He slowly and quietly dismounted and locked his bike up against a tree a bit down the path and slowly neared the thicket. Mark was at the edge of the...cluster when he could quite clearly and plainly hear the sounds of grunting and moaning of a male and female. He repositioned himself and was at such an angle so he could see the guys back thrusting into the girl’s ass. The slut was taking anal in a public park in broad daylight!
