In this followup to Daddy Dog & Junior Dog's Birthday Bash, David and Josh travel out of the big city for their friend Jax's 50th Birthday. Since the old goat got his fancy van fixed up, the trio decide to spend a weekend in the wilderness for some good old-fashioned fun~


Ten Minutes Later…

The old goat nearly fell asleep in his inflatable chair, which was impressive given how pent-up he was getting just minutes beforehand. Even though he made sure not to shoot his load too soon, Jax was still hit with a strong wave of lethargy the moment David and Joshua finished their little romp. There was also a few minutes of awkwardness while the two Dobermen waited for Joshua’s knot to soften up, which meant they had to lie in place while still tied together. While Jax would’ve usually loved seeing a big brute like David getting unknotted, he ended up closing his eyes and dozing off while naked from the waist-down.

“NnnnNNNNGHHH!!” “Gahhhh!!~”

“Hmm-Wha? Wuzzat?” Jax may have overheard the two canines groaning hard in unison, but he didn’t jolt his head back up until it was too late. His eyes reopened when he heard a wet pop, which was quickly followed by David groaning deeply while hunched over the cooler. The goat turned his head just in time to see Joshua stumbling back, his face still red and sweaty after such an exhausting session. His knotted cock was still semi-flaccid, but now coated in a thick sheen of cum from base to tip. Meanwhile, Josh’s Dad couldn’t even stand back up while still sprawled with his hole visibly gaping.

“Ooh, nicely done!” Jax’s face lit up when he saw how stretched out Joshua left his Daddy. Not only was David’s hole stretched out with a generous amount of cum oozing out, but the ring could be seen winking hard without anything to fill it. Jax may have seen that reaction from the Doberman before, but that was years ago when he was closer to Joshua’s age. He ended up groaning in a mixture of admiration and slight envy, before glancing back at Joshua with a smirk. “Heh~ Hopefully I can get both of you gaping like that side-by-side someday…”

Joshua only took a second to look back at his Dad’s post-rutted state, and groaned through a bitten lip when he shivered and turned away. “Nnnnffffff… Fuck, that’d be a great video for the site~”

Jax cackled with a smug grin, and caught the flat huff he overheard from the older canine nearby. David took a breath before finally pulling himself off the cooler, but he still needed to stand bow-legged after his son’s enthusiastic knotting. He groaned through his teeth and pressed onto his lower-back with a paw when he stood upright. “Mmmmphhh… I might neeed to take a rain-check on that idea for now…”

Even when he got back to a standing position, David shivered when he felt the thick globs of his son’s cum trickling down the inside of his thighs. Josh and Jax couldn’t help glancing at the Doberman’s ass while his back was turned towards them, marveling at how well he was keeping his composure while gaped and leaking. Josh looked too stunned to speak, and could only blush while staring with a flustered smirk. Meanwhile, Jax’s cock was already twitching in aproval of the sight.

“Well, I can definitely say that it would have huge appeal. But for right now…” With a long and antsy groan, Jax kept a cocky grin as he looked between the father and son. After seeing all the fun David and Joshua shared, the old goat was eager to get back in the game before his birthday was up. “Mmmmmm… Just to clarify, are both of you good for another load or two? Because I sure as shit can’t top tonight…”

David sighed and rolled his eyes, but kept a light smirk when he turned around and showed his semi-erect cock hanging from his sheath. “Damn, you really didn’t cum yet? Guess you don’t have many rounds left in the chamber, huh?~”

“Oh, piss off!” Jax waved his paw with a huff while his friend chuckled all smug. He pointed a digit at him and said, “Just wait till you’re MY age, ‘Daddy Dog’. You’ll be lucky to still piss right after twelve more years.”

That remark just made Joshua scoff and roll his eyes. “Oh, please! I’ve recorded those vids myself, Jax. You do that just fine~”

David shuddered a little from his son’s enthusiastic tone. He knew that Josh could be a freak sometimes, but sometimes he worried the teen was kinkier than him. Jax just chuckled over at the younger Doberman, catching his attention with a couple perks of his brows. “Well, in that case, would you be okay with taking a seat somewhere… comfortable?~”

With the way Jax’s grin widened, Joshua was actually taken aback like he was given a pop-quiz question. He looked around all wide-eyed, unsure of what the goat meant by ‘comfortable’ in this context. However, considering the fact that he was still butt-naked out in the middle of nowhere, his options weren’t too varied. In the end, Joshua decided on a black metal lawn-chair, which luckily had some waterproof cushions strapped to the frame with velcro for a comfier sit. Even though the arm-rests on the sides were welded into place, the additional padding from the cushions lifted Josh enough so his waist -- and more importantly, his candy-red cock -- were higher than the bars and open for room.

