Chapter Seventeen: Defiling A Diamond (Part 2)

“Oh. My... GOSH!!!~” Rainbow Dash’s face lit up brighter than a Hearth’s Warming tree. “Ohmigosh, like… wow! I mean… holy crap! I didn’t expect you to wanna join after seeing me take just one!”

While the white unicorn cringed and looked away from her excited friend, Spike was quick to place a claw over Rainbow’s mouth to shut her up. “Come on, give her some space,” ordered the drake as he pushed Dash away from Rarity’s side. The pegasus pouted with a huff, but complied when she noticed how hesitant their friend was looking. Spike then looked back at Rarity and asked, “So… do you want a hole for yourself? Or... would you rather share one with one of us?”

“OOH! I’ll share a cock with her!” piped Dash with a tone that seemed more expected of a perverted Pinkie Pie. “I mean, it’d make sense, right? One mare helping out another…”

She then shot a sultry glance back at Rarity with a knowing wink, indicating how genuine her interest was. Rarity’s blush grew even deeper across her ivory cheeks, but her muzzle didn’t open to state any refusal. Instead, the unicorn breathed out faintly through her nostrils while biting her lip in trepidation. “W-Well… I suppose I’d be a… little more comfortable with another mare. Umm, no offense, Spike.”

“None taken,” replied the dragon with an understanding wave of his claw. “Don’t worry, I get it. Have at her, Rainbow!”

“You got it~” purred the pegasus sultrily as she grabbed her friend and led her back to her spot. Meanwhile, the drake was quick to try something a little different this time. He went into the restroom to grab a footstool, and brought it out to place underneath his own glory-hole. Spike then went back to the shelf, and grabbed one of the many bottles of lube for obvious reasons. He poured a generous amount of the water-based material on his claw before getting back on his stool, and moaned the instant he brought it back underneath his tail. The dragon grinned wide while getting himself prepped, sliding a couple of his slicked-up digits into his waiting tailhole as he leaned by that waiting opening. He gave a couple more knocks to the wall after he finished and got in position, just in case any more Diamond Dogs were outside.

He didn’t have to wait long as he heard the steps of a some random canine approaching his hole, clearly having noticed the lubed up pucker that was pressed tightly against the wall.

“Ooooh… seems like a dragon breeder got addicted to our cocks,” the dog joked while poking his tip teasingly around the drake’s excited and quivering ass, “If you plan on being our permanent bitch, you better be prepared. I really wanna stretch your little ass out, and make you the loosest bitch in our clan~”

Spike shuddered with an antsy grin at that claim, and almost wanted him to try and do it. Of course, even if the dog could hear him through the sound bubble, the drake already knew that if two Diamond Dog cocks couldn’t ruin his ass the other day, then this one probably wouldn’t either. Nevertheless, the scaled slut still groaned in wait while holding onto his stool with one claw, and biting down hard on the other. Meanwhile, the canine cock began to prod into Spike’s cum-dump of a pucker, determined to give the slut his fill of yet another virile load. “Nnnnnnn…~”

“Hmmm?” The voice paused for a second as if he noticed something, and then shouted a couple seconds later, “Hey, guys! There’s a second hole open! Get in on this!”

“Heck yeah! I heard there was a pony slut here! I always wanted to fuck one of those!” another Diamond Dog answered enthusiastically as he quickly strode towards the available hole. Rarity, who was sitting by the hole with a smirking Rainbow Dash beside her, gulped nervously at hearing such a brash and familiar voice. She was sure it was one of the many brutes who took part in keeping her prisoner in these caves a while back, but she couldn’t exactly tell who it was after so long. Despite what she may have said a minute or so ago, the unicorn’s heart began to crawl up her throat in looming fear that she would regret this hasty decision.

However, before the mare could even think to say anything in refusal, she gasped when the massively thick and veiny cock poked through the hole between the mares’ faces. “There you go, you fuckin’ whore,” jeered the canine teasingly from the other side. “Hope you’re hungry~”

“I certainly am!” chirped Rainbow enthusiastically as she instantly dove in. While Rarity’s jaw dropped, she watched as her friend slurped one side of the cock without hesitation. The pegasus slut ran her tongue run over the thick, hot, and salty dog meat while moaning a little under her breath. She shivered in satisfaction, clearly trying to entice Rarity as she gave some long slow and teasing licks, even going as far as up to the tip where she suckled on the succulent and ample amounts of pre spilling just by her oral ministrations alone. She made sure to let the pre even smear around her lips and spill down her chin, giving her an alluringly messy look. Something the Diamond Dogs would no doubt go wild for if they could see her right now.

“Mmmmmm…~” The cyan mare locked her bedroom eyes back at Rarity, whose face was now as red as Big Macintosh’s due to being in such a close proximity to her whorish friend. Of course, the near-overwhelming scent of the Diamond Dog’s heady musk may have played a small factor to the unicorn's hue as well. As Dash slowly licked her lips of that deliciously potent canine pre, she used a hoof to gently grasp the base of that cock and make the guy shudder strongly through the hole. She began to stroke that rigid member teasingly, but also pointed it closer towards Rarity’s face while cooing in a sweetly seductive tone, “C-C’mon, Rare… Just... close your eyes… and give it a little lick~”

Rarity felt conflicted, but she couldn’t help but inch closer without even realizing it at first. Her body seemed to have a mind of its own, with her legs bucking against the floor in arousal as she neared closer to that cock. It's… It’s just a taste, she thought to herself as more of that intoxicating musk flooded her lungs and clouded her senses. There wouldn’t be any harm in it, right? It’s just to see why Rainbow is voraciously eating it all up...

As she neared, Rainbow jerked a little harder to make the cock spurt some of its pre, hitting Rarity square on her muzzle. Dash gasped a little while trying not to laugh in response, especially when she saw how Rarity froze to the feeling. It was hot and slimy, and something she would normally wrinkle her nose about in disgust. But now...the heady scent only seemed to lure her in more, like a rafflesia flower coaxing in its prey. Only that she was the one feasting, and the benefits might be beneficial for both parties involved.

