You used to be a normal Human boy, things were always the same old boring stuff, wake up go to school, do your homework, eat and sleep, go to the bathroom if you needed to, go to the doctor if needed and all that other stuff but eventually that will all change soon, something incredible is about to happen to you.
You woke up & immediately felt something was off. You feel pain from lying on your back, it feels as if there is an extension on your upper butt and it is being squished by you sleeping on your back. You got out of bed & went to the bathroom and closed the door. You unzipped and took off your pants and underwear, looked in the mirror & what you saw scared you. You had a 174 cm long naked hairless bareskin white skinned human tail the same color as your white skin on your butt as well as the same color of your white skin on your entire body protruding out of your lower back and upper butt, just above your human anus. "What the Hell?!" You yelled shocked looking at & touching it. It was real as you could feel your hands on it. Then your tail starts to wag excitedly like it enjoys being touched. "AAAAAHHH!" You scream. "What are you screaming about?" Your dad asked you. You try to hide your tail in your pants and underwear but it is too long to be hidden in your pants and underwear. He opens the door and sees your tail and he says "You always were a human with a human tail" He said. "I'm not supposed to be!" You yelled at him confused by his reaction. "You've always had it." He told you leaving the room. "No I haven't!" You told him.
If you have to poop, then it is even harder now since having a tail means you must sit on the toilet just right so that you don't hurt your tail by sitting on it and squishing it which would cause you to feel pain and you must make sure that your tail is not in the toilet bowl so that it does not touch the cold water and make you shiver. You must also be careful not to poop on your tail because if it you do and it is left on there for too long then it can cause an infection which will feel like the feces is burning and eating your tail which will hurt you and cause you to feel pain. If you do end up getting toilet water or feces on your tail then you will have to immediately clean it with toilet paper so that it does not become chilly and hypothermic or dirty and infected.
Later you checked your Student ID picture (for some reason) & got a shock. On it your student picture showed that you had a 174 cm long tail protruding out of your butt. WTF?! You were forced to go to school & everyone you told about your Human tail didn't think it was odd you had it. It was normal to them you had them. WTF?!. What's weirder was all your pants & underwear was modified to have a hole in them for your human tail. Later at Biology and Anatomy class you are asked to strip naked and you are forced to, you try to cover your bare anus and tail with your hands but you are forced to let the rest of the students see them and they inform the class of your unique biology and anatomy they are even allowed to probe your anus and touch your tail and both actions cause your tail to wag excitedly and happily as if you enjoy it, but you don't, Your tail betrays your true feelings, that you hate being touched by your tail and anus as you feel like they are your private parts. Later you were sitting at lunch with your friend Max. "What's wrong [your name]?" He asked you. "I'm a human and yet I've got a tail." You told him. "You've always been like this." Max informed you. You sighed "And you seem to remember me always like this like everyone else.
Eventually you return home [God. I must look like a freak, a Human with a tail just above his anus. And no one sees any of the changes as odd. Infact everyone remembered me as always that way. And reality seemed to be changing to reflect that. What do I do? Is there anything I can do? Why is this happening to me? ] You thought. This was so odd & worrying to you. You cry tears out of your eyes for a long time, for many hours even. Eventually you get tired, and sleepy and you go to bed lying on your side so you don't hurt yourself by laying on your tail and squishing it which would cause you to feel pain if you did and you eventually fall asleep.
