"While we waited Liam to come back, who else wants to get hair down there?" Mr Mendes asked to the remaining boys in the class who awkwardly looked at each other after seeing what happened to their other classmates.
When Mr Mendes saw that no one seemed to want it, he began to look for his volunteer for his own. After a quick skim, he noticed that Troy, a brown haired boy and the wrestling team star, was sleeping in the bottom maybe before the class started. He was like that and he didn't care at all about his grades or the teacher, he was deeply sleeping.
"I think we can give Troy a little surprise when he wakes up." Mr Mendes as he looked through his book. "But first, we must take his clothes off."
With a magic spell, Troy's red jersey, gray jeans and black sneakers vanished in the air leaving him wearing just his underwear, a jockstrap that didn't seem too clean.
"And now..." Mr Mendes used a spell to make him big.
Almost immediately Troy's body began to get taller. The small amount of hair
around his ankles quickly began to spread up his lengthening legs. His waist began to
grow and his stomach began to gain a little fat. As his body passed through puberty, Troy's jockstrap began to strain and tighten. A line of hair started to spread out of it and up his chest. After a few more seconds the hair had spread outward and covered his pot belly and chest. His face quickly grew a full beard as the growth stopped just before the jockstrap burst.
"Oops, wrong spell. This isn't the one I used before. He's way more older than 18." Mr Mendes said while he looked for the right spell. "Here it is."
Troy's belly began to deflate while the hair on it decreased to just a trail up to his
chest. His waist shrank back down to a size 31 and the full beard on his face thinned until a light 5 o'clock shadow remained.
Troy looked as old as the other young men in class now but to mr Mendes' surprise he was still changing. Troy's stomach slimmed down even more until his abs appeared, at the same time the rest
of the muscles on his body began to grow and tighten. His shoulders widened, his
pecs perked up and his arms bulged. The bulge in his jockstrap grew so big that it burst and a fat cock flop out along with a very big and hairy nutsack.
Almost immediately, Troy woke up and quickly noticed that everyone was staring at him.
"What are you looking?" He yelled in a definitely manly voice. "Huh?! What are these guys doing in the classroom?" He watched at his other transformed classmates. "Oh shit! They're nude! Gross! I don't need to see their hairy balls!"
"Don't you want to join them in front of everyone?" Mr Mendes asked him. "It's the least you can do after sleeping all the class."
Troy reluctantly obeyed. The remaining kids were giggling cause he didn't seem to realize what happened to his body.
"Ok, I'm here. Can I go back to my seat now?" Troy asked when he realized that he was seeing mr Mendes at the same level. He looked around and saw the kids giggling and the young men next to him as tall as him. That's when he saw himself and realized what happened. "Oh fuck!!" He yelled when he saw his hairy body and the big fat dick pointing upward between his brawny legs. He immediately turned red of shame and tried to cover his new manhood while the class burst into laughter.
