Chapter Only

From the darkened clouds, snowflakes continued to listlessly fall, piling mounds of fresh white powder atop the thick wooden rooftops of a tiny pony community and the spruce trees that dotted its surroundings. The overwhelming layer of white stretched away as far as the eye can see, and the only colors that broke away the monotony came from the wood that made up the houses, and what meager flora one could find.

Located in the frozen north, far removed from the borders of bigger civilizations, the inhabitants of Snowpit were subjected to the oppressive weather on a daily basis. But, they had long since learned how to coexist with it, living in harmony in their warm, tight-knit group of family and friends. While some of the wonders of the modernized world had already reached their doorsteps, both broadening their horizons and making their lives easier, life in Snowpit remained much the same. Everyone in there was satisfied with their lives, which was as sluggish as the falling snow.

From the door of one of the cottages, two ponies hurriedly exited the cozy interior—quickly closing it shut to not let the chilly air inside. One of them was a mare that wore a light blue sweater that didn’t suit the outside weather very well but that accentuated her figure, and the warm smile that she wore made the cold feel less bitter. Contrasting her, the stallion next to her gave off chills that prickled under the fur; his height surpassed the doorframe, he was covered from top to bottom in heavy winter gear, a mask covered his muzzle and a pair of snow shades both protected and obscured his eyes.

“I’m so sorry about my little brother,” the mare said, frowning apologetically. “He normally behaves better than… that.”

“It’s okay, Snowy” the stallion quietly replied with a chilly voice. “I’m sure he meant no harm.”

“Oh gosh, did it hurt? I’ll go grab you some cream, you shouldn’t go out with a burn,” Snowy said, reaching out her hoof towards the stallion’s face.

“I’m fine. Soup doesn’t singe as badly.”

Despite what he had said, the fussy mare reared up on her hind legs and checked his face. Her hoof parted his thick fur looking for burnt spots, but all she found was the reddish tint of his cheeks warming her touch. Relieved, she sighed and put his mask back on. His cheeks tried to chase her tender hoofs when she pulled them away but snapped back into place when he realized that he wouldn’t be getting any more attention from them.

“Again, I’m so, so sorry -”

“It’s fine,” he insisted.

“I-I don’t know what provoked him. He never lashed out like that before.”

“Foals can be like that. He’ll open up eventually,” he said. “Maybe I can bring a toy for him by the time of our next date? That outta ease him up.”

“Next time..? Oh, Trail Blaze, I… I mean…” caught off-guard by his offer, Snowy stumbled on her words. “Tonight was great, I’m glad that you got along with everypony… Besides my brother, that is…”

“Your father’s a really funny guy,” Blaze complimented.

“Don't encourage him, he says too many jokes as is. But what I’m trying to say is-”

Her words hitched on her throat when she saw the hopeful, almost pleading look on the stallion behind the mask. It pained her to do so, but it would further harm them both to continue like this.

“It won’t work out,” she blurted suddenly. “We won’t work out, I mean. You’re a lovely stallion, Blaze, and I loved every single one of our dates, but… But you’re never here. Being together with you on my family table made me realize that… Whenever I feel lonely, I wished that you were around. But you’re always someplace else. And I want somepony that’ll stay here… with me.”

Trail Blaze’s disposition crumbled as soon as those words left her mouth; his eyes and ears lost their energy and cast downward, sagging as if they weighed like concrete. The mare couldn’t muster the strength to look him face to face, it hurt her as much as it did him to end things like this, especially after such a good night that they had together with her family.

“Are you sure you can’t stay?” she asked followed by a short silence. “I don’t know, maybe you could do your deliveries nearby and come back more often, or let the mayor build you that postal station that he offered you and your sister. I can’t see you when you’re away when I need you most.”

Trail Blaze promptly shook his head. “Sis can’t do all of our work by herself. Somepony needs to deliver mail between places far out there, and if she tries going alone she’ll get lost, or worse. She’d go regardless of her safety, she’s that kinda mare.”

“Well, somepony else could do it! You two don’t always have to do everything alone, you have your own lives to live!” Snowy argued, raising her voice for a moment which surprised even herself, embarrassed by her outrage she clapped her mouth with her hoof.

“We’d still have to wait for somepony else to step up. Until then, those ponies would have their delivery chain scattered up. And I don’t think I would be able to sit still for long, either.”

It seemed that there would be no middle ground for them to meet, as unfortunate as it was. Saddened by the way things were, both ponies silently stood still under the porch’s roof watching the snow slowly trickle down. Slowly, they walked up to each other and huddled up in a tight hug to enjoy the comfort of one another one last time. Neither knew how long the moment had lasted, but Snowy was the first to break off the contact.

“Let’s stop here. I don’t want to lead us on any more than this,” she lamented, moving inside the door’s frame whilst looking at the ground. “Thanks for everything, Blaze. If you ever decide to settle down somewhere near, come pay me a visit… Alright?”

Snowy gave her now ex-partner a final forlorn look before closing the door behind her. Blaze didn’t linger at her doorstep, his hoofs trotted through the layer of snow away from the house without looking back. His head was blank, he really thought that he had found the one this time around; the disappointment and sadness which afflicted him were painful to bear.

Most of the villagers were indoors when he passed by their houses, and the few ponies who were gazing from inside their houses saw the huge stallion that delivered their letters walking through the village, his head and shoulders hunched over as if he were carrying a heavy load on his back. As friendly as the villagers were, nopony came out to greet the sullen Blaze.

Blaze slowly but steadily navigated through the snow-coated cottages and found himself at the dinky town office, which doubled as the post office. Like Snowy had said, the mayor had offered the siblings a building for them to manage their services, but much to his displeasure they had declined his offer, saying that making a building that would be used so sparingly was a waste of resources. Him and his twin sister were constantly on the move, which suited them fine. He knocked at the door twice, hunched over to fit the door frame and let himself in.

“Who is it? I’m busy- Oh, it’s you,” the mayor grumbled after being disturbed from his work.

His desk was filled with letters written in cursive - Blaze wouldn’t be able to decipher what they said even if he spent the afternoon looking at them; it seems like their delivery brought him a big stack of papers from the other settlements. Most of them were just minuscule outposts that barely surpassed the 300 population cap, but nevertheless each one still had to go through the bureaucratic circle.

“What have I told you about keeping the doors closed? I don’t want the wind blowing anymore of my paperwork! Tch, these damn Yaks… hard headed as always. What I wouldn’t give to get them out of my mane…” the mayor complained as he nursed the remains of a cup of hot coffee. While he rubbed his temples, he poured himself some more with his magic and emptying the pot. “By the way, we’re fresh outta coffee, so if you want some, you’ll have to get it somewhere else.”

“Where’s sis?” Blaze tiredly asked.

He wasn’t interested in the hot beverage, not after the meal he had not long ago. If unlike him his sister had a better night, he’d go straight to the spare room they had at the office and crash for the night. And if not, which he hoped wasn’t the case, she’d be in the mood to move out.

“Trail Lead? She’s out in the back with your nasty mutts. She walked in not too long ago, looking like you did just now,” he harrumphed.

