A Mother's Mistake - The Full Story (Patreon)

Lucile sat beside the giant crib.

Inside, her thirty-year-old older sister slept as she sucked on a pacifier. Her diaper was already wet, but that wasn’t surprising. It’s been months since Elle slept on her own bed with her husband. It’s been months since anyone thought of her as anything but the pathetic oversized baby she was.

The once proud mother was now the baby. The thought of it still made Lucile smile, even after all the diaper changes and tantrums. Having Elle reduced to nothing but a crying infant had been her most rewarding task. And the funny thing was, it didn’t take that long.

Elle moved inside the crib. A familiar noise flooded the room just as Elle flooded her diaper. Even if the former mother wanted her life back, Lucile doubted she could ever make it without wearing diapers twenty-four-seven.

In just one weekend, her sister went from being the upper-class queen bee to her little girl.

And it all started with a simple suggestion.

Chapter 1

The Regression Proposal

Elle thought it was an innocent idea.

Her younger sister, Lucile, had explained that in order to be a better mother, she needed to understand how her daughter felt. It did make sense. Her daughter, Camille, was almost three years old now, and things had not been good lately between them. Elle had tried to potty train her. She had tried to build a better relationship — the kind her own mother had never given her. But no matter what she tried, she couldn’t connect with her daughter. Thankfully, she had stopped breastfeeding. It had not been a pleasant experience for either of them. Neither was playing, napping, or watching cartoons. Nothing seemed to make things work. It was as if Camille didn’t recognize her as her mother. But why? Since they returned from the hospital after giving birth, Elle had asked herself that question.

In Elle’s mind, she was not living up to being a mother, and that was weighing on her and her personal life to the point that she had not slept with her husband for over a month already. He had moved to the guest bedroom and was disconnecting from her further and further every day. Afraid that it could end her marriage, she had turned to her most trusted friend, her younger sister, Lucile.

“It’s all about helplessness,” said Lucile while helping Elle babysit, “If you don’t understand what’s like to be helpless, then you cannot take care of a helpless infant, can you?”

“That’s a bit of a stretch, don’t you think?”

“And yet, it works wonders. At least with my patients.”

“What do you mean by helpless?”

“Well, it’s obvious. You need to be treated like a baby again, around the age of your daughter, of course. That’s how you can connect with her. You’ll play together. You’ll be bathed together. You’ll eat together. You’ll sleep together. Among other things.”

“How do you come up with this kind of stuff? And how do you get people to agree to it?”

Lucile chuckled, “Well, because it works. That’s why my clients pay so much money. It just works. If I wasn’t good at it, I wouldn’t be this successful, Sis.”

Elle turned her eyes to her baby girl, Camille, who was playing in her playpen, unaware they were discussing her. And if she was aware, she just didn’t care. Infancy, thought, Elle. What a time.

Camille even seemed happier with Lucile than she did with her, and that made Elle feel like the worst mother on earth. Perhaps her sister was right. Perhaps she could try to connect with her daughter through some role play, and if she could do so, maybe she could make life with her husband better. And she could finally have the happy family she’d always wanted.

“How do we do it?” asked Elle.

Lucile smiled.

“Next weekend, I know Steve is gonna be traveling for work. Why don’t I come and become Camille’s and your caregiver? I will treat you both the same way, and you’ll get in touch with your baby.”

“Like the same the same?”

Lucile nodded.

“You know, diapers and stuff. It’s important for you to feel that so you can understand what it’s like for your daughter.”

“You mean wearing or using?”

“Well, both.”

“I don’t know, sis. It sounds too wacky. Do your patients really do it?”

“Oh, yeah. So many of them, and some actually enjoy not having any care in the world for a couple of hours a week. Although the one that suffers it is me, changing an adult’s diaper is not the same as changing a baby’s.”

There was a short moment of silence.

“So, what say you?” asked Lucile.

Elle sighed, “Alright. But don’t tell anyone about it.”

“It’ll be our secret.”

