A Shine Cums in the Heart

The door swung open on silent hinges.

Slipping through as soon as it was open far enough and making sure to quietly close it behind him, Shining Armor let out the breath he had been holding. Glancing around the familiar room, his eyes landed on the object of his desire. In a corner of the crystalline room, on a pink bed of hearts and snowflakes lay a gently snoozing form, the pink coated filly laying on her stomach with her legs sprawled out in every direction. Taking gentle steps toward his daughter, Shining Armor smiled at the sight of her slumbering form.

A few months ago, he had been sitting by Flurry’s bedside, long after she had fallen asleep to the sound of his voice as he read her a bedtime story about some detective filly. Lost in thought, his eyes began to wander. As his gaze landed on his daughter’s sleeping form, his thoughts had turned to Cadence. Though at first his thoughts were innocent, appreciating her room-warming laugh and beautiful eyes, his mind wandered to the same place it always ended up when thinking of his wife; her crotch warming innuendo and incredibly hot ass. As he vividly remembered the deliberate show his mischievous wife had given him before she left to the griffon empire a week ago, he subconsciously mirrored the appraising look he had given his wife’s wobbly plot, eyes tracing over the lingering curves of baby fat on his daughters backside as his mind was lost in the memory of those same curves being flaunted at him by Cadence. The parallel was broken as he reached the moment where Cadence had lifted her tail to the side, giving him an unabashed view of everything she had to offer. Back in the real world, Flurry’s tail lay limp down the cleft in her cheeks, obscuring her privates beneath.

Blinking, Shining realized that he was staring at his daughter’s ass with a raging erection and a dreamy look on his face.

Heart pounding, his eyes shot to the door. Breathing a sigh of relief at the firmly shut and always locked door, he turned his attention to the shaft between his legs. While he was normally proud of his tool, being just above average width, but significantly longer than most stallions, it wasn’t an advantage to him now. There was no way he could leave his daughter’s room with his boner swinging free, and he knew from experience that it wasn’t going to go down on its own. Heart still pounding, he knew he was in a pickle.

Glancing over at his daughter’s slumbering form, he remembered what had trapped him like this in the first place. Unbidden, the image of his wife’s ass flashed before his mind’s eye, his dick responding by slapping against his stomach with a far too loud smack.

Jumping slightly, he watched his daughter’s sleeping form, looking for any sign of stirring, but she slumbered on, her reputation of being the heaviest sleeper in the castle maintained.

From experience, he knew that almost nothing would wake the filly, though he still cautiously approached the heart-adorned bed, his own heart pounding at what he planned to do.

Glancing around the room, he lamented the lack of any kind of privacy, the open floor plan not offering any sort of concealment. Cursing his paranoid security tendencies, he looked back down at his throbbing black shaft, trying to think of an alternate way of getting out of this situation, but there just wasn’t one.

He was going to have to masturbate in his daughter’s room.

Facing away from the bed, putting his body between Flurry and his long shaft as best he could, he timidly lit his horn and got to work. Gently grasping his shaft in a tingling pink field, he slowly began to work his magic up and down the turgid length, paying special attention to the area just beneath his flare. Splitting his field to massage his hefty balls, he tried to bring back memories of his wife’s supple behind. Try as he might though, his thoughts kept drifting to the foal behind him.

This wouldn’t be the first time he masturbated to a foal, though he hadn’t been much older than a colt himself at the time. As a preteen just entering puberty, many a night had been spent peeking into his little sister’s room, his trembling magic holding her tail out of the way as he quietly stroked himself into a wad of napkins. Even now, his little sister’s cute little plot occasionally popped into his head when he was horny, the memory just as sharp as the view by the light of the moon had been.

This was different though, he had to remind himself, still gently stroking his dick in long strokes. This was his daughter, and he wasn’t a horny adolescent that didn’t know any better. He was a responsible adult that was currently caught up in an unfortunate circumstance. He mature, and resolute, and was definitely not looking over his shoulder at his daughter’s wide cheeks as he rolled his balls around in their sack. Blinking, he gave up pretending.