Not to mention that it was only polite and generous of her to help them out, wasn’t it? Selfless is what Rainbow called it, and selflessness is just another word for generosity...

Rarity didn’t need to think of any more subconscious coaxings to make her comply, as her eyes slowly closed on their own while breathing in more of that rich aroma. Rainbow grinned even wider as she watched her friend shakily open her mouth, like her body was taking complete control over her lust-addled mind. Even though she didn’t want to jinx her friend’s big moment, she couldn’t keep silent the moment she saw the unicorn’s tongue start to pull out of her maw towards the canine’s twitching shaft. “Mmmmmm… That’s right, Rare,” she whispered in lustful encouragement as her own muzzle went back in. “Taste it. Lick it~ Embrace how awesome this all feels…”

Even though she could hear her friend’s words ringing through her head like something from a vivid dream, most of Rarity’s mind was lost to the sensations she felt the instant her tongue graced that smooth and hot flesh. The taste really was as strong as the drake had described, with the muskiness hitting her tastebuds like a filthy saltlick. However, despite how hard her heart pounded from the taboo nature of that first contact, and how faint her breathing became in shock of her own actions, the only thing that could come out of Rarity’s open mouth was a sheepish, but still audible moan. As her cheeks burned hotter in shameful exuberance, the unicorn slowly dragged her tongue along her side of the canine’s shaft, which made the pure masculine taste intensify inside her mouth and make that moan come out fuller.

As soon as her tongue flicked the tip of the Diamond Dog’s cock, Rarity felt a generous glob of wet pre smear against her tastebuds. The flavor was just as bold and potent as the musk wafting through her nostrils, and it made her fur stand on end from the sheer exhilaration of such a wild taste. Halfway through the unicorn’s first taste of doggy cock, the canine gasped and moaned loudly when he felt Rainbow’s tongue slide up the other side of his shaft as well. By the time the unicorn was finished, her pegasus friend already had her muzzle waiting at the tip for Rarity to meet her.

“Ho… Holy shit, are there TWO sluts?!” uttered the canine in a gasped breath while shivering against the wall, his cock jerking at the arousing realization of two tongues fellating his red throbbing shaft instead of just one. Even though the response caused Rarity to reopen her eyes in worry, she was thankfully calmed-down the instant she saw Rainbow’s reassuring smile back at her. After licking her lips once more to savor that primal taste the canine was giving off, Dash bent in and began to suckle lightly on that throbbing cockhead. Meanwhile, her eyes peered up at Rarity with the most sultry bedroom stare, silently coaxing her to join in.

The unicorn paused for a moment with her heart thundering in her chest, but her mind was completely blank and unable to give any resistance. Instead of worrying about how she may have looked, or how things might change after this, all that Rarity saw was her exuberant friend, and that tempting member being teased by her lips. And without even realizing it, Rarity licked her own lips with a light groan before completely giving in, and closing her eyes to give her friend a little kiss.

With that, the Diamond Dog moaned out heavily as he felt both pairs of lips sucking on his head, while the two mares kissed each other with that canine cock nestled between them. It was then that Spike let out a loud and husky moan, as his own doggy cock finally decided to take a dive deep into his slutty rear. The Diamond Dog behind him growled in approval, “You convinced TWO of your slutty pony friends to whore themselves out to us? Guess such a nice draconic whore like you deserves a reward~”

To emphasize his point, the Diamond Dog pulled his cock out to drag Spike’s plot even tighter against the wall, before shoving it back in to stretch his scaly and flexible ass. Spike had to brace himself as best as he could, or risk being pushed off the stool by the eagerly bucking canine. The dog certainly had no trouble finding purchase in that overused ass as he claimed more and more of it, pushing deeper and giving the slutty drake just the filling he needed. With each hearty thrust the canine delivered, Spike squealed out in overwhelming ecstasy while his eyes remained shut; even though he could hear his friends enjoying themselves, he wasn't able to look back at them while writhing in pleasure from his own rutting.

“Who’s a good breeding bitch dragon?” the Diamond Dog jeered, never ceasing his strong thrusts as he worked Spike’s ass open. His knot pushed hard against the drake’s overworked pucker, eliciting a blissful squeal from the breeding slut while shuddering wildly.

“O...OHHHHHHHHHHH! I AM!” Spike cried out in ecstacy, his tongue rolling out in clear enjoyment of his situation. The wet squelches coming from his ass showed just how much his sphincter was eating this canine cock up. The stool he was on almost tipped over a couple times due to the ferocity of the dog’s plowing thrusts, but the little slut remained in place while receiving the ramming he so rightfully deserved. Meanwhile, his ears twitched as he heard the increasingly wet and cooing slurps of both mares who were sharing the other Diamond Dog’s cock.

The Diamond Dog behind the mares groaned deeply, clearly enjoying the feel of those two pairs of lips now caressing both sides of his shaft. While the unicorn had her eyes tightly closed to savor the moment (and also ignore what she was fully doing), Rainbow was still staring at her friend lustfully while imagining what she could do with such a prissy mare. Rarity wasn’t sure which was making her heart beat harder: the increasingly preferable taste of that musky cock in her mouth, or the feel of her friend’s lips against her own while she did it. As the two made out lewdly with that hefty amount of cockmeat between their drooling maws, they soon heard the dog moan out, “Ahhhhh. This is soooo good, b-but... it would be even better if... o-one of you sluts throated me, and... the other used that mouth on my balls~”

Just in that moment, the Diamond Dog pushed his cock fully through the hole, making sure to present his furry orbs as well to be serviced by some eager whores. Rarity pulled her lips back with a wet smack, and made a shivered gasp at such a hefty pair of balls (as well as by the much richer scent of musk that came through the hole with them). The scent was so raunchy and raw, but it also made her hind-legs rub against each other in increasing desperation. Meanwhile, Rainbow leaned her muzzle above that cock and planted her lips fully against the mare’s, catching her by surprise with a deep and passionate kiss that lasted for only a few seconds. When Dash finally pulled back, leaving her friend panting rapidly while wide-eyed, the pegasus slut grinned wide and said, “If you let me take this cock, I’ll give you something really nice to taste after~”

Rarity couldn’t help but whine, not quite sure about the offer considering her dire need, “But you already had one, darling! And… and I’m not sure how long I can hold out right now!”

