>>Congratulations!<< the mysterious text read on Zack Maldonado’s phone. >>You’ve been cursed by User5932<< Seated on the toilet, Zack stared at the screen, annoyed. What the fuck was this all about? There was a pause and then the phone dinged with another message. >>For a cure, Venmo $1,000 within the next ten minutes to this account or convince the next guy you meet fuck you up the ass. Failure to do so will result in unfortunate and irreversible effects.<<

“Haha, whatever,” Zack muttered to himself. “Must be one of the guys’ idea of a stupid joke.” He deleted the message and, shaking his head, flushed the toilet. 

He’d just pushed himself up off the toilet when there was a knock at the door. “Hey, Zack!” a cracking adolescent voice called through the door. “Are ya fuckin’ done yet? I gotta piss!”

Zack sighed. It was fucking Kobe. He was already regretting his decision to let his housemate, Clarence, invite his kid brother, Kobe, to stay with them for the first week of classes. Clarence and Kobe’s parents were on vacation and Kobe’s high school classes didn’t start until the day after Labor Day. Clarence had promised that Kobe would stay out of sight but so far the kid had managed to insert himself into just about every activity. It was seriously crimping Zack’s style, especially when it came to alcohol consumption. Already they’d been forced to postpone their annual back-to-school bash because Clarence’s parents wouldn’t allow any booze in the house while Kobe was there.

If it were only enforced beer abstinence, Zack would’ve been able to cope with having Kobe around. The problem was the kid’s attitude: He acted like he fucking owned the place. The way Kobe swaggered around the house galled him to no end. Worse, Kobe had singled Zack out for special attention, doing everything he could to knock him down a peg. Clarence thought it was hilarious but Zack was this close to kicking the shit out of the insolent twerp. The kid’s balls hadn’t even dropped yet for chrissakes! He was ready to send the cocky little fuck back home, parents or no. And another thing–

“Yo, Zacky-boy!” Kobe yelled, pounding on the door. “Let me in or I’ll fuckin’ piss all over the floor and make ya clean it up!”

Zack gritted his teeth, the veins popping out on his forehead. That was the other thing that drove him nuts about Kobe: The little fucker got off on treating him like his personal bitch.

Well, he’d had enough.

Let’s see how the adolescent asshole handled this!

Not bothering to pull up his jeans, Zack opened the door before the very startled teenager. Naked below the waist, his long, fat, porn-star-worthy cock swung between his hairy legs just above his hefty pair of bull balls. Kobe’s mouth fell open for a moment before he recovered and, averting his gaze while pinching his nose, complained, “Ewww, dude! It fuckin’ reeks in here! And fuckin’ put on some clothes! What makes ya think I wanna see yer little pee-pee.”

Zack shrugged, stepping out of his jeans and pulling his t-shirt over his head to toss it on the floor. While Kobe stood there debating whether to enter the bathroom, Zack turned on the hot water in the shower, holding his hand under the spray and waiting for it to warm up. He smirked when he felt Kobe’s eyes on his naked body. Take a good look, little bro, he thought, ‘cuz this is what a real man looks like!

Incredibly vain about his appearance, Zack not only embodied the role of Big Man on Campus, he gloried in it. Standing just under six feet tall, he was broad-shouldered and very muscular from working out for hours at the gym. His body was replete not only with bulging muscles but also a plethora of body hair. With shaggy brown hair, brown eyes and a dark chestnut beard, he could easily have gone into modeling or porn, given his good looks and the giant size of his male appendage. Yeah, Zack Maldonado was the hottest guy on campus and had the pussy scorecard to show for it. Barely a night went by when he wasn’t boning a hot chick…or two…or three…

In contrast, he reminded himself, Kobe was just a scrawny adolescent boy. Tall and gawky, he had a bad complexion and chubby face. He couldn’t weigh more than a hundred thirty pounds soaking wet and lacked any discernible muscle mass. His bony torso swam in his brother’s oversized football jersey and his pants would have fallen down around his ankles if not for his tightly-cinched belt. His curly brown hair was currently covered by a baseball cap slung backwards on his head. Those green eyes–yes, even the uber-hetero Zack noticed them–would have been arresting against the boy’s chestnut skin if not for all of the pimples all over his face.