“Whoo~ Already, son?” David scoffed while shooting Joshua a baffled-looking smirk of respect. “Jeeze, you’re making me show my age. Give me a couple minutes at least…”

“Ehh, it’s alright,” noted Jax with a shrug. “I’m probably gonna need one of you in me first before I can take the second knot~”

David and Josh looked back at the goat wide-eyed, just in time to see him stand up in all his pantsless glory. The fat, hairy brute was carrying a girthy beast of an uncut cock, which stood rigid with the entire length dangling back and forth. His gut hung low over his waist, while the thick tufts of fur trailing up towards his chest were matted with sweat and remnant loads. He peeled the ratty t-shirt off his torso, which by that point was damp enough from sweat to splat on the ground nearby. Even though he needed to take a moment to lean back with his palms against his lower-back, he groaned in satisfaction when he got a good crack from that stretch. “Nnnghh!!~ Alright then, I think I’m ready if you are…”

Joshua blushed more heavily, but kept an eager smile while staying put in his seat. David stepped aside with a smirk, watching as his friend came up with his erect cock bobbing around like a blind guy’s cane. Jax’s grin widened when he got in front of Josh’s chair, towering over him enough for the campfire to help cast a shadow over the young pup.

“Heh heh…” Despite his feeble expression, Josh pulled his arms away from the chair’s armrests so Jax could have enough room. “Well, uhhhh… go right ahead, Step-Daddy~”

The old goat shuddered with an antsy grin, nodding in approval. “Ahhh, that’s more like it! Now then…”

Jax wanted to remain confident when he got himself into position, but his first big stretch was enough to make him grimace in pain. Fortunately, as soon as Jax lifted up one of his legs over the chair, David quickly got in from behind to provide additional support. The goat huffed with a blushed, but gracious nod as he continued forward, accepting David’s help without much hesitancy. The older Doberman groaned when he hoisted Jax up from beneath his sweaty pits, biefly allowing the second leg to lift forward and get over the armrest. Before Joshua could try holding out his arms to assist, Jax’s burly form was pressed up tightly against him when he got atop his lap.

“HRMMMPHHH!! Nnnffffff…” Josh wasn’t uncomfortable by any means, but he certainly needed a moment to adjust to so much musky weight being brought down on him at once. It felt like he had a weighted blanket tossed on top of him, which had previously been used as a dog bed for at least a week. The ripe scent of sweat and sex-addled musk hit Josh’s senses like a brick, causing his eyes to roll back and the lids to flutter. He tried to let out a startled moan, but his voice was muffled when his muzzle got caught between the goat’s sweaty pecs. It certainly didn’t help when the underside of Josh’s cock brushed up tightly against Jax’s heavy gut, pressing in hard enough to make him throb against all that fur and fat.

“Mmmmmm… you comfy down there, kiddo?~” With David holding onto his back for leverage, Jax slowly settled on top of the chair to get in a suitable position. Fortunately, his legs didn’t feel much discomfort while braced up against the armrests, and the chair was sturdy enough to hold all that extra weight. He looked down at Joshua with a warm smile, which remained after seeing the canine nod his head flusteredly.

“Mmhmm~” Josh had to close his eyes in an attempt to try and maintain himself before penetration. However, he immediately realized his mistake the moment he took a deep breath through his nostrils. His eyes shot wide-open, and his entire body tensed up like he was hit with some sort of electrical surge. With Jax’s gut so close to his snout, Josh was hit with a strong dose of the goat’s musk that struck him faster than a bong hit. The ripe, unwashed stench hit his senses full-force, and his eyes rolled back before letting out a deep moan. Of course, his voice was fairly muffled when Jax leaned himself in, pressing Joshua’s muzzle between his sweaty moobs. “MMMPHHH!~”

“Yeah, there we go~” Jax licked his lips with a widening smirk, and took a moment to appreciate Joshua’s motorboating before lifting himself up. His fat belly brushed harder against the canine’s cock, causing Josh to groan more deeply between Jax’s moobs. With the help of David’s paws pressing into his back, Jax was able to nestle in closer against Joshua’s torso. And when he lifted his big ass over Josh’s crotch, Jax felt his buddy’s paws quickly moving downward. “Mmmffff~ You alright back there?”

“Yeah, I’m just helping…” David got a great view of the action behind Jax, and was able to see the goat’s musky hole hovering a few inches over Josh’s cock. His paws squeezed both of Jax’s hairy cheeks, and he spread them wide apart to show more of that pink pucker. David couldn’t resist leaning in between Jax and Josh’s bodies, and took a big whiff of their combined scents in such a tight place. “Nnnnnfffffff… Fuck, he’s a lucky boy down there.”

“Hey, I’m supposed to be the lucky boy!” Jax chuckled while glancing back at the Doberman. “Hmph~ You gonna sit there sniffin’ my ass all night, or are you gonna help me fill it?”

