Sister's Love

Pumpkin gasped when she felt her twin brother Pound nuzzle against her filly parts, apparently completely foregoing using his hooves, then felt the tip of his tongue rub against them. Pleasure instantly shot up her spine as the rest of his tongue soon after did the same, Pumpkin’s eyes rolling back as she felt pleasure like she’d never felt before, a deep moan escaping her throat as he started to sloppily lick her.

Pound slowed, then stopped, as he heard that moan. “Are you OK sis?” he asked, a hint of worry in his tone, “I’m not hurting you, right?”

"N-no...it feels really nice and you can keep going, it’s just..wha-ha-are you doing?" Pumpkin asked, her back arching a bit off of the bed at the sensations, feeling her little nub wink in response to its hood being stimulated as Pound had resumed after hearing it was OK to.

"I'm licking your fillyhood like you wanted...you taste and smell really good down here! Do you like it?" Pound asked, getting an eager nod from his sister, "Do you want me to keep going?" Another, more eager nod followed.

Pound nodded himself, slowly licking her vulva, testing his limits with this new activity. He felt the lips’ soft yet firm texture on his tongue, Pumpkin’s juices starting to pour en-mass from her and lubed his motions well as she looked back at him through her legs, her eyes lidded and a goofy smile on her face.

“Wow, it looks like that’s making you REALLY wet down there!” Flurry commented, hearing quiet, wet squishing sounds each time Pound licked his sister’s honeypot, feeling her cheeks flushing hot as she was reminded by them of when Pound‘s penis was inside of her.

It wasn’t long until Pumpkin’s pussy's petals parted partially, the young mare groaning softly as she felt his tongue cover her vulva with each pass over it, her clit occasionally winking when its home was licked. She felt that burning feeling growing slightly, but the pleasure caused by his licks helped to counter that growing need.

Flurry watched from the sidelines, fascinated as she watched him lick his sister's crotch, angling herself to get a good view of the action. "So, how's she taste?" Flurry asked, Pound stopping to lick his lips and speculating her question.

"I donno...but I really like it. You taste awesome sis!" Pound said, his arousal-stiff wings giving a soft semi-flap in response, her scent pervading his senses, driving his arousal higher as his cock hung stiffly beneath him.

"Could you keep licking p-please? F-Faster? Y-you can go in a little now...and that part at the top feels really good when you lick it!” Pumpkin asked in a dazed tone, Pound nodding as he slowly pressing his tongue back between Pumpkin's now-spread petals in response, getting a loud gasp from her as she felt his tongue only just penetrate her. His tongue was coated in her slick fluids as he slowly pressed in just a bit more as he spread her lips wider, ever so slowly getting deeper into her virgin passage. Pound was rewarded with heavy panting as he pressed further in, then another quiet, satisfied moan.

Pound’s member was hard again, the spicy scent of his sister and aroused scent of Flurry alongside making his nostrils flare, the situation he found himself in driving his arousal higher with each lap. His member was giving the occasional flex and bob painting his belly in its slick emissions, a testament to his sheer arousal.

Flurry was now laying to the left side of Pumpkin, admiring Pound’s hardened member and deep-grey ball-sack, before her eyes then focused on the two small pink-and-yellow nubs that were her teats. “Hey Pumpkin, can I try something with your teats? I think you’ll like it.” Flurry asked, getting a desirous look and nod from Pumpkin, who seemed to be unable to communicate past pleasured little moans and soft whinnies.

Permission given, Flurry gave one of the nipples a soft lick, getting a quiet, muffled yelp from Pumpkin’s throat, her mouth busy biting her foreleg to hold in as many sounds as she could. Pound stayed still for a moment, letting Pumpkin recover slightly before he started to move his tongue up and down, the simple but steady movement making her squirm in her ecstasy. He was rewarded with a shudder as Pumpkin tensed up more, her pleasure spiking higher as her brother’s wonderful muscle worked its magic along her entrance and Flurry’s along her sensitive teats.

Moments later Pumpkin felt her groin start to burn in a more intense way, her juices flowing like a waterfall now onto the bed’s quilt as she felt Pound’s tongue lick against her smooth entrance, feeling muscles she’d never used before today starting to clench down harder on themselves as her pleasure rose ever higher; her climax fast approaching. “T-tingles!” Pumpkin managed to sputter out, her voice drunk on pleasure and Pound’s pheromones.