Unfortunately, it seems like her date ended as well as his.

The mayor’s mean comment didn’t aggravate Blaze. By now he was used to having ponies getting scared of his dogs, and he knew that they didn’t mean ill will towards them, that they simply reacted to their fears. He didn’t meet them eye to eye, but he understood that they made everypony else uncomfortable.

“I’ll be going, then. Goodbye, and see you next time.”

“Be careful out there. Oh, and don’t parade your mutts near the houses, I’ll never hear the end of it if you both do that again,” the mayor answered without looking away from his papers.

Blaze nodded the mayor goodbye, hunched over and went outside. After rounding the corner twice he found his sister laying down on the ground, unbothered by the snowflakes falling on her and absentmindedly drawing on the ground. She wore the same heavy winter gear as her brother, which was commonplace for the siblings. Their timber dogs were unattended, but thankfully they were sitting patiently, awaiting for their owners commands.

They were a bit different from the norm - somepony or something crossbred traditional sled dogs with timber wolves, resulting in their four companions. They were covered with wood and branches like their wild parents, but there was some fuzz around their body and beneath their wooden carapace. The twins picked them up because they seemed perfect for their job: they only required to be fed once in a while, they could run for hours on end without a break, and most importantly, in the twins opinion, were the cutest breed they’ve ever seen. It was a shame that most ponies were afraid of them due to their wild-like appearance.

When he approached, Lead’s ears swiveled at him when she heard his hoofs crunching the snow, but otherwise she continued to leer at her drawing. That she didn’t greet him or speak up at all wasn’t a good sign, if everything had gone well for her she’d be gloating about her success and at his throat asking for details about his date.

“Hey,” he said. Their dogs greeted him back eagerly, circling around him, rubbing their barks on his body and barking up at him.

“Hey,” she answered with as much enthusiasm as her twin. She added the final details of the yak she made on the snow, then blurred it all just to start over from scratch.

“You wanna move out?” he offered her. By now the dogs were running in circles around him, and he petted them one by one.

“Mmm, yeah. I already picked up the mail, so prep up the sleds,” she told her brother and shoved snow over the space where she was drawing. “Eeny, Meeny, Miny, Moe, get in line.” she barked the order to the dogs, which promptly stopped playing around and got into position. They obeyed and understood every word that she spoke, as if they spoke the same language, something that amazed Blaze to no end.

Lead’s left hind leg shook as she sluggishly stood up, she grabbed the dog’s equipment and started to prepare them for their trip to the next village over. If not for her feminine voice, ponies would mistake her for Blaze; their colors were only a few light shades of brown different from each other, and the few inches that she lacked could be overlooked by her still massive size. Even their dogs, crossbred with wild timber wolves, couldn’t compare to their height; it was only due to their strong barks and genes that they were able to carry the siblings around.

It didn’t take long for the professional mushers to prepare their cargo, the middle cart held the mail and supplies from this and other hamlets they had passed through that needed to be delivered, alongside the necessities the twins needed for surviving the trip. In the far back stood Blaze and Lead side by side, she was to the right commanding them while he stood on her left, keeping track of where they were going.

Soon enough, they were leaving the settlement behind and driving deep into the panorama of white.

It had been many hours after the twins had left the settlement behind, but the vastness of nothing still prevailed much of the terrain in front of them. The four timber dogs ran tirelessly through the permafrost with Lead’s guidance while Blaze told her when to turn and where to go.

Blaze’s mind dulled all the while he scanned the horizon; the scenery barely changed, if ever. Some snow here, a rare collection of bushes there, slopes up and down and infrequently a marked rock or two. The vastness of empty land uninhabited by ponies or other creatures enamored him when he first began his career, but now after a decade and a half crossing this frozen desert, he and his sister were unimpressed by it.

Usually by now the twins would be taking advantage of their complete privacy to gossip and discuss every juicy and raunchy topic that occupied their heads, but neither of them would speak up this time around. The distressing quiet only served to fuel their depressive state; only the rushing of the wind and the occasional bark echoed around them.

Both were feeling depressed but neither were brave enough to be the first one to ask the other about the elephant in the room, despite their curiosity.

“So… How was your date?” Blaze hesitantly asked after he couldn’t take the silence any long.

“I w-w-want a coltfrieeeeeeeeend!” Lead bawled out as soon as her brother asked her.

There it was.

“That bad, huh?” he shook his head.

“I’m so lonely, Blaze! Do you know how long I’ve been single?” she cried as she burst a dam from her eyes.

“Since… second grade?” he slowly replied, trying to spark a memory.

That was a lie - as far as he knew she never landed somepony to date seriously, like him. Still, it would be best to amuse her with a guess and hope that it would lessen her hysterics.

“That didn’t count! We only held hoofs!” she held Blaze’s hoof tightly and wrung it deep into her chest. “Oh, I should have kissed his chubby cheeks while I had the chance…”

That she did have a little schoolyard crush actually surprised him. He wishes that he had that, at least.

“Well, what happened this time? Did he try to pump and dump you?” he asked curiously.

“Not even! We had just gotten out of a diner and he broke down in the middle of the road, saying some bullshit about how he thought he could handle a big mare like me, but that the pressure was too much for him. He-h-he said that I was more massive than the biggest yak he’d met!” she cried once more and thumped her head against the front of the sled. “A yak! A big stinking yak…”

“That wasn't very nice of him.” Blaze furrowed his eyebrows. “D you want me to 'forget' his mail during our next round?”

“Do whatever you want. I don’t ever wanna think about that asshole again. Pretty sure the entire neighborhood heard me cussing him every name under the sun, too.”

Lead continued to cry messily, blowing her nose on the hem of her attire. Blaze hugged her and stroked her head, while he elaborated ideas for revenge; it was one thing to break up with his sister and another to make her cry like this. Her tears eventually slowed down to small trickles after she mellowed in the comfort of her brother’s chest like a kitten.

When she regained enough of her composure to stand on her own, she asked her twin with a slightly hoarse voice: “So what about your date? Snow… Icy Heart or whatever. I swear that filly had hearts in her eyes whenever she was around you.”

“Didn’t work out as I had hoped.” Blaze admitted in a crestfallen voice.

“No duh, I want to know why! You guys have been flirting around like middle-school foals for the best part of a year now, and then bam! You guys break up. What, did she cheat or something?”

“No, she wouldn’t do that to me. She really liked me, but she said that she wants somepony who’s around more often than I am,” he mumbled, his head dropping low when he recollected her words.

“Oh, not this shit again,” Lead clicked her tongue. “Fuck’s sake, we’re never gonna find somepony at this rate. Why can’t they understand that our job is extremely important and that we can’t just quit on a whim?” she complained, grabbing Blaze’s head and caressing him on his mane and behind his ears.

“I’m never gonna get a marefriend at this rate…” Blaze mewled, burrowing his head further on his sister.

“You’re a handsome colt, Blaze, it won’t take you long to snatch a cute mare.” Lead reassured him.

“Thanks, Lead. Don’t let that comment drag you down, either. You’re prettier than any Yak.” he mumbled amidst Lead’s chest fluff.

