The father, "Ippei," drinks and gambles from morning till night to divide the insurance money left by his mother after her death. His son, "Haruto," studies diligently every day to escape poverty, aiming to get into a national university. One day, to help the poor Haruto, his teacher suggests they hire a tutor. The beautiful and gentle tutor, "Mei," increasingly attracts Haruto. However, seeing the two having fun, "Ippei" begins to speculate about when Haruto is away from home and summons "Mei." Oh! Dad, how could you do this! He uses a powerful aphrodisiac to awaken her, making her unable to control her pleasure. In the sweltering, filthy room, at noon, he begins to have sex with the father who is teaching his child! The father's violent thrusting causes her to scream continuously, gushing forth like a tidal wave! The beautiful female tutor, overwhelmed by aphrodisiacs and pleasure every day, is increasingly breaking down! The sadistic father, beside his son who has taken sleeping pills, forcibly engages in physical combat with her! Dad, you're so amazing! I'm going to ejaculate again!
