Aila, her milky skin glistening with sweat, climbs onto her stepson's lap, facing away. His thick, engorged cock slides into her eagerly, filling her completely. She grinds against him, her big ass bouncing as she rides him in reverse cowgirl. He grips her hips, thrusting upward, their bodies slapping together in a rhythm that builds with each stroke. She leans back, her hair cascading down as she takes him deeper, her tight pussy milking his cock. Their moans fill the room as they switch positions, Aila now facing him, her legs wrapped around his waist in a doggy-style embrace, ready for the final, explosive ride.
