To fulfill the wish of a client who desires to have sex with a relative, Koichi Takahashi steps up... The entire incest plan is captured on hidden camera! A younger brother wants to have sex with his sister (who is divorced and currently living together). The sister becomes a nude model as a stand-in for her brother's work mistake. Confused by the director Takahashi's instruction to make her nipples erect while disguised as a painter, things get even worse when he finds her wet female genitalia and gives more lewd instructions... She feels intense pleasure and orgasms as a penis is inserted. Later, she becomes a model again wearing an eye mask and gets naked, and the male model = brother enters the room. Unaware of anything, the sister entwines with her brother... The brother, aroused by his sister's arching back and panting, fails the plan. After persuasion, she agrees to 'just once'... She strokes the penis in a reverse cowgirl position, repeatedly reaching orgasm from her brother's fierce hip movements.
