Part 1

Mark was starting college after the summer break. He'd be moving across several states far away from his parents house and into a very different house. To save money, he'd be moving in with his grandmother who lived not too far from the college. Or at least, that was his excuse for moving there.

For as long as he could remember, he'd always loved and admired his grandmother. He loved her bright and cheery personality. He loved her cooking. And he absolutely loved her huge, bulging muscles.

The day he learned that both his father and his aunt were adopted, it changed his life forever. His love evolved from a more familial one, into a deep, romantic, lustful love.

All his fantasies, his wet dreams even, they all became about her. He specifically chose to go to that college just so he could move in with her. Be closer to her. He didn't even wait to make the move after graduating high school. Not even 3 full days after graduating he was moving out of his childhood bedroom. He couldn't contain his excitement at sharing a house with the most perfect woman he could ever imagine.

He'd managed to pack down his entire life into a few small, but heavy boxes that he loaded into his old banger of a car, before driving it to his new home. His grandma's house.

It was late into the afternoon when he arrived thanks to departing in the early hours of the morning. His grandmother already sent him a key, so he unlocked the door and entered, immediately calling out for her.

It was quiet at first. He never heard a response. But after a few moments, he heard some loud clangs of metal. A familiar sound to Mark from all his years watching workout videos. They were weights. And they sounded heavy. Very heavy.

Mark reminisced on the first time he snuck down to his grandmother's basement gym and watched her workout. It was when he had his first erection, and where his obsession with her muscles began. He'd always like them before that, but after seeing them work, it changed his world.

He moved as quietly as he could and skulked into the basement where old jazz music was playing. And there she was. Wearing an old polka dot dress that looked ready to burst. Her silver hair with a hint of lilac colour running through it. Nestling on visible traps that were bigger than Marks fists.

He was 6'1" and a little thin, while she was inhuman. Massive mutant muscles bulging all across her 5'5" frame. As Mark already knew, no human had muscles as big or strong as hers in the world. He checked. He didn't know what she weighed, but her thick muscles made every Mr Olympia competitor look small. Both past and present. She was that big.

And those muscles were bulging bigger than ever as she lifted those colossally huge weights. She was almost as wide as she was tall. Her dress straining from her extreme back and tree trunk thighs. It was even tight around her slim, by comparison, waist.

As she started a new set of deadlifts, Mark couldn't help but pull out his 5" cock, and start stroking. His eyes never leaving her body. Not even to blink. He was mesmerized by every one of her muscles as they pumped even larger. With every rep. Every movement. Every flex. Her body look hotter and hotter. His pleasure building higher and higher. And when his grandmother's back burst out of her dress, he could no longer hold on and climaxed. Cumming into his underwear.

His grandmother ripped the remains of the dress off her body. Complaining about its flimsiness while unveiling her naked upper body. Mark was immediately hard again, staring at her naked chest. Her mammoth pecs holding aloft a pair of boobs bigger than his head. Clear in his view through the wall mirror. She bounced her liberated breasts a few times before returning to her workout.

It didn't take him long to cum again with his new and improved view as she further worked her back and arms. It was a crazy thick side tricep pose that pushed him over the final edge. The worst part for Mark though, was that this coincided with the brief moment of silence between songs. And he wasn't entirely silent himself.

He tried his absolute hardest not to make another sound until the music picked up again. Luckily for him, his grandmother seemed to be more focused on her own pump more than anything else. So when the music did pick up, he took his cue to exit the basement, and did so as quickly as he could.

Before his grandmother finished her workout, he'd already moved the boxes from his car, changed his pants and underwear and sat down in her kitchen. Eating a light snack he prepared.

When she climbed out of the basement herself, she was wearing a different dress and her makeup had also been freshened up. She noticed her cute grandson in the kitchen when she walked into the kitchen, searching for a protein rich meal. A smirk sitting across her wrinkled face.

"Hello there dear. So. Did you enjoy my little show?" she asked him out of nowhere. First question on the day he was moving in. Mark started coughing, choking on the air from the shock.

"You, heard me? Saw me?" he asked nervously after catching his breathe.

"I did not see or hear you down there. But I do know the smell of cum dear. It was quite pugnant. You  must have really enjoyed it." she informed him

"I, grandma, I'm." Mark stuttered.

"Hush there dear. There's no need to apologise. You should really get some more confidence sweetie. Learn to speak your mind. You can always be open and honest with me. So speak your mind." she interrupted. Trying to encourage and support him.

"Okay, grandma. Thank you. The truth is. The truth is, I love you." he confessed.

