I was at a party dancing around with this short skirt on and some very small bikini panties underneath, as I was dancing around I could feel my too small panties creeping down some on my butt in back, every now and then I would have to excuse myself and pull them back up, I was slow dancing with a guy and once again I could feel them slipping down pretty far on my cheeks,after dancing with him I again excused myself lifting my skirt up and they were way down my ass, I wondered if anyone else saw, all evening I continued pulling them up and once thought of just taking them off but no way I could be out around all theses people naked underneath
