Mary filled up

You watch Mary's bouncer partner fuck her harder and harder, slamming his dick into her wet pussy again and again. You're more than a little turned on, seeing your floormate get fucked hard bent over a desk by a random stranger. You watch as the bouncer manhandles her, groping her ass and her breasts and spanking her. She coos and moans and groans and even yells, even through the panties stuffed into her mouth. Finally after nearly twenty minutes that you've been watching this, the bouncer grabs Mary's chin and turns her face so that he's speaking directly into her ear.

"I'm gonna cum in your pussy, slut," he grunts.

"Do it," she gasps, spitting her panties out of her mouth. "I'm on the pill, it's okay, do it."

The bouncer takes hold of her ass and doubles-down on his thrusting. Mary's head falls, her neck unable to support it as her whole body shakes.

It's obvious the moment the bouncer starts to cum. You're focusing on Mary, but the violent spasm that rocks through his body is easy to see. Mary throws herself down flat on the table, mouth open in a smile, as the bouncer fills her pussy with his cum.