His daughter was hot, only in the way that somepony that had spent their formulative years staring at his baby sister’s cute butt would know. Flurry was a bit pudgy, but there was the muscle of a hyperactive toddler hidden beneath the thick layer, giving it a good bounce as she tumbled around the room in play. And, given that she was the daughter of the Alicorn of Love, all the padding was in all the right places. It also didn’t help that Flurry hadn’t yet developed a sense of modesty, her tail flopping about wherever was comfortable while she played instead of being held where it would cover anything. Now though, it was in the way.

Turning back around, still massaging his package beneath him, he gently used his telekinesis to lift the immaculately groomed curtain of hair.

His length throbbed as he saw it. Nestled between her well-rounded cheeks lay the cutest, tightest looking ring he’d ever seen. Little more than a bump beneath her dock with the smallest dimple in the middle, something clicked in his head. From that very moment, it became his life goal to find a way to fuck his daughter’s impossibly tight ponut.

As Shining looked down on his precious daughter, he thought back on the journey that had brought him here.

It had taken him two nights of simply jerking off to the sight of his goal to work up the courage to actually do something about it. Waiting patiently for Flurry to go to sleep, singing her every lullaby he knew, it was several hours before he worked up the courage to act. Finally assured that she was really asleep, he had gently pulled her tail to the side and with only a moment’s hesitation had carefully dove in. Lapping slowly across her protruding hole for a few minutes, mindful to not wake her, he began to work the tip of his tongue against the very center. Poking and prodding, her muscle slowly relaxed until he could just barely slip the tip of his tongue in. Glancing down his snout, he was disappointed at the sight of the tight ring straining around just the thinnest part of his tongue. Not giving up, he continued to work her hole well into the night. And the next night. And the night after that.

Pulling out the bottle of lubricant he had tucked away, Shining popped the cap, jumping at the sound that seemed to echo around the room. Breathing deeply, he tried to calm his nerves. He had been here night after night for months now, but it felt different somehow. After all, today was the day.

Upon Cadences return, he had carefully worked out a schedule where she got to take care of Flurry in the mornings while he stayed up to put her to bed. While he had to pretend to be disappointed that it meant less “late night fun” with Cadence, it did mean that he got to work on loosening Flurry’s tight tailhole every night.

And, as the days passed, that work was beginning to pay off. Each night, slightly more of Shining’s tongue would fit within his infant daughter’s ass, the dimple in the center of her protruding ring growing more pronounced with every session.

Lighting his horn, Shining gently lifted Flurry’s tail out of the way. He dropped from his sheath at the sight of what months of work had done in preparation. She was ready.

After just over a month of nightly worship, something new happened. For the second night in a row, he was able to cram the entire length of his tongue into the crushing confines of Flurry’s rectum, her straining ring wrapped snugly around the base of his tongue as he squirmed the tip into the entrance to her colon. Stroking himself with his magic as he attempted to shove his tongue even a millimeter deeper, he heard a light groan. Freezing at the first sound his daughter had made during one of their nightly sessions, Shining tensed as he felt her insides clench around the intruder in her butt. Holding himself perfectly still, he waited with bated breath as she clenched again and again, the spasms slowly tapering off as Flurry let out a sigh.

He held himself perfectly still, all too aware of the compromising position he found himself in, his tongue buried to the hilt in his infant daughter’s ass, lips wrapped around her ring and erection throbbing incriminatingly beneath him. After a few minutes, he finally allowed himself to think again. It only took a moment of thought to realize what had just happened. Flurry had just experienced her first orgasm, cumming from the sensation of her dad’s tongue buried in her ass while she slept.

Carefully withdrawing his tongue from the depths of her rectum, Shining looked at Flurry’s pink slit. It was visibly wet, and not just from the saliva covering his daughter’s backside. A slight motion drew his attention upward, his eyes locking onto the slight gape of her stretched ring. After a moment, the pink interior was hidden from view as her tailhole puckered in a wink. Entranced by the sight, Shining simply watched as his daughter anally winked at him again and again, each wink taking slightly longer and revealing less of her insides each time.

