The cuckold's eyes widen as his Mistress reveals her surprise, a massive strap-on cock glistening with lube. She orders him onto his knees, presenting his ass to her. She teases him, slapping his cheeks, running the head of the cock along his crack. He begs for it, whimpering, as she finally pushes inside, fucking him roughly. She laughs at his pathetic moans, loving the control she has over him. She edges him, bringing him close to orgasm and then stopping, denying him release until she's ready.
