Sludge fucks Rarity

After Spike witnessed Sludge having sex with Twilight, he wondered if Sludge might be able to fully show him how a real dragon has sex so that he might achieve his dream of being in a relationship with Rarity, Sludge agrees by demonstrating very explicitly just how he should approach fucking his crush.

Pounding the Pony

Sludge wasn't about to turn down another opportunity to fuck a pony, he never got any action in the dragon lands and any female dragon could kick his ass if he got a little too eager, but ponies were a different story. Sludge and Spike arrived at the boutique and Sludge said "OK Spike, you stay over there in that bush and peek through the window without getting seen and I'll do the rest, got it?"

Spike nodded and went "Got it, stay hidden and learn how I can get into a relationship with Rarity the way a real dragon does it!" Sludge smirked and held back a laugh as he knocked on the door of the boutique, Spike hid in the bush and simply waited, too naive to realize that Sludge wasn't exactly going to showcase the best advice for courting a female, though at the very least he might get to empty his nuts at some point.

A few seconds passed before Rarity opened the door, upon seeing Sludge she gave a smile and said "Well hello Sludge! Nice to see you, what brings you to the boutique today?"

Sludge went "Oh I'll just be browsing, mind if I come in?"

Rarity said "Not at all! Please make yourself welcome!" Sludge went in and Rarity closed the door, Spike waiting in the bush with anticipation, his heart thumping as he breathed rapidly. Spike couldn't help but feel a little bit excited that he was about to see how he should approach finally going to bed with his crush, Rarity. Rarity stood in the middle of the room and said "So, were you looking for anything in particular Sludge?"

Sludge went "Well, I don't suppose you'd blow me would you?"

Rarity obviously hadn't been listening properly as she said "Well I suppose I should be able to find something in here that... hang on a second, what?"

Sludge grinned as his large cock began to emerge, slowly hardening with every throb, he took hold of his member and stroked it to encourage it to a full erection as he said "You heard me Rarity, get over here and suck on this sturdy fuck pole of mine like a good little pony and I'll give you a nice big helping of virile dragon spunk right into your soft silky mouth..." Rarity was stunned to say the least, she hadn't really expected Sludge to come to her with such an explicit request of a blow job right out of the blue, though one part of her was actually flattered and maybe even really excited at the prospect to a point where she actually kind of wanted to do as he asked.

Rarity cleared her throat with a blush on her face as she eyed Sludge's over-sized package, her mouth watering and her pussy aching before saying "Well Sludge, I'm flattered that you want to experience my mouth, plus you're not the first to be so bold as to be so direct... many a stallion and even a few mares have approached me with the intent of getting to share a bed in my embrace, though I must say you are indeed the first dragon to ask for some fun"

Sludge raised an eyebrow and went "And...?"

Rarity let out a breath and said "Well, despite being rather prudish, I couldn't call myself the element of generosity if I didn't at least entertain the idea so long as you are not so vulgar with your wording from here on out, so sit back and relax, then let me do the rest", Sludge did as she said and sat back with his legs open, ready to get his dick sucked. Spike just watched in awe, it slightly bewildered him that if he had simply just asked, then Rarity might not have hesitated to suck him off. Rarity trotted over to Sludge, a small twinge of apprehension as she truly took in the enormity of cock she had to wrap her lips around just to satiate her lust as well as prove that she could be very welcoming and accommodating, even in matters of the bedroom where the best way to make someone feel at peace was to allow them to engage in the pleasures of the flesh. Rarity planted a couple of tender kisses against Sludge's pulsating shaft, before moving upwards and swirling her tongue around his tip before slowly allowing a good inch of his member into her mouth and softly began sucking.

Sludge let out a sigh of pleasure and went "Ooh yeah... not a bad start at all...", Sludge gently stroked Rarity's mane, Rarity leaned into his touch and looked up at him while batting her eyelashes to look as cute and adorable as possible, well aware that visual pleasure was just as important as the physical pleasure. After a few seconds Rarity closed her eyes and regulated her breathing so that she could comfortably descend, pushing herself down to get more and more of Sludge's dragon dong into her mouth, upon getting halfway down his dick she let out a small gag which told her that he was now poking the back of her throat and that she had gotten as much of him in her as she could handle. Rarity kept up her sucking and began bobbing her head up and down, alternating between holding the cock in her mouth and making quick and short back and forth movements and pulling back until her lips were at the tip and then plunging all the way back down again. Sludge groaned at her expert oral skills and laid his claw on her head "Mmmm... fuck, you ponies always have such soft and moist mouths, perfect for caressing dick. A female dragon is more likely to tear a dick off if they take it into their mouth..."

