Shining Sloshing Fate, Flash Rise to Power

Shining Armour was having a very tiring day and only seemed to get worse for how his wife was acting today. Princess Cadance was out of the castle with nearly all of the castle staff on vacation today, Shining forced to stay home in the Crystal Empire as his wife and child went on vacation. Shining unfortunately missed one to many days of Flurry’s school talent shows. Shining, unable to meet the scheduled special fundraiser that his daughter was picked to be the face of and help the school.

Shining is forced to clean the rooms around the castle that the family use mostly, such as bedrooms, bathroom, and dining rooms. Taking care of most of the rooms, Shining only had his daughter's room to clean finally. Nearly done with his punishment, Shining finishes drinking the last of the drink he was given from a maid and gets to straightening up the room. Working as hard and quick as he can, It was nearly lunchtime by the time lunch was rolling around. Shining while using his hoof as his magic was feeling weak and this headache that was creeping up wasn’t helping him at all take care of his daughter's room.

Stumbling over his hooves as he holds himself up against the cabinet for Flurry clothes, Shining brings a hoof to his head to try and smooth his head. “Argh MMph… going to stop by the medical ward if this keeps up…whew…” Not really knowing why he was feeling so bad suddenly, he kept working till collapsing onto a small couch near his daughter's bed, passing out as he promised to stop by the ward soon to check the issue with his head. The entire time, not realizing he was getting just a little smaller as the spiked drink began to take effect over his body and truly sped up when he went to lay down for a short nap on his daughter’s pink bed.

Out of the little princess bedroom, a lone guard, looking suspiciously bulkier than normal, was waiting for the captain to finally succumb to his little surprise~. A golden yellow stallion with a blue mane, gave a maid with instructions to deliver the drink to the captain, making sure that it was a secret gift to be given before the Captain started his last room. Flash Sentry was keeping the hallway empty, making sure that he wouldn’t be disturbed when it was time for his fun with the “Captain” of the guard.

Hearing soft snoring in the room signals that Shining Armour was out like a light for a short time, the potion possibly acting quickly and painlessly. “Heh…Sounds like it’s time for the fun to begin little colt… Time to babysit the “naughty” baby it seems~.” Flash smiling evilly, he checks to make sure the coast was clear before entering the room and locking it behind him. “Well.. well… Little body seems to be out cold. Played too hard and all tuckered out~.”

As Flash looks into the room, a lone colt seems to be napping on the couch.The colt himself looked off and similar to Shining Armour, the potion that was drunk, reducing his size to that of a baby colt, only in size and not age. The large stallion magic being suppressed as well to prevent any complications when being reduced in size from the potion effects.
Flash, wanting to have fun with his colt sized“boss”, begins getting some items ready for Shining, when he wakes up to see his new look. After knowing where all of the items were when needed, Flash gets the first set up ready, dressing the napping colt, wanting him to be ready for the fun time ahead. A pretty princess filly pajamas with his daughters’ diaper placed on to the sleeping colt, with a fresh cup of water for good measure already soaking the fresh clean diaper for the colt to have a soggy diaper when waking up. With everything ready, Flash brought ‘baby’ Shining and placed him into the baby crib nearby.

As Shining wakes up from his ‘improvised’ nap, he brings a hoof to his head, rubbing it gently as he tries stealing himself from the burning of the potions effects. “UUrrgh…my head… Perhaps some water….would… help…?” A much high pitched voice catches Shining attention, as he lowered his hoof, stopping as he looked around the room in front of him, not seeing the stallion behind him yet. The once small room seemed much larger as he looked around, seeing that his little girl room was so different now behind the crib walls he finds himself sitting in. As he got up and walked closer to the crib walls, he didn’t hear his wet diaper jiggling behind as he inspected his daughter's room with fresh eyes’ at this new perspective.
“What in Celestia Twin Suns tits….Am I still dreaming?” The higher pitch Shining asked aloud, as he looked out the gated wall within the baby crib, Shining sat down onto his wet diaper, as he now looked himself over.
Looking down, he sees himself wearing pajamas with happily little pink hearts polka-dot around on a soft blue background, looking further down he could feel the heavy tighten hold around his flanks, knowing he was in a soiled diaper along with the clothes, a wetness clearly being felt as he sat within the filly’s crib. Feeling the soft and soaked padded cushion around his flanks was such a weird feeling, he wasn't sure he liked it at all, but glad at how soft it was and keeping the crib mostly dry when he felt the comforter, knowing his daughter was treated to the best absorbent, form fitting, and soft padding filly diapers money could get for his little angel.
Shining, continuing his lower inspection, felt around the soggy diaper, to make sure he still had his “sword” between his legs. “Well… still got my pride, even if I did wet myself, I guess, so there's that bit of good news, and I'm dressed in Flurry’s clothes.” Just as Shining was about to stand up to find a way out, a rough cough got his attention. His hair stands up on the back of his neck at full attention as he quickly jumps in the air, spinning around as he notices the other pony in the room with him.

“-Cough-“ Flash Sentry standing up walks up to the crib, giving an overbearing presence to the little colt before him. “Well look who we have here~. A ‘naughty colt’ trying to escape nap time and seemed to have made a mess while at it~.” Flash gets ready to begin the fun shortly with his former captain as he looks into the shocked embarrassed face of the little ‘colt’.

“W-What!? Flash! Why are you in my Daughter’s bedroom! I'll have your Ass scrubbing the toilets for a month for trespassing into her room!” Shining already was trying to keep the troublesome guard away from his sister and had him under his watch, keeping him mostly in the non-important sections of the castle. Being in the Royal Family floor was not where he was meant to be at all. Shining, getting red in the face, only angers him further at seeing the guard now in his little Flurry’s room. “I’m gonna be demoting your piss colored hide for this you damned winged chicken! SO wipe that fucking smile off your smug ass face! Or do you want to be adding new training Regina to your punishment as well for how deep shit you're trapped in!?”