Rainbow merely huffed before saying, “If you’re gonna cum, just do it the next time it happens. Believe me, it’s gonna happen a lot~ You might as well get the easy one out of the way. Besides...”

As she trotted over towards the tip of the canine’s twitching cock to begin sucking, Dash made sure to turn around to show off her used, cum-dripping marehood to the instantly blushed Rarity. As she shamelessly showed off how loosened and drooling her winking snatch looked, with so much of her cyan fur being matted by that potent canine seed, Rainbow said in a teasing tone towards her friend, “After today, who knows? Maybe you’ll get more than me~”

Rarity was biting her lip, unsure how jealous she should’ve felt about seeing her friend’s marehood so stretched-open and claimed by just one Diamond Dog cock. If Rainbow was going to continue at this rate, there’s no telling how she’ll look by the end of the day. The mental image was intense to say the least, but at the same time… the unicorn’s own loins burned even hotter at the idea of that happening. And not just to her friend either.

Even though she wanted to do something more meaningful for her first orgasm of the day, Rarity eventually sighed and bit her lip in acceptance. Despite how badly her dripping lips were clenching for something to fill them again, the unicorn had a feeling many more will come after her first.

“Fine, but you owe me a favor,” the pristine white mare bargained with a huff, “You really are voracious.”

“I don’t know what that word is, but I’m gonna guess it’s a compliment. So thanks!” After grabbing the Diamond Dog’s meaty shaft with her hoof and shooting her friend a wink, Rainbow quickly sunk her open mouth around the cockhead with a randy groan. The canine moaned out eagerly as he felt the slut’s lips wrap around his cock, which caused his balls to ride up for a moment in front of the unicorn’s blushing face.

“W...Well, that isn’t quite the meal I expected,” stated the mare with a half-hearted smile, still clearly nervous despite her joke, “b-but... a lady should not be picky about her meals...” With that being said, she did what felt fairly natural in that moment. She started by softly nuzzling the balls, and closing her eyes while breathing the strong scent in. The hairs of the ballsack were surprisingly soft in a pleasant way, and the musky scent -- while different from his cock -- had its own unique perverted note she found she could indulge herself in. Her sniffs seemed to tease the Diamond Dog as he groaned. At least Rarity would like to believe that this was for her own gain, and not that of her perversely bobbing friend above her.

The prismatic mare was already spearing her own throat, not hesitating a second as it bulged out from his thick red canine cock. Each motion made the dog’s balls contract, clearly pumping up his pre into the deepthroating mare as an incentive to keep up the good work. It made Rarity realize that she might as well have to step up her game, so she stuck her tongue out, and let the heated appendage slowly and softly run over the orb. The soft fuzz of his balls started to get slathered in her spit, a gesture the Diamond Dog seemed to appreciate with another loud groan. This encouraged the impeccable looking unicorn further in her dirty work, as her tongue glided across the soft furry surface to circle and flick around the balls. She even tried to softly lift them with her tongue, not that it was easy to do considering how heavy and full those musky orbs were. That almost made her feel envious again, but she was able to remind herself that there were many more Diamond Dogs to go around.

Rarity froze for a second as she caught what she was thinking, and realized how depraved she was acting so soon after starting. However, with each drag of her tongue along those fuzzy and deliciously musky orbs, and each gurgled moan she heard from either Rainbow or Spike, the unicorn soon felt comfortable once more with the situation she allowed herself to be in. She may have been a world-class fashionista and Element of Harmony, but right now, all that mattered were those thick and tasty orbs that were resting right on top of her blushing muzzle. And she needed more of them.

With that thought in mind, she practically lunged for those doggy balls as she opened her needy maw wide, and took one of the large orbs in between her lips. She suckled on it softly, while her tongue teasingly glided over the loose skin to make the Diamond Dog squirm. After she had tasted an orb sufficiently, she changed to the other so her muzzle wouldn’t give these succulent balls a break. Her hind legs bucked into the carpeted ground, and her arousal accelerated with each second she played with the canine balls so lewdly.

Meanwhile, Spike could feel just how close his Diamond Dog was getting with each heated thrust into his hungry tailhole. As the slutty drake moaned out helplessly while struggling to stay on his wobbling stool, his own cock throbbed hard when he heard the canine growl out, “You… you better get ready slut! A… After I shove my knot in your little hole, I’m getting everyone to come back and ruin you three!”

“M-Me too!” groaned out the other canine who was enjoying his double-timed oral, “You better open another hole if you plan to finish today!”

Rarity was too busy with the balls in her drooling muzzle to make an audible response, but her strong shudder made it clear she wouldn’t object to her own glory-hole after tending to this cock. Meanwhile, the drake yelled out in a brief bout of pain as he felt that meaty knot ram against his loosened hole, coaxing him to take it and really leave his hole open for business. Due to his experience with the canines the other day, Spike was more than willing to accept that daring knot with his teeth gritted, and he gripped his stool tightly while pushing back as hard as he could.

While his cock throbbed especially hard in response to such a filling, that knot only strained for another moment before it popped right inside that tailhole like it was made for the dragon slut. It certainly would further cement his new position as a Diamond Dog breeding bitch. Not to mention his ass might gape a bit, and be loose just like the Diamond Dog promised. Not that it wouldn’t recover, seeing as he had taken dragon cocks just fine. Still, a loose pucker was an enticing thing to have temporarily, so that every male could truly see that he was the easiest dragon in all of Equestria.

And judging by how enthusiastic his two friends were getting, he had a feeling neither of them would object to a little loosening-up either.

Spike let out a sound between a whine and a moan as the Diamond Dog still pounded him, his knot pulling at his insides and working them over. The red cock was pulsing and just about ready to blow, just like Spike himself. He was on the edge, his cock spewing pre and begging to finally let his own seed splatter around. Fortunately, that feeling was just about to come to fruition when he heard the Diamond Dog behind him say in a raspy moan, “T… Take it, you gaping dragon bitch!!!”

“Nyaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhh!” Spike squealed out loudly, his cock spasming as his cum instantly splattered against the stool and floor. The feeling of having this strong canine hilting inside him being too much. He felt the cock pulsate before hearing a loud groan, which was followed by spurt after spurt of the Diamond Dog’s seed pumping into his claimed rear. Spike’s cock sprayed in time with the Diamond Dog’s, each load eliciting another lewd cry. His cock bobbed in tandem with the dog’s throbs, but it was clear he couldn’t keep up with how productive the Diamond Dog was. The feeling of the knot expanding upon climax was especially amazing, and even though his cock couldn’t spew any more cum, it still tried as it twitched from each stomach bulging volley that was delivered. By the end of it, Spike felt positively bloated with cum, seeing as the large knot made sure to not let a drop escape the breeding slut.

While the little dragon waited for that meaty knot to soften enough to pull out, Rarity was becoming just as invested in her newfound interest as Rainbow was. The pegasus may have been giving it her all with her skilled sucks, and using her training with the Wonderbolts to give that canine shaft a thorough cleaning with her hungry muzzle, but her friend was getting rather dedicated to her own tending as well. With each breath Rarity took of that musky scent, her moans became deeper and more primal as she sucked every inch her lips could touch. She had a feeling this was one of the Diamond Dogs who attacked her over a year ago, but she couldn’t have cared less now as her tongue and lips tended to that fuzzy sack. Between the unicorn’s legs, her lips were glistening in her secretions as she grew tremendously wet and antsy from such a taboo moment with her friend.

After an eternity of being filled with so much doggy cock, it seemed like Spike was done. It was then that the drake was pulled back, and he yelped in immense pain from that knot stretching him out again. His ass pounded against the wall as the cock pulled hard, intent to get his knot out of the willing breeder so the next could use him.

The Diamond Dog finally managed with a loud wet pop, making Spike sigh in sweet relief. Even as an obscene amount of cum spurted out of his ass from the massive pull, it was nice to have a bit of reprieve in any case. His quivering, gaping ass could attest to that as it remained firmly placed against the messy, and now currently available hole.

As the drake shuddered and waited for more, Rarity and Rainbow were working towards their own finish with the other dog. Both were expertly servicing the canine crotch in every erogenous zone they could reach, slobbering his cock and balls with passion and massaging them like a pair of well-versed sluts. The dog above them groaned needily, feeling his balls just about ready to give these pony sluts their reward. If Rarity was informed what she would be doing just a day ago, she probably would’ve had a panic attack; but now, with her face willingly buried in a Diamond Dog’s musky and sweaty ballsack, all that the unicorn felt was pure unbridled lust as she let the strong taste burn and linger on her wettening tongue.

“This is it!” growled the canine through the wall. “Open wide! I’m going to use your stomach as my personal cum dumpster you little pony whore!” The Diamond Dog groaned out primally as he shoved his canine cock deep into the rainbow-maned slut, and his balls contracted against Rarity’s skilled tongue. Even though the unicorn didn’t receive any of that hefty load, she could still feel it churning within those orbs while her tongue was pressed against it. And as soon as the canine finally came, and she overheard Rainbow’s muffled grunts as she began to eagerly swallow each spurt of his load, Rarity whined needily while her hind-legs crossed together and dribbled more of her juices from her winking cunny.

“Nnnnnphhhh…” Rainbow clenched her eyes shut as she put her lung capacity to the test, and shuddered while repeatedly swallowing every mouthful that was delivered into her hungry maw. The feel of so much cum flooding her mouth and pouring down her gullet was unbelievably tantalizing, but it was hard to compare that kind of sensation to getting her womb filled with all that rich and virile spunk. Despite how strong and intensely satisfying that canine’s load tasted, her cum-drooling marehood was trying to clench in for more cock to sate her growing cravings. By the time the Diamond Dog finally finished, and he shivered with a pleased moan before pulling away, Rainbow was gasping for air the instant that member was pulled out of her mouth.

“Ho… Holy shit!” gasped Dash as she took a moment to collect her breath. As the cock disappeared, and the canine chuckled in satisfaction before walking away, the pegasus fell on her flank due to how wiped-out she felt. Her eyes remained closed as she said while regaining her senses, “Y-You know, I… I wouldn’t be surprised if I still taste that in a week.”

Rarity couldn’t help but whine, the thought alone making her cunt gush and wink, “I...I didn’t need to hear that with how unfulfilled I feel right now!”

Rainbow’s ears dropped when she heard her friend’s strained reply, and she frowned before saying, “Hey, ummm… I’m sorry if you didn’t like it. But, uhh… just know that it really means a lot that you at least tried, you know? And… I promise I won’t tell any--”

“No, I don’t mean it like that!” after huffing in exasperation, Rarity went over to the glory-hole door between Dash’s and Spike’s to open it. “I… I can’t take it anymore!”

After opening the door to expose the large hole inside, Rarity turned around and planted her flanks right up against it, much to the surprise of both of her friends. The pent-up unicorn shuddered as she stayed in such a lewd and improper stance, not even caring who might come by as she kept her marehood fully exposed and winking for use.

“Ummm… R-Rarity?” asked Spike in a cautious tone, not wanting his friend and former crush to go too far just because she was horny. “Do… you at least want to use one of those condoms fir--”

“Spike, so help me to Celestia if you try to stop me, I will not hold myself accountable for my actions!” Too pent up to even realize what she was saying (or how shocked her friends both looked from her behavior), Rarity clenched her eyes shut and used a rear hoof to kick the wall a couple times. By the time a couple new canine voices could be heard, the white mare was leaking enough to leave a distinct trail of juices down the wall on the other side of the glory-hole. Her erratically winking pussy was practically begging for cock as Rarity used her hoof to insistently knock on the wall behind her to draw the attention of these canine beasts.

“Awwwww, shit! It seems like they were right!”

“Holy shit, that white pony slut is dripping down the wall!”

