You are an ordinary white skinned human girl, you have been kidnapped and taken to pleasure island, as punishment for trying to resist and escape you have been stripped naked and made impossible to wear any clothes, your belly button, vagina, labia minora, labia majora, urethal meatus, clitoris, perineal raph, and anus are all naked and exposed and that of a Human's. You have no paws, hooves, fur, or any tails whatsoever. Your private parts are naked and visible for everyone to see. Before you were put on the boat, the Pleasure Island Staff to punish you for your resistantance and attempt to escape, they used magic, magical cream, and gloves. They fingered your anus and rectum and touched your Tailbone through your butthole and rectum and applied magic cream to it. You shiver at being violated this way, it feels so wrong. There are hundreds or thousands or millions, or even billions of other boys and girls that have come to this island with you. Unlike you however they are all fully clothed since they came of their own free will. You are fully Human for now. However that is all about to change soon.
You feel a lot of pain, pressure, itching, burning, and a funny feeling in your tailbone on your upper butt just above your Naked Human asshole. Your tailbone stretches out only so slightly and it becomes a tiny stubby bumpy nub that is barely seen or felt on your upper butt just above your anus, It is currently naked hairless and bareskin and it will grow longer and when it is finished growing it will be 174 centimeter long tail and it will either be a 174 centimeter long naked hairless bareskin human tail or a 174 centimeter long furry or naked hairless bareskin or scaly animal's tail either by the passage of time or the Pleasure Island Staff finding you and pulling on your Tiny Stubby Bumpy Nub of a tail on your butt. but for now it is just a tiny stubby nub bump of a tail that is barely seen or felt on your upper butt just above your pucker. The fact that it will turn into a real tail means that your spincther will eventually become your tailhole. You also feel pain for everytime your tail grows a centimeter.
It doesn't look like any of the other kids have transformed yet, you are THE very first one that has started to transform. Either they are immune to whatever Magic is affecting you or they are only more resistant to it than you are and they will eventually change later. If you can escape the island without getting caught by the Pleasure Island Staff and before your tail grows to 174cm and some unspecified period of time after that it becomes a permanent part of your body you might be able to escape as a Human Girl without a Tail meaning that if you escape this Place quickly enough and not take too long, you tail will recede back into your butt just above your anus and being fused back into your coccyx, vertebrae and Spine. But if you get caught by the Pleasure Island Staff you will be stuck on this island forever. If you take too long and your tail grows to 174cm and too much time passes after that, you will be permanently stuck with a tail attached to your body on your butt just above your naked anus even if you do escape this island. You have got to get out of here before the Pleasure Island Staff People get you and/or your tail grows to 174cm and becomes permanent sometime after that. But in the Meantime what are you turning into?
