Starlight attempts to recapture the whimsy of her childhood with Sunburst.

Starlight Glimmer thinks the best way to spend time with her old friend Sunburst is with a bit of age regression magic. As is the case with most of Starlight's attempts at solving her problems with magic, it goes horribly wrong incredibly quickly.

Starlight bustled about the castle’s guest room, getting things in order for her guest. Sunburst would be there soon, and his room was still too cluttered for her liking. She was determined that, unlike last time, this visit would go perfectly. All she had to do was play it cool, keep her head on straight, and not freak out like she did before, and things would be fine.

“Starlight! I’m here!”

Starlight’s eyes went wide, but she tried her best to stay calm. Okay, so the room wasn’t ready. No big deal. This was an easy fix. All she had to do was dig up that time travel spell, go back about an hour, thus compromising the very fabric of existence, and then—

Starlight stopped herself with a firm shake of the head. That was the old Starlight’s solution. But things have changed. She was wiser now, and slightly less of a compulsive psychopath. She could handle a minor inconvenience without resorting to dangerous, unstable, experimental magic.

“Coming, Sunburst!” Starlight quickly made the bed with a deft flourish of magic, then, deciding that it was good enough for now, departed from the guest room to greet Sunburst. She all but ran down the stairs to the map room, where her old friend was waiting for her. Starlight couldn’t help but smile whenever she saw Sunburst. He was such a sweet, if awkward, stallion. Despite his beard, which Starlight secretly adored, and the heavy bags under his eyes (no doubt from studying through the night), Starlight couldn’t help but see Sunburst as the same awkward, anxious colt that she knew as a child.

“Starlight! It’s good to see you!” said Sunburst, setting down his suitcase. Starlight approached him and gave him a hug, which he happily returned.

“Good to see you, too,” said Starlight. “I just wish it didn’t have to be work-related. They work you too hard up there!”

“Heh. You’re sounding like Princess Cadance.” Sunburst awkwardly scratched a hoof through his mane. “She’s been hinting that I should take a vacation soon.”

“Hinting how?”

“She hid a brochure for an air cruise in my breakfast this morning,” he chuckled. “But I can’t leave her and little Princess Flurry alone for too long. There’s so much that needs doing around the castle. Soon, Flurry’s going to need magic training, and that means suppression runes, charm tomes, mana crystals, and who knows what else.”

“Wow! Sounds incredible,” said Starlight, still a bit awestruck by the responsibilities of a princess’ Crystaller. “I imagine that’s why you’re here?”

“That’s right. Princess Twilight said she had some books and equipment she’d be willing to donate to Princess Flurry, and I’m just here to get that going.” Sunburst smiled awkwardly, adjusting his glasses and his cloak a bit. “Where is Princess Twilight, out of curiosity?”

“She had to step out for a bit to handle some school business,” explained Starlight. “So you’re going to have to make do with me for now.”

“Oh, don’t sell yourself short. It’s more than ‘making do’. This is perfect, actually! This can be a mini-vacation!” Sunburst clapped his hooves excitedly. “How about we do some catching up and hanging out while we wait for Princess Twilight?”

“Sounds good to me! What do you suggest?” asked Starlight. Sunburst hummed in thought, pacing slightly out of some inescapable habit.

“You were always more of the planning sort. Did you have something in mind?”

“Well…” Starlight fidgeted slightly, uncomfortably. “I do, but…”

“But…?”

“Well, let’s get you to your room. I’ll tell you on the way.” Starlight lifted Sunburst’s bag with her magic, then led the way to the guest room. “Promise not to make it weird?”

Sunburst was, understandably, on guard upon hearing that. Starlight had a habit of, to use nice terms, being a basket case, and she normally was oblivious to her own blatant insanity. If this was weird enough that even Starlight thought it was worth mentioning, Sunburst would need to buckle up.

“Er… Promise?” Sunburst followed Starlight through the castle, his guard thoroughly raised.

