Silas and Bruce decided to get out of the city for a weekend and had just finished setting up camp in the forest just beyond civilization. Aspen was brought along and he was happy to tag along with them, finding the forest just as comfortable as he did the city. The slight change in temperature was more comfortable for him and he even offered to hunt for the rat and bat. But the two apparently had something else in store for him. Silas offered the feral wolfdog a treat and he eagerly scarfed it down without a second thought. 

“Whoa… What was in that?” Aspen asked as he suddenly felt unsteady on his paws. His body was getting warmer and it was getting harder for him to think. Silas said something to him but it didn’t register. The treat was laced with a special drug and it seemed to be working perfectly. It was meant to induce a sense of heat, as if Aspen was a female at the height of mating season. 

The canine had no idea that the pair of anthros had another reason for being out there. They weren’t just going to camp for the weekend but they were also going to be fucking the wolfdog as much as they could. And with the drug in his system, Aspen would be all too willing to take their cocks. Speaking of which, the panting canine was erect and his tail was lifted, shoving off his winking tailhole. 

“I think he’s ready,” Silas said. Bruce nodded and the two moved in to have the first of what would be many rounds with the talking dog. 

Bruce approached and groped himself through his shorts. He had been looking forward to this trip and refrained from jerking off or hooking up with anyone saying his loads for the event. Chuckling to himself, the large bat stood in front of the canine and he began to pull down his shorts, revealing that he was going commando, showing off the start of his large cock. Silas stepped up to the canine and did the same. In front of the heated dog, the two undressed and presented their erections to him. 

Aspen’s eyes were glued to Bruce’s cock as he jerked and waggled it. “Instead of staring, how about you start sucking on it?” With that being said, he pushed his cock into Aspen’s open mouth and groaned as it was being immediately licked and softly suckled on. Aspen immediately began to moan from the taste and smell of the bat’s length. 

Between the trek out of the camping grounds and the bat’s general lack of proper cleaning over the last few days, Bruce had a strong musk attached to him. It was wafting from his sweaty crotch, immediately catching the canine’s attention. His nose twitched and the sounds of his rapid inhales were heard. The rich scent coming from the winged mammal’s cock and balls kept his attention and combined with the feeling of heat still coursing through him. Wanting that musky prick so badly, Aspen pushed his own muzzle down, making the long and fat shaft disappear in a near instant. 

“Careful, mutt. Can’t blame you for wanting to choke on it but don’t hurt yourself,” Bruce advised. His words weren’t solely out of care, more of him not wanting Aspen to ruin one of his holes before they could really get started. The dog’s heat and need was stronger than he expected it to be. His cock was already down into the hybrid mutt’s throat and the rest was being licked all over by his long and smooth tongue. The sweat was being licked away and Aspen was letting out muffled sounds that made his love for the taste obvious. 

While the wolfdog and bat were having their fun, Silas came in from the other side, getting a good view of the quadruped’s winking hole; Aspen’s tail was wagging back and forth, a sight that made Silas chuckle. But more than that, it made him aroused as well. He approached and closed the distance, getting down on his knees while caressing the half-wild dog’s haunches. Aspen felt this and he stopped wagging his tail, raising it even higher to give access to his back entrance. 

Not wanting to waste time with rimming, Silas instead had a bottle of lube in hand. His pants were already off, leaving him nude from the waist down. The lube was applied to his cock before he simply dropped the bottle, using both hands to keep Aspen steady. Using his hips, the rat got his slippery cock aligned with the hole and then thrust in, gasping from the tightness that immediately surrounded his length. Aspen let out a muffled sound around Bruce’s cock, his body shaking in between the pair of anthros that were penetrating him. 

“That’s what I love about you, boy. Always so fucking tight...” Silas gave his dog some praise before he started pumping his cock into the snug passage, already aiming to slide in as far as he could reach, smacking his pelvis into the quadruped’s rump. With each thrust Aspen could feel his anus stretching out even further around the pistoning length, first his walls were stretched around the girth and then the length was making his depths expand when it was fully inside. A rush of feelings overtook Aspen, even stronger than they would usually be now that he was affected by heat. 

