Keli lay in a pleasant post-orgasm daze, stroking Fifi's hair and thinking about what a wonderful pet her roommate made while Fifi made little happy noises in her throat. "I should do something for her." she thought.
Keli unhooked her bra. "Joe" she began, "Fifi isn't going to be wearing anything, and I'm a little creeped out by having a guy as my bra. But don't worry, I've thought of what to do with you." She gave an evil smile.
"I wish that Joe be transformed from a bra into a red plastic waterdish with the word "fifi" in big gold letters. I wish that he take pride and satisfaction in being a useful household item rather than a generally useless male, and that he feel intense, quasi-sexual pleasure when Fifi drinks from him." She picked up the red plastic dish that had appeared on her chest. "You're going to love Fifi's tongue action."
A few minutes later Keli was looking down at Fifi, on her hands and knees lapping up water from her new dish. When Fifi finished, she made anxious noises while glancing at the door.
"Oh, you need to go?" Keli wished for a leash and collar for Fifi. It was time to show her new pet around the neighborhood.