Given how scrawny he was, Kobe’s macho attitude should have been amusing. Here was a kid still in puberty pretending to be a huge stud! The way he strutted around thrusting out his chin and narrow chest was nothing short of ridiculous. At first, Zack had laughed at him but, when Kobe persisted–and even escalated his antics–Zack’s patience was tested. Even now, the little brat had recovered from the shock of seeing Zack in all his glory and was smirking back at him like he was the inferior one. Him, Zack Maldonado, inferior?! Ha! Dream on, you little shit!

Zack ignored him, turning his back as Kobe unzipped his pants and extracted his little boy dick, preparing to take a piss. The bathroom door was still wide open behind them. This, Zack knew without it ever being verbalized, was a game of chicken. The first guy to show a trace of modesty would be the loser and he wasn’t about to lose. Besides, he had nothing to be ashamed of; he knew he outranked every other guy in the house. None of his housemates could come close to his godlike status both above and below the belt.

Zack showered. When he was done, he was surprised to find Kobe sitting on the toilet seat, watching him.

“Huh?” the kid observed, staring openly at Zack’s cock. “The water must be cold or something.”

Zack scowled, unable to stop himself from looking down. He gave a little start when he realized his long, hefty cock wasn’t nearly as hefty as it should be. It was still long alright but not as girthy as usual. In fact, it looked kind of thin. He reached down and tugged on it, ignoring Kobe’s smirk.

Just then his phone dinged from within the heap of his discarded jeans. He bent over and picked it up, discovering there was another text message from the same number. >>Time’s up! The curse has begun. Better get fucked up the butt soon or you’ll regret it.<<

He stared at the screen, perplexed. Then, struck by a sudden irrational thought, he looked from the phone down to his thinner-than-usual cock and frowned. Could there be a connection…?

“‘Curse’?” Kobe asked, reading Zack’s phone over his shoulder. “And what’s this about needing to get butt-fucked?” He laughed, grabbing his crotch. “It’s yer lucky day, bro. Just so happens I’m into anal. Need yer pussy pounded by a real man? I have to warn ya, though, it’s gonna hurt!”

When he reached out and brazenly squeezed Zack’s ass, Zack nearly lost his shit. “Get THE FUCK out of here now!” he yelled, slapping the kid’s hand away and pointing at the door. 

Kobe was undeterred. “You sure, bro? I can really pop yer buzzer with my big ol’ fat cock,” he goaded, dropping his thumbs into his belt loops. Was it Zack’s imagination or was there a noticeable (and growing) bulge in there? When he looked back up, he was startled to see that Kobe didn’t appear quite as scrawny as before. It was probably just his imagination but the kid’s boney torso seemed to have gained some padding. The bumps and ridges of new muscles were outlined beneath the fabric. Oh, they were small but nonetheless noticeable. And his arms…his arms weren’t quite as sticklike as he remembered. But…that wasn’t possible, was it?

“Like what ya see, bitch?”

Zack swallowed hard before recovering his manhood and shoving the boy away from him. “Get lost!” he ordered. “How many times do I have to tell you?”

Kobe stepped boldly closer and Zack looked up, surprised. Was Kobe taller? Feeling lightheaded, he windmilled his arms, falling back against the sink. Why did the room feel like it was spinning? When he looked down at his crotch, he gave a start of shock; his former masterpiece was now decidedly scrawny. Just as long as ever, it dangled more than seven inches down over his furry balls. His circumcised cockhead was unchanged, fat and shiny and round. 

But his shaft was so slender that it made his big glans look disproportionately large. 

Kobe noticed it, too. “Haha! You got a pencil dick, bro! A pencil with a big ‘eraser’!”

Zack was too busy panicking to pay much attention. What the fuck was going on? He settled his bare butt against the sink and took a few deep breaths, squirming around on the cold marble. Why did it feel like he had a couple of big cushions back there? With shaking hands, he reached back and felt himself back there, letting out an inadvertent yelp of surprise when realized he wasn’t imagining it: His ass was definitely bigger!

“Eyes up here, bro.”

He looked up to find Kobe staring at him with barely concealed amusement. Amusement and…another emotion that made his blood run cold. Zack shivered and did a double take when he realized that Kobe’s acne had disappeared. His face was fuller, stronger, more angular. More mature. Were his cheeks stubbly? The boy no longer looked like a pimply-faced fifteen year old. Now he could pass for eighteen easily.

