Oku-sama no Kaifuku Jutsu

Shion — a young man unable to manifest his magical powers even after coming of age — is left in the care of a family that specializes in magical research. After finally unleashing his potential during a terrible incident, he is taken under the wing of a skilled healer — Rui — who promises to teach him how to control his powers. But to properly command magic, a man needs a profound knowledge about carnal matters.Will Shion be able to save Rui from a terrible fate, or will he let her become the village’s plaything?“I want to be pampered by a sexy, mature woman!”“I want to see a multitude of men defile a sexy, mature woman!”This game was developed to fulfill these desires.[From Jast USA]
