Then Don't Jump into the Fire

All Characters are presumed to be 18+ in this story.

It was never this bad. Twilight Sparkle had experienced some really bad heats before, and she was no stranger to the discomfort, but this was a whole different level of lust. This heat permeated the poor mare’s entire body, radiating upwards from her loins with intense, sexually-fueled waves. The area between her thighs was a burning sun that could not be quenched regardless of how much marecum and arousal flooded the area.

Her entire bedroom felt as humid as a swamp, and stank of sweat and sex. The sheets on the bed were soaked through with a collective blend of perspiration, marecum, and even a little bit of urine from when Twilight really lost control.

Rainbow Dash rolled off of her spot on top of Twilight, riding down from the high of her last orgasm. “Holy shit, Twi,” the pegasus panted as she tried to catch her breath. “Please tell me that at least somewhat worked for you.”

The alicorn just lay there, breathing heavily. “Yeah… a little…” she managed to breathe out. In truth, she was just a horny as she was before the three powerful orgams her pegasus friend brought upon her.

“A little!?” Rainbow cried out in indignation. “Are you serious? It can’t be that fucking bad!”

Twilight just moaned in response, using her magic to open the window and let some fresher (and hopefully cooler) air into the room. “I don’t know, Dash. This season is just horrible. I have no idea what brought it on!”

Rainbow looked at her friend sympathetically. “Maybe you should take a vacation,” she suggested. “I dunno, go somewhere cooler or whatever. With cheap prostitutes.”

Twilight rolled her eyes. “I am a Princess of Equestria, Rainbow Dash. I am not hiring cheap prostitutes.” She paused for a moment. “Wait, I’m not going to hire any prostitutes!”

The pegasus laughed. “Well, at least go somewhere cooler,” she said. “You’ll feel better if you’re not hot and sweaty all the time.” She ran a cyan hoof along Twilight’s damp coat. “Even if I do love you like this…”

The teasing and flirting did nothing to lower Twilight’s horniness. “Daaaash,” she moaned, latching onto the hoof and dragging it lower.

“Jeez, Twi,” chuckled Rainbow as she started to hoof the alicorn’s dripping snatch. “I’m going to start to get worried about myself! This is going to be like the fifth time today!”

“You don’t need to get off again,” Twilight moaned. “Just fuck me!”

It was Rainbow’s turn to roll her eyes. “Wow, thanks, Twi. Glad you care about my pleasure, too,” she said sarcastically as she leaned down and began to lap at the drooling pony pussy between Twilight’s legs.

After another ten orgasms, and Rainbow finally tapping out, Twilight was once again left alone and hot and bothered. Masturbating barely worked to get her off, her dildos (all six sizes, and even the dragon king one) did little to help, and she was running out of ponies to fuck in Ponyville.

She briefly began to consider Rainbow’s idea of going to Las Pegasus and hiring a myriad of cheap prostitutes, but she forced herself to push that idea from her mind. The alicorn was still mostly against the idea of going on a very public vacation and then renting out a bunch of cheap whorses to satiate her lust. It was very unprofessional.

Then, an idea hit her. As far as she knew, humans did not go into heat. Twilight remembered asking Sunset about it a while ago, and the teenager had replied that they didn’t go into heat as far as she knew, and she had been living there for years. Sunset did mention something else at the time, but Twilight couldn’t remember the specifics, and it wasn’t heat, so she really didn’t care right now.

“SPIKE!” she screamed as she threw some books and other essentials into a saddlebag. “I’M GOING AWAY FOR A WEEK!” There was no response, but again, Twilight couldn’t care less. The only thing on her mind was making the damn burning in her loins go away, and she would do everything short of kill a pony to get that done.

Within minutes, Twilight was standing in front of the portal to the human world, ready to go through. She took a deep breath, fanned herself with her tail for a few seconds, and then she stepped through.

The nauseating swirl of colors dominated her perception for the interdimensional journey before spitting her out right in front of Canterlot High. Twilight wobbled on her long, bipedal legs for a few moments, trying to catch her balance as the human world shifted into view around her.

“I’ll never get used to that…” she mumbled, swallowing down her lunch and probably some of Rainbow’s pussy juice before it made a reappearance.

“Twilight?” a voice called out, and Twilight turned to see Sunset Shimmer sitting up against the statue next to her.

Twilight smiled sheepishly and waved. “Oh, hi, Sunset,” she said. “Sorry for not giving you a heads up. I just wanted to come and say hi. And maybe cool down a bit.”

Sunset gave her a sympathetic smile. “Oh, it’s a bad one, huh?”

