The sun was beating down on Diesel's back as he dug his paws into the soft dirt. His black and white fur was already covered in dirt, but he was never bothered by that. In fact, he relished in the feeling of the cool earth against his fur. For Diesel, digging was more than just a hobby, it was a passion. And he was damn good at it. Not everyone understood his love for digging and getting dirty. Some saw it as a nuisance, while others were simply amazed by his skills. But Diesel didn't care what others thought.

At 18 years old, Diesel was still as enthusiastic about digging as he was when he was just a pup. But there was something different about him now. As he dug deeper and wider holes, he couldn't help but notice a strange sensation building within him lately. It was a feeling of excitement and arousal, a feeling he had never experienced before.

At first, Diesel didn't understand what was happening to him. But as he continued to dig, his body would of course become dirtier and dirtier. This happened so often that it caused Diesel to realize that he was getting turned on by digging.

It was a confusing and exhilarating realization for Diesel. He had always loved digging and getting dirty, but now it was taking on a whole new meaning. As his erection grew harder and harder, Diesel couldn't help but let out a low growl of pleasure.

He was in the backyard with some of his other siblings but was a good distance away from them so his digging wouldn’t bother them. Diesel glanced around, making sure no one was watching him, becoming all the more aware of the dirt against his fur and the growing ache between his legs.

With each swipe of his paws, Diesel could feel the dirt breaking away and landing on his already dirty pelt, sending shivers of excitement throughout his body. He was now purposely trying to get himself as dirty as he could, feeling his spotted pelt becoming more caked and his clothes were catching even more of the earth. 

Unable to stand his own arousal any more, he brought one paw down to rub at his tent, shivering a bit from the touch. He kept his ears perked so he could hear anyone approaching while pulling down his shorts and underwear down to his ankles. Of course doing things like this were to be done in private so there was an extra sense of thrill from being outside in the backyard with his siblings being just on the other side of the backyard. 

His paw began to slide up his erection and back down again. Diesel felt a shiver race through his body, from head to toe. He had jerked himself off plenty of times but this was the most excited he had ever felt about doing it. The dirt-streaked dalmatian blushed and bit his lip just from the thought of someone walking up and seeing him. That caused him to jerk at his cock harder, making precum leak from his tip. Small noises came from him from the pleasure that was spreading throughout his body. 

He didn’t know why the need to get off was so strong but now that his hand was moving, Diesel felt he couldn’t stop himself even if he wanted. Still keeping himself quiet, Diesel was moving up and down the entirety of his length, going from the tip down to the base and back up again. 

More precum was coming from the tip. His cock starting to pulse was bringing out even more of the fluid. It began to leak down his fingers, sticking to his fur and even mixing a bit with the dirt that was on them. Seeing this made him all the more aroused and it was suddenly feeling even better. 

Using the clear fluid, Diesel had an easier time sliding his hand, tugging his foreskin along in time with his hand’s movements. And as things were becoming better more precum was coming out to make the pleasure and slickness greater as well. 

“Mmm…” he groaned softly, feeling every throb of his cock against his wrapped fingers. Now he began to move a bit faster and that meant he had to put more effort into keeping himself quiet. It wasn’t that hard at first but as things got more intense Diesel found that it was getting much harder to keep himself contained. 

Now he was working at a steady pace, his hand keeping a comfortable grip on his length, giving it not just strokes but also rubs with his fingers and teases of the foreskin. He allowed himself to moan just a bit while enjoying the combination of direct pleasure and the excitement of having his body covered in dirt. 

Diesel looked down at himself, his stocky body and the earth that acted as more spots that were covering his body. Now he was looking at it in a new way. He could feel it clinging to his pelt. It had rained recently and the dirt below the grass was wetter, being more akin to mud and it was all over his lower half. More precum was coming out, showing that he was more pent up than expected. 

He stopped for a moment so that he could look around to make sure that nobody was seeing him. His free hand roamed over his body, making contact with the wetter and more mud-like earth. Making circular motions with his fingers, Diesel began to rub it deeper into his pelt, feeling it making contact with his skin. Seeing that the coast was clear he resumed his stroking. 

Now he was starting to feel his climax approach so he slowed the pace in order to keep himself going for just a bit longer. The hand that had been rubbing his body was sliding down to fondle his balls. Stroking himself and rubbing his balls at the same time, Diesel’s pants were becoming deeper and he couldn’t help but squirm from the two kinds of pleasure being felt at the same time. 