A simple thrust from Silas was enough to send a flash of searing pleasure through him and on the other end, his senses were being engulfed by the taste and smell of musky bat cock. He just couldn’t get enough of it, also wanting it even more than he usually would. It was the only thing he could focus on, continually moaning against the flesh that would be pushed down into his bulging windpipe. While moaning he was also drooling, his saliva leaking down the shaft’s underside and dripping down his own chin. 

It took no time at all for Aspen to be filled from both ends, moaning and having his body rocked from the thrusts coming in from Bruce and Silas at the same time. Both were pushing their cocks in force, wanting to shove their lengths as deep as they could reach. Feeling the pleasure and heat roiling inside of him, Aspen responded to their actions by squeezing his tailhole and roaming his tongue all over, giving both anthros even more pleasure in return. 

Bruce was huffing deeply from the soft and warm muzzle that held his cock. While Aspen was licking all over it, he was free to thrust past the pair of rubbery lips to his leisure. Between the excess of saliva and his own leaking precum that got slathered over every surface, Aspen’s mouth and throat were made into the perfect sleeve to handle his pulsing dick. When he would push it, a small gag sound would come from Aspen but he eagerly handled the erection, feeling it pulsing and squirting pre directly into his stomach. While touching the rest with his tongue, Aspen would also treat himself to the musk coming from the large anthro’s crotch. 

“Good boy...” Bruce praised, rubbing the canine between the ears, giving him some pets as a reward for doing a good job so far. “Just keep licking and working that throat. You’ll get your reward soon...” His other hand joined the first and they got a proper hold on the wolfdog’s head, holding it steady as he elected to thrust even harder, pumping his throbbing and leaking shaft against the tight and slick oral walls. 

“Better take a deep breath!” Bruce growled. He pulled back and slammed his cock back into the canine’s throat. As soon as it was hilted, his crotch pressed firmly to Aspen’s nose and lips, Bruce’s cock began cumming into the passage, feeling the squeezes from the load being gulped down. The throat’s muscles came down on his length, working to milk out even more of his musky seed. Aspen continued to moan from the taste and the heat that was rushing down into his stomach while Bruce was growling deeply from blowing his pent up load. 

On the other end, Silas was still roughly pounding into the wolfdog’s ass, keeping his cock mostly sunk past the spread rim. The lube and his own precum made the hot tunnel incredibly slippery and all too easy to penetrate. Pushing his cock into the absolute limit every time, knocking his body into Aspen’s with enough force to rock him roughly. He wasn’t that far from Bruce, rutting his way into his own orgasm, hissing as he began shooting his sticky ropes into the heated wolfdog’s rump. He kept Aspen close to him as he came, making sure that every drop would be given. 

Stuck in between the pair of cumming anthros, Aspen was shaking hard. Every one of his senses heightened, even the throbs and spurts of seed brought a rush. Knowing that they were unloading inside of him, his extra sensitive nose taking in their musks, it was too much for the wolfdog and he wound up cumming as well, shooting loads onto the ground below him, painting the earth with a series of gooey streaks. 

“Oh fuck...” Bruce groaned as he pulled his cock free and wiped it on the panting dog’s cheek. “Ready to switch?” Silas nodded and pulled out as well. The two were ready to penetrate the other hole but they stopped when nearby bushes were shaking and the heavy sound of footsteps were getting louder and louder. 

Bursting out of the forest was a massive wolf, covered in black fur with ash grey accents. Bruce and Silas were quick to get away, not expecting such a big creature to show up. They left the wolfdog behind, hiding behind a large tree and peaking around it to see what would happen. 

Dark red eyes looked around and focused on Aspen. “Huh... I could have sworn I smelled a female. But...fuck that’s heat alright. I can tell you’re burning up inside.” The large wolf was standing very tall at about 7 feet, making the wolfdog look tiny in comparison. 

