2.5 // Scouting New Territory

Author's Note

Already getting into clop after chapter 2? You bet your ass I am. These two really can't keep their hooves off each other~ :rainbowwild:

Hope y'all enjoy this romp! Going to be taking a bit of a break from clopwriting for the month of November thanks to a "no lewds" challenge imposed upon me by some writing pals, so I wanted to get this out before then. It'll give me plenty of time to work on Starting Your Quest and some other SFW stories, at least.

Happy Hallow's Eve! Swim fast, eat ass!

2.5 // Scouting New Territory

Lavender. Candyfloss. Blue. Warmth.

Sunny's hazy mind is nearly overwhelmed with stimuli as she awakened to the shine of the sun in her eyes -- all she could smell was the sweet, intoxicating aroma of her marefriend's natural scent, cocooning her in its comforting familiarity, and all she can see as her vision focuses is blue, like that of her sapphire mane...

It brought out a contented sigh from her, though her reverie was broken as she reached out to curl her hoof around the mare next to her, and found empty air.

"Izz...?" Sunny groaned blearily, squinting in the light of the sun as she sat upright, glancing around Izzy's eccentrically-decorated bedroom (much like the rest of her home, it was resplendent in "unicycled" decorations of her own creation) as her brow knit in confusion. "Izzy?!" she called out, louder that time.

From downstairs through the open doorway, that familiar, peppy voice answered her, "Down here, Sunny-bun~!" she said cheerily, the whistle of a teakettle punctuating the end of her sentence. "Just wait a bit, I'll be right up!" she added.

Izzy giggled mischievously as she rummaged through her tea cupboard for ingredients, periodically pulling her head out of the storage compartment to spare a confirming glance at the pages of 101 Ways to Please Your Lover.

She'd woken up a bit before Sunny to allow herself to rustle through the pages of the hedonistic tome, and what she'd read so far had been a goldmine. With so much time for the mages, apothecaries, and scholars of the former empire to perfect various magics before its dissolution, she never would have guessed that sex magic would've been among the most studied fields!

...Though, given how important sex was for the continuation of any species's existence, she supposed it made sense. Helpfully, there also seemed to be a disproportionate number of spells geared towards relationships between two mares, which definitely suited her just fine -- though it did have her wondering, were the stallions of ancient Equestria uncommon or impotent in some way? From what she could tell, there was a paltry amount of advice in here for stallions...

Questions like that could wait for later, she supposed. What mattered now was brewing up these special teas before Sunny grew suspicious and came down to investigate...the two blends she was crafting, in particular, had some rare ingredients she'd rather not waste if she could help it. Each of them had a spell component along with them, too; although helpfully the instructions for these incantations were laid out very simply. The plainly-worded explanations were simple enough for even the less experienced (or non-experienced, in her case) to understand, which she certainly appreciated the long-dead authors of this book for.

She carefully portioned out the listed ingredients into each teacup; her own in the left one, and Sunny's in the right one. A moment of discomfort left her as quickly as it appeared; though the mare probably wouldn't appreciate the surprise at first, she was sure she'd grow to love it quickly enough~

Their teas took on a similar deep-purple hue as Izzy poured the steaming-hot water over the differing blends; the aphrodisiac-laced floral scent already had her nethers twitching and she hadn't even cast the spells on the teas yet! Pushing the two cups apart so that one spell didn't accidentally hit both of them, her eyes pored over the pages one last time as her horn alit with sorcerous might.

Her eyes slid closed in concentration as she did as instructed, envisioning her desired outcome as she felt power flowing out of her horn and into the tea in front of her.

She let out a breath she wasn't aware she'd been holding as the casting of her very first complex spell completed, the depths of her teacup shimmering with magic sparkles that didn't quite show up unless you looked for them...

Izzy hesitated briefly as she thought back to some advice Alpha had given her about never accepting a drink from a stranger, but steeled her resolve. She had no intention of forcing Sunny to do anything she didn't want to, and besides, the spell had been cast now -- there was no taking it back without also throwing out those rare ingredients she'd just used.

With thoughts of Sunny filling her head, she poured all of her focus and resolve into her second spell of the day.

"Just wait a bit, I'll be right up!", came her marefriend's reply from downstairs.

