Twilight was an organized, coordinated mare: everything, always done to a schedule. Ponies could set their watches by her routine. Yesterday the little mare had reshelved the entire library in precisely forty-three minutes. Today she sat at her reading desk with a stack of three books. She was supposed to be reading at a pace that would finish all three of them by noon exactly.
Unfortunately for Twilight and her silly schedule, her reading desk just so happened to face a window looking out over the town square. A flash of pink caught her attention before she turned to stare out the window. She felt guilty for practically ogling her best friend every chance she got, but Pinkie made it so incredibly easy.
It was a little unfair for a mare like Twilight to move to a place like Ponyville. Purebred unicorns like her parents tended to stand around five feet or so in height, and fairly plump. Their magic was expressed through the mind and will, rather than the body.
Earth Ponies, on the other hand, expressed their magic through their bodies. When Twilight had first moved to Ponyville, she’d been immediately struck by how everypony literally towered over her. Standing a hair over sixteen feet tall, Pinkie was no exception.
The bubbly girl was massive and dressed freely, possibly even provocatively. Who could blame Twilight for staring when a gal with hips the unicorn couldn’t get her arms around jogged or skipped literally everywhere? A small flush rose to her cheeks at the memory of the first time Pinkie had picked her up for a back-breaking hug. Between the strength of the squeeze and her head being enveloped in a marshmallow hell, she hadn’t been able to breathe much, but she hadn’t minded it in the least.
She watched with bated breath as one hand slid between her own thick thighs. Nimble fingers slid beneath her panties and settled against her slowly plumping slit. Soft gasps issued from parted lips as she imagined larger, stronger fingers fondling her and plush lips against her own. Her motions steadily quickened, her hips rising and falling in her seat against her hand as her thumb delved to delicately stroke her joy-buzzer.
Her little moment was shattered by a sharp rapping at the door. She almost called for Spike, but didn’t trust her voice not to quiver. She remembered the dragon was out somewhere, anyway. A soft grumble issued from her lips as she straightened her clothing and washed her hands, before she took the stairs to the main level of the library three at a time. She liked living here. With the library having been built with Earth Pony giants in mind, it was rather like living in a dollhouse where everything was between two and three times too big.
She took a deep breath, standing before the door. Slowly she reached out, gingerly placing a hand on the knob…
Before she quite knew what was going on or what had happened, she was laid out on her back in a state of slight confusion. She glanced up… and up and up to see the sunny pink face of her giant friend above her, Pinkie practically straddling the smaller mare. She wore an almost uncharacteristic expression of worry and mild panic painted clearly across her pretty face.
“Pinkie, what are you doing here?”
“Sh-sh… Twilight you gotta help me!” The massive mare bounced up onto her hooves in one quick motion and slammed the door. The dazed unicorn got a brief glance of Pinkie’s vast tracts of land threatening to break free of her slightly undersized top, as the mare bent to pick her up and set her back on her hooves. She straightened again immediately and stared down at Twilight with a rather peculiar smile.
Twilight dusted herself off, still blushing heavily, as she trotted over to close and lock the door. Whatever Pinkie’s issue was, it sounded like it was actually serious. As opposed to her usual daily meltdown that she had baked cupcakes exactly ten seconds too long or… whatever it was Pinkie usually worried about.
“What’s this about, Pinkie Pie? Sit down and tell me about it. I’ll go make some tea.”
The huge pony plopped down on Twilight’s couch rather dramatically, with no small amount of pleasing and distracting jiggles and wobbles across her wonderfully plump form. Pinkie’s breasts alone threatened to bounce straight out of that shirt, and her soft tummy was left exposed above denim shorts cut so short that her cutie marks were clearly visible on her fat thighs.
Twilight trotted into the kitchen adjacent to the library proper, half-listening as she pulled a vast Earth-pony sized mug down from a cabinet. She couldn’t quite hear what Pinkie was saying, and was having a little difficulty paying attention as she moved about, loading up a tea tray with the kettle and accessories. She trotted back out with some difficulty and set the tray on the low coffee table before the deep-seated couch, pouring almost half a gallon of hot water into Pinkie’s cup.
“So with all that, I need your help with a spell, Twilight.”
Oh. It was something silly and inconsequential after all. Twilight cocked her hips before resting her hands on them with lips pursed.
“Pinkie, for the last time, I’m not turning your mane into cotton candy or… whatever you’re going to ask for this time.”
Pinkie let out an annoyed chuff, the smaller unicorn half-imagining steam coming from her nostrils. The big pony dumped no less than twelve sugar cubes and a full cup of milk into her tea, giving it a quick stir before taking a deep sip.
“No no Twilight, this is seeeerious. I need a uhm… erm…” Her voice dropped to an almost Fluttershy-like whisper. ”My contraceptive spell ran out and I need a new one.”
Twilight was on the verge of dismissing her yet again, before a word of that whisper stuck out in her mind. She noticed that Pinkie was holding her cup in one hand, the other tucked between those fat thighs as they clenched together. “Come again?”
“A-a contraceptive spell. It’s starting to get to be the season and… My old one is starting to wear thin and I have to wash my sheets and blankets and pajamas every morning and it’s getting super distracting at work and really hard to be around… certain ponies.”
