On the circle of raised sand where a paopu tree bears star-shaped fruit two people sit on a blanket, watching the setting sun dip beneath the waves of their world’s ocean. The small basket of food brought with them is mostly gone, it has been for a while. The point of coming out here wasn’t to eat but to chase memories of the past.
“Seems almost silly to do this now,” Sora says, kicking his feet out from the ledge of the small plateau, “we’re adults after all.”
Next to him Kairi giggles. She’s sitting with her legs off to her right side, pressed tightly together while she supports herself with her left hand.
In a lot of ways, the man next to her is right. Their voices are deeper, their bodies matured, and they’ve even arrived at the magical age of 21 where everybody they once considered to be “adults” calls them grown but they didn’t fully feel it. Sora, despite his more serious attitude and deeper voice, kept his competitiveness and playful wonder from his youth. She reflects about herself and, in the least self-centered way possible, decides she still holds onto the caring attitude and values she had all those years ago when the heartless appeared and their journey through the worlds kicked off.
There are other things too—things she knows go beyond being friends. The shared feelings between the two haven’t been expressed yet, both hesitating yet wanting things to change.
Without warning she swings her legs out, bringing the bare flesh of her calves and thighs before Sora in an enticing manner, at least she thinks so anyway. She can see Sora watching, curious as to what she’ll do next. Kairi doesn’t want to disappoint.
Her legs drop over the side of the ledge, almost next to Sora’s. Kairi spreads them wide, her thighs lift up her skirt as they distance themselves from one another and reveal the yellow-stained crotch more and more as she goes.
As she continues to spread her legs more, the visibility of her diaper increases. First it's just the stained white padding, then the fading red lines, hearts, and stars up above it and finally the core that covers Kairi’s waist is shown with the little curled heart symbol that decorates the landing strip. Sora can’t peel his eyes away or stop himself from going bright red. Kairi begins to wonder if the next words will even reach him.
“Yes, what big adults we are to have to be padded all the time.” she says coyly.
Sora struggles to reply, but it only comes out as a bumbling stutter that leads to nothing. Rather than waiting Kairi jumps up, stepping away from the blanket while fixing her skirt.
“Where are you going?” Sora manages to say, looking longingly at Kairi as she steps away.
She gives another giggle and jumps from the platform that at one point seemed so tall to her. “You’ll have to catch me to find out!” she calls back, taking off down the shore.
Sora doesn’t move, nor does he think he can at that moment. The front of his pants is tenting outward, the sight of Kairi’s diaper having aroused him enough to bring out a full-on erection. With each little rush of blood that causes a stiffening in his dick something underneath Sora’s pants crinkles a little, betraying the fact that both he and Kairi are wearing very similar underwear.
All he can do is watch as Kairi puts more and more distance between herself and him. The hem of her skirt jumps as her legs hit it, giving Sora the faintest peek at the soaked padding underneath. His breath hitches in his throat.
There’s a wild and desperate want to chase after her, to run her down and share all his overflowing feelings with her, but he doesn’t. Instead, he sits and waits, letting the harsh stiffness pressing against the spongy, moist material of his diaper die down slowly.
He loves diapers and knows that Kairi loves them too, but in Sora’s mind that’s always been a private thing, something he’s never been inclined to share. He only now understands that Kairi may want to bring it into their passion play but there’s no certainty. Something in him wonders if he should make the first move. Is he ready for that? Is she?

While a rare moment of overthinking takes over Sora, Kairi pumps her legs across the golden sand of the beach. The warm air blows against her and makes the frantic teasing run all the more difficult. Still she dare not stop, because behind her she can feel the vibrations in the sand. The sound of Sora’s oversized shoes as they slap against the sand behind her at a steady pace—she swears it's there. In fact, it’s the only thing she focuses on.
The lapping of the waves, the hot sun, and even where Kairi is going fall away to the anticipation of the moment. “He’ll catch me,” she thinks, “he’ll catch my arm and spin me around and we’ll lock lips. Then I can rub the front of his diaper like I wanted to and he can feel mine. We’ll fall onto the sand and just…”
Kairi lets out a gasp for breath. The run has her winded and her thoughts are bringing up a rising heat like she cannot believe. The anticipation is too much and despite her wanting to be caught by her spiky-haired love she stops, curious to see what's taking so long.
When she turns around to see that Sora isn’t in fact behind her, or even anywhere in sight Kairi frowns. “Did he even try?” she huffed to herself.
The realization of how far she herself has gone only now hits her. Kairi doesn’t recognize this part of the beach and she never remembered a craggy outcropping of rocky walls like this here before.
The cliff face before her rises sharply and looms high above Kairi, its face lit by the glowing orange of the setting sun which is slowly dipping behind the horizon. Other than the fact that Kairi had never seen the landmark before, one other thing catches her eye, something she feels strangely drawn to.