“So, you remember the last time you were here?” asked Starlight, mostly rhetorically. Sunburst’s last visit was something that neither of them were likely to forget any time soon. “When I, uh…”

“Used weird age regression magic on me without my consent?” offered Sunburst. Starlight chuckled nervously, pushing open the door to the room where Sunburst was meant to be staying. It was a bit cluttered, but it was more than adequate for Sunburst’s short stay.

“Pardon the mess, and it technically wasn’t an age regression spell. It was simply an illusory charm that made us look like children.” Starlight set the bag on the bed, tossing the last of the books that littered the room onto their shelves with a flourish of magic. “In order for it to be an age regression spell, it’d have to revert our bodies and minds to when we were foals. Technically.”

“Fair enough. So, what’s the thing you wanted to do that I’m not allowed to make weird?” asked Sunburst.

“I want to use weird age regression magic on you.” Starlight gave a nervous chuckle. “With your consent, this time.”

This was one of the various instances, both as adults and as children, where Sunburst questioned his friendship with Starlight.

“What?” Sunburst blinked a few times, trying to make sense of Starlight’s insane suggestion. “Why would you want to do that?”

“Well, I was thinking recently. About how things used to be.” Starlight fidgeted nervously, noticing her friend’s intense confusion and concern. She was a bit relieved, truthfully. Unease and uncertainty were probably the best reactions that Starlight could realistically expect from Sunburst at this point. “And things used to be a lot easier when we were foals. So, I was thinking… What if we went back to the good old days? Back to when we were kids and were carefree, when things were fun and we had nothing to worry about?”

“I… That’s crazy, Starlight. Can you even do that?” asked Sunburst. Starlight nodded, using her magic to summon a scroll of parchment on which she had scribbled her various formulae. She hovered it to Sunburst, who looked it over a few times in search of errors. “Hm… A proper age regression charm… But if you turn us into foals, kids who are too magically inept to do much more than levitation, how are we supposed to be turned back?”

“Built-in failsafe. The way the spell is constructed leaves its structure intentionally unstable,” explained Starlight. “The spell will fall apart in about an hour and everything will revert to normal. It’d be perfectly safe and totally reversible. Absolute worst case scenario, Twilight comes by and fixes us. I’ve never cast a spell that she can’t undo, and I left a note on her bed explaining the situation.”

“You gave this a lot of thought, haven’t you?” sighed Sunburst. “Well… I have been stressing a lot lately… And, if you’re certain it’s safe…” Sunburst let out another long, tired sigh. “Fine. Let’s do it.”

Starlight’s eyes lit up, and she immediately began casting the requisite magic before Sunburst had the chance to change his mind. She cast her spell layer by layer, letting her magic tug and pull at reality. She enveloped herself first, then Sunburst, absolutely elated that her plan was going off without a hitch. She was surprised beyond belief that Sunburst didn’t notice the other part of her spell.

Besides the age regression, Starlight had also implemented a variation of the Want It, Need It spell she had learned from Twilight. Not a very strong variant, just enough to get Sunburst’s attention and hopefully compel him to have some steamy foal-on-foal sex with Starlight, just like she had always dreamed. She knew that using magic on somepony without their prior knowledge or consent was a bad thing, but she thought this would be an exception. What could be bad about helping your best friend get laid?

The magic swirled around the two, surrounding them in a bright, white light. The brightness grew more and more intense before popping into a shower of sparks, revealing the results of Starlight’s magic. Her body had shrunken down to the size of a filly, and she could feel her magic diminish commensurately. Even her mane had changed to better suit her new stature, adopting the adorable pigtail style she formerly wore. She grinned at her success, filled with that unique joy and contentment that only came with being a child. She turned to see her friend, her grin falling into a confused frown.

“Huh?” Starburst looked down at himself, confused by his form. As far as he could tell, nothing had changed. He was the same size and age as he was before the spell, except now he felt a strange light-headedness. He blinked groggily, trying to get a grip of himself before he passed out. “What happened?”