Coming all the closer was Diesel’s climax, focusing on the dirt that was all over him and his clothes along with the great amount of precum that had come from his tip, the spotted canine’s tongue was lolling from his muzzle. His hand was so slick and warm with precum, acting as a perfectly lubricated sleeve. 

Diesel finally allowed himself to go fast  and hard, pumping his hand rapidly while also putting more effort into his ball-fondling. Wet with a mix of precum and a bit of wet earth as well, the stocky dalmatian was reeling from the substance that was being smeared over his orbs. Even through the mixture he could feel the furry spheres churning harder just as his cock was pulsing harder. That’s when it finally struck him. He was going to cum and was quick to point his cock at the dirt.

Diesel could feel that a big load was brewing within his orbs and now it was time for him to let it all out. The first rope of cum shot from his tip, blasting out with more pressure than he expected. There was another to come right after, all splattering against the wall of dirt in front of him. 

There was so much of his cum shooting out, making a bigger mess that was sprayed against the earth and sticking firmly to it. While cumming so much, Diesel was basking in the sheer pleasure of finally being able to take care of that need. He managed to pump his length a few times while still shooting his ropes, making even more come out and mark the side of the hole. When he was finally done the dirt-covered dalmatian was still panting and trembling a bit. 

Once he came down from the heavy amount of bliss, Diesel was quick to slip his shorts and underwear back on and he covered the cum with more dirt. He looked around and thankfully found that nobody was around in fact those who had been outside with him were no longer there anymore. 

There was someone still outside and they walked up to the hole, seeing Diesel with his fur and clothes covered in dirt all over. 

"Diesel, you've got dirt on your clothes again," Dylan said disapprovingly. "You're all muddy."

Diesel looked down at his fur, then up at his brother. "Mud's going to get on you when you're digging, Dylan."

Dylan huffed, gesturing to his brother's freshly dug hole. "You're just making a mess." He crossed his arms, waiting for Diesel to climb out of it. 

Diesel looked at the “mess” he'd made, then back at Dylan. "But I’m always digging holes!" He scratched his ear, then shrugged at Dylan playfully.



“But you’re not a kid anymore, Diesel.” Dylan sighed and rolled his eyes. "You need to get cleaned up anyways if you want to come inside and have lunch," he said, trying not to sound too harsh. He pointed Diesel in the direction of the garden hose and turned it on. While his brother climbed from the hole and approached the hose, Dylan stayed behind and attempted to clear away some of the dirt that was all over the place thanks to his brother’s digging. 

He was unaware of Diesel stripping down before he took hold of the hose himself and started spraying water on himself. As he did so, he accidentally got some water in his face and sputtered, laughing and shaking water out of his fur. When he finally finished washing up, Dylan was approaching, looking up just in time to see Diesel turning around, revealing his bare chest and a very large, uncut appendage hanging between his legs. Dylan's eyes widened in shock and surprise.

"Diesel!" he exclaimed, "Why are you naked?" He gestured awkwardly at his brother's exposed genitals.

Diesel looked down, a little confused. "What's the matter?"

Dylan blushed even more. "You know! That thing! Your...privates!" He motioned between them, his voice a little squeaky.

Diesel scratched his head, still confused. "But we're both guys. It’s no big deal. You have one too."

Dylan blushed even deeper, still unable to look at his brother's crotch. "I-I know, but we're not supposed to show them to each other. It's private." He tried to avert his gaze as Dylan continued to stand there, feeling extremely uncomfortable.

Diesel tilted his head, genuinely confused. "But Dylan, we've seen each other’s before. Remember in that changing room at the pool park? It's nothing to be ashamed of." He reached down, gently cupping his member with one paw. "See? It's not scary or gross." He gave his brother a playful wink.

Dylan did remember that but he also remembered himself doing all that he could to change quickly so he didn’t have to see his siblings in the nude or spend too long in the unsanitary looking space. 

"Diesel, stop," Dylan said, his blushing growing stronger. Though he was protesting the older dalmatian couldn't help but keep looking at the younger one's big erection. It was long and thick even while flaccid.

"What's wrong?" Diesel asked innocently as he walked up to Dylan. “It’s just the two of us out here.” He gave his brother a playful nudge with his paw.

