Coach's Whistle

[Content Warning: Rough Sex]

“Look coach, I’m sorry. Okay? It won’t happen again I swear,” Justin said. He sat in the chair across from his coach. But the apology didn’t seem to do much of anything. His coach just kept a stern glare. “How about I just go and apologize. You can make me run extra laps and then--”

“No,” his coach finally spoke. The large burly man had a way of commanding his presence. “I think I’ve had enough of your apologies. How many times have you told me something like this wouldn’t happen?” Justin sat quietly and massaged the palms of his hands. At least five, but he wasn’t about to say that. “That wasn’t rhetorical!”

The boom in his coach’s voice made Justin jump. “I don’t know! Three?” he lied.

“Three…” Coach sat there and glared even harder. He stared through the other man letting the lie ruminate between them. “You’ve only done this three times.”

“Ye-yes,” Justin cleared his throat trying to sound more confident.

It didn’t work. “Then let’s count them.” Coach pulled out a sheet of paper and put his glasses on. The small squared rims rested at the bottom of his nose, contrasting his slightly rounder face. “There’s the time with the Remaro boy. The time in the lunch room with Martin. The thing you did to Derrick. The time you tried to pick a fight with Officer--”

“Enough! Enough,” Justin shouted. His hands went to his ears as he tried to block out the sound. “I get it. It was more than three. So what? It’s not like any of those are expellable offenses.”

Coach’s mouth thinned to a line. Even through his hefty beard, it could be seen. His eyes narrowed and pointed down. “And why do you think that is?” his voice was low and growling. Justin took the hint. He shut his mouth and pushed himself back as far as he could in his chair. But then Coach didn’t start laying into him. Instead he went to a drawer in his desk and pulled out a whistle. He gave it a blow.

The loud sound filled Justin’s ears. He couldn’t believe how loud it sounded. Yet no one outside the office seemed to take notice. “What was that?” he rubbed his ears. He could almost feel like he could still hear it. The sound seemed to have been still blowing, yet only inside his head.

“This is my special whistle. And it’s going to make you do exactly as I say,” Coach said.

“What? That sounds stupid. Just let me--”

“Oh, just shove it up your ass. You’re going to have to do a lot more than apologize to everyone on this list. I’m not letting you off this easy. No, I’ve been wanting to try this out for a while now…” he blew the whistle again. The sharp sound pierced through Justin’s ears again. “You are going to be a 35 year old football coach in charge here. I’m going to be the 19 year old stud football player. Got it?”

“Huh? Wha--” Justin cut himself off as he felt a weird sensation running through his body. A jolt of electricity seemed to have excited each and everyone of his muscles. He could feel the sensation running through him. “Stu?” he meant to say coach but called him by his first name. Consciously, he knew what he had done, but at the same time couldn’t stop himself from saying anything else.

But that was far from what he was worried about. The sensation in his body only doubled, distracting him from everything else. Looking down at his hands he could see them starting to change. There were a few more wrinkles in them and the skin seemed to dry out. But more importantly they were starting to grow. Thick muscle and fat seemed to be forcing his hands to be bigger than they were before. 

That growth was quickly traveling up his forearm. He could feel the weight and strength starting to add onto it. It went through his bicep, making the muscle gain at least 3 more inches of mass. He’d been saying how he wanted it to be closer to 20 inches now, he just had two more to go. It didn’t seem to bother him that a bit of the extra size was due to fat. The added size just gave him more of a reason to wear sleeveless shirts.

Justin’s shoulders rounded out. His chest pushed out further in front of him. His small nipples seemed to double in size. He could feel their sensitivity as the straps of his sleeveless shirt rubbed up against them. Fat quickly added to his belly. The six pack he’d been trying to gain was instantly lost into one large round belly that stuck out in front of him. His waist doubled in size and his hips pushed against the sides of his seat. 

He tried his best to open his legs to allow his cock and balls some room but the thickness of his thighs seemed to make that a lot harder to do. Justin scratched at his belly as hair sprouted from his skin. The light dusting quickly grew to a dense forest that went all over his body. A thick beard grew around his rounded chin that was several inches deep while the hair on top of his head seemed to disappear. 

Stu let out a laugh. “You’re going to be a great coach.” He crossed the room and looked at his body in the mirror, making sure to flex his young muscles again. The whistle really did follow his order in making him a stud. He couldn’t believe the number it did on him. Firm muscles, a good amount on his chest while a solid six pack was right beneath them, strong arms, a square jaw with just enough hair to make a good beard and then the hair on his head. He couldn’t remember the last time he saw it this thick and covering his whole skull.

Meanwhile Justin was still digesting all the orders he’d just been given. ‘You’re going to be a great coach,’ and ‘shove it up your ass’ were the two that were the hardest for him to understand. Slowly he was coming to the conclusion. To be a great coach he had to have something shoved up his ass. The words wormed deeper into his mind. He couldn’t fight it off anymore. A finger tickled his backside but that wasn’t enough. He could see Stu praising his body.

It was a good body. Strong. Masculine. Alpha. Justin could feel his dick getting hard at what he might have been hiding in his khaki pants. He saw the whistle and put it around his neck. The metal nestled between his thick pecs. “Stu?” Justin used his coach’s voice.

