"Knot" A Good Time to Have to Go

Feral MxF Scat Story, 8,000 words. Featuring Lena the border collie and Mikey the pointer/foxhound.

"...I swear this has never happened to me before!"

"Yeah, right. You know, if I could reach your dick I'd bite it off!" Lena the border collie glared back at her lover.

"Hey, you're not really motivating me to -"

"Are you saying you're doing this on purpose?"

"No! I'm saying threatening me isn't going to help either of us!"

"It's sure making me feel better - yipe! Ow, stop pulling!"

Lena had been in heat for a week now, and chained up in her owners' backyard every day. The fence was too high to jump, and the posts set too low to dig under, so it had been a lonely, miserable experience. At least, until Mikey found a way in. The pointer-foxhound mutt had been her frequent playmate at the local dog park for a long time, and now they'd become something more. She had to admit she had a crush on him, and in a way she was glad he was the only suitor who'd made it past the fence. It made this special.

There was just one problem. Currently Mikey was pointing with the wrong body part, in the wrong direction. His knot wouldn't go down. And he certainly wasn't a poorly-endowed mutt either. Hung like a Great Dane, Lena thought. She was exaggerating, but she was in love. And she wanted to kill him. It was complicated.

They were stuck fast, rump-to-rump, with a huge, sticky load of his cum uncomfortably leaking out into the fur around her pussy.

"I, uhh... guess it'll go down eventually on its own, right?" Mikey said nervously. But it didn't. Lena was so anxious she couldn't sit still, and every little movement kept stimulating her mate enough to keep him hard. She was trapped, the short chain keeping her in a small circle of grass that was trodden into dirt, with just enough space to reach her food dish and water trough.

"Well, good thing your owners left enough snacks and drinks to share, right?" Mikey shrugged and started to help himself.

"Hey! What are you doing? That's mine!" Lena wasn't really hungry yet, but she sure as hell wasn't going to let him eat all her food. But the way they were stuck together, she didn't have much of a choice. He was bigger, and heavier. All she could do was stand there insulting and threatening and listening to him greedily scarf her dinner.

Tears came to the collie's eyes. "Mikey, please... just stop... leave me some!" she whined.

"I barely had a few bites, I wasn't gonna take all of it! Geez!" Mikey huffed. But he turned around, finally giving her access to the food bowl. Actually, he was kind of right, even if he was a rude guest. There was plenty. It seemed like days worth. The mix of kibble and wet food had been sitting out in the hot sun for a while. It smelled funny, and tasted funny, but Lena's instincts took over, and before she knew it she was stuffed, and the bowl was mostly empty.

"Are you gonna finish that?"

"Oh, for the love of -"

It really was hot out, and in the heat of passion Lena had pushed Mikey back against her doghouse until her chain ran out, scooting it out of reach. But there was plenty of water. Even with her stomach bloated, she lapped greedily at the massive bowl until she felt like she would either burst or puke. Maybe both. Mikey drank at least as much. Before long Lena felt an uncomfortable pressure in her bladder. She didn't mention it at first, but it grew, and grew, and grew. She whined, and shifted her wait from foot to foot. She had to pee, and badly. She could hold it in all day, usually, but she didn't usually drink this much, and her bladder was bursting even though it was barely noon. And they were still tied together.

"Er... Mikey?"

"Yes, my tender, gentle rose blossom?"

"I have to pee." At least, that was the more urgent bathroom need. There was a strange feeling deep in the pit of her stomach. Something shifting, moving inside her. Maybe it was just gas, though. God she hoped it was just gas.

"Huh. So do I. Funny, I was just about to say something. Ha ha, kind of a coincidence that we'd both have to -"

"It's not a coincidence you idiot, we've both drunk about a quart of water!" Lena snapped. How was this the only dog who knew how to open a gate? He was smart in some ways, but what a moron!

"Yeah, I guess that makes sense. That reminds me, I'm thirsty too. Do you want some water first?"

Lena looked at the trough. It was still mostly full. There was no way even Mikey could drink that all at once. "No," she said. "Go ahead."

He lapped for a worryingly long time, though, and then had the fucking balls to complain that he had to pee worse now. So did she! She was ready to explode! But she couldn't! Physically she could, sure, but their legs would be soaked.

"I'm telling you, I really gotta lift my leg!" Mikey complained.

"Well then hurry up and... deflate! You are _not_peeing _in_me!" Was that even possible, she wondered?

"I'm not gonna pee in you, are you crazy? That's nasty!"

"Well, why are you telling me? What do you expect me to do about it?"

"I dunno, just... don't talk about water or anything, okay?"

"Why would I talk about water, I have to go too! You're the one talking about it and making me -" There was a spasm of intense, painful pressure. "Oh fuck, I have to go so bad! Please just un-knot me!" She wistfully imagined squatting down right then and there and releasing, turning the bare ground into a huge puddle. She hated urinating when other dogs or even humans were watching. It felt... dirty, almost like mating with them around. But right now she wasn't going to wait for Mikey to leave, no matter how embarrassed she felt. It hurt too much. Undignified or not, the moment his knot was out of her she was letting it out.

"I would if I could. We're in the same boat, you know!... oh man, boats go on water, sorry, I didn't mean to talk about water!"

"Stop talking about talking about water!" Lena barked.

