In a dimly lit dungeon, a stern mistress orders her bound lover to focus solely on her pleasure. She paints his lips with her arousal, then forcefully pushes her wet cunt onto his face, grinding her hips. He struggles, gasping for air, but she doesn't relent. She reaches back, spanking his balls, making him wince. "You'll learn to breathe through your nose," she commands, fucking his mouth with increasing fervor. His muffled moans vibrate against her pussy, driving her closer to orgasm. She smirks, "Good boy," before pushing him deeper, seeking her release.