About twenty feet in front of her, cut into the face of the rock is a hole. The edges of this hole are cleanly hewn with an almost unnatural feeling to them when compared to the rest of the untamed environment around them. It’s not these clean cuts that make the cave mouth look like an almost perfect semi-circle that pulls Kairi towards it though, it’s the glow emanating from the otherwise black interior, a soft blue that pulsates invitingly.
Like she’s caught in a trance Kairi moves toward the cave, forgetting all about her previous frustration as she moves. “I’m sure Sora will catch up,” she thinks, “he always does.”
Given her past of fighting heartless and nobodies Kairi figured she ought to be more cautious but it wasn’t as if she was walking in unarmed. Her Destiny’s Embrace could be summoned within a second.
The interior of the cave wasn’t even as dark as it appeared from the outside. The orange of the sky bleeds through a hole in the ceiling and melts together with a soft blue glow that emits from clusters of bioluminescent mushrooms that grow from crags in the rocks every couple of feet. It gave the cave a soft purple tint to its atmosphere and stole Kairi’s breath as she stood dumbfounded at the sight.
“It’s beautiful,” she exclaims, stepping forward while staring at the glowing plants on the walls. She wonders how long this place has been here and cursed herself a little for missing out on it after all this time. It would have been amazing to find back when they explored as kids.
Kairi gawks and walks, failing to pay attention to the ground in front of her as she moves. Only when the sound of her footsteps transform from soft taps of rubber soles on rough stone to a loud squelch does she snap back to reality.
Kairi notes the new consistency beneath her feet with a restrained disgust. She’s stepped in something, by the feel of it something sticky and viscous. A glance down reveals a puddle that seems to spread out across the entirety of the cave floor leading deeper into the purple-tinted wonderland.
It’s hard to tell with all the conflicting colors but when Kairi pulls up her foot from the puddle she can somewhat discern that the strands of slime are a translucent yellow. The redhead tugs her foot away from the pool, only to find it has a better hold on her heavy black boot than she’d originally thought. It coats the bottom almost completely and threatens to tug the rest of her back into the reservoir of goo with its surprising elasticity.
“H-Hey let go!” Kairi says indignantly, pulling with all her might to free the boot trapped in the slime.
To her surprise somewhere within the cave a soft, feminine voice responds.
“No.”
3
Kairi’s eyes fly open wide. The possibility that she wasn’t alone hadn’t even occurred to her, but before she could discern where the voice was even coming from the strands of slime connected to her foot snap back into the puddle suddenly, tripping all of Kairi’s weight forward in the process.
She lets out a startled cry as she starts tumbling forward face first into the goo. In an effort to protect her hands and face from splashing into the liquid—let alone the rocky ground underneath. Kairi attempts a pirouette on her pointed toes, finding the material much more malleable than she originally thought. It turns with her, allowing her back to splash against the puddle rather than her face.
The impact is much softer than Kairi expects it to be. As her body collapses into the gelatinous yellow puddle it cushions her, lifting her up and away from the hard stone ground of the cave below.
The dust settles and Kairi is breathing heavily for the second time today, feeling wiped out between the run on the beach and the exciting tumble in the cave. She takes a quiet moment to examine her predicament.
She’s landed with her arms outstretched at her sides and her palms flat in the slimy goo. Her legs are similarly splayed out, with her skirt lifted just enough to expose the crotch of her diaper. The fall caused a splash, allowing strands of the substance to jump up and around her body.
A gentle tugging at her limbs proves that they’re stuck fast. Each shifting pull of her limbs brings the slime up with it before it snaps back down like rubber. It’s stretchy in a way allowing Kairi to move a little before she’s pulled back to her default position, the one she fell into.
The redhead sighs, wondering how long she might be stuck. Sora must have surely been right behind her on the beach and would probably come to save her soon enough. That’s when she starts moving, despite being stuck to the bed of slime around her.
Kairi looks around in surprise as the puddle shifts, dragging itself along the cave floor like a slug slowly. She lets out a yelp, redoubling her efforts to pull away from the sludge once again as it drags her deeper into the geological formation, away from the orange glow of the cave mouth and the freedom of the outside.
“No, wait, stop!” she shouts, thrashing against her semi-liquid bonds as they move, “Let me go!”
Her repeated plea for release actively slows the movement of the opaque yellow goo but does not fully stop it. Again the voice permeates the cave, reminding Kairi that she is not alone. “Let you go? The fun is just beginning though.”
Next to Kairi’s leg, the slime starts to shift, piling up on itself. The rising mound of slime takes shape as it grows, bottlenecking from a wide bottom up into another bulbous top. The shape of breasts is unmistakable in the form, that plus the feminine hourglass shape causes Kairi to blush. Whatever this thing is it’s trying to emulate the female form and show off while it does so.
