Before that day, Spike had no idea what the Diamond Dogs’ “Breeding Bitch Room” would actually look like. Given how dingy and unclean the rest of the caves and mining systems looked like, the drake was sure that it was just some musky cave with a couple of stained mattresses on the floor. Heck, it could’ve even been a couple of stocks to keep females leashed up and present for every guy that came through (not that he would’ve minded, of course~). But as soon as Spike was lead to the expertly dug-out room, his eyes widened in pleasant surprise. It may have still been a cave with rock walls and no windows, but it was much different from the rest of the place.

For one thing, the room actually had a door, and a wall covering the cave entrance for privacy. And instead of raw dirt or grime under Spike's feet, the Breeding Bitch Room actually had a thick carpeting that covered the entire floor (along with several smaller rugs which he assumed were to cover up stains). The two beds in the room were admittedly bare (probably from the girls leaving with all the beddings), but they were also in somewhat decent bed-frames and looked to be fairly comfortable. The room even had its own personal bathroom with a shower and toiletries, which couldn’t have been easy to set up underground. Of course, as soon as the dragon stepped inside the surprisingly decent room, the shelf on the back wall was what caught his attention.

Specifically, the various toys and bondage items the Diamond Dogs had for their previous breeding bitches.

After making sure his associates and the other miners stayed outside for a moment, Rover stepped into the room to see what Spike thought of the place. “Just so you, we do have extra sheets and stuff. We just wanted to wait till we found a new girl to--OH!”

Rover wasn’t sure what he expected when Spike went into the Breeding Bitch Room by himself, but he became wide-eyed when he saw the drake already snapping a bright pink leash onto the front of his collar. Upon noticing the Diamond Dog, Spike paused with a small blush while holding his new addition. “What? I had to make sure it’s good quality.” The dragon gave the leash several hard yanks with his claw, smirking when he felt how secure the latch really was.

Rover just scoffed and asked with narrowed eyes. “Are you really questioning the quality of a leash from us? That’d be like if we questioned you on gem quality.”

Spike wanted to retort, but stopped himself while his mouth was still open. He then shrugged and replied, “You know what? You have a fair point there.”

“Damn right I do~” Rover carried a smirk as he leaned against the doorway with his arms crossed over his chest. He craned his neck towards one of the beds and added, “And just so you know, those frames are a good place to latch the other end of that leash to. Believe me, they’re sturdy~”

After a pert nod alongside his randy grin, Spike took Rover’s advice as he hopped up on the bare mattress. The drake expertly tied the other end of the leash to the metal head-bar, and gave it a good tug to make sure it wouldn’t break. Even though he knew his fire breath and claws would be more than enough to ensure he wasn’t really trapped, a small shiver crept up Spike’s spine from the idea of being in such a “vulnerable” state. That was when the dragon looked back with a sultry stare to Rover, and kept his claws on the bar as he stood in a braced position.

“So, Mister Diamond Dog,” purred Spike with a lick of his lips while his rear was pointed towards the doorway, his tail slowly lifting as it swayed back and fourth in a teasing manner. “How long are the shifts of your ‘Breeding Bitches,’ exactly?~”

Rover smirked wide at Spike’s presented figure, happy that the slut was rearing to go so shortly after taking three Diamond Dog cocks at once. “Well,” he replied with a small shrug, “they usually last about eight hours, but I have a feeling you should be back to your pony friends sooner than that.”

Despite the tempting offer to go a full “shift,” Spike knew that Rover wasn’t wrong. He promised to help Twilight with book organizing tonight, and he was wanting to cook her a nice risotto beforehand. After a small nod, Spike said with a shrug, “Well, I can take four hours pretty well. Last time I did, I got twenty-nine loads in me~”

That made Rover do a double-take with a small jolt of his head. Meanwhile, the drake giggled a little at the Diamond Dog’s surprised reaction, and responded with his scaled tail lifting a little higher. “Although, I have a feeling you guys could give me a lot more in that same amount of time~”

When the dragon lifted his tail completely, standing in a presented state on the mattress, Rover shuddered when he saw a small trickle of cum dribble out from Spike’s hole to slowly trail down the inside of his leg. With a bit lip, Rover had to look away with a blush while feeling his member twitch at that welcome sight. But alas, the canine kept his cool long enough to reply insistently, “W-Well, ummm… lemme get some sheets first…”

Despite feeling eager to take more doggy cock, Spike huffed with a smirk when he saw how riled up Rover was already getting. “You better get something durable,” he replied with an anxious smirk, “Because I’ve been known to rip beddings pretty easily~”

Once again, Spike was completely in his element as soon as the sheets were laid out, and he was fully presented to the doorway while leashed up. He kept his eyes closed as he heard the first Diamond Dog step in with a hungry grow, clearly eager to christen the drake’s first half-shift as their Breeding Bitch. Even though he knew that these canines were undoubtedly riled-up and eager for some release, Spike was pleasantly surprised at how quickly they responded to his offer. Instead of asking any obvious questions or reassurances, the dog just mounted him while his scaled tail was lifted.