Even if Diesel was an adult, he still had his playful and even childish nature, still loving to play games and of course dig holes that were even bigger now thanks to how much he had grown, taking after Doug and having a mix of bulk and softness. He licked to eat a lot but digging by hand required a lot of hard work that also served as exercise. If having his sibling’s length hanging out wasn’t enough Dylan also noticed that Diesel had only managed to wash off some of the dirt from his pelt. Now he was naked, wet, and dirty, pressing himself close to his older yet lankier brother…

"Ugh… Just…fuck me, Diesel!" Dylan groaned, feeling exasperated. Diesel was again confused as to why Dylan would want that but he knew better than to disobey his already annoyed brother. 

Being already so close to Dylan, Diesel was easily able to pull his brother’s pants down, followed by his underwear. Dylan was so shocked that he didn't react until he was already nude. Diesel turned him around and pushed him against a nearby tree. Then Dylan felt something hard and warm poking at his rear. 

Dylan's face turned even redder. "Diesel, that's not what I meant. You can't just... do that!" He tried to push his brother away, but Diesel was surprisingly strong for a dog his size.

"I'm just doing what you told me to," Diesel said as he proceeded.

Dylan's face contorted in discomfort and embarrassment as he felt his brother's member pressing against his anus. "Diesel, you-!" He didn't get to finish his words as Diesel began pushing.

"It'll be okay, Dylan," Diesel said, his voice a mixture of reassurance and excitement. "Just relax." He continued to push, lubricating the tip with his saliva as he did so.

Dylan's face contorted even further as he felt the intrusion. It hurt and it was uncomfortable, but there was also a strange, almost pleasurable sensation building up inside him. "Diesel, stop!" he managed to choke out. 

Diesel felt the resistance lessening and pressed forward, finally penetrating his brother's tight hole. "Ahhh..." he moaned, feeling an intense rush of pleasure as he sank in deeper. He began thrusting, his movements growing more forceful and rhythmic as he found his pace. "Is it okay, Dylan?" he asked breathlessly, his words muffled against the older dog's fur.

Dylan let out a shaky breath, feeling overwhelmed by the sensations coursing through his body. "Diesel... Dammit..." he managed to say, but at the same time, there was a strange, almost addictive sensation that made him want more. He felt his own body beginning to respond to his brother's movements.

As they continued, Dylan's mind drifted, lost in the haze of pleasure. He had resisted at first but that quickly passed and now he didn’t want this to end, and thought about nothing else but the feeling of Diesel's hard cock plunging inside him. The younger yet bigger dalmatian was working his hips with surprising expertise.

Dylan felt his own climax building, his body tensing and ready to explode. "Diesel..." he moaned, his voice hoarse. "I'm... I'm close..." In response to this his younger brother picked up on the warning and sped up, thrusting harder and deeper as Dylan's orgasm crashed over him in a wave of ecstasy. He arched his back, letting out a long, shuddering moan as his seed was spilled onto the bark of the tree.

Diesel felt the younger dog's body tense up against him and he knew that Dylan had just reached his climax. He let out a groan of satisfaction and thrust one final time, feeling his own release as he filled his brother with his seed. Their bodies entwined, they stood there, panting and sweating, their hearts racing.

For a moment, they both stood in silence, taking in the intensity of what had just happened. Then, with a sheepish grin, Dylan looked back at Diesel and said, "Wow, I didn't expect it to be like that."

Diesel was still holding onto Dylan, grunting in response as he started moving his hips again, taking his older brother by surprise.

"D-Diesel...!" Dylan stammered, feeling the younger dog's cock slide deep inside him again. Diesel couldn't believe how good it felt, how tight and warm. Now that he had cum inside, Dylan's hole was perfectly slippery and so easy to thrust into.

Dylan's eyes rolled back in his head as he felt a more intense pleasure surge through him again. He let out a low moan that quickly turned into a high-pitched whine as Diesel’s thick length pressed on his prostate. The younger dog's movements were perfectly synchronized with Dylan's own, driving him wild with desire.

As they continued, their bodies slid against each other. The water and wet dirt of Diesel’s body was being rubbed onto his own pelt but for once Dylan didn’t mind it. Dylan could feel himself throbbing all over again as he started moving his hips to meet each of Diesel's thrusts. The pleasure of their combined actions was almost overwhelming, and he found himself wishing that this moment could last forever.

