Accidentally transforming my boyfriend into my football coach

John and Aaron had been dating for a little over a year. The men had met in their freshman year of college during football tryouts and had become fast friends. Over the following years, their friendship had gradually deepened and become something more, much to their surprise. Neither of them had ever been with a guy before but were unable to deny the chemistry between them, eventually giving into their desires after a late night gym session. Though neither of them were ashamed of their relationship, they had kept it a secret as they'd been afraid of how the rest of the team and their Coach would react.

The two would often linger in the locker room after football practice, waiting for the rest of the team to head out. When they were finally alone, they would press their muscled bodies against one another for a makeout session. They had mutually agreed to take things slow, both men inexperienced at gay sex and unsure of what position they would be. Lately, their hookup sessions had escalated to sucking and jerking eachother off.

One night, as their last teammate left the change room after practice, John approached Aaron with an unusual request.

"Would you mind wearing this?" John asked Aaron, unzipping his backpack and retrieving a pair of black boxers.

"Uh...yeah, I guess I could," Aaron replied, reaching out and taking the jockstrap from John's grasp, "Why?"

"Truth be told, I swiped it off of Coach Ryerson, and I kind of have a huge crush on the man," John admitted, blushing as he looked down at the floor in embarrassment. "I thought it would kind of be hot if you wore it and we roleplayed as if you were Coach or something. It sounds kind of stupid now that I've said it out loud."

"It doesn't sound stupid; I'm just surprised. I didn't know you were into roleplay," Aaron winked playfully. He slid down his football trousers and jock, revealing his hardening 6-inch cock. Aaron kicked off his cleats and slid the boxers up his legs and over his genitals. The boxers were a little baggy on him, loosely hanging around his waist.

"Damn, babe," John growled in arousal, tossing off Aaron's football jersey so he was wearing nothing but the ill-fitting boxers.

"I guess Coach and I aren't the same size," Aaron observed with a laugh, looking down at his toned, muscular body and the oversized boxers he was wearing.

"Just relax, you look good," John whispered, gently pushing Aaron up against the lockers and giving him a passionate kiss. John's jersey and trousers quickly came off, leaving him in a pair of tight white compression shorts.

The men continued to kiss and thrust up against each other, lost in the throes of lust. Aaron felt a sudden surge of power flow through him, originating from the boxers. His crotch started to tingle, the electric feeling quickly spreading out through his torso and limbs. He let out a small involuntary moan in pleasure from the sensation.

"You okay, baby?" John asked in concern, pulling back from their embrace; he could feel Aaron's body tensing up.

"Yeah, I'm feeling fucking fantastic," Aaron grinned, spinning John around and slamming him against the lockers. John was a little surprised at Aaron's sudden aggression; usually he was gentle and slow during their romantic encounters. John was almost sure that Aaron's shoulders were a bit broader than usual, though he assumed his eyes were playing tricks on him.

As Aaron continued to thrust up against John, he started to grow taller. Aaron had been a few inches shorter than John, but was now taller than his boyfriend by nearly half a foot. His already impressive quads legs began to bulk up and thicken with muscle, while his feet expanded from a size 9 to 11, thick dark hairs sprouting from his toes.

John had noticed the changes and was filled with panic, pushing Aaron away from him. He watched as his boyfriend continued to transform, feeling a mixture of fascination and horror.

"What's happening to you, babe?" John asked, his voice quivering.

"I don't know... but it feels so fucking good," Aaron moaned, his voice deepening as his adam's apple grew more prominent in his throat.

Aaron's pecs ballooned up with muscle while also gaining some fat, his previously tight pectorals now drooping slightly over his abs. Speaking of which, Aaron's washboard abs smoothed over as he packed on some additional weight around his midsection, bulging into a small round belly. Aaron’s shoulders broadened, his arms inflating with thick muscle, his tendons and ligaments developing. His toned biceps and triceps grew even larger. Thick dark brown hairs grew across Aaron's entire body; he went from smooth to hairy in a matter of seconds.

