“Dinner”

~-~-~-~

“Belle? You almost ready?” Spike asked, ducking through the doorway.

“Almost, Spike… Just gotta get this damned curl to set… Aah, there we go.” She teased the last strand of hair into place, turning to smile at her husband. “Do I look okay?” She certainly did. If they didn’t have somewhere to be, Spike would have taken her on the spot.

“You look divine, love.” Spike smiled, leaning in to kiss his wife on the cheek. She blushed and nuzzled his scaly neck affectionately. In light of their delay, though, they couldn’t afford to get into anything more. He spared a quick swat at her flank as they left the bathroom, getting a teasing smile and a playful yelp in return. They left their home, walking quickly towards Rarity’s boutique.

Spike and Sweetie Belle had married a few short years ago, not too long after Sweetie Belle had finally moved out of Rarity’s house. They had, of course, been fooling around for much longer than that, but as they both matured, feelings began to develop. Within Ponyville, their wedding was a happy occasion, cause for celebration and merrymaking… But elsewhere, scholars and officials disagreed with a unicorn marrying a dragon. They called it ‘uncouth’ and ‘against nature.’ Not that they understood how the two of them felt towards one another…

It had actually been quite the fiasco, getting the marriage sanctioned by the government. Mayor Mare was all for it, having lived half of the two parties lives in the same town that they grew up in, but the officials wouldn’t hear of it. They even went so far as to arrest Spike to prevent the wedding from happening. Thanks to a timely intervention by Celestia, however, the whole thing had been looked past, legalized, and even attended by some of the officials who had originally denied them. The catch being they had to stay in Ponyville. Other towns or cities would most definitely have ostracized them, and they wouldn’t be happy.

They honestly didn’t mind at all. They were with friends and family, able to live with the same community that had fought for them to be together. The other crusaders visited often, Twilight and Spike were still as close as ever, and they were free to pursue their love as openly as ever. Spike smiled down at the ring settled on Sweetie Belle’s horn, his claws spinning his own simple band around slowly… The rings served as a reminder of the pain they had endured to be together… He loved her with all his heart. His wonderful, talented, loving wife.

Sweetie Belle had discovered her talent in singing not long into middle school. Together with a local DJ, the two of them made music, and were rather well-known throughout Equestria. They lived comfortably in a small home, and had plenty of free time to just enjoy life. It was during the downtime inbetween recording albums that they had agreed to meet Rarity for a home-cooked dinner. Sadly, singing did not correlate well with cooking, and Spike had rapidly out-grown the small kitchen. They ordered out most nights. The prospect of enjoying a hearty meal cooked by none other than Rarity was both promising and appetizing.

“I can’t believe we’re late.” Sweetie Belle muttered, shuddering a little thanks to the late-autumn cold. Spike absently laid a claw on her back as they walked, hardly having to bend his elbow ninety degrees. Sweetie Belle had grown tall, but not nearly as tall as Spike. He easily towered over the heads of every other pony, and had to stoop quite a bit to fit through some doorways. Thankfully, he could still stand upright in many homes, but it seemed even that would soon escape him.

He was tall, but very lean. His muscles were beginning to grow in, but not at a gross rate. Unlike others of his kind, he did not have wings, and his spines had remained rounded for the most part. Only a few near the end of his long tail had grown into spikes at all. His fire still remained green, with sprinkles of magic interspersed, and could relay messages to and from Celestia and other prominent members of Equestrian royalty. Luna and Cadance, primarily, though after he moved out of Twilight’s home, those messages hardly came and went at all.

“It happens. Rarity will forgive us.” Spike smiled down at Sweetie Belle, though the two of them picked up their pace a little. When they finally pushed through the door to the boutique, Rarity trotted around the corner with a wide smile on her face.

“Darling! So glad you could make it. I feared you wouldn’t be coming, I was prepared to visit your place!” She threw her hooves around Sweetie Belle’s neck, laughing together.

