You wake up the next day and hope that yesterday was a nightmare and that you are not a girl. Nope, you still have a urethral meatus, clitoris and vagina just in front of your anus. You brush your teeth and go to school naked.
You go to anatomy and biology class and have to go to the front of the class and face the blackboard so that your naked butt is facing all of the other students, suddenly you feel severe pain in your butt, causing you to bend over and exposing your anus, clitoris, urethral meatus, labia majora and Minora, and vagina for everyone to see, your coccyx or tailbone part of your spine or backbone decides to unfuse, lengthen and have extra vertebrae, it also twists and curves. It breaks it’s way out of your butt’s skin. It feels like a corkscrew bottle opener or spring is trying to find it’s way out of your butt, but it is not that, it is your new tail, right now it is just bone but then it grows nerves, fat, muscle, and skin. The students are amazed by what they see and they don’t mind it in fact they love it.
You ask for permission to go to the restroom, and it is granted, you look in the mirror and see a curly appendage on your butt, it looks like a tail, it is also curly and pink. You wiggle your butt and it wiggles with it, you try to pull it to see if it really is yours, and you feel it.
“OH NO!” You say to yourself, it really is your tail, you have a naked hairless bareskin pink curly pig’s tail on your butt just above your anus.
You still have to go to all of your classes, but you have be at the front of the class so everyone can see your tail. The other students. Pull on your tail and you feel pain but also orgasmic pleasure from that too. "This feels good you think to yourself" But then you shake your head and try to snap out of it. "This is wrong. This is very wrong!"
You later eat dinner. You are still eating the same thing that you always eat, then you go to bed with your vagina, clitoris, urethral meatus, anus, and pig tail exposed. You don’t know what you are going to do the next day.
