An evening with Sweetie - by Rhurrs

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.
