Dexter lay on his bed, his heart racing as he heard his mom's footsteps approaching. Her cleavage was on full display in her tight top, and he could still smell her perfume from their morning encounter. She climbed onto the bed, straddling him in reverse cowgirl. Her skirt hitched up, revealing her lace panties. Teasingly, she lowered herself onto his hardening cock, letting out a moan of pleasure. She began to ride him slowly, her hips grinding against him. Dexter's eyes were glued to her round ass cheeks as they flexed with each thrust. This was the hottest thing he'd ever experienced.
