The next day after getting home and sneaking his way into his bedroom to avoid his parents finding him naked. Justin was in a good mood.
He had arrived at schools and at first nothing had really changed, however whenever he passed by girls he saw them take in his muscles and giggled and blushed when Justin made eye contact with them.
During PE he ran faster than anyone of the kids while they played dodge ball, Justin was never hit once in the entire game. The coach himself even gave Justin an applause and asked Justin if he could speak with him after class to discuss something things.
Despite this newfound fame at school, Justin made sure not to let it go to his head, he after all was still the same guy even before he found the mask.
After PE, Justin came to meet with his gym teacher as promised after class and sat down in his office, the shutters closed and door locked.
When the coach saw him come in he made a massive smile. The coach's name was Mr. Green, a twenty six year old who had recently got hired at Justin's school.
"Well well, Justin you've changed a lot since I last saw you, your almost a new man!" he exclaimed.
"I haven't changed sir, I'm still the same old me." Justin said modestly.
"Well If you want to be modest go ahead young man." Mr. Green smiled. "Your pretty much a star student at this point. Good grades, you never get in trouble with anyone and you've suddenly become incredibly skilled in sports! Now I know some people will assume you've taken steroids but I've seen people under the affects of drugs like that and your not one of them."
"Thanks Mr. Green, I'm not quite sure how it happened either." Justin said.
"Well, what I do know is that I want you to join the soccer team, you'll be a valuable asset if you join us."
Justin was slightly surprised. He didn't know much about sports but he did know his school was halfway through the season. Was it really alright for him to join?
Mr. Green saw the look on Justin's face and laughed. "Don't worry, we can all adjust, if you want some time to think about my offer go right ahead. Take a month or two if you really need it."
"Alright then."
Suddenly an idea ticked into mind. The kind of sexy idea. Justin smiled inside. This would work.
"Oh that reminds me, Mr. Green there was something I wanted to ask you." Justin said.
"Sure go right ahead. What do you need?"
"Well the shower in the boys locker room doesn't work I was hoping if you could take a look at it."
A look of confusion crossed the teacher's face and then cleared.
"Oh really? Well, I'm surprised no one else reported this, I'll go take a look at it, I was going to take a shower myself soon, how about you go to the locker room and wait while I got get my tools." He said
"Alright Mr. Green."
Justin left the office and hurried to the locker room. He arrived there quickly and luckily no one was there. Justin then found one of the shower heads and bent it upwards, enough so that it would look broken. Justin even in his human form did this easily as he bent the metal.
Justin then waited for Mr. Green to arrive, and showed him the bent shower head.
"Well, I can see how that could be a problem." he said as he examined the bent shower head.
"I won't be able to fix it myself so I'll have to find a janitor or something to take a look at it. I wonder what happened to it, might've been one of my kids in PE class." Mr. Green said to Justin.
Behind him, he heard Justin turn on one of the shower heads already showering naked.
Me. Green was slightly unnerved by this but ignored it, after all he did watch other high schoolers shower before to make sure they didn't get up to anything.
"Oh alright Mr. Green, I'll just use this shower instead, Justin turned around his hairy penis in sight.
Mr. Green couldn't help but stare at its hugeness, it was massive even in it's flaccid state. He wasn't gay but that didn't mean he didn't have his curiosities.
Justin started to slowly stroke his dick moaning at the touch and watched as it grew bigger and bigger.
Mr. Green noticed his own boner form in his pants and any resistance to his natural urges disappeared as he saw Justin's canine dick leak slightly.
Justin stopped masturbating for a moment to walk up to his teacher and began to strip him off, he smelled his dick instantly and gave it a nice lick that made Mr. Green moan harder.
Before long Justin shoved his massive dick into Me. Green grunting and panting as his penis filled his gym teacher. Mr Green could only moan as he was penetrated fiercely, one of his hands stroking his own dick In the process.
Finally Justin gave one last thrust into Mr. Green releasing his spunk into his ass. Mr. Green didn't move as he layed naked on the shower floor, knocked unconscious after the pleasurable experience he just had.
