She settled down comfortably on your face, and the scent of her rear, while not as gross as you expected, certainly made you cringe. A wet, sputtering fart erupted from her puckered hole, giving you a preview of what was to come. Nicole's breathing became more burdened as she readied herself for her release. Accepting your fate, and deciding to at least do your job as best as possible, you bring your lips up to her furry asshole, and insulate her dirty entrance. Feeling this, your friend smiles and let's herself relax a little as her stomach rumbled for relief. The world seemed to slow down. It was like everything was coming into perspective as you were about to become closer to Nicole than you had ever wanted. You felt like you could sense everything: the fecal matter pushing through her bowels, the muscles contracting in her digestive tract, the gas ready to make its escape, and even her heartbeat racing alongside yours in nervousness over what was happening. That's when it happened.
With a sludge-like sound, her asshole opened and a liquid mass of shit dropped past your lips and into your waiting mouth. Nicole whined a little, as apparently her diarrhea was burning her sensitive pucker. Though, that paled in comparison to the burning on your tongue. You don't know what she ate, but it must have been spicy as the watery poo stung the inside of your mouth like hot sauce. The flow ceased and you were left with a sizable amount of canine excrement resting in your mouth. Just then, Nicole lifted up a bit to make it easier for you to breath.
"Oh, I'm really sorry. I didn't know I was gonna have diarrhea like that! I hope it doesn't burn too much." Nicole said apologetically as you swallowed her shit, feeling its heated form move down your throat. You gagged some more from the horrid taste as the smell finally hit you, and your nostrils were filled with the stench of digested meat and other foods. Soon, Nicole spoke up again, "I think I can hold out a little longer until I unload again. Do you want me to go now, or give you a break?"
Your mouth coated in her dung, you whimpered, "Ju-just get it over with."
"Alright, I'll try not to over do it, but my gut feels like a hurricane is brewing." Nicole replied as she got herself lowered onto your face again, her furry cheeks blocking any light. You reapplied your lips to her sphincter, though much more hesitantly this time. She gave a mild grunt, and the flow started up again. A pasty, pudding-like substance invaded your abused mouth once again.
This treatment lasted a solid ten minutes, with you swallowing anything she released. A couple of times Nicole thought she was done, only to grab her tummy and bear down again. Despite how disgusted you were, it still bothered you to see her in so much distress. Nonetheless, that feeling was suppressed by the overload your senses were experiencing as wave after wave of her disgusting filth was forced down your throat. Eventually, she finished and started to pant, tongue hanging out, in the sheer bliss of getting that laborious task over with. You swallowed what was left on your tongue as she began to stand up.
"Oh, I'm so happy you went through with that, not that you had a choice. And I'm really sorry about how sloppy it may have gotten." Nicole said, squatting down next to you. "What did you think?"
"I think that was disgusting. My mouth still tastes like shit, which my teeth are probably covered in, and I smell like an outhouse!" you snapped back, only to watch her sink to the floor, her eyes looking sorrowful.
"I'm...I'm really sorry. I mean, growing up, I guess I never really gave it much thought when I used a slave as my toilet." Nicole squeaked out, with her ears flattened. "But you did a really good job, and you have no idea how happy I am to have you living here with me now."
You saw the sadness in her eyes, and scooted closer to her. Putting one hand on her shoulder, you replied, "Listen, what just happened makes me want to puke, but it was going to happen one way or another, and now, we're closer than ever. I hate being your toilet, but I guess it's better than being some random bitch's latrine."
"Yeah, and I hear guys get used to it with practice. Eventually, with the right amount of patience and care, they grow to love it." Nicole reassured you, "Maybe, I could give you a little reward for doing so good..."
"Uh, what did you have in mind?" you asked, unsure of what she could be thinking.
"I was thinking I could...."