The twins vented to each other as per routine. Try as hard as they might, every chance they attempted in courtship ended short, and with no one else to complain to they had grown used to using each other to pour their frustrations on. Actually, it was because they were so close to each other that they let themselves act like needy foals on a daily basis.

They were attached to the hip as far back as they had gotten their cutie marks when they went on a secret trip between two neighboring villages. Lead rushed ahead making rapid progress with their old family pet while Blaze made sure to remember whatever landmarks he could to make the trek back. Their parents were as mad as they were proud.

The sun signified that it had been a few hours that passed by while the twins chatted idly, and before he knew it Blaze caught sight of a tall stone cairn with red markings surrounded by smaller rocks in the corner of his eye, a clear handiwork of his that helped them navigate throughout this unremarkable area.

“Hey, we reached the fifth stone. Should take about two days to get to Little Grove.” Blaze shook Lead, warning her about their location.

“Another quick trip to Little Grove, then. Let’s set up camp, I wanna go to bed before the sun sets.”

Lead barked an order to the dogs, and they slowed down their sprint until eventually the twin’s expedition skid to a stop. There wasn’t much importance as to where they settled, since this plot of frozen earth wasn’t much different from the wasteland around them.

Both of them stepped down from the sled and unmounted their equipment, Lead doing so more slowly than her brother due to an ache on her hind hoof. They picked out their tools and chose a spot that seemed good enough to set up camp, as having a good night of rest can drastically improve their chances of arriving on their destination unfrozen.

Blaze dug his shovel on the old snow and sighed in relief. He had made sure that he shoveled enough around the outside edges of his tent to avoid the biting freezing air won't seep in the middle of the night; all it took was for them to forget insulating their tent properly one time for the twins to have a damp and freezing experience that they wish they could forget.

Nodding to himself after inspecting his work, Blaze went to his dogs and petted every single one of them goodnight; they were made to sustain these types of below freezing temperatures, so they wouldn’t have a need to go inside his already claustrophobic small tent with him. He had tried that when he was a colt and it didn’t end up well for anyone, turns out that stoves running on wood spooks timber wolf half-breeds greatly.

Blaze stepped in and zipped the entrance to his temporary abode shut. It had barely enough space for him and his sister to move inside, but it meant that both benefited from sharing the heat from their stove equally. Lead was already basking on its warm glow, now completely cast off of her outside clothing and now sporting a fuzzy pair of socks on her four hooves. Her muted brown coat and dark mane were thick and cozy, perfect for the type of weather they lived under during the whole year.

“Lead, have you seen my socks?” Blaze asked as he undressed, throwing his heavy winter overcoat next to his sleeping bag.

“You put it in my bag by mistake, it’s in there.” She pointed over while still facing the small stove. “Hope you didn’t jerk off with it, I don’t wanna sleep with your crust rubbing on me again.”

“It was only that one time...” he mumbled in embarrassment.

Blaze traded his snow boots for his mismatching pair of socks - a tacky gift Lead got him as a joke that grew on him once he realized that they didn’t retain much of the humidity when they were out on an expedition.

Besides a couple of books, the twins didn’t own many possessions. Every extra little thing meant more weight for their dogs to carry and less space in their sled, so they went day by day without much other than each other’s company. Which worked just fine for both of them, as they grew without much attachment to material goods, they found joy in their job and that was good enough for them.

He sat down in front of the stove, side by side with Lead and outstretched his hooves to thaw out some of the cold that grew on him while he was outside. Once he warmed up his limbs, he leaned onto Lead and rubbed himself on her, she reciprocated the feeling by hugging him tightly with their cheeks next to each other.

“Did you check the snow outside? I don’t want to wake up all wet and miserable again.” she quietly asked while cuddling up to him.

“I did, all’s OK. You sure you don’t want me to heat up some food for you?” Blaze offered, rubbing their cheeks together.

“I’ll cook something up tomorrow morning, I just wanna snuggle right now.”

“Same.”

The faint fire combined with each other’s body heat was sufficient for the twins to bear the chill of the inhospitable tundra. Any and all reservations that they otherwise would have towards feeling each other up died decades ago; their bodies grinded intimately on one another, satiating their loneliness even if slightly. Lead put her head under her brother’s chin and mumbled softly:

“Why is it that nopony will stay with me? Am I not pretty, Blaze?”

“You are, Lead. I think… I think Snowy Heart was right. We’re always too far away from everypony that we try to date, they miss us.”

“That’s bull. What can we do about it? This is what our cutie marks tells us to do, it’s our lifeblood. I don’t wanna quit traveling… But I also want a husband to come back to.” Lead grumbled, rubbing against Blaze’s neck.

“We’ll find somepony more patient. We just gotta keep trying.”

Lead gave off a prolonged sigh and slid down on the ground sheets. Much like a cat, she crawled in between Blaze’s legs, leaving her lower half hanging in front of him, and nestled her head in between his thighs. She caressed his belly with her muzzle, grinding it all over his overgrown coat as she traveled further downwards until she reached a pair of warm and furry orbs that hung tightly under his sheathe.

“I was going to spend my night sucking on somepony else’s balls, it’s not fair.” Lead complained while holding Blaze’s pair in front of her eyes like a pair of glasses.

“And I was about to suckle a nice pair of teats tonight, it isn’t fair one bit,” he mewled, laying down on her sister’s rump and caressing his face on her hips.

This, too, was a part of their routine; what intimacy they lacked, they found with each other. It wasn’t strange nor something to mull over, they just did it and it was natural for them.

“I want to get my insides stuffed full, is that too much to ask?” her tail whipped, fruitlessly trying to vent off the glow in between her cheeks. It had been far too long since it had seen any action, and the itch made sure she remembered every day.

“I had been looking forward to rail on her for so long, and it didn’t even work out.” His head lowered to her cutie mark, where he rubbed at with his head on one side and with his hoof on the other. He liked how soft she was in the trunk, there were often times where he’d find himself nodding off when he leaned on it.

Lead’s nose fondly nuzzled her brother’s balls - fluffy in all of the ways that she liked, not that she had much experience with different ones. They emitted a heat that made the mare all giddy, making her eager to fondle them further. She didn’t know when she had gotten a fixation on those jewels, but it had been a long time now that she used them to help her decompress her sexual frustrations.

She traced all around them and then upwards until she booped the entrance of his shaft, where the tip of his penis had erected out by an inch. Blaze had never been shy about her touching him like this, and neither did she; they always felt relaxed when they explored each other.

Relaxed, and aroused.

“Hey, since we’re single again… Wanna fuck?” she bluntly asked. “It’s been a while.”

Seeing his shaft expose itself to her during their intimate bonding ritual never failed to make her happy. The way it throbbed and grew caused blood to rush to her cheeks and her nethers to start to drip.

“I was afraid that you wouldn’t ask.”

His response was accompanied by a bite on the side of Lead’s flank, garnering a gasp from her. It had been a long while since she felt somepony else’s touch - or more specifically, her brother’s - if he were to tease her as he usually did, she wouldn’t be able to hold herself back from rutting like animals all night long. She both cursed and thanked the stars for him finding out that she’s into biting.

