As Bon Bon walks into Lyra's exploration of the creatures known as humans, she is shocked to find her Bestie in a diaper

Written as a birthday gift for Bright Foal.

Lyra is obsessed with humans. Bon Bon has accepted the fact. And sure, sometimes that obsession for them makes her stand out. Bon Bon still remembers when she started wearing that hoodie she always wears.

She wasn't however, expecting her to start wearing diapers. Apparently humans wore them, even as adults, and while she has an explanation ready made, Lyra is sure to involve her in her latest research.

This story contains: Padded ponies, diapers, oral sex, more diapers.

Diapers and Research

“Well that’s a surprise! You know that our foals wear them as well.”

“But they looked older, like almost Granny Smith old.”

Bon Bon glanced around, fearful that anypony would glance at the both of them. Granny Smith might not have the ability to pop up when her name was mentioned like Pinkie Pie had, but she still better be in the side of caution. Especially when Lyra insisted on wearing such things. Really the hoodie had been weird, but she had accepted it. Lots of ponies wore clothes, it was how Rarity made a living, but this?

“You know it’s surprisingly comfortable, maybe you should try it!”, Lyra was acting nonchalant about the whole thing. Really she was no stranger to all the different garments that humans wore. And while she was surprised by some of them - who wore latex - she still found it pretty interesting. Just a part of her studies.

She had of course recognised the object, she had worn one as a foal, as Bon Bon so tactfully pointed out. Bon Bon who, as soon as she had seen her roommate and best friend had flipped every door closed and shut the blinders on the windows. At first Lyra had thought this to be one of their kinky “Best friends” sessions, but Bon Bon had shouted horrified. They were still in the dark, though all that Lyra could feel was the weight of the diaper against her rump. With a hole for her tail it was surprisingly comfortable. It felt natural like it was something she should be wearing. Maybe that was why humans wore it.

“I am not going to wear them!”, Bon Bon’s face got real close to Lyra’s and she realised that maybe a lighting spell could help. Her vision was suddenly invaded by the muzzle of the other pony who wore a dissatisfied frown.

“You’re really cute when you’re angry.”

Bon Bon didn’t budge, through maybe her expression lightened somewhat, Lyra couldn’t tell. It looked like she wasn’t really going to get her session of play time between best friends after all.

“Flattery will get you nowhere, take them off!”, Bon Bon passed a hoof through the padded bottom and Lyra’s entire world went dark. It was not only the spell that turned off, it was her entire being. Her legs shook and she could barely stand. Her nethers tightening, and loosening. A feeling that started small, small in her chest, but grew and grew until she couldn’t contain it. Lyra didn’t know why she would ever want to contain it. It felt amazing, sure Bon Bon had made her cum, and she had done the same. But this was an entirely different thing entirely. It felt like her whole body shook, it felt like she came up into the skies and then back down.

It was the best Lyra had ever felt, and she could feel the copious amounts of juice leaking, in fact, as she fell on her rump they dampened her fur, never, ever smearing the floor. This was an unexpected bonus.

“Lyra what did-”, Bon Bon smelled the room and gasped. Sure Lyra was a quick trigger, but this was maybe a tad too quick. What had happened? It was clear that she had had a mindblowing orgasm, but from what? The diapers? From what she had told her they weren’t a sexual thing - Bon Bon had heard of such practices, practiced deep in the dark of the night, in the alleys, by worker ponies, but never had she expected her “Best friend” to get into it.

Lyra wore a dopey grin as she lighted up the room. All of her was a mess, her mane was disheveled, her eyes wore a searing expression of pleasure, and her hooves couldn’t hold her weight. She just sat, sitting against the fluids Bon Bon had so freely made run. Not that Bon Bon could see them, but she could feel them, hanging around. It was a wonder that she didn’t stink up the whole room, or release her urine. Her inner muscles still convulsed, trying to milk every last drop of pleasure out of that touch. If just being touched with a nappy felt this good, then imagine actually engaging.

