Kazoku: Haha to Shimai no Kyousei – Episode 3 (EN)

Stepmother Otoha, overwhelmed by guilt after climaxing from Itsuki's advances, questions why he releases inside her again and again. Despite her protests, her aching, overflowing body betrays her, and Itsuki's throbbing erection forces her to accept his deep, punishing thrusts as justification—"If I refuse, the daughters..."—becomes a hollow excuse. Her mature, juicy flesh greedily swallows him whole in intense morning bathroom scenes, marking her deepening fall into insatiable lust.

On the crowded commuter train, stepsister Nagisa endures a stranger's groping hands on her plump rear, frozen in terror and humiliation. Itsuki intervenes by forcibly penetrating her, claiming her virginity in public—then boldly declares her body belongs only to him. As he ravages her breasts and rubs his exposed member against her in the swaying carriage, Nagisa feels conflicting emotions: gratitude for his "rescue" mixed with rising shame and undeniable heat deep inside. The episode escalates to school toilet violations where Itsuki mercilessly defiles her further, distorting her once-kind big-sister facade into lewd, moaning submission. PoRO's fluid animation captures every quiver, drip, and twisted expression as the stepfamily's bonds dissolve into raw,汁-daku (fluid-soaked) incestuous ecstasy.
