Sketchy Magic Always Pays Off

Sunset Shimmer (and co.) are presumed to be 18+ in this story.

Dashie: hmu after practice i gotta go. coach is flippin his shit

Shimmy: Ooo youre gonna get sooo sweaty in those tight pants!!! I bet ur not even wearing panties.

Dashie: [picture] u c any panty lines? also wat part of "hmu after practice" do u not undrstnd?

Shimmy: OMG I can see the sweat on your abs! You better not even be thinking of taking a shower!!

Sunset Shimmer bit her lip as she hit send, eyes glancing over the picture that Rainbow Dash had just sent. She could just imagine the scent, and her eyes nearly rolled back as she thought of it. She took another look at the image - Dash was right, there were no panty lines. As a matter of fact, the athlete was even sporting a tiny cameltoe.

One of Sunset’s hands left the steering wheel where it had been resting, and slowly began to trail down her body. Her fingers dipped past the hem of her skirt, gently lifting it up so that she could slip her hand under the waistband of her leggings. She wasn’t wearing any panties either, and her hand dipped past the small patch of fiery red pubic hair that she had been growing out to paw at her damp pussy.

The teen had always been quite envious of her girlfriend's abundance of pubic hair. Rainbow’s crotch was grown out like a forest - a feature that had taken quite a bit of time to accomplish. Sunset was trying her hardest to catch up. She hadn’t shaved in months, and had managed to grow out a sizable bush right above her pussy, and a couple tufts underneath both of her armpits. She was nowhere close to being as hairy as the athlete, but she enjoyed what little fur she had now.

Her fingers easily slipped into her wet slit, wriggling around as she toyed with her hole. Her thumb idly pawed at her clit and she pumped her index and middle finger in and out of her cunt, a wet schlicking sound grew steadily louder inside her car.

Sunset's eyes followed the few straggling students as they left the school and headed to their cars. Their presence and the idea that any one of them could look over and catch her masturbating pushed Sunset farther down the path of lust, and her pussy practically gushed at the idea.

Her pants limited the range of motion she had with her hand, however, and with a quick, fluid motion, she lifted her ass off of the seat and slid them down. Her bottom half now bared to anyone who dared peek inside her car, Sunset resumed her semi-public masturbation, bringing herself closer and closer to an orgasm.

Lyra and Bon Bon chose that moment to leave the school, and they walked right past Sunset's car as they headed to their own. Lyra gave the fiery teen a friendly wave as the duo walked by, completely oblivious to what the redhead was currently doing. Sunset gave a wavering smile in reply, waving with her free hand. Her other hand continued to play with her pussy - now pumping three fingers in and out of her soaked slit - their motions completely undeterred by the interaction. And they sped up as Bon Bon shot the girl a knowing smirk.

It was this acknowledgement that pushed her over the edge.

Sunset shuddered as she came. Her pussy quivered as a thick stream of her juices squirted out over the upholstery and splattered on the pedals between her legs. A low moan escaped her throat as she rode off the edge of her orgasm. She lifted her trembling hand out from her crotch and brought it up to her face and sniffed at her feminine juices before she stuck each finger into her mouth and licked them clean. The tangy flavor lingered on her tongue as she savored the taste of her own cum, making sure that each and every digit was clean of her pussy juice.

The fiery teen used her phone to pass the remainder of the time she had left until Rainbow's practice was over. Looking at kinky porn of course. She had just upvoted a picture of some whored-out pink haired girl girl huffing her pet Doberman's nasty shit-caked anus whilst licking its plump, wet cookie when the door to her car was abruptly pulled open.

“Fuck, practice was brutal!” Rainbow commented as she pulled open the rear passenger side door. She chucked her gym bag and backpack carelessly into the backseat before slamming the door shut and climbing into the passenger seat. She noticed then that Sunset was quite obviously not wearing any pants... or panties. "Heh, you've kept yourself busy, huh?" she commented with an amused grin as she yanked the car door shut behind her.

