“Dude, what are you doing on the floor?” Anton asked.
“Capturing art, my dude,” Roy replied with a weird grin, angling his phone to pan up and down his roommate’s body in a way that creeped Anton out.
“Are you gay or something?” Anton asked.
“No homo, bro, I swear!” Roy chuckled, continuing to record from his prone position as his roommate walked through the hall of their dorm to the living area.
“Uh huh,” Anton said incredulously. He didn’t know what was going on with his weird dorm cohabitater, but the way he was being looked at made him shudder. Anton didn’t have anything against guys who were into other guys, but at the same time he didn’t appreciate being leered at. He sighed and tugged at the sleeve that just didn’t want to stay on his shoulder today, causing his breasts to wobble. Sometimes being such a well-endowed dude was a curse, he mused as he clicked his high-heeled floral shoes over the cheap linoleum that was worn away in places, victim to the feet and furniture of thousands of college students past.
Coming to the tiny kitchen, Anton opened the fridge door and shivered as cold air spilled out and chilled his bare, hairless thighs. He flicked one long, white ear while contemplating whether to heat up yesterday’s last two slices of pizza or to nuke some of that lasagna Meredith brought over for their study session the previous day. Not that they had been able to concentrate much on their lecture notes. Anton smirked as he recalled the feel of Merry’s perky breasts in his hands, and the heat of her legs opening up to receive his… his…
Anton looked down into eighty pounds of white titflesh cleaved down the middle. Something wasn’t right. Were his breasts bigger today, or something? Somehow they suddenly felt unfamiliar and out of place. He cocked his hip and tried to concentrate, the cool fridge air causing his plump nipples to pucker up and poke obscenely from beneath the billowing shirt that fit him too tight in one spot and too loosely everywhere else.
Unable to figure out what he was bothered by, Anton gave up on food and grabbed a beer instead. He picked at the tab gingerly to avoid breaking one of his nails and was rewarded by the familiar hiss of depressurized brew sputtering through the opening before he levered the tab all the way forward, then back again. One of these days he’d have to find a way to satisfy his alcohol cravings without putting his manicure at risk. How had he managed to avoid such disaster all his adult life? Just lucky, he supposed.
When he got to the living area, Roy was already on the couch. Leering at him again. Like he’d never lived with another a guy before in his life and didn’t know how to keep his perving to himself. Anton grimaced and decided to sit on the love seat by himself, even if it meant suffering from window glare as he settled in to some Netflix. He took a long drag on the cheap beer and uttered an oddly under-powered belch, then set the half-empty can into his cleavage. The cool aluminum felt nice on his sweaty skin, a tiny patch of relief from the stale dorm air.
“When are they going to fix the AC?” he asked Roy while flicking a long lock of purple hair off to one side and scratching an itch at the base of his horn.
“They said it probably wouldn’t be until Saturday,” Roy replied. Even without looking, Anton could tell by the sound of his voice that Roy was still creepily lingering on him with his eyes.
“Dude, what’s wrong with you today?” Anton asked, picking the beer can out of his cleavage and taking another drink while waiting for his perv roommate to explain his behavior. “Why are you looking at me like a piece of meat? Cut it out, man, it’s gross.”
“You really don’t notice, do you?” Roy asked, an odd satisfaction in his voice.
“Notice what? All I can deal with is you staring at me like a cheerleader doing splits,” Anton replied, crumpling the empty can and lobbing it at Roy across the coffee table. It bounced off Roy’s shoulder and clattered to the floor, eliciting no reaction from the target.
“Nice shoes you got there, bro,” Roy said with his weird smirk.
“What about ‘em?” Anton asked, lifting his feet up to see them over his expansive chest. They looked normal to him.
“They really draw the eye away from your fat tits,” Roy said sharply.
“Nevermind my tits, asshole,” Anton said defensively. “You act like you’ve never seen a guy’s rack before, or something.”
“How many guys have a rack like yours, bro?” Roy shot back.
“None,” Anton answered. “Certainly not you, little man.”
“Exactly, bro,” Roy said cryptically. “I know a lot of chicks with tits, but no chick can compete with yours.”
“Stop comparing me to chicks, damn creep-ass weirdo!” Anton said angrily. He was fast running out of patience and had already resolved to report this perv to the dorm supervisor at the first opportunity.
“Hehe, this is awesome!” Roy giggled, making Anton’s flesh squirm.
That was the straw that broke the camel’s back. Anton hoisted himself up and strode angrily back to his own room. He started going through the college’s web portal to find the number to call for his dorm supervisor, angry at himself for not saving the orientation PDF he downloaded on his first day back at campus.
An unwelcome knocking interrupted his quest. “Piss off,” he shouted over his shoulder.
“Open up,” Anton said from the other side. “And make sure you’re naked first.”
Anton sighed, determined not to put up with this any more than he had to. Putting his phone on the desk, he kicked his shoes off into a corner by his bed and undid the fly on his tight black shorts. It was an effort to wriggle free of them, but his panties came down more easily with a firm stretch to slip over his broad hips. Anton angrily pulled the shirt up over his far-reaching breasts and lifted it over his arms and head, careful not to snag it on his horn. Shaking purple hair out of his face, he tossed the shirt onto the back of his chair and stomped angrily with bare feet to the bedroom door. He braced himself and started thinking of the perfect words to use against Roy, then twisted the knob. There the perp was, leaning against the door jamb and devouring Anton’s figure with his eyes while pursing his lips in a silent whistle.
“What is it?” Anton asked, crossing his arms over his naked breasts and tapping a foot impatiently.
“Invite me in and sit on my lap,” Roy said nonchalantly.
