My girlfriend needs a condom! She won't let me do it raw! We're both students, but we're lovers! We can't do it raw... I dream of having raw sex, and when my girlfriend's sister showed me her big tits, she tempted me by saying she was OK with cumming inside me. I love her, but I can't miss the chance to experience raw pussy for the first time! I can't resist, and the thrill and sense of guilt make me more excited than when I was with my girlfriend! I kept doing it whenever I had the chance, and she finally found out... but it felt so good that I ended up cumming inside her sister!
