Gordie was at his computer, playing a video game when the door burst open and a booming deep voice yelled “FUCK!!” 

“W-what’s wrong?” Gordie asked. The short and chubby granbull had become used to his brother living with him in his summer apartment. He had also become used to his older sibling pushing him around, insulting him, leaving messes for him to clean. But this was something different than usual. His older brother was clearly angry about something.

The older granbull in question, Brandon was much bigger and stronger than his younger one, being huge and thick in every way, large muscular arms and legs along with a wide, plump musclegut. He was growling deeply as he stepped into the apartment and slammed the door, throwing his gym bag to the side. 

“Some twink bitch was all flirty at the gym, saying that he was gonna do this and that. Got me thinking I was gonna get my dick wet and when I head into the locker room where he said to meet me he’s nowhere to be seen. I looked all over and even waited a bit longer but he just up and left. Was probably laughing on the way out too!” Brandon seethed. 

“That’s messed up,” Gordie agreed.  

“Shut it, Runt!” Brandon snapped, marching right up to his younger brother. “Since that skinny bitch stood me up you’re gonna take his place!” The older and bigger granbull followed up his words by shoving his younger sibling’s head into his armpit. 

Coming back straight from the gym without a shower, the fur of his underarm was hot and wet. Gordie’s nose was forced against that and the raw, earthy musk was pouring into it. The bigger canine pokemon had no trouble holding the shorter and chubby one in place, forcing him to endure the reek of his pit that was in need of a wash. 

It all happened so suddenly. Gordie barely had the time to register what happened. One moment he was talking to Brandon and the next he was feeling all but smothered and attacking his sense of smell was a raw and masculine odor, so powerful that it was making his head spin. He took another breath and got his lungs full of the stuff, shuddering from the effect it had on him. He was both disgusted by this and aroused. Brandon was holding him firm and he knew why. There was something that the bigger bulldog pokemon wanted him to do...

Gordie could pretend that it was the worst thing in the world but there was a part of him that was pretty eager to make use of his tongue, stretching it out and touching it to the pit that was so wet with perspiration. The taste was deep and bitter as to be expected. This wasn’t his first time in this position and yet he could never get used to the biting flavor that would shock his taste buds. Gordie continued to lick, making his brother’s pit all the wetter with every swipe of his tongue. 

The more that he licked and sniffed, the more excited that Gordie felt himself becoming. His groans of disgust had died away and were replaced by soft hums of his voice and steady sniffing. Brandon noticed this and chuckled, pulling his brother’s head from his pit, allowing Gordie to take a breath of fresh air that was still tainted by the smell wafting from his older brother’s sweaty body. It was easy to tell that his musk had an effect on Gordie, from the way he was softly panting and from the obvious tent in his pants. Brandon let Gordie go and told him to get those pants off. The smaller fairy-type obeyed and got them and his underwear off, leaving himself bottomless. Between his chubby legs was his swelled sheath and the 4 inches that were peeking from it. 

Brandon grinned and proceeded to do the same. Wearing nothing but a tank top and shorts that were suitable for working out at the gym, it took hardly any time at all for him to get them off along with the large jockstrap that was fitting snugly to his crotch. While Gordie kept his shirt on, his older brother was completely nude. He towered over the younger granbull, standing at 7’ 2” while Gordie was just 5’ 4”. 

Gordie’s eyes scanned the other bulldog pokemon’s body, coming to rest between his large and bulky legs. His already fat sheath, paired with a set of large, wide, and low hanging balls, twitched and swelled as the dark flesh came sliding out, already looking shiny with a mix of sweat and sticky sheathgrime. Standing right in front of his smaller sibling, he simply reached out and grabbed hold of Gordie’s mouth, squeezing it hard on the sides, making his brother’s mouth open. 

When it did, Gordie felt something hot and incredibly thick being pushed into his muzzle, making it spread even further. He instantly knew what it was, shuddering from the sharp taste and smell of his brother’s phallus, coated in a sheen that had a strong enough taste to make him nearly retch and the smell of it was making his nose wrinkle and burn a bit. As his brother pushed his large knotted length inside, Gordie groaned from the elements becoming stronger, feeling the weight of it pressing his tongue down. It wasn’t just that Brandon was big down there, he was downright huge, measuring up to 19 inches that were impressively girthy all the way down, ended by an even wider knot. 

A single thrust was all it took to shove the length down into Gordie’s throat. Brandon groaned from the tightness, gripping the other granbull’s head and pushing it down, making him take more of his length. While feeling his throat being spread around the thickness, Gordie was also still taking in the deep musk that was wafting from the great endowment. The musk was no doubt strong and even offending but it was also oddly comforting and familiar. Brandon used to torment him all the time when they were younger, assaulting him with dirty clothes or shoving his head into his pit with the intent to gross Gordie out. 

Taking the smell in by the noseful, Gordie could feel his mouth watering around the unwashed flesh. A single thrust from Brandon snapped him out of it. That one push was all it took for several more fat inches to be forced down into his windpipe. Brandon began to thrust and Gordie’s oral cavity put up no resistance. He was used by his brother often enough thanks to them living together and his very body had become accustomed to his brother’s size. His orifices were pretty easy for Brandon to penetrate while also remaining tight around him. 

A jet of thick, slimy precum shot from the tip and down into the bottom of Gordie’s stuffed throat. To the smaller granbull’s credit, he had grown accustomed to the size and could breathe without issue around the incredible amount of girth and by doing so his nose was being filled with even more musk. The excitement of doing this along with swallowing down the precum was making his own cock throb and leak as well. 

