It was mid-day and Sabonaba's G-type main sequence star, Njoku, shown brightly on the green expanse of the Sen-Rakham Farmstead. The sky was nearly cloudless, no more than a few streaks of white against the brilliant blue. The heat was tempered by a gentle breeze that rustled the branches of the tall fir trees bordering the sprawling fields. A smaller field, much less orderly and clearly distinct from the precise rows laid down by auto-tractors across the bulk of the farm adjoined the salmon-colored faux-adobe farmhouse. A lone biped, brown-furred and of spotted hyena template, was crouched down in one of the herb beds with a weed puller.

Bo Rakham's hyaenid ears perked up, he heard the car's tires crunching down the gravel drive long before he saw it. He glanced at his watch and the small holo-notification told him that Niva was about to arrive home. 

Right on time, he thought with a smile. The hyena-morph stood up to his full 2.3 m height, returning the weed puller to a pocket of his dark green gardener's apron and picking up the basket of basil leaves and tomatoes. He adjusted his wide-brimmed sunhat, and began making his way back towards the house. He was just past the side door to the kitchen when a dust-covered white van spray-painted with the words “Sabonaba Colonial School Administration” rolled to a stop in front of the farmhouse, Bo continued past the side entrance and began walking towards the drive. 

He rounded the corner of the front porch and stopped to watch as the door of the driverless van slid open and out hopped a pudgy, chocolate-furred neorat teen. He was dressed in the ‘special occasion’ uniform of the colonial schools, a blue jacket with the planet’s wheat-and-cornucopia seal over the right breast and a pleated skirt hanging down passed his knees, a backpack was slung over one shoulder and a large duffel bag hung from the opposite hand. After saying his goodbyes to some fellow students he slid the van door closed, swung around, and broke into a sprint as soon as he saw Bo.

Bo braced himself for impact as the neorat barreled into him, dropping his duffel bag, and immediately wrapping his arms around the large hyena’s waist.

“Ooof, careful there pup!" Bo said with chuckle, "You’re getting pretty big!” Bo returned the hug and placed a kiss on the top of Niva’s head.  

“Hehe, sorry Papa, this trip just got me thinking about next year.” Niva slowly let go and went to pick up his duffel bag, but Bo beat him to it, grabbing the bag with one hand and the basket with the other. 

Next year, Bo thought with a bit of apprehension, he’ll be 16 already, off to spend 6 months on the homeworld with a 3 month voyage there and back.

“I know a whole year away seems like a long time...but half of it will be in hibernation." Bo said, as they made their way into the house through the side door.

"It goes by like the blink of an eye. And Earth is an amazing place!" By this time they had reached the kitchen and Bo had put down the basket on the kitchen counter. 

"You’ll experience so many things. Cities, I mean real cities, ancient ruins..." He placed Niva’s duffel on one of the kitchen stools, tossed his sun hat onto one of the pegs protruding from the kitchen wall, "... you'll get to ride down from orbit on one of the biggest space tethers in the galaxy ...and the food there is incredible! Variety like you can't even imagine!  You’ll be so busy experiencing all that you'll be home before you know it.” Bo wasn’t sure if he was trying to reassure Niva or himself more.

“Yeah, I guess… it’s exciting..." Niva said with some uncertainty, followed by a pause,"...and a bit scary… I just want to spend as much time as I can with everybody before I go!”

“Of course kiddo! Speaking of, since Randy and Kevin’s classes are still on their trip and dad is off chaperoning it, we have the house all to ourselves tonight! Which means…”  Bo quickly took off his apron followed by his loose-fitting shorts.

Niva grinned as he looked his papa up and down. The brown-furred, spotted, and slightly chubby hyena was now completely naked save for a white, puffy cloth diaper wrapped around his waist. Niva immediately removed his school jacket and hung it on the stool over his duffel bag, next came his shoes and finally the undershirt and pleated skirt which were piled atop the duffel bag to be put away later. Niva was now similarly bare, with the exception of a pink cloth diaper just like his papa’s.

"Well, look at you! I see we both planned ahead." Bo smiled, loving just how adorable his boy always looked in nothing but a diaper. Niva, of course, looked a lot like his neorat dad Hari, but there were clear indicators that showed where the reproductive clinic had incorporated Bo's phenotype into the engineered egg that Hari's sperm fertilized. His chocolate-brown fur, tendency towards a slightly pudgy belly, and the way his long, pink rodent tail always curved slightly near the end the same as Bo's hyena one all created a clear resemblance between Niva and his 'yeen papa. 

