Lightning crackled in the sky as Trixie and Twilight Sparkle stumbled into the Golden Oak Library, the two nearly falling over each other in a concerted effort to escape the pouring rain. The windows shook as thunder boomed outside, and Trixie found herself gasping for breath as the warm, slightly musty air of the library welcomed them in. Beside her, Twilight shuddered with chill, and her horn sparked with magic as the door slammed shut behind them.
Trixie wheezed, and then, funnily enough, began to giggle. "Now that," she said, wrapping an arm around Twilight’s shoulder, "is a proper storm!" She gave her marefriend’s upper arm a little squeeze and felt Twilight’s damp shirt squelch beneath her fingertips. Twilight’s figure, curved, though slender at the middle, fit into Trixie’s side like a puzzle piece.
"Oh, y-yes." Twilight's own giggle was softer, and slightly higher-pitched. As Trixie turned to face her, she realized with alarm that she could hear Twilight's teeth chattering. "V-very—very wet."
Trixie blinked at her quivering marefriend. The both of them had gotten wet, but Twilight especially had gotten drenched. She simply didn't have Trixie's road experience. The poor mare had been caught in the sudden downpour like a rabbit in a monsoon, and not an inch of her clothing was dry. That included, Trixie noted, with a small flicker of guilty approval, the top half of her blouse, which had been rendered more see-through than opaque.
Trixie's clothing was more weatherproof in the first place, out of simple habit. Twilight, though…
Drenched with enough water to drown a yak, Twilight's white shirt had been rendered all but transparent by this point, showing the plump heft of her large, pert breasts and her fat, perky nipples. Those nipples were completely stiff, Trixie noted, with a delicious little shiver that seemed to warm the two of them up.
It didn't take long, though, to notice that Trixie herself was actually shivering as well. "Goodness," Trixie scoffed, and patted Twilight's hip with a wavering hand. "The two of us are absolutely soaked! Unbefitting for such a pair of talented mages."
Twilight caught Trixie's eye and smiled weakly. "M-maybe we should dry off?" She hugged her hands closer to her chest, her forearms pushing her big, squeezable tits a little bit further forward. It was an appreciable effort for Trixie not to lick her lips at the sight of such pert, taut spheres.
Time to get your mind on being the Wise and Wonderful marefriend, Lulamoon, she told herself. Out loud, she nodded and said, "Oh, yes." Trixie frowned, glancing around the foyer. Then she smiled. "Come," she commanded, beckoning Twilight into the sitting room.
A quick flash of telekinesis placed two logs into the fireplace; a conjuration of flame set them burning and crackling nicely. Trixie decided to set a good example, and so was the first to tuck both hands under the hem of her shirt, long fingernails pricking against the fabric as she lifted her own shift up and over her head. Twilight stared blankly as Trixie disrobed, then made an understanding "o" with her mouth as she watched Trixie conjure up a stand to sling her wet clothes over.
"Now you," Trixie said, gesturing as elegantly as her old mentor on the road had. Pervy, but he'd been right then and she was right now.
Twilight coughed. "Erm—"
Trixie rolled her eyes and fixed the "Hero of Equestria" with a heckler-freezing stare. Academics! So repressed. "Clothes. Off."
Twilight sighed, but did as she was told. Moments later, she gazed at Trixie with a quirk in her eyebrow, one eyebrow cocked. Removing her wet clothes, though, left Twilight still shivering beside the fireplace, with nothing more than an overstuffed, see-through bra and a pair of very overstretched panties bulging around her crotch. Very nicely stretched indeed, Trixie thought, covetously eyeing the curved bend of purple flesh filling out her marefriend's clean black panties. Twilight might have been slender, but her build was wonderfully top-heavy, both at the top of her chest and at the top of her legs.
The cold's chill brought out her whimsy. You've saved your marefriend from certain doom, Lulamoon, Trixie thought. What will your next astounding trick be?
Not a hard choice. Practical, honestly "On the couch," Trixie ordered. She flicked one long fingernail in the direction of the sofa, which she levitated closer with a grunt of effort. A smile curled her lips, and she gave Twilight a wink. "Lay down." Another shimmer of magic levitated a blanket from a shelf to the side of the room.
