadn't been dreaming.  He raised his head as far as he could and saw a head of blond hair between his bound legs.  As his eyes focused, his shock turned into horror and embarrassment as he recognized the face coyly smiling back at him.  "C ...  Carol?"

Stewart's step-mother continued fingering his limp cock as she kissed it and licked it, obviously trying to bring it back to it's glorious hardness.  There was something different about how she looked today.  Carol was at least forty years old with a touch of gray hair and more than a few wrinkles around her eyes.  But now she looked young, Stewart guessed about mid-twenties, with tight, smooth skin and wild, blonde hair.

"Oh, you're finally awake?  Have a good nap?"  She placed her mouth over the tip of his rod and sucked gently on it.  As usual, it didn't take a whole lot to get it going and soon the limp member was beginning to stiffen again.

"What's going on?  Wh ...  What are you doing?"

[hatour]

"Wow," Carol said as she lightly stroked his lengthening shaft, "You know, Stewart, I'm really impressed.  I've seen some really big cocks in my day, but yours ...  well, yours is just amazing!"  The massive cock responded by abruptly rising like a balloon being blown up.  "You see, I found some pills you had in your pockets as I was getting ready to do the laundry this morning.  And then I heard the commotion down here, so I peaked in to see what was going on.  I figured that the pills I found must be the same ones you talked about and then I saw what happened to Andrea and her friends.  So I took your magic pills after the girls left.  You can't believe how it felt!  Suddenly I wasn't just a skinny middle aged woman any more.  I felt like a superwoman!"

By this time, Stewart's pole was fully extended and throbbing with every pulse of blood.  "So I came down here to see if I could lift that bar like the girls did.  That's when I saw you lying there and I got a wild idea.  I wondered if I could get even stronger if you came inside me.  So I beat you off and guess what?  It worked!  My strength must have doubled because I was able to lift that bar with just one hand, and it was easy, too."

Carol paused for a second while a wave of warmth swept over her body.  Stewart, still too dumbfounded to speak could have swore that he saw her muscles growing.  His eyes widened in terror as he realized what was happening.  "How ...  how many ..."

"How many times?" Carol smiled as she felt the surge of power pass through her, "That was number two." She stood up revealing the extent of her magical growth.  She was short, only about 5' 5", but Stewart could see that her physique was becoming quite literally packed with muscle.  She swung one thick thigh over the fettered boy, and straddled Stewart's mid-section.  "I think I'll try something different this time.  You just can't imagine how good it feels to be this strong, this powerful.  After your father died, I thought I didn't have much of a life anymore ...  but now, now I think I'll live a little.  And now I have the power to take what I want, take who I want.  And right now, I want more!"

Carol was wearing the cotton blouse that she usually wore when she worked around the house.  She also had on a short skirt and tennis shoes.  She reached down and effortlessly tore her underwear off, exposing her blond bush.  Stewart threw his head back and stared at the ceiling, embarrassed at looking at his step-mother's crotch.  Carol slowly eased herself down over Stewart's raging hard-on.

"Remember this shirt, Stewart?  Remember how my skinny arms seemed almost lost in the sleeves and how loose it fit around my tiny chest?  Well look at it now, Stewart.  C'mon, look at me, Stew." Carol commanded as she began to slowly ride Stewart's rock hard cock.

As Stewart looked down from the ceiling, Carol flexed her arms and chest.  Her lats stretched the sides out while her biceps completely filled the sleeves.  Her chest was threatening to pop a button off of the front.  As she expected, the sight of her bulging muscles made Stewart even harder than before.  She, too, had seen the pictures that Stewart had downloaded onto his computer and the magazines and comics he tried to hide in the closet.  She knew that hugely muscular women turned him on, and she intended to use that to her advantage until she got as much power from him as she could.

