In 'Seikatsu Shuukan The Animation', a young man moves in with his new, beautiful stepsisters, Rina and Airi. Underneath their seemingly perfect exteriors, he discovers they harbor 'bad living habits.' Taking on the role of a strict disciplinarian, he embarks on a mission to 'correct' their behavior through intense and repeated sexual re-education. The series follows his carnal crusade as he systematically breaks down each stepsister's defiance with his cock. He fucks the messy Rina into becoming tidy and drills the promiscuous Airi into submission, using every hole they have to enforce his lessons. Each episode is a raw depiction of incestuous domination, where the brother's forceful sexual acts, from deep anal to rough vaginal pounding, are framed as necessary 'therapy' until both girls are completely broken to his will, their bodies used for his pleasure under the guise of household correction.