"O-kay." Twilight eyed the warm blanket with no small amount of gratitude, and let her shivering hands fall from her waist before plopping down onto the couch. Trixie's grin widened, and she moved to push down the band of her own wet pants. At this point, though, they were wet with more than just water—as the hem shifted across the top of her crotch, she had to stifle a soft moan, the taut rubber flicking tantalizingly against her hard, throbbing bulge.
Trixie sat down on the side of the couch beside Twilight’s shoulder, her rump pushing Twilight to press a little more closely against the far vertical cushion. Grinning, Trixie then slung her far, well-toned leg across Twilight's torso, finishing only when she had mounted her marefriend with both knees clasped around Twilight’s waist.
With a grunt of satisfaction, Trixie lowered herself down, licking her lips lasciviously as her taut hips ground against Twilight's. Below her, the shivering Twilight groaned softly, her chattering teeth pausing as Trixie's warm, supple flesh moved against her own.
The blanket settled over them with a soft thwump, and Trixie savored the warmth it brought. She'd been cold too, she had to admit—though from the moment she'd laid eyes on her marefriend's quivering, stiff nipples, her heart—and her crotch had been hotter than a furnace.
A happy coo passed from Twilight's lips, and Trixie smiled as she carefully let her weight press harder against her marefriend's prone form. Trixie exhaled, her chest relaxing as her own bra-held boobs pressed against Twilight's, stroking back and forth with each breath.
Twilight shuddered, shivers chased away with intimate warmth. "Mm," she murmured. She giggled. "Toasty."
"Perfect," Trixie purred, moving across her marefriend with a proprietary slink. She shifted her weight, grinding her hips—and bulge—against Twilight's own. Beneath her, Twilight sucked in a breath, a whimpering little moan coming from her lips a moment later. A grinning Trixie saw her opening and took it; a spark of magic unbuckled both of their bras, casting the wet cotton linen off to the side and letting both mares' bountiful busts spring into mutual embrace.
Twilight groaned as Trixie's stiff nips poked and stroked against her own, then chuckled. "Wanted to warm me up yourself, huh?"
"I could think of no better plan," Trixie said loftily. She felt Twilight's stiffening erection throb against her own and snickered. Already, both of their heavy stallionhoods were poking up out from the lace of their panties, lengthy shafts frotting together as hot, milky pre streamed between their girths. Her own panties, she could already feel growing taut around her full, hefty balls; of the two of them, Trixie's member had always been larger, to her pride...but Twilight's lovely breasts, great, wonderful orbs of supple flesh that they were, were a good three cup sizes bigger than Trixie's, and so wonderfully warm as well.
Well. Warm now that she’d heated things up a bit. Trixie hummed to herself as she moved her manicured hands up Twilight's soft, curvy belly. The thick blanket rasped above Trixie’s shoulder blades, the weighty fabric just hinting at the curves of her luscious, showmare's ass. The two mares grunted together, eyelids fluttering shut as Trixie's engorged cock glided downward across Twilight's own length. Its passaged was slickened by pre, its lengthy journey made all the longer and all the juicier by Trixie's two-foot length and Twilight's own fifteen inches.
But Trixie found the end eventually, having pulled back her big rump so far that Twilight's torso was nearly totally uncovered. Great, heaving tits the size of her head bobbed up and down with Twilight's breath as Trixie rocked her hips back, Trixie's own fist-sized cum-spheres smooshing gently against the insides of her thighs. Grinning, Trixie met Twilight's eyes and winked.
"Another part of me is still a bit cold," Trixie murmured, pouting. "Will you let me warm him up a little?"
Twilight chuckled, and patted her belly. She gave Trixie an adorably imploring pout. Pleased, Trixie noted she wasn't shivering anymore, either, Twilight stretched beneath the showmare and quivered her lower lip as she said, "So long as you leave me a nice hot-'water' bottle when he's done."
"Oh, but of course," Trixie murmured, touching a hand to her cleavage. She added, as if offended, "Trixie could do no less!"
