Chpt 1 - The Problem

Rays of sunlight seeped through the blinds, tickling the sleeping mare’s yellow fur. The mare smiled subconsciously, as she rolled onto her back. She was laying in a traditional wooden bed, hoof carved by one of the best woodworkers Ponyville had ever seen. The female pony was snuggled beneath a burgundy blanket, checkered by golden silk lines that glowed under the sunlight. Kissing the air with overly dramatic smacking noises, the mare brought her soft hooves to her eyes as she awoke from her slumber. Her mane was a cool bluish hue that complimented her cute coat.

Sonja rubbed the sleeping dust from her eyes, trying to pull away the hazy curtain that accompanied her sleep. Partially dazed, the mare tried to sit up. The metaphorical gears in her back creaked and lurched as she tried to move herself into an upright position. The blanket crawled slowly to her hindlegs. A sweet scent wafted up to Sonja’s nose, as she inhaled lightly. Sonja panted as the smell penetrated her snout, delivering a scent that befitted a goddess.

Having finally made it to a sitting up position, Sonja lurched backward so that she would parallel to the headboard, when she felt a passion that she simply adored. “Urnnnggg,” the earth pony moaned as she felt the soft tinkling of the bed cover slide in-between her nethers, the polyester caressing her marehood.

Looking down, Sonja noticed the trail of marecum that she had left just by repositioning herself. The liquid glimmered in the sunlight as it was absorbed by the fabric of the bed. A blistering heat burned up inside of her, the mere sight of her wetness sent her libido skyrocketing. She gently moved one of her front hooves and began to circulate her clit, carefully massaging the fleshy bulb. Sonja let out an “Aaaah!” as she felt the sensations spiral upward to her brain, feeding her lust for more.

As she took her other hoof to simulate her moist pussy, a jolt blazed through the mare as her coat caressed her hardened nipples. Sonja bit down on her lip as she came to the realization of how protuberant her teats were. Bringing both hooves to her breasts, she rubbed her breasts eagerly, wanting to make up for the years of ignorance she had cast down on them. Sonja was amazed by every pull she made upon the mounds, admiring the give of her skin. Pushing downward, she could feel her teats swell, as strands of her fur teased and tickled her nips. Sonja moaned as she moved her hoof around the uncharted erogenous region. Lips quivering, the mare slowly encapsulated her perky right nipple, circling slowly around. In a swift motion, Sonja pinched the inflamed teat, bracing her underlip like a pincer as the compression elicited a muffled groan of pleasure.

The yellow mare’s jaw clamped hard onto her skin, digging its way deeper into her lip. Sonja winced as she worked her way around her nipple, gripping and stretching it. She could picture a young foal gripping on her teats, heavily suckling away. Sonja pictured the newborn lapping up her milk, tongue lashing against her leaking nipples. Oh how the thought sent waves of undiluted passion to her nethers, as liquids flooded down onto the bed. Her neck craned backward as she brutally accelerated her movements, trying ever so hard to push herself to orgasmic bliss. Pulling, stretching, biting, Sonja’s face flourished from the pent up frictional heat. But all that awaited her was an even more intense fire in her loins. Unleashing her grasp on her lip, she let out a soft cry, feeling herself melt into the drenched sheets.

“No, this isn’t enough! uggha~” Sonja cried as she threw away her formalities and shoved her hoof in as deep into her cunt as possible, practically fitting half of it inside of her. Granted, her hooves weren’t the biggest, certainly smaller than an adult mare, but larger than a filly’s.

Sonja twisted and turned her hoof, trying to squeeze in even more inside of her. Her hoof was doused in thick nectar, lubricating her front leg with copious amounts of cum. Moaning, she squirmed and twisted, trying to put her entire hoof inside of her dripping slit, but it was just too big for her. Nevertheless, she continued rotating and pushing, desperately in need of penetration.

Her hoof brushed against her soft inner walls, clawing desperately on muscle, trying to climb deeper. Clenching as hard as she could, she begged, pleaded and moaned. She needed to just...get....a little....more....inside. Pushing as hard as she could, she felt her hoof slip and lost the majority of the depth she had. Her cunt grasped eagerly at the lost space in a horribly delayed reaction.

