Back in college (I was 19-20 at the time) me and my gf then (f19-20 at the time) went to a tailgate with my roommate (m19-20 at the time). We all got a pretty good buzz going and decided to leave the game early. Went back to my apartment and kept the party going. Drinking and smoking too. For context me and my gf then had been dating through high school and wanted to open up sexually. We hinted to each other about a three some with my roommate. So after a few drinks at our apartment and smoking a joint we sat back and watched the games. My girlfriend got up to go change and came back wearing a sports bra and some short shorts. My roommate was taking some hard looks I could tell. We eventually started playing some drinking games while watching football and it eventually lead to my girlfriend stripping for us. Later that afternoon she’s completely naked in front of us both. When she started sucking our cocks I got a bit too excited and came super early. My roommate felt bad and asked if that was it but my gf insisted they keep going. So I let them and took a seat back and watched my gf put on an amazing show. She worked his cock so good and it was so hot hearing her moan on his cock. That weekend turned pretty regular and it was so fucking hot each time