Sunny hummed in interest as she crawled out of bed, trotting up to Izzy's mirror and grabbing a hairbrush off of the dresser. Izzy's shimmering blue hairs were numerous within the bristles, but she shrugged uncaringly. She'd already been a lot more intimate with Izzy than sharing a hairbrush, so what was the harm? Besides, it was only for one morning.

As she ran the brush through her frazzled mane to attempt to wrestle it into submission, the subtle shuffling sounds downstairs and the rattle of cupboard doors made her ears perk in curiosity. She could peek on what her mare was doing down there...but, if she wanted to keep whatever-it-was a surprise, she supposed she'd at least humor her.

Smiling and nodding to herself as her unrestrained, frizzy 'do achieved some semblance of normalcy through her efforts, she set the brush down back where she'd found it -- now with one or two strands of her purple mane caught in the brush next to Izzy's long, wavy blues. She glanced at her pair of hairbands sitting on the dresser, and promptly 'tsk'ed as she batted her hoof at them. Tying up her mane could wait until they were ready to head back to Maretime Bay, and besides...it took forever to do that with her bare hooves! Maybe she could get Izzy to help her with her mane...the thought sent a brief storm of butterflies through her stomach as a dreamy smile spread across her face.

As if the mare knew she was thinking about her, the telltale clop of hooves up the stairs, accompanied by the twinkly sound of magic, heralded Izzy's ascent towards the bedroom. As she crossed the threshold, she cheerfully announced her presence, "Gooood morning, Sunny! Hope ya slept well!" She exclaimed, her voice a living embodiment of carefree energy despite the early hour.

A pair of teacups was offered to Sunny on a levitated wooden tray, and she gratefully took the cup on her right with a smile. "Thanks for making tea, Izz. Mmh, this smells great..." She muttered, a slight flush coming to her cheeks as the scent's notes made her feel fluttery for reasons she couldn't quite explain. She shrugged it off as butterflies from what she'd been thinking about moments prior, and took her first sip of the tea.

Its strong, earthy bitterness was unexpected, but not unwelcome -- it tingled hotly in her throat as it went down, a dense warmth settling in her belly as the tea's magical effects began to take root. "W-wow, this is, umm, strong! But really good! It tastes a little...root-ish, at first, I guess? But I can't stop myself from wanting more..." Before Sunny knew it, she'd downed the whole rest of the cup in one swig.

As Izzy drank her own brew, she appeared to slurp at it more and more aggressively at first, until she looked down and realized it was empty with a frustrated groan. With her attention taken off of tea-drinking for now, what her marefriend said finally had a chance to register in her brain... "Your tea had the earthy taste? B-but...that was...supposed to be mine...mmmh..." The unicorn trailed off with a shuddering sigh as she felt herself wink against the cushion she was sitting on, a splatter of her juices quickly staining the seat beneath her as a full-body, pins-and-needles feeling of warmth overtook her, as potent as the heat of a summer's day. A feeling of need, of emptiness. Of roaring, demanding lust. The earth pony beside her was starting to look more and more jumpable with each passing moment...

The dense warmth in Sunny's belly began to travel further south, in a way that made her shudder with an unfamiliar, building feeling as her heartbeat thrummed in her ears. A pinching, swelling sensation began in the space between the bottom of her labia and her teats, and she shuffled uncomfortably in her seat as that sensation grew, and grew, and grew...until she could feel a distinct weight on her underbelly, twitching and throbbing in time with her heartbeat as unfamiliar muscles flexed and a long, heavy something thumped up into her underside.

"W-what's...what is happening?" Sunny panted out between labored breaths, her eyes screwed tightly shut as full-body shudders rolled through her.

Izzy's eyes boggled out of their sockets as a thick, throbbing, dark-orange length grew right before her eyes on her lover's undercarriage, the size thoroughly exceeding her expectations as that flared pillar of flesh reached halfway up her barrel, with nearly a hoof's width of diameter. "Woooah..." Izzy said breathlessly, eyes sparkling as she stared wide-eyed at her marefriend's exhilaratingly well-endowed new appendage. She licked her lips as her marehood clenched hungrily from the sight; she'd never been attracted to stallions before, but the flash-flood of hormones overwhelming her brain, combined with the fact it was Sunny's dick she was looking at and not a stallion's, were combining to make a strong case!

