An evening with Sweetie - by Rhurrs

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.
