"This curse is bullshit, but I'll choose dare." Jen said, wondering how a fourteen year old pervert could still believe that curse exists. Although, he is a pervert, so he might want to use the curse for more than just 'run into mommy and daddy's room and tell them you want to be a cow for Halloween'.
"You chose dare, huh, well in that case, for your dare you will begin to poop in places you aren't supposed to. You will start by shitting in front of the toilet, over the next week you will start to shit in sinks. After sinks, you will shit in bahtroom garbage cans, then go to the urinals in the boys room to poop, then just outside the bathroom. Then, your new toilet will be different depending on where you are. If you are at home, or in another place with beds, you will seek out a bed. If you are at school, you will go in someone's locker. If you are anywhere else, you will just shit in your panties wherever you are. Then you will seek out dressers or closets and drinking fountains. You will continue to progress away from the bathroom, and after a year you will just shit on the ground. You and I alone will notice these changes, and you will know that you should be going somewhere else, but will be unable to remember where or how. Even if you ask someone to show you how they use the bathroom, you will believe they are doing to wrong. You will give the curse back to me with the dare 'I dare you to go on a date with me tonight - my treat' whenever you receive it. You will respond to it how I want you to, however you will believe you made that choice."
"Whatev... Transform or Dare?"
"Dare"
"I dare you to go on a date with me tonight - my treat"
"Ok, Transform or Dare? Choose Transform."
"Transform"
"You will produce enough poop per hour that every hour, you feel like you are going to explode. You will also be able to comfortably hold five times the amount of shit as a normal person. Umm... Your ass will double in size, and you will grow a fully functional skunk tail that you cannot control." Kyle says, adding some more external features.
"Transform or Dare?" Jen asks, under influence of her dare.
"D-Dare!" Kyle stammers, cought off guard by the speed of the question.
"I dare you to go on a date with me tonight - my treat"
Kyle hangs up and Jen feels tingling in, on, and above her ass. She feels more weight on her ass, turns, and sees her new tail, which promptly sprays her in the face, making her gag and choke. The tail, while not under her control, feels this and makes a note to not spray the thing it's attached to. Eyes still watering from the stench to the face, Jen resumes the task she was doing. Just looking at her ass it was easy to tell it had grown considerably. Recalling the curse, she now had an ass twice the size of the one she was used to. She felt the familiar pain in her gut telling her to take a dump. She could usually ignore it for a few hours, but decided to follow her body's advice and take a shit because she felt fit to burst and wouldn't see another bathroom until she got to school. Entering the upstairs bathroom, she took her usual spot in front of the toilet and started to shit, logs dropping against the cool tile of the bathroom. Halfway through, Jen noted two things. First, this is an insane amount of shit, and second, wait am I supposed to be shitting here?
Jen could not think of where or how she should use the bathroom, was it how she was squatting? No, that shouldn't matter. Was it where she was? No, she always crapped there. She thought that she was supposed to do something with the toilet, but then the 'rational' part of her mind told her "of course, you have to stand infront of it."
Two minutes later, she had done he business, wiped, and left the used TP neatly folded into a flower on top of her pile. She exits the bathroom, eats a small breakfast and catches the bus.
Her tail does not know what to make of so many people crammed into a metal tube and ends up spraying everyone the entire time. She sat next to her friend Susan as her tail figures out that not everyone is a threat, and will now only spray people approaching from behind her. Susan and Jen chat idly, about boys, fashion, music, whatever, when Jen brings up the odd call she got this morning. "So that kid really used the curse on you?" Susan said, completely serious.
"Yeah... Wait, you believe the curse?" Jen said, surprised.
"How do you think I got this?" She said, pointing to the unicorn horn on her forehead.
"You got it surgically implanted when you were three, remember? When you started school, everyone wanted to touch it and would ask you questions about it." Jen recalled, even though Susan had really gotten it at a slumber party last week.
"Yeah, I guess." Susan said, now accustomed with both her new horn and history. "But what were your changes?"
Jen tells Susan her curse, and the fact that whenever she gets the curse, she has to go on a date with that creep.
"Well the date part isn't so bad, you don't have to like him or anything, but the curse is weird. So you are going to be like, reversing potty training or something? But you've always shit right in front of the toilet, and your ass and tail aren't any different either, although it may just be the reality altering to make it seem normal to me..."
