“I’m telling you, you’re going to love it,” Aspen said. The wolfdog was walking alongside another canine, a stafford-pitbull mix named Cheevo. While the wolfdog has the common coat, mostly grey with added gradients of white and brown, Cheevo was overly brown with darker spots running along his back and lighter shades on his muzzle and ends of his legs. And unlike him, the mixed breed wasn’t able to speak, at least not able to speak to anthros like Aspen could. He had helped the dog sneak through his owner’s gate and led the way through the alleys, the destination being an abandoned shack that the rat used as a hole away from his actual home. Aspen had recalled how he had gotten close to Silas and he more or less became the street rat’s pet. He was still free to roam the city but now had a place and a person to come back to. He would take shelter in the shack and Silas would come around, keeping him company and making him feel good. Knowing that Cheevo wasn’t given any opportunity to drain his balls, Aspen invited him to come and have some fun with an anthro that would treat him right. 

“It’s just around this corner,” Aspen said, leading the way. They turned, padded down to the end of the alley and squeezed through a gap in a chain link fence, reaching their destination. Aspen had left the rat alone in the shack and hoped that he would still be there when he got back. He didn’t tell Silas what he was going to do, wanting it to be a surprise instead. But the pair of canines were the one surprised when they looked inside of the shack and saw that Silas wasn’t alone. 

Sitting on the salvaged, ragged couch together were Silas and Bruce, a regular customer of his. The bat had come by to replenish his supply of special weed. Its strength was high and it doubled as an aphrodisiac that would get him in the mood right away. Silas was offering a test run and they shared some of the bud. One thing led to another and they were sitting right by side, lacking pants and underwear. Their hands were out and gripping the other’s cock. Silas had a handful of the bat’s girthy dick and Bruce was stroking him in return. 

He looked to Bruce and the bat leaned in even closer to him, pressing his lips to the rodent’s and pushing his tongue in. Silas groaned as he felt the fat muscle sliding in over his own and then down into his throat, making it bulge as it was rubbing and twisting inside of his esophagus. They kept stroking each other off, lust pouring through them thanks to the laced weed and the musk that was rising from them both. 

Using precum and sweat as lube to smooth things along, Silas and Bruce were getting closer to their climax, stroking the other even faster and squeezing tighter. Bruce was the first to reach his limit, groaning deeply as he bucked his hips, cumming hard against the rat’s hand. Silas cupped it against the tip and attempted to catch the thick ropes of seed, moaning as he felt the warmth seeping through his fingers. A few more strokes from Bruce did the trick for him, making him cum and spill his loads onto the floor instead of Bruce’s hand. 

When they were finished, the two released the other’s cock and Silas began to lick up the bat’s seed, running his tongue all over his messy hand. Bruce watched and chuckled, his big ears flicking as he picked up on the light pants coming from the door. 

“Looks like we’ve got company,” Bruce said, bringing attention to Aspen. The wolfdog strolled right in and following behind him was Cheevo, his presence being the surprise that Aspen had hoped it would be. 

“Who is this?” Silas asked as he got a good look at the brown dog. He was just a bit shorter than Aspen but was wider and had more muscle definition. 

“This is Cheevo,” Aspen introduced. He spoke for the other dog and explained why he was brought along. The pair of anthros perked up. Still under the effects of the special plant, the two were still erect and ready for more fun. It had been a while since Bruce got to have some fun with a quadruped and he was very interested in the newcomer canine. 

“Alright, let’s see what he’s made of,” Bruce said. The bat got up from the couch, turning himself around and leaning against it again, presenting his bare ass to the brown dog. 

“Go on,” Aspen said, nudging Cheevo and getting him to walk forwards. Cheevo did so and Bruce spread his legs, the dog came in close enough that his nose was hovering just in front of the musky rim, sniffing at it repeatedly. 

Silas and Aspen were watching, surprised that the large bat was actually offering himself. Cheevo continued to snuff and then his tongue came out, dragging over the winged mammal’s rim. After that first lick, another came and it was followed by another. Cheevo seemed to be a bit nervous at first but he was coming closer and put more effort into swiping his long and thick tongue over the winking pucker again and again. 

“Ooh, good boy…” Bruce moaned. 

