Chapter 1

It was a quite quiet evening in the boutique for once, well for once when Sweetie Belle was over to visit. If the younger mare wasn't trying out a new song for her older sister for approval, she was still retaining her rather hyperactive side, happily bouncing about and more often than not trying to help Rarity and ending up getting in the way. But at least Rarity would admit, she took to cooking a bit better with lessons and didn't liquify, then burn the toast.

The sounds of the outside night were the most noteworthy things that could be heard, a few crickets and the occasional creak of the furnishings as the heat of the day wore off. Then suddenly there was another sound that added itself to the gentile night sounds. Something that sounded much like a very quiet little whimper. At first it was just the one sound, but after a few seconds, there was another and another, almost a muffled cooing like someone was trying their best to keep quiet.

The noises continued, but still in their muffled state, the source of them seeming to be up the stairs and down the hall. It wasn't Rarity's room at all that they were coming from, though that would have likely been the most reasonable assumption. No, they were coming all the way from down the hall, through, or more accurately, under the closed guest room door.

Inside, the reason for the noise was rather clear, even a peep through the keyhole would have told the whole tale. The little songstress was completely in the nude, one hand playing with her pert breasts and the other one teasing at what was already an incredible length of dusky equine meat. "Mnnnf... Oh..." She was doing her best to keep herself quiet, each time that she whined out her pleasure, Sweetie fought back the tendency of her excited tone to squeak.

"Ah... Nf..." Her slender little fingers danced up and down her length at an increasing pace as it rapidly grew under her affections, her young heart pounding as she watched herself becoming increasingly more erect. In more ways than one, Sweetie Belle was much like her elder sister it would seem, the coloring, the affinity for having a lovely singing voice and just as notably, for being exceptionally well endowed between the legs.

"Oooh... I... I suppose..." For the young mare it seemed like a very good idea as she looked at her swollen cock, the head of it throbbing more than eye level. Her mouth opened up and soft lips pressed into the flare, sucking gently against it, letting it drool into her mouth and around against her lips, bits of the slick precum welling up quickly to drizzle down over the dark tip and glisten in the dimmed light. "Oh..." Sweetie also shared the affinity her elder sister had for a lovely, if muted flavor it seemed if the way that her tongue was greedily licking her tip as if it were ice cream was to be trusted.

"Mmmph..." As her lips wrapped around the head, it helped to further muffle the sounds in the room, bringing them down to such a degree that one would have to be pressing their ear to the door in order to hear anything at all anymore. For a time, the silence reigned again other than the gentile friction noise of Sweetie's hand massaging her length and the equally quiet sucking of Sweetie's lips working up and down, pushing herself almost into the back of her throat and then pulling back towards the front of her mouth. It was only a small segment of the entirety, but it just felt oh so good for the little mare, far too good for her to stop.

For several minutes, Sweetie kept up this pace, suddenly going a bit wide eyed as cock stiffened up a touch and warm precum burst from the tip in a rush. One more attribute that Sweetie shared with elder sister, productivity. Her cheeks bulged with the unexpected volume and with a noteworthy *splrtch* it spewed from the corners of her mouth, forcing the songstress to recoil, her mouth hanging open and spilling that entire mouthful back down her cock as she coughed sharply, ejecting some of what had forcefully deposited itself down her throat.

Even as she cleared her throat of the unexpected gob of pre-spunk, the young unicorn didn't stop stroking herself, that stroking hand only sped up in fact, working along a considerable bit of her length, roughly from her medial ring to her tip, eagerly. As she grew closer to the inevitable peak of her pleasure, Sweetie found herself leaning back, allowing her to more easily work her erection.

The whimpering sounds of bliss started to escape from her mouth even more as her release built towards a head. "O-Oh... Oh... A-Aah... AAAAAH!" It was only a brief lapse of control, before she reined her voice back down, but it came with good reason. A thick stream of white burst from her shaft, the ivory hue contrasting sharply with her more dusky dark member. Higher and higher stretched the long streamer of creamy spunk, reaching it's apex and then curling back down as gravity finally caught up, sending the deluge pattering noisily to the floor.

While not on par with the same absurd level of production that Rarity was capable of, Sweetie Belle did share the general copious nature of her elder sister's climaxes, again and again firing off torrents of spunk that splashed to the wooden floor around her, filling the room with a sound not unlike a steady rainfall. Every couple of strokes she produced such an impressive display, progressively painting a milky puddle around herself that spread out from the mare milking herself in the center of it. There just seemed to be more in the hung little pony's body than it should have been able to hold, yet she was intent on draining herself and sating that ache in her balls that had started her down this road in the first place.

After about a minute and a half of constant little mewls of pleasure and nonstop spraying her spunk around like the little hose that she was, Sweetie finally slowed to a stop, her chest heaving and little gasps of relief puffing out. Only after she had a handful of seconds to come down did she realize what a mess she had made. Cum clung to her body in a few places, some of her mane and tail getting sticky, but that paled in comparison to the disaster that she had left on the floor. Ropes of semen crossed over and back along themselves, joining with each other in many squiggles and pools both in front of her and behind her for roughly seven feet in each direction.

"Uh... Oh..." The room itself reeked of sex as well and even the unicorn could smell it. She was going to have a lot of cleaning up to do before...

Suddenly there was another sound, one that there hadn't been all night, the soft click of a key in a lock. "Sweetie Belle are you alright? I heard..." The moment that the door opened, the voice cut off sharply. Perhaps it had been the single orgasmic cry, perhaps the noise of semen splashing about, but it had been sufficient to wake Rarity; who now was surveying a little mare sitting in the middle of a small flood of semen with her dark cock still twitching and drooling remnants of it's orgasm down it's length without a care in the world.

"SWEETIE BELLE!"

Chapter 2

"SWEETIE BELLE!"

Sweetie could not have squeaked any louder the moment that she heard that voice. Her entire body sprung backwards almost two full feet in surprise, sending her backside and her hooves slipping into the sticky mess that had splashed about her. This was the last thing that she had wanted! She didn't want her sister to see what she was doing, to glean it from the mess that she had left, but here she was, caught right in the act with her dusky massive shaft still unrepentantly leaking semen.

"R-Rarity! I...I...I...." Sweetie's eyes were wide with stunned shock, like a cornered little animal that wanted nothing more than to find the nearest hole and run away. Indeed, had Rarity not been blocking the door the younger mare would have probably gone and locked herself in the bathroom and stayed in there for the better part of a day out of pure shame.

"I... I'm sorry about the mess! R-Really! Really I am!" Sweetie tried to backpedal a little further, but her slicked up hands and hooves were not finding much purchase and it was making her look rather silly with the frantic way that she kept subconsciously trying to get them under her again. "I'll... I'll clean it all up! I promise! I'll wash the bedding! I'll make you breakfast in bed tomorrow! Just please, please PLEASE don't be angry, please don't tell mom and dad about this!"

Rarity certainly looked like she wanted to punish her little sister for all of that mess she had made. It was one thing to get a little semen here and there, but the more that she looked around the more that she saw the extent of Sweetie's need for release. Spunk wasn't just on the floor and the bedding, it was on one of the walls, an end table and even the ceiling in a few places where the eager young unicorn had unloaded more feverishly than the rest. The elder mare's arms crossed across her chest as she looked down her nose at the little mare who couldn't try to apologize enough for what she'd done.