Spike made a mental note of everything he was seeing, he wanted to make sure that when it came to doing this to Rarity that he would do it the dragon way. Rarity lit up her horn and used her magic to fondle Sludge's balls, she was enjoying tending to his thick hard monster of a cock, but she didn't want to spend too much time in her boutique just blowing him. Sludge could feel an orgasm slowly rising in his groin, building and building the more he immersed himself in Rarity's ministrations, though he felt like now was the perfect time to be a little rougher, just like a real dragon. Sludge gripped Rarity's head in his claws, making Rarity let out a muffled yelp from the unexpected action, then without warning he rammed her all the way down on his dick and started pumping her up and down like she were some kind of unfeeling flesh light. Rarity was so surprised that she couldn't concentrate on using her magic, meaning she stopped fondling his balls and glared up at Sludge for so savagely taking advantage of the situation to claim her throat without even asking.

Rarity continued to gag and cough, her body trying desperately in it's futile effort to expel the intruder, Rarity didn't have the strength to push herself off and so had to sit there and take it whether she liked it or not, being forced to repeatedly deep throat Sludge wasn't exactly part of the plan. Sludge groaned and sped up his assault, despite Rarity having her eyes shut tight mascara stained tears ran down her face, cheeks red from lack of oxygen as her muzzle was pressed to Sludge's crotch over and over and over again. Sludge groaned as he finally reached his limit and pushed Rarity down one final time and held her there as he blasted his load down her throat, Rarity glared at him intensely still unable to remove herself as her throat accepted defeat and, rather than trying to force the cock out, began swallowing down the sticky substance and massaging his length. It seemed Rarity's body had learned to deep throat without really meaning too, because Rarity now felt oddly more comfortable having her face full of dragon cock than before. Sludge relaxed and finally let go of Rarity's head, which allowed her to practically launch herself away from his throbbing erection and gasp in as much air as he lungs could take, when her breath was steady again she went "Well Sludge, while I can say that the feeling of your seed in my stomach is rather nice and warm, it was very rude of you to force me into swallowing without asking!"

Sludge chuckled and said "Oh I'm sorry Rarity, maybe I could make it up to you? After all, once is never enough for a dragon, I don't suppose you'd let me have some fun with a hole that, perhaps, is more specifically designed to handle my equipment?" Rarity knew exactly what Sludge was talking about and although she didn't show it, she had to admit that the idea was incredibly enticing, the only thing that really concerned her was his size.

Rarity gulped and said "Um... well... do you think you'd fit?"

Sludge shrugged and said "Only one way to find out really, you up for it?"

Rarity looked around nervously, almost as if expecting several ponies to be watching through the windows, then turned around, widened her stance and moved her tail out of the way to give Sludge an unobstructed view of her dripping pussy. Blissfully unaware that Spike was watching, she said "Alright alright, but make it quick OK? I can't spend all day having my brains fucked out by a dragon!" Sludge simply held back a laugh as he got to his feet and got behind Rarity, gently clasping his claws onto her hips and preparing to penetrate her drenched folds, which proved to be easier said than done. Size difference did present a slight problem, attempting to get something decently large into a space that was a fair size smaller was never going to be an easy task to begin with, but the slickness of both of their respective sexual organs caused Sludge to keep slipping up in between her ass cheeks or down in between her legs each time he began to press his tip against her entrance. After a few seconds of not really getting anywhere, Sludge growled and used on claw to steady his erection and pressed as hard as he could, his tip finally popping into Rarity's tight pussy.

Rarity gasped and went "Are... are you in?"

Sludge, confused, went "What do you mean?"