Niva ran over and wrapped his arms around Bo once more, this time nuzzling into his soft belly fur and inhaling his familiar, earthy scent. 

“Guess somebody was ready for diapee night, huh” Bo chuckled as he wrapped his arms around Niva.

“Mmmf, yeah” Niva giggled, his eyes closed as he continued to nuzzle Bo’s belly fur and inhale his scent. 

Diapee night had been their tradition, especially whenever the others are out, since Niva was little. While no one in the Sen-Rakham household had any hangups about where they did their business (so long as it didn't get on anything hard to clean) neither his hyenamorph younger brothers, Randy and Kevin, or their neorat dad Hari held the same fascination with diapers that Bo and Niva did. When they first moved from Earth some nine years ago the then-six-year-old Niva was already potty trained, but three-year-old Randy wasn't. Disposable diapers are basically unheard of on a young colony like Sabonaba, so they switched to washable cloth but soon found that Randy would constantly take off his diapers and Niva would constantly put them on. They also realized rather quickly that it was much easier to clean young Randy's notoriously sloppy dumps off of the easy-clean floor than it was to clean the 'yeen toddlers butt-butter out of his fur. By the time Kevin was born the diaper collection had long since been relegated to being Niva and Bo's occasional indulgence.

“Come on, let’s watch something, whatever you want” Bo guided them out of the kitchen and over to the couch in the living room. He pulled out a towel from the stack under the end table, laid it over the couch, and reclined on it, propping himself up on his elbow. Niva nestled himself in front and slightly on top of his papa with his legs between his papa’s larger ones and his padded rear resting against papa’s equally padded crotch. Niva’s long rat tail was already raised up and sandwiched between Bo’s belly and his own back.

Bo reached down and began gently rubbing his son’s belly, running his hand through Niva’s soft belly fur in small circles. Niva had his fone out and was already pulling up one of his favorite movies on the wall screen, part of a series of documentaries about the nature preserves on Earth. This particular one focused on an elephant preserve in southern Africa and had a whole segment studying sexuality with great, close-in shots of the action.

They laid quietly for a while, the intro to the documentary played through, Bo half watched the familiar image on the screen of an elephant bull’s cock jumping and pulsing as he ejaculated into another bull’s clenching ass. Niva had his eyes closed completely as he relaxed into his papa’s gentle belly rub. Relaxing like this would be hard with the others around, by this point Kevin would undoubtedly be asking Randy to hold an empty plate or bowl under his butt so he could blast some turds into it, Randy would probably be loudly pumping his slick teen yeen pole and getting ready to spray another volley of his copious boy batter across the livingroom floor. But with just Bo and Niva home they could bask in the peace and quiet.

Pfffffffft. The fart was barely audible but the burst of warmth against his crotch caused Bo’s hard cock to throb against the padded front of his diaper. The sulfurous stink of rotten eggs wafted up to his snout.

He rumbled in his hyena purr “Dookie time, huh kiddo?”

“Nnnngh…y…yeah. Couldn’t go during the last couple days of the trip. Hard to go on a spaceship I guess.”

Bo reached down and gently lifted up Niva’s leg while his other hand continued the gentle belly massage, only now applying just a bit of pressure.

“Yeah, I always had trouble going on ships," Bo said, as he continued rubbing his sons soft belly fur in a circular motion, "that centripetal grav messes with my guts too. Just relax babe…gentle pushes, don’t force it”

“Oh…nnnnngh…kay” Niva’s knees pulled up towards his belly reflexively and his toes curled as he tried to relax his hole and gently push. 

After letting out a few more bursts of gas, Niva could feel his hole spreading around the tip of a thick, solid log.

“It’s…hnnng…coming…nng…” with another grunt and a little more pushing the log began to slowly slide out and into the waiting diaper. 

“Ahhhh” once with the initial ‘plug’ was out of the way things started to move much quicker. The solid log turned into a soft shitsnake that quickly filled up Niva’s padding.

Bo could feel the warm, soft load expanding against his crotch as his erection squirted jets of pre into his own diaper. “There you go buddy, push it all out.” Bo’s hand moved down from his son’s belly to the throbbing mass between his son’s legs, gently squeezing the hard, pulsing rat boner through the front of his boy’s diaper.