Her clothes were soaked through with sweat, and her hair was mussed up in the loose ponytail she had tied it up in. She stretched in her seat before she buckled up, raising her arms up over her head.

The action bared her armpits to the rest of the car, and the harsh scent of her body odor quickly filled the tight space. Sunset bit her lip as she eyed the hair-covered pit, her arousal growing at the sight. Rainbow grinned as she caught Sunset’s eye and deliberately lifted her arms higher and held them there, stretching the skin underneath her arms. The action was too much for the other girl to handle.

Sunset leaned over the center console and pressed her face into Rainbow's hairy pit. The tangy scent of sweat and body odor simmered in her nose as she huffed at the moist flesh. Damn, she wished she could get high off of this scent. She probably could get high off of this scent.

Reluctantly, she forced herself to pull away. While she'd love to keep her face buried in the athlete's hairy armpit forever, she did have special plans for this evening, and she would need to get moving now if they wanted to take part in them. Much to Sunset's delight, a glistening stain of sweat clung to the edge of her nose and even just idly breathing would grant her the sour scent of Dash's pit musk.

“Listen,” she breathed huskily. “I’d love nothing more than to huff your pit-stank all night, but I have something special planned.”

A raised eyebrow and a cocky grin met her proposal. “Oh? I thought we were gonna just grab some dinner and then maybe fuck all night…” Dash joked as she languidly groped one of her own sweaty breasts. “What might this surprise be?”

It turned out that she did not need to wait long to find out. Sunset started the car and backed out of the space, presumedly to head back to her apartment. But what surprised Rainbow was when she instead turned towards the front of Canterlot High and parked in the traffic circle next to the iconic Wondercolt statue instead.

"This will only take a second," Sunset said cryptically as she tossed her keys at Dash and stepped out of the car, pants still missing from her lower half. "You're gonna need to drive us back to my place though." She shut the door and walked around towards the statue. "Get in the driver's seat and close your eyes!" she called back before disappearing around the side of the plinth.

Thoroughly confused, Dash simply did as she was told. She maneuvered over the center console to sit in the driver's seat, and noted with amusement that the seat and pedals were slightly damp with what she presumed was her girlfriend's cum.

"Dash! Eyes!" scolded Sunset as she poked her head back around the statue, motioning an "I'm watching you” gesture to Rainbow. The athlete sheepishly grinned and gave a thumbs up before she squeezed her eyes tightly closed.

Ensuring that Dash's eyes were sealed shut, Sunset turned around the corner of the statue to carry out her plan... which seemed to take quite a while.

Rainbow sat there in silence. She shifted back and forth eagerly as she wondered what surprise her girlfriend could possibly have in store for her. Her mind conjured up strange, lustful plans in anticipation... a public striptease in front of the school? Maybe they would fuck on top of the car's hood in broad daylight? Maybe Sunset was going to take a sexy fat shit on the Wondercolt statue and then smear it everywhere as Rainbow masturbated furiously in the car? Her mind raced with all of the possibilities, and her pussy grew slick as she waited.

Whatever it was though, why did she have to wait so long for it?

Just as Dash was about to cheat and open her eyes to see what the hell was taking her girlfriend so fucking long, the passenger door opened. The abrupt noise startled her, and her head jerked to the side automatically even as her eyes remained firmly shut. "Sunset?" she asked. "Is that you?"

"Yep," came Sunset's voice, followed by some grunting. "It's me alright." Panting and huffing filled the left side of the car as the vehicle bobbed with the telltale shift of someone getting into the car. Although, it was taking longer than expected. Did Sunset have something with her? Why did it sound like she was having a difficult time climbing into her seat?

"Damn this is harder like this," panted Sunset as the door slammed shut. "Okay, Dash. You can open your eyes now."

"Fucking finally!" With curiosity burning through her, Rainbow popped her eyes open to finally see what all of the fuss was about. What she saw did not make sense at all.

