>Prologue

>Having retired to their crystal mansion in Silver Shoals. The two sisters Princess Celestia and Princess Luna. Had ordered Cozy Glow released from her stony imprisonment. 

>After being freed from the statue, the filly was immediately sent to the sister’s private mansion. Few knew why, and even fewer cared enough about the evil pegasus to ever consider asking.

---

>Sitting back in her comfortable chair and enjoying her alone time. Celestia reminisced back to when Cozy Glow had first arrived to her. Now almost three years ago to the day.
>The dazed filly had temporarily been placed behind bars in their basement. Chained down to the floor with heavy bolts and latches.
>Still, she hadn’t really been worried about her escaping. As Luna had taken it upon herself to vigilantly watch over her. Never once leaving her side.

>But before anything could’ve been *done* to their young prisoner. She needed to first finalize a special rune collar—that both her sister and herself—had been working on at the time.
>The collar was to be charmed with powerful magic. Magic that was not only dangerous to inscribe, but also forbidden by Equestria’n law.
>The enchantments on it were to serve two distinct functions. The first function linked Cozy Glow’s life energy to her own. Ensuring that she wouldn’t age as long as she wore it. And the second function sealed away select portions of her individuality. Making her subservient to her and Luna.

>And to Celestia’s great relief. The rune collar, once properly secured around Cozy Glow’s neck, had worked flawlessly. Making her completely safe to be around.
>And thus, she was allowed to roam around the mansion. Doing their various *requests* throughout the day and night.

---

>Groaning, Celestia placed her half-eaten plate of cake aside. Setting it down amongst the array of empty ones. 
>For the last few minutes her upset stomach had been demanding her to use the bathroom.
>Unable to ignore her bodily calls any longer. Celestia, with a strain, got up from her comfortable chair. Venturing forward, into the appropriate room.
	
>Entering her large bathroom she saw Cozy Glow sitting quietly in the middle of it. Precisely where she’d left her about two hours ago.
>”Hello my sun goddess.” She said whilst bowing and greeting her politely with a smile.

>Of course Celestia knew it was just an act on her part. Having been ordered to be well-mannered at all times. 
>These days she couldn’t quite discern whether it was fear or hate that simmered within the girl. She would know if she simply asked her. But she never did.

>Instead Celestia simply patted the pegasus on her head like she would a pet, before seating herself down on the marble toilet just infront of her.
>The large but otherwise unassuming toilet had a plastic insert that would catch anything that fell into it. Removing the need to flush.

>And with her broad posterior now over the seat. Celestia, without preamble, started squeezing and grunting unabashedly on it. Both urinating and defecating noisily into the catch below. Sighing contently as the disturbance within her slowly worked its way out of her.

>Celestia was well aware that it was never sensible of her to eat two full cakes back-to-back. But the delicacies were an age-old weakness of hers. Never able to hold back despite knowing what they would do to her inner workings. Choosing to gladly pay the worthwhile price for her weak resolve.

>And as she relieved herself, Celestia briefly looked forward and saw the worried look now on Cozy Glow’s face.
>Winking back at the filly she spread her hindlegs open. Giving her a better view as she continued filling the toilet.

>A short while longer and Celestia eventually finished going. Feeling both much lighter and better as a result. 
>Standing up from the seat she then took two steps away from it. Turning around—and with a wide stance—hiked her tail up. Exposing herself to the filly behind her.

>Immediately after seeing Celestia turn and lift her tail up. Cozy Glow got up from the floor and rushed over to her side.
>Once next to her, she took out the short stepping stool that was always present besides the toilet. Placing it down on the floor just behind Celestia’s waiting hindlegs. 
>And with it she got up and under her flowing, ethereal tail.

>Cozy Glow with her muzzle now inbetween Celestia’s white haunches. Let her tongue out.
>Gingerly dragging it over her marehood and catching any stray droplets there. Before continuing further up.
>And as she reached her stained tailhole she stopped. Concentrating on the plump, round muscle she began licking any and all brown traces away from it.

>”Mnhhh~," Celestia sensuously purred. Enjoying her probing tongue *wipe* diligently both on, and around her grimy star. Feeling herself constantly clench and unclench whenever she slipped deeper inwards. 

>And after a good minute had passed, the intense slobbering slowed. Receiving a curt kiss on her anus instead; signalling that the *clean-up* chore was done.

>Getting the message Celestia then reached around and took hold of Cozy Glow’s ear. Leading her firmly infront of the recently used toilet. Holding her head just over the white seat.

>”Now, once you’re done taking care of *that*. I want you to wash your muzzle and go see Luna. She’ll be waiting in the library.”

>Cozy Glow found herself wanting to urgently plead. To beg Celestia for mercy as she saw today’s grim offerings below her. The vile stench and the sheer amount was staggering. Making her eyes sting and her stomach cramp up badly.
>Yet all she managed to do was feebly mewl for a few seconds. Before nodding defeatedly to her. Reluctantly sinking her head into the toilet bowl.