Carol leaned forward and held onto the bar above Stewart's head, nearly brushing her bulging boobs against his nose.  "I know that you like big, buff women, Stewart.  Let's see how big and strong you can make me, okay?  Let's see you fill me with huge, hard muscles." She began to slowly ride the huge cock.  She increased the tempo of her rhythmic humping.  "C'mon Stewart, make me stronger, baby, you can do it, fill me with muscles Stewart, with power, make me bigger baby, bigger, harder, stronger, oh yes, big muscles, c'mon Stewart, you know you want to, make me huge, stronger, you can do it, you can do it, HUGE ...  STRONG ...  MUSCLES ...  BIGGER ...  BIGGER!!" Carol was shouting, commanding.  Stewart was wildly bucking, lost in her suggestive images, wanting only release, wanting to make Carol into the perfect woman, his perfect woman, trying to will her muscles to explode, her breasts to balloon out.

Then suddenly he came.  And he came.  It was like the first time he had ever masturbated, except even more intense.  Carol's tight pussy caught all that Stewart gave her and held it inside until it became a part of her.  She placed her hands on Stewart's heaving chest and waited.  Soon she felt the familiar warmth.

Carol sat upright and turned her head slightly with her eyes barely closed as if she were listening for something.  "Wait for it ..." she paused, then she raised her arms and suddenly flexed them larger than ever, "Yessss!!!"

Her biceps tore through the cotton sleeves like twin volcanoes erupting out of the sea.  Her boobs burst through the front of the blouse sending buttons flying across the room.  Her lats spread out so wide that they forced the blouse outward revealing the fullest tits and tiniest waist that Stewart had seen.  The sight of her dramatic growth was too much for the young man.  He was so utterly turned on by her power and size that his cock snapped back to attention and spurted another full load into Carol's hungry box.

"Ohhh ...  Thanks, Stewart, I'll take that as a compliment that you like my new physique.  And that'll add to my growing power, too.  But maybe I should give you a break now, we can pick up where we left off this afternoon."

"I don't think so, bitch!"

Carol and Stewart both looked in the direction of the voice, both surprised to see that it was Tiffany standing on the steps to the basement.  She was wearing a tank top with no bra underneath - not that she needed one - and a pair of short jogging shorts.  Stewart saw that she was flexing her huge quads.  In another instant, Tiffany was flying across the small room toward Carol, propelled by her powerful legs.  She caught Carol off-guard as she flew towards her.  Grabbing the older woman around the shoulders, she flipped over her, pulling her off her prone boyfriend.  Carol was sent flying across the basement herself by the force of the young girl's attack, only to be stopped by the far wall.

Meanwhile, Tiffany jumped back to her feet and raced back to her lover, tied to the weight bench.  "Oh Stewart," she gasped as she easily ripped the rope, freeing his left hand, "are you okay?  What has she done to you?"

"I ...  I'm okay, Tiff, but I need to tell you ..."

He cut his sentence short as he looked up in horror.  Carol was already up and flying at the girl with her mighty fists balled and ready for action.  She had recovered immediately, surprised that the attack and the smash against the wall had not hurt at all.  Emboldened by her discovery, she launched herself at Tiffany.

Tiffany had just spun around when she was met by a crushing blow that knocked her over the weight bench and across the floor.  She was more stunned that hurt and Carol took advantage of her hesitation.  In a flash she was on top of the girl and lifting her off the floor by her shirt like she was a rag doll.  Carol held her up with one hand and smashed her across the face with the back of her other hand.  The force of the blow was so great that the girl went flying backwards six feet while Carol was left holding the remains of her tank top.

While this quick battle was going on, Stewart was struggling to free his other hand.  He could just barely reach the rope.  Frantically he worked the knot hoping that he might be able to help his girlfriend, all the while cognizant of the fact that Tiffany's and his strength combined couldn't match Carol.  Still, he had to try.  Just as he freed his other hand, Tiffany's body came crashing down on top of him.  The poor girl was all but unconscious from the beating she was receiving at the hands of Stewart's step-mother.

Carol stepped casually towards the couple, removing her skirt with a quick tug of her powerful hands and exposing her massive thighs completely.  She lifted the semi-conscious girl above her head, then settled her across her wide shoulders.  Her giant biceps bulged ominously as she bent the girl's frame backwards with one strong hand holding her shoulders and the other holding her thighs.  Tiffany gave a soft cry of pain as she felt herself bending to the strong woman's might.

