My night didn't involve any sex. It did feature a lapdance which I didn't really want... it was kinda surreal that she says good luck with my wedding just after she's finished dancing naked on me.
At another friends night (after I was married) I asked her to dance for my friends but she kept pointing her pussy my way and asking why I wasn't watching.
I was very naive that night, assuming that they would show some respect when they solicited a dance and I said simply: "I'm married." I was wrong.
