"How come he has so much hair on his chest?!" A girl said.
"Yeah and why is it so broad?!" Another girl seconded.
"Good questions, girls." Mr Bretman said. "I'm sure you know that boys have flat and thin chests. Our friend, Jason wasn't different from that, but, as girls begin to develop breasts and an hourglass body, boys grow in their shoulders getting a V-shape in the best case scenario. Jason's shoulders had grown since then and now he can barely cross the doorframe. That wide chest has giving him the opportunity to get big and square pectorals."
"What about the chest hair?" A girl interrupted. "It looks like a thick coat."
Jason saw down at his chest. In fact, his shoulders were really wide and he was sporting two hard rock pecs covered in a thick brown fur. He remembered he was completely skinny this morning with no sign of body hair. Those little hairs that grew from his chest looked so wild and beastly, nothing compared to the head ones that he knew. Looking how they were hanging from his bare skin made him blush.
"Well, it comes from the same place where his facial hair came from." Mr Bretman said as he put a hand over Jason's chest. "On boys, chest hair is a sign of maturity, some get a few when they begin to develop, some others don't and another ones get more even after several years. Isn't it right, Jason?"
Jason just nodded. His mind was wondering of how weird Mr. Bretman's hand feels in contact with his hairy chest. His hand barely covered a half of Jason's left pec.
"It begins to grow around boys nipples." Mr. Bretman pointed to Jason's left nipple. "Here is totally covered in fur. Then, a diamond shape grows right in the center and begins to cover all the chest. If it grews so dense, it can merge with his facial hair and his traesure trail. That's Jason's case."
Jason thought about his huge amount of body hair. He has hairy legs, hairy arms, hairy face and now they were talking about his hairy chest. He rubbed his belly and he notted he has too much hair on there too. He was hairless this morning. How this hair could spread from his skin so fast since then? How didn't he noted it? His body was changing out of his control and that makes him feel vulnerable and unknown of his own self. He feels like another person that had grown from him, using his flesh to mold a jock or something like that.
"Jason is one of the hairiest guys I ever met." Mr. Bretman said and Jason felt as if all his body hair tingled after that.