Carol stepped over the prone boy and squeezed his middle with her thick legs, swollen with rock hard muscle.  "Fuck this shit, I'm gonna ride you til your dry, boy," she said as she settled down on top of his flaccid penis, "so get it up or I'll cut you in half with my legs.  C'mon Stewart, you know what to do."  She began roughly rubbing his cock with her pussy, arousing the sleeping giant.

Stewart responded by pushing at Carol's thighs with his now free hands.  He was met by mounds of pumped up muscle.  His fingers traced the deep clefts and high ridges of her quads.  He realized that he was getting turned on partly out of lust for her incredible muscles, but also out of fear that these perfect legs could cut him in two with even trying hard.  His cock began stiffening again, as if it were drawn to the object of his lust.  Stewart's hands continued up Carol's legs and wrapped around her tiny waist.  Then he cupped her hard, round ass in his hands and helped her pump him into her hungry snatch.  His hands continued up to her abs and felt the marvelous muscles ripple and bulge with her movements.  As his hands reached up to grasp her pendulous breasts, he could hold back no longer.  A jet of magic cum shot out from his engorged member to be quickly absorbed into his step-mother's already super body.  Stewart let his hands drop to the side exhausted and ashamed that he couldn't stop Carol from getting what she wanted, so overcome was he by her fantastic physique.

Moments later, Stewart looked up to see Carol reveling in her latest growth spurt, her arms flexing even larger than before as she increased the pressure on the hapless Tiffany.  The pain from the increased pressure on her back, brought her back to the edge of consciousness, and she cried out for help.

------

Stewart Thompson was nearly crying.  He was exhausted and rubbed raw.  And he was just about to swear off muscular women for the rest of his life.  He had had enough of them.  It's one thing to fantasize about something, it's quite another when your fantasy springs to life and starts abusing you.  This was not what Stewart had wanted at all.  Super women were supposed to be like Tiffany, strong but gentle, loving, protecting, and sexy.  At the current time, none of those adjectives fit his step-mother, who was grinding away at his crotch trying to excite him one more time.

[hatour]

"More, Stewart, I want more!"

Stewart had lost track of how many times he had come inside Carol, let alone how many times he had come this morning.  Was it still morning?  Pleasure and pain swept over him like ocean waves, rising and falling, seemingly never ending.  No, he needed to focus his mind, try to think of something else, not get lost in the arousal stirring in his loins.  He thought about his computer, mentally running down the intricate maze of circuit boards until he found the precise logic chip.  He placed an icon of his huge cock on the logic chip.  It was either turned on or turned off.  And he meant to keep it turned off no matter what Carol was doing.  Suddenly he felt his member beginning to stiffen again, but just as quickly, he mentally flipped the switch to turn it off again.  Several more times, he thwarted Carol's attempts to drain him of his super juice.  Through a haze, Stewart realized that he was finally in control.

Disgusted that she could get no more from her depleted step-son, Carol swung off him and unceremoniously dropped the unconscious Tiffany to the floor at his feet.  She roughly grabbed the limp member and stroked it, trying to force it to respond.  Stewart resisted again by mentally flipping the switch inside his head to off.  Then Carol tried to gently tease the passive cock and again Stewart frustrated her desires.  Finally, she gave up, thinking that he was truly drained.

Leaving the two limp and lifeless teenagers where they were, Carol rose from her knees and swaggered up to the mirror to see what she looked like now.  She gasped as she first caught her reflection in the mirror.  She was covered from neck to calf with the most outrageous, bulging, mass of muscle that she had ever seen in her life.  She quivered as she tentatively flexed her arm, staring at the impossibly huge mound of muscle rising on top of it.  She ran her other hand over the mountain of feminine power, amazed at the size and hardness.  Then she repeated the process with her other arm.