This announcement, along with her increased clenching on his tongue, only spurred Pound on as he increased the tempo of his tongue's movements, instinctively working to make his young mare ready for him; ready to be bred. He continued licking her now-constantly winking clit, realizing her reactions when he did; how she’d tremble and give quiet, pleasured whinnies

When Pound hit that magical spot, Pumpkin felt her pleasure spike exponentially and caused her to almost scream in ecstasy, biting her foreleg until it was nearly bleeding. However, her scream didn't have a chance to get out, getting caught in her throat and only a choked whine managing to get out instead. She started to tremble now as his tongue continued to lap her winking clit, Flurry even still licking over her teats. Intense blasts of sensation joined the constant tingling throughout her each time her tongue hit found a nipple, making her tense up as they rubbed her most sensitive spots.

Moments later, Pound and Flurry’s dedicated ministrations finally paid off as Pumpkin felt those muscles squeezing frequently again like when she’d earlier used her hoof while Pound was putting his milk-like fluid in Flurry, the same intense tingles roiling in her and boiling over.

Pumpkin cried out as she bucked her hips hard against Pound’s muzzle and her hips arched completely off the bed, her muscles trying to pull his muzzle deeper into her. She started repeatedly grinding him against her swollen lips while she whimpered through her most intense orgasm yet, heavenly pleasure wreaking her as she tensed; her whole body virtually convulsed, her passage repeatedly clenching down on the warm, squirming tongue that had brought it on as her juices splashed against Pound's muzzle. Her thick, slightly yellow and heavenly tasting filly juices came out like a waterfall against Pound's muzzle, with enough force to make him lightly recoil, Flurry meanwhile still enjoying licking both of her tiny nipples.

Pound felt his penis now throbbing and slapping against his underbarrel, making a loud smack sound out as it flexed strongly at the stimulation of making his mare climax, her scent increasing twofold in intensity; telling his animal mind she was now ready for him. Pound was gently humping his hips in the air as he felt a squirt of his pre-cum shoot out and paint the quilt with his musk, feeling only light pleasure himself as Pumpkin continued to squirm and grind against his muzzle in ecstasy. He felt a wetness squirt from his sister and onto his muzzle, making him jerk back a bit, but his licking never stopped. He lapped up her surprisingly flavorful fluids, cleaning her vulva gently until she finally stopped trembling as hard and calmed down some.

Flurry had been licking Pumpkin’s small nubs all the while, as though memories of being a newborn guided her to suckle on them, trying to coax them of life-sustaining milk...even if such wouldn’t happen from such a young, and more importantly not pregnant, mare. Nonetheless, as she heard Pumpkin cry out, she slowed her licking and looked up at her face, seeing the absolute, blissful expressions on her face as she got her tingles. As she remembered at this time just how that warm, sticky heaviness of Pound’s cum still sitting pleasantly in her lower belly had gotten there, her own slick fluids were flowing again, the scent of Pound’s musk and Pumpkin’s own arousal reactivating her breeding instincts.

Pumpkin's trapped scream of ecstasy from before died in her throat as she collapsed to the bed, her tingles fading and a soothing feeling instead spreading through her, relaxing her as she shut her eyes and a small smile crossed her face. As Pound stopped licking and looked up at his sister, his muzzle still glistening with her yellowish filly cum, he saw her blissful, intense expression, complete with a heavy blush...and realized it looked very similar to how Flurry’s had when she’d clenched down hard on his colthood.

Pumpkin moaned raggedly as Pound continued to please her, her fillyhood still softly squeezing its muscles on occasion. She felt as he softly licked her clean as her afterglow started, making her feel that much more relaxed and comforted. “W-wow little bro...” she somehow managed to stammer out once he'd finished, still feeling minor twinges and sometimes full contractions through her vagina as her orgasm slowly waned and afterglow continued, “T-that...was intense...n-nothing like with my hoof.” Pumpkin said, before looking over to the pink-coated filly as she realized something. “F-Flurry...y-you licked my teats...”

Flurry looked a little worried, nodding her head. “Well, you said I could...did you not like it?” she asked, before seeing the soft, comforting smile on Pumpkin’s muzzle, Flurry giving one in turn.

“No...I think that’s what made it feel so much better. T-thank you both.” Pumpkin said, before laying back down to rest.