“What’s his deal?” Silas asked, referring to Cheevo. “Where did he even come from?” 

“I snuck him out. His owner doesn’t even notice. Poor guy never gets to have any fun. So I figured you could help him out with that,” Aspen answered. 

“Yeah, I can tell he’s all pent up. Mutt’s really going at it,” Bruce groaned. He grunted when the tongue slipped his rim. It was sinking in deep, now swiping directly to his walls, making them just as wet as the outside had been. It was grazing over his prostate and other tender spots, making his cock throb and leak onto the floor as a result. 

Cheevo was just doing what felt natural to him. He was intelligent enough to know that Bruce’s hole wouldn’t take his cock as easily without some kind of lubrication. He had learned a lot about mating with other males thanks to Aspen, the wolfdog sneaking into his yard to offer up his hole. But after a while the wolfdog stopped showing up. The next time he saw him, Aspen was telling him to come meet his new friend. 

But there was two in the shack and one was offering his ass. Licking deeply, Cheevo made sure the passage would be ready for him. While licking away his cock had slid from his sheath. It was even longer than Aspen’s and much thicker as well. Silas noticed as well, his eyes widening as he saw the dark red branch poking out from the dog’s sheath, ended by a knot that was like two golf balls resting side by side. At 10 inches, Cheevo’s cock was as big as Silas’, throbbing and leaking onto the floor. 

After pulling his tongue free, Cheevo was quick to mount the bat. His paws reached out and got a good hold on the anthro. His hips were already bucking, jabbing around until he found his mark. With an even harder shove, he jammed his cock into the large anthro, immediately pushing in as deeply as he could. Bruce felt some strain from his ass being stretched around the fat dogcock but he welcomed it, feeling the rough and rapid humps coming his way. 

Bruce could feel the cock pumping back and forth, precum was freely spurting from it and his body was being rocked by the intensity of the thrusts. Cheevo was panting and drooling as he was going at it, his body smacking into Bruce’s rump over and over. These noises filled the shack, joined by Bruce’s moans as he felt his prostate being rolled over. 

“Yeah, push that cock in deep,” Bruce said. Cheevo responded by pushing in deeper, jamming all of his dick into the bat’s depths again and again. Precum was making his hole warmer and slicker, it was getting easier and easier for him to thrust in. 

Silas looked at Aspen and noticed that his cock was fully out and leaking. He shrugged and got into the same position as Bruce, kneeling next to him against the couch. To his surprise, Aspen was already mounting him, not even taking the time to rim him first. The tip poked him a few times before being pushed in. Silas hissed from his rim being spread around the wolfdog’s girth. He had underestimated the canine’s eagerness to join in on the fun. More than half had been shoved in at once, using nothing more than precum as lube. Luckily the rat was used to having his hole used like this, powering through the ache and letting the wolfdog’s slide the rest of the way in, leaving just the knot pressed against his clenching rim. 

The precum leaking out from Aspen’s cock was making things better for him. The pull back wasn’t as bad in fact he could feel tingles running through his body. Aspen began to rut fast and hard in the same way that Cheevo did. It seemed he was trying to match his friend and maybe even outdo him. 

Cheevo made a sound and Aspen snickered. 

“W-what’s so funny?” Silas managed to ask. 

“He said that your ass feels amazing, Bruce,” Aspen said. 

Bruce snickered as well. From there the pair of anthros were being rutted by the respective canine. The bat was moaning out louder, on the receiving end of a bigger and longer cock. Silas was perfectly happy with taking Aspen, given a rough pounding but it was coming from a canine that already knew what he liked, going the extra mile to thrust in a way that was touching his sweet spots, making his cock jump and leak more precum. 

The smell of sex inside of the shack was getting much stronger, the smell of two guys in need of a wash was added to, now twinged with the smell of heated animals. Cheevo was in need of a bath as well and Silas had never bathed the wolfdog. The speed picked up and the anthros’ holes were clenching down on their pointed cocks, responding to the slaps of the knot and smacks of their swinging balls. 

Cheevo had started sooner so he was the first to reach a more erratic pace, panting hard and moving his hips with all the force that he could muster. The dog’s goal was to spill his seed inside of the bat’s tailhole. Bruce pushed himself back even more, welcoming the wild, unrestrained pounding. 