Flash, not intimidated by the cursing pint size colt, casually grabs the shrunken stallion turned colt easily, and sits him on the couch nearby, pinning him down as he brings a hoof up to straighten the struggling unicorn in his grip. Pulling the PJ bottoms down, keeping the ‘messy’ diaper on, he times his strikes just right to punish the struggling colt. “Bad little colt. No yelling that potty language at your babysitter! -Smack- Cursing at your ‘angle’ of a babysitter here as he takes care of you while your parents are away. Look what you did to your ‘dippy as well, ‘peeing’ in the crib!’” Flash spanking the colt several times, earning several painful yelps, curses, and pleas to stop as the crying colt begs. The little horn on the wailing unicorn lightening up but, unable to do anything but, pitifully glows, barely a spark to do anything besides showing off how useless it was. “Who's been a ‘bad colt’? Who pissed their diapers and made a big wet mess? Come on now you naught boy! I won’t stop till you say the magic words~!” Flash keeps up the punishment for nearly 5 solid minutes of loud spanking. Listening to the colts cursing and painful yelps

“-Smack- Aaargh! You fucking bastard of a bitch! You! -SMACK- Will be court marshal! -Smack-“ Shining, giving a hard fight during all the spanking he was receiving from the golden yellow stallion. Tears on the edge of his eyes as he tries to fight back, but unable to overpower the pegasus above him, with strength or magic. After what must have been the hundredth slap, Shining finally relents and cries as his threats of retribution, turns to pleas for help before finally doing as he was told, crying as he does so from the painful hold and sore flanks now.
”AAaah! I-I-Im S-Sorry! I’m a B-ba-bad c-colt! I’m sorry! I pissed my fucking Diaper! Please just stop! -sniff-. I Made a Mess in the Diaper Flash! L-let me go….P-please! I was a bad damned colt! I shouldn't have yelled at you!” Shining will was a broken mess, accepting his fate, praying that somepony would save him, or that this nightmare would end. As the spanking stopped, Shining felt the hoof letting him up, himself curling up as he stared into the eyes of his tormentor.

His eyes wet from crying, face slightly red from the crying and frustration at being physically hurt from the pegasus. The Pajamas in s disarray as the pants were tangled up on one leg, his diaper actually torn up some and fell off, removing any wet cushion he did have at the start, the cool water doing little to comfort Shining as it drips down in legs, and the shirt wrinkled up, nearly choking Shining some with how bunched up it was getting around his neck, a hoof escaped the sleeve and causing in to tighten around his throat from the struggles.

“Good little colt, that's what I wanted to hear!” As Flash compliments the scared colt, he walks around the bed, toward his next plan of fun. “NOW! Don’t misbehave and I won’t have to get physical again on those sore flanks of yours.” With keeping the scared colt in his peripheral vision, opens the drawers’, grabbing the items he set up earlier, having them in wing out of sight as he watches the shrunken stallion. Seeing Shining getting out of the ruined clothing, drying himself some with the pajamas, Flash watched his ‘responsibility’ getting undressed from his ‘watch’, knowing it was time for the next outfit. Throwing the hidden clothes to the colt, a scared yelp springs out from the colt as Flash watches him struggle with the unknown items. “Get changed into that dress! We Can't have you running around without the proper outfit!” Flash yells out as he moves to grab a camera that was placed in the room near the exit for emergency Flurry Heart moments. Several were ready for the princess to have if Flurry ever does a heart stopping cuteness to captor forever. One fresh for Flash to keep and another for the princess to ‘enjoy’ without him being seen in it.

As Shining freed himself from the unknown clothing, he noticed it was the pretty blue sun dress for Flurry to wear in royal meetings. “This is a filly dress! I’m No-“ Shining was about to refuse, before a stern stomp form Flash caused him to freeze before finishing his sentence. A stern side look from Flash, wings spread out threateningly, was the only warning he needed to shut his damned mouth and do as he was told. “-Gulp- I-I mean Yes sir! Right away!” Shining drill instruction takes hold for a moment as he throws the frilly blue dress on, not wanting to anger the stallion in the room. Once he got the tight fitting dress on, he noticed a frilly pair of panties were next to him. A quick glance and a nod from the stallion was the only answer needed as a shaky hoof gets them ready to pull them up, his flanks slightly wet still but, dried slightly with the fresh clothes on.
“This is so humiliating….” The distraught unicorn says before a loud -CLICK- rings out as he nearly pulls the panties up fully. Shining head snapping to the camera in Flash hoof, ‘his’ panties nearly up as they bulge up against his little ‘sword’. “Please tell me you’re not doing this to blackmail me…” Shining whines out as he finishes getting dressed in his daughter’s clothes.

Flash only giggled at the question as he got ready for his photo shoot, one for his wife to find and the other as a personal memento for himself to enjoy in the future. “Oh sure. Yeah total blackmail material here. Least of your worries here as we capture the moment!” The next 20 minutes were several random poses of Shining forced to be in. Some questionable, others mostly normal looking beside the fact the captain was colt sized in a filly’s dress now.
Outfits were changed at one point, putting the unicorn into a very pretty blue dress, holding a school bag as if he was about to begin his first new day at the Crystal Emprie’s schools. At one point, water was thrown onto the captain as if he wetted himself, before being dunked fully in water to help ‘clean off’ the mess he made. The photos were all saved in the camera for later printing if Flash wanted to keep them.
“Well that was fun! Saved all our first memories of us playing around! Just like ‘father and daughter’ time would be if I had my own little filly! Thanks for the fun, but I think it’s time we call it a night!” Flash grabbing the colt once more throws him onto the filly’s couch near the crib. Himself feeling himself to start getting an erection for the next part to come. His shaft being counseled for now as he wants a naked humiliated meal now for his cock to enjoy. “You can get that silly dress off, we don’t need it anymore now.” Flash off to the side, sets the camera down for later use as he plans to get rid of the captain and prince of the empire soon, the moment needing to be captured for himself to always remember.