>Once inside of it she opened her mouth up and slowly began eating the reeking, wet mush within it. Taking her time and chewing properly on any larger bits that she came across. Just like she’d been told to do years prior.

>”Good girl. Never rush and remember to saviour the taste.” Celestia said whilst gently stroking Cozy Glow’s curly, light blue mane. Hearing her miserably eat and swallow from her warm pile below. Noticing how her shallow sobs grew louder with each mouthful. 

>Celestia with her stomach now settled—and not wishing to be next to her own odorous smell any longer—turned and hurried out the door.

---

>After her sordid dinner Cozy Glow wobbled out into the long hallway. Wanting to vomit but was forbidden to do so by the collar.

>Lightheaded and with uneven hooves, she slowly ventured out towards library. All the while dreading what Luna had in store for her this time around. 
>Silently hoping that the dark alicorn was in a lenient mood today. Or just very tired. She usually didn’t hurt her *as much* if she was tired.

>Her occupied thoughts offering little respite as she neared the double doors she’d been fearing. Approaching them she wanted to stop and run away. Now fighting the collar to intentionally miss them somehow.

>But despite her efforts, found herself opening and entering inside the massive library. Standing in the entryway she nervously looked around herself. 
>Not immediately seeing Luna anywhere she continued further inwards, heading for the reading lounge at the far end.

>Passing by several large bookcases and crossing under an oak archway. She eventually found Luna sprawled out on a red couch. Reading causally from various history books next to a lit fireplace.

>“Mistress Luna you requested me?” Cozy Glow said humbly as she neared her.
>”That is correct,” Luna flatly answered, closing her current book, “I want you to lay down on the stone. On your back with your hindlegs spread open. Anywhere is acceptable.”
>”O-of course my night goddess!”

>Cozy Glow hurriedly walked off the lush carpet she was on and laid down on the cold flagstone floor.
>Rolling onto her back she then spread her legs outwardly. Revealing her fillyhood for her to see.

>Placing her book down on the table, Luna quietly got up and moved over to the waiting filly. Stopping infront of her sprawled form. 
>And then, focusing on her magic, located and teleported over a black, flail whip from her bedroom. 
>The whip was one of her favourites. It was heavy with multiple thick tails attached to it. The ends of which had metal wire discreetly woven within them.

>”Do note that we’re in the library. So tame your voice. No screaming allowed.”
>”Y-yes mistress….”

>With the whip now in her right hoof, Luna threateningly hovered it above Cozy Glow’s delicate nethers. Letting the hard strands loosely grace against her vulva.
>”Make sure to thank me after each lick.” She cautioned, before snapping the whip back—and then down with substantial force—directly onto her bare folds.

>*Crack!*

>Supressing a shrill scream the filly smiled back at her dark queen and thanked her.
>”Th-thank y-you mistress!”

>*Crack!*
>”T-thaank youu mi-mistresss!”

>Shaking and whimpering loudly Cozy Glow continued to hold her legs widely open for her. Making herself easy to hit as she despairingly waited for the next strike to come.

>*Crack!*
>”Thha-nnkk 'fhwah' y-you… 'haah' mistrhess!”

>And by the forth lash Cozy Glow started screaming and crying hysterically from the painful hits. And everytime she did, Luna brought the whip down even harder between her legs. Punishing her for her defiance.

>*Crack!*
>”Gahhhh-aaaahhe! Ahhhfaa-waiihhh, uwahhh-ahhhaahh!”

>”Are you deaf?! I said no screaming!”
>*Crack!*

>Yet the filly was unable to quell her wailing voice. Causing the whipping to get progressively worse with each violent strike. Until the ruthless hits eventually started breaking her skin open. Flaying her most sensitive area.

>*Crack…! Crack…! Crack…!*

---  

>The following morning, and feeling the stinging buzz on her collar, Cozy Glow abruptly awoke from her slumber.
>She didn’t exactly remember when it had happened. But at one point or another she must’ve passed out from Luna’s continuous flogging. Finding herself back in her bed somehow. 

>And so, with a painful limp, got out from her small, canine bed.
>Her uncomfortable round bed was placed on the floor. Directly next to Celestia’s own luxurious, royal bed.

>Climbing up on her spacious bedding, and crawling under the fine covers. She shuffled up and inbetween the sleeping alicorns hindlegs. Quickly locating her heady marehood.

>And once over her mature sex, carefully brought her muzzle down next to it. 
>Letting her tongue out she then started licking her awake. Washing the morning dampness away.

>The serene dream landscape currently occupying Celestia’s mind. Started to alter and fade as a warm tingle swept over her. Beckoning her gradually awake.
>Stirring, and with a red flush, Celestia let out a pleased yawn. Leisurely stretching her front hooves and rubbing her eyes softly.

