A curious bisexual woman finds herself in over her head as she's introduced to the world of femdom. Her mistress, a stern and dominant woman, strips her bare and forces her to her knees. The bi-curious babe is made to service her mistress' strap-on, learning the art of deepthroating and gagging on the thick, veined dildo. She's humiliated, spit on, and forced to call herself a "cocksucker." But as she's pushed further and further, she begins to crave the domination, her body responding to the rough treatment.