With one last grunt Niva pushed out the last of the soft rodent clay, feeling it mush into the packed diaper.

“Ahhhh” Niva sighed in relief and gently humped against his papa’s squeezing hand, feeling his load mush against his papa’s padded crotch each time he moved back. Niva and Bo both closed their eyes and rested, Niva basking in post-shit relaxation while both were engulfed in the familiar stink of a well loaded diaper.

Just as Bo opened his eyes and was about to ask Niva if he was ready for a change he heard Niva’s stomach give a loud gurgle. “Hmm, bit more?”

Niva felt a sudden abdominal cramp and a burning in his belly heading south quickly. He gave out a long moan, “ohhhhh, feels like more than...nnnng... a bit….nnnnngh” Niva began to instinctively curl his knees up towards his stomach, pink rat toes curling as the storm in his guts headed towards his rear exit.

Bo quickly reached down with his right hand and grabbed the soft, warm bulge in the rear of Niva’s diaper, pulling it out slightly to give him a bit more room to push out this next batch of mess. His left hand went back to squeezing Niva’s throbbing erection through the front of the diaper. 

“Ohhh…nnnngh…fuck!” with a loud SPLOOOOOOOOORT Niva doubled over and the teen rat's ass fire-hosed a wet, chunky slurry into his already full diaper. Bo felt his son's whole body tense and his diaper expand even more as he blasted out days worth of sloppy rat shit. 

"Dang buddy! You really needed to go, huh?" The first geyser was followed by smaller squirts, each one causing Niva to tense and push, adding the muck to his packed diaper with a squelch. The rhythmic cramping in Niva's abdomen was being matched by the squeezing of his papa's paw on his padded cock, mixing surges of pleasure with the painful cramps. As quickly as the shitstorm started it was over. Bo could feel that Niva's padding was pretty much packed to the limit and he was pretty sure he could feel some warm, wet leakage on his inner thigh from one of the leg holes.

Niva lay panting for a moment as the belly cramp subsided. "Hehehe...wow...that was...he...more than I thought it was gonna be."  Bo chuckled as well, giving the throbbing boner in the front and completely filled seat in the rear of his sons diaper gentle rubs. "I think it's changing time kiddo."

"Yeah, here" Niva carefully rotated himself around in place so he was facing his papa, their two padded erections pressed together but neglected for the moment. He reached behind his hyena dad and grabbed onto the towel they were laying on while Bo reached down between their legs and pulled the other end of the towel up to Niva's back so that it was wrapped under both of their diapers. 

As Bo sat up on the couch Niva wrapped his legs around the big hyena's waist and both arms around his chest. Bo had both arms wrapped around the smaller rat teen and, with a quiet grunt, he stood up, taking his boy and the towel with them. He quickly walked them to the bedroom, using the towel to trap any falling mess, where he layed the towel and Niva down on the bed face-up. 

As he was reaching for the velcro tabs on the side of Niva's pink diaper his son grabbed his hand, "hold on papa...nnnng...little bit more" Bo smiled and watched as the black furred rat teen lay with his eyes closed and his brow furrowed, looking much like he did when he was pushing out some pre-change turds as a little cub. Splrtch. The sound was barely audible through all the mess already packing the diaper, but Niva had definitely added at least one more small squirt to the sizable load.

He let go of his papa's hand and sighed "O.k., now I'm ready" The hyena leaned over and planted a loving kiss on his messy rat sons forehead before resuming his unzipping of the diaper flaps.  As soon as he got them undone the teen rats raging hard-on pushed the diaper's front flap open with a splat. Niva giggled and Bo starred in awe at the massive shitload coating the entire bottom and rear of the diaper. Niva's ass, inner thighs, and the backs of his pendulous rodent balls were also painted light brown with a thick slathering of the freshly extruded gut batter. 

His sons cock, now freed from the confines of padding, stood throbbing and leaking, the smooth, pink length already covered from sheath to rounded, tapered tip in glistening precum. Just as Bo began to reach for the glistening length he felt a familiar fullness in his lower intestine, the feeling of a load knocking at his back door suddenly made itself known.

"Nnnngh...got a special show for you Neev" the hyenamorph got up onto the bed, turning around and kneeling over his son so that his padded ass was over his boys chest while the teen rats throbbing meat was directly in front of him.

