Aiden tried to act normal, but inside he was panicking. He couldn’t use the chronivac to change himself right now without Mark catching on. Aiden turned in his chair to watch Mark rummaging around in the kitchen. He caught himself admiring the muscles of his broad back, and how strong and powerful his forearms looked. As Aiden admired Mark’s handsome, manly body, he started to feel strange sensations emanating from his new parts. Instead of a growing erection and an ache in his balls, Aiden felt only warmth and a strange hunger. Mark stopped what he was doing when I noticed Aiden staring from across the room.
“What’s up, bro?” he asked, arching an eyebrow and schmearing mustard on a slice of bread.
Aiden shook himself. “Nothing, lost in thought. I’m gonna take a shower.” He quickly muttered, getting up from his chair.
“Have fun,” Mark snickered, returning to his sandwich construction.
Aiden darted into the bathroom and shut the door behind him, too flustered to bother locking the door. He turned on the shower for noise and then quickly stripped himself, pausing with his hands around the band of his boxers before pulling them down too. Once again, he was greeted with the sight of a pink, moist, and slightly puffy vagina nestled between his thin but still masculine looking legs. The thing looked completely out of place, even on his modestly muscled and almost hairless body. He reached a quivering finger down to touch the soft, sensitive folds, gasping when his fingers brushed his clitoris. It felt like the head of his penis, but the sensations coming from his clit and from deep within him were far different from an erection. He was just about to insert a finger between his new, moist folds when suddenly he heard a thundering of footsteps and the handle of the bathroom door. And just like that, Mark barged in on him on Aiden in all his naked glory.
“Dude, say something next time you eat all the deli meat…Holy shit!” Mark had instinctively raised his hand to shield his eyes from seeing the smaller man’s junk, but faltered when he saw his roommate had no junk to speak of. Peering closer, however, he saw the unmistakable mound and lips of a pussy where the young man’s cock should be.
“Shit, you have a pussy!” he shouted, pointing at it as if Aiden had no idea.
“Shut the fuck up, Mark, I…” Aiden snarled, but Mark cut him off.
“Where is your cock? Did you even have one?” he laughed, bending over so he could get a closer look.
“Yes, I had a cock!” Aiden shouted defensively. “I just, accidentally lost it for a while…” he muttered, trying to cover himself.
Mark stood up straight and crossed his arms over his big chest. “What do you mean, you lost it?” he said, still staring at Aiden’s pussy.
“I got this computer program; I thought it was a joke but it actually works! And I got a little curious and…changed myself.” Aiden explained, then he got angry again. “And I was about to get it back before you came home early!”
“Why bring it back?” said mark, his tone suddenly becoming light and seductive. He stepped a little closer to Aiden. “It actually looks kind of nice on you.” He reached down to move Aiden’s hand.
“Mark, come on, this is weird enough as it is.” Aiden stammered, feeling flush as Mark’s broad chest and stubbled face loomed closer.
“Yeah, but its also kind of hot.” He gave Aiden a devious look that both intimidated him but also excited him. “And it’s a very nice looking pussy,” he purred, reaching with one of his thick fingers to stroke around Aiden’s new, sensitive opening. Aiden moaned and found himself leaning his naked body against Mark’s tall, looming frame. Mark inserted his finger and started to delicately draw it in and out, chuckling as Aiden moaned and buried his face into Marks chest. He looked down to see an impressive bulge forming in Mark’s pants. He’d seen Mark’s cock a few times by accident, as roommates eventually do. The thick, nine-inch cock had been the subject of his late night fantasies, but he’d never dreamed of getting a chance to play with the straight man’s beautiful dick. Mark had teased Aiden a few times with the sight of it, but he had never entertained the thought of treating the little twink to his meat; he had enough fun with the ladies as it was. But now, as Mark inserted another few finger into Aiden’s hungry new pussy, he was sure that this was the real deal, and he was never one to pass up a chance to play with good pussy.
With his thumb, he began to rapidly massage Aiden’s throbbing clit while his fingers continued to probe and massage within him. With his other hand, Mark reached over to turn off the shower, and then he effortlessly lifted Aiden up and hefted the little man against his muscular chest. Aiden wrapped his legs around Mark, moaning as his big hands squeezed and massaged his firm ass. Mark surprised Aiden by delivering a rough and forceful kiss onto the younger man’s smooth mouth. Marks tongue snaked its way into Aiden’s mouth to meet his own, and the two kissed and fondled as Mark carried Aiden to his bedroom. He unceremoniously dropped Aiden onto his bed, taking another long look at Aiden’s pussified body while standing with his thumbs hooked under the waist of his tight jeans.
