Coach's Whistle Part 02

Coach found a dark blue polo and some khaki pants that fit him perfectly in the closet of his now office. After being turned into the coach, it didn’t seem right to wear the more jock style clothes he’d been wearing. It showed off too much of his hairy bulk. But with the polo and khakis he looked like he had a bit of authority. Even if the clothes fit perfectly around his hefty contours, he felt like it made people notice him more. 

Even as he walked around the campus he could see people turn their heads. Somehow the whistle seemed to have made him the coach at the college and he was going to be the best coach they ever saw. Or course with the whistle nested between his meaty chest, that was going to help out a lot too.

A slight grin appeared on his face as he thought about it a bit more. Though he needed to test it out a little bit before he fully understood what it was capable of doing. Obviously it was very powerful but he needed to make sure he knew what he was doing. He looked up and saw Donny Remaro in the library. 

The small nerdier student had a couple of books open on the desk in front of him. Each one on a different page while he was writing in his notebook. He didn’t even notice Coach come by. “Hey there bud.”

Donny jumped at the sudden interruption. He was so into his notes he hadn’t realized that Coach was there. “Hey?” he questioned. There was a sense that he knew Coach was one of the teachers, yet he didn’t understand how he knew him. Or more why someone like him would want to talk to him.

Coach was happy that he didn’t recognize him as Justin. He didn’t need to be known as the guy who bullied him out of a few weeks of homework. Of course when Stu had found out he was pissed off. But Coach figured none of that had happened now. “You should come with me to the gym.”

“Why?” Donny’s face turned to one of pure disgust. He was not someone who visited gyms. His small lean body clearly never worked out and he wasn’t about to start without some kind of incentive.

Luckily Coach had it. He blew the whistle. Everyone in the area seemed to perk up and stop what they were doing for a second. Slowly they started to come to. “You,” he pointed at Donny. “Come to the gym with me.”

Donny started packing up his books. He looked like he was trying to stop but couldn’t. His body just kept moving on it’s own, pushing in book after book into his bag. “Ok,” he agreed, but wasn’t sure why. When he was done, he slung his backpack over his shoulder and lined up with Coach. “So why do you want me to go to the gym with you..?”

“Coach,” Coach answered as Donny had left the line open.

Another face of disgust flashed onto Donny’s face. “Alright, Coach,” there was a sneer in his voice as he said it, “why do you want me to go to the gym?”

‘Must have a time limit,’ Coach thought to himself. He quickly tooted the whistle again. A few people in the area drew to attention. “Because you want to get big,” he said while they were walking. “It’s why you came to me. You told me in my office, ‘I want to learn how to build muscle and get stronger.’”

“Right…” Donny shook his head a few times, feeling the memories implant into his mind. Something was telling him it was wrong, but there they were. He could vividly see himself standing at the other side of Coach’s desk and asking him for help. How could he have known what the inside of the teacher’s office looked like unless he was there. As was that desire, the desire to get big. 

Coach led him towards the gym. He tooted the whistle. “Go get changed into your gym clothes,” he said as they entered the locker room.

“Gym clothes?” Donny asked.

“The gym clothes in your bag,” Coach answered.

Donny felt the contents of his backpack change slightly as gym clothes were shoved into the bottom of it. “Right…” he agreed, almost confused as to how it happened.But it only made sense if he was planning on going to workout with Coach. 

A grin appeared behind Coach’s beard as he watched the small guy change into his gym clothes. He could already blood rushing to his dick. The light swipe he gave it, only made the sensation double. He tried his best to keep calm but a low growl was coming out of his throat. Knowing just how much power he had nestled between his pecs, was making it all the better. With this whistle, he was really going to be a great coach. 

“Alright,” Donny said. “Ready to help make me big?” 

Coach gripped his leg tightly at the pure joy Donny had when he said it. “I am,” it took everything in his power to hold himself back. Coach dug his nails into his skin but it only seemed to turn him on even more. “Let’s get started.” He led the smaller man to the gym wondering what he was going to make the commands be. So many thoughts ran through his mind he wasn’t sure where exactly to start. 

The gym was always rather small but there were a few other guys still working out. Each one clearly had their own reasons but Coach wasn’t going to focus on that. He led Donny back to the squat racks. “Let’s start out light. Try squatting the bar.”

“Okay…” Donny agreed and set himself up to lower the bar. His body shook as he hadn’t ever done anything like that before. Feeling the forty five pounds on his shoulders, as he dropped down to the ground was tough, but he managed to make it back up. Coach watched as his body struggled. 