His stocky body grinding against his thinner older brother's, Diesel was rubbing more of the dirt on his fur into Dylan's. The always neat dalmatian would have complained but he was too focused on how good it felt to be filled with every thrust.

Diesel's pace was timed and powerful, his hips flexing as he drove his manhood deeper and deeper into Dylan's ass. He could feel his brother's muscles tensing and relaxing around him, the hot and wet walls gripping him like a vice. The older dog's moans filled the air, echoing back and forth in the backyard, their movements becoming more and more urgent.

Dylan could feel the pressure building inside him, his second orgasm imminent. He pushed himself back, pressing himself harder against Diesel, their bodies sliding against each other in a wet, animalistic rhythm. His breath came in ragged gasps as he neared the brink, his hips moving in time with his brother's thrusts.

"I'm almost there again..." he panted. 

In response Diesel just grunted again, focused entirely on rocking his body over and over. 

With a final, powerful thrust, Diesel buried himself to the hilt inside Dylan, the tip of his cock massaging the skinnier dog's prostate. Dylan's muscles tensed and then he was cumming, his hot seed spilling out over the back again and onto the grass. He moaned loudly as wave after wave of pleasure coursed through him.

Diesel felt the extra tightness from Dylan's release, and knew that he didn't have much longer before he would cum as well. His hips bucked violently, driving himself deeper inside his brother, as he tried desperately to hold back his own climax. He could feel the pressure building inside him, his cock throbbing from the need to release.

Dylan was clinging to the tree, his body shaking as his seed was still spraying onto the bark and grass.

"D-Diesel..." he panted, still trying to catch his breath.

The younger dog snarled, his pace not slowing down at all as he continued to drive his shaft into Dylan's squeezing tailhole. His cock was throbbing so hard and his orgasm was building up with every thrust. Dylan's muscles were still tightening around him.

"You're so...so tight," Diesel groaned, his voice strained from the effort of holding back his climax. His eyes were half-closed, focused on the pleasure that radiated through him. The grass beneath them was wet from the water dripping from him and Dylan’s cum, but he hardly noticed.

Dylan felt the younger dalmatian’s cock twitch inside him, and then with a final thrust, Diesel released his seed deep inside him. The hot, salty liquid filled him up quickly for a second time.

The older sibling moaned loudly as he was overwhelmed by the sensation of being filled to the brim with his brother's cum. It was unlike anything he had ever experienced before, and it was intensely arousing. He felt so connected to Diesel at that moment, their bodies intertwined and their fluids mingling together on the ground.

Diesel collapsed on top of Dylan, his weight pressing the younger dog from the tree and onto the soft grass. Their chests heaved together, their breaths hot and ragged against each other's fur. The younger dog's cock twitched within Dylan's ass, still oozing out a trickle of cum as it began to soften.

The two dogs lay together for a long moment, basking in the afterglow of their passionate coupling. Dylan closed his eyes for a bit, relishing the warmth that spread through his body.

“O-okay. I think it's time to get-” Dylan was unable to finish as Diesel pulled his cock free and allowed the cum to leak freely from his stretched hole. His brother’s big and slightly dirty hands were on him, easily flipping him over. Seeing that Diesel’s cock was still hard made Dylan gulp. There was also a lustful look on the younger canine’s face, as if he was lost to the need for more. 

Diesel moved his body up, his balls dragging over Dylan’s chest while his big and long cock hung over the lying canine’s muzzle. 

Before Dylan could even process what was happening, Diesel's warm, rough hand guided him up to the impressive erection. Dylan's heart raced as he felt the heat emanating from Diesel's member, and his own arousal grew more and more intense with each passing second. Finally, with a gentle shove, Diesel had Dylan receive the tip. Dylan didn’t resist and closed his lips around the head of Diesel's cock, tasting the salty pre-cum on his tongue.

As Dylan began to bob his head up and down, sucking and licking at Diesel's length, he felt his younger brother's hips begin to buck, meeting his movements with a rhythm that was both forceful and irresistible for him. The sound of Diesel’s breathing grew heavier, the air between them thick with growing desire and need.

"Faster…" Diesel urged, his voice rough and hoarse. "That feels so good." He gripped Dylan's hair, pulling him closer as he thrust deeper into his mouth. 