—————————————CW: Cock Vore———————————————-

Shining with his back towards Flash, doesn’t suspect this would be his last night here as he believes he can finally get out of here soon and plans to deal with his subordinate later on. “Urgh….Finally can get out of this mess. Since you are here, can you tell me how to reverse this spell?” Shining pulls off the panties and dress, throwing them to the side as he stands on the bed, turning around to face the stallion in the room. “You must have been the one to plan this so- WOW! OOF…” Shining didn’t get a chance to finish as he was quickly tossed to lay down on his back, and pinned once more by the pegasus. A warm and very hard cock laying on him as flash impressive cock presses deeply into the former large stallion. “Uuuh…W-what are we doing on the couch Flash…” Shining more knowing and fearing the answer of what was about to happen, as the slightly leaking rod drips pre-cum onto him. The large imposing shaft in his face gives a massive masculinate smell that fills Shining nostrils with the musk of the leaking tool.

Flash only smiles evilly as he rubs gently into Shining with his throbbing cock. “What’s the matter, Shiny. Don’t you want to have a roll in the hay with your ‘babysitter’. It’s your choice here though, or I’ll just go ahead and skip the part of us having some lewd fun together. Your pick this time little colt~.” Flash gently rubs his cock as he talks, removing his hoof as he teases the colt below him, letting the tip come just shy of Shining muzzle. Waiting to see if he would pick the fun time or the snack time, even if he didn’t tell him that he was going be cock food very soon anyways.
“What is it going to be Shining?” Giving one more thrust, the tip of his cock booping the stallion size colt on the nose as a makeshift kiss, little pre connecting the two for a short moment before it breaks away on the retreat. The colt looking face scrunching up in disgust at having the throbbing cock touching him while still being pinned down slightly.

Shining knows something was off if he doesn’t agree, but the thought of that being inside him, throws that thought out the window as he rather not risk being split in two while being this small. “N-no thanks. I think I'd rather be big again now please…and put this day behind me…” His voice, still high pitched, sounded even higher as he was afraid of the neck punishment ahead, his flanks still sore from the first encounter.

“Darn…” Flash sounds and looks disappointed, but knows he needs to hurry up with his plan before it gets too late in the day. “Well in that case let’s get you safe and secure then now! After all, it’s not you I want to insert this thick cock into, but a nice pretty mare in ponyville that runs this new school! She has a nice star sparkling flank’s, you couldn’t help but stare at it all day when you see them walk by.” His grin comes back in full force as he slides his cock back, hooves keeping shining pinned as he begins using his wings to help line up to the little rear hooves of his snack.

Shining eyes widened at the mention mare, and was about to retort his anger at the comment before seeing the imposing cock lining up after he declining the anal sex offer. “Don’t yo-! Wow hey! I said NO! Stop it!” Shining begins struggling again as he thinks Flash was just going to force the cock inside him anyways. As he tries to escape the hold, feather wings begin forcing his rear hooves down, his eyes widened in shock as he noticed that instead of taking the dick, it was taking him. Frozen in shock at the sight, he lets the throbbing cock seemingly expand over his hooves slowly, working its way up and clenching hard forcing more of him down. The large cock nearly the size of his shrunken colt sized body, was swallowing his hooves down. ”What….the…FUCK!?”

Flash seeing the stunned look on Shining face was too priceless to pass up. Quickly grabbing the camera with a free hoof, he snaps another picture before giving a deep thrust, sending more of the colt down. “MMph…this is going to be a good night for me it seems.” Keeping his short thrust going, nearly up to the small dick of Shining’s, the widened superior cock begins to take in the inferior cock. “Enjoy your stay inside the tight sack. It will be your last.”

Shining not believing as he watches his flanks begin to slide into the leaking tip, cum squirting out slightly as he watches it take more of him down. His cutie mark passed down the tip, disappearing into the dark yellow cock. The strange sight is horrifying for him to see, and only getting worse as he can feel each clenching taking more of him down. The moist and wet feeling of cum all over his legs. The tight squeezing muscle clamping down and further restricting his movements within the shaft, only small wiggles as he feels his legs. All in a few short minutes as his mind processes the sight, not even hearing Flash taunts or the camera from before capturing the moment of his broken reality of being eaten by a cock.

Shining mind working overtime, finally realized he needed to do something and flee the large imposing stallion in the room with him. His only two free hooves were trying to punch, slap, grab anything to stop his descent.
“Flash! STOP! Let me go! Somepony! HELP!” Shining trying and failing at his slaps gets no reaction and forgoes attacking and tries fleeing with grabbing anything to help him slow his descent and escape. Only a bunch of sheet’s and a pillow being thrown aside doing nothing to stop the creeping shaft clenching him further down. “-Sob- P-PLEASE! NO! Come on! Why are you doing this!?”

Flash only moans at the full feeling of his shaft expanding over the shrunken cock snack, himself not minding the pitifully slaps and punches Shining was trying. The colt sized stallion without his magic, lost most of the strength as well, that would’ve made him a threat. Now being a nice colt size snack, he would only be trouble if he could run out the door, but it was much too late for the future foal batter to try and get help.
“MMph… The Princess was so considerate to keep the family floors empty for us today. Otherwise somepony may have heard us.” Flash looked down with his face blushing red as he tried getting his breathing under control, not realizing how out of breath he was feeling from taking in the unicorn, even better knowing it was his boss. “You may be surprised, but you are only the third pony I had the pleasure of making cock food. They were both some maids that went missing.” Flash leaning down, uses his wings to hold the struggling hooves down to Shining side, as he stares into his panicked face. “Do you know what happened to them? They were melted down and released as a drain clog mess in the bath. Nothing but a thick white mess to be lost in the sewers, with no one to know where they went.”