>Now aware of her bedroom surroundings, spread haunches open. Guiding a hoof under the duvet she took hold of Cozy Glow’s head from the back. 
>Then pressed her face firmly against her folds. Smothering and grinding against her muzzle as a cheap masturbation toy.

>And once she felt awake enough, lifted the covers off with her magic.
>Looking down Celestia saw the ruffled, pitiful state Cozy Glow was it.
>Rubbing herself up and down on her face a few more times. She then let go of her.

>Coughing and clearing the mare juice out of her eyes, Cozy Glow looked up and courteously greeted her owner. 

>”G-good morning my goddess. Did y-you have a pleasant rest?”
>”Yes I did, and thank you for asking.” Answered Celestia back, noticing the severely bruised areas around her waist.
>Tapping on the bed she calmly said, ”lay down next to me, on your back.”

>Doing as instructed the pegasus settled down next to her.
>And as she did, Celestia brought a hoof down and parted her bruised hindlegs.
>Areas of dark purple could easily be seen scattered, randomly about, all over her lower region. From her small teats to her dock. Fur clearly missing in some places, having been torn away. Numerus cracked and clotted scabs were also dotted everywhere. And small pieces of her labia were missing here and there.

>”Did my sister need to heal you afterwards?”
>”Yes, I think so miss, I was bleeding alot. But I can’t really remember.”
>”I see. Well you look fine for the moment. I’ll restore your genitals later. For now, you may continue between my legs.”
>”Yes, of course!”

>Returning below her waist Cozy Glow gently spread Celestia’s cleft open. 
>And whilst holding her lips spread, lowered her muzzle between them and messily lapped at her wet entrance. Slurping and greedily drinking everything she could find from the older mare.

>With a strained breath Celestia laid back on her pillows. Once comfortable she took a hoof to Cozy Glow’s curly, light blue mane. Petting and twirling her hair casually as she ate her out.

>By this point not even the alicorn herself knew how many hours Cozy Glow must’ve spent between her legs. 
>As every morning started the same way for her. Thus ensuring that the filly was *more than* intimately familiar with her privates. 
>Having her not only memorize her feminine taste and shape, but more importantly, how to precisely please her.

>Focusing on her task Cozy Glow’s expertly switched between her clit and her entrance. Using her lips to catch and suck on her winking love-bud a few times. Before releasing it and returning down again; to kiss and lick inside of her warm tunnel.
>And everytime she switched places, she could hear Celestia gasp and strain above her. Pulling and tightening her grip on her mane. 

>Cozy Glow couldn’t quite decide what she disliked more in the mornings. Being forced to depravedly pleasure one of her greatest enemy’s. Or the distasteful things that would always transpire afterwards, in her bathroom.
>And judging by how much her dripping marehood was twitching and winking against her now. She feared that the second part of her *morning routine* was close.

>Breathing heavily Celestia was finding it harder and harder to hold her haunches open. Looking down she saw the filly skilfully trace her slit lengthwise with her tongue. Gracing the sides of her soft, inner walls. Before diving back inside of her. To explore and stimulate her from within. Pushing her ever closer to the edge.

>A minute more and Cozy Glow had completely replaced Celestia‘s previous gasps of pleasure, with throaty, carnal moans. 
>Hearing her openly moan above her, and knowing she was close; returned back to her clit.
>Holding the swollen protrusion with her lips she teasingly circled it with her tongue. Not letting it wink back.

>Already at her limit Celestia tried fighting back the wonderful twinges of delight that jolted through her. Wanting to draw out her pending orgasm for longer.
>Unsuccessfully she instead cried out like a mare in heat.
>Haunches and hips shaking, braying in ecstasy—doused Cozy Glow’s mouth with her love fluids.

>Feeling her suddenly climax in her mouth, Cozy Glow quickly fixated her lips over her peehole. Swallowing her cloudy discharges as best she could.

>And after several short bursts, Celestia slumped down on the bed. Lying still and panting softly. Recovering from her euphoric high.

>Separating from her sex, Cozy Glow momentarily looked down at her now flush and swollen folds, before leaning down and licking up any obvious wetness that she’d missed.

>Celestia shuddered as the filly gently brushed up against her now oversensitive marehood. 
>Eyes closed she focused solely on her breathing. Waiting patiently for the filly to clean her off.
>And when she felt a brief kiss on her sensitive clit, pulled herself upright on the bed.

>”That was lovely Cozy. I know you’d put even the best brothel workers to shame.”
>”Thank you miss….”
>With a laugh Celestia stood up. “Now come along. I know you must be parched from all the shouting and crying done yesterday with Luna.”
>”Y-yes.” Cozy Glow hesitantly answered.

>Helping the filly off the bed Celestia then led her into her bathroom. Closing the door behind them she lifted her up onto a changing table. Having her sit upright on it.
>Using her magic she then levitated over one of her larger baby bottles. Unscrewing the nipple cap before floating the container behind herself. Pressing and holding the rim lightly against her puffy vulva.
>Relaxing into it she filled the bottle up with her morning urine.