Exasperated, Sonja pulled her hoof out of her moist cunt. She just wanted to feel relief, but her pussy denied the attempt. Her mind flustered, tongue lolled out; she felt like a needy slut. The sheer thought of being penetrated by a nice long object sent rabid heat pulsing through her cheeks. Eyes drooping, she laid back onto the headboard, panting heavily.

“Oh, please~” she moaned as her body clenched at the emptiness inside her. Her marehood was acting on overload, pulsing and quivering, wanting desperately to be filled. But Sonja’s attempts were foiled, she was nothing but a teapot, wanting to be taken off the kettle, to be relieved of such burning desire.

To her dismay, lubricant blitzed out of her cunt, in an attempt to hit something...anything, that would sedate her loins. Sweat dripped from her mane, trickling down her adorable snout, pooling, in an attempt to relieve her fever pitched skin. Sighing, Sonja tilted her head onto her shoulder when she noticed the most inviting object just a few feet away from her.

Shuffling herself together, she made an attempt to make it to the foot of the bed, a trail of marejuices laid a visible line in her path. Sonja stood up, letting torrents of girl-lube leak out from the desperate fucking she tried earlier. She eyed the widest, most insertable object she had ever seen before.

“Why didn’t I think of this before?” groaning softly to herself.

Sonja eyed the inviting bedknob, marveling at its smooth curves, the thick shape and the slickest object she had ever seen (though that might have been because she did just let loose a flurry of nectar on it). Hovering herself over the object, Sonja lined herself up before slowly lowering and rubbing her nethers over the knob.

“Ohhhhhhh~” she cried, as she felt the material grind back against her ministrations, rubbing and spreading her lower lips.

“Celestia, this is the most amazing feeling! It’s soooo rounnd~”

In a daze, she continued to work her way around the top of the spherical knob, but it wasn’t enough for her. She wanted to be penetrated, and she could not wait for such pandering. Sonja needed the bedknob to be in her loins, rubbing her inner walls and travelling deeper and deeper. These actions were just not cutting it.

Taking a deep breath, she let her muscles give way, letting gravity handle the insertion. And that it did. Sonja moaned as she felt the spherical object spread her nethers wide, pushing her moist cunny open for the massive wooden head.

“Ahhhhhhhh~,” Sonja moaned as she felt the wooden stopper push up into her. Her face burned with arousal, causing the mare to sweat profusely. The yellow pony shifted her hips slightly, letting a few centimeters more inside, stimulating her vagina immensely. Scrunching her snout tightly, she fought back a taxing battle with her flesh. Sonja could not let the pleasure escape her, it was too immense to let go unfettered. The pure pleasure of being brushed by the expertly carved ornament, was too much to hold in. Sonja felt like she was being held in a sauna, the heat just pulsating, cycling through her limbs like it was an enraged animal pent up in a cage.

Her mouth gaped open, strands of saliva bridging between the roof of her mouth and her jaw. The strands waggled from the mare’s heavy breathing, trying ever so hard to keep her mouth shut, to let the pleasure swirl within her for just a bit longer. But alas, her body gave away as she unleashing a throaty moan, powerful enough to send even the most elusive, delectable apple on Sweet Apple Acres to come crashing to the ground. Her vocal cords sang the delicate sonnet of a mare in much of a need to feel full, to be penetrated, to be taken and pumped full of hot gooey semen.

But as much as she would like that, she had no way of gaining access to a stallion this early in the morning. Such activities were normally performed under the cloak of the night and the sun was a very declarative foe to a mare who simply needed to be pleased. Still feeling the inferno spiking in her nethers, Sonja attempted to get up off of the makeshift sextoy, only to slip on the heavily lubricated object she had been fucking.

“Whooooooaaaa~!” the mare proclaimed as her eyes bulged from the sudden and somewhat deeper penetration that she felt before. This gave the naughty girl an idea. Putting one leg up on the bed, she began to winch herself up and down ontop of the object. Even though on the change in depth was quite minuscule, from Sonja’s perspective it felt like tens of yards. A massive flare mining through the female’s slick inner flesh.