Steve left Friday night as expected. He gave Elle a small kiss, but there were no goodbye words or anything. He did, however, tell Camille that he loved her and that he was going to miss her so much. Elle did her best not to take it personally, but it made her cry herself to sleep that night.

The next morning, Lucile knocked at her door quite early. She seemed eager to start the experiment as soon as possible.

“I have everything we need,” She said, carrying a couple of bags, “So you don’t have to worry about anything.”

Elle smiled thinly, trying to help her sister carry the bags. But Lucile stopped her immediately.

“Hey, you are a baby today, remember? You do nothing but what I tell you to do. Alright?”

Elle nodded.

“Where’s Camille?”

“She’s still sleeping.”

“Good. That gives us enough time to get you ready.”

“Ready?”

“Yes. So come with me. We are going to give you a relaxing bath.”

“I can bathe myself.”

“Adult Elle can. But you are not adult Elle, right?”

“I guess so.”

Lucile took her sister’s hand and dragged her upstairs to the master bathroom. One of the perks of Steve’s job was that they did not have to care about spending, and their bathroom was a sign of it. It was beautiful and elegant, from the tiles to the glasses and everything in between.

“Alright. I’ll get the bath running. Why don’t you help me and get naked? Get into the shower, and I’ll be with you in a minute.”

“I don’t know, sis. It sounds weird to be naked in front of you.”

“Oh, honey. I’m going to see you naked more times than your husband has in a while. At least this weekend. There’s nothing to be awkward about. I’m a professional today, okay?”

Elle nodded again and did as told.

She really wanted to connect with her baby. She really wanted to connect with her husband again. And if she had to be a baby for a weekend, well, it was just a weekend. She could do it. It was all for a purpose. It’s not like she was going to enjoy any part of it. So she got naked and walked into the shower while her sister started the bath. She wasn’t sure why she needed to shower before her bath, but she supposed Lucile had something in mind, and she was the expert, after all.

“Alright, now let’s get your body ready,” said Lucile, also getting naked.

Lucile was just five years younger than her older sister, but her body seemed out of Elle’s league. She was tall and curvy, with long blonde hair and beautiful, massive breasts. Elle’s breasts were also big, though it was mostly because she still breastfed Camille. A bit shorter than her younger sister. She didn’t look thirty-two years old, but she also didn’t look twenty-two.

“Ready?” asked Lucile.

Elle nodded.

Her sister cleaned her carefully, paying extra attention to her most private parts. But it was not just the washing that caught Elle off-guard. Lucile also applied some sort of cream around her body. Once the cream was washed away, Elle saw her smooth skin lose every sign of body hair, including her pubes. Feeling even more naked than before, she rushed to cover herself.

“Is this really necessary?!”

Lucile just nodded, “It is. Believe me, you don’t want to use your diapers while having pubes. It’s a recipe for disaster.”

After the shower, Lucile helped her older sister into the already-filled bath. She gave her a rubber toy, as if she were a little girl, and left her there for a while. Five minutes passed, and Elle decided to play with the rubber toy as there was nothing else for her to do. During baths, she would usually read a book while drinking some wine, but that wasn’t really an option.

“Let’s get you out,” said Lucile, still naked, though completely dry by now.

Carefully, Lucile dried her older sister and then took her to the master bedroom. There, waiting for her, Elle could see why her younger sister had left her in the bath for so long. There was a pile of diapers of every color on top of the king-size bed, and they were not baby’s diapers. No, those were big enough to fit an adult, big enough to fit Elle herself.

Diapers weren’t the only thing in bed.

Baby powder, baby wipes, and colorful clothes that looked like they belonged in a toddler’s closet but were big enough for an adult, among other things one would find in a nursery.

“Sis, what’s this?”

“Alright. I will lay down the rules now. This weekend, I’m not your sister. This weekend, I’m your mommy. Understood?”

Elle chuckled.

“You think it’s funny? You’ll have a change of heart when I spank you until you are a sobbing mess.”

Elle said nothing, but a fast chill traveled through her spine, making her tingle a little. A few drops of pee rolled down her smooth and long legs. Lucile must have caught it because she smiled, getting closer to her younger sister and placing her hands right over her pussy, making Elle blush.

