Daddy's thick turd

"Let's get in the bath-tub first," the tiger dad said. Him and his cub both were covered in his son's waste and getting a bit clean before continuing their perverted adventure seemed like a good idea. It would also make further cleaning up way easier as his ideas of what they were to do would soil the bathroom floor immensely.
He turned on the faucet and added a healthy dose of pine-scented bubble-bath to the splashing water, a loud fart coming out of his ass as he was bending down. The tiger cub wasted no time in scamping over, taking a deep breath and plunging his face into his father's backside, electing a gasp of surprise as the cold nose pressed against his sphincter.
The kit inhaled the musky and dirty scent of his dad's unwashed asshole combined with the residual gnarly flavour of the fart, and murred in pleasant surprise as another strong blast of nuts-and-manure smelling gas was pushed directly into his lungs. His raspy tongue began to lap at the unwashed anus, no bits of poo for him to ingest, but a thick and palpable layer of strong and musky sweat. Licking from the taint to the base of his father's tail, he savored the delicious and fragrant taste of pure unwashed adult male. Even though his tongue was still brown from his own scat they had shared a moment before, the sheer musky taste of his dirty father was overpowering enough to tickle his nose and turn his tastebuds into centers of erotic pleasure. A kind of shiver went from his tongue and nose all the way to his cocklet making it stand proudly to attention again, despite having just orgasmed.
Daddy tiger was enjoying the moment, his kit's tongue hitting all the places he had scratched at himself during these last days of being unwashed, keeping his body unclean to please his son's perverted tastes. But the pressure from within was getting stronger also, and his asshole was beginning to wink at his son, who took the cue to stick his tongue directly in. Immediately it made contact with a thick log, a mellow taste coating the tip of his tastebuds and he started lapping at it like a cat from bowl of water, each intrusion scraping off a tiny bit of delicious poop and bringing it into his mouth. This was the real treat of the evening, the kitten's own waste merely a starter compared to the main course he had been fantasizing about.
Meanwhile the water had gotten high enough that the father turned off the faucet he had been bent towards while his son serviced his asshole. A pleasant aroma of pine needles fought, and lost, to disperse the smell of shit from the air, merely masking it by a tiny fraction. The older male stood up, face scrounging up as he fought to not defecate there and now. The kit's face scrounged up too, from dissapointment, and he was pouting as his dad turned his body around to face him.
"Don't look like that, you'll get your treat soon enough. Now get in the tub before I poop all over the floor!" The kitten responded by sticking out his muddied tongue in an act of playful defiance.
But daddy would have none of that, and forcibly picked him up, kissing him deeply and tasting his own scat in his son's mouth before stepping into the bathtub, one of those anti-traction matts in the bottom probably saving them both from falling over. Breaking the deep kiss after stepping in, he slowly lowered them both into the tub, warm water enveloping the kit as a brown string of slime elongated and snapped off from between their mouths. The tub was fairly big, so the older tiger was able to sit comfortable on his knees with the water going halfway up his loins. The kit was suspended in the water, his arms pressing backwards barely keeping his head above the water as his legs streched towards his dad.
"Scoot back, kid, lean against the back end," the father commanded, with a hint of desperation in his tone. The kitten could sense the urgency and quickly scooted back, the flooring there a bit higher elevated so he could sit on his butt and have most of his upper body free of water. His fast movements caused the bubbles on the surface on the water to multiply and he looked like the monster from Bubblegum Lagoon when he was finally in position and leaning his body against the gently curved edge of the tub. Daddy tiger almost chortled at the sight, before a serious stomach cramp made him crouch forward, the very tip of the turd he was holding in pushing itself out. In a series of fast movements he brought himself to his feet and stepped and turned and squatted down, bringing his ass and that delicious looking piece of scat towards his son's face. The kitten opened his mouth, and Daddy's strong legs meant his butt ended up perfectly on his son's upturned face, brown matter pressing itself just inside his mouth. 
