As class ended the room emptied, it was late and the professor ended class early. He shouted to the two girls who hadn’t left yet as he walked out the door.“The door’s already locked, just shut it when you leave, and don’t forget about the test on Friday!”The girls nodded and continued packing up there belongings. The darker haired girl tried not to glare at the blonde next to her that was babbling about something as if she cared.“Don’t you think he’s a little cute? I mean, I know he’s a bit older, but he has a certain… I dunno, something..”“A dick?” The brunette said with spite.The blonde scoffed “Ech, what is that supposed to mean?”“Don’t pretend like that isn’t what your thinking about, you hit on everything that moves Emma, including my boyfriend…”“Ahhahaha this… this is about David? I’m sorry Kelly, but it isn’t my fault that he isn’t into you or your flat ass!” Emma grinned and went back to packing her bag.Kelly saw red, she ripped a heavy book from her bag and flipped through it, skimming down the page before finding what she needed. “You know Emma, not everyone can be a blessed as you, I don’t know how you can even contain that horse’s ass of yours in a pair of pants it’s so big.” The brunette started to mutter something quietly while Emma turned and spoke to her.“Kelly, you really need to check yourself, if you can’t hold onto your man I can’t be blamed if he wants my huge….” She stopped talking, he attention drawn to her ass. It felt like it was… no it couldn’t be… was it… growing? She felt her pants get even tighter, the fabric of her jeans could barely contain her. In addition to the strange sensation of swelling, there was a small pain around her tailbone, and Kelly was chanting something like a freak. “What the hell are you doing Kelly.. *unnnnhhh* What are you… doing to me?”Kelly grinned and continued to chant, watching with glee as Emma pants ripped into shreds, her voluptuous ass spilling out with a jiggle. Emma pulled down her panties before they got stuck on her, and as she got them to her ankles she felt something tickle her arm, it was her… “Tail?!?” She grabbed it and pulled, it yanked at the base of her spine above her ass and she tried not to yelp in pain. Her ass was still getting bigger, it really was starting to resemble a horse’s ass in size now. Instead of getting mad she started to laugh.Kelly lost concentration, why the hell was Emma finding this funny? Emma stood up and took a step toward her, then turned and whacked her with her huge ass. Kelly wasn’t expecting that and was sent to the floor roughly, the book falling at Emma’s feet. Emma bent down and grabbed it, her gigantic ass only a foot from Kelly’s face. It was so big, Kelly was in awe of her own handiwork.“You know Kel, if you thought everyone was trying to get on my ass before, wait til they get a eyeful of this!” She squished her ass into Kelly’s face and laughed as the brunette pushed her away spitting out hair’s from Emma’s horse tail. “Don’t fret about how marvelous my ass is, or how much nicer of a tail I’ve got than you could ever have, I’m sure I’ll find something in here that you will love to be turned into.”“N-no… G-give me back my book!”“Nah ah ah, not yet flat Kelly, after I get back from buying some new pants I’ve got some reading to do tonight, and a big comfy ass to sit on, so I think I’ll be keeping this for a while, and your boyfriend too. I don’t think he’s gonna be able to pass on this.” She admired her butt for a moment and walked over to her bag to grab her mercifully long coat, her massive ass swayed hypnotically and Kelly just sat on the floor watching it. Emma grinned, even Kelly couldn’t resist looking at it, this was going to be fun. She walked to the door and stopped, throwing a last glance to her dark haired rival before leaving “David always did have a thing for big butts…” She spanked her ass suggestively and left. -- source link
