When Sarah Shevon's shoot with James Deen gets cancelled, she sets out for revenge by leaving cartoon drawings around the Armory depicting James with humiliating innuendos. Once he finally catches the jealous culprit, the joke is on her as she gets tied up and used for his pleasure.
A slave is "treated" to both electricity and whips as he gets it from all sides and at both ends, with two Mistresses dealing it out to him at once. Is Mistress really going to give him that piss enema? The very thought is revolting, but you'll have to watch the movie to learn the answer to that question.
