Mistress, a mature seductress, enters the room, her latex outfit squeaking with each sultry step. Her eyes fixate on her bound slave, hogtied and helpless. She smirks, knowing the power she holds. She runs her hands over her body, teasing him, before stepping onto his chest, her heels digging into his flesh. She leans down, her breath hot on his face, "You like this, don't you, slave? The anticipation, the helplessness, the fear?" She slides down his body, her heels brushing against his bound cock, making him twitch. She reaches his balls, now tightly bound, and presses her heels onto them, watching his face contort in a mix of pain and ecstasy.