The heady aroma of his daughters first orgasm combined with the knowledge that he caused it was all it took to bring him over the brink of orgasm himself. He couldn’t tear his eyes away from the incredible sight in front of him as his throbbing length jumped, slapping into his belly as his balls churned out load after load. The first two shots missed completely, spattering on the wall behind the bed. The third string made direct contact though, splattering over Flurry’s backside. It was the hottest thing he had ever seen.

Cleanup had been more difficult after blowing his load across her cheeks, but the temptation of licking it off had proven too great, and he found himself “accidentally” blowing his load over her more and more frequently. He had also found that his goals had changed slightly after that night with the addition of bringing Flurry to orgasm every night. It wasn’t long before he encountered his first problem. In short order, Flurry’s tight hole had loosened to the point where it accepted his tongue with ease, the width of his dexterous muscle no longer stretching her out. He had placed his tip against her ring to gauge how far he still needed to go, and the answer was immediately clear; it didn’t even come close to fitting yet.

A naughty idea had him continuing to press his cock head against her butt, stroking his length with a hoof as he rolled his heavy balls around in their pouch with his magic.

With a slight grunt, his tip flared, wedging against Flurries plump rump cheeks as he came. The tight seal of his protruding urethra against the ring of her ponut meant that the deluge of cum had nowhere to go but in. Spurt after spurt of cum flooded her insides in waves, quickly filling her rectum and spilling into her colon to fill that too.

Finally coming down from his high, Shining stepped back to watch as a small dribble of cum escaped, rolling down her undeveloped slit to land on the bed. As another dollop of cum threatened to escape, Flurry’s hole clenched, puckering tightly in a subconscious attempt to hold everything in.

While Shining thought that the attempt was adorable (and incredibly hot) he quickly got to work lapping up what had leaked out before wrapping his lips around her ponut and plunging his tongue into her depths to clean the cum out.

While fun, the exercise hadn’t solved the problem. He needed to find some way to continue to stretch her out.

His precious daughter’s ponut was nothing like it had been when he had first started. Gone was the tiny bump with the smaller dimple in the middle, replaced by a heavily wrinkled ring just beneath her tail. Thanks to his careful progress and her alicorn physiology, it still gripped as tight as it ever had, though now it was a lot more… accommodating.

Buying a dildo had been embarrassing, but the shop owner had simply chucked and recommended his wife’s favorite lube. Sneaking it in and out of his daughter’s room had proven a different challenge. After contemplating a wide range of options, he had settled for the option he was least comfortable with, though it had the highest chance of success.

Making sure that Cadence was fully occupied with Flurry, he excused himself to the bathroom. Taking the lid off of the toilet tank, he pulled out a plastic bag containing the dildo and a small bottle of lube. Popping the cap, he carefully squirted a small dollop of lube on the dildo, smearing it around until it covered the entire surface. Gritting his teeth, he brought the dildo up to his own back door, though his trepidation was quelled as it slipped in without any hassle. Carefully shoving it deep enough that it was guaranteed to not peek out, he stopped as the tip pressed against what he guessed to be the entrance to his colon. Wiping off the excess lube, he walked out of the bathroom as nonchalantly as he could manage, though one of the castle maids had to keep herself from staring as the prince trotted by with his tail held high, his balls on full display.

Getting Flurry to bed had been an interesting experience. Twice he had caught himself dropping from his sheath as the awkward object inside him rubbed against his prostate, though fortunately both times were while nopony was watching. Once Flurry was finally asleep though, he got to work.

Gazing lovingly at his pride and joy, he quickly dipped his head and, first nuzzling her tail out of the way, wriggled the length of his tongue into her accepting ring. Once he had filled the entirety of her rectum with his most dexterous muscle, he left it buried there, gently probing the entrance to her colon with the tip of his tongue as he simply enjoyed having his cheeks nestled between hers.