Sunny's eyes opened as the strange feelings abated, though she still felt an odd, stiff weight pulling against her nethers. Glancing down between her legs, she did a double-take as she saw the dark orange pillar of flesh jutting out between her hindlegs, pulsing angrily with her heartbeat. "I-Izz...what the buck did you put in that tea?!" Sunny asked incredulously, eyes narrowing at the unicorn...who wasn't paying much attention to her face in return.

"Ohh, nothing~! Just some stuff I read about one time..." She replied airily, pointedly avoiding eye contact with the other mare -- her every thought irrevocably focused on the tantalizing pillar of flesh that practically demanded her attention, as well as the heavy pair of hoof's-width nuts that indented the cushions beneath it. 'By the stars, earth ponies sure are well-endowed!'

"And you didn't even tell me before giving it to me?" Anger filled her tone as a fresh bout of unfamiliar, stallionly hormones overtook her mind, giving her all sorts of ideas of how to punish the mare for her deception... "I think you need to be taught a lesson in manners, filly."

A shudder rolled through Izzy as her incensed partner's phrasing tickled the imagination of her lust-addled mind, conjuring images of what those lessons might entail. "Umm...s-sorry for giving you a-mmf!" Izzy's stuttered, wide-eyed apology was cut off by Sunny's hoof firmly gripping the back of her head with unyielding earth-pony strength, putting her muzzle-to-flare in a lewd staredown with the mare's fat, flexing crown. Her eyes crossed as she attempted to look at it, face flushing heavily with arousal as her rebellious loins demanded her to do something -- anything -- to appease the pillar of virility before her. Her jaw slackened as her thoughts began to cloud over completely, her aroused, heaving breaths exhaling as clouds of steam onto that dominant, intimidating breeding rod. Suddenly, the more experienced of the two mares found herself to be the one scouting new territory, and the thought was both rousingly terrifying -- and terrifyingly arousing.

"If you really want to apologize, you can start by getting rid of this star-scorned thing..." Sunny groaned, her hips giving restrained little twitches and bucks as she grit her teeth and bit her bottom lip, her flare twitching angrily at the teasing wet heat of Izzy's breaths.

"B-but I don't have a counterspell for it-" Izzy rebutted halfheartedly, though an impatient whinny of frustration left Sunny's nostrils from the unsatisfactory response.

"You're a smart mare, figure something out, Izz! You've probably done something like this before anyway, right?" Sunny nearly whimpered. The needy, insistent fire in her loins that had built up from taking in lungfuls of Izzy's lurid, aroused scent was no longer insisting to be released -- it was demanding.

While it was true that Izzy was more experienced than Sunny, it wasn't saying much considering Sunny's recently-virginal state...she'd had a few meaningless flings of mutual relief with other unicorn mares during the season, but never with a stallion -- which was partly Alphabittle's protectiveness and partly her own preference for other mares. 'Okay, c'mon, Izzy Moonbow! Your marefriend needs you! It can't be too different than polishing a horn...a really thick, throbbing horn that's *gulp* long and flexible enough to stretch out your throat...' Again, Izzy's higher thoughts screamed the terrifying danger of such a prospect -- and again, those thoughts lost out to heat-addled assurances that feeling her beloved's rotund nuts clenching against her chin as they blasted her belly full of heavy earth-pony seed would be more than worth any conceivable level of discomfort it took to earn such a reward.

Izzy bit her lip as she crept her face down to those weighty orbs, that heavy scent lulling her into obedience as she buried her face in that potent, steamy space between Sunny’s sheath and scrotum. Those familiar notes of earth and tangerine mixed with the spicy musk of stallion in a way that had Izzy flooding the cushion beneath her as her nostrils flexed, greedily inhaling lungfuls of that addicting scent as her eyelids fluttered erratically.

Her tongue slid out of her mouth after a few moments of indulgence, that broad muscle pressing into Sunny’s plump orbs with firm reverence; the sensitive flesh indented beneath her touch from each lick she gave, making the dickmare’s forehooves twitch and shudder in Izzy’s mane as her hindhooves locked behind the other mare’s back.

“Oh b-buck!” Sunny swore, gritting her teeth as Izzy’s erotic worship toyed with her hair-trigger of inexperience, steadily eroding her vast earth-pony stamina with each greedy slurp of that wide tongue across her impossibly sensitive pair of nuts. New and unfamiliar feels assaulted her relentlessly with each lick, an insistent pressure and burning surge of arousal that made her eyes roll back as her head flopped back bonelessly against the wall behind her.

