It's test day in class and I really have to go to the bathroom. I ask my professor, but he says I should've gone before class. I can't hold it much longer and I end up peeing in my jeans. My professor calls me to the front of the class, noticing my suspicious facial expression, and everyone sees that I wet myself. My Professor reprimands me for not being a big girl and spanks me in my wet jeans in front of the whole class. Then I'm made to stand facing the wall for the rest of class with my pants pulled down. Next class he makes me put on pampers in front of everyone to insure I don't make another mess on the floor. He makes me stand at the front of the class while he lectures with the diaper in clear view so no one forgets what a bby I am. And then to my dismay, I end up peeing myself again! My Professor soon notices my full diaper and pulls me into his office. He says clearly I like wetting myself if I'm going to do it again in front of the whole classroom. I deny it but as he starts to rub my diaper I'm not sure anymore...I get diaper fucked by my professor and then I'm changed into a big crinkly adult diaper and bby clothes. I'm taken in front of the class and it's announced that from here on out I am to be the class bby.
