"So how's it coming?" asked Starlight Glimmer, rubbing the sleep from her eyes as she searched the kitchen cabinets for cereal bowls.

"Not great," said Twilight Sparkle. The chalkboard she was working on was covered top-to-bottom with the fruits of her overnight labors, and it was huge, even compared to Twilight's enormous body. Nearly the entire north wall of her bedchamber was covered by it. "The math is impossible."

"Impossible?" said Starlight. She found a box of Oaty Oats in a cabinet next to the kitchen's stove, and she flicked one of the stovetop's knobs experimentally, smiling in mild surprise as the corresponding burner flared to life. "I thought you were supposed to be pretty smart."

"I'm... experienced in putting my intelligence to good use," said Twilight. "But I mean it's literally impossible. What I'm trying to do, ultimately, is come up with a formula that lets me plug in data about this timeline and the normal one... and spits out a number that tells me which one is better." She groaned. "It's obviously a stupid idea, but how else am I going to be confident in my decision?"

"Just feel it out, maybe?" Starlight was a little distracted now, trying out all the kitchen appliances and finding them, to her surprise, to be real and functional. Starlight's new home - for the moment - was a dollhouse that Twilight Sparkle, Goddess of Pleasure, kept on her nightstand. And since Twilight was a giantess, the "dollhouse" was the size of a real house - and a princely one at that. And apparently it was fully functional. The downside, of course, was that each room only had three walls, with the fourth side totally exposed to the enormous bedroom that the dollhouse sat inside.

The dollhouse's existence raised some questions about the personal tastes of the old Twilight - the one who had risen to power in this timeline before this Twilight's mind had replaced hers. But the house had been unoccupied, so Starlight had moved in. It was a good place for Twilight to keep an eye on her, and since it wasn't literally a cage, Twilight kept getting to tell herself that she was a good person, unlike dastardly villain Starlight Glimmer.

"I can't just 'feel it out'," sighed Twilight. "This is a world full of people who worship me and want to... bathe in my cum or whatever. If I decide based on how I 'feel,' of course I'm going to prefer this timeline."

Starlight rolled her eyes. "Twilight, is there an expression for when something good comes your way, but you over-examine it to an unseemly degree?"

"No, I don't think so."

"Well, there should be," said Starlight, "Because that's what you're doing."

Twilight just kept staring at the chalkboard, shifting her body back and forth to look at different notes. Starlight kept her eyes on Twilight's giant purple ass, and she felt her cock stiffening. She'd decided to keep the dick that Twilight's magic had given her, although she'd had Twilight shrink it back down to the sensible, manageable length of two feet when fully erect. Having a cock longer than her body had felt amazing, especially since she'd used it to fuck the pussy of a sex goddess, but having it at this length was just more practical when it came to things like basic mobility.

"Let's simplify the problem," said Starlight. "What would be a dealbreaker for you? Is there any one thing that would prove to you that this timeline is better or worse?"

Twilight paused and set down her chalk. "My friends," she said. "If they... weren't in this timeline. If something happened to them. I would have to change it back."

"So start there!" Starlight said, "Track them down. Make sure they're all okay! If nothing else, it'll give you an excuse to leave your bedroom and actually see the world you're trying to assess. Weren't you going to see your dragon friend?"

"I suppose the 'Crystal Kingdom' is as good a place to start as any. Sure, let's go see Spike."

"You want me to go with you?" asked Starlight. "That enchantment you put on me makes it so I can barely do any magic. I'm not going to get up to any trouble while you're gone."

Twilight walked over to the dollhouse and crouched next to it, bringing her head level with the third-floor kitchen that Starlight was standing in. Starlight's heartbeat raced as Twilight's enormous face dominated her field of vision; her feelings about Twilight Sparkle were... complicated at the moment. Her nemesis, the princess of friendship, had become so big... and powerful... and gorgeous. So she leaned forward, taking her eyes off Twilight's face and focusing her attention on her tits. If Starlight opened her mouth wide, she was sure she'd be able to get her lips around one of those big, dark purple nipples...

"You're an extremely talented and resourceful magic user, Starlight," said Twilight. "If anyone can wriggle out of that enchantment, it's you. So I'm going to keep an eye on you."

Starlight frowned. "Fine," she said, scooping a handful of Oaty Oats out of the box and shoving them into her mouth. "Leff's oh, winceff."

