In the dimly lit dungeon, a trembling slave awaits his Mistress, bound and gagged. She enters, her heels clicking on the cold stone floor, a cruel smile playing on her lips. She straddles him, her powerful thighs clamping around his neck in a vice-like grip. He gasps, struggling for air as she grinds her crotch into his face, her arousal evident. She leans in, her breath hot on his ear, "You'll learn to breathe through my pleasure, slave."