She could totally see why humans performed such activities, wearing those thick diapers. It also made a pretty thick pillow. So she didn’t have to sit her bare rump on the floor. Despite the fur sometimes she could still feel the cold, not so with those on. It was similar to the underwear that she once had worn and that had made Bon Bon drop her spoon mid bakery cooking, but this one covered her entire rump. It felt nice. Lyra was aware however that Bon Bon didn’t seem to like it. In trying to convince her otherwise - a whole new use for diapers was discovered. - she found her tongue tied, she could only pronounce one single word.

“Whoah”

And, with that, her bladder failed her.

Lyra felt the fluid trickle, she hadn’t peed herself since she was a teensy, tiny small filly. When the bathroom seemed so far, and she was busy. Humans also didn’t seem to pee themselves too much, though she had discovered about this thing called incontinency. Not a pleasant thing.

She didn’t feel the liquid trickle down her legs however, and it just warmed up the diaper. In fact it made it seem somewhat swollen, providing a thicker bottom. She was surprised to see it all get absorbed, not at all wet.

A single, devious thought came to Lyra’s mind…

“You need to change me.”

“What? You’re an unicorn, surely you can pull the straps with your magic!”, Bon Bon had accepted many things about her best friend, but this was a whole new thing.

Tears formed in Lyra’s eyes, as she was a very good actor “But Bon Bon, nopony should be changing their own diaper…” she said with a sniff “Besides, I’ll change yours when you use it.”

“I will NOT wear one of theses… things, let alone use it.” The disgust in Bon Bon’s voice was more then clear.

She wasn’t going for it. Lyra cranked up the waterworks, trying to get her to at least change her once, she couldn’t let this opportunity go to waste. “But Bon Bon… I LOVE YOU!!!” Lyra started the howl out like a little foal, she was serious about getting Bon Bon to change her!

“What that got to do with anything?! I ain’t changing you! And like if it wasn’t bad enough you’re dressed as a foal you have to act like one now? For Celestia sake, just get up already!”

Bon Bon’s muzzle had that clear line that announced danger. It was a sign to thread clear, one that had stopped monsters from escaping Tartarus. But Lyra wasn’t deterred.

A thought came through Lyra’s head, nay, a stroke of genius! “But Bon Bon… “ Lyra said between cries and sniffs. “How are we going to have little foals of our own without practice? You clearly must train with me!”

“Foals? Lyra we just started going steady 8 moons ago! We haven’t even started talking on getting married and you talking on foals?” Bon Bon was at the age of her nerves at this point before it hit her. “Lyra, you and your paper thin excuses, I ain’t changing you and that’s final!”

“Worth a try, the concept of moons is flexible anyway”, Lyra shook her forelocks, as if that could give her the reason she so desired. In fact, she decided, she could get into this. Her begging and whimpering for Bon Bon to act, and Bon Bon refusing, delaying the pleasure until a certain point. She acting like a foal, acting up and demanding, nay, deserving of a change. It was just what she desired. Oh to have Bon Bon do that for her.

The desire in her belly grew, it was a clear need. It was as if her entire frame needed to be changed. Not because she was wet - the diaper held, but because it was something quite close she could do with Bon Bon. This was a whole new level of depravity, and closeness. This was what mother did to their foals. To think that she’d hold Bon Bon in such close regard - and to think she’d be within sniffing distance of her urine...It just brought a blood to her cheeks. Yes, Lyra was blushing over the idea of her Marefriend changing her wet diaper. While it wasn’t a place she assumed she would end up in just mere moments ago, it is a place she ended up in, and she loved every bit of it. If only she had a way to make it happen, some sort of bragening chip… “I’ll do the dishes for a whole moon if you change me.” Lyra kinda hoped this last ditch effort would fail, as she was notorious in the lengths she would go to avoid such a chore, but if it meant that Bon Bon would change her wet diaper, it would be worth it.

“No w… Wait. you said a whole moon?” Bon Bon blinked a few times at the offer given to her before she started to consider said offer. “You, doing the dishes, let alone for a whole moon? That is something I need to see, deal!” Bon Bon approached her friend who was already lying on her back before a question came across her mind “You only have the one diaper… right?”

