You WILL Love It.

“Oh Spike! Yes that's it, right there!” Rarity cried, her entire body writhing in pleasure.

The bed beneath her shook with her frantic motions, though the dragon sized bulge that lay beneath the blankets remained motionless. Until several long seconds later when the unicorn began to relax and her breathing slowly returned to normal.

“Oh yes darling that was amazing,” Rarity murmured, the unicorn wiggling her way onto her side of the bed.

A moment later and the blankets lifted slightly to reveal a smirking dragon who licked his lips before settling in next to the pony.

“I’m glad you enjoyed yourself,” Spike exclaimed as he lounged on his side. “You seemed like you needed that.”

“You have no idea,” Rarity gushed. “I had the most annoying customers today and not only that but Mrs Pear Smith came in again just to complain that I didn't have anything that fit her.”

“She is the biggest minotaur I’ve ever seen though,” Spike dead panned.

“Exactly!” Rarity declared, throwing up her hooves. “I’m not a speciest or anything. I just don't have anything that would fit her unique figure.”

“She is quite… buxom. Isn't she?” Spike murmured.

“That she is,” Rarity exclaimed, rolling onto her side. “Thank you again darling. You have no idea how good it feels to blow off a little steam like that.”

“Hey no problem. Sometimes we all need to be pampered a little,” Spike remarked with a shrug.”

Rarity winced. “Speaking of which… are you sure that your okay with me not being able to do the same for you?”

“We talked about this Rarity. I’m just too big for you to do that to me,” Spike replied with a shrug. “Besides. I can still fuck your other holes can't I?”

Rarity blushed, and lightly batted the dragon’s well muscled shoulder with a hoof. “Oh how vulgar. Perhaps what you need is a bit of punishment rather than pampering.”

Spike smirked right back. “Mmm I like the sound of that.”

The unicorn unexpectedly stopped herself and cleared her throat. “No but seriously darling. I really want to do this for you. It is only fair that I reciprocate after all you do for me.”

Spike smiled faintly and ran a claw beneath his lover’s chin. “I appreciate it dear but really there is no need.”

“Don't you dear me mister,” Rarity declared. “I want to do this for you and you will not stop me. Unless of course you’re serious.”

Spike chuckled. “I admit that I’m a little surprised, and frankly quite flattered but you don't have to.”

“I want to,” Rarity replied.

The dragon shrugged. “Then who am I to stand in the way of your wants and desires?”

“Then you will?” Rarity continued, pressing a hoof against the dragon’s chest.

“Of course. Oh and take it slow. Stars know how long it took you to get used to the other things we’ve done,” Spike exclaimed with a wink.

“Just thinking about it is getting me all warm again,” Rarity muttered, a hoof trailing its way between her legs. “The hours spent slowly pushing you inside of my aching holes until they were so full I thought I was going to burst.”

“Mmm fuck Rarity. I don't suppose you could start practicing now would ya?” Spike inquired, the dragon reaching down and gripping his cock tightly in a claw.

Rarity licked her lips. “I suppose I could, though I would temper your expectations slightly. I doubt I’ll be a master after only a few minutes.”

“Just watching you try will be hot enough for me,” Spike replied.

Rarity smiled. “Then I guess I should get moving then.”

The unicorn did just that a second later, moving her way down the bed and between her lover’s legs, drawing the blanket down with her. Where she met the very familiar, and very erotic sight of her lover’s large throbbing erection she adored so much. From the unique pointed tip adorned with a tiny blob of pre to the large knot that Rarity had taken hundreds of times at this point.

Despite that familiarity it still felt exotic to gaze on something so clearly un pony like and knowing she was about to take it once more only made her hotter still. Until Rarity could take it no longer and she leaned forward, giving her lover’s cock a long, passionate lick from bottom to top. Making sure to grab the dribble of pre before it could escape her hungry maw, Rarity wrapped her lips around the pointed tip.

Where she remained for several long seconds, lavishing it in swirling licks, and the occasional slurp. Attention which the dragon himself seemed to enjoy if the throaty moan was anything to go by. Hearing this, Rarity felt a little emboldened, and began to take more, using a hoof to hold the thick dick tightly while she pressed on.

As more and more of his cock slipped past his lover’s lips Spike grew increasingly aroused, as well as hopeful. Despite her poor experience, Rarity had been able to take him in her other holes relatively easily, well at least in the grand scheme of things. Spike muttered a silent wish to whatever deity was listening that this wouldn't take quite as long as the time they tried anal.