While Carol continued her intense examination, Tiffany slowly tried to rouse herself.  She had been shaken back to consciousness when she hit the floor, but her entire body ached from the torture she had been through.  She felt like she had been hit by a truck.  Blindly reaching up for support, she grasped Stewart's knee and thigh, and attempted to pull herself up.  Suddenly, she felt Stewart reach down and grab her head with his hands.  He held her face between his legs with her mouth pressed against his limp penis.  Although she struggled to release herself, she was still too weak to break free.  She could smell the combination of cum and sweat on Stewart's cock and instinctively licked at the sweet tasting semen.

As Stewart lay on the bench with his eyes shut, he retraced his mental steps to the logic chip and flipped it on.  Instantly his massive cock sprung to attention filling Tiffany's mouth and throat.  The passive girl was so caught off guard, that she couldn't even get a sound out.  Stewart created another mental switch and flipped it on, too.  Instantly a stream of cum began jetting down his girlfriend's throat.  Without realizing what she was doing, Tiffany swallowed as fast as she could to keep from choking.  The stream of cum continued, on and on, for what seemed like an eternity to Tiffany.

Stewart was imagining his girlfriend growing stronger and stronger, but still remaining the same size as she was when he left her that morning.  He thought of her awesome muscles being touched by the moonlight as she flexed them just for him.  He loved her at just that size.  But he knew she would have to be a lot stronger to face Carol again.  He poured every ounce of emotion and love that he could muster into his magic seed, willing that it keep pumping into Tiffany until she had had at least eight full loads.

Finally the deluge ended as quickly as it had started.  Stewart mentally retracted his magnificent pole and released Tiffany's head, lightly touching her cheek as he dropped his hands again.  Tiffany slowly raised her head with her eyes closed, resting her hands on Stewart's thighs.  Somehow, their minds had connected and Tiffany shared Stewart's vision of her power.  She paused for a while, holding on to the image in her mind.

Moments later, Stewart felt a flush of warmth on top of his thighs.  He opened his eyes to see Tiffany smiling down on him with a strange glow on her face.  Oh!  he thought in his drowsy state, so that's what a goddess looks like.  Tiffany slowly rose from where Carol had so roughly deposited her.  Although her muscles didn't look appreciably larger, they had a rock hard definition about them that surprised Stewart.  He watched as she casually stepped toward the still flexing step-mother.  Her every movement caused dozens of muscles to bunch and flex and then relax again in what looked to Stewart to be a symphony of grace and power.

Any pain that Tiffany had felt, seemed to fade away as the nearly overpowering warmth washed over her.  She felt so good, so powerful, every movement seemed effortless.  She approached Carol who was so infatuated with her new physique that she was oblivious to what was transpiring on the other side of the basement.  As Tiffany walked up, Carol was flexing her four inch thick pecs.  Her now firm tit flesh jiggled slightly as it came to rest on top of her beefy slabs of muscle while deep striations stood out in her cleavage.  Tiffany calmly reached out and grasped her shoulder with one hand.  With a flip of her wrist and arm, she sent the shocked supermom flying across the basement.  Carol smashed against the concrete wall, still stunned by the unexpected attack.

Carol shook her head to get her senses back, "So the little bimbo hasn't had enough after all."  She stood and brushed the concrete dust off her now perfect ass, "Guess I'll have to finish the job this time."  She flew at Tiffany with her mighty arm cocked and fists balled.  She threw everything she had into one big knock out punch aimed at the young girl's chin, fully expecting to nearly rip her head off with the blow.  Instead, Tiffany's head moved only and inch or so and Carol dropped to her knees holding her hand in pain.

Tiffany grabbed her opponent's wild blond hair and picked her up off the floor, "Was that your best shot, Carol?  'Fraid you'll have to do better than that this time.""

Seizing the opportunity for another open shot, Carol fired her other hand into Tiffany's exposed midsection.  It felt to Carol like she was hitting a rock wall, though, and she recoiled in pain again.  Tiffany continued to hold Carol at arms length by the hair, even though she now weighed well over two hundred pounds of solid muscle.  She delivered a series of slaps to Carol's face that sounded like baseball bats breaking.  Then she planted her fist deep into Carol's relaxed stomach, doubling the older woman over.  Tiffany then delivered a vicious upper cut to Carol's jaw that sent her flying across the room once more, this time cracking the cement wall slightly.

