Don't Call Me Pochi by Kaoru Misaki

A boy has just graduated from high school and seeks his first experience with a man.

Hiroki Kamishiro is a boy with a noble heart. He is a boy who knows nothing scary, and he has been on molested trains and raped outdoors. He gave everything he had to us, including intense sex and masturbation. So the kind staff played with Hiroki as a reward.