After his sister calmed down some moments later, as did Flurry, Pound still felt his own needs, still fully erect and pre-cum drooling from his flare. "So, are you ready to do the grown-up hug now sis?" Pound asked, his muzzle still saturated with his sister's now-dried filly-juice and her looking much more relaxed after she'd gotten more good tingles, the unpleasant tingling, burning, itching feeling in her lower belly temporarily sated it would seem, even if it was still there.

"M-mmhm..." Pumpkin replied as she followed her instincts and presented while still on her back, her tail drifting to the side. Instead of mounting her like that, however, Pound’s instincts demanded something else. Softly nudging her into the proper breeding position, Pound made Pumpkin roll over and stand on the bed, her rump facing Pound, and on instinct she flicked her tail up to reveal her glistening gem to him as she knelt her front half down.

Pound quickly saw that his sister's vulva was coated in her shiny fluids and his saliva, her little nub blinking in and out, stimulating his animal mind that much more and making him virtually prance in place and paw at the bed. Her legs locked on instinct and lightly trembled as Pound approached his sister's presented treasure, with her very soon feeling his hot breath on her sex as he sniffed it and exhaled one last time, making an involuntary shudder go through her as her clit winked to him in response. “I-I’m ready....just...be gentle.”

As he saw her nub 'blinking' to him the same way as Flurry's had, Pound suddenly climbed over Pumpkin and mounted her, giving Flurry a perfect point-blank view at the action from down below.

Flurry meanwhile, wanting to get in on the action even as she still felt the heaviness of Pound's 'colt-milk' deep within her belly, had slid under the two on the floor from the left, laying so she could get a good view of them from beneath. Pound and Pumpkin both lay on Pound's bed, with him leaning over her backside, Pumpkin's face down and plot up, with Flurry's head directly under her midsection, her own back legs spreading out from Pumpkin's side and a hoof reaching down to play with her own fillyhood. Flurry gasped in amazement because all of this had happened to her before but she couldn't see; now that she could, she could see how big his member was up close and could understand why it made her smaller body bulge out so much when it was inside of her, and why it had felt so utterly filling.

"Hey!" Flurry yelped in surprise, Pound's member missing and bumping Flurry’s cheek with a missed thrust and left a slimy trail of pre, but Pumpkin only moaned and raised her rump on reflex as that same thrust grazed one of her teats, feeling Pound's hooves wrapping around her hips so perfectly as his underbarrel ground against her croup, his willy grinding between her teats as he unintentionally teased her.

"Mmmmm..." Pumpkin whimpered out, grinding back against him eagerly, her clit winking, not even knowing why she was doing it, but with it feeling so utterly right to do.

Flurry had noticed Pumpkin's slightly larger, more matured teats glistening with her sexual fluids again. Curious, she took a lick on one's nipple, earning a backwards hump from Pumpkin as she did. Figuring that was a good thing, she licked again, now tasting the fluids on them, finding that it tasted sweet and very lightly like cookies and roses alongside the prominent flavor that she couldn't really identify as anything besides 'tasting like Pumpkin'.

Pumpkin moaned again as moments later she felt her brother's tip push against her slit once he pulled his hips back and aimed, letting him feel her clit wink against his flare, inviting him into her and giggling about how it tickled a bit. Pound only too eagerly took that invitation and slowly thrust into his sibling's canal, the smooth, well-lubricated entrance of his filly welcoming him in.

Pound found that she was even hotter on the inside just like Flurry had been and, despite only the very tip of his flare being inside of her, it felt amazing. "S-So hot inside..." he whispered, unsteadily thrusting his hips forward, before hearing a soft whimper from Pumpkin, the latter feeling something parting within her and his entry was followed by an intense, unpleasant stretching sensation as he took her virginity just like that.

"Hey, you OK Pumpkin?" Flurry asked as she heard a quiet whimper from Pumpkin as she watched the thickest part of Pound's penis slowly go into her, remembering how it'd hurt when he'd roughly put it in her for the first time. She noticed that Pumpkin's belly didn't bulge as obscenely where Pound put his penis into his sister like it had with her, even though there was still a visible bump in Pumpkin's lower belly, with this slightly puzzling the younger filly.

