This role-play is performed by adults. I was living with my girlfriend. One day, her older sister Marin comes to stay with me for a week... Then, there are days when I can't help but worry about my older sister's panty shots and breasts being exposed without her realizing it. I finally got so excited and lustful that I couldn't control it anymore...I ended up having wild sex without telling her. "Oh, I can feel my boyfriend's eyes on me..." My crotch is fully erected by the erotic body line and flickering rhythm of Takamine Hana's older sister!