“Come on! Give it to me!” Bruce growled, feeling the knot being ground against his rim. He was already loving that fat canine cock and he could feel that the bulb was even thicker. Every thrust was an attempt to get it inside and Bruce relaxed his ass as much as he could to let it in, huffing deeply from his rim expanding more and more with every thrust. 

“He’s gonna do it!” Aspen announced. True to his words, the stafford-pitbull pushed hard and managed to lodge his fat knot in, making Bruce groan and dig his claws into the couch’s fabric. The pain of taking it was instantly eased by the spurts of heat. Hot dog cum was spraying in his ass with force, bathing his walls in multiple layers, all being kept inside by the wide pulsing bulb. 

Wanting to do the same, Aspen proceeded to hump away at the rat, slamming his cock in as far as it could reach. Hearing Silas moaning beneath him was sending an extra amount of arousal through him. The rat’s body was being rocked and the dog’s balls were slapping against his own repeatedly, sending an extra jolt through his body. 

Aspen’s pants and moans were turning to growls that were intensifying. Silas was moaning just as much as Bruce had been and he began to work his hole against the pumps, rhythmically squeezing in time with them. Doing this made the canine huff and squirm on top of him, his tail flicking back and forth with more speed. Silas could feel drool dripping down onto his neck. He knew that the wolfdog was close, not just because of that but also because of the hard throbs being felt from deep inside of him. 

Another hard thrust came and the knot was rammed in, making Silas shudder and wince. His hole clenched down even harder, making Aspen’s climax even stronger than it would have been. The half-wolf howled out as he came inside of the rat, releasing thick amounts of cum that had been stored up over time. Aspen’s tongue came lolling out as he rode out the bliss. Cheevo was still doing the same alongside him. Their balls were drawn up and pumping loads through their knotted cock, all being released inside of the respective anthro. 

Eventually their cocks softened enough that their knots came free. Cheevo was panting and his tail was wagging. 

“See, I told you. These guys know how to treat a dog right,” Aspen said. 

“And speaking of that,” Bruce said, getting their attention. He was back on his feet, not fazed by the cum leaking out of him. “Now it's my turn. Time for you to experience it from the other end.” The bat didn’t wait for Cheevo to prepare himself, grabbing him and hiking his tail up. 

Bruce spit on his cock and stroked it, coaxing some precum out and smacking the tip to the dog’s hole. He then pushed, making the canine’s hole expand around his rim. Cheevo yelped from the much bigger male taking his anal virginity. Bruce groaned from the tightness and pushed the rest of his big cock in, making the dog’s stomach bulge some. 

“Ooh yeah…” Bruce growled, giving a firm smack to the dog’s side. “Gotta love breaking them in.” 

Bruce began to thrust in with a quickness, powering through the quadruped’s thickness. Cheevo had been whimpering at first but they soon ceased and he was back to panting, spreading his hindlegs and keeping his tail hiked up as the thick uncut meat was steamrolling back and forth, grinding against his previously untouched walls, leaving behind precum that was leaking and clinging to the surfaces. It started out as a few dribbles that became thicker and fuller spurts of pre that were rushing out from the throbbing bat cock. It provided lube that allowed his cock to slide in even deeper, making a deep squelch with every thrust. Bruce was breathing heavily using the snug hole and Cheevo’s cock had gotten erect again, throbbing and leaking even more onto the already marked flooring. 

Aspen was distracted and that allowed Silas to all but pounce on him. The wolfdog was on his back, looking up at the anthro. Silas got on top of him, easing his body down to the point that their front sides were touching and their faces were aligned. Silas reached a hand down and used it to guide his cock to the canine’s tailhole before pushing it in, making them both groan. Aspen had missed the feeling of the rat’s cock sliding into him. Cum was still clinging to the flesh and that helped things along.

As soon as he was fully inside, Silas began to thrust into him, pulling back with his hips and then pushing in again, making his cock slide into the end of the dog’s anal passage. Doing this made the dog snarl, pleasure coursing through him. Aspen’s hole was gripping his shaft so tightly and pushing through that tightness was sending waves through the rat, keeping him panting and shaking. 