“Well…” Lyra cheeks got even brighter. “The least I could get was 2… So I bought 80 of them…” A small glimmer of light appeared as Lyra opened her closet door to reveal a whole stack of these foalish clothes.

“Lyra…”

“Oh give me a break, they were discounted... if bought in bulk”

A hoof flew from the ground to Bon Bon’s face. How could she handle this? Lyra was weird, obnoxious, obscure with her references. And she didn’t understand the concept of a bargain. She had ended up spending more on diapers she would never use than if she had bought the two.

A sinking suspicion came to Bon Bon’s mind.

“This isn’t going to become a routine for you, like your nightly 3am lyra practices, is it?”

Lyra scowled. “The lyra practice are an improvement from the 4am bongo practice…”

The hoof resonated again against her face. Lyra was either being silly on purpose and missing the point, or just straight up didn’t get it.

“And it did get me that birthday party job, where I played the legend of epona tunes for Button Mash, - kind of weird to make a party centered on video games but…”

“Still more normal than this, get on the bed so I can change you.”

“Won't you use the changing mat I got?”

Bon Bon’s eye twitched more than she thought was possible “you got… A changing mat? You bucking kidding me?!”

Lyra blushes“Well It was included with the 80 diapers… plus the adult onesie, bib, foal bottle, adult pacifier and mittens, it was a weird shop…”

“And who was ponying up the shop?”

“I think it was Pinkie Pie, I couldn't tell, they never took off their sunglasses, hat or fake mustache, but they were pink with curly pink mane. They were pretty crazy, kept saying something about 'it will make for an awesome story’, so Pinkie Pie or Screw Loose. As I said, it was weird but you know I can't say no to a bargain!”

Bon Bon groans loudly. “Fine where is that changing mat?” She won’t fight it anymore, Lyra is Lyra and when Pinkie is involved it’s best to just not over think about it. Pinkie is almost as random as Discord. She’d almost prefer to be dealing with all the monsters, she, as special agent Sweetie Drops had to deal with all over again, at least she’d know what to expect.

A soft blue glow is seen as Lyra uses her magic, and an object comes flying in from under the bed. It’s a changing mat, Bon Bon recognises it as her eye twitches.

“Here we go, now I’ve got some bags in my bed stand..”

Bon Bon push Lyra towards the bed “Yeah yeah, let’s get this over with it”

“You sure you…” Lyra started saying but she’s cut short

Any further conversation was interrupted by the fact that Bon Bon had her mouth very close to Lyra’s rear. She held her breath, she could practically feel the hot air of Bon Bon’s respiration on her tail, which flicked in response. She seemed to hesitate and with every second, Lyra’s arousal grew. She wanted it, she needed it. It was very similar to a spell that her former classmate, Twilight had once cast. It looked as if she were going to blow up in anticipation. In fact she’d blow up twice.

And then with a tug, the first touch. Lyra had the naughty thought that, being an earth pony, Bon Bon had no choice but to use her mouth. She had quite a dexterous tongue. She had previously used it to please Lyra, as she had previously used it to untie knots. Bon Bon lived a pretty extraordinary and weird life, even for Ponyville standards.

But then, Bon Bon didn’t think that she had ever done something quite as weird as this.

It wasn’t as if it tasted bad, or it felt unpleasant. She only tasted cloth, and most of the smell was diminished by its dampness. She wasn’t sticking it up on the inside, instead tucking at the bands. Bon Bon was an older sister she had done this before. She just never thought she’d be doing it quite so intimately. She found herself blowing a raspberry near Lyra’s belly button, noticing the erect nipples.

Is she, is she getting aroused by all of this? The thought was a pleasant one, as Bon Bon aimed to please. With a particular strong tug that gave her a whiff of the smell of pee, she pushed it out.

“Alright, it’s out, we’re done here”

Lyra held a sheepish grin as she pointed at the closet, Bon Bon was afraid to ask as she approached, trying to figure out what it was she wanted. She noticed the foal powder after a few seconds of glance. Seriously?