“Sorry, sis… We got a little carried away with… Aah…”

“Say no more, darling.” Rarity pulled away, going to Spike next. “Always a pleasure, dear. How are you?”

“To be honest?” Spike hugged Rarity with a smile of his own. “Bored. Both of us are. Thanks for inviting us over.”

“Anytime, dearie! Anytime!” Rarity’s smile beamed up at him as she pulled away. “I took the liberty of holding off until you arrived, but I do have a salad prepared to munch on if you’re hungry.” The growling from Sweetie Belle’s stomach made all three of them blush a little. “Aah. Right this way.” Rarity smiled and led them into the kitchen/dining room, sweeping a hoof out over the simple spread. “Help yourselves. Spike, I know you enjoy gems, so I’m happy to let you eat from my stock. Don’t worry, I’ve more than enough to get me through the next few years at least.” She nudged a bowl filled to the brim with sapphires and rubies, amethyst and emerald. Spike’s mouth watered, but he knew better.

“Thanks, Rarity. But I ate before I came over here.” Of course, ‘ate’ could be used in more than one fashion.

“Oh? Dietary consideration from a dragon. That’s new.” Rarity teased, nudging him with her hip before trotting over to the oven. “Well, if you feel the need to snack, help yourself.” She smiled over her shoulder before setting in on dinner. Sweetie Belle excused herself and dug into the salad, eating her fill of the fresh, crunchy greens. Rarity didn’t take long to prepare a delicious-looking pasta, and over wine and istallion, they all chatted.

The topic of conversation moved from fashion and the boutique to Sweetie Belle’s latest music, on to local politics and even the fiasco a few years back involving the dragon and the younger unicorn. Rarity’s business was flourishing lately, and she had even hired a few other helpers. One such stallion was absent from the dinner, when Spike thought it would have been all but natural for him to attend. In fact, the absence of Rarity’s love interest was both intriguing and socially awkward to discuss… Spike was pondering a polite way to mention the pegasus’ absence, when Sweetie Belle managed to steer the conversation around to the same question he had been meaning to ask.

“Where’s Cross Stitch? Is he managing another showing in Canterlot?” She leaned over and asked quietly. Rarity seemed to have been expecting the question, as the expression on her face was both wistful and slightly melancholy.

“Alas… Pegasi are not known to stay in one place for long… Either physically or emotionally, it seems…”

“Oh no…” Spike groaned, leaning in a little more. “What happened?”

“Aah… Well, I… Ahem… Caught him.” She sighed, suddenly very interested in the tablecloth. “With another mare…”

“Oh my goodness, he cheated?!” Sweetie Belle blurted, sitting up straighter in her chair. “That’s horrible! With who?”

“Surprisingly enough, with Roseluck… The two of them met with that tacky little green ensemble I had received on commission, and had been fooling around behind my back over the course of it’s development… The bastard had the nerve to do her right on my knitting chair, too! Ooh, the nerve.” Rarity was flustered now, her flanks quivering as she grit her teeth.

“What’d you do, then?” Spike asked. “I mean, I hope you kicked his skinny little tail.”

“Picked him and her up, tossed them right out onto the street. He hadn’t even sheathed, and she was still spread wide. I let the whole town see them together.” Rarity flipped her hair over her shoulder, straightening her back. “I’m surprised you didn’t hear about it. The police promptly arrested them both for indecent exposure. The whole legal fiasco lasted up until just yesterday… My, I’m surprised you two hadn’t heard about it!”

“As am I…” Sweetie Belle muttered. “I’m sorry to hear about him, though… I thought you two would be destined to be together… You know, given his talent…”

“Oh, nothing to worry about… He’ll be stitching saddlebags for Cloudsdale’s weather team for a while now… And I burned Roseluck’s dress before her very eyes. I haven’t seen her since last week.” Rarity sighed, staring at the tablecloth once more. “Truth be told, though, the whole thing has been far more stress and anxiety than he’s even worth… One month of being tied up with the court and civil disputes, why, I’ve hardly even had the time to-“ She stopped then, her gaze flickering up to both of them, her cheeks flushed a bright red. “Sorry. ‘Tis improper for a lady to speak of such things.” She muttered.