Each deep moan that slipped past Izzy’s lips vibrated through Sunny’s oversensitive flesh like an earthquake of ecstasy, building higher and higher in intensity as the unicorn’s tongue swirled a trail past every needy inch of her cock, leaving her spit-slickened balls to clench and tingle in the chill morning air as Izzy turned her lustful attention to the rest of Sunny’s member.

That curious, talented tongue made its warm, slick voyage up her length, mapping out every bump, ridge, and vein from her sheath to her medial ring. Hot globs of preseed oozed from her twitching tip and stained Izzy’s mane with stark white drops, making her shudder as she felt it dampen her scalp. It drew her attentions higher, leading her to give Sunny’s medial ring a little farewell peck as she giggled coyly, “Mmh, this thing’s bucking huge, Sunny-bun…you’re such a generous marefriend, leaving this all for me. Whoever says sisters have trouble sharing has never met us~”

The feeling of hot, panting breaths against Sunny’s tip caused her to creak her eyes open, needy whimpers escaping her throat as the unicorn’s exhalations steamed against her desperate flesh. Izzy gave her that familiar half-lidded, come-hither stare from the night they’d first kissed, and Sunny felt her eyes screw shut once again as that glorious tongue swirled slowly on her pulsing cockhead.

The older unicorn didn’t waste any time from there, planting her lips squarely on the bulbous crown of Sunny’s flare as her tongue darted out to lap directly at the meatus of the earth pony's tip. After a few hoof-curling, spine-tingling moments of bliss, Izzy’s mouth opened wider as she attempted to fit the fat, flared head past her lips, motivated by the initial difficulty of wedging that glorious thickness through her jaw.

“Izz…y-you don’t have t-to fit it in if you—hnnguuuh…” Sunny’s jaw slackened mid-sentence as her cockhead was surrounded by panting, damp, rippling, inescapable heat, like nothing else she’d ever felt before…the delirious, overwhelmingly intense pleasure of a stallion’s first blowjob. Her hips trembled with barely-restrained desire, fighting the coltish urge to just drive herself hilt-deep in Izzy’s hot, eager throat with the first thrust and unleash the pent-up payload that her instincts were all-too-eager for her to release.

Izzy giggled mischievously around the cockhead filling her mouth, delighting in the way that Sunny’s adorably arousing attempts at dominance melted into passivity as her needy new instincts were appeased. Testing her own limits, Izzy’s lips caressed every millimeter of Sunny’s flesh as it slid deeper inside her eager oral cavity, driving further adorable moans and whimpers from the once-dominant mare as Izzy showed her exactly how a unicorn sucks.

Lewd slurps and muffled moans filled the room as trails of saliva and pre drooled down Izzy’s chin and neck. As her lips reached the medial ring, the fat flare in her mouth butted up against the entrance to her throat; as Izzy had feared, there was no way she’d be able to fit the whole thing inside of her greedy gullet unless she throated half of that bucking monster.

…Which was surely impossible, right? Why was the very thought of attempting such a depraved act, feeling those heavy marenuts churn as they filled her thirsty throat, turning her on so much? It must’ve been that addicting musk clouding her thoughts, but she couldn’t bring herself to be mad at something that smelled so good…

She braced herself as she felt Sunny begin to pull away from her, but is still caught off guard as those powerful earth-pony hips buck upward into her throat, slipping that fat flare into her esophagus with an erotic, choked *glrk!*

Sunny’s hooves twitched involuntarily as her grip on Izzy’s mane tightened, insistently guiding her further onto her throbbing tumescence with each passing moment. The unicorn’s throat bulged obscenely as Sunny’s marecock slid deeper into her, her eyelids fluttering as that throbbing intrusion started to make it harder to breathe. She can already feel herself exceeding her limits, but she’s determined to push past them even further for the first mare she's ever loved so wholly and completely -- and who has loved her the same way in return.

Involuntary tears streamed down Izzy’s face as her cheeks flushed heavily with arousal, the hot blood pulsing through Sunny’s length amplifying the heat in her face even further. The warmth of Sunny’s cock, the growing lack of oxygen in her lungs, and the sheer nirvana she felt from devoting herself to the other mare’s pleasure had all combined to bring her to a delirious high.