Flash took great joy watching Shining eyes become pinprick in size, the unicorn filling with dread as he didn’t want to believe what he was hearing, but praying he was joking. The struggle became even more erratic as he tried to free himself from the strong hooves of Flash. Wiggling his hooves to get out of the grip, Shining only stares down as he sees the tip of the cock was only one clench away from being trapped into the shaft. “That’s it little shinny… You’re almost halfway there! Let’s get you tucked away for bed like the good little ‘colt’ you are! HAhaha!” Flash enjoys the moment as see’s Shining thrash harder before he gives one hard thrust, timing it right as he clenches once again. A sickening squished rings out to the horrific unicorn, but pleasuring moan for Flash. With all of Shining hooves secured, he was hopelessly trapped in the throbbing shaft that continues forcing him deeper in.
Splash of pre-cum further lube’s of the coat of the doomed unicorn, a little even squirting into Shining face. The shrunken stallion, disgusted at the taste, spits out to the side, earning a taunting laugh from the pegasus. “What’s wrong Shinny? Don’t like your ‘milk’? You better drink up now, I got plenty more where you will be going. Mmmph…that's the spot. I have a nice full sack of milk for little colt’s to grow big and strong~.” Flash further teases the unicorn, feeling each struggle as he forces more of the stallion down, hooves rubbing the bulge now that he was secured mostly in his leaking shaft.

In the foal maker sack, little rear hooves were finally poking inside after the hard thrust. The slowly expanding sack swayed with each pump of the hips, filling more of the hanging balls with fresh unicorn to churn up into a nice pegasus cum for a lucky mare or a drain to be forgotten about in a steamy shower. As more of the struggling unicorn fills the balls, the more defined each push could be seen. Soon enough, the hips of Shining are forced inside and begin clenching around the struggling unicorn, compacting him into a more defined position to work down. Keeping the cum meal from putting up too much of a struggle, the fetal position was the perfect way to curl up an unruly meal being deposited inside.
Amongst all the soft panting and moaning from the dominating stallion, his own body was kicking up other sounds as well, making lewd sloshing and soft churning noise from his sack as it leaks further cum out into the balls. It’s own special melting cum recipe to melt its unwilling occupant that was being forced inside, some even leaking out to lube up the meal further for easier insertion.

Flash was nearly done sending his cock snack down, himself wanting the last look over the panicked face. While the bed was a princess bed, meant for a small filly, it was perfect to lay down for a single pony such as Flash himself. Moving around, he lays on his back, resting on a soft comfy pillow that was thrown as he gets a good look down his belly with a still thrashing head just shy of being swallowed up. His sack bulging comically with the lower half of the prince trying to push himself out and failing horrible. “This is a nice couch, you really did want the best for your little girl huh? Hehe..” Flash poking Shining on the nose, as he laughs at his scrunched panic face still softly crying as he watches him. “Love the new look for you ‘captain’! Better than all the pretty pink princess dress you were wearing~.” Grabbing the camera once more, he takes another picture of the moment to remember it always, the crying face of the trapped unicorn nearly sent down his shaft.
“Wish I had this much fun with the mares, but this moment right here. I will always remember this and hopefully try to recreate it with future ponies now!” Rubbing the head of the unicorn, he rested his hoof there holding him there for a moment. “Any last words? Or ready to end this?”

Shining, getting his breathing under control, gets one last shakely breath in before trying to shakely beg for release. “F-flash P-p-plea- NO! STo-mmmph!!” Before he could get his last plea out, Flash shoves him in roughly, stopping his begging. The tip of the throbbing cock, moving over his head fully, giving the final view of Flash cocky face being the last sight he would see and the vision goes dark in the moist leaking flesh walls dripping and slathered cum all over him as he was forced deeper down towards the sloshing sack. The trip inside felt much worse now that he was outside the cock itself, and the tightening feeling being swallowed up didn’t help make the trip any more pleasant for the scared stallion in the dark environment. Shining was nearly all the way deposited into the heavy golden sack of Flash, his forehooves nearly free from the constricting tunnel of flesh. Soon though every part of him would be joining his butt though in the cum filling sack.
“MMMFffffph! Hlllp!” Outside Flash could trace ever defined bulge of Shining, watching as the struggling form slowly entered his expanding sloshing balls. Hearing the muffled protest only helping reverberate within his leaking shaft, that slowly returns to a normal size, little cum leaking onto his belly. Moving a hoof to the head, he rubs harshly onto the head of Shining, getting more muffled complaints as he helps push him further down. “Mmmmph! Mmmphhh!” Flash only groans in pleasure as he watches the near completion of taking the once proud prince and trapping him in his personal ‘baby batter maker’.
Head exiting the shaft and now fully inside the balls, Flash sits up and begins rubbing around the now thrashing sack as it begins really struggling with the full colt size stallion inside. “Keep that up Shinny, I’m sure if you keep this up you will escape!” Flash teases him further, knowing that he already had 2 ponies in and they were much more lively then he was currently. “Yeah, keep it up cum slut! Just keep moving around, and slosh that cum all over you. Going to need you to be all cleaned up into a thick mess for later on.” Flash moving back to rest against the couch hoof-rest, rear legs spread out for maximum sloshing movements, begins rubbing fully down with his fore-hooves. The sensual movements of rubbing and feeling all the squirming bulge of his cock snack only heighten his arousal from touching all over his sack. Feeling very tempted to cum as soon as the solid mass was fully melted down, but that would ruin the fun he would have for later. “MMmph..yeah… Life is great. Thanks for the fun little Shinny.”