“What are you doing?”

“Did you just pee a little?”

Elle blushed.

“You did, right?”

“It-It’s a normal thing. A lot of women get slight incontinence after birth. You must know that.”

Lucile chuckled, “Well, diapers will come in handy, then.”

“Don’t laugh. It’s not funny.”

“No more talk,” said Lucile, towering over her sister, “The experiment won’t work unless you get into character. So, from now on, you either get this,” she paused, showing a pacifier, “Or your thumb on your mouth. If I ever see you without either, you’ll be spanked. Understood?”

Elle thought about complaining, but she thought it better. She had never been able to stand against her younger sister, and she felt sorry because Lucile was actually doing all of this to help her.

So she nodded.

“Bathroom is off limits,” said Lucile, grabbing Elle by the hand and placing her carefully over the bed, “So it’s diapers for you until the end of the weekend.”

Elle looked away as her sister diapered her. She had worn them before after giving birth, albeit none as childish as the one Lucile had just put her on. She blushed quite red when Lucile spread the baby powder over her private parts and then again when she taped the diaper, trapping her crotch in the fluffy prison. Finally, Elle was dressed in a onesie that resembled something her daughter would wear.

“Last rule. What mommy says,” said Lucile, helping Elle stand up, “What mommy says goes. No complaints. If not, well, you know.”

Elle nodded.

There was a short moment of silence as Lucile scanned her older sister. She must have been pleased with herself because she smiled as she had done whenever she won something. Without hesitation and with an overpowering grip, Lucile took Elle in front of a mirror and forced her to see her own reflection.

What Elle saw in the reflection wasn’t her. It couldn’t be. Staring right back at her wasn’t an adult. It wasn’t a mother. It was a little girl, a rather tall one. Her pink onesie did nothing to hide her diaper. And compared to her younger sister, who was still naked and standing next to her, Elle felt like such a small being. Pathetic. Childish.

And that made Elle start to sob.

“It’s okay. Mommy’s here.”

Elle hugged her younger sister the way a little girl would hug her mother when they cried. Lucile wasn’t expecting it, but she didn’t say anything. She embraced her diapered older sister, holding her tight, which only made her feel warm inside. A sort of warmth she had not felt before.

“Shall we start the weekend?” asked Lucile, cleaning her sister’s face from tears.

Elle nodded, feeling better now. Though, she was unsure of what her younger sister meant by starting the weekend. It couldn’t be worse than this, could it?

Chapter 2

Mommy’s Milk?

Before leaving the room, Lucile took it upon herself to make the most of Elle’s current state and place a pair of knitted baby slippers on her sister’s perfect feet. The thick diaper, the onesie, the pacifier in her mouth, there was no way she could ever see Elle as her older sister ever again, and that’s what she wanted.

She grabbed Elle’s hands and led her off the room and into the hallway. It could’ve been the thick diaper, slippers, or both, but Elle fell to the ground after a few steps.

“Are you okay?”

But she wasn’t.

As far as Elle’s bladder was concerned, that little fall was enough to release a torrential flow of urine right into her fresh diaper. She didn’t stop; she couldn’t. She just stayed on the ground, on all fours, avoiding her younger sister’s eye contact. She shamed herself, hoping it was all a nightmare.

It wasn’t.

“Did you just peed yourself?”

Elle didn’t answer.

The warmth of her own pee spread around the thick padding between her crotch. To her surprise, it wasn’t the most unpleasant feeling, far from it. In a weird, twisted way, it awoke in her a feeling of arousal, though it was obviously not something she could tell her sister, so she just blushed as she kept disgracing herself.

“Here, let me help you.”

Lucile helped Elle back to her feet, though it was more than obvious that walking wasn’t an option for the diapered mother. So, with very little effort and no hesitation, Lucile grabbed her older sister’s diapered bum and carried it like a mother would a little girl.

“Let’s get you something to eat before your big sister wakes up.”

“Big sista?” asked Elle, still with the pacifier in her mouth.