His head was pulled back and the shaft was sliding from his throat and over his tongue, now coated in a layer of thick precum in addition to everything else. Gordie started to lick it, acting on what he essentially was trained to do, acting on his brother’s known desires. He expected the shaft to be pushed back into his throat but that didn’t happen. Another pull backwards tugged the length fully from the chubby granbull’s muzzle. 

Brandon got behind his brother and picked him up effortlessly, keeping a hold on him so he could maneuver Gordie’s body, getting his throbbing cocktip aligned with the smaller and lighter purple canine’s tailhole. The large and shiny cock was coated in various fluids and was still leaking precum that was thick, slippery yet also sticky like a mix between honey and oil. Brandon rocked his hips and in doing so he was also grinding his cock in between Gordie’s soft and chubby asscheeks. 

“Ready?” Brandon asked, speaking directly into the other granbull’s ear. 

“Y-yeah...” Gordie nodded, feeling his heart pounding in his chest. 

Brandon would have gone ahead either way, grunting as he pushed upwards, getting his tip to press against the rim and spread wide around it. Another push jammed nearly all of the cock’s length in at once, stretching Gordie’s ass even further, making him yelp from the mix of pain and pleasure that coursed through him. His body was stretchy enough to handle his older brother’s size but he still had to endure the force that Bradon would apply, always more concerned about his own pleasure over anyone else’s. 

Gordie was gaining pleasure as well from his prostate being pressed down on by the great amount of girth. He groaned and released more precum from his own cock. Throbbing inside of him, more of his brother’s length was being fed into him. When more than half was inside, Brandon began thrusting, bouncing his younger brother’s body while also feeding the rest of his cock in gradually until his knot was also slapping against the younger brother’s stretched rim. 

“Good thing I’ve got a weak, slutty little brother to serve as a substitute,” Brandon chuckled to himself. 

Gordie just groaned in response, feeling the thickness sweeping along his sensitive walls and over his prostate with every pull and push. The thrusts came in fast and hard. Brandon was putting his muscles to use, flexing them as he continually rocked his lower half, repeatedly smacking his own body into Gordie’s. Being at his older brother’s mercy, Gordie was smirking against his sibling’s large belly, biting his lip and moaning from the mix of pleasure and humiliation that was coming his way. 

“Fuck yeah...” Brandon muttered, gripping his younger brother’s body and thrusting in even faster and harder, plunging his cock all the way down to the knot, making it slap against his rim over and over again, making a firm wet sound every time the bulb made contact with the soft pink rim. Gordie’s hole was squeezing down on his shaft, milking out of his precum at a near constant rate.The excess was leaking out when his hips would rock either way, dripping down his knot, sheath, and balls. 

“Rrrggh!” Brandon snarled, putting even more force into his next thrust. 

“Aaaugh! W-wait!” Gordie’s pleading fell on deaf ears. He felt the knot being pressed firm against his knot before more strength had been applied. It happened quickly but time seemed to slow down for him. His rim was slammed against and the knot was being ground against it. Then it gave way, unable to hold firm against the bigger fairy-type’s power. In real time it wasn’t any longer than two seconds and yet Gordie was left shaking and whining from the sting of being knotted by the huge bulb. 

Brandon didn’t stop when it popped in, keeping on with his steady rhythm, grunting and huffing as he continued to stretch his brother out further, now using all of his inches at once to penetrate him. The tightness of Gordie’s ass had increased and he was loving that, not being able to stop even if he wanted to. Keeping at the pace but adding a bit more force with the passing of time, Brandon was fully indulging himself in the pleasures of his younger brother’s body. 

Meanwhile the pangs of pain from the knot being wedged in had died down, being eased away by the strong waves of pleasure that came from every thrust that rubbed against his walls and pressed on his prostate even harder. Having it being touched and kneaded so much by his brother’s thickness was starting to get him close to his climax. 

“Gonna cum? I can feel your ass clenching hard,” Brandon said with a low chuckle. He had no trouble holding his climax at bay for a bit longer, still rocking his hips roughly and slamming his cock and knot in as deep as they all would reach. The bulb would slide from the rim, popping out and then a push would come, making the knot pop back in again. 

As the knotfucking continued Gordie was forced to cry out and shoot his load, experiencing an intense hands-free climax that had him releasing ropes of cum onto the living room floor. This made his ass clench even tighter around his brother’s fat cock. Brandon’s growls were becoming more intense as he picked up the pace even more, stuffing his knot back inside and keeping it in there as he let out a deep reverberating growl. His cock swelled and pulsed hard, pumping thick loads into his brother’s tight ass. 

“Take every drop!” Brandon snarled. He pressed his hips upwards, still grinding his pulsating and shooting cock along the hot and clenching walls. They were actively milking his length as the loads were coming out. The heat of his own gooey loads were rushing into the snug passage, flowing back around the cock it was coming from but all of it was staying inside because of the knot. Goride could feel himself being filled up while his brother was grunting and huffing directly into his ears. As the flow of seed kept coming from the throbbing spire, Gordie could feel his stomach starting to swell from the sheer amount. 

“It’s over now,” Brandon said. Now that his seed was spilled he was getting a bit annoyed with Gordie’s groans and whimpers. The bigger granbull grunted and tugged his cock free, starting with the fat knot that came out with a deep and sloppy ‘pop.’ Gordie yelped from this, trembling as his stretched hole was freely leaking out large amounts of musky cum that would need to be cleaned from the floor, more than likely cleaned up by him. 

“Better hope I don’t get stood up tomorrow,” Brandon said as he unceremoniously dropped his brother, letting Gordie fall down onto his unsteady feet. The smaller granbull was still groaning while his hole was still leaking seed. A part of Gordie did hope that his brother could find someone else to pound while another part of him hoped that he would be unsuccessful...
