It had been a monumentally unproductive week. Anna made sure of that.
Lilith was used to operating in kinky conditions, sure. It was her job. Under normal circumstances, she could be tied up, gagged, blindfolded, and fucked in every available orifice without batting an eye.
What Anna had done, though… It was simple, straightforward, and utterly humiliating.
After their incredible evening together, she had let Lilith leave.
She had not removed Lilith’s diaper first, or the vibrator that was inside it. Given the sigils marked on the front and back, Lilith couldn’t remove it herself, leaving her… helpless.
Thanks to her demonic form, she didn’t have the same concerns that a human might in her condition. She was all but impervious to mortal maladies, especially anything that might impede in sexual play - she wouldn’t be a particularly effective succubus, otherwise. Even so, her nose worked as well as anyone else’s, and she could do absolutely nothing to escape the smell of her packed-full diaper, or the squelch and squish that accompanied her every time she moved, or the heavy sagging garment that none of her clothes could completely hide.
When Lilith had protested, Anna had stonewalled. “Babies don’t get to decide when they get changed,” she had pointed out. “And I don’t want you to be able to hide exactly how helpless you are.”
To make sure this sank in, she turned on the vibrator and ran it until Lilith sank to her knees in an orgasmic puddle.
Once she’d regained her senses enough to complain again, possibly fishing for the same sort of response, Anna had given her a simple ultimatum.
“You can always use your safe word.”
Oh fuck.
It was one thing to be dominated by a human - That was common enough for short periods. But to be forced into using her safe word by a human? Lilith would never live it down if word of that ever got out. She’d be a laughingstock, far more than if her friends just got a whiff of her diaper.
So, Lilith had gone home without a change.
Since then, Anna had stayed in contact, teasing Lily, flirting, even demanding diaper checks just so Lilith would have to take photos in order to prove what they both already knew. Lilith put up with it, because her obedience was always rewarded with a burst of pleasure from the vibrator.
When Lilith had protested, two days later, that her diaper would leak if she didn’t change, Anna had apparently relented. She invited Lilith over, tied her up, and then ran a Wartenberg pinwheel down the diaper half a dozen times, explaining that Lilith was free to add another layer, and change that out as needed.
It did, admittedly, solve the issue of leaks - but it left Lilith trapped in her mucky, heavy diaper, and only added even more bulk to her wardrobe, since she now had to wear two layers at a time or leak onto her clothes.
The next day, Anna decided that Lilith would need to ask permission just to change her second diaper, too.
As the natural result of all this, Lilith’s work suffered. She could mask the smell of her diaper to any human she was trying to seduce, but only the humans she was trying to seduce. Bystanders would still wrinkle their nose when she waddled past, and she couldn’t ignore it herself no matter how hard she tried.
On the sixth day without a change, a colleague had finally come to check on her. His arrival at her infernal abode - that is to say, her apartment - wasn’t a surprise, but it still caught Lilith off guard, and she didn’t have time to try and mask the smell that had permeated her living space.
Irdu, a particularly experienced Incubus, didn’t bat an eye when he walked in, though his nose did wrinkle. “Lilith,” he said, glancing around. “I came to check on you, you haven’t been seen at the office lately and-”
“And my contribution to the souls of the damned have been late,” Lilith nodded, tugging down on her skirt a little, as though it would hide the drooping double diapers she was wearing. “Yeah, about that-”
“You’re stuck on a case, I presume?” Irdu asked, looking her up and down. “I know how we can get fixated on a single target at times, making it difficult to seduce any others.”
“Yes!” Lilith said, perhaps a little too quickly. It was a solid excuse. “That’s it. This one particular human has a humiliation kink, and… maybe I’m getting a little carried away, but you know how it goes.”
Irdu nodded. The excuse was acceptable. “Of course. So long as you’re not shirking your duty, we won’t need to revoke any privileges, but do try and let us know the next time you are delayed.”
Lilith smiled, nodded, tucked her hair behind her horns. It was a little embarrassing to be chided by one of the higher ups, but that was alright. They would think she was just passionate about her work.
While she was talking, her phone chimed on the coffee table. Anna had the worst - or possibly the best - timing.
Lilith would have ignored it, but Irdu saw the phone buzz and raised an eyebrow. “Work?”