“Oh, darn it!” said the filly Starlight, pouting her lip in an adorable display of frustration. “I must’ve gotten the charm thingy wrong… And your magic isn’t good enough to cast the spell on yourself or turn me back, so…”

“My magic isn’t good enough?” Sunburst knew that Starlight was objectively correct, his spellcasting definitely not his strongest suit, but he felt an irrational rage overtake him anyway. “What the hell is that supposed to mean?”

“Hm… Maybe we can go find Twiggy,” mused Starlight, uncertain as to why she just referred to Twilight as ‘Twiggy’. She concluded it must be part of the regression spell. “She should be able to—EEP!”

Starlight felt a tug of magic yank her up into the air and deposit her unceremoniously onto the bed. She watched Sunburst approach, shedding his cloak as he neared the filly. It was only at that moment did Starlight realize how potentially scary Sunburst was. He was at least twice her size, physically strong enough to toss her around however he wanted. Starlight felt her body grow warm, her little foal pussy tingling in anticipation. If she could convince Sunburst to fuck her now, it might be even better than she hoped.

“You wanna say that again?” huffed Sunburst. “Think you can just get away with calling my magic weak?”

“W-well, it is!” Starlight tried to stand up, just to be firmly pushed down by Sunburst’s big, strong hoof. “You better go find Twiggy so she can turn me back.”

Starlight surely would have said more if not for Sunburst rearing his hoof back and smacking her across the face. The filly flinched, her eyes immediately welling up with tears. Starlight was not expecting that. She’d known Sunburst for most of their lives and she’d never seen him hurt a fly. He was not a violent pony by any stretch of the imagination. He was a kind, tender soul.

Which made his visual arousal at Starlight’s pain even more disturbing.

“Oh, you didn’t like that, did you? Little bitch!” Sunburst smacked Starlight again, harder this time, causing her to outright burst into tears. “Oh, don’t cry, you stupid cunt. That’s nothing compared to what I’m going to do to you next.”

Starlight, even as a small child that lacked advanced thinking and much of the intelligence she enjoyed as an adult, realized that she may have fucked up big time here.

“B-bursty hit me!” bawled Starlight. “W-w-why?!”

“Cause you’re an annoying slut and you fucking deserve it!” Sunburst was a bit confused as to why he was being so aggressive, why his language was so coarse. He had never been much for swearing, but something about the way Starlight flinched was sending arcs of excitement through his body. He felt his cock grow hard between his legs at her fear, Starlight’s terror making his thick, meaty shaft twitch in anticipation. Starlight sniffled, squirming as she felt Sunburst’s cock drool precum onto her belly.

“B-bursty?” sniffled Starlight.

“Bursty, Bursty, Bursty! Annoying little bitch!” Sunburst, grabbing Starlight gruffly around the throat, making it difficult for her to breathe and even harder for her to keep whining. “I’ll give you something to squeal about!”

Sunburst pressed his cock against Starlight’s tight, underaged cunt, letting out a low, almost bestial groan from the wonderful, delicious resistance. Starlight screamed, fighting with all of her meager strength to escape. Unfortunately for her, Sunburst was plenty strong enough to keep her down, and he was not above using that strength advantage on this poor, defenseless filly.

Starlight’s screams reached a fever pitch from the sudden pain of Sunburst’s cock popping into her pussy. Tears streaked down her face, as did blood down her thighs from her stretched, torn labia. The pain was intense, racking Starlight’s tiny body, but Sunburst gave her no reprieve, no time to acclimate to the agony she was currently feeling. Sunburst just kept pounding, thrusting his cock viciously into Starlight’s bleeding, ruined pussy

“P-please!” begged Starlight as Sunburst pumped his cock into her, feeling the tip of his cock slam against her cervix. “Stop! It hurts, Bursty!”

“Shut the fuck up! You think this hurts?” Sunburst laughed madly, pounding Starlight’s tight, convulsing, bleeding cunt harder. “It’s only gonna get worse from here!”