He blew the whistle. “Alright. Good job. But Donny, you want to be a linebacker. You’re going to have to lift a lot more than that.”

“Who told you I wanted to be a linebacker?”

Coach tooted the whistle. “You did,” he smiled as he started packing on several forty five pound weights to each side. It easily weighed much more than Donny. 

“Don’t you think that’s a bit much?” Donny asked. Feeling how unstable he was with just the bar, he was clearly getting nervous with amping it up so much. 

Coach blew his whistle. “Nonsense. You’ve been working out hard for years. Your body produces so much testosterone, it needs to work it off some way every day. It drives you to be bigger. Stronger. Faster. Growing is an erotic experience for you, so it’ll never be enough. And Donny,” Coach’s thick hand on Donny’s shoulder, “you’re already such a bear of a man that I don’t know how much more I can show you… Unless there was another reason you came to me?”

Donny took a step back. He could feel his body changing. A huge part of his reality was slowly starting to turn in on itself and he couldn’t think straight. “Coach?” he questioned feeling the testosterone start to run through his veins. The growth started in his hands. He looked down and saw them start to stretch out and thicken. His thin fingers doubled in size and then kept growing. It was hard for him to hold up the meaty hands as they were far larger than what should have fit onto his arms. 

But that growth quickly took to his arms. Thick defined forearms filled the lower part of his arm while even thicker bully biceps and triceps filled the upper parts. The bones lengthened to what his new height would be, so his knuckles drug against the ground for the moment. He looked up at Coach unsure what was happening, yet somehow oddly aroused. Just as Coach had said, the growth was ‘erotic’.

It didn’t help that the testosterone seemed to have made a stop around his dick, only encouraging him even more. The more average sized tool, quickly grew to something far more substantial. His balls dropped further and grew a bit larger. But even with the growth in his hands, the rod still was about the size of both of them together. Donny fell on his ass as his weight shifted more.

The growth went to his feet and up his legs. The spindles bulked out to twice and then three times their original size. Thick quads and calves grew onto his legs. It didn’t matter that his legs were growing longer, as they looked thick and full of strength. His height was easily soaring past six feet. Well over 6’3”. It didn’t seem to stop as his body just kept growing larger and larger.

“Oh Coach…” Donny moaned out, feeling the growth rupturing through his entire body. His clothes kept threatening to rip but then gaining the fabric necessary to keep his hulking body contained. At a few points his toes had escaped the confines of his shoes but then the shoe covered them right back up. Every bit of Donny was telling him not to pull out his dick and masturbate right then and there, but he was quickly giving up on that idea. 

“That’s it,” Coach goaded. He blew the whistle again. “The bigger you get, the better it feels. It makes you hornier. More confident. And you can have sex with more people. People are turned on by your size.”

Donny started to gain control himself as the feelings started to become normal. A fierce look formed in his eyes. “Do you want me to fuck you?” he asked.

Coach felt his body shudder. The truth of his previous statement was starting to affect him. He could feel himself getting turned on by just being in Donny’s presence. His 6’8” 300 something pound burly frame was calling out to him. He’d just watched the small unassuming nerd nearly triple his weight and grow over a foot taller. 

“Well?” Donny stood up. The height difference was even more apparent. Coach had to crane his neck back to look the other man in the eyes. He could almost feel Donny’s hard rod touching him.

The tilt of Donny’s head with a raise of his eyebrows sent Coach over. He dropped his shorts to the floor and Donny took his lead. He let his 11 inch rod out of its confines and pressed it against Coach’s asshole. Coach fell against the mirrors. His hands clenched as he felt more of Donny’s dick push into him. The hole seemed to open around it but was tight enough that he could feel pressure all the way through. 

Donny flashed a confident grin as Coach let out a moan. It only seemed to encourage him to go harder. Each thrust seemed to get another sound out of the coach. And feeling his asshole squeeze tightly around Donny’s dick only made the experience better. He let out a powerful roar and then felt his cum fill the other man up. Coach seemed to have a similar reaction as he sprayed the mirror in front of him. 

“Damn Coach,” Donny smirked. “I knew working out with you was a great idea.”

Coach returned the smile. He pulled up his underwear and khaki pants, trying not to make more of a mess than he already had. “I know. I seem to have that effect on people.” Coach left Donny to finish the workout they had started, completely unaware of the other guys in the gym who were now also sporting boners as they worked out to be bigger, stronger, faster and be filled with an ungodly amount of testosterone.