The very instant his “shift” began, Spike was almost immediately shoved down onto the mattress as a large Doberman-like brute pinned him down. But despite how jarringly different his treatment from the Diamond Dog felt compared to ponies, the dragon couldn’t have cared less when that thick, meaty cock was shoved into his already lubed-up hole. And as soon as he opened his mouth to yell out in a mix of pain and unbridled pleasure, the drake’s slutty maw was filled with the thick and overbearing taste of unclean canine musk. Spike didn’t even realize a second dog came into the room until another doggy cock was shoved in his mouth, and rammed in hard enough to poke the back of his throat.

Due to the room not having a clock (aside from the tiny one on the punch-in card machine by the door, which he wasn’t able to see), Spike wasn’t able to know how long he’d have before the four hours were up. Of course, even if he did have a clock, the dragon was doubtful he would’ve paid much attention to it with the upcoming parade of canine cocks coming towards his waiting orifices. The instant those first two thick, musky cocks filled his waiting holes, Spike’s mind was clouded in that familiar lustful bliss as he let the Diamond Dogs use him like a living fleshlight.

Surprisingly enough, the first Diamond Dog took his time as he pounded the drake’s slutty hole, despite the finite time and literal line of dogs waiting outside the door. Even though the canine’s claws were jagged and nearly razor-sharp, Spike’s tough scales made it so that he only felt the pressure as he was gripped tightly by the Doberman. He wanted to moan out lewdly as he felt that meaty knot prod against his hole, but the only sounds he could emit were muffled sputters because of the other cock sliding in and out of his throat. It was clear the dog in front of him hadn’t bathed in a while, but that musky and primal scent just made the dragon’s cock harden at breathing in something so animalistic and masculine. Due to the strain in his throat causing tears to build up a the corners of his eyes, combined with the forceful way the Diamond Dog gripped his green scales while thrusting into his mouth, Spike barely flinched when the Doberman groaned loudly and popped his thick knot inside of the dragon’s well-used entrance.

“Mnnnnnph~” The dog growled loudly inside of the room, which made Spike’s nerves tingle when the sounds echoed and reverberated in his ears. While his eyes rolled back while slurping what he could of that cock ramming in and out of his mouth, he overheard the canine knotting him from behind say, “You’re a tight little slut, aren’t ya?~ It’ll be a shame to see it turned to a stretched-out cum-dump by the time this is over~”

Despite that teasing statement, Spike just shuddered blissfully around the two cocks inside of him. If he was able to speak through the doggy meat throbbing in his mouth, he would’ve dared the Doberman to try his best. Given how many cocks he’d taken in the past month alone, the dragon was cocky that nothing could leave him too gaped or overused. Of course, a small part of his mind pondered the idea of a Diamond Dog being able to do it when ponies couldn’t. Especially given how thick those knots felt when shoved into him...

Alas, even though Spike couldn’t audibly jeer the canine into going rougher to prove him right, he had a feeling the dog got the message as soon as that first hard thrust drove in hard enough to make him to wide-eyed. He let out a garbled grunt through the cock buried in his mouth, but was barely heard over the grunting from either of the Diamond Dogs penetrating him. By the time the Doberman was beginning to pull back to deliver another hard thrust, making sure to tug hard against the inside of Spike’s hole with his knot, the other Diamond Dog was already panting and reaching his peak with his movements becoming more erratic.

Spike couldn’t get a good look at the dog he was blowing, partially from the angle he was underneath him, but mostly due to the thick shaggy fur that laid in greyed clumps along his chest and stomach. But instead of pondering what breed or age this canine may have been, the drake just kept his eyes closed as he savored that salty and bitter musk stinging his tongue with each slide of the shaft between his wet lips. The drake could feel how hard the doggy cock was pulsating, and knew exactly what was going to happen next.