Rarity wasn't aware of her lover’s bout of worry as she was continuing to go further down, licking and slurping on his length as she went. She also made sure to keep her hoof pumping, pleasuring what she could not accept into her muzzle in the only way she could. That was until she ran into a rather awkward roadblock, which came in the form of her jaw reaching its limit.

Worse yet, she was feeling the intense need to refill her lungs with oxygen. So with some reluctance the pony pulled back, and while still stroking her lover, took a deep breath. The pair exchanged a slightly worried smile before Rarity went back down, swallowing almost half of his dick in a single practiced gulp.

Pushing further still, Rarity felt a brief moment of pride before something pointed bumped into the back of her throat. Something immediately lurched from deep down in the unicorn’s belly and she pulled back just in time to gag.

“Woah are you alright?” Spike quickly asked.

Rarity waved a dismissive hoof at the dragon. “It's nothing dear. Just startled me is all.”

“Really? Cus for a second there I thought you might thr-”

“That won't happen,” Rarity quickly interjected.

“Well alright,” Spike muttered, laying back against the bed.

Rarity cleared her lungs and went back to her self imposed job, starting things off once more with some minor licking. Only to frown as the odd taste was beginning to grow bothersome, the dragon’s uniquely spicy flavor making her stomach rebel. The unicorn tried to push past it, but it remained a constant irritation at the back of her mind, one which quickly became the least of her worries.

Before that happened, Rarity was able to near the midway point, her mouth now so full of dick that she could feel the tip at the entrance to her throat. It was an uncomfortable feeling, but one that Rarity was able to subdue through no small amount of willpower. The real problems arose when she pushed forward, and was able to feel her lover’s dick begin to enter her throat once more.

For not only could she feel the intense desire to gag return, but worse still, she felt Spike tense up as if he was in pain. Pulling his cock from her mouth, Rarity sat back and quickly regained her composure once more.

“What is it darling?” she asked.

“It's your teeth. Felt like you were biting me,” Spike exclaimed.

“Well I wasn't,” Rarity pointed out.

“That's just what it felt like,” Spike replied with a shrug.

Rarity frowned. “Shall I try again?”

“How about you just stick with the first few inches and stroke the rest?” Spike offered. “We can try again for more another time.”

“If you say so darling,” Rarity murmured.

“It's really not that big of a deal,” Spike quickly exclaimed. “We all have limitations.”

“Limits are made to be broken darling,” Rarity retorted, leaning forward and gripping his cock once more. “And this is one limit that will be shattered.”

Spike smiled awkwardly. “Yay?”

When next the unicorn descended down his length, Spike got the distinct feeling that she wasn't even doing it for him anymore. For the look in her eye reminded the dragon of when his partner was working on a difficult dress, or was staring down a bad guy. It was a look that usually turned him on, for it was a manifestation of her deep passion, and incredible drive.

Now though? Now it was down right intimidating.

Oh well. At least I get a blowjob out of it. Thought the male.

Spike pushed his way into carousel boutique, a tired smile on his face, and an expectant look in his eye.

“Oh honey, I’m home!” he called, uncaring if any customers were around.

A familiar coiffed purple mane poked out from behind a rack of clothes followed closely by the grinning face of the fashionista herself.

“Oh hello darling. How was your day helping Twilight?” Rarity inquired, the mare trotting out to meet her partner.

Spike smiled. “Good. Really good to be honest. She was absolutely swamped with legal nonsense since she announced her desire to run for mayor and really needed an extra claw.”

“Oh? I thought Mayor Mare was going to run again?” Rarity remarked, kissing the dragon on the cheek before trotting past him towards the entrance of her shop.

“Nah she decided to retire after all. Said something about leaving it in Twilight’s capable hooves,” Spike explained, pausing his explanation as he saw Rarity flip over the open sign and lock the door. “Aren't you open for another hour or so, and since when do you chew gum?”

“Just practice darling, and not anymore,” Rarity declared, spitting her gum into a garbage bin. “Now then speaking of practice…”

“You can't be serious. You blew me like three times yesterday!” Spike exclaimed, throwing his arms up.

“But I wasn't able to take you all even once. Nor was I close either,” Rarity retorted. “And I intend on returning every bit of pleasure you’ve given me.”

“Well I…” Spike’s mouth snapped shut the second Rarity strutted up to him, a sultry look in her eye. “Is anyone else here?”