Carol braced herself against the wall as Tiffany approached her.  As the taller girl came near, Carol collapsed into her arms.  Then suddenly she held onto Tiffany's shoulders as she brought her knee up between the girl's legs as hard and quickly as she could.  But Tiffany moved quickly, too, and grabbed onto Carol's leg, holding it tightly against her clit.  Carol struggled to free her leg, but Tiffany's grip was too tight.

The young girl looked into Carol's eyes and sensuously licked her lips as she began forcibly rubbing her thigh against her sex.  The thick cords of muscle added unbelievable stimulation and Tiffany increased her grip.  She couldn't believe how good it felt to feel another woman's super muscles against her moistening lips.  She closed her eyes and reveled in the sensations, lost in a fantasy of being taken by this incredibly muscular and sexy woman.

But Carol wasn't sharing the same fantasy.  She was repulsed by the girl's actions.  In desperation, she grabbed Tiffany's generous boobs, noticing to her amazement that they were so large that she could barely cover half of them in her hands.  She squeezed and twisted them mercilessly.  But instead of hurting this girl of steel, this just seemed to add to her pleasure.  Tiffany's breathing increased until she was taking short gasps as all of her muscles tightened.  Carol couldn't believe it!  The young fool was having an orgasm in the middle of a fight!

As Tiffany's movements shuddered to a halt and her grip relaxed, Carol took advantage of the opening.  She brought her hands down on the girl's shoulders as hard as she could, stunning her and driving her to her knees.  Carol grabbed Tiffany's hair and pulled her head down as she brought her knee up, spinning the dazed girl around.  Then she wrapped her thick python around her neck and began to apply a deadly choke hold.  Carol's bicep swelled larger than even she could believe as she applied undreamed of pressure to the hapless girl's throat.

Just as Tiffany's body was beginning to go limp from lack of oxygen, Carol felt a pair of wonderfully large breasts press against her back while two thick arms surrounded her and two powerful hands held her wrists.  She looked up to see a pair of arms that dwarfed even her huge guns begin to slowly, inexorably, pull her hands away from the girl's throat.  Carol resisted with every fiber of strength she had, but it seemed to make no difference whatsoever.  As unbelievably strong as she was, she was still powerless to stop whoever it was who had her.  As she was forced to release Tiffany, another super muscular woman stepped up and scooped up the girl.

Mary and Rita had arrived moments before, and finding the door open, came in to look for Stewart.  Just then the fight had started in the basement and the sound of combat drew them downstairs.  Stewart had finally managed to untie the rope binding his ankles during the fight and was about to try to stop Carol from killing Tiffany when Mary and Rita entered.  He was ever so glad to see these two powerhouses walk down the stairs.  Now Mary wrapped her massive leg around Carol's legs, essentially immobilizing her, while Rita tended to the gasping Tiffany.  Her nose was bleeding and looked to be broken.  Carol was fuming.

"Who the hell are you!  What are you doing in my house?" Carol demanded as she struggled in vain to free herself.

"You must be Stewart's step-mom," Mary replied calmly, "My name is Mary and I'm the one that started this whole thing.  And now I've got to get this 'thing' under control.  I had the feeling that Stewart might be getting into trouble, but I never expected that I'd have to deal with you."  Mary easily brought Carol's arms together in front of her and held her wrists with one hand while taking her chin with the other.  "Rita, would you bring the vials please?  I don't know you very well yet, Stewart, but you don't strike me as the kind of guy who would willingly let your step-mother fuck you."

Stewart sheepishly shook his head and quickly explained what had happened that morning, including how he started it by trying to show off.

"I kind of thought so." Mary said as she forcibly opened Carol's mouth.  "Two drops from each vial, Rita.  Sorry to have to force this down you ma'am, but it's for your own good."  Mary closed Carol's mouth after Rita dropped the first of the magic drops in and then repeated the procedure for the second drops.  After she was sure that the liquid had gone down, she released the furious woman.  I sure hope that Eunice was right, Mary thought, we've only got one shot to get it right.