Spike clenched his eyes shut as he kept his mouth open wide, anticipating having that meaty knot getting shoved into his maw and for his stomach to be delivered another massive volley of canine cum. But instead, the claw gripping Spike’s head pulled his mouth away at the last second. The drake instinctively gasped a huge breath of air, but was only empty for a second before a huge spurt of doggy cum shot straight into his open maw. Spike almost choked on the sudden volley of jizz that was sucked down his throat, but he was held in place as thick strands continued to surge out of the dog’s knotted cock.

Even though the dragon was slightly disappointed to not get his mouth knotted like his rear was, it was hard for him to complain when his mouth was flooded with that familiar flavor he loved. His face was slathered in several thick ropes of cum that splattered across his face, and hung obscenely from his green scales. It was only the first dog to use the drake’s mouth at the start of his shift, but Spike already looked like he was bukkaked by a whole group of stallions by the time the canine finished with his last heated groans. Spike opened one of his eyes after that first orgasm, and instinctively kept his mouth open before a final glob spat out onto his glazed reptilian tongue. As soon as the first cock pulled away from his face, Spike shuddered and reclosed his eyes before swallowing his mouthful eagerly.

Due to the intensity of that first cumshot, Spike almost forgot about the Diamond Dog plowing him from behind until feeling a particularly hard yank from that meaty knot. That brief surge of pain was enough to throw the slut out of his temporary stupor to moan out hoarsely, not realizing a couple thick strands of fresh cum were connecting his lips while his mouth was wide open. As the other Diamond Dog got himself off the bed, making sure to use a paw to slather that jizz all over Spike’s face like a marking, the Doberman waited until he was off the bed to shove the dragon’s head down on the mattress and pound his slutty hole even harder. Spike may have been less than half the size of the canine, but he was still mewing out loudly in utter bliss as he felt that knotted cock rut him so thoroughly. Due to his face being shoved into the bedding, smearing the first dog’s cum all over the fresh sheets, Spike’s randy moans were temporarily muffled, which meant the most dominant sound in the room was of the Doberman’s plump balls slapping so lewdly against the dragon’s with each heated thrust.

Spike had no idea if this guy was just too horny to settle down, or if all the Diamond Dogs were going to be equally this rough. Either way, the drake’s body shivered underneath the canine’s as he took every thrust with a grunted moan, his breath tasting strongly of that first load smeared all over his blushed face. His mind was so overwhelmed with the intensity of his treatment, that he didn’t register a new Diamond Dog coming up to use his mouth until his head was pulled back up by a dirty claw. By the time the next cock was shoved roughly into his hungry mouth, Spike began to suck on the thick doggy meat just as the Doberman pulsated deep inside of him.

“MMMNNNGGG!!!~” The dog pounding Spike from behind got a hard grip on both of his plump cheeks, squeezing them tightly just as he felt himself come to climax. Spike clenched his eyes shut as he felt those claws bear down hard on his scales, and that massive cock pulsate inside of his deepest depths. With one last thrust, the dog sunk in deep enough to make the pointed tip of his cock poke against the inside of the drake’s torso, which made the scaled slut squirm hard around the other ramming itself down his throat. But as soon as he felt that thick volley of warmth flooding the inside of his already swollen backside, his shudder was strong enough to be felt by both dogs while being filled with so much pent-up, overwhelmingly hot seed.

“Ahhh… AHHH!!~” The Doberman cried out as his climax lingered on for almost a full minute, with each throb of his cock flooding the inside of the dragon even more with his voluptuous cum. Spike shivered as he felt his body expanding a little from that first load alone, and could only imagine how stuffed he was going to be by the time this shift was over. Meanwhile, the Diamond Dog writhed wildly on top of the whore as he gave him his fill, keeping his eyes closed to ignore the other canine thrusting into Spike’s drooling mouth. Meanwhile, the drake just laid between the two in a dream-like state with his eyes half-lidded, savoring the feeling of such a heavenly load filling him while letting his throat be stuffed repeatedly with cock.

By the time the Doberman finally popped his knot out, a heavy volley of his seed flooded out of the drake’s loosened hole to seep down his legs and leave a puddle on the bed. Of course, the only response Spike could give to that was a sputtered groan between eager thrusts from the canine still rutting his face. As the dragon’s heart continued to race from exhilaration and lust, and his cock throbbed hard as it dangled steadily between his pudgy legs, he felt like he was in absolute heaven when he felt a new Diamond Dog getting into the bed. Not even a minute after the Doberman finished inside of him, another canine was sliding in to take his place like clockwork.

