A first-hand document in which Ruri Arisawa gently and carefully guides a virgin boy to his first experience. - What should I do to overcome premature ejaculation? Ruri-chan tells the virgin boy, who is nervous because he has sex for the first time because he doesn't know what's right and what's left, that it's okay, and starts massaging her breasts, how to torment his nipples, and how to fuck him. She puts her body on the line and teaches her how to torture her pussy. - She tried inserting it, but she still ejaculated prematurely and ended up ejaculating... - In the second round, I spent more time concentrating on foreplay, honing my skills to make the woman feel good, and then inserting myself. - Was it possible to prevent the second ejaculation from erupting?