Pumpkin quickly noticed that it was indeed very uncomfortable where Pound had entered her, the slightly painful stretching feeling that Flurry had described while they'd bathed quickly making its presence for her too; however, she'd had the luxury of being prepared, unlike poor Flurry going in blind. She gritted her teeth as she got used to the feeling of her vaginal muscles stretching out for the first time alongside the feeling of that part of Pound inside of her, the top part of his willy feeling like it was nearly splitting her open as her muscles squeezed against it seemingly in retaliation.

"Y-Yeah, I'm OK. It doesn't hurt for me like you said it did for you...for some reason? It was just reeeeeeeeally uncomfortable!" Pumpkin said when the uncomfortable stretching had subsided, leaving only the filling and pleasantly spread sensations behind. Sensations she was quickly growing to like.

"So, how's it feel? Are you OK?" Pound asked his sister, able to control himself more now that he had some experience and wasn't running purely on instinct like he had been with Flurry, not to mention he'd already blown a load in Flurry shortly before; noticing his sister's discomfort and responding by stopping, "Can I go in more yet? I'd really like to go all the way in. You feel really, really warm inside...and not as tight as Flurry was, but a lot more wet and warm...and you kinda...smell nicer too..." Pound felt her insides seemingly form-fitted and gently rippled over his length, a small inner ring just past her entrance squeezing him tightly, as though it were tightly masturbating him inside of her.

"Y-Yeah, sure. It doesn't feel like you're...yanking me apart in there anymore..." Pumpkin said, with Flurry then watching from below as Pound slid more of himself into his sister, then past his middle ring. Both ponies moaned as that sensitive ring had slid in and grazed her clit, before finally feeling that he was fully inside of her, his hips meeting and encasing hers.

"Wow, you took all of him inside of you!" Flurry said in a tone of awe, seeing only Pound's ball-things hanging now and pressed to Pumpkin’s stifles, "I could only take up to just before his ring-thingy! It doesn't look like you're bleeding either. Weird..."

Pumpkin, however, couldn't respond. The feeling of Pound fully inside of her, filling her whole fillyhood as she softly squeezed around him inside of her, was indescribably satisfying. It seemed to somewhat soothe that unpleasant tingly-burning feeling that had been irking her since Pound had finished with Flurry, though it still was there.

"Can...can I start moving my hips?" Pound asked after resting for a while and feeling Pumpkin’s wet heat surrounding his entire colthood, getting more fervent nods from Pumpkin and nodding himself before doing just that. He pulled his hips back and shuddered at the sensations it caused.

As the other two were now getting into it, Flurry looked up and realized just what a great view she had of Pumpkin from beneath them. The unicorn's clit winked rapidly as she took a male, her brother, into herself for the first time.

“Y-your body really likes having me inside you I think...” Pound cooed as he felt Pumpkin’s hot walls squeezing him from base to tip, “It feels like it’s giving me lots and lots of hugs inside! I-nnnng-I r-really like being inside you too!”

“Y-You f-feel really good in my filly place P-Pound! K-keep doing that...thing with your...thing!”

"Wow...so this is what it looks like..." Flurry said as she leaned up closer, getting a good look of the siblings' lewd joining, remembering back to her own time being filled in such a way only an hour ago. As she placed a hoof on Pumpkin's lower belly, she felt a hardness moving in the same motions as Pound's hips were, with that leading her to the conclusion that she was feeling Pound's penis moving inside of Pumpkin’s tummy, feeling a big bump of his thick tip, followed by a lull in size, then another smaller bump of his ring and only more smoothness until he hilted her again.

"Pumpkin, I can feel him moving inside of you Pumpkin! That's so cool! It makes my fillyhood all wet too..." Flurry said, before sliding a hoof down her own chest and belly, starting to rub her winking pleasure button with a hoof. She moaned as the feeling of it winking into her hoof caused her large wings to extend, Pound only moaning deeper as her wing’s feathers ended up between his legs and tickled his thighs and balls.

Pumpkin only responded with a grunt as she felt Flurry's adult-sized wing brush along her chest, awash with relief as she felt Pound penetrate her again and again, her whole body trembling at the instinctively-right feelings of being filled full by a stallion while she was itchy-burning inside...seemingly just what she needed. Pumpkin was winking rapidly, a long string of her thick feminine fluid drooling out of her, down her left teat, before then dripping down onto Flurry.