“Speak of what?” Spike asked, arching an eyebrow. “Rarity, you know you can talk to us… I mean, I am your brother-in-law…” He leaned across the table, resting a claw on her hoof. Sweetie Belle’s expression was the same of concern and worry.

“I know, Spike… I suppose there’s no harm in it… I mean, you two know enough about it by now…” She sighed and raised her head. “For one whole month, I… Well, I haven’t…” She struggled with the next word, her mouth opening and closing several times.

“Get on with it,” Sweetie Belle groaned, rolling her eyes. “No need to be shy about it.” Rarity huffed as if she were annoyed with being pushed into action, but closed her mouth and blushed deeper.

“I haven’t… Released.” Spike and Sweetie Belle both blinked for a few moments.

“What, you mean… You haven’t had sex?”

“Spike!”

“Oof! What?!” He grunted as Sweetie Belle jabbed his side. Rarity became transfixed with the tablecloth yet again, her cheeks so red that Spike thought they’d burst into fire before long.

“To but it bluntly, yes…” She sighed. Sweetie Belle shot him a glare that said ‘we need to work on your manners, mister’ before turning her attention back to her sister. “With court and work and everything all piling up at once, I haven’t been able to find anypony else to help with… You know. Goodness, I haven’t even given myself the time to handle the situation myself. Seeing you two just reminded me that it’s been a whole month since I… Had sex…”

“Hmm…” Sweetie Belle mumbled, her hoof rising to cup her chin.

“Belle?” Spike asked. “I know that look… What are you thinking?” He leaned away from her, wondering what his wife had in mind. The ring on her horn glittered as she looked up, her lips spread in a devious grin.

“No-thiiiing…” She tried to sound innocent. Spike knew that smile to be anything but.

“Don’t tell me you’re-“

“What? If she doesn’t mind, then I certainly don’t… Heck, it could be fun!”

“Belle, we’re married.” Spike groaned, rolling his eyes.

“Exactly. You love me. Fucking my sister isn’t going to change that at all.” She slipped off of her chair, grinning still.

“Sweetie Belle! That is no way for a lady to talk!”

“Oh, come off it, Rarity.” Sweetie Belle rolled her eyes. “I’ve heard you use more improper words than that. These walls aren’t as thick as you might think they are.”

“Y-you heard me with other stallions?!”

“I’m surprised the neighbors didn’t hear you.” Belle huffed, smiling at Rarity’s reaction. “You really ought to bite the pillow more often. It keeps you from screaming too loud.”

“I-I… Whaaa-“

“Trust me, Rarity.” Spike groaned. “When she gets like this, there’s not stopping her…” He sighed and let his gaze settle on Rarity once more. She was flustered, her cheeks flushed, her mouth hanging open. Spike had always had a crush of sorts on Rarity. He had always written it off as a young dragon’s yearning, but the feeling of infatuation had persisted. He loved Sweetie Belle, that much was for certain, but he was still attracted to Rarity… In fact, the night Sweetie Belle had dyed her mane the same color as her sister’s was one of the most sexually prominent memories in Spike’s mind.

“But… But, I-… What if-“

“Oh, come ON!” Sweetie Belle groaned. “Follow me. Both of you.” She clomped away angrily, leaving the dining room and heading for the nearby staircase. Hesitantly, a very shy Rarity and an awkward-feeling Spike followed. Sweetie Belle led them upstairs, pushing her way into Rarity’s bedroom smoothly.

“H-hey…” Rarity protested, but a magical shove from Sweetie Belle urged her into the room in short order. Spike followed after, sighing to himself. Rarity stammered as Sweetie Belle picked up a nearby chair and floated it towards the foot of Rarity’s massive, four-poster bed.

