A slut, legs spread wide on the sling, awaits her mistress's touch. The dominatrix, a vision in latex, begins with a sensual pussy tease, then slowly inserts her fist, knuckle by knuckle, into the slut's dripping snatch. The slut gasps, her pussy filled to capacity, as the mistress begins a relentless, fist-deep fucking, bringing the slut to the brink of orgasm again and again.