"Okay, okay, I didn't mean to, just calm down!" said Mikey. Lena took a deep breath, and got her hyperventilation under control. "Let's just make a promise not to pee until we can separate! I don't wanna - I don't wanna get you all wet!"

Lena sighed shakily. "I promise." God, a promise sounded so romantic. This was why she loved him. He could be a dumb jerk sometimes, but he was sweet. She wished she could reach to turn around and lick his face.

But Mikey just wouldn't go soft. Soon Lena's bladder was cramping, and she was starting to doubt that she could keep her promise. But Mikey cracked first. "Lena... I don't think I can make it!" he groaned. "I'm sorry I drank so much water, and I - I'm sorry I got us stuck together! I don't know what's wrong with me!"

"Don't say that!" the collie said, alarmed. "We can do this together! Just... you're holding it right now, right?"

"Y-Yeah."

"Well, just keep doing whatever it is you're doing, and we'll... we'll make it, right?" Lena put on a fake smile. But deep down, she had come to terms with the embarrassing incident that was going to happen. Sooner or later, one of them would lose control.

As it turned out, it was sooner. Just a few minutes had passed when Mikey let out a resigned whine. "I'm sorry, Lena... I tried my best..."

Lena felt something warm inside her, then trickling out of her. Like cum, but... wetter. Her ears stood at attention and her eyes became the size of tennis balls. "Oh fuck! Mikey don't! I don't have a way to wash off, my owners will find me like this and think I -"

But Mikey didn't stop. He couldn't. The air filled with the smell of male dog urine. It would have been sexy as a scentmark on a bush, but inside her... no, not just inside her, all over her legs. The fur was getting soaked. She looked down between her paws and saw liquid running and dripping down, making a puddle in the dirt. He'd been going a _long_time too, but with no sign of stopping. Mikey let out a mournful howl.

"Never mind," Lena said, shuddering with embarrassment. "Just get it over with. Let it out..."

"Okay," Mikey said, but there was no change in the flow of liquid flooding Lena's privates. "I'm trying... I can barely pee when I'm hard, though." But he lifted his leg, and the waterfall running down the dogs' legs got stronger. "Ahh..."

She really wished he wouldn't lift his leg. Even though she knew he was having an accident, it made it feel like she was doing it on purpose, like he was marking her. Marking her as his bitch, his little overheated bitch who was so sexy that his knot just wouldn't go down, a dark little corner of her brain said. She stuffed it down. It was just the sensation of liquid flooding out of him and into her, she told herself. Her mind was tricked into thinking he was cumming. She _wished_he could cum this much, even if it got all over her legs. It would be a gross, sticky mess, but she wouldn't mind licking it off if she had to. Or letting him lick her off... or licking his cock clean... maybe tomorrow. It wouldn't get stuck in her _mouth_at least.

It seemed to take hours for Mikey's bladder to empty itself, so long he had to switch legs. They were all wet, they were standing in a puddle of his piss that wasn't even soaking into the hard-packed dirt fast enough. Lena felt humiliated, degraded. She almost forgot for a while her own urgent need. But not for long. It was impossible to not think about it for long when she was this desperate. It hurt! It hurt so much! "Mikey..." she admitted. "I don't think I can hold it much longer either. Especially standing like this. Can we try to... ow.... lie down?"

Lying down on their backs made it feel a little better, but not for long. There was just too much. She squirmed and whined and whimpered, but there was no denying the inevitable. She relaxed and lost focus just for a second, and felt herself start to leak. Like a dam bursting, there was no stopping it once it started. There was a wet hissing sound, and she felt her nether regions get drenched again, felt her tail get wet... and then she saw it. A stream of pee, going up into the air.

"Lena! Lena, you're peeing on me!" came Mikey's alarmed voice. "Stop, stop!"

"I - I can't! I'm sorry, Mikey, I'm so sorry!" Lena tried as hard as she could to stem the flow, but her exhausted bladder muscles gave way completely. A gushing, wavering yellow fountain rose high into the air, splashing down like the spray from a hose. Lena had never felt more embarrassed or guilty in her life. It hurt too much to get up. She just lay there helplessly urinating all over her boyfriend, her aching bladder ignoring his pitiful yelps of protest.

When her bladder was finally empty, poor Mikey was drenched. His belly, his chest, his paws... oh no, even his face! Her own face became wet with tears as she kept apologizing.

"It's okay," Mikey said as they shakily got up. "I've always been a water dog," he joked.

"But this isn't water!"

"Then what were we just drinking?"

"That's not what I meant! I know it's mostly water, but... well, you're soaked! You smell like pee!"

"I smell like _your_pee..." Mikey said dreamily. "It's weird, it's... it kinda feels right. Like I'm yours now. Like you marked me or something."

"What?" Lena was almost speechless.

"I know, I know, it's weird, but..."

"No, no, I... I was thinking the same thing kind of. Like... if I'm going to get peed inside, I'm glad it's your pee. But it's all over you! That's way worse than just my back legs!""

"I know... I know... but it was just an accident. And it washes off, right?"

"I guess..." Lena whimpered. One way or another she was guaranteed to get a bath when her owners got home. But the best case scenario was they'd find her covered in urine. And that was if Mikey's knot even went down by then.