Closing his eyes, he focused on swirling his tongue around as deep within her as he could, exploring every inch of her rectum as he hummed in contentment. Pressing his face even deeper between her cheeks, he used the strong muscles of his lips to knead her tightly stretched ring. Stopping his kneading, he gripped her ponut between his lips and his tongue and tugged on it gently. Rewarded with a gentle tap on his chin as Flurry winked for the first time tonight, Shining couldn’t help but smile.

Shifting slightly, Shining felt the odd sensation in his own ass and remembered tonight’s goal. Reluctantly withdrawing his tongue from his daughter’s ass, he watched as it hung open for a few moments, the gentle illumination from the night light not giving him much of a view inside. With a clench, what view there was disappeared, leaving him staring at her gently flexing ring.

Blinking, he grit his teeth at what was coming next. Lighting his horn, he felt his way into his own rectum, shuddering at the tingling sensation as he gripped the dildo and pulled it out in one smooth movement. The dildo itself was bright pink, matching Cadence’s coat color a little too closely to be a coincidence. About half again as long as his tongue, it was made of a series of swells that slowly grew larger over the length of the dildo, like anal beads without the gaps. Sticking his tongue out and staring cross-eyed down his muzzle, he confirmed what he had estimated in the shop, the second swell being just barely narrower than his tongue. Upon realizing he was holding the thing that had just been in his ass up next to his tongue, he scrunched his face in disgust, missing the irony as his saliva string still hung from his lip to his daughter’s ass.

Shaking his head, he lined the dildo up with its target, the generous coating of lube from his own ass dripping on his daughter’s flexing ponut. Gently pressing the first bump in, Flurry’s ring slid smoothly over the widest part. Pressing deeper, her muscled ring strained slightly as it slid over the second bump, resisting for a moment at the thickest part before pulling the dildo in deeper as it narrowed. Pulling the second bump out and shoving it in a few times until it was just as unhindered as the first bump had been, Shining’s cock jumped as Flurry winked again, her small, untouched slit glimmering in the dim light.

Deciding she was as ready as she would ever be, Shining began to press the third bump into his daughter. Quickly reaching the size of the second bump, Shining began twisting the dildo, gently rocking it back and forth as he slowly pressed it deeper. Straining, Flurry’s tailhole slowly stretched further than it ever had before, her ponut no more than a thin ring wrapped tightly around the dildo. With a final twist, the third bump slipped in, Shining biting his lip as his daughter softly grunted in orgasm. Watching her tiny clit winking as her tailhole strained against the dildo, milking it for all it was worth, Shining magically grasped his own trembling length. A few short pumps were all it took to send him over the edge, joining Flurry in orgasm.

As they both calmed down, Flurry’s ass relaxed enough that Shining was able to pull the dildo from her without much effort, though the sight of her gaped hole was enough to get hard again almost instantly. Grunting softly, he shoved the dildo back in his own butt before he forgot about it. Rewarding himself by leaning down and slipping his tongue into Flurry’s loose ass, he licked all the mango flavored lube out so as not to leave a trace, though as he leaned back to admire his work, he failed to realize that he was staring at the most incriminating evidence of his nightly activities.

Looking down at his throbbing erection, he panicked slightly. Cadence had promised him anal tonight, something he would never turn down, and he knew that if he jerked it to Flurry a second time, he wouldn’t be able to get it back up tonight. Glancing back at Flurry’s still gaping hole, he seriously contemplated feigning sick, though if he did that, he would not only miss out on railing his wife’s ass, he probably wouldn’t be allowed near his daughter until he was ‘better’.

The decision was easy, though he needed some way to hide his erection until he got there.

Draping a spare blanket over himself like a cloak, he darted down the hall to their room without incident, though he had to endure Cadence’s giggling as he revealed his rock hard erection.

As their hips met repeatedly, his prostate getting mashed served as a reminder that he had forgotten to remove the dildo. Between that and the hair trigger he had left himself on leaving Flurry’s room, it didn’t take him long to cum, though fortunately Cadence took it as a complement. That didn’t stop her from using his horn as a dildo to get herself off though.