As if fueled by his brother's words, Dylan's movements became more wanting and urgent. He sucked harder, bobbing his head up and down on Diesel's cock with an added smoothness, teasing the sensitive foreskin with his tongue when pulling back. When it was pushed forwards again, Dylan could feel the head of Diesel's cock brush against the back of his throat this time and that sent shivers through his entire body.

The light taste of sweat and heavier flavor of precum on his tongue only served to heighten Dylan's need for more. He moaned around his brother's cock, relishing the flavor and the pulsing against his tongue. His own cock throbbed with desire, pulsing and leaking pre-cum.

Diesel gripped Dylan's hair more firmly, pulling him closer as he thrust deeper into his mouth. The sensation of his brother's length stretching his throat made Dylan moan out even louder. With every thrust, Dylan felt the head of Diesel's cock touching the back of his throat, leaking streaks of precum that would be swallowed by him. 

As his younger brother's hips began to buck wildly, Dylan could feel the heat emanating from the shaft and the veins pulsing beneath the thick skin. The intensifying taste of Diesel’s precum on his tongue only served to heighten Dylan’s arousal and the intensity of his actions. With every thrust, he swallowed around his brother's cock and urged him on via even louder muffled moans. The sound of their respective labored breathing filled the air, loud enough for the two to hear each other but not loud enough to be heard by those in the house. 

Diesel's hands gripped Dylan's head, his fingers tangled in his hair, guiding him as he started to really fuck his older brother’s face. The sensation of being so completely taken, of being owned by his older brother was way more exhilarating than he expected it to be.

Dylan continued to suck and lick at Diesel's length as best he could, reacting to the building heat emanating from his body, the strength in his grip. He could feel every muscle in his brother's legs and thighs tense when he would thrust with force into his mouth. Along with being roughly handled like this, the taste and smell of Diesel  was even more intoxicating, a mixture of sweat, pre-cum, and the earthy scent of dirt that Dylan didn’t mind for once. 

With a guttural groan Diesel thrust one final time into Dylan's mouth. His body tensed, his cock swelling and pulsing as he released his seed, filling Dylan's mouth with his hot, salty cum. The sensation was near overwhelming for Dylan as he swallowed reflexively, feeling the warmth of Diesel's seed flow down his throat and into his belly.

As his brother's hips finally relaxed, Dylan pulled back, their bodies still pressed together, his face flushed and lips a bit swollen from the intense experience. He looked up at Diesel, their chests heaving in unison, their eyes locked in an intense gaze. 

“A-are you done now?” Dylan asked once he caught his breath. Diesel nodded and the lankier dalmatian smirked. “Good.” With an unexpected amount of strength, Dylan managed to not just lift Diesel off of him but he got the heavier dog against the tree and onto his knees. Diesel blinked, the first thing he noticed was his sibling’s cock hanging in front of his face. 

”Now put it in your mouth!” Dylan said firmly. Even if he enjoyed the experience, he was still very irritated with the way it all played out and figured the best way to soothe his hurt feelings was to give Diesel the same treatment. 

Diesel wasn’t fazed by the harsh tone or look on his brother’s face. He was solely focused on his brother’s length. While not as big as his own it was still a good size, one that he was more than happy to interact with. “Okay!” he said with enthusiasm, bringing his hand up to grip Dylan’s length by the base so he could pull it closer to his lips. 

Not realizing that this was a punishment of sorts, Diesel started right away with kissing the tip and getting himself acquainted with the flavor of Dylan’s pre, finding it was similar yet different when compared to his own. That small kiss turned into a lick to get an even better taste of the substance. While he hummed from it Dylan let out a more breathy light moan. 

After getting a good taste for it, Diesel went right ahead with opening his muzzle and just pushing it down on the older dog’s cock. He wasn’t hesitating, licking and suckling on the flesh while more of it was sliding past his smooth lips. Dylan was again reeling from the feelings that were injected into him. Diesel definitely proved himself skilled when it came to being in the top position but now he was showing that he was just as, if not even more capable when receiving his length.

Dylan tilted his head back and moaned out, unable to contain himself. The wetness and texture of Diesel’s tongue felt better than he expected, especially since Diesel somehow knew just what to do. Without pause the stockier dalmatian was sucking while moaning softly. 