Sitting in the passenger seat like a dog was a small, amber horse with a fiery red and yellow mane. A pointed horn poked up through the curls of her mane, and two familiar, teal eyes stared back at the athlete as she tried to comprehend what she was looking at.

"Hi, Rainbow," pony Sunset said with a coy smile. "Do you like your present?"

Rainbow's mouth opened and closed a few times before she could form words. "Bwah... uh... wha..." she stuttered, trying to pull together a cohesive sentence. "What?!" she finally managed to spit out.

Her girlfriend's reaction only made Sunset's smile widen, and she laughed in response. "Given our frequent... nighttime activities, and my own unique situation, I thought this might be a fun anniversary surprise for you," she explained. "Rather than fucking a horse with your girlfriend, you can fuck a horse who is your girlfriend." Suddenly, Sunset's smile turned a bit darker. "Or, more accurately, the horse who is your girlfriend can fuck you."

With the dominating grin still plastered on her face, Sunset leaned back against the seat in a way that should have been unnatural for a pony and spread her hind legs wide. Dash's eyes widened and nearly popped out of her skull as a massive horsecock comically flopped out from between the unicorn's legs and bobbed lightly in the air. The giant member was nowhere near as large as stallions, but it easily dwarfed the pony's small form. It was nearly as long as Sunset's torso, and was definitely larger than any normal human penis could be. Beneath the turgid member was a pair of equally well-endowed balls, draped against the cushioned seat and pulsed in time with the large cock as they churned with unspent cum.

"Oh my fucking god," was all that Dash could possibly say in response. A strand of drool threatened to dangle out of her open mouth as she desperately tried to take in the sight before her.

Sunset laughed in response, her penis swaying in time with her giggles. "I thought you'd like it," she said with a smirk. "Wanna touch it?"

"God yes," groaned Rainbow, and she reached a hoof across the center console to grab onto the horsecock.

But her hand was suddenly stopped by Sunset's hoof, and the mare tutted in disapproval. "Is this really the right place for this? Wouldn't you prefer to go back to your place? Where we have all the freedom to do whatever we want?" she asked. Dash desperately nodded in response, eager to get her hands on the small pony sitting next to her. With a satisfied chuckle, Sunset pointed a hoof at the steering wheel. "Drive."

Rainbow needed only one other instruction. "My place or yours?" she asked eagerly as she turned the ignition and began to pull out of the parking space, and peeled out of the school parking lot.

The decision wasn't a particularly hard one, and in a matter of minutes, they had pulled up in front of Sunset's apartment. It was a simple choice: Sunset, due to not being human and all, didn't have a pair of nosy parents poking their head in all the time. Also, she was nasty enough to not care about, and even relish in, whatever disgusting mess they were about to make all over her apartment.

Sunset quickly trotted into the apartment so as to not be seen while Rainbow locked the car and jogged after her. No sooner than Dash had shut the door, Sunset was already on her. The little pony, barely the size of a large dog, had reared up onto her hind legs and was pawing at Rainbow's gym shorts with her two front hooves.

"Get this shit off," Sunset huffed. "I could fucking smell you during the entire car ride... my cock is so fucking hard..." the small pony panted in between deep breaths. "Let me get my nose in that fucking ass!"

Rainbow giggled, and had it been anyone else at any other time, she might have been embarrassed by the sound she made. But not today. Today, she eagerly hooked her thumbs into the waistband of her pants and shuffled them down slightly to reveal only the top of her pantyless crotch beneath them.

Sunset immediately pressed her nose into the crest of Dash's hairy crotch, huffing the scent of her pussy juice, stank, and sweat as the coarse hairs tickled her nostrils. "Mmmmm," she hummed as her eyes rolled back and her mouth hung open. "Holy shit that smells so hot..." Sunset licked her lips, ready to dive in. "Oh my god turn the fuck around," she commanded.

