There is a Buizel who lives at home with his Lucario mother and Floatzel father as well as his little Riolu brother. They also have a Poochyena as a pet that lives in the backyard. The house itself has a small garden and an outhouse for the animals.

The Buizel was home alone, laying down in his bed as the Poochyena pet jumped up onto the bed and started licking his muzzle. 
The Buizel giggles softly and licks the Poochyena back, his tails waving in the air. The Poochyena then
Lifts up his leg and shows the Buizel his huge knotted doggy cock, the Poochyena huffing lustfully.
The Buizel seems a bit confused by this and looks up at the doggy beast with a tilt of his head, not knowing what to do.
The doggy looks down disappointedly and drops his leg, then turns around and walks out of the room, whimpering all the way.
The Buizel sighs 
"Wait... Come back, Mutt, I can help you with that... If you really need it?" The Buizel whines.
The Poochyena immediately perks up and jumps back onto the bed, staring at the Buizel eagerly. The Buizel chuckles and moves closer to the Poochyena before they start passionately kissing, rubbing their wet tongue together.
The two have their fun as the Poochyena eagerly huffs into the Buizel's muzzle. After a while of this the two are ready, and Buizel flips over, exposing his hole to the Poochyena.
The Poochyena instantly drops his weight as his large red dog schlong drools out, the fur around the base looking quite matted down and smelly. The Poochyena leans forward and starts to rub his wet nose on the Buizel's pink starfish, making it expand a bit as it gets wetter.
The Poochyena then licks all around it, making sure it's wet enough before he starts to push in.
The Buizel whines and spreads his legs out, "Try to go easy on me, okay Pooch?"
The Poochyena just whimpers and presses in further, his tongue lapping at the Buizel's taint as he begins to enter.
The Poochyena pushes until his knot is pressing up against the Buizel's butt, the whole area wet with slobber. The Poochyena lets out a small whine as he holds still for a moment, making sure he won't slip out during their fun.
The Buizel's pink hole is completely spread open, showing a deeper pink as the Poochyena's knot pokes in and out slightly. The Poochyena then begins to hump slowly, letting out small whines as he begins to work his hips.
"Ooohhh.... Yeah...." The Buizel moans, wagging his tails as he gets pleasure from the doggy's schlong stuffing his hole.
The Buizel takes a deep breath, choking on the doggy's musk. He keeps sniffing at the musk as he squirms about, rubbing his nipples with his front paws.
The Poochyena starts to hump faster, his knot tightening as he pushes it in and out with greater speed. The wet squishing sounds are very loud as a puddle of slobber begins to form underneath the two canines.
"I-It's... It's happening! I'm going to...." The Buizel pants, his eyes glistening from the pleasure.
The Poochyena speeds up even more as he begins to shove his knot in even faster, beating the Buizel's cheeks. The Buizel lets out a loud yelp and begins to pant heavily. His tongue hangs out as he pants, looking over his shoulder at the Poochyena with half-lidded eyes.
"I-It's happening now! I can't stop it!" He cries, his legs beginning to quiver.
"Knot me, mutt! Knot me and never pull out! Give it to me, please!!" The Buizel orders loudly, his legs beginning to shudder as he lets out a high pitched moan.
The Poochyena rams his knot in as far as he can as it pops inside, locking into place. The Buizel's whole body begins to quiver as his legs lock in place, his paw hands balling into fists as he begins to yelp.
The doggy's knot swells up inside the Buizel's hole as the doggy lets out a loud howl. The Poochyena's own hole pulsates as he releases his doggy juice deep inside the Buizel.
The Poochyena slumps down, falling on his side. His tongue hangs out as he pants, the top half of his body covering the Buizel's backside.
The Buizel lets out a long sigh, "Th-That was good... You're one hell of a stud, mutt..."
The Poochyena looks over and barks, wagging his tail as the Buizel leans forward to sniff at the doggy's musk. He takes in a deep breath as he licks up the doggy's leg.
"You taste really good... Mmmm... I want more..." The Buizel says with a lick of his lips.
The Poochyena barks in reply, lifting his back leg as his stumpy red member hangs out. The Buizel starts to sniff and lick at it, cleaning off the doggy precum that leaked out. Poochyena barks as the Buizel's pink tongue cleans him.
"That's a good boy... Good boy..." The Buizel says as he continues to lick and suck on the doggy's member.
The Poochyena soon stands up and begins to hump the Buizel's face, shoving his whole red member into the weasel's mouth. The Poochyena holds the back of the Buizel's head as he begins to thrust, beating down the back of the Buizel's throat.
The Poochyena barks as he plows the doggy's mouth, his knot bulging as it begins to expand. The Buizel's throat bulges with every thrust, as he continues to gag.
The Poochyena lets out a howl and barks loudly as his knot swells even more, forcing itself down the Buizel's throat. The weasel begins to choke and gag on the doggy's member as the doggy's bulging sack expands.
The Buizel's muzzle and nose is shoved into the Poochyena's knot and balls, the smell of musk making the poor buizel light headed.
The Poochyena lets out a short yelp as his knot bulges and explodes, releasing a torrent of dog jizz that floods down the Buizel's throat and into his stomach. The doggy's red member continues to expand, blocking off the Buizel's airways as it forces itself down the weasel's throat, cum blowing out both of his nostrils.
The Buizel's body goes limp as the Poochyena pulls his swollen member out of the weasel's mouth, releasing a torrent of jizz that splatters all over the side of the Buizel's face and the ground. The doggy's red member then begins to shrivel and pull back into his sheath as he lets out a sigh, before collapsing on the Buizel.
The mutt's musky crotch was laid directly on the Buizel's poor nose. The musky smell of a true alpha was enough to send the young weasel into a coma.
With the two canines asleep, the ground a puddle of canine seed, and the weasel's nostrils plugged with doggy jizz, all that remained was for nature to take its course.
