Ms. Robbins 4
🕑 Added 2019-08-07 11:00:02 +0000 UTC
Ms. Robbins kept her word over the course of the summer and stuffed herself with every supplement, growth hormone, and steroid she could get her hands on. She also stuffed herself with protein, gorging on meat, eggs, and whey any chance she got.
Her body absorbed it all and grew. She was now more muscular than any woman Jimmy had ever seen, real or imagined. Her traps were so big that it looked like she had no neck. Her lats were so wide and thick that she looked wider than she was tall. Her pecs were two huge, striated masses of meat, without an ounce of breast tissue. Her abdominal wall was a thick stack of eight bloated pool cues, covered in rippling veins. She had obliques that looked like thick, blocky love handles and gave her mid section a barrel shape. Her thighs were thicker than most men’s waists and her calves jutted out like bulging heart-shaped softballs.
But bigger muscles weren’t the only changes. Her blonde hair had started getting stringy and falling out, so she just shaved it off. Her nose and forehead got bigger and thicker, a product of the HGH. Her jaw grew, too, and now it jutted out, and muscled striations bulged from her jaw. She looked mean and hugely intimidating.
“Look at what I’ve become,” she growled into the mirror as Jimmy stared, awestruck by her sheer intimidating mass. Her voice was a gravel baritone now, and was just as intimidating as the rest of her. She was topless - she had no need for a bra with her massive, rock-hard pecs. She wore a white lace thong that struggled to contain the mass of her bulging, muscular pussy.
She flexed her pecs, first the left, then the right, and each split and separated into two distinct bulges, an upper and a lower. She had a groove between them three inches deep, and they each rippled with striations. She grunted and flexed them both, sending her erect, shot-glass-sized nipples pointing straight at the floor. Thick blue veins engorged across her alien pectorals and squirmed like angry worms burrowing under her skin.
“You’re a goddess!” Jimmy breathed. He was totally naked, his big cock erect just from watching Ms. Robbins’ flex her monstrously hypertrophied physique.
“But I’m still not big enough,” Ms. Robbins said, “Don’t you agree?”
Jimmy’s eyes widened. She was the biggest, most muscular human he’d ever seen! And she still wanted more?
“Don’t act so surprised,” she said, glancing over her massive trap muscle to view his painfully erect dick. “You want this as much as I do. Don’t you.” It was more a command than a question.
Jimmy’s heart beat faster. He couldn’t help it, he was totally lost in this muscle fantasy come to life. “Yes… yes I do!”
Ms. Robbins chuckled. “I knew it. You like this freaky shit just as much as I do! And that makes me want it EVEN MORE! Now get me the gear, now!”
Jimmy retrieved a large syringe and a large bottle containing a cocktail of experimental growth hormones and steroids. He filled the syringe and looked up at Ms. Robbins.
“Do it!” she whispered. He did - he injected her ass and pushed the plunger while Ms. Robbins growled a low, sultry growl.
“MORE!” she said once he had finished.
“More? But that’s already more than-”
“MORE!!” Ms. Robbins shouted. Jimmy complied, injecting another full syringe, then another. This was more than five times the recommended dose.
“YESSSS!” Ms. Robbins hissed as she crunched into a side chest pose. Veins all across her body squirmed and bulged, feeding the crazy cocktail to her already massively hypertrophied muscles. They seemed to bulge and expand right in front of Jimmy’s eyes.
Jimmy watched with awe as new bulges bubbled up on her back, throbbing and pulsing, competing for space. She flexed her arms and insane, angular bulges erupted from her biceps and triceps. It looked like she had shoved two footballs in each arm as they swelled nearly to the height of her fists. Her glutes, too, pulsed and grew. They were so striated they looked like two hulking pumpkins.
Ms. Robbins turned to face Jimmy, smiling a toothy, predator smile. Her lips pulled back past her gum line as she crunched down into a most muscular.
“I’M SO FUCKING YOKED!” she hissed as a cascade of vein-encrusted sinew bulged outward from her pecs, abs, and thighs. Veins inflated like pencils across her thick thighs and her crazy abdominals. It looked like they all fed into the massive bulge of meat that was barely contained by the front of her lacy thong underwear.
Pubic hair crawled half way up her abdomen and spilled out of the sides of the thong. Jimmy could see the thick pussy lips pulsing with muscular growth, bulging outside the confines of the thong. Her clit, itself a mound of muscle, bulged further, stretching the double-XL sized thong normally meant for a morbidly obese woman. But Ms. Robbins’ mega-pussy filled it out to nearly bursting.
Ms. Robbins released her flex and stalked forward.
“Watch me become the most mega-butch bitch on the planet!” she rasped. Jimmy laid flat on his back and she loomed over him, resting her fists on cantalope-sized obliques.
“Watch my BEEFY cunt GROW!” she hissed. Veins pulsed across her thighs and abs, feeding those already thick pussy lips. They bulged, along with her massive clit, as stitches popped.
“OH FUCK YESSS!” she hissed as a cascade of muscle converged on her mid section, bloating her musculed cunt. She flexed it open and then grunted as it sucked at the thong, tearing it from her ass cheeks. Her mighty muscled cunt inhaled the thong. Fist-sized protrusions bulged around her muscled pussy lips before suddenly contracting, spitting the thong out with such force that it slapped against Jimmy’s chest.
“Oh yeah, baby,” She said, flexing up an arm and turning her face toward it. “I’m so fucking jacked up, I’m not even human anymore!” she said. Then she extended a long tongue - too long for a normal human, and utterly laced with muscles - to her bicep and licked it.
“You’re a mutant! A muscle freak!” Jimmy squeaked.
“I’M A FUCKING MONSTER!” Ms. Robbins cried, flexing open her super-cunt. She slowly lowered herself onto Jimmy’s member, then clamped down. Jimmy gasped. Ms. Robbins stood, holding Jimmy aloft with the sheer power of her muscled pussy.
“GIVE IT TO ME!” she cried, contracting her pussy muscles to thrust Jimmy’s huge cock in and out of her muscular mound without even touching him. “CUM IN THIS MASSIVE MOUNTAIN OF FUCK BEEF!”
She grabbed her own pecs and moaned, feeling the bulging, angular masses, letting her fingers probe the deep cuts and striations. Her eyes rolled back into her head as she imagined those freaky pecs growing even bigger.
“Unngh” Jimmy moaned, unable to hold back, “Oh god, you’re so fucking massive… I can’t hold it…”
Ms. Robbins growled and glared down at Jimmy as her pussy sucked at Jimmy’s huge member. “THAT’S RIGHT JIMMY, I’M A GOD! YOUR MUSCLE FUCKING GOD! OFFER UP YOUR CUM, NOW!”
Then her super-powered pussy pistoned him like a jackhammer. Jimmy groaned, has nutsack bucked, and he ejeculated what felt like a gallon of cum into Ms. Robbins’ muscular pussy. She moaned as he did so, then unceremoniously released his cock and let him fall to the ground with a thud. Not one drop of cum fell from her pussy. Her overly-muscled cunt had inhaled it all and absorbed it all.
“Thanks for the protein infusion,” Ms. Robbins said. “I’ll need it to grow even bigger.”
Bigger? Jimmy thought with fear. Then his lust took over, and he was hard again. Ms. Robbins just smiled.