“Sweetie Belle is off with her girlfriends, and I haven't had a customer since noon,” Rarity whispered, rising up onto her hind legs and wrapping her forelimbs around Spike’s shoulders. “So what do you say we have a little fun, darling?”

The way his lover purred the word darling lit a fire in Spike’s belly and within seconds all desire to resist the mare melted away.

“Sure. I could really use a blowjob after the day I’ve had,” he exclaimed with a grin. “Though I’m a little surprised you are still so determined to keep going after everything.”

Rarity waved a hoof dismissively. “Nonsense darling. I may have failed before but each day I’ve become better and soon I shall have all of you once more.”

“Still. You’ve drunk quite a lot of my cum,” Spike muttered, blushing furiously.

“A lady does not spit,” Rarity exclaimed. “Now then, are you ready?”

Spike nodded. “Oh hell yeah. You know me Rarity. I’m always eager to bury my cock inside of you.”

“That is exactly what I wanted to hear darling now just stand right there and let me get to work,” Rarity whispered, nipping the dragon’s ear before falling back onto all fours once more.

“Wait, like right here?” Spike asked, gesturing to the room.

“I cannot wait a moment longer. I’ve been planning this moment for hours,” Rarity implored, running a hoof down his chest. “Unless you are opposed?”

“I wouldn't dream of it,” Spike replied with a grin.

“Good now then, let us free the beast as it were,” Rarity exclaimed.

Spike chuckled as he watched the pony circle a hoof around his crotch, the motion drawing out his erection. It didn't stop there though, as the pillar of dragon dick quickly grew until it reached its full, impressive length. Now covering nearly the entirety of Rarity’s face, the unicorn didn't seem at all put off by its size, and had seemingly only grown hungrier.

She then placed one hoof on the dragon’s midsection before taking his appendage in her magic and its tip into her mouth. There was little need or desire for preamble by either party, as both knew exactly what was going to happen at this point. Despite her previous failings in this department the two lovers were both as eager as ever, and Spike was already looking forward to watching his partner swallow another piping hot load.

Moving forward, Rarity rapidly took the dragon’s length into her mouth, easing herself into it over the course of only a few seconds. It only took a few short bobbing motions before the mare felt confident enough to move a little further, drawing over half of his dick past her lips. At this point her jaw would usually begin to pose a problem, and her teeth would start posing a barrier to her progress.

Not this time however, as the mare opened her mouth wider than before and allowed the tip of her lover’s cock to enter her throat. This time she did not gag, nor did she feel the same primal wave of revulsion that she had a dozen times before. It wasn't easy, but with practice, and a little will power, Rarity had conquered this barrier to her progress.

Swallowing her length, Rarity briefly marveled at the strange sensation that came with having her throat penetrated. That was until she felt a bead of precum splash inside of her and then all of the practice and focused will quickly unraveled. Coughing and sputtering she pulled back, the dragon’s cock popping out of her throat and dangling in the open air.

“What happened?” Spike inquired.

“N-nothing,” Rarity quickly replied, waving a hoof. “Just surprised me again.”

Spike frowned. “Are you sure you want to keep going?”

Rarity shot her partner a look which barely contained all the determination she felt burning in her chest. Her expression seemed to do all the talking required, as Spike’s cock rose just as his contemplative expression fell away.

“Just don't push yourself. I don't want you passing out or something,” Spike murmured.

“Noted,” Rarity muttered.

Spike groaned groggily as he stumbled out of a deep, deep sleep. His limbs were heavy and his mind was at ease, yet some strangely pleasurable feeling was drawing him from his slumber. A feeling that he was becoming more and more aware of as he woke up.

“Whosat, what's going on?” he muttered blearily.

The only response he received was the sound of wet slurping originating from somewhere near his crotch. The noise was also familiar, and combined with the sensations now flooding his body were enough to make Spike realize where he knew them from. A clawed hand gripped the blanket before quickly tearing it off, revealing a white unicorn between his legs, a cock firmly planted between her lips.

For a moment they simply stared at one another, neither moving or saying anything before finally Rarity pulled back. Removing Spike’s cock with a pop, the unicorn wiggled back and awkwardly cleared her throat.

“Good morning darling. I hope you don't mind the unique wake up call,” Rarity greeted.

“Err not really. No,” Spike murmured, his brow furrowing. “I’m just confused is all.”

