Things had changed a lot in the underground rat's tribe. It started with the siege on the village that Fen had come from. His presence had inspired the other rats to bring back more surface-dwellers and claim that as mates. The large rodents were instantly taken with them. Their smaller bodies kept them so tight and the sounds they made were so arousing. There had been enough villagers for every rat in the tribe. Even those already paired with a fellow tribesmember had a "pet" by their side to take care of their needs when their partner was unavailable.

At first the villagers from the small town above were scared out of their wits. Large rats had stormed their town and snatched them up. They were locked in a cage on wheels and tugged through the various environments of the underground. When the rat's tribe was reached they were finally released but weren't free. The large hands of various rodents snatched them up and wasted no time having their way with them. At first the ordinary villagers resisted but in time they grew to love their new rat partners. With such large bodies that had hefty cocks and plump balls attached to them. Their scents and the manner in which they were handled. The pleasure was intense for them and it wasn't long before they couldn't get enough. The villagers had made no attempts to escape and had become a part of the tribe permanently.

As they acclimated to life underground, the former surface-dwellers couldn't help but ponder how the tribe had such a healthy population when each and every one of them was clearly a male. That question was answered for them soon enough when many of them wound up pregnant despite themselves being males as well. Learning the rat's language allowed them to hear it from the rodents' mouths. They were indeed able to impregnate just about anyone regardless of species or gender.

Time passed and a new generation of ratmen came along. In addition to the regular big strong rats their kind were known for, there were new kinds of rats born alongside them. Being hybrids of underground rats and surface dwelling anthros, these new rats grew up to be smaller. Their adult height was just a bit taller than most villagers and that made them much smaller than the ones born from two tribe rodents. But in exchange for that smaller size these hybrids were blessed with higher intelligence and greater endowment that managed to even outdo what the bigger rats packed.

The two kinds of rats were given terms to distinguish them. Under-rats were those who came from two rats from the underground tribe while Surface-rats was the term for those clearly born from a villager. They grew up alongside each other and though they were clearly different, the two subspecies were given the equal amount of respect. As the first generation had come of age they proved themselves to be just as useful. Surface-rat's smaller size allowed them to fit into spaces that the other subspecies could not. They were faster on their feet, having higher agility and their higher intelligence gave way to problem solving. They used the environment around them to complete tasks such as creating simple tools or even fashioning traps. While multiple under-rats in a group provided great strength and many surface-rats putting their heads together led to impressive creations, it was found that an under-rat and surface-rat together was the optimal pairing. Their strengths and weaknesses complimented each other in a fight and a surface-rat guiding an under-rat during tasks led to the job getting done faster and efficiently. This let to a period of group where the tribe expanded and its people flourished...

***

Sven the surface-rat had quite the reputation about him. He was known as a slut in the tribe and those who approached him would soon know why. It was easy for him to charm others, having coal black fur, a fit athletic form, and of course a cock that was even bigger than many under-rat's. He was one that proved that being smaller didn't mean that he was any less of a good lay. Being not picky at all, Sven allured just about anyone he could, be they fellow rodents or former surface-dwellers. His favorite thing was to be on top, slamming his hefty cock into a hole and hearing the moans of his partner. He wasn't opposed to bottoming but only chose to do so for those he felt were worthy...

Sven had a job in the tribe as a digger. He would accompany others to a nearby mine where they would dig up various stones. His favorites were the kinds that glowed. They had been only known to be growing from way up above, sprouting from the earth-sky in an upside down manner. Through some mysterious means they provided light to the world below the surface. It was a surprise when they came upon these stones in the mine. They had the familiar glow but in a weaker form as they were much smaller. These were mined and used to provide light where the glowing crystal's glow couldn't reach. They were also used for accessories. It was found that these glowing stones came in various colors and the tribe leader was made a crown with the stones embedded in it. They were all pure and flawless, polishing and shaped from only the shiniest and clearest of the glowing rocks.

The others used them as well for various means but Sven liked to use them as an accessory as well. When he was younger, the rat had two white glowing stone pieces attached to his ears when they were pierced. Being a digger, he was allowed to keep the small chunks that couldn't be used. So he polished and shaped them himself and put them to good use. The surface-rat had soon showed off his cock, the underside having multiple piercings with green stones that were arrayed in a visually pleasing manner, running down from just behind his tip to just before the end of his shaft. Not only had it drawn even more attention to his dick but the stones' glow made the veins along his cock glow as well. Maybe it was just a placebo effect, but Sven felt that his virility had increased since he got his cock pierced. He came more when jerking himself off or when penetrating someone and he had an easier time attracting other males. His favorite method was using his own pheromones. Though he was smaller, his body smelled just as strongly as any under-rat.

After testing out his new capacity and limits, Sven felt it was time. He was experienced in both giving and receiving pleasure. His libido and virility had never been higher. It was his hope that these factors would make him a good partner. Some rats wanted to be good fighters or hunters or even diggers. Mastering one's craft, especially one that could benefit the tribe as a whole, was a great virtue for their kind. But Sven's desire was to find a mate. But they had to be special. Someone who could keep up with him sexually but also give him the comfort and sensuality that he desired. As far as rat's were concerned he was very young, still not that far from the age where adulthood began. Even for their kind it was early for them to find a life partner but Sven was determined to find one right away.

Sven was being rather picky about who would be his partner. It was a choice that he was taking seriously. There was no shortage of attractive rats both big and small but none really struck Sven as someone he wanted to spend his life with, someone he could dedicate himself to and gain endless satisfaction from them doing the same.