Twilight nodded as her face flushed red. “Hopefully being here helps.” The look she got in response made her question her theory. “I mean… humans don’t go into heat, right? That’s what you said.”

“No, they don’t,” Sunset reassured. “But you came over already in heat. Your body is already in that state, and I don’t know if the portal will know how to compensate for that.”

Damn. Twilight didn’t even think of that. “Fuck!” she screamed, drawing the attention of a few students passing by. She flushed even deeper red as she gave an apologetic wave. “So this is just going to be worse, because I won’t be able to get myself off.”

Sunset’s face was growing crimson now as well. “Well, I mean we don’t know that yet - the heat thing. I mean, how are you feeling right now?”

Twilight paused, and contemplated on it for a minute. “I don’t feel hot and bothered,” she finally said. “I’m still really horny though, but that could be residual.”

“Okay, so maybe it is working,” Sunset said, closing her book. “Let’s just wait and see. And if it turns out that you are still in heat, we can work something out, maybe.” The teenager looked off to the side with a blush. “I have a few ideas…”

Twilight rushed forward and wrapped her friend in a big hug. “Oh, thank you, Sunset,” she said earnestly. “I could kiss you right now!”

Sunset laughed awkwardly. “Heh heh, well… let’s see if we can get you into some air conditioning. It is pretty hot outside today, and you’re probably sick of the warmth.”

“Oh, definitely. That sounds amazing!” Twilight let out a sigh as Sunset began to pack up her things. She already felt bad for showing up unannounced and really didn’t want to impose any more, but the offer of a cool space was just too tempting. She also tried to push Sunsets secondary offer to the back of her mind - she didn’t really want to think about sex any more than she had to.

Twilight had made the trip to Sunset’s small apartment many times before on plenty of her previous trips. It never took too long to get there, but today, in the grueling sun, it felt like a journey of a thousand miles. She didn’t want to get too pessimistic, but the heat wasn’t really doing anything to soothe her burning loins.

Entering the apartment offered little respite. “Oh shit, I forgot to leave the AC on,” Sunset cursed as she rushed over to the unit underneath the window. “Fuck, Twi. I’m so sorry!”

“It’s… it’s really no problem,” Twilight said, an uncomfortable smile on her face as she wiped some sweat from her brow. “I’m sure it’ll be cooler in no time.” Sunset offered her a hopeful smile in return, and Twilight felt a little bit better. She was grateful that she at least had another pony who understood what she was going through.

Sunset went into her bedroom and started rifling around in her closet. “Here, Twilight. I got some lighter clothes that should help cool you down.” Twilight followed her into the room as she tossed a thin sundress onto the bed. “Feel free to put it on.”

“Thanks so much,” Twilight said as she immediately began to shed her layers. Just taking off her top made her feel so much better, as the cooling air from the air conditioner blew against her skin.

“You know,” Sunset began, looking off to the side. “You could also just lounge around here naked. I… I really don’t mind.” A small blush creeped across her face as she twirled a strand of her red and golden hair.

Under normal circumstances, Twilight wouldn’t even consider the offer. As a matter of fact, given her current state, she probably shouldn’t have even been considering it now. But standing here, half naked in the middle of Sunset’s bedroom, with the cool air blowing against her bare skin, Twilight caved. Besides, they were both ponies, and ponies didn’t normally wear clothes anyways.

“T-that would actually probably help,” she said timidly. “If you’re comfortable, of course.”

Sunset smiled and shook her head. “Of course, I wouldn’t have offered it if I wasn’t.”

Twilight let her skirt and leggings slide down, adding to the pile of crumpled fabric on the floor. “Thanks, Sunset.”

“No problem, Twi,” the teenager replied. “Actually, and this is speaking from experience, you should probably shed the underwear, too.”

Now it was Twilight’s turn to blush. “A-are you sure. I know with humans that’s a little… and I don’t have my tail to cover it up…”

Sunset cut her off. “Twi… Twilight… It's fine. It’ll make you feel better.”

Twilight looked at Sunset uncertainly for a few moments before reaching back behind her and unclasping her bra. She was a little embarrassed as the fabric took a bit of effort to peel away from her damp, sweat-soaked skin. The cool air brushed against her bare nipples, hardening them a little bit, but she couldn’t deny how much of a relief it was.

Next, she reached down and gripped the waistband of her panties. Looking back at Sunset for confirmation and receiving a quick nod, Twilight steeled herself and pulled them down. Her blush depended as she saw just how soaked the front of her crotch was with her own juices, and even the back string with her ass sweat. They, too, joined the pile on the floor as Twilight now stood completely nude in Sunset’s bedroom.