"And I love you too sweetie. Your my adorable little grandson." she responded with a sweet and caring smile before

"No. Not like that. I know we aren't blood related, and, I love you. I think you're the most beautiful and amazing woman. And I," he tried to make clear.

"I'm flattered dear. But I'm an old woman now. You really should" she told him but he interrupted

"I don't care about that! Your kindness, your sweet nature, your unbelievable body. Your pure heart. I've loved you since I was a child. And there's nothing you can say that is going to change that." he declared. His head held high. Proud of confessing the truth.

"Wow. You really did speak your mind there." she replied in shock. "Thank you. Your feelings do warm an old lady's heart. But sadly, dear. You just aren't capable of handling a woman like me." she let him know.

That statement shocked him to his core. But in a way, it also gave him hope. There was a chance. A path to being with her.

"I'll do anything. Anything to be with you. I'll become capable. I swear." he promised.

"Words can have great power dear. You should say some things so lightly." she warned him. "but anything you say? Okay then sweetie. If you follow all my rules. And my instructions. Then we can  see about things in the future." was her answer. A gentle but also conspiring smile could be glimmered from her aged face.

"Yes grandma. I'll do whatever you ask." determination in his voice.

"Okay then. First, you can call me by my name. Then, we can get to work dear."

"Yes, thank you. Miriam." he answered with a blushing smile.

The most kind and lovely smile appeared across her wrinkly face as she stared at her beloved grandson. Who she now hoped could soon become her new lover.

Over the next two weeks Mark followed every instruction sent his way. She trained him on how to lift weights properly. How to make a bed properly. Household chores. Proper diet and how to make protein rich food.

Some strict rules were also lain down for him to follow. Waking up early. No staying up late. Back before 7pm. But the most impactful one for Mark, the one he struggled with the most, was no masturbating.

After 3 days, he was horny all the time. More so in the presence of Miriam. His penis was hard every second he was near her. By the second week, he was cumming in her presence without even being touched. Miriam simply scolded him for his lack of control. Since then, he worked hard every day to control himself better. A tough challenge when his dream woman was around him every day. Interacting with him. And blasting mind blowing workouts on a near daily basis.

On what felt like just a normal day, it was 16 days after he had arrived, just before they sat down for dinner. Miriam served him a bowl filled with an odd smelling soup.

"I want you to eat every single drop. Lick the bowl even. I don't want you to waste a single drop."  she told Mark. More like an order.

And as with any order she gave, he complied without another word. Like a well trained loyal dog, he asked no questions and devoured the oddly flavoured soup. Not spilling a drop and even licking the bowl clean, just as she had ordered. Once he'd finished, Miriam brought out a banquet of protein and calcium rich food. Ordering him to dig in and not stop until we was ready to burst. Another order he complied with.

Mark was more tired than usual that evening. When he went for his good night kiss, one of his favourite rituals of the day, Miriam told him to enjoy his big surprise tomorrow. Mark wasn't sure about what she was talking about and was too tired to think about it carefully. He went straight to his bed and was asleep in a matter of seconds. His dreams that night were filled with his beloved Miriam and her massive, beautiful muscles. Nestling him close.

Mark felt strangely heavy when he stirred from his slumber. He felt more tired than he ever had before. His limbs and muscles ached more than any DOMS or injury he had in the past too. He planned to stay in his bed even longer even if it was against the rules. That was until he heard the familiar clanging of weights from the basement below.

As he tried to stand up, he felt that things were even more off. That soreness, that heaviness just wouldn't go away. His legs, they somehow, felt longer. He was so confused. Until he looked into the mirror. What appeared before his eyes wasn't the skinny body he was used to. Muscles. Thick, ripped, muscles.

He was huge. His body was full of big muscles. He could easily stand up in a men's classic physique stage and maybe win, only, he clearly didn't skip leg day with his thighs. He'd also grown a few inches. And not only in height. But before he got further lost in his miraculous new mass, he continued to hear the familiar clanking. And he couldn't resist who was working out in that basement.

There was no rule laid down saying he couldn't watch Miriam as she worked out. But Mark couldn't resist not masturbating to her ungodly large muscles as they pumped themselves larger. God even the sound of her workouts made him hard. His mental images turning him on nearly as much as the sight itself these past few days.

He wanted her. He wanted Miriam more than ever at this point. And he was going to show her that now, he could handle a woman as amazing as her.

There was no skulking this time. No hiding. Mark confidently walked down to the basement, baring all his newly acquired glory. He confidently strut down into the basement where Miriam was pounding heavy weights.