Sunburst gripped Starlight’s hind legs with his magic, pulling her closer and ramming her harder and rougher. He used her like a toy, completely disregarding her pleasure or safety. Just when Starlight thought things couldn’t get any worse, she felt Sunburt's magic reach into her hip, tugging at the joint holding her left leg and pelvis together. Her skin split, blood slowly dripping from the tear. Starlight felt her leg twist and turn, her bones creaking painfully. Sunburst’s grin grew with Starlight anguished scream, reaching a head when her little leg snapped in two.

Sunburst kept twisting, letting Starlight’s scream push him further and further until he had pulled off the entire leg, letting the blood spew from Starlight’s severed arteries like a crimson fountain. Sunburst dropped the torn, snapped limb onto the filly’s face, laughing when Starlight swiped it away in horror. He had done a number on her, splintering the bone when he snapped it off and leaving a jagged point jutting from the severed limb. Starlight quaked and trembled from the pain, her sobs devolving into hysterical, nonsensical begging.

“Oh, does that hurt, bitch?” asked Sunburst, gripping her right leg just like he had the first. This time, he was much quicker, snapping the bone with a large surge of magic. Though it was faster, it was no less painful for Starlight to have her second leg ripped from her body and tossed into a pile with the first one. “Well, I’ve got to do the others, too. For equality, you know?”

Sunburst seemed to be getting more efficient with each attempt, this time grabbing Starlight’s remaining legs at once. He paused for a second, letting the filly’s screams and begs fill his head before giving a firm, deft tug. Starlight’s screams twisted into a half-sob, half-shriek as Sunburst ripped her legs from the joint, twisting and snapping the bone until the limbs were ripped messily from her body.

“There you go, bitch! A perfect little fuck-nugget!” laughed Sunburst. Starlight seemed to be fading, her screams dying down and her thrashing coming to a halt. She was passing out, no doubt from the ridiculous amount of pain she was in. Sunburst growled, then charged his horn with a surge of powerful unicorn magic he didn’t know he had. “Wake the fuck up!”

An arc of energy shot from his horn, connecting with Starlight’s little body. She squealed in pain as she was jolted back to consciousness, her brain struggling to comprehend what was happening. She could feel the flesh of her ruined legs close up around the bone, forming sharp nubs where her hooves once were. Starlight’s eyes were wide with horror, her gaze bouncing around erratically, as if looking for some way to escape this hellish situation. Unfortunately for Starlight, she was lacking in options. All she could really do was endure, pray to the goddess above that Sunburst came to his senses and stopped this madness.

“B-Bursty, please…” begged Starlight, squirming helplessly. Her brain was awash with pain, her thoughts jumbling as she searched for some way out of this. “Please, stop…”

“Understand this, you stupid little bitch,” growled Sunburst. “I’m not stopping until I bust a nut in your cold, dead, filly pussy!”

Starlight babbled incoherently, her words lost in a terrified squeal when she felt Sunburst’s magic grip her around the throat. She gave her friend one last tearful look, Sunburst responding only with a hungry lick of the lips, before she squeezed her eyes shut to accept her fate.

She could feel Sunburst’s magic split her skin, slowly tearing her throat. Starlight thought she was out of tears, but her crying renewed itself at that moment. This was it. She was going to die now, and all because she let her desire and magic get out of hoof. She didn't want this. She was too young to die! But there was nothing she could do. Starlight was powerless. She just sat and cried as she felt her pain rise, Sunburst’s magic tearing her flesh until her throat filled with blood. Starlight let out one last pained gurgle before Sunburst yanked her head with his magic, snapping her neck and tearing her head from her shoulders.

Starlight thought that was the end of it. She kept waiting for the pain to fade away, for her mind to be claimed by nothingness. But, instead, her pain blossomed and consumed her. She slowly opened her eyes, trying and failing to scream at what she saw.

Starlight looked down at her own, headless body being raped by her best friend. Sunburst grinned a vile, wicked grin before pulling his bloody cock from Starlight’s ruined cunt.

“You look confused, Starly,” laughed Sunburst, shaking Starlight’s severed head in his magical grasp. He lowered her head, forcing her to gaze into the bloody, pounded mincemeat that used to be her pussy. “You thought I was gonna let you die before you could feel me unload in your filly cunt? Not a chance!”

