Making deep muffled sounds against his mouth, Mary's hips bucked up towards his over and over again as much as she could. She didn't seem to mind her legs pushed back up against her chest, because god it felt good being that exposed and his cock sliding in and out of her like that. Her hands slid down to his ass, grabbing it with both hands and reached up to kiss him again. She'd be over the edge in no time at this rate.