She was expecting his arrival. Hoping for a confident hunk of a muscle man to walk down those stairs as she was gazing at the mirrored reflection of the entryway. Her giant muscles pumped full of blood. Her crystal blue eyes more focussed as she hears the basement door opening. Licking her crinkled lips, smiling at the sight of the buff chunk of muscle hunk confidently striding down towards her.

Mark wasn't surprised to see Miriam curling dumbbells that weighed more than he could deadlift yesterday, but she was doing so completely naked. Her massive muscles, ample breasts, pert nipples and silver bush all exposed for the world to see. Well for Mike to see really.

"So deary. Like what you see this time?" she asked still curling the colossal dumbbells.

"Very much so." he gently replied.

"Think you're ready for a woman like me?" she questioned, a stern note in her voice.

"Very much so." he replied with confidence this time.

"I think so too. Feel free to take what you want sweetie." Miriam said as she put the superheavy dumbbells down and flexed her super pumped super biceps.

Mark approached behind his grandmother, and caressed her biceps. Feeling both her monstrous muscles and tanned leathery skin for the first time. His penis growing to it's new full and powerful size of 9.5" from the novel, mind blowing sensations.

"Can I kiss your lips?" Mike asked, a cheeky grin plastered on his face as his hands moved to her mammoth triceps.

"No need to ask deary. For today, I'm all yours." Miriam replied with a sweet smile.

Mark walked in front of his grandmother, leaning down before falling to his knees. His lips swiftly grazing abs before finding her lower lips. Kissing her thick, muscly and powerful vaginal lips. His tongue stroking her expanding clitoris when it was not exploring her inner depths. His hands caressing her quads, occasionally grabbing them for leverage. Before moving his touch onto her ripped muscle globe ass cheeks.

Miriam was pleasantly surprised by Mark's action, feeling a rush of pleasure she hadn't in years. One that can only be acquired with another. Her muscles rumbling from the sensation brought by his lips and tongue. She admired the muscle mate she had made for herself. Stroking his newly broad shoulders as his tongue and face dug deeper inside her, pushing her into a quick, but powerful orgasm. Blasting cum into his mouth.

Mark was a little surprised by how quickly he made her cum, becoming pleased with himself for a job well done. He devoured almost every drop of her lady cum that flew his way. Even licking the drops stuck to her silver bush. He enjoyed it so much, he didn't stop the kissing. Going for an encore performance.

But before she climaxed again, Miriam raised Mark up to his feet. His weight meaning nothing to her immense strength. Mark towered over her when standing up straight, by nearly a foot actually. Yet her muscles, were at least twice his size. And probably more than that really.

All of Mark's feasting hadn't only flooded her with pleasure, it made her hungry too. She pulled Mark in close, his engorged penis rubbing against her bugling abs before grabbing his thick buttocks and lifting him into the air. His cock gliding across her abs and nestling between her breasts and pecs. Its head poking through her cleavage. In perfect position for Miriam to kiss. Lick. And suck. And she did all of that with his ass in her hands and his weight held aloft by her strong arms.

Mike tried his best to hold on but came in under a minute of his grandmother's feat and fellatio skills. Her wrinkled lips created a seal on his penis head as he burst, suckling down every drop of his cum. Gushing out in powerful bursts.

She carried him over to the nearest weight bench before laying down across it after his orgasm quelled.

"I had to release some of your built up pressure sweetie. Couldn't have you cumming so soon when we really get started. And that was also a mighty good snack." Miriam told him as she flexed standing over the top of him. Getting him nice and hard again.

She leaned down over him, her face coming closer to his before pressing her wrinkly lips into his youthful pair. They exchanged saliva and tongue strokes. Separating with big, sweet smiles on their faces.

"You best be ready sweetie. Grandma likes it hard, and rough. And she's going to take everything she can out of you." was what she warned him before impaling herself on his bulging cock. Riding it and fucking him for hours upon hours on end.

It was long past lunch time before they stopped. Miriam was breathing heavy but still eager for more. Mark was still willing to please her despite his exhaustion. If it wasn't for their intense hunger, they most certainly would have continued. They worked together to prepare a massive feast for lunch that was devoured within minutes. Only to restart there rabid fuck fest, this time in Miriam's bedroom.

Mark's was living a new life from then on. He never had to touch his penis again for relief as he was fucking Miriam multiple times a day. He was also much stronger than he looked, lifting almost ten times what he could from before his big change.

Miriam confessed to him that it was her 'muscle soup', that was the source of their big and strong muscles. But ordered him to not ask for more or anything further about it.

