SDMF-049 My Sister Forgets Tomorrow That I Am Having Restraining Sex With Her Every Night With A Degrading Passion. Yura Tsumeki
Tiêu đề ban đầu: SDMF-049 妹は僕が毎晩劣情のままに拘束セックスしていることを明日になったら忘れている。 紬希ゆら
I have a secret that I can't tell anyone. That I keep having sex with my sister, whose memory resets when she sleeps due to the shock of an event. At first I wanted to help her somehow through shock therapy.... But the more I continue, the more satisfied I become.... Yura has become a convenient sister for me.... I'm sorry I'm such a bad brother... I don't understand either...