When Zacks’ eyes dropped downward, he saw a few curly, brown hairs emerging from the collar of Kobe’s jersey. His shoulders seemed to widen even as Zack watched. His arms followed suit, expanding and bulging with new muscles. His pecs pushed outward against the mesh and his nipples protruded noticeably. Zack’s eyes lowered and he gaped at the boy’s jeans. Just like his jersey, they were getting tighter, too. And that bulge…Fuck, the outline of Kobe’s cock was clearly visible, shoved hard against the crotch of his jeans. It wasn’t huge but it was definitely bigger than boy-sized. And quite thick, too.

“Lemme fuck yer big, fat ass.”

Zack jerked, belatedly realizing he was naked and alone with a now very turned-on Kobe. A much more grown-up Kobe. His brain couldn’t conceive of how it was possible but the boy now appeared to be only a couple years younger than he was.

Squealing like a little girl, he pushed past Kobe and grabbed his boxers off the floor. He jumped into them, fighting to pull them up his thick legs.

He couldn’t get them over his big ass.

Worse, he couldn’t get them over his long, dangling dick…which was even skinnier than a minute ago. Barely as big around as his index finger, it was almost laughably slender. So skinny that it made his fat cockhead look ungainly. 

Zack goggled. He’d never seen a penis like this! It was so ugly! And so skinny!

“Mushroom stalk,” Kobe pronounced, laughing. His voice sounded deeper and more resonant in his bigger chest. Like a man’s voice. “You got a fuckin’ mushroom stalk for a pecker!”

“SHUT UP!” Zack yelled, hating how weak his voice sounded in comparison to Kobe’s manly one. 

He had no idea what the fuck was happening to him or how to stop it. At that moment, though, the only thing he could think of was getting away from Kobe. The fucking kid was not helping!

Jumping up and down desperately, he finally managed to squeeze his huge cheeks inside his boxers. They seemed to swell even larger as he did so and he felt an ominous ripping sensation in back as the overstretched fabric started to give way. He looked back at himself, whimpering in confusion when he saw how big his butt was. His buttocks jutted out behind him like ripe melons, bouncing and jiggling with every movement. Zack withered with humiliation when he realized they didn’t even look real. Anyone who saw his ass now would think he’d gotten implants.

Big implants.

He didn’t have time to dwell on his ass, though. He penis had continued its inexplicable tapering. Still hanging out of the top of his boxers, it looked absolutely ridiculous. His formerly girthy fuckstick was literally pencil thin. A long, droopy pencil. With an oversized knob swinging at the end.

“That pathetic little clit can’t even get hard!” Kobe teased. “Watch out, bro, or it’s gonna fall right off!”

Zack was so paralyzed with horror that he barely heard. He stared, mouth hanging open, at his once proud manhood, reduced ignominiously to a filament with a huge door knob dangling on the end! Tears filled his eyes as he watched it dwindle even further, going from pencil-thin to straw-thin. His huge glans now looked like an apple tied to a piece of spaghetti! 

Kobe’s deep, guttural laughter filled the bathroom, making Zack’s ears turn red and tears fill his eyes. Belatedly, he woke up to the fact that the bathroom door was still wide open. He had to get out of there! 

Unfortunately for him, he waited a few seconds too long. When he finally managed to goad himself into action and tried to stuff the pendulous thread of his cock back into his boxers, the unthinkable happened.

It fell off.

His cockhead fucking fell right off!!!

He gaped.

What the fuck!?

WHAT THE FUCK???!!!

How THE FUCK could this happen?

He stared in horror as his enormous cockhead detached itself from the winnowing noodle of his shaft and fell with a thud onto the tiled floor at his feet. It wobbled there for a moment before rolling off the side, finally coming to rest against the basin of the toilet. The ‘noodle’ wasn’t far behind, breaking off from Zack’s crotch and drifting down to the floor like a wisp of hair. Before it even landed, it had completely disappeared.

Zack’s cock was gone!

He gaped down at his empty pubes. There was only a small indentation where his penis used to be and that was quickly swallowed by his curly pubic hair. In a second, he blinked in astonishment.