The next 30 minutes passed by as a pleasuring blur, Flash taunting and rubbing all over his heavy sloshing sack. The cum filling up further and becoming less defined as a bulge of Shining was slowly losing his solid form. Shining himself was having a Tartarus of a time, the musky humid confined sack of flesh unpleasant from the moment he slid inside. A tingling sensation barely noticeable before it became more prominent as time went on. Shining lit up his horn within the tight environment, unable to use any spells to escape besides light up to see for any exit to escape.
Outside a small glow could be seen within the sloshing sack, giving a teasing sight as the sloshing sack was glowing from the weak magic of Shining Armor.
Flash actually enjoying the show as he sees the struggling colt sized prince moving around with the small light show, earning a small smack with a teasing laugh.

“Keep that horn glowing! Never seen anything like this before, perhaps it can be my melting timer for when you finally expire inside!” Flash rubbing harder where he sees the location of the glowing horn. “Hey! You know what would make this even better? How about you make a “Ding” sound,’ when you're done melting! That would be an amazing sight to hear! HA!” Flash taking the struggling within as a no, but enjoying the teasing of dominating the ‘colt’ within his sloshing sack, giving it a smack at his crude joke on the scared little Shining Armour. Flash heavy sack though, actually was having a timer of sorts, being slowly fading into view of a cutie mark of a familiar shield only lightly showing up at the start, very few details being seen, but noticeable enough to know it wasn't there before over the struggling cum sack.

Shining ignoring the taunts, tries to get out still begging and pleading for release, only getting, ‘You will get release when you’re melted into Foal batter’ or ‘Still need to bake in my sack for a little longer, times not up yet’ from the pegasus. Shining literally seeing his lower body slowly melting down as he struggles around in the cum filled sack, once as a small puddle, now filled up to his belly was still rising. Bringing up a rear hoof, he was further disheartened when instead of a normal leg, was now a melting mess of flimsy flesh that broke off painlessly into the cum bath.
The stallion size colt, at first struggling hard as he could, throwing his weight and punch the wall with what force he could muster in the confined cramped sack, before slowing down to rest after no noticeable effect to his captor. Catching his breath in the stale musky air of the churning foal sack, Shining was sitting in the rising cum bath, nearly up to his chest as he sat hunched over. Deciding to look over the damage with what little light he had left from his magical horn, Shining started with his forehooves, seeing that besides being reduced in size to a colt, looked notable shorter than before, and melting off in different part, looking thinner in some spots, while thicker in others.
Pulling up a leg was even worse, as it seemed to be half the length when he woke up in the bed,one of his rear hooves actually falling off when exposed into the open air, causing a small splash to happen as it landed back into the cum bath to continue melting down. Even seeing a chuck of his flesh fall off, feeling no pain was a terrifying sight for the stallion. Though Shining only dry heaves at the sight now, the terror paralyzes him with fear from destroying his body any further, praying to whatever gods or devils would save him from this horrific demise. Moving a hoof up higher, Shining rubs his head around some, feeling the small pride and joy any unicon would take the utmost care for, the magical conduit being the glowing horn. His soft glowing magical horn, Shining, feels around, trying to feel how much of his pride was left, accidentally knocking the weakened horn off, killing the light show within as it splashes into the cum bath as well joining the extra melting bits in the cum stew he was sloshing in. The little glow effect going off from outside as Flash watches it disappears, Flash still feeling some solid forms within though. A taunting sounding ‘DING’ rings out from the pegasus followed by a haunting laugh to the melting stallion within. The once dull looking cutie mark on his heavy sack, nearly in full details and color now as the shrunken stallion within was nearing his completion of meat into liquid seed.

With the soon to be demise of Shining Armour, Flash gets out of bed and stretches, mindful of the heavy swaying sack of his sloshing around filled to the brim with life giving cum. Getting used to the new weight, as he doesn’t plan to lose the precious load just yet. Heads over to a window, planning a trip to Ponyville, wanting to be there by morning when the special mare would be busy with work all alone for the weekend. A special ‘alcoholic’ drink was left behind in the room with a used diaper that was Shinings, holding a camera inside. Flash leaves it for the princess to find and have a nice drink over her husband, ‘strange’ fetish that she wouldn’t believe unless having photographic proof. “Think your wife will enjoy the show? Perhaps not, but let’s see if we can cause a little more fun around here to liven up this boring place.” Flash spiking another drink for the princess to enjoy when looking over the photos, a small mysterious note left for her eyes only to enjoy when she gets home.

Makes his way to the train as it was the perfect time before it to leave and rest up to let his body finish processing the crummy mixture swaying as he flies to the station. A special V.I.P. Cart was set aside for him to nap away peacefully alone seeing as Princess Cadance let him take care of her problem, knowing that Flash was going to see his very special mare for a fun night ahead.
Shining force to sway and slosh around, unable to really fight off his predator now being useless in his struggles, and any force he uses onto the flesh walls around him, tighten only to keep him smoothly seen from any on-goers at the station, them only seeing a very large and unashamed stallion showing his goods to the world. HIs sloshing body slowly melting him away as he was forced to go along with his captor, the only sign anyone would know he was trapped, was the near completion of his cutie mark on the swaying balls, displaying proudly to the world as it sways on the side of Flash. The colorful star shield cutie mark jostling along as Flash trots to the station, being the only hint at where the prince of the empire now resides in his ‘private’ carriage of the pegasus that shows him off proudly.
Besides the full stares at the strange sight of the heavy sack that Flash was getting, everypony mostly kept quiet and shielded any children's eyes that may be around, not wanting them to ask any question of the pegasus walking amongst them, with a flashy shield cutie mark of the prince on the pegasus guard.
Flash, now arriving at the train station, gets the private cart with ease and quickly naps away when the train lurches out of the station shortly after his relaxation inside. Flash easily gets some sleep as the train rocks him to bed, his sloshing sack rocking gently along with each bump the cart crosses, his dreams filled with the taunting pictures of Shining that was now part of his growing body. The little stallion is not even much of a fighter now during the travels as he was fully churned away in the swaying sack along the ride to his sister's hometown.