Rarity said "Well it's just that... you're already stretching me just a tad more than any cock or strap-on I've ever taken... are you all the way in?" Rarity knew the answer, but she was hoping that at the very least Sludge would take the hint that he'd need to be delicate and not just ram it in the way he had at the end of the blow job she had given him, she was wrong. Sludge grinned, now that he was in, all it would take is some pushing and his cock would be entombed in some perfect pony pussy.

Sludge put his claw back on Rarity's hip and with one powerful thrust, slammed his dick in down to the base in Rarity's warm, moist and unprepared fuck hole. Rarity screamed as she was so suddenly filled, the walls of her love tunnel rippling and squeezing along the length of reptilian fuck flesh that was making her feel so profoundly full, more full than she had ever felt in her life. Sludge grinned as he finally answered her question with a cocky sarcastic tone and said "Yep! I'm all the way in!" Rarity's eyes were wide and her mouth agape, but didn't make a sound, she was too busy trying to figure out if what she was feeling was incredible pleasure or incredible pain. When Sludge began thrusting, Rarity moaned and whimpered and came to the conclusion that what she was feeling was an uncomfortable mixture of intense pleasure and excruciating pain. Through gritted teeth, Sludge groaned and said "Fuck... are you ponies always this fucking tight? Geez, it's taking so much effort just to pound you...", Rarity couldn't reply even if she wanted to, she was still struggling to comprehend her body too much for her brain to be preoccupied with anything else other than trying to get used to every sensation that her body was being barraged with as Sludge fucked her senseless.

Sludge found fucking Rarity more and more comfortable as time went on, as her insides contorted and conformed to the shape of his cock to make taking him more bearable, Sludge leaned forward and pushed Rarity's head to the floor as he began thrusting away at her pussy like there was no tomorrow, which finally brought Rarity back to her senses as she groaned "Aah... what the fuck are you doing?!"

Sludge growled and said "Fucking you, what's it feel like I'm doing?" Sludge just ramped up the strength of his thrusts, his hips practically crashing into Rarity's butt each time with a resounding clap, the way Rarity's cunt was caressing his length was bringing him closer to orgasm than he expected.

As Rarity felt his cock throbbing more and more with each passing second she went "Wait... w-wait! Are dragons...ugh... and ponies c-c-compatible?! Like, genetically speaking?!" Sludge just shrugged and carried on, which made Rarity worry as she cried out in desperation "You don't know?!?! Pull it out! Pull it before you cum! Don't cum inside! I don't wanna get pregnant! I'll let you cum anywhere you like! My hooves, my mouth, anywhere!"

Sludge grunted and said "Anywhere?" Rarity nodded as fast as she could, Sludge had to smile as Rarity failed to realize the loophole in the promise of letting him cum "anywhere", Sludge increased the power of his thrusts as he said "Fair enough!" Rarity gasped as Sludge buried himself in her cunt to the hilt with his tip pushing against her cervix as he blew a thick hot load which instantly triggered her own orgasm, making her scream as dopamine flooded her brain with feelings of ecstasy. When the both of them regained their breath, Sludge pulled back and tugged himself out of her ruined fuck hole as he said "Well, you did say anywhere!"

Rarity shakily stood up straight and said "Will... will I have a baby?"

Sludge went "Nah probably not, I don't think dragons and ponies can mix like that"

Rarity let out a sigh of relief as she went "Well then, if you would be so kind as to leave, then I might be able to clean myself up and seem presentable for the rest of the day"

Sludge laughed and said "You're kidding right? You're not serious right? We're not done"

Rarity went "What? You just came and I'm perfectly sated, what else could we possibly do?"

Sludge raised an eyebrow, prompting Rarity to think where else he could possibly stick his dick, then it dawned on her that there was one hole on her body that he had yet to conquer. Mortified, Rarity just said "Oh goodness no! Absolutely not! It's not proper to have things in the... the back end, certainly not!"

Rarity got the shock of her life as Sludge grabbed her, pushed her onto her back on the floor and snarled at her as he went "I'm sorry Rarity, it seems you've misunderstood the situation, I'm not fucking asking to have your ass, I'm telling you: I'm taking your ass!"