But Lucile didn’t answer.

She took Elle to the living room, pressing against her diapered crotch with one hand, though unknown to her, her older sister was fighting back the need to moan with every step. Perhaps it was the excitement of something new or the fact her own husband had not touched her in so long, but there was no doubt that when the weekend was over, she would try it again. She could maybe get Steve to get involved. Reignite the fire and be bold, yes.

Maybe it wouldn’t be a waste of time, she thought, enjoying her sister’s hands pressing against her diapered crotch around her wet diaper.

“While Camille is sleeping, we might as well try some of this,” said Lucile, sitting on one of the couches in the living room, “Ready for mommy’s milk?”

That sentence was confusing to Elle in so many ways, who had just sat on top of her younger sister’s lap. Before she could protest, Lucile removed her pacifier and began pushing Elle’s head against her nipple. There was a bit of resistance, but there was no escape.

It had been a morning of many first times, and it wasn’t over. For the first time since she was a baby, she felt the sweet nectar of a woman’s breast milk invading her mouth and running down her throat. Elle tried to fight back; she wanted to push away her sister and demand a full stop to their agreement. She had taken things too far.

But she didn’t.

No, she just sucked. Tears ran down her cheeks because it wasn’t just the fact her sister was humiliating her. No. Elle was crying because she was enjoying it. The wet diaper, the breastfeeding, the clothes, all of it. Now, her crotch was moving rhythmically as she sucked, something that didn’t go unnoticed by Lucile. However, she had bigger plans, and her sister’s enjoyment of her treatment, though welcomed, was never a priority. No, no, no. Little Elle knew very little about her sister, but she was going to find out soon.

“That’s it. Good girl,” Lucile kept saying as she caressed her sister’s hair, “Drink it all, my dear. It’s all yours.”

Elle’s tears began fading. At the same time, her eyelids got heavier and heavier.

It was a bright sunny day in the country club. All the rich and powerful gathered there every weekend, men with their golf and women with their gossip. It was in the latter group that Elle found herself daydreaming. She wasn’t sure how she got there, but she was sure that whatever Mindy, a young and ambitious new arrival in society, was saying, had perhaps been a bit too boring for her.

Her eyes gazed upon a butterfly that flew around the terrace and stopped at her table.

“Elle,” she heard Mindy saying.

She turned to face Mindy.

“Yes?”

“Do I have your attention?”

Elle hesitated, “Yes.”

“Good, so you can stand up and elaborate on it,” said Mindy, smiling devilishly.

Elle stood up.

She didn’t know what they were talking about, probably something awful. But all eyes were on her now, and she couldn’t come up with an answer. They were judging her. They were judging how she was dressed. Her clothes seemed picked for a five-year-old and not an adult woman with a daughter.

They whispered horrible accusations and mocks.

And Elle’s eyes began getting watery; she was now fighting back the tears. Her heartbeat was running fast. And her legs were shaking. And there was a warm sensation around her crotch and running down her legs.

Elle looked down at the big puddle of urine that had formed around her feet. And now she couldn’t fight back the tears. Just like a toddler, she cried. She couldn’t understand why everyone was so mean. She was just a little baby, and babies weren’t supposed to make it to the bathroom. But babies wear diapers. Where were her diapers? Why wasn’t she wearing one? Where were her mommy and daddy and sister?

Everyone burst into sadistic laughter.

Elle tried to run away, and then…

“Wake up, sleepyhead. Waky waky.”

She opened her eyes and saw the familiar face of her younger sister.

“Are you okay?” asked Lucile.

Elle nodded.

“You’ve been sleeping for almost an hour.”

“Have I?”

Lucile nodded, “You’ve soaked your diaper full; I better change you now before it starts leaking.”

“What?” asked Elle, still disoriented.

Lucile gave Elle no notice before she undressed her right in the middle of the living room. Windows wide open so that anyone passing by could see inside. Elle tried to cover herself, but Lucile wouldn’t allow it.

“Please, not here. There are people on the streets.”

“Nonsense. No one is looking inside, and if they do, there’s nothing more natural than a mother changing her baby.”

