IENFR-45101 - I enrolled in a beauty school, but I'm the only guy surrounded by gyaru girls!

I enrolled in an esthetician school, and I'm the only guy! During practice, the girls' towels keep slipping, revealing their breasts and butts everywhere! When it's my turn to be treated, they touch me in such sensitive spots that I can't help but get fully erect. Then the instructor says, 'Usually you'd hold it in, but in this case, I think you should just let it all out,' and things get wild.
