Let her control the fight.

"Oh Cindy." you say, struggling to stay on your wobbly knees as she begins jerking your now hard cock.

"Yeah baby, just relax. I own your cock." She then pulls you back and sits on your chest in a reverse schoolgirl position.

"This is a very bad position for you." she warns.

She's right. You are trapped under her big soft ass and she has full access to your cock. You feel her begin to slide your shorts down. She bounces and grinds a bit on your chest, moving her ass closer to your neck. You can't help but be lost in it. You have always been obsessed with Cindy's ass.

You feel a tightening in your balls and realize that you might be done.