The arms and shoulders stack on top of that and finally a head topped with dripping rivulets of slime that hang from the head like hair. The slime’s facsimile of hair would have been shorter, shoulder length with a part running up the left side and leaving two bobs on the side of her head if it were real. Colorations in the slime's surface form the facial details on the thing, with it giving a coy, half-lidded look down at Kairi, much like the one she’d given Sora on the beach.
“Hello!” the creature says.
Despite the kind and inviting tone of the thing Kairi is unable to respond and sits flabbergasted with her mouth agawk.
“What’s wrong Kairi? Nothing to say, or is it just that you’re too turned on right now?”
Again another shocking revelation, two even. One this thing knew her name and seemed to regard Kairi almost like she was an old friend rather than a kidnap victim. Two it had called out—accurately—that Kairi was feeling a certain arousal from the situation.
Something about the slime gracing her skin sent a tingling through it giving rise to a myriad of goosebumps up her arms and legs. It was sticky and firm while also providing the sloshy squelch of something liquid. She struggles to place why it made her shiver with each little jolt of stimulating electricity, then it hits her. The slime reminds her so much of a wet diaper. It’s like being wrapped in one without any of the grossness.
The slime pinning her down nods approvingly, almost as if it can see the gears working in Kairi’s head.
“You’re starting to get it aren’t you? I’ve been watching you and your cute boyfriend get together all day and nothing, but here you are just enjoying the touch of my slime. Why do you think Sora is hesitant, Kairi?”
So much was happening all at once, and the question the creature asked brought up far more questions to Kairi. Rather than rapidly firing them at the creature like she wants to, Kairi focuses on one, hoping that it will clear up all of them. “Who are you?”
The slime creature reels in mock shock. “What? You don’t know me?” Her demeanor changes back quickly though, back to the sly smile and half-lidded eyes that tell Kairi very little. Her words however are happy to grace Kairi with whatever she wants to know. “I’m Saranya, a slime succubus from another world, trapped here after a random portal dropped me off.”
There was a lot to parse out of that sentence though Kairi wasn’t given much of a chance to. While she lay helpless the hands of the succubus who’d identified herself as Saranya the creature herself ran her hands above Kairi’s body, orchestrating the bed of goo beneath her to bring strands of itself creeping up Kairi’s body.
She could feel them slipping along the exterior of her clothes, connecting to the other side, and sending more tingles all throughout her body. To her surprise it wasn’t just an internal feeling, her clothes fizzled against her with each strand of slime that started to hold her down and cocoon her.
The bubbling carbonation danced across her skin as it ate away at her garments, causing them to disappear around her body. “W-Wait, is that going to hurt me?!” Kairi asks in a panic. Saranya raises her hands in denial. “Of course not.” she says, “I just thought you’d prefer to be a little more comfortable for when Sora finds us is all.”
True to her word, the strands of slime come to rest on her as her dress disappears but no burning sensation follows, only the stickiness that tugs at her skin slightly and the residual moistness left over by the goo.
Kairi is held down by the stickiness of the bed beneath her along with bindings made of the same material. They’ve looped up and pulled tight now that her dress was out of the way. Only the leftover tingle of the fabric dissolving remained for Kairi who was left now only in her diaper and bra. A lot of strands from the slime also cover her but given its translucent nature she cannot rely on that for modesty.
She wants to throw her hands up to cover herself, but twenty ropes of binding goo keep each of them held down more than before. What little slack she’d had is now gone.
“What is the point of this?” she asks, gesturing down with her head to her exposed torso and diaper.
Saranya shrugs, “I figured you’d want to be more comfortable before Sora arrives. More importantly, what’s the point of this?” Her hand reaches down, pressing into the soggy crotch of Kairi’s diaper.
The material squelches and groans from the external pressure of the succubi’s touch, mashing against Kairi’s body and eliciting a moan from nowhere. She can’t stop herself, the excitement is starting to overtake her worry.
Saranya is still waiting for her answer, Kairi can see it in her eyes but she doesn’t remove her hand.
“I-I just like diapers so I wear them. Is that a big deal?” Kairi asks, getting a little indignant.
She gets a chuckle in return. “Not at all, but do you just enjoy them or is it something… more?” Again the succubus pushes its hand into the diaper, eliciting a full-blown moan from its trapped prey.
The succubus laughs. That's all the answer she needs from her to see if she’ll continue. “I’ll bet you’d love to feel something like never before, something only I can offer you don’t you?”
Kairi turns her eyes up to Saranya. They’re filled with a mix of lust and wonder, like she can’t wait for the creature’s next words.
“Do you want Mama Saranya to make you feel good?”
Kairi blushes and nods only giving a weak whisper. “Yes.” she says.
