Ms. Robbins pt 5 - mutation

“Let’s see just how much more meat packing you can handle,” Ms. Robbins said with a maniacal grin, “Because I want MORE!”

Jimmy trembled, unable to conceive what more muscle on Ms. Robbins’ frame could possibly look like. She was already so tremendously, mind-bendingly jacked. There didn’t see to be any more room on her frame!

Before Jimmy could react, Ms. Robbins injected herself with an entire liter of gear. Then she grabbed a five-gallon bucket of protein powder that was mostly powder and had the consistency of wet cement. It must have contained over a hundred thousand calories, and perhaps fifty pounds of protein. She chugged it with masculine grunts. Her belly bulged out like a pregnancy with all that extra protein was ingesting.

After draining the bucket, Ms. Robbins tossed it away and smiled maniacally. She looked Jimmy right in the eyes as she rested her fists on her muscular hips. Then snarled and flexed her pecs. They bulged into rippling masses with inhuman cuts and striations rippling across them. Her nipples pointed straight down on the floor due to the excessive mass in her phone-book sized pecs.

“My pecs,” she grunted, “are so BUTCH!” and they were, with pulsing blue veins rising to their craggy, rippling surface, and little black hairs sprouting around her dark, thick nipples.

“But they need to be BIGGER!” Ms. Robbins shouted through grit teeth. She grunted again and her pecs responded, swelling bigger. Her abdomen, bulging with all that extra protein, began rumbling as her insane physiology began consuming it and transforming it into new muscle mass.

Ms. Robbins focused on her pecs, directing her body’s incredible, juiced up muscle-mass production directly into her them. They responded, expanding audibly as her skin stretched to accommodate pecs that surged to toaster-sized masses.

Jimmy’s jaw dropped at the incredible growth of her already inhuman pecs. He was shocked and awed, but Ms. Robbins was far from done.

“We’re going beyond human today, Jimmy,” Ms. Robbins growled seductively. Then she grit her teeth and grunted louder. Her pecs bloated into two shelf-like masses, sticking out two feet from her body. Then, when they seemingly couldn’t grow any larger, a bulging mass of muscle began to bloat out from the side of each pec-shelf. Ms. Robbins growled as the masses grew, pressing outward, forming a new block of muscle on both sides of her pecs.

Ms. Robbins breathed in a huge breath, then crunched down on her pecs again, and there was a sound like rubber stretching as her two new distinct pecs fought for space on her frame. She snarled and tips formed on the two new pec-protrusions, and right before Jimmy’s eyes, they morphed into thick, brown nipples.

Ms. Robbins finally released her pecs, then smiled madly.

“Look at me now, Jimmy! I just grew two more absolutely ALIEN pecs!” Then she bounced all four of her freakish pecs rhythmically.

Jimmy was so overwhelmed that he puked. Ms. Robbins laughed, then smiled a big shit-eating grin as she noticed that despite his disgust, Jimmy had a raging hard on.

“Oh, you love this shit! But I’m not done, Jimmy!”

Suddenly, Ms. Robbins flexed down her insane abdominal wall. Her muscled abdominal wall began to grow. Each individual brick began to push outward against her skin. Bulging meat and veins fought against her skin, and Jimmy could hear a sound like creaking leather.

Ms. Robbins moaned, feeling a churning, burning sensation in her abdomen. She rubbed her expanding muscle gut as layers of chunky she-beef continued to protrude and solidify, each brick of her ten pack seemingly trying to outdo the others. She grunted as she slapped her muscle gut, each thud louder than the next. After one minute of growth she could finally see her expanding muscle gut starting to grow past her ridiculous four-pec shelf.

“HA! I can see it! YAGGHHHH!! MORE!” She bellowed as Jimmy stared with a mixture of disgust and awe.

Ms. Robbins began tensing and twisting her abs to speed up the growth. She put her massive arms behind her head and did ab crunches, further pushing out and pumping up her muscle gut. Her thick wall of abdominal muscle relentlessly surged forward straining her skin to the point where large strips of stretch marks began to form. She rubbed her growing gut almost as if to give it encouragement to continue to grow more and more. Her gut now stuck out two feet. The churning muscle of her belly was starting to fade, but Ms. Robbins willed her disgustingly vascular and insanely pumped ten pack to begin to shift and split.

Through sheer force of will she began to separate each ab brick into two. Sweat poured down her face as she agonizingly bloated her gut with now twenty ab bricks. The muscle tendons were clearly visible through her almost translucent skin. Thick throbbing veins covered her entire being, from forehead to toes, including her insanely large and pumped gut. She was absolutely disgustingly pumped and ripped and she loved it. She slapped her gut and walked toward Jimmy.

“I’m a fucking FREAK!” she moaned as she flexed down into a most muscular pose. Her traps inflated, bulging up past her ears, practically encasing her head with striated muscle. She grunted and her traps surged higher, above the crown of her head. Sweat poured down her brow as she began to focus her freakish muscle-building ability on her traps. New protrusions bulged out the sides of each trap muscle, surging with vascular, striated beef. Right before Jimmy’s eyes, Ms. Robbins grew two new traps beside her already massive mounds.

She looked absolutely unreal. Beyond anything human. She stood with a maniacal smile as she bounced her four pecs alternately. Then flexed her four traps and they bulged, making her look like she had five heads sitting on the widest shoulders imaginable.

Jimmy gagged, but his cock spasmed. He moaned as he blew his massive load watching Ms. Robbins turn herself into a muscled monster.

Ms. Robbins smiled. “Good, you’re still on board. Let’s continue!”

She suddenly flexed her massive quads and they engorged with garden-hose-sized veins. Her quads expanded over her knee caps, dwarfing them. Her calves followed suit, bloating bigger and bigger, clearly visible from the front. Her face suddenly scrunched up in concentration as she did it again, multiplying muscle fibers to a freakish degree.

Each quad split and grew, a new head sprouting to each side, bloating bigger, as if she had two quad muscles on each leg. Her calves split and bulged into two softball-sized appendages bulging from the sides of her lower legs.

“Mmmmm, RAHHH!” Ms. Robbins growled as her leg muscles multiplied obscenely, reaching mutant territory.

Jimmy’s eyes were wide, his mouth hung open in shock at the mutant muscle freak in front of him. But he felt hornier than ever, and his cock had engorged again even after cuming so recently.

Ms. Robbins noticed. “YOU LIKE IT, AND I LIKE IT! CUM ON MY FREAKY MUSCLES!!”

Jimmy stroked his cock like a machine, watching without blinking as Ms. Robbins flexed and bounced all of her mutant musculature. He came what felt like a gallon, splattering all over Ms. Robbins’ four-pec shelf of mutant beef.

Ms. Robbins grinned maniacally. She swiped her finger across her cum-soaked chest and licked it.

“Very good, Jimmy, very good!!”
