A bisexual fantasy unfolds as a submissive woman, hungry for new experiences, is introduced to a bi-sexual mistress. The mistress, with her massive strap-on, teases the sub's mouth, rubbing the slick head against her lips before roughly pushing inside. The sub, eager to please, takes it all, her mouth stuffed full, as she's used for the mistress's pleasure, their threesome fantasy playing out in filthy, explicit detail.