Spike had no idea how quickly the four hour shift might feel by the time this was over, but he was more than eager to find out while he closed his eyes and savored that immense fullness he felt from both ends. He may have not been meant for “breeding,” but he still wanted these dogs to all plow him like he could. He wanted to feel each of their heavy leads flood every inch of his body with their rich and virile seed. He wanted to feel just how rough and primal these underground beats really were, just to have something to brag to Rainbow Dash about the next time they were out. He wanted to be absolutely bloated with cum by the time this was over, to the point where he could barely walk out of these caves without rolling around like a ball. But most of all, Spike wanted to drain every single Diamond Dog’s balls in the four hours he agreed to spend in this room, just to make sure none of them were left unsatisfied.

Despite being stuffed from both ends, as well as jolting between them from the feel of that second knot popping inside of his cum-dump of a hole, the drake decided to make his shift count by lifting up both of his claws. Since he was comfortably pinned between both Diamond Dogs, Spike had no issue with bringing out his digits and making “jerking off” motions with both of his arms. Fortunately, the silent offers were quickly accepted while Spike had his eyes closed, and two more Diamond Dogs rushed in to shove their cocks into his claws. And like that, the scaled slut sunk into his depraved and sex-focused mindset while jerking both cocks off at the same time, his mind slowly clouding up as he sank into the abyss…

“Jeeze... “ Rover, who was fairly spent after experiencing his second orgasm that day with the aid of Spike, could only stand against the wall by the time-card machine and shake his head in disbelief. Only five minutes were left in Spike’s “shift”, but the drake didn’t seem to show much fatigue at all while sandwiched between two of the last dogs. Although, it’d probably be hard to tell how tired the dragon looked when most of his face was coated in various ropes of Diamond Dog cum. The drake’s back and tail were generously drizzled with splooge as well, and slowly dripping from his sides to collect in the large puddle underneath him. Of course, given how over-stuffed Spike looked right now, it seemed like a miracle that he didn’t explode like a water balloon.

If Spike’s head wasn’t so clouded with sex while being fucked from both ends, he probably would’ve realized how hard it was going to be for him to leave these mines without some assistance, let alone try to convince Rarity that nothing happened outside of business deals. After taking countless loads inside of him from the back, as well as swallowing as many as he could that shot in his mouth, his torso was completely swollen with Diamond Dog cum. Even if he were to wash off all the cum that was splattered over his scales (especially his claws, which were absolutely coated due to all the clawjobs he gave), there was no way he’d be able to hide his vastly protruded belly and sides from someone as detail oriented as that fashionista.

But as he took the last of the pent-up and filthy canines, the only thoughts running through Spike’s head were about how gratified he felt in that moment. With every elated groan he heard from the Diamond Dogs above him, and the flooding warmth that filled every inch of him from the inside when they came, the drake couldn’t help shuddering in utter glee. It was clear that these guys needed some physical relief for a while, and the fact that he was able to help satisfy them (while also assisting in their financial negotiations to satisfy them living-wise) gave an amazing feeling of pride to the dragon. All he did was let these canines use him as a cum-dump for the afternoon, but he knew that none of them were going to forget this sort of generous act; heck, maybe this could help unite the Diamond Dogs with ponies and begin a newfound friendship between them.

Or at least, he could use that to calm Twilight down if she were to find out what he did with them.

“Ahhhh!~ S… S-Spike, I’m…”

That strained voice made Spike pull himself from his thoughts while blowing the last of the Diamond Dogs, and glance up at the Mastiff who was biting his bottom lip hard. The dragon narrowed his eyes on him sultrily, despite being pounded repeatedly by the Rottweiler behind him. With his lips wrapped around that massive cockhead, Spike perked his brows up teasingly, silently coaxing the canine to flood his drooling maw with another thick volley of cum. Even though he already took enough loads to lose count, the drake groaned around that cock in yearning desire for that taste one last time.

