Christina Carter, a seasoned sub, is bound and gagged, her massive tits heaving with anticipation. Another woman, a dominatrix, teases Christina's ass, running a wet finger along her butt crack. Christina's eyes widen as the dominatrix inserts a thick plug, stretching her asshole. Soon, the dominatrix replaces the plug with her own strap-on, thrusting deep into Christina's ass. Christina moans, her body trembling as she's fucked hard, her pussy dripping with lust.
