Nah, I leave it all up to you, so I guess stop before then.

Fraternal twins, sister is dominant and happily will use a strapon as much as go natural.
She is fairly predatory and would enjoy making a meal squirm more than just gulp and go.
Brother is submissive to a point, not roll over and accept it, but goes with it when he knows its time.
He likes to be put in bondage during play rather than just straight vanilla.
Both enjoy wearing and using diapers for pleasure, not need.
They have their own house, but like doing their stuff in public more than private.
Not clandestine either, they prefer to get crowds watching them have sex or do vore or anything.
----
Naarkessex and Naarkerotics were a pair of fraternal twin ponies, one a mare, and one a stallion. They were far, far more physically intimate than most siblings ever dared to be. They were both incredibly kinky, beyond their tendency towards incest, with Naarkessex favoring the use of strap-ons to peg her more submissive brother, and both enjoying diapers for pleasurable purposes. They had a tendency to put their adventurous sexual escapades on public display, and this time was no different, as the two ponies found themselves in the middle of a crowded street.
They were both winged equines, with both their feathers and fur colored orange. Their bodies were what one would expect of a pony, four legs, each ending in a cloven hoof. They had vibrant blue hair as well. Naarkerotics had a teal streak in his, while his sister's was partially white. They both shared emerald green eyes. Naarkerotics, of course, had an equine cock, pure black in color.
"Come oooon," Naarkessex said, her voice teasing and playful, winking at her inattentive brother and nudging him with her hoof.
Naarkerotics sighed. He had grown used to her sexual accosting at this point, even in public, in full view of everyone, like she was doing now.
"Be quiet," her brother said, trying to keep the attention away from him and his visibly lusty sibling. Despite his submissiveness, he showed clear signs of arousal. Swear accumulated around his forehead, and a crimson blush spread across his snout.
"I know you want it, don't pretend like you don't," she continued, loudening her voice to thwart his attempt to keep things on the down-low. Naarkerotics winced as the other ponies began to stare.
Naarkerotics was typically the submissive partner, but he wouldn't let himself become a complete pushover either. He wasn't in the mood, and no amount of pestering could change that. Naarkessex knew this, which is why she shifted from simple pestering to more blatant seduction.
She turned away from him, so her rear was pointed in his direction. She wiggled it back and forth, seemingly unbothered by the fact that more and more of the surrounding ponies were beginning to watch her display. Naarkerotics tried to avert his gaze, but he couldn't keep his eyes off of the jiggling flank in front of him. Damn, why did his sister have to be so good at this? It was becoming more difficult to resist her advances by the second. He bit his lip, and inhaled sharply. His sister smirked, noticing that his defenses were starting to break down.
Naarkerotics could feel his equine cock throbbing between his legs as it began to stiffen. Fortunately for him, he stopped just short of getting a full-on erection, which was good given that the size of his cock, when erect would be almost impossible to hide.
"Oh, starting to get hard?" she said, continuing to jiggle her rear back and forth. "I thought you weren't interested."
"That doesn't mean anything!" he retorted, trying his best to slow the growth of the bulge between his hind legs. "The answer's still no!"
"I guess I have to get really extreme then," she said, backing up, her still-shaking ass getting even closer.
"W-what does that mean?"
"You'll find out soon enough," she said, her voice somewhere between a threat and a promise.
His sibling produced an unusual garment from hammerspace, a thick white diaper that was exactly her size. Naarkerotics covered his face with his hoof, he couldn't stand to look. The surrounding ponies became even more intrigued by this increasingly kinky display.
"Don't I look just absolutely perfect like this?" she said, donning the diaper and continuing to wiggle her ass, filling the air with the sound of lewd crinkling. "I must be even sexier than I was before. Don't you think?"
She got closer, backing up her padded rear into her sibling's face. Every hoofstep she made resulted in an echoing crinkle for the crowd to hear. Even those who didn't have a direct line of sight to the siblings could infer what was going on. She rubbed the crunching plastic against his snout, and her brother was helpless to do anything about it. A ripe fart with a supremely pungent odor pierced through the diaper's clean, powdery smell and into Naarkerotics nose.
He gagged, and tried to back away, but his sister was prepared for this, and backed herself up right back into his face.
"Ugh, gross!" he said. Unfortunately, talking meant that he had to open his mouth, which allowed some of that dreadful smell to slip in, which he immediately regretted. While his body language and his words conveyed revulsion at his sister's flatulent assault, his cock seemed to say otherwise, as it was growing more and more erect with every blast she produced.