Rainbow let out a surprised "oof" as magic gripped her hips and suddenly flipped her around and pushed her front into the wall. Her small breasts pressed up against the wood of the apartment's front door as the pony behind her dug her nose into the sweaty crack of her ass.

The scent unexpectedly sent Sunset reeling. She knew that as a pony her sense of smell had been slightly more acute than in her human form, but she had not realized just how much. Even through the stretchy fabric of her gym shorts, the shitty musk emanating from Rainbow's stained asscrack was almost overwhelming, and a thick fog clouded her mind as she breathed the fumes in. The foul, earthy scent was drawing her in closer and closer, and the last vestiges of her resilience were slipping. Nearly losing her mind to her own lust, Sunset pulled away, lit her horn, and quickly yanked on Rainbow's sweat-soaked shorts, baring the athlete's crack to the world.

The damp fabric peeled away and slid down Rainbow's legs, and Sunset cooed at the sight of her girlfriend's bare ass. Her magic refocused to the two cheeks, and she gently spread them before her. What she saw made her mouth water with lust, and she inhaled deeply at the sight. Dash must not have wiped for weeks before this. Clumps of shit, both crusty with age and more recent greasy smears clung to the hairy crevice around her butthole. She lunged forward, barely able to hold herself back, smashing her muzzle up in between the athlete's cheeks.

Sunset moaned and huffed as the stale scat smeared across her muzzle and nostrils. She buried her nose even deeper into the crack of Dash's ass, pressing her nostrils into the messy pucker and inhaling deeply. The gross stench overwhelmed her already lust-filled mind, and she salivated at the sensation. Unable to help herself any longer, Sunset stuck out her tongue and pressed it directly against the girl's nasty butthole.

Her tongue dug into the filthy pucker, and Sunset's eyes rolled into the back of her head in pleasure as she licked the vile, crusty sludge off of her girlfriend's wrinkled flesh. The coarse hairs ringing her anus scratched at her tongue in the best way, and the unicorn just kept swirling her oral organ around in circles as she cleaned the pucker of its filth. Even with how much there was left behind, it was only a moment before most of the disgusting shit had been relocated from the sweaty anus and into the pony's eager mouth. All the while, Sunset kept inhaling deeply as if she had been deprived of oxygen for hours on end, the sound of her sharp inhales mixing with the vicious slobbering of her mouth on Rainbow's ass combining into a symphony that sounded as if it had been composed by a rabid dog.

Rainbow cooed as the pony lapped at her ass, and she made sure to flex her anus a few times to encourage Sunset to go even deeper. The pony obliged, and drilled her tongue deep into Rainbow's ass - the oral organ squirming its way past the athlete's tight, hairy asshole and burrowing deep into her rectum.

"Holy shit," moaned Dash. "How long is your fucking tongue?!" Sunset merely swirled her tongue around more forcefully within Rainbow's ass, scraping leftover fecal slime from the inner walls of her colon. It was enough of an answer for Rainbow, as the athlete's eyes rolled back in pure pleasure.

It was only after several long minutes of intense anal worship that Sunset pulled her head out of Rainbow's ass to come up for air. Dash took the opportunity to look down at her pony girlfriend and cracked sultry grin at the sight.

Sunset's mane was very disheveled, with stray strands flying every which way outwards from her lust-drunk face. Her muzzle was smeared with streaks of dark brown shit and stray butthole hairs, the fur around her face matted down with a combination of Rainbow's sweat and drool. And it was all topped off by the absolutely dopey , blissful grin that crossed her face.

With the image before her, the temptation to kiss Sunset was too great for Rainbow to resist... so she didn't. The tall athlete crouched down in front of Sunset and grabbed her small, equine frame to bring her close before pressing their lips together in a filthy, wet kiss. Her tongue worked her way around the pony's lips, swiping a generous taste of her own shitty ass off of her girlfriend's mouth before slipping inside.

