so, we had been to that swinger club before on weekends, where there are mostly couple. And we were just interchanging couple and so on...typical stuff where you simply fuck the other couple partner. But during the week there were almost only men, looking for the few girls around.
I always had a fantasy of seeing my GF sucking some other cock (I like watching gloryhole porn movies). so I told her that I wanted to see her sucking as many cocks as possible that night (I was very high). There is a room with some sort of gloryhole (some wooden wall with holes). I put her on one side and called men to come. She was not completely sure but she was ok at the end.
So I just let myself go and went all the way. She tought I did not want her to take sperm in the mouth, but I told her instead that I wanted to see her to swallow the cum of the men (that turns me on). I told her not to swallow inmediately but to show me cum in her mouth and later swallow.
It actually worked quite well, some men wanted to fuck her but I expressely only allowed sucking and told the guys to come in her mouth (some guy when they where about to cum where saying "I am coming" and remove the cock to cum outside, out of respect), but I told each one that I wanted them to cum in the cum so that my girl could swallow all the cum. For some of them I also recorded a short video with my phone (with their permission , only showing their cock and my GF face), so we can watch it later.
It was funny, with a couple black guys she said that could barely swallow as it was too much, she showed me and her mouth was in fact completely full with cum.
I am not sure how many guys came, some 15 I think, some could not come, some came inmediately like after 2 seconds (they apologized but I actually found it quite hot, expecially because the premature cummed A LOT, lol).
There were more men but my GF was tired, and a little bad of the stomach, she said it was too much cum to swallow (I think she was just tired, some guys took a lot of sucking to come).
It was a nice experience.
