Maria went all out for her first test. She approached Annie and told her that she could not use the bathroom, and therefore must use her pants for the rest of the day. Maria then followed Annie for the day, watching the chaos unfold.
Maria was in all the same classes as Annie for the rest of the day making it easier for her to keep an eye on her. She first saw Annie writhing in her seat during maths. Maria was directly behind Annie, unable to concentrate on the work she gazed at Annie's beautifully rounded ass. Maria noticed Annie's hands had disappeared into her crotch and that her legs were bouncing up and down.
Annie managed to survive the rest of the class, with Maria's disappointment. However as they Annie made her way to the next class Maria noticed a ever increasing wet patch appearing across Annie's ass, turning her jeans see- through.
Maria once again took a seat dirctly behind Annie her eyes fixated on Annie's rear. Once more Annie's hand had disappeared, this time to her stomach, as she felt her bowels stirring. All of a sudden there was a loud fart that errupted from Annie. Her face went a deep crimson as her classmates giggled. Her embarrasment increased as shortly followed by her fart a large turd began to push itself into her panties. Maria could see this clearly as she stared. Annie's ass cheeks separated to allow the turd to flow, tenting her panties outwards. A large brown bulge was increasing in size as she sat there. At the end of class Annie made sure that she was one of the last to leave, except of Maria of course. Annie's ass bounced comically as she ran down the hall way, the large bulge swaying side to side, spreading the shit across her ass cheeks. She reached the toilets, shortly before Maria entered after her.
Maria caught her as she went towards a cubicle and they both went in to the one. They were both tightly squeezed into the cubicle and Annie started to cry. Maria felt bad so she stayed and comforted her for about 10 minutes and she had stopped crying. Annie explained that she could not even use the toilet to get cleaned up and she was worried about why. Maria then suggested that Annie should just continue about her day normally and that she shouldn't worry about it.