Then things went bad to worse. Her stomach grumbled and gurgled again. Something was moving

inside her... and fast. There was a worrying stretched feeling from deep inside her bowels. She ignored it as long as she could, but - oh, this was getting bad! "Uhh... this might be a bad time to bring this up... but I have to poop too."

"Shit." The color drained from Mikey's face.

"I'm trying not to."

"No, I mean that's not good. Uhh... how long do you think you can hold it in?"

"I don't know. Probably still a while, but -"

"Until your owners get home?"

"What? No! I wouldn't have said anything if I could go that_long! Maybe a couple of hours?" There was a feeling inside her that was almost _wet, and the need got stronger. She groaned. "Ohh... never mind, maybe an hour."

"That's good..."

"Good? What the fuck, why's it good? You'd better be telling me your knot's gonna be down by then!"

"No..." Lena could see the concentration on her mate's face. "I just... don't think I can make it that long either."

"What?" Lena's life flashed before her eyes. "Mikey, please tell me you're joking."

"Sorry... I don't think your food agrees with me."

"Me neither." Lena pawed anxiously at the ground. An hour might have been generous. "Oh fuck, fuck, why is this happening to me? Mikey, if there's anything you can think of that'd make your knot go down -"

"You think I'd let you pee on me if there were things I hadn't tried?" Mikey's voice sounded as panicked as Lena felt. "I don't know what's wrong with my body, I'm serious! Please stop being mad at me! I didn't do this on purpose and it hurts being hard this long and at this rate my owners are gonna come home and find me missing!"

"I know, I know... I'm sorry, Mikey." Lena took a deep breath. "Let's just... hope it goes down... this time."

They stood there for what felt like eons, the pressure in Lena's bowels getting stronger and stronger. She was trying with all her might to hold it in, but sooner or later, she knew the accident was coming.

And then... "Oh, no! Fuck! Lena, I'm so sorry! I can't make it!"

Lena looked back in alarm and horror to see Mikey lift his tail. There was a horrible smell, and she felt something hot and sticky press against her butthole from the wrong side as they stood there helplessly tied together. It spread out across her rump, and she heard something wet hit the ground with a series of wet plops. She couldn't believe it. She didn't believe it for a few seconds, because she wanted so much not too. He was actually... he was actually shitting on her.

She tried to pull away, but only tugged Mikey off balance. He stumbled, and their butts mashed together right as he let out a wet fart. The mess was getting everywhere now. She felt a glob roll down her leg and cling to her heel. The poor collie started to cry from embarrassment.

When Mikey's load finally stopped, there was a pile of shit on the ground that probably would have taken multiple bags to clean up. Lena gingerly lifted a paw to try to steer them away, then set it down again. There was no point. There was even more still mounted up around their anuses. The fur on the base of her tail was all sticky.

Lena's own urge to defecate kept getting worse, until she let out a whimper not of humiliation, but of pain. Her asshole shook from the effort of trying to hold back what felt like a mountain of shit. She tensed every muscle in her buttocks and thighs. She _refused_to degrade herself any further. She wasn't going to shit herself... she wasn't going to shit herself... she wasn't going to shit herself!

"Lena? Are you okay? You repeating things makes it sound like you're going crazy." Oops, she'd been saying that out loud.

"Huh? Sorry. I'm just trying... ugh, this feels so bad..."

"Lena, it's going to be all right. Just let it out..."

"But that's... We're..."

"I know. But it can't possibly get any worse, right?"

"I guess not..."

"So don't hurt yourself trying to hold it in."

Lena let out a resigned sigh. She relaxed, just the tiniest bit, but she was on the edge. Her butthole was forced open, and an enormous log of soft feces surged out with an audible SBLURP! Oh god, that was disgusting! She could feel its weight pushing Mikey's shaft downward against the wall of her vagina. She immediately regretted her decision to give in, but it was too late to stop. More and more mushy waste oozed from her trembling behind, displacing some of Mikey's and it splattered onto the ground. Her poop was, if anything, even worse than his. It was so disgustingly sticky, to the point where it might have needed the Wet Wipes of Shame even if she squatted down like normal. "Oh, fuck... this is so gross..." she groaned. A burst of gas escaped her, hissing and sputtering, and more made the next few turds crackle noisily as they slipped out.

Then, for a moment, there was a respite. She stood there panting and sobbing. Her own sticky waste had run down all over her already piss-soaked legs. But it couldn't possibly get any worse now... right? No, it could. Much worse. Her bowels felt painfully empty and painfully full at the same time. Something almost sharp-seeming probed at her struggling sphincter from the inside. It was like the time she'd eaten a whole bar of chocolate and was getting up and running to the door all night and her owners had to pressure wash the patio. This was going to be runny.

She tried to let it out just a little bit. Slowly, to keep it from going too fast and spraying and making an even worse mess. It worked at first, just a calm river of shit, but she was battling the floodgates the whole time. Then her gut cramped, and there was nothing she could do to hold it back. A jet of liquid slop sprayed out of her with a horrible drowned SPPPTTRRRLBRLBGLRP! "Oh, no!" She whined pitifully. "Ow..." BLLLRRRRRPPPRRPRBLRP! Lumpy liquid filth squirted out of her over and over, spraying all over Mikey's butt.

"Oh, man, that doesn't sound pleasant," Mikey commented. "Are you feeling okay?"

