Kazoku: Haha to Shimai no Kyousei – Episode 4 (EN)

Stepsister Kaede confronts stepbrother Itsuki with fiery resolve: "I won't let you touch Mom or big sis anymore!" She still idolizes him as a brother in the past but now sees him as a despicable predator—unaware that both women have already been thoroughly claimed and impregnated by him. Itsuki lets her declaration stand unchallenged, then lures the competitive-swimsuit-clad Kaede into the school changing room, where he greedily devours her toned, athletic body in a forceful, lustful assault that crushes her resistance.

Itsuki visits Otoha's workplace to secretly admire her commanding figure as she issues precise instructions to male subordinates with dignified poise. Beneath the desk, however, she is compelled to perform a footjob with her stocking-clad soles expertly stroking his rigid length, all while maintaining her professional demeanor—leaving Itsuki both aroused and impressed.

Otoha then learns a shattering secret about her husband that destroys the final foundation of her fidelity, the last restraint keeping her from fully surrendering to Itsuki's member. An uncontrollable ache surges from deep within her body, impossible to suppress any longer. Meanwhile, stepsister Nagisa senses rising terror intertwined with undeniable fiery heat building in her core, foreshadowing her own inevitable corruption. The episode features explicit foot fetish scenes, office humiliation, school swimsuit rape, and the accelerating collapse of family bonds into raw incestuous desire.
