Kane and Kyle, two german shepherds, father and son respectively, drove over to a friend’s house in a special neighborhood that they moved into recently, mostly due to it being pretty cheap to live there, both father (37) and son (14) were pretty buff, in fact, they were very muscular and huge in comparison to most, even Kyle despite his age, big arms and biceps, wide chests, plump pecs, perky nipples that pushed against their clothes pretty visibly, just two, huge bodies sitting in a big ass truck.

Kane earned his body from years of high school and college wrestling, religious gym visits and strict regime, as well as the many years as a policeman, now Chief of the local station. Meanwhile, Kyle’s was due to his father’s influence mostly, followed by years of bodybuilding from a very young age, plus his father’s very generous genes. The only difference between them -body-wise- was their height.

The neighborhood was males only, so no women or girls in sight, and that suited the two dogs just fine, they drove past one of their neighbors, a middle-aged horse, who was completely nude, his massive and powerful body on full display for all to see, his huge horse cock in hand and jerking away so casually. They stopped at a traffic light and noticed him, Kane letting out a shrill whistle to get his attention, just as Kyle lifted himself up to his knees on his seat, turning to the window and lifting his t-shirt, revealing the beautiful row of hard abs and huge pecs, flexing and bouncing them for the horse, goofily poking his tongue out as he shamelessly pinched and rubbed at his fat nipples, his large junk bulge drooping slightly outside the window.

Just as the light turned green and they began driving away, both dogs heard a loud and unmistakable whinny as the horse busted a huge load all over his patio, both shepherds sharing a smug look and a fist-bump.

They arrived at the house they were looking for, Kyle practically jumped out of the car and raced over to the door, giving it three quick knocks as Kane was rummaging around in the back of his truck. The door soon opened to reveal a tall and slim-fit dalmatian around Kane’s age, wearing a fancy, bright colored shirt and dark suit pants, small, rectangular glasses sitting on his snout, he looked down to see the muscular pup grinning up at him goofily “Oh hey, Kane! You guys sure are early”

Just then, a younger dalmatian, slightly younger than Kyle came up from behind his dad, wearing a black tank top, dark green gym shorts, and a red cap backward on his head, his round glasses briefly reflecting the sunlight “Kyle!” He barked in excitement as he glomped the GS pup. They dalmatian pup had a pretty buff build himself, but he wasn’t as big and bulky as Kyle was, but he was close enough.

“Hey, Vinny. Good to see you keeping up with your weights” Kyle said as he rubbed the other pup’s chest lovingly, checking his recent gains and just wanting to touch his friend as much as possible

Kane placed a duffel bag beside Kyle “Hey, Bruce. Figured we’d get started early” He had a toothy grin on his face, fangs bared in a slightly menacing manner as he addressed the older dalmatian, Bruce’s face flashing red as he pulled on his shirt’s collar, a nervous but excited expression on his face as he knew what the older shepard was hinting at. Kane stepped closer, his body inches from pressing against Bruce’s, looking down at the shorter canine, while Kane was this massive and wide wall of muscle Bruce was more along the lines of lean and athletic, his body filled his clothes nicely, but didn’t stretch them to the very limit like Kane did his own.

“Uhm… b-boys? Ho-How about you go in and enjoy yourself while us adults t-talk?” Bruce stuttered out his words just as Kane’s hands reached around to grope at his ass, hard, forcing a small moan out of him.

“Yeah… ‘talk’~” Kane’s voice dropped to an almost growly tone, his hand grabbing and groping at the dalmatian’s ass.

“We better leave them to it. Come on, I’ll show you to my room~” Vinny pulled Kyle in as the younger german shepard grabbed his duffel bag, closing the door behind them.

Not even a second later *BAM* “AH! Kyle, wait! T-The neighbors, they’re gon- AHN~!” This was followed by the unmistakable sound of hard, rough, animalistic sex as Bruce moaned and whined needily while Kane growled, huffed, and snarled like the beast in heat he was.

“Let’s give ‘em a fucking show, then! Maybe they’ll learn a thing or two!” Each one of Kane’s thrusts slammed Bruce hard against the door, just a constant string of *BANG BANG BANG BANG* one would think someone was knocking on the door with a battering ram.

“Sheesh, my condolences to your dad’s ass” Kyle laughed as he followed Vinny upstairs.

“Oh please, like you don’t do the same when you fuck me” The younger dalmatian snickered as he shook his ass at the other pup, his tail already hiked up and wagging. “Besides, my dad’s a well-known slut, he can handle it”

Kyle smirked as he gave Vinny’s plump ass a firm grope, getting a small moan out of the dalmatian “That’s because I know you like it rough. Can’t help it with that tasty ass in front of me” As they reached the dalmatian’s room and closed the door behind them “Speaking of dads, have you noticed how our dads are spending more time together?”