David pulled his muzzle back with a light smirk, and tightened his grip on Jax’s cheeks. “Yeah, don’t you worry, birthday boy! Lemme just get something here…”

Without warning, David pushed his head back in, and he opened his muzzle wide with hs tongue sticking out. Jax gasped with his brows raised, and his eyes clenched while letting out a shivering moan. Meanwhile, David closed his eyes more naturally as he dug in tongue-first, groaning from that first hard drag of his muscle up Jax’s hole.

“MMMMGGHHH… Ooohhhhh, fuck!~” Jax’s muzzle opened up wider, and his legs trembled against the chair’s frame from his fraying nerves. His musky hole clenched and puckered against David’s tongue, which drove the canine deeper into his own arousal. David’s cock was slipping from his sheath, with his fat knot coming out with a fleshy pop. Meanwhile, his son’s cock was already rock-hard while feeling the heat of Jax’s musky ass radiating against his flaring head. Unfortunately, Joshua wasn’t able to see his Dad eating Jax’s ass from his current spot, and could only hear his muffled and ravenous slurps.

David spent about a minute rimming Jax’s ass, although it may have been more for his own pleasure than the goat’s. His voice came out in a ravenous growl between Jax’s cheeks, which made his voice reverbrate quite well against that sensitive hole. Jax had to bite his bottom lip to keep himself from shooting prematurely, but a couple thick spurts of his precum still splattered all over Joshua’s chest. Through his groaning voice, Jax had to speak up before David could get too eager back there. “Mmmffff… That tongue’s nice, but I’d rather get some real cocks in there~”

David huffed to himself silently with an eye-roll, and gave a couple more tenative laps to that hole before pulling his muzzle back. He smirked while wiping his lips with the back of his forearm. “Heh~ You’d think with getting older you’d become a little less of a slut.”

“Eh, modesty is for chumps! I’d rather die an old slut than live as a fuckin’ prude…” Jax lifted himself up for a moment, allowing David to get a good look at the goat’s hole shimmering in a fresh coat of saliva. Of course, David used the opportunity to unbend his knees, and get back to standing while holding onto Jax’s backside. Meanwhile, the goat turned his head to ask, “Hey, uhhh… you mind helping guide it in for me? It’s hard to bend down and get it from this angle.”

“Yeah, no problem~” David leaned in and kissed Jax on the cheek, causing the old goat to groan and wipe his face with a grimace. The canine then reached down under Jax’s musky ass, and he caused his son to gasp when his paw wrapped around the base of his shaft.

“OoooOOOHHH!! Nffff, D-Dad…”

David couldn’t resist giving that slender, but lengthy cock a couple hard strokes in his paw, feeling how sharply it throbbed against his leathery pads. Josh couldn’t do much while pinned beneath all of Jax’s weight, especially when that sweaty gut was blocking his view of his Dad. Still, he reeled with his toes curling up tightly, and he savored every tantalizing stroke of David’s paw as he got Josh’s cock in a better position. “Mmmmphhhhh…”

“Therrrrreeeee we go…” David grinned when he got his son’s cock pointed directly upward, with Jax’s musky hole puckering mere inches above the head. He gave a quick tap to let Jax know he was good, and then watched as the goat slowly lowered himself with a deep sigh. Jax moaned out the moment he felt that pointed head prodding at his entrance, elliciting a wet squish from all of David’s drool coating the hole. While David and Jax groaned at the same time from that satisfying moment of contact, Joshua’s voice overpowered both of them when he belted out a shrill moan of his own.

“OOOHHHH!!~ Aaaaahhhhh…” Joshua clenched his eyes shut, but he didn’t hesitate when it came to getting that thick goat cock inside of him. His Dad’s rimming seemed to have worked out, since the teen could feel the warmth and wetness of that tight pucker wrapping around his head. There wasn’t too much resistance though, as Jax only needed a good push to get himself penetrated. As soon as Josh slipped in with a wet pop, both he and Jax moaned in unison while the teen’s shaft throbbed intensely. From behind, David grinned when he got a good look at his friend’s hole clenching around that veiny shaft.

“Fuuuuckkk…” David licked his lips, and he tightened his grip on Jax’s hips to help push him down even more. He groaned through his teeth when he saw the goat’s hole stretching out around his son’s girth, sliding down a few inches without much resistance. Jax clenched his eyes shut with a deeper moan escaping his muzzle, and his nerves tingled from the distinct twitches he could feel from Josh’s member inside of him. With David’s assistance, it didn’t take long before Jax slid down the teen’s whole length. “Therrrrreeee we go… Yeah, take that knot~”

Joshua’s knot was already beginning to swell out as his arousal intensified, causing him to throb and shoot more precum straight inside of Jax. David couldn’t resist leaning in once more, this time using his tongue for his son’s benefit. He closed his eyes with another hungry groan, right before making Joshua gasp when he dragged his tongue around his son’s knot. He drooled all over that fleshy bulb, while his snout rubbed up against Jax’s ass to keep him titillated as well.