"Hey...you're dripping on me Pumpkin..." Flurry commented as more of Pumpkin’s feminine fluid drooled down onto her cheek, and she was answered only by a deep moan from her, all of this stimulation encouraging her to light up her horn and form a magical representation of Pound's colthood – an easy task despite her being only a filly, given her vast Alicorn magic reserves – as she looked to the source for reference each time Pound exited his sister. After the magic copy was formed, Flurry quickly pushed it inside of her marehood to its limit after a quick test to make sure it was safe and clamped down on it inside, shivering delightfully as she felt filled once more, actually finding she could touch her clit with the top of the medial ring with the slightly smaller replica...something she fully intended to exploit.

The wet, squishing sound of the two siblings screwing above her sounded throughout the room, as well as Flurry's own wet schlicks as the solidified magic dildo slid in and out of her fluids-soaked passage, the sounds only further stimulating the three involved foals. Flurry opened her mouth, taking one of Pumpkin's hard nipples between her lips again as she remembered how much Pumpkin had loved it during their earlier playtime, earning a shuddering breath from her, the strong flavors of 'Pumpkin' and a new 'male' flavor intriguing her.

As Flurry watched Pound thrust into his sister once more, and again, Pumpkin's clit answered with a wink each time, with Flurry meanwhile continuing to slide her magic-formed dildo in and out of herself at the same pace as his thrusts. She loved the minor tingles of the magic-on-flesh contact and how it pressed what was left of Pound's boy-milk further up into her again, making her let out a contented sigh as she squeezed down on it when she hit a particularly good spot. She also used her hooves to softly rub her teats, enjoying very much the added sensations it gave to her, multiplying the pleasure she felt in the spreading of her foalhood.

Pound felt Pumpkin's incredibly hot, tight tunnel kneading his entire length, only urging him to hump that much more; the musky scent coming from his sister driving his unsteady thrusts to continue without his conscious input. Flurry reached her muzzle up and started to lick Pumpkin's teats again, earning deeper moans from her, with that feeling incredible to Pumpkin while having Pound humping inside of her. Pumpkin didn't know why Flurry licking her there felt so good, but she knew she didn't want her to stop. "K-Keep licking there, Flurry! Please!" Pumpkin whispered out, her hips now rocking back to meet Pound's hips on instinct, wanting each thrust to be as deep as possible into her.

Pound's motions sped up as he felt Pumpkin contracting around him harder when Flurry would lick her teats, "T-That f-feels r-really good Flurry! P-Pound, this...w-wow!" Pumpkin exclaimed as she was having her teats licked while getting her brother's colthood rammed into her again and again, Flurry meanwhile enjoying the salty-sweet-musky mix of her two friends' juices.

"S-Sis...you're so wet...” Pound said in a lustful whisper, her musky scent wrapping around his brain as his mother's had the previous night, driving his hips to pound his cock into his sister's hot wetness again and again, each time he hilted bringing pure bliss to the young colt as he throbbed and spent more pre-cum into his sister’s passage.

"I'll s-say she's w-wet! It's like a f-fountain down here!" Flurry said, licking and lapping away, the two different tastes of Pound and Pumpkin – Pound's being more masculine and bold, while Pumpkin's was equally as musky, but also more sweet – mixed in her mouth, as well as what she missed drooling down onto her chest and neck; not that she minded of course. She then moved her muzzle to Pumpkin’s lower belly, licking along the bump that Pound’s penis made in her belly, feeling that rock-like hardness moving beneath the soft fur and supple flesh.

It wasn’t long before Pound lost the rhythm of his thrusts, his hips jerking even harder, his tip tickling the end of his sister’s tunnel as he started flaring. The feeling of his sister’s inside place wrapped around and gently milking from his base to his tip each time he hilted, her clit winking frequently, while also watching Flurry spread herself open with her magic while tending to Pumpkin’s undercarriage... all of the stimulation built up swiftly.

Within a few seconds, Pound had lost all control of himself, his namesake coming to light as he roughly pounded himself into his sister time and again, making her whole body rock with the force of each. Pumpkin herself was lost to the moment, her back legs trembling on occasion, feeling her own body tensing up. “B-bro! I’m feeling...everything’s...tight!” Pumpkin stammered out in the intensity of her situation, the satisfaction of feeling Pound’s colthood massaging her insides and her body hugging it in kind.

