Long story short, had a potential 3 way lined up with a buddy and his girl. We live in different locations but met up in Barcelona last summer.

We had some drinks and things warmed up, got very flirty on the beach and discussed how we could do it, likes & dislikes, boundaries etc. we decided to see more of the beach and did some walking and came upon the nude area. The girl was naked before my drunk brain could even register what was happening. My buddy looked at me, shrugged, and got naked as well. He was packing an average cock, maybe 4in soft and cut. Respectable.

I took a second and figured "fuck it." Now keep in mind, quite a bit of booze and swimming mean no one is at their biggest. I pulled off the shorts while the girl stared eagerly in anticipation. By the time they hit my ankles she had turned away to muffle a laugh. I was practically just foreskin at this point.

My buddy slaps my shoulder and said, "sucks for you bro!"

We hung out on the nude beach for a while and I caught her looking a few times, by the end she didn't even try to hide her gaze.

Needless to say, I had to jerk it while they fucked in the next room