---

>Later that day the still limping filly had found herself outside on one of the sister’s four large balconies. Currently lying across Luna’s lap whilst the two princesses were chatting and drinking tea above her.

>Her dark mistress had a hoof on her rear and was stroking her cheeks in a taunting manner. 
>And ever so often, she would reach between her rift, to pull on the thick, bumpy dildo lodged within her sore tailhole.
>Retracting most of it out, before leisurely forcing the rough toy inside of her anus again.

>Luna enjoyed the tight resistance of it. Having merely used her own spit as lube on the dildo. Understanding that the friction would rub her little hole raw each time she forced it in or out of her. 
>And given how loudly Cozy Glow winced whenever she moved the dildo. She knew she was causing her significant pain and discomfort.

>The sisters had received more letters than usual this week. Mostly invitational tickets to various galas or operas. The rest were an eclectic mix of political messages, proposals and simple drawings from their youngest fans. 
>Celestia calmly sorted through the stack of letters before her. Enjoying and commenting on some of the more interesting depictions of herself.
>And once she had gone through all of them. Placed the letters with the drawings aside. Intending to write back to them later.
>Lifting the rest up with her magic she levitated them over the balcony railings. Igniting and burning them away in a bright flash.

>Forty minutes later the princesses, after having spotted a few darker clouds creep in overhead. Decided to concluded their afternoon tea.
>Luna with Cozy Glow still on her lap. Pushed her seat backwards and nonchalantly withdrew the dildo completely out from her inflamed tailhole.
>Holding the dildo up she spotted mostly blood on it, but also small specks of feces at the very tip of it.

>”What’s this?!” Luna angrily stated. Showing her the dildo. “I told you to clean yourself properly! Obviously you weren’t listening!”
>”I-I am so sorry m-mistress! I thou—”
>”Silence! You’re not sorry yet!” She warned as she took hold of the bleary-eyed filly. 

>”Will you please excuse us dear sister. I have an impertinent foal to take care of.”
>”Of course. But try not to get too *excessive* with her this time. She is quite injured enough as it is. And I’d like her to atleast be able to walk. The east garden still needs tending to.”
>”Yes, I know sister. Don’t worry.”

>Leaving with an angry grimace. Luna took Cozy Glow upstairs to one of her larger studies. Opening to door she threw the filly down onto the oak floor. Making her tumble twice.
>Walking up to the hurt filly Luna promptly kicked her over. Cracking a rib in the process. 
>Standing over her she coldly said, “wait here, or I’ll misalign your wings again.”

>Terrified and in agony Cozy Glow got up on her trembling hooves. “Y-yes m-mistress. I’ll g-gladly wait!” She said whilst bowing submissively. All the while trying to ignoring the pain in her side.

>The dark alicorn then left her momentarily. Entering an adjacent room she grabbed a stiff cane and small steel ball. The ball had eight semi-blunt spikes surrounding it. All of which were evenly spaced apart from one another.

>With the two items she returned back to the filly. Placing the items down on a stand by the door.
>Then, using her magic, dragged the anxious pegasus over to the end of the room. Where a wide desk awaited her.

>Once at the desk Luna grabbed her collar and pulled her up on it. Forcing her to lay on her stomach with her hindlegs jutting out.
>Happy with her vulnerable position she then concentrated inward for a moment. Searching and pulling forth several dark, jagged tendrils from her mane. 
>And with four of them took hold of Cozy Glow’s hooves. Surrounding her fetlocks and immobilizing her to the desk.

>Now that she was firmly secured, Luna levitated the spiked ball over. Taking it in her hoof she said: “You are not to utter a single word to my sister about the item I’m about to place within you. Is that understood?”
>”Y-yes m-mistress, I w-won’t….”
>”Good, I’ll remove it after a few days.”

>Using the tendrils around her hindlegs she parted her haunches wide. 
>Reaching down with her free hoof she then held her underage slit open. Checking inside of her before summoning forth six smaller tendrils. 
>Lining them up with her narrow entrance she slid all six rudely inside. Then spread her painfully open the same way a speculum would. Making her whelp from the harsh stretching. 
>Now that she was completely open, Luna took the spiked ball and pushed it deep inside of her. 
>Seeing that the spikes were resting against her soft, inner walls. Slowly retracted her tendrils out. Letting her lips close up.

>”And remember, not a word to Celestia about it!”
>Igniting her horn again she then levitated the cane over. Taking it in her hoof she tapped the rod against Cozy Glow’s rump a few times. Letting her feel the thickness of it.
>”Try to atleast hold back *some* of your vulgar squeals this time. I shall be back here until you learn.”
>As she finished her statement, Luna pulled her tail painfully high with her magic. Holding it up she then raised the cane away from her rear. Waiting until she saw the filly unclench. And when she relaxed, viciously flicked the cane against her exposed cheeks.

>*Snap!*
>”Ffwhhaah!” 