She stood, unresisting, as Twilight reached into the dollhouse and grabbed her by the torso, forcing Starlight's erect cock up between her tits as the giant fingers curled around her. The soft skin of Twilight's hands against her body made her whimper, as an unexpected wave of arousal hit her. Starlight's hatred of Twilight, her indignation at being defeated, was still burning in her chest - but now her nemesis was a literal goddess whose power had altered her body, rendered her helpless, and given her the best orgasm of her life. Being so powerless should have made Starlight want to scream or cry... but instead it was making her cunt overflow and drip down her thighs, and making her cock bubble over with precum, spilling over the edge of her cockhead and dribbling down Twilight's fingers.

Twilight laughed as Starlight Glimmer's arousal coated her hand. "That's gross, little lady."

Starlight swallowed her mouthful of cereal and chuckled. "You better get over your squeamishness, princess. I'm guessing the ponies of this world don't expect their 'Goddess of Pleasure' to get squicked out by a little cum."

Twilight harumphed. "Yeah, you're right."

At the top of the castle's highest tower, guards of every pony race stood at attention as their goddess flexed her wings. She hadn't given it much thought before this moment, but Twilight was glad that her ascendancy to "godhood" had apparently come with a set of wings. She'd just gotten used to the things, and she'd have had to adjust all over again if her body didn't have them in this timeline.

Plus, they were a convenient way to get around. Twilight bent at the knee, then she pushed off, flapping her enormous wings hard enough to stagger her guards and send their oversized naughty bits wobbling.

As she took to the sky, Twilight spared a quick look backwards at her castle, a massive structure that was colored the same purple as Twilight's own fur. She only now realized that it was built atop the mountain that overlooked Canterlot, overshadowing the former princesses' home in both size and altitude.

Her first impression was that the castle was surprisingly tasteful, given the overt sexuality that seemed to be the hallmark of the Goddess of Pleasure's rule. But a second glance, just before it passed out of sight, made her suspect that phallic and yonic imagery was liberally incorporated into the architecture. She'd have to take a closer look when she returned.

The north wind whipped past her body as she flew towards the Crystal Kingdom. It seemed to linger over the sensitive parts of her body, caressing her nipples, flowing through the crack of her ass, and eddying around her cock to skim her pussy. She felt her dick growing and stiffening, and wetness gathered in her cunt. She bit her lip, increasingly sure that she wouldn't be able to hold herself back for the entire flight to the northern territory.

But then, did she need to hold herself back? She was the Goddess of Pleasure, after all. The living deity of Equestria. She didn't quite know what that entailed, but it probably meant she was permitted - even expected - to cum anywhere and anytime.

Thick drops of pussy juice began to speckle the countryside. Then a drizzle, then a downpour, darkening the earth with musky moisture. Her flight was approaching a town, not much bugger than Ponyville, whose houses sat in the shadow of a mountain range. Tiny shapes moved through its streets, but a few seemed to stop moving... then more...

Twilight cast an optical enhancement spell and mentally adjusted its focus, zooming in on the town below. The ponies were indeed stopped in the streets, craning their necks upward, looking right at her. Arms outstretched, mouths open...

Oh shit. They wanted it. They wanted a rain of pussy juice, a thick glaze of their goddess' cum. The thought made her even hornier, and her cunt pulsed with building heat, even as the chilly wind whipped at it. Twilight gasped, tiny yelps escaping her throat as her body worked itself to climax. Her wings stiffened and her body seized as she came, and each powerful throb in her core sent a forceful squirt down into the town.

The fluid splattered against walls, flowed through streets, and landed on the outstretched tongues of the ponies of the town. Through her enhanced eyes, Twilight saw them begin to touch themselves, then each other. Ponies were kissing, groping, mares on stallions on stallions on mares, dicks growing hard between the legs of males and females alike. Through the crisscrossing streets, cocks plunged into holes and ballsacks slapped against bare skin. Pussies dripping with juice found ready, eager tongues.

And above it all, Twilight's own climax was pumping its way through her body, making her balls tighten, making cum climb through the length of her stallionhood. It built for what seemed like forever, her own body teasing her mercilessly. And then she came again, shooting a thick, heavy rope of divine jizz that splattered at the edge of the town. Reaching down an arm, Twilight grabbed her shaft and corrected her aim, pointing the head of her cock at the town square. The next load of cum hit dead center - thanks in part to her optical enhancement spell - and splashed beautifully, filling the streets, overturning fruit stands, dislodging roof tiles as it splattered and flowed. She adjusted the angle of her cock with each throb, glazing the town thoroughly with her thick, sticky love.