“Ooh! Nnnfffff…” Josh trembled under Jax’s weight, and his eyes closed with a strong shudder when he felt the goat’s hot breath hitting his face. Jax was up so close against him, all the teen could smell was all that unwashed sweat and musk overwhelming his senses. He didn’t want to breathe in too deeply, just in case it set him off too soon inside of Jax’s hole. Fortunately, even with how pinned and restrained he may have been, Joshua was able to hold his composure long enough to feel that distinct pressure wrapping around his knot. “Ooohh! OOHHHH!~”

With another fleshy pop, Joshua and Jax moaned out when David finally got the knot inside. Jax’s voice came out much louder than his step-son’s, especially when Josh’s moan faltered in surprise. A couple thick strands of Jax’s load spurted out from that satisfying pop, landing across Josh’s face to leave a small facial. Jax didn’t hesitate to lean in with his muzzle drooling, and he made Joshua shiver when he dragged his tongue across the teen’s face. The old goat made sure to lick up every glob he bukkaked on the pup, but he didn’t swallow; instead, he just grinned down at him with his lips closed, and his eyes narrowing on Josh knowingly…

“Mmffff~” The instant he looked up and saw Jax’s face, Joshua lunged in before the goat could say a word. He planted his lips against Jax’s, and clenched his eyes shut when he felt his mouth open in response. A thick volley of Jax’s cum and drool filled the teen’s mouth, but he continued to make out with his Step-Daddy without complaint. Their rabid kissing lasted long enough for Josh to swallow up all of the goat’s load, much to Jax’s satisfation when he finaly pulled back.

“Hmph~ Such a good little slut you are…” Jax took a moment to close his eyes and sigh in contentment, loving the sansation of that young knot swelling and twitching inside of him. A couple decades ago, Jax would’ve likely been satisfied with just that cock alone; however, even with Joshua’s suitable girth, the old goat knew he needed more for his sloppy hole. That was when he turned his head glancing back at the canine, just as David was standing back upright. “So… You think you can handle a little close-contact?~”

“Well, if I couldn’t, I’d be a really crappy porn-star, now wouldn’t I…” David was grinning just as eagerly as Jax, especially when he was at the perfect position to join in from behind. Jax’s ass was perfectly level with David’s cock when he was standing, even with Josh’s cock buried firmly inside. Even though that musky pucker looked to be holding Josh securely, David knew his cum-dump of a friend long enough to know he wasn’t done. After spitting into his paw so he could give his cock a quick re-lubing, he got up behind Jax and wrapped his arms around his chest. “Mmmmmm… You’re handling my son’s cock really well, big guy~”

“Hey, you were the one who taught him so well…” Jax smirked back at him, and sighed when he took a second to savor his friend’s warmth against his bare back. Speaking of which, David didn’t hesitate to lean his hips in while still hugging Jax, and he caught both guys’ attention when he prodded that entrance with his cockhead. Jax and Josh both took deep breaths in preparation, while David just smirked as he got himself in position.

“Alright, just a--Nnnfffff… J-Justamoment…” David groaned through his teeth as he pushed in harder, needing some focus while Jax’s hole was so packed already. Luckily, his pointed head was able to nestle in right next to the base of his son’s cock, providing a good angle to work himself inside Jax’s hole. It still took a good amount of concentration, and David spent a good twenty or thirty seconds working himself through. “Mmmph, god dammit… Aaahhhhh, there we go…”

David eventually sighed in relief when he felt his friend’s hole giving in first, and his cockhead was soon given a tight clench after slipping through. He could hear Joshua’s slutty moans underneath Jax, which just made David’s cock harder when he continued to push through. His cock was nestled up tightly against his son’s, basically frotting him inside the old goat’s ass. All the while, Jax was hanging his head low and taking that second cock like a champ as he moaned under his breath.

“Whoo! Mmmmfffffff… Fuck, this takes me back~” This may have not been the first time he took two cocks at once, but doing this at the age of fifty was much different than back in his twenties. The pain wasn’t nearly as intense as he previously remembered, but the tight pressure and joint body heat was leaving him breathing hard and sweating like a pig. David could only push himself in an inch or two at a time due to the tightness, but he made sure to work as well as he could under the circumstances.

“Oooohhhhh… Goddamn, you’re tight~” It as ironic saying something like that while being the second cock to slide inside of Jax, but it wasn’t exactly incorrect either. Even though Jax was undoubtedly loose in his old age, both of the Dobermen’s knotted cocks were able to fit inside nice and snug to pleasure everyone involved. Jax continued to groan out the more he got stuffed, all while David and Josh’s cocks throbbed hard against one another. Both of the canines tried to hold themselvves strong, but Jax could hear both of their strained grunts as they worked together to fill the goat up.

