When a girl rubs her ass all over a guys penis. For the girl, even if she's doing all the work it still makes her wet and makes her want it to go on forever. For the guy, he just stands and enjoys. It's a win, win situation besides the fact that it never last long enough.
Tiffany grinded her ass all over Aidan's penis till he got a boner, Tiffany and Aidan both enjoyed grinding each other.

Dirty Dancing. When a girl moves her ass on a guys dick to turn him on. Or when the girl and guy face eachother and the girl rubs her pussy with the guys dick or humps his leg. It's any sexy or suggestive dancing.

when a girl is in front of a guy, and they're dancing; her butt to his crotch. he places his hands on her hipbones and pulls her closer. the girl shakes her stuff and the guy enjoys it.

The act of dancing where you rub your penis on a girl's ass in a dancing fashion It feels really good and it never seems to last long enough. Sometimes it can get really graphic and god does it feel good.
