A mistress, in her power, pins her male slave between her thighs, her legs a vice around his neck. She grinds her hips, applying pressure, as he struggles to breathe. "This is what you live for, isn't it, slave? To serve, to choke, to be humiliated?" she purrs. She releases him briefly, allowing him a gasping breath before resuming her cruel scissor hold. His cock, trapped in a chastity device, strains against the confinement, a futile attempt at release. She smiles, enjoying his futile struggle.
