In order to fulfill the wishes of the client who wishes to have sex with his close relatives, Koichi Takahashi stands up... Peeping the whole incest plan! A request from a younger brother who wants to have sex with his older sister who took care of him instead of his parents (became divorced and currently lives together). An older sister who becomes a nude model as a stand-in for her younger brother's job mistake. She is perplexed by the instruction to raise the nipple from Director Takahashi dressed as a painter. In addition, when she finds a wet female genitalia, the number of obscene instructions increases. At a later date, when I wore an eye mask for model work again and got naked, the male model (my brother) entered the room. My older sister who doesn't know anything is intertwined with her younger brother. After persuasion, if it's just once..., he repeatedly cums at his younger brother's violent hips while stroking his penis at the woman on top posture.