He was cockless.

Completely cockless!

“Whoa, tough luck!” Kobe crowed, clapping him hard on the back. “Yer nuthin’ but a dickless wonder now! Good thing ya get that big, fuckable ass to make up for it.”

Zack didn’t reply. He couldn’t! All he could do was stare at the round ball of flesh at his feet. It was all that was left of his manhood, lolling against the toilet. Kobe was right: He’d been fucking neutered!

Wiping tears out of his eyes, he shoved Kobe aside and staggered out of the bathroom. His big, mutant buttocks sloshed heavily from side to side behind him, all but unbalancing him as he lurched awkwardly up the stairs. Reaching his bedroom, he threw the door open and stumbled inside, collapsing facedown on his bed.

He lay there, openly sobbing, feeling his butt grow bigger by the second. The increasing weight and heft of his buttocks pushed down on him, smothering him. Beneath him, he could feel the empty space that his big cock should have filled. Between the growing weight of his butt and the empty void of his missing cock, he was pushed to the verge of hysterics. This was a nightmare! It had to be just a fucking nightmare because there was no way this could be happening in real life!

He cried for a long time, drowning in self pity and horror, until a sudden sensation broke through the choking haze. He moaned loudly again but this time it wasn’t a moan of despair; it was a moan of inadvertent pleasure.

The sensation came again and he moaned louder, squirming on the bed. If he’d still had a cock, it would have gotten hard. Instead, he could feel the remnants of erectile tissue in his taint swell, pushing his legs apart. He moaned again.

What was this feeling?

Oh, fuck! Oh, god! It felt so good!

It was like getting the most amazing–

He braced, clenching his mutant buttocks when he realized what it felt like.

It was like getting the most amazing blowjob ever.

But…how?

He didn’t have a cock–

“UNGH!”

He writhed on the bed when the sensation came again. The pleasure was so overwhelming that he was unable to stop from reaching down and rubbing the empty hole where his cock used to be. He half-hoped that the weird, erotic sensations meant that his big horsecock was back, just as long and fat as ever.

But there was nothing there.

Moaning and squirming, his poor brain tried to understand what was going on. How could he be getting a mind-bending blowjob when he had no cock? Yeah, no cock whatsoever. Nothing. His fingers were busy confirming what he already knew: There was only an indentation where his huge cock used to be.

“OH, FUCK! FUCK! FUCK FUCK FUCK!”

Zack lost it. 

He orgasmed, empty crotch spasming and big balls churning as jizz erupted from the tiny hole where his urethra now exited his body. He flipped over onto his monstrously big buttocks, teetering back and forth like a kid riding a rocking horse. In the throes of passion, his boxers gave way, ripping off his body. His head tilted down onto the pillows and his legs lifted off the bed. His big butt was like a giant, soft fulcrum beneath him. He grimaced and a little jet of cum squirted up from his empty crotch, arcing upward before landing with a splat on his hairy tummy. He squeezed his eyes shut, unable to watch. It was too much like those videos he’d seen of female orgasm where pussy juice suddenly squirted out of the girl’s cunt.

The phantom blowjob continued unabated. He screamed and writhed, feeling his nonexistent cockhead titillated until he was on the verge of insanity. It was like the softest, silkiest tongue was licking him, tracing the circumference of his big glans. Just when he thought it was over, he’d clench and moan, spewing more jizz, as the invisible mouth closed around him and sucked.

It was the most delirious and exquisite sensation that he’d ever experienced and the irony wasn’t lost on him that it was happening only now that he was completely dickless.

But how? How was this possible?

As if in answer to this question, someone cleared his throat from the bedroom door. Zack rocked up on his mounded buttocks, sweaty and breathless, to find Kobe grinning at him.

Wait, was that really Kobe?

Holy fuck!

The kid had changed.

Completely naked except for a jockstrap that barely concealed his massive, throbbing organ, the ‘boy’ now towered at least six and half feet tall. His toned, lean body was ridiculously ripped and stacked with muscles. His nutmeg-cinnamon skin glistened beneath a liberal coating of black body hair. A ladder of abdominal muscles rose up from his svelte waist, reaching to the most perfect, ripe, round pectorals that Zack had ever seen. Kobe’s shoulders were so broad he almost had to turn sideways to fit through the door frame.

