The woman's voice is a whip-crack, "Start jerking off. I want to see you follow my instructions." The man's hand wraps around his eager cock, his strokes becoming faster, more urgent under her watchful gaze. "You're close, I can see it," she purrs, her eyes never leaving his flushed, straining face. "When you cum, you will say 'Yes, Mistress' and swallow every drop." He nods, his breath coming in ragged gasps, "Yes, Mistress," he chokes out as he cums, his body convulsing as he follows her command.
