The boy's cock throbs painfully, pre-cum beading at the tip as he follows his Mistress' explicit instructions. His hand moves feverishly, his grip tight, mimicking the sensation of her wet, velvet cunt. She watches, her eyes hungry, her pussy clenching in sync with his strokes. But as he nears the edge, she orders him to stop, to tease his balls, to pinch and pull until he's writhing, desperate for release. She leans in, her breath hot on his ear, whispering filthy promises of what she'll do to him, what he'll do to her, before stepping back and leaving him there, hard and aching, a prisoner to her will.
