placebo pt 7

Within weeks Jenni looked absolutely unreal. She had turned herself into a monster. The sexiest monster on the planet. She now weighed 240 lbs. She was thicker than she was tall. Her arms were 25” and her quads a freaky 38” thick. She had razor-sharp definition, with less than 1% body fat. Every time she moved, her muscles cascaded with waves of sinew across her entire form, including her neck and her face.  She looked in the mirror and loved what she had become. She flexed her traps, which practically swallowed her head as they reached past her ears. They looked like meat appendages growing on top of her back, and they were covered in striations and veins. She flexed her lats and they inflated like meat wings, covered in sinew and freakish veins. They reached past her elbows and lifted her arms, which she could not lower past 45 degrees when she flexed her lats.

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 freak!” I breathed in awe.

"You think that’s freaky? I'll show you freaky, babe!" Jenni snarled, raised her arms, and flexed. Biceps the size of baseballs exploded from her arms, with thick blue veins snaking around them. The thick veins, throbbing to her quickening heart beat, expanded with each beat - bigger and bigger, until they were nearly the size of garden hoses. Then her arm slowly started to expand. Jenni let out a long, soft moan as her biceps slowly expanded past softball size, then larger, until they peaked at 28" of freakish mass, split with striations and sick vascularity. She released the flex, put her hands on her hips, and grunted softly as she flexed her pecs.

I just stared as the muscle fibers in Jenni’s pecs bloated, split, and multiplied before my eyes. Etched notches in the groove between her pecs grew more pronounced as her pecs expanded. Her b-cup tits seemed to shrink, dwarfed by the huge beefy pecs from which they were suspended. Suddenly she rolled her hips forward as her mid-section exploded in cabled relief. Her abs looked like a stack of eight baseballs with freaky veins running all over them, as they slowly expanded with growth. Her obliques squirmed and vibrated with growth.

Then she released her flex, bent forward, and crunched her arms downward in a most-muscular pose. Her traps exploded up to her ears as a sickening grimmace twisted her face. She grit her teeth as every muscle in her body vibrated with growth. Veins popped from her forhead and snaked down her cheeks as even her face exploded in disgusted vascularity. "ughhh!" she grunted deep, squeezing every last bit of growth from her overdeveloped physique, and her entire body expanded another inch.

It was unbelievable. Jenni now seemed able to force her muscles to grow at will. How was this possible?

Jenni moaned, her hands running all over her freakish mass, overcome with lust for her own muscles.

“Oh, I can feel it babe,” she moaned. “Inside me, like a thousand angry bees, just wanting to bust out!” Then she flexed every muscle in her body.

"hugg!" she moaned as her muscled pulsed and expanded. "hunnngg!" Her muscles surged with growth as a sound like creaking leather filled the air - her skin being stretched over her burgeoning muscles. "HUNNGG!!!" she cried, face crunched, fists digging into her temples. Her hugely pumped physique expanded, as her heart pounded, pushing more and more blood into the multiplying muscle fibers. "HUUUUNNNNNG!!" she cried out again. Then she straightened up suddenly. "RRRRAAAAHHHHHH!" she roared, streatching her arms out and upward, the peaks of her muscles soaring skyward, her head tilted back. She smiled, and looked down at me.

“Oh babe, look at me now!”

I nearly pissed myself. Jenni had become the most muscular thing I had ever seen, human or animal. Her calves were huge, demented, beef-filled footballs of muscle. Her thighs, my god, they hung over her knees by inches, and bloated out like watermellons straining her skin. Her abs looked like a stack of 8 oversized softballs packed under skin so tight it was nearly translucent. Her waist had to be 40" of solid muscle. Veins thicker then her fingers snaked around her legs and her torso. Her pecs were just enormous, thicker then two phone books, and b-cups looked like tiny, veiny balls stuck in the corners of two huge, immensely shredded blocks of beef. Her lats were so thick, so large that they held her arms out at 45 degrees. And her arms - her biceps were bigger than basketballs. Her head was swallowed by the most giagantic traps imaginable - she had no neck at all, just solid, shredded beef from the top of her head down to her toes.

"I'm a fucking mega-muscle queen!" Jenni roared.

I stood dumbfounded, but my cock was hard as a rock. Jenni saw it, obviously pleased with the effect she had on me. She moaned as a cascade of muscle converged on her mid section, bloating her musculed cunt.

“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!” I squeaked.

“I’M A FUCKING MONSTER!” Jenni cried, flexing open her super-cunt. She slowly lowered herself onto my member, then clamped down. I gasped. Jenni stood, holding me aloft with the sheer power of her muscled pussy.

“GIVE IT TO ME!” she cried, contracting her pussy muscles to thrust my cock in and out of her muscular mound without even touching me. “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” I moaned, unable to hold back, “Oh god, you’re so fucking massive… I can’t hold it…”

Jenni growled and glared down at me as her pussy sucked at my huge member. “THAT’S RIGHT BABE, I’M A GOD! YOUR MUSCLE FUCKING GOD! OFFER UP YOUR CUM, NOW!”

Then her super-powered pussy pistoned him like a jackhammer. I groaned, my nutsack bucked, and I ejeculated what felt like a gallon of cum into Jenni’s muscular pussy. She moaned, then released my cock and let me 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,” Jenni said. “I’ll need it to grow even bigger.”

Bigger? I thought with fear. Then my muscle-lust took over, and I was hard again. Jenni just smiled.