"What - the hell - do you think?" Lena panted.

"Sorry. Oh, and extra sorry because I've gotta go again, and I think this is gonna be-" His last word was drowned out by an explosion of watery dogshit. Lena's stomach churned as she felt the torrent of sludge splash all over her ass and pour down her legs.

"Damnit! Mikey, that's horrible!" Lena barked.

"Sorry... blame your owners, they're the ones who gave us this crap."

"_Us?_That was my food, you mooch!"

"Seems like I... ugh... took a bullet for you by not letting you eat all of it."

"So? It's getting on me anyway!" Another painful cramp wracked Lena's abdomen. Without thinking about what she was doing, she bowed forward, lowering her elbows and chin almost to the ground in a Downard Dog pose to try to relieve the pain. The only problem was, her ass was facing anything but downward, and she had no control over her bodily functions anymore. The next cramp didn't hurt as much, but that didn't help her hold it in, and the stream of sewage went up into the air like her pee had. Mikey let out an anguished yelp. She looked back, and saw brown liquid dripping down his flank.

"Oh no! Sorry Mikey, I didn't mean to do that!"

Mikey nodded, grunted, and unloaded another torrent of slop. "God, it really is painful..." Then he bowed down too. Lena wanted to scream, to beg him to stop, but did she have any right to after the terrible, selfish thing she'd done? She whimpered quietly, her heart pounding with dread, as she waited for him to let go. Maybe it wouldn't be too runny this time. But the pointer's bowels exploded. A foul, thick fountain of fecal slurry blasted into the air and splattered down on her back with appalling violence.

Lena tried to get away, and Mikey bucked back and forth, but they were still stuck fast as more and more diarrhea spewed out of their asses. But it was almost like... almost like they were mating again. Actually they were, weren't they? It felt good, despite the pain, despite the disgust.

"Oh wow..." Mikey panted as he unleashed another bubbling river of muck. Some of it sprayed Lena's rump, but most of it poured down over their privates as they rhythmically thrust together and apart with disgusting wet squelches. Everything was wet... and slippery. "Oh man, this feels great. Keep going..."

"Keep going what? Humping, or pooping?"

"Either..."

So Lena kept humping, and she kept pooping. There was no way she could have stopped anyway, and the motion seemed to be loosening her bowels even further. But he was right. It did feel great. The collie sighed and accepted her filthy fate, giving in to the relief of her heat and the relief of her bowels. The two pooches took turns showering each other with stinking geysers of doggy diarrhea. Mikey's defecation was becoming more violent. Her shoulders were painted with his shit, and it was dripping down her forelegs. But Lena knew his body had to be just as soiled.

Then diarrheal disaster struck. Mikey stopped humping her, and groaned and quivered as a cramp hit him. She saw a scattered stream of shit hit the ground in front of her face, and shut her eyes just in time. Something warm, wet, and slimy battered down on top of her head. "Ugh... no!" She growled in revulsion. "Mikey, you son of a bitch! You shit all over my face!" There was no response, just a gurgle and another wave of soupy excrement pouring down on her. Her forehead was splattered, her muzzle coated, her ears soiled. The stench was nauseating. She half sobbed, half gagged, and her asshole erupted with a noisy torrent of slop.

"You got mine too!" Mikey didn't sound as disturbed as he should have been. He was humping her again. "Oh fuck! Lena keep going, I think I'm gonna... ahhh..." He shuddered in ecstacy. More gentle diarrhea ran down all over Lena's headquarters as he came. Then everything was still other than their panting breaths and the dripping of feces from their bodies. Lena stood there trembling, crying helplessly. But then...

It slipped out.

His knot had finally gone down.

She was too stunned to process what had happened at first. She slowly stood up and turned to face her lover for the first time in a while. The sight made her want to cry. Mikey was a complete mess, shit splattered all over his fur from head to tail. She'd done that. And he'd done the same to her. They were completely filthy, dirty, _bad_dogs who'd just had the worst accidents off their lives all over each other.

But Mikey was smiling. His tail was all dirty, but it was wagging. A turd slowly slid off his forehead. "Well," he said. "Better out than in, right?"

There was shit all over his dick too, and the fur around his ass was completely plastered down. Maybe the extra lubrication had helped? Or maybe...

Mikey did something unthinkable. Something disgusting. He licked his lips. "That was... really hot," he said.

"...What."

"Well, it was... it's gross, but for some reason it's like it... turns me on because of how gross it is."

"Mikey, this better be a fucking joke."

"No, I'm serious! The way we just... totally lost control like that was incredible! I haven't had a real accident like that since I was a puppy. It felt so... naughty!"

"Oh my god, you're actually serious, aren't you?"

"Yeah. I mean, don't you feel the same way a little, with how we're forbidden lovers?"

"Kind of..." Lena admitted. "Mikey, I feel that way about us mating, not about us shitting ourselves! That's just... nasty! What the hell is wrong with you?"

"I don't know!" he panted. "That's what's exciting. I think it's like... marking, but _extra_naughty because it's wrong to mark with poop even outside!"

"Ugh... well, what do you want me to do, rub your nose in it?" Lena asked sarcastically.

Mikey let out a long, high whine. His ears folded back, but a really stupid-looking grin spread across his face. "That... actually sounds kinda fun."