The kiss quickly pulled Sunset out of her haze, and she reciprocated in kind. Their tongues danced around each other as they swapped saliva and scat with each other, wrestling for dominance over the other. They tried to deepen the kiss further, practically shoving their tongues down each other’s throats.

Still locked in their passionate kiss, Rainbow lifted the small pony up from the ground and carried her through the living room and into Sunset's bedroom. She broke away from the pony’s mouth only to deposit her on the bed and then climb on after her. As she fell onto the sheets, Sunset wriggled around playfully on her back, her horsecock on full display. The large organ was draped across her belly, and Dash couldn’t resist reaching down to wrap one of her hands around it.

The heat of the penis warmed the athlete's palm as she gently gripped the length. “Oh, wow,” she breathed as she simply let the phallus rest in her hand for a few moments. She gave it a slow, tentative stroke and Sunset let out a small gasp at the motion.

Her dick was already as hard as it could get, and it pulsed steadily in Rainbow’s hand. The girl smiled as she began to stroke faster, making Sunset moan louder. But, just as she started to work up a steady rhythm she let go of the cock and stood back with a teasing grin. Sunset looked up at her in confusion.

“That’s enough of that for now,” Dash said with a sultry grin. “Let’s see that horsey ass of yours.”

The small pony’s confusion shifted into a similar sultry look as she grinned widely as she stood up on the bed. “I guess you have waited long enough,” she teased as she turned around. She arched her back and flipped her tail up and over, baring her rear to the human behind her. The action put her entire ass on full display, from her pronounced pucker, darkened taint and large, full testicles, all the way down to the long, equine cock that dangled low below between her rear legs.

Ready to dive in, Rainbow climbed on the bed behind her and kneeled down to bring her face level with the pony butt in front of her. She reached up and grabbed either side of Sunset’s flank with her hands and pulled it closer to take in the beautiful sight close-up.

Sunset's anus was nothing like her human one - nor was it quite akin to the horses that Dash had rimmed either. In her pony form, Sunset's pucker was plump and pronounced, and its wrinkled flesh stood out between her toned flanks like a large, steaming donut of musky pleasure.

Rainbow pressed her nose right into the middle of the surprisingly soft flesh and inhaled the ripe, bitter scent of the mare's ass deep into her nose. "Mmmf, holy fuck you smell so good," she mumbled, her mouth moving against the firm, sweaty taint below the anus.

Sunset chuckled. "Oh, you think it smells good now?" she asked playfully. "Then you're going to love this!"

The doughy ponut flexed a few times against Rainbow's nose before a long, wet fart ripped out. The rancid air was forced right up Dash's nostrils, and she shuddered as the foul scent was channeled directly into her brain. The fart caused Sunset's butthole to gape just enough for Rainbow's entire nose to slip in and get trapped as the tight hole clamped back down around it.

"Heh heh, got your nose!" Sunset giggled as she clenched her ass a few times around her girlfriend's nose. Rainbow's eyes rolled back into her head as she vigorously huffed the fetid fumes right out of Sunset's rectum, and her tongue lolled out against the pony's taint in pure pleasure.

Although she enjoyed huffing her pony girlfriend’s ass-stench, Rainbow was eager to move things along. Her mouth had been pressed up against Sunset’s musky taint the entire time, and her tongue had slipped out a few times to sample the moist, sweaty flavor that stewed around her equine genitals. Rainbow was craving more of that flavor, and she knew exactly where to get it.

Dash’s face trailed down the rear of Sunset’s ass. Her nose left the warm doughy flesh of the puckered ponut and slid down the musky taint as her mouth came to a stop just below the full, churning balls of her girlfriend.

Without wasting any time, the athlete’s tongue slid out and slobbered along the underside of Sunset’s smooth, round orbs. She relished the leathery, musky surface of each of the pony’s balls, and she slurped each of the large testicles into her mouth in turn. Dash sucked on them, applying just the right amount of pressure to make Sunset moan lustfully before she let it slip out of her mouth and planed a firm, wet kiss on it and moved on to the next.