Aaron reached a hand down and stroked his cock through the boxers as it grew longer and nearly doubled in thickness. His balls dropped lower as they also expanded, filling with semen. His tight firm ass rounded out, plumping with fat and muscle.

Aaron's stylish light blonde hair shortened into a crew cut, darkening to salt and pepper. His jawline grew more pronounced, a well trimmed beard forming along his chin and lips. His facial features began to age rapidly, wrinkles appearing as Aaron went from his early 20s to mid 40s. John couldn't believe his eyes; his boyfriend had changed into a completely different person right in front of him. Standing in front of John in nothing other than tight boxers and sporting a rock hard cock was his football coach, Coach Ryerson.

John stared at Coach Ryerson in disbelief. The boxers that had been loose on Aaron were now skintight on Ryerson, showing the outline of his 11 inch cock. Coach Ryerson grinned at John as he continued to stroke his shaft through the boxers; John found it difficult to tear his gaze away from Coach, feeling almost mesmerized by him.

"What...what the hell is going on?" John asked, slowly backing away from his Coach. Ryerson was standing between him and the exit, making an escape difficult.

"I'm assuming you swiped this from my gym bag?" Ryerson asked, gesturing towards the boxers he was wearing. Reluctantly, John nodded in affirmation. "I've had three pairs of underwear go missing in the past month from my office," Coach explained. "I knew that someone must have been stealing them, but they were impossible to catch. Luckily my husband is a bit of a wizard, and he offered to put a spell on my boxers. He promised that the next time it was stolen, I would be able to identify the culprit. I didn't realize that this was what he had in mind, but it's more creative of a punishment than I could've thought up," Ryerson laughed, glancing downwards and checking out his own body.

"It's not fair for you to punish Aaron; he was only doing what I asked!" John protested. "I was the one who actually stole it."

"Maybe you're right. I suppose you deserve to be punished, as well," Ryerson agrees with a wicked grin.

Ryerson grabbed the rim of the boxers and slowly slid it downwards, exposing his hard dick and balls. He stepped out of the underwear so he was now completely nude, holding the boxers in his hand while he maliciously approached John. John's fantasy of having an intimate encounter with his Coach was coming true, John realized; it was just not exactly what he'd had in mind.

Curse of the Twink

Bobby ran a hand through his styled hair as he entered the bar, scanning the room for a potential victim. He hadn't fed in a week and could feel his cock pulsing within his briefs, begging to drain a stud of his muscles and manliness. He quickly took notice of Broden, a muscular jock loitering near the bar counter.

"Hey there," Bobby called out in greeting, approaching Broden with a friendly smile. "Mind if I join you?"

Broden looked up from his drink, his eyes lighting up as he appraised the slim twink flirting with him. "Sure thing, little guy."

Bobby slid onto the barstool next to Broden, signaling to the bartender for a drink. His delicate, manicured fingers gently brushed along Broden's muscled thigh through his blue jeans. "So, what brings you here tonight?"

Broden chuckled, taking a swig from his beer bottle. "Just looking for some company to kill a couple of hours. You?"

"Same," Bobby replied, leaning in and whispering in Broden's ear, "How about you show me your apartment?"

Broden smirked, nodding in agreement. "Sure thing, cutie."

Bobby slid his hand into Broden's and lead him out of the bar, leaving their half finished drinks behind. Bobby could feel Broden's eyes fixed on his tight round ass and purposely wiggled his hips so it bounced with every step. Bobby wanted to feast on this jock and drain his masculinity right there in front of the entire bar, barely able to control his urges.

Luckily for Bobby, Broden only lived a few blocks away from the bar. The men walked through the cool autumn night in silence, both thinking about what would happen once they made it back to Broden's apartment.

Once inside, Broden slammed the door shut behind them before he pushed Bobby against the wall, his hands roaming all over Bobby's slender frame. "You sure you know what you're getting into, little fella?"

Bobby moaned softly, wrapping his own arms around Broden's thick waist. "Oh, I'm positive."

Broden's lips brushed against Bobby's, their tongues eagerly massaging one another. Bobby's hands slipped under Broden's tank top, running his palm down Broden's chiselled abs.