“Look, Sweetie Belle, I know you mean well, but you can’t just barge in here and-“

“Rarity, shut the fuck up.” Sweetie Belle groaned, exasperated as she hopped up into the chair. Rarity stuttered, but shut her mouth, staring incredulously at Sweetie Belle. “Spike’s wanted to have you for a long time. You know that, right?” She asked, slowly settling down.

“Eer…”

“I thought it was kinda shitty that you’d never give him what he wanted.” She continued, smiling coyly.

“But, he was always like a little brother to me!” Rarity protested. “I couldn’t think of him like that! Not ever! A-and, even when he started to grow older, he fell in love with you… How could I intrude on that?”

“It’s just unlike you, is all…” Sweetie Belle teased. “Usually when a stallion fawns over you, he’s in your bed before you can even finish hemming his suit pants.”

“Now, Sweetie Belle, that’s hardly-“

“Rarity, what part of shut the fuck up is so difficult to understand?” Sweetie Belle groaned, rolling her eyes again. Rarity shut her mouth, but she looked cross. “You just told me and my husband that you haven’t had sex in a month. To me, and my twisted little brain, that means you want to get off. Well, Spike most certainly has the equipment to deliver, and you’ve got a need that requires some fulfilling.” She waved a hoof as she spoke, connecting dots in midair. “So, that tells me, you want to fuck Spike. Either that, or you want me. I’m not into mares, but I’d be willing to give it a shot-“

“No. Thank you.” Rarity cut her off. Sweetie Belle grinned and settled down into the chair a little more, her hooves tucked up underneath her.

“Well? Either you want it or you don’t. I know Spike does. And hon, I honestly don’t mind. I kinda wanna watch you fuck my sister.”

“Belle, that’s… Wow…” Spike rubbed a hand along his spines, feeling extremely awkward. Here was his wife telling him to take his childhood crush, and said crush appeared to be seriously contemplating it… In fact, when she looked back at him, he could see many fiery emotions in her eyes.

“So do it. Right now.” Sweetie Belle rolled her hoof at the two of them. “And yes, I will be watching. I have to make sure my man doesn’t do a better job on my sister than he did on me earlier today.” The previous lovemaking session had been cut short by the need to be decent for the dinner date, but that only meant Spike was worked up and ready to blow. The desire began to rise slowly, his blood pumping to fill his member slowly. The pink flesh emerged from his sheath, slowly rising.

“Aah…” Rarity moaned as she spotted the exposed dragon cock, and Sweetie Belle grinned.

“Look at that.” She teased. “He’s even ready for you. Go on, Rarity… Why don’t you give it a lick?”

“I…”

“No excuses. Look at him, Rarity… He’s getting hard just thinking about it.”

“Spike, please… This is hard enough without you waving that… That…” She trailed off, her eyes fixated on the pulsing shaft of dragon flesh.

“That beautiful, juicy, dragon cock just waiting for you?” Sweetie Belle cooed from her chair. “Come on, Rarity. Go give it a lick. Look at him, he’s just dying to give you a taste…” Rarity’s mouth worked open and closed a few times, obviously trying to gather the courage to approach Spike. Awkwardly, he stood there, his erection bared to the room, two white unicorns looking at his predicament. Both of them with equal amounts of desire in their eyes. He watched, transfixed, as Rarity slowly approached him…

“This means nothing.” She affirmed, managing to tear her gaze away from his twitching member. She looked him in the eyes, her own filled with desire, pleading and pent-up desire. “Just one friend helping another, as far as I’m concerned.”

“Right. Nothing funny about it.” Spike confirmed, raising his claws in defense. “Just… You know… Help me out, and I’ll help you…”

“Okay… So, then… We… We don’t have to hold back?” Sweetie Belle snickered at Rarity’s hesitant question. She got a glare from Rarity, but Spike was busy staring incredulously at the white unicorn before him.

“Wh… What do you mean, ‘don’t hold back?’” He panted.