He spent most of his days either working on his car or just being with Miriam. She loved to sunbathe and was grateful for him to lather her up in sunscreen almost every day. He loved to feel every inch of her monstrous body. Especially as he slowly rubbed every inch of her tight skin, spending the most time on each of her hulking super muscles. Sometimes being rewarded with a blowjob or an early afternoon fuck.

About halfway through the summer break, as he was working under his car. Miriam walked over, lifting the car off the ground with one hand to talk with Mark face to face.

"Your cousin Chrissy will be moving in with us tomorrow. So you'll need to pick her up from the train station when she arrives. And you don't need worry about a thing sweetie. Nothing's going to change between us." she told him with a wink of her baby blues.

Mark was a little confused as Miriam lowered the car, showing zero exertion from the act. Completely unsure about what was about to happen. And aroused by her yet again.

Part 2

Mark awoke the next morning in one of his favourite positions. Spooned into his beloved grandmother and lover. He awaited for her to wake up when she blessed him with a kiss before going down to the basement for an early morning workout.

He was warned that if he didn't work out regularly or intensely, he'd lose all the muscle mass granted to him. So he continued to follow Miriam's house rules. He worked out every day. Shared duties in the kitchen. Made the bed every morning, sometimes not his own bed. And helped keep the place clean and tidy.

It was after they finished the healthy, protein filled breakfast that Mark made, Miriam reminded him about his cousin Chrissy arriving that day. And that he'd need to pick her up at the train station.

Chrissy didn't live as far as Mark did before he moved into his granny's house. Only living across this state instead of across several. Mark was always jealous that Chrissy got to spend more time with their grandmother than he did because of this.

Chrissy was a far more athletic person than Mark ever was. A 5'9" girl with a cheerleader build, although she hated cheerleaders. Well, more athletic before he ate his granny's 'muscle soup' that is. She didn't even recognise Mark when she arrived at the train station. It was until the massive hunk of beef that she was staring at called out her name, did she recognise him to be Mark.

"Wow. What happened to you?" she had to ask.

"Oh. I started eating healthy and working out. Impressed?" Mark replied flexing his giant bicep.

"Bullshit. We can talk on the drive." she retorted with a contradictory scowl and a skip in her step.

They silently walked to Mark's car before driving off to their grandmother's house.

"It was grandma. Right?" was what she asked him. Excitement leaking from her voice.

"She got me into working out yeah. She even taught me how to make nutritious food and how to eat right." he replied proudly.

"I still call bullshit." sticking to her position

"But it's true." indigence in his voice.

"Okay then that part MAY be true then. But that's not how you got all jacked like that. Grandma did that. I want to know how." determined to get the true answer.

"Look. I can't tell you. You'll have to ask grandma about it." he conceeded

"Why did you get it first? I've been dreaming of getting a body like hers for years. I even negotiated to move in with her first." Chrissy confessed. Mark was stunned.

"You want to get huge muscles, like grandma?" was all he could squeak out. His voice even breaking a little.

"Yeah. Come on, she's fucking hot. You agree, don't you? That's why you chose to go to college here. Like me right? Can't believe we both had the same idea. And all thanks to my stupid dad, you get all buff before me. This is so unfair!" she screamed in frustration

"So, you like muscle woman, too? Your gay?" still confused about everything Chrissy was saying.

"I'm bi-sexual dingus. I mostly get really excited by big fucking muscles. On guys or girls, you big dumb steamy piece of meat." she replied, her eyes feasting upon his muscles that were streatching out an old t-shirt.

"Who? Me? I thought I was your lame, twig cousin?" a proud smirk across his face.

"Not anymore! You looked in a mirror lately? I'm so glad we aren't blood related." a lustful smiling creeping onto her face.

"Why?" while confusion spreading onto his.

"Firstly, so I don't share any genetics with your stupid,ass. And second, so I can fuck those sweet ass muscles of yours." she boldly declared.

"Sorry but I'm spoken for." he boldly declared. Leaving Chrissy confused for a moment before realising.

"No way. Grandma? Really? Damn, that's so fucking hot. Have any problems with me joining in? I'm sure grandma wouldn't mind." the lust oozing from her voice.

"What? No. You're not my type." Mark remained defiant.

"Oh, but I will be. I really can't wait to see grandma now." ended the conversation. Chrissy full of confidence in her future.

When they arrived at the house, Chrissy immediately jumped out the car and ran inside the house, looking for her grandmother. Mark 'volunteering' to take in her bags for her. An easy task for the new him.

There grandmother had already prepared lunch for there return. A healthy protein rich lunch,  including some of her amazing cookies. Made with less sugar and extra protein she told them with a big smile on her old face.