Sunny, meanwhile, was realizing why young stallions seemed so obsessed with finding the first warm hole that would take them at every opportunity. Izzy's mouth and throat were positively exultant; damp, hot, and ceaselessly undulating around every sensitive inch of her throat-straining thickness as its broad flare ground against Izzy's eagerly swallowing depths. "Holybuckingnnnfff~! Izz, I take back everything I said before, save that bucking tea recipe. You're the best marefriend ever." Sunny growled, hips flicking forward to accentuate her praise as her newfound stallion instincts took over.

Mercifully for Izzy’s lungs, she finally reached Sunny’s sheath with one of those fitful thrusts, swallowing eagerly around Sunny's cockhead as her head twisted to the side to prevent her horn from poking a hole in Sunny's barrel.

Sunny’s eyes rolled back as her hooves curled, shoving Izzy down hard enough to make her muzzle scrunch into her underbelly as the unicorn’s vision began to darken from lack of oxygen. As an inexperienced "stallion," Sunny was way too eager and wasn't letting her mare breathe -- not that Izzy had a problem with it, necessarily! Feeling those heavy nuts slap against her chin as she took her marefriend all the way to the base, her lungs burning with need, was a glorious experience.

She did, however, want to finish Sunny off without passing out in the process. It was with this in mind that her shimmering aura coalesced around the immense twin weights resting against her chin, entrapping them in a warm, spine-tingling massage that drove Sunny careening over the edge in an instant.

Her every thought and focus narrowed to the hot, damp, massaging tightness that surrounded her length, a full-body shudder quaking through her as she held Izzy firm, despite the other mare’s struggle for oxygen around the horsecock flooding her throat. She’d utterly devolved into single-minded studding, claiming her marefriend’s throat for her own pleasure as she reveled in the intensity of a stallion’s orgasm.

Every thick pulse of seed that splattered into Izzy’s stomach made Sunny’s forehooves clench at the unicorn’s mane, a hot wave of fire washing over her with each gooey throb of her release as her tongue dangled out of her mouth, vision going white from the overstimulation of having her heavy orbs eagerly milked by Izzy’s massaging magic.

The unicorn’s muffled groans of discomfort and hungry swallowing ripples of her throat added even more to Sunny’s pleasure, utterly draining her dry as her eyes crossed deliriously. Izzy’s flared nostrils shuddered as she appeared to sneeze, eyebrows furrowing in discomfort as Sunny’s seed splattered out of her nose in twin trails that only added to the utter mess that was being made of her slurping maw.

Being used so carelessly drove Izzy wild. Any inkling of dominance she’d had over Sunny due to her prior experience had been well-and-truly facefucked out of her by now, leaving behind nothing but eager submissiveness. It was starkly unfamiliar territory, considering she’d always been in charge of their lovemaking before…but she was clearly loving the loss of control.

Her utterly soaked, frenetically fluttering marehood erupted against the cushions beneath her as she came hard from being used, abused, and asphyxiated by Sunny’s relentlessly driving hips and thick earth-pony marecock. Her vision went white despite the blackness creeping into its edge; the lack of oxygen combined with the brain-blast of endorphins nearly made her feel like her soul was leaving her body.

Hurriedly, as if realizing Izzy’s increasingly weak movements beneath her, Sunny began to pull herself free of the addictively gripping throat massaging her length, no matter how much her instincts (or her flare) resisted the notion.

As Sunny’s still-firm flare slid past Izzy’s lips with a sucking pop and a shuddering, frenetic breath, it left behind a mess of seed and saliva as she took in greedy gulps of air, flopping back onto the cushions as she stares dazedly at the ceiling of her bay window, thick earth-pony seed bubbling out of her nostrils as she attempted to breathe through them. The blackness at the edges of her vision steadily retreated, her full faculties slowly returning to her as the two of them recuperated from their intense orgasmic peaks.

“Buck…yeah…” Sunny panted, gazing with wonder (and a bit of pride) at Izzy’s utterly wrecked countenance. Once her eyes locked on her cum-glazed length, though, her expression shifted to a mischievous smirk. “Oh, Izzy~” She beckoned in a devious, singsong tone.