But strangely enough, the Diamond Dog didn’t seem to feel that same way. After a heated groan and his face clenching up in control, the Mastiff pulled his member out of Spike’s mouth completely. The dragon gasped several times in surprise, but quickly turned to a long and lingering moan as he felt the Rottweiler teasing his loosened hole with a hard tug of his knot. Spike writhed and bit his tongue in immense pleasure, desperate to keep himself from cumming the sixth time that afternoon. While feeling that doggy cock slide back in to tease at his prostate, his emerald eyes peered back up at the pent-up canine in front of him with a tempting smirk. “W… What’s the matter, pup?~ You… You don’t want me to s-swallow?~”

That statement and expression of the drake’s was enough to make the Diamond Dog turn his head away and clench his hind legs tightly. After a shuddered grunt, the Mastiff breathed out strongly and replied, “I… I wanted to finish in, ummm…”

He motioned his head to the dog currently plowing Spike’s plump and cum-splattered rear, indicating what he wanted to do. Even though the Rottweiler had his eyes closed in focus, he still huffed and replied between hard thrusts, “Y-You need to wait your turn! I’m still fuckin’ this whore back here!”

Spike cried out with his eyes clenched shut as that cock rammed into him even harder, sinking deep enough to cause spurts of cum to shoot out from the inside due to volume displacement. But despite feeling those splatters of his friends’ loads clinging to his fur, the Rottweiler kept going with a hearty growl while hearing the dragon below him mew out in response. Meanwhile, the Mastiff just groaned in growing need while watching Spike getting plowed so mercilessly, wanting nothing more than to take his friend’s spot.

“You… You could…” With his thoughts so hazy from the near constant stimulation to his prostate, Spike could barely hear what was coming out of his cum-drooling mouth between heavy pants. While the Rottweiler kept ramming him hard, the drake’s voice came out in wheezed breaths as he said impulsively, “... you c-could al… always… sh-share~”

Rover had to shake his head clear, almost feeling like he imagined hearing that. But alas, it didn’t seem like the cum-coated dragon was exaggerating while looking up at the surprised-looking Mastiff. The Rottweiler kept going, but his thrusts weakened a bit as he looked down at Spike worriedly. “Ummm… what?”

“Yeah, what?” added Rover as he stood nearby with a cautious stare, and a slight twitch from his sheath. “What do you mean by… share?”

Spike just huffed with a smirk between the thrusts he was taking, turning his head back to Rover like the answer was obvious. “Wha… Whaddya think?” he asked coyly, like he was assuming the Diamond Dogs didn’t know what that word meant. After an especially shaky moan when the Rottweiler paused his movements and pulled back to tease his hole again, Spike shuddered before turning back to the mastiff in front of him. “I m-mean… Y-You two could see if you can fit~”

After all the primal fucking he experienced from these canines, Spike’s mind was running on autopilot by the time he clarified his request. Not even thinking about what might happen, the idea of being stretched past his limits was the only thing running through the drake’s cum-hungry mind. With the only other thought being whether he could be as gaped-out as that Doberman claimed he could be, Spike turned back to the wide-eyed Rottweiler and asked teasingly, “Wh… What do you say, doggie? You… you think you could let him in?~”

Realizing what it was the slut was asking to do, the Rottweiler threw his claws up in immediate dismissal. “Whoooooaaaa, no, no, no, no! No way, kid! I’m not gonna have my cock touch his! That’s gay!”

Spike immediately grew a flat, deadpanned stare up at the canine. After a couple seconds of silence, the Rottweiler turned to see that Rover had the exact same expression on him. As did the Mastiff who still had an erection. The dog’s muzzle wrinkled for a second before he huffed and added in his defense, “Y-You know what I mean!”

“Ummm… Spike?” asked Rover cautiously while staring between the dragon and the two dogs between him. “Are… you sure you wanna try that? I mean, I know you’re a slut, but…”

After taking a deep breath, Spike exhaled with a randy smile back at him. “What’s the matter? Afraid I can’t take it?~”

Rover paused when he saw Spike’s insistence, which caused a blush to appear across his cheeks. Meanwhile, the drake looked back up at the Rottweiler and jeered, “I’m not afraid of a little extra cock. Why should you be?~”

Maybe it was the Diamond Dog’s pride, or maybe because he was too close to climaxing to really try arguing with the slut he was penetrating. But as he looked down at that teasing grin, the Rottweiler huffed and took that dare personally. “Oh, you think I’m scared?” he asked Spike condescendingly, not realizing he was giving the dragon exactly what he was coaxing for. “I… I’ll show you scared!”

With a hard grunt, the canine began to pull his knot even harder against Spike’s hole, causing the drake to cry out in legitimate pain from that kind of stretching. Although, considering what the slut wanted, it was clear he wasn’t going to complain now and prove he didn’t want it. So despite the tears building up at the corners of his eyes, Spike gritted his teeth and winced as he felt that massive knot pull even more at his ring, causing it to stretch out and strain beyond its limits for what felt like an eternity. But in reality, the yanking only lasted for a good ten seconds before the Rottweiler popped his knot out lewdly, which caused a steady trickle of Diamond Dog cum to leak out of the drake’s loosened hole.

