How To Grind An Ass: Clit Stimulation

Clit stimulation via ass cheeks is the most erotic act to perform. If you consider it, I recommend that you do it with a female. A man's ass is not as plump. This act works wonders if her ass is PHAT! The Bigger the ass the better.

First you position her by either having her stand up, and you stand behind her
or you can have her lay flat on her stomach.

Take some baby oil (just a little) and put it between her ass crack.
The baby oil moistens up her crack, and it looks erotic because
the crack of her ass look wet.

If you are standing, have her arch her back with both arms outstretched
touching the wall. Grab her hips, position your pussy directly in front of her
ass. Then grind into her ass while holding her hips. Grind as hard as you can, 
back and fourth, round and round. You'll start to feel your clit warm up against
her fat ass cheeks.

If she is laying down, lay her flat on her stomach. Climb on top of her ass, spread your pussy lips, and sit down. Grind using all kinds of rhythms  back and fourth, circular, the stiff motion. I'll guarantee you that her big, fat, fluffy ass will have you squirting.

You can also grind her ass having her sit between your legs in an open position. This is double the pleasure because you get a mixture of ass and pussy.