"I'm sorry Rarity, I'm sorry, I'm sorry, I'm sorry!" Sweetie Belle really sounded like a broken record, but it was all that her frantic mind could come up with at the time. Her big sister wasn't talking to her, just staring at her and, Sweetie knew, she had to be silently judging her as well. The two already had their little spats when Sweetie tried to help and made a mess, but this wasn't helping anything, this had been Sweetie helping herself and she knew it, there was no explaining this away!

"Sweetie Belle!" There was the voice again, it wasn't as surprised, but it was every bit as commanding as her sister could be and it made the young mare freeze in place. This was it then, here it came, she was going to find out what her punishment was going to be and it wasn't going to be good either. Sweetie's ears pinned back against her head and she looked up at her big sister rather sorrowfully, her body language just screaming that she was waiting to reel backwards in horror.

Rarity drew a deep breath and sighed, letting her arms fall to her sides before she brought one of her hands up to her face and rubbed the spot between her eyes between thumb and forefinger a few times. "Sweetie Belle darling. Whatever am I going to do with you?"

"U-Um... W-Well..." Sweetie didn't have an answer for that, it was no different than asking a child who had done something wrong what their punishment should be. They didn't want to be too harsh on themselves, but at the same time, they couldn't bring themselves to develop the gall to say 'let me go scott free'.

Rarity sighed again and let her hand fall from her face. "I suppose I should have known that this would happen sooner or later. It's not as if you're not my little sister and it's not as if I didn't do much the same thing when I was younger either." Those words were muttered softly, mostly to herself, but still loud enough that Sweetie could hear them as well.

"R-Rarity?" Sweetie was about at the point where the lack of any outcry further from her neat and tidy sister was making her nervous, the last time that Rarity had tried to keep all her frustration with her in, she had blown up and the last thing that the young mare wanted was to have her sister renounce her as a little sister again!

"Hush Sweetie darling." Rarity closed her eyes and actually smiled a tiny bit at the young mare, extending a finger and stepping forwards, not even caring that she had put a hoof into the puddle of Sweetie spunk. The finger pressed into the younger pony's lips and stayed there as a notice of intent that Rarity didn't want Sweetie piping up any more for at least a while.

"I've known for a long time that you had that thing you know, did you really think that I'd forgotten from all those times that we bathed together when you were younger? Big sister has a very good memory. I just wish that you had told me that you were starting to get this pent up." She glances around the room once more. "You're both a very big and an exceedingly productive little mare just like your sister, I would have understood if you'd said something you know."

Sweetie wasn't in a state of flux as her sister spoke, was she not going to be punished for this? Was Rarity working up to that? Was this going to be one of those dreaded 'I'm so disappointed in you' speeches that she had gotten a few times when she brought back a poor report card as a filly? She opened her mouth up like she was going to speak only to have that finger push down more firmly than ever.

"Consider this your warning Sweetie darling, from now on when you're staying with sister and you need to get yourself off, you come tell me and I'll see to it that you can do so in a place a little more appropriate."

Sweetie's eyes turned up towards Rarity, was that it? She wasn't going to be scolded, she wasn't going to be sent home? Mother and father weren't going to be told what she had been doing?!

Rarity cleared her throat softly and then broke into something of a more genuine smile. "Now then darling, let's get you a bit more adequately taken care of so that we don't have to worry about this happening again anytime soon hm?"

"W-What? What do you mean sister?" Sweetie couldn't believe that her big sister could possibly mean what she thought that she did.

"Darling, you were still rock hard that whole time!" Rarity pokes a finger into the younger mare's towering shaft only to have it spring right back into place as soon as the finger was removed. "Clearly your body is thinking something very different than your mind if you didn't even realize that your erection didn't go away despite your orgasm or your surprise."

Sweetie's cheeks turned the brightest shade of red upon hearing that, even moreso than she had been a few scant minutes ago when Rarity walked in on her. It was as if every bit of blood that hadn't pooled in her oversized cock had rushed into her cheeks "I... I... Well... Um... I suppose..."

"That's what I thought darling..." Rarity glanced over and levitated a chair from the corner of the room over and set it down right next to herself. She stripped her robe off and levitated that into the closet right near the corner where that chair had come from. "Come here darling, let's get you taken care of."

Sweetie couldn't believe what she was hearing or for that matter what she was seeing. Her big sister was a pretty mare and one that she very much hoped that she would grow up to be like and Rarity was presenting herself so freely like this... For her?! "But... But Rarity... The mess..." She whimpered softly while slipping herself up into her big sister's lap. Along the way her backside bumped into the meaty swell of her elder sister's pristine white sheath, scooting back until she was resting her body against Rarity's stomach, legs splayed out so as not to kick her sister's testicles. Sweetie couldn't help but stare down for a moment. She was a big mare by all rights, but goodness did Rarity have huge balls! Sweetie actually found her mind trying to fathom just how much that Rarity would cum by comparison!

"Sweetie darling, the room is already a mess, we'll have to clean it up no matter what. No sense in cleaning it up if there's a chance that you'll just make the very same mess all over again is there?"

Sweetie Belle's gaze turned up towards Rarity as her little plot found itself rubbing against Rarity's lap without even realizing that she was starting to get her sexual side running once again. "But..."

"Why do you think that I'm joining you Sweetie darling? If I'm going to clean a mess like this up no matter what, I would rather know that I had some fun helping make it~" She chuckles and nuzzles down at Sweetie Belle playfully.

Even though Rarity had not been the one with the oppressive need to get herself off, it didn't stop her heavy alabaster shaft from slowly sliding itself out between her legs and also between Sweetie's either, the ivory thickness nudging into Sweetie's ashen balls and nudging them up and out of the way.

Sweetie began working even more in earnest while watching Rarity growing more and more aroused herself. One of the younger mare's hands finding its way against her dark shaft to stroke along the side with as much as her slender digits could get around being encompassed. Her hips shifted and lifted just a touch, allowing her to drag her thick, spunk stuffed testicles along Rarity's growing erection, providing both herself and her sister a considerable amount more pleasure than had she just sat there.

"Ooooh, now that does feel divine Sweetie darling~" Rarity's voice betrayed her surprise, but also her pleasure at how her little sister had been creative enough to work them both over in her own way. The reward for such creativity from Sweetie was one of her sister's hands pressing into the side of a dark orb and rubbing around in tiny circles that expanded into larger ones the more that Rarity rubbed.

Precum began dripping from Sweetie's needy maredick right onto Rarity's after a few minutes of that, but it didn't have far to drip either. For as rigid as Sweetie had been to start with, Rarity had grown to be as such during the course of their sisterly tryst. A massive white shaft towered up from under the ebon one, pressing into it for a considerable distance before Sweetie's lack of a body pressing down and angling her a different way made them separate.

"Wow..." The little mare had taken a while to realize that the firmness that was nudging into her cock's underbelly was indeed Rarity's own penis, having been so obsessed with her own that she sort of spaced it out. She couldn't keep from tilting her head to the side and gawking for a little while. As big as she was, even Sweetie was surprised with just how huge that Rarity was.

Rarity gave a knowing smile to her little sister, not the first time, not the last time that she would be stared at for her endowment. "Go on darling, grind yourself into big sister, it feels good for me too you know."

Sweetie's head bobbed up and down with eager nods, sliding herself all over Rarity's lap in an effort to saw one massive she-dick into another one as quickly and as fully as she could. Little squeaks and coos of pleasure just couldn't stop falling from Sweetie's lips the closer her fevered ministrations got her to a second climax.

