“You gonna do it or not?” Maurice asked. The gorilla was sitting on the toilet with his pants and underwear wrapped around his ankles. In one hand he was holding his phone and the other was slowly stroking his fat semi-hard cock. He had taken a piss in Rumble’s bathroom the other day and saw that there was a large litter box in the corner, being much too big for any housecat. And the cougar didn’t even own a cat. So when he returned to the living room, Maurice asked what it was about and the blue feline grew flustered but still explained that it was his. That he used it from time to time. That it was a kink thing. He expected the gorilla to be off put by this reveal but Maurice actually looked interested. More questions were asked and Rumble answered with more confidence, realizing that the primate was interested on some level. It had been less than a week since then. The next time Maurice came over things were like usual until he announced that he needed to go to the bathroom and was adamant on Rumble coming along… Now the cougar was completely nude and kneeling in the litter box. He was feeling a bit shy, not because of Maurice being there but because of the phone that was primed to record what he was about to do. ”This will just stay between you and me,” Maurice said. “Now hurry up.” Rumble grunted and then sighed, his cock twitching and letting loose a thick stream of urine that was splattering down into the dry grains. His stream grew stronger as he relaxed instantly, focusing on the pleasure of draining his bladder. He was kneeling in the litter box and could feel the warmth spreading outwards as more of his urine was being absorbed. He was surprised by how much there was in his bladder, seeing the increasing amount of darker and damper litter in real time and watching it clump up. The litter was fresh and yet the scent of his mark was rising from the box, reaching his keen nose and making him excited. As he finished, Rumble looked up at the gorilla with a sheepish smile. “Good boy…”Maurice said, using the hand that had been stroking himself with. It was extra warm and a little damp too. Striking the feline’s nose was the smell of his musk. It was always strong coming from him; perspiration from walking around in the city heat with hints of even older sweat being left on his body. There was just something about it that the blue pantherine couldn’t get enough of. “Is that all?” Maurice asked, still holding his phone to Rumble, keeping him perfectly in view of the recording. As if by some kind of force, Rumble suddenly felt something drop in the pit of his stomach and the need to poop struck him hard. He grunted and nodded. ”Why don’t you turn around and hike that tail up a bit so we can see,” Maurice said. Rumble nodded again and did just that, shuffling around in the large box, getting litter stuck to the fur of his legs and knees until he was facing the opposite direction. Then he leaned forwards and lifted his tail, letting his winking and expanding rim be seen. Unable to hold it back for even a second longer, Rumble groaned and just pushed. His hole expanded fully and the start of his waste could be seen. Then it came sliding out, a hefty but semi-soft log that was a mid-brown color, slinking out with ease. First it was sticking out from the cougar’s rear. Its own weight caused the end to break off and thump onto the sandy layer that Rumble was kneeling over. “Yeah, that's it…” Maurice muttered. He was palming his cock with more passion as he watched the big and muscular cat shitting. Seeing him hunched over, hearing his grunts and seeing the way his tail slightly bent as more came out of him. Rumble was in good shape and had a good diet, meaning that his dumps were plentiful as well. The first long was completely expelled, being seen in the form of various chunks that had piled on top of each other. A sigh of relief came as the rest was expelled; much smaller chunks that slipped out one after the other. With that, he was finished. Acting on habit, he reached back and covered the dung with the grains, soon having it out of sight and diminishing the smell. His winking anus was still being filmed and Maurice was very pleased with what he got in his phone. He hadn’t ever given a thought to stuff like scat. Piss was something he had done often, either just pissing in places or on others. But seeing Rumble using the litter box did a lot to open him up to the idea of trying out scat stuff for himself. ”Alright, turn around and lean forwards. I’ve got something for you to take care of,” Maurice said. The litter box had been moved to be placed right in front of the toilet so Maurice could comfortably sit and record. He had planned to just jerk himself off to the sight and the recording but seeing Rumble relieving himself seemed to have an effect on him. Rumble turned around again and leaned forward. Maurice guided his fat cocktip past the feline’s lips and just as Rumble was about to start sucking, there was a rush of hot fluid, splashing all over the roof of his mouth and coming down to fill up the rest of his mouth. By how hot it was and the salty flavor…there was no doubting what it was. The scent of waste was still lingering in the air but it was quickly overpowered by the smell of gorilla pee. Rumble shook off his surprise and began to drink but by then it was dribbling down his chin and from the corners of his mouth. Even as he was gulping, Maurice was pissing freely, thick and powerful gushes easily taking up a lot of space in his muzzle all at once. The urine he failed to swallow was dribbling down into the kitty litter, at least sparing the cougar of needing to clean it up. That was a good thing as it was getting harder and harder for Rumble to keep up with the flow. He was