He coaxed her to lay on her side and lifted her hind leg, revealing her dripping vulva and fat, succulent teats. Those big mounds of flesh always awakened a deep desire within him to suck on them like a foal, the fact that his sister’s were so invitingly big was his biggest weakness. Blaze immediately started to bully her nipples, nibbling on both of them at once, not letting them go even after they had gone as rigid as the frost outside the tent.

“Fuuuuuck… There’s no milk in them, you know? Don’t stop though,” she breathed.

Lead bit her lip and plunged her muzzle on his sack, breathing in deeply the musk that hung on her brother’s balls - the familiar smell instantly made both of her lips to drip. She began to exhale from her open mouth, from where her tongue hung loose, as she breathed in more of his salty scent, occasionally trying tasting him. The only things in her line of sight were his growing rod and hanging ball sack, the latter which she greedily put inside her mouth.

“Look who’s talking… My balls don’t have any milk in them either.” Blaze moaned, releasing a breast to tell her.

“Lies!” she accused him. “You’ll be giving me plenty of milk in just a sec.”

Blaze snorted once he felt the wet sensation envelop him, he had missed that tongue of hers fiercely. Every time that they fucked each other or whenever she was going through a stressful situation, she always dove face first towards his sack; he couldn’t deny, the sensation had grown immensely on him. Not about to leave his sister hanging, Blaze suckled on her bosoms - gently at first, licking and playing with her nipples, then sucking them hard while pulling them, drooling all over the blankets they had laid out.

Lead, meanwhile, did just the same with Blaze’s balls, pushing and pulling them gently in her maw as her tongue relentlessly licked both orbs as if they were the sweetest candy she ever had. She reached her hoof upwards and with the soft groove of her frog jerked his meat up and down even after it had gained its full length. She released his balls from her mouth with a loud pop, only to put them back in for another round whilst she continued to massage his tensing meat.

“Aaah- Somepony’s hungry tonight- Hmm-” Blaze groaned.

The mind-numbing sensations on his shaft provoked Blaze, he wouldn’t let Lead do him like this without a rebuttal. Blaze clamped down his teeth around her areolas then pulled - like a hungry wolf tearing off stripes of meat. He could feel her nipples getting even harder as he left teeth marks all over her boobs, and her tail whipping his head repeatedly.

A cry broke out from under him, it seems like Lead was complaining about something, but to her dismay her stuffed mouth garbled her words. Despite her protests, Blaze didn’t stop, hardening his grip on her tender flesh, electing more muffled cries of agony and ecstasy from the mare; he was almost sure that he heard the word cheater at some point. Her reluctance to let go of his jewels put her in a state of despair, she wanted to curse at her brother, but couldn’t, and thus had to resign to her pleasurable state.

As deep as Lead’s fondness was for Blaze’s sack, she wouldn't let him bully her like this without retaliation. With much reluctance, she spat out his sack, now completely drenched in her drool which still had a few strands connecting to her mouth. She flipped to the side and laid on her back, grabbed Blaze’s hips and positioned them in such a way that his cock was pointing at her face.

“Stick it in, you asshole,” Lead gasped. “Do it or I’ll bite you to-” she was promptly silenced by the tip of his cock inserting into her mouth.

Blaze could only exhale loudly through clenched teeth as he slowly lowered himself into his sister. By now she was a pro at taking on his girth, so he ignored the gurgling sounds that came from her and proceeded to go down until he hit his medial ring at her muzzle.

Lead’s vision was breathtaking, when her brother’s cock reached the peak inside of her bulging throat, his hefty wet orbs would flop against her nose and splash some spittle on her face. The sensations too were to die for, the delicious hot lance shoved down her mouth did more than fill a spot, it squeezed her and made it difficult to breathe, and then his maw pinched and bit and gnawed of her sensitive teats like the wildest newborn she had ever seen.

His sister’s tightness wasn’t something to be taken lightly. Her tease accentuated by weeks of blue balling and now her snatch of a mouth was going to make him explode. He greedily suckled her as if her teats were hiding a precious pool of milk, sucking and pulling one, then the other. The more desperate his mouth was, the faster his hips moved, filling the tent with the moans and gurgles of his twin from his full assault.

Out of the blue, his balls couldn’t hold onto his seed any longer, and shot out his hot load inside Lead’s mouth, who wasn’t prepared for the hot spunk and proceeded to gag and cough badly. Lead pulled her head to the side for some air and Blaze’s cock drooped over her face. Blaze wasn’t finished however, and more of his white essence shot at her face and chest, painting her upper half with white streaks that warmed her with his love.

Only then did Blaze let go of the pair of breasts, hungrily gasping for air after he wrestled with nipples the entire time he fucked his sister’s maw. Blaze recovered from her hacking after a while, wiping her the cum that donned her face and body and bringing to her nose to take in the smell of a stallion. Once the scent reached her brain, something clicked in her head.

After sensing Blaze’s body shifting under him, Blaze sidestepped to give her some space to breathe in. She immediately stood up onto her shaky hoofs and reared up, flung her tail sideways and pushed her rump onto him.

“Stick it in, fuck me, come on, stick it in Blaze, break my pussy, fuck me!” she begged with labored breath.

It has been a little while since they’ve gotten laid.

Blaze immediately sprung into action, throwing himself over his sister and locking his fore hooves on her chest. Their searing sexes kissed and mashed against each other as Blaze struggled to find the opening - any of them - to thrust inside.

“Come on! Put your cock in my pussy already, goddammit! I want your dick!” Lead screamed, pouncing her hips backwards at Blaze, not helping him find his mark.

After much struggle, Blaze’s flared head managed to find the entrance to her soaked nethers after prodding her winking clit a few times, and slid right in. There was no struggle for him, welcoming him back to this familiar place. Soon after, the head found - and kissed - the entrance to her womb. Twin brother and sister connected in the deepest parts of their core.

Lead’s eyes instantly shot up, she bit her entire lower lip and voiced a deep grunt that lasted a minute. She missed - no, craved his cock. Every night she held out while he was dating from the other village, and every night she required the attention of her hoof before she could sleep at all, worse yet was that there wasn’t a night where he wouldn’t stroke his thick cock. His bedding stank of his semen too, furthering her hunger. She had tried and failed to find somepony to call her own in the meantime, but the more she waited the more she missed the feeling. Now that both were free, she would make sure to capitalize on every moment she could to get a fill of his cock.

“Fuck… Mmmmf- Sis… Your cunt’s tight…” Blaze moaned in between bursts of breath.

Their hips met each other over and over again on an passionate pattern, when he reared back for his next thrust she also went forwards as to scrape more and more of his member inside of her, both smacking back into each other with a thunderous clap, jolting their members with absolute pleasure. Her walls clenched for dear life whenever his cock tried to pry over her womb, modeling her folds after his erection before it shoved back and back in to repeat the process again.

“Aaah~ Aaaah~ I love your- ah~ - your cock Blaze, fuck me hard, fuck your sis- Eep!” Lead got cut off when his molars clamped on her ear.