As Flash was letting his cock digest the melting unicorn, his body was absorbing the magical essence of Shining Armour, powerful magic that's been suppressed, adding it to his body and giving a small bulk boost to his body. Flash learned a few months ago of ways to add some height to himself, wanting to impress a special mare very soon, wanting his best hoof forward. Even if said mare was already dating him, he needed the obstacle of the prince out of the way, knowing he would never approve of him. Perfect way to impress his mare, and get the overprotective prince out of their way, and a good way to humiliate him at the same time was a nice bonus. The cherry on the humiliation cake was that he was going to use that nice stockpile of baby batter for his mare when he was planning to visit very soon.
Now with the full magic added as his own, it gave the most noticeable growth to him. While the magic of the ‘Crystal Heart’ to the maids gave a few inches, Flash was more of a large Earth pony in build now, possibly near the same size as a familiar red stallion in his mare’s hometown.

“Well this is a nice new look you gave.” Flash comments as he awakens to the rising sun, the train soon to be in the ponyville station. Currently the growth spurt pegasus was standing in front of a mirror, looking over at his new highest, and still sporting a large sloshing sack about the size of a colt.
“I didn’t think this magic would give THIS big of a change, those mares only did a few inches together, but you cum shake, gave like a full hoof in height and bulk to me! Least you were good for something after all, perhaps you will give one more surprise to that sister of yours when I make a surprise visit to her at that school of hers. Hehehe” Flash now pressing his wings to the heavy swaying sack, teasing himself slightly as he ‘talks’ to sloshing cum of Shining. Rubbing the nice addition of the temporary cutie mark on his sack as he looks it over, seeing how it clashed with his heavy sloshing sack. “Going be so hot doing it on her desk I bet, right where she works. Let her remember this day as I breed those chubby teacher flanks of hers! MMph…Let’s skip the waiting and get going now.”

Moving towards a window, Flash quickly leaves the slowing train once it was near its arrival, easily letting him slip un-notice by any passengers that may get an eye candy view of Flash jewels. With a short flight to the castle, It was easy to find where the mare was working, as she kept a tight schedule Flash could follow with ease. Sneaking to the third floor, Flash stealthily watches inside the room, seeing a purple Alicorn working hard on some school reports, all alone today it seemed. Princess Twilight Sparkle sister of the now sloshing cum form of Shining Armor, was unknowing of her colt friend sneaking behind her.

Slowly sneaking up, Flash Sentry gets right beside Twilight, wings spread out as he gently gives a loving kiss to her neck with his wings wrapping her in a soft hug. “Hey there pretty mare, how's my Sparkle butt doing?” Flash ask, slightly startling his mare as she tense under his hold before relaxing

“Celestia Tits Flash! I told you not to sneak up on me when I’m working!” Twilight scowls at her coltfriend, only getting a double take as she notices the new look. “Flash? Have you been working out?” Twilight reaching a hoof out, feels her coltfriend toned chest as she looks over the new look of his. “You are so defined in each area of your muscles now. Has the Crystal Empire agriculture food diet been affecting you this way? Or are you on a muscle or spell work enhancement?” Twilight starts on a small walk as she looks to Flash, hoof feeling his broad chest and body some as she gets into little science talk on the potential of a new discovery.

“MMph. Don’t worry about that, for now let’s focus on this moment here and now.” As he gives one more deep kiss to his mare, before backing up and showing off his once more erect shaft to his mare. “I got a special delivery to make, and it’s going right into that oven you have here.”

Twilight blushes harder at seeing and feeling Flash throbbing cock, and the even large cum sack of his being slowly pressed to her side, rubbing gently into her coat. “F-Flash!? O-o-oh my Luna…. You have a ‘big delivery’ to make if you've been saving up that much! OH! You have to tell me what you did later! Let me get us to my bedroom rig-MMPH!” Twilight comments not seeing the hidden Cutie mark of her brother as Flash begins taking the lead

Just before Twilight could teleport them to her castle, Flash quickly moves in to lick her horn, stopping any spell of hers as the sensitive horn of hers was the weak spot. Slurping loudly and giving a full body hug, with small thrust from how needy he needs the release, Flash knocks some paperwork onto the ground, clearing off the desk. “Mph… No, I don't think we need to take this anywhere else. We got a nice sturdy desk to have our fun right here, and I plan on making this a beautiful moment for us to enjoy it fully here.”

Keeping up his small horn tease to his mare, he guides the clouded mind of the Alicorn to the desk. Getting her to rest her front over it, Flash slowly gets onto her back, the added growth spurt helping him finally able to mount his mare like a true stallion for the first time since Twilights ascend to Alicorn hood. Getting no complaints as he stops his horn lick teasing, and begins thrusting between the foal bearing hips of Twilight’s. Feeling the soft flanks rubbing his cock on both sides with his thrust, as he starts leaking slightly onto her back at the thought of what was about to happen.

“F-Flash…I’ve been needing you for a while now, it is that time of month, but you better be sure you want this, otherwise Shining will have your hide.” Twilight moans hotly as her needy sex was wanting this more then she knew, and was hopeful that Flash would finally quench her flames with all that sloshing cum stored away.

“Oh don’t worry about him. Shining and I came to an agreement and he did help with this set up for us.” Flash plans to tell Twilight later what happened, but for now he has a horny mare to take care of. Backing up to line his hot throbbing dick into Twilight, Flash gives a teasing bite to her neck, thrusting in fully as he begins breeding his mare.” “MMph… We are going to make this official here and now!”