swallowing as often as he could but was clearly struggling to keep up with the seemingly never-ending amount of piss. He groaned against the shaft, not noticing the big hand coming down, not until it was already pressing on the back of his head, pushing it forwards. While still releasing its hot and strong tasting fluids, Maurice’s cock was sliding further into Rumble’s mouth but it didn’t stop there. It kept going until the whole thing was past his lips. The tip and many inches were in his throat now, being bathed in the primate’s liquid waste. At the same time, Rumble couldn’t help but breathe in the raw earthy funk that was radiating from the ape’s sweaty crotch. It was all flowing directly into his throat. Rumble hardly had to swallow because of how forcefully it was spraying out. It was making his windpipe bulge, a surge of heat traveling downwards and spreading out to the rest of him. He could only wonder just how much Maurice had to give, how much longer would be gulping down hot and musky piss? Not that he wasn’t enjoying himself. The constant warmth was actually rather soothing, enough to make him start purring. Rumble swallowed a few more times and was glad to have finally consumed the last of the ape’s musky piss. The shaft was pulled from his throat but wasn’t pulled from his mouth completely, sitting on the feline’s textured tongue. “Now start sucking on it,” Maurice said. He maneuvered the phone to capture what would be coming. Rumble nodded and took it upon himself to push forwards. His throat was already stretched so it was no trouble to take the gorilla’s cock down into his throat again. But this time he withdrew, sliding back until he reached the tip but leaving that inside. Still kneeling in the warm litter, the muscular feline started to deep throat the large uncut shaft, moaning from the taste of sweat that was pairing well with the lasting flavor of piss. His nose was treated to more musk. That led him to pushing his head down further, taking the entire thing past his lips. While Rumble was working, Maurice was groaning. He did well to keep his recording steady against the smooth sailing of the tongue and oral walls against his cock. Moving back and forth, the feline was moving back and forth, taking all of his inches down into his throat again. It was nice and tight but what really got Maurice going was when Rumble began to purr. Those vibrations in combination with the moving throat was really doing it for him. He could feel his balls churning. But they weren’t the only thing churning. While he was getting his cock sucked, Maurice could feel his stomach roiling. He grunted, feeling his insides working to push out his own waste. Seeing Rumble defecate earlier had triggered something within him. Things had gotten moving and he saw no reason to hold it back. His rim expanded and the start of his log was easing out. His anal muscles pushed it further along, causing it to snake out and touch down into the bowl’s water. Just like Rumble, Maurice was a big guy. His physique being a mix of chubbiness and muscle, his diet was varied and he ate in greater quantities than Rumble. As a result his log was thicker and it was coming out longer than the feline’s hand. It had yet to actually break off, instead curling and coiling as it came sliding further out from the ape’s hole. The slimy coating of mucus allowed it to come out smooth and easy. While he was feeling the smooth and warm mouth caressing his cock, Maurice was also feeling the pleasure and relief from the hearty log slinking out of him, rubbing against his walls and pressing on his prostate somewhat on its way out. The first snake of shit had reached its end, audibly thumping into the bowl but that wasn’t the end of it. Maurice’s tailhole expanded again and coming out with greater ease than before was another large brown snake, piling up on top of the first and coiling right over it. The combined smells of musk, piss, and waste rising from the gaps were all filling the bathroom air, striking Rumble harder as his head was right in between the shitting ape’s legs. The usual scents that he was used to was offset by the more pungent reek of fresh waste. ”Ugh! Fuck!!” Maurice cursed, feeling the throbs of his cock getting stronger. Feeling his thick shit passing through his bowels while also being treated to a blowjob at the same time was doing a lot to get him further and further along. Rumble was sinking his head down as far as he could every time now, treating the shaft to the extra warmth and tightness of his windpipe. Precum was leaking in heavy amounts and he found it easier to manage, purring still as he gulped down the thicker and flavorful substance. The moans coming from Maurice were responded to by him purring even more while licking and sucking on the dark flesh with a greater amount of passion. For some reason, giving the gorilla a blowjob while hearing him grunt and push out more shit was turning him heavily. His cock was throbbing so hard it nearly hurt and he couldn’t resist the need to grip and pump at his shaft. Following the bigger shits were smaller but no less substantial lumps that were popping free from his rim, plopping down into the pile that had formed. Maurice groaned deeply as they left his bowels. The added pressure on his prostate and Rumble moving his head even faster was just too much for him. Unable to hold back any longer, Maurice managed to thrust a single time while still sitting on the toilet, shoving all of his cock back down into the feline’s snug throat. Against the wet walls, the gorilla’s shaft swelled and then it throbbed. Rumble readied himself but was still surprised by the powerful gush of hot cum that was firing directly into stomach. Coming out in the form of strong, steady spurts, the