The two girls just stood there awkwardly for a moment, Sunset trying not to eye Twilight up, and Twilight trying to avoid eye contact with Sunset.

“I-I’m going to go make some lemonade,” Sunset finally said, pointing back towards the living room. She rushed out, leaving Twilight alone and naked in her bedroom.

Twilight watched her go, idly fanning herself with a hand. She was completely drenched between her legs, dribbles of her own feminine juices trickling down the sides of her thighs. With a quiet moan, she started fanning herself down there, too. She was so hot and tired, and just wanted this to be over already. Not even thinking about it, she went over and sat down on the side of Sunset’s bed.

Immediately, she blushed as she heard a damp squelch as her arousal soaked into Sunset’s bedsheets. Twilight quickly stood up and looked at the very obvious wet stain in the tidy purple fabric. “Shit shit shit,” she hissed out, not knowing what to do. She fiddled with the covers, to try and block it from view, but it would probably stain the sheets anyways.

However, during her panic, another feeling came over her. Seeing her mark on Sunset’s sheets felt so… naughty. The sight was actually beginning to arouse her even more. She lost her focus on why she was here for a moment, and her hand immediately dipped down between her legs.

The sensation was so much different from hoofing herself! Her noble digits glided across her swollen pussy lips, sending sparks of pleasure from her touches. She gently collapsed backwards onto Sunset’s bed, and slipped one, then two, then three of her fingers inside of her dripping wet snatch.

Twilight was now openly masturbating on her friend’s bed, without a single care in the world. Her mind was completely consumed by the burning heat in her crotch, and her only desire was to satiate that need however possible. She lay back on the bed, furiously finger-fucking herself. Her hand reached up to grope at her breasts, and she let out a low moan of pleasure as she molested herself in her friend’s bedroom.

“Oh my god, I’m so sorry!” a voice suddenly exclaimed, ripping Twilight out of her fantasy. She stopped touching herself, her eyes darting to a shocked-looking Sunset Shimmer, and shame immediately replaced most of her lust. She quickly sat up and did her best to cover both herself and the growing wet spot on Sunset’s bed.

“I’m sorry- I didn’t mean- It just sorta happened…” Twilight stammered out excuses through her furious blushing, hiding her face with her hands. She could smell herself on her fingers, which really wasn’t helping her situation at all.

“No, Twilight, listen,” Sunset began, placing her hands on Twilight’s shoulders, making the girl start at the sudden touch. “It’s fine, I understand, really.”

Sunset’s words did little to help Twilight’s embarrassment, but they did help her calm down a bit. “I just… I don’t know what came over me,” she whispered. “I’ve never been this out of control, I swear!”

The taller girl pulled her into an unexpectedly tight hug. “Twilight, calm down. It’s fine,” she said. Both girls tried to ignore their bodies pressing together, but it was especially hard. “Let’s… let’s get you that relief you wanted, okay?”

Not knowing what else to do, or how else to quench her ever-growing need for sex, Twilight nodded and followed along with Sunset.

“Put on that dress I laid out, yeah?” Sunset said, stepping away from the other girl. “Then we’ll head out. Don’t worry about the underwear, you certainly won’t need it.”

Twilight did as she was told, pulling the sundress over her head. “W-where are we going?” she asked, following Sunset out into the living room.

“You’ll see,” was the only cryptic response.

“Applejack’s farm?” Twilight asked as she stepped off the back of the motorcycle. She tried to ignore the obvious wet streak on the leather seat as best as she could, and hoped that Sunset didn’t notice it either.

Sunset did in fact notice it, but decided against teasing Twilight any further. Instead, she just nodded in reply. “Where else?” she replied with a sly grin, and waved for Twilight to follow her.

Twilight did walk after her, although apprehensively. “Well, uh… I thought you were taking me somewhere to… you know…” she trailed off, a deep blush flushing across her cheeks.

A sly smile crossed Sunset’s face. “Yeah. I am,” she confirmed, grabbing Twilight’s wrist and pulling her towards the stables.

The closer they got, the more Twilight actually realized what was about to happen. It dawned across her in phases, and by the time they were standing in front of the large barn door, she had figured out why Sunset had brought her here.

“S-sunset!” she said worriedly, pulling the other girl back from opening the door. “W-what?! We can’t… we can’t do this!”

But Sunset just gave her a reassuring smile. “Yes, we can, actually,” she replied. “AJ is totally fine with it.” Her face fell slightly, before she added, “Of course, unless you’re not. Which is fine, we don’t have to…” she trailed off, disappointment clear on her face.

