ADN-338 I had indecent sex with my sister's husband, who is a piece of shit, many times. Maihara Sei

My younger sister Reiko, who ran off, comes with her husband. She is nervous about Reiko's husband, who she meets for the first time, but her eyes are waiting for the two of them. "Onee-chan!" Reiko bursts into tears as soon as she sees her eyes. Reiko claims that she has been unfaithful and that she has been caught cheating on her. A change from her celebratory mood. To the Hitomi couple who welcome the two with an awkward atmosphere.
