Anna actually has no idea who she's dancing with. There's a warm body pressed at her back, hands on her hips and grinding hard, and honestly, that's all Anna really cares about at this stage.
It doesn't take long her to turn around, chest-to-chest with her partner. It takes even less time for them to be mouth-to-mouth, either. And then they're not on the dance floor anymore, instead Anna's against a wall, a hot body pressed against hers, soft breasts and smooth skin, and it all just feels so...
Nice.