There was a celebration held within the tribe and Sven decided to attend. When night came, signified by the crystals embedded in the earth-sky growing dim until their glow ceased entirely, the tribe was gathered around a large bonfire that had been lit. Music began to play from drums being rhythmically struck and in came rats that were completely nude and adorned with paints that decorated their pelts and glowing stones that brought further attention to them. Along with the music and entertainment, there was also plenty of food brought in for the attendants to partake in.

The hunters brought in more than usual so everyone could get their fill. Sven had his own portion but he was sitting away from everyone else. He was mostly observing the celebration, still searching for a possible suitor. Rats of various sizes, shapes, and colors were all there observed by the surface-rat but the ones that really caught his eye was a group of big under-rats that had congregated together. They were all talking to each other while feasting on meat, unaware of the surface-rat that was drifting back and forth between them.

The under-rats were all in the nude, showing off their own strength and virility in a casual manner. As they moved about their junks swayed and bounced, catching the eyes of others who passed by them. Sven too gazed upon their fat cocks and balls, noticing how they hung with visible weight. Under-rats tended to thicker when it came to penis size while surface-rats were usually longer. Sven couldn't deny that he had a thing for under-rats, their size and strength never failed to send shivers down his spine.

He watched as another surface-rat, a thin ash furred one came up and began to speak to the group of burly rodents. They talked for a bit and one of them broke away from the group and followed the smaller rat off. A ceremony like this provided the perfect opportunity to mingle. Pairing up was encouraged as the growing tribe were going to need more to support their expanding reach. Their kind typically needed to be bred over the course of multiple days for the seed to really take but with some already being drunk Sven felt it was certain that a few of these attendants would be walking about with swollen bellies in a few weeks.

Another surface rat approached, this one being brown in color with white patches here and there. His figure was curvy and a bit wide in the hips. The feminine form was considered exotic among their kind and he clearly had no issue getting the under-rats' attention. The brown rat appeared to ask them something and just like that the bigger males were arguing with each other.

It was obvious that they were arguing and now fighting over who would be the one to spend the night with this alluring rodent. Sven was actually feeling rather jealous. He wished it was him they were fighting each other. The cluster of large rats broke up as two in particular became locked in a scrap that was more than just simple chest-thumping. Sven perked up as the two began wrestling with each other. Others began cheering them on while the brown furred rat watched with a smirk on his face, being well aware of the hold he had over the horny and drunk under-rats.

Sven took a good look at the fighting rats and noticed that one of them was bigger than the other. His deep voice reached Sven's ears and the black rat felt his heart beating a bit harder than before. The two continued to fight until the brown rat raised his voice and called for them to break up. When they did separate, Sven was able to see that the bigger rat had white fur with a pink scar running along one of his shoulders. He was even bigger than the other under-rat. In fact he was bigger than the others, a goliath that stood out when the dense huddle was broken up.

The brown rat looked back and forth between the bigger white rat and the smaller stone gray furred one. He chose the gray rat and left the goliath rodent behind, much to Sven's shock. He stood up and then realized that his loincloth was tented from his erection. For a moment he hesitated but then saw the disappointed look on the other rat's face and felt compelled to approach.

"Hey," he said.

"...Hey..." the bigger rodent said.

"You're a good fighter," Sven complimented. The white furred rat perked up and smiled a bit while thanking him. "I can't believe he didn't choose you."

"It's cause I'm too big," the under-rat groaned. From his tone and look it could be assumed that this was an outcome he was used to.

"Too big? That's ridiculous. More like they can't handle you," Sven said. The under-rat's smile widened and Sven felt his heart skip a beat.

"Come with me," the surface-rat said. He took hold of the bigger rat's hand and began guiding him away.

"W-where are we going?"

"I say you won that fight. And you deserve a reward for it." Sven guided him away and the other under-rats called and chuckled, knowing that their friend was about to have some fun.

They left the celebration behind and were shrouded in the shadows of dense overgrowth. Their night vision and glowing of the white rat's glowing stone necklace provided allowed them to still see just fine.

"Do you have a name?" Sven asked as he looked up at the under-rat again.

"Drova."

"I like the sound of that. You can call me, Sven."

"I like that name too," Drova said with a tone that nearly made the black rat swoon. Despite his size and the ferocious way he fought, the bigger rodent was clearly the softer type. The way he spoke and carried himself suggested a comforting gentleness but Sven had already seen what this beast was also capable of.

"Do you have a mate, Drova?" Sven asked, his voice taking on a suggestive tone.

"N-no. I'm pretty unlucky when it comes to that kind of stuff," Drova said with a soft blush.

"How so?"

"I... I really like surface-rats but I think they're scared of me. They must think I'm gonna tear them apart or something," Drova said.

"That sounds exciting to me. And it just so happens that I'm looking for a big and strong under-rat..." Sven said. He reached out and pressed his hands to the bigger rodent's soft belly. Drova's musclegut form was turning him on so much and getting in closer allowed him to take in the under-rat's musk. It was so potent as Drova was still sweating from the fight.

"So does that mean..?" Drova dared to ask.

"I think we can give each other what we need," Sven confirmed. "Now... About that prize."

"R-right. Can I see..." Drova touched his large hand to Sven's slightly tented loincloth. There was a faint glow against the fabric and he was clearly curious. With a smirk, the surface-rat pulled the cloth to the side and showed off his lengthy and girthy cock. The glow was brighter from the stone being unobscured. In the darkness his entire length had a green glow to it, making it appear as if it was some kind of magical artifact.