“Get down and show me that hole,” the wolf said. Aspen did as he was told, lowering his front half, making his rump rise even higher. “Good... I don’t know how you’re in heat but I got just what you need.” Hanging between the wolf’s hindlegs was a very fat sheath and a pair of balls that were hanging low and swinging with heft. What came out of that sheath wasn’t a pointed canine cock but a blunt and thick equine cock. The tip popped out and the following inches slid from the pouch. Next came the medial ring and more inches followed suit, finally ending with a knot that was of course much larger than Aspen’s. The veins swelled and the shaft swung upwards, smacking into the wolf’s underside as it became fully erect. 

Aspen looked back and gulped as he looked at the unique cock that hung between the much bigger canine’s legs but he didn’t move, keeping himself available and his tail out of the way. The wolf smirked and stepped over Aspen, lowering himself and putting his weight down to keep the much smaller wolf in place. The black wolf’s cock found the tip and pushed in without warning, stuffing that fat cockhead past the rim, making it stretch out even further in an instant. Aspen yelped from him but the sound was all but drowned out by the bigger canine’s deep growl. 

Taking a moment to spread his paws out for better stability, the big wolf pulled back and thrust back in again, showing his strength as his muscles flexed beneath the fur and Aspen was pushed ahead some. 

“Yeah... I can tell you’ve been used already. You stink of two-legger. But you’re still nice and tight for me...” the wolf said, feeling the other canine’s hole squeezing down on his erection, already milking out some of his precum. 

Aspen’s stomach was bulging from the incredible amount of inches that were stuffed into him. The knot was pressed firm to his expanded rim, throbbing against the worn-thin walls, squirting hot precum into the smaller male’s guts. Each thrust came with so much power, leaving Aspen unable to speak. The most he could do was shake and keep himself steady. Every inch was slammed into him, the tip was kept in but the medial ring was always there to pop in and out, bringing a hard shock to the heated wolfdog. His entire body was searing even more, as if his senses were being overwhelmed by the wild wolf’s endowment and force. 

The girth kept itself pressed incredibly close to his walls, he could feel every bulge and contour sliding along. The throbs made him tremble and feeling the pre squirting out brought a rush of added warmth that spread to his entire body. He had to focus on not being knocked about by the thrusts, at least keeping himself steady enough to not be pushed and pulled about. His ass was gripping the unique length so tightly. It was a strain for him while the other wolf was clearly loving it. 

The wolf began thrusting hard and fast, his cock was covered in fluids and could be heard squishing its way in. The beast’s tongue was lolling out, his tail wagging in response to the sensations. His voice was becoming deeper, grunting, growling, and snarling as he relentlessly pounded into the smaller canine, fueled by the persisting smell of heat and the pleasures of Aspen’s gripping tailhole. 

Aspen was a complete mess while pinned beneath the stranger. The thickness overall was making the pleasure strong but what really made him bark and yelp were the even thicker parts such as the medial ring and that blunt tip that was firming up. It was all rolling over his prostate with so much force, giving no mercy to his senses, leaving him shaking and leaking so much precum. It was just too much for him to handle. When the next thrust came, Aspen cried out and came all over again, adding even more of his spunk to the mess already on the ground. 

The black wolf just kept humping away, not even phased by the tighter clenches of the other wolf’s hole. 

Silas and Bruce had been watching all of this. As soon as the large wolf had pounced on Aspen, Silas wanted to go out and help his dog but Bruce advised him against it, instead telling him to watch and see what would happen. They both watched as Aspen was being used and the sight turned Bruce on so much that he got Silas against the tree and pushed his regained erection into the rat’s hole, wasting no time in thrusting deep. With his eyes on the pair of canines, the bat sought to match the pace set by the unique canine, making Silas groan and hiss, his own cock instantly getting hard and leaking from his prostate being bashed again and again. 

The bigger wolf just kept going, pounding as the hole, rubbing his thickness, his medial ring, and his wide cocktip against the clenching surfaces. He continued to push his cock into the deepest point that he could reach, making Aspen’s stomach stretch out in time with the inches sliding in deep. 