ape was bathing the cougar’s insides with his musky seed, leaving the walls of Rumble’s esophagus slimy from the clinging layers of spunk that were left behind. While cumming, Maurice’s stomach gurgled and another thick turd shot out of him, landing into the toilet and on top of the rest of his excrement with a wet splat and thump. Rumble was swallowing the seed as best he could but some of it was leaking from his mouth like the piss had earlier, further marking his muzzle and making the scent of gorilla musk cling to his fur. The seed that was dripping down his chin fell into the litter as well, being absorbed by the grains like everything else. Now spent, Maurice sighed deeply and pulled his still hard cock free from the panting feline’s mouth. Even after all of that, Maurice still had more left inside of him but the toilet was already at its limit. It was much smaller than the one he had back home and wasn’t rugged to handle what he could dish out either. Luckily for him there was a large box sitting right in front of him. The recording was ended and his phone was placed on the sink, the matter of expelling the remaining waste from his system was a bigger priority. Rumble moved out of the way for him but kept himself close, his tail flicking with excitement as he watched the large ape get into position. Maurice didn’t get into the box itself, walking around and standing in front of the box but when he squatted his large ass was hovering directly over the grains. He picked up where he left off, grunting as another short but wide turd was making his hole stretch. It was solid but had an extra gooey coating that left Maurice’s hole wet and a bit muddy. The gorilla wasn’t concerned about that, his focus being on the passing of his shit; pushing and sighing as more left him, large but exceptionally viscous globs that fell heavily into the litter box. ”Enjoying the view, kitty?” Maurice asked as he grunted and released a spurt of mushier filth, feeling more relief from the hardest part being over. From there he just his body do its thing, smoothly pushing out the last of his digested meals, making another shit pile that wasn’t as big nor as dense as the one in the toilet but no less funky or arousing for Rumble. “Like watching me take a big shit?” ”Y-yeah,” Rumble admitted, feeling the rise of his blush and the throb of his cock. ”Like the smell of it?” the ape asked further. He got a nod in response and smirked deviously. “How about a taste?” Rumble blushed even more and looked away, making Maurice gasp and laugh. “No fucking way. Rumble, I never thought you were into this kind of shit in the first place but…really? Damn you’re a dirty little kitty,” Maurice said. “I got just a bit more in the tank. How about you show me how much a shit-lover you really are?” ”O-okay,” Rumble said. They both moved some, Maurice shuffling to the side away from the pile and Rumble partially in the box again. He was lying in it on his back, facing upwards and the lower half of his body was hanging out of the litter box. Maurice was still outside and when he got back into his squatting position he found his ass comfortably sitting on Rumble’s face. It slid out of the gorilla without warning and before Rumble was fully ready. All of a sudden, soft shit was being pushed out and it was flowing over his closed muzzle, sliding over his lips and trailing in various directions. The sides of his muzzle, under, and along the bridge of his nose as well. All of it was being directly coated in ape shit. It came out with so much heat and it was sticky, almost like tar. The smell was overwhelming, hitting his nose directly but instead of feeling disgusted the cougar couldn’t help but purr again. He opened his mouth and managed to catch the few solid chunks that came in with the deluge of sludgey waste. With no shame or hesitation, Rumble swallowed it down in the same way he had with the piss and cum that came from the same male. Of course he knew it was filthy, that it was gross, and on some level it was also dangerous. But in knowing that it was wrong, Rumble couldn’t help but love it. He was again welcoming hot and wet fluids into his throat as he swallowed, not being fazed by the bitter waste that honestly wasn’t that bad compared to some of the protein powders he had to swallow down. While doing this, Rumble groaned and shook, breathing the squatting gorilla. His cock was twitching hard. He humped at the air and shook even harder as ropes of seed began flying from his cock. While swallowing down the last of Maurice’s fresh waste, the feline was experiencing a powerful hands-free climax. It splattered all over his stomach, covering his fur and sticking to it just as much as the shit was. Maurice was all that he could register, his musk only made all the more intense thanks to the lingering and potent haze of his shit-smell. Now that the last of the scat was expelled, Rumble went ahead and ran his tongue along the rim, sparing the ape any need for toilet paper. Surprised by this, Maurice jumped but relaxed and sighed from the tongue’s sweeps. Its texture was the perfect thing for cleaning the brown from his tailhole, leaving him feeling cleaner than if he would have used the toilet paper. ”Fuck man… We gotta do this more often…” Maurice said as he stood up, pulling up his underwear and shorts. “I think I’m gonna take off. Hehe. Have fun cleaning up the mess.” Not only was there a lot more shit in the litterbox than usual but the toilet was full of ape shit that wasn’t going to be flushed down no matter how many times Rumble attempted to flush it. How he would fix that problem, Maurice didn’t really care as he got what he wanted and more. But he knew that the toilet would be free of the waste the next time he came over.