“Well?” He said expectantly. “Aren’t you going to undo my belt?” he said, staring down at Aiden with a devilish smirk on his face. At first Aiden was too out of sorts to move, but staring at the promising bulge in Marks pants encouraged him to listen to the man’s command. He slid off the bed and came down to his knees, reaching out to undo the belt and slip off the button. He pulled down Marks jeans, leaning back for a moment to let the man kick them to the side. Aiden stared at the fat cockhead peaking from the leg of Mark’s boxers.
“Come on, pussyboy,” he coaxed. “I can see you want to see it.” Mark shrugged out of his shirt, exposing his hairy and well-muscled chest. Aiden gulped, gripping the boxers and pulling them down Mark’s tree-trunk legs.
Mark’s cock bobbed up from its cotton prison, nine inches of thick hot cock, with a throbbing purple head and a pair of large, high-riding balls. The sight of it made Aiden’s new pussy come alive like a 440 engine. Without even waiting for the word, he reached out for Mark’s cock and took the head straight into his mouth. Mark chuckled and moaned, watching the smaller man work his thick cock with a sense of deep satisfaction. He placed a hand on Aiden’s hand, helping to coax his thick meat deeper and deeper down the smaller man’s throat. Marc stood there and enjoyed Aiden’s ministrations for another few minutes, letting the boy get his cock nice and hard and ready for the pounding it was about to give him. Mark had wanted to fuck Aiden’s pussy the moment he saw it; he was shocked at how eager Aiden had become at letting Mark have his way with him.
When he had enough, he pulled Aiden away from his crotch, shuddering as his schlong slid out of Aiden’s mouth with an audible pop. Aiden gasped and wiped his mouth on the back of his hand before reaching down to grip his hard cock. But his hand found only his warm, moist pussy; he began to finger and stroke himself anyway while Mark loomed over him and watched while stroking his giant man-cock.
“That pussy turned you into a total cockslut,” he laughed, releasing his cock and letting it slap against his thighs. “Though from what I heard, you were pretty talented before.” He said, grabbing Aiden and pulling him to his feet. Before Aiden could say anything he was shoved backwards onto the bed, and the wind was knocked out of him as Mark jumped on top of him, letting his greater weight rest on the smaller man’s frame. They began to make out a bit more while Mark fingered and rubbed Aiden’s hungry pussy. He leaned back on his knees, grabbing his cock by the base and positioning it in front of Aiden’s moist pussy, teasing his lips with the tip.
Aiden writhed and moaned beneath him, “Oh, god please…”
Mark stopped, “Please what?” he purred against Aiden’s ear.
“Please, fuck me,” he forced himself to say.
“Well, you said you wanted a cock. So, let me give you one.” And with that, mark thrust the head of his cock into Aiden’s waiting pussy. Both men groaned; Aiden was reeling as Mark’s cock parted his lips and entered him. Mark didn’t stop or pull back, but instead continued to slowly slid his thick cock deeper and deeper into his roommate.
“Oh my god, you’re so fucking tight,” Mark growled as he bottomed out. Aiden felt like he was getting split like a log. Mark’s throbbing cock seemed to be stretching Aiden’s vagina to the limit, yet every centimeter of skin his man-cock made contact with felt electric with pleasure. Mark began to thrust in and out of Aiden, increasing his pace and his depth as Aiden’s gasps and winces of discomfort turned into moans and squeals of pleasure. Soon, he was driving his schlong into Aiden with gusto, his heavy balls slapping against Aiden’s ass. Aiden had his legs wrapped around Mark’s waist, his finger’s tweaking Mark’s big nipples while he threw his pussy back to meet Mark’s thrusts. Mark fucked him like this for another five minutes before pulling out and flipping Aiden onto his stomach. He collapsed on top of Aiden, thrusting his cock back into his moist hole before laying his weight on top of Aiden and resuming his fucking. Aiden’s face was slowly getting pressed into the mattress as he was fucked hard in the prone position, Mark’ dick seeming to reach even deeper into him than before in this position. He moaned and whimpered as Mark licked and nibbled the back of Aiden’s neck. After another ten minutes of this, Mark stopped his thrusting and rolled them both over so that he was on his back, with Aiden on top.