>Immediately as the cane landed on her. Cozy Glow involuntarily clamped down as hard as she could from the searing contact. And the instant she did, the spikes now lodged deep within her, dug painfully into her delicate flesh.

>*Snap!*
>”Aafuuahhi!” 

>And as the caning progressed on. Blood eventually started pooling on the wood below her shaking hindlegs. Dripping out from her torn rear, and from her fillyhood.

>*Snap…! Snap…! Snap…!*

---

>Three weeks later and Princess Twilight Sparkle dropped by the sister’s mansion for an impromptu visit.
>She usually did so whenever she was particularly stressed from dealing with the Canterlot nobles. Needing a day or two for herself to unwind.

>And just like always, Celestia was accommodating and understanding of her venting needs. Being well aware of the difficult facets that came with ruling over Equestria.
>And so, after a brief catch-up, offered Cozy Glow to her.

>Passing her the filly Celestia would always ask which *special* guest room she’d prefer staying in. Her own playroom or her sisters *readjustment* room. Knowing what she could expect to find in either one.
>And this time around she opted for her playroom. Taking Cozy Glow with her as she left.

>Roughly an hour afterwards Celestia went upstairs to check on her former student. Wanting to know if she’d be needing anything else for the evening.

>Standing outside the playroom door she gently knocked on it a few times. Before opening and entering inside.

>And as soon as she did, she was immediately hit by the sour smell in it.
>Entering she saw Cozy Glow seated in the middle. Strapped into an adjustable highchair for baby foals. With her four hooves secured using locking belts.

>Her curly, light blue mane had several pink ribbons in it. And around her neck hung a white bib with a spill catch.
>On the feeding tray below her lay a white, mare sized diaper. The garment was well used and spread open. With its messy fillings on full display.
>And infront of the filly stood Twilight. A fresh diaper covering her plump hindquarters. Waiting to be used again.

>Walking up to the pair Celestia first thought Cozy Glow was squirming because of her soon to be dinner. But then she noticed the discarded manebrush on the bed. 
>That, together with the light coughing and snivelling she was still doing. Made it clear what had occurred just prior.

>Celestia, now standing behind her former student, placed a hoof on her puffy diaper. Trailing downwards she stopped just over her marehood. Digging into the crinkling padding and groping against her folds.
>”My my don’t you look absolutely adorable~,” she endearingly teased. ”Sorry for disrupting your special playtime. I just wanted to make sure you had everything you needed.”

>Blushing and breathing intensely, Twilight slowly turned to face her mentor.
>”No, I think I’m f-fine for now… thank you mo— Celestia.” She said, trying not to stutter.

>”Good, you know where to find me if you do.” Leaning forward Celestia then nuzzled sweetly against her. And as she withdrew from her, whimsically kissed her on the muzzle.

>The kiss caught Twilight of guard. Flustered and bumbling she spun around. Only nodding vaguely to her in response.

>Giggling at her cute reaction, Celestia briefly glanced back to the seated filly. 
>Focusing she teleported over a circular punishment mat from the bathroom besides them.
>The hard mat had several plastic points sticking up from its surface. Excruciating enough by itself to sit on, let alone when recently spanked.

>With her magic she then momentarily loosened the straps around Cozy Glow’s hindlegs. And then slid the mat underneath her raw bottom. Retightening the straps down. 
>Once done with her, Celestia leaned in, over Twilight’s shoulder. “After you’re done feeding her, I want you in my nursery~,” she whispered hotly, nipping her ear.

>As Celestia turned away from her swooning counterpart, she flicked her colourful tail against her diaper. Causing her to shiver from the impact.
>With a swaying saunter she then exited the playroom. Closing the door with a not so subtle wink.

>Having heard the door shut behind her, Twilight let out a heavy sigh. Closing her eyes she tried regaining her composure.
>Her beloved mentor—even with just a few playful words—could make her heart flutter wildly. Reducing her momentarily to a nervous schoolfilly again.

>A few seconds later and Twilight found herself in control again. Successfully fighting off the fiery bloom on her muzzle.
>With her heart quelled she opened her eyes up. Seeing Cozy Glow struggle anxiously on the uncomfortable mat before her. 
>With a calm smile she stroked her troubled face. And then slowly reached for the plastic spoon on the tray. Taking it into her hoof.
>Dipping the spoon into her used diaper, she loaded it up with her dung, before bringing it over to Cozy Glow’s quivering lips.

>“Now open up little one. Naughty foal’s needs to take their bitter medicine!” She said in a giddy tone. 

>With a horrified look Cozy Glow obediently opened her mouth up. Accepting the reeking spoonful of manure inside. Doing her best to chew and swallow the thick muck down as the pain in her rear increased two-folds.

>All the while Twilight unhurriedly continued to bring her spoonful after spoonful. Humming happily along as she imagined all the exciting things she and Celestia would be doing together.