Miriam was extremely pleased to see her favourite granddaughter again. They'd always gotten along so well. Sharing many interests. Chrissy always reminded her of best friend whom long since passed. Mark too shared many traits with another of her closest friends. Maybe that's why she feels so close to the two of them she thought. And why she planned to tell them both the truth.

Mark was considerate enough to leave the two woman to each other that day. Spending his day taking car of car. He was going to college to study mechanical engineering. His primary hobby has always been cars. So when he got this old, non-functioning mustang for his birthday one year, it's been one of his greatest joys restoring it to working order. So whenever he couldn't be with Miriam, he was content working on his car.

Chrissy came out to let him know dinner was ready. She also thanked him for giving her time with their grandma.

As the two of them sat down at the dining table, Miriam brought out two bowls of a strange smelling soup. One of the bowls being around twice the size of the other. The larger bowl went to Chrissy while Mark got the smaller one. Mark heard the same instructions he heard weeks ago when last served this soup.

"I want you both to eat every single drop. Lick the bowl even. I don't want you to waste a single drop."

Mark knew what was coming by eating this and looked to his grandmother who only nodded silently in response before leaving them to eat. While Chrissy was unsure about the enormous bowl of soup before her, Mark gave her some words of advice.

"I'd do what grandma said. You definitely don't want to miss a single bite of this soup. You, really don't." flexing his bicep a little before he started to devour the soup. Careful not to miss a single drop.

Chrissy got the message and got to work eating her soup. By the time she was licking the bowl, Miriam returned with trays full of high protein and calcium rich foods for them all to dig in to, especially Chrissy. And even though she was already pretty full from the soup, her grandmother kept encouraging her to eat more.

Chrissy felt so bloated after dinner she was even getting dizzy. Miriam asked Mark to help her to her room before saying they should all get a quiet nights rest in their rooms. He got the message that he'd be sleeping in his bed tonight which would normally sadden him. But tonight, he was excited for the changes that awaited him the next morning.

Mark awoke to a familiar heaviness. A part of his brain get telling him to go back to sleep but another, more powerful force, drove him to get up. As he dragged himself out of bed, the changes this time were just as obvious. No longer could he be compared to a classic physique competitor. No. Heavyweight bodybuilder. But bigger. He'd crush the Mr Olympia contest with his new size.

His muscles proportionally were coming closer to Miriam's. He'd also grown more than a few inches and in more places than one. He was going to have to duck under all the doors of the house now. And probably have to squeeze in sideways now too.

Mark was flexing all his new muscles when he heard the oh so familiar sound of weights clanking in the basement. He smiled to himself as he moved to the basement. Hoping to find Miriam in her early morning workout. Proudly swaggering in his new birthday suit.

When he confidently strutted his hulking mass down the basement stairs, he saw a familiar but also unfamiliar site. There was a beautiful mass of muscle lifting colossally huge weights but the skin was paler than he was used to seeing. She was also taller, breaking 6'. With long red hair tied in a ponytail.

As he looked into the mirror, he saw her reflection and confirmed that she was his cousin Chrissy. Only now with muscles almost matching his own. Pumping them hard while completely naked.

"Look how fucking huge I am. This feels so fucking good!" she screamed after putting down the superheavy barbell and flexing a mind shattering most muscular. Cumming to her own reflection. Her juices travelling down her super muscular thighs, making Mark near enough instantly hard.

"Damn girl, your a fucking mutant monster." he told her.

"Damn straight I am." she said before turning to look at her cousin.

"Oh. And you. Can just fuck me right now." she said while licking her lips.

"I'll take that as a compliment." Mark said as he flexed his pecs and biceps.

"No you dumbass hot mountain of beef. If you don't bring that thick meaty ass to me. And that fuck stick you can barely call a penis. I'll chase you down. And then it won't be so fucking pleasant for you." she snarled at him, her lust and horniness dominating.

Mark quickly complied, his own horniness taking over. He waddled over to her with that bodybuilder walk when she quickly grabbed his head and shoved her tongue down his throat the moment he was within reach. Both lost in their lust for each other by now.

Their huge muscle bodies collided. Her giant breasts squeezed between her own titanic pectoral muscles and his titanic pectoral muscles. Her calf muscles flexed into diamond hearts, growing bigger than Mark's as she stood on toes for that kiss. And his penis, splayed across her thick bulging abs that she was flexing, just to excite him further.

After releasing the kiss, Chrissy threw Mark to the ground and straddled his waist. Preparing to mount his massive cock, standing tall at 15.5" and thicker than an extra wide soda can. Her pussy was already drooling for his mighty meat stick, awaiting the feast before it. Chrissy slowly lowered herself, impaling herself on Mark. Her new muscle pussy being filled by her cousin.