"Come on, don't pretend like you don't love my stink," she said. Every gust of air propelled the hot scent of her unwashed ass directly into his helpless nostrils.
"No, it's disgusting!" he fired back. Her rear was revolting, even without the added odor of her farts. Her rear carried with it a heavy, musky, sweaty smell, and it was clear that she rarely, if ever wiped. Her diaper did very little to shield him from the stench. There was a kind of radiating warmth that surrounded it too.
While a part of Naarkerotics found her smell to be extremely upsetting, he couldn't help but take the occasional sniff. The mixture of odors was just so fascinating.
"Come on, I can feel you sniffing against my butt," she said. "Just admit that you love me, and my stink, and that you want to do all sorts of nasty things in front of all these other ponies."
"Never!" he said.
She sighed, letting out a deep, heavy fart into her diaper as a sort of punishment for his stubbornness. His gagging and sputtering let her know that it had worked.
"Are you sure?"
"Yes!" he said, once the particularly nasty fart she let out finally dissipated in the air. Many of the surrounding ponies either left, or walked away. As curious as they were about the two siblings bizarre interaction, it wasn't worth inhaling a lungful of stink to do it.
"Well, fine, I guess I have no choice. I'll just have to make you do it myself."
She undid the tapes on her diaper, and removed it carefully, allowing the stench of her ass to flow into the open air unimpeded. She kept the diaper wrapped up neatly, because she knew she would end up needing it again very soon.
Naarkerotics never thought he'd be longing for her to put her diaper back on, but her visibly pulsing butthole smelled much less appealing without that layer of plastic in the way.
"What, you don't like my stinky, unwashed ass? That sucks, because you're about to become a lot more familiar with it really soon!"
She pressed her greasy, disgusting hole right up to her brother's face. The smell got worse, as the putrid hole began to widen, drawing Naarkerotics head inside. He was dragged slowly towards her bowels by her sucking insides.
"Is she...eating me with her ass?" he said in shock, both at the fact that this was happening, and the fact that he was in a situation where that sentence made sense to say out loud.
He was correct, however. She was indeed devouring her beloved sibling through her anus, and judging by her ceaseless moans and the crimson blush on her cheeks, she was having quite a lot of fun with it too.
Naarkerotics, of course, wasn't having nearly as good a time. His sister's ass was clearly seldom, if ever cleaned, and stunk of the sort of things that you'd expect an ass to smell like. Somehow, it was even worse than her farts, as there was no fresh air to escape to. Every breath would result in a mouthful or noseful of ass stench, and there was simply nothing he could do.
He made a token attempt to struggle, but deep down, both siblings knew that it was pointless. Her ass was like a vaccuum, the powerful muscles drawing him inside, closer and closer to the final destination that was her stomach.
"You know, I considered eating you the regular way," his sister teased, her voice just barely audible audible to her sibling. "But I think this is so much more fun. Don't you agree!"
Naarkerotics was tempted to let out some venomous retort, but he didn't want to risk opening his mouth and risk letting more of her disgusting butt-fumes inside. The crowd was fascinated, they had never seen anything like this. Many simply couldn't believe what their eyes were showing them. Some considered calling the authorities to get help for the poor pony who was being devoured, but they didn't want to risk anyone else falling victim to her nasty, cavernous ass.
Naarkasex was visibly drooling. Thick ropes of her saliva dribbled onto the pavement as her mouth hung open with pure bliss. The feeling she was experiencing was incomparable, it was like having anal sex and eating a delicious, filling meal all combined into one unbelievable sensation.
"Ah, this is...the best feeling!"
Naarkerotics was having significantly less fun. The closer he got to his final destination, the worse the smell became. Still, things weren't all bad. The way his cock felt when it was enveloped by all that supple ass flesh was actually rather nice, but he was too preoccupied with the fear of digestion to savor it.
Naarkerotics finally entered his sister's stomach with an audible plop. It was just about what he expected: wet, tight, and filled with digestive juices that made his skin tingle. He expected the tingling would soon turn into burning after he'd stewed in there for a bit longer.
He pressed his hooves up against the lining of her stomach, struggling and thrashing his body around in the enclosed space.
Naarkesex's stomach gurgled from the outside, the bloated, orange orb imprinted with a vague outline of her brother's struggling form. She loved the struggling most of all, not only did it feel great on a purely physical level, but it made her feel like a powerful, superior predator too. She knew that, no matter how much he tried, he'd never be able to escape.
