Cheating partners

Date: 11/3/2017

Multiple scenes but I only remember these two at the moment. I am with Debbie and we are in the city. I think she is drunk. A guy comes up to her and says something. They go off together into the foyer of a building and I can see them through the glass walls. Debbie is lying down with her knees up and the guy has his head between her legs giving her tongue. I look around and there a a few people looking through the glass wall at them. Everyone can see it. Next scene I am in a kitchen with 2 females but one is kind of in the background. The other is a middle aged blonde. We are talking and she is leaning against the kitchen bench as if to emphasise her shapely body. I think to myself that she is flirting with me.
