Oh my god, oh my god, It’s finally time!” Whitney was buzzing with excitement as they walked in the dark to the quad. It was the first Body Modification Day of the semester, when the Sexual Chemistry and Gender Engineering departments offered free transformations to the students. It was always chaos - nearly every student had something that they wanted to change about themselves. Classes were canceled; the Institute needed all hands on deck to handle the crush of patients, and everyone skipped class anyway.

Supplies of the most popular serums sometimes ran out, so people started lining up hours in advance. By the time Jesse and Whitney arrived at 3am, the queue was more than 400 people deep. They put down their camping chairs and wrapped up in blankets.

“It’s five hours until they get started.” Jesse pulled out his tablet. “You want to watch a movie?”

“Sure!” He fired up ‘Scott Pilgrim vs. The World,’ and soon realized that modern movies were rather different in this new reality.

Whitney squeezed his arm. “This is my favorite orgy in the movie - it’s hilarious. Do you think they went too big with Ramona’s tits? I know it’s comic-accurate, but it messes up the framing sometimes - they only really fit in wide angle shots.”

“I don’t remember Michael Cera being so cut… or hung.” Jesse’s eyes were glued to the screen.

“Yeah, after Arrested Development he wanted to get away from the ‘dorky son’ roles. I really liked him in Red Rocket.”

They watched and chatted for a while, but after thirty minutes Whitney fell asleep, head resting on Jesse’s shoulder. He pulled her blanket tight around her and finished the film.

Around six, Institute hunks started passing out pamphlets about the transformation technology - Jesse’s pamphlet. He briefly skimmed it - he had written it all into existence eight hours ago after all.

RegROWTH: Regeneration and Reconfiguration of Organisms, Westfall-Thomas-Harker Process. A Brief History of Transformational Science.

The long path to the RegROWTH Process began in 1956, when Alan Turing and his husband jointly disproved the Collatz Conjecture… Westfall’s work in Sexual Number Theory won her the Fields Medal in 1958, while Westfall, Thomas and Harker jointly won the Nobel Prize in Chemistry the following year… Department of Defense funded the use of RegROWTH serum products to regenerate lost limbs and organs of returning Vietnam veterans… The Institute was given the first patent for a commercial RegROWTH serum product… the gold standard for cosmetic and gender-affirming transformation, with over 30 million doses administered worldwide since 1995.

“That’s what Sexual Mathematics does, you stupid cherub,” he said smugly.

Jesse and Whitney were nudged awake once the line started to move. They bundled up their stuff and shuffled forward. It took the better part of five hours to reach the registration desk. The same Goth girl from the Medical Center tapped at a tablet, clearly overwhelmed and exhausted. She scanned their student IDs, tapped a few times. “Ok what do you want?”

“Two doses of Boob Juice please!” Whitney smiled hugely at Jesse, her dream about to come true.

Goth Girl yawned, tapped the tablet, then took a long pull off her coffee cup. “That it?”

Whitney turned to Jesse. “What do you want? Cock Juice maybe? I’m not complaining, but having an anaconda never looks bad on your resume.”

Jesse hadn’t considered changing himself - he was just here to support Whitney - but she wasn’t wrong. They did have a whole porno to make… “Yeah, Cock Juice for me.”

More tapping, more yawning. “Ok, Boob Juice, plus Cock Juice for the stud. Anything else?”

“Double Boob Juice, please,” Whitney repeated.

“Double Boob Juice for the slut.” Goth Girl handed back their IDs. “Ok, done. The technician will scan your IDs. NEXT!”

It was another hour before they reached a treatment tent. A haggard stud in a lab coat made them disrobe, then laid them down in adjoining cots and scanned their cards. A machine on the desk whirred to life, spinning back and forth, shooting jets of clear liquids into small vials. He inserted a vial into his injection gun, then rolled his chair to Whitney.

He strapped her arms into restraints on the cot. “This is going to be intense. Your breasts are going to tingle and itch like you’ve never felt before - especially with a double dose. The restraints will keep you from scratching yourself. If you feel yourself growing faint, just go with it. The whole thing should take about two minutes.” Then he gave her the shot.

Jesse saw the mix of hope and fear in her eyes. He reached out and held her restrained hand.

“Thank you,” she murmured - then gasped. Her hands spasmed, trying to reach for her chest. Jesse saw goosebumps cover her pale skin… then those goosebumps started to swell. Hundreds of angry bumps soon covered each breast, like she’d crashed into a beehive tits first. They grew by the second, her chest now lumpy and misshapen. Whitney turned panicked eyes to the medical stud, who waved dismissively.

“It’ll even out in a second. Trust me, this is like the eightieth boob job I’ve done today. The burning should start now.”

She thrashed hard against the restraints and gritted her teeth. She let out a groan of profound discomfort as the growth accelerated. The ugly lumps began to merge as they grew, and her nipples suddenly expanded as well, areola spreading like puddles of melting ice.