And his face.

Fuck, little Kobe was handsome!

With thick stubble coating his cheeks and a perfect complexion, his green eyes sparkled with both desire and mischief. His tight curls accentuated the ruggedness of his face. His full, succulent lips were drawn upward in a smirking grin. He appeared to be a man of about twenty-five years of age, a man at his peak of physical and sexual prowess.

Zack squirmed uncomfortably, rocking up and down on his giant mounds, feeling long-buried emotions wash over him. Emotions that made him clench and throb and brought him closer to yet another explosive orgasm.

As he stared helplessly up at Kobe, the full-grown man’s grin widened and he opened his mouth, lowering his head to spit something into his palm. Holding it up so that Zack could see, he stated, “Yer knob, bro. You forgot yer knob.”

Zack gaped.

It was his cockhead!

Kobe laughed at his reaction, rolling the slobbery button of flesh around in his palm. Zack’s eyes rolled back in his head. Even though his cockhead was no longer attached to his body, he could still feel everything. Everything. And the sensation of his delicate glans rubbing against the calluses of Kobe’s hand were enough to make him erupt in a violent orgasm yet again.

“St-st-stop!” he pleaded, writhing on the bed and panting after the orgasm subsided. “Wh-wh-what are you doing to me?”

Kobe chuckled. “I’m cursing ya, bro. Who you think sent those texts, huh?” He jabbed his thumb at his mounded chest, grinning. “Me. I made ya my bitch. And now I’m gonna fuck ya. Just like the little pussy bitch you are!”

He tossed the oblong ball of Zack’s cockhead onto the bed. It rolled across the sheets, coming to rest next to his bare thigh. Zack instinctively grabbed it. The knob of softly pulsing flesh was warm to the touch. As if it was still very much alive. Yeah, it was his. He recognized the long piss slit dividing the full mound of the glans. It kind of looked like a plum or a small peach except for the thick ridge around the edge. Turning it over, he saw there was only a puckered scar where it used to attach to his thick shaft. His heart twisted at the sight and a tear rolled down his cheek.

Angry, he forced the tears away.

How the fuck was this possible? He shook his head. How the fuck was any of this possible?

Sweat dripped down his face, plastering his shaggy hair against his forehead. His torso was drenched in sweat as well and he could feel droplets trickling down his massive ass cheeks. They were throbbing beneath him. And still growing. He whined when he felt his ass swell even bigger, pushing him another inch off the bed.

He ignored his swelling ass and poked a finger at his disembodied cockhead.

Nothing.

He felt nothing.

But just a moment ago, he’d felt everything. Every ridge and line and callous on Kobe’s palm.

“Ha! It only responds to me, you dumb bitch.” Kobe swaggered into the room, leaning over him and snatching the cockhead out of his hand. “That’s part of the curse. You can only cum when I make ya.” His handsome face twisted into a sadistic grin as he stuck out his tongue and, holding Zack’s severed cockhead close, licked it slowly.

Zack gritted his teeth but the pleasure was too much to bear. After a few seconds, he couldn’t fight any longer and he threw open his mouth and hollered in ecstasy. It was the most electric sensation he’d ever experienced. It was pure sex. Pure and dirty sex. The best kind.

“So, bro?” Kobe called out in a singsong voice. “Ya ready?” He lowered his hands to the waistband of his jockstrap, pulling it down to expose his kinky black pubes and the base of a cock that was unbelievably thick. Zack gaped. That cock! It couldn’t possibly be real!

His ass clenched at the sight of that monster. He wasn’t gay! And, even if he were, there’s no way he could take a cock that big!

“Well?”

Zack looked up at Kobe and did a double take.

Kobe had aged.

He was probably a few years older than moments ago and now appeared to be nearing thirty.

And that wasn’t all.

His formerly glorious physique wasn’t quite as glorious as it had been. It was still very impressive but he wasn’t quite as cut as before.

Was that a little beer belly?

What had happened to his abs? They were there but fainter.

And were those love handles bulging out over the distinctly tighter waistband of his jockstrap?

Kobe’s thighs had thickened, too. Not by a lot but enough that Zack noticed.

And his face was ever so slightly rounder.

