My girlfriend has small breasts, is reluctant to have sex, and requires a rubber band... Her older sister is the complete opposite! ! She has big breasts, is very naughty, and seduces me by saying that she is OK with raw sex and creampie! ! She feels guilty if she is seduced by such an older sister, but she can't help it and puts her aside and has fun with her! The thrill of being found out by her sister got me so excited that I got fully erect!