Sonja’s mind was completely immune to the amount of torque acting on her poor lower leg, the pain was simply obliterated by a torrid flurry of pleasure signals, schlicking their way up her body. She was simply lost, no, she was adrift, floating in the millions of tiny signals flickering, let loose onto her teenage spine. Her hoof was furiously rubbing in the near vicinity of her clit, hell, she didn’t even care. In her mind, her limbs were nonexistent, all that remained was her deep cunny and her makeshift wooden penis.

Bouncing up and down like a hyperactive filly being told they were about to get a chilled ice-cream treat from the local grocer, Sonja kept thrusting. In her mind, she imagined she was being fucked by her colt-friend Rumble, whose name actually fit his cock quite well. She dreamed of being on top of him, riding his massively thick stallionhood, feeling the blood thickened veins graze across her soft walls. She can imagine clenching his penis, holding it within her, tightening. She wanted to milk all the cum he had, to let a violent cum explosion be forced within her. Sonja could feel his bulky chest, lightly fluffed with his smooth fur. She would rub her hoof between the gap caused from her cunt to his neck, stroking his toned muscles. Then he would pull her in close and they would passionately kiss as he climaxed with herrrRRrrrr.

“ooahhhhhhhh~”

Sonja blinked, snapping out the sexualized fantasy to notice that she had completely drenched the entire footboard of her bed in her own juices. The bedknob was totally soaked in marecum, and a pool of the liquid gathered on her sheets like a shimmering oasis. She have given the foot of the bed a fresh darkened coat of sealant, created by her own orgasm.

Pulling herself up from the homemade penetration device, Sonja still felt a slight tingling sensation between her nethers. A wave of pent up relief emancipates itself from her pulsing cunt, splashing on the floor in a large puddle. Panting from such a breathtaking orgasm, Sonja takes in a whiff of her own liquid arousal. A sensual ember rekindles within her chest, taking her breath away in an instant. Bringing her snout up close to the footboard encased in her glimmering mare juices, her brain reroutes to overdrive as she feels her arousal take control.

Flicking her tongue free from her maw, she closes the gap between the still dripping wooden head, slurping up the liberated pleasure. Her tongue quivers in delight, the warm feeling of delicious syrupy nectar beelines over every one of her excited tastebuds, blessing them with her very own delectable juices. Sonja’s mind ignites with desire, tongue lolling out, dripping with a vulgar concoction of her own cum and the drool her eager mouth generates ever so copiously.

“Oh Celestia, this is so yummy~” Sonja mulled as she continued to lap up even more of her juices in a desperate effort to drink her lubricant all before it had a chance to dissolve. Twisting her head, she worked her tongue around the underside of the wooden dildo, encompassing the every minute detail. Sonja worked like a filly slurping and savoring the delicious flavor of a lollipop, working ever so hard to get down to the core.

After only a few minutes, Sonja felt a twitch. Then she felt another, followed by a brutally potent burning sensation deep down in her loins. The sudden onslaught of need caused the mare to squeal. Tears built up into her eyes as she felt the pain amplifying in her vagina and getting much more powerful.

The yellow coated pony plopped back down onto her butt, letting out a desolate cry. She wanted the need to subside, she would do anything to have it go away. Feeling hopeless, she shoved her face into her hooves when suddenly....

Sonja perked right up. She would do anything. And that means anyone, regardless of, well...anything. A devilishly naughty idea formed in the earth pony’s head. Grinning at the simple thought that she could finally relieve herself of this burning passion, brought joy to the teenaged mare. Getting back up, the pony trotted out of her room over to her sister’s door. Cracking the door open ever so slightly, she peered through to notice her older sister was still snoozing. With each breath, Sonja noticed her sister’s sheets were being spread away making way for a minor bulge near her crotch. A naughty smirk creeped over the mare as she quietly pushed her way inside.