It had been hard for Blaze the past couple of months, his sweetheart was always in her little house away from him and the temptation that was his sister wouldn’t stop masturbating right next to him every night. He would always end up copying her and stroke himself to sleep, while the smell of her aching pussy wafting over his nose. Whether or not she was aware of that, he didn’t know. At the end of the day, he wanted to fill somepony’s cunt full of his seed; while he wasn’t happy that things didn’t end well with him and Snowy, he was going to make sure to cum inside his sister every day until he found a new mare.

Blaze’s hips would continuously speed up, eventually reaching a point where Lead couldn’t catch up with him anymore. Her hole was being stretched at such a fast rate that they both started to heat up and forget the cold outside; the loud impact when his sheathe would smack against her rear mixed with their screaming and moaning deafened the shrill of the wind that bounced off the walls.

“Aaah-” thump! “Aaah-” thump! “Aaaaah-” thump “Fuck-” thump “Fuck meeee~!” thump - “Breed meeee~”

He would.

Blaze’s body shifted, pushing Lead to the ground. His hips moved at breakneck speed, splashing her leaking juices all over the place, his pelvis beat her clit whenever their bodies smacked each other making her gush more mare cum.

“You’re too tight- I’m gonna fill you up-”

Their hips locked in place, refusing to let each other go. He pulsed deep inside of her, shooting so many loads of his spunk in her uterus that it threatened to burst. When there was no more space, it spilled out, mixing with her own cum which burst from within her across the tent. Both of their thoughts were completely gone, the orgasmic bliss that they were in turned their brains into putty while Blaze continued to fill his sister with more and more of his seed.

When it subsided, the twins fell atop of each other, their legs had been too tense from their bonding. They panted and moaned while they recovered and restarted their brains; but even when they did, they remained close to each other, cuddling while basking on the sweet afterglow, their genitals a soapy mess of jizz and mare cum.

“Blaze?” she called for him with a tiny voice.

“Hm?”

“We ruined our bedrolls.”

He looked at them, and as she said they were all wet from their adventure. If they were to sleep on those, they wouldn’t have a pleasant experience that night.

“Fuck.” he exclaimed quietly.

“Yeah. We’ll fuck, til the sun rises. Got more energy in that dick of yours? My cunt’s aching for more.”

He did.

Mornings tended to come rather early in the frozen north; the sun crest the horizon and monopolize the skies for over two-thirds of the day. Sunshine had already filled the inside of Blaze’s tent from the half open flaps, but he continued to sleep undisturbed. That is, until he heard a noise from outside, right on the other side of the tent, waking him up.

As much as Blaze would have wanted to stay asleep, he and his sister had a schedule to keep and they were already late on it. What should have been a pleasant two-day ride towards Little Grove extended itself after the twins spent every single moment to rut like animals.

They could barely get a wink in the morning after they fucked themselves to sleep, with their dogs barking and clamoring for attention and food. They would begrudgingly get out and prepared their meals then crawled back in to get some rest. That’s why they decided that they would only fuck once that night so that there would be time to recharge. They did it twice.

Blaze reached his hoof out to shake his sister awake - as he usually was the first one to wake up - but felt no body under her sheets. He blinked a few times to adjust his eyes to the brightness and all that he could see and hear something shifting and grunting outside his tent. One- two- three shadows, two mediums and a big one. It seems like miracles do happen because Lead was already out and about. That succubus of a sister that he has drained all of his energies last night.

The smell of coffee graced his nose while he dressed up, Lead must’ve prepared his cup while he was still asleep - he thanked the stars for having been blessed with such a great sister. Blaze was surprised that he managed to sleep over the sounds of their dogs barking them awake, Lead preparing his breakfast and the grunting right outside his door. He idly wondered if she had any troubles preparing everything with her leg bumming her this early in the morning.

Unzipping the tent, he made his way out to check on everyone else and pour himself a coffee that Lead had prepared. Only their sleds and equipment were there to greet him, not Lead nor the dogs. Still fighting the morning daze off of his brain, Blaze remembered the commotion on the other side of the tent and decided to investigate. Sure enough, there was Lead and their dogs. He yawned, sipped his drink and sat down.

“Couldn’t wait ‘til I woke up?” he asked her.

He was too tired to be able to understand her muffled reply. Two of the canines were tag teaming her - one in the front and another in the back. One neon green cock dove all the way into her greedy pussy, the knot would part her lips into a spherical shape as it went in and out, spilling the cum that was already inside of her onto the ice. The other she sucked like a Popsicle, it was certainly narrower than his own shaft so it wasn’t much of a challenge for Lead, but she still blew it with a gusto that only a slut could muster.

This also wasn’t out of the norm. It didn’t happen often, but it wasn’t unusual either. Being out in the middle of nowhere with nopony in sight meant that they both got to experiment lots. With each other, and with anything and everything that they could get their hooves on.

It seems like she already finished one of them while Blaze was still unconscious, Eeny looked like he was quite content with himself while Miny looked eager to join the party, his red rocket dripped and begged for attention. The other two ravaged her body at an animalistic pace, they humped and thrusted as fast as they could without consideration for the mare’s pain or pleasure. They wanted to breed her and that was that.

He hadn’t even finished his morning coffee and he was already having an erection.

He found it hot, in a way. It made him jealous that she was getting bred like that by somepony else, if it were his choice, he’d be the one pinning her down right now. But by the stars, her sister gets so much prettier when her face is sucking on some cock. Blaze sat on the spot, hypnotized by the show that Lead gave him, idly stroking himself.

The force at which the dogs used her body made Lead to dig her hooves deep on the permafrost to keep her ground, her left hind leg shook in pain barely being able to hold the mare in position. The dog on her back humped for dear life, his cock poked and rasped on her insides with an intensity that only a wild animal could muster. The knot was a hard fit, only because of the hunger that the dog felt that he was able to muster the strength to pump into her; that fleshy ball spread the entrance of her pussy and pop out, making the loudest squishing sounds.

It felt as good as it hurt. Blaze was right, she was impatient, but this wasn’t why it drove her to do this… besides the sex. He was watching her. Her brother didn’t give her privacy when she presented herself to their dogs, his hungry stare never wavered, his big piece of meat hung just where she could see… and he was impatient too. He wanted to be in her. She could see such an envy in his eyes, he wanted to rip the dogs away and have his way with her like an animal.

Doing this in front of him showed her how much he wanted her as a mare. How he’d have his way with her, too.

She squealed around the cock in her mouth and sprayed cum all over the ground. The dogs didn’t stop, though.

Lead lost herself amidst her climax, it was only when the feeling of hot spunk filling the back of her mouth that brought her back. The nasty surprise made her cough and gag, she had to push the dog away so that she could cough out a bit of the semen so that she could breathe.

Not long after, the other dog behind her tensed - locking his cock on her pussy and shooting his seed into her womb as well, warming her up inside for the second time that day. If she wasn’t coughing up a storm, she’d bite her lip.