“NNNNGHHHH… Ohhhh fuck!~” By the time David’s cockhead was getting close to his son’s, Jax shuddered when he felt that second knot prodding outside of his waiting hole. Both of those thick, meaty shafts were twitching and throbbing between his cheeks, leaving his toes curling and his cock leaking like a broken faucet. Joshua’s chest and stomach were basically matted with the goat’s gooey strands, while Jax’s heavy gut just pressed up tighter against the teen’s face. While the younger Doberman reeled in his seat, Jax glanced back at the one behind him with a sly huff. “Hmph~ You better not pull out once you get it in there…”

David shot a randy grin right back at him with a nod. “Believe me, the last thing I would do is pull out on the Birthday Slut. We’ll fill you up good~”

With that, David took another breath before doubling-down on his pushing. His fat knot pressed up tighter against the already stuffed entrance, hitting hard enough to make Jax and Josh moan at the same time. David’s knot continued to press in, until that hole finally began to yawn out even more. The pucker stretched out little by little, until the old goat was biting his bottom lip and straining his eyes shut. “NNNNNFFFFFF… Hmmmphhh, comeoncomeoncomeoncomeon…”

David kept working himself in, but his knot was nothing short of relentless. Jax’s hole continued to stretch out even more, until it got around the girthiest part of that knot. As soon as it passed, David only needed a single thrust to push himself through and firmly knot the goat alongside his son. Of course, all three of them moaned out due to how tight and titillating it was all around. “NnnnNNNNNnnnnghhhhh…”

For about a minute, none of the three did much while pinned in such a precariously hot pose. Jax couldn’t stop moaning with every shaky breath that came out of his mouth, all while his cock twitched and spasmed over Joshua’s torso. Of course, when David gave another thrust to push himself inside even deeper, that was when Jax gasped and tensed up between them. “Mmmphhh!! Aww, fuck! Nnnnnghhhhh…”

With both of those thick knotted cocks packed so tightly inside of him, there was no doubt that they’d cause some internal distress. Joshua’s cock was already pressing up snug against Jax’s prostate, but David’s pressed up against another sensitive region that cuased a similar stirring between the goat’s legs. When David and Joshua both got balls-deep inside of him, Jax let out a deep, moaning sigh before it happened. “Aaaaaaahhhhhhh…”

“Ooohh!!~” Joshua was halfway lost in his lustful high before the acrid scent of piss caught his senses. His eyes reopened just in time to see a thin stream of urine shooting out of Jax’s cock, most likely from his bladder being under so much pressure. A couple spurts of piss shot out before Jax tried to stop himself, clecnhing his cheeks hard on both canines’ cocks. However, even after David and Josh winced from the sudden tightness, the latter was blushing hard while looking up at Jax with a bitten lip. “Mmmmmm… N-Not bad, Step-Daddy~”

Jax raised a brow and looked down at him, seeing the feeble smile that Joshua was trying to show behind his blush. It didn’t take long for the goat to know what that look meant, as well as what may have caused it. It took a moment before he could try relaxing his hole again, but it gave him just enough time to reach down and grab his cock with a paw. His grin was matched by Josh’s, who was able to nod his head before the goat could even ask permission first. Because of that, Jax closed his eyes and sighed before letting the floodgates open. “Aaaahhhhhh~”

A much stronger torrent of hot, fresh piss came out while Jax’s muzzle hung open. Joshua moaned out and closed his eyes, tensing up when he felt the pee hitting his chest. Jax’s grin widened while he emptied his bladder, making sure to aim and move his stream around to cover as much of Josh’s fur as he could. His chest, stomach, shoulders, and even his face were hit with the ripe stream that sprayed out powerfully. The teen moaned out with several hard throbs inside of him, absolutely loving the sensation of his fur being soaked in so much musky warmth.

“Ugh, for crying out loud…” David only needed to take a couple sniffs to catch the stench of Jax’s piss, but he tried biting his tongue while rolling his eyes. “Jeeze, you two are fuckin’ nasty…”

“Fuck yeah we are!” Jax just cackled with a gloating smile after finishing, leaving Joshua totally matted from head to stomach. The pup was shivering a little with an antsy moan through his bitten lip, but he looked just as satisfied as Jax after that golden shower. His nostrils flared out to take a deep breath, and he ended up shuddering through his gritted teeth while grinning wide. His shaft pulsated deep inside of Jax, with David also able to feel those distinct throbs against his own. Both he and Jax tensed up as they groaned and clung to each other in tighter embrace. “Nnnnfffff… Goddamn, you two are dense, holy shit!~”

Both of those thick, meaty knots were firmly packed inside the old goat, stretching out his hole as it direly tried to grip both bases at once. If it wasn’t for his fat gut, there was a chance that the bulges of Josh and David’s cocks would’ve been seen protruding from his lower stomach. But with the father & son’s balls tightly nestled up against one another, there was no doubt that it was a mercilessly tight fit.