Next (and final) chapter coming soon. Stay tuned :D

Chpt 2 - The Solution

Creeping over to her sister's footboard, Sonja couldn't help but giggle at the thought of performing forbidden actions on her older sibling, Malin. The floorboards creaked and shifted under the light weight of the pony's steps. Sonja was torn, on one hoof she needed to avoid detection. The shame that would follow from such incestuous activities would mean that the younger pony would have to hide forever or worse, she'd be banished, never to see the mare she adored so much. Yet, on the other hoof, the mere thought of being liberated from the inferno in her nethers brought immense excitement. Muffled giggling floated around Sonja, trying ever so hard to contain the agitation within her.

The burning took a toll within Sonja, her cunt aching for sedation. Her hooves lightly pressed down on the wooden panels, sneakily making her way over to her sister. The mare's body was her number one rival, metaphorically bloated with arousal, waiting to burst at any chance it could get...

“Mmmpph~!”

Sonja fell to her fronthooves as she felt a wave of marecum leak out from her loins. Moaning softly from the sudden release out of her cunt, Sonja's eyes lit up, bringing her hooves in front of her mouth, letting out a muffled gasp. Worried that her chance to not only relieve herself but to intimately explore a pony that she was related to was ruined, she peeked up from the end of the bed and let out a mental sigh of relief seeing her sister still snoring.

Making it to her destination, Sonja leaned over the bedframe, trying to avoid possible detection. Pulling up the comforter tucked ever so lovingly, Sonja slowly removed the covers from under the mattress, pulling the sheets up to her sister's tummy. Malin had a habit of sleeping on her back, which provided a means of possible entry. Sonja could barely hold back her glee, her eyes taking as much of her sister's soft, firm body as possible. Sonja grazed over the light curves of Malin's build, her vision scampering over the light bulges and through the clear sky blue fur that danced in the ambiance of Malin's snores.

Sonja couldn't believe she had never realized how attractive her sister was. She knew Malin was endowed with...extra parts, but she had never really considered how alluring Malin's body was. Sonja's eyes trotted down to her sister's intimate areas, surveying Malin's sheath with admiration.

And there she saw her sister's pair of plump, virile testicles, dangling from her crotch. Malin's balls were quite large and looked rather heavy. Sonja leaned forward from the edge of the bed, slowly bringing a hoof in to just touch her sister's nuts. Carefully she nudged the protruding sack, amazed by how delightfully warm it felt. She batted at the hanging scrotum like a little filly hoofing at a mobile suspended just out of reach. Sonja’s mind was filled with similar wonder, inspecting her sister's silky scrotum.

While she was prodding at her sister's crotch, a delightful scent wafted into her nostrils. The smell made it's way through her snout, penetrating her mind with a sensual haze. The fact that she was so close to her sister's intimate areas and the numbing pleasure of the smell sent poor Sonja on overdrive. She had to know what it was like. Only in dreams had she been able to realize her lust to explore her sister, but now Sonja had a chance to fulfill her deepest desires. Sonja's tongue rolled out; the young mare's imagination dominated her body, filling it with various scenarios of being graced with the gifts of a stallion.

Saliva ran down the mare's tongue, conforming at the tip. She was lost in a pure, ecstatic fantasy, dreaming of having the erotic skin grind against her oral muscle. She could only envision the succulent flavors caressing her tastebuds as she would paint thick strokes of slobber onto Malin's testes. Drool fell from her tongue, splashing onto her older sister's mattress, leaving a bridge from the impact to Sonja's mouth. Droplets of drool trailed downward, causing the oasis of saliva to expand in size as it mixed with the firm mattress below. Sonja could no longer take it; her body was filled with the need to taste it.

Almost absentmindedly, Sonja brought her nose closer and closer to Malin's testicles. Mere specks of dust separated Sonja from the thick, churning balls. Standing on the edge of the bed's footer, Sonja leaned forward on the tips of her hooves, trying to close the gap. She wanted to shove her snout into her older sister's musk. As she stood on the precipice of the sensual storm rutting her mind, her body lost control of her center of mass, sending her face first into Malin's crotch.