“T-That’s how I f-felt when I got the...b-big tingles!” Flurry said, her own motions with her magic increasing, feeling her own body tensing up, knowing it’d be not long until she got that intense, lovely feeling again herself.

“S-Sis...I’m...g-gonna...i-in you!” Pound whimpered, his hips jerking back and forth unsteadily, his back legs trembling at the intensity of the pressure growing in his pelvis. The hard throbs from his willy within his sister’s breeding tunnel were getting harder still, and the globs of pre-cum coating his sister’s inmost passage and cervix were growing more and more frequent as his flare swelled up as thick as it could.

“G-go deep! That’s where it burns!” Pumpkin whimpered, her whole body tensed up, her inner muscles’ movements becoming rhythmic and milking...and finally it was all too much as Pound flared and spread her deep inside that much more. Pumpkin squealed out as she came, her body going into its instinctive motions of encouraging the male within her to seed her, her inner muscles contracting rhythmically around her brother’s member from base to swollen flare.

"W-Wow...t-tight h-hugs..." Pound moaned as he felt that kneading feeling within his sister’s passage, that specific sensation calling to his deepest mind, urging him to fulfill his deepest-rooted instinct and to breed her. Pound started trembling, his sensations peaking as his willy’s throbs grew more and more constant. As he felt the tension in his pelvis snap, Pound slammed his hips to get his member as deep as he could, his balls clapping against Pumpkin’s teats, getting Flurry’s attention.

“Y-You’re putting your milk in her right now, aren’t you P-Pound?” Flurry asked, having stopped licking once she felt Pumpkin tense and heard her squeal, along with Pound’s own struggled sounds. As she looked over and saw his low-hanging balls instead pulling up tighter to his body, preparing to spend their virile load, Flurry remembered as she’d felt them tensing like that on her own flank only an hour ago, the memories of him pulsing inside of her, the warmth of his colt milk still in her depths, overwhelming her. As she remembered her pleasure of before, she cried out herself as she spontaneously clamped down on the magic within her, her body tensing up as she herself came again.

“I’m...I-I’m...nyaaah!” Pound stammered out, but was unable to finish his thought, his mind washed by the feeling of his sister’s insides growing tighter and kneading him inside of her, his tip growing thick as he was pressed against that really deep wall thing like he had been with Flurry. His cock flared wide, assuring she took all of the virile ‘colt milk’ that was soon to come from him. He finished with a muffled whinny of pleasure, biting into his sister’s crest, before gripping his sister’s haunches and holding them tightly to his to keep himself hilted.

Flurry felt as wave after wave of wonderful tingles went through her, her entirety shuddering and making her wing’s feathers tickle Pound’s ballsack. Pound tensed as he felt that added stimulation, a loud cry coming from his throat as he held hilted himself deeply into his sister’s passage on instinct, his own wings fully erected above him and twitching. The massive flare of pleasure that exploded in his mind made his hips continue to jerkily thrust into Pumpkin involuntarily, before a few humps in he slowed and stopped again with his flare firmly against his sister's cervix.

Pumpkin gave a cry of her own to join her brother’s as Pound's tip first grew really thick deep inside of her, then very soon after she felt a deep, hot gush after gush of sticky wetness in her tummy, feeling her young stallion's warm ‘milk’ spraying into and pooling in her deepest depths. Her body massaged his pulsing cock of every warm shot of his foal-cream all on its own as she came, bringing it into her deepest parts to coat her womb. She felt utter satisfaction as the burning and itching feelings that were there since earlier that day were swiftly replaced by a thick, satisfying, warm and soothing feeling far within her.

Flurry silently watched this all from below as she still floated in the aftershocks of her own orgasm, the bed behind her coated in her yellowish filly-cum and a little of Pound’s white semen from before. She watched as Pound’s balls ever so slightly swayed and twitched with each jerk of his hips, with her placing a hoof on Pumpkin’s lower belly, seeing and feeling the hardness inside of her belly pulsing softly, as well as a very thick part near her navel stretching her belly even more, and she knew that it must have been his tip being all thick while he squirted.

Flurry remembered when Pound’s tip had gotten very big inside of her and started pulsing like that just before, and all while, he’d put that warm, gooey colt-stuff in her, knowing that that must be the same thing happening to Pumpkin right now; that Pound was putting all of his ‘stuff’ into her.