---

>Three days later and Twilight Sparkle returned back to her castle. Exhausted but refreshed, and with a slight hitch in her step.
>During her visit she’d spent most of her time playing and relaxing in Celestia’s private nursery. Seldom leaving it.

>And after having said their goodbyes. Luna went upstairs to fetch Cozy Glow from it. Knowing it was her turn to be alone with her.
>Even though Luna enjoyed teasing the younger alicorn. She also respected her special relationship with her older sister. Understanding that there were certain things she only wanted to do together with her.
>So, for most of the two days, she’d kept herself away from the trio. Letting her sister *care* and *nurture* both of them without interfering.

>Only bring them refreshments every now and again. Knocking and leaving a small service cart outside by their door.
>However, one time she had done this, Celestia had surprised her by opening the door. Dressed in a sunny, light-green apron she kindly greeted and thanked her for the *much needed* drinks. And then asked if she could take the cart inside while she changed. 
>Thinking nothing of it Luna led the cart inside with her magic. Walking behind her sister she saw the smeared strap-on dildo, that was swaying and dripping below her barrel.

>And once inside the room she glimpsed Twilight in the corner. Standing and snivelling with her muzzle planted firmly against the wall. Her tail held high and her bottom soundly spanked. With an oversized plug protruding out from her tailhole. The short, frilly skirt she had on did nothing to cover anything up. 
>And on the spacious crib bed in the middle, lay Cozy Glow with a completely soaked diaper, tied loosely over her face. Her hindlegs were spread and a hollow dilator sound had been inserted deeply into her urethra. Leaving her peehole tightly open.

>Parking the cart Luna then saw her sister switch to a very rough looking strap-on dildo. The girthy shaft was covered with multiple high ridges and round bumps—that trailed irregularly alongst its impressive length. And a cone flared base—meant for serious stretching—could be seen at the hilt of it.
>Even for an alicorn nothing about its shape seemed pleasant or comfortable to take. Feeling thankful she wouldn’t be on the receiving end of it.

>Watching her sister secure it inbetween her powerful legs. She then nodded to her and quietly left the humid room.
>And as she shut the door, she overheard Celestia call over to Twilight; telling her to “bend over the bed.” Smirking, she didn’t stay to listen in on the ensuing begging and crying.

>Now standing outside the same nursery door. Luna prepared herself for some rather *impure* sights and smells. 
>Opening and entering inside the brightly coloured room. She tried avoiding the wet sex toys scattered randomly about on the soft carpet. Spying several of her sisters *extra-large* stallion models. Most of which were slick with *displeasing* colours.

>Walking up to the large crib bed in middle where she had last seen the filly. Luna now only saw empty bottles of foalpowder and lube besides it. The bedding distinctly damp and tinged. But no Cozy Glow.
>Shrugging she turned and walked over to the closed bathroom door. Side-stepping the wet spots on the carped and a stack of spelling blocks getting to it.
>Once at the door she quickly opened and peered into it.

>But just like before. Cozy Glow wasn’t inside of it either. Only the completely full diaper pail in the corner, and the discarded enema bags on the white tiling. Stood out to her.
>Surprised by her disappearance Luna closed the door and existed the nursery. Focusing on Cozy Glow’s collar she sensed that she was somewhere in the basement. Next to somecreature that definitely wasn’t her sister.
>Quickly recognizing whom it was she sighed loudly in annoyance. His foul magic was unmistakable anywhere. 
>Shaking her head she unhurriedly made her way down into the basement.

>Arriving at the basement and venturing inside of it. Luna saw Cozy Glow tied down to one of her punishment racks.
>And Discord, with both of his claws around her flanks, was aggressively thrusting in and out of her tailhole. 
>Panting like a wild animal he jutted the wide base of his knot in and out of her. Pulling out just enough for the knot to completely leave her. Then quickly forcing it back in again. Violently stretching her anus open each time and causing her to yelp gutturally.

>”Discord! How many times have we told you to—'ask us first'—before you breed her?!”
>”A few.” He huffed out dismissively.
>Switching from fast to powerful thrusts he started slamming himself between her soft cheeks. Pulling more of his now red-slicked phallus out. Before re-entering her reluctant passage.
>And as he did, Cozy Glow started to scream uncontrollably. Prompting Discord to snap his claws. Summoning a ball gag into her mouth. 
>Having silenced her, he imminently resumed rutting her abused hole. 

>“More than a few!” Luna said annoyed, watching the crude scene unfold. “And you better not pee inside of her posterior again! Neither my sister, nor myself enjoyed that surprise last time!”
>”No promises!” Discord answered. Grunting and laughing at the same time. 

>Feeling an unpleasant headache coming on, the dark alicorn walked back towards the door. 
>Exiting the room she retired to her bedroom for the day.

---

>Bonus: 

As the duo first entered the guest playroom. Twilight Sparkle first led Cozy Glow to the bed. Motioning the filly to sit down on it.

