I have posted something like this in another thread regarding my exgf. She always wore short skirts or dresses and then we would go to a local night club that had a dimmed dance floor. She would have a couple of drinks first (Dutch courage) then she would go to the toilet up a step set of steps with always groups of guys waiting at the bottom and bring back her thong. I always knew she had taken them off because of the reactions of the guys at the foot of the stairs. She would put the thong in my pocket then head for the dance floor on her own. She would go into the crowded floor just enough for me to see her, but far enough so that other dancers couldn't see her antics. She danced VERY provocatively and would soon attract guys dancing with her. She would look at me with a very wicked smile and her hands would go behind her back. I would see her backing into one of the guys she was dancing with and the expression on the guys faces as she groped his cock and balls through his pants was priceless. Sometimes she would turn to face the guy and kiss him as he would grope her. if they were in the corner she would let him fingerfuck her as his arm would be hidden from sight. She would then come back to me and kiss me in front of the guy that had followed her and he would then walk away. Sometimes she would say in my ear "he has a nice cock, can I fuck him?". I obviously always said yes so I would either wave him to me or she would go bring him to me and I would explain that there was a quite park near to the club and we would meet him there. It always ended up in great fun with never an alternation. She would be happy, I was always happy and the guy, or guys, went home with empty sacks.
This is what she was like. Very tiny and extremely adventurous
