As she struts around in revealing outfits, she teases him mercilessly, until one day, she decides to take it a step further. Sneaking into his room while he's showering, she slips into his bed, her big tits pressing against his back. He awakens to her grinding her big ass against his morning wood, and despite his initial shock, he can't resist the temptation.