"Well, do it yourself! Leave me out of it! Ugh, if I knew you were _this_much of a freak I wouldn't have fucked you! Don't tell me you're one of those weirdoes who rolls in messes at the park?"

"I didn't know I was this much of a freak either," Mikey said half-apologetically. "I don't think I am. Unless it was _your_mess."

"Ugh..." Lena rolled her eyes and turned away. But then she heard a muffled groan of pleasure, and an appalling slurping sound from behind her. With growing horror, she turned around. He was actually... he was actually _eating_it? She felt like puking, but she couldn't look away from the horrific sight. He was licking up the filth on the ground with big, sloppy strokes of his tongue. "Are you kidding me?"

Mikey looked sheepish. "Sorry. I think I kind of worked up an appetite."

"I'm never letting you lick my face ever again, you know that, right?"

"What about the rest of you?" he asked innocently.

Lena's brain shorted out. How was she supposed to even respond to a question that perverted?

"Pleeaase? I know it won't get you clean, but it'll get you a _little_cleaner."

"...Fine..." Lena finally yielded. There had to be something wrong with his head, but it was almost endearing how pathetic he was. "But not between my legs. Or my face."

"Okay."

Lena closed her eyes, shuddering in revulsion as she felt her mate's wet, sloppy tongue licking the wet, sloppy shit off her body. But to her surprise, after a few licks Mikey gagged.

"Never mind..." he groaned. "It tastes... it tastes way better when it's yours."

"Really? We've been eating the same food!"

"Really! See for yourself if you don't believe me!"

"No." Lena was a little curious, but not _that_curious. Besides, it all smelled the same to her.

"Hey, Lena?" Mikey asked after a long silence.

"What?"

"Can we do it again? It'll be a long time before your owners get back, right?"

"Huh? Uhh... do what again? The mating, or the pooping on each other?" Lena was a little afraid he'd actually answer the second. Her stomach was churning and gurgling again, and she already had to go.

"Just the mating. Unless you want..."

"I_don't!_"

"Oh... sorry. I'll just..."

Lena hated herself for what she said next. It was just the heat hormones talking, it had to be! How could she be interested in sex at a time like this? "I only meant the second one!" she blurted out. "I..." She stared at the ground in embarrassment. "I don't _want_to want it, but I do," she confessed. "And besides... what difference does it make, right? I'm... I'm chained up in this yard all by myself, and you're bigger than me. You could just... have your way with me, right?" A smile tugged at her lips.

This time it was Mikey's turn to raise an eyebrow. "You're into that?"

"I've had... fantasies..." she confessed. "And I'd never _want_you to mount me while we're covered in each other's poop, so..."

"Oh." Mikey smiled. "Well, how does this sound? I'd never want to mount such a dirty, naughty dog, but you're just so hot and cute I can't help myself!"

"No, like... you're too friendly! I want you to humiliate me! Make me feel like a _bad_dog!" Lena couldn't believe the words that were coming out of her mouth, but the more she said, the more turned on she was getting.

"You mean like: Oh well, a bitch in heat's a bitch in heat?"

"Yeah, but with you actually trying to sound mean."

A few minutes later, Lena was standing there quivering, rendered completely helpless by the collar around her neck, as the larger, more powerful pointer grabbed her and mounted her, thrusting violently into her filthy hole. She was just a pampered little housepet... a pampered little housepet who was being ravished by the untamed, rough-living stray.

It was hard to convince herself. She'd met Mikey, and she'd met his owners. He was spoiled rotten But fake crying helped her get into it, and when she finally convinced Mikey to just growl and bite the scruff of her neck, she found real tears streaming down her cheeks.

She'd worked up, if not an appetite, at least a thirst. Her mouth was so dry she could hardly swallow. She begged her conqueror for a drink, then begged him to actually say _no_at first. She wondered if she'd be chugging water the entire time. No, Mikey had staying power, she had to give him that. But she was drinking so much! Her stomach felt like it was going to burst, and she was still thirsty!

"Wow, that's making me realize how thirsty I am!" Mikey exclaimed. "Can I have a turn?"

"You were just licking shit!" Lena growled, forgetting her submissive role. "At least wait til I'm done, you'll get the water all gross!"

Mikey, too, drank his fill. Lena had to poop again, and badly. The violent knotting she was getting was making it hard to hold it... so hard. "Oh, fuck... let me up!" the collie whined. "I'm gonna shit myself!"

"If you shit on me dick, you'll have to lick it clean!" Mikey growled.

"Mikey. Just. Stop trying. You sound like a pirate!"

"Sorry."

If she was honest with herself, Lena didn't really try as hard to hold it in this time. At least, until a little bit leaked out, and she realized how _naughty_it made her feel. Oh, this felt good... it felt incredible having to fight against her own bowels while he fucked her... while he _ravaged_her. "Ohh..." she moaned. "I gotta go... Mikey... Please... can you hold it in until I can't?"

"Whatever, Missy, but I hope you like the taste of your own shit!"

"Oh, you brute!" Lena's haunches quivered. But she didn't last long. Cramp after cramp hit her, and her poor asshole finally let go of its own volition. Another wave of foul diarrhea poured out of her. Mikey let out a howl of pleasure, and bit down on her neck again. Oh... this was too degrading to bear! She was soiling herself, unable to get up because she couldn't stop him having his way with her, and he was _cumming_in her while she did it!