Drova couldn't help but gasp, completely enthralled by the sight. He got down on his knees and leaned in to get a better look. Decorating one's body with stones was a common practice but he had never seen piercings like this, arranged in a ladder formation that made just about every inch radiate the lush color of green.

For just a bit longer, Drova gazed upon the large cock and heavy balls. Right after that he suddenly reached his hand out to gently rub and caress the sack. They felt so warm in his hands and also damp with sweat that began to wet his palm. His touch was gentle and the circular motions of his rubbing caused Sven to huff in response. Having his muzzle so close, Drova could easily smell the other male's musk and it was making his mouth water. While teasing the other rat's ballsack with greater speed and care, Drova also began taking in the smell they produced.

The more he sniffed, the more allured and aroused Drova became. He was being affected by Sven's potent pheromones. By drinking in the surface-rat's musk, the bigger rodent became all the more needy. This urge to give the other male pleasure came over him, being too strong to ignore. It wasn't as if he didn't want to interact with Sven in this way; to play with his balls and lavish that massive cock... Now it was all the harder for him to resist.

It ended up being a battle that Drova quickly lost. He couldn't help but pressed his nose right where the smaller rat's cock and balls met. The smell was twice as strong now that it was coming directly from its source. Every whiff sent that intoxicating aroma directly into the deepest parts of his nose. He closed his eyes and hummed deeply.

Another huff came from Sven from above. He felt the puffs of warm breath against his loins. Drova moving his muzzle a bit still sent tingles through his junk. It was enough to make his semi-hard twitch as it began to become more rigid. It swelled further and its weight led to the flesh sitting directly over Drova's muzzle. The smells of pheromones, sweat, and musk all blended together when Sven reached full mast. Drova began to directly rub his muzzle against the hard cock and hummed as he marked his own white pelt with the odor. Just like his paw it was becoming wet and the delightfully smelly scent was already clinging to his facial fur. He could feel the heat and weight on his face and it was making him melt along with the continual odor that poured into his nose.

"You like that, don't you?" Sven asked. He was loving the attention that was being given to him. The sight of such a large rat down on his knees and getting off his cock smell was so hot. As great as it was, the surface-rat was wanting more than just some sniffs and made that clear by pulling his cock back and pressing the tip to Drova's lips.

The cock's tip was leaking and a thick glaze of precum had gotten onto Drova's nose. The under-rat lapped it up and then took it upon himself to put his hands to good use. He took hold of the cock in his hand and noted that its size was nearly too much for his own larger hand to wrap around. Stroking back and forth was fairly easy thanks to the sheen of sweat and the precum that quickly lubricated his rough hand. It slid all the way down to the balls before coming back up to give the tip a squeeze.

While pumping at the other rat's length Drova couldn't help but flick his tongue along the leaking tip. He slid his hand upwards and tugged the foreskin along. At the same time his tongue came darting out to slip underneath the flesh covering. Sliding his tongue between the folds he again hummed from the extra strong that met his taste buds. They were both making sounds in reaction to the enjoyment they were both experiencing. A thick line of precum came from the tip and it landed directly on the under-rat's tongue. The heady taste struck his senses and paired perfectly with the strong scent that persisted. He kept his mouth open to receive another thick rope of precum. It was gulped down and Drova panted, his tongue lolling as he sped up the pace of the jerking, wanting more from the other rodent. The squeezes to the base and tip were a bit stronger too and this rewarded him with more of what he wanted.

Sven proved that his balls had plenty to give. Drova had caught as much as he could but his muzzle fur became weighed down by a glaze of precum that shot out onto it. The more they did, the more that Sven was falling for the under-rat. He was certain of it now, that this was the male he wanted to spend his life with. Another thing that was certain was his own need for more. Drova blinked from the hand that placed itself up on his head. Sven pushed the under-rat's head down and thrust in at the same time, shoving his cock into Drova's mouth and even into his throat as well.

Drova had been completely caught off guard by this and when looking upward he was treated to the sight of Sven smirking. The smaller black furred rat was still rocking his hips, grinding his cock against that soft and hot tongue. Drova quickly embraced this and moaned as he felt the piercings rubbing over his tongue as well. While having his mouth filled, the large white rat was also treated to the unfiltered musk that came from Sven's crotch pressing itself close to his sniffing nose. He did his best to relax his throat so the hefty shaft could slide right in.

Sven reached another hand down and they were both taking hold of Drova's head. The simply and slow paced motions turned into full on face-fucking in an instant. Rolling his hips faster brought him more pleasure, especially when his cock slid down into the hot and squeezing hold of the bigger rodent's windpipe. Thick gushes of precum were being directly spurt from the tip and gulped down without hesitation.

Just as Drova was starting to get into it, the cock was pulled from his mouth and sat upon his muzzle again. Ropes of spittle and precum were flung about, making the bigger rat's face even messier than it already was.

"Tell me how much you love it and I'll let you finish," Sven said, his voice having a devious edge to it. He knew the other rodent wanted this so badly and he could indeed hear Drova whimpering for it.

"Please let me suck on your big musky cock! I need it so bad!" Drova pleaded.

"Good boy..." Sven praised as he pushed his cock back in. He shoved directly into the throat and Drova gagged around but quickly regained his composure. As best he could, the white rat sucked and licked against the mouth fucking and hummed from the splashes of hot precum that were gulped down. The heat traveled down his esophagus and joined the rest that was already in his stomach. So much had been drunk down so far and wet he wanted even more...