“Good, then the real fun can begin.”

Saranya waves her translucent hands over the puddle of slime again but instead of even more strings of the goo lashing down Kairi's body to the bed of slime, it forms into hard ovular beads, five of them to be exact. They move fast, sliding up Kairi’s body and gathering in a little star shape.
She stares at them for a second, waiting to see what the succubus has in store for her. The beads of hardened, built-up slime then start to buzz, vibrating rapidly on Kairi’s abdomen like little bullet vibes but faster. There’s not a build up, just an explosive pulsation emitting from each one.
“Let’s start off small shall we?” Saranya says locking eyes with Kairi.
“Wha—”
The redhead’s exclamation didn’t even get off the ground before the little vibrating pills of slime shoot toward her sensitive bits. Little burrowing movements come from the ones attempting to slip beneath the fabric of her bra, trailing their vibrations along her skin until they find purchase on her nipples. Much like the bed of slime below, little strings of material held the vibrating beads in place.
Another two land underneath the waistband of her diaper, sending waves of kinetic energy through her hip bones. The last hits a sensitive point that Kairi wasn’t prepared for, sitting right above her clit hood, adding pressure to the sensitive nub through her protective lips.
Time froze for a moment, giving her the chance to take a deep breath in between the synchronized pulsating of the little yellow beads. Kairi absorbs the entirety of the scene around her in that brief freeze. The bed of slime she’s been lashed to, the bulge of her very soggy diaper that’s squished up by the mountain of slime, her mostly naked form—left exposed due to her melted clothes, and the slime succubus staring at her eagerly. All of it feels overwhelmingly erotic as she absorbed the scene, like if she’d watched it play out she’d give a little bite of her lip from the slight animalistic desire it flooded her with.
Such a passing thought is quickly dashed though, time resumes for Kairi and so too does the vibration of the organic bullet vibes at their sensitive points all over Kairi’s body.
If the slime caused her body to tingle a little before now she was jolted, a live wire charged with sexual electricity and thrashing wildly. She pulls against her slimy bonds, feeling them follow as her back arched and her head is thrown back in excessive, erratic pleasure.
There’s that slight twinge in her bladder along with all the other sensations too, a slight need and urge to pee. If Kairi wasn’t currently wracked with the most intense pleasure she’d ever felt, she’d just let it out and enjoy the squishy reward of her own padding privately, using a stuffed animal or a couch’s arm to hump it against. Now however the little bullets on her hips are vibrating everything loose in her abdomen, shaking her nearly full bladder aggressively and causing it to spas. Rather than just peeing herself Kairi lets out a wild spray of hot piss into the squelchy padding that’s already soaked from the day’s accidents as she cums due to the treatment.
Without meaning to, Kairi howls, filling the space of the cave with her call while she feels the charge of an orgasm that’s unlike anything she’s ever felt before. The vibrations of the little slime bullets work quickly, sending Kairi into a spiral within moments. They don’t let up either, the meticulous pulsating continues on Kairi’s erogenous zones.
She can, at this point, hardly tell where one orgasm begins and another ends, sending her into a state of consistent thrashing and howling. Around her waist the Keyblade Kuddler diaper continues to swell, its thick core becoming more piss soaked by the second. Kairi didn’t even thing herself capable of holding so much pee, then again this could have been several seconds for her or multiple hours. Time had no meaning in the endless ring of buzzy pleasure.
Saranya watches above her with elated glee, both enjoying the show and the stream of sexual energy from her victim. Kairi cumming fills her with more power every passing second. She notices too the swell of the girl’s diaper, its bottom even more rounded than when she entered the cave and the little lines and stars having mostly faded away by now.
She wonders briefly how it hasn’t come to the point of leaking or bursting When she focuses on it for a moment she gets a surprising answer. The diaper itself is imbued with magic, and lots of it. Saranya can read it like a book now that she knows she sees how each charm tailors the experience of being diapered to Kairi’s tastes exactly.
“Oh,” the succubus exclaims, “You really must love wetting yourself if you’ve put so much effort into enchanting these diapers that much. How many times did you use this today I wonder? How many more times can I get you to go?”
Kairi only half hears the succubi’s taunts at the edge of her consciousness, the pleasure of the vibes is making it too hard to focus.
Saranya directs her slime gleefully, using some of her newly acquired energy to morph the goo to her needs. “It’s worth it in the end,” she thinks, “I practically have an endless generator right here.”
From her bed of slime, a small tube offshoot slithers through the cave, poking itself eventually into a freshwater spring hidden deeper inside the geological formation. The other end comes up to Kairi’s mouth, waiting for her to open and accept it.