“I mean…” She swung her gaze back around to him, this time her eyes alight with passion and lust. “We don’t have to hold back. As in, anything goes.”

“L-like…”

“Like I wanna see you pull her mane when you shove it in.” Sweetie Belle chimed in. “Smack her flank and call her a dirty little whore. Flip her over and make her choke on that delicious cock while you shove your tongue into her.”

Rarity’s indifferent shrug said it all. Spike gulped, though his heart was hammering faster than anything.

“Right then…” He muttered, flexing his muscle to make the tip of his cock jump. “What are we waiting for?” Rarity grinned at him for a moment before leaning forward. Her first hot breath washed over the pink flesh, making Spike groan. She slowly pushed her tongue against it, making the whole thing move back an inch or so, before slowly and very deliberately dragging her tongue all the way up it.

“Aah… She’s a pro, I can tell…” Sweetie Belle moaned. Spike glanced up from one provocative display to another. His wife was now spread open, one leg draped over the back of the chair, her hoof slowly grinding a circle against her exposed center. “What?” She teased, quickly licking her own juice from her hoof before returning. “I might as well enjoy myself, right?”

“Belle, if you’re gonna commentate-“

“Let her.” Rarity panted. “It… It’s helping… No holding back, right?” She smoothly returned to her eager licking, this time going from the base of his member all the way to the twitching tip. Her saliva glimmered on the pink, sensitive flesh, making Spike shudder. His legs nearly gave way, but he managed to stay standing… At least, until Rarity pushed him in.

“Aah!” He gasped, leaning back against the wall. His claws fell to her mane, pushing through the magnificent purple strands as she pushed her mouth further down onto his cock.

“That’s the way, Rarity…” Sweetie Belle groaned. “Cup his balls… He really likes that…” Obligingly, Rarity raised her hoof up to gingerly cup Spike’s swollen testicles, making the poor dragon shudder some more. His breath left his lungs in pants, and Rarity smiled even with her mouth full of him. She slowly pushed her head further, and she even resisted the gag when his head hit the back of her throat.

“Oooohh… That feels incredible…” Spike’s eyelids flickered as Rarity pulled back, sucking to add pressure to his massive erection. Sweetie Belle’s groan matched his own, and Rarity moaned as well. Together, the three of them shuddered. Rarity moved back down once more, her lips gliding along his shaft with ease, thanks to the thin layer of saliva she trailed with it. She repeated the motion once, twice… Again… And again… Spike was soon drooling as Rarity’s head bobbed back and forth as fast as she could manage, gagging now and then, but still moving him in and out.

“Haah… Rarity, stop, I’m gonna cum… Please…” She released his cock with a spray of saliva, panting and grinning in equal measure.

“Can you get it back up if you cum?” She gasped, pursing her lips to kiss his twitching head.

“Yes he can. He can and he will.” Sweetie Belle quipped, her hoof now firmly grinding against herself.

“Y-yeah…”

“Then cum in my mouth, Spike.”

“Bad idea, Rarity.” Sweetie Belle groaned.

“I don’t care. Do it.” She pushed him back inside, her head moving just as fast as it had when she pulled away. Spike grunted as she pushed him deeper than ever, her lips striving to wrap around the very base of his cock. She couldn’t quite reach it, but he would have given her an A for effort…

“Rarity, seriously,” He grunted. “It’s gonna burn if you swallow…”

“Hmm?” She paused and glanced up at him, her lips pursed about two thirds down his length.

“When I cum… It’s hot.” He panted, flexing to try and fight back the tide. “Like… Swallowing scalding water… It cools quick enough on your coat, but… Not inside. Sweetie learned that the hard way… Remember the week she couldn’t talk or sing…?” Rarity’s expression was drawn with concentration, but suddenly grew panicked. She pulled back, releasing him once more.

“Gah! Then do it outside!”