Digging his claws into the earth for better leverage, the smaller rat began pounding his cock into the sucking mouth and squeezing throat. He pushed all of his inches inside each time, pressing his balls firm to the other rodent's chin. More of his precum was being fed to Drova and the feeling of him swallowing around his cock made him groan with greater volume. Luckily their voices were drowned out by the celebration's various noises.

Being the bigger male, Drova was more than durable enough to handle it all and felt that having his throat pounded was a fair exchange for being able to smell more of that crotch musk from its source. The throbs in his windpipe were even stronger and he assumed that Sven was nearly ready to blow his load. That didn't stop the other rat from slamming himself in deep. In fact, the black rodent made a point to speed up even more.

"Ough! H-here it comes..!" That added speed had pushed Sven over the edge and there was no going back now.

Sven's deep moan reached Drova's ears and his cock pulsed harder against the bigger male's lips. Sven managed to thrust in one last time before he came hard. He blew his load directly into the throat that was swallowing around his cock. So much of his musky seed was shooting out, being so hot and thick. Drova moaned deeply from it and did his best to make sure he didn't spill a drop of it. The fat ropes coated his mouth and throat. Even after gulping it down he could feel the seed clinging to his oral walls. Sven continued to voice his bliss as he pulled his cock free. It shot one last thick rope over the other rat's face. They were both left panting for their own reasons and spent a moment just looking at each other.

"Ready for more?" Sven then asked. Drova was surprised by this but then noticed that the surface-rat's cock was still hard.

He nodded and Sven chuckled. Having control over the situation, he guided Drova into a new position. The bigger rodent was turned around and lying on his stomach. His large and soft looking ass was in full view and open for the surface-rat to interact with. Sven couldn't help but reach out and take hold of it. He planted his hands on the fat ass and gave both cheeks a firm squeeze. Drova reacted with a groan. The under-rat never had his ass played with before. Sven's handling was rough but he was slowly getting used to the feeling and was starting to gain some added arousal. Those smaller hands rubbing and tracing along the curvature of his rump was rather exciting, especially when those fingers slowly slid towards his hole.

Drova's expectation was to be teased further but his cheeks were pulled apart without warning. Sven grinned as he gazed upon the other rat's exposed tailhole. There was hardly any time afforded for Drova to adjust: as soon as his rump was spread a moan was then forced out of him. Sven had plunged his muzzle in between the thick asscheeks and pressed his tongue directly to the twitching pucker. He began licking at it, dragging his tongue over the opening in a rough manner. While doing that he was drinking in the raw musk that came radiating from the bigger rat's hole. The space was hot and its sweat was clinging to his lips as he slid the muscle further along the muscle. He moaned directly against the rim. Drova felt this and moaned as well from the shiver that ran up his spine.

Sven gradually put more effort into his actions. His tongue was twirling all over the rim while his hands rubbed and groped the other rodent's ass with greater strength. Doing this coaxed more noises out of Drova. Going back and forth, their actions and moans fueled each other's ever growing lust.

"Please. Push it in," Drova moaned. His large tail flicked and his hands were dragging against the soft earth. Having his ass licked felt so good but he knew there was more to come. All of this teasing was making him impatient as well.

Sven was surprised but he chuckled and agreed. Upon finding the center, Sven began pushing his tongue in. It was done roughly and with a quickness. Right after being shoved inside, the surface-rat began flicking his tongue about, rubbing the soft and musky walls with it. He moaned from the taste but Drova was moaning out even louder. Sven reached in even deeper, seeking more of the strong natural flavors of the under-rat's anus.

"Oooah! Rrgh..!" Drova had his large fists balled and pressed firm to the soft earth. He was grateful for the overgrowth that hid them. The noises that came from him weren't the kind he usually made. Not deep and dominant but breathy and slightly pitched. While he felt embarrassed, Sven was clearly loving these noises. He could feel his ass being reamed with increasing power. That tongue was grinding and twirling in a way that forced more noises out of him. He would groan and jump from certain spots being touched and his own fat cock was throbbing against his soft and warm belly, making a mess of his own fur.

Sven was focused on nothing else but the other rat's big, delightfully smelly ass. His eating out was so intense that it was easily heard. His own muffled moans, deep licks, slurps, and sucks. Anything he could do to the rim and passage, Sven did so. All the while his nostrils were flaring, endlessly drinking in the direct scent of a rat rump that was overdo for a wash. Despite what he had done so far, Sven wanted even more and allowed himself that by pushing his tongue in even deeper, shoving it as far as it could possibly reach. From there he was licking with more power and moving his tongue about with purpose, feeling around until he found the spot he was looking for.

Sven purposely gave a series of hard licks to Drova's prostate. Doing so kept the under-rat moaning out and squirming. Sven knew that he wouldn't be able to endure this for much longer and was actually looking forward to what would soon happen. And just as he predicted, a particularly louder and longer moan came from Drova. Pulsing hard against his belly, the under-rat's cock shot out thick ropes with force. Gush after gush of rodent spunk led to his stomach and the earth he laid upon becoming messier and messier.

From his climax, Drova's tailhole was clenching down hard on Sven's still moving tongue. These actions were making the bigger rat cum harder and for longer than he usually would. The surface-rat was basking in it all: the sounds, smells, and taste that all remained so strong and exciting.

When his orgasm had finally come to an end Drova was left panting and shuddering. Pleasure continued to course through him and it wasn't just because of the tongue that was still moving around inside of him. Another groan and gasp came as the wet thing was finally pulled out and his hole was left to wink from the empty feeling.

