S to M Dai ni Shou

Saya had planned a scheme so that Sakiko, who works under Makoto, would witness her sexual affair with Makoto in the office. Makoto's home is about to become a broken one when his wife Sachiko is told of her husband's unfaithful doings. Saya, simmering with bottomless vengeance, exploits Hayakawa, Makoto's daughter's private tutor, to lure Sachiko into committing adultery - and in the end, nothing can hold down sexual desires.
