This title is actually the fifth installment of this series, which is basically hentai about MILFs. Misako is pissed that she catches her stepson Kazuhiko with his dick up her sister's Emiko's butt, because she wants Kazuhiko for herself. She molests Kazuhiko in his sleep, but of course he was only pretending to sleep, and he wakes up and turns the tables on her. They spend a whole day together in which they spend a lot of time fucking in a public bathroom where she sucks and jerks off anyone he tells her to and does anything he wants.

Emiko's husband wants her to move away with him. When she goes over to tell Kazuhiko, she finds him fucking Emiko again and that ends this part of the series. Pretty hot and a nice change from schoolgirls, the usual material for hentai tapes.