His neck had widened.

His pecs pushed outward, growing even larger.

In fact, all of his muscles were growing bigger…even as they were covered by a new layer of padding.

Kobe still looked like a total beast and was as handsome as ever…just less godlike. More of a young dad than a young adonis.

Zack felt his taint swell between his legs. To his confusion, he grew hot with unexpected desire. Unbidden, a long-suppressed memory from varsity football came back to him. It had happened years ago and he’d pushed it out of his mind. His denial had been so effective that he had nearly forgotten the experience. Now, though, the sight of Kobe’s thickening waistline, huge muscles and even huger cock brought it all back with a vengeance.

Five years prior…

The high school football coach, Syd Thomas, was a new father who had just moved to town with his family. He’d played football in college and took an instant liking to Zack. On that particular day they were alone after practice, naked in the showers. It was the first time this had happened. Showering together was Coach Thomas’ suggestion. Zack didn’t refuse. He stripped and showered, not moving away when the coach picked the shower next to him. Zack knew this was unusual but he just kept showering. He didn’t even pull away when Coach Thomas reached out and ran his callused hand down Zack’s back, resting it on his bare buttocks. He squeezed. 

The message was clear. 

Zack looked over and swallowed when he saw the coach completely naked. He felt a host of forbidden things when he beheld that big, man-sized body. The coach’s burgeoning muscles were covered by thick, black hair and a soft layer of fat. He was so strong, so manly. Zack felt safe when he was with him. He felt protected. Even more, he felt desired. 

His cock rocketed to attention.

Zack shivered, embarrassed. This wasn’t what should happen! He was straight! Coach Thomas was straight! The man had a wife and a child! He forced these unwelcome feelings away and covered his erection, forcing himself to move away. He stalked out of the showers but not before he looked over his shoulder and caught Coach Thomas staring at his full, perky peach. The coach’s huge cock was swollen to a truly astounding size and bobbed alluringly between his thick, hairy thighs. 

Heart pounding, the young Zack found himself smiling. And then he got down onto his hands and knees and offered that full, ripe peach to his coach…

Back in the present, Kobe’s belly swelled almost imperceptibly, pushing out and over the waistband of his jock and bringing Zack out of his hazy reverie. Kobe’s new belly was still relatively small but nonetheless pretty obvious. His love handles thickened, sagging outward and erasing more of his perfect V-shape. The pouch of his beleaguered jockstrap throbbed and pushed outward as well.

Zack licked his lips.

Kobe’s cock had just grown bigger.

Judging from the immense outline, it was at least as big as Coach Thomas’ girthy fuckstick. Zack clenched his butthole, remembering how he’d screamed when Coach Thomas thrust inside him. He’d left him permanently gaping. To this day, Zack had to be careful not to shit himself when he–

“What the fuck?!” Kobe groaned. He was looking down at himself, taking note of his increasing girth around the middle. “That ain’t ‘sposed to happen!” He sucked in his gut but it was no use. His round belly still pushed out before him. “I ain’t ‘sposed to get fat! That ain’t part of the deal!”

Beneath him, Zack felt his buttocks expand still more. They were now a couple of big, soft pillows beneath him, far larger than should be possible on a man his size. He knew he looked like a total freak.

“You said it’s a curse,” he gasped, crotch throbbing despite his complete lack of a cock. “Maybe you cursed yourself, too? Maybe it won’t stop until we–?”

“What? Until I fuck you?”

Zack nodded, breathless. He knew he should be furious at Kobe for cursing him and taking away his cock and giving him an enormous ass that kept growing bigger by the second. He should be paralyzed with self-loathing and horror. He shouldn’t be turned on. He shouldn’t–

But he wasn’t. He wasn’t angry. He didn’t even hate Kobe. How could he? Kobe was rapidly becoming Zack’s perfect man. 

Kobe was becoming Coach Thomas.

Make that an even hotter Coach Thomas. 

And an even hung-er Coach Thomas.

As if to underscore this, Kobe’s giant cock thrust out further, stretching the mesh of the jock’s pouch to near transparency. Kobe had a truly king-sized cock lurking in there and Zack was ready for it. He felt his asshole gape at the muscle memory of being fucked by Coach Thomas.

He wanted that cock inside him.