“Jesus,” Dash mumbled through her slobbering. “These are some hefty nuts.” She ran her tongue in between them, lifting their weight and relishing the taste of sweat and stank on them.

Above her head, Sunset’s anus flexed again and let out another airy fart. The noxious gas sputtered out of her ass, and then suddenly, a small horseapple slipped out and fell onto Rainbow’s head. The tiny turd quickly rolled off and fell to the sheets below, but Rainbow pulled back in surprise just in time to watch as Sunset’s ass opened up.

The pony quickly squatted down as her butthole spread wide around the head of a large, round turd. It poked out of her parted pucker as it slowly dipped out. It was large, and it stretched Sunset’s ponut nicely. But as the unicorn pushed, it slid all of the way out and dropped onto the bed.

That first horseapple was just the beginning though, as a loud, booming fart signaled that there was more to come. Her anus opened up and began to drop large mounds of crap onto the sheets, and Sunset moaned as each passing log smeared fecal residue on her sensitive pucker as it slid out. She resisted the urge to reach out with her magic and start masturabting at the intense pleasure of relieving herself, and instead focused on dropping as much horse shit as she could on top of her sheets.

Rainbow Dash's eyes widened at the growing pile of shit mounding up in front of her. The fetid stench of poop filled the room quickly, and her nostrils flared as she sniffed at the foul odor. The noxious perfume was delightfully potent, and Dash happily breathed in the air around her as she watched the pony continue to squeeze out massive logs of poop onto the sheets before her. How did such a small body produce so much crap?

Sunset grunted as another horseapple stretched out her anus and tumbled on top of the pile. "Hnnng! If there's one thing we ponies are good at, Rainbow... it's making shit!" she said, as if she were reading her friend's mind. An airy fart hissed out of her stained butthole and blew against Rainbow's face as the girl leaned in closer.

The warm pile of pony poop had created a sizable depression in the sheets as the material dipped down under the weight. The familiar fetid stench of horse shit had filled the room, and would most likely permeate the sheets for the coming days, if not weeks. Dash would definitely be staying the night more often in the near future, if only to be bathed in this warm, foul odor.

"Do you want a taste fresh from my ass, Dashie?" Sunset asked sweetly as she flexed her anus a few times just to tease a tantalizing view of the next, large horseapple in her rectum. Rainbow nodded eagerly as she leaned in with a whispered "oh fuck yeah" under her breath. Sunset grinned and took a few steps back, over the pile of her shit, and arched her back slightly to give Rainbow a better angle.

Rainbow didn't waste any time in positioning her mouth right against the ponut and opened it up wide, ready for the deposit that the pony was about to make. Sunset flexed her pucker a few times and the wrinkled flesh parted around the promised turd. The ball of digested hay quickly squeezed its way out of her colon and right into Rainbow’s mouth with a low, wet crackling noise. A few hisses of gas escaped out after it, blowing into the athlete’s face, adding additional olfactory stimulation to the already fetid odor permeating the room.

The taste of fresh horse shit never got old to Rainbow. The nasty, bitter flavor of digested hay and grass combined into a foul treat that she could only get from a horse's wrinkled pucker. But the taste of Sunset's scat brought the experience to a whole different level. Mixed in with the usual, disgusting flavors were new and unique undertones of sweetness - likely from her pony girlfriend's human diet mixed with whatever it was she had consumed when last she was fully equine.

Rainbow bit down into the muck and smeared the fetid paste around in her mouth. She pulled back away as she chewed, and Sunset lowered her ass back down. Rainbow watched as Sunset squeezed out the last of her bowel movement onto the pile on the bed. Wow, dinner and a show!

With her colon finally empty of shit, Sunset playfully shook her ass and tail at Rainbow before she made to turn around and face her. But, before she could actually get moving, she felt a pair of hands grab either side of her rear and yank her backwards. The unicorn let out a surprised yelp as Rainbow leaned forward to dig her tongue into her dirty anus, forcefully cleaning it of its smelly filth.