And the town loved her right back. She could feel it. The collective pleasure of the town's orgy hit her like the warmth of a roaring hearth. Like spiced hot cocoa, sweet and soothing from her tongue to her throat to her belly. So this was the magic of pleasure. Twilight wasn't prepared to say it was better than the magic of friendship, but it was easy to see how it could have united an empire under her rule.

Twilight felt a squirming in her crotch. She'd all but forgotten about Starlight Glimmer, who was cozily tucked inside a pair of tight, stretchy black shorts. Actually, the garment was more of a sling, designed to hug Twilight's ballsack while leaving her cock and pussy completely exposed. Celestia and Luna had explained that Moondancer habitually traveled inside the garment when Twilight was flying, and Starlight had raised no objections to being carried in the same way. Twilight still hadn't quite figured out how Starlight felt about her - it seemed like she should be holding a grudge, but she had been surprisingly agreeable ever since the incident in the throne room. In any case, the little troublemaker seemed to be enjoying herself, energetically wriggling against Twilight's massive nuts.

As Twilight left the town behind her, she felt sticky liquid warmth fill her shorts, and Starlight's body breathed a satisfied sigh and went limp. Twilight smiled, pleased that Starlight was having some fun down there.

At the edge of the Crystal Kingdom, Twilight landed with an earth-shaking thud and plucked Starlight's sodden, sticky body out of her shorts. The little pony was still limp, almost boneless, but Twilight felt her chest rise and fall with strong breaths as she gently set her down with thumb and forefinger.

"How are you feeling, Starlight?" asked Twilight. Starlight barely responded, only mumbling dreamily and stroking her own skin. "Yikes," said Twilight, "Was sustained, intimate contact with the naughty bits of a Goddess too much for your mortal mind?" Twilight took her soft mumble as a "yes."

With an amused sigh, Twilight cast a cleaning spell on Starlight's body. Starlight, no longer soaked in Twilight's divine sexual musk, fluttered her eyes sleepily and sat up. "We're here?"

"We're here," said Twilight. "I wasn't sure if there would be a place for me to land near the castle, so we're going to take a stroll through the town." She cast Force Cushion on herself, a more complex variation on the Force Armor spell. Force Cushion was usually cast during sparring exercises, to allow combatants to strike each other without doing harm. Less commonly, it was cast on dangerous beasts, to prevent them from causing damage during transport. It consumed a lot of energy when cast on large or fast-moving targets, but being a goddess meant Twilight had power to spare.

Once the spell was cast, Twilight picked up Starlight and took an experimental step onto the Crystal Kingdom's streets. The crystal pavement didn't crack under her weight, so she took another step, more confidently, heading towards the crystal castle that dominated the skyline. As she walked, ponies began to filter out of the buildings, their shining crystal bodies gleaming in the sunlight. She couldn't make out anything they were saying, but they didn't seem to want anything from her - they just came to see their goddess, brushing their tiny hands against her hooves and stroking themselves. One stallion lay himself on the ground in Twilight's path, and she hesitated. But the Force Cushion seemed to be working fine, so she brought her hoof down on his little body. The spell spared him from the full force of the giantess' weight, but his body compressed slightly - which was presumably what he wanted. Twilight giggled as the stallion's cum splattered against her hoof and puddled on the ground. She lifted her hoof, leaving a sticky and satisfied stallion on the pavement behind her, and continued on towards the castle.

The crystal ponies guarding the palace stood at attention as she approached, their cocks and pussies leaking through their armor as they beheld Twilight's magnificence. She eyed the palace's front gate, sizing it up, and set Starlight down as she prepared herself to cast another spell.

Celestia and Luna had explained some of the basics of Goddess Twilight's life, including spells she used commonly. As a goddess, she had the right to demand that ponies leave their homes to meet her, standing reverently at her hooves as she looked down from on high. But when entering a normal-sized structure was preferable - or unavoidable - she had a spell to compress her body to a smaller size.