Rarity shuddered with a needy whine while hearing the Diamond Dogs refer to her marehood in such a demeaning way. She then heard a low and lingering growl, followed by the faint sound of something sliding up the wall underneath the hole. It didn’t take long for the unicorn to realize that one of those savages actually licked her juices from the wall, which just made her moan out even more for one of those beasts to claim her already.

“Mmmmmm… tastes like marshmallows~”

While Rarity grunted with a bit lip to partially hide her shameful grin, Spike and Dash merely shrugged and stayed in their positions. The drake kept his own loosened hole firmly against the glory-hole while remaining on his stool (despite the slight discomfort from his hunched angle), and Rainbow was quick to lift her tail and put her own cum-oozing marehood on display for use as well. Even though she didn’t want to disturb her friend from indulging in this sort of depravity for the first time, the pegasus felt compelled to ask while shuddering in need, “H… Hey, Rare?”

“W-What?” moaned out the unicorn as she shivered in antsy delight, feeling one of those dogs smelling her winking pussy through the hole. “I… I’m kinda p-p-preocuppied right now…”

Even though she could tell her friend wasn’t lying, Rainbow sighed sharply and asked, “C… Could you get that spreader bar on the shelf? I really wanna stay in place, and… you can kinda get it easier with your mag--OOOOHHHH!!~”

Before she could finish her statement, the pegasus jolted with a gasp as she felt a random Diamond Dog cock shove itself inside of her without any warning. Even though the unicorn whinnied in disappointment that her friend got another canine so quickly, she quickly complied and lit up her horn. She used her magic to grab the spreader bar from the shelf, and float it over between Rainbow’s hind-legs. Even though Dash was squirming and shuddering in pleasure, she was able to keep her legs spread apart enough for her friend to clamp the bar between them. As soon as the two straps were locked in place, the cyan slut felt absolutely elated to be confined in such an obvious breeding position.

“Th-Thanks, Rares!” Rainbow cried out during her bouts of rutting, her breathing coming out huskily, “Y-You have no idea how much I needed this!”

Rarity simply whined, “I-It’s a pleasure, though I wished I would receive something as well! How long are they just going to look at it?!” True to her word, the Diamond Dogs were rather happily inspecting this new pussy of hers, and haven’t really put forward the advances the unicorn mare was wishing for. While one canine began to eagerly rut the mare beside Rarity’s hole, and another went to stick himself inside of Spike’s puckering entrance, the unicorn’s was left completely untouched while clenching and dripping in dire need.

The drake soon moaned out hungrily, making Rarity’s eyebrow twitch for a moment as she groaned in clear disappointment. “Am I that unattractive? Am I not enticing enough for these unwashed savages? This is. The. Worst. Possible. Thing!” the fashionista complained, throwing a foreleg over her head dramatically, while also biting her lip to quell her immense arousal. She then threw all shame and dignity right overboard as she rammed her ass repeatedly against the wall, knocking with it a few times, before resting her pussy right through the hole in its engorged form. Unfortunately, all that did was cause one of the Diamond Dogs to chuckle in response.

“Seems like this pony slut is really horny,” jeered the canine mockingly, causing Rarity to pout with a frustrated whinny. “Although… it’d be a shame to ruin that pussy. It’s almost like she never had any proper cocks inside of her yet…”

“That doesn’t mean I shouldn’t get one now!” she whined, despite knowing none of the dogs could hear her. However, a loud and undignified groan soon escaped her as she felt two furry fingers sink in between her lips and stretch her pussy out, causing a gush of her own juices to spurt from the teasing sensation. As she gasped in elated shock and writhed against the wall, she heard another round of chuckles from the teasing Diamond Dogs.

“Mmmm… She definitely wants it~” growled another voice. “Heh, I bet she was begging to come down here with that dragon slut. None of those stallions are doin’ it for ya, huh? You little skank...”

Rarity shuddered, her needy pussy spurting another bout of juices as if to answer the Diamond Dog’s query. She was biting her lip hard, and her cheeks were glowing red in growing shame and lust. She may have not known where she would end up until being in the very room she was in, but at that moment, the unicorn felt like she’d come crawling back if she tried to leave now. With how badly her loins were burning in need, and hearing how elated her friends sounded as they both got pounded relentlessly by those knotted members, Rarity felt like she understood their motivations completely.

The very last thing she wanted to do was put herself on the same level as either Dash or Spike, but with each second she spent in pent-up anguish with her marehood yearning for even the slightest penetration, she had a feeling she wouldn’t be too different from them very soon. The real question was if she could give up the rest of her dignity temporarily, and willingly, to have the time of her life. At least, that was what she got from her elated friends and their faces. Dash was drooling like a mindless toy, and crying out to them rather… obscenely.

“Harder! Fuck me harder, you big dog! Make me your breeding bitch!” the prismatic mare moaned in ecstasy, her rump firmly planted against the shaking wall. Rarity herself could feel the tremors along said wall, and it wasn’t helping her case while enduring her cackling crowd. She hated how much all of this was getting to her, but her own trepidations couldn't overcome her dire desperation building up within her.

“F...Fine!" spouted the unicorn in a heated blurt. "I...I’ll be your skank, you sadistic brutes! So please, can you at least now help a lady out!?” she begged pleadingly, almost forgetting that her sound-proofing spell was still active and keeping her words from being heard by them. But with how badly her legs writhed for that cock, her mind was fairly clouded in pure desperation. She wiggled her flank frantically against the glory-hole, and presenting her cunt more pleasingly at the dogs. Since one of them still had his fingers partly in her, this motion only seemed to please her further as she moaned strongly. It was then that she felt the fingers retreat and something hot replace them, poking around her frantically winking entrance.

As the unicorn tensed up and moaned even harder for that teasing object to enter her, her ears twitched as she heard one of those Diamond Dogs say, “Are you a unicorn, bitch? Pump your ass twice against the wall if you are…”

Without hesitation, Rarity frantically rammed her plump rear twice against the wall, which made her marehood dribble even more with her gushing juices.

“Heh. And I bet you have some sound-spell to make sure we can’t hear you, right?”