The thrusts were getting even faster, the smacks of the cock going in and the thumps of their knot slamming into Aspen’s rump were getting louder as well. With a few more hard pumps and a snarl, the wolf managed to slam his thick knot past the smaller canine’s rim. Aspen didn’t have time to yelp out this time as more weight was put down on him and the bigger wolf was huffing deeply, feeling the entirety of his cock swelling, especially the tip. It was flaring out, stretching Aspen’s ass even further. As the thick and hot ropes of seed were leaving the fat urethra, Aspen could feel his anal passage and stomach being filled up more and more, all of it being kept inside thanks to the thick knot, acting as a plug that wasn’t allowing a single drop to get past. 

Aspen’s stomach was gradually swelling as more and more seed was being pumped into him. The wolf was groaning deeply and even drooling, some of it falling onto him. The lighter furred wolf could do little more than ride it out as he was literally stuck to the bigger one. It wasn’t as if he had the strength to get up and walk away anyhow...

 Bruce saw the wolf reach its limit and knew that it was knotted to Aspen and likely feeling weak from its climax. He saw that as his chance and pulled out of his Silas, leaving the rat behind as he approached the pair of canines. With no fear on his face, the bat strolled right up to the wolf. 

“I knew I smelled another two-legger nearby! This is my bitch and I-” the wolf was cut off when his head was gripped and pushed into the bat’s armpit. It turned out that the two were about the same height. The wolf groaned in disgust against the pit, feeling his muzzle getting sweat from the sweat still dripping from it. He ended up breathing the stink into his sensitive nose and his struggling quickly weakened. 

“That’s right, just keep breathing it in,” Bruce said with a chuckle. “That bitch of yours actually belongs to my friend. I think it's time for me to get a pet of my own and that’s gonna be you.” Bruce called for Silas to get another one of those pills. They had more just in case Aspen’s heat wore off. The rat ducked into the tent and cautiously came in close enough for Bruce to take the pill bottle. He shook a few into his hand. Aspen had only taken two but he would give the black wolf five. He could feel the wolf still sniffing at his pit, doing so willingly now. Bruce stepped away and he was still looking dazed, his nose twitching from the lingering reek of bat musk. 

“First things first...” Bruce said. “Get off of that mutt.” The bigger canine did as he was told, grunting as he eased up. Aspen cringed and dug his claws into the ground until there was a ‘pop’ and ‘splash’ of seed spilling from his gaped hole. Aspen remained where he was, panting heavily from the feeling of his tailhole still leaking heavy amounts of wolf spunk. 

Bruce came in close to the wolf and popped the pills into his own mouth. He then lunged forward, pressing his muzzle to the surprised wolf. He jammed his tongue and the pills into the feral’s mouth, managing to push them down his throat. The black wolf groaned from this, feeling the anthro’s tongue pulling back but still grinding and swirling inside of his mouth. He swallowed the pills and immediately began to feel strange. 

“You can feel it now, can’t you? Hehe, by the time this weekend is over, you’re gonna be my bitch,” Bruce said. “And I think I’ll call you Vincent.” 

Vincent could feel himself becoming more aroused than he already had been but it was different than before, a burning feeling of need that was making him squirm and whimper. He had never felt like this before. For so long he had been a lone wolf, living off the land and prowling for females in heat to dump his seed into. All of this was new to him and he was having trouble processing it all. His cock was throbbing and his head was feeling fuzzy. 

Bruce moved in to kiss him again and Vincent had something to focus on. He found himself kissing the anthro back, moving his own large tongue against the bat’s. Bruce pushed against him, managing to knock him off balance. Vincent fell onto his back and Bruce was quick to get on top, putting his weight down and pressing his wet cock against the beast’s. 

The bat resumed the kissing while also starting to grind his shaft against Vincent’s. Their exposed lengths were frotting together and Vincent immediately began moaning and shaking from the intensified pleasure that came his way. Now fully affected by the pills’ heat, he was at the mercy of his own lust and the bat was taking advantage of that, aiming to break the big wolf down. Bruce could feel the wolf’s lasting resistance slipping away more and more. As their cocks were pulsing together and leaking precum, Vincent’s moans were becoming deeper and more submissive in tone. Feeling that had done enough, Bruce stopped and broke the kiss between them, leaving a thick string of spit between their two muzzles. 

“There. Now if you be a good boy I’ll let you have some fun with my friend,” Bruce offered. 

