when a girl rubs her big horny ass on a guys weiner region!!
i was at the club one night when i saw this chick dancing with her friends. her breasts were giant and you could see them through her bra less shirt!!! she was wearing tiny spandex with her big ass hanging out. i could feel a boner coming on..so i decided to please my cock and start grinding against her fine ass. I came over to her and without even asking i just shoved my slef up against her ass pleasing her every pleasure. She then put her hands on her knees and shoved that ass on me!!! i reached under and stuck my hand on her wet pussy. then i squeezed it making her moan and want more. she turned around facing me and put her leg between mine. i thrusted againstt her tight little shorts and unzipped them to have some more fun! then i slid them down and through them in the crowd!!! now it was just her red thong all to myself!! i grabbed her by her ass and pushed her onto me. i grinded that little pussy so hard i could feel the wetness of it onto my pants!. i squeezed her tits and then french kissed that chick so good! i could tell she needed to cool down so i sat her on the couch and massaged her tits to relax her some more. but i needed more for her so i grabbbed her by her thong and forced her to give me a lap dance! boy that ass was so big and firm it hardened my dick so fast! we than went outside of the club and banged each other on the bench waiting for the bus!!!!

and the rest....is a little too wet for urban dictionary

to rotate the hips in an erotic manner, in such a way that the girl's ass is grinding against the guy's crotch through erection, and sometimes even orgasm.
At the nightclub I was grinding with all the mega-hotties, so much and so intense that by the end of the night, my Dick was sore.

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.