>”Wait here little one, I need a moment to get ready.” Twilight said as she walked into the adjacent bathroom.
>As she entered the spacious, marble tiled room she spotted the two shelving units that lined the far, rightmost wall. 
>And just like last time. The shelves were stocked full of assorted goods for any playtime scenario imaginable. Containing everything from sex toys, diapers, baby bottles, catheters, rectal thermometers, incontinent drugs and much more.

>Seeing all the explicit items now infront of her, caused a cascade of giddy and lustful emotions to surge within her. Especially as she saw the more *taboo* items on display.
>Licking her lips she walked up to small box of lactation inducing drugs. Turning the box over she started to blush as she remembered back to her previous play session with Celestia.

>Back then she had found herself dressed in a pink onesie. With padded, pink mittens covering her hooves and a frilly, white bonnet on her head. Lying sideways with her head resting comfortably on Celestia’s soft lap. Happily suckling and drinking from her perky teats as a gentle, loving hoof stroked her mane.
>The back flap of her onesie had been left open as an enema bag—that hung above her—slowly filled her thickly diapered behind.
>However, it wasn’t until the following morning. After breakfast with both Celestia and Luna. That she had gotten her diaper changed. 
>She didn’t know what had been more humiliating at the time. Being bounced on Luna’s lap whilst Celestia took away the empty dishes. Or being changed infront of her aswell as she teased her throughout.

>Embarrassed Twilight placed the box back on the shelf. Swallowing hard she wiped her forehead with a hoof. Feeling her marehood dampen at her past memory.

>Walking away from the shelves and into to the middle of the room. She ignited her horn and pulled off one of the larger changing mats that were hanging on a wall-mounted bar.
>Placing the plush mat down on the floor she took a final look around herself, before laying down on it. 
>Once comfortable she levitated over a white, thick diaper and two suppositories from an open jar.
>Lifting her hindlegs up she slid the diaper underneath her rear. And then inserted both suppositories into her tailhole. Using her magic to push them far up inside her rectum.

>Content that everything was in order, she then lowered her legs down. And with a hoof reached down to close the cover over her marehood. Joining and taping the diaper shut.

>Judging by the warning label on the jar Twilight knew the suppositories were fast acting. 
>So, with no time to spare, got up and walked over to a smaller corner shelf by the door. Perusing the selection of various spanking implements on it. Before opting for a simple manebrush. The same kind Celestia usually used on her own purple hide.
>Satisfied with her choice—and already feeling her stomach begin to protest—quickly existed the bathroom.

>Walking up to Cozy Glow she could easily hear the audible crinkle of her diaper.
>Normally she’d be self-conscious of such things, but currently there was no reason for her to be. Seeing the frightened look on Cozy Glow’s face as she neared with the manebrush; only ensured that notion.

>”Cozy I want you to scoot up on the bed and lay down on your back for me. I need to use my diaper.”
>”Y-yes miss.” She obeyed. Quickly shuffling further up and laying down in the middle of it.

>A few seconds later and Cozy Glow saw the alicorn get right up besides her. Nervously watching as her much larger frame turned around. Before straddling over her.
>Looking up all she could now see was her padded rear hovering just above her face.

>And as she got situated Twilight felt her stomach aggressively bubble and churn from the melted suppositories. Groaning from the sharp cramps she lowered herself further down. Pressing her diapered rump against the filly's muzzle. Aligning the pointed end of her nose directly up with her exit.

>Not a moment later and the princess suddenly felt herself burst below. Expelling noisily into the diaper without any control of her own bowels. Transforming the once white cloth around her flanks brown.

>And as she filled her diaper up the harsh cramps that had been bothering her, slowly subsided away. Leaving her both empty and relieved in the process; and with better control of her insides again.

>Noticing that nothing else was forcing its way out of her tailhole. Twilight, now finally at ease, started to rock back and forth on Cozy Glow’s face.
>Using her muzzle to spread the smelly mess out. Coating her entire backside with her manure.

>And after sensing a pleasant, lumpy warmth all over her bottom. Twilight lifted her hind away from Cozy Glow. And in doing so caused the filly to instantly cough and sputter loudly. Drawing in as much fresh air as she possible could.

>Laying down next to her again, the alicorn patiently waited until she finished recovering.
>”I’m thankful that you’re here Cozy. I didn’t really get a proper chance to use my bathroom before leaving the castle.” She said whilst reaching around herself, squeezing on her full diaper. “Would you like to assist me with the *cleanup* aswell?”

>”O-of course, I’d l-love to miss.”
>“Such a helpful filly, I knew you wouldn’t mind. But unfortunately, you’ve also *misbehaved* a great deal in the past, haven’t you Cozy? And because of that I believe a warm hiney—will help remind you—to always stay true and virtuous. Don’t you agree?”
>”Y-yes… please….”