Leaning forward, he pressed his tongue against that perfect hole, feeling it tremble in what felt to him like recognition as he took a deep lick.

Another week passed, Shining working every night on his daughter’s increasingly elastic ponut. Staring into the distance at breakfast, he contemplated when would be a good time to get a new dildo, the old one slipping in and out of her ass with ease now.

Cadence, who was sitting across the table looking incredibly hot with a set of half-moon reading glasses, glanced up from the paperwork she was looking over with a concerned expression. Opening her mouth to ask a question, she was interrupted by Flurry loudly clearing her throat in a way that was a little too reminiscent of the minister of commerce.

It worked though, both parents looking over just in time for her to spin around, drop her chest to the ground and hike her tail.

Protruding from her tightly stretched ponut was the bottom half of one of her foal sized bowling pin toys.

Cadence screamed, immediately rushing over and scooping up Flurry in her arms before grabbing Shining with her magic, dragging both of them at breakneck speed to the castle infirmary. Flurry giggled merrily, enjoying the ride immensely. Shining enjoyed the trip a little less, his enjoyment declining every time he was slammed into a wall as they turned a corner.

Nearly a half hour after the doors to the infirmary had been blown of their hinges, the doctors had managed to calm Cadence down enough to allow them to extract the bowling pin and a rubber ball that had been shoved in first from Flurry’s rectum. The procedure itself was simple, the bowling pin only being slightly too large for Flurry to push out normally.

With the filly happily snoozing in Cadence’s embrace, the doctor explained that it was normal among curious young foals to stick things where they weren’t supposed to. Normally the things were a little smaller and didn’t fit quite as well but it was entirely plausible that Flurry had been doing this for some time now. Combined with the fact that she was the only known example of a born Alicorn, the ‘unnatural capacity’ might be a side effect of that. Cadence and Shining could both attest that the older pink Alicorn was certainly stretchier back there than normal.

Then came the question of what to do about it.

Cadence’s first idea of putting her back in diapers was vetoed by Flurry who disintegrated the offending object five minutes after Cadence put it on.

Cadence’s second idea involved magically resizing all the filly’s toys so that they wouldn’t fit anymore, but that too was vetoed after she simply found other things to stick in her butt, things that were decidedly less safe.

Safety was the deciding factor for the final decision, even though Cadence wasn’t the happiest with it. Shining reasoned that their daughter was stubborn (and magical) enough to get what she wanted regardless of what they did, and considering that what she wanted was something in her butt, the best way to ensure her safety would be to put something safe in there instead of whatever new object she managed to find that might be dangerous.

With a sigh, Cadence admitted that she just wasn’t sure. While he was probably right, she didn’t want to give up just yet. Rather than giving in, maybe there was something else they could try first. Oblivious to her parent’s conundrum, Flurry wandered by, and a quick check revealed that in the five minutes they’d been talking she’d managed to lodge her pacifier deep enough in her rectum that Shining had to feel around all the way to the entrance of her colon to find it. Pulling it from her clenching hole with a lewd pop, it was decided.

While they’d still continue to investigate alternatives, for now it was best to do what they could to keep their daughter safe.

It felt weird to walk into the sex shop with his wife and daughter in tow, but after explaining the extenuating circumstances behind their decision to buy the infant princess a butt plug, the only thing left to do was pick a size. The shop owner helpfully offered a back room and a set of assorted sizes to test with, though he stanchly refused to do the actual testing. Taking one glance at Cadence’s grimace, Shining volunteered to do it since it was his idea after all.

Alone in the back room with a box full of butt plugs and a burbling Flurry, it took every ounce of his willpower to hold back a boner. Due to his familiarity with the hole he was trying to plug, it was tempting to go ahead and simply pick the size that he knew would fit perfectly, however doing so might be a bit suspicious.

