It's common knowledge that there are more than a few Nurse Joys in the world, but this one was unique in more ways than one. For one, she was considerably fatter than any other Nurse Joy one might have seen through their travels, weighing in at nearly five-hundred pounds of flab. Secondly, she had a cock... And quite an impressive one, at that, roughly comparable to a human arm in length and thickness. And thirdly, though she worked in Virbank City, she didn't run the Pokemon Center. No, her rather disgusting manners, obscene lewdness, and all-around shady morality had consigned her to underground work, helping those who would rather not be identified later. In a dingy basement, she reclined behind her counter, eating a massive, greasy hamburger with all of the grace and delicacy of a Tauros in heat with one hand, and playing with her fat, musky balls with the other. Nobody came down here unless they were either terribly lost or knew what to expect from Joy. Belching loudly, she looked over at the Pokemon she had helping run her shifty clinic. The Chansey, people would expect, though she was a great deal surlier than most... The Garbodor and Muk, however, would be oddities behind any other Pokemon Center counter, and definitely a biohazard.
Scratching her sweaty pits, Nurse Joy continued not giving a fuck. Pokemon under her care always came back healthier than before, at least physically. Oh, sure, maybe there would be a few mental scars...
Suddenly, there was a knock on her door. "Ugh... *phwwwrRARRRP* I've got to train one of my Pokemon to answer that, sometime..." Grumbling as she had to interrupt her food-and-masturbation session, she hefted herself from her chair and waddled over to the door to see who was there.