"Gently darling, gently, there's no rush~" Rarity purred, as she pulled her little sister back to the furthest part of her lap, pressing Sweetie's backside against her midriff and rocking her hips in a slow, deliberate way, sliding much of herself against Sweetie Belle with an ease that belied practice.

Sweetie squirmed with pleasure, but trusted her big sister enough to not tamper with what Rarity was doing. The little mare nuzzling and kissing eagerly up at her sister with growing frequency. It was all that she could do to work off the tension that was building and threatening to make her lose her mind.

"R-Rarity... I... I'm going to cum..." Her voice squeaked in a panic, trying to hold still even though her dusky mare meat was bucking, just begging to be pushed over the edge.

Rarity knew why her sister was hesitating, Sweetie wanted to make sure that her big sister not only wasn't going to scold her for what was to come, but also she wanted to be sure Rarity was satisfied too. "It's okay Sweetie darling." Rarity's voice was comforting and warm. "Big sister wants you to cum for her~"

Rarity's lips met with Sweetie's and held for a prolonged period as she pulled her hips back and held her little sister in place in her lap as best she could. Those same hips made a trip forwards a half second later and that was the extent of what Sweetie's still pent up self could take.

"Mnnnnnnn!" A high pitched nasally whine poured into a kiss that she really didn't want to break even though her hips snapped upwards in a release of tension. For the second time that night a thick gush of white burst from the young unicorn's cock, splashing it's rich sticky volume across the floor in waves. Only this time, for some reason it felt so much better, so much more fulfilling as her full balls sent their contents skyward with increasing velocity each time. Sweetie now knowing that she wasn't just satisfying herself, but she was showing off for her big sister. A big sister who had not only allowed her to do this, but had requested it!

Chapter 3

Sweetie Belle spent a good deal of time in her big sister's lap writhing lightly, panting and cooing in bliss as her hips kept coming up again and again into her needful orgasms. The sound of the soft patter of thick ropes of the young unicorn's cum splashing along the floor mingling with her cute little mewls of pleasure. Even in a state such as this when she could have screamed with enjoyment, for some reason, Sweetie seemed to prefer to sound a little more cute, perhaps just because that worked well with her big sister's perception of her.

After a time though, her thrusting hips started to slow and the squeaks and mewls of pleasure started to die down and turn into little rumbles of post orgasmic bliss, broken only by the panting of her slightly less experienced body as it took some time to cope with the strain and recover. Little white backside slid back a little further, pressing into her sister's stomach a touch more flush than ever as she relaxed and her body sagged a tiny bit from the release of tension that had wound her so tightly.

As her body began to sag, so too did that rather sizable ashen shaft of hers droop a little bit before catching on something that wasn't letting it sag any further than a few inches. Lidded jade eyes gazed up and outwards to see what was happening, only to realize that she was resting her own member on her elder sister's. An elder sister that was still quite rigid and judging from the soft drool of milky precum from her tip that dribbled to the ground with the patter of a leaking faucet, had not cum herself yet.

Rarity was paying little mind to any of that at all, simply caressing her little sister's mane as she caught her breath, bringing her hand down from top of head along the side of it affectionately. "Feel better now Sweetie darling? That was quite a lot that you had in there you know, you really should take better care of yourself to not end up like that!" Rarity was hardly one to talk, she had a worse habit of denying her own sexuality in the name of getting something done for a deadline or cramming an extra project into her schedule for a friend. Little wonder that she needed so much time at the spa to help her unwind some weeks!

"Uh uh..." Sweetie nodded her head and pushed herself into more of an upright seated position, not wanting to slouch and end up having her elder sister support her so fully as she had been. "But..." She glanced back at Rarity for a moment, then forwards at the two fat pieces of equine flesh. "But don't you need to cum too big sister? I'd feel really bad if I was the only one..."

"Oh I'm fine Sweetie darling, I told you not to worry about me!" Rarity was quick to flip a hand in dismissal even though she was sporting the sort of wood at the moment that looked like she hadn't gotten off in the better part of a week. "I was more worried about you taking care of yourself than anything so that you don't end up having to make a mess like this again and think that you had to hide it from me! I'll just take a bath after I clean up a bit and it'll go back to normal~" She didn't sound overly convincing, but since when didn't a sister make a sacrifice for a little sister from time to time?

Sweetie wasn't quite as naive as most might have thought her to be, innocent in many ways and maybe a little airheaded from time to time when it came to using common sense, but she picked up enough from her elder sister to know that Rarity was being facetious with her. "Rarity..." She leaned forwards to pet at the fat ivory spire and rub it a couple of times with her small hand. It really put into perspective just how large that her elder sister was when she tried to get a good grip on it with her digits and she couldn't get her hand even halfway around the straining girth.

Not that said straining girth made things easier for the delicate hand to caress it. Rarity's mouth said one thing, her body another when Sweetie stroked along her, because it just took that tiny bit of friction and love from the younger mare to make her elder sister's shaft buck sharply and tear itself free of the probing fingers, slapping sharply into the semi-hard charcoal colored member that was resting atop it and making it flop upwards and then slap downwards against Rarity's cock, hanging in the slightest of curves downwards against the far side of the large white tool.

Sweetie glanced up at her big sister again and shook her head, leave it to Rarity to be the stubborn one. Maybe she didn't think that it was proper to do a thing like this with her little sister? Sweetie knew all about her big sister resisting things and finding ways out of them because they didn't line up with some silly preconceived notion of what a lady should act like, though at the same time Sweetie was a lot more liberal with her thoughts and feelings than a lot of ponies too. Sweetie Belle wasn't buying it and she wasn't going to let her big sister get away with being the only one that was generous with her. It might have been a sense of sisterly duty, maybe instead it was just her desire to thank Rarity for what she'd done, or even perhaps it was just to prove her big sister wrong, but Sweetie wasn't going to let Rarity leave with that hardon unattended.

The little mare slipped from her sister's lap with a twist of her hips, the young pony ignoring the fact that her hooves had spattered into the spilled cum against the floor, making the walking somewhat treacherous. Small digits wrapped around as much of the alabaster length that they could, gripping the thinnest portion of it just under the flare as she tugged it towards her body. "Come on Rarity, that's not fair and you know it, you were a good big sister to me and you... Well I thought you were going to ground me and make me clean all this mess up by myself, but instead you made me feel so good. Can I please make you at least feel good too? Just for a little while?" If there was one thing that Sweetie was good at in life it was giving her big sister puppy eyes and she had them going the whole time she was trying to convince her sister.

"Mnf, Sweetie darling really now..." Rarity did her best to give one more weak little protest, but Sweetie was having none of it anymore. The final protest was all that it took for Sweetie to tug firmly enough upon her sister's cock to make Rarity have to twist and stand out of the chair to avoid some discomfort. Leave it to the little mare to be blunt and not know that there were just some things that should not be done in the name of proper refinement! Rarity huffed softly to herself and gave in at last. "Very well Sweetie Belle, very well..."

The giggling that came from the younger mare as she got her way was nigh musical and while it shouldn't have been possible for a little pony sporting such a sizable droopy length to skip with any degree of reliability, that was just what Sweetie did, closing a few steps to her bed and then hopping upon it, letting Rarity herself join and seat herself.

Sweetie was not often forward with Rarity, but this was one of the times that she had convinced herself that if she didn't drag her big sister along by the hand that Rarity would keep on lagging behind her. She half shoved her big sister down onto the bed, which was met with a soft squeak of surprise and indignation, but little more than that since the mattress was right there to catch her and was, like Rarity's own bed, soft as could be, not likely to cause even the briefest flash of discomfort.

