Boyish club girl and middle-aged coach share room at summer training camp... A female student with a strong desire to sneak in at night and has sex with 10 ejaculations

I can't believe the club advisor teacher and his students are enthusiastic about education... Rena, who belongs to the volleyball club, participates in the summer training camp. When she hears that she will be haunted at the inn where she is currently camping, she becomes scared and is unable to sleep, so she goes to the coach's room. The girl is alone with an older man and her sexual desire increases and she seduces her by saying, "Teacher, let's have sex. I'll keep it a secret from your wife." When the coach sees the growing shiny naked body, his reasoning blows away and his sexual desire explodes. They devour each other so obsessed that they forget about time.
