So in my final year of university, me and my gf (at the time) were quite drunk. There was only us in our shared house. Her gay best friend was coming to stay for the weekend as he was alone, he was at the pub working. We were watching a film and a sex scene came on which turned us both on, so we went to my room as we knew her bestie would be round anytime.

She was giving me a bj as he walked in my room. We just laughed it off and he went for a shower and change etc. Me and my gf carried on, I was going down on her and rimming her when he walked in again. This time he just had his underwear on, asking if he could join. Like I said we was quite drunk and just went for it. So my gf gave him a bj while I fucked her, and we swapped but he wanted to do anal. We kept swapping until he finally asked to give me a bj… which i let him. At this time my gf went for a drink, he said told me he had always fantasied being with me. At this point I pinned him down, lubed my cock and began to fuck him while wanking him too… it felt amazing.
My gf came back and just watched us for a bit. Then demanded she be the one to make me cum, pushing me on my back and riding me. He then put his cock in my mouth, and I fingered him making him cum all over me, and I finished by cumming in my gf ass…

Safe to say we did this again a few more times… and once I just met up with him.