“Hrnnnphhh… Whoo!~” David was the first to breathe out in an expasperated huff, all while keeping a cheeky smirk. “Got-damn! You’re still full of surprises in your age, huh?~”

“Mmmmphhh… S-Says the guy frotting his own kid in my ass. Ahhh!!~” Jax tensed up and gave another hard squeeze to both canines’ knots at the same time. David and Josh moaned and throbbed inside the goat, hitting his prostate hard enough for more precum to splatter across the teen’s piss-soaked chest. Jax threw his head down with his eyes clenched shut, needing a second to keep his bearings in check. But as soon as he breathed out in a raspy moan, Jax threw his head back up with a more confident grin. “Nnnffff!! Alright, boys! You better keep a good grip, ‘cause I’m not stopping until I feel both your loads~”

David huffed with a cocky smirk of his own, but he could’ve sworn he heard his son make the same response from Jax’s other side. That idea seemed more feasible when David throbbed inside of the goat’s clenching hole, right at the same time he felt some strong pulsations from Joshua’s shaft as well. Both of them knew that things could easily go really well, or really badly depending on how effectively they’re able to work together. Luckily, despite how heavy Jax may have been, David had a sturdy grip on his thighs as he got himself in position. “Mmmph, alright, alright… I’m gonna start thrusting first. You ready down there, Josh?”

“Mmhm!~” The teenager nodded his head with an antsy smirk, all while looking up at Jax with his eyes narrowing in determination. “I’ll be ready when you are, Daddy! Anything for… Step-Daddy~”

That was enough to make Jax lean in and plant his muzzle against Josh’s for a deep kiss. The two closed their eyes and made out with both their tongues in play, and their nostrils flaring to breathe in all that concentrated musk lingering in the air. As their lips meshed and smacked all sloppily, trickling drool down their chins to add the mess on Josh’s chest, David just shook his head with a playful scoff. “Hmph~ Well, allow me to start things off…”

David groaned harshly through his teeth, and yanked back hard with a good amount of strength through his hips. Jax’s head yanked back to let out a sharp howl, and his hole contracted to better tug on Daddy Dog’s fat knot. Joshua also moaned out as he felt his Dad’s knot grinding against his shaft. David was only able to pull back a few inches at most, but it was more than enough to sate Jax’s cravings as his hole was given such an intense yanking. Josh may have been taken aback at first, but he was able to get himself breathing correctly in anticipation for what was to come. “Oof… Heh, w-way to start teasing that hole without me, Dad~”

“Well, you got a perfectly fine pair of hips on ya! Get your ass into it and fuck your Step-Daddy’s!”

Jax cackled in perverted delight with his eyes rolled back, but it was cut off midway with a heated groan when David gave another hard tug. His knot wasn’t able to slip back out as easily as it went in, especially when his son began to piston his hips back as well. The sheer girth of both the canines’ cocks was enough to stretch out Jax to an absurd degree; of course, when David and Jax both pulled back enough for their knots to pull against Jax’s hole at the same time, the goat’s back arched inward like he was hit with a sudden demonic possession. “HRMPHHH!! Aaahhh!! AAAHHHH!!~”

Several more spurts of Jax’s precum spat out wildly from that tantalizing tug of both their knots, draping his seed all across the back of Joshua’s head. Meanwhile, the teen barely noticed the additional strands while his eyes and teeth were tightly clenched shut. Both he and his Dad were working with strenuous grimaces on their faces, while their hips yanked back only a few inches at a time. Neither of their knots were able to slip out of Jax’s musky ass, but they were certainly trying their best as they left the goat reeling between them in uninhibited ecstasy.

“HOOO!!! Mmmmphhh… Fuck, you guys sure know how to wrap those gifts of yours nice and tight…” Jax winced as he took that moment to squeeze his hole with that last emphasized word. David and Josh groaned with their faces tightening at the same time, while Jax hugged both of their cocks relentlessly tight for a few seconds. However, even when Jax “relaxed” himself following the contraction of his muscles, his hole was still clinging around their shared girths mercilessly.

“GAH!! Nnnnffff… Fuck, you’re tighter than guys half your age!” Joshua may have meannt that genuinely with a clenching face, but Jax and David still laughed with the goat smirking down at him all coy.