>Supressing a snicker Twilight wordlessly got off the bed. Wanting to first feel her used diaper before anything else.
>Walking over towards the end of the bed she could feel her bulging diaper shift and stretch on her flanks. Her diaper trying to adjust and compensate for the large mess now within it. 
>A good portion of the warm manure tumbled downwards as she walked. Gathering just below her marehood. Pressing teasingly up against her folds.
>That, combined with the thickness of the diaper. Gave her an awkward waddle whenever she moved.

>Flustered, Twilight reached the end of the bed. Sitting down on the edge with a crinkling squelch. Needing to *accommodate* for her soiled diaper by re-positioning herself a few times.
>And once she was comfortable enough. She waved the filly over.

>With timid reluctance Cozy Glow crawled up to her. 
>And as soon as she got close. Twilight lifted her up and over her cushioned lap.

>To Cozy Glow the foul smell came back in full force as she was placed down on her diapered lap. The overbearing stench of it filled her nostrils no matter which way she leaned or turned her head. Making each breath a struggle.

>”There we are. Now listen closely little one,” she said sternly whilst fondling her hind cheeks, ”you’re allowed to yell and fuss about. However no reaching back to me or trying to get away. Understood?”
>”Y-yes m-miss.” 

>Eager to begin Twilight didn’t acknowledge her. Instead she removed her hoof from her rear and pulled Cozy Glow’s tail up and to the side. Revealing her pink bottom.
>Tucking her tail against her own body, she then picked the manebrush up on her right.

>Now holding her close took the manebrush to her rump. Tapping and caressing both cheeks with it for a brief moment. Enjoying the cute little flinches from the filly below her. Before drawing the brush backwards.
>And then, feeling herself wink against the manure in her diaper, slammed the brush down with considerable force.

>*Smack!*
>”Eyyha!” 

>With wide open eyes Cozy Glow shrieked loudly as she felt the hit register on her right cheek. Unprepared for the cruel force behind it. Her previous worries quickly turning to fears.

>To Twilight the contrast was undeniable. Normally when spanking colts and fillies back home, she’d exercise *some* restraints and limits to her physical punishments. And even though she secretly delighted in hearing the little ones snivel and cry beneath her. She would atleast *try* and balance their needs for guidance and discipline; with her own enjoyment of spanking their soft bums. This was especially true if the foal or young creature came from someone she knew, or was from a good family.
>But unfortunately for the filly below her today. There was no need to hold back or consider anything at all.

>”Bad girl!” Twilight yelled. Excitedly striking her left cheek just as hard. "You’ll be good! Say it!"

>*Smack!*
>”Ahiiee!” 

>”I-I’ll be good!”

>*Smack!*
>”Uunfha!” 

>”I-l’ll 'h-ah' be g-good!”

>”Then let’s make sure of it!” Twilight scolded. Gripping the manebrush harder. 
>And with a firm hold of it. Began paddling her pink cheeks repeatedly. Alternating her hits evenly and squarely. 

>*Smack! Smack! Smack!*

>The effects of the faster strikes were immediate. Cozy Glow wailed piercingly as the smarting blows impacted on her hide.
>And like she was allowed to do, started bucking and kicking fervently. Arching and waving her hooves all around herself in reflex. 

>”Gahhaa, owahh-fhaaa! Ahhhhheeeii!”

>*Smack! Smack! Smack!*

>”I-l will be—'ha-ahhh, hahhiii!'—be g-good! Ohof! Ow, pl-please 'fwha-ahhaa!' it h-urts!”
>Disregarding her pleas Twilight instead shamelessly rolled her diaper back and forth on the bed. Pushing and rubbing the mess against her slick folds. 
>Pleasuring herself whilst stacking more and more oval-shaped bruises underneath the filly’s fur.

>*Smack! Smack! Smack!*

>Unable to take the rough blistering Cozy Glow pounded on the bed and bit into her hooves in desperation. Maddingly wanting to get away but was uncapable to even try.
>Nothing she could do would lessened the stinging pain currently being delivered on her already throbbing behind. 
>And after two minutes she gave up. Covering her eyes she started sobbing and crying foalishly.

>”Uwhhahhh, wahhhahhhh uwhhahh-wahhahhaa!”

>*Smack! Smack! Smack!*

>Yet her anguished cries were completely outdone by the sharp sounds of the manebrush still crashing down on her quivering rear.
>As her tormentor was in no rush to end the chastisement early. Relishing both the spanking and her stained diaper too much to stop.

>*Smack! Smack! Smack!*

>Author's notes (feel free to ignore)
>The basis for this story was to utilize a simple concept and then expand upon it whenever I could do so. 
>The concept in this case was to use Cozy Glow and put her through various torments everyday. Each day/night was to be just a short story detailing something specific.

>However with such a flexible format its hard to know when to stop. So I’m ending things here for now. If I don’t I’ll never end up editing it properly lol. Perhaps I’ll add more day/nights in the future.

>Also the bonus part was originally meant to be a standalone bonus story, but I put it in here instead. That’s why it’s abit longer than the rest.

>Thanks for reading!