Even though glassy, half-attentive eyes the redhead seems reluctant, and gives a little shake of her head. Saranya sighs and tuts at the captive battery in the form of a perpetually cumming diaper girl. “It’s okay baby girl, Mommy Saranya just wants to make sure you’re not going to get dehydrated…”
Kairi still refuses, keeping her teeth clenched tight. An idea pops into the Slime Succubi’s head, a little more energy and she has a bulb at the end of one of her arms rather than a fist and instead of the unappetizing end of a slime-made tube, a translucent yellow pacifier waits for Kairi.
The redhead is confused but while she’s focusing on the dummy floating patiently above her head and the buzzy sensation of the bullet vibes she neglects to see Saranya’s arm begin to vibrate as well. She has no idea it's heading straight for the soggy, bulging crotch of her diaper.
When the rounded head of the vibrating appendage makes contact with Kairi’s nappy it sends shockwaves through the entire plastic shell. Her whole diaper rustles and squelches, shaking all around her waist and groin as the mushy core is compressed closer to her. It rustles loudly, pulsating all over and adding to the shocks of pleasure.
Kairi gasps, unable to believe this thing’s capabilities, it comes closer and closer to her. Compared to it the bullet vibes were weak, and even without direct contact, she’s taken to a whole new dimension of sensation. With her mouth left open due to the shock of the wand-like appendage, the pacifier-tipped tentacle sees its chance and lunges for Kairi’s mouth, filling the space quickly.
She finds the feel of it to be more rubbery than she’d expected, with the nipple of the dummy depressing her tongue due to its sheer size. A steady stream of water quickly follows the pseudo-pacifier filling her mouth and trickling down Kairi’s throat slowly.
The bulb of the vibrator finally makes contact through the soggy diaper at the same time, with its jackhammering pulse transferring through the still hot, squishy piss-soaked core of the diaper directly to Kairi’s most sensitive areas.
White lightning fills the space behind her eyes, another intense orgasm wracks her and she pees again, expending the water dripping through the pacifier feeding tube in her mouth quickly. Saranya weaves little spells above her using the energy generated from her toy, making sure she won’t get tired, speeding along the body’s processes to make her bladder fill again and again, and toying with the timing of the vibrations, giving her plenty of variation in the intensity so she isn’t bored.
For a brief time, Kairi becomes a constantly cumming water fixture, taking in water only to add to the mass of her diaper and increase its area further with her own piss, all while feeding the playful succubus her sexual energy.
And then, like a hero from a story book at the mouth of the cave the pair hear a call.
“Hey!” Sora says, “Let her go!”
5
The spiky-haired keyblade master stood with his weapon already summoned.
Saranya doesn’t react much to the intruder but, below her, Kairi hears the succubus say something like “Ahh, right on time.” before directing her spare hand out toward him.
Sora doesn’t do much to evaluate the scene, understanding that Kairi is being held down while thrashing about and that some inhuman creature is responsible but most of the details in the low light glow of the cave. The sun is already almost all the way gone behind him and his eyes haven’t yet adjusted.
Without taking full stock of the situation he rushes forward, lunging into the cave blindly with his keyblade at the ready. His feet trample into the puddle indiscriminately, and he swings at the first stack of yellow slime he sees in front of him.
When the blade comes to a screeching halt, connecting but not following through in the way he expects, Sora stops and takes stock. He sees the slime woman next to him, one hand pressed against Kairi’s padding and the other waving at him.
The woman he loves is thrashing in the bed of slime below her, lost not in panic but in rapturous agony, a spine-tingling pleasure that has her curling her toes.
What Sora has hit with his keyblade is exactly what he’d seen while carelessly running up, a stack of slime in the crude shape of the creature he’d been aiming for. “Whoops,” Saranya taunted, “looks like you missed.”
Without even a chance to try and free his weapon the slime dummy he struck explodes in a brilliant blossom of viscous yellow liquid that easily dwarfs Sora in height. For a brief second, it even resembles a flower before turning into a tidal wave of goo and washing over him.
The strength with which it crashes into him is immense and knocks him out of his comically large sneakers and down into the bed of slime next to the squirming Kairi. That same wave makes quick work of his clothing, eating away at it much like it had his girlfriend’s and leaving the same tingle running across his now bare skin.
Only his own diaper remains intact, swollen with its own collection of urine from his day's worth of accidents. The same design of stars and lines has faded significantly but some of the little blue lines are still visible through the plastic shell on its stained core. Saranya watches the young man go through the motions of struggling against the slime but he gives up quicker than Kairi, mostly because he’s quickly distracted by her erotic display of spasming orgasms and diaper filling.
The crotch of the redhead’s diaper distended and bulged to a point near below her knees, so swollen now with piss that the continuously absorbent core had to expand greatly to contain her accidents.
The sight is enough for Sora to become extremely aroused himself, tenting the front of his padding with another raging erection. Unlike the one he’d had at the beach, there was no hiding it here. His baggy pants were gone and he was laid flat on his back.
