Ms. Robbins 3

Throughout that semester and the next, Ms. Robbins juiced, trained, and bulked up like she never had before. She increased her steroid intake, revelling at becoming freakier, and took to HGH and other experimental drugs that bloated her physique with even more meat.

By the end of the spring semester, her clothes were stretched taught at odd places as her burgeoning physique became impossible to hide. Students started making comments behind her back about the muscle bound professor. The running joke was that she had butched out so much that she was more man than most of the men on campus.

These rumors only encouraged Ms. Robbins further. She was so turned on by her hyper athenian physique, spurred on by Jimmy’s infatuation with her muscles, that all she wanted was more - more muscle, more mass, more freakiness.

It was the last day of class and Ms. Robbins wore a button down blouse and skirt. Only the blouse was stretched so tight that the buttons looked like they were about to pop off. There were gaps between each button through which you could see the rippling sinew of her chest and abs. The arms were stretched to near translucency, and her thick lats look like they were about to tear through the sides of it. Her traps had become so massive that they bulged up toward her ears, making the blouse impossible to button all the way to the top.

Her skirt was no better, as her abs had become so bloated with muscle and her glutes so thick that she couldn’t button the skirt at the waist. It was supposed to be a loose skirt, but her massive thighs had it stretched tight.

Ms. Robbins was rumbling on in her lecture - her voice had become several octaves lower - as the students snickered behind her back. 

“She’s a man!” whispered one female. 

“She looks like she ate a bodybuilder!” said a boy.

“She’s probably got a bigger cock than you!” said another.

Ms. Robbins heard the comments. She smiled, and her pussy spasmed, gushing juice. A wet spot formed on the front of her skirt. Freaking people out like this turned her on.

Jimmy sat near the front practically drooling at Ms. Robbins’ display. His hard on was raging and he wasn’t even attempting to hide it. Ms. Robbins noticed and gave him a lewd, knowing smile.

As the lecture drew to a close, Ms. Robbins turned and put her hands on her desk. Her bulging pecs nearly tore through the front of her blouse. A button popped, exposing more of the striated beef that composed her blocky pecs.

“And that,” she said tensing her arms. Tears started forming on the sleeves of her shirt. “Is the end of my class. I hope you enjoyed it as much as I did!”

Then Ms. Robbins suddenly gunted and flexed both of her toaster-sized pecs. They engorged and surged forward, blowing the remaining buttons on her top. The class gasped as her rippling, striated pecs surged in cabled relief, bloating to the size of two toaster-ovens, with her nipples pointing straight down. 

“Oh my god,” exclaimed one student. Several got up and ran out of the room. 

Ms. Robbins laughed. She stood tall and flexed her abs, bucking her hips. Her bulging abdominal wall blasted through the flimsy waist band of the skirt. It tore and fell. 

Underneath she wore a translucent white lace thong. Only it did little to contain her unruly coarse bush or the thick, wet pussy lips that formed her musculed cunt. A student puked at the sight, overwhelmed at the extent of her muscular development, even there, at her muscular cunt.

Ms. Robbins grinned like a mad woman as she flexed her pussy lips and they bulged. It looked like they were eating the front of her thong. As most of the remaining students got up and ran, repulsed, Ms. Robbins moaned. Her cunt spasmed and belched more juice, soaking her thong and forming a puddle beneath her feet. Stitches popped as the thong stretched to contain her flexing cunt muscles. With a snap, the thong shot off. 

Jimmy stared, slack jawed, at the inhuman display. Ms. Robbins strode forward, grabbed his desk, and tore the table-top off the metal chair. She grabbed Jimmy’s sweat pants and tore them in half, exposing his huge member. Then and there, she mounted him, with two female students left watching, mouths agape.

Jimmy moaned as she mounted him. She flexed into a double-bicep pose, and her massive biceps and triceps tore through the remains of her sleeves. Her biceps engorged with mass, looking like striated, football-sized piles of worms.

“Tell me Jimmy,” she said, slowly sliding her thick pussy up and down his cock. “Am I big enough yet?”

“Unngh,” Jimmy moaned. “Nooo!”

Ms. Robbins smiled a big shit eating grin. She locked eyes with the two remaining students while she continued to hump Jimmy. She said, “He’s right… unngh yea…” she said, continuing to sensually hump Jimmy’s cock. “I’m not nearly big enough…. Nngh!... Don’t you agree?”

The two female students both nodded.

“Oh YES!” Ms. Robbins moaned. “Go ahead,” she said, putting her hands on her hips and flexing her traps, lats, and pecs. Her muscles bulged like big, bloated balloons of striated beef.

“Stroke yourselves to my massive muscles!” she cried. The two women complied,  sliding their hands down their pants and stroking their pussies to the most erotic thing they’d ever seen.

“I’m going to get even huger!” Ms. Robbins moaned, thrusting on Jimmy’s cock harder and faster. 

“BIGGER THAN ANY FEMALE BODYBUILDER!” she cried as her pecs surged into Jimmy face. “BIGGER THAN ANY MAN!” 

The girls moaned, crying “yes, more, bigger!”

She crunched down into a most muscular as she pistoned herself on Jimmy’s raging cock. “BIGGER THAN A FUCKING BULL! BIGGER THAN A GOD DAMNED GORILLA!”

The girls moaned louder, orgasming, willing Ms. Robbins to grow even bigger. “YES! MORE!” they cried.

Ms. Robbins’ pussy started spasming. “OH YES!” she cried. “A BIG BUTCH BEEFCAKE! A HUGE, MEAT HEADED MONSTER! A SUPER ROIDED MASS OF FREAKISH MUTANT MUSCLE!”

Ms. Robbins’ muscles rumbled and bloated. New striations appeared and new bulges bubbled to the surface as she seemingly grew right before their eyes. The girls lost it, orgasming wildly, and Jimmy couldn’t hold back. His cock bucked and pumped it’s massive load into Ms. Robbins.

Ms. Robbins absorbed his cum like a tick sucking on a host, bloating bigger and thicker, engorging with his cum. Her traps swallowed her neck, and her pecs surged like two gnarled, mutant heads.  Her quads bloated bigger, enveloping Jimmy’s lower body and dwarfing his waist. Her lats bulged to the sides, inflating like huge meat wings, lifting her arms.

“OH FUCK YEAH, I’M A ROIDED UP MONSTER! AND I’M GONNA GET EVEN FREAKIER! I’M GONNA GET SO JUICED UP THAT I’LL BE THE MOST MASSIVE BUTCH-ASS BITCH ON THE PLANET!” she cried, her overly muscled cunt finally succumbing to the eroticism of the moment, and it gushed with juice as her cunt muscles spasmed.

When the three students and the professor finally stopped panting, Ms. Robbins said, “Let’s talk about summer assignments, shall we?”