"How was that?" Sven asked, wiping the drool from his lips.

"That was... Can we do it again?" Drova asked. Like Sven had he bounced back. His cock was still hard and that sense of need had come over him again, being too strong to ignore.

"I can do you one better," Sven promised. He stood up while the bigger rat remained in his current position. Drova was so big that he needed to climb on top just to actually do what he intended. When he got up there Sven clutched the other rodent's thick tail while already pushing his cock in between the soft and thick cheeks. Using just his hips, he slowly pressed until his cocktip made contact with the freshly rimmed opening.

Thanks to that rimming it was easy to further spread Drova's rim and slide his cock in. The bigger and smaller rats both moaned out together. That large cock that was bigger than his own had forced Drova's to stretch further and the sensation of being filled came immediately. And that feeling grew even more intense as more inches came sliding in. Sven was instantly taken with the tightness that persisted. The under-rat's ass proved to be perfect when it came to taking his large endowment. With a simple push forward all of his cock was jammed in and his plump balls were pressed snug to the fat ass.

Sven started rocking his hips slowly just for the sake of not overwhelming the bigger rat. He was well aware of how big his cock was and it was a lot for one to handle. To Drova's credit, he was taking the length very well. More of those moans were coming from the white. His walls were being rubbed by the lengthy and thick erection. It had no trouble touching his sweet spots like the tongue had and his prostate was given full stimulation, rolled over completely with each back and forth. Those piercings brought extra pleasure as well, providing a unique sensation that couldn't be ignored.

Sven shoved himself in balls deep each time. His inches slid into the even tighter parts of Drova's ass and he held that position for a few seconds, letting himself be squeezed before he resumed. While not as direct, the smell that wafted from Drova's body was still potent and Sven breathed it in via long inhales. The scent and feeling came together and served as confirmation: Drova was the perfect partner. Soft, kind, musky, and huge. Now it was just a matter of claiming him.

"Ready for more?" Sven asked while licking his lips. He could feel his dick throbbing against the walls and dripping as well. He was still rocking his hips in a smooth manner and the slick fluid was being smeared along the hot surfaces.

"Yes! G-give it to me!" Drova said, being just short of pleading.

Svan passed up the chance to have his ego stroked again, preferring to stroke his dick with the under-rat's ass instead. He pulled back and jammed all of it back inside with an unexpected amount of strength. Right after that he elected to start thrusting in rapidly. His hips were rocking fast and the sounds of his balls slapping against Drova's ass joined their moans.

Drova felt his own cock pulsing as his body was being rocked back and forth in time with Sven's humping. Each thrust brought that fat cock into his deepest parts. Hot precum washed over his walls and made them easier to slide against. His prostate was struck even harder than before and that caused him to make more noise. From this spot being touched in this way, Drova's tailhole clenched down Sven's ass in a stronger way. They were giving each other greater amounts of pleasure, one act fueling the other in a perpetual cycle.

Sven groaned from the hold that was still tight around his cock and touching that special spot within Drova led to the tightness increasing. He was still inhaling the deep heady smell of the under-rat's musk. It seemed to be stronger now and easier to pick up. They were both sweating from their respective efforts and that was making Drova's natural musk all the stronger. Humping hard against them led to the smack of his sweaty balls bashing into Drova's ass. The bigger rat enjoyed these strong thrusts that filled his ass better than anyone else had so far. He was also drinking in musk, never tiring of the pheromone-laced scent that was being constantly produced from Sven's sweaty body.

"Fuck, you're ass is perfect!" Sven praised as he let go of the tail and clung to Drova's body. Having the soft, warm, and damp pelt pressed against his own, the surface-rat began pumping his cock in even faster and that led to the volume of their sex increasing.

The surface-rat was holding nothing back now, pummeling his inches into the tightness that persisted. His own precum made it so easy for him to thrust in as deeply as he could reach. Both had raised their voices even more, not caring if they were heard by those still attending the celebration. They were both lost in the raw pleasure and scents that reached their noses.

Drova could feel his climax approaching with every thrust that came. His breathing became heavier and he was actively trying to keep himself together but it was a losing battle. After a few more strikes given to his prostate he lost that hold and bellowed from the rush of his climax. Sven couldn't see it from his position but he could certainly feel the extra hard clenches. Drova was groaning and shaking as he came again, this time even harder than before. More spurts of hot stickiness were unloaded and began to coat his stomach even more. While he drained his balls of their supply, Sven thrust in hard for a final time and began marking his new partner with thick ropes of his own hot and musky seed. Drova continued moaning as he felt himself being pumped full just after shooting his own large load. Sven kept himself in deep inside until his climax had come to an end. He pulled down and jumped down, leaving Drova to groan as cum began to leak out of him.

"That was perfect. You're perfect in every way. Just what I've been looking for," Sven said.

"What do you mean?" Drova asked, still dazed and panting.

"I'm looking for a mate and I just found one," Sven said as he strolled around to kiss the still lying under-rat. Drova embraced and then returned the kiss. The two moaned against each other as they let passion and the beginnings of a romance envelope them...

***

Svan and Drova had become an official item since then. They were incredibly close and made their pairing no secret within the tribe. Many were sad to see that Sven had been snatched up by someone else; others were surprised to see the lithe rat at the much larger-than-average under-rat's side. The two proved to be a perfect match with each other. Sven's unbridled confidence contrasted Drova's own nature. He was strong and aggressive when he needed to be but in the company of his mate, the large rodent was allowed to be himself.

