Your hot step-mom barges into your room wearing tiny silk pajamas that hug her curves and leave nothing to the imagination. She complains about the heat, saying your room feels so much cooler. Without waiting for an answer she climbs onto your bed and suggests taking a nap together to cool off. She teases that she doesn’t mind if you sleep naked, her voice low and playful. Moments later she presses back, rubbing her huge round ass slowly against your cock through the sheets until you’re rock hard. She grinds a little harder, whispering that maybe neither of you is really in the mood for a nap anymore.
