To fulfill the wish of a client who desires to have sex with a relative, Takahashi Koichi steps up... The entire incest plan is secretly filmed! A consultation request from the brother of the mother (Documentary Incest [53]) who accepted her son's advances a year ago due to Director Kariki's scheme. Suspecting his sister's good relationship and incestuous acts, he discovers a DVD that serves as decisive evidence. Wanting to know the details, the brother pleads with Director Takahashi. Disguising his identity, he approaches the mother and films her in a scenario where she is 'stolen' by another man as part of the couple's hobby. "I'm going to come!" she screams repeatedly as she reaches orgasm. A week later, a secret rendezvous kept from her husband. Unknowingly, her partner for her first threesome is her brother, and she rides him while blindfolded, writhing in pleasure. Even after finding out the truth, she continues, moaning in ecstasy.