The athlete let out a muffled moan as her tongue scraped poop from the wrinkled surface of Sunset’s pucker. The sour, putrid taste that lingered in her mouth from before was only amplified by the reintroduction of fresh, leftover filth straight from the source. There was something so primal - so defiling about licking literal shit off of an animal’s ass that warmed her pussy right to the very core. The fact that said animal was literally her girlfriend only heightened that intense feeling of lust, and Rainbow was more than happy to fully lean into the feeling.

Her pussy dripped out onto the sheets between her thighs as she slurped the last of the fetid muck from Sunset’s butthole, and with one last flourish of her tongue, the pony’s anus was practically spotless. Dash leaned back with a breathy gasp, licking the brown, fecal residue from her lips as she finally let go of the small pony before her.

Sunset chuckled as she stepped away and turned around. “My, my! It seems like someone just can’t get enough of my chocolate today,” she teased as she watched her girlfriend lick her lips. “Good thing there’s a whole pile right here!” She gestured with a hoof at the large mound of horseapples sitting on the bed. “Or… maybe we could try something else I had in mind?”

Rainbow watched as Sunset shifted her legs to reveal her hard, throbbing horsecock. Somehow, it appeared even larger than it had previously, and Dash had to concentrate very hard so as to not start drooling at the sight. This task was made even more difficult by what Sunset did next.

With a coy grin, Sunset took a step forward so that she was positioned directly above the pile of manure that she had just produced. Then, without any hesitation, she bucked down and slid her dick right into the soft pile of dung. She gasped as her cock pushed into the warm mound of shit, and she closed her eyes as she began to gently thrust. Greasy, fetid muck smeared onto her length as she pistoned in and out, and whole chunks of poop got caught on her medial ring and bulbed flare. For her part, Dash merely reached in between her legs and began to play with herself as she watched her pony girlfriend literally fuck a pile of shit on the bed in front of her.

Each downward thrust not only coated her dick in warm muck, but also spread the crap out onto her previously pink floral sheets. Large streaks of brown smeared out onto the bed, undoubtedly permeating its filth and stench into not only the sheets, but most likely the mattress as well. It would take days if not weeks to get the disgusting scent out of the fabric, and Sunset would want nothing less. After a few more thrusts, Sunset was satisfied that her rod was nice and well coated, and pulled fully out of the mess.

Sure enough, her dick was fully lubed with thick, chunky horseshit, and she grinned as she took another step forward towards her girlfriend. “You know the drill. Bend over,” she ordered huskily.

Rainbow would never even think to disobey that order, and quickly rolled over to present her bare ass to the pony behind her. “Saddle up, cow girl,” she said as she wiggled her behind enticingly.

Sunset reared up and waddled forward. She placed her forehooves on the small of Rainbow’s back and lined her stinky dick up with the athlete’s waiting pussy. Then, without waiting any longer, she slid it in.

A loud moan ripped its way out of Rainbow’s throat as Sunset’s shit-coated dick penetrated her. The thick length, lubed only by her own crap, pushed deep into Rainbow’s pussy. Even with its immense size and length, the shape somehow matched perfectly, like a key sliding into a lock. In some back annals of Dash’s mind, she recognized how romantically poetic that may be, however she had no way (or desire) to express that sappy shit right now. Right now, she wanted to be fucked.

And fucked would she be.

Sunset quickly picked up the pace. She pulled out and slammed her hips back into Rainbow’s ass over and over again. The action created loud squelching noises and wet slaps that combined with Rainbow’s frantic moaning to create a lewd, debaucherous orchestra of coital filth. They lost themselves first to the raw pleasure, and then, Rainbow lost full control of herself as the action down in her pussy awakened a biological need at her backdoor.