“On her face.” Sweetie Belle grunted. Spike couldn’t hold back. He flexed twice more, his member jumping as the pleasure suddenly erupted. Gasping and twitching, Spike shot seven thick strands of creamy cum onto Rarity’s face and mane, the white ropes of release steaming slightly. Rarity gasped at the initial impact, shuddering from the pain of the heat… But mere seconds after it left his cock, it cooled enough to just be warm. Rarity sagged slightly under the assault, her open mouth panting as she licked at one strand of cum.

“Hmm… It doesn’t taste bad… Like a pepper…” She groaned. “Spicy… I like it…” She looked incredible. The way Spike’s cum landed in thick ropes across her face, painted in her mane, it was so arousing… She leaned forward and kept licking at him, her tongue spreading saliva and her own hot breath over the expanse of pink, pulsing skin. Spike felt blood leave the area nevertheless, though he knew he’d be back soon.

“My turn.” He teased. Rarity squeaked as he picked her up smoothly, his claws closing around her slender flanks. She was unceremoniously lifted onto her bed, dropped on her back, her cum-flecked mane splayed out underneath her.

“Assertive. Give it to her, big guy.” Sweetie Belle groaned, adjusting so she could watch. Spike spread Rarity’s creamy-white thighs smoothly, leaning in to sniff at her marehood. Her arousal was already apparent, but thin… She must have bathed before they arrived. She was clean, wet, and ready. Her lips were flared, glistening with arousal, just begging to be tasted… Spike couldn’t resist. He dove in, his long, forked tongue immediately spreading Rarity apart, pushing deep inside of her… The benefit of making love to a dragon… Cunnilingus was unlike anything else. Rarity gasped as Spike slid deep inside of her, his muscular appendage pressing to parts of her that were very seldom touched, if at all. She gasped out loud, whimpering as he pushed all the way in… As deep as her cervix.

“S-spike!” She gasped, arching up. “T-too much! I’m going to- AHN!” Hips arching up from the bed, Rarity let loose her first orgasm, shuddering and panting as she came. Spike pulled his tongue out, savoring the taste of her juices. She was a slobbering mess, dripping saliva and release equally.

“First time’s rough, huhn?” Sweetie Belle teased. “We measured his tongue one time… Two and a half feet. He can hit any spot inside of you…” She leaned in over the edge of the bed, her lips close to Rarity’s ear. “Any. Little. Spot.”

“F… Fuck me…” Rarity panted, her stomach twitching as she lay on the bed.

“He’ll get around to that. Trust me.” Sweetie Belle teased. “Just… Try it one more time?”

“Oh, darling.” Rarity finally recovered, smiling as she sat up. “I can cum a dozen times before I’m finished… I think one or two more from Spike’s tongue isn’t going to slow me down.” She lay back down, gazing up at Spike with that same sultry, lusty expression…

“Do it, hon… Show her what she’s missing.” Sweetie Belle abandoned the chair, and instead dragged herself onto the massive bed. There was plenty of room for her to stretch out, her legs splayed wide to display her glistening marehood, even while Spike dove in on Rarity once again.

“AAHN!” Rarity cried out immediately as Spike pushed into her, doubling his tongue back up on itself to press against her g-spot. She lifted her hips, twisting his tongue around even more, adding to the sensation… Spike felt his arousal grow once more, telling him that soon enough, he was going to be hard again. One more orgasm from Rarity and he’d be ready. “SPIKE!” Rarity cried. He was twisting his tongue about inside of her, bending it in three or four different places. Being licked by Spike was a unique, and admittedly intense experience. Rarity’s hips bucked as she rode his tongue, panting and gasping all the while. “Spike, I’m cumm-mm-mmING! AUGH!”

“Me too! Harder, Spike! Make her cum!”

“Hnng!”

Sweetie Belle and Rarity came simultaneously, and both of them squirted. Sweetie Belle’s release spattered directly onto Rarity’s chest, even while Spike hungrily drank every drop from Rarity’s pulsing cunt. Panting heavily, Rarity rolled her head to the side, scowling at her little sister.