“Yeah, the ‘sneaky’ phone calls when they think we’re not listening, the brief outings together, the dinner dates, ‘secret’ messages” Vinny giggled as he listed the things he noticed his dad doing with Kyle’s own.

“They think they’re so slick. They should get married already, literally EVERYONE knows already for crying out loud” Kyle chuckled as he dropped his duffel bag and jumped on Vinny’s bed, taking a deep breath of the dalmatian’s scent covering the sheets.

“That would be awesome, honestly~” Vinny agreed as he crawled up the bed and plopped himself on top of Kyle’s larger body, like a body-pillow, nuzzling against the german shepard’s nape, taking small whiffs of his musk “Mmm, you smell so good, right now~” He pressed his nose against the middle of Kyle’s upper back and took a deeper breath of his scent.

“Knew how much you liked it, so I made sure to get some cardio and wright reps in before heading out with dad” Kyle chuckled as he felt Vinny’s nose and breath tickle his back.

“Come on, let’s head back down. Got some new games I wanted to show ya~!” Vinny excitedly jumped off of Kyle’s back and off the bed, followed closely by the shepard pup as they raced down the stairs, the banging on the door still loud and evident as Kane brutalized Bruce’s ass and insides further with his huge cock.

The boys just turned on the game console and started playing. Soon after, their dads walked in, Kane wearing a smug look on his face and strutting around like he owned the place, completely naked, while Bruce had a goofy, satisfied look on his face, limping slightly as his legs wobbled with each step, belly slightly bloated out as his front, crotch, and face were covered in cum, his ass leaking big time and leaving a snail trail wherever he walked.

The day was spent with all four canines spending as much time close to each other as possible, playing some family games, Kane almost breaking a controller as he kept losing all the time, teasing and groping each other, hugging, cuddling, and lots of homoerotic shenanigans of course. Just four dogs roughhousing and playing around with each other until dinner time came.
*****

That evening, after dinner, the four canines lounged in the living room, Bruce cuddling close to Kane and Vinny to Kyle, all were completely naked, their awesome and beautiful bodies on display as they watched some police drama on TV.

But their attention span didn’t last long on the TV as it soon turned to their respective, significant other.

Bruce gently rubbed at Kane’s pecs, groping them firmly before turning his attention briefly to the nipples, giving each a firm pinch and tug, earning him a lustful growl from the larger canine. Kane’s cock quickly responded by sliding out of his sheath, swiftly standing at full arousal at an amazing 18 inches, not counting the knot, Bruce’s hand quickly slid over Kane’s hard abs before grabbing onto that bulbous knot, getting a deeper growl from the german shepard. Bruce’s own 12 inches sliding out of his sheath and already throbbing and leaking with excitement, but it lay there forgotten as his attention was on the bigger canine.

“Hrrrr~ Better get to work quickly, babe, unless I start taking control~” He spoke in the deep and growly voice that Bruce loved, fangs bared in an intimidating manner that sent lovely shivers down the dalmatian’s spine. Bruce just gulped and went to work as order, giving Kane’s cock a few strokes before going down on it, taking the head and a few inches into his mouth and throat, no gag-reflex whatsoever, even when he took more and more of that cock in. “Grrrr~ There’s a good bitch… dinner wasn’t enough for ya, huh?” Kane chuckled throatily as he gave Bruce’s ass a hard *SMACK*.

The pups weren’t far behind, but they were a bit more… romantic and sensual than their dads. Their lips gently pressed against one another in a loving and warm kiss, one of Vinny’s arms wrapped around Kyle’s neck while the other was rubbing and groping at a pec, giving the nipple some attention as well, the younger shepard’s cock responding like his father’s did, swiftly growing out of his sheath to an impressive 10 inches, too big for a boy his age, that thing is gonna be a MONSTER once he’s older. Vinny’s own 6 inches felt tiny in comparison, but Kyle always told him that it was as beautiful as the rest of him.

Vinny then went down on Kyle, the shepard pup leaning back and spreading his legs to give the dalmatian more room as Vinny expertly swallowed every inch of Kyle’s cock, the shepard letting out a deep, growly moan as his eyes briefly crossed from the sensation, gently humping up into Vinny’s mouth.

The sounds of loud and shameless slurping and sucking filled the living room as each dalmatian serviced his respective german shepard, Kane and Kyle sharing a quick fist-pump like two college bros scoring some chicks for the night.

Then it was time for the main event. Both german shepherds remained seated as their respective dalmatian stood up in front of them, showing off their plump rumps and well-worked holes before slowly sitting down on the large cocks offered to them “OOooohhhnnnn~!” Bruce and Vinny moaned sluttily in unison as those cocks slid easily inside of them, proof of how used they are at taking cock, their hard abs eventually bulging out as they sat on those fat knots, bouncing on those cocks excitedly, rolling and grinding their hips firmly in the shepherds’ laps.