Twilight was not against the idea, quite the opposite actually. However, she had been here often enough to know that an activity like this was not totally acceptable in the human world. But… if Applejack was okay with it…

“N-no… I think…” Twilight stuttered, nearly overwhelmed by her nerves. “I w-want to do this.”

Sunset smiled at Twilight, squeezing her arm gently. “It’s okay Twi, I’ll be here the whole time.” With the added reassurance, Sunset opened the door to the barn, and the two girls stepped inside.

They walked down the center aisle, passing a few stalls before coming to a stop in front of one. There were a few huffs and neighs coming from behind it, signalling that it was in fact occupied. Sunset looked at Twilight one last time, silently asking if she was still willing to go through with it. The girl simply gave her a quick nod, and Sunset stepped forward. “This is Buck,” she introduced as she opened the door to the stall.

Twilight’s breath hitched as she saw him. The horse was much larger than she thought it would be - far larger than she ever remembered seeing one in this world. If she measured from the ground to the top of its head, it was even taller than she was. For some reason, the realization only made her pussy even more wet.

Sunset showed no apprehension as she walked right up to the majestic creature, rubbing her hand along its side and standing on her tiptoes to plant a kiss on its cheek. “Hey, Buck,” she said softly into his ear. The horse nickered in reply, and pressed into her. “I brought a friend,” Sunset continued, gesturing over to where Twilight was hovering near the door.

Twilight gave an awkward wave. “H-hey there… Mister Buck,” she said, cringing at her own words. Sunset laughed at her awkwardness and waved her over. Twilight stepped into the stall, and approached where the other two were standing.

“You’re gonna show her a good time, aren’t you, Buck?” Sunset said, her voice taking on a sultry tone. This time, Buck let out a whinny in reply and took a step towards Twilight.

For her part, Twilight did not know exactly how to feel about the approaching creature. Her dildos at home were larger than the average stallion to be sure - what mare’s weren’t? However, Buck was on a whole different scale. His size was quite intimidating, but a growing part of her was becoming more and more attracted to that fact.

Sunset patted the horse’s rear, and gestured to Twilight to come forward again. “Come on, he’s quite friendly,” she encouraged, and the girl finally did step forward.

Buck leaned forward, sniffing curiously at Twilight before pulling back and nickering excitedly. Sunset gave the beast a reassuring rub, and grabbed Twilight’s wrist, pulling it towards her and resting it against the soft hair of the horse’s skin.

Twilight just held her hand there for a moment, feeling the warmth and the steady flexing of Buck’s muscles. Then, timidly, she brushed along its side, feeling the surprisingly soft hair underneath her hand. She could feel power and strength underneath the skin - large unyielding muscles twitching at her touch. “Oh wow,” she breathed. Between her legs, her pussy quivered, begging for some attention.

And then the smell hit her.

A powerful, earthy musk flooded Twilight’s nose. It was so overwhelming at first, she almost didn’t recognize it. But soon, the scent was unmistakable to her - it was the potent musk of a stallion.

Twilight knelt down beside Buck, the straw floor digging into her bare knees, and she let out a tiny gasp at what she saw. Slowly but surely, a large, dangling horsecock was slipping out of its sheath and hanging beneath the beast. Its mostly flaccid length pointed towards the ground, flexing every so often.

“He can smell your heat,” Sunset said from somewhere above Twilight. “It’s making him horny.” She slipped a hand beneath the waistband of her red skirt. “It’s making me horny…”

And it was definitely making Twilight horny. She leaned into the horse’s crotch, breathing in the deep, musky stink of his dick. Almost unconsciously, her hands reached up to fondle him - one gripping onto the weighty shaft, and the other reaching up to cup his large balls. Twilight brought the penis closer to her face until the hot, leathery flesh was pressing right up against her nose, and took a deep breath.

As Twilight was increasingly consumed in her haze of musk-induced lust, Sunset knelt down next to her. She smiled as she watched her friend huff the essence of Buck’s horsecock, and slowly leaned in next to her.

Twilight barely noticed as Sunset’s face pressed against hers and leaned into the long, hard length as well. She was too absorbed in the potent scent of dirty horse dick. She only realized when the cock was gently taken from her grasp, and she was pushed to the side. The girl then watched in awe as Sunset opened her mouth wide, and took Buck’s penis down her throat.

Sunset Shimmer had certainly had plenty of practice sucking horsecock. And this was definitely not the first since she was sucking Buck’s. She slurped the precum right out of his leaking head while pumping the massive shaft with both of her hands.