Kairi was tangentially aware of all these events as they were happening but only when Saranya stopped did she fully re-engage with reality. The little vibrating bullets also stopped and melted back to the pool below and the feeding pacifier retreated back from Kairi’s suckling mouth into the pool. She is left panting while locking eyes with Sora.
“G-Gah! Wh-Wh-what happened?” Kairi asks, “Did she get you too?”
Sora blushes, nodding. “I hit a double, probably should have been paying attention.” He punctuates the statement with a little chuckle trying to lighten the situation.
Saranya chuckles next to them. “If you aren’t you two just the cutest two lovely diaper lovers. So soggy and horny~!”
At this the pair blush, not saying anything and avoiding eye contact.
“Wouldn’t you just love to come together? To feel each other?”
Sora speaks up semi-indignantly, shaking his head. “Not with you here! Not with a bed of slime holding us down.”
Next to him, Kairi spoke softly, “Not that we ever have anyway…”
The mood shifts suddenly with all three going quiet. The succubus looks shocked while Sora shows a look of disbelief at the comment as Kairi pouts sullenly.
Saranya was the one to finally break the silence. “You two have never ‘done it’ in your diapers? Really? I figured with all that very pervy magic throughout your padding that’s exactly what they were for.”
Sora blushes an even deeper red, trying to avoid the question. “I-I just thought it was its own thing, something we just did privately. I didn’t know you wanted to do…that.”
A different look spreads across Kairi’s face, a realization that she hasn’t vocalized exactly what she wanted before, that rather than just having sex or playing around in diapers that she’d like to try both, to have Sora fill her while she’s diapered.
“I-I do,” Kairi says nervously, “and I think… I want to do it like this. I kind of like Mommy Saranya’s slime holding me down.”
The slime succubus smiles at the use of her name like that, happy to oblige the pair in whatever they desired. “If you’re willing, I’m happy to just sit back and provide a little help. Your energy would be a wonderful boon to me.”
Whatever hesitance remained in Sora quickly dissipated with his partner’s confession of her needs. “I understand,” he says, “let’s do it.”
6
As if she can read their minds Saranya loosens the bonds around Sora, allowing the strands of slime to shift and move with him as he rolls himself over to Kairi, placing himself above her and face to face. His lower half is limp, with his diaper’s crotch pressing into the swollen protrusion of hers. He’s holding himself up above her with straight arms and a gentle look in his eyes.
The slime holding down Kairi’s arms loosens too, giving her the freedom to run her hands across Sora’s bare chest, feeling the muscles beneath his smooth skin. Even through multiple layers of thick padding, Kairi can feel the slight prod of his erection, aching to get through to her and make contact.
“Are you sure this is what you want?” he asks softly to her.
With a resolute assurance, Kairi says “Yes.” She follows with a concerned “Is it what you want?”
Sora lets out a deep sigh, closing his eyes and untensing his shoulders. “Yes, it is, without a doubt. I just didn’t think you did, now that I know, so no more hesitating.”
“Kairi smiles. “Then come on.” she says.
Within the pair’s diapers a spark of magic ignites, and the heart logo beneath the landing strips glows on each diaper. Inside the squishy interior of each set of padding a portal opened, a whirling hole that connected the diapers to each other. Sora is allowed his erect member through the magical openings that connect the two diapers. His girth was no longer imprisoned against his body and the soaked padding in his own diaper but now penetrates the heat of Kairi’s diaper and its head comes to rest against her slick opening.
To get a better angle he brings his knees up, granting him a little more leverage, but also mashing the front of his diaper against Kairi’s. She let out a gasp, feeling his member push in between her lips gently as he shifted. With his position solidified Sora rested there for a moment, with just the tip enveloped in the folds of his lover.
Kairi brought her legs up around his hips, resting her heels on the back of his diapered butt.
Saranya helps by shifting the slime in the bed, ringing her binds up to tie the pair together at the torso and cementing their legs in place. As long as she wished it they’d hold this position with each other in a tight sexual embrace.
Kairi bounces on her hips a little, urging Sora to move. “Please…” she whispers.
In response Sora eases himself in, sliding the length of his cock into Kairi, who moans in delight. The squishy core of the diaper compresses around each of their pelvic areas with the thrust, adding an extra degree of diapered enjoyment to the situation.
Sora withdraws and re-enters, keeping a slow and steady tempo to his movements so as to build momentum. He’s surrounded by both the slick heat of Kairi’s pussy and the soaked core of the diaper and it sends jolts of sensation up through his pelvis and up his spine, filling the space behind his eyes with starbursts of white light.
