A fit male

You see you fit male body. You regularly hit the GYM so you're in fairly good shape but you're not a crazy about getting muscled. Your shortish brown hair matches your eyes which, as you walk by, drift to your crotch and you think of your decent nine inch package. Your most prized possession. You reach your school and head to class. First up is Chemistry. Your teacher turns up late and soon you're looking around the classroom for anything interesting. Then, beside you, you see some one fidgeting.
