Bowling ball

You reach for a ball from the rack. You place it on the floor. You straddle it, knees splayed out, hands on the floor. You have the holes pointing up creating an uneven surface that should feel better than just the smooth ball. You start moving your hips and sliding your slick clitoris across the surface. You keep sliding it back and forth. Back and forth. Both the vision of you masturbating in front of this crowd and the sound of your wetness makes a couple of the men start running the front of their pants. And that makes you move your hips faster and faster and faster. You use one of your hands to start playing with a nipple. You keep grinding and grinding against the ball until you orgasm in front of this crowd and you collapse forward from pleasure, leaving your ass and pulsating pussy up in the air for all to see.

It takes a few minutes to regain yourself and you remember you have one more bowl left.
