Master and Mistress already had another slave living with them when i moved in. Gina told me Master and Mistress were very cruel and she was going to revolt. She wanted me to join her in that. But i was just discovering that i enjoy being trussed up, suspended from the ceiling, and having hot wax dripped on my clit and nips. Gina revolted alone. She tried to overpower Master and Mistress. Master and Mistress told her, "BDSM slaves do as their masters want...or they get punished." Then they put her in a rack. They told her, "BDSM slaves are obedient...or else." They they put strong clamps on her nipples that really hurt her. Then they fisted her cunt and told her, "Do you understand now that you two are the BDSM slaves and we are the Masters?" Gina said, "Yes, Mistress,” but Mistress pussy-spanked her anyhow.