A spasm of pleasure hit her. Her muscles clenched and unclenched. Oh, god... oh god this was... "Yip! Yip! Yeep! Yiee-iiieeeiipe!"

The border collie was wracked by a shuddering climax even as liquid shit spewed out of her and poured down her quivering legs. Mikey slid out of her, his own orgasm done, and she collapsed into the puddle of filth. The shame hit her instantly. She tucked her tail between her legs, not even caring that a little more shit leaked out of her and soiled it too.

She'd had an orgasm. While covered in shit, while being fucked by a shit-covered dog, while shitting herself. And she'd enjoyed it.

She started to cry softly. What was _wrong_with her?

"Are you okay?"

"Yeah... I'm just such a mess... oh fuck, how am I still thirsty? Goddamnit Mikey, the water's almost brown!"

"Sorry! I thought you were finished!"

Lena was disgusted. She thought she was going to vomit. But she was so,_soo_thirsty! She lapped at the fouled water bowl.

"...Fuck... it really doesn't taste that bad, does it?"

"I told you." Mikey sounded smug. "So... are you going to lick it?"

"I... I don't know..." she whimpered. "I think I need a hug."

But soon, the dogs' bladders were full to bursting again. Lena promised herself she'd hold it as long as she could. She wanted to have an accident again, and see if it felt as good the first time. But Mikey... she had an idea for what he could do. A terrible, disgusting idea. The first time, she'd gotten him way, way wetter than he'd gotten her. And she felt a little bit disappointed.

"Hey... Mikey..."

"Yeah?"

"Can you mark me?"

"Are you sure? I mean, my dick's kinda... messy, thanks to you."

"I'm sure. You ravished me, now you have to claim me. Mark me as your property. Right?" She grinned cheekily.

"Yeah... yeah, I guess I do." He stood up laboriously. "Where do you want it?"

Just on her lower half, she thought. Maybe he'd let her wet her chest a little, if she was feeling up to it. "Everywhere," she answered without thinking.

"Uh... if you say so. I think I have enough in me for that."

Oh god, no! What had she gotten herself into? He was going to... he was going to piss on her! Wait, was she really sure about this? It was too late, he was lifting his leg...

This time, she could _see_the robust, shining stream start to flow from his shit-smeared member. And she was enjoying the view. But not as much as she enjoyed the sensation of the warm, musky liquid soaking through her fur. Pale golden rivers poured down her flank as Mikey sighed in relief. It was like a faucet... like a garden hose! She rolled onto her back, wagging her tail, and let him drench her belly. Experimentally she brushed his cock with a hindpaw.

"Oh, that feels nice..." Mikey said. He pissed all over her paw as well, then moved higher. Her chest was the target of the golden river now. The stream was so close she could lean forward and taste it... _why_was she thinking of doing so with anything but revulsion?

"Everywhere?" Mikey asked.

Lena gulped. "Everywhere."

Oh, god... it was so warm... she was so soggy... it smelled so much like him, she smelled so much like him now. Her paw strayed to her neither regions, and she started to rub as a torrent of pee cascaded down on her head. It felt so good, especially when she was desperate too. But she wouldn't let go... not yet...

As Mikey's stream petered out, Lena made a decision on impulse. She opened her mouth. Oh god, it was salty, just a little bit salty! It was so good! She tenderly licked the last drops from the tip of his red rocket, and then just kept on licking, and kept on rubbing herself. She gagged at the foul taste of her own excrement, but she couldn't stop.

Mikey got hard again almost immediately, filling her maw with his length. Lena's paw started to get tired, but the pointer turned around, rolled her onto her back, and sniffed at her crotch. Then he started to lick, too. Lena was horrified. His dick was bad, but her nether regions were far worse, sticky feces plastered into her fur. He was making the grossest wet, sloppy squelching noises with his tongue, but it felt too good for her to ask him to stop.

"Uhh... Lena?" He asked. Lick, slop, glorp.

"Hmm?" Lena mumbled through a mouthful of doggie dick.

"Do you have to pee again yet?"

"Are you joking? I've been bursting for ages!"

"Can you pee now? I want to get the poop taste out of my mouth a little."

"I guess..." Lena said reluctantly. "I was saving it, but..." anything for him. And her heart was fluttering with excitement at the prospect. He was going to actually drink her pee? Right from the tap?

She redoubled her efforts, servicing his foul-tasting member extra-vigorously. It felt like his muzzle was lost in the liquid depths of her poopy puppy pussy. But somehow, this was heaven. The collie gave in to her aching bladder.

"Oh-glgblgglbglll!" Mikey gurgled. "There's so much - Lena, I'm gonna..."

Lena reduced her flow to little squirts. Mikey shuddered, and something hot and thick and sticky filled her throat. "Thagltltats.... glck slrrrp... my line!"

"Not that!" came Mikey's panicked voice. He arched his back, and his cock slid out of Lena's mouth. Thick ropes of cum splattered her face. He shuffled forward. "Oh no... Lena, I'm sorry!"

Still spurting his love onto her chest, the pointer squatted. Lena stared up at the slimy, shit-smeared horror between his legs. Almost lost among the caked-on filth was a shivering, clenching pucker. "Oh no!" she screamed. "Mikey, no! Somewhere else, somewhere - UGGGGLBBGLBGLBL!"