“Well you see I was lying in bed, unable to fall back asleep when my mind wandered back to last night-” Rarity began.

Images of the marathon fuck session the pair had indulged in flashed before Spike’s mind. Images that included the nearly half dozen blow jobs he had received and the copious amounts of pussy he had eaten. Spike also recalled just how close Rarity had gotten, and just how much dragon cum the mare had guzzled.

“And I couldn't help but wonder if I was one blowjob away from finally getting that fat knot of yours into my mouth,” Rarity stated plainly.

“So you thought to wake me up with a blowjob?” Spike questioned.

“I know you didn't expressly okay it but you seemed fine with my other frequent attempts,” Rarity replied somewhat sheepishly.

“Well I certainly don't mind. Though I think I’ve undone all the work you have just completed by asking for an explanation,” Spike exclaimed with a smirk.

Rarity smiled seductively, flashing her lover a sly wink. “Then I suppose I’ll have to start work a little earlier today.”

Without another word having needed to be spoken, Rarity leaned forward, and gripped her lover’s cock with her magic. Though she knew she didn't have to take things slow, Rarity did so anyway, licking away at the tip while pumping the dragon’s length. Her expertly trained telekinetic aura dexterously teased him back to full length while her plump lips put a fire in his belly.

With one hoof free, Rarity used the open limb to gently rub around the dragon’s crotch in slow, alternating motions. The sensation was a pleasant one judging from how deep her lover’s moans had become, and within moments he was fully aroused once more.

She then leaned forward, taking his length into her mouth where she used her well trained tongue to caress the underside of his cock. While she moved deeper, her magic continued to pump away at a steady pace, ensuring that the entirety of his cock was stimulated. An action which earned Rarity another throaty moan from her draconic lover, as well as a gentle caress.

The feeling of his clawed hand maneuvering her hair from her face made Rarity blush and nearly stop. She quickly got back into the groove of things though, pushing forward while continuing to pump away. All while making sure to suck and slurp on his draconic cock, keeping his pleasure high while still allowing her enough time to take the occasional gulp of air.

Down she went, her lips descending until they passed over the familiar halfway point on his dick. This time there was no pause, or even hesitation as his cock slipped into her throat and began to slide deeper into her gullet. All the panic she usually felt was completely gone, and even her intense gag reflex had been beaten down to the point that it was easily ignored.

With her confidence high, Rarity wiggled her body forward on the bed, breathing through her nose so she didn't have to pull back very far. With a skill she had not possessed only a week earlier, the mare gulped down almost a dozen inches of dragon dick. There she reached her first road block and was forced to pull back only briefly, lest she run out of oxygen.

Once she had steadied herself and filled her lungs with air once more, the pony picked right back from where she had left off. With her throat now stuffed with dragon dick, Rarity felt a brief moment of uncertainty as she stared down at Spike’s knot. It was massive, and not only that but there was still an inch or two between it and her lips, meaning she wasn't even there yet.

Then she remembered all those times Spike had brought her to an earth shattering orgasm with his tongue, and suddenly she felt no hesitation whatsoever. She was going to do this, come hell or high water, a realization that Spike must have come to as well given the excited expression on his face. It was clear in that moment what was going to happen and both parties were eagerly looking forward to it.

So with a hint of fear or regret, Rarity pushed herself hard, until at last her lips pressed against his knot. Her mouth was full, her throat was stuffed, and her tongue had been flattened due to the sheer amount of cock that lay atop of it. The sensation of fullness was intense, though familiar at this point, and though Rarity wanted to rest a moment, she resisted that urge.

Not with the end in sight.

Pulling back, Rarity continued to keep a tight seal on her lover’s cock even while she gulped down a quick lungful of air. With her body’s needs satisfied once more, she went right back down again, her descent ending when her lips pressed against his knot. She repeated this motion over and over, getting used to the feeling of deep throating such a massive amount of dick at once.

It was a familiar feeling at this point, and one that made a certain feeling of pride well in her chest. It also made her curious, and the pony couldn't help but reach toward her neck and touch the bump Spike’s cock made in her throat. One that was so far down her body that it looked ready to enter her belly, a realization that only enticed Rarity even more.

She wanted it all, and at this point she knew that was going to happen within mere moments. All that was left to do was to actually push herself, but not before she got Spike closer to finishing. She didn't want to push him too fast, despite how badly she needed to do this for him.

