Bound and gagged, the slave's eyes gleam with anticipation. Her femdom mistress teases her, running a vibrator along her quivering lips before pushing it into her mouth. The slave struggles, drool dripping, as the toy stretches her jaw. Her mistress laughs, pushing it deeper, making the slave gag. The vibrator hums, sending waves of pleasure through the slave's body, her muffled moans echoing in the room. The mistress watches, aroused, as the slave's body writhes, helplessly chasing her orgasm.
