Tim's GF, a dominatrix at heart, prepares him for a session he won't forget. She oils his ass, making it glisten, then attaches a thick strap-on. She starts slow, rubbing his butt, then picks up the pace, spanking him until his ass is red. Tim begs for more, and she obliges, sliding the dildo into his tight ass, fucking him senseless until they both collapse, spent and satisfied.