To Sonja's luck, she was able to catch herself before she collided into her sister's erotic endowments. The mare was drunk on the musk of Malin's crotch, wanting to drink up the sexual energy stored in her sibling's appendage. Desire inebriated her ability to think clearly. All of Sonja's sexual burning was constricting her quite painfully, with the solution sitting oh so closely to her. Regaining a bit of composure, the younger pony went in for a lick. She had to do this without disturbing Malin, it was just like a stealth mission in Metal Gear Stallion! Carefully approaching the target, Sonja's tongue extended outward, tip reaching dramatically for her prize.

“Whoa,” Sonja uttered, her mind unprepared for the overload of sensual sensations obliterating her young mind. Her tongue was poking her sister's bulging sack. She could feel Malin's balls move in response to her dripping touch. She watched in wonderment as the teste dragged slowly upward, causing her sister's scrotum to contrast, skin wrinkling as the yellow pony kept her tongue attached to Malin as if it were stuck on a frozen lamppost.

Flesh grinding against the drooling mare's tongue sent a shiver of anticipation blazing to her nethers. Her body begged Sonja's mind to expedite the process. Giving into her need, Sonja gave her sister a few heavy strokes with her tongue, moaning internally as she tasted the delicious flesh.

She pampered the flavor of Malin's scrotum in her mouth, savoring the salty essence as it glided on her thick tongue. Sonja batted at the sensually imbued saliva in her mouth, washing it around every aspect of her mouth. She could feel the mixture sweep up against her fleshy cheeks, brushing like ripples on the beach as the delightful taste dissolved into her salivary glands.

One lick wouldn't be enough for the aroused pony, as she gulped down what was left of her delightful flesh flavored drool-shake. Sonja instinctively hydrated her lips seductively, even though there wasn't any other pony to really take notice. Malin was still sleeping, snoring rather loudly. Yet through the noise, Sonja could hear a faint churning, pressing an ear close to her sister's crotch, she astutely observed Malin's testicles at work. Just the sound of her older sister's seed building up inside the large package sent a trickle of mare fluids down the inside of Sonja's leg.

Lapping at the engorged sack, Sonja quivered as she let the salty skin transpose its flavor onto her. She could feel her sister's testicles sway in response to her delicate strokes, as if a miniature punching bag was fixated to Malin's crotch. Sonja groaned as she took one of the balls into her mouth, only able to get about half of it encapsulated inside. She sucked at the testicle like a filly sucking at her mother's teat. She ravished the salty flavor populating her mouth, mixing in with her fluids, invigoratingly brushing around her tongue before plunging down her throat.

Vapors of Malin's sleep filled arousal occupied the airspace around Sonja's perky snout, as her nostrils worked in overtime to absorb as much of Malin's musk, practically drowning in her sibling's sexual aromas. Sonja was drunk on incitement, her cheeks puckered inward as she heavily sucked at ball flesh, sapping as much of the flavor as she could.

Malin's testicles sweltered under the intense attention Sonja's mouth was providing as droplets of sweat formed around the bulky, curved skin. Sonja worked her way around her sister's ballsack, making sure to give it a thick coat of her saliva before moving onto the second teste. Echoing from deep down the younger mare's throat, energetic vibrations reverberated around Malin's scrotum, the sound waves massaging her swollen glands as they were pumped into her flesh.

If this wasn't paradise, Sonja wasn't sure what would be. Fleeting sensations convulsed through the yellow pony's being. Prior to this moment, she would have never imagined how succulent her sister's dangling bits would taste. She continued her ministrations on her sister's balls, mimicking an enticed filly enjoying a tasty lollipop. An idea cultivated deep within Sonja's mind, she could easily double the fun if she were able to take in both of her sister's testes into her mouth.

The mare stopped, opening her mouth as wide as she could before tilting her head upward to take in her sister's balls from underneath. However, something impeded her chances to take her suckling to the next level.

Upon looking up, she noticed her sister's lengthy cock had become rather excited from Sonja's earlier playfulness. Malin's penis was drooped over her sister's head, the tip resting at the base of Sonja's messy blue hair. Sonja adjusted herself, causing the throbbing erection to slide down her face. A couple of globs of precum burst out of the stallion head, heartily covering the bridge of Sonja's snout.