“Y-yea…(hic) yeah…?” Izzy hiccuped blithely, rubbing her tummy with a hoof as she basked in the sloshing warmth of a job well done. Stereotypes about earth-pony virility were well-founded, judging by how bloated she felt…

“You made a mess, Izz…I’m gonna need you to clean it up~” Sunny taunted, waggling her length imploringly at the other mare as she gripped herself near the base of her length.

Izzy moaned tiredly as she shifted closer to the other mare’s loins despite the numb, tingling feeling in her limbs, obediently applying her lips and tongue to Sunny’s pulsing, eager marecock as she swirled every inch of that glorious pillar clean of spunk.

As her deft muscle swiped up the last bit of Sunny’s residual essence, she gave it a firm smooch on the crown as her tongue flicked at the meatus, getting a surprised groan from Sunny as her tip flexed and a fresh glob of preseed erupted from it. A stunned realization struck Izzy: the pillar of spit-shined flesh continued to tremble and pulse with arousal, despite having just released a massive payload into her throat. Those heavy balls, too, looked as full as ever… “B-but I thought, stallions couldn’t…”

“Not sure if you noticed, Izz, but I’m no stallion.” Sunny said hungrily, flicking her hips to boop Izzy’s muzzle with her drooling cocktip.

“Coulda fooled me, with this massive buckin’ thing between your legs…” Izzy teased back, tongue darting forward to flick up another glob of pre. On shaky hooves, she clambered off of the bay window bench and stood upright next to the still-seated Sunny.

Taking a moment to stretch and shake out the kinks in her muscles from how her marefriend had roughly handled her, she rested her front half on the cushioned bench with crossed forehooves, and waggled her rear enticingly behind her, "I think you know what to do, babe~" She purred coquettishly, batting her eyelashes at the wide-eyed she-stud as her restless dock swished her flowing blue tail around. As Sunny hurriedly left the bench and approached Izzy from the rear, the unicorn’s intoxicating, sweet-smelling scent spread through the room like a haze, potent enough to make Sunny sway on her hooves as her length clenched, slapping loudly up against her belly and between her teats.

Truthfully, being a mare of her inexperience, Sunny didn't know the first thing about how a stallion mounted a mare -- but luckily for her, she wasn't the one in control at the moment. The dominant, lustful persona that had come as a package deal with her new equipment, however, was.

The wordless, primal nicker she uttered as she stalked up to her presenting marefriend's winking, utterly soaked snatch caused a thrill of submissive arousal to rattle its way down Izzy's spine, a needy moan flowing out of her panting mouth like hot lava as her entire body buzzed on the high of anticipation.

"Mmh, please don't keep me waiting, Sunny...I need you~" She whined, the wanton arousal in her tone pleasantly stroking the fires of the she-stud’s ego. Her teeth nipped teasingly at Izzy’s cutie mark before she mounted the taller mare, having to go up on her tippy-hooves in order to get enough traction to fully clamber onto the eager unicorn’s back.

Sunny’s muzzle sank into Izzy’s mane as she greedily inhaled the other mare’s scent, the warmth of contented dominance settling in her chest as that pale, fluted horn filled her vision, flickering erratically with magic.

Her plump teats mashed against Izzy’s trembling dock as her length throbbed between the unicorn’s firm nubs, allowing herself a moment to inhale another intoxicating lungful of Izzy’s vapors as she pulled her rear back and lined up her flared tip against that sodden, winking marehood. Those trim purple flanks trembled in anticipatory delight as the weight on her back triggered a deep-seated response inside of her, her hindlegs widening in stance as her rear dipped down to give her “stallion” better purchase to rut her with.

Sunny snorted in recognition of her mare’s acceptance, shuffling back a bit to allow her cockhead to press more insistently into those beckoning dark-purple lips and the tantalizing, healthy pink just beyond them. Finally, with a shared, trembling moan from both of them, Sunny felt her head wedge itself into Izzy’s cunny for the first time.

The warmth! The tightness! Not even Izzy’s throat could compare to how firmly and insistently her tunnel seemed to beckon her to thrust deeper, eagerly accommodating despite how snugly the unicorn fit around her thick earth-pony marecock.

Every inch deeper brought with it a dizzying cornucopia of emotion; love, gratitude, eagerness, desire… Sunny found herself eagerly anticipating each little squeal and shudder that a firm ridge or squiggly vein on her length would force out of Izzy’s mouth. Their breaths devolved into a duet of panting, huffed breaths, each of them indulging in the ecstasy of the moment as their eyes closed.