"Mmm, you're so pretty like that big sister~" Sweetie cooed with a gentile bounce against the mattress, observing her sister laying in a swirl of silken sheets and well kept purple hair. Her big sister was just so pretty, Sweetie was jealous in a lot of ways, not of her stuffiness, but certainly of her talents, how she was well spoken, her looks, her curves and her endowments; although Sweetie Belle shared at least the lower one with Rarity.

The younger sister couldn't afford to wait too long with her admiring, much as Rarity enjoyed it, her sister might have second thoughts if she didn't do something quickly to keep that from happening! So once more the young shemare was on the offensive. "And you're so big too~!" She giggled and stroked the top foot or so of her elder sister's shaft while angling herself down and her sister's meat upwards towards her lips, giving it a tentative kiss and then a lick to see just what her big sister tasted like what with all of that leaking precum that had not stopped flowing during the whole of their back and forth.

"Mmmnmuah!" She closed her mouth around a sizable quantity of the stuff and pulled her lips away with a kiss, holding the stuff in and letting the flavor wrap around her tongue for a while. Sweetie wasn't the most experienced mare, but she was plenty large enough to suck herself off and that practice at least was enough to help her work on her big sister with a degree of expertise.

Rarity flushed a tiny bit across her cheeks seeing her little sister acting... Well she couldn't decide if it was sultry or if it was slutty, but it was adorable and it made her much more disinclined from wanting to leave than she had been a few minutes earlier. It didn't get any easier for her to resist either since Sweetie only had pulled away long enough to swallow and then had her lips wrapped back around that shaft again just seconds later. "Nf, Sweetie darling, be careful at least!"

Being careful seemed to be the last thing that was on Sweetie's mind right now, no matter how ungodly thick that her elder sister's shaft was, she was going to pleasure it and that meant getting it into her mouth! It took some doing, but if there was one thing that Sweetie had as a trait other than being adorable, it was that she was persistent, she didn't give up on things easily. That persistence was put to the test as she wiggled her mouth back and forth, leaning in with as much force as she could put into that rock hard erection, letting the spongy tip spread her lips wider and wider with the passage of time.

"Mglumpfh!" Lubrication was not a problem and once she got it started and past a certain point, Sweetie was surprised with how fast that her bigger sister actually popped inside of her mouth! It was sudden enough to make her startle and cause the pressure that she was exerting downwards to stop for a brief moment while she made a muffled little squeak from cheeks now bulged out a bit with a bountiful mouthful of horsecock.

Rarity almost worried that she might choke her little sister, but the worry melted away when the startled sound melted into a gentile rumble and a lidded gaze back up from Sweetie. Even the young mare's lower half was perking back up, twitching after it's little break from the second orgasm of the night and poking into Rarity's body as it throbbed itself back to an erection that nuzzled itself between shoulder and the side of the older pony's head. Of course Rarity should have suspected that given her own size that Sweetie had blown herself plenty, but what big sister with the same refined way of thinking as Rarity would ever naturally assume anything like that of their adorable little sibling?

Sweetie's head started to bob, gently at first, then a touch more swiftly as she got more of a feel for the increased thickness in her mouth. It was an acclimation process to be certain, but she had enough practice that she was able to get herself into a steady flow of motion much faster than the average pony would have. Her goal went far beyond just sucking on a little bit of her big sister though, Sweetie wanted to make her elder sister feel so good that she was not going to help but want to explode, and to Sweetie Belle, that meant finding a way to deep throat that excessive length a fair distance!

Rarity watched the whole thing with wide, adoring eyes as Sweetie worked on her. She had been hesitant to desire anything like this from her sibling, but at this juncture, she was questioning herself as to why she would have ever not wanted to let her little sister do this! It felt exquisite even though it lacked a little polish, the heat of a tight mouth and even touches here and there of the back of Sweetie's throat squeezing down on her were making it harder and harder for Rarity to not start pushing her hips forwards in time with the bobbing and sucking. Thankfully for her, at least she kept enough of her wits about her to remember that doing so would likely gag the young mare by giving her too much too fast. 'Let her work at her own pace, yes, just like that Rarity, just enjoy it'.

Sweetie's excited little body was getting squirmy again as she worked, she kept stealing little glances up at her sister from time to time to make sure that she was doing well and every time that she did, she wasn't disappointed to see a degree of pleasure growing across Rarity's face. Her curled two-toned tail was swishing of it's own accord behind her, softly rustling against the sheets while her mane dragged along it a little more noisily because of the proximity. Knowing that she was making her elder sister feel the same pleasure that she herself had been moments earlier really made Sweetie practically glow.

"Mnf... I-I suppose darling... That I should at least reciprocate." Rarity had been aware of her little sister's tip nudging into her cheek for a while now, but she'd somewhat tuned it out. Horrible of her she knew, but she couldn't deny that Sweetie was quite ready for another round and Rarity couldn't bear the thought that even if she did cum for her sister, that Sweetie would be the one left wanting with an erection when she finished. No, that would never do! So with a few strokes and a gentile turning of her body while making sure that Sweetie herself moved just so, Rarity brought the tip of her sister against her lips.

Rarity was a good deal more practiced than her little sister when it came to fellatio, hers wasn't the only that she had experience with and while a lady would never openly admit to things of such a nature, Rarity strived for perfection in all things, which meant that she wanted to excel in the erotic aspects of her life as well. If you're going to grace someone with the pleasure of your body, make it an experience that they would never forget! Unlike the efforts that Sweetie Belle had to put in to get the girth of her sister inside, Rarity barely took more than a second's pause to get her mouth opened wide and the ashen flare between her lips for a firm suckling.

The sudden and unexpected pleasure of Rarity's mouth around her brought a stifled and muted squeak from the younger pony and a renewed desire to thank her sister for all of that, making her shove her head down firmly and more or less clog her throat with her sister's dick. Furthermore, she didn't exactly have the greatest degree of self control like her sister did and having a warm hole wrapped around her made Sweetie instinctively start to push her hips against it, see-sawing her body as hips went forwards one way and mouth pulled back before the two positions were reversed.

Eager little mare as she was, to say nothing of pent up little mare, Sweetie Belle was again the first one to cum between the two sisters, mewling and shivering as the desire to climax overtook her, silent resolve making her somehow remember to keep sucking upon her sister though.

Warm white cream started to spill into Rarity's mouth, spilling in tiny volumes from her lips as the first stream was a bit surprising to see so early. Ever the proper lady though, Rarity composed herself nearly instantly and she set to drinking down the offered load, cheeks pulling in slightly, as much as they could with her sister's girth still making them bow out, and throat pulsing as she swallowed down thick and sticky ejaculation upon ejaculation. Rarity handled most of it with relative ease, spilling only moderately when the volume fluctuated from time to time and Sweetie unloaded an excess amount with greater force than usual.

While that was happening up top, there was indeed some action down below to match. The feeling of her little sister spilling her need into her making something in the back of Rarity's mind tingle, the buildup of pleasure finally was getting to her and while she too could not moan for her little sister, that hardly mattered, it was time for Sweetie to return the favor and Rarity didn't fight it in the least, letting herself fall completely into the washing waves of pleasure.

