After learning that his son wished to engage in sexual relations with a close relative, Takeki Takashi sets out to fulfill this desire. The mother, a domineering "education mom" who had become increasingly obsessed with incestuous acts after watching adult videos, agrees to an interview at a café under the guise of being questioned by a freelance writer—actually a crew member in disguise. As the interview progresses, she is gradually seduced, moved to a drinking establishment, and slowly gives in to physical advances. Moaning "Don't call me mother...", she writhes in ecstasy as her genitals are licked. With her lustful nature fully exposed, she is blindfolded and, unaware that her partner is her own son, attempts to mount him in the cowgirl position. After the son ejaculates, the mother, now realizing the truth, proceeds to lick his penis, screaming "I'll be your sex slave!" as she loses herself completely in depravity.