"Fuck, you are turning me on so much," Broden growled, grinding his hard member against Bobby's thigh.

Bobby gasped. "Fuck me, Broden. Please."

With a grunt, Broden lifted Bobby effortlessly and carried him to his bedroom. He gently lowered Bobby onto the bed, crawling beside him. "Hope you can handle a big man, baby."

Broden tore open Bobby's shirt, exposing his smooth, flat chest. His mouth grazed against each nipple, sucking and nibbling as Bobby writhed beneath him. Bobby's hands roamed over Broden's muscular back, squeezing his broad shoulders.

"Take off those pants," Broden demanded, his voice rough with desire.

Bobby hurriedly kicked off his jeans and briefs, leaving him naked and vulnerable. Broden stood up, quickly stripping off his own clothes with a frantic fervour. His erection sprang free, long and thick, dripping with precum.

Bobby's breath hitched as he took in the sight. "Holy shit, Broden. You're... huge."

Broden chuckled, positioning himself between Bobby's spread thighs. "Ready, cutie?"

Bobby nodded, his heart pounding throughout his body. "Yes."

Broden lined himself up, pressing the mushroom head of his cock against Bobby's tight hole. With one swift motion, he thrust forward, burying himself balls deep.

Bobby screamed, both in pain and pleasure. "Fuck!"

Broden began to thrust his hips, pulling in and out of Bobby's hole. "That's it, take it like a good boy."

Broden's thick, meaty fingers dug into Bobby's shoulders as he kept up his pace. Each thrust sent shockwaves of ecstasy through him, pushing him closer to the edge.

"Harder," Bobby panted, "Don't stop."

Broden obliged, increasing the intensity of his thrusts. His abs clenched with each pulse, his muscles rippling under his skin.

"Almost there," Broden grunted, his breath coming in ragged gasps. "Gonna make you cum, baby boy."

Bobby came, his body spasming as he coated his own stomach with his release. The sensation pushed Broden over the edge as well, his cock throbbing as he spilled deep inside Bobby.

Both men panted heavily, Broden gently extracting his member from Bobby. Broden collapsed on the bed beside Bobby, his eyes drifting close as he recovered from his orgasm.

Broden felt a strange tingling sensation begin to spread through his body. He looked down in confusion as he saw his abs start to smooth over, the defined ridges softening and filling out into a flat tummy. Broden's muscles began to deflate, his thick and veiny biceps shrinking down to become lean and scrawny. Bobby's heart continued to race as he watched the transformation unfold before his eyes.

"What the hell is happening?" Broden muttered, his voice growing soft and higher-pitched.

Bobby didn't bother responding, too entranced by the spectacle of Broden's changing form. Broden's long and thick cock began to shrink down, shortening and thinning. His balls shriveled, retracting into his body. Broden's ass ballooned out into a tight bubble butt.

Broden's face was the last thing to change. His sharp features softened, his jawline rounding as his masculine visage gave way to a more delicate appearance. Within moments, Broden had transformed into a mirror image of Bobby himself.

"No," Broden whispered, his voice now sounding identical to Bobby's. "This can't be real."

Broden's brain chemistry began to alter, his memories and personality changing. Instead of being the tough macho jock, he now remembered being the shy, quiet outcast throughout most of his life. His memories of topping dozens of twinks were rewritten, replaced with bottoming for various men. He lost any interest in sports or video games, now being interested in fashion, novels and cooking. Broden was completely gone, replaced with an exact clone of Bobby.

Bobby reached out and traced the chin of his clone, admiring his handiwork. Broden had changed just like the others had.

---‐---------------------------------------

Bobby had once been in a long term relationship with a man named Martinez. He had loved Martinez deeply and had been sure they would spend the rest of their lives together...until he'd walked in on Martinez with another man. In the ensuing argument, Martinez had cruelly called Bobby nothing but a 'dumb, easily replaceable twink'.

Heartbroken, Bobby had fled their apartment and wandered the streets in a daze, eventually stumbling into a Magic Shop. Bobby had entered looking for a cure to his sorrow, but the mysterious store clerk had suggested revenge was a much more cathartic solution. The clerk sold Bobby a potion, instructing him to drink it and convince Martinez to have sex with him one last time.

