My girlfriend won't let me do it raw! We're dating, so I'm happy to let her do it raw... But then her sister seduces me, saying she's OK with doing it raw and cumming inside her! I love her, but there's no way I can refuse when such a beautiful and lewd woman seduces me! The thrill of being found by her and the pleasure of cumming inside her, which I don't usually get to do, get me excited to the max... and at the end, I cum inside her a lot right in front of her!