Mark raised his thick upper body from the floor and straightened his back. He was giving Chrissy a little muscle show as she was squatting deeper and deeper, thrusting more and more of his thick and powerful cock inside her. Mark went threw some of the compulsory poses calling them out to get Chrissy's attention.

By the time he called a most muscular, she had about 90% of his cock inside her. The sight of hulking muscles explode in size from his pose with the sensation of his penis pulsing inside her sent Chrissy over the edge. Exploding into another earth shattering climax. Her vaginal muscles attempting to crush his meat inside her while she forces her own upper body into another most muscular like pose.

Her bursting mass of mutant muscle with the intense pressure on his cock pulled him into a gushing orgasm of his own. His cum pumping inside her like a geyser erupting, the sensation heightening her own pleasure exponentially as well.

As there orgasms were subsiding, the sound of thundering stomps echoed from above. Before the the cousins could think, they heard heavy creaking from the nearby stairs. And when they turned there eyes to the reflection of the entryway, the duo almost orgasmed again.

Miriam like her grandchildren, was not the same as she was the night before. Her mutant musculature had expanded further into unfathomable mass. Her muscles so large, they now clearly impeded her movements. Her quads so thick she could no longer stand straight. Her back so wide, her hands could no longer reach her thick waist without hunching over. Her neck and trap muscles so thick, the were repositioning her head. Even with her extra few inches of height, she was still a massive sphere of mutant muscle mass.

She smiled at her naked reflection, resisting the urge to flex, before turning her body to face her grandchildren.

"What? Is my make-up okay? I struggled a little to apply it this morning with all these new muscles." she told them as she flexed a bicep that blew up her arm to almost match the size of her grandchildren's thighs.

"You thought I wouldn't have some of the soup too? I can't let you kids have all the fun." she informed them. "So Chrissy dear, don't hog Mark all to yourself. Grandma needs some filling from that meat of his too."

The grandchildren both holding back an orgasm from the sight of the absolute mutant beast that was there grandmother. They both desired her more than they did each other. And Chrissy couldn't wait another second.

She stood up from the floor, releasing Mark's dick from her muscular pussy's grip. Stepping close to her grandmother. She leaned down and locked lips with the shorter but much bigger woman. Her fingers grazing the muscle filled, tanned skin. Far larger and more vascular than she ever felt before. She was leaking more fluids from her muscle pussy and not just Mark's cum.

When she released her grandmother's crinkled lips. She started kissing her way across Miriam's unfathomable muscles, her lips indulging in every bloated inch of muscle they could reach.

"You aren't the only one hungry grandma. You're so fucking hot I want just devour every fucking inch of you." Chrissy told her through short pauses in kisses. Ending her final kiss upon her grandmother's nipple, preparing to suckle upon the tit.

"Language deary. There's no need for cursing. You've grown up so beautiful as well. I've never been with someone so muscular before." Miriam told Chrissy as she stroked her broad muscular shoulders. "Is it everything you dreamed of?" she asked her granddaughter before cooing from the pleasure erupting from her sucked nipple.

"Better. So much better. It feels better than I ever imagined Grandma. Your the absolute best." Chrissy told her as she recommenced her kissing. Kneeling down to Miriam's giant, thick abs. Each brick bigger than Chrissy's fist, extending from her stomach. Chrissy kissed and licked each of Miriam's bricks down the road to her muscular lower lips, just beyond the well trimmed silver bush. Her lips finally reaching there goal.

Miriam's clitoris was bulging. Engorged with blood to what could only be described as to an extreme level. Chrissy took great joy in sucking upon her grandmother's pleasure centre. Miriam was already building to a strong climax when Chrissy bit down her clit. Her old mind went blank from the shock. An orgasm coming ever closer to mutant mass of old lady muscle.

Mark was enjoying the show, but felt a little left out. He wanted his grandmother all to himself. But knew if he had to share her with anyone, he was glad it was Chrissy. And even better, a jacked up super muscle filled Chrissy.

Once Chrissy got down to their grandma's genitals, Mark decided it was time for him to join in. He moved to behind Miriam and stretched his arms around her continental lats, squeezing his thick arms between her mammoth thick limbs and her muscle stuffed torso.

His hands started by stroking her freshly kissed abs before moving up to her pecs and breasts. Caressing and massaging her beyond massive chest. He had to pull her body in closer to him, forcing his pecs to mash up into her mountainous back muscles, just to get a hold of her nipples. Both touches flooded Miriam with even more excitement. More pleasure.