As instructed, Bobby swallowed the potion's contents, plugging his nose so he couldn't taste the bitter liquid. A strange energy pulsed from within him; he hurried back to his apartment. Martinez was more than willing to let Bobby back in as the twink apologized, begging for sex. Martinez wasted no time leading Bobby to their room, stripping down and thrusting his swollen member into Bobby.

After cumming, Martinez had complained about a strange feeling. Bobby watched on in awe as Martinez was slowly drained of his muscles, his beefy body deflating into a thinner, skinny build. Martinez shouted obscenities as his massive erection shrunk down, dwindling to less than half of its former glory. Martinez's golden brown skin lightened to a pale white, his stubble and body hair disappearing back into his skin.

Bobby looked on in awe as Martinez's body continued to shift into a replica of his own. After the change was complete, it was clear that Martinez was gone, replaced with an identical clone of Bobby.

Bobby hadn't meant to change Martinez; he'd had no idea what the magical potion he'd been given would do. Still, as he and his clone curiously inspected each other, he found it difficult to regret his choices. Martinez had been a dumb, brutish jock; sure he'd been hot, but he was also opportunistic and cruel. Having another Bobby in the world seemed like an upgrade in comparison.

The two Bobbys got along great, seeing as they shared all of the same interests and habits. Living with himself was a massive upgrade over Martinez, who had been a messy slob. The only problem, Bobby hated to admit, was that he missed sex. While he found himself attractive, neither Bobby was willing to assume the top position that Martinez had vacated. The Bobbys had kissed and jerked each other off, but as the days passed he had an almost overwhelming urge to be penetrated again.

A little over a week after Martinez's transformation, Bobby could not resist the need any longer. He headed out to a gay bar, looking for a quick hookup to release the tension that had been building in him. It didn't take him long to meet Alistair, a drunken frat bro who was clearly looking for someone to take home.

Without much preamble, Alistair and Bobby headed back to Alistair's apartment. Bobby wanted to avoid his own place as he wasn't sure how he'd explain his clone, should they cross paths.

After Alistair emptied his load inside Bobby, the pent up hunger that had been growing in Bobby quickly subsided. He let out a sigh of relief, feeling at ease once more. Bobby was surprised when Alistair let out an uncomfortable grown and complained about a weird sensation. It didn't take long before Alistair's muscular body shrank down, morphing into a copy of Bobby's.

Bobby had assumed that the potion had been a one time spell and the magic would have worn off after getting his revenge on Martinez. Looking at the jock turned twink before him, Bobby realized this wasn't the case. It appeared that any man that fucked him would succumb to the magic, transforming into a replica of him.

Bobby felt guilt over accidentally transforming Alistair. Where Martinez had had it coming, Bobby had only met Alistair a few minutes before changing him. Bobby vowed to stop sleeping with men, not wanting to spread his curse any further.

A week after hooking up with Alistair, the urges returned. The magic was growing within Bobby, looking for a release; he could barely control himself. The curse wanted to be spread, whether Bobby agreed or not. He tried to distract himself, but with every hour that passed, the struggle got harder. The feeling was primal in nature, an animalistic need that could not be ignored. As it approached midnight, Bobby finally gave in and headed out to the bar where he met Broden.

---‐---------------------------------------

Bobby looked over at his sleeping clone, the one who had been Broden a little over an hour ago. After Broden's change, the new Bobby had been exhausted and quickly fell asleep. Bobby tried to join him, but sleep eluded him as his thoughts raced.

He had now stolen the lives of three men. As guilty as he felt, the knowledge that he had turned these muscular studs into his own possey of Bobbys did have a seductive allure to it. Would the magic ever fade? Or would he continue to sleep with men indefinitely, draining their masculinity and creating more twinks?

Bobby pushed the thoughts from his mind, taking a deep breath to relax. Whatever was to come, he would find a way to deal with it. And he wouldn't have to do it alone, he thought, snuggling into the arms of his twin.