A giggle wriggled out of the younger mare's mouth as she looked at the thick marecock sitting in between her eyes. A cascading jolt of glee descended down Sonja's spine as her marehood vulgarly smacked together in anticipation. Malin's cock was just lying there, semi-flaccid, waiting for Sonja to indulge herself. Releasing her grip around Malin's ballsack, Sonja just stared at the awaiting penis sprawled upon her head.

“I have got to get some of that,” Sonja told herself, barely muttering the words aloud. The mare nuzzled her sister's sheath before working her tongue along the shaft. Sonja let out a throaty moan as the friction from Malin's rough shaft worked wonders in the young mare's mind. The younger pony coiled her tongue haphazardly around the erect penis, sloppily covering it with a shiny coat of saliva.

Sonja slurped up the emerging pre, wrapping her tongue all around her sister's cock, enjoying the rigid surface of the thick head. Snickering as Malin's cock continued to fill out, growing more erect in front of Sonja's face, the younger mare brought her head a bit lower, preparing herself to feast on some erotic fluids. Admiring the fine sexual treat in front of her, Sonja worked her lips around the expanding member. Suckling at the tip, Sonja grinned as more precum unloaded into her mouth. The taste was rather sweet, which she figured was because of her sister eating so many candies. It was rather intoxicating, flooding her tastebuds with irresistible passion. Sonja's eyes rolled back a little as Malin's musk tantalized her nose. She continued to inhale more of her sister's scent, wanting to savor every bit of it. Sonja wanted more; she wanted Malin to feed her with even more erotic sensations.

The younger mare motioned the tip of her tongue around her sister's urethra before lightly sticking the precipice into the hole. Globs of precum lurched out, being dug up by Sonja's drastic and unwavering tongue movements. Despite her tongue being much too thick to actually penetrate her sister's cock, Sonja's was still content at being able to explore the few centimeters she was able to reach. Tongue twisting eagerly, Sonja cooed as she felt more loads of sweet sensual fluids filling her mouth, mixing haphazardly with her own saliva, swishing erotically in the young mare's mouth.

“Uuuuuugh,” a voice bellowed from below Sonja.

Sonja jumped, unsuspecting to get a reaction from her sister. In the confusion, a trickle of mare juices leaked out of Sonja's pussy, making light pattering noises as they made contact with the ground. Staying as still as possible, Sonja looked at her sister, relieved to see that she was still asleep. Not that it would really matter much, but for some reason, toying with her sister as she slumbered seemed much more exciting to the mare. Yet, she was not satisfied, despite being able to enjoy such a delicious stallion nectar via her sister, her loins were still aggravated. Her nether lips smacked hungrily at an immaterial object, begging to be stuffed with a delectable cock.

While the heat was quite bothersome, the pain was rather manageable up until this moment. Nothing could really pleasure her more than the solution she still had perched in her mouth. Withdrawing her grasp on the erect penis, the yellow pony told herself that she needed to take her sister now. Sonja climbed up onto the bed, leaving an inconsistent trail of mare cum behind her. Carefully balancing herself on her hindlegs, Sonja lowered her crotch slowly, her body teetering from the thrill of oncoming sexual sedation.

“Mmmmmprmph,” Sonja murmured as the tip of her sister's thick stallionhood brushed over her dripping snatch. The cock parted her nethers as she swayed her hips between the swelling endowment. Tiny whispers of pleasure escaped from the younger mare's snout as she felt Malin's penis head drag her pussy lips wide, clinging to her bits. Precum splattered around Sonja's crotch, giving her fur a nice, reflective coat of paint. Despite being immensely heated from her frustration, Sonja couldn't help but relish in lengthy foreplay. Her eyes drooped downward, focusing on her sister's light snoring. Malin's stomach rose as her flare throbbed around her younger sister. Sonja's puffed lips waggled around the top of the throbbing penis that pulsed beneath her.