Rarity's eyes went wide and pleaded with him "No! No you can't! I... I... you just can't!!!" Rarity screamed as Sludge angled his dick at her untouched pucker, having never even been teased, let alone penetrated. With no regard for Rarity's feelings, Sludge aggressively rammed himself balls deep into her ass hole, hell bent on screwing her no matter how much force and resistance her butt put up in some vain effort to cope with his dong. Rarity's scream died in her throat as she went limp and simply accepted that this was happening whether she liked it or not, tears streaming down from her eyes.

Sludge grunted as he plundered her booty, his balls slapping against her ass cheeks as he gradually got Rarity's rear to loosen up and stretch around his girth, molding her rump to make it as efficient at pleasing dick as the other holes on her body. All the while, Spike had been watching, making sure to take notes on all the important facts of the courtship practices of a real dragon, he'd make sure he knew exactly how it should be done when it came to the ultimate test of getting Rarity to like him. Truth be told, Sludge was somewhat disappointed with the anal sex, Rarity had stopped putting up a fight and so had her body, making fucking her ass far too easy and less of a challenge. Sludge figured that there wasn't really anything he could do if Rarity was failing to respond to her first ass reaming and decided to go at full speed and strength with his thrusts, pushing himself to the sweet release of orgasm. Sludge let out a breath of relaxation the second his third load splattered against the walls of Rarity's insides, when he was finally drained of his spunk, he pulled out of Rarity's practically destroyed ass hole and sat back to bask in his after glow as his seed spilled out of her.

Then it was Sludge's turn to be shocked, as before he could even begin to go soft, Rarity turned around cackling maniacally with a wild look in her bloodshot eyes and began to roughly jerk him off, she grinned at him and said "Having fun?!?! You like this hoof job you dirty bastard?!?! Come on, you've got one more load, I fucking know it! Look at those fat churning balls and tell me you don't have one more left in you! You fucking raped me, forced me into anal sex, took my anal virginity without my consent and you don't have any fucking more cum to give?!?! Do it you filthy shit! Fucking cum all over me!!!" Sludge was far too surprised by this sudden stimulation to hold himself back to prolong the experience and groaned as his cock fired off ropes of jizz all over Rarity's face, all over her eyes, horn, mane and muzzle. Rarity let go of his cock and just fell to the floor giggling like a mare gone mad.

Sludge sighed in satisfaction, he didn't fully realize that he did actually need to blast off one more time before he was fully spent. Without a word of thanks, Sludge got up and left Rarity to sort herself out as he simply walked out of the boutique to be greeted by Spike.

Spike went "Whoa... that wasn't what I was expecting at all!"

Sludge chuckled and went "So, what did you learn my boy?"

Spike went "Ask them nicely for a blow job, then be sure to force them to take it into their throat and swallow your spunk. Fuck their pussies as rough as possible no matter how much they ask you to slow down. Fuck their butts even if they say no and they'll thank you for how much you hurt and pleasured them with a friendly hoof job!"

Sludge smiled and went "That's my boy!"

Thank you LegenFlife04 for this story idea! I hope you enjoyed it :)

Prologue

Sludge and Twilight had just finished having some rather rough sex, unaware that Spike had witnessed the whole thing. Rather than feeling disgusted, Spike was somewhat interested because he knew how sex worked the pony way but Sludge had yet to show him the way that a dragon has sex... it looked a bit forceful all things considered. Spike was undeterred however, so the very next day when Sludge lumbered out of the bedroom and Twilight was still recovering from the hard pounding she had received, Spike immediately went up to him and said "Dad... can you teach me the dragon way of having sex?"

Sludge looked at Spike with shock and said "Um... Spike, I'm your father... plus, I'm not really that way inclined so..."

Spike clarified and went "No no no no, I mean... like, can you show me how a dragon would fuck a mare that he likes?"

Sludge breathed a sigh of relief and went "Phew! You scared me for a second there, sure I could show you, you'll have to watch from some kind of hiding place but I could show you how we dragons do it. Who did you have in mind?"

Spike bit his lip nervously, he knew exactly what would be happening if he said this pony's name but if he wanted to love her like a real dragon would then he figured he could live with Sludge's teaching method this one time. Spike took in a deep breath and said, very confidently, "Rarity".
