Bimbo-Midas, written my Doctor MC, brings us the tale of a young man who is given the power to have any and every woman he wants with a simple touch, thanks to a wish granted by a leprechaun.

“The red-haired man asked Jimmy, “What manner of lady love would you have, if you could?”
Jimmy answered the question with scratch-where-it-itches honesty: “Girls with hot figures, and hot hair, and makeup, and clothes. By hot, I mean _super-hot_—they look like strippers and porn actresses. Girls who will do anything and everything with their boyfriends—anytime, anywhere, doesn’t matter if someone is watching. But while they’re totally faithful to their man, they don’t get upset if their boyfriend has another girl on the side. In fact, they’ll have a threesome with that other girl, if that’s what their boyfriend wants.”
Jimmy did not know that the red-haired man was a leprechaun, or that the leprechaun owed Jimmy the grant of a small wish. All Jimmy knew was that afterward, every woman he touched—even accidentally—become more bimbo-like each day, and that Jimmy got _all_ the benefit of this. Jimmy’s control-freak girlfriend had no problem with his enjoying bimbos—because she was becoming a bimbo too.“

The magic and the one-man-uses-all-women (rather than all men use women) make it a bit left of pure freeuse genre, but it’s close enough to have fun with with this 18,400 word long novella.
