SSIS-348 "So Vulnerable When In Love". Lusted After Girlfriend's Sister And Fucked Her Secretly. I'm Just The Pits. Nanami Ogura

Which would you choose, "the strong pushy small-breasted girlfriend" or "the weak-to-push girlfriend's busty sister"? I started thinking that way when I first started dating her. She is a proud girlfriend, but she is guarded against sex (crying). On the other hand, her younger sister gave me the impression that she was quiet and timid. I don't strongly resist (laughs). From there, I decided to secretly send sex activities with my sister Nanami, who is super sensitive and can have sex!