That made Rarity widen her eyes in realization and wince to herself, hating that she forgot that detail while saying all those crude things. Although, the unicorn knew that it was probably good she had that up in the first place. If she said even a word for those Diamond Dogs to hear, they’d know in an instant that it was her and not just some random mare. However, despite feeling grateful her spell was able to linger in the room despite being so flustered, her heart raced as she heard the canine through the wall continue.

“I’ll tell you what, you little whore pony… If you turn that spell off, and say you’ll be our little fuck-toy… We’ll pump you with more loads than either of your friends~”

That made Rarity’s eyes shoot wide open, and even her friends both looked shocked by that request. Even though both of the other sluts were busy being railed and getting their holes abused by the Diamond Dogs, they were able to glance back at their friend between heavy breaths. Spike wanted to tell Rarity not to do it, since he knew she’d never forgive him the instant she pulled herself out of her orgasmic high. Unfortunately, the only things able to come out of his mouth were shaky moans and whimpers from each plowing thrust from behind. “Ahhhh!!~ D… D-Don’t… Y-You sh… shouldn’t…”

“D-Do it, Rare!” moaned out Rainbow as she endured her own thrusts, with each motion making her swollen womb slosh around with all the cum still inside of her. Before Spike could gasp and speak against it, the pegasus slut cried out between rapid breaths, “Ju… Just put down the spell for a second! It… It’ll feel soooooo good when you get it…”

Rarity could barely look back at her friend’s blissful expression, or the way her eyes rolled back from the canine plowing her so roughly. However, the unicorn trembled for only another moment before lighting her horn, causing the moaning drake to groan in a high-pitched squeal as the sound-barrier dissipated in the room. As soon as she pulled her backside away in impulsive desperation, the Diamond Dogs cackled evilly and waited for her to comply. “Just say it, bitch! Say what you wanna be!~”

Rarity’s throat hiccuped in remorseful fear as she took a deep breath, but she still turned around to point her muzzle towards the now open glory hole. She opened her mouth wide and took a breath, and clenched her eyes shut as she emitted needily, “I… I--”

“AH WANNA BE A FUCK-TOY FOR Y’ALL, YA HEAR?!” bellowed out Rainbow Dash before her friend could say a word, which came out loud enough to make it sound like it came from Rarity’s hole. Even while getting pounded mercilessly by her own pup, it seemed that Rainbow was still skilled enough to use her Applejack impression flawlessly. While Spike sighed in elation (or more specifically, sigh as best as he could while breathing rapidly from his constant ramming), Rarity gawked back at the pegasus shakedly, and saw the cyan slut shoot her a confident wink.

Rarity understood, and couldn’t help but smile thankfully as she lit her horn to set the soundproof barrier back up. As soon as the spell was back up, Rainbow moaned out with a shiver, “Th… There! I… I cashed in the favor…”

“T...Thank you for that,” the unicorn uttered weakly while turning herself back around with her wobbly legs, “though I honestly wanted to use that favor differently. Like… sticking you in a frilly dress, or maybe something more intimate…”

“Too bad!” chirped the pegasus between the heated thrusts she received from her eager canine. “B-But… I would wear some things if… if you wanted to have f-fun with me~”

Rarity wasn’t sure if her friend was being serious or not, but the idea of having some… extracurricular fun with someone like Dash now sounded a bit more alluring than before; especially after the two shared their first kiss with a literal cock between them. Alas, despite how enticing those lewd thoughts about Rainbow became, Rarity used that libido to slam her rear back against the wall, and show her marehood through the hole with a hungry moan.

Fortunately, her patience was finally given its proper reward as one of those pointed cockheads prodded between her glistening lips. Before it could sink in and give the unicorn her well-deserved fill, Rarity shivered when she heard that unknown voice growl out, “You better be ready bitch, because the only thing you’ll ever want from this day on are our canine cocks! We’re gonna make you too loose for any stallion before the day is over!”

And with that, Rarity screamed out the instant that Diamond Dog cock rammed into her, instantly filling her and hitting her already sensitive buttons in all the right ways. Her marehood clenched desperately before getting into a downright spasm, as she cried out loudly and with a high-pitch when she came from the first thrust alone. The pleasure after all the teasing was just too strong, and it fried her mind with sweet bliss from the angry red canine cock spreading her needy twat. Her juices sprayed onto his cock and balls, begging for more as he was practically yanked in by her muscles. The Diamond Dog first grunted in surprise before laughing evilly.

“This pony bitch just came from the first thrust! Stallions really aren’t doing it for you, are they? You need a real canine cock to get your rocks off!” he jeered before pulling out while Rarity was still in mid-orgasm. He then rammed back in hard, causing a high-pitched and pleased whinny to bellow out from her maw. This caused her soon-to-be loosened twat to gush even more, and another smaller climax to crush down on her during her first big one. Her moan came out especially whorishly while pressing her plot hard against the wall, seeking more of this sweet ecstacy these canine beasts were providing her and her friends.

Her tongue was lolling out, and her head rolled back as she took the hard rutting she was yearning for. She may have been the Element of Generosity up above, but down here she was now their bitch. Their slut. Their fucktoy to do as they pleased.

And Rarity couldn’t be happier with it, even as the dog continued to jeer mockingly.

“Cumming again and again, aren’t you? Already got addicted to dog cock, you white pony slut? You better be down here daily then, because we’ll gladly ram that loose pony cunt of yours into submission!” The Diamond Dog continued to mock her while really starting to rail her slutty marehood, making her jizz herself time and time again. Her intensely pleased cries could only be heard by her friends, but her quivering pussy was more than enough proof for the dogs that they already had a new breeding bitch hooked up to their cocks. And as for the unicorn enduring each rapid thrust into her yearning marehood, she was already envisioning taking these brutes up on their offer after all this was over.

Rainbow certainly seemed to agree with that sentiment, seeing how loud she was moaning in the girliest of ways imaginable. It was definitely something that would have embarrassed her on any other occasion, but now she only reveled in it proudly. Heck, if she wasn’t already attached to her Wonderbolt internship, the pegasus would’ve gladly joined Rarity on such a deal; but alas, despite how amazingly thick and virile these beasts were, the fact they couldn’t actually knock her up was more than enough to make the pegasus dream of her fly-boys up in Cloudsdale during her canine breeding.