With the anthro on top and the dog beneath him, lying on his back, Silas had Aspen in the mating press position and was using gravity to pump all of his inches in, feeling them getting slicker as more of his precum was leaking out and being smeared. When he pushed in, his heavy balls smacked into Aspen's, adding another element to their fun. The shaft never fully pulled out, at least half of it being kept past the spread rim. 

“Oh Silas!” Aspen moaned, his tongue lolling from the constant filling of his hole. 

“Don’t get too comfortable,” the anthro rodent said. He had gotten himself into the groove, finding the perfect rhythm and kept at it. But now he was going even faster and harder, using his weight to keep his cock in deep. Aspen’s body was being rocked against the floor and the rat’s chest was grinding against his own. His unsheathed cock was bouncing back and forth, moved about by the force of the incoming thrusts. Their connecting crotches produced a firm ‘smack’ sound. 

Silas had his hands planted firmly to the shack’s floor, giving himself extra leverage to thrust with, this allowed him to plow the dog’s ass even harder, making their shared moans louder as a result. The squeezes were getting tighter as Aspen’s prostate was being touched again and again. 

“Fuck this dog’s ass is good!” Bruce said as he shoved his way back into Cheevo’s guts. His cock throbbed heavily against the dog’s walls, releasing more precum that oozed into the mixed breed’s deepest parts. 

The bat continued thrusting against the tightness, pumping in faster now. The sounds of his cock being tugged out and pushed back in were easily heard along with Cheevo’s heavy pants and pleasured whines. The squeezes continued, natural reactions to his prostate being touched and pressed hard over and over again. Cheevo had his paws firmly pressed to the floor and yet his body was being rocked by the force and by the bat’s balls coming in to knock into his own. 

“Urgh! Fuck!” Bruce snarled as he thrust in hard again, slamming all of his cock inside and keeping it there. A rush of pleasure overtook him as he came. Another whine came from Cheevo in reaction to the first blast of hot and thick bat cum. So much of it was rushing from the large anthro’s cock that it was making the dog’s stomach swell. Bruce kept his cock in deep, making sure that Cheevo was taking every gush and drop of his musky spunk. He could feel it rushing from his heavy balls, racing through his shaft and splattering all over the dog’s still-snug anal walls. 

Sighing deeply, the bat tugged his cock free and there was a gush of cum spilling from the dog’s stretched tailhole. Cheevo was still panting as he cum was leaking from his own cock. Bruce hadn’t even noticed that the dog had cum, he just chuckled as he watched Cheevo release the last of his load. And then he watched Silas and Aspen finish up. 

Silas had been humping into Aspen the entire time and the wolfdog had reached his limit, yelping and squirming beneath the thrusting rat as he began shooting ropes onto himself and onto Silas as well. Feeling the seed mark his own pelt served to excite Silas further. His hole began clenching down hard and Silas used that to propel himself towards his climax. 

He thrust in one more time, burying his shaft in deep and blowing his second load directly into the half-wolf. His fat balls were pumping large amounts of cum into Aspen, filling up his ass and coming back to splash around his cock, surrounding it in warmth and heat. It was making the feeling of his orgasm even better and so was the continued squeezes of the wolfdog’s anus. They were milking even more out of his balls, giving Aspen a belly full of his spunk. When he was done he all but collapsed on top of Aspen, feeling a bit weak from how hard he had cum. 

Aspen and Cheevo stuck around for a few more rounds but as sunset was approaching, they took their leave. Aspen had to get Cheevo back home. It was almost dinnertime for the stafford-pitbull and his owner would finally realize that he had been gone for hours. Speaking for him, Aspen confirmed that Cheevo had a good time, and promised to bring him around again soon. Silas and Bruce were happy to hear that. Bruce felt it was time to leave as well. He paid for the weed and thanked Silas for the test run and the unexpected good time that came along with it. 

“Here’s hoping those mutts drop by the next time we meet up,” Bruce said with a chuckle as he left the shack. Silas stayed behind, stretching and breathing in the lingering smells of musk and sex. The setting of the sun just meant that there was a whole night life for him to take advantage of. He could make some rounds and return to the shack where Aspen would likely be, perhaps he could get in another round before finally settling down for bed…