“Huh?” the rat asked. He was at Aspen’s side, making sure that his dog was okay. 

“I still wanna go at that mutt’s hole. So keep Vincent busy until I’m done,” Bruce said firmly. He stepped away from the large wolf and approached the wolfdog instead. 

“Try not to break him in half,” the bat ordered. Vincent wasn’t used to being told what to do but the offer of a hole – any hole – at this moment was just too good to pass up. So he didn’t talk back and would keep the bat’s words in mind. Once he stood up and came upon the rat, Silas just sighed and turned himself around. 

“This better be worth it...” the rodent groaned, moving his furless tail to the side. 

“Oh, it will be...” Vincent said, the lustful edge to his voice had returned and it sent shivers down Silas’ spine. His body stepped over the anthro’s and the tip of his cock was pressed to the rim. Like before, Vincent pushed in without warning, using nothing more than the lube and the cum that had come from Aspen. It was still a lot for Silas and he was left gasping and shaking from just the tip making its way in. 

Aspen was in a similar position, instead being on the receiving end of Bruce’s cock. He was pinned down by the anthro and felt the leaky tip poking at his still slightly open tailhole. Bruce thankfully decided to ease himself inside slowly. The wolfdog sighed and shuddered as he felt the anthro on top of him. More inches slid into him, filling his hole and touching his depths, but not as much as Vincent’s cock had. It was a bit of a relief to be taking something smaller but his lasting heat demanded stimulation and Bruce’s size was still providing him with that. 

“Don’t get comfortable,” Bruce said firmly. He pulled back and this time he barreled his tip into the dog’s guts, smirking as another pitched bark came from Aspen. The anthro kept pumping his cock in, fast and hard, grunting deeply while keeping the quadruped in place. The only mercy given was that his hole was already stretched, meaning that he was spared the worst of what Bruce would have put him through. There was aggression in the bat’s tone, his growls reverberating in the canine’s ears. Tingles were racing through the dog’s body and the next hard thrust that caused his body to shake hard. “Fuck!” Aspen yelled as he felt his cock throb from the next hard press to his prostate. 

Close by, Silas was huffing as the final inch had been pushed in. As the knot was stuck firm to the outside of his hole, the rest was throbbing against his walls and in his stomach. It had been a strain but the rat managed to take all of the large inches. 

“I can smell that bat on you. That means you’ll handle me well enough!” Vincent began thrusting, rolling his hips without any kind of buildup beforehand. His cock began swabbing at the anthro’s walls, sending jolts of intense feeling through him. Forcing his insides to make room and also making the skin of his stomach stretch around the fat tip, Vincent was already rutting him deeply and harshly, aiming to quell some of his heat and using Silas as nothing more than a means to do so. 

Even though Bruce’s length had done some work in stretching him out beforehand, Vincent’s cock wasn’t any easier to take. The canine was able to consistently pound his equine-shaped flesh in with both speed and power. Each thrust came hard, making his walls spread and a great amount of force applied was applied to his sweet spots as well. The precum leaking out only served Vincent, allowing him to reach in further and thrust in harder as well with greater ease. While Silas was constantly trying to adjust, Vincent was huffing and panting, experiencing nothing short of delight from the warmth and tightness. 

The four males were all making various noises. Silas and Aspen were being thrust into with increasing force. The respective cock inside of them was slamming away into their asses, ending with the bigger male’s body knocking into their rumps, happening all over again as the thrusting continued. From the fat cocks making their way back and forth inside of their passages, the rodent and wolfdog could feel their own cock throbbing and leaking heavily. The constant stimulation of their prostates, the pleasure grew to the point that they were both embracing the pleasure fully. Silas had finally adjusted to the size that kept his hole spread and was even pushing himself back against Vincent’s rump, feeling the knot rough smacking into his rim. Aspen didn’t have enough room to move himself back but Bruce made up for that by thrusting even faster than Vincent was, absolutely reaming the wolfdog’s ass.  

