Mistress Gaia did not like how petty her slave was and she had to do something to make sure he changed that behavior. The mistress felt that the best way to do that was to strip him naked and tie him up after which she whipped him on the butt repeatedly until it was all red and in pain. Needless to say, he was never petty again after that whipping.
Lady Aurelia likes sex. She, in fact, can't do without it. That is why she did not like the fact that her boyfriend was masturbating. She felt that if he continued doing so, she is the one who will be left with the short end of the stick. She did not want their sex life to be affected so she whipped his naked butt and made him promise to stop doing it.
Mistress Gaia and her room mate took their neighbor to their torture chambers for making noise for them by playing loud music. He was a nuisance and it was high time he was taught a lesson. The mistresses rode him like a horse and then whipped his naked body together. The mistresses had fun beating him up and ignored his cries of pain and him pleading for mercy. He learned his lesson.