Kairi herself followed the pace with her own hips, bucking against her lover and relishing every stroke that pushed along her inner walls. The flared mushroom head of Sora’s dick would just barely separate, brushing her labia’s lips before he pushed back in, his cock plunging its way through to her womb.
When fully inside her she could feel the squishy padding smothering her pussy and rubbing against her engorged clit. That brush of soggy fabric against the thousands of nerve endings in her pleasure button sent waves through her, a crashing tide of exhilaration that she wished would never stop.
And then Sora would retract his cock again only to push in again, a torturous cycle that she was in love with. Pleasure and sensations were mounting in the two, with building feelings threatening to overcome them. As such their pace increased. What had been slow deliberate strokes became a more furious pumping. The rustle of their diapers smooshing together did little to hide the wet sounds of sex inside let alone the soaked cores compressing and settling over and over again.
With a howl and a holler Sora thrust hard, pushing as deep as he could into Kairi, she responded in kind with a yell of “YES!”
Sora’s cock twitched and exploded inside of her, pumping spurts of cum into his lover’s pussy as it contracted around him with its own reactions to orgasm. Kairi was milking him dry with her vagina, bringing out all the release she could from him and she loved it.
This was different from the intense marathon of the vibrators from the Saranya, she’d cum hard from that and experienced a level of pleasure like never before. This contact with Sora hit differently. Not only was she pulsating with raw sexuality and experiencing the electrifying sexual release, but her heart was full of love. She was elated just looking at Sora, touching him, and feeling him inside.
What they each expected to happen was to fall exhausted to the side to pant and moan and bask in the afterglow of their post-coital bliss, yet that never happened. Sora pulled himself from Kairi but his erection didn’t die down, nor did Kairi’s stop wanting to be filled again—to be touched again.
“Wha—?” Sora exclaims.

Saranya runs her slime hand from Sora’s leg to Kairi’s, giving the pair a smile while they look back at her. “Don’t worry you two, it’s just a little spell that’ll let you keep going, don’t stop on my behalf, in fact, let me help.
Animated waves mound up from the slime behind Sora and Saranya grabs the back waistband of the diaper. Sora, unable to move due to the rest of the slime holding him down. He gives a concerned look back, just for a second pulling his attention away from his partner just in time to see the waves of slime start to pile into the back of his nappy. As the slime passes his waistband Sora finds himself surprised at the texture. It’s different from the bed they rest on or the hardened strands that are holding him and Kairi together.
The mass dumping into the back of his pants is warm and squishes pleasantly like when he gets to be alone and dump a pitcher of oatmeal into his diaper. The texture of the onslaught of slime is astoundingly similar but here he’s not at risk of running out, the weight pulling at the crotch of his nappy and encroaching his lowers. Fighting against the trajectory of his own diaper was another growing mountain of plastic below him.
A quick glance reveals that Kairi’s diaper is also expanding with the slime bed’s material transmuting and shifting inside of hers as well.
The warmth from the mush fills the space in their diapers rapidly, faster than even the magically enhanced plastic can spread. Sora can feel it around his member through the portal to Kairi’s diaper, a gradual rise that threatens to envelop his dick.
He looks down at Kairi, still huffing from his exertion. “Again?” he asked.
Kairi nods and looks at Saranya. “This time I want to be on top.” she says, addressing the slime succubus directly.
Saranya nods, using the slime bed to shift the pair around. The cords hold Kairi's release, giving her a moment to get comfortable while Sora is brought into position, his heavy overfilled nappy rustling and shifting pendulously while he’s flipped onto his back.
Slowly and carefully the strands around his legs shift and tighten, bringing his knees up by his ribcage and leaving his feet in the air. Saranya directs Kairi to take her position above the tent in his padding, aligning their portal holes for access. Recognizing the position she clambers over excitedly, spreading her thighs wide to kneel with her legs on either side of Sora’s. Even before the idea of diapered sex this is somthing she's been waiting to try for a while.
Her diaper thwomps heavily on top of his, stacking to double the insane slime and piss-soaked bulk. The portals in their diaper once again align. She’s hovering now, giving Sora a coy smile as she teases his head by running the lips of her pussy over it. Slight shivers run through him.
Kairi can tell that Sora wants to move, to buck his hips upward and enter her, but she remains just out of reach teasingly. With her hands free, she reaches back and undoes the clasp of her bra, leaving the lacy underthing to fall free while her breasts bounce invitingly in front of Sora’s gaze.
The thought strikes him at that moment that he’d like to suckle them. However, his inability to move restricts him. Kairi smiles, seeing whatever desire is there. She doesn’t know exactly what it is but she wants to give what she can to it.
“My turn.” she says.
Without warning Kairi drops her torso down, bringing her bare chest to Sora’s and pressing her breasts against him. She keeps her hips raised, still withholding that final bit till she is ready.