The 19 year old looked at him. He realized that he didn’t have the whistle anymore. “Hey… Coach…” he knew he’d meant to say Justin but Coach came out. “What are you--” A toot of the whistle filled his mind. He could feel the sound fill his mind. Even though he pushed his hands against his ears, he was too late. Not that it would have worked anyways. “Coach… You should put that down.”

“Put it down? No, I can’t do that,” Coach said. “I need a whistle to be a good coach.”

“But you already are a good coach,” Stu said. He was trying to distract Coach to get the whistle. 

“Thank you,” Coach said. “But I need this. It’s going to make me even better.” He blew it again and the sound pierced Stu’s ears. All the student could think about was the sound. And his coach’s voice. “So how do I do this… You want to be a pro football player. You’ve been working at it for as long as you can remember.”

Instantly Stu’s body started to grow. He could feel his muscles molding and changing ever so slightly to build into a more perfect football player’s build. He’d focused mostly on quarterback but could have easily filled in for a few other positions if needed be. Thick muscles filled his entire frame. At 6’2” he was already tall but he grew a few more inches but with the added length he didn’t lose any of his size.

“Coach…” Stu panted. He could feel his past rewriting itself to fit the command. Ever since he’d been able to pick up a football he was throwing it around.

But Coach ignored him. “You have a large dick. One that’s impossible to hide. It’s why you exude ‘big dick energy.’”

Stu felt the growth in his pants. The bulge was almost uncomfortable as it pressed hard against his pants. It dropped out of his underwear and drifted down his right leg. The indent could be clearly seen. “Coach,” Stu said again. He’d managed to move a few steps closer but with his enlarged appendage, it was hard to really focus. 

Again Coach ignored him. “You’re a real alpha when it comes to guys who want to get fucked by you.”

“Coach,” the timbre in Stu’s voice deepened as he stood up straight. Confidence soared through him as he spoke. “You need to give me that whistle. You don’t know what you’re doing.”

“Nonsense,” Coach blew it again. “You love the changes. You want to fuck me right now.” 

Stu’s eyes went wide as he felt the urges push into him. His mind was telling him no, but body screamed yes. Seeing his coach start to run his thick hands threw the pelt of fur across his belly was more than he ever thought it would be. Stu could feel his fears start to melt away as his love of the changes took over more. Each second he could feel his thoughts be invaded by the new reality and forget the old one.

It didn’t help that Coach was turning himself around and dropped his shorts down around his ankles. The fat ass pointed directly at Stu. Stu’s slow massage of his crotch quickly upped in pace. Before he knew it his pants were around his ankles. He stepped closer and grabbed the other man’s wrists and held them behind his back. “You absolute piece of shit. I’m going to make you pay for this.”

A giggle came from his coach as Stu said it. All it did was piss him off more. Stu pulled out his cock and let only a bit of his pre drip on the hole. He pushed hard, opening it quickly. Far faster than it probably should have for his first time. Coach and him let out a grunt for different reasons, but Stu didn’t let up. He pushed again feeling the tight hole wrap around his cock.

His strong hands held the other man tightly. He pressed a bit more weight onto his coach, but it only seemed to encourage the older man. Any amount of discomfort seemed to just turn him on more. “You little fucker. You think you can tell me what to do?” Stu growled. 

Coach let out a loud huff. His body seized up at the insult and he let himself go. The sensation was too much and being called a little fucker felt better than he thought it ever would. Thick wads of cum sprayed against the desk underneath him. The white liquid dripped down the wood finish. 

“Bastard,” Stu gave him a hard slap to the back and kept going at it.

Coach pushed the whistle against his mouth and a toot came out. “Having sex with men is more pleasurable than women because condoms can’t hold how much cum you make.”

“The fuck?” Stu felt his balls lower and filled whatever gaps could have still been between his legs. Suddenly his mind enjoyed the sex even more. He couldn’t hold back and felt them cock and release. “Oh fuck.” It was more of a statement as cum splattered against Coach’s insides. Several thrusts and he was finally finished.

It took a good thirty seconds before Stu was down to a size where he could pull out again. Coach seemed to enjoy the sensation. “Alright asshole. Give me the fucking whistle,” Stu ordered. The alpha order seemed to make him into a bit of an ass.

“Absolutely not,” Coach blew it again. Stu tried to cover his ears again. “You’re a model citizen. You use your strength to help others and when you have sex with someone, you treat them well unless they want it rough. Got it?”

“Got it,” Stu said. “Now can I pl--”

The whistle blew again. “You don’t want the whistle. You enjoy these changes too much to ever want to use it again.”

Stu’s mind started to change. He kept staring at it, wanting it, but at the same time the magic made it impossible. He felt the urge to just grab it but the changes were so good, why would he? “Alright coach,” he finally said. “Guess I’ll see you later.”

“Later,” he gave Stu a wink. Coach watched the soon to be pro athlete leave his office. His attention turned back to the list that his former coach had made. “Guess I have a lot of guys to do a lot more than apologize to everyone on this list…”
