His ex-girlfriend

John was stunned to see his ex-girlfriend standing there. She had an equally stunned look on her face. She was also blushing given the fact that the towel was the only thing preventing her from being naked.

"I guess you know each other," Alicia said dryly.

"We used to date," Crystal said.

"I don't know why you two broke up, but you're missing something special, Crystal," Alicia said. She wrapped her legs around John. "You're missing his cock."

"Not really, seeing that she was fucking my best friend behind my back," John replied. "I caught them at it. Now, it seems that turn about equals fair play." He smirked at Crystal and went back to thrusting into Alicia's pussy.

John and Alicia kissed as they continued their tryst. He began thrusting wildly into her, causing her to moan loudly. Out of the corner of his eye, John saw Crystal watching with a mixed reaction. Half of it was anger, but half was lust.