The other girl watched in awe as Sunset’s lips pushed up to just barely wrap around his medial ring before pulling back and suckling at the head of his dick. Twilight couldn’t even begin to fathom how the teenager was guzzling the large cock down her throat with such skill and ease - Twilight had trouble deep-throating the normal sized horsecocks back in Equestria.

With a gasp, Sunset pulled her head back off of the large penis, gulping in some deep breaths. Her mouth was smeared with a combination of her own spit and Buck’s precum, creating a sticky halo around her lips. She noticed Twilight intensely watching her, and gave the girl a small smile. “You… you wanna’ give it a try?” she asked, still panting.

Twilight nodded absentmindedly. Of course she wanted to give it a try!

Sunset backed away from the hanging member, holding it towards Twilight as an invitation. Twilight got on her knees and shuffled forwards, and was soon sitting before the large cock.

“Go ahead,” Sunset whispered in encouragement. “He wants it.”

Without any more hesitation, Twilight reached out and firmly grasped the pulsing rod in front of her. She felt it in her hands for a few moments, feeling the strong, rhythmic twitching against her fingers. Then, she slowly began to slide her hands up and down the length, wanting to feel as much of it as she could. It felt like she was on fire, the combined heat of Buck’s cock and her own arousal combining to create an intense feeling of lust and anticipation. The only reason she was holding back now was because she wanted to experience everything the hot stallion had to offer.

Sunset knelt beside her, idly fondling Buck’s massive balls. The full, weighty orbs hung low behind his penis, and were practically pulsing along with his length, churning full with a deluge of fresh horsey spunk.

Finally, Twilight leaned forward. She took a deep sniff of the thick cock as she began to pump it up and down with both hands. The deep intense musk that had permeated the air around them was much, much stronger here. The odor sparked her lust, and she felt a gush of fluid flow down between her legs.

She leaned forward even further, flattening her nostrils against the leathery flesh of the penis in front of her, desperate to inhale more of the horse’s sexual scent. Then, unable to hold herself back any longer, she stuck out her tongue, and gave the cock a sensual lick.

The potent taste of the stallionhood immediately assaulted Twilight’s tongue. It was a powerful, heavy, and sweaty scent, and she went for a second lick without any hesitation. Then a third, and a fourth, and then she was practically slobbering on the cock, trying to lap up as much of its essence as possible.

Twilight worked her way down the shaft, and sensually suckled on the tip of Buck’s penis. The taste of his salty precum and Sunset’s warm saliva mingled in her mouth, creating a pleasant sauce of sex with his natural taste. For not the first time recently, she was lost in her own world of lust, and did not notice as Sunset dragged a large hay bale over.

“You ready, Twi?” Sunset asked, smirking as she saw the girl practically making out with the head of Buck’s penis. “I’ll take that as a yes.”

Twilight suddenly felt herself get lifted up, and then pushed backwards onto a hay bale. The next thing she knew, Buck’s large figure had stepped above her, and a firm, heavy weight was pressing against her crotch.

“Oh my gosh,” she gasped out. The thing was huge! It had to be at least two feet long! It twitched and throbbed against her hot, wet pussy, and Twilight couldn’t help but grind back up against it. Her pussy juices mixed with the rest of Sunset’s saliva, clinging to the lengthy shaft.

Suddenly, Twilight felt a hand on her thigh, gently pushing her legs even wider. Sunset had crawled underneath Buck’s hind legs, eager to help her friend lose her bestial virginity. She took the mighty shaft in her hand, and guided it towards the waiting, dripping snatch.

“OH FUCK!” screamed Twilight as Buck’s cock found her pussy and pushed right in. Her tunnel stretched out to accommodate the large mass as it slid deeper and deeper inside of her. It found its limit just past the medial ring, and Twilight’s eyes locked onto the large bulge poking up through her stomach. “Holy f-fuck it’s massive!”

Buck pulled back out slowly before pressing himself back into her, and Twilight practically went cross-eyed. She threw her head back and let out a long, low moan, her pussy clenching around the meaty cock. “Oooooh fuuuuuck!”

Sunset smiled, watching the length disappear and reappear from Twilight’s wet slit. Her hand idly fondled Buck’s swinging balls, occasionally lapping out to give the musky, sweaty flesh some passionate licks.

The horse’s thrusting gradually picked up pace, easing his fuckmate into a fast, yet steady rhythm. Twilight’s moans got louder and more frequent with each increase, until the point where she was practically just wailing out moans as Buck brutally fucked her.