At least until with a strong spurt, she felt another dumping of canine seed shoot directly into her. She cried out with another climax at the new filling, her tunnel getting another white painting with its hot and virile sperm. The Diamond Dog quickly pulled out though, making sure to paint her flank and even her back as his cock poked through the glory-hole, and squished his member up between her cheeks as some impromptu firing ramp. Soon enough, after enough cum was smeared on her back and even some on her tail, the dog retreated calling, “Pony breeding bitch,” over his shoulder in clear elation. Thanks to the spreader bar, Rainbow’s rump stayed up in wait for another, even though her knees felt rather wobbly. Her leaking cunt was on perfect display through the hole, so the next dog didn’t even need to hesitate before he spread her cunt open again. And while the pegasus groaned out needily in her restrains, the new Diamond Dog began to pound this public use bitch and restart her whorish moans again.

Of course, Dash wasn’t the only slut to receive another filling from one of those pent-up studs. Before the cyan mare was even halfway through her orgasm, Spike bellowed out another hungry moan as his Diamond Dog unloaded inside of his increasingly loosening hole. After that first hefty rope of cum shot inside of him, the canine’s thick knot popped into the drake with enough force to make the dragon’s eyes bulge from his sockets. Of course, as soon as the knot locked inside of his stretched-out hole, there was nothing Spike could do but cry out and shiver from the multiple spurts filling him so thoroughly.

“That’s it. Take it you draconic slut!” the Diamond Dog growled out in approval. “Take every drop of cum from our cocks! You deserve it after bringing along your pony slut friends~”

Spike let out an elated moan in response, and his hole tried to clench as hard as it could around that knot to show his gratitude. Of course, after taking his second knot in a row, it was clear the drake’s tailhole was noticeably loosened for the moment as his clench felt particularly weak around that canine cockmeat. It was more like his ass was a rubber toy now, and the tightness would only result by the sheer thickness of the dog knot that stretched his ass out. Not that this made it any less pleasing for the dogs, who were beginning to line up around one of the three holes in increasing volume.

Spike moaned out loudly as the knot was pulled out by force once again, leaving his ass gaping and twitching through the glory-hole. But before he could even pause to savor the feel of being so loosened so roughly by a canine cock, another one quickly pushed in to fill him once more. All three sluts, ponies as well as dragon, let out their blissful and orgasmic cries in tandem to create a perverted melody along the wet slapping and spurts of cum. By the time Rarity felt that first surge of thick canine cum erupt inside of her, flooding her marehood and womb with so much of that hot and sticky load, her blissful cry was more than enough to make her friends smile wide in satisfaction. Like a switch being turned on with a simple flick, that first filling of the day cemented Rarity as a much closer friend to Spike and Rainbow than she was before. She may have still been an Element, a Fashionista, and an overall prim and proper mare back in Ponyville; but as her legs quivered hard to keep her rear up, and her tail twitched from the feeling of so much cum flooding her from the inside, the unicorn couldn’t deny what she became with her friends beside her. She came into this room as a sophisticated mare, but she was going to leave a stretched-out and cum-filled slut like the others.

And she wouldn’t have wanted it any other way.

Before she even could come down from her euphoric high, she felt the cock behind her get pulled out before her leaking cunt was instantly stuffed with another. Rarity knew that they wouldn’t let her rest, since they promised that the most cocks would actually line up for her hole due to her cooperation. At that moment, Rarity wasn’t sure if she could even keep standing for so long, so she instantly lit her horn and gripped another spreader bar from the shelves. With a resounding click, she locked herself in position, determining her fate as she now couldn’t fall over or pull back.

She shuddered in anxious glee, knowing that was going to keep her pussy pressed through that hole until every single Diamond Dog underground was satisfied. She knew there was a good chance her marehood would end up completely ruined like a common whore’s, and that was something the dogs all too happily reminded her about with each session. However, instead of dreading how she may look by the time this day was through, the unicorn merely writhed in anticipation while savoring all the degrading words that made her heart race in shameful bliss.

“Damn. This pony whore’s pussy is great! It’s gonna be a shame to see it wrecked by the time we’re all done~”

“Eh, she probably has experience! Standing on the streets and letting every stallion fuck her for a couple bits! Seeing how needy she was, she probably did it for free too!”

“Yeah, I can imagine this slut bending over for every cock she comes across! Heck, she might have paid her rent or bills like that! Imagine it guys, her under a bar counter sucking off the barkeep for a drink! Or letting him even fuck her lowly overused holes!”

Each comment was more degrading and insulting than the next, but it set the unicorn’s heart ablaze as she moaned shamelessly in building pleasure. Even though she couldn’t see herself actually doing those things in Ponyville (at least not yet), the idea of breaking those chains of decency and using her body in such a profound way was enough to make Rarity shudder in overwhelming contentment. At that point, she couldn’t even try to deny that she became a slut. And while she endured those increasingly rough thrusts with her chin on the ground and her tongue lolled out, she caught Spike and Dash both grinning at her in confirmation of their plan succeeding.

“We… Welcome to the club, Rare!” Rainbow groaned out while eyeing her with a knowing smirk. “You… You’re gonna love being a slut~”

“Y… Yeah!” chirped Spike in agreement, even though his face was getting clenched in from yet another knot stretching his ass out. “B… Beats monogamy by a landslide, huh?~”

Rarity almost wanted to laugh as she thought back to her previous crushes, now knowing that ponies like Blueblood or Trenderhoof couldn’t hold a candle to what she was experiencing now. She couldn’t be tied down by a single man anymore. Heck, she doubted she could be tied down by most ponies by the time she was finished with these brutes. But at the same time, as she felt her stretched-out walls convulsing from each slide of that Diamond Dog cock currently in her, all that the unicorn could do was moan out and nod her head in guilt-free confirmation. “Y-Yes! All… All I want is… is THIS!!~”

“Good~” purred Dash as she shuddered and pressed her flank back even harder against her glory-hole. “Be… Because you’ll never wanna go back!~”

And for the rest of that day, Rarity felt herself sink into a near constant state of bliss beside both of her friends. Her pussy was constantly in use, never being left empty for more than a few seconds as her pink velvety walls were fucked raw and bathed in canine seed time and time again. Her flank, back, and tail were in no better condition as quite a few Diamond Dogs pulled out to give this slut a proper coating, and mark her with their musky scent as their new Diamond Dog breeding bitch. The mare could only shudder in delight as hot seed splattered over her body, smearing all over her once so pristine ivory coat to give a slightly off-white coloration, while her tail clung together with the dried and fresh seed that was deposited on and into it. The Diamond Dogs also continued to call her every degrading name they could think of while claiming her, but it only turned the once so prim and proper mare up the walls, as these words almost seemed to trigger her climaxes by themselves.

