It's December and that means it is Christmas time at Pleasure Island and the amusement park has changed to reflect that, the rides are replaced with Christmas style attractions, where you can go to visit Santa Claus, sit on his lap, tell him what you want and how you might get it for Christmas, Go to the Reindeer Pens to pet the Reindeers, give gifts whether genuine or pranks as in the White Elephant Gift Exchange. Build Snowmen or Snowforts and knock your opponent's down, or you can pelt each other with Snowballs. This sounds like quite an exciting place, this Pleasure Island sounds more like a Paradise than ever. But you don't know it but you are in Great Danger when you are on this island.
You didn't know about it while you were on the boat with the other boys and you still don't know about it now, even though you are currently on the Island with all of the other boys, but when you misbehave on this island, you start to act like a Jackass, but since it is Christmas Time on the Island, Jackass does not mean a Donkey this time, Jackass only means a Naughty Jerk, and the more you misbehave the more you will change into a Female Girl Reindeer Doe. Right now you are a human male boy, but if you succumb to Pleasure Island's Magic and Curse, your body will get affected, slowly but surely and more and more.
First you will grow a Reindeer Tail just above your Human Boy Anus, then the next step is that you grow fur all over your body that you look like a hairy human. Then your face will stretch into a muzzle, your ears into Reindeer Ears, then your Hands, Feet, Arms, and Legs will turn into Hooves. What happens after this is that your Clothes get destroyed leaving you naked, then your Testicles will turn into Ovaries. Your Scrotum will swell into an Udder and your Penis will turn into 4 and into Teats instead of remaining a Penis. You will also get a Vagina just below your Anus meaning you will not be a Human Boy anymore nor will you be a Reindeer boy either. Your navel or belly button, or bellybutton and your private parts including your udder, teats, vagina and anus will turn into that of a Female Girl Doe Reindeers'.
After all of these happen, you will be unable to stand on your rear legs alone and will be all four. Then you will lose your Human Mind. If it progresses a little after that, then you will be stuck like this forever. And if progresses too much after that, then you will be unable to escape and you will collapse, faint, pass out, lose consciousness, be unconscious, and be kidnapped and sold to the North Pole.
Also once you are seen with a Reindeer tail just above your human boy anus meaning the changes are starting to happen to you, the Pleasure Island Staff and guards will try to kidnap you, if they succeed, You will gradually, slowly, but surely turn into a naked female girl reindeer doe and eventually be sold to the North Pole.
If you escape the island and you get back to your home when you start changing you might turn fully back as a fully clothed human boy then again you might not. You might be a fully human boy, or a fully human boy but naked, or you might be a mostly human boy with just a Reindeer Tail on your butt just above your human boy anus, a Furry Human boy with a Reindeer Tail, a Human boy with a Reindeer Face, fur and Tail, etc. Or you might even be a naked Female Anthro Reindeer with your Private parts exposed, a Feral Reindeer with your Private Parts exposed, or even A Complete Reindeer in both Body and Mind with your Reindeer Body, Fur, Face, Ears, Hooves, Navel or Bellybutton or Belly Button, Udder, Vagina, Anus and Tail, Clothes-less, Naked, Nude and Exposed.