So she continued to deep throat the dragon dick, using her hooves to steady herself as she maintained her pace. With so much practice now under her belt Rarity was unbothered as the seconds turned to minutes, which in turn began to stretch on. Thankfully it wasn't long before Rarity could feel her lover begin to draw close to his first orgasm of the day.

His muscles began to tighten and his breathing became short, signalling the end. Not only that but Rarity could hear his toes curling as he unconsciously gripped the sheets in his claws. Normally the sound of tearing fabric would annoy the unicorn, but now it only made her that much more prideful.

She held onto that feeling of pride as she worked towards Spike’s orgasm. A goal she steadily advanced on by breaking out all the stops, and really pushing herself harder than she ever had before.

Her seal was perfect, her hooves were in constant motion, and her tongue perfectly massaged the underside of his dick. Every part of her body was working in tandem for the singular goal of getting the dragon off. Including her lips, which upon bottoming out on his cock, slipped a little further up his knot with each meeting.

Until finally they reached the halfway point of the massive bulge, and Spike’s grunting began to rise several octaves.

Rarity knew the signs well at this point, and so with one last titanic push, the mare’s lips stretched a little wider still. Then with surprisingly little fanfare, she took every last inch of her lover’s cock, swallowing his entire length knot and all. Her throat was full, her mouth stuffed to the absolute brim, so much so that she felt like her entire body was being made to serve as a cock holster for the male.

“Unnngh fuck!” Spike cried. “Here I come!”

Bracing herself for what she knew was about to arrive, Rarity took one last feeble breath through her nose before it arrived. With a final, dramatic grunt, the dragon began to cum, and not just a little bit, but more than what Rarity had thought possible. Especially considering she had spent four hours the night before sucking the male off and swallowing every drop.

Despite all that Spike seemed ready to knock up a small village’s worth of females, as the first spurt of cum was enough to fill Rarity’s throat. She could even feel it bulge slightly as the titanic load was shot almost directly into her belly. This was followed by a second, third, fourth and even more after that, each one of which was almost the exact same size as the first.

Rarity could even hear it all slosh around inside of her stomach, the dragon jizz filling her to the point that it felt as though she had just eaten a rather large meal. Then it began to slow, petering out until finally Spike’s knot started to soften, and the male released a long exhale. A blissful expression crossed his face, signalling to Rarity that she had accomplished all she had aimed for.

So with a sense of pride filling her, the unicorn began to pull back, the knot popping past her lips. With its departure, Rarity was able to take a small breath through her nose, and a much larger one once her mouth was no longer occupied by dragon cock. Coughing and sputtering, Rarity slowly regained her composure, wiping her lips free of any remnants she may have missed.

“That was… amazing,” Spike muttered, the dragon laying sprawled out on his back. “Seriously I think I came harder than I ever have in my entire life.”

Rarity took a moment to regain her lady like grace before she crawled up into the crook of his arm, ignoring the slight sloshing noise coming from her belly.

“I’m glad you enjoyed it darling. I was beginning to think that it was going to be impossible,” Rarity remarked.

“Ha!” Spike exclaimed with a smirk. “For you impossible is just a suggestion.”

Rarity smiled, and trailed a hoof over his chest. “Oh you charmer you.”

“Say are you hungry or is it just me?” Spike inquired.

“I’m quite full darling,” Rarity purred. “And content.”

“I can see that,” Spike remarked, prodding the mare’s belly. “You look like Rainbow Dash after she went to that new buffet place with Pinkie Pie.”

“Are you saying I’m fat?” Rarity retorted, pushing herself up on an elbow.

“I err no? You’ve just put on a tiny bit of weight,” Spike replied, only to immediately wince at his poor choice of words.

“Well excuse you mister! I’m not the one with cum so dense in carbs that it could serve as a meal replacement!” Rarity exclaimed.

“I mean you didn't have to swallow it all,” Spike meekly pointed out.

“I told you a lady does not spit,” Rarity retorted, glaring at her lover.

“I uh, fucked up didn't I?” Spike murmured.

“Yes you did. Now you are going to get your own breakfast in order to make it up to me,” Rarity stated.

Spike blinked. “What do you…”

The dragon watched as his lover rolled onto her back, and spread her slightly pudgy legs to reveal her dripping sex.

“Well alright then. Now should I just get right in there or-”

“What do you think darling?” Rarity interrupted.

Spike nodded. “Get right to it. On it dear.”