“Please Mommy Bon Bon, put in me another diapee…” Lyra begs, seemingly all inklings of research forgotten, it seems she’s gotten into this.

Bon Bon groan, but she can’t quit now. Lyra will use any excuse she can do excuse herself from doing the dishes “Sure thing, Mommy will put you in a new one.” Best to play along for now, it will get things done faster.

The smell of baby powder was not an unpleasant one, though Bon Bon’s narines flared more due to the proximity to her “best friend”, arousal than the smell of the powder. She holds the bottle in her mouth and everytime she pushes a few drops she gets closer to that wonderful smell. Lyra’s hole glistens in the light, sleek with her juices as well as urine. Bon Bon doesn’t much care for the pee, but at least the baby powder is sticking to it and dampening the smell.

There’s something about the smell of baby powder that is comforting. Maybe it’s the way it seems to pacify Lyra, who stops kicking her legs. Bon Bon always told her she acted like an overexcited foal, so maybe this is just the natural conclusion to that.

Lyra trembles and winks like she never did before. Bon Bon doesn’t know if she should attribute that to the clearly mind blowing orgasm Lyra had, or just the discovery of a new fetish. A new taboo. Using a hoof to spread the baby powder she can’t help but rub it amongst her lips, feeling the opening. Bon Bon has to admit, despite this not being her cup of tea at all, there’s something about having Lyra so completely lost and dependant on her, trembling, begging, and wishing for release. It makes her feel Good.

As she grabs another diaper she half laments covering up that appealing opening, those lips she so desires. Holding the diaper in her hoof she pushes her tongue forward, moving from her nipples, which she gently nibbles on, to her belly button, which sticks out in the rounded belly. She moves her tongue, carefully, gently, savoring the moment, and Lyra still trembles.

At last she pushes it to her lower lips. She expected to give it a tongue lashing that would make her feel even better, but Bon Bon gets a nasty surprise. She hadn’t counted on the urine, and were she honest the strong flavor would the experience more memorable, but she hadn’t counted on the powder. It tastes nasty, she gags and Lyra laughs.

Grabbing the diaper with her mouth and using some of her Earth pony strength, and training from being Sweetie drops, she lifts the entirety of Lyra’s lower legs. The view is enticing, and despite the taste of baby powder in her mouth she half wants to go for it, but she controls herself. Plenty of time for that.

She pushes the diaper, careful to push the tail through the hole. Lyra’s clear fluids threaten to overflow the baby powder, so she throws a little bit more for good measure. She holds Lyra’s legs. Not an easy task, when they’re shaking in what is clearly a fit of desire. At last she struggles with the strips. They’re harder to pull and close than she realised, but finally it’s done.

There she stands, Lyra. In a diaper that covers the entirety of her lower rump. It’s an obscene sight, a sight that one wouldn’t expect to see between adult ponies. But it’s one that Bon Bon clearly enjoys, not to mention Lyra’s excitement. Bon Bon’s face is covered in sweat, and the back of her throat doesn’t exactly feel nice. While her tongue would normally savor the taste of her best friend’s arousal, now it tastes a combination of three elements. Even the taste of urine doesn’t bother her as much as the powder did.

Her mane is a mess, but she only has to stare at Lyra’s big, puppy eyes, and her dopey grin, to smile. Despite all that, that wasn’t so bad. She might consider doing it again some other time.

Bon Bon puts a hoof to Lyra’s belly, who giggles.

“Stop being a foal, you’ve got chores to do.”

Lyra grimaces.

“But Mooooom!!”

Bon Bon eye twitches. Now that they have taken this step into Lyra’s, no other word to call it, fetish, is there no way out?

“I can’t believe I offered to do the dishes for a moon, that’s a whole fifteen days”, she murmured.

“Not what a Moon is!”

“Don’t care!”

“Well you’d better care, you’re not inching your way from this one with such excuses as I don’t own a calendar”

“Ponyfeathers…”
