Bound at the wrists, you're at the mercy of your mistress's whims. She straddles you, her skimpy lingerie teasing your bare skin. "You're going to make yourself cum for me," she commands, her voice a seductive growl. She takes your hand, wraps it around your straining cock, and begins to move it, showing you exactly how she wants you to pleasure yourself. "Faster," she hisses, her hips grinding against yours, her own arousal evident. She leans down, her tongue flicking out to lick your neck, her breath hot in your ear as she urges you closer and closer to the edge. "Cum for me, my pet," she whispers, and you obey, your body convulsing as you spill over the edge.