The castle grew in front of her, rising into the sky, as her body scaled down. Instinctively, she tried to reach her normal height, but when she hit about ten feet, she found it difficult to shrink any further. It was like trying to close an overstuffed suitcase - or maybe "stuffing an erect cock into tight pants" would be a better comparison. Every part of her wanted to be bigger, and her naughty bits were no exception. The compression spell put pressure on then, and if she tried to squeeze them any smaller, she was worried she'd lose control. At any rate, ten feet was fine for most purposes. She'd duck under doorframes when she needed to.

Twilight hadn't sent word of her arrival, but she was hard to ignore, and a lookout must have informed "King Spike" and "Queen Rarity" that she was coming. The palace doors opened before her, and the two of them stood within.

Rarity was the first to approach Twilight. She was wearing a gown of so thin and diaphanous that it didn't conceal an inch of her nudity, merely colored it with translucent layers of blue and green. "My Goddess!" she exclaimed, "Your presence is a delightful surprise. Might my husband and I tempt you with our bodies? I believe I speak for both of us when I say that we are ready and eager to service you."

Twilight's marehood and stallionhood were united in their enthusiasm. Her pussy dripped arousal down her legs, and her cock rose and fattened, dripping precum onto the crystal pathway. Twilight had always admired Rarity's beauty, but she'd never seen her friend like this. With some effort, she declined. "Perhaps later," she said. "I and my..." she stumbled for a way to describe Starlight. "...Student would like to speak privately with Spike."

"Certainly!" said Rarity. "Spike, my dear, let us take the goddess and her student to the meeting room. I shall wait outside."

As Starlight took a seat, Twilight scanned the soundproofing enchantment around the edges of the meeting room. She didn't want to keep secrets from her friends, but it seemed like the safer choice for now.

She turned her eyes to Spike. He hadn't spoken on the walk to the meeting room, and he seemed nervous. Twilight had a guess as to why - he was in an unfamiliar timeline, unsure if the Twilight Sparkle he was looking at was an old friend or a potentially wrathful goddess.

"Spike," she said. "It's me! Your Twilight!" Spike sighed with relief. "You look good, by the way. Is your body a little more... mature?"

Back in the original timeline, Twilight had done some reading on the care and raising of baby dragons. The physical maturity of a dragon's body was more strongly influenced by behavior than by time, which created unique challenges for their caretakers. Totally indulging a dragon's greed resulted in dangerously fast maturation, but careful management of their behavior permitted them to grow at a normal pace. In the original timeline, Spike had been alive for nineteen years, and his physical maturity matched his age. In this timeline, his body seemed a couple years older.

"Yeah," said Spike. "It's a bit of an adjustment, but..." He looked Twilight's body up and down, from her hooves to her enormous, erect cock to her ten-foot-high head. "Looks like you have even more changes to get used to."

Twilight chuckled. "You know, one of the dragon-raising books suggested that I keep you in a childlike state permanently. You'd have a lot more to adjust to if I'd done that. Can you imagine?" Twilight and Spike shared a laugh at the thought of such an absurd scenario.

"Well, this is all of us," said Starlight, leaning back in her chair. "The time-displaced trio. Does this change your assessment of this timeline at all, princess?"

"What's she doing here?" asked Spike. "Isn't she bad news?" Starlight scoffed.

Twilight shrugged. "I'm keeping an eye on her. And we're trying to figure out if this timeline is any good, or if it's better to go back in time and change things back to normal. Any thoughts?"

"Hrm," muttered Spike, "Hard to say. I haven't seen much outside of the castle, but things seem pretty peaceful... and I'm married to Rarity, and I'm a king... and you're a goddess, whatever that means."

"I'm still figuring that out too," sighed Twilight. "But... if all our friends are okay, you'd be okay with staying in this world?"

"I guess so, yeah."

"Great!" said Twilight. "It sounds like we're in agreement, then. I'm going to track down the rest of the girls, and..." she gestured at the opulence of the crystal walls around them, "You can stay here, or come with me if you like."

"I think I'll stay for now," said Spike. "I have a marriage to figure out."

"What needs figuring out?"

Spike put his head in his hands. "I'm not the dragon she married," he said. "I mean, I'm literally a different person, and she doesn't know. I have to be honest with her, if we're staying in this timeline. I just don't know how."

"Mind if I help?" asked Twilight. "I want to rebuild my friendship with Rarity. We may as well talk to her together."

"Thanks," said Spike. "I think that would help."