As Mark pulled, massaged and even twisted her nipples, he also started to kiss her towering traps. All while Chrissy's nose and tongue were invading Miriam's vagina. And with one hard tug from Mark and a long, intense tongue stroke from Chrissy, Miriam burst into an earth shattering climax. Her lady cum barraging Chrissy's face.

Miriam had never been in a threesome before. And never in her dreams would it have been with two young, attentive, loving, muscle filled partners. Let alone her two favourite 'grandchildren'. Their descendents no less.

Miriam couldn't be happier. Her grandchildren expressing their intense love for her. She couldn't feel anything but blessed. Well, and extreme bliss from all their affection.

"So grandma. You still wanting some of Mark's cock? Or would like more of me?" Chrissy asked with a smirk. Her face slathered in her grandmother's cum.

"Oh sweetie. I want you both." was all she could reply before hoisting Chrissy up into the air. Chrissy's huge muscular body may as well have been weightless with how Miriam moved her about. It was time for her to please her grandchildren.

After a quick shift and adjusting her grip, Miriam spread Chrissy's thick thighs, Chrissy's bulging hamstrings resting in the palms of her hands.  Miriam then suddenly dove her wrinkly face deep into Chrissy's waiting pussy, pulling Chrissy towards her. As she did so, Miriam also leaned forward while also spreading her own torso thick thighs. Inviting Mark to join the fun. An invitation he accepted immediately without a word.

Mark impaled her wet, flush and inviting pussy, thrusting deeper inside her than anyone had penetrated her before. Miriam started to rotate her shoulders. Chrissy still putty in her hands, pussy never straying far from Miriam's face or tongue. Mark's penis being massaged her her powerful, dick crushing, metal moulding pussy muscles.

Mark gained extra leverage by grabbing on tightly to Miriam's Himalayan back muscles. Thrusting harder, faster and deeper than he had the past few weeks. His hips and enlarged balls slapping into Miriam's steel boulder bun ass cheeks and thighs.

Chrissy couldn't decide where she wanted her hands to go. Her own big, thick powerful muscles? Or the colossal mutant monster muscles of her grandmother? And there was also her enormous tits. Also begging for some attention. Her mind blitzed by the skills her grandmother applied with her tongue and face, Chrissy lost all control of where her hands went. Travelling between her tits, her abs, her pecs, her biceps, her grandma's working shoulders and even her grandmother's white hair with a hint of lilac.

Miriam worked hard to bring her grandchildren to climax not once, but multiple times over the next few hours. The threesome rode what could only be described as a near infinite sexual stamina that wouldn't stop this endless cycle of pleasure if not for another undeniable need. Hunger.

Even as the three of them prepared enough food to feed a dozen large men, they could not stop touching and teasing each other. The pangs of deep hunger the only thing stopping them from kickstarting the fucking immediately.

After devouring more than half the food, but still continuing to eat, Miriam decided it was time for a confession.

"There's something I need to tell you both. And I would have done so before, but I wasn't sure either of you would believe me. At least, not until you both experienced some evidence." Miriam started before a short pause.

"I'm a witch. And my 'muscle soup' is just an old family soup recipe, mixed in with a magic potion for strength and vitality. That's how we all got so big so quickly." Miriam pausing for another moment.

"Is being a witch, a genetic thing?" Chrissy asked.

"Sort of. Only descendents of witches can be witches. Thanks for asking sweetie. This leads nicely to my next confession. A long time ago, even before your parents were born. I joined a coven. It was only a small one. Just us three sisters. Life was so much fun together. Even when my sisters found male partners and got married. It was still fun being together. They even had wonderful, although ungrateful, children." Miriam explained.

"Wait, are you talking about my dad, and Chrissy's mom?" Mark interrupted. A hint of shock and excitement in his voice.

"No need to interrupt deary. I'll get to that. But yes, you are correct. Your grandmother's, my coven sisters. And their husbands. I chose to adopt and raise their children in recompense for not being able to help them. When. When. They were. Killed." Miriam confessed. Grasping her fist tightly, causing her bicep and shoulder muscles to expand. Her frustration clear. And her pain.

"I tried to live a more, normal life. After they were gone. Stop practising. Putting all my focus on raising your parents. They've probably told you some kooky stories from there childhoods. Ones that may sound a little exaggerated. Were probably true though." Their grandmother smiling for the first time since she started her 'confession'.