Dash let out a sex-fueled cry of pleasure as her colon began pushing on its own. Her anus flexed in time with Sunset’s thrusts for a few moments before it suddenly opened up to squeeze out a soft deluge of warm, wet shit. The waste was formless, oozing out of her puckered ass and all over her taint, pussy, and Sunset’s already filthy horsecock. Wet splutters and farts joined the lewd cacophony as Dash’s bowels emptied out behind her.

Chunks of fecal slop fell onto the bed, joining Sunset’s pile. The rest began to rub into the fur around the pony’s crotch, and smeared off on the round, supple flesh of Rainbow's ass. The scent of fresh diarrhea filled the room as well, and Sunset huffed the stench greedily as she picked up the pace of her frantic thrusting. She was going to cum soon.

“R-rainbow,” she grunted. “I’m getting close!”

Dash grunted and suddenly pulled away from Sunset. “W-wait,” she gasped. “Do it… do it on my face!” She crawled forward and pushed her face into Sunset crotch so that her cock draped languidly over her face and smeared the wet scat across her cheeks, nose, and horehead. Rainbow lolled out her tongue and slurped at the mixture of and her soft, wet poop mixed with Sunset’s horse scat and the salty tang of her own pussy juice.

Sunset was more than happy to oblige her girlfriend’s request, and gripped her cock firmly in her magic and began to pump. The unicorn's balls slapped loudly against her thighs as she masturbated onto Dash’s face, and it only took a few moments before she moaned loudly as she came. Hard.

As Sunset’s cock pulsed in orgasm, Rainbow leaned back to catch the first streak of thick, white cum along her face. What could only be called a deluge of horse semen followed it, exploding out across the girl’s face in hot, heavy strings. Some of it soared right over her head, landing on the sheets and hardwood floor behind her.

She leaned forward and wrapped her mouth around the wide flare of Sunset’s cock to catch the last of her ejactualteright in her mouth. The heavy, salty taste mixed with the fetid, earthy flavor of both human and horse shit, and Rainbow savored the potent mixture as she swirled it around her mouth. Her tongue tickled the open hole of Sunset’s urethra, coaxing the last of her cum out and into her eagerly waiting maw.

Slowly, Sunset came down from her orgasmic high, and pulled her softening dick out of Rainbow’s mouth. Rainbow held her mouth open so that the unicorn could see the disgustingly foul mixture of shit and cum in her mouth, and she even blew a few grotesque bubbles just for fun. Then, making sure that Sunset’s eyes were locked on her, she closed her mouth and swallowed. Sunset’s dick twitched as Rainbow opened her mouth back up to show that it was empty.

The two of them collapsed onto the bed, absolutely spent. Their bodies were covered in sweat and each other’s shit, and a blissful look lingered on each of their faces.

“Did you cum?” Sunset managed to ask. “I didn’t get to finish you off…”

“Fuck yeah I came,” said Rainbow, and she reached between her legs. When she brought it back up, it was soaked wet with her pussy juice. “If that doesn’t convince you, look at the sheets. Either I came or I pissed, and right now I don’t really care!”

Sunset smiled as she leaned forward to lick gently as Rainbow’s hand. The athlete spread her fingers to let the pony get at all the wet spots and she smiled.

“Holy fuck,” Rainbow whispered as Sunset laid back down. “Best. Anniversary. Gift. Ever!”

Sunset chuckled. “I’m glad you liked it, Dashie,” she replied softly. Then, she turned over to face her. “Now… what’d you get me?”

Rainbow’s face paled “Fuck…. I-” she trailed off as Sunset began to laugh.

“Don’t worry, Dash,” she said as a slightly evil grin spread across your face. “I think I know how you can make it up to me….”

Dash gulped as Sunset suddenly rolled over on top of her and turned around. Her ass lowered down over Rainbow’s face, and her horn lit up as she began to speak. “Cadence was kind enough to teach me this spell the last time I visited Equestria…”

Rainbow tuned her out as the stained ponut above her opened up, and the head of a large, soft turd began to slide out right onto Dash’s face.

“Oh, fuck yes!”