"My goodness," said Rarity. She took a thoughtful sip of her tea, then placed it down on the small table next to her throne. "And the original Spike - er, the one from this 'timeline,' as you put it... is truly gone?"

"I'm afraid so," said Twilight. "I can't think of a way it would be possible to bring him back. Starlight, what do you think?"

Starlight hadn't been giving the conversation her full attention; she'd tuned out after the second time Twilight had referred to her as a "villain." She'd mostly just been ogling the array of gorgeous bodies around her. Rarity's body was a marvel of curves, her round tits and wide hips totally exposed by her transparent dress. Spike was a handsome specimen too, with lean muscle beneath gleaming dragon scales. And Twilight...

Twilight's cock had been hard and dripping since they'd seen Rarity, and the sight of her twitching shaft made Starlight's cunt ache. Goddess-sized Twilight had a cock bigger than Starlight's entire body, but at this size... well, it would probably still take some magic to fit Twilight's massive member into her pussy, but Starlight was sure that the Goddess of Pleasure could pull that off.

"Er, yes," said Starlight. "I mean, no, I don't think there's a way to recover a consciousness that's been displaced in this manner. I really hadn't considered the possibility when I altered Starswirl's spell."

"Rarity," pleaded Spike, "I know this is hard to accept, but I loved you in the old timeline and I love you now. I think we're meant to be together, and I want to prove it to you."

Rarity sighed. "If I can accept that my goddess is a different person now, I suppose I can accept the same of my husband."

Twilight chuckled. "I'd rather be your friend than your goddess, Rarity."

Rarity rubbed her chin. "Well, if we're friends, your wor- er, Twilight... could you favor Spike and me with a bit of magic? Something to help us... get to know each other?"

"I think I know just the spell," said Twilight, as a swirling, sensual glow gathered around her horn. In her overnight research of this new timeline, she'd discovered a document of new spells, seemingly developed in collaboration between Goddess Twilight and Moondancer. One such spell had been specifically designed for couples: it scanned the sexual fantasies of the spell's targets, discovered what fantasies they shared, and brought their desires to life. If Rarity and Spike wanted to become closer, this was their best bet.

The glow faded from Twilight's horn, and the spell swirled around the bodies of Spike and Rarity, who regarded the swirling lavender magic with interest. The magic made tighter and tighter circles around their bodies, until it vanished into their skin. Twilight watched Spike, waiting for something to change - a transformation, or a shift in behavior. But out of the corner of her eye, she saw Rarity begin to change instead.

Rarity moaned softly as her limbs lengthened and her skin began to shimmer. Her head rose higher and higher, overtaking Twilight's ten-foot stature. She raised her fingers to her face and watched them become long and slender, claw-like. She swished her tail experimentally as it grew longer, and she ran a forked tongue along her sharp, gleaming teeth.

"Oh, this is new," said Rarity. "Spike, darling, I think I make a lovely dragon. Do you agree?"

Spike's jaw was practically on the floor. "You're... amazing," he said, staring up at her. He'd been slightly taller than her when she was a pony, but now she was more than twice his height.

"I'm glad you like it," said Rarity. "I've always wondered what it would be like, and now... oh, oh!" Her mouth hung open as another unexpected change came over her. Her hips rolled forward, and from just above her dragon pussy, a cock erupted, thick and long and instantly hard.

"Ooh," said Twilight excitedly, stroking her own shaft. "So you like this sort of thing, huh, Spike?"

Spike looked down, avoiding Twilight's gaze. "Well... I never really thought about it before, but... in this timeline, there's a lot of mares with penises, and... well, I got a little curious."

"You don't have to explain yourself, Spikey-wikey," said Rarity. The talons of her feet clakced on the crystalline floor as she advanced toward Spike. "Just lift that darling tail of yours and show me your sweet little backdoor."

Spike lifted his tail, but cast a nervous glance at Twilight. "Is she going to fit?" he asked. "That thing's almost as thick as me..."

"It'll fit," said Twilight confidently. "That's the magic of pleasure. Now have a little courage and let your wife fuck your ass."

Spike laughed. "All right," he said. "Rarity? Give it to me, sweetie. I want it." He turned his ass towards Rarity, tail in the air.