But it didn’t take long for the bigger dogs to take control as they flipped around while holding their respective dalmatian until they were facing the couch, doggy style, showing off how different in they are with their preferences in ‘lovemaking’.

Kane was a feral in a rut, full speed and steam ahead, huffing and growling like the mad beast he was, just *WHAM WHAM WHAM* right into Bruce’s insides, leaving Bruce screaming and howling in both pain and ecstasy, Kane’s large and strong hands groping and grabbing at the dalmatian’s pecs, pinching and pulling hard on his nipples, even giving them a firm twist, just generally being rough with his bitch, just like how Bruce liked it.

Kyle on the other hand was a bit less rough with Vinny, sure he was thrusting hard into him, really hard, but that was about it, his hand would rub at the younger dalmatian’s belly to feel his cock bulging out Vinny’s abs, while his other hand almost worshipped his pecs with how gentle and soft he was doing it, of course, there was the occasional pinch, twist, and pull, but he was being as rough as his father was with Vinny’s.

All four canines were sweating up a storm from such a marvelous workout, their fur was matted and messy, bodies glossy and shiny, and the smell of sweat and musk just filled the living room to the point that even the windows were slightly fogging up.

Then the climaxes came.

Both german shepherds grabbed their dalmatians in the perfect full-nelson, ramming their cocks hard and mercilessly into the smaller dogs as they growled and huffed, inching closer and closer to their orgasms, but Bruce and Vinny beat them to the punch as every sensitive and pleasurable button inside of them was pressed and punched, hard. Both dalmatians let out a weak howl as they sprayed the leather couch with their loads, painting a good portion of the dark colored piece of furniture white on either end.

Then it was Kane and Kyle’s turns, announcing their orgasms with loud, deep, triumphant roars, tightening their grip on their respective dalmatian as they slammed their knots right in, locking them together before pumping what felt like gallons worth of cum right into their bellies *GWURP GLUP PLURP GRROOWOP* Bruce’s and Vinny’s bellies quickly extended and bloated out, their well-cut abs quickly disappearing and smoothing out the more they were filled.

And just as suddenly as it ‘came’, everything went silent. Save for the panting of the four dogs trying to catch their breath. Once everyone calmed down they sat back down on the couch, neither german shepherd caring that it was coated in cum, in fact, they loved the sticky feeling on their back, despite knowing that getting up later will be a bitch.

They resumed watching whatever show came next, since the police drama ended ages ago, but once again, they weren’t focusing on it but on each other instead. Having busted his load that would make a horse jealous, Kane became a bit more docile, peppering Bruce’s face with gentle kisses and small licks of affection, one hand resting on the dalmatian’s bloated belly and the other on his thigh.

Kyle was doing the same to Vinny, both younger pups nuzzling their cheeks and snouts against one another as Kyle rubbed Vinny’s cum-filled belly, giving it the occasional wobble which got a small chuckle from the younger dalmatian, both enjoying hearing all that cum just *sloush slursh blurp glup* around.

But eventually it was bed time, the pups were allowed to stay up late since it was the weekend, but everyone became too tired to stay up further, no surprise after what just transpired, so both german shepherds effortlessly picked up his dalmatian, still knotted firmly inside, and walked up the stairs to Bruce and Vinny’s rooms, nothing more than some more nuzzle and kisses happened as both adults and pups were too tired for one more round, dozing off almost as soon as they laid on their beds.
*****

The next morning Kane woke up early to drive back to their home, promising to come back and pick up the other three for their weekend outing with some friends later. Bruce and Vinny quickly packed up some essentials as well then joined Kyle in the living room to wait for the older german shepherd to come back, killing time with some games until then.

Once Kane came back, now dressed in a shirt with floral patterns and shorts that showed off his strong and thick thighs, the back of the truck filled with some essentials they’ll need, Bruce climbed into the passenger seat while the boys climbed into the back. Kane quickly leaned in and placed a small kiss on Bruce’s cheek “If you think last night was fun, wait till we get to our destination. You two are gonna love it” He said the last part addressing both dalmatians before driving away.

“Man, one would get butterflies in their stomach, but it feels like I swallowed a swarm of bees.” Vinny said in a voice of both excitement and nerves.

Kyled hugged him close and gave the side of his muzzle a small smooch. “Nothing to worry about. Dad and I have been to uncle Mal’s place hundreds of times. Trust me, it’ll be fun, there will be others like us there, too!” He said the last part as he raised one arm and gave it a hard flex, slightly ripping the sleeve of his t-shirt “Whoops”

That got a chuckle from everyone in the car as they drove away toward a fun-filled weekend.