“What, I’m ‘tight’ now? I litrally have TWO knotted cocks in my ass, that’s more loose than a prison snitch~”

David huffed and was quick to reply, “Yeah, but they’re not nearly as fun as an old slut like you~”

“Dawww, c’mere you…” Jax yanked him in with a free arm, and leaned his head back enough to plant his lips on David’s muzzle. Despite the slight surprise, the canine immediately reciprocated and made out with him with his eyes contently closed. Kissing Jax was of no issue to him, and he just savored the moment while yanking back his hips a couple times. It was enough to make Jax’s voice groan and hiccup while still connecting his lips to Josh’s Daddy’s. “MmmmMMPHH! Mmmm…. Nnnfff~”

Their lips soon broke apart with a wet pop, replaced with a hungrier moan as Jax felt those tugs from their knots more brutally. Joshua was picking up the pace to catch up with his Dad, and managed to get Jax’s fur standing on end with a few hard pulls against the goat’s hole. Both he and David were making good work in stimulating that all for all it was worth, all while also frotting their throbbing lengths against one another. Even though neither of them could move too much while tied inside of Jax, their motions were titillating enough for both of them to feel how close they were getting regardless.

“Mmmfff!! H-How the fuck am I so close already?! Urrffff…” Joshua closed his eyes and tried controlling his breathing, but it did nothing to stop his cock from throbbing more intensely. Although, given how constantly Jax’s fat and musky gut was pressing up against his face, his senses were overwhelmed enough to leave him teetering at the brink for a while. His face was already as red as his and his Dad’s knots, and sweat was beading across his brow from the continuous strain of Jax’s musk and weight pressing down on him. But even as his muscles began to sense up, Josh kept pumping his hips back and forth so he could tug on that goat’s hole alongside his Dad. “Ohhhh yeah… I can’t wait to breed my Stepdad~”

It was fortunate that Josh and Jax weren’t able to see how much David rolled his eyes from that remark. The two continued to pound Jax’s hole in incestuous tendem, straining that ring each time their knots pulled against it from the inside. David’s face was visibly less frazzled than his son, but his cheeks were equally as red as his arousal was intensifying on top of that sweaty goat sandwich. Both of the Dobermen’s cocks were throbbing like crazy inside of Jax, pumping more precum inside of him while their knots plugged up the only means of escape. Jax wasn’t sure which one was grinding up against his prostate, but whoever it was was leaving him in spellbinding bliss with his eyes rolled back behind the lids.

“Aaaahhhhh!!! NnnnNNNFFF…” His teeth gritted tightly as his cock twitched as much as his trembling limbs. His hole couldn’t keep squeezing when their knots were pistoning back and forth at such a furious pace, putting his ass through a brutal barrage of tugs and grinds that left his nerves reeling like crazy. It wasn’t until he belted out one last slutty moan that he was able to take a deep enough breath and speak wholeheartedly. “Aaahh! AHHH!! Mnnnghhh… B-B-Breed my fuckin’ hole you goddamn pussies!!”

That actually seemed to do the trick, at least for Joshua as his legs writhed underneath Jax’s weight. He tried to pull his head back and let out a deep moan of his own, but his eyes shot wide-open the instant he tried taking a deep breath through his open mouth. Not only did he end up sucking a deep breath of Jax’s musk and remnant piss, nestled right in that sweaty tuft of chest-hair between his fat moobs, but his muzzle was promptly pinned against that chest midway through his moan. His eyes rolled back enough to only show the whites, and his whole body convulsed from that onslaught of sensual bombardment as he was hit with an immediate response. “MMMMMPHHHH!!!~”

Joshua’s body spasmed hard in the chair, and David gasped when he felt how sharply his son’s cock was throbbing against his own. Those pulsations against his shaft were accompanied with a sudden sensation of wet, gushing warmth that made the older canine’s body shiver antsily. Of course, Jax’s body quivered harder than either of the Dobermen in his embrace, and they were able to feel every muscle in his body tensing up all at once. “Ooohhh!! OOOHHHH!!!~”

“GNNNNN!!!” Joshua kept cumming uncontrollably, but he was helplessly pinned under Jax’s fat gut while flooding his ass with so much spunk. Each thick rope blasted out to shoot into Jax’s deepest depths, hitting that prostate and making the goat’s ankles curl up tightly. David’s knees nearly buckled from the titillation that came with feeling his son’s orgasm in such a direct -- and somehow also indirect -- way. Josh wasn’t even finished unloading before David let out a hoarse cry of his own.

“GAHHH!! Nnnnghhhh, aww, SHIT!!~” David’s hips pounded into that fat ass with a furious barrage of last-minute thrusts, which made his balls repeatedly smack against his son’s slightly heavier pair. While he plowed the old goat like a broken jackhammer, his cock throbbed just as strongly as Josh’s as they briefly orgasmed in unison. Both of their thick, knotted lengths continued to batter the inside of Jax’s hole, all while their shared loads filled more of the birthday boy’s insides.

