SSIS-348 "Super innocent and easy to push over" I lusted after her sister, and kept secretly fucking her. What a piece of shit I am. Kuraoka Nami

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!
