"Isn't that right, Shitlips?" Mistress Eva gave Claudia a wink and returned her stern stare back to Shitface.
"The cows have been grazing all day," she said with a sinister chuckle. Claudia was now starting to make sense of things.
Master Robert suddenly chimed in as well. "Those laxatives should take 15 or so minutes to take effect. In the meantime you can start cleaning my ass," he demanded from Claudia who proceeded to wipe the shit off her face with her hands and then lick them clean. The less shit she had on her face, the easier it would be for her to clean Master Robert's ass. While Claudia feverishly polished her designated asshole and inner buttocks with her tongue, Mistress Eva unchained Shitface from the toilet bowl and crawled her behind Claudia.
"Let's give you an hors d'oeuvre of human waste before you're inundated with cow shit," she said as she pressed the girl's gaping mouth against Claudia's anus.
Claudia was so busy with her cleaning duties that she didn't realize until she felt a pair of lips press against her anus. She heard a little sniffle from the girl and tried to work out if she was crying. In the 24 hours leading up to her return to Mistress Eva's farm, Claudia had indulged on her favorite foods for she had no idea when she'd get a regular meal or what it would consist of. She felt sorry about the inevitability of what was to come as Shitface's tongue washed over her asshole. The laxatives were beginning to fulfill their purpose.
I'm so sorry, she thought as she had to pass gas into the girl's mouth. Ironically, Master Robert did the same to her and she couldn't imagine hers being as foul. She continued cleaning until some aggressive bowl fluctuations interrupted her. Good God, this is going to come out violently, she worried. Claudia could tell the girl was definitely crying now, or at least sobbing, she could even feel tears running against her ass cheeks. She didn't know what to make of Shitface, at times when they shared Master Robert's shit she appeared eager and enthused, other times she had the demeanor of a child separated from her mother.
Still the girl's tongue rimmed Claudia who figured there was no point holding the inevitable and released a fierce eruption into Shitface's mouth. She couldn't see the mess, but she could feel very moist feces on her ass cheeks and could only imagine the state of Shitface's mouth as she listened to her gagging and coughing. Mistress Eva had held her head pressed against Claudia's exploding asshole the entire time. She really hoped Shitface wouldn't hold this against her.
Once Claudia had pushed out the last of her excrement, Mistress Eva swapped their positions. Claudia caught a glimpse of Shitface's face, masked in brown. On the floor was a muddy mountain of Claudia's shit and it didn't look like Shitface had eaten much, if any, of the 'feast'. Unlike Shitface, Mistress Eva didn't bother holding Claudia's face against the girl's ass, instead she left her on her back with her face in the drop zone beneath Shitface's ass. Shitface was getting most of Mistress Eva's attention and Claudia was getting slightly jealous. She lay in wait feeling as though she was getting off lightly, Claudia considered the possibility that Mistress Eva underestimated how much she now craved fresh shit to consume. She's taking my diligence for granted, she thought to herself, but I guess a good slave should be. It was all a bit confusing for Claudia who, despite how far she'd come, was still essentially new to the game. At least now she was about to get some more scat.
Deciding to take the initiative, Claudia got back up on all fours nose-dived into the girl's ass. She cupped her lips over her sphincter and was instantly greeted with a very wet sounding fart. It sprayed fecal mist into her mouth; which she felt and tasted. The suppositories had taken rapid action, but it had moistened the stool considerably; close to diarrhea. Against her lips, Shitface's ass pulsed, another splutter was followed by some runny brown mucus. Claudia held firm as it trickled over her bottom lip and teeth. She had her hands around the girl's ankles, so that she moved in unison with her as she sometimes squirmed. A little more liquid shit oozed out from the asshole and this time Claudia mopped it up with her tongue. Shitface, still cleaning Master Robert's ass, moaned at the sensation of Claudia's tongue wiping over her anus.
Eventually the floodgates opened to release a river of brown into Claudia's mouth. It was like the dam had collapsed and Claudia couldn't keep up with the overflow. It sprayed out like a hose. Claudia gargling while trying to swallow as much as she could, but coughed and snorted a large amount of diarrhea through her nose, squirting it onto Shitface's ass cheeks. Lots of shit fell on the ground, angering Mistress Eva. "Fucking useless," she scowled. She grabbed Shitface by the leash and began leading her out. "Off to the barn with you," she sang. "After some forced cow shit, our turds will taste like chocolate."
"You'll sleep here Shitlips," informed Master Robert. "Your dinner has been served. You'll find it on the floor around you."
"These tiles better be fucking spotless next time I come back here," added Mistress Eva.