“Buck!” Sunny swore as her medial ring popped itself inside Izzy with a squelch, her forehooves tightening their grip around Izzy’s barrel as her nuts shuddered and trembled from the sudden jolt of stimulation. She could already feel her second peak approaching, but resolved herself to hold out until Izzy reached it first…it was what a good lover would do for their mare, and she wanted to be the best she possibly could be for Izzy. “I love you so much, Izz…” She panted into the other mare’s ear, grunting and huffing with exertion from each ball-slapping thrust. Each surge forward was making it harder and harder for her to hold back, her inexperienced body nearing the point of overstimulation as her flare squished against the barrier to Izzy’s womb.

“S-sunngh-sunnahhh-” Izzy squeaked out between each body-quaking thrust against her once-untouched deepest barrier, her attempts at communication thwarted by her mate’s pace as she was driven towards her edge with relentless vigor.

Her eyes crossed as her horn started to fizzle with undirected energy, Sunny eying the sparkling protuberance hungrily as she began to lick her way up the length; lovingly fellating its tip as tingly sparks of magic bounced around within her mouth. The added stimulation drove Izzy over the edge instantly, that familiar magical residue filling Sunny’s mouth with tingles as she greedily swallowed her marefriend’s concentrated energy.

With a deep, shuddering groan, Sunny released Izzy’s horn from her ministrations as it continued to spark and crackle, flickering like a failing lightbulb as Izzy used what little remained of her concentration to return her magical attentions to Sunny’s swinging nuts.

“Mmh, Izz, I’m g-g-gonna-ngaaah~” Sunny cried out as she took a half-step forward, eagerly sinking herself deeper as she was thrown over the cliff of pleasure all at once. The way Izzy’s depths tried to resist the growing size of her flare with their iron-hard squeeze, the positively incredible winking and rippling she could feel all the way to the base, and the brain-blanking pleasure that that massaging magical aura provided…she had no hope of resisting all three forces combined. “Izzy!” She screamed out, giving herself to the rapture of climax after resisting for as long as she could.

Sunny’s heavy nuts jumped and clenched against Izzy’s winking clit as her magic milked and massaged those glorious weights for every last drop they contained. That once-flickering fire of passion in Izzy’s belly blazed like a bonfire now, hormone-driven thoughts taking the reins as she imagined how many foals such a virile dickmare might be capable of putting in her. As the least-related couple in Equestria, it was practically their duty to help repopulate the country as much as physically possible…

“That’s it, fill me, Sunny! Bucking breed your marefriend!” Izzy blurted out, her face reddening the moment that the impulsive request left her lips. She couldn’t deny its effectiveness as Sunny jerked back mid-orgasm and slammed herself deeper, making the unicorn’s flanks ripple from the impact. The dickmare’s broad corona wedged its way into the opening of Izzy’s cervix as Sunny reached the apex of her plunge and held herself there, depositing the rest of her copious load directly into Izzy’s womb, as instructed.

“St-stars above…” Sunny groaned deeply, nibbling one of Izzy’s ears between her teeth as all the stress and tension within her melted away into a white-hot, massaged ecstasy. The shimmering purple aura around her heavy seed-stores was ceaseless and insistent in its milking motions, making her eyes cross as she focused completely on that nagging, single-minded instinct to breed.

“Yesss~” Izzy hissed through clenched teeth, feeling her depths beginning to swell from the other mare’s seemingly endless tide of earth-pony virility as a bloated feeling of heat built in her belly. Both hers and Sunny’s hindlegs trembled in tandem from the strain but held firm as a thin stream of Sunny’s seed oozed out of her overfilled cunny to pool on the floor beneath them, overflowing past the tightened intimacy of their union from sheer pressure. “Mmh, you came so much, Sunny-bun…gonna be feeling that for a while…” She said breathlessly, her flanks trembling and jiggling against Sunny’s underside with each panting, labored inhale she made.

“I hope you’ve got more of that tea, because we are definitely doing that again…” Sunny panted, a shudder rolling through her as the weight between her hindlegs began to fade away in a shimmer of purple sparks, the magic behind it utterly spent after such vigorous, energy-draining rutting.
