In a dimly lit dungeon, a confident Mistress awaits her new pegging slave. She's dressed in all black, her heels clicking on the stone floor as she paces, a strap-on harness already snug around her hips. Her slave, a muscular man, is bound and gagged, his eyes filled with a mix of fear and anticipation. She walks around him, admiring his body, before selecting a thick, veined strap-on dildo. She lubes it up, then positions herself behind him, her strong hands gripping his hips. Slowly, she pushes the dildo into his tight ass, a low growl of pleasure escaping her lips.
