My new girlfriend is cute and we get along well, so she's too good for me, but she has one flaw... She won't put up with my sadistic sexual encounters. It's a shame, but there's nothing I can do about it. Just as I was thinking that, her younger sister, Shizuku, showed up. Shizuku told me that she can do things her older sister can't...!? A reverse NTR encounter with her younger sister, featuring perverted sex such as choking, spanking, and creampies!