As promised, it was all over in two minutes, and Whitney Choi was now the proud owner of an amazing pair of G cups, firm and lovely. Her nipples were huge compared to before. The stud unbuckled her and she ran her hands over them, gasping with pleasure.

“Yeah, they’re gonna be pretty damn sensitive. That can be tweaked down the line, but your body won’t be able to catalyze any more breast serum until at least next semester. Wear soft bras. Details are in the post-care email.”

He turned to Jesse. “Your turn brother.”

Jesse took his place and let the medical stud restrain him. Whitney took his hand as the needle struck home.

After a few seconds, an intense tingling started in his groin. He sat up as best he could, watched his penis grow painfully erect - then grow erecter. It just kept growing, past anything it had ever done before. The shaft was on fire, the head purple and throbbing, as his cock grew and grew. It swelled out as well, a balloon filling with meat instead of air. His scrotum loudly complained as his balls expanded. His whole body felt like it was covered in ants, and Jesse felt the blackout coming.

Then the burning in his crotch faded away. Jesse looked in wonder at his massive new cock. It must be 10 inches long and twice as thick as it was before. He spent a moment marveling at it, then froze. The burning hadn’t stopped everywhere. His chest was on fire. Goosebumps were starting to rise.

“Doc!?” he groaned.

The medical stud put a reassuring hand on Jesse’s shoulder. “Yeah, the dick always expands first in a serum cocktail. Your boob job should feel very mild by comparison.”

“WHAT!?” Jesse and Whitney shouted in unison. As the lumps bubbled up, Jesse passed out.

Jesse, Whitney, Goth Girl and the medical stud all sat in the office of Doctor Caldwell, Director of the Transformation Labs. Jesse slouched, arms wrapped tight around his new C-cup breasts. Whitney had an arm around his waist.

“I’m terribly sorry Mr Farmer. Ms Green misinterpreted your friend’s request for a double dose of breast serum as a request for each of you to get a single dose.” He turned stern eyes to the girl and she withered. “Which is exactly why we process patient requests One. At. A. Time.”

“Doctor Shannon, in turn, failed to double check your request before injection. Another egregious breach of protocol.” Caldwell removed his glasses, pinched the bridge of his nose. “In short, Mr Farmer - it was a complete clusterfuck. I cannot apologize enough. There will be an inquest, where you’ll need to testify. Go to the Student Law Center as soon as possible and speak to an advocate - they’ll advise you on your legal rights.”

“Naturally we’ll correct the mistake as soon as humanly possible. The Medical Center will get you a prescription for catalyst accelerant, and perform regular blood tests to watch your levels - but even in a best case scenario it will be three months before another breast serum will have any effect.”

“Jesus Christ.” Jesse put his head in his hands, making his boobs jiggle in his shirt.

Whitney stood up and hugged him fiercely, her new breasts squeezing his head from both sides.

“It’ll be ok Jesse - it’s only for a few months. You’ll be flat as a board for spring semester, I promise.”

He stood up, hugged her back, tension fading in her embrace - though it was disconcerting feeling his sensitive breasts pressed against hers. He sighed heavily and looked at the Professor.

“I just want to go home.”

—

Whitney brought Jesse up to his apartment, reassuring him as they walked. As they entered, he raised his voice. “I’m home and I brought a guest!”

“Who are you talking to?”

Jesse sighed. “Nobody - just a joke.”

She squeezed him hard, boobs pressing into his side. “Can I hang out with you for a while?”

He nodded gratefully. “That would be wonderful.”

They cuddled on the couch, watching Parks and Recreation and talking. Jesse was still hunching, curled up on himself. “Thanks for the support Whitney. I’m sorry if I’m a grump. I’ll… I’ll adapt.”

“I’m sorry you have to adapt. I’d have taken your dose if I’d known.”

Jesse snorted. “You wouldn’t be able to walk if your tits were any bigger.”

Whitney pinched him hard on the arm. “Don’t underestimate me! I’m small but mighty! I could carry the tits of ten women!” They both laughed hard at that, and Jesse unwound a bit.

“Listen Jesse, it’s gonna be fine. We’ll get you some sports bras, and no one will notice if you don’t want them to. Besides, boytits are in right now! This might work in your favor!”

Jesse gave a long and labored sigh. “As long as I’m shot from the collarbone up and belly button down, it won’t impact the porno at all.”

“We’ll all figure it out together - Ethan’s a great director, he’ll make sure you look your best.” Whitney got up from the couch after a final squeeze. “Which door is the restroom?”

“Right. Bedroom is on the left.” She went in and shut the door. The moment she did, the laptop on the counter started buzzing. Jesse groaned inwardly and got up, opened the lid.

“What do you want?” he softly hissed.

The mute icon was on the screen. The cherub was sitting at a computer desk, smoking.