“Yeah,” Lilith had to lie, checking the phone.
Anna’s message was written with a plethora of emojis. “How’s my stinkiest little baby? 😘 😏 I haven’t seen your mushy tush in a while - time for a diaper check. 😉 😄”
Lilith blushed, glancing at Irdu. He only shrugged. “Don’t let me get in the way.”
Her cheeks darkening further, Lilith lifted up her skirt, snapping a selfie of her heavily sagging diaper and her own blushing expression. Typing out a quick response, she asked, “Can I change soon please? 🥺”
Anna’s message came a second later. “Pee-ew! I can practically smell you from here. 😘 No change for your poopy bottom today. Ask me nicely in the morning.”
Lilith read the message, and let out the tiniest little whimper.
Irdu noticed.
He didn’t comment on it, but he raised one eyebrow, clearing his throat. “Well, I should get going. Once you have an ETA on how long you’ll be dealing with this particular human, let us know.”
“Y-yeah,” Lilith said, swallowing. Crap.
Her phone buzzed again as Irdu left, and she glanced down at it. “Send me a pic that shows how much you love your diapers, and I’ll let you have some fun.”
Lilith swallowed again, waiting for the door to click shut before she got on her knees and posed for the camera. She could deal with this problem later.
…
Two days later, and eight days without a diaper change, Lilith finally got Anna to invite her over so they could talk. Showing up on her doorstep, diaper drooping, a hint of an itch starting to get her attention despite her resilience against diaper rash, Lilith waited for her to answer the door.
Anna obliged, a huge smile on her face as she answered. “Lily- Oh, gosh,” she screwed up her face and put her hand over her nose, pinching it. “You really stink.”
Blushing, Lilith said, “I can mute the smell for you, since-”
“No, no,” Anna smirked. “It’s just- I know I’ve been teasing you all weak, but it’s a good reminder of just how pathetically helpless you are, Lily.”
Lilith shivered. “Can I come in?”
“Of course.” Anna let her through the door and gestured, not to the couch, but to a small area in the corner of the room, where a low plastic fence had been set up. A play pen. “Have a seat. I want to show you something.”
“Er…” Lilith said. “Okay, but-”
“Hush, Lily. We can talk in a moment,” Anna instructed. “Sit. That wasn’t a suggestion.”
Wobbling as she stepped over the play pen fence, Lilith obeyed. No matter how long she was in her diaper, she still couldn’t just ignore the massive squelch and squick that came when she put her weight down and sat.
Anna caught her little squeak, but didn’t comment, sitting down on the couch and opening a package. “I just had this show up today,” she said, reaching inside and taking out a bright red onesie, with a locking set of runes and sigils emblazoned on the front. A silly decoration to most, an impenetrable trap for Lilith. “What do you think?”
“It’s… adorable,” Lilith admitted, her interest piqued in spite of herself. “I love it.”
“Arms up, then,” Anna said, standing and walking over.
Lilith hesitated. “Anna…”
She rolled her eyes. “You’re already trapped,” she pointed out. “If anything, this’ll help keep your stinky diaper contained.”
“That’s not it,” Lilith said. She did want to try it on, though, so… she started shirking out of her clothes. “Okay, but after this I really need to talk to you.”
Anna smiled, waiting until Lilith had disrobed - except for her diapers, of course - and lifted her arms. Once that was done, she pulled the onesie down over her, pushed Lilith back so she could tug up on the snaps, and finally lock the onesie into place. “How’s it feel?”
“Snug,” Lilith said, testing out her range of motion in the onesie. “Comfy, but…” she frowned, moving her legs experimentally. Even moreso than before, when it was just from the bulk of her diapers, she couldn’t close her legs properly.
“A bit of spacial magic,” Anna beamed. “It’s a waddler onesie. I’d be surprised if you could even toddle around with that on, though - you’ll be better off crawling.”
“Oh.” Oh fuck me- Lilith had only a moment to consider this before Anna thumbed the remote control she’d been hiding, giving Lilith a pulse of intense pleasure to accompany the realization of how helpless she was.
It was a good thing she was already on the ground, because as she squirted into her diapers, if she hadn’t been seated, her legs would have buckled.
“Now,” Anna said. “What did you want to say to me?”