Although maybe when Rarity let herself go, she should have at least tried to hold herself back a little bit. Rarity was a good deal more productive than her little sister was and even if Sweetie had been adept at drinking her own loads, which she was not nearly so much, Rarity was another matter entirely. Sweetie's mouth filled and cheeks strained out like a chipmunk in a flash as her sister unloaded. Even though she did her best to swallow down what she could, she was hopelessly outmatched compared to the productivity.

*SPLURCH!* Thick streams of semen started to spill from Sweetie's tightly stretched lips as the semen backlog in her mouth grew. Splashes of whiteness began washing back along Rarity's shaft and spilling over Sweetie's snout, cheeks and chin. No matter how much the young unicorn swallowed there always seemed to be more waiting for her to the point that at least half of her sister's output was just swirling around in her mouth before shooting right back out, escaping anywhere it could find. It didn't take long before all of that back flow began cascading over Sweetie's neck and spilling along her modest chest, pooling on the sheets between them, rippling outwards over the wrinkles in the silk fabric, just one more thing that was going to be needing a good cleaning by the end of the night.

Chapter 4

By the time that the effects from their mutual climaxes started to fade, it became quickly apparent to Rarity that she could not stay on the bed for much longer. Almost single handedly she had managed to leave herself and her sibling laying in a puddle of sticky whiteness that was seeping into the sheeting and threatening to not only stain it, but to work its way further down and into the mattress.

"Mf." She pulled her lips from the ashen shaft, carefully sliding them shut around the receding girth so as to not spill more before giving one final swallow. Her obsessive tendency towards her own appearance got the better of her at that point, obliging her to bring her fingers up to her lips and rub them around, scooping the meager bits of semen that she had been unable to sufficiently handle free and then lick them dry.

"Sweetie darling?" Rarity became vaguely aware that the sensation of sucking still hadn't stopped between her legs even though she was no longer force feeding the young unicorn with her semen as she had been. The first thing that concerned her was that she had made Sweetie's mind snap to the degree that her body was just acting all on it's own without any reason other than to maintain a steady course of action that had been working well for it over the past few minutes. Those concerns were thankfully unfounded for the elder sister. Sweetie was just enjoying herself, polishing her elder sister even more and the only swallowing she was doing was just to get the frothy slurry of leftover spooge and saliva that her tongue had whipped up out of the way so she could keep going.

Rarity could have sat there and watched that sight for hours, it was both heartwarming and erotic all at the same time, the way that the little mare so intently pushed herself to handle what a basic eye test insisted that she shouldn't. Cursed propensity towards perfection though, she couldn't just sit there in a puddle of her own spunk and let her weight and the weight of the other dickmare force it down into the mattress, she would never get that smell out if she didn't do something soon!

"I'm sorry to ruin your fun, but we need to get up now..." Rarity nudged at Sweetie's head, but the persistent little mare didn't want to let go and nudged back down again with her snoot, though jade eyes did drift up towards Rarity rather than stay fixed upon the lengthy spire. "Come now darling, you can't stay there all night can you?" Sweetie issued some sort of muffled sound upwards and tilted her head up and down as if to insist that she could stay there, that she wanted to stay there, but Rarity was her sister and when another nudge was given, she reluctantly relinquished her mouthful.

Rarity was quick to push herself off of the bed and tug her little sister along with her, magically pulling the sheets and bedding free behind her and use the more soaked bottom sheet to wipe some of the cream from their bodies before balling it up and letting it sit beside the bed. That would have to go into the wash before the night was over or else it would permanently bear the mark of the evening that the two had spent together.

"Aww..." Sweetie gave a mournful little sigh and an equally wistful look at the bed, now stripped of all of it's coverings, just a mattress atop a box spring. "I suppose that means that we're done then?" Call it the desire to spend more time, call it pent up need that hadn't fully vented, call it insatiability, but Sweetie really didn't want the fun to end. A nudge of her hips into Rarity that ran the dusky and yet quite firm member into Rarity's side affirming that body and mind were still in the same place.

Rarity couldn't help but roll her eyes, but in that maternal, 'oh you' sort of way that never had any real sense of being cross to it. Sweetie Belle might be growing up, but there were plenty of ways that she was still just a filly at heart. Rarity actually envied that in a way, just the way that Sweetie was subtly rubbing that cock against her side was something that Rarity would never do herself, demanding a bit more than what she'd gotten without actually demanding it. Rarity would have worried too much about being seen as ungrateful to ever behave like that.

"Would you like more Sweetie Belle darling?" Rarity bent down just enough to put herself on eye level with her sister as she spoke. It was the most rhetorical of questions, but she knew that it was important for her to offer rather than just make her sister feel as if she had forced her sister's hand to keep going when she was done.

The response from Sweetie Belle was all the reward that Rarity needed to have. The young dickmare's eyes grew wide and practically sparkled with enthusiasm, her lips formed into a small 'O' shape and her head nodded vigorously several times. "Yes, yes, yes, I really really would Rarity!" Even her sizeable shaft responded with a pair of very firm throbs that bucked the turgid length up into Sweetie's modest chest enough to slap into her bosom, bringing an eager trickle of precum rolling down it's belly.

How could Rarity say no to that? Even though she'd not yet given her any idea of what 'more' entailed, she all the more felt after seeing that, it was the right thing to do. Poor little mare, Rarity actually wondered to herself just how often that Sweetie actually got to have sex if she was so hungry as she was now. Perhaps being seen as too young was a part of it, or too large for some to handle was another? It was all moot point though, Rarity now had it in her head to give Sweetie a night that she would remember for a long long time.

With a flick of her tail and a sway of her hips, the seamstress made her way over towards the nearby wall and braced her hands against it while pushing her backside out in a way that no pony would mistake. She had yet to have her own member flag either, but it was more understandable considering she'd cum but once yet, making it all the more important that she position herself properly, lest she end up pounding that stiff battering ram of hers into the wall itself.

Sweetie's eyes were still wide with eager youthful enthusiasm and they followed Rarity's every move over towards the wall. Likewise eager hands were pressed into equine shaft and pumped up and down steadily, tending to the ache that she had in her loins that refused to go away. For all of her excitement and anticipation, nothing compared to seeing Rarity present herself and lift that perfectly styled swirl of a tail to expose her shapely rear and tight little puckered anus.

*SpatterSplut* The building pressure inside of Sweetie surged forth as her excitement reached it's peak, sending cloudy fluids washing over the floor in a long jagged line, further adding to the mosaic of shiny and milky pools sprinkled atop the hardwood. Her little legs could barely get her over to her sister fast enough even when faced with the challenge of colliding with weighty grey testicles.

"Oh thank you Rarity! Thank you thank you thank you!" The words poured from Sweetie Belle's mouth so fast that they almost slurred together, the pitch of her voice going up several octaves into that excitable squeaking she likely would never shake no matter how old she got.

"Oof!" Rarity knew that her sister was eager, but the speed and force still surprised her the moment that the blunted flare smacked into her posterior. Sweetie's overeagerness proved to be the only thing that kept the impact from going a step further into an instant penetration. She was shaking with anticipation and quite chomping at the bit, so her aim was unsteady, making spanning the slight height difference between the two take several seconds longer than could have been expected.

"S-Sweetie darling, take your time, there's no... Gah!" In her zeal, the young mare had found a foothold against her sister's posterior and rather than try to work herself in steadily, had resorted to a more primal method of pleasuring herself, that being, just throw all your weight into one thrust and hope for the best. Suffice to say, it worked much better than the little mare could have ever hoped, her thick tip spreading Rarity's anus sharply around it's girth and popping inside in it's entirety.