Every sentence of humiliation and degradation that pulled her down to the level of a slut made her cum. Every time doggy seed was dumped into her, it made her cum. Every time a dog knotted her, it made her cum even harder. They only used her body for their own amusement, trying their hardest to ruin it as best as they could in this wild and sex-crazed frenzy. And despite how much Rarity had tried to uphold her image over the years, her heart couldn’t bear to deny what she really desired now; these dark and mysterious caves beckoned to her, and she couldn’t find it in her to not respond back with vigor.

It took several days before Rarity could get back on her hooves again, but the time was more than enough to help her confirm her new feelings. With the aid of Rainbow Dash and Spike (both through deep discussions and physical exploration), the unicorn felt absolutely comfortable with how the two were living their lives now. Of course, that may be because as of today, she was doing the same as well. She may have not been sinking completely into depravity, but she was absolutely content with carrying the same secretive persona that her friend had with the Wonderbolts. But unlike Dash, Rarity made sure that her new ‘friends’ had no idea their new Breeding Bitch was the same mare they were making a lucrative business deal with.

So as she signed the documents in confirmation with Rover in his office, the white mare made sure to be especially careful with covering her backside with her tail. She doubted Fido or Spot would sneak a peek (despite knowing personally how randy they could get), but she didn’t want either of them to see how gaped and loose her marehood still was after her enthusiastic first day with the group. Even though the thought of letting them know was tempting to say the least, Rarity kept her composure while looking over the paperwork across from her business partner.

“Well, Rover,” stated Rarity confidently as she made one last glance through the details. “It seems as if we have a good deal between us. With your mining skills, and my fashion franchise on the rise, I have no doubt that this partnership will benefit both of us greatly.”

“I couldn’t agree more,” said Rover with a confident nod of his own. However, his muzzle skewed a little as he glanced over at Fido, and cringed at the reminder of their first meeting. “And, ummm… I’m really glad that you’re able to overlook that, ummm… incident earlier this week.”

“It’s quite alright,” assured the mare sincerely with a raised hoof and a warm smile. “Spike explained your situation very well, and I completely understand how, errr… important your biological needs are. And Fido?” She looked back at the massive and blushing canine and said in a sincere tone, “Despite what happened, I want you to know that I’m not upset at you in the slightest. The past is in the past, and you shouldn’t feel too ashamed for your incident. Alright?”

Fido still looked a little embarrassed, but he still smiled and nodded back at her with a blush.

“Oh! And speaking of which…” Rarity turned back to her papers and turned to a specific section she added herself. “Rover, did you get a chance to overlook this section regarding your…” Despite her new outlook on promiscuity, the unicorn was able to feign embarrassment and look away while saying in a faux-flustered tone, “ummm… ‘Pony Breeding Bitch’ clause?”

“Oh, ummm… yeah.” Unlike Rarity, Rover’s blush was genuine as he took his copy of the clause in confirmation. “I read through it. But, ummm… could I ask why you wanted to add this?”

“Because the mare you hired happens to be someone very close to me,” answered Rarity while concealing a smirk, not wanting him to know how close she meant. “And she happens to be somepony who doesn’t want her identity revealed to anyone, even to you or your employees. So as long as you have me as a purchaser of your product, I want your legal assurance that no Diamond Dogs will ever know whom you hired as your, ummm… ‘Breeding Bitch’...”

Rover nodded silently, not wanting to press the issue with his newest business client. “Well, I can understand that. And believe me, we’re getting it all set up as we speak. There’s a secret access tunnel being built directly to the room, which'll be finished in a couple days at the latest. And the entrance will have a setup where it can only be opened through a lock with her magic signature. You know, since she’s a unicorn.”

“Precisely,” stated Rarity with a confident smile. “And believe me, I’m very happy that you’re willing to do this for her. I can assure you that as long as the contract stays in order, you’ll have your mare as often as possible given her part-time schedule.”

“Hey, part-time is better than none,” said Rover with a small shrug. “It is a bit of a stretch, but hey! As long as we have a new girl, AND you as a business partner, I’m willing to do what I can.”

“Likewise.” After making sure all her signatures were in the right places, Rarity leaned across the desk and shook Rover’s paw with a genuine smile. “And might I say, I very much look forward to our new relationship.”

“As do I,” said the Diamond Dog as he returned the shake, happy that they’ll have the income they need to really prosper in these mines, while also gaining the relief they do desperately needed. “And be sure to give Spike my deepest thanks.”

“I certainly will.” After the meeting was adjourned, Rarity began to make her leave. However, before she could step out of the office and make her way back home, she paused and glanced back at her new business partner/’employer’ for a moment. “Oh, and one more thing…”

Rover and the other two dogs looked back at her curiously, seeing the mare make the slightest smirk as she said, “My close friend wanted to tell you that she had a few ideas for improvements to be given to the room itself. Mostly design elements and additional products, but I’ll be sure to give you a list she made before her next meeting~”

Fido and Spot shrugged in understanding, but Rover took a moment while narrowing his eyes on the white unicorn. Even though he wanted to say something, or even grin knowingly in realization, the canine was able to keep himself professional before his new business partner. He wasn't going to dare say a word about his educated guess towards her, or any of his employees for that matter, but he still smirked with a nod of his head and said in agreement, "Very well, Miss Rarity. I'll be sure to look over her requests..."
