Going to the otherside

Batman went to work, pleasing his mistresses. That was his life now. So he set to work, using the skills with his tongue to please the possible new mistress that was to enter the sisterhood. His tongue licked the clit and moved it with an erotic touch. That gained moans from the Barbara, and started a minor flood of pussy juice. Juice that he lapped up with a joy. His new training had made his delight in the taste of the fluid.

Barbara was going into a shocked state as the potion and the skill of her former mentor were going to work on her. As this was happening, she was losing control of her concious mind. Letting the whispers of the three villainesses entering her mind, changing her.

Barbara was now realizing that she was a bad girl and that she wanted to help build a crime empire that would control the world. Under the thumb of her and her sisters. Ivy, Harley and Catwoman. And her mind altered.