Still toying with her sister's cock, Sonja shivered as the marecock grinded against her slippery walls, friction resonating throughout her deep cunt. A low hum vibrated through the younger mare's throat, letting the pleasure master her body. “Urk agh!” the yellow coated pony yelped as she felt her sister's cock trying to wedge itself deeper into her moist snatch. To her bewilderment, Malin had started thrusting in her sleep. Panic flushed over Sonja's face. She knew that while her sister fell short of a stallion's size, there was no probable way that she could take Malin's length completely. Sonja knew that Malin was not one to take things slow when it came to sexual endeavors.

To Sonja's misfortune, her body would not yield to her fears. As Malin's pulsating cock continued to drill deeper into her younger sister, Sonja's folds spasmed around the thick stallionhood, holding it tightly. Sonja's pain receptors soon became over-encumbered by the rush of her sister's penis pumping inside her. There was only one way out of this predicament. Sonja took a deep breath, she braced herself for the onslaught of screeching pain that would soon ensue. Pulling against the engorged member rammed inside of her, Sonja silently screamed, her vocal cords unable to produce a sound that could eloquently describe the mix of pleasure and irritation her nerves so rawly transmitted to her brain. Her sister's flare dragged along the crevices of her cunt, trying ever so frantically to latch onto an outlying ridge. But it was for naught, as Sonja had foregone all but the bulky tip of Malin's penis. And despite the waves of pain, Sonja could only focus on the rough attention her clitoris was getting from the stretching of her nethers. Malin's cock stretched her walls wide, as Sonja's nethers fought to keep the member inside.

“AGHHHHHHHHHHHHMRGPHHHHHHHMMM,” Sonja cried in an audial mixture of abrasive carnal pleasure as the stallionhood pulled free from her cunt, hooves flying to her mouth trying to catch the sensual outburst she just made.

“What the hay?!” Malin proclaimed, blitzing upward from her previously napping position, shocked to see her sister exuding copious amounts of marecum onto her crotch.

“ACK!” The younger mare exclaimed as she slipped from the sudden encounter of a now awake older sister. The surprise sent Sonja crashing onto her sister. Sonja's eyes suddenly widened as she felt something rather slippery fill her backside. Her face was devoid of her natural color, a reddish hue occupying her cheeks instead.

Malin sat there dumbfounded, not entirely aware of the events populating her surroundings.

“Uh...M-Morning sis~,” Sonja tried to speak in a somewhat cooled demeanor, “I..uh, see you...oooooooh….like my moves~.” Gyrating her hips, she grinned as she felt her sister's pulsating cock touch every part of her rectum. She could feel Malin's veins thicken and bulge outward, rubbing up against her walls. “Good job Sonja, you recaptured control of the situation”, the young mare murmured to herself. Letting out a chuckle, Sonja grabbed hold of a towel that Malin liked to stylishly wear practically everywhere and wrapped it behind her sister, akin to a makeshift rein. Malin snorted below her, having fallen back to a laying position, tongue draped out of her mouth.

“Oooooooh,” Malin moaned in response, letting the vowels trail outward like a train running on pleasure.

“I'll take t-thaaat as a yess~”

Sonja focused her energy on taking her sister to the hilt. It was a daunting task, but just the concept of the idea of being filled with her sister's precum soaked member was simply stimulating. And here she was, her imagination already unfolding into reality; a thick, meaty horsecock grinding against her walls, pulsating with sexual energy. Sure, any stallion could provide such an experience, but this was special. She was sharing it with the one mare she loved, her sister. That realization sent sparks flying in Sonja's head, she wanted to ride this one out until the end of time.

Pumping her hips, she squeezed and grasped at the bulky penis with her muscles, holding onto every inch she could keep inside of her. Malin continued to groan from the sensual stimulation, shooting globs of precum into her sister's mostly dry anus. Sonja's walls absorbed the slick sexual fluids, rejuvenating around the heated cock that throbbed in tune with the blue mare it was attached to. The flare vulgarly stretched Sonja's rectum wide, allowing for just enough space for the medial ring to enter the young pony. Sonja gasped at the feeling of being almost torn open, yet she was quite amused at the fact that she felt very little pain from this encounter.

“Ffffuck you are thick, sis,” Sonja howled in delight.

