The dog anthro raised a brow curiously at the equine anthro that just walked in on her. She was having a normal day at her home when this horse just barged in. She held a phone with her, ready to call the police, but the horse didn't hold anything that looked dangerous. "Okay, 'why' did you just kick down my door like that?"

The brown equine anthro crossed her arms. "My name is Myu. Your name is Samantha. I'm working on writing stories, and congratulations. Someone paid me to have some fun with you. That said, we're going to have ourselves an interesting time together."

Samantha blinked rapidly. "Uh, you didn't..." She wondered how the horse knew her name. She shook her head and began to dial. "I'm calling the police." As she dialed the number, she heard nothing on the other end. Something cut her phone cord. She turned from the phone back to Myu. "You...you didn't."

"Well, we only have a thousand words to work with. I know most of your kinks, and I have a general idea of who you are." The equine put her hands on her hips. "You're into filth and grossness, which is good because that's the theme tonight. So let's get right to it." She turned around and took off her kimono. She revealed her brown hide covered body and large cock to Samantha, as well as her bare ass. "This is going to involve crap, and a lot of it. Also, I don't mean 'random junk'; I mean the actual waste that comes from the ass."

Samantha looked at the bare equine ass, and then at Myu. Myu was right. Samantha was into filth, and an extreme amount at that. She was confused though. "You're just...you're just going to get right into it? I mean, you know I'm a dom, right? I don't get my face shit on. I shit on other's faces." She spoke very bluntly.

Myu suddenly leapt upward and landed her bare equine ass right on Samantha's face. "Oh I know, but this is my story, and nobody's going to make me sub!" She paused. "Unless they pay me enough money, then I'll consider it. Anyways, we've wasted more than enough time." She took a deep breath, and unleashed a fart.

Samantha's eyes widened. The dog anthro tried to push herself away from Myu, but for some reason the horse was just too strong. Myu's ass and her fart smelled like a rancid old barn. "Umph!" She wanted to open her mouth and speak up, but if she knew what Myu was about to do, she knew better than to open her white furry muzzle. She wondered how Myu could be stronger than she could, and how she leapt so high! Samantha was more than eight feet tall, and Myu was barely six feet.

"I know! You can barely contain yourself, right?" She wiggled her ass. "And I can't contain myself." Her anus widened, and she began to shit on Samantha's face. As she was a horse anthro, her shit looked just like horse droppings. It made it easier on Samantha as much of it rolled off her, but it also created more stains on her clothing as it did. Myu crapped for a good minute before she pulled off Samantha. "There you go, you dirty dog." She teased.

Samantha pulled herself up and ripped off her clothes. She didn't care if Myu saw Samantha's furry naked body. "Dammit!" She shouted angrily. She glared at Myu and bared her teeth. Filthy kinks were one thing, but breaking into her house and shitting on her was another entirely. "Fuck you!"

"Promise?" Myu batted her eyes sweetly before she grinned at her. "Hey, I already said I know about you. This turns you on, doesn't it?"

Samantha scoffed. It turned her on, but she was too furious at Myu for just breaking in and just getting right to the point. In addition, she was the dominant type. "I'm so going to return this fucking favor."

"There's not enough time in the story for that." Myu waved her hand dismissively. "But there is enough time for you to shit and shit a lot while I sit on your face." She suggested.

Samantha glared at Myu. She barely knew the horse and it felt as if she were controlling her very life the moment she came into existence. "What makes you think I'm going to just let you do that?"

Myu held up her hand. "One, I have magic. Two, I'm writing this story, not you. Hence, you have to do whatever I tell you to do. Three, I can see the arousal in your face from this idea."

Samantha sighed frustratingly. She felt something in her head that told her to go along with it, and she 'knew' it was Myu's doing. She still loathed the horse. "How much longer are you going to be doing this damn thing?" She felt her stomach rumble angrily.

"Just a short while." Myu replied with a shrug. "I just want it to end on a bang. I know I want to involve transformation, but there's really no time for that sort of thing here."

Unable to hold herself back, and knowing very well it was Myu's doing, Samantha spread her large ass cheeks and began to crap on the ground with a groan. "Ugh...fine." She said with a defeated grunt.

Myu sat down on Samantha's lap this time and began to crap herself. She kissed her happily and wrapped her arms around her. "I know we just met, but I think this is the beginning of a beautiful friendship!" She wiggled her rear as she kept crapping with Samantha. "Or a very shitty one. Either way, it'll be a great time."

Waste quickly filled the floor, as well as around Samantha and Myu. Samantha felt humiliated, but she enjoyed it. She'd get back at Myu though at some point. It was just a matter of time.