"Ooooooooohhhhhh... Siiiiiisterrrrrr...!" Sweetie's voice bubbled with passion and pleasure all at the same time, her songstress voice allowing her cry of passion to almost seem musical in contrast to her actions. Those actions were to give herself more of the tight and warm feeling that wrapped around her swollen mare meat, and quickly.

The forceful sound of semen hitting the wall and washing along it followed an instant after Sweetie Belle took that next thrust. Rarity had little choice in the matter at all, not that she had actually orgasmed so quickly, but the sharpness of Sweetie's penetration coupled with her incredible girth had pressed quite the milking squeeze into Rarity's prostate, wringing enough semen from Rarity to blast a distinct splatter mark against the wall point blank.

Not at all something that Rarity was used to, it took a bit of her breath away that such a feeling was forced upon her, causing her to gasp several times and her cock to buck sharply a trio of times in a way that it only would when she was indeed cumming. As her eyes began to refocus, they were greeted with the sight of her cum drooling in strands down the wall, leaving very distinct slimy tracks tracing back to it's origin.

Her appreciation for the state of affairs didn't last long, Sweetie was still back there and she was still trying to work herself in deeper in her fervor. Rarity could tell that there was a distinct lack of experience at play now, because her sister was just throwing her entire body into every thrust, completely without any sort of rhythm.

Rarity turned and cast her eyes downwards towards the smaller pony and brought a hand around to cup her little sister's cheek. "Sweetie darling calm down, here, let me help you~" Were she not such a good sister she might have actually been a bit cross with how carried away that the younger mare had gotten, but she forgave it in the name of chalking it up to a learning experience.

Something about the touch and the voice got Sweetie's attention, making her ears wilt a touch with embarrassment as she nodded sheepishly at Rarity. "Here, rest your hand under my leg like this." Rarity lifted her left leg and leaned more of her weight into the wall while guiding Sweetie's arm and hand around to lift the leg a few inches higher and support it's weight. She couldn't expect Sweetie to handle a good deal of her weight, but one leg would be a minor strain at best for the advantage that it gave. As she turned her body a bit, rotating around Sweetie's considerable insertion, she opened up a much better angle of attack, allowing Sweetie to buck her hips upwards with much less effort.

"Now then Sweetie, up and down. Steadily, don't try to go too fast right away, just concentrate on going as deep as you can comfortably and then pulling back, don't worry if it takes a moment or two to complete the motion. Once you get the hang of it you can speed up more and it will make both of us feel much better!"

Those final words, those were what rung the most true inside of Sweetie's head an cut through the fog of lust that had clouded it for a minute or two. Her big sister was being so very generous to her, she didn't want to be selfish and hog all of the pleasure for herself, she wanted very much to make Rarity feel good. "I want to make you cum for me then Rarity, I want you to moan as much as you've made me moan and cum as hard as you've made me cum!" Sweetie was quite determined in those words as she did exactly as she was told, moving with a purpose, making her sister stretch out more, but not punching Rarity's stomach from the inside like she had been.

It did take a few minutes for the young mare to get the hang of her new role, she was inexperienced true and this was a position that she had never tried before, but thankfully Rarity did all she could to make it easy for her. As she grew more accustomed to the range of motion that she could comfortably afford herself, that was when she started to speed up just a little bit, the pace going from a slow internal grind to a very deliberate pounding upwards.

The faster that Sweetie moved, the more that the sounds of sex returned to the room, her balls beginning to sway back and forth pendulously between her spread legs, coming oh so close to smacking into Rarity's hanging pair before slapping against Sweetie's thighs on the return trip with a satisfying solid *thwap!*

For Rarity, this was a rather rare, but delightful experience to be sure. Much of the time, she was the one giving in such a position and with good reason, but that didn't mean that she couldn't let others give back to her as well. The plain and simple fact that right now her little sister was the one behind her pumping that huge dusky spire into her and stretching her, filling her up in a way that she did not remember anyone ever being able to do to her in the past. Then there was that thick vein that strained from Sweetie's tool that somehow had found just the perfect angle to rake against her prostate with every thrust. It was perfect and Rarity dared not change her position for fear that the angle that was allowing Sweetie to turn her into goo remove that rippling pressure.

Rarity couldn't last long like this, she too was eager, though not as eager as Sweetie Belle, but she was just being touched in all the right places inside. Every last button about the whole scenario, from how cute her little sister was, to how this was something of a taboo, to how absolutely hung that Sweetie was, to how she was being stirred up, it was pushing her to the brink, making her pant, her body strain and her cock buck.

"Sweetie Belle... O-Oh... Oh darling..." She couldn't resist anymore, it was too much for her to take. "You're going to... Oh don't stop... Deeper... Mf... You're going to make me cum!" Rarity's body stiffened, pushing itself into the wall and the floor like a brace, her voice betraying her ecstasy as words stopped coming and instead were replaced with mewls and gasps and feverish cries.

For the first time since she'd entered the room, Rarity was the one to cum before her little sister, spraying torrential ropes her seed across the room to further sully the quagmire of sexual release that it had become. The impacts of Sweetie's testicles into her thighs soon became nigh drowned out out under the overlay of Rarity's bountiful balls raining their contents across the floor again and again.

That first mess that Sweetie had made all by her lonesome was quickly was being mirrored and then some by her elder sister, proof positive that the two were the beneficiaries of some very good genes. Almost a half of the floor space had one or the other sister's spunk spilled across it at some point and there were an abundance of areas where there was no hint of the wood anymore, simply a widespread sweeping whiteness that was seeking to mingle further with more of it's own.

Watching Rarity jizzing across the room like that got Sweetie off even faster than the friction of pumping into Rarity's body. The knowledge that SHE had done that, made her pretty, lovely big sister who she looked up to more than anyone in the world cum and cum so very hard and so very much made her mind positively tingle.

She wanted to speak, to say something, but somehow Sweetie couldn't do it, it would interrupt the crooning of her elder sister, music to Sweetie's little ears, music she just couldn't get enough of. She wanted to tell Rarity that she was going to join her on that plateau of felicity, but the words wouldn't come. It was all that she could do to let out a muted, throaty little catlike mewl before throwing herself over the edge as well, driving up into Rarity's body with every last ounce of strength in her body, pushing herself up onto her tippy hooves and even lifting Rarity just a tiny bit in the process, only allowing her to balance on half of one of those mallowy hooves of hers.

There was no care given for how much or even how fast that she poured herself into her sister, the only thing that Sweetie cared was that she was doing it, that she was once again sharing something with Rarity. It didn't matter at all to her that the stiffness of her joints was going to make her feel sore when she was done, nor did the fact that the tremendous volume that she was pumping into Rarity's ass was making her stomach bulge, not even the fact that every time she ejaculated into her sister a burst of it splashed out across Rarity's milky plot, spilled in strings and fat globs to the floor or even streamed down the little mare's darker meat.

In her mind, Rarity had been fully right about one thing, this was going to be a night that Sweetie Belle was not going to forget for years to come, if ever.

Chapter 5

"Ah... Aaah... Hah... Sisterrrrr..." At any given point in time, one mare or the other uttered those words,though they often ended up lost in the myriad of the sounds of sex. If seed wasn't being spewed across the floor by Rarity, it was being forced out of her stretched out backside courtesy of another gush from Sweetie Belle. The soundtrack of their union alone would have been enough to get anyone who was a fly on the wall off themselves and it continued for quite some time before Rarity came down from her orgasm and Sweetie Belle quickly followed, rendering the splashing gushing noise of thick semen to a mere trickle, the last drops of paint in the bucket as it were.

