In the dimly lit dungeon, a bound male writhes, his eyes locked onto his mistress's every move. She teases him, her fingers tracing his chest, her nails scratching his nipples. She leans in, her breath hot on his ear, 'You want this, don't you? You want to serve your mistress.' He nods, his voice ragged, 'Yes, mistress.' She smirks, her hand wrapping around his cock, stroking him firmly. She leans down, her tongue flicking out to taste him, her lips parting to take him in, her eyes never leaving his as she sucks him hard, bringing him to the brink before denying him his climax, her laughter echoing through the room as he whimpers, begging for release.