"Oooo! You gotta go too papa?" Niva asked excitedly. As if in answer Bo's ass let out a loud brrrrrrrap. 

Niva giggled as a wave of shit-stink washed over him. 

"Nnnngh, yeah kiddo, didn't take my usual garden shit this morning" Bo's tail began to flag as he reached down and wrapped his hand around his son's cock, feeling it throb and leak precum over his fingers. As he gave the teen's erection slow, gentle strokes he began to push as well, feeling his own load move quickly towards his ass.

The hiss of escaping gas emanated from the base of Bo's flagging tail. It was quiet when Niva heard it but to be audible through the thick padding it must have been quite the geyser. The strong odor of hyena shit now overpowered the smell of rat waste permeating the bedroom. "Ohhhh, sorry there kiddo, guess I'm a bit gassy"

Niva's hips twitched almost involuntarily, gently humping his dripping cock into Bo's already pumping fist. "NNNNnnngh...t-that's f-fine papa...mmmmf...push it out, I wanna see". Niva grunted out through gritted teeth, he was dangerously close to cumming and was struggling to hold back.

"Nnnnnnnngh" Bo gave a grunt and another push. At first it was just another loud fart, another booming brrraaap of gas but that quickly turned wetter. Soon enough the loud, bassy fart pitched up to a squeak and than was replaced by crackling as Bo's anus finally stretched open and he expelled a thick log of semi-solid hyena clay into his purple padding with a crinkling sound. Niva's eyes were locked to his papa's padded ass, just tens of centimeters from his muzzle as he smelled the familiar stink of fresh 'yeenmorph shit and watched his papa's purple padding expand from the sizable load.

"Little more kiddo" With another soft grunt he bore down expelled the last bit of mushy hyena exhaust into his padding, feeling it mash onto the log already parked there. Focusing his attention back on his sons now rapidly pulsing boner, he increased his stroking speed. His boy was now a veritable fountain of rat pre, his hand was completely soaked as were the teen's balls. Those balls, he noticed, had tightened up considerably as his experienced hand brought his son barreling towards the brink.

Soon the rat teen's legs were giving the telltale pre-orgasm twitches, his breathing was coming in short breaths, toes curling...

Niva's eyes were closed so tight he was seeing stars as his orgasm hit like a missile. His hips thrust straight up into his papa's stroking hand and the first, powerful blast of cum shot straight up, spraying Bo right in the muzzle. He was able to catch some of the salty stream on his tongue but most of it streaked up the side of his muzzle. The next shot was nearly as forceful as the first but by that time Bo had aimed his sons squirting length towards his chest. His son continued to jerk, twitch, and give little involuntary humps as he painted his papayeen's chestfur with 6 more heavy shots of teen rat spunk. 

After the main eruption subsided, Bo continued to give slow strokes while Niva continued to twitch and pump out a stream of lower pressure cum, each squirt more of a gush that poured down over his papa's already soaked fingers. When the stream started to die down, Bo let his son's slowly softening cock flop down onto his belly fur and started to carefully maneuver himself off the bed. He didn't get far before he felt the familiar sensation of Niva's hand grabbing and rubbing the outline of his own throbbing erection through his padding.

"Ohhh...you know...nnng...you don't have to return the favor, I'm always...nngh...happy to help my little guys out!" Bo said, through grunts and moans, but made no attempt to move away from the boys groping paw.

Niva, who had heard this little spiel countless times, merely rolled his eyes and started to work the waistband of his papa's diaper down. "Less talking, more giving dick!"

Bo chuckled and positioned himself so he was kneeling next to Niva's head, "Alright, alright, I know not to get between a hungry ratboy and a snack", he pulled the diaper down the rest of the way, letting his long, black-skinned hyaenid phallus flop out into the teen's waiting hands.

Niva immediately started to rub the heavy, pre-slicked organ along the side of his muzzle as he inhaled the thick, masculine scent emanating from his papa's shaft. As he began to lick down the underside, coating his tongue in the familiar, salty essence, he felt the hefty tool pulse and release another gush of precum down the side of his muzzle. His papa was getting close already.

Bo grunted and confirmed his son's suspicions, "H...hey buddy, mmmmf, not gonna...last long after that big show you put on" the towering hyena let his tongue hang out of the side of his muzzle and his eyes were unfocused as he stared at the heaping mound of rat shit between his boy's legs. 