Sven had finished his duties as a digger for the day and had brought back more stones for his collection. The wait for his mate wasn't long. Drova's weight served to announce his arrival in the form of heavy thumps that grew all the closer until the white furred rodent came in from the large opening of their hut. In fact everything was a bit oversized so Drova wouldn't be uncomfortable or have to limit himself. The bigger rodent had come back with fruits for them and smiled warmly when he saw his mate.

Sven approached him. Drova put the fruit basket down and closed the distance between them. When they were close enough they began kissing as a way to welcome each other. Though the under-rat was bigger, Sven was the more dominant one in their relationship. They treated each other as equals but Drova had no qualms with being ordered around and made to serve his partner. But there were times when the roles were reversed, when Sven wanted the bigger male to take control and show off that aggressive side. Sven was in the mood for that and was already making moves to make that happen.

His hands roamed the under-rat's chest. Having their bodies so close, he could smell the thick musk that was radiating from Drova's body. The white under-rat was fresh from his own job and that made his natural smell all the more potent and alluring. In fact it was about time they had a bath but that could wait until after he had his fun...

When the kiss was broken, Sven focused his attention on another part of the bigger rat's body. Drova knew what it was and acted accordingly. He lifted his arms up, exposing the dense and soaked fur of his underarms. Doing this exposed them both to a distinctly earthier variant of the under-rat's body odor. Sven shoved his muzzle into the space as quickly as he could, taking in deep and loud whiffs while grinding his nose and lips against the muggy pit fur. Drova going multiple days without a wash actually worked in his favor. He got to bask in his partner's pit musk in its purest form.

"Just the way I like it..." Sven muttered aloud.

His muzzle was pressed even further into the armpit and he moaned directly against the thicker white fur. Rubbing it against that fur quickly got his facial fur wet well. After taking in repeated deep inhales the full brunt of his partner's scent was burned into the deepest parts of his nose. Sven absolutely loved it but still sought out more. Sniffing wasn't the only way he could enjoy this...

While still breathing in the rank odor, Sven also began dragging his tongue against the denser fur. Matching with the smell was the intense flavor that made the surface-rat melt in an instant. Powerfully bitter and lingering on his taste buds, the smaller rat found himself instantly addicted. As he continued to lick and sniff Drova was actively starting to blush. The warm puffs of breath and even warmer tongue were slightly tickling but being cleaned up via his partner's mouth was nothing short of arousing. Hearing his partner's moans of delight made him blush harder while also making his cock twitch and slowly rise.

The motions of Sven's tongue were done with purpose. He was actively trying to clean away the source of the musk but that was a futile task. The surface-rat knew from experience that his partner's scent couldn't just be cleaned away that easily, especially when it was left to build over multiple days. His tongue even combed through the pit fur but did little to dispel the sheer funk that continued to waft from the space. The area was made even wetter with his saliva and Drova was starting to pant softly from his own excitement steadily rising.

Sven pulled his face away but was quick to shove his tongue into the other pit with intent to do it all over again. Being treated to a completely unlicked pit that was ripe; radiating nothing short of pure musk, he eagerly attacked it with his tongue, getting right to the good stuff. He was again moaning as he pressed his lips into it. While also sniffing he began to suck on the pit itself. Having his muzzle shoved in so deep led to his moans coming out muffled. The strong flavors of both fresh and new sweat reached his tongue as he began sucking on it. In addition to the smells and flavors, Sven was also treated to Drova's soft moaning. Working his mouth and taking in as many whiffs as he could, the surface-rat had cleaned up the other pit as best as he could before pulling away.

He had his fill with Drova's pit musk but wasn't done with the bigger male just yet. He moved himself downwards while Drova remained standing. With both of his hands, Sven pulled the under-rat's loincloth down. Exposing the thick and sweaty cock led to a wave of cock musk wafting outwards. It reached his nose and Sven hummed, feeling his mouth watering right away. Just as he had with the pit, Sven pressed his lips to the shaft and felt Drova shiver from the contact. Right away his nose was treated to the reek that came from the combined elements of sweat, precum, cum and general grime that had come together to form a greasy sheen. The cock was glistening, a sight that the smaller rodent just couldn't resist. He began running his tongue along the semi-hard length, feeling it twitch against his taste buds.

Drova was quick to become fully erect from the licking. Sven took things even further. He hovered his mouth before the tip and pushed himself forwards, bravely fitting his partner's length in his mouth. While he had the bigger cock, Drova certainly wasn't small. The under-rat's erection was a snug fit but Sven had done this enough times to take on the shaft with experience. While fitting more of it inside Sven was already licking and sucking on the sweaty and greasy length.

Drova's moans were much louder now. Just as he adjusted to the feeling of being softly suckled on, Sven had taken things even further via bobbing his head back and forth. Sven was able to take his cock in without issue despite his size. While voicing his enjoyment, the surface-rat was noisily slurping and sucking even harder while running his wrapped lips along the length.

Sven loved the powerful flavors that met him and the smell that came from Drova's crotch was nothing short of intoxicating. The rankness made his head spin in the best of ways and his mouth never stopped watering. Now matter how much he moved his tongue about there was always more grime to clean up. While having plenty to taste he continued to also treat his nose to the unfiltered natural funk that clung to the bigger rat's sweaty crotch fur. To keep things fresh he even paused when reaching the tip again, taking a moment to dip his tongue underneath the foreskin.

