Mistress Coral finds sissy slave Erica naked and set up on the fuckmachine, waiting to be used. She starts playing with her, fucking her ass, sitting on her face, teasing her about her predicament, and having her way. Little do they know that Mistress Mercer would find them so soon... and she's not happy that Coral has been playing with her toy without permission. Coral gets collared, cuffed, and her thong is pulled aside to be fucked by a large blue strap-on on top of sissy Erica's face as Erica continues to get railed by the machine and queened. Mercer's sex slaves pleasure each other in 69 while their pussies are destroyed until a messy, gushing, squirting climax, where they both end up covered in cum.
