When I went to my girlfriend's house, I was seduced by a sexy, beautiful, big-breasted woman who was the complete opposite of my childish girlfriend! I care about my girlfriend, but I can't resist being seduced by a woman like this! And unlike my girlfriend who only lets me have sex with her using a condom, she's okay with having sex without a condom! And she's okay with cumming inside me! Even though my girlfriend is right next to me, the raw sensation feels so good that I can't stop thrusting! I don't want to be found out, but I'm so excited about this relationship that I can't stop!
