My stepfather's slut teasing my wife, please forgive me now...

Genta is a slutty stepfather with a strong sex drive and always tries to induce sexually harassment-like skinship with her son's wife, Ryoko. As I'm spending my time insulting in the obscene fantasies of wanting to have sex with my girlfriend one day... One day, when Ryoko was injured and unable to move, he insisted that he should treat her, and Genta forcefully gropes her body, and pushes her down in one go, aiming for the opening.