Dorva couldn't help but bring his hand down to guide the other rat. He began pushing and pulling his partner's head, getting him to take in even more of his musky rathood. Precum was spurting from his tip, being unloaded from his heavy churning balls. Sven let himself be guided and actively encouraged his partner to do so. Knowing Drova so well, he could tell that the rat was starting to fall into his more dominant side. He just needed a bit more for it to fully take hold.

A low growl came from Drova. He began moving the other rat's head with greater speed and made sure that his cock was being plunged down into the tight throat. This was maintained until the other under-rat couldn't withstand anymore. Large amounts of his musky seed came gushing from his tip with force. Sven felt his muzzle and throat being pumped full and he could just barely manage to gulp it all down. The heat and stickiness of his partner's climax was running smooth down his throat, bringing him a sense of satisfaction. Drova still had a hold on his head and yanked him back, shooting the last of his spunk onto Sven's face.

The under-rat's breathing was heavier now. It was partially because of the lingering sensations from cumming so hard but Sven knew that his mate was ready. The more forceful and aggressive side of him was fully out. Drova's cock was still hard as it twitched and leaked right in front of the smaller rat's muzzle.

"Want more?" Sven asked, his tone of voice being soft and inviting. Drova was quick to nod and grunt. Feeling a shiver running down his spine, the surface-rat led the way to their large tub, big enough for them to both fit inside comfortably. The drain was already plugged thanks to Sven preparing him for this ahead of time. They both took off what they had left and got in the tub together. Leaning against the edge of it, he presented his ass to Drova and the bigger rat gazed upon it in a hungry manner. Without anything else being said between them, the under-rat moved in and he roughly took hold of the smaller rodent's hips.

His presented cock was pressed to Sven's hole. Precum was smeared by the tip being rubbed against the surface-rat's rim. Drova inserted his cock in a rough manner; shoving his hips harder led to them both moaning out. The fat cock was instantly surrounded by something so warm and tight. At the same time Sven's heart was pounding from the sheer filling he was made to endure. Sven clenched his tailhole down to tease his mate. It worked like a charm. Another low, almost animalistic growl came from the under-rat as he began easing his cock in and out. He pulled out about half of his cock before shoving it all inside again. Precum was still leaking out and it was quickly being rubbed onto those soft surfaces. Serving as a natural lube, the fluid was certainly going to be needed for what was to come next.

Sven proved himself capable and well versed in both giving and receiving cock. His insides had stretched around the fat rat tool but he felt nothing short of pleasure from it. He was holding onto the side of the sturdy tub, his body being rocked by every thrust that came from the bigger male. Drova keeping a hold on his hips kept him from being knocked about too much but it was best to play it safe. They were only just getting started and so far the under-rat was only showing a bit of what he was truly capable of.

Just as he predicted, his larger mate began thrusting in harder. His large balls were slapping against Sven's, the sound loud enough to be heard against their moaning. The smell of their mixed musks were hanging heavy in the air around them and the amount of precum being released by Drova was so great that it was spilling out of Sven's tailhole. When the fluid oozed out it was gathered within the plugged tub. Those fat balls swinging about and churning so hard led to a lot of excess pre being released as time continued to pass. They could both feel the precum starting to pool to the point that they were both kneeling in it.

The grip on Sven's body began even tighter and the speed was picked up on Drova's end. With the hasty ramming of his dick there were many messy sounds also being produced. The messy squelches and hisses of the under-rat's cock plowing into the overly messy and lubed hole. This led to Drova moaning out louder and his own cock was throbbing hard and shooting its own ropes of precum that slid down and joined the other rodent's. It was coming out freely and thick thanks to the prostate being milked by those strong and rapid thrusts.

Sven allowed himself to melt against the onslaught of thrusts. Being rutted with so much power and speed. His ass was being absolutely stuffed and his deepest parts were being touched in a way that forced him to shudder and exclaim with a slight pitch to his voice. It wasn't a sound he usually made but he didn't mind. It just meant that Drova was able to bring something out of him that nobody else had. He could feel the amount of fluids rising and that made him excited for an entirely different reason.

All of these factors came together to push Sven over the edge. Without touching his cock once the surface-rat was exclaiming and shooting more ropes of his own musky essence into the already partially filled tub. While he came hard his ass was also clenching down hard on the bigger rat's cock. Drova growled from the tighter hold on his length while Sven was left still groaning as his climax was pushed further than it would usually last.

Drova was fully focused on thrusting against those strong clenches while they still lasted. He held nothing back when rocking his body from this point on. His strong hips were moving as fast as they could and pushing with more than enough force to shove all of his inches as deep as they could possibly reach. Those messy sounds were even louder and more precum had come out to fill up the tub even further. Knowing that it was all he could do at this point, Sven held onto the tub's side and basked in the overstimulation that came from being rutted like this without a break from his climax.

In addition to the direct pleasure Sven was also feeling the hard pulses and flexes of his mate's cock in his ass. A few more hard slams of their bodies coming together were endured before the final one came. The ceased thrusts and the bellow Drova unleashed signified the arrival of his own climax. Keeping his cock in deep, the under-rat's cock swelled further before it began unleashing large amounts of hot and thick seed that first shot directly into the smaller male's guts. Sven could only endure so much of this and began to groan from the overfilling from deep within. Just as the precum had, the excess of his seed was spilling out and it was adding to the fluid already inside of the tub. The bigger rat was groaning and panting hard as he continued to drain his large rat balls. Sven also continued to groan as the seed was still spilling out of him in heavy amounts.

