My girlfriend requires condoms! She absolutely won't let me do it raw! We've been together for a while and I love her, but we still can't do it raw... I was starving for raw sex, and my girlfriend's older sister, a former idol, showed off her big tits and tempted me by saying she's OK with cumming inside me! I can't resist when my favorite older sister presses her breasts against me! Covered in her pussy juices and cum, the thrill and sense of guilt makes my erection go away! In the end, she found out, but , it's better to be able to cum inside!