Snrk “Hey, Lead.” Blaze called out to her, chuckling to himself and holding his erection.

The hazy mare vacantly looked at him, but couldn’t muster any words amidst her hacking.

“You look like a bitch in heat.”

Lead glared at him, unamused. The dog that seeded her plopped himself out of her and moved away, with nothing else supporting her. Lead fell to the snow.

Cough. “Good to see that you’re having fun seeing your sister in distress, brother,” she coughed and spat. It tasted like wet ass.

She didn’t take Blaze’s amusement seriously, everything between them was all in good fun. Still, she was feeling a bit sore in the backside, these wilder rides usually left her feeling a bit of a sting until enough time had passed for her to recover. Lead continued to glare playfully at Blaze, when he stood up and slowly walked up in her direction; she didn’t pay attention to his starved gaze that bore on her, she only had eyes for the prize that swung in between his legs.

Before Lead realized, Blaze already had her under his torso and his erection right on her face - the same unwashed dick that came inside of her twice just last night. It drove her mad, it reawakened the fire on her pussy. And it wanted her.

“You’re my bitch, sis. Suck my cock, you slut.”

She didn’t even give the good courtesy of nodding before her tongue came out and enveloped his head. In Lead’s head, this was bliss.

Her tongue was overwhelmed by flavor, one stronger than the other. She could taste the salty dried cum that stuck to him instead of filling her womb, she could taste the leak that he took after he stuffed her with his batter, but the strongest of them all was the taste of herself - that female musk that hung on him, marked him and that drove him crazy when he took a whiff while she presented herself to him, like a bitch in heat. She didn’t gag, she didn’t retch, this was her addiction.

She didn’t even notice the fourth dog reaching her from behind until he was already pressing himself on her cum-soaked hole. He gripped his wooden claws on her and went in - her hole was already lubed up, his knot had already slid in. The luminescent rocket shone on her vulva, it popped in and out at breakneck speed - this one was in a hurry to give her a pup. She couldn’t take it anymore, her hind leg fell and all that kept her in place were her brother’s grip and her remaining straight leg.

Blaze couldn’t hold himself back any longer. He sat down in front of Lead, gazed at her lecherous smile while her face was frazzled in cum, and pushed her head downwards. She coughed once when she hit his medial ring, but she could keep it further. He held tightly to her mane and kept bobbing her head on his unwashed horsecock, and she took it all. She wanted to, after all, she taunted him because she wanted him to use her exactly like that.

Her eyes had already lost focus. Her brother was filling her throat and one of her pets was rasping her folds. All that she could taste, feel, she no longer cared as long as they kept going for more. Seeing the whore-ish glaze on his sister’s eyes, Blaze snapped. He got onto his hind hoofs and fucked her face as he did her pussy. Her lips remained tight around his dick, her tongue was loosely circling around it, what consciousness that was left of her worked only to satisfy his lust.

The more she felt Blaze abusing her face, the more her lower half tightened, she spasmed with utmost glee and wrung out the rocket that dug into her. Soon enough the animal couldn’t hold any longer and thrusted only the ball of his knot in her, the rest of her muscles were squeezing him, suffocating him until he gave her his seed.

He gave in, she milked him. He shot more and more until his balls ached, his cum mixed with his brother’s overflowed from her, coating her backside white. She painted the snow yellow.

Blaze would soon join them, the slowly expanding flare made it difficult to penetrate her face, but all it meant was that he needed to push it with more force. On Lead’s throat it was visible the shape of a thick member going in and out of her, with a flatter and bigger point at the end, almost cutting her intake of air. When it reached its maximum point, it stopped, shutting her off of oxygen, shooting load after load of his spunk deep in her.

He slowly went back, removing his ever hard member from her. When he reached her mouth, however, she held him in place as he still had stray spurts gushing from him. She took it all in, licking the head in every nook and cranny, gulping down all of his seed. She wouldn’t let any of him go to waste - ever.

She kept nursing him even when he didn’t have any more to offer, even when the dog unmounted her and oozed their pride on the ground. Even when he shrank halfway, she kissed him intimately. She had to make sure.

Only when her mouth started to feel sore is when she let go. She was almost breathless, but she looked as content as a pony can be. She tiredly looked at Blaze, and smiled.

“Love you,” she said.

He kissed her on the forehead.

“Love you too,” he answered.

He coddled her into his hooves and rested with her. She would take a while before she recovered from their playtime.

A strong gust of wind picked up around Lead’s cart, loudly whooshing past her ears and chilling her body. She and Blaze are a tad late to their delivery since they spent most of their mornings - and nights - catching up, so Lead decided to speed up a bit to salvage what time she could. In reality, they wouldn’t get much flack, if any, if they took a little while longer to arrive at Little Grove; especially considering that they’re the only ones who would even consider to deliver their letters and supplies to places in the middle of nowhere.

But the twins took pride in their work, and they wouldn’t let themselves trail behind for too long because of a few horny impulses. Or at least Lead did. Once she asked her brother how long until they’d arrive in the village, she lost her mind. She haphazardly tied their tent back into the sled, forgetting to wear their outdoors gear in the process, rushed their dogs in line and took off, kicking up a snowstorm behind their trail - Blaze barely had any time to organize the things that she forgot before she sped off.

“God fucking dammit Blaze, where is that stupid rock of yours?” Lead asked in a hurry. “The dogs are going as fast as they can, we should’ve reached that fucker by now!”

“This isn’t a race, sis, slow down.” Blaze told her, gripping tightly onto the sled’s handle.

“If I slow down then we’ll be doubly late! We’re off by over a day, we can’t slack off now!”

“Lead, calm down, we’re not far off from Little Grove,” Blaze tried to reassure his sister. “You’re freaking out again, it’s not good for your health.”

“What do you mean, I’m fine!” she yelled. “I am in total control, I’m not freaking out!”

“You’re yelling again.”

“No I’m not! The wind is getting louder, I have to speak up!”

“Sis, please stop.”

“I’m not going to be late for this delivery, Blaze.” she growled, her eyebrows furrowed in a grimace.

“Lead, the last time you went off like this you fell from the sled. I had to carry you all the way back to the hospital,” Blaze firmly held Lead’s shaky hoof. “Calm down. I don’t want you to get hurt again.”

“You-”

She wanted to argue, to tell him that he was making stuff up, but the arching in her hind leg didn’t lie. Whatever argument that she had prepared tangled up and died on her throat before she could even mutter them.

She botched up last time; lost control, almost lost her leg too. Having to spend a good while cooped up in a hospital room without much to do, her saving grace was that Blaze was there to keep her mind off the deadly boredom. But what stung the most was that he had to leave all of their load where she fell off to carry her safely - some of it had been damaged due to exposure.

“I…”

It took her months to take the oppressing cast off of her, and all that she could do was sit and wait. Blaze did small deliveries to nearby villages, but he always came back as soon as he could. And during all that time, she couldn’t do her job.

“Being late a day or a few is still better than being late for months, Lead.” Blaze reassured her.