"Certainly," said Rarity, pointing her cock down at Spike's backside, "What kind of wife would I be if I didn't fuck my adorable little husband's ass when he asked me to?" She prodded Spike's cheeks with the head of her cock, smearing a trail of precum along his scales. "What kind of wife would tease her beloved husband's butt with her thick, long cock?" Spike groaned, and Rarity pressed her cock against his puckered hole. "I could never be so cruel."

She thrust downward - the angle was awkward, but Twilight's magic made Spike's ass easy to penetrate. He opened right up, accepting the first twelve inches of Rarity's cock with no resistance. Twilight could see Spike's body stretching, widening. His belly grew with the shape of Rarity's cock, and he rubbed his claws over his chest, feeling his wife's shaft through his scales.

Rarity picked Spike up, his body still impaled on her cock, and set him down on his tall crystal throne. With his body slumped in the chair and his ass as the edge of the seat, he was at the perfect height for Rarity. She pulled their bodies closer together, sinking her cock deeper into his ass. "Oh, darling," she said, her breath catching in her throat, "Your ass is just heavenly. Twilight, dear, I can't thank you enough. This is wonderful."

Twilight nodded, stroking her shaft with one hand and trying to give her balls and pussy equal attenion with the other. Fuck, why couldn't the goddess ascension have given her an extra set of arms? That seemed like a useful thing for a deity to have...

She leaned her head down and slipped the tip of her cock into her mouth, lapping at her own dripping precum and massaging the flared head with her lips. With her cock taken care of, she slipped one hand into her pussy and kneaded her heavy nutsack with the other, keeping her eyes locked on Spike and Rarity. When Spike had been crushing on Rarity in the old timeline, Twilight had imagined what their relationship would be like... but she never imagined that she'd ever witness something like this.

Starlight stepped into Twilight's field of vision, looking a little annoyed. "You'd rather suck yourself off than do anything with me, huh?" Twilight raised her eyebrows, prompting Starlight to continue. Starlight lifted her ballsack, exposing the dripping pussy underneath. "I haven't gotten my pussy fucked since coming to Pleasure World," she said, "And that seems unfair, even if I am your prisoner."

Twilight wanted to dispute her use of the word "prisoner," but the sight of Starlight's sopping cunt filled her mind with other priorities. She popped her dick out of her mouth and leaned back against the wall of the throne room, pointing her cock straight up. Starlight just stared for a moment. Even slumped against the wall, Twilight's body was imposingly massive, and her three-foot cock was intimidating - but irresistible.

Starlight cautiously stepped onto Twilight's abdomen, and Twilight cupped her hands under Starlight's ass, lifting her up and positioning her on top of her dick. Starlight's pussy pulsed as their junk made contact, and she felt herself widening as Twilight lowered her down. Like Spike, her chest distended with the shape of her partner's cock as she was speared deeper and deeper. She felt Twilight's shaft filling her, rising up through her body. The feeling of being stretched wasn't painful, but it was somehow excruciating, almost too much sensation for her body to bear.

Spike was having a similar experience - Rarity was sliding in and out of him, moving her wide, scaly hips in smooth motions. The strength of her huge dragon body made it easy to enter Spike's ass, and she plunged her cock into him with building speed, making his body stretch and shrink with each enormous entry.

"Oh Spikey," Rarity said, "Isn't this marvelous? I feel so close to you, darling. I'm inside you, I'm so deep. It feels so good to fill you up like this, my tight little husband." Spike didn't respond - maybe couldn't respond, considering how hard and deep he was being fucked. His own cock was upright, spitting precum with each twich, barely holding itself back.

Starlight did her best to ride Twilight's cock, but there was so much dick inside her, making her weak in the knees, that she could barely move her body. Twilight, growing impatient with Starlight's sluggishness, put her hands on both sides of Starlight's torso, sinking her huge fingers into her soft skin, and plunged her downward. Starlight let out a broken yelp as a full foot of Twilight's shaft entered her body, distending her torso all the way up to her tits. Starlight's cock shook with the impact, and her precum flew, splattering onto Twilight's amazonian tits.

"Do you like it?" asked Twilight, grinning at Starlight's helpless, moaning face. "You like being fucked by your goddess?" Starlight made a pouting face and turned away, and Twilight lifted the smaller pony's body up and slammed it back down onto her shaft. "You act like you don't like me, Starlight, but you don't pass up an opportunity to get fucked by me. I wonder if you like being my helpless little plaything... My cute little cocksleeve." She brought Starlight's body up and down again, then again, fucking her faster and faster. "How'd you like to be my official cockwarmer? You need a place in this new timeline, Starlight. You need a purpose. Maybe you can - unf - devote yourself to servicing my big... divine... cock."