“T-There!” After a bitter huff, the Rottweiler crossed his forelegs and looked away from the others while keeping the rest of his shaft inside of Spike. “I… I’m not scared…”

Rover scoffed with a roll of his eyes, not expecting one of his toughest miners to act so tsundere because of a little jeering from a baby dragon slut. Meanwhile, a powerful shudder swept across Spike’s body as he felt his hole drooling with so much warm, oozing canine cum, which caused the dog to tremble a little as well from the sensation. But alas, the drake still kept a determined grin as he peered back up at the Mastiff in front of him. The Rottweiler didn’t look back at him, but he also kept himself silent as Spike said invitingly, “Come on, you big pup... I wanna feel both of you~”

Rover’s balls may have been aching from his previous orgasms, but he was still getting hard as he saw the Mastiff getting into position. The Rottweiler was clearly apprehensive, but he still allowed himself to pick up Spike so that the other dog could lay down underneath them on the mattress. Despite wincing uncomfortably from the puddle of cum he was laying on top of, the Mastiff was soon in proper position perpendicular to the Rottweiler, and with Spike nestled between them. The drake grinned hungrily at the sight of that second doggy cock pointed to his currently filled hole, and shuddered at the thought of it giving him a proper stretching.

“O-Okay… Here it goes~” Slowly, Spike lowered himself down until he felt the tip of that member prodding against his hole, while the meaty shaft rubbed uncomfortably close to the Rottweiler’s. The canine already in him cringed at that feeling, but kept his eyes closed as he allowed Spike to keep pushing. The drake groaned in a mix of pain and eagerness as the pointed tip started to slip in, despite how unbelievably tight it felt for both himself and the two dogs involved. But while the head began to pop in, the pressure continued to build up immensely alongside Spike’s deep moans, none of them seemed to notice Rover leaned against the wall and watching them with a paw stroking his cock.

“Ahhhh… Ah, Ah, AH, AH! AH!! AAHHHH!!!~” With that last intense cry that emitted from the back of his throat, the burning pain in Spike’s hole reached its ultimate point as the Mastiff’s shaft shoved in alongside the Rottweiler’s. At Rover’s angle, the sight of two massive cocks stretching out that slutty dragon hole was hot enough to make him moan out while stroking faster. Of course, Spike was more focused on the two canines he was sandwiched between as he shuddered wildly between their hairy and musky chests. “Ahhhhhhh… Hol… Holy shit~”

Spike bit his lip a little, happy that none of his friends were around to heat him say that. For some reason, a lot of his pony friends were more upset by any swears that came out of mouth than they were of any cocks that went into it. But for now, that moment passed in an instant before savoring that overstuffed feeling within and around his burning tailhole. After a shaky exhale through his nostrils, Spike unbit his bottom lip and said in a faint wheeze, “O-Okay… I… I’m ready~”

“Ooh, I bet you are~” growled Rover as he watched while jerking off, his hips thrusting a little at the obscene sight before him. Neither of the other canines took much notice to their boss watching them so lustfully, and just grunted in unison as they pushed in together. Spike’s mouth hung open as he moaned out primally, feeling his hole stretch open even more from those shafts sinking in deeper at the same time. He may have not been knotted by either of them, but that intense fullness was more than enough to make his cock throb and linger dangerously close to orgasm already.

Alas, the dragon was able to control his own impulses as more of those cocks crammed into his aching tailhole. Even though both of the canines winced a bit in discomfort from the tightness (as well as the obvious awkwardness of having their cocks touching each other’s), the feel of Spike’s hole quivering around their shafts, as well as the sounds of his elated moans, were able to keep the two dogs close to climax. After taking a minute or so to test their movements, it seemed that the Mastiff and Rottweiler were synced enough to pull back at the same time, leaving the slut between them to quiver and exhale weakly from that fullness escaping him.

