The room echoes with the smack of flesh against flesh as the submissive's hips meet Mistress X's ass, driving his cock deep into her tight, clenching pussy. She moans, her voice echoing in the dimly lit dungeon, urging him on. She grabs his balls, squeezing them as he pounds her, her own pleasure building as she teases his sensitive sack. Her pussy convulses around his cock, milking him as she screams her release, commanding him to fill her with his hot cum.