::Surgery? What a silly idea!:: it typed, sticking its tongue out.

Jesse typed furiously. ::If you did this, you’re dead!::

::Wasn’t me! Might’ve been the boss, but it might really have been an accident. You made a big change - sometimes there are unintended consequences.:: He put up a hand to stop Jesse from typing. ::You didn’t do anything wrong - this isn’t a punishment.::

::I’ll fix it tonight. I’m sure I can come up with something that’s sexy but still lets me get rid of these things.::

The cherub shook it’s head. ::No project tonight. I haven’t gotten any messages from the boss.::

::What? I thought it was every night!:: Jesse smacked the screen in irritation.

The ashtray on the desk spilled on the digital floor, and the cherub gave Jesse a dirty look. ::No, it’s whenever the boss wants. Two in a row was just a coincidence.::

“Hey Jesse?” Whitney called from the bathroom.

He didn’t look away from the laptop. “What’s up Whitney?”

“You remember when I said things were going too fast last night?”

“Uh huh…” He started to type something sarcastic to the cherub, but there was a knocking noise from the bathroom door. Jesse looked up.

Whitney was naked, leaning against the doorframe, arms crossed beneath her huge breasts.

“Changed my mind.” She walked into the bedroom.

Jesse’s jaw went slack, then he jumped when the laptop shut itself and powered off. He started to move, walking in a trance to the open door, but halfway there he groaned and fell to the floor.

“Jesse?” Whitney stuck her head out, then ran to him. “What’s wrong!?”

“Pants… pants…” Whitney looked down - Jesse’s huge new dick was rock hard, pinned painfully inside his snug jeans. She giggled, undid his belt and pulled his pants down. It sprang out at full mast, rocking slightly from the recoil.

“Holy shit,” she gasped. “This thing is gonna look great on film.” She began to gently stroke and Jesse shuddered. Whitney leaned down and kissed him deep, hand still moving along the vast expanse of his shaft.

She shifted, pressed herself hard against Jesse - and felt her breasts touch his. Jesse opened his eyes, shifted uncomfortably.

Whitney pulled away, just a bit of space between them. “Jesse, would you take your shirt off for me?”

After a pause, he complied, pulling the t-shirt over his head, exposing his new breasts. Whitney touched them, gently, rolling the nipples in her fingers. “You look so amazing.” She squeezed his cock. “There’s no part of you I don’t want to touch.”

Smiling, he got up on one elbow and kissed her, hands tangling in each others’ hair.

Then Whitney laughed and pushed him down. “Time to put that boot camp training to the ultimate test!” She slid down Jesse's body, breasts pressing hard against every part of him.

Whitney stopped when she reached his nipples, sucking hard on one and drawing out a gasp of pleasure. “See? Not a bad thing at all.”

Then she continued her descent, and took the head of his cock in her mouth while staring into his eyes. There was none of the overwrought porno lust in Whitney's eyes now, just a sweet sexual delight.

She did her best to swallow Jesse's monster, but there are limits to even a pornstar’s oral skills. Whitney got about half of it before she started to gag. She backed up, then started bobbing, using both hands to supplement her mouth.

After letting her work for a minute, Jesse grabbed her waist and spun her around. He buried his face in her snatch, licking and slurping, delighting in her gasps and squeaks.

They continued for several minutes, pleasure mounting, but Whitney pulled up for air. “Wait, wait! Don’t you dare cum yet!” She turned back to look at Jesse. “Do you have any lube?”

“Drawer - bedside table!” he gasped. She darted out of the room, leaving Jesse’s erection throbbing in the air, but returned in a moment Astrogel in hand.

“Ok, we’re gonna do this. Gotta get that thing all up in my guts!” Jesse laughed as she poured the lube liberally into her hands - then gasped as she worked it onto his cock.

“By the way, I saw the toys in your drawer. We’re going to give those whirl next time.” Whitney looked at her work, appraising, then applied a second round of lube. The astroglide dripped down his shaft like melted wax.

“Alright… alright…” Whitney was working herself up. “Nice and slow.” Then she positioned herself above him, and started her descent. It was slow going, carefully lowering herself onto him, sometimes pulling back if things got uncomfortable. Jesse was in delicious agony as she worked. It took a full minute before she bottomed out.

“Jesus…fucking…Christ…” she whispered, eyes fluttering.

“Are you ok?” Jesse shifted to face her and she moaned long and deep.

“Yes.. oh yes.” She grabbed his hands and moved them to her tits. “You just.. Hold on tight.” Slowly, carefully, she rose up along his incredible length, then started to ride.

It didn’t take long for either of them. The sheer sensation, so many nerve endings - they both came hard and fast. Whitney stuffed her hand into her mouth to muffle the cries of pleasure as Jesse bucked and moaned. His cum squirted out from inside her as she collapsed on to his beautiful chest.

“We are gonna be superstars!” she declared.
