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.