The border collie's boyfriend's bubbling bowels blew up in her face with apocalyptic force. There was no subtlety, just an explosion of filth. She closed her mouth as soon as she could, but in that instant it was filled to the brim with hot sludge. BLLRRRRRRRTTTTTTT! His asshole trumpeted with diarrheal dismay, spraying Lena's whole face with flecks of crap. He groaned in pain. She spat as much of both his loads out as she could, but a soft log slithered out of his rear and splatted down on her forehead, covering one eye. It was only a brief reprieve before he erupted with another mudslide of volcanic slurry.

It was pouring down on her... all over her... it was in her mouth, in her nose. She couldn't breathe! She sneezed violently, the force of it slamming her nose right into his rump. She gasped for air, and yet another crackling river of muck overflowed her mouth again.

A trembling Mikey finally stepped off of her, apologizing profusely.

"God... damn you Mikey!" she spluttered, spitting out as much of the feces as she could. But she just couldn't get the taste out of her mouth. "Did you _have_to do that right there?"

"The cramps were so sudden!" Mikey said. "Maybe that wasn't a good position after all..."

"What am I, just a toilet to you?" Lena complained. "You idiot... Oh my god it tastes like sh... never mind."

But... it was actually kind of hot, if she thought about it the right way. She hadn't just been marked, she'd been used as a toilet against her will. Her owners probably wouldn't even _touch_her, she was so disgusting and filthy! They'd have to hose her down from the other side of the yard! And her bladder was still full almost to bursting. She could still have her accident. To her astonishment, she found her tail starting to wag. She raised it in the air and bowed playfully, wagging her shit-caked rump. "Never mind. Do you still want some of this, Mikey?"

"Ohh... yeah, yeah I do."

"Okay, but you'll have to wait. First... I take back what I said about licking my face."

Mikey squirmed a bit, but did his duty, bathing her with his sloppy tongue and not really making her any cleaner. They rolled in the mess all over the ground, and soon were almost totally covered in their own waste. Lena's stomach grumbled again, and her bladder twinged. She couldn't put it off much longer. She raised her ass in the air and presented herself again, now doing a potty dance.

But after a few thrusts, Mikey got down off her with an alarmed expression. "Uh oh... I'm about to have another accident!" he groaned.

"Really? Well, I've worked up a bit of an _appetite_too!"

But if her face was between the pointer's legs, his doghood couldn't be between hers. She couldn't enjoy both at once. Unless... the food bowl was still empty.

Mikey's latest bowel movement was a little more solid, but still soft, with creamy logs of shit mixed with shapeless mush. It burst and sputtered from underneath his wagging tail, a huge pile spreading out more and more... and more... until the bowl was full with a gigantic sloppy mound.

How was that possible? He hadn't even eaten that much! But Lena didn't feel like asking questions anymore. She was a total slave to her vile urges. She gave her mate's anus a couple licks, then buried her muzzle in the repulsive sludge and greedily began to lap it up while he went to town on her other end.

But it was too much. Her stomach couldn't take it. She burped, and bile rose in her throat. As Mikey came, a wave of nausea rolled over her. "Oh, fuck... ugh, I'm gonna puke..."

Mikey lay there, oblivious in the afterglow of his climax. Selfish prick. Lena gagged again, and a horrible idea struck her. This was all his fault. All of it. She'd make him pay. She straddled him, coming down on his still half-hard sausage right as her stomach decided to expel its revolting contents. A tidal wave of twice-eaten, half-digested kibble shot up her throat and poured from her drooling maw, drenching Mikey in a waterfall of fecal vomit. She hurled over and over and over, overpowering both her mate and her protesting bladder with strength she didn't know she had in her. He was vomiting too, a river of puke bubbling up and making a puddle around his head, but it meant opening his mouth.

That took them both a while to recover from, alternately panting and crying and running to the water bowl and chugging vast quantities of fluid to try to clean out the nasty acid taste.

"Gah... this isn't working!" Lena gasped. "Mikey, do _anything_in my mouth. I don't care what as long as it isn't more puke!"

"Okay! But you have to do mine!" Mikey agreed. "Wow, I can't believe I'm full again already! We really drank a lot, huh?"

"Shut up and pee!" Lena gagged a little, still drooling, but opened wide as he stood over her and lifted his leg. "Hurry up! What the hell, I thought you said you were f-mmmph!" She was silenced by a fresh flood of pee. She gratefully let it flood her mouth and run down to the back of her throat, gargling and blowing bubbles. So warm... so... so clean by now, they were both so well hydrated. But it still had that faint saltiness, and that faint taste of Mikey's wonderful, wonderful scent. She took him into her mouth and gulped down generous, hearty swallows. "Mmm... so good!" She lowered her head. Mikey, still urinating like he was trying to mark a whole city block, showered her face. Waterfalls of piss poured off her muzzle onto his forepaws. She lovingly nuzzled his length. "Oh... yeah... keep soaking me!"

She was disapointed when his stream finally ceased, and she didn't stop licking. "Hey, Mikey?" she asked. "Do you mind waiting a little longer? I'm still thirsty for you."

Mikey didn't answer, but he certainly didn't stop her slurping and sucking and nibbling until an outburst of sticky, white liquid splattered her face.