Picking up the smallest plug, he placed his daughter in his lap. Coating the plug in a light layer of lube, he wasn’t the least bit surprised to see Flurry’s tailhole simply swallow the thing whole. Pressing it deeper anyway, he worked it around the bend into her colon, much to her delight. Leaving it there for the moment, he took the next size up and, after lubing it, it too disappeared into his daughter’s depths. Picking up the third size up, her stretchy ring still barely gave anything more than token resistance as the plug was swallowed up. Working the trio of plugs as deep as they would go, he watched as Flurry’s clit winked out with a dribble of fluid. The fourth plug took a bit of effort to work the flared base past her ring, but it too slipped inside before finding a spot just at the edge of her colon. The base of the fifth plug stretched her ring to it’s limit, Flurry softly crying out in pleasure as she winked again, fluid starting to flow freely from her.

After assuring a worried Cadence that the cold lube probably just shocked her, he was left alone with a mostly stuffed filly and a significantly emptier box of plugs. Casting a sound dampening spell, he picked up the sixth size, this one a step above the toy that he’d been using at night. Licking his lips, he gently worked it in, wiggling it back and forth to stretch out her ring, earning a somewhat loud moan from the filly. As her ponut worked it’s way over the thickest part, she came, a small spray of juices squirting onto his chest. Holding back his erection was proving near impossible, the view of her tiny hole squeezing against the toy, pulling it in with the slope to bump against the ones already inside of her too much to take.

Despite his best efforts, his length slid out of his sheath, springing to full hardness in mere moments. Flurry, now presented with a new and interesting thing right in front of her face took the opportunity to investigate in the traditional way for a foal her age.

With her mouth.

Holding herself up with her wings, she grabbed his member with her front legs and started dutifully nomming on the tip, drool dripping down his length as she tried to determine the strange object’s purpose through taste alone. Shining let out a groan, his mind caught between terror of the door opening and the feeling of his daughter discovering that the hole at the tip released salty stuff, her favorite. Desperate to get her to stop lapping at his urethra before he powerwashed the back of her throat, he tried to distract her with her butt. Grabbing the plug, he pulled it out of her ass in one smooth motion, a loud pop resonating throughout the room. The gambit worked though, distracting her enough that she dropped his dick entirely. Entranced, she stared back at her own butt as plug after plug was pulled from her gaping depths, the tingle of her dad’s magic stimulating her with each plug, though the tiny one deep within her stopped touching the walls long before it got to the entrance.

He was only allowed a moment to admire the view of his daughter’s insides before she clenched, her rectum closing up a split second before her ponut, though the ring didn’t manage to fully close yet, hanging just slightly open.

Tearing his eyes away from the beautiful sight, he glanced up at the door to make sure that he wasn’t dead yet. Not seeing a horrified pink face, he figured he still had a minute. One minute to get rid of his erection before anypony saw.

Fortunately, he had the perfect means sitting in his lap.

Flipping the filly around, he pressed her freshly stretched ponut against his achingly hard flare. Though it did its best to wrap around his tip, there was still a ways to go before a filly as tiny as her could accommodate a dick as large as his.

It would have to do though.

Lighting his horn, he stroked his shaft quickly, extending his reach down to play with his heavy balls. Flurry did her best to help, wiggling her hips to grind her hole against his tip, though it was most likely borne of a desire to have something in her now empty butt. Regardless of intent, it was only a matter of a couple of minutes before his balls tensed, a thick load working his way up his length to spatter against the walls of her rectum. She groaned happily, cumming again as his load flooded her insides with hot, sticky seed.

Father and daughter panted with exertion, Shining’s last weak spurts packing themselves in Flurry’s overfilled ass when there was a knock at the door. He flinched, his eyes widening as he shakily spouted some vague reassurance. Realizing the sound barrier was still up, he took a deep breath, dispelled it, and gave a much firmer reassurance that he was almost done. Putting the barrier back up, he pulled Flurry off the tip of his dick, quickly swapping her tailhole to his mouth before she spilled too much. He still found the taste of his own cum a little weird, but he’d drank enough of it out of Flurry’s ass by now that he was used to it.

