Bound and blindfolded, the sub's senses heighten as Mistress's commanding presence fills the room. She slips on a strap-on, tracing its length along his skin, sending shivers down his spine. With a swift thrust, she pegs him, his moans echoing in the dungeon. Her grip on his cock is firm, expert, bringing him closer to release. She leans in, her voice a low, dominant purr, "You will cum when I say so, sub." His body trembles with anticipation, awaiting her command.