"Ooooooohf..." Sweetie's rigidity caught up with her as the rush of sexual tension wore off, the buildup of lactic acid in her muscles causing her fingers to lose their grip on Rarity's hips and her legs to wobble and then crumple under nothing more than her own weight. Down went the little mare with a soft thud and a bit of a splatter, her tush smacking flush into the puddle between her legs that she'd been adding to.

"Hah... Hah... Mnnf..." Sweetie's breath came in cute little chugs as she did all that she could to recover some of the energy that she'd spent. She felt warm and good all over, a soft flush spreading over her cheeks further giving evidence of the exertion, along with a few beads of sweat that were welling up at her brow. "Oh yes..."

Rarity herself slumped into the wall, but kept her weight off the floor with one arm pushing back, her opposite extending the afterglow as it pumped along her still rather turgid white member. Alabaster digits dug in a few times against the bulging underbelly to wring out the last bits of her climax, producing some quite large strands that went missing amidst the mess that she'd helped Sweetie Belle make. All the while her poor stretched out plot leaked the leftovers of Sweetie's impressive climax down along her leg, forcing her to leave her tail hiked high to prevent staining it's lower half with whiteness.

The elder of the sisters was the quickest one to recover, a push away from the wall necessitating a slight stutter step to keep her left hoof from slipping into the slimy mess she was standing in. "Well Sweetie Belle, how are you feeling now? A little better?" Her little sister certainly looked like she was going to need some time to recover from the way that she was panting, her more modest bust heaving with each and every breath that she took.

"I do Rarity but..."

"Surely you don't need to cum more STILL darling?" Rarity looked down at her sister with a mix of surprise and disbelief. How much more could Sweetie really need? Especially since there did seem to be a bit of a sag beginning to form in her little sister's member post orgasm.

"N-No I mean..." Sweetie played her index fingers together and tried to both look her sister in the eye and not look her in the eye at the same time. Whatever she wanted to say, she was struggling to actually get out. "Well... You're still hard looking and well... Um, I want to make you feel as good as you just made me feel is all!"

"Oh. Well I'll be fine Sweetie Belle, you don't have to worry about me at all, big sister is more than used to having to let an erection go down from time to time." Rarity chuckled and did all she could to wave her hand and blow off the offer rather than put her little sister out. "Remember last fall when I got all those orders from my fall line? Well big sister had to ignore quite a few erections in the morning or after a shower because there was work to be done! It's not a big deal, truly!"

"But big sister..." Sweetie, never one to mind a mess, pushed her dainty little hands right into the cum soaked floor, pulling long strands of her own ejaculate with on the way up, only to leave her with cum icicles on her fingers that she shamelessly wiped off upon her ivory backside. "I want to return the favor, you're always so generous with me and... Well I thought that you would scold me for what I did and instead you helped me, made me feel so good and... I don't care if I have to clean the mess all by myself, I just want to thank you for it is all!"

"Silly little Sweetie, you really don't need to, you don't, I'm... Awfully big for you..." Rarity had a legitimate concern there as she was really so large that she looked like she might stretch her little sister out to the point of ruination if her little dainty plot even tried to take all of that horsecock!

"I don't care Rarity, I really really REALLY want you to~" Sweetie did her best to look sultry, turning and swishing her two toned tail, flagging it and holding her cheeks apart with her hands, almost forcing herself on her sister, doing all that she could to push her posterior against the towering ivory member and grind along it. "Mmm, you're so warm sister, and so thick too, I'm sure that you'll feel just perfect inside, I don't mind if I'm sore afterwards!"

Rarity was still on the fence about allowing her little sister to even try such a thing, but Sweetie, emboldened further by the lack of her big sister saying anything to the contrary or actively doing a thing to stop her, continued to press. "I can only imagine how full that you'll make me feel too~" Sweetie scooched herself back a few more inches until she was so flush with her sister that Rarity's shaft angled itself nearly vertical.

The elder sister took a half certain, halfhearted step backwards, only for Sweetie to push flush again in a flash, the little mare was too sincere or too lust drunk to take no for an answer and Rarity had to admit to herself that Sweetie was a very lovely little mare in her own right. Common sense slowly gave way to desire and Rarity sighed amidst the last vestiges of her protest crumbling inwards. "Very well, but at least let me lie down so that you can take me at your own pace, that way you can pull off if it becomes too much for you."

It took a while for Rarity to even find a good spot to lie down at all, there weren't many spots on the floor that didn't have puddles of cum or at least stray sprays or droplets upon it large enough to lie a pony upon. Eventually she found one and settled herself into it, taking care to not let her mane or tail stray into the mess that surrounded her on all sides.

Sweetie Belle was all over her sister the instant that Rarity had settled down, pouncing upon her opportunity by pushing herself between Rarity's cock and body and then stepping backwards, using her frame as a wedge to force it upright once again.

"Ooooh, big sister you have such a biiiiig dick~" Sweetie's adorable voice trilled as she began to grind her back half into the towering shaft. A single hand slipped behind and was used as a brace, enabling the young mare to slide herself up and down with gyrations of her hips that made Rarity worry about her little sister sometimes. How a little pony like Sweetie Belle would know anything about using a dick like it was a stripper pole was beyond her, but hopefully it was a mere coincidence that Sweetie was doing it like that.

If Rarity had been flagging at all, her sister saw to it that she was not going to stay that way, the rubbing, sultry actions and words had her throbbing despite her initial reticence. A healthy firmness shoved right back against Sweetie, trying to force the alabaster pole back into it's normal place, only to provide a much better support for Sweetie to work her body back into it with even more abandon.

"Oooh, I just can't wait any longer Rarity, I want to feel you inside of me!" Sweetie backed up even further, her balls dragging along Rarity's shaft as she went, angling Rarity further and further back until she could feel the tip flared out just past her eagerly twitching ashen pucker. Sweetie didn't hesitate for a moment to bring a hand down and cup up under the underbelly of her sister's dick and make it press firmly into her hole, smearing whatever lubricant that Rarity was producing against her. The little mare continued her movements, wisely making about a dozen passes to ensure that Rarity's flare and every inch of the area from her bulged taint to her asshole was sopping with precum.

Even in Sweetie's mind she knew that this was going to be a stretch and the rubbing had been a bit of waffling on her part, staring off the end of the high dive into the water below and gathering up her courage to take the plunge. Before she had waited long enough for Rarity to sense her hesitation though, Sweetie threw herself into the act in an effort to get it over as quickly as possible, pulling up with that hand, angling her backside and shoving it down with all the might in her body.

*SQUELCH!* Plot stretched faster than it likely should have, fuck flesh and precum noisily invading the young mare's insides and leaving her ass stuffed beyond anything that she had ever even thought possible. "RAAAAAARIIIIITYYYYYYYY!" Sweetie's shriek was loud enough that it would have even been audible outside of the boutique, but the determined, or perhaps more accurately, stubborn little mare, rather than pulling back, pushed her butt down again, all the more firmly, not giving Rarity a chance to pull back and slip her dick out of her squealing sister.