“N-noo swearrrINGGgggggg,” Malin rectified her sister's outburst even through their incestuous actions, her cock explored the depths of Sonja's curvy plot. Malin had never actually realized how enticing her sister's ass was before this taboo bonding moment. The way it smoothly arced, the fluffy fur dazzled in the bedside lamp's glow, and how deliciously plump it looked.

Grasping onto her sister's plot, Malin gave Sonja's butt a soft, firm squeeze, causing her sister to eep in surprise. Sonja pistoned her way along Malin's cock, continuing to work increasingly more inches into her ass. As Sonja would withdraw, Malin would embrace her sister's butt cheeks together, keeping a tight grip her endowments. Sensually massaging the plump ass, Malin moaned as Sonja clenched her muscles together, keeping the cock inside her like a vice. In response, Malin dug her hooves deeper into Sonja's skin, tracing circles around the fur adoring the stout plot. Marecum spilled out of Sonja's vagina, splattering onto Malin's crotch, dripping down to soft, hefty balls spread out on the undone bed.

Malin could feel her own anus clenching as if she was shifting places with her sister, in a sort of tantric link between the two siblings. Her own rectal walls grasped eagerly, as if they were being penetrated by a phantom penis. Malin could feel Sonja's burning flames of arousal encompass her own body, igniting her sexual organs tenfold. Malin thrusted wildly in a sexual frenzy, shoving the marecock deeper, feeling Sonja's crotch connect with hers. They were no longer Sonja and Malin; they were one. The purest form of sibling connection, brought together by sisterly love. Sonja's cunt spasmed wildly, firing bursts of her mare nectar onto her psuedostallion. In a final crescendo, Sonja slammed her plot onto Malin's torso, spreading marecum onto both of the sisters.

The elder sister's mind was being seized by thoughts of actually experiencing such unacceptable actions with her little sibling. Such ideas that her sister would be so willing to fuck her while she was sleeping caused Malin to teeter on the precipice of release. Sonja continued to spill her cum out of her pussy, her nethers leaking with reckless abandon. Tugging on the makeshift towel reins, Sonja hoped to edge her sister to follow suit. She wanted her sister's fluids to fill her, to paint her innards white with stallion seed. Flare expanding, Sonja howled as she felt her sister finally reach her climax.

Time almost stood still. A noise penetrated the erotic misty air. Throb. Throb….throoob.

“Sonja, I'm going to mmmmmmpppppph~,” Malin wailed as she gripped her younger sister's flanks tight and shoved her cock ever deeper inside Sonja's plot. Sonja moaned as she felt her sister unload strand upon strand of thick stallion seed. Malin's cock throbbed as the cum bolted out of her cock, the liquid surging through her urethral tract, before firing deep within Sonja's ass. The hot carnal liquids flooded the younger mare, her belly slightly bulging from the cum churning out of Malin's plump testicles. Sweat beads dripped from Sonja's head, showering her older sister in a sensually induced rain.

“Ohhhhh Malin, fill me more~,” the adolescent pony begged, feeling Malin's cock continue to spasm inside her anus. Malin practically didn't have a choice in the matter as her balls continued to empty themselves into her sister. Malin caressed her mare's flanks lightly, gliding her hoof through the soft yellow fur that she ever so adored. Unleashing her grip on the towel, Sonja moved her hooves to her slightly bulging belly, rubbing it as she felt her sister's seed build up inside her. Malin's cock sputtered out a few more thick strands of cum before Malin's climax had finally died down.

Sonja collapsed onto her sister, causing her miniature cum belly to morph around Malin's body. Both of the sisters were exhausted from their sexual adventure, now baking in the remnants of a passionate, yet hazy afterglow. Cuddling up to her sister, Sonja wrapped her hooves around her sister before drifting off into a post sex nap. Bringing her hooves up to her sister's blue mane, Malin rubbed Sonja's scalp, humming an old tune their mother used to sing to them when they were fillies. Sonja softly cooed in her slumber, enjoying the affection from her sister.

For that was the day they had discovered the true meaning of sisterly love.