Sven felt how swollen his stomach was and the amount that was still leaking out of him. When it all came to an end his gut was left expanded and rounded. The cum was still so hot and thick, sloshing inside of him and around them in the bathtub. Drova pulled his cock free. It was still dripping, adding to the amount of fluids that was already collected in the tub. The smell of musk and cum was potent. It kept them both aroused and wanting for more. Running his hands over the smaller rodent's body, Drova began to caress the expanded stomach. It was given some smooth rubs before he pressed down on it. Sven groaned and clutched the side of the tub again as his stomach was forced to deflate and he released the cum into the tub, adding the overall amount they were already kneeling in.

Sven took his turn to be on top and Drova had no qualms getting on his back. His fur became messy with the amount of cum that had been collected. It was a large amount but they needed even more if they wanted to have a proper bath together. Turning himself around and getting in close to the bigger male, Sven gripped his cock and began pressing it into the under-rat's tailhole.

As soon as he was inside, Sven began thrusting in smoothly. The bigger male's ass felt so perfect around his cock. The great amount of cum around it made it easy for him to lube his cock beforehand. Reaching in deep led to his shaft touching Drova's prostate and forcing him to react. He was soon moaning out, completely submitting himself to the smaller male that was penetrating him. Sven was instantly taken with the hot, slick, and tight hole that surrounded his inches and the deep moans that came from his mate served to encourage him further. His body was pulsing and every breath he took brought more of that deeply musky smell to his nostrils.

It didn't take long for the pace to become even faster. Sven started out strong and held nothing back as usual. He was even rocking himself with enough force to move the bigger male's body. Groans came from him as he did this. He could never get enough of pounding into the under-rat and making him moan. Drova let the other male take control and was more than happy to do so.

"Oooh..! S-Sven..." Drova groaned. Being rocked against the tub and feeling his ass becoming hotter and sloppier was nearly too much for him to withstand. Sven was aware of this. The clenches of his partner's ass gave him something even better to hump against. Aiming for that prostate purposely, Sven gave the other rat a reason to keep squeezing down on his pumping length. Doing so made the pleasure rise for him as well and that gave way to him unleashing more precum.

While rocking his hips in a smooth and unconscious manner, Sven reached out to start stroking his mate's cock. He began stroking it while still thrusting into the soft and tight hole. While pumping his hand up and down the smaller rat would pause to play with the foreskin as well. This of course got a bigger reaction out of Drova. Sven smirked as he continued to overwhelm the other male with a dual onslaught of stroking and thrusting. Precum was freely leaking from the bigger male, proving that he had more to give despite the big load he had blown before. Stroking his prostate ensured that he would continue spilling the rest of his balls' contents.

Sven needed only a few more thrusts to make Drova cum. The constant prostate contact and jerking led to blowing another huge load. This time it was gushing out freely coating their already smelly and greasy pelts. Drova was groaning loudly and deeply as his climax persisted and Sven was right there, still thrusting and stroking to make sure that he spilled every drop that he could possibly give. It all flowed down their bodies and was collected in the tub. The amount of seed had risen a lot just from that climax and Sven was still determined to fill it up even further.

He didn't stop his thrusting. There wasn't even a break in between. The stroking hadn't stopped either. Drova gripped the tub's side with one hand and was huffing heavily through clenched teeth. No letup was given: in addition to the continued stimulation, Sven was also thrusting his cock in with even greater force. This caused the surface-rat to reach his peak as well. Rather than pumping his seed inside of Drova, he was quick to pull out and released onto the bigger rodent's body, shooting his spunk so it could join the amount that was already pooling around them. Still being stroked all the while, Drova also felt a rise of excitement from the hot cum splattering onto and oozing down his body. It was enough to make him cum again even though he just expelled a great amount of musky spunk, Drova reached another climax and began shooting again as well.

Sven still wasn't done. As soon as his own orgasm had finished his still hard cock was jammed back inside of the overwhelmed under-rat. Pushing it in deep again and striking the prostate again, he was being treated to more squeezes from Drova's anus. Drova did his best to hang on while the intense pleasure continued to course through him.

Drova had already been pushed to his edge multiple times and had no more to give. He was just left panting and gasping from all the intense feelings that were forced into him. But he was loving every second of it. They could both feel that the seed had risen, being so hot and thick. So much of it was clinging to their pelts. They just needed a bit more and they would be able to properly bathe into their mixed spunk.

He was soon brought to another finish; his cock throbbing again and spurting another huge amount of cum. This was done after he had pulled out again. They continued to do this for hours, taking small breaks while basking in the warmth and thickness they bathed in. Slathering each other in the fluid kept their pelts smooth, shiny, and greasy. It also kept their own natural smells strong. Regular cum baths had made Sven's pheromones even stronger than they already were. This was kept up until Sven had released the last of what his own balls could give. He had been jerking his cock while doing so, milking more out of himself and adding to the amount in the tub. He was panting hard and so was Drova. Soon enough they were both panting and finally able to come down from the intense sensations of so many back to back orgasms.

They were able to fully enjoy the bath, simply relaxing in the steaming pool of hot spunk that treated their noses to a delightfully strong scent. They smeared even more of it onto their bodies and began to kiss. Drova had a bit of cum in his mouth and the two began to trade it back and forth with their tongues, both moaning from the flavors they were greeted with. Rubbing them together and smearing the stuff onto their taste buds, the two broke the kiss and there was a rope of cum that still kept them connected. Giving each other a smile, they both sighed and let themselves sink further in the pearly and musky fluid...
