Okay so im a 17 years old guy, he's 25. He used to have a boner 24/24 because of the hot girls he used to teach (and touch lol). One time we were alone in the gym because he was giving me gymnastic courses in the break before my exam. He started touching my ass while teaching me how to do the backflip. He was hard and i was too so we ended up making out and blowjobing in the toilet. I feel bad lol but i had fun.