Quickly sucking as much out of her rectum as he could, which gave her a big giggling fit, he scraped her juices off the both of them with his magic and drank that too. With the evidence hidden and his erection finally retreating, he cleaned the lube off the butt plugs, noting that the one that actually fit was apparently a size G before putting them away.

Doing a quick once over of the room to make sure he didn’t miss anything, he dispelled the sound bubble and trotted out of the room, looking suitably uncomfortable. Passing a sleepy Flurry to his wife, he told Cadence to take Flurry and head to the castle so that the young princess wouldn’t have to spend any more time surrounded by dildos, to which she readily agreed.

Picking a simple looking steel G plug, he also picked out a set of anal beads that looked like they started just slightly smaller and worked their way up to almost the size of the narrow part of his shaft. Checking out with both of them, he made his way to the castle, doing his best to avoid questions. Using a side entrance, he took a roundabout route to the room that allowed him to drop off the beads in the toilet tank with the old dildo.

Pulling his tongue out of Flurry’s loosened hole, he brought the lube over and cast a gentle warming spell on the bottle before dribbling the thick fluid into the slight gape at the center.

After learning a visual misdirection spell to make the shiny plug near unnoticeable, he was put on plug duty, which suited him just fine. Every night he continued to work on spreading her ass with the beads and every time the plug started to get loose, he was able to surreptitiously swap it for a larger one.

It was a mild surprise when he pulled the plug out one day to find that Flurry had removed it, stuffed her ass with random toys and then put it back in to hide what she’d done. Pulling all the toys out he decided to ‘reward’ her efforts by graduating to the next plug size early, the stretch being just enough to make her cum. She was later upset to find out that the plug was big enough that her magic wasn’t strong enough to overpower her sphincter.

The back and forth shenanigans of father and daughter trying to outpace each other did wonders to speed up the process of stretching her entrance out. To Shining’s dismay though, the plugs were doing nothing to stretch her deeper depths, and while the idea of getting his dick inside her at all was the goal, he desperately wanted his first time with her to be perfect and nothing short of balls deep would do.

With that in mind, he made another trip to the toy store. The visual misdirection spell proved itself invaluable as the quantity of toys quickly outgrew the toilet tank, now being stored in a nondescript box behind the bathtub. He had a hard time finding it most nights and he knew exactly where it was.

Dumping the rest of the bottle over his own dick, he ensured it was fully coated. It was going to be a tight fit after all.

Pulling an average sized horsecock dildo from his ass with a pop and a groan, his infallible toy transport solution was starting to shape him as well, his deeper reaches getting a stretch as his tendency towards caution saw him shoving the larger and larger toys deep into his colon to ensure they would stay put. It still wasn’t as drastic as the changes to Flurry though. After he had transitioned from bead shaped toys to a collection of progressively larger rubber horsecock dildos, he’d made excellent progress on her deeper reaches. Tonight would be the last night with the current size and then he’d have caught up to her current plug.

Withdrawing his tongue from his daughter’s ass, he lined the length of rubber up and eased it inside. Her ring hardly noticed its passing, the same holding true for her rectum, though that was to be expected. Her current plug was massive compared to her small stature, her stomach noticeably rounding when it was seated in her. He knew that the plug itself completely filled her rectum, the tip of it resting at the entrance to the sigmoid bend of her colon. It was only by some miracle that Cadence had left the entire situation up to him, preferring to dote on Flurry in every other aspect, or she might have noticed that the massive object in her precocious filly was starting to get big enough to comfortably fill a normal mare.

Distracted as he was with his thoughts, he only noticed how deep he was going when Flurry’s ring snapped shut behind the intruding object. Cursing his above average length once again, he continued pushing deeper anyway, though his mental complaints died out as he focused on catching his daughter’s second orgasm of the night in his mouth.

As soon as she settled again, he suffered a moment of clarity, the sight of his precious little filly sleeping peacefully seeming so innocent even though he knew that a respectably sized dildo rested somewhere in her colon.

With no warning, he blew his load all over her back, spoiling the innocent picture a little. Sufficiently reminded of why he was doing this, he couldn’t help but grin as he cleaned up his mess and extracted the rubber mass from his daughter’s clenching hole.