He reached out and grabbed Kobe by the waistband of his jock, yanking him onto the bed. “Here,” he ordered. “Get behind me. I’m gonna give you my ass to fuck.” Kobe stared at him, uncomprehending. It was as if all of his bravado had evaporated. He couldn’t stop staring down at himself, mouth hanging open in disbelief. Zack noticed that he’d aged another few years and now appeared to be in his early thirties. His belly had grown, too, expanding by a few inches and taking his narrow hips with it. Kobe was now decidedly stocky. He looked like a football linebacker.

A very sexy football linebacker.

Zack took charge, instructing Kobe on every detail. He soon had the catatonic man seated on his haunches behind him on the bed. Zack worked the overstretched waistband of Kobe’s jockstrap down his thick, furry thighs, gasping in shock when that massive cock sprang free. More than a foot long and as big as a tree stump, it jutted out before him. Precum dribbled out from within the folds of his long, tapering foreskin. 

This was new territory for Zack; Coach Thomas had been circumcised like him. He’d never seen an uncut cock up close. But, fuck, was it hot! That glorious, uncut cock was the biggest that Zack had ever seen and it filled him both with fear and desire. Could he really take that up his ass?

“What do I do?”

Kobe sounded like a lost child even though his deep baritone was anything but childlike. Zack realized that, despite his size and weight, Kobe was still an adolescent boy…and a virgin at that. He liked to talk tough and strut around like a confident rooster but it was all an act. If Zack wanted his ass to stop growing–and perhaps have a chance at undoing the curse and getting his precious manhood back–he’d have to walk Kobe through this, step by step.

He wobbled precariously on his inflated buttocks, rolling over to rummage through his bedside stand and extract a condom. “Here,” he said, holding it out. “Put this on.” 

When Kobe merely gaped back at him blankly, he sighed. He tore open the packaging and pulled out the condom, glad it was extra large and therefore big enough to (barely) fit over Kobe’s giant cockhead. He was about to work the condom onto the guy’s pulsating shaft when he was struck by sudden inspiration.

Taking the amputated knob of his cockhead out of Kobe’s hand, he peeled open that generous foreskin and thrust it inside. His whole body went rigid with pleasure when he felt his cockhead meet Kobe’s. The two cockheads were now ‘kissing’ in the confines of Kobe’s foreskin. 

Reverberating with blissful excitement, Zack cinched Kobe’s foreskin shut and slid the condom down over his shaft. When he was done, his disembodied knob was firmly lodged against Kobe’s and held in place by the condom. He couldn’t stop trembling with eagerness when he imagined what it would feel like when Kobe…

“I’m so fat!” Kobe wailed.

Zack looked up and felt his taint thrum with desire when Kobe’s entire body widened and thickened. His shoulders thrust outward, the deltoids swelling to the size of bowling balls. His pecs were even bigger and heavier, sagging so much his big nipples pointed down at the bed. His muscle gut expanded, lifting up and pushing out before hanging down over his crotch. While still very muscular, Kobe was also now decidedly heavy. He’d gone from stocky to husky in less than a minute.

And he was older, too. He now looked like he was well into his mid-thirties.

Zack’s eyebrows lifted when he saw the first white hairs appear on the boy’s chin. Like the rest of his body, his handsome face was heavier and thicker than before, definitely the face of a mature man. A mature daddy!

“Here,” Zack ordered, rolling up on his giant buttocks to take Kobe’s face in his hands, “forget what you look like and fuck me.” He rolled back down onto his back and spread his legs, opening up his hairy taint and exposing his gaping butthole. Almost hidden by the forest of his butt hair and his swelling buttocks, it was still visible. Kobe’s eyes lit up when he saw it and his mouth opened. His tongue lolled out.

Zack had unwittingly chosen the perfect position to get fucked. If he’d been on his hands and knees, his massive butt cheeks would have gotten in the way and even Kobe’s long cock couldn’t have scored his asshole. Lying on his back, though, with his legs in the air, the ‘boy’ had ready access to his pucker. Zack reached back and winced in self-loathing as he grabbed his mutant ass cheeks. He didn’t let his disgust stop him, though. He pulled them back and relaxed, offering his asshole to the ardently aroused man before him.

