Kneeling before your mistress, your hand wrapped around your throbbing erection, you're a slave to her whims. She relishes your discomfort, your embarrassment as you pleasure yourself under her watchful gaze. "Faster," she demands, her voice laced with dominance. You comply, your hand a blur, your body tense with the effort to hold back your orgasm. She leans in, her breath hot on your ear, "Not yet, slave. You'll cum when I say so."
