The Buizel swiftly ran inside of his home, he was panting from running so fast. He looked over to the clock on the wall and studied it for a second, he then smiled wide.
"Growlithe, come quick! We only have thirty minutes before mom gets home, we gotta hurry." The Stud of a canine walked out from the hallways and pounced over to the Buizel. 
The Buizel starts heading off to his room, but then looks over to the couch. "Fuck it, this is faster." He quickly jumped up onto the couch, throwing his school pouch off his thigh and wiggling his ass at the Growlithe. "C'mon, boy. 30 minutes, no knotting, though!" The Buizel squeaks.
The Growlithe barks, seeing the Buizel give up his ass. He pounces onto the couch, showing off his large knotted canine shaft to the Buizel, his large bushy tail wagging. The Growlithe leans forward, licking his lips as he stares into the eyes of the Buizel. He begins thrusting in and out of him slowly, wanting to take his time.
"We don't have time for slow, fuck me like a fire type, mutt, c'mon!" The Buizel whines, begging for it.
The canine quickly takes the Buizel's demands, he starts pounding into him, his knot now bulging from his sheath with every thrust. He slams into him with all of his might, causing the couch to slam into the wall with a loud thud. The couch begins to leave marks on the wall from the force.
"Ohhh, that's it! That's it!" The Buizel cries out in ecstasy.
The canine begins panting and growling with each thrust, the sweat dripping down his face as he relentlessly takes the Buizel. He starts going faster and faster, leaving scratch marks all over the thighs of the Buizel. The two can barely contain themselves anymore, the both release their attractions as they howl and moan with pure ecstasy. The Growlithe releases a barrage of white liquid into the Buizel, filling him with his burning hot cum. The Buizel also releases himself, spilling his weasel milk all over his stomach and the Growlithe's wagging tail.
The two take a moment to catch their breath, the canine sticks his wet nose up to the Buizel's neck and begins licking it wildly. He starts whimpering and whining, wanting to please his master even more. "Uh.. fuck.." The Buizel looks back at the clock, they should still have 20 minutes left to work with. "Okay, go ahead Growlithe, but hurry.." 
The canine doesn't waste any time, he spins the Buizel around, pressing his body against the back of the weasel's. He slowly slides his body up against the furry stud, making sure to tease him and rub his entire body against him. The Buizel feels the bulge rise from the canine's body, he leans his head back and whines "C'mon, doggy! Just get inside of me." The canine obeys his master's commands, he quickly grabs his wet, throbbing beast and begins pushing it inside of the Buizel. He thrusts in and out with great force, he grunts with each thrust as he builds up a rhythm. The Buizel can feel his canine's knot begin to swell, threatening to pop out at any moment. The Buizel reaches his paw back, trying to keep the knot from popping out and blocking him up.
The canine begins panting, he lets out a loud moan as he releases his burning hot seed inside of the Buizel. The weasel sighs in ecstasy, enjoying the warm sensation of being filled with the Growlithe's love. The canine begins slowing down his thrusting, but this was a trick. Feeling the Growlithe slow down, Buizel removed his paw from blocking the canine's knot. At that very moment, the Growlithe smirked and slammed his hips forward, knotting the poor little buizel.
"AHH, get it out, get it out!" He cries out.
The canine begins laughing, enjoying the sound of the Buizel's cries. The weasel tries pushing against the canine's firm butt to get him to pull out, but it's no use. The canine begins slowly and painfully pulling out, the bulge in his knot stretching the poor Buizel wider as it passes his opening. He feels his insides being stretched as the canine's knot slowly makes its way out. Once he was finally free, the Buizel let out a loud sigh of relief, but this was short-lived.
The Growlithe snorts, as if to say "Aww, you didn't like that?" The canine pushes his master down to all fours, and turns the buizel around, pressing his knot against the weasel's opening. He then smirks, and growls in his ear also as if to say, "You'll love this, then."
He promises, as he once again rams his bulge into the poor weasel, who cries out in both pleasure and pain. The canine begins thrusting again, this time going deeper into the weasel than before. The Buizel grits his teeth and closes his eyes, preparing for another round of burning hot pain. The canine begins going faster and faster, making sure the Buizel can feel every bit of him. The canine's knot stretches out the weasel's entrance again, making him wince in pain, but the canine continues on. 
"G-Growlithe, we have to stop now.. Mom is going to be home any second, please!" The poor pup cries. This is responded to in the way of the Growlithe's paw standing on the side of the Buizel's muzzle, using it as leverage to fuck the poor thing harder.
He continues, ramming his bulge into the Buizel with force. The sound of two sets of wet balls connecting fills the room, along with the Buizel's yelps and cries. The sound of a bell ringing can be heard outside, signaling that the Buizel's mother has arrived home. The canine continues on unfazed, he seems to love the fact that this is occurring.
"G-growlithe, please! You have to stop!" The Buizel cries.
The canine begins grunting, building up to release his burning hot lava cum once again. The bell sounds again, this time it's followed by the front door opening.
"Oh, honey! I'm ho-" The Buizel's mother is cut off as she walks into the living room, witnessing her son getting railed by the family dog. 
She stands there for a second just looking at the sight of her pathetic son and the Growlithe balls deep in him. The mother Floatzel seems to think for a moment before giggling, walking over and petting the Growlithe's head. "You too? I honestly took you for more of a top, but this kinda makes more sense. Your father isn't always the most interesting in bed, so sometimes this little guy is a good replacement." She leans down and whispers in the Buizel's ear slyly, "though, I'm usually still the one on top." 
She looks back at the canine, who's still pumping away. The Growlithe begins panting, and soon he lets out a growl as he shoots his load into the Buizel once again. The mother Floatzel helps him out by grabbing the Growlithe and tugging him backwards to pop his knot out, making her son squeak out. 
"Well, I'm taking this little guy to my room for my turn," She smirks, holding up a strap on from her bag, the Growlithe letting out a small whimper. She starts walking away and stops in the entrance to her room, "Oh, and you don't tell your father and I won't either, sound good?" The Floatzel smiles at her son.
"Y-yep.." He cries, and the mother heads off to fulfill her needs. The Buizel sighs in relief, flopping back onto the pool of cum on the couch.
