SSIS-348 “I’m vulnerable to being messed up with Ubu.” Nanami Ogura

Which do you choose, “She with small breasts that is strong against pushing” or “Sister with big breasts that is weak against pushing”? I started thinking that way shortly after I started dating her. She is proud of her, but she is a guard against sex (crying). On the other hand, her younger sister seems to be quiet and weak, and I, who was the limit of Muramura, touched my sister’s big boobs … eh! You don’t resist strongly (laughs). From there, I decided to send Saddle sexual activity secretly with my sister Nanami who can SEX and is super sensitive!