“Did you… Just cum on me…?” She whimpered, shuddering as Spike withdrew his tongue from inside of her.

“C-couldn’t… Ngh… Hold back…” Sweetie Belle moaned, twitching as she lifted her head to smile down at Rarity. “’Sides… No holding back, right?”

“Yes, but… With Spike, not with my sister!” She rolled up onto her side, glaring down at Sweetie Belle angrily. “I’ve half a mind to kick you out right now!”

“Oh, relax, Rarity…” Sweetie Belle groaned, letting her head fall back to the sheets. “You act like it’s the first time you’ve EVER been around another mare when she came.”

“Exc-USE me!” Rarity flustered. “I’ve NEVER entertained another m-“

“Berry Punch. Applejack. That one pegasus with Photo Finish.”

“Wh- What, I… I thought you were out?!”

“Came home for one reason or another… And then promptly left.” Sweetie Belle teased. “Face it, sis. You’re bi.”

“Sh… Shut up…” Rarity mumbled, suddenly sagging. She appeared defeated, but only for a moment. Her eyes flashed dangerously as she glared down at Sweetie Belle. “Well fine, then. Since you’re so keen on cumming on your sister, you can clean it up.”

“What are you- MFF!” Rarity smoothly straddled Sweetie Belle, driving her stomach downwards until the soft, silky-smooth hairs of her coat were forced into her sister’s mouth. Sweetie Belle tensed for a moment, her muffled words unintelligible. But she readily acquiesced, and judging by the way Rarity groaned, with much more vigor than usual. Spike's arousal slowly rose up, making him groan as the first tendrils of pleasure wafted through him. The memory of Rarity's recent blowjob and the lingering taste on his tongue were enough to draw the dragon up onto the bed along with the two mares. Rarity glanced back as she felt the depression in the bed, and upon seeing Spike slowly crawling towards them with an exposed, throbbing member, smiled.

"Hmm... You're ready again?" She teased, swaying her hips. Her glistening lips were still flared, and as Spike watched, she dripped arousal onto Sweetie Belle's coat. His wife groaned into Rarity's coat, squirming her hips. The way her hooves were pinned, she was unable to do a thing to please herself, or ease the ache that was undeniably pulsing through her core. Spike leaned in, knowing he had an entire night to enjoy either of them. Slowly, his tongue slid into his own wife, groaning at the familiar taste and feel. She was not unlike her sister, surprisingly enough. Rarity was perhaps a little bit larger on the inside, being the more well-grown pony, but still every bit as wet and warm...

"Ooh!" Rarity jumped a moment. "She bit me... Haahh..." Spike smiled and slid his long, serpentine tongue deeper, touching all the spots inside Sweetie Belle he knew so well by now. "Aah! Ow!" He pulsed his tongue in and out, then around in a circle. This time, Rarity's shuddering breath made his dick throb. "Haah!" She gasped again, rising up on all four hooves. "E-enough, Sweetie Belle... If you're going to bite that hard, then- eep!"

"Give it to 'er." Sweetie Belle panted underneath her sister. Spike had smoothly transitioned, his tongue slipping inside of Rarity next. The elder sister groaned as Spike teased her, not keen on making her cum. He easily could have, but he just wanted to put the brakes on her assertiveness. He was in charge of this little session. Sweetie Belle knew it. He knew it. No one was going to stop him. Groaning softly, he pushed his tongue in and out for a few, making sure to give Rarity's tight pucker a few saliva-coated licks.

"Hmm! N-not there, S-spike!" She panted. "I can... I can handle your average stallion back th-there, but... N-not you..." She panted, shuddering underneath him. Spike's claws lowered to Sweetie Belle's dripping core, sliding one of the smooth, hard tips inside of her. She gasped and flexed in return. Spike was pleasuring two mares now, his sister-in-law and his wife. His throbbing member demanded attention, so his free claw fell to idly stroke the massive shaft, groaning into Rarity's core as he scratched the itch, so to speak.