The massive cock repeatedly slammed home into Twilight’s cunt, stretching her out more than she ever imagined she could be. The length and girth combined together, touching each and every one of Twilight’s pleasure points - something that up until now, she had not been able to achieve with any stallion or dildo back home. Her eyes rolled back into her head and her tongue lolled out of her mouth in a pleasured display of sexual overstimulation. A cacophony of drawn-out moans ripped out of her throat, each one indistinguishable from the last. Her mind was going haywire with pleasure, and she was barely able to hold on for another few seconds before she came.

Twilight’s entire body shivered as her first orgasm ripped through her. Her hands clutched at the straw beneath her, and her legs quaked in the air. A generous helping of girlcum drooled out of her used slit, leaking out around the large rod and pooling between her buttcheeks. All the while Buck barely slowed down his thrusting.

At this point, Sunset had crawled out from underneath the horse and had stepped up behind him, eager to try one of her favorite delicacies. She gently gripped the stallion’s tail and flipped it aside, baring the pert knob of puckered flesh that was his anus.

As she had come to expect with him, Buck’s white ass was stained and smeared with brown streaks. She leaned in, practically pressing her face up against the horse’s ass and breathed in. The musky scent of dirty stallion ass flooded into her nose, causing her to let out a low moan. The scent mixed with the bitter aroma of stale scat, creating a noxious perfume that the teenager had come to love and, at times, crave. This was exactly what she wanted.

Without any more delay, Sunset stuck out her tongue and dove in, running her tongue up, down and around the dirty pucker, lapping up the filthy grime that had collected there. Her tongue cleaned up all of the shit that was caked onto the outside of the wrinkled hole, before pressing firmly against its center and slipping into the depths of Buck’s ass.

The taste inside his rectum was even more potent, and Sunset moaned lustfully into the hole as she scraped scat off of the inside of his colon and brought it back into her mouth. The bitter and gritty clumps dissolved into a thick, earthy paste inside her maw, and she smeared it around the inside of her mouth, trying to extract as much of the flavor as possible before going back in for more.

Meanwhile, she could feel the powerful thrusts into her friend as she sloppily made out with the horse’s anus. Twilight’s entire body rocked underneath Buck’s rapid thrusts, losing herself into a state of hazy lust. She had barely come down from the high of her last orgam, but was quickly approaching a second one. The horse was relentless, holding back nothing as he ruthlessly fucked her silly.

“Oh goooooooooood!” Twilight screamed through a moan as another orgasm hit her. Her body shook with a combination of pleasure and overstimulation. Her mind practically went haywire as she writhed on top of the hay bale. Simultaneously, it was at that moment that Twilight lost any last semblance of her control. The immense pressure in her groin began to force things along that she would have normally been able to hold back.

A pale yellow stream of urine erupted out of her pussy, splashing against Buck’s thick cock and pouring down onto the barn floor below. Her butthole opened up to let out a quick burst of anal air before logs of shit began to push against her rim, crackling as they slid out. Her poop fell to the floor with dull, damp thuds, creating a small pile underneath her lovemaking. The soft feces smeared against her asshole and the inside of her cheeks, creating a bit of a mess on the way out, but Twilight literally could not care at all. Actually, the fact that she was shitting herself only registered in a small corner of her mind that was not completely consumed by her own orgasm. She simply lay there and took it, moaning all the while as the horse literally fucked the shit out of her.

And then, in the middle of it all, Buck slammed home. His massive horsecock plunged deep into Twilight’s gaping cunt, and the head of his thick rod flared out. The cock flexed inside of her pussy as it pumped her womb full of stallion seed, and Twilight cooed as the warm spunk filled her up.

The last of her shit slid out of her ass as she was loaded up with cum, falling to the floor and landing on top of her sizable pile of excrement with a dull splat. Buck chose that moment to step backwards, and pull out of Twilight’s stretched pussy. The movement forced a final fart out of her asshole, the tight hole quivering as his large cock slid out of her wet and gaping cunt.

Back backing up pulled Sunset out of her own world, and she pulled her face out of the horse's ass, allowing him to take a few steps back and away from the ruined girl. It was only then that she noticed the state that Twilight was in. “Oh, holy fuck, Twi,” Sunset said with a little laugh. “He fucking ruined you!” Twilight didn’t reply as Sunset knelt beside her, still trying to float her way back out of her powerful orgasm.

Sunset’s gaze drifted down to the floor, where she saw the fresh pile of shit that Twilight had pushed out. “Fucked the shit out of you, actually…” she mused to herself.