In spite of herself, Starlight felt herself being driven over the edge by Twilight's words and the feeling of the giant cock inside her. She didn't want anything other than this. She never wanted to spend a moment away from the marecock that was filling her body. Her pussy clenched, pulsing around Twilight's shaft, and she climaxed. Jolt after jolt rocked her body as her pussy throbbed, and the feeling shot through her cock, making her shoot her thick, pearly load onto Twilight's gigantic bosom.

Hearing Starlight yell out, Rarity looked over her shoulder, craning her slender dragon neck to watch Starlight cumming. "Oh, spikey-wikey," she said, plunging her cock into his ass again, "It looks like Twilight's student is climaxing. Will you do the same for me, Spike? Will you cum for me?" Spike just groaned, still unable to speak. "I want to see it," cooed Rarity, "I want to see your cute little cock shoot. Show me how much you like getting fucked, Spikey. Cum for me."

Spike's head rolled back, and he let out a helpless, rising groan as Rarity slid in and out of him, hilting her cock in his belly, bulging his scaly body with every thrust. His cock jumped, and his load shot like a rocket, hitting the underside of Rarity's chin, then her scaly tits, then coating his own body with each diminishing pump of his cock. His ass clenched around Rarity's cock, and she came inside him, making his body bulge even more. Unlike Rarity, Spike's body hadn't been changed visibly by Twilight's spell, but it was clear now that the spell had given his body the ability to stretch far beyond what would normally be possible. His body ballooned as Rarity pumped cum into him; the load of a twelve-foot-tall dragon was impressive, and the influence of the Goddess of Pleasure's magic only increased its volume. Spike's body fattened tremendously, his belly overflowing the sides of the throne he was slumped onto. Rarity placed a loving hand onto his belly, feeling her liquid affection fill her husband bigger and bigger.

Twilight had held herself back for a long time, but now there was just too much stimulus - the feeling of Starlight's spasming cunt embracing her cock, the sensation of Starlight's hot load hitting her tits, and the sight of Rarity filling Spike with more and more dragon jizz... Twilight couldn't hold back anymore. But it wasn't just an orgasm that Twilight felt coming - it was her whole body pushing back against the compression spell that she'd used to reduce her size.

She lifted Starlight off her twitching cock and set her down on the floor of the throne room. And then she relaxed the compression spell, letting her body burst into hugeness, her limbs growing and thickening with such speed that she feared she'd crack the ceiling of the throne room. Within seconds, she towered over everyone, even Rarity, and her massive body shuddered as her cock and her pussy found release. Her pussy flooded itself, spilling over a thick puddle of juices that quickly spread and soaked the throne room's long carpet.

Her cock shot a long, thick rope of cum, splattering the far wall and glazing Spike and Rarity with an inch-thick layer of jizz. Her next pump of cum shot just as far, coating more of the throne room, ruining tapestries and marking the seat of royal power with the musky love of the Goddess. Her body was still growing, and she regained control of herself just in time to keep her hooves from bursting through the far wall. Her head was nearly brushing the ceiling, and her body occupied most of the floor space of the throne room. Her cock was still shooting, coating the floor with a deepening pool of cum.

The other three - Starlight, Rarity, and Spike - awoke from orgasmic bliss and wiped a layer of cum from their faces. Starlight, pinned between Twilight's giant asscheek and the throne room's wall, wriggled free and looked up at Twilight. "Always have to upstage everyone, don't you, princess?" she said, giving Twilight a sour look.

"Why do you call her 'princess'?" asked Rarity, cocking her head.

Starlight sighed. "Long story," she said.

Rarity smiled. "Well, I'd love to hear it," she said. She picked up Spike, holding his bloated body to her scaly chest. "If the two of you don't need to leave right away, I'd love to hear all about this other 'timeline.' And... if it's all right, I wouldn't mind keeping this dragon body... and this cock... for the time being."

"Fine by me," said Spike, smiling placidly.

"Yes," gasped Twilight, her cock still bubbling over with the last of her climax. "I can... make the spell... last longer... and..." she took a few breaths, and smiled. "I'd love to stick around for a while and... get to know you better."