“Taking it you fucking mutt!” Bruce snarled, managing another hard thrust before his climax came. He added his seed to the mess that was already inside of the wolfdog. First Silas’, then Vincent’s, and now his own: the bat’s spunk was flowing into the dog’s guts, making his stomach swell a bit more. Aspen was groaning from the feeling, experiencing the added sense of heat and weight in his stomach. The satisfaction was quelling his heat some but his cock remained throbbing and leaking. When the cock pulled out of him, Aspen was finally allowed to relax, yet again left on the ground, panting and leaking cum from his stretched ass...

Being right to them, the pair simply looked over and watched as Sials was still being roughly fucked by Vincent. The pace of the wolf’s thrusting hard picked up even more and the sounds of his slamming in had become louder as well. Silas was at least keeping himself steady against the series of rapid and strong pushes. Groaning underneath the rocking canine, the rat’s hands were out and pressed firm to the ground, his tail jerking and flicking in time with his prostate being pressed hard. 

“Yes! Yes!!” Vincent yelled out. He was still going while his cocktip flared and the first jets of his seed were ejected with force. More of his sticky and searing seed was released, coming out in the form of huge spurts and all going into Silas’ stomach. Silas could feel every throb and gush, along with his stomach expanding some to make room for the fluid that was being pumped into it. Vincent hadn’t knotted him thankfully, pulling his cock free and squirting the last of his load all over the rat’s rump and back. 

“Looks like it's just me and you,” Bruce said as he stepped up to the large panting wolf. 

Vincent didn’t protest as the bat got behind him, but he did yelp when the bat’s cock was shoved past his tailhole. Bruce started thrusting right away and the big feral’s anal virginity was instantly taken. His introduction to anal penetration were multiple slow yet firm thrusts that were sending jolts through him. The usual sensations were made even stronger thanks to the effect of heat still being felt. 

Bruce’s thrusts slowly gained more speed and the wolf was given more and more. He was panting deeply, his mind reeling and his body seemingly struggling to process everything that was happening. All he knew was that he was being used for the first time in his life, being the one penetrated and not the other way around. This two-legger was breaking him down and it was feeling so good...

The sounds coming from the black wolf had changed; what started as strained grunts had become lustful pants and moans. Even if the feral wouldn’t outright say it, he was clearly loving the treatment and the stimulation of spots that had never been touched before. His hole was squeezing down in time with the thrusts, working out more of his new owner’s precum. All of a sudden he just needed more of this new kind of pleasure. The feeling of the anthro’s cock going deep inside of him, the throbs, the spurts of hot pre, and the smell of musk that was heavy in the air. All of it was making him all too needy for more of the bat’s attention and his cock. 

Another deep thrust from Bruce caused him to bark in a submissive way. His cock jerked and began to shoot fat and sticky ropes that shot across the ground. Vincent was panting heavily from the experience. It wasn’t like his usual climaxes, coming from the steady touching of his prostate. His entire body was tingling and the heat within him was flaring. In that moment he was feeling satisfied yet needy for more. 

Luckily for him, Bruce was still thrusting away inside of him, pumping his cock along the walls that were even more sensitive now. They were also squeezing down, a natural reflex from the canine’s orgasm. Bruce powered through, exerting even more force that kept him deep inside, his body slamming into the other male’s, his heavy balls clapping against the now tame beast’s. It all came to a head when his cock swelled and spilled fat streams of musky bat seed inside of the groaning beast, giving Vincent his very first feeling of being properly bred. His insides continued to knead the bat’s cock, milking out more of his cum. Bruce groaned from this and had a wide smile on his face. Before he was finished, Bruce pulled his cock free and made sure to mark the large canine’s body, making his position over the whimpering feral clear. 

“Now, where were we?” Bruce asked. The plan to spend the weekend with his cock deep inside of a needy mutt was still on but now he and Silas had two instead of one. 

Over the course of the weekend they had countless rounds and when the final day came, Vincent was completely subservient to the large bat, agreeing to follow him home. Aspen was glad to have another canine friend and offered to let him stay at the shack but Silas butt in, explaining there wasn’t enough room for Vincent there. But Bruce put the conversation to rest, revealing that he had enough room for Vincent, that he would be bunking with him, but would have to earn his keep of course...