Lucile removed the soaked diaper, cleaned Elle’s private parts, and placed a new diaper on her.

“No poopy messes yet. No worries. It will happen soon enough. Maybe even sooner, considering all the yummy-yummy milk my baby had.”

“Poopy messes?” asked Elle, but Lucile was gone before she could inquire further.

A few minutes passed. Elle’s tummy gave her a signal, growling in an all-too-familiar way. She had not make her morning's poop yet. A ritual she performed every single morning right after having her breakfast. She shook it off. She had peed herself already. There was no way she was going to humiliate herself further that day. But she began sweating cold, her tummy grumbling even louder now.

It was a small, wet fart at first. Something imperceptible. Perhaps she was reacting to her sister's milk.

Her body was definitely not happy with what she had done. She let out another fart. And another one, and another one. And then she felt a semi-liquid mess escape her butthole. Something warm spread all over her diaper, reaching her crotch and private parts. It happened so fast she couldn't really control herself, and when she felt it reach her vagina, she couldn't help but let out a soft moan.

"Are you okay?" asked Lucile, who was standing a few feet away from her sister.

Elle shook her head.

The mess was still pouring from her hole, and she didn't know what to do or how to stop it. So she did the thing every baby does when they have an accident. She began crying desperately and shamefully.

And then the mess stopped, but her cries didn't.

"Did you have an accident?"

But Elle didn't answer.

"It's okay, I'll get you clean," said Lucile, but right before she could get to her sister, another round of cries coming from the second floor echoed through the house, "I think the other baby's up. I think she might need a change, too. Might as well do you both now."

"No. Please, I don't want her to see me like this."

"Well, that's not up to you."

"But…"

"One more but, and I swear you'll spend the rest of the day in that messy diaper of yours. Understood?"

Elle nodded, tears falling from her eyes.

"Good, now let me bring your sister here so that I can get you both clean," said Lucile, sniffing the air in the living room, "Might have to start with you, you little stinker."

And she was gone, leaving Elle sitting on the couch. Her mess spread all over her crotch, tears falling down her eyes, and that pleasant feeling growing in her most private parts, making her blush. Was her sister really going to change her messy diaper right next to her daughter? Was this going to be the most humiliating moment of the weekend? Or had her sister planned something even more terrible?

Minutes passed, and nothing.

Elle just sat there in her own mess, feeling the warm semi-liquid poop against her crotch and every inch of her diapered skin. She couldn't believe the diaper was able to hold so much; had it been slightly smaller, it would've already been overflown, and her mess would be everywhere.

And then she heard it.

Steps came from the stairs, and a loud sob she recognized immediately. The sound of her daughter ready to be fed, changed, and loved and the motherly urge to stop pretending to be a baby forced her on her feet. She couldn't keep doing it. She was a mother, and she had a responsibility. It didn't matter what her sister said. There was no way she could be overpowered. She would not let Lucile spank her back into babyhood. She was an adult and a mother, and she had had enough. She would rush to the bathroom, clean herself, and go back to her life.

With determination in her eyes, she started walking. If it had been difficult before, it was almost impossible now. The diaper was bigger and heavier, and every step felt unsteady and hard, so she had to walk close to the walls to prevent falling on her ass again.

That's when she saw them.

Her sister was standing right at the bottom of the stairs with Camille in her arms. They both were looking at her like it was some sort of bizarre spectacle. Which, Elle thought, was understandable. Where else had they seen a woman her age wearing nothing but a diaper? A wet and messy one, so full it spread her legs apart, preventing her from walking like a normal adult.

"I don't recall giving you permission to leave the couch."

"It's over, Lu," she said, trying to believe her own words, "I can't do this. I'm her mother, and I'm your big sister, and this needs to stop. I'll find a better way to connect with Camille."

"Why's Mommy in a diapy?" asked her daughter, amused by the situation, "Is Mommy baby like me?"

"No, sweety. It's just a little prank," said Elle, "Right, Sis?"

"Camille, remember I told you I had a surprise for you?" asked