He made sense, as usual. Lead barked at her dogs, telling them to slow down. The strong wind crawled to a steady breeze, diminishing the chill that pierced her and Blaze. Her crestfallen eyes refused to look at her brother’s, ashamed of what she did. She pounded on her sled, taking out her frustrations on the inanimate object while teardrops collected around her eyes.

“Fucking bullshit. This work is all that I do, Blaze, it’s all that I have. And here I am, fucking it all up. Can’t even do the deliveries on time. Can’t get a coltfriend, can’t ride the goddamn sled without breaking a leg, the fuck’s wrong with me.”

Blaze reached out and hugged his sister, leisurely caressing her back.

“Hey, You didn’t fuck up alone. I helped out with that, so don’t hog all the credit.” Blaze chimed in, earning a snort from Lead. “You and I, we’re doing a great job, Lead. Nopony else even bothers going through these remote areas, if it weren’t for us these ponies would probably take thrice the time or longer to get their goods delivered to them.”

“I should be on time…”

“We aren’t machines, sis. There’s no emergency right now, so taking a short break or two won’t kill anypony. I love this job as much as you, but we need breaks every so often, too.”

Lead grumbled under her breath. She knew that he was right, but she couldn’t quite easily bring herself to accept what she perceived to be her shortcoming.

“I don’t know how to help out in the coltfriend part, though. I’m not gay.”

She shoved her brother to the side. After a moment of reflection she gave off a long sigh, then cozied herself up on Blaze’s side.

“Can’t believe I spent so much time dicking around. Estrus might be hitting soon or something.” she begrudgingly grumbled.

“Hey, I did all of the dicking, give me some credit.”

She shoved him again.

“You dick.” She feigned anger, but the smirk that broke out betrayed her deception.

“Pretty sure you were enjoying it last time I stuck it in you.” he said, smiling back at her.

“Shut up!”

The twins chuckled as Lead tried to push Blaze away, only for him to hug tightly to her side and tickle her. There wasn’t much room for her to maneuver around his devilish tactics and she didn’t actually want to throw him off the sled, so she didn’t last long before she called uncle. Blaze clinged to her as his prize, and while she would occasionally playfully shove him, she relented to his teasing.

Miles of nondescript mounds of snow whizzed by them, Blaze continued to bug and entertain his sister to try and keep her mind off of her anxious thoughts. It was enough to mellow her out, the mare was no longer screaming at the top of her lungs and threatening to pull a maneuver that would make them sail across the sky like a raging santa, but he knew that her insecurities still made her uneasy.

Case and point, her hooves were trembling and she refused to set her sights on what was in front of them. Blaze clutched them, sharing his warmth with her.

“Hey now, chill. If anypony complains, which I’m sure nopony will, I’ll make up some story about me getting lost looking for a yeti.”

“I’m not shaking because of that, silly. I’m just cold.” she shot back with wavering confidence, shaking her entire body like if a ghost passed through her. “Brrrr!”

“Really now? Then I need to heat you up, get you to stop shaking.” Blaze taunted, embracing Lead tightly from the side, dragging her to the middle of the sled.

“Hey, stop it!” she giggled. “I’m good, it’ll go away soon!”

“I’m afraid I can’t let go, who’s going to guide the dogs if you freeze over? We’ll be stranded here forever!” Blaze jested.

“I already got enough heating from you this morning, you big teddy bear.” Lead squirmed on her brother’s hold, who was tough to get away from. “Got me fueled to last the rest of the day, so leggo!”

The comment made Blaze pause. Earlier that day she had woken him up with his dick deep into her folds, treated his morning wood until he released a big shot in her, it was right before her freakout.

“You mean… It’s still in there? You can feel it?”

“Y-Yeah. Your baby batter is sloshing riiiiight in here, on my womb.” Lead rubbed the fur below her belly and gave a teasing smile at her brother while blushing. “You filled me full, stud.”

Blaze couldn’t take his eyes off of her hoof. He always thought that it all eventually leaked out, and not that she hoarded it. Even though he came inside of her hours ago, the fact that she still had his semen swooshing in her, that she walked around places still with traces of him dominating her caused heat to surge within him. It didn’t take long for Lead to feel something hot and hard prodding at her flank.

“That got you hard?” Lead grasped his growing erection and rubbed it. “I went to town like this before, y’know. Had you leaking all over the snow, nopony even noticed.”

She succeeded in hardening him to his maximum girth with her dirty talk, his horsecock now hard as diamonds was nestled snugly on her belly and chest, lewdly warming her up. He saw a peculiar stone whizzing by in the corner of his eye, but didn’t call any attention to it. Instead, he threw himself over Lead and started to nibble her neck.

“Ah~ W-Wait, Bla-ah~ Blaze! We can’t fuck he-eeee~re in the sled!” Lead protested, her voice turning up pitches in reaction to his love bites.

“I can’t see why not, you blew me plenty in here before.” he stated nonchalantly while heaving heavily on her neck.

“Sticking it-it up in me is a bit different!”

Despite her complaints, Blaze didn’t cease his attack. A blowjob sounds like a nice way to calm him down, but she triggered his instincts and he won’t have any of it until he’s satisfied. He doubled down on his charge and got up to her face, blew on her ear and whispered to her:

“I want to cum inside of you and see my jizz coming out of your cunt when we stop in town.”

It had been more than a few years that Blaze managed to get her blushing so hard that her face changed colors, but Blaze pleasantly took her by surprise. As soon as those words were registered in her brain she lost the urge to struggle and her legs felt a little looser.

“Stand up,” He ordered her, giving her the space to move. “I’m gonna fill you up again.”

Lead complied immediately, stood on all fours and held onto the rail of the sled with her forehoofs for support. She lifted her rear high up for him and threw her tail to the side, exposing her dripping entrance. Blaze was upon her and the heat of his cock was already touching her lips, sliding them apart slightly. She waited for the familiar sensation of him stuffing her and reaching her cervix… only for it not to come.

“Blaze…?”

“I already came in this one. Time to do the other.”

A high-pitch squeal abruptly escaped her throat and shock spread across her face when she felt the slick touch of a tongue prodding her ponut. It circled around it once and then plunged its way inside, stretching her lax muscles and coating them with his thick saliva.

“Blaaa-aaa-aaa-aaazee~” she yelled his name with gritted teeth.

Lead’s backside tensed completely and her hooves gripped the rail with enough intensity to bend the metal. But Blaze did not falter, his adventurous tongue continued to explore her nethers and tenderly massage every inch that he could reach. His mind was devoid of any real thoughts besides the deep desire to breed his sister’s holes, while Lead’s head was overloaded with panic.

“Blaa~aa~aaze- you fuck!”

Despite her hollering, Blazing knew that her hysterics were a thinly-veiled mask of discontent. While he munched on her sensitive donut a little red button winked like mad, as if demanding attention. Blaze tended to it too, grasping it with a hoof while the other held his sister in place just in case she lost her footing again.

Which she almost did. Whatever words that her throat tried to process garbled up and came out as a mix of squealing and moaning, her mare juices trinkled out mixed with streaks of her morning prize. Lead had always been quick to get heated under the collar to hide what she really felt out of embarrassment, but if anything that just made Blaze want to fluster her more.