Ragged breaths were emanating from both of them. Saranya’s hand rests on Kairi’s back and the other on Sora’s leg. “Do it…” she whispered.
Kairi brings her whole pelvis down in one swift motion, slamming Sora’s cock into her with intense force. He slid in easily, showing how excited about the mating press she was.
Moans slid from between the pair as Kairi’s hips rocketed upwards again, coming back down with equal force. She was in control now, driving the tempo with intense sexual drumbeats as she felt Sora’s cock slide in and out of her. The length of his member was rubbing repeatedly against her clit with each thrust, egging her on to keep up the pace and push for more.
The vocalizations shared between the two grow louder as Kairi humps her tied-down lover, outright riding him with just her hips, bouncing up and down while embracing him with her whole body. Her hands slide across his chest while he slides into her. Like a fish looking for water, she searches for his lips.
They locked with hers creating a deep and passionate kiss. Lips smack in unison with their pelvises as Kairi rides the length in Sora’s pants. With each motion, she feels herself get closer to that promised release and feels the rising of cum from Sora too. The kissing lasts until they each reach a pulsating climax with Kairi spasming on top of her lover and Sora’s body tensing as he, once again, cums inside his entwined lover. Only when the electrifying sensation passes do they come up for air.
The switching of positions continues for hours, a long, intense, and unstoppable session of passionate, lovey sex all overseen by the slime succubus Saranya who watched and aided with a pleased expression. She adds little things here and there, lifting a leg when needed or offering vibrating bullets or her “wand” hand. In the background she kept them going with magic that eliminated their sexual fatigue. A magical little blue pill for both of them, so to speak.
The pair happily agreed to her help, enhancing the experience of their lovemaking with her bondage and toys. What really made it for each of them though was the diapers. Feeling the squishy slime-filled sack bounce as they pleasured each other heightened their sensations, driving them to try more.
With doggy style, Kairi’s diaper not only provides a satisfying cushion but Sora’s added a weight that drove him harder, swinging with him to increase the strength of his thrusts. While Kairi bounces on him cowgirl style, the diaper hugs her and smushes against Sora with a pleasing weight that keeps the intensely sexy fact that Kairi was diapered at the forefront of his mind.
Time loses all meaning to the pair and when Kairi rolls off of Sora for the last time they feel the effects of tiredness running through their bodies. Saranya beams at them, now standing above them fully. Somewhat weakly the pair stare at her.
“Thanks a lot you two, not only did you provide a good show but now I’ve got all the power I need to get home. It was nice meeting you!”
And like an old friend leaving a party, the slime succubus turned to leave, opening a door of darkness with her dripping hand and walking straight through, leaving the sweaty slime-covered pair staring in amazement.
Both of them wished they could have said something or stopped the Succubus, but before they could the portal closed, leaving them alone in the cave.

Back at their shared apartment Kairi lay back on the changing table, waiting for Sora to finish powdering her bottom and recalling the hazy events between their succubus-aided fuck fest and getting back here.
With the succubus Saranya gone they were left in the excess bed of slime, having to wait while the strands dissipated to be free of its magically gentle pull on their limbs. When they finally could stand they were diapered and without clothes, left to waddle back with the soggy, slime-filled diapers slowing them down.
Within the comfort of their home, they allowed the diapers to plop to the floor heavily, before stepping into the warm, cleansing waters of the shower. Kairi helped Sora wash up after the experience, running a loofah across his bare skin slowly and gently, taking her time to admire his form with every slow pull of the cleaning cloth.
He similarly did the same for her, taking a little too long in certain areas as he got distracted by her body. She’d gently chide him with a kiss and remind him other parts also needed washing.
Once both felt satisfactorily clean they toweled off and made for the changing table, knowing how important it’d be for them to get back into new Keyblade Kuddlers before an unfortunate accident occurred.
A contented sigh leaves her lips as Sora tapes up her diaper and offers his hand to help her up.
She takes it gratefully, only to find it’s a rather cruel trick to pull her over to the bed on the other side of the room. She flies through the room after him, landing on the soft comforter atop their bed next to him.
A little scramble is all it takes for them to cuddle into each other, Kairi repays Sora’s trick with a poke in the ribs and a peck on the cheek.
“I can’t believe I waited so long…” he says wistfully.
Kairi nods. “Me neither, and never again, alright?”
“Of course—there’s hardly any reason to go back to how things were.”
She laughs, nuzzling into him. “We can’t be too long, we’re going to have to track down Saranya after all. At least to thank her.”
“Oh yeah?” Sora asks.
Kairi nods again. “That’s a problem for tomorrow though, tonight I just want to relax and snuggle you.”
Sora agreed with her and the pair held each other till they fell asleep, dreaming sweetly of the time they shared in the beautifully lit cave with an encouraging friend.