“AaaaaAAAHHHH!!~” Jax was absolutely reeling in euphoric pleasure, and his arousal couldn’t take any more after that second cumshot inside of him. The sensation of Father and Son frotting together in his burly ass, not to mention the indescribably intense feeling of two guys unloading bareback inside, was enough to make him feel like he was floating on air and pure electricity. His nerves all writhed and tingled at the same time, just as his back spasmed hard enough to make him march back between the two studs. “Gah, aww fuck! Aaaawwwwww FFFFUUUUCCCKKKK!!!~”

Joshua and David were still pounding his ass with the last of their joint strength, and the sheer volume of their loads was immense when Jax’s hole was so tightly plugged. With no place else to go, all of the Dobermen’s loads just filled up inside the goat, bloating out his belly even more than it was already. However, even with the Father and Son able to hold in any leakage, the same couldn’t be said for Jax when he freely shot his load all over the place.

“Aaahhh!! AAAHHH!! MMMMmmmmmm…” Jax’s eyes clenched shut while he breathed shakily through his nostrils, all while his cock spasmed wildly against Joshua’s bare chest. Even though the younger canine was already drizzled in quite a bit of precum, it was nothing compared to the thick spurts that erupted from Jax’s fat cock. Rope after rope shot out to land all across Joshua’s chest and face, catching him off-guard well enough to make him open his muzzle. And when that first strand of Jax’s cum landed across the teenager’s tongue, Joshua just moaned out and opened his slutty mouth even more.

“Aaahhhh!!~” Joshua opened his eyes quickly enough to see how close Jax’s cock was to his face, pulling him from any post-orgasmic state of lethargy before it could begin. Still reeling in primal lust, Josh reached out with a free paw and managed to grab hold of Jax’s twitching member. While the goat gasped and moaned even deeper, the teen furiously tugged on that girthy beast while aiming it straight at his face. “Oh god, yes!!~”

Without thinking, Joshua closed his eyes and opened his mouth nice and wide for his Step-Daddy’s load. Luckily for the slutty pup, Jax had several more ropes in him as he unloaded right between those inviting lips. Joshua quivered with his fur standing on end, but his arm was rigorously jerking off the goat without apprehension. By the time Jax finally finished cumming -- notably longer than the Father and Son’s shared loads that were currently settling inside of him -- Joshua was struggling to breathe through his nostrils while his mouth was wide-open and full to the brim with Jax’s spunk.

“Aaaaahhhhhh… Aaahh~” It may have taken Jax a bit longer than expected, but he eventually sighed in contentment after unloading every drop he had. David and Josh were still hard enough for their knots to remain nice and swollen, but the two were already coming down from such an intense and lustful high. Jax nearly suffocated Josh as he laid on top of him more lazily, unable to hold himself upright while carrying what felt like a liter of cum sloshing inside. Fortunately for both of them, even with David finishing just as thoughly as the others, he was able to hold himself upright and keep a steady grip.

“Mmmmphh… Oooohhhhhh, fuck you for being so fuckin’ fat…” His head lurched down with a couple rapid pants, and he had to widen his stance so he could remain upright. However, it still took a bit of effort to keep himself in a somewhat-comfortable stance when his knot was firmly tied inside Jax’s ass. He had to try and hoist him up by his thighs to get him better nestled against his waist; unfortunately, that caused Josh to be yanked up by his dick.

“AHH! AHH!!” The teenager squirmed underneath Jax’s sweaty body, causing the goat to laugh tiredly when he saw how much he was struggling. “D-DAD! Lemme down! LEMME DOWN!”

“Aww, shit! Daddy literally got you by the balls, huh?! HA HA HA HAAAA!!!~”

“Nnnnghhh!! H-He has me by my DICK! GAH!” Josh tried to move his hips while suspended a couple inches off the chair. A couple hard nudges was enough to jolt Jax out of his cackling when his hole was tugged under Josh’s weight.

“OOH! Mmmffffff…” Jax shuddered and bit his bottom lip with a heated groan. “Nnnghhh… A-Actually, I’m with Josh! Lower us in the damn chair!”

“Just a sec! Aaaahhhh…” David had to get himself in a semi-squat, but he managed to make all three of them sigh at the same time when Josh was settled back in the chair. The trio were still connected out in the middle of nowhere, with only the nature around them to witness such a perverted sight beneath the evening skies. With the campfire crackling nearby, the only other noises to break through the silence were the heavy breaths from all three of the post-coital mates.

“Whoooooo… Ohhhhh fuck~” Even though he was still packed with two knotted cocks, Jax was able to relax between both of the spent canines. “Mmmmm… Okay, I’m calling it now. That’s the best birthday gift I’ve ever received~”

Both David and Josh chortled at the same time, their voices nearly as identical as their smirks. Even with how overwhelmed both of them felt following their orgasms, David was the first to speak up in response. “Heh~ Oh, really now? So… does that mean I can keep the stand-mixer I was gonna give you as a backup gift?”

Jax’s face lit up with an excited gasp. “You got me a stand-mixer?!”

The End