“Oh, Diesel…” Dylan huffed. He knew it was best to keep himself quiet but that was hard to do when a simple lick and suck was all it took to make him shake. Taking a page from his brother he reached down with trembling hands and pressed them to the back of Diesel’s head. The still damp and dirt-streaked dalmatian felt this but continued to orally perform, not even resisting when Dylan began to push his head down further. 

Now all of Dylan’s cock was stuffed in and Diesel could feel it in his throat as well. His lips were still wrapped and his tongue was still moving all over while his nose was pressed firmly to Dylan’s crotch, allowing him to take in the familial and exotic scent of his brother’s arousal. 

Dylan looked down and saw just how much Diesel was enjoying himself, not just moaning but having his eyes lidded while still working his muzzle, clearly enjoying the act itself even if it wasn’t giving him direct pleasure. It was hard to stay mad at the other dalmatian, especially with the need for more taking precedence over his other feelings. 

Diesel took it upon himself to pull his head back before pushing it forwards again. He began to do this over and over again, getting himself into a rhythm of bobbing his head while Dylan’s hands were still on it. He kept his lips pressed snug to the girth of his older brother’s shaft and his long tongue continued to trace and swirl all over what it could reach. 

Dylan could feel it all as if time had slowed down. The way that Diesel’s tongue was moving about, flicking and grinding all over his cock. It was tracing over the underside and even his foreskin was given attention as well. Extra sensitive spots like that being touched and teased was more than enough to keep Dylan moaning and trembling. 

“Mmmm…. D-Diesel…” Dylan groaned, finding it hard to even form words against the onslaught of smooth tongue movements. His tongue hung from his open mouth as he began to pant, failing to resist the urge to buck his hips against the soft lips and moving tongue, desiring every bit of pleasure that he could get. Doing this caused his cock to go into Diesel’s throat where he was met with additional tightness and warmth. 

Even with his throat being penetrated, Diesel kept up the sucks and licks, feeling the shaft pulsing harder and feeling the precum running down into his stomach. It was quickly swallowed down and when the shaft pulled back Diesel welcomed the taste of it on his tongue. The optimist dalmatian very much enjoyed the feeling of having his throat used by his older brother, feeling the inches sinking down his windpipe. In time with Dylan’s next thrust he pushed his own head forward, managing to get the cock to reach even further down.

It didn’t take much more for Dylan to get lost in the pleasure, rocking his lower half with a bit more force and speed, keeping his cock plunged into his brother’s throat, rubbing it against the hot and slick walls. His balls were swinging in time with the pushes, knocking into the other dalmatian’s chin. 

It got even better when Diesel would swallow against his cock, making the pleasure increase while also milking out even more of his precum. Dylan couldn’t help but moan out louder, feeling the approach of his climax. It was getting closer with every hump from him and suck from Diesel. 

His moans turned into heated grunts and growls as he felt himself getting all the closer to his limits. He could feel his balls churning hard, ready to send their contents along through his shaft. Using the hands that were still on his brother’s head, Dylan pushed Diesel’s head down in time with his next thrust. He managed to get his cock far down and he kept it there as he continued humping against the soft and snug walls. 

Dylan managed to last another minute of this but before he growled and reached his limit. He could feel his cock throbbing incredibly hard as it swelled. As it jumped against the walls of his brother’s throat the length was shooting ropes of his seed that were swallowed by Diesel, getting the stuff down into his stomach while making the pleasure of blowing his load even greater for Dylan. 

He kept himself pushed into the other dalmatian’s throat, feeling every pulse and squirt of his cock against the wet walls. He managed a few shallow humps that continued to milk out his seed. All the while he was reveling in the deep pleasure that was coursing through the entirety of his body. 

Diesel was handling it all, the fill of his throat and the steady amount of seed being ejected from the tip. The more he gulped, the more intense that the feeling of heat and stickiness was in his stomach. 

Dylan sighed deeply when he pulled his cock free, noticing that there was hardly any seed left on his pulsing length. Diesel managed another gulp before he looked up at his older sibling expectantly. Even though he had cum so hard he was still erect and needy for more. Now that he had felt the pleasures of Diesel’s mouth and throat, Dylan was eager to feel the other end, like when he had been pushed against the tree and used. 

Aiming to give his brother a taste of his own medicine, Dylan had Diesel turn around and bend over. Diesel did so, reaching his hands out and taking hold of the tree’s trunk. He was in the perfect position, his sizable rump sticking out and for what Dylan had planned he at least wanted to make sure that his sibling was prepared. 