Just as Rarity had been brought back to full rigidity, Sweetie too went from the half hard state that she'd been in while rubbing away and trying to be seductive towards her sister into the raging ashen beast that it had been before. The stuffing of Rarity inside of her so deeply that Sweetie swore she could feel her sister's flare somewhere in her stomach and the outright assault on her prostate gave Sweetie the most imposing, raging hard-on that she'd had all night long.

The intent to make Rarity feel good was still in there, but the delicious fullness and the dull ache inside of her from being stretched far beyond anything Sweetie had ever experienced led the little mare to suddenly care much more about her own needs as well. Her bubbly little butt began to lift up and down as she braced herself against the floor as best she could, trying to slide herself along Rarity's dick as eagerly as possible. It took some work to even move much at all, but the longer that she was nigh impaled like that, the more that her body accepted it and loosened up, allowing her to slip upwards and downwards a few inches at a time, gradually managing to make more and more appear and vanish until she was sliding a foot or so of Rarity in and out with every cycle.

Rarity just sat there, gnawing upon her lower lip while watching Sweetie work, forcing herself to not thrust up, to not stretch her sister to her limits like she'd done with many a mare in the past. It would have been ultimately futile to try because Rarity was indeed, too large for Sweetie Bell to take all of. Groin to plot, there was a good foot of her engorged log of mare meat that never even came close to being worked into Sweetie's body. Instead it served as more of a firm base that let Sweetie squat down and bounce up upon.

Watching Sweetie trying her hardest was an example of lewdness in its basest form, she squeaked, squirmed, grunted and gasped as she worked. The whole time, her ashen member spent flopping up and down like a toggle switch, slapping Rarity's breasts and her own, playing the most lascivious game of ping pong imaginable. Some of those squeaks Sweetie issued coming courtesy of that huge dick of hers when it smacked her right in the face. Sweetie's modest chest had nowhere near the airbag like cushioning power of her elder sister's mallowy large bosom.

The impacts did detract from the experience a little bit even if it was adorable to see Sweetie working hard enough to cockslap herself over and over, only to work right through it like she didn't mind. "Mfn. Sweetie darling, slow down just a little!" Rarity managed to catch her sister's shaft as it came down to impact the larger bust once more and hold it in place to keep it from springing upwards. "Here darling, hold it like this, I'll make you feel even better!"

Sweetie paused, surprised at the change and looked down at her big sister curiously, but did comply after the short hesitation, pushing both her hands down with all the force she could muster against a tool that wanted to spring right back upwards and would have if it wasn't being forced to do the opposite! It was then that she saw what Rarity was making her do, her generous, gorgeous sister pulled her breasts apart so that Sweetie's girth nestled into them and then pushed them back inwards, wrapping titflesh around dickmeat like the warmest and most plush of fucksleeves.

"Now rock your hips darling, back and forth like you're trying to fuck my tits." It was a simple command and one that Sweetie very happily obeyed, shortening her own strokes against Rarity with her hole, but making them even more frequent also now that Sweetie had a gage to work by of pushing forwards just enough to bump into or come near Rarity's lips and then pull back until her flare had disappeared into Rarity's cleavage.

It could not have been any more perfect the way that Rarity saw it, and the slightly reduced friction allowed her to hold out a little longer than she would have been able to while Sweetie was furiously bouncing her vice like anal hug up and down. But she could feel it building even now, another orgasm that her body was more than eager to give in to and feed to Sweetie in suppository form.

Sweetie could tell it was coming as well, this was not the first dick she'd ever had, she could tell what the signs of an impending orgasm were just as well as the next mare. The way that her sister was tensing, the way that her cock was swelling up, bulging inside of her, it all pointed to one more release from her big sister!

"Oooh, you're going to cum aren't you sister? You're going to blow your huge fat load aren't you? Oh, oh cum for me big sister, cum for me Rarity, I want it, I want your hot sticky cum in my ass, I want to feel every drop inside of me!" The way that Sweetie spoke it was as if at this moment, the sexiest thing in the world would have been for Rarity to simply do nothing more than sit there and blow her load while Sweetie milked every drop out that she could possibly manage!

Rarity couldn't have held back even if she wanted to. She'd been worked up to the point of no return and right now she was swimming in a haze of her own desire to the point that she just wanted nothing more than to pour semen into Sweetie Belle until the eager, greedy, naughty little mare couldn't so much as ask for a single drop more. She just wanted to stuff her dirty little sister with jizz until all she could do was mew and gurgle.

*GLORB!* That was the sound of cum exploding somewhere deep inside inside of Sweetie's stomach, causing the young mare to gasp as the force of it ramming into her belly caught her off guard. She didn't get a chance to catch her breath though, her sister was bountiful and 'generous' with good reason, those huge nuts were now properly worked up to a full release and they did so with fervor. Again and again Sweetie's insides were assailed with buckets of cum until just as she'd done to her big sister, Sweetie Belle's stomach started to bulge with the excessive volume.

Sweetie's cute little voice had started out as a trill series of 'yesyesyes, cum, cum for me Rarity, cumcumcum!' but the more that Rarity came, the more the little mare started to just squeak and gasp, trying to find her voice, to locate words for this. She never managed to do so. The only sound that Sweetie was able to muster was that of a loud moan that started in the back of her throat and grew louder the longer that it spilled from the songstress' lips. A decidedly ecstasy laced "aaaaaAAAAAAHHHHHHHHH!"

There was no proper way for her to convey the rapture that was going through her, the pleasure ensorcelling her mind and body from all of it and once more, the little mare found herself going rigid, her mind slipping away from herself and her vision going wonky at the corners from an impending climax.

Rarity saw the little mare's cumslit yawning open wide and somewhere in the recesses of her brain a reflexive instinct to shut her eyes triggered and not a moment too soon either. A tsunami of cum exploded into her face at point blank, catching her right across the mouth and muzzle, the stream pouring and pouring for a stunning amount of time as it covered her face, buried it in cream, sopping into her hair and pulling it to the ground, leaving her laying in a puddle of the stuff from the shoulders up.

Sweetie's cry of pleasure was cut off again as Rarity once more ejaculated into her sister, bulging poor Sweetie's stomach out to the point that she could feel it pressing against her arms, making her trail off into a 'AAAAHHHH-Ngllng!' For a moment she went hoarse, her mouth hanging open unable to make a sound even though she was trying, air leaving her throat with a soft hiss instead.

The next load Rarity had fixed that little problem for Sweetie very nicely, finally reaching the limit of what Sweetie could contain and sending it surging down the all too tight union in creamy, glue thick ribbons that began to adorn the base of Rarity's cock, her thighs and her balls. All of that somehow managed to make Sweetie pull in a deep breath and then squeal out in the same mind rattling 'AAAAHHHHHHH!' that she'd been droning on with before.

Just in time too, for another creamy, heavy gout of pony spunk surged out in retaliation over Rarity's face, washing in sheets over already snow white flesh and painting what wasn't the same fully this time around. No traces of Rarity's blush or eyeshadow were left as Sweetie hosed her sister down, making Rarity look like she was wearing a differently colored mud masque. Likewise, the deep velvet of her mane was long gone, caked with so much semen that she looked like she'd dunked her mane in a vat of conditioner and let it soak.

So much for clean spots in the room, so much for keeping herself or her sister presentable. Both mares were going to need a LONG shower after all of this, especially the eldest and the room was going to need to be scrubbed down floor to ceiling and even then, there was no promise that the overwhelming scent of sex that hung heavy in the room like Rarity had hosted some sort of orgy, would go away anytime in the near future!