The girl leaned in between Twilight’s legs and gently began to lick at the mess that had been left behind. She slurped the creampie out of Twilight’s gaping pussy, the salty taste of horsecum, pee, and pussy juice gracing her tastebuds. Sunset let out a content sigh as she savored the flavor, mixing it with Twilight’s own fluids before swallowing. She went back in for seconds, dutifully slurping and licking until her pussy had been reasonably cleaned out. Then, she turned her attention to the lower hole.

Twilight let out a surprised coo as Sunset’s tongue circled around her anus. The fiery-haired girl cleaned her there as well, orally removing the smears from her accident and savoring the new and unique flavor of her friend’s crap. Then, just to be playful, she wriggled her tongue inside the pulsing pucker and swirled it around the inside of Twilight’s rectum, enjoying the pleasured moan it drew out of her.

She pulled her mouth away from her friend’s backside with a small pop, and watched in satisfaction as Twilight’s butthole clenched around the air that was left behind. The pile of shit beneath her caught Sunset’s eye, and a dirty thought crossed her mind. Feeling a bit bold, she decided to test the waters a little bit. Sunset made sure to catch Twilight’s eye, then leaned down and reached into the pile of crap.

Twilight’s eyes widened as Sunset lifted up her hand. She held up a large glob of Twilight’s fresh shit, smeared across her fingers and nestled in her curved palm. But Twilight didn’t even have time to be embarrassed as Sunset gave her a sultry wink, and then leaned forward and licked it.

A gasp escaped Twilight as she watched Sunset essentially eat her poop. She never imagined anyone ever doing that before, especially with her own. Well, she had heard of ponies who indulged in that particular fetish, but it wasn’t anything that ever really came up. Now, she was laying on top of a hay bale after being fucked by a horse, and was watching someone slobber over her poop right in front of her.

And she wanted to know what it was like.

A new wave of lust overtook her body, and Twilight desperately wanted to indulge in this new experience. Luckily, that seemed to be exactly what Sunset had in mind as she climbed up on top of Twilight, hovering over her. Their eyes locked, half-lidded gaze meeting half-lidded gaze. And then Sunset dipped down and caught her friend’s lips in a deep, passionate kiss.

A low moan growled out of Twilight’s throat as the taste of her own shit oozed into her mouth. She wasn’t entirely sure what she would feel, or how it would taste, but never in a million years did she expect to react like this. The naturally bitter flavor of her scat was sweetened by Sunset’s saliva, creating a strange, but not unpleasant flavor in her mouth. Their tongues danced together, and Twilight found herself lapping off more of her own filth, eager for an extra taste.

Sunset’s dirty hand reached down and groped Twilight’s breast through the thin fabric of her sundress, smearing the filth into the fabric. Twilight reached down and lifted the dress up as much as she could, giving the other girl access to her bare skin. She wanted to feel her wet shit smeared across her chest. She wanted to be as filthy as possible. And Sunset happily obliged.

She smeared Twilight’s scat across her exposed breast, sullying the clean skin. Twilight moaned as the warm muck was smeared on her, and she reached up with her own hand to help spread it out, then reached up and held one of Sunset’s hefty breasts and began smearing it on her.

They leaned into their kiss, passionately swapping spit and scat while they covered each other with smelly filth. Twilight groped Sunset’s tits with her hand, impressed and slightly jealous of the girl’s larger form. Not that she cared about human proportions, of course. But they were certainly fun to play with - and paint with her shit.

Their attention was pulled away from each other as Buck suddenly let out a loud whinney. They watched as his tail lifted to allow a boisterous fart to explode out of his rear. Then, his anus flexed and spread around a large, round turd.

The shit tumbled out of his ass, piling up onto the floor in a sloppy pile. Twilight watched in awe at the sheer amount of crap Buck produced, punctuating each new ball of shit with a dry, airy fart. Finally, a deluge of semi-solid poop exploded out of his puckered asshole, coating the entire pile in a muddy gravy-like slop.

Her chagrin and hesitancy long gone, Twilight knew exactly what she wanted Sunset to do with that mound of horseapples. Sunset seemed to have the same idea. She reached down and scooped up a large amount of the horse poop, before bringing it over and depositing it right on Twilight’s bare stomach.

The weight and warmth of the manure was immediately present, and Twilight moaned at the sensation. Sunset began to spread the muck out in a filthy massage, smearing the shit all over Twilight’s pale lavender skin. Her back arched and she adored Sunset’s touch, craving more and more of it as she continued to pile scat on top of her.