So he got down and came in. Usually this was something that Dylan would be on board with doing. For one he was getting himself close to his brother’s rump and even though Diesel had gotten wet with the hose his backside hadn’t gotten touched much, leaving it with the most spots of dirt. He just did it anyway, sticking his tongue out and touching it to the rim. Diesel perked up and shivered a bit, feeling a tingle racing through him. He felt his brother’s tongue sliding in and his body responded by squeezing down on it. 

Dylan was thankful to find that his sibling’s hole was clean but it did smell a bit from sweat but he managed to power his way through that, daring to just slide a bit of his tongue inside. The rim was being stretched as more and more of the muscle eased in slowly, causing his tongue to slowly slink further inside of the bigger dalmatian’s tailhole until nearly the whole thing was in and his lips were touching Diesel’s soft rim. 

Dylan continued to lick, putting more effort into his movements, finding that it wasn’t as bad as he expected. His long canine tongue made contact with the walls and started to rub against them. Another firm clench of Diesel’s hole came in reaction to this. It made him pant softly and from his hard cock, a squirt of precum was released onto the bark of the tree that still had Dylan’s load clinging to it on the other side. 

Now that he was being licked, Diesel was really taking notice of the way that Dylan was starting to rim him. They were light and shaky at first, as if the neat-freak canine was trying to prepare his hole while also making as little contact with his walls as possible. But Dylan seemed to have gotten used to it as his licking had noticeably become smoother and more pressure was applied as well. 

Now that he was really licking the warm surfaces, his saliva was being left behind, making them wet as well. That wetness was spreading and becoming more intense as Dylan was really getting into it, not minding the bit of sweat and the dirt that was getting onto his face from Diesel’s squirms. 

While Dylan was gaining more excitement from licking even deeper and with more force, Diesel gasped when his prostate was touched. Dylan noticed this as well and made a note about the spot and how sensitive it was. 

Diesel didn’t know what to expect at first but as the licking was deep and consistent it was hard for him not to melt against the pleasure of having his tailhole licked and lubricated by the other canine’s lengthy and smooth tongue. His own cock was throbbing harder while also leaking more precum onto the grass. Sometimes it would spurt out with greater force when more tender spots of his anus were touched and pressed, making the mess in front of him and between his legs all the larger. 

Dylan had gotten used to this and was licking more than just the prostate, finding that there were more spots inside of his brother that would make him moan out. He felt the passage squeezing against his tongue but he continued licking. He had licked enough to get the whole thing all wet but he just kept going, gaining a sense of enjoyment from the simple act that was giving the dalmatian more and more pleasure. 

This caused Dylan to keep licking at the spots that were the most sensitive. Going back and forth between them he found that some had more of an effect on Diesel. The next lick was him pressing down with more force and that made Diesel groan out again, his body trembling and his claws digging into the bark some. 

So focused on his own actions, Dylan didn’t notice that Diesel was stroking his own cock while being deeply licked. He was pumping his paw up and down, using his leaking precum to smoothly slide up and down his inches. While jerking himself and being rimmed so deeply at the same time, Diesel could feel himself being pushed all the closer to his orgasm and the next pump in time with another hard lick caused him to reach that point. 

He huffed through clenched teeth, feeling his cock pulsate in his hand while more of his cum was spraying out in thick amounts, coating the side of the tree and then the grass as well. 

Realizing that he had made his brother cum, Dylan pulled back, leaving his brother’s hole wet and winking. He had done more than enough and all of that licking had made his erection rock hard. Still on his knees, the older dalmatian rose up and came in close, outstretching his hands but he hesitated just short of placing his hands on his brother’s backside. 

”What’s wrong, Dylan?” Diesel asked, looking back. “Not scared of getting a little dirty, are you?” he asked. He was referring to the fact that even his hips and rump cheeks also had dirt on it, dirt that Dylan would have to make contact with but he had already come this far already…

He closed the small amount of distance between them, lining his cock up with the wet and slightly stretched rim. The both of them were brimming with arousal and excitement as Dylan prodded a few times before he slowly started to ease himself inside. 

”Ooh…” Diesel moaned, feeling himself being filled by his brother’s length and then he was being rocked a bit by the other canine’s humps. Dylan was starting out with some force behind his movements, gradually sinking in more and more of his inches until the entire thing was sliding in and out. 