Both siblings held still as they came together save the occasional twitch, completely tensed now as Pound stayed as deep as possible as he seeded his sister, her body doing its best to drain him dry of everything he had to offer her as her muscles continued milking his ejaculating member.

After a good number of seconds of filling her full, his huge flare giving his cum nowhere to go but up and into her uterus and oviducts, Pound eventually slid off of Pumpkin's back as he dismounted her, his instinctive task complete. His white-coated colthood slid out of her with a loud schlick, a stream of his seed soon following as his softened length swung gently side to side before stopping and dripping their mixed fluids onto the bed.

None of the three spoke for a while, with Pumpkin quickly slumping onto to the bed and rolling onto her back as soon as her sibling dismounted her, her face one of pure satisfaction as her hooves idly traced her lower belly right over the lump of warmth that her brother had left in her. Her position on her back made sure all of that creamy warmth stayed as deep within her as possible, in her womb where it was needed, with Pumpkin instinctively wanting to make sure this breeding was successful without even knowing it. She felt that the burning-itchy sensation from earlier was gone now, soothed by what her brother had put in her apparently.

“W-What was...” Pumpkin stammered, meanwhile reaching a hoof down to her still-spread marehood and coming back up with some thick, off-white, gooey stuff that stuck fast to it; “...i-is this that milky stuff Flurry and you were talking about?”

“Yeah, those really good squeezy feelings in your lower tummy, and the super-good tingles? I got those when Pound put his milk in me too!” Flurry said, smiling softly at the memories, “Did his milk help your burning?” After watching Pound filling up his sister with his colt-stuff, Flurry found her own belly starting to get that ‘unhappy’ feeling again, her small marehood starting to ooze its clear, slippery fluid once more.

As Pound looked at Flurry's ass, he noticed once more that her rump was well rounded, as being a royal gave her a diet full of healthy foods, and nestled between those chubby flanks was a swollen, glistening, deep-pink labia, its bottom portion gently curving upwards, that area hiding the little pink pearl within that occasionally peaked out even still. “Hey, uh, Pound? You think we could do that mommy-daddy game again? I think my tummy wants more of your pee-pee’s milky stuff...” Flurry asked, still feeling the heaviness that Pound had planted deep within her earlier, but her body seemingly wanting more.

“Y-yeah, the burning thing...it’s...it’s gone now?” Pumpkin asked more than stated, somewhat surprised that that discomfort was now completely gone, replaced instead with that soothing, filling feeling of what her brother had put in her. “Wow bro, your colt-stuff is awesome!”

Pound simply gave a small, shy grin to his sister, before turning focus to Flurry. “Um...Flurry? Maybe soon...I need a break.” he said, his willy still feeling a bit sensitive now after his second ejaculation in only a couple hours, while being so young at that. Flurry nodded, before laying on her back and rubbing her labia again, trying to ease that growing burning feeling within her.

After a short break, watching his sister rubbing her slit and playing with his...stuff that oozed out of her, and Flurry rubbing her own marehood, while he rubbed his own colthood, he was soon hard once more. Flurry, however, found her rubbing only made the itching feeling worse, despite only wanting to rub herself more...and more...

“Pound, I’m ready...can we do it like we did before, with you on top of me and me on my back? That was...fun...” Flurry asked, a certain subconscious desperation in her tone.

“Y-Yeah, I’m good to go...my willy’s hard again at least.” Pound said, before climbing up upon seeing her laying on her back with her croup on the bed’s edge in an instant, her tail hanging over the edge and her slit on full display to him.

Pumpkin, upon hearing this and seeing her brother climbing up over Flurry again, felt her own desires for her brother’s colthood to be within her return; that itchy-burning sensation started again, if less intense than before. “B-but I still need him! It’s starting to burn again...what if it gets really bad again like it was!?” Pumpkin asked, worrying she’d feel as awful as she had earlier.

After some more back and forth between the two over which filly he’d be putting his colthood in again, Pound put his own two Bits in. “Well, is there some way I could make you both feel good at once?”

As Pound said that, it seemingly triggered another memory for Flurry. “Wait...yeah! After Mommy and Daddy did the grown-up hug, Daddy kind-of rubbed his willy over Mommy’s mare parts before he put it inside her again, then between her teats, and then rubbed it all over after her filly parts and belly...though I remember he was wearing this funny balloon thingy to keep his colt-milk in. Maybe...maybe you could do that to both of ours!”