“I…” Lilith swallowed. “I need out of this diaper. It’s interfering with my work. This has been fun… So fun, but it needs to stop.”
“Then use your safe word,” Anna said. “It’s as simple as that.”
“Okay, but-” Lilith’s cheeks darkened with a blush. “I can’t.”
“You can’t, or you don’t want to?” Anna asked.
“The other seduction demons wouldn’t let me live it down,” Lilith explained. “If I- Look, being outdone by a human is embarrassing, okay?”
“More humiliating than being turned on by filthy, heavy diapers?” Anna asked, her voice a teasing purr. She clearly wasn’t taking this conversation very seriously.
“Yes!” Lilith said. “I- I need to get back to work.”
“What happens if you don’t?” Anna asked, genuinely curious, tilting her head.
“I could have some of my demonic powers revoked,” Lilith said. “Teleportation is the big one, and knowledge of mortals who are in need of seduction and destruction… Most of my more reality altering powers. Anything where I need to channel the true infernal energies, really.”
“Hmm.” Anna frowned. “Okay, well… I don’t want to do this if it hurts you.”
“Thanks,” Lilith said, squirming uncomfortably on the floor as she looked up at Anna. “So…?”
“So…” Anna thought for a moment. “A deal. You drink a bottle of formula, and I’ll tease you the whole time. Then, just say the word and I’ll let you out.”
“No tricks?” Lilith asked.
“I didn’t say that.”
Lilith swallowed. Either way, she was relying on Anna’s good faith - if Anna wanted to truly hurt her, she would just have to break the implicit promise of the safe word. It wasn’t a binding contract, and as long as she was bound with the sigils on her onesie and diaper, there wasn’t much Lilith could do about it.
“Okay, fine.”
“Then wait here, I’ll be back in a moment.”
“Oka- aah!” Lilith gasped, as Anna turned on the vibrator.
“That should keep you busy for a few minutes,” Anna snickered, leaving to go make Lilith’s bottle.
Whatever setting it was on seemed calibrated to be particularly frustrating. It pulsed, quicker and then slower, each time bringing Lilith just to the edge of orgasm before backing off. It was infuriating, frustrating, hellish - Lilith was a demoness of great power, and she was being tortured. It was unjust! It was unfair! She wouldn’t stand for it!
When Anna returned a minute later, Lilith was on her back, desperately rubbing at the front of her layered diapers and onesie, helplessly trying to create enough sensation for a proper orgasm. Anna made sure to get a photo before she turned off the vibration, snickering.
“Here,” she said, passing the bottle down to her particularly frustrated succubus. “Drink up.”
Lilith glowered. “That was cruel, Anna.”
“Maybe,” Anna said. “Drink up.”
Taking the bottle, Lilith started to suckle, looking up at Anna as she got her first taste of the formula.
The honey-sweet, warm, perfect formula…
“That’s good, little Lily,” Anna said, standing over Lilith as she held the bottle, feeling the formula run down the back of her throat. “Just keep drinking, my stinky, smelly little girl. I know you love it - no matter how much you protest, it’s obvious that you don’t really want a diaper change at all, do you?”
Staring up at her, Lilith felt something… odd. She felt as though her eyes were glazing over, but her vision remained perfectly clear as she stared up… at…
“You just love your filthy diapers, so much,” she continued. “You love that everyone can tell with a sniff how helpless and desperate you are, how you’ve got no control, how you can’t even make it to the potty like a big girl. You wouldn’t have let me trap you, if you didn’t, and yet here you are. Isn’t that right?”
Lilith couldn’t look away. Her bottle was half empty now, and she kept suckling it, almost automatically, looking up at… What do I call her?
She beamed, crouching down a little so she could reach over and squeeze the front of Lilith’s diaper. “I’m surprised anyone could ever mistake you for a big girl, but that’s what this is for - To ensure that nobody makes that mistake. You’re just my powerless, diaper filling little-”
“Mommy?” Lily mouthed, over the bottle, a bit of the formula dribbling down her chin. The bottle still had a bit left to go, but Mommy reached down and pulled it away from her lips anyways.
“That’s right,” Mommy said. “Good girl, drinking it up for me.”
