A bisexual siren finds herself in a unique predicament, her mistress commanding her to pleasure another woman while she watches. The siren's tongue dances expertly, bringing the other woman to climax, her mouth filled with her new lover's cum. But her mistress isn't finished; she forces the siren to taste her own pleasure, pushing her head down until she swallows every drop, her eyes filled with a mix of humiliation and exhilaration.