"Give it to her, Spike." Sweetie Belle panted. Spike was in charge, but he followed Sweetie Belle's instructions. Especially when they were so close to his own desire. Rarity gulped audibly as Spike pulled her backwards, his tongue leaving her dripping marehood with a spray of saliva.

"Hmm... Are you ready, Rarity?" He teased, pulling her back until she was spread out against his head. She gave a soft nod, her teeth clenched firmly. Slowly, he pushed his hips forward, spreading her tight, dripping center apart. She gasped, inhaling deeply as he moved in...

"S-spike..." Rarity panted, her entire body tense beneath him. He moved his claws up and down her sides, massaging the tense unicorn, relieving some of the stress.

"Takes time to get used to... The first time with Spike, I felt like I was going to die..." Sweetie Belle moaned. Her hooves slowly raised, massaging Rarity's shoulders, helping to keep her relaxed. "Relax. Let him do the work. Just take it in, sis..."

"Haah... Okay..." Slowly, like inching into a hot bath, Rarity relaxed... Spike took each inch he could get, moving in until he felt like she could handle no more. Which was actually quite a bit. He still had almost half of his length to go. Not that Sweetie Belle was much better. He groaned and slid out half of what he had put in, giving Rarity's hips a squeeze before sliding back in. "Ahn! Spike!" Rarity gasped, her body shaking. She threw her mane back, letting loose a hot breath at the same time.

"That's the way... Take it, Rarity. Take it all." Sweetie Belle urged, rubbing and massaging. Spike watched one of her hooves slide back down inbetween her legs, tending the aching need left behind by Spike's long tongue. "Haah... All of it... Spike, please, make her cum."

"C-can't..." Spike grunted. "Sh-she's so tight... I think I'm gonna cum soon."

"UGH!" Rarity collapsed at that moment, the sudden movement slipping Spike out as she collapsed on top of Sweetie Belle. "Haah... Haah..." Her heavy panting washed over Sweetie Belle's stomach, and looking down, Spike could see her wet hole oozing more clear liquid. She had came again.

"Fuck... How close are you, Spike?" Sweetie Belle asked, pinned beneath Rarity.

"Real close." He panted. He was scared to even touch it. The way he was oozing pre cum, he could easily have cum any second.

"Do it. All over her back." Sweetie Belle still ground her hoof, despite the way her foreleg was pinned. Spike moaned as his claw wrapped around his twitching member, sending him beyond the point of no return. He knew, with as pent-up and fatigued as he was already, this would be his last.

"Haah... Babe, I'm gonna cum..." He groaned one last warning. Right as Rarity looked back at him, the first thick rope of cum shot out, catching her on the cheek. She barely even flinched, but instead just panted and groaned for each new strand that landed on her. Sweetie Belle caught the fallout, saving the sheets. Spike painted both of them with a huge load, his testicles emptying themselves on the two white mares beneath him. When all was said and done, he released his cock, moaning in the aftermath of post-orgasmic bliss.

"M-my..." Rarity moaned. "It's awfully warm..." She wiped at the strand on her cheek. "And sticky... Hmm..." She licked herself clean, moaning as she laid her head down. She appeared to not even care that she had Sweetie Belle pinned beneath her. Sweetie Belle didn't mind, it seemed... She slowly closed her eyes, her breathing slowing down.

"Are we... Staying the night, then...?" Spike moaned, his claw shaking as he sagged slightly.

"If... If you want..." Rarity's eyes closed, her form curling up atop Sweetie Belle a little. Spike stretched out next to them both, draping an arm over the prone mares. With a heavy breath, he closed his eyes, feeling completely tapped.

And, for one reason or another, very happy.

----------- Notes from the Author -----------

Sorry, folks... I know I could have done so much more with this. It's past my bedtime, and I'm still kind of recovering from the long weekend. More requests to come, since they're pretty much the only thing I have to write over the weekend.

Blog post sometime tomorrow explaining more.