Instinct took over. Kobe spit into his palm and slicked up his cock, leaning forward and aiming for Zack’s open hole. There was a long, perilous moment during which Zack felt his own cockhead–still held firmly inside Kobe’s foreskin by the condom–pressed against his own pucker. He gasped, eyes rolling back in his head. The sensation was as incendiary as it was impossible!

And then Kobe was in.

Zack moaned, partly in pain and partly in delirium, as Kobe’s cock forced its way inside. His sinews stretched and at least a couple tore but generally his hole held its own against such a voracious onslaught. Coach Thomas had prepared him well and his asshole had never forgotten the older man’s lessons. It knew how to stretch and give way to accommodate a truly man-sized cock.

All that was good but it was the sensation of his own cockhead thrust deep inside his own chute while getting pummeled by Kobe’s hard, throbbing glans that really overwhelmed his nervous system. When Kobe scored his prostate, Zack nearly passed out. 

The combination of his disembodied cockhead sandwiched between his prostate and Kobe’s cock was too much. He lost it for the fourth time, cum spewing out from his little pee hole. Kobe laughed, lowering his head and lapping it up.

Kobe fucked him over and over and over, not stopping until Zack begged him to. Zack was worn out, his asshole slack and tender from being stretched to oblivion. He’d cum more than a dozen times, each time with Kobe finding some new way to torment him with his own cockhead. When the ‘boy’ stuck that cockhead up his own, virgin butthole (after applying lots of lube), Zack enjoyed the unbelievable pleasure of having his cockhead buried in another man’s asshole while that man’s giant cock was buried inside his own asshole.

He couldn’t take it anymore.

He was completely spent.

By the time they were done, Kobe weighed more than three hundred pounds and had aged into his forties. Zack’s buttocks were so swollen that he didn’t own a single piece of clothing big enough to cover them. They stuck out behind him impossibly far, a perky shelf of a perfect boy butt. Perfect gay boy butt, that is. For the rest of his life, everyone who saw him knew immediately that only a slutty gay man could possess an ass that huge.

“Yer such a little slut. Yer daddy’s little whore.” 

His eyelids fluttered open and he found Kobe staring affectionately down at him. Zack opened his mouth. He had a vivid memory of Coach Thomas saying those exact words; he’d always call Zack his little whore after he fucked him. “Th-that’s what…I mean, how did you–?”

Kobe grinned. “Clarence recorded you and the coach fucking. He still has the videos.”

Zack’s chest clenched. “What?! You mean–?”

“Yeah, Clarence knows yer nuthin’ but a stupid little gay slut, too.” He chuckled, reaching absently down to pat his protruding belly; it was big and round and yet strangely still quite muscular. It was, Zack decided, the sexiest dad belly imaginable. 

“And now yer my stupid little gay slut.” Kobe moved his hand behind himself and, grunting for a moment, squirted Zack’s cockhead out of his man ass. He held it up to Zack’s face, pinching it between his thumb and forefinger. It was still covered in lube and…well, other stuff.  Zack’s nose wrinkled and Kobe laughed. “What? Dontcha wanna lick it?” He grinned at Zack’s horrified reaction and then totally grossed him out by popping it into his mouth.

He didn’t have long to dwell on how disgusting this was because Kobe’s tongue was already working its wonders on his severed cockhead. Soon, Zack’s eyes were rolling back into his head for the thousandth time that night. Kobe fucked him hard and good one last time before he finally collapsed on the bed next to him. Forcing Zack’s body against his own, he folded his great, furry body around him and fell asleep. 

His monster cock was still buried deep in Zack’s hole. And so was his own cockhead. Kobe had thrust it in there just before he came the last time. He could feel the tip of Kobe’s still-hard cock tickling it and his own hot, gooey chute enveloping it. Zack turned his head to look at the sleeping man’s face. Kobe was almost unrecognizable from the pimply, scrawny boy of hours ago. So big. So fat. So handsome. So mature.

The big man was the complete contrast to him. He looked down at his neutered crotch, completely inferior and penis-free. His useless bull-balls lolled on the bed beside him, making his dicklessness even more obvious. Behind him, his immensely fat buttocks pillowed against Kobe’s fat belly.

He sighed and smiled despite himself.

He was nothing but daddy’s little whore.
