A passionate teacher and his student... Rena, a member of the volleyball club, is taking part in a summer training camp. She hears that the inn where the camp is being held is haunted, and is so scared that she can't sleep, so she stays in the coach's room. The girl's sexual desires grow when she is left alone with an older man, and he seduces her, saying, "Teacher, let's have sex. I won't tell your wife." The coach loses all sense of reason when he sees the young girl's shiny naked body and explodes with sexual desire. They become so engrossed in devouring each other that they lose track of time.