With a grunt like only an adult male can make, he began pushing, the fat turd slowly but with unstoppable force exiting his body. The kitten murred at first before whining in panic as the thick log was pushed deep into his mouth and started entering the back of his throat. Daddy tiger could sense his cub's distress and began to lift himself upwards as that one piece of stool was so massive he could feel the resistance into his body and lift it accordingly. He went from almost squatting to halfway standing up, before the pleasure of release told him that the stool had left his body.
As he turned around, the sight of his son using both hands to support the massive log was one of the most erotic moments of his life. Fully half again as thick as his own dick, and almost twice its length, the size was monstrous. Seeing that huge turd lodged into the throat of his kit, the cub's beautiful green eyes slightly teary from fighting the gag reflex, it was all too much for the perverted father and he sank to his knees weakly as all the blood in his body seemed to travel to his cock, making it even harder than the minutes before when they had been playing on the bathroom floor.
Daddy tiger sank to his knees in front of the boy and with his right hand took hold of the turd between where his son was holding it. The surface was almost completely dry. He has been avoiding going for six solid days to give his son a big treat, eating less and less as the days went by due to the mounting pressure in his gut. The results were plain to see and feel, the warmth and smell vastly different from almost every piece of scat he had ever played with. Earth-mixed-with-nuts-mixed-with-leaves-mixed-with-sweet-honey scents played on his nostrils. 
The kitten could barely breathe and his father's firm hand keeping the massive shit in place brought him to utter keening sounds of mounting panic while his small paws let go of it and instead started pusing on the older tiger's arm. Daddy lifted the turd upwards without a moment's hesitation and held it so it just barely was resting on the boy's lips, hardly a smudge of brown could be seen there as it was still too dry and firm to give off much material, but the taste that lingered in his mouth was so distinct and so delicous that his mewls of discontent became murrs of pleasurable naughtiness. His small cocklet, having turned flaccid in the panic, jumped to attention in three powerfull spasms, a bead of pre forming at its tip. He started suckling the turd like an infant on his mother's breasts, purring as daddy kept it there.
Naughty thoughts were jumpskating around the older male's mind and he started using the turd as an improvised dildo to mouthfuck his kit. Slowly pushing it back in, further than it was before and pulling it out to the tips of those beautiful lips before pushing in again. Slowly. Gently. Every-so-slowly pushing it further and further down until he could see the bulge in his kitten's throat from the massive stool being used to stretch it out.
The kitten was alternating between murring, gurgling and sputtering as his gag reflex was being pushed and strained to its very limits. His right hand kept fondling his boy bits and his left was grasping his daddy's, letting him know by how hard he squeezed and pushed back just how  close he was too the edge of letting go. The length of the massive log that was pushed in and out slowly started to get slimy and deposit traces of goo and colour all over the kitten's mouth, the drool sputtering out between his lips turning dark brown and coughs sprayed droplets of it all over himself, the bubbly water and even spraying his daddy's dick in one of the stronger heaves.
The father was feeling like he was transcending the mortal world, his mind bristling with static from this incredible new and naughty experience, his primal urges were taking over and he let the turd press ever faster as further into the throat of the fruit of his loins.
The kitten could barely breathe now as his throat was mercilessly fucked by that huge piece of stool, the tip of it beginning to deterioate and deposit thick mush all over his tongue and throat, his uvula going in overdrive and with loud coughs and heaves he puked up most of his own waste he had consumed just prior to this experience.
Though glazed eyes, the older tiger watched as his kitten started puking from the ordeal, tears running down the young boy's face as brown, nasty scat was being expelled from his stomach and ran between the fat turd in his mouth in big spurts down his body, some of it even being forced out his nostrils. 20 minutes of digestion were not nearly enough to break the mess down and the smell was immense, moreso for the cub whose entire mouth, face and nose was awash with the stink of it. Despite all this, he kept rubbing his tiny dick, the domination and the naughtiness and the pressure and the lack of air and the convulsions in his stomach somehow still transforming into extreme sexual pleasure.
This was simply too much for the primal overdrive the older tiger was experiencing. He had been playing with his junk the whole time, his hyper-erect dick almost hurting from stiffness, and now he decided to take it to the next level. As he pressed the fat turd down the gullet of his kit yet again, he leaned forwards and took the other end of it into his mouth, deepthroating it all the way until his lips met his son's. The vomited-up scat was immideately assaulting his senses, and his dick twitched yet again. Still connected mouth to mouth, he scooped up some of the runny scat that had covered his son's belly-fur and rubbed it all over his dick, turning it nice and slimy. 