But just as those two heads reached the drake’s stretched-out ring, the Diamond Dogs tensed up at the same time before ramming their cocks back in. The sudden force of two cocks filling his hole caused Spike to yell out while wide-eyed, his cheeks deeply blushed at the sensation of something so massive being crammed inside of him. But instead of trying to stop them, or even asking to slow down, all that the dragon did was shiver before a wea smile grew across his randy face. “Ohhhhh… Oh, yeah!~”

After that, both of the canines knew that their slut was ready for more. With the sounds of Spike’s enthusiastic moans ringing in their ears, and their shafts being caressed so tightly by the drake’s tailhole, it wasn’t long before the two of them began to moan out faintly as well. The two dogs were holding Spike by his shoulders and torso while he was between them, pushing the slut up and down their cocks like a shared sex-toy that was constantly shuddering in their grasp. Each time the two cocks slid in deeper inside the drake, reaching closer to the base of their knots, Spike’s moans became louder as his tailhole was outstretched more and more. He had no idea if he could actually take those cocks completely before either of them came (or if he came first), but he still breathed out in heavy pants and tried to say, “Gi… give it to me, you... d-dirty dogs!~”

“Yeah!” moaned out Rover with half-lidded eyes as he stared at those massive, meaty cocks stretching out the slut well past his limits. “R… Ruin that little whore!”

That added incentive just made Spike moan out even deeper, and he impulsively began to move up and down those shafts more eagerly than the canines pushing him. He could feel how strongly both of those members were throbbing while his tailhole was wrapped around it, and he was determined to milk those cocks for all they were worth. His heart raced in exhilaration and hunger, not caring about how badly his hole was burning from all the stretching and strain he was giving it. With his own cock leaking a steady dribble of pre all over the Mastiff’s stomach, all that was running through Spike’s mind was the dire need to bring both of those cocks to orgasm at the same time.

“C… Come on!” moaned out Spike between hearty breaths as he rode those doggy cocks faster than before. He could hear how badly both of them were groaning between deep pants, knowing they were gonna cum soon. Despite the sickly scent of dog breath wafting in among the lingering cum and musk smells in the room, Spike was still breathing in deeply as he felt himself get closer to his final dirty release. And as soon as he heard the Mastiff let out a breathed cry from underneath him, Spike closed his eyes as he clenched his tailhole as best as he could, giving both of those canine shafts a good squeeze to coax them to unload. “Y-You heard Rover! R… RUIN ME!!”

The instant Spike said that in overwhelming desire, the drake’s entire body tensed up as he came for the final time that afternoon. His balls may have been aching nearly as bad as his hole, but his nerves still tingled in immeasurable pleasure when his cock throbbed and spat out several meager ropes of his draconic seed. His orgasmic cry was more than apprent to the dogs in the room, and his climax helped tighten his hole just enough to bring both of the canines to their brink as well.

The Mastiff was the first to cum, moaning out just seconds after Spike began to finish. His claws bore down hard on the drake’s back as his cock erupted deep into his scaled body, letting out a massive volley of cum that caused even more of Spike’s little torso to swell out noticeably. Spike’s body writhed in deep pleasure when he felt that first familiar blast of warmth and pressure inside of him, as well as from the sound of that second-last elated cry in pleasure from the Diamond Dog

Of course, the Rottweiler only needed two more thrusts to come to his own climax, which was slightly easier when the tightness of Spike’s hole (as well as the Mastiff’s cock) were given that last-minute addition of lubrication. The canine gritted his teeth and groaned needily with one last push, actually getting the base of his knot to touch Spike’s hole to deliver his load even deeper than the mastiff. Spike cried out once more as he was given a proper breeding from the last canine, his toes curling at the feel of so much hot seed flooding in to bloat out his belly with that cum he wanted so badly.

Rover got a perfect view of both of the dogs cumming into Spike, as well as their seed dribbling out between their cocks to leak onto the bed. That image, combined with Spike’s enthusiastic moans, caused the head Diamond Dog to cry out heartily and finish while leaned against the wall. His paw spastically went up and down his dirty shaft as thick ropes of his seed splattered out on the carpet, helping to add to the already overwhelmingly musky smell that was lingering in the room. The canine tensed up so much during his orgasm, that he almost fell to the floor by the time he was finished due to his wobbly legs.

Alas, by the time Rover was able to collect his breath, and wipe his cum-drenched paw on the already ruined sheets, Spike was in a near-comatose state between the two last exhausted Diamond Dogs. Rover knew that the drake would need to head back to Ponyville soon, but neither he or the others could move very much after such an intense finale. After a heavy exhale, the grey canine shuddered with a bit lip as he headed towards the bathroom and said, “I’ll… g-get the shower ready…”

“Ugh, come on! It can’t take that long to wash up!”