He lapped against her tight muscles, constantly licking and circling the soft tissue while his lips kissed her ponut. Once she was readily lubricated, he retracted his mouth and stood on his own, lining up their hips. Brief confusion gripped Lead when the delightful appendage stopped eating out her asshole, but it was soon replaced with a hopeful gasp once something bigger and thicker barged at her backdoor.

His flare rubbed against her back lips to gather some of its moisture and lined up against her ponut. The slightly gaping hole didn’t offer much resistance against the foreign object and it went in, although her tense walls halted his pace down to a crawl. Slowly and steady he carved his way through her ass, spreading her insides with a warmth that made her forget that she was buck naked amidst snow.

“Aaa- Aaaaaaaaaah~” she shouted loud enough that she’s sure even her dogs heard her.

Blaze pushed his hips forward, pushing more of his cock in her. Her ass was tight - way tighter than her vagina, although sometimes unbearably so. He pushed back then slapped back in, loosening her up to make space for more of his monstrous cock. Blaze slowly fucked Lead in the ass while they rode down their unmkared road, with his sister groaning in pleasure as she felt him split her in two.

“You make cute sounds, Lead. Cry more for me,” he whispered in her ear.

“Shu~uuuu~t up! You Di~aaah~Diiick!”

Both their hooves dug and scraped against the wooden scaffolding while their bodies tightly embraced each other, the rumbling of the snow under them vibrating their vehicle only added to the thrill. As cozy her sister’s ass was, Blaze wanted to dig in deeper; but his medial ring was having a hard time getting past her entrance. So he pounded harder and harder, almost throwing Lead out of the cart to no success.

“Aaah~- Aaah~- Aaaah~- Aaaah~- Fuuuuu~- uuu~- ck~” Lead hiccuped between each thrust.

Blaze would have none of it - he was going to coat all of her insides with his jizz and he was going to go as deep as possible. Her hole was tight, but greedy. It would only take a small incentive for it to open up further and receive his pulsating gift in her depths, and he knew exactly how to seduce it. He pressed his ring against her ponut, both kissing with high intensity, and whispered on Lead’s ear:

“We’ve already gone past the last mark some time ago. We’re very close to Little Grove right now.”

“Wha-”

He bit her ear. She processed his words. His ring pushed past and slid in.

“Mmmmmmmmmmmmffff~” Lead yelled through her hoofs covering her mouth.

Her clit shot out and a glistening stream flowed from her lips, her walls tensed and clenched around the cock ramming her ass. Drool dripped through the gaps of her hoof, panic and ecstasy held hands - she wanted to scream at him to stop but all that she could think was that he should keep going even after they rode through the middle of town.

“Fuck, you feel so good, sis. How’d you like fucking in the open?” Blaze taunted her.

“Mmmmmmf~~~ Mmm~~Mmmmm~” she screamed.

“We might reach them anytime soon, what if somepony catches us loving each other like if it were estrus season?”

“Mmmmmmmmmmmmmmmmmmmmmmfff! Aaaah~” her muffled voice came out when Blaze pushed her hoofs away from her mouth.

“I want to hear your cute noises. Moan more for me, Lead.”

And she did, her painful moans echoed across the snowscape louder than the call of a horn, drowning out the loud smacking coming from her back. Blaze’s hips pumped Lead’s asshole with his horsecock at a rate that tried to copy the sled’s speed, loosening the hungry hole as he hilted the entire thing in her. His fuzzy balls slapped on her pussy lips at each thrust, her left foreleg shook as it barely handled carrying the rest of her pleasure-drowned body.

“Blaze~ Blaze~ Blaze~ Blaze~ Blaaaaaaze~”

Suddenly it became harder for Blaze to ravage her ass - his flare was slowly expanding and spreading her intestines. Every thrust was harder to push through, she pushed against his head and he felt like he could burst at every inch that was between him and her deepest part.

He tackled her one last time, exploding in her as he bit down on her ear.

“aaaaaaaaaAAAAAAAAAAAAA!”

Jets of his hot spunk burst in her, burning her as it coursed through her folds. There was so much of it, more than enough to fill her womb thrice over - there was simply too much, it bulged her belly. And it wouldn’t stop coming either, when a spurt died down another came to replace the last one, again and again and again and again until there was nothing left in his balls to shoot for the rest of the day.

Lead’s eyes refused to move from the top of her skull, her lungs worked overtime to refill her body with precious oxygen - her chest puffed in and out as she huffed tiredly mixed with loud moans. Her legs felt like jello, her head was lighter than air, she fell down on the wood to save energy.

Blaze wasn’t any worse for wear, his hips and balls ached while his dick was in the clutches of a vice grip that refused to let the tip let go. After much struggle - and a very wet plop, the cum-coated flare was set free; his sister’s ponut gaped very wide, presenting to the world the kind of monster that ravaged it and spurted the spoils that it stole from.

Lead felt tired - she had spent most of these days bonding with Blaze to get a proper rest, and it was catching up to her. It was only an excruciatingly long time catching her breath that she realized that the snow wasn’t moving, and that she was resting on her brother’s chest.

“Wha… why’d we stop…?” she asked between short heaves.

“Dogs heard you, they must’ve thought you had fallen again.” Blaze answered while he caressed her head.

Just as he spoke, the dogs looked at her with deep worry settled in their eyes. Lead gave a weak laugh, she was right in thinking that they were the most loyal pets she could have chosen.

The thrill of getting her ass blown by Blaze was now over, and the reality of it all settled on her. Thankfully, it seems like they stopped far away from the settlement, there were no buildings in sight - not even in the distant horizon. She faintly smacked her brother in the face and leaned her face on his chest tuft.

“Dick,” she muttered.

“Pussy,” he retorted.

“Yeah, I got one of those.”

“Best one I’ve ever had.”

“The only one you’ve ever had.” Lead smacked him again.

“Are you sure about that?” Blaze asked with a serious face.

Lead raised an eyebrow at him.

“Wait, did you really…?”

“Nah. Messing with you.” Blaze smirked at her naivete.

Lead smacked her brother in the belly, making him grunt and clutch his abused tummy.

“Fucking dick, don’t make me jealous like that.” she muttered, then sighed. “Be real, do you really think I have any chance at getting a coltfriend? I’m honestly scared.”

“Urk- Yeah. Yeah, you got it.” Blaze grunted. “Just keep your head on straight and you’ll be fine. You’re lovely when you’re not punching your brother.”

She smacked him once more for good measure.

“Yeah, both of us know that I’m no good at that without you around.” Lead muttered.

There was a brief silence between them while Blaze recovered from the repeated gut punches. Lead tried to work her words carefully while a reddish tint appeared around her cheeks.

“Hey… Blaze?”

“Yeah?” he grunted.

“You… The plan is still up, right? You’ll share your marefriend if you get one, right?”

“Wouldn’t do otherwise, Lead. You too, right?”

“Can’t make do without you, Blaze. Hey?”

“Love you, brother.” Lead laughed, smirking devilishly.

“...Love you too, sis.”
