In this intense femdom session, a curious bi sub is taught the art of oral pleasure by an experienced mistress. The sub, eager to please, takes in the thick, veiny cocks of both the mistress and her male helper, gagging and choking as they push deep into their throats. The humiliation is palpable, but the sub is turned on by the power dynamic, their body responding to the rough treatment. The mistress, watching closely, guides them, her voice stern yet encouraging as they work to master the skill.