Standing outside one of the Diamond Dog burrows, Rainbow Dash was tapping her hoof impatiently as she waited for her fuck-buddy to come out. She wanted to go down to the caves herself to check up on Spike, since he hadn’t come back in hours. However, the little dog named Spot was nice enough to come out and tell her he was just about finished. But still, it was hard for the pegasus to not bite her lip in a mix of worry and slight offense.

Honestly, Rainbow wasn’t sure what she should be more upset about: that her good friend with benefits probably violated a Pinkie Promise to get an unholy amount of Diamond Dog dick, or that he went down to the caves himself and didn’t bring her along! If he really did get that much action, she was gonna give him a piece of her mind for doing something so greedy. Granted, Diamond Dog cock probably couldn’t beat Wonderbolt cock, but still!

Fortunately, the mare’s brooding thoughts lasted for only another moment more before hearing some rumbling from underground. The first head to pop out from the burrow was Spot, who seemed rather spry as he came out from the hole and stuffed a paw back inside. And with a hard grunt, the small Diamond Dog helped pull out Spike with a surprising amount of strength. Of course, as soon as the dragon rolled out from the burrow, Rainbow Dash’s jaw dropped when she saw how bloated he was.

Spike may have been cleaned up, but Rainbow could still tell the dragon’s body didn’t get that swollen from eating a lot of gems. He fell forward on his stomach when he got back into sunlight, with his pudgy legs unable to even touch the ground due to his heavily protruded gut. Even if a naive pony were to think Spike got that bloated from something other than swallowing gallons upon gallons of spunk, any lie he could’ve gave would’ve been instantly caught if they smelled his breath. Rainbow was a couple feet away from Spike, but she still bit her lip with a blush when she caught the strong scent of cum coming from him. Meanwhile, the drake just sighed dreamily when he saw it was Dash who came to check up on him.

“Uhhhh… H-Hey Dash~” said Spike rather tiredly. Spot, upon realizing there might be an awkward moment from Rainbow’s peeved expression, silently made his leave back underground. As soon as the dog covered the entrance with a good mound of dirt, Spike raised a claw before his friend could say anything. “Trust me, I am definitely gonna let you come along next time~”

“Ugh.” Rainbow just rolled her eyes and turned her head away. Even though she was kinda happy he said that, she was still upset enough to say back at the dragon, “So, what exactly are you gonna tell Rarity? Because I bet even someone like her can smell what you were doing.”

“D… Don’t worry…” Even with his bloated figure, Spike was still able to roll back into a seated position reach into his backpack. Despite shuddering a bit with a wince at sitting on his rear again, the drake ignored it and pulled out the folder Rover gave him earlier. “I got all the business stuff taken care of before anything good happened. Believe me, I kept her business stuff away from my pleasure stuff.”

Rainbow just stared at him with narrowed eyes while a brow rose suspiciously. “You sure about that? Because you did make a Pinkie Promise to not sleep with them.”

“Technically, I Pinkie Promised not to solicit any sex from them,” corrected Spike with a raised claw in clarification. “Which, I did not do. They solicited me.”

Rainbow Dash may have understood her friend’s loophole (and even admit to herself it was an impressive one), but she still skewed her muzzle worriedly. “I dunno, Spike. I mean, I get why you did it, but I really doubt Rarity would appreciate you skirting around her rule like that.”

After straining himself a bit while getting back on his feet, Spike wobbled for a moment before sighing. “Well… I really did make sure the business stuff was taken care of first. Just because I slutted myself to the Diamond Dogs afterward doesn’t mean it’ll get in the way of her business dealings with them. They solicited me, and I wanted to be polite! If anything, it’ll just make any future dealings even better since they…”

As he talked, Spike saw Rainbow Dash’s eyes widen while looking just above him. She didn't say anything, but her fretful expression caused Spike’s words to slowly trail off. He paused briefly to ask what was wrong, but the looming shadow he saw in front of him caused any words to stay muted as well. After several seconds of silence, the drake was starting to look worried as well.

“Uhhhh… she’s right behind me, isn’t she?”

Rainbow Dash didn’t nod, but her cautious steps backwards were enough of an answer Spike was afraid to find out. The dragon slowly turned his head around, his heart racing in sheer terror the instant he saw the white unicorn standing behind him. Rarity may have been one of his sweetest friends, but her glare was dangerous enough to make Spike’s balls crawl up into his throat. But despite his overwhelming feeling of absolute dread, the drake tried to make the corners of his mouth crack into a shaky smile. “Uhhhh… heh heh heh… Ummm… H-How much did you hear?”

SMACK!!!
