Tsugumi, the sister who is treated like a meat slave by her incestuous brother with insatiable lust. He finds her all over the house and forces her to perform fellatio on his erect penis, licking and groping her soft body repeatedly while enjoying her reluctant expressions. Finally, he rubs his rock-hard penis against her smooth crotch and inserts it directly. Although she resists with all her might, her womb gradually grows hot, and unconsciously she hugs him and starts moving her hips on her own. After a relentless, prolonged piston action, he ejaculates his semen deep into her womb.
