A submissive man, eager to please his dominatrix, finds himself in a sloppy, degrading situation when she commands him to suck her friend's cock. He hesitates, but her stern gaze and the promise of punishment force him to comply. Kneeling, he takes the stranger's dick in his mouth, sloppily sucking and gagging, as the mistress watches, criticizing his technique. His humiliation complete, he's left with a mouth full of cum and a new understanding of his limits.