Twilight was absolutely flabbergasted. She had been thinking naughty thoughts about Pinkie Pie earlier, but had brushed it off as just her overactive imagination. This was so far out of her league though, it made her a little nervous.
“Wait right here.” She held a hand out flat to indicate the pony should stay where she was, as she raced off to the stacks of the library to begin digging through books. Something in here must be able to give her some insight and allow her to take control of the situation.
She was about to give up before she found a tome and quickly flipped through the pages, speed-reading the contents. If she hadn’t worked herself up just before Pinkie showed up, she might not have had the courage to face this particular situation. She gulped as she slowly walked back to where her friend fidgeted on the sofa. She felt her cheeks flush and was very aware of the way her panties clung stickily to her labia.
She stood there, shyly staring at Pinkie as she rubbed her knuckles. She took a deep breath and closed her eyes, reaching out a hand with distractedly pursed lips.
“Here, let’s… go up to my bedroom for a little more privacy. I think I found a spell that matches what you’re asking for.”
Ignoring the hand offered to her, Pinkie set her cup down and launched herself to her hooves in one swift motion. Her long legs allowed her to take the steps four or five at a time, Twilight breaking into a trot to try to keep up. She chewed on her lower lip as she watched Pinkie’s pendulous rear sway and jiggle just over her head. When in her bedroom, she gestured for Pinkie to sit on the end of the bed, counting backwards from ten in an attempt to calm herself.
“The spell said that it wouldn’t work on a clothed pony, so,” Twilight swallowed heavily. “Y-you need to take your clothes off.”
Pinkie smirked softly and leaned back. She laced her fingers behind her neck, closing one eye and staring at Twilight as she folded one long leg over the other.
“You just want to see me naked, don’t you Twi?”
“What? N-No, the spell I found just only works if the magic doesn’t have to go through clothes first.”
”Well, alright…” She took a deep breath herself as her hands moved to her chest. Slowly, her large but dextrous fingers worked the buttons of her shirt open.
When she finally reached the last button and began to shrug out of her shirt, Twilight learned two things. Pinkie had much larger breasts than she’d previously thought, and the mare didn’t wear a bra. Her fat mammaries bounced free, wobbling and jiggling before the mare slid her hands across them to steady herself. Twilight could hear blood rushing in her ears as she took in the mare’s half-naked form before her.
Her friend had nearly spherical breasts just shy of three feet in diameter, capped with puffy inverted nipples roughly the size of one of Twilight’s teacups. The unicorn felt herself salivating, and shook her head to get a grip on herself. It wasn’t right to be thinking about one of her friends like this, imagining how that taut skin would feel under her tongue or how Pinkie would gasp and whimper.
Pinkie winked and smirked again as she unbuttoned and unzipped her shorts, pressing her thighs together and lifting her hooves as she slid them down towards her ankles. These were unceremoniously dumped aside on top of her discarded shirt, before the mare stood and turned to face away from Twilight. Her thumbs hooked in the waistband of her pretty pale-blue cotton panties and she bent over.
She tucked her knees just slightly, her tail flagging a bit as she wiggled her hips and began slowly sliding her underwear down off her lusciously plump posterior, wiggling it mere inches over Twilight’s nose. The small pony fidgeted, a soft gasp escaping parted lips as she caught the scent of her friend. Soft, slightly like vanilla, but intoxicatingly thick with arousal. When they hit her knees, they were simply allowed to drop the rest of the way to the floor.
Pinkie straightened back out and smirked softly over her shoulder, resting her hands on her hips. She slowly turned to face her friend, plopping back down on the bed and parting those thick thighs of hers. Between them rested something that aroused and frightened Twilight in equal measure.
A fat sheath resting atop a leathery sac stretched taut over orbs approaching beach ball girth.
Twilight gasped and blushed brilliantly, her hands clutching at the hem of her skirt and twisting the fabric shyly. As she watched, that sheath bulged and twitched, disgorging the blunt tip of Pinkie’s gray and pink mottled prick, her length easily as thick as one of Twilight’s calves. She watched, her inner thighs starting to darken with moisture as a pearly white dollop of sludge oozed sluggishly from Pinkie’s finger-thick urethra.
Twilight looked up at her friend’s muzzle, noting that the pink mare’s smirk had faltered slightly and she was breathing just as hard as Twilight was. The unicorn swallowed softly and chewed her lower lip. “C-Can I…” The studious mare paused for some time, unable to form the words.
“Twilight?”
“Can I touch it?” Her hand slowly raised, fingers splayed out slightly as she took a half step forward. “I-I’ve got to make a confession, Pinkie, and it’s going to be really awkward like this. I-I really like you, and I think you’re really pretty and…”
Pinkie gently laid a finger across Twilight’s lips. “I like you too, Twi. Why do you think I’m always coming to the library? Ever since you came to Ponyville I thought you were like, the greatest thing since parties and cake and cupcakes and party cupcakes.”
Now it was Twilight’s turn to look up with a rather sly grin of her own. She closed the distance, settling her palm on the hot bulk of Pinkie’s length, running a thumb across the blunt tip to gather up that oozy precum before darting her hand back to slowly lick it off.