Thankfully with the room being enchanted with Twilight’s own ‘sound canceling’ wards, no pony would hear the near ‘Royal Canterlot’ voice booming out from the mare in the room, Twilight not expecting how much larger Flash was now with his growth. The soft teasing only heightened her experience from the horn and hotdog teasing from her lover. With one deep insertion, Her whole world went white as her horn glowed brightly from the sudden climax. Hot mare cum squirting out and dripping down onto Flash sack as she slowly leaks out her mare cum down her own legs as well.
“OOOOOooooowwwwhoa… It has been a few months…Going to need to get Shining to let up when we get that foal of ours.” As Twilight gets her emotions under control, Twilight looks back over her shoulder seeing her stallion waiting to continue. “I’m ready, let’s continue so you can deposit that thick load inside.”

Flash smirking teasingly at twilight, gives a hard smack to her flanks, getting an extra lewd moan from the mare. “Made you cum already with just one hard thick thrust, guess that means I need to make up for all those lonely nights till we both wake up sore.” Flash teases as he begins sliding out slowly, feeling the clenching walls holding him tightly, not wanting him to leave. With just his tip resting at the edge of the leaking lips, quickly begins pumping himself back inside, getting a rhythm to begin his own release.

As Flash puff’s his chest proudly at how much of a stud he was to his mare, his left hoof pushes Twilight down onto the desk, taking full control of the deep thrusting to his mare. Wings tracing around wings as he hits the feather appendages weak points, the sensitive areas only spiking the horny mare nerves. The body of Twilight is like a specially crafted pottery, each trace deliberate to maximize her natural beauty and pleasure with each hoof or wing feel of the mare. The sounds that she makes with each curve felt and traced along, only adding to the glowing music in the air of their love dance passed down the ages of time.

The animalistic nature of pounding a mare made turned into a true art that Flash learned what was best in this situation. Now with a heavy sloshing sack was a little more tricky, but all the more pleasurable for him as they both wanted the climatic release that would flood the womb within. The vaginal walls spread to its limit with how tight Twilight was clenching, each time when the wet throbbing cock went deep inside. The tip hits the entrance to her womb with all the thrust deep inside, trying to enter inside as it comes to her, slowly coaxing the flesh too open up to accept the coming creamy foal batter. Loud wet squelches and slapping of hips connecting still playing out with each thrust in, the loud moans of Twilight gracing Flash ears, letting him know how desperate his mare was for his seed.

Flash cock continues its ramming with reckless abandon as it goes deep inside, strings of mare juice falling out with each retreat, some squirting out and landing onto the sloshing sack of his. The balls filled with cum moved around as the pounding of flesh happened, slightly deforming around the legs before being pushed away only to come back slapping again against the ponies rear legs. Soft sounds of glorps and churns of excitement could be heard within the sloshing remains, as if ready to give its life seed to fertilize a field that is being given the chance to do so, not wanting another cold night alone in the shower.

Flash grunting and sweating as he keeps up with his thrusting, his head leaning down towards Twilight as he breathes heavily into her ear. “My lovely princess, you make such wonderful noises with my thick cock inside you. How loud can you scream when we stuff you up? Never got you to scream that loud before.” Finishing his speech before Twilight could answer back, he bites her neck lightly as he holds her tightly to himself. Thrusting harder with a slap right on her jiggling flanks as he teasingly bites his mare. Flash moaned loudly into her neck as he felt her tighten even more around his flaring cock as holding himself for a moment longer to enjoy the pleasurable tingling sensation up his spine at the clenching wet vaginal walls, Flash pulling back to quickly continue his fun.

Twilight was lost in her mind, thoughts all blank beside the need to be bred as a needy mare that she was currently, legs spread wide for maximum tightness to keep the cock snuggly secured inside as her pussy welcomes the thick intruder in. Her wings flapping softly, not to escape but nerves shooting off at all the traces of pleasure going through her body. Her horn was glowing softly as she was lost to the spiked pleasure, letting her body freely do as it wants, one being her magic being released dangerously if the ponies aren't careful with a magic outburst. Flash used to her leaking magic during her times back then, but never as a mare in heat as an Alicorn before.

“MMph…Seems you're getting close already again. Whew… Hope you're ready to be fully stuffed!” Flash, seeing the glowing signs of Twilight peak quickly approaching again, himself feeling his own cock swelling slightly as his own climax was nearly here. Moving a wing towards Twilight's neck, forces her to lean back, getting her glowing horn right towards his face as he licks his lips happily, looking forward to getting her to reach the needed peak.
“What…” Licking just the tip slowly from Twilight's horn, the glowing horn sparking softly in further excitement at his small tease’s, Flash feeling the leaking marehood squirting slightly onto him with her twitching erratically on him, clear sign she needed just one more tease for her to cum all over his cock again. ”…Does my mare want to happen?” Flash wanted to hear her say the magical words before taking her horn.

“AAah…S-suck… suck o-aaah! Mmph…” Twilight trying to find her voice from being impaired by the throbbing cock inside, her limit reached once again by her lover.

“Come on Twilight, use your words. You are the Princess after all and need to speak clearly to give orders to your subjects.” Teasing the princess as Flash whispers in her ear, nuzzling the side of her head as he waits to be given permission to finish his fun.