The disgusting scent of horse shit filled the stall, only increasing in potency as the round clumps of scat broke apart and smeared across skin. It was perhaps the most depraved thing Twilight had ever experienced, but she flexed into the touch, fully enjoying the sensation of horse filth being smeared across her body. The experience was akin to a mud bath she might treat herself to at the Ponyville spa, yet somehow much better. After all, no mud bath had brought her so close to orgasm without even touching her cunt. It was as if she was getting off from the depravity and filth alone, but she couldn’t be more content with that fact.

Sunset then brought one of the still intact horseapples close to Twilight face, a clear offering for her. Twilight accepted immediately, opening her mouth wide and allowing her friend to push the shit into her open maw. The flavor was far different than that of her own - Buck’s shit had a more earthy undertone to it, but the bitter flavor of poop was still there.

Twilight nearly gagged at the amount of it, and the intense flavor, but managed to hold it back as Sunset leaned in to kiss her. Sunset’s dirty, mucky hand cupped the side of her face as they made out, softening the horseapple down with their combined saliva and swapping it between each other’s mouths.

As they kissed, Sunset brought her other filthy hand down to rub at Twilight’s needy pussy. The gritty, slimy texture of shit smeared between her lips, adding to the pleasure Twilight was receiving. She moaned into the other girl's mouth, wrapping her own arms up and around the girl above her, pulling into a close embrace.

And then, with another flick of Sunset’s crap-covered fingers across her clit, Twilight came. Her body shook as she rode into her orgasm, juices squirting out of her pussy and across the stall floor. She held Sunset close to her, moaning into their kiss loudly, her mind overdosing on orgasmic bliss.

Sunset held her the entire time as Twilight rode out her last orgasm of the day, and she gently set the girl back down on her bed of straw as she stopped cumming, and quickly found her pussy with her own hand.

It didn’t take much effort to come - she had been edging for practically the entire session - but when she did, it was powerful. A stream of girl cum exploded out of her pussy, violently splashing onto the hay-covered floor and creating a puddle. The orgasm removed her sense of control, and as soon as she had finished cumming, a heavy stream of pale yellow urine began to pour out of her vagina. She sighed and leaned against the hay bale as she peed, relief, pleasure, and euphoria washing over her.

“H-how are you feeling now?” Sunset gasped out after a moment as she sat in a puddle of her own pee and juices. Both girls were filthy, exhausted, and out of breath, chests heaving as they tried to recover from their orgasms. “Twi?”

It took Twilight a few moments to respond, still drifting between consciousness and an orgasm-induced coma. “Y-yeah,” she stammered. “I feel g-great…”

“Satisfied?” Sunset asked, turning to look at her flushed friend.

“Yeah,” Twilight answered as her eyes slowly drifted shut. “You could say that…”

Sunset smiled to herself as Twilight finally drifted off, exhausted and finally satiated from her brutal bestial fucking. There certaintly was no cock like horsecock… especially as a human.

“I’m telling you, Rainbow, it was fucking massive!” Twilight said, signifying the length with her hooves.

Rainbow just nodded. “So you keep saying,” she muttered. “I still don’t understand how you got pregnant, though.”

Twilight looked down, and laid a hoof on her swollen belly. “I don’t know. Maybe there was some semen still left inside when I came back through the portal, and the mirror just decided to turn it into pony sperm or something.”

To be honest, Twilight really didn’t even think about it until she had started to show the symptoms of pregnancy. A quick magical test had verified that she was in fact bearing a foal, and she didn’t even question it.

“Maybe. Or maybe it’s still the same spunk from that horse thing and you’re going to give birth to one of those!” Rainbow teased, falling back and laughing.

Twilight, however, was not as amused. “I certainly hope not,” she said. “And besides, even if I did, I’m sure Sunset would take good care of it.”

Rainbow was still laughing though, not paying attention to what Twilight was saying. “And I stil can’t believe you actually shit yourself during sex! That’s…. That’s fucking priceless!”

The alicorn blushed. While she had told Rainbow Dash about her… accident, she hadn’t divulged the full story about her scatalogical experience. Then she grinned as something Sunset had said came back to her.

“Well, Rainbow Dash, laugh away,” she said with a smile. “But Sunset told me you did the same thing the last time your human counterpart got plowed by Buck, too!”

The pegasus’ laughter died down and a mortified expression came over her face. “You’re lying,” she said. “I… I would never… I’m too cool!”

Twilight just rubbed her pregnant belly and smiled gleefully. “Oh, I’ve been assured you did!” she shot back. “And what’s better is I’m told you enjoy doing it, too!”

Rainbow scowled. “The only reason I’m not pinning you down for some rough hatesex right now is because you’re pregnant,” she growled, crossing her forelegs.

“Mhm, sure, Rainbow. Whatever makes you feel better.”