With powerful hands he picked the kitten, still kneeling, and pressed him close to his chest, bending his head down and keeping the deep-throat scat kiss intact, the kitten instinctively understanding and wrapping his legs around his daddy's body and his arms around his neck
The kitten used his hands to guide his father's turgid dick towards his asshole, and with hardly a breath left began to sink down on it, the feline spines slowly tickling his insides as he sank down. Their kiss ended as the kitten moved down and the tiger dad kept suckling on his own thick log so the kitten could have a breath. But it wasn't breath but a sudden, scat-spitting gasp that came from his mouth before taking a big gulp of breath around the turd still lodged in his mouth as the slight pain and stretching pleasure of his daddy's cock filling his bum made him murr and cough at the same time. 
Daddy took a firm hold of the kitten's asscheeks, stretching him wide, and started to fuck him gently, his hips moving in unison with his hands for a cyclical motion that moved his kitty-maker from the tip to the hilt into his boy's well--trained bottom.
Said kit had a naughty idea and on the upswing munched his lips down, forcing the thick turd deeper into his father mouth than he had anticipated. Catched by surprise, he sputtered and his dick quivered as he suddenly came close to vomiting. Now it was the adult who got tears in his eyes and the kitten kept his lips close so each cyclical motion of their fucking pushed the fat shit deep down his daddy's throat.
Having been facefucked many times back in the day, the feelings turned the older feline on in yet another way he hadn't expected this day. From being the one in control, it was now the kitten that pulled himself up and down, spearing himself while at the same time forcing his dad to deepthroat the fat log he had just moments before used to almost torment the kit. Tears were in his eyes and gags and sputters were coming from his mouth at the same time as his dick was serviced by the tightest and messiest hole he had ever experienced. Small bits were falling off and being swallowed by the kit, and eventually their lips met amid groans and moans and sputters and the smell and taste of scat and musky sweat from the dad whose unwashed musk was being accelerated by sitting in warm water and the workout he was getting from holding and fucking his kitten. 
The end of the turd in his mouth was comparatively softer, and the older tiger was able to mush it up with his tongue and re-consume his waste gradually, the sweet and bitter tastes reminding him of meals he had had days past. 
The sounds of his dad choking on his own waste, the musky and naughty scents, the man-poop going into his stomach and assaulting his taste-buds, the hard dick in his bum, all was pushing the kitten closer and closer to orgasm. Each jolt when being hilted and having his prostate massaged, the soft and warm and filthy bellyfur his cocklet was grinding against, the sounds of copulation, all of his senses were overloaded with erotic naughtiness and his orgasm was moments away.
The father could feel the contractions in his son's ass as he came closer to orgasm and his own was not far behind. As the spasms in the kit's ass became stronger he increased the force and greatly sped up his rhytm, his paws holding the kittens bum almost in a death-grip and his barbed and filthy cock hammered away, their bodies slapping together, moaning into each other's filthy mouths as they reached their orgasms simultaniously. The young boy's ass tightening up rhythmically to the convulsions of the grown man's dick, moaning into his daddy's mouth who in return was growling like a predator in the jungle, driving his dick hard and deep again and again to the rhytm as spurts of semen was ejaculated deep into his son's bowels, while the cocklet spread its semen into the filthy belly-fur.
Still connected on both ends, they kept kissing and sharing the filth for several minutes, both of them breathing heavily and both getting a little queezy from the amount of scat they had consumed and their strenous excersize. Eventually daddy's dick softened enough to plop out and they both took it as a sign that it was time to take a rest from their filthy fun.
The kitten was gently lowered into the now not-so-bubbly water, which had a certain brown tinge to it, and the father turned around and pulled the plug out from bottom of the tub.
"I think we need some fresh bathwater for this mess," he said with a grin and he looked lovingly at his naughty son who was covered from face to toe in brown streaks of caked-up scat that almost covered his bright orange fur.
Bright white fangs shining in between brown grinning to him was the only answer.