“SUCK MY HORN! CUM IN MY ROYAL PUSSY AND FI-AAAAGGGHMMMMPH!” Twilight didn’t get to finish her Royal speech as Flash immediately shoves her horn into his mouth, suckling loudly onto her with the tongue covering the around her head as he holds on to her tightly, keeping her steady as he gives a few more hard thrust to the spastic clenching walls of her vaginal tunnels. With the few more thrust into the tight love hole of his mare, Flash pushes as deep as his flare dick could reach, entering deep inside and past the entrance to her womb, the first spurt of thick cream melted Shining Armor cum, filling the womb up with the first spurt inside. Flash sack continues to give more loads of melted brother deep into Twilight, the womb forced to take everything it gives as Twilight belly expands to accommodate the thick creamy mess inside.
Flash suckling loudly on to Twilight’s horn as he keeps depositing more and more thick gallons of cum into his mare, the balls slowly shrinking as the womb expands to receive the milky cum mess.
As Flash enjoys the tasty horn in his mouth, the mare under him has her eyes going solid white from magic stimulation overload, the magic inside her core going wild to the unsuspecting pegasus that only further spikes the flame within. Twilight starting to levitate off the ground in a large magical aura as she encompasses around her and Flash, before a burst of magic lunches out of her horn, directly into her lovers mouth as he was shot off her, dislodging himself from her back as he falls into the chair of Twilight to be a cushion seat to catch him. His cock that was nearly down with cumming into the mare, had one last spurt to give that was shot all over Twilight back, as it leaves the now cum dripping womb of all his precious deposited seed.

After a blinding light show, both ponies begin relaxing from the light show, as Flash lays back in the chair, once heavy sack now a more manga left size if only slightly larger, Himself not seeing anything wrong as he was focused on Twilight for the moment as he slowly wipes his eyes from the blinding light show that happen just now. Looking over as Twilight was draped over her Desk, her mane and tail looking be longer and starting to blow in a nonexistent wind slightly from what he could tell, but noticeable was the she seemed to grow a bit, looking like she was now more Celestia size then her former babysitter Alicorn.

“Twilight? You okay?” Flash, sounding concerned, gets off the seat and walks around the more disastrous room as objects were thrown about further. Getting up to her head, he begins checking on her, making sure that his marefriend was alright before panicking could take hold of him. “Whew, guess we overdid it today. But Come on Twi, I’m here for you.” Flash sounding little worry for the mane gently rubs her head, getting a soft groan and fluttering eyes opening to the world.

“Rrrghmp…F-Flash? Is that you?” A groaning Twilight ask as she comes too, looking at the blurry figure infront of her that slowly clears up to her coltfriend that just gave the best sex of her life today. As she stares into the eyes Of Flash, she notices even more the strange situation they were now in. “When did you get a horn?”

Flash only gives a confused look as he crosses his eyes looking up, a hoof feeling his head and bumping into an hard object that wasn't there a few minutes ago. Flash eyes widening in panic as he thought maybe something was in his head, further panicking Twilight as she wasn’t expecting her own sudden growth spurt to happen suddenly, the room filled with loud surprised screaming as they looked themselves over hoping that nothing was permanently health harming. Twilight with a leaking womb of stallion essences dripping all over her carpets, while Flash was getting used to his new horn on his head.

As the two ponies slightly panic for a short time, the two hold themselves together at the unexpecting turn of events. Flash now about the size of Twilight’s height before her current growth spurt and was sporting a horn, making him a nearly formed Alicorn for Equestria. Flash, unknown of how or why, but didn’t matter much to the lovers as now he could be with his mare together for the rest of their lives.
Twilight was all the more happy to actually know Flash would be right alongside her, going through life as husband and wife together making Equestria a brighter future for tomorrow. Even if a few ponies may end up missing with Flash wanting a little more surprise fun with his Princess. The nearly formed Alicorn made a great addition to the protection of the country as he led the troops as Equestria Shield and Sword, helping all who would seek shelter under their rule to spread further friendship and happiness.
Nearly a year later of the happy lovers being together after that morning of fun, Twilight would give birth to a happy little alicorn colt that would be running around and bringing further joy to the two as they had their own little one to raise. Twilight couldn’t be happier and consider all the sacrifices Flash made worth it to have this moment with him in her hold during those cold nights. Shining Armor a forgettable experience as she had her stallion to fill the void, just as he did all inside her, giving the last useful present Shining could ever do, being the seed to her offspring to Flash and herself.

Though a day after Flash left with his prize from the empire tucked away safely down his cock. Princess Cadence returns with her daughter Flurry Heart, tucking her into bed, she takes the mysterious items to her and Shining’s room, looking it over in further detail as she goes through photo of a little colt dressed in Flurry’s clothes, noting that the cutie mark was of her husband and he seemed to be playing around as a child. “Celestia damn it Shinny… Those were Flurry Heart favorite Pajamas, and they are ruined now! UUrgh!” Cadence looked at the bottle left from her daughter’s room, sitting on her bedroom night stand. Reaching with her magic, she pops the top off and gulps it down, wanting to relax after seeing her husband seeming to enjoy being a colt again. “I swear he comes up with new insane ideas everyday. And he couldn't even fix the mess in Flurry’s room when he was down having his fun! That stallion I swear I would spank his butt if only he wouldn’t seem to enjoy it so much.” Cadence calls it a night, sleeps in her bed, not realising come morning, she wouldn’t have her own magic and be the size of her Daughter as well now.
Come morning, the Empire was in for a rude awakening as a newly alicorn filly threw a tantrum to finding the culprit that spiked her drink, thinking it was Shining Armour for a short time, as the entire empire was on thrown upside down for a month almost as they looked for a way to reverse the spell effect that kept Cadence as a little baby foal sized filly. The Princess of the empire having to turn down several diplomats as she couldn’t face them or being taken seriously in running the empire for her change in appearance. Though at least her daughter had a new fillyhood friend to play with till she was back to her old self. Cadence though, never did find out who spiked her drink or where her husband ran off too, and the camera that was left never gave a clue to the mysterious pony in the room that was possibly also the last one to see her loving, if not weird husband of hers.
