On the carpet, the blonde mistress, legs spread wide, orders her boyfriend to fuck her with the anal plug. He obliges, pushing it in and out, stretching her ass. She arches her back, whimpering, "Harder!" He slams into her, the plug rubbing against his cock through her thin, wet walls. She screams in ecstasy, her body trembling with each impact, her stocking-clad legs quivering.