“I need a break, pussyboy. Ride my fat cock.” He commanded, folding his hands behind his head. Aiden, still with Marks cock inside him, moved his legs under himself and began to rapidly lift and drop his body on Mark’s cock. At first the new position was uncomfortable, but as he gyrated and bounced, he discovered some new motions and patterns that made his pussy quiver and Mark let loose a deep, growling moan. Soon he was rocking himself on Mark as hard as he could while the man’s big hands roughly massaged his firm ass cheeks. As Aiden rode Marks cock with gusto, he caught sight of himself in Mark’s bedroom mirror. There he was, his lithe toned body rocking up and down as a fat schlong slid in and out of his freshly minted snatch. Beneath him, a big, powerful man groaned and threw his head back, his be-stubbled face contorted in pleasure. Compared to Aiden, Mark was a paragon of virility and manliness, and the stark contrast nearly made Aiden go over the edge. Suddenly Mark’s grip tightened on Aiden and stopped his movement. Aiden yelped as felt himself get repositioned for the fourth and final time. Mark pulled his engorged cock out of Aiden, who yelped at the sudden withdrawal of sensation and the subsequent emptiness he felt within him. Mark climbed off the bed and roughly dragged Aiden so that his ass and legs were hanging over the edge. He gripped Aiden’s legs and shoved his full nine inches into the boy, just as Aiden was starting to miss the big thing. Mark hammered into Aiden with savage force, groaning and grunting until with a low and mighty growl his balls tensed and he came. Aiden could feel the giant cock pulse and throb within him as the big man, this real man, came hard within him. The realization that a man had ejaculated his load within his new womanly parts sent Aiden over the edge, and he came to, his vagina clamping down around Marks spent member with each pulse of pleasure. They collapsed on the bed, Mark spooning him with his softening cock still embedded in Aiden’s pussy. As they collected their breath, Aiden found himself drawn tightly against Marks hairy chest by his strong arms. A calm sense of contentment was settling in him; his pussy felt warm and relaxed from the pounding massage Mark had given him. He realized that he’d just lost his virginity for the second time, and Mark was the man who had taken it. He felt oddly possessed, and even more odd was how good and happy it made him feel.
Mark cleared his throat and was the first to speak up. “Damn, boy. That’s one hell of a pussy you made for yourself.” He said, playfully tugging his cock from within Aiden.
“I guess I should take that as a compliment,” Aiden sighed in response.
“You should,” Mark agreed.
“I can’t believe I got a chance to try that monster cock of yours.” Aiden laughed. He felt Mark’s deep chuckles reverberate against his back.
“Yeah, I always knew you wanted it. You took it like a pro, not bad for your first time.” He said.
“Dude,” Aiden muttered, “You totally took my virginity.” He snickered.
“Yeah,” Mark drew his head back, feeling his cock begin to harden again within Aiden. “I guess I did.”
They lay there for a few minutes, both contemplating the new and interesting turn that their roommate relationship had taken. Mark liked to keep himself inside his sexual partner while they rested in post-ograsmic bliss, and with Aiden he felt no different. He thrusted his still semi-hard dick a little bit deeper into Aiden, smirking to himself when he felt the smaller man squirm and moan in his arms.
“I’m gonna miss this when I get my dick back,” Aiden purred, before nodding off. This piqued Mark’s attention. As a roommate Aiden was as likeable and easy-going as anybody else, he could have hoped for; Mark had been untroubled by Aiden’s sexuality, even going so far as to tease the boy and enjoy how it stoked his ego. But now he was starting to think of Aiden a lot differently. Sure, he looked like a man, but Aiden’s pussy was as cute and feminine and delicious as the many others Mark had encountered in his life. And here it was, eager and living in the bedroom right next door to his. Mark decided that Aiden would be staying like this a little longer, maybe even permanently if he could convince the young man.
Mark waited a few more minutes before carefully extracting himself from around Aiden. He pulled his cock free, chuckling when the boy moaned and rolled over, but didn’t wake. Without bothering to dress, Mark sauntered back into the living room and over to the computer to see what Aiden had been up to. He was met by a complicated-looking program with a myriad of different options; he focused on a profile labeled ‘Aiden’ and reviewed the stats. He saw the option for Aiden’s genitalia set to ‘Human’ and ‘Female’, with a little timer counting down from two minutes short of a full twenty-four hours. Mark selected the options for time, the curser briefly hovering over ‘Permanent’ before clicking on ‘Indefinite’. He took care to set a password on the program as well, something Aiden had carelessly overlooked.
He was about to close the laptop when Mark noticed a table with his name on it as well, with a list of surprisingly accurate stats about his height, his weight, sexual preference, dick size, everything. Mark leaned back, several wickedly good ideas coming to his mind about what else to change about himself and his new, live-in pussyboy.