"But throughout that time. I was also watching something else. The police found my sisters' killers, but they got off with light sentences. By the time your parents were your age, their parents' killers were released from prison. I couldn't. Wouldn't let that stand. I wanted them to suffer. They needed to suffer. To feel the pain I felt of losing those closest to me. I wanted them to hurt. I wanted to hurt them." the anger, rage, Miriam expressed could be felt all over the room.

"So, I sought my solution in magic. I found a potion that would make me strong. Powerful enough to take my vengeance." Miriam left it silent for a few seconds before her final confession.

"Yes. I killed them. I tortured them. Just to make them suffer. I crushed their bodies until nobody could recognise them. Before I destroyed there bodies with fire. At least with what was left of them." fear strung across her old and wrinkled face.

"So. That's why you got those super muscles. Revenge." Mark stated. "All to kill people." Chrissy added.

"Yes. I swore I'd never use my power to hurt another soul. Magic and potions, they always come with a price or two. Some aren't so bad. Like with the strength potion. You only need to use that strength to keep it. If you don't, you lose it. And it can be quick too. So if you kids want to keep those muscles, you need keep up with those workouts. I might slow down a bit though. This might be a little too much muscle."

"NO!" both Mark and Chrissy screamed at the same time. "You look amazing grandma. Why would you want to change that?" Chrissy added. "You've been so big for so long. Why not try out this new size for a bit before making a decision. I mean, you did chose to stay all big and muscular after you got your revenge, right." Mark continued. Panic riddled in both their voices.

"I guess you are right deary. I really enjoyed the feeling of power I had. I guess I'll stick with this for a little while. Especially since you both seem to enjoy it so much." Miriam reconsidered.

"And you both seemed to get over that pretty quickly. Your grandma here just confessed to premeditated murder 2 minutes ago. Are you both alright with that?" she asked, as Mark and Chrissy looked to each other. Simultaneously smiling.

"We understand. Those people killed your family. Your coven. I, we can understand that. This doesn't change anything between us. You avenged our grandparents deaths. We shouldn't be scorning you, we should be thanking you. You even raised some our parents. So, thank you grandma. Thank you, Miriam." Mark spoke for the both of them before Chrissy added

"So, that means I can be a witch too? We could even form a new coven together!" she exclaimed full of excitement.

"Can boys, even be witches?" Mark questioned before Miriam answered them both.

"Yes they can sweetie. So you, both of you. Want to forge a coven with me? Being a witch can be very fun, but also dangerous. Are you both sure?" Miriam queried. Not wanting to get ahead of herself. Inside though, she was overjoyed by the idea of forging a coven with them.

"We've already done some stuff that was way more personal than that." Mark said before "And what's life without a little danger. It sounds fucking amazing." Chrissy added.

"Language dear. Words have power in the witching world. Where do you think the term 'cursed words' originated? I'll prepare the forging ritual tomorrow. Oh, but I have one condition. You both must graduate from college. If I hear that either of you start failing, or your grades start slipping. All the witchcraft is banned." Miriam firmly stated.

Chrissy and Mark both agreed but had just a couple of more questions for Miriam as they were finishing there meal.

"So, why aren't we doing the ritual today? Then we could start learning magic and stuff." Mark asked.

"Oh, but I thought we'd all continue what we started this morning. What do you sweeties want to do?" was her answer. Knowing full well what their decision would be.

They easily chose Miriam's suggestion. Witchcraft could wait a day for some unparalleled sex.

A side effect of the strength and vitality potion was an insatiable libido which tempered considerably after the first day. They'd still be incredibly horny especially when around each other but not to the extent they were feeling at this moment.

But before they got started again, Chrissy had one last question.

"Is there any more of that muscle soup left?" she asked with high hopes

"All gone at the moment. And it takes more than a month to make that potion." was her answer.

"Huh? But I was only here for a couple of weeks before you gave me the soup?" Mark questioned.

"I was already preparing it for Chrissy before you arrived. And it was clear when you arrived what you wanted. So I thought it best for you to join us. Chrissy had planned to move here months before you did. Wanting to be just like me she begged. So I prepared the potion. And when you decided you wanted to move in too. Well, I just thought I'd take it slow with Chrissy. Not rouse too much suspicion. But it's much better this way. You both remind me of my sisters so much. Marion always knew what she wanted, but struggled to admit it or take action. While Angela was always there to push everything along at her own pace, dragging us along with her. You're both so much like your grandmothers." Miriam explained, a warm and loving smile across her old lips.

"So, could you teach us how to make the strength potion then?" Chrissy pushed.

"When you both graduate, I'll make sure you both know how it's made. As with all my witchy knowledge. But that's after you graduate. Your parents spent hard earned money to send you both to college so you better not waste it dearies."