“H-how…?” croaked Starlight, her voice low and hoarse. She couldn’t believe this was happening, couldn’t even wrap her head around it.

“Simple magic, really. All I did was shove your soul into your skull when I ripped it from the rest of you. That sort of magic would come undone before most ponies could make much use of it, but, seeing as I’m raping you to death anyway, I’m sure it’ll be fine!” Sunburst smirked, then shoved Starlight’s muzzle forward and into her own pussy, forcing her to taste the blood and precum that coated her decimated labia. “Who’s magic is weak now, bitch?”

Starlight mumbled into her own cunt, some irrational part of her brain still begging for the mercy that she knew was unlikely to come. It was horrific, to be forced to eat your own bloody twat out, as a filly, no less. The situation was made none the better by the prodding Starlight felt at the base of her neck. She felt a long, hard, thick mass work its way up her esophagus, forcing its way into her mouth. It felt like she was throwing up, except that it was solid and throbbing slightly. Starlight clenched her jaw shut, hoping to somehow defy her rapist in her last moments, but this defiance was very short lived. The golden aura of Sunburst’s magic wrenched Starlight’s mouth open and, for good measure, yanked her teeth out of her gums. Sunburst dropped tooth after tooth onto the headless foal body, laughing at the delightful sensation of Starlight’s tight throat around his cock.

With his head pushing past Starlight’s bloody, toothless gums, Sunburst thrust back into the ruined cunt he had been enjoying earlier. This time, Starlight could see it as much as feel it. Somehow, despite being a severed head, she still felt the pain of Sunburst’s cock stretching the walls of her cunt. She still tasted his bloody cock in her mouth, and could feel her nose smash against her clit every time her friend hilted inside of her body.

Sunburst increased his pace, going deeper and faster with each stroke. Soon, he felt his cockhead slam against Starlight’s cervix, and yet still he went deeper, until he could feel himself pop through into the twitching, convulsing womb of a half-dead filly. Every thrust racked Starlight’s very being with pain, a pain made all the worse when Sunburst gripped the stumps that used to be her legs and tugged on them for more force and momentum. Starlight’s tears returned one last time, running a stream down her cheeks and mingling with the blood that dripped down to her chin.

Starlight heard a deep, bestial groan, then felt the cock in her throat and mouth swell before it erupted into rope after rope of hot, sticky cum into the ruined womb it was violating. Sunburst kept thrusting, packing in his load until he had deposited every last drop of his seed into Starlight’s cunt. He panted tiredly, pulling his cock free from Starlight’s head.

“There. A nice, hot, creamy load in your dead cunt, just like I promised,” said Sunburst. “I'm a man of my word, after all. Unlike some of us.” Sunburst smirked at Starlight’s slightly confused, but mostly agonized, grunt. “Did you really think I wouldn’t notice that Want It, Need It spell? It was such a shitty one, too! If I’m being honest with you, I probably could’ve prevented this, if I really wanted to.” Sunburst laughed derisively, rustling his dying friend’s mane. “But I couldn’t pass on the opportunity to rape your cute little cunt. Bye, bye, Starly.” Sunburst planted a kiss on Starlight’s forehead, then turned for the door.

Princess Twilight stood in the doorway, watching the mess unfold with a raised eyebrow. Sunburst froze in place, waiting for the alicorn to make the first move. Twilight let out a tired, dejected sigh, shaking her head.

“She was messing around with magic, wasn’t she?” she asked, mostly rhetorically.

“Yeah,” said Sunburst. “Age regression combined with Want It, Need It.”

Twilight sighed again, then began casting the various spells and charms she’d need to clean this up.

“You better hope I can fix this, or you owe me a new student.” Twilight slowly began to piece her student back together, thoroughly annoyed by the situation.

“Princess?”

“Yes, Sunburst?”

“Can I fuck her while you work?”

Twilight was quiet for a bit as she contemplated just how the hell this could have possibly gone as wrong as it had. She let out one last sigh, then shrugged.

“Fuck it. Have fun.”
