As they sat back and relaxed, Susan began looking around. She could see some of the other cabanas were occupied, and when her eyes focused on one she...could see a woman straddling a man and kissing him. Susan was about to point out the PDA to Joni and Walter, but when she looked closer she saw that the woman wasn’t just kissing her man… she was fucking him, and as her ass bounced up and down, Susan could actually see his cock disappearing and reappearing from deep in her pussy as she rode.
