The series plunges headfirst into the twisted desires consuming the Hasumi household. The narrative centers on Shino Hasumi, a seemingly prim housewife who finds her world upended by the arrival of her husband's manipulative and virile subordinate, Mita. Across the series, what begins as Mita's calculated seduction spirals into a torrent of raw, unbridled lust. Shino is systematically broken down and remade into a vessel for Mita's carnal whims. Viewers witness her initial resistance crumble into desperate, moaning submission as Mita relentlessly plows her cunt in every conceivable location, from her own marital bed to the cold tiles of the bathroom floor. His thick, throbbing cock becomes the center of her universe, filling her mouth until she gags and stretching her pussy to its absolute limits. The corruption spreads to her innocent stepdaughter, Kanae, who is also ensnared by Mita's predatory charm. He initiates her into a world of depraved pleasure, teaching her the ecstasy of being fucked raw. The episodes graphically detail their illicit encounters, showcasing Kanae's transformation from a shy girl into a wanton slut who craves Mita's seed. The climax sees both mother and daughter fully debased, eagerly sharing Mita's potent cock, their moans mingling in a symphony of incestuous, adulterous depravity. They become his willing fuck-toys, their bodies used and filled repeatedly in scenes of intense gangbangs and creampies, leaving them soaked in semen and utterly dependent on their shared tormentor.
