STARS-590 I’m a positive girl, but I have no sexual know

Super new project! Yin Ka-san, a naive gal who is asked to practice SEX by a childhood friend Yang gal! I’m interested in sex, but … knowledge is zero and experience is almost zero … almost like that A virgin gal struggles to learn SEX in the Reiwa era !! If I think that I can do whatever I want with a reversal of position … What will happen !?. STARS-590 I’m a positive girl, but I have no sexual knowledge and I’m going to practice sex with my playhood friend (almost a virgin) who is erotic and naive. Hikari Aozora
