Things escalated with gf and a guy
Guys, I'm kinda nervous and shaking as i write this. I can't think straight after seeing this. Me and my girl work in the same place, and have been in relationship for almost 2 years now. She is very open minded and playful. We have a thing for exhibitioning, and i let her exhibit a few times before, and we both found it very hot.
Today, some of our colleagues planned for a small get away, and planned to stay there for the weekend (i don't wanna mention the place here). We often do this. Just book some place for stay, chill, play games, have some drinks, watch some movie, sleep and return home after a day or two. It was planned the same this weekend, and we got to this place. Since it was raining, we sticked to staying indoors, but we met another group nearby who were also like us. We all got together at our place, had some drinks, chatted and started playing games just a while ago as it rained.
One of the guy from the other group kept flirting with my gf, and i noticed her laughing out well with him. When she got away for a few minutes, i asked her about it, and she just laughed it off. I felt like she was a bit tipsy as she had some drinks. She told me it's nothing serious. She even teased me a little saying how i would find it if he kissed her. I wasn't worried much at that time.
But, not just an hour ago, i saw them sneaking out while everyone was laughing and playing around the place. When i went out to check on them, they were literally doing it behind the building on the wet sand. I couldn't see everything. But got his movements between her legs. I'm still shaking with nervousness. I won't say I'm a cuck, but I admit i was hard seeing them do it. I don't know what to do now. They did it for a while, fixed their clothes, walked the other way and went out. I don't know where they went. I'm confused about what to do now, and not even sure whether i should call her now.
Anyone faced something like this?? What did you do? Or if anyone got any advice, that would be nice.