“Get in,” Anton demanded, pointing to his bed against the far wall. He glared at Roy while the roommate sauntered in and sat down on the bed, hands splayed out behind him. Anton mounted his lap, feeling a little uncomfortable at the obvious stiffy Roy sported in his jeans that dug into his naked thigh. “Now tell me what you came here for.”
“Don’t you think it’s a little odd for you to strip down and sit on another guy’s lap?” Roy asked with his weird lopsided smile as he regarded Anton’s impressive bust hovering mere centimeters away from his own.
“No, I don’t,” Anton snapped. “What’s gotten into you today?”
“Don’t you think it’s a little weird that you’re doing whatever I say?” Roy questioned him again.
“Stop talking in riddles, dipshit,” Anton replied, steadying himself with his hands against Roy’s knees. “The only thing that’s weird in here is you. Now tell me what your deal is before I call the campus cops.”
“Okay, sit right there and be a good girl for me,” Roy said, taking one hand and reaching into a pocket to retrieve his phone.
“Do I look like a girl to you?” Anton asked, exasperated beyond measure.
“Yes. I used this app I found online to turn you into one. Not just any girl, but a nice MILF-ass Rarity. And the best part is, I used this option that keeps you from noticing anything’s changed!”
“You’re crazy, you know that?” Anton asked. “You can’t change people with some app. That thing’s probably draining your Venmo account right now.”
“Nah, I know it works. Just now I made it so that you’ll do anything I say. That’s why you got naked and let me in, old buddy old pal! Jiggle those tits for me,” he said.
Anton was at his wits’ end. He tried to think of some way to convince Roy that he was being ripped off by a fake phone app, meanwhile he had to use both hands to cup his enormous breasts and shake them enough to satisfy the latest request. “Look, Roy, prove it, okay?” he said, trying to keep his composure as best he could. Maybe if he convinced Roy this was fake the creep would leave him alone. “Just try and change something about me right now.”
“Okay, but it’s hard to improve on perfection,” Roy answered with barely restrained glee as he fixated on the shaking bosom in front of him. “How about if I can change your name and stuff like that? Will you believe me then?” he asked.
“Fine, whatever, just get it over with,” Anton said. His arms were getting tired of pumping his breasts up and down while all this carried on. The faster he could make Roy see this wasn’t working, the better.
“Okay. Just let me change a couple of things here… like so… and with this part… make sure… you can… notice it… and there. Okay, Anton. What’s your name?”
“Rarity,” Rarity replied. “See? Nothing- wait, I mean Rarity. Rarity! No, I’m Rarity! Okay, how are you doing that?” he asked, undisguised concern in his voice now.
“Well Rarity, have you always been a girl?”
“I… I’m not… I mean…” Rarity’s face contracted into a confused expression. “What are you doing?” she asked. “Stop making me think I’m a girl!”
“But you are, my dear,” Roy sneered as the naked anthro vamp continued shaking her stuff in his lap. “In fact, let me take the limiter off,” he tapped his phone, “and… there. Now do you think it’s normal for a guy to have porno tits and a big booty?”
“Oh my god!” Rarity cried in shock as the reality of her figure landed on her like a ton of bricks. “How are you doing this?”
“I told you, the same way I’m doing this,” Roy said as he tapped the screen of his phone a few more times.
Rarity suddenly gasped as a hot, tingly sensation exploded inside her body, racing to fill her flesh from horn to toe. An incredible exhilaration surged within her, catching her breath and causing her tummy to twitch. She was suddenly extremely aware of two things: herself, sensually awakened with immediate need, and Roy. Roy, bouncing her on his lap, probing beneath her bare thigh with his throbbing trouser-snake, hands shamefully empty of her glorious curves! If only she wasn’t so busy shaking her chest at him, she’d have his clothes torn off like tissue paper.
“Oh my god,” she said again, this time with a different tone of voice. “Roy, I need you!”
“Come and get it,” he replied with a triumphant smile. The next thing he knew was his head cratering the pillow of his roommate’s bed as she slammed his body down hard, bouncing him up three inches from the mattress rebound, not even waiting for him to land again before gripping the bottom of his shirt tight in her hands and jerking hard. The cheap material screeched loudly as it separated and split up to his neckline. Immediately, slender white hands were sliding up to his pecs and two heavy weights plopped onto his hips, followed immediately by a hot, wet mouth planting sloppy kisses onto his upper belly. A sharp point prodded his chest painfully, almost breaking his skin as Rarity smacked a trail of smooches down his abdomen, pulling her enormous breasts along and pushing against him, walking down his body with her hands until her face was hovering over his crotch. Explosive blasts of hot breath spread over his lower half as she paused to pant heavily before slipping her well-manicured nails around his waistband and gripped his zipper pull with her teeth.
“Careful down there!” Roy called as his navel caught on the tip of her horn. She grunted something in reply and unfastened the button of his fly and tried to pull his pants down in one motion. All she succeeded in doing was lodging them around his knees, freeing the pressure that held his cock down so that it cantilevered up and tented his boxers eagerly. “Don’t you dare damage the merchandise!” he warned.
“Mine!” Rarity declared desperately. She gripped his boxers with both hands and brought her teeth over the button, severing the threads that held it fast with her teeth. Turning her face off to the open side of the bed, she spat the fastener out and started shimmying the knit material until she successfully maneuvered the opening over the tip of Roy’s engorged purple head, freeing his shaft through the fly. She paused only a second to let her eyes come together and bring the split helmet into focus before closing them and nuzzling the length of his dick cheerfully with her cheek. “Mine!” she repeated, voice muffled by Roy’s hairy upper thigh.
“Damn, I’ve created a monster,” Roy grinned, locking his phone screen and setting it on the nightstand of his formerly-male roommate before bringing both hands up behind his head and leaning back to enjoy what was coming to him.