"Yeah... I guess I didn't mind..." he panted.

Lena's bladder cramped, and her bowels gurgled a final warning. She'd felt the signs building up inside her for a long time. She'd ignored them a little too long. She tried to stand up, but the slightest movement made a short jet of urine escape her. She felt the heat running down her clenched legs. "Oh no! Shit, shit, shit! Mikey, roll over quick, I'm gonna have an accident!"

Even in the few seconds it took her, there was already more urine dribbling out of Lena. She was almost beside herself with joy even as a stabbing pain assaulted her nethers. She'd never had to go like this in her life! She hurriedly squatted over his face and released herself. The gushing flood was almost deafening! "Oh... oh, yes..." she sighed. Mikey gurgled helplessly under the fire hose like cataract bursting from her nether regions. A puddle reached her back feet. She looked down between her legs, and almost creamed herself at the sight of her sodden mate. She was so desperate she couldn't hold still, and her stream was going everywhere, but there was still enough to fill his mouth to overflowing and saturate his fur. "Mmm..." she giggled innocently, completely submitting herself to the joy of relieving herself onto another creature. Still peeing, she lowered herself to his mouth, and felt his tongue caress her folds. She was almost worried she'd drown him.

"Eek... Mikey, don't, that tickles. I have to poop too, don't make me..." Never mind, that was probably what he wanted. A sly grin spread across Lena's face. She pushed, and runny poop splattered all over his chest. Just a little. She didn't let all of the enormous load she felt brewing out. She had a plan for it.

"I think I still have to poop some more," Mikey mumbled. "Oh... yep, definitely have to poop. This is gonna be bad... Our mouths are all clean now, what should I do?"

"Just a second..." An explosive pressure wracked Lena's own guts. "I wanna test something."

"What?"

"I wanna see for myself if you're right... that it tastes better when it's not your own... or if I just taste better than you." She lay down and laboriously craned her neck to reach her own crotch, and almost lost control right then and there. She was so desperate! Licking... licking... she could reach with her tongue, even when she was bloated like this. Yes! BBBBLBLBLBLRRRRRPPPHHHFFTTT!

A seething slurry of squishy scat erupted into her waiting mouth. Oh... yuck... oh, yuck... oh, yes!

"Well?" Mikey looked on, doing a potty dance.

"I don't know..." Lena licked her own filth from her lips. She let out a long, airy fart. "They seem about the same. I think I need another comparison."

She'd always been a flexible pup, and by rolling on her side a bit, she was able to stretch until she could actually see an incredible, exciting sight. Her own butthole, underneath a fluffy, wagging tail completely coated and smeared with feces. It was surreal, seeing her own sphincter actually bulge outward as another boiling cramp hit her. A few drops of brown fluid leaked out. Her heart raced. This was going to be so yucky!

"Are you ready?" she looked up at her mate, doe-eyed.

"I'm trying to hold it in here..." Mikey grunted.

"Okay, then just let it out!" Lena said, and did the same. At first, a surprising amount of piss soaked her muzzle. Her bladder must have still had some liquid in it, that was forced out by the position. Then something awful, something runny, started to leak out of her bottom.

But when she finally let go, it was explosive and completely uncontrollable. With a sputtering roar, a dung tsunami of unbelievable proportions exploded from her tailhole. There was no way to hold back the tide from her upset tummy, just open her mouth and let it flow. She felt chunky blasts of slurry shower her body from somewhere above her, but she was focused on her own excretions. The poor pup defecated torrentially into her own mouth, filling it to the brim with scat, but there was no hope of containing this mess. Even if she'd swallowed, she knew she'd never be fast enough. She just held it there and kept pooping like some incontinent slut-puppy.

"Unh... hang on, Mikey... she finally managed to clench down and stop the flow, but she know she wouldn't last. "Can you bring the doghouse over? So I can reach with my leash? And hold it there for a minute?"

Mikey didn't understand at first, but he obeyed, and Lena used it as a wall to push herself up against and turn upside down. Before, when Mikey had stood over her with his face in her crotch... when she'd been directly under his rump as he defecated... that had been incredible. But the pinnacle of degradation would be to simultaneously shit herself and be shit on by herself. Yes... this was perfect... she was directly under her own ass, curled up like this. Close enough to lick... that felt good. Her vulva was dripping creamy fluid onto her belly. She was so dirty... so nasty...

"I've got a little bit more in me," Mikey panted. "Where do you want it?"

"Everywhere!" Lena said. The storm in her gut was brewing fast. Her own spread legs, her own wagging tail, her own anus loomed tantalizingly over her. "Oh Jesus, Mikey, I thought you said a little!"

It was a great dane's dump worth of shit, and that was no exaggeration. But it really was a little compared to what Lena's bowels served up. Thick, creamy, heavy turds slid down her crotch and belly. She leaned forward, and let another log drape itself over her face, and even more slither into her mouth, but the load suddenly turned runny again. But she didn't care. She was a bad dog, a naughty dog. She deserved this horrific fate. Blorting and splurting, she soiled herself in the sexiest way she could imagine, worshipping her own cute little asshole as it produced a chocolate waterfall of diarrheal soup.

She didn't even care if her owners found her like this anymore. She wouldn't have cared if they came into the backyard right _now._It was all worth it. They'd just have to accept that dogs weren't clean animals.