"Come on...you wouldn't really digest me, right sis?" he whined. He was growing tired, and his struggles were beginning to subside.
"Of course I would! What's the fun in eating someone if I can't churn them into nutritious sludge, and push the rest out of my ass in a big, smelly pile? It's like sex without an orgasm! That reminds me, you gotta keep struggling! You're going to get digested anyways, you might as well put up a fight, and give your sister a fun time while you do."
He was hesitant to give his sister any pleasure, but she was right, there wasn't much of a reason for him not to. He took a deep breath, and fought even harder than before, putting all of his might into every punch, kick, and thrust.
Naarkesex was elated. She felt like the ultimate huntress; even her big, strong brother, using all he had, wasn't enough to escape from her mighty stomach. And the punches and kicks themselves filled her belly with a lovely tingling sensation.
Naarkerotics was beginning to enjoy himself too. He expected digestion to be a horrible, painful process, but the tickling of her acids only got more enjoyable the more he stayed there, instead of becoming more painful. It was a bit like a bubbly hot tup, enveloping his entire body in warmth. His skin softened, and his muscles dissolved, as the acids slowly ate away at his flesh. He was her meal, and soon, he would be nothing more than shit. Diaper shit to be exact, if he was correct about what his sister had in mind for him. He was surprisingly aroused by this thought. He always loved his sister's messy diapers, so the idea of becoming the mess weighing down her pampers was a serious turn-on.
He closed his eyes, as he could feel himself slowly melting away into nothing. Eventually, he was too soft, too tired, and too contented to struggle, and that's when his sister knew that her brother was almost completely digested.
"You were a really fun meal," she said with sincerity. "Hopefully you'll be just as fun for the part that comes after."
Naarkesex took the discarded diaper, and put it back on over her exposed rear.
"Alright, shouldn't be long now!" she said. She could feel her brother's digested remains moving through her digestive system, towards her bowels. She spread her back hooves apart, allowing some room for what came next. Some of the observers in the crowd could guess what was going to happen, and others were utterly shocked.
Her cheeks turned red, as she began to squeeze. A conspicuous bulge appeared in the seat of her diaper, which continued to grow as she grunted and strained. "Whew! You're going to take a looooong time to push out~ Just how I like it!"
Her diaper sagged between her hind legs to accommodate the growing mess. Most of the crowd had deduced that the load that was filling her diaper was what remained of her devoured and digested brother. Undigested bones were visible through the stretched, bulging exterior of the once-white diaper. Her nappy had a dark brown stain towards the rear, where the mess was most prominent.
She reached a hoof back, pressing it against her bulge, which produced a loud crinkle, followed by a wet squish.
"Wow bro, you really made a huge mess!" she said with a giggle.
The diaper continued to droop, until it nearly touched the ground, sitting just above her hooves, swaying between her legs as she moved. The mess, of course, had a very strong smell, which kept the crowd at a considerable distance as she walked through them, back towards her home. She was an exhibitionist, sure, but at the moment she was craving a bit of privacy.
She made the trip back to her home in a relatively short amount of time, although the heavy turds that were once her brother made things take a bit longer than usual.
She slipped in, and immediately plopped herself onto the couch, in front of the TV. She leaned back, with her crotch pushed forward, giving her front hooves access to both her crotch, and the diaper mess just below it. She squished her hoof against the steaming mess, before moving it upwards, giving her pussy a rub through the thick padding. Of course, she was still able to feel it, even through all that fluff. In fact, the diaper material felt extra good as it brushed against her pussy.
She continued to rub herself, her mind abuzz with a chaotic series of erotic thoughts. Today had been so fun, she had indulged so many of her favorite fetishes, and now her brother was relegated to a mess in her diapers for the rest of time. The mess felt so warm, so squishy, and so good. Her asshole still felt some of the lingering stimulation of devouring her brother, and the subsequent shit it forced out.
"Ah, you should be happy," she said, addressing the mess that was once her brother. "You get to make me cum one last time."
She had an explosive orgasm inside of her diaper, the front of the padding absolutely soaked with her sexual juices. She let out a long, sultry moan, eyes fluttering as she leaned back in utter bliss.
"That. Was. Amazing," she said.
----
Once she was done reeling from what was perhaps the best orgasm of her life, she took off the diaper, and disposed of it the way she would any other, tossing it into the nearby diaper pail. She cleaned herself up, and then plopped her newly-freshed butt on the couch, treating herself to a bit of TV to end the wonderful night.