Bo inhaled sharply, his nose filling with the thick, overpowering stink of their mess permeating the room, as over half of his 1/3 m length was suddenly engulfed in slick warmth. He snapped his focus back to Niva, who had, in one motion, swallowed over half of the throbbing hyena cock. The teen rats eyes were shut and he swallowed repeatedly to try to keep up with the now-continuous stream of pre. One of the boy's hands worked the remaining centimeters of exposed shaft while the other gently cupped his papa's quickly tightening sack.

"Mmmmf...b..buddy, ohhh....here it...unnnf" Bo's hands went to his hips and he had to actively keep himself from humping into his son's suckling mouth. Niva increased his sucking, gulping down the river of precum in preparation for the coming flood. With a sharp inhale and a grunt Niva felt the first blast of his papa's cum shoot directly down his throat. This is was quickly followed by another pulse and another sizable gush, only this time Niva had backed off slightly so the warm, salty cream would fill his mouth instead. He knew he didn't have long to savor his snack and he swallowed just in time for the next burst, this one less forceful but copious enough to fill his entire muzzle and overflow around the pulsing shaft, before he even had time to swallow the next wave was already exploding against his tongue. He tried to swallow it all but there was no keeping up, he sputtered around the pulsing shaft, cum leaking out of his mouth, flooding into his sinuses and running down his nose. Still, he kept swallowing, gush after gush, pulse after pulse, Niva was lost in a haze of bliss, drinking down the as much of the hyena protein as he could, suckling like a hungry calf. 

When the flow finally tapered off neither of them could tell how long had passed, probably minutes but it felt like seconds and hours all at once. Bo's shaft quickly began to grow sensitive to the aggressive suckling and he pulled himself from his boy's maw with a wet slurp, the blunt tip of his shaft exiting with a loud pop. He looked down at Niva, his brown-furred muzzle completely soaked in his seed, his eyes still closed as he swallowed repeatedly to clear the remnants of his papa's large load from his mouth. Beneath his muzzle a small puddle of sticky 'yeen cum had gathered on the towel. Bo bent down and cleaned his mess from his son's face with slow licks of his broad tongue. Niva giggled but obligingly turned his head the other way for Bo to clean that side as well, once all of the hyena ejaculate had been thoroughly licked off (and replaced with a not inconsiderable amount of hyena saliva) Bo leaned back and sighed.

"Whew, thanks kiddo, you're catching up with your dad on that front," Bo pulled his diaper back up, feeling the turds  smush against him as he did. He slowly made his way off the bed and grabbed their clean-up supplies off the dresser, heading back to the end of the bed by Niva's feet. Niva lifted his legs up, exposing his messy, shit-covered hole.

"Yeah, if you say so, but dad never leaves a big puddle laying around when he sucks you off" Niva said has he gabbed his own ankles to give his papa better access to his messy undercarriage. Bo began using the biodegradable wipes to clean the wet shit from his balls, taint, and ass. He wasn't too thorough since they'd be showering, he just got enough off that Niva wouldn't drip all over on the way to the shower. 

"It took your dad a looot of practice to be able to handle my output as good as he does" Bo dropped the dirty wipes on to the shit pile in the diaper and began to carefully wrap it up. Once that was out of the way, Niva sat up, taking care to only touch the towel, and stood. He threw his arms around his papa once more, pressed his snout into the soft belly fur, now even muskier than before and mixed with the distinct scent of his own rodent batter. Bo dropped the carefully folded and very full parcel of rodent muck onto the towel and wrapped that up as well before they both headed off to shower as well as empty and hand-wash their well used diapers.

One thorough shower later and they were once again curled up on the couch, now naked and smelling of sandalwood shampoo with just the faintest undertones of shit. They would need to start preparing supper in a couple hours but for now they could just relax. Bo's hand was back on Niva's belly, petting his soft, well-conditioned, chocolate-colored fur into little swirls.

"Papa...that was really fun."

Bo planted a kiss on the top of his son's head "diapee time with you always is pup."

"I love our special time... but I can't wait for everyone else to get back tomorrow!" Niva snuggled back into his papa's warm fur and started to drift off, thinking of the fun he'll have tomorrow, when his dad and brothers get back.
