A dominant lesbian mistress exacts her punishment on a helpless blonde slave, forcing her to masturbate to orgasm. The submissive girl, bound and at her mistress's mercy, tentatively begins to touch herself, her fingers rubbing her clit tentatively at first, then with more urgency as her arousal grows. The mistress watches, her eyes gleaming with satisfaction, as the slave's body responds to her touch, her nipples hardening, her breath coming in short gasps. The mistress increases the intensity, her hands and mouth joining in, pushing the slave towards an explosive, humiliating orgasm.