Lilith’s thoughts felt like they had to force their way through cellophane for her to put them into action. Something was in the bottle that was making her feel this way, but all she could ask was, “Bottle?”
“You can have the rest soon,” Anna said, missing the point of the question, possibly deliberately. “But I think you’re where I want you to be for now.”
Lilith thought about the answer. Of course, yes. I have responsibilities. She tried to say it. Her mouth answered, “No.”
She blinked.
“I mean… no. No! I do not want to be independent!” Her eyes widened.
“The potion I mixed into your formula,” Mommy explained. “It’s not quite a truth serum, but it brings out whatever your subconscious was already thinking. Everything I said while you were drinking, it’s true, isn’t it?”
“Yes…” Lilith was forced to admit, though her blush still came through.
“And I heard you call me ‘Mommy’, which tells me a lot about where your headspace is at,” Mommy continued. “If you drink the rest of your bottle, you won’t be able to control yourself at all. For one, you’ll be totally obedient to anything I tell you to do, but aside from that, your subconscious will be in total control. If that’s something you want, well… you know what to do.”
“How long will it last?” Lilith asked, tilting her head. She wanted that. She wanted her Mommy to have that kind of power over her.
“A few days, but of course, I’d be a bad mommy if I didn’t make sure my baby got her milk regularly,” Anna’s eyes sparkled.
Lilith’s anxieties spiked. She would be laughed at by her peers, lose her demonic privileges. She would never live down being the succubus that willingly gave in to such complete domination by a hum-
The bottle was already between her lips and she was suckling it. While her mind had worried, the rest of her had decided.
Mommy smiled. “That’s my good girl. You should call yourself Lily, though. ‘Lilith’ is a name for a grown up, not a smelly little baby.”
It didn’t take long to finish the rest of her formula, and when she was done, Lily squirmed in delight, giddy at feeling her enormous diaper smush beneath her. It felt so good, and even if she smelled bad, that was just a reminder that her mommy was in charge.
In fact… while she didn’t strictly need to use her diapers very often, there was no reason why she couldn’t go as often as humans did, and if her diaper was more full, it would render her that much more pathetic and dependant.
So, scrunching up her face, she let out a soft little whimper and pushed, feeling the gurgling inside her diaper as the old mush made way for even more, warm and foul. It wasn’t the torrent of messing that she’d done the week before to originally fill her diaper, but it did make the padding bulge out just a little more, and it was obvious to Mommy what she was doing.
When Lily was done, she smiled, blushing a little as she looked up at her mommy, seeking approval. Mommy’s smile was all that she needed.
Mommy nodded. “You really can’t help it at all, can you?”
Lily shook her head.
“Well, that’s why I didn’t bother changing your diaper - I knew you’d just fill it up again,” Mommy giggled.
There was just one thing that would make this better. “Can you turn on the vibrator, Mommy?”
“Now,” Mommy said, a wicked smile playing across her lips. “I’ve been nice to you today, haven’t I? I gave you a nice bottle, and a new onesie, and I even put up with the smell from your incredibly poopy diaper. You even got to have an orgasm already!”
“Uh-huh,” Lily confirmed. “And now I want another!”
“I think not,” Mommy said. “You’ve had too many lately, and I think you’re getting spoiled. First, I think you should lay back and show Mommy what you can do with your mouth. Then, if I feel good enough, maybe I’ll let you have some fun. Or maybe I won’t - it’s not up to you any more.”
Lily shuddered with excitement, laying back obediently.
“Use your powers to make sure I don’t get dehydrated, Lily,” Mommy added, as she slipped out of her skirt, revealing that she hadn’t been wearing panties this whole time. “I want this moment to last.”
“Okay!” Really, it didn’t matter if she got to feel the vibrator or not.
As long as Mommy was in charge, Lily was happy.
The end.
I'm really glad this got to be a three parter! This feels like a very natural place for their story to go, and I'm really pleased with how it turned out. I might end up putting this together as a novella!
Also, hey, look at me! Only a day late! That's practically on time, given how busy this month has been. Good news: Things are going to be a lot more reasonable next month.
Even better news: We hit our next stretch goal! Starting in April, we'll be getting a chapter a month for a new story that's just for my Patrons. I'm really excited about it, and I hope you do to. More info to follow later, once I have it ready in announcement format!
