A dedicated club advisor teacher and his student never imagined this would happen... 'Rena,' a member of the volleyball club, participates in a summer training camp. After hearing that there are ghosts at the inn where they're staying, she becomes too scared to sleep and goes to her coach's room. The girl, alone with an older man, feels her desires rising, 'Let's have sex, Coach. I'll keep it a secret from your wife.' She tempts him. Seeing the naked, alluring body of a young woman in her prime, the coach loses his reason and his lust explodes. They lose track of time as they indulge in each other.