He wouldn’t have to wait much longer.

He’d come so far, done so much, and it was about to pay off.

Pressing the head of his dick underneath her tiny dock, the sheer girth of his member compared to his daughter’s soft ass forced her cheeks apart. Resting with his tip nestled against her trembling hole for a moment, he took a deep breath to steel himself.

Agonizingly slowly, his tip spread her quivering rosebud. Both of them let out a quiet sigh as he popped in, the incredible heat and exquisite tightness almost driving him to orgasm right then and there. Gritting his teeth and clenching his eyes shut, he gave them both a moment to adjust.

Shifting his hips, she let out a grunt as he worked himself deeper with a smooth thrust. He let out a grunt of his own as his head left her comparatively roomy rectum and squeezed deeper, straightening out the bend as it went. Before he knew it, his medial ring bumped against the straining ring of her ponut. Holding back for a moment, he gave a few shallow thrusts to help loosen her hole for the imposing black ring.

Figuring that she was as prepared as she could be, and with his endurance growing thinner every thrust, he braced himself, positioning his front hooves in front of her shoulders to brace her as well. Pushing forward, his medial ring bumped into her with a thump, the dark pink band of flesh drawn smooth as it slowly but surely gave way to the intruder.

With an audible smack, her well trained muscle snapped tight behind the bump of his ring. The warm tube of flesh wrapped snugly around his dick quivered as she came for the first time that night. By some miracle, he didn’t join her, though his balls tensed in warning. Taking deep breaths, he managed to inch himself back from the brink of blowing early. He’d worked so hard for this night that he refused to allow himself to ruin it for the both of them by cumming too soon.

Finally feeling ready to continue, Flurry having long since settled from her last orgasm, he leaned in and nuzzled into her neck. With a slow thrust, he gently eased himself deeper, Flurry moaning softly as his flared head drug against her inner walls, stretching them wide to accommodate its passage.

It felt like it took an eternity to fully seat his length within her, his hips near-soundlessly pressing against her plush rear as his balls settled against her untouched fillyhood. Taking a deep breath to steady himself, he felt Flurry tense against him again, her body shuddering as her tiny clit tapped against his heavy balls, a trickle of filly cum spattering against the leathery black sack. Spent for the moment, she relaxed completely.

With the death grip that had surrounded his member loosened, he found himself free to try thrusting without fear of prematurely cumming in her. Sweat dripping from his brow, he pulled himself from her depths. Even though her body had relaxed, it still clung to his length as if it never wanted to let go, only relinquishing its grasp with a loud, slurpy pop. Immediately switching directions, he drove his length into her with a single smooth thrust, his hips slapping against her plush rump with a clap. With another pop and a clap, he repeated the deep thrust into his daughter’s hot tunnel, his balls smacking against her winking clit causing them both to moan.

Shining’s peak was approaching again and this time there was no holding back. Hilting himself as deep as he could, he let loose, his twice denied balls aching gently, pulling tight to his crotch as they geared up to deliver their payload.

And deliver they did. With an audible sound, his thick cum rushed through his tubes, erupting from the tip of his dick buried deep within her. With his wide flare sealing tightly against her walls, the only place for the cum to go was deeper into the tiny princess. Each powerful clench of his balls sent more virile cum into her already packed bowels, her stomach pressing against the bed as her dad’s cum coated and filled every nook and cranny within her. The sensation of stretching deeper inside her than ever before was more than enough to drive the young alicorn to her third orgasm of the night, her insides seemingly milking his dick for all the seed it could give her as she did her best to return the favor by bathing his balls in her liquid arousal.

Even the most powerful orgasm he’d ever experienced had to end eventually though, each jet of cum getting smaller and weaker. It was just enough though, his daughter coughing up a wad of his cum as the last dribble exited his tip.

With a gasp, Flurry’s eyes shot open, her young mind quickly taking stock of the situation. Finding herself encompassed inside and out by her dad, she relaxed, nuzzling into him.

"Wuv you, dada.”