The magic worked almost instantly.  Carol fell forwards onto her hands and knees after Mary let her go.  The two friends stood by watching as her body began to shrink.  Stewart knelt next to Tiffany, oblivious to the fact that he was totally naked.  He watched as the woman who had almost killed his girlfriend quickly lost her muscular definition and size.  The process continued for five minutes, finally leaving Carol a shadow of her former self, but much closer to her original size.  She sat on her basement floor sobbing with her head in her hands.

"Oh Stewart," she said, tears streaming down her cheeks, "I'm so sorry ....  so, so sorry ...  can you forgive ...  forgive me?  I don't know ...  what happened ...  I went ...  crazy, I guess ...  I'm sorry."

Stewart stood up and realized he didn't have anything on.  He tried to cover up his over-sized endowment and ran over to the laundry to grab a towel.  Everyone in the room, except for a quickly recovering Tiffany, looked away in embarrassment.  She smiled broadly as she watched his cute buns and wide back.  Stewart came back with a large towel wrapped around his waist and helped his step-mom up off the floor, wrapping another towel around her chest.  Stewart wasn't sure, but it seemed like her breasts were a bit larger than they had been before.  And her hair was still totally blond.  In fact it seemed that she still looked like she was in her late twenties instead of her early forties.

Carol sheepishly took the towel and covered herself with it.  Then Stewart gave her a quick, awkward hug, "It's okay ...  mom ...  I understand."  Then he went back to Tiffany and helped her up.  Thanks to the magic flowing through her body, her nose had already healed and if anything, looked even cuter than before.  Stewart bounced back over to the laundry and rummaged around for a top big enough for Tiffany.

"What about Tiffany?" Rita asked Mary.

Just then, Stewart returned with a T-shirt for his girlfriend, "Wait ...  I ...  she ...  I mean, I gave her the power as a gift.  Isn't that what you intended, Mary?  That this gift should be shared?  She never took anything by force, not like the girls and mom."

"You're right, Stewart," Mary said as she held the vials, "So I'll let you decide, Tiffany, just like I let Rita decide.  One vial decreases your strength and one decreases your size.  What do you think?"

Tiffany pulled the shirt over her big tits as she thought about her options.  She was immensely strong now, so strong that she would have to be really careful no to destroy things, but still, it felt so cool to be so strong.  And she had a killer bod now that she couldn't wait to buy a bikini for and strut her stuff around Mission Bay.  "What happens if I take only one drop of that stuff?"

"I'm just guessing, but I suppose that it only takes you half way back."

"Then let me have one drop of the strength reducer." Tiffany saw Stewart begin to protest, "Stewart, don't worry, I'll still be stronger than a whole platoon of Marines." She smiled and took the magic liquid.  Again, the magic worked immediately.  Tiffany felt a little dizzy, but the feeling passed as quickly as it came.  She still looked the same, but she could tell that she had just lost a sizeable amount of strength.  She walked over to the weight bench and picked the bar up with one hand.  Her 18 inch bicep swelled but she could tell that she really wasn't using much strength at all to curl it.  Satisfied that she was still well within the definition of 'super', she rejoined the others.

"We better get going, Mary," Rita reminded her friend, "It looks like we've got another four girls to catch and deal with still.  Carol," she said turning to her, "any idea where they would have headed?"

"Hmmm, I heard them laughing and talking about going to football practice or maybe a gym?  I'm sorry, they were out the door pretty fast."

"How about if we come along," Stewart suggested, "You might need some help?"

"You're definitely coming with us, just so we can keep an eye on you until your 24 hours are up." Mary said as she poked Stewart in the chest for emphasis, "So hustle your buns and get some clothes on.  And Tiffany?  Yeah, I think we could use some help, especially since we have to round up four of them.  Move it Stewart," Mary yelled up the stairs after him, "We'll meet you in the car!"

Mary, Rita and Tiffany headed out to the car and Stewart came bounding down the stairs moments later, tugging a too tight shirt over his head.

The End