She swung her weight forward in an agile, athletic motion, steadying herself against the couch cushions. Twilight grunted beneath her, stretching well-curved thighs out to either side as the girth of Trixie's flare pressed against her marehood—and then moaned as Trixie pushed her way through, grinding her throbbing shaft against Twilight's dangling sack as she enthusiastically welcomed the visitor inside.
Trixie smiled. "And Trixie is always happy to provide.”
Groaning and stretching her neck out, Twilight squirmed happily as inch after inch of Trixie's thick, throbbing rod buried themselves inside of her. Twilight's own well-rounded nuts, easily the size of small apples, draped lovingly over Trixie's pre-lubed shaft as it pushed its way inside their owner's cunt. By now, the couch cushion below was stained with their hot, dripping juices, but neither Trixie nor Twilight cared. It was simply more heat for the moment.
With a final, triumphant grunt, Trixie shoved her girthy cock inside. Twilight sucked in a whinnying breath, and then let it out with a soft moan. Her hand went swiftly to her belly and pressed down; Trixie could make out the gentle bulge of her copious endowment straining against her marefriend's middle. "So full," Twilight whispered. Twilight's own cock, fully engorged and swaying with faint arousal, drooled a steady stream of precum between Twilight's cleavage, even as each faint thrust of Twilight's hips forced her hefty flare to bob up between her generous tits.
Trixie smirked. Twilight smiled back. They didn't need to talk to know where to go from here.
Grunting, Trixie lowered herself until she was all but hugging Twilight's prodigious chest. Their plush breasts smooshed together, sandwiching Twilight's own great cock between them. Then, holding her marefriend close, and letting their legs twist together, Trixie smiled and began to thrust.
Soft paps and slaps of flesh filled the air alongside the quiet crackles and pops of the fireplace. Trixie's grunts and Twilight's soft moans joined them soon enough, with each of Trixie's firm thrusts making her marefriend squeak a little louder, every pump of her strong hips letting their cum-filled nuts slap gently together.
The pre streaming from Twilight's slit redoubled in volume. Trixie groaned hungrily as Twilight moved her hands up Trixie's teardrop ass, fondling both generous cheeks before moving up to her chest. Trixie's grunts came faster, harder, each thrust bending Twilight's well-filled belly out a little more with her length as Twilight smooshed their tits together between her hands. Their lips touched, warmth and lust and love steaming as they kissed—before Trixie pulled her muzzle away. Beneath her, Twilight began to pant with lust and pressure, her fat cock thrusting between their pre-slick breasts with every thrust either of them made.
With a final whinny of pleasure, Trixie threw her hips forward, and bottomed out inside of Twilight. Twilight's greedy cunt clenched, then clamped around her hilting cock—and then, spasming in climax, the two mares came together. Trixie grunted and groaned, her thrusts going wild as rope after rope of thick cum spewed out in geysers to fill her marefriend's womb. Twilight moaned, her weight squished beneath Trixie's as both orgasms took her at once. Her velvety inner walls spasmed around Trixie's lurching shaft, even as her own member bucked and contracted between its weighty bust sandwich. Each lurch of Twilight’s weighty shaft sent huge volleys of gooey, creamy cum splattering against her own cleavage and cheeks, painting her in thick, dripping white as the adoring cockslut that Trixie had grown to love.
Groaning, the two mares relaxed their grips, and slumped together. Trixie felt Twilight's belly squish beneath her weight; as Trixie's spent erection softened inside Twilight's pussy, the quarts of hot, steamy cum she'd pumped inside her no longer shivering marefriend sloshed and burbled within Twilight's big, bloated cum-gut. Meanwhile, Twilight moaned softly, and licked absentmindedly at a fat glob of cum that had stained her cheek.
Trixie got their first. Lapping it up with a flick of her tongue, she tasted Twilight's seed and grinned down at her playfully. Twilight grinned back, blushing as her hands moved down to her big, cum-filled belly. Trixie gave her hips a gentle rock and savored the sensation of her load sloshing around in the well-stuffed womb beneath her.
"Nice and warm?" Trixie asked, swallowing the glob of Twilight's cum.
Twilight giggled. "Yes," she said. She gave her belly a squeeze, and smiled when her cum-gut wobbled and smooshed in her grip. "Very much so."