“In that case, I don’t think either of us will be needing a spell. Natural methods should do… just fine.” Twilight congratulated herself for keeping her voice even and managing to sound cocky. Pinkie blushed and looked away, chewing one of those plump lips.
The small unicorn shuffled forward and settled on her knees between the mare’s strong legs. She took a deep breath as she peered upward, her hands encircling the thick length still swelling free of that sheath. She shyly opened her mouth, leaning to press the blunt tip against her lips. It took a little effort, but she managed to squeeze it inside her maw. The taste of Pinkie was overwhelming, flooding her senses as that length filled her mouth, straining her jaw and puffing her cheeks out.
Her cheeks drew inward as she began to suckle softly, pushing her head forward to try and fit more of that wonderful length into her mouth. Her scalp prickled as fingers softly laced through her mane. Her eyes closed, her heart thudding in her ears as Pinkie gasped and moaned softly. With a little help from the strong mare, that massive prick settled against the back of her throat, neither of them daring to go any further for fear of hurting the little mare.
Twilight peered up at Pinkie, slowly bobbing her plush lips over what could fit in her mouth, soft slurping sounds filling the air as her saliva coated that length. Her hands squeezed gently, applying more pressure as they slid down to Pinkie’s base. That pressure was released as she slowly slid her hands back up towards her tip, keeping the motions of her head in steady rhythm with her hands. After a few minutes of this she tugged herself free with a lewd pop, gasping for breath.
She stared up at Pinkie Pie, wiping her muzzle as she panted and drooled. She gently tugged on the mare’s hand to get her to stand, wriggling up to drape herself across the bed with her head hanging over the edge. She swallowed harshly, reaching to wrap her fingers around that length and pulling it closer to her. Her lips parted, her tongue tracing around that blunt tip as it filled her mouth with thick, juicy fluids.
“B-be gentle, Pinkie… I-I’ve practiced with toys but… You’re so big.”
Pinkie nodded mutely. Luckily, Twilight’s bed was rather tall, so she barely had to stoop. Now nearing full mast, Twilight got a good look at the sheer size of the mare. Edging close to five feet in length, and nearing ten inches in diameter at its widest point, Twilight was suddenly fearful beneath her arousal. She’d experimented with a toy just over five inches in diameter, had conditioned and enchanted her own body heavily in anticipation of ever fulfilling her deep-seated fetish for gigantic Earth dickmares, but Pinkie was even larger than that!
She closed her eyes as she felt Pinkie’s tip prod at her lips. She panted and whined, slurping and kissing against that flesh like a starving pony. This felt right. Pinkie felt right. “Please… I’ll let you know i-if I’m uncomfortable or need to breathe.”
“Okay, Twilight.” Pinkie’s voice was low, husky with emotion and lust, her frame trembling softly. She pressed firmly enough to just nestle her tip past those lips, shuddering and mewling softly as Twilight suckled. Her hands roamed to loosen her friend’s tie and unbutton her shirt. Her hands slid over the curve of the little mare’s breasts, running thumbs over her nipples. She giggled faintly as they stiffened under the contact and Twilight squirmed.
She just barely rocked her hips, her tip meeting the back of Twilight’s throat and sliding back to her lips. They eased into a gentle rhythm of Pinkie pumping her length and Twilight stroking along it as the big pony continued exploring her little friend’s body. She hummed happily as she slid off her skirt and tossed it into the growing pile of clothing, tugging at those panties. She brought them up to her snout and gave a little snuffle, her eyes lidding slightly before she tossed them aside too.
Broad fingertips found Twilight’s sensitive slit, her swollen labia winking to expose her fat clit. Twilight was momentarily afraid that Pinkie would dive in with her trademark enthusiasm and energy, but she merely traced the boundaries of her mons with smooth fingertips. Her hips moved a little more quickly, jostling Twilight’s frame on the bed. She didn’t indicate for Pinkie to stop, and indeed was moaning and almost purring between the loud gagging and choking noises of that length beginning to pry its way down her throat.
She giggled softly as Twilight’s jaw stretched and her throat bulged heavily, finding the small mare much more pliant than she’d imagined. She turned her attention away from the prize before her, clasping her hands against Twilight’s waist. She sorely wanted to get a mouthful of the pretty mare, but Twilight seemed to want her to focus on the task at hand more.
She shifted her weight slightly and bit a plump lip, holding Twilight steady as her motions became smoother and stronger, her battering ram of a cock cramming its way down her throat before disappearing beneath her collarbone.
Pinkie steadily withdrew, and the pink pony’s breath rasped softly. Hips flexed and thighs twitched in anticipation, until…
Twilight Sparkle awoke sharply, vaulting herself abruptly into a sitting position. She appraised her surroundings, finding herself in her own bed in the late-night or early-morning darkness of her quiet bedroom.
Such a strange dream, with a few… minor things wrong with it. She was troubled by her subconscious desire for one of her closest friends, but also in the way that it manifested. After all, a recent group trip to the spa had proved that Pinkie Pie was very much female.
Whereas Twilight was distinctly not.