“Wow…you’re really tight…” Dylan said with his voice quavering. He was by no means a virgin himself, having Hansel to thank for that but Dylan wasn’t prepared for the snugness of the other dalmatian’s hole and the inherent exhilaration of doing this with his sibling. 

He grunted and began to pick up the pace, holding onto his brother’s slightly muddy hips even tighter and he felt his cock being pushed in as far as it could go, being pleasantly constricted by the slick depths. Any of his remaining resistance slipped away and he put more effort into his thrusts, powering through the added tightness of the tailhole that was clenching even harder as the prostate was pressed with greater power. 

Diesel was just starting to drift off from the feelings when the thrusting stopped entirely. He didn’t have the chance to wonder why as he felt the cock pulsing against his walls and then there were spurts of warmth. He realized what was happening as Dylan was grunting and shaking from cumming much faster than he intended to. 

“That was it?” Diesel asked, actually sounding pretty disappointed. He could feel the cum inside of him, keeping him excited and his loins tingling. 

”S-sorry…” Dylan blushed. His length was still lodged inside, surrounded by greater warmth and wetness thanks to his seed. “Just give me a moment…”

When Dylan did manage to catch his breath, Dylan didn’t immediately start again. First he guided Diesel onto the ground and on his back again. Dylan got in between the stockier dalmatian’s legs, resting his paws just beneath the ankles of his sibling’s upturned footpaws. He took a breath and pushed himself back inside of the warm hole, picking up where he left off with firmer thrusts at a slower speed than before so he could better pace himself. 

Diesel immediately began moaning and panting from his tailhole being penetrated from Dylan’s length sliding back and forth. This rougher but evenly paced rutting was sending waves of pleasure through him. His depths were penetrated, stretching around the tip and inches that would sink in and pull out. 

There was no discomfort felt on Diesel’s end thanks to the rimming that had stretched and lubed his hole earlier along with the cum that acted as the perfect lube. His own cock was throbbing harder as well, swinging from the rest of his body being moved and also leaking precum more and more from the steady pressing of his prostate. 

Along with the cum that was already inside of him and smeared all over, there was the added heat and wetness on top of that from his precum leaking from the tip of Dylan’s moving cock. 

Diesel again got lost in the pleasure but he was snapped from his daze when there was something else he felt. Dylan’s paws had been resting on his ankles, having a hold on them both but he was feeling something tracing over the sole of his footpaw, running over the pads. He looked on with confusion and then surprise to see that Dylan was actually running his tongue over it. 

”Dylan? What are you doing?” Diesel asked. 

Dylan didn’t respond, just keeping it up. He didn’t want to be actively told what he was doing but didn’t want to stop either. Diesel said no more and felt the increasing warmth of his paw being teased by the other canine’s long tongue. He ran it from the heel and up to the toes, tasting both a bit sweaty and also a bit of dirt as well. Though this was obviously something he wouldn’t usually do, Dylan was starting to develop an excitement towards the dirt that was on Diesel, the way that the other canine just wore it on his body, making it essentially another part of him. 

Having his footpaw licked while also being pumped into was just too much for the stocky dalmatian to handle anymore. He raised his voice and came again, spilling his load directly onto his already dirty fur, adding the wet stickiness of his cum to the ruffled fur of his rising and falling belly. 

Dylan stopped licking so that he could focus on pushing through the clenches that came from Diesel's orgasm. He pushed against them a few times before he groaned out and came hard for a second time inside of his brother’s tailhole, filling it up with his seed all over again. They both voiced their pleasure together, not bothering to keep themselves quiet until they both came down from their highs. 

When it came to an end, they were both feeling fully satisfied. A small groan came from Diesel as the shaft was pulled free from his tailhole, allowing the seed to leak out of him. Dylan then helped him up to his shaky feet and then helped him get properly clean with the water hose. Once they were both clear of any dirt they began to dry themselves off using some towels that had been hung out to dry on a clothesline. 

”Thanks for all of that, Dylan,” Diesel said with a smile. “It was great!”

”I’m glad you think so but don’t expect anything like that anytime soon because you’re grounded,” Dylan said firmly. Even if he did have a lot of fun he had told Diesel not to get dirty and they had both missed lunch because of him. Diesel looked a bit disappointed but then realized that he could later dig his way out of his room. He would just have to make sure Dylan wouldn’t notice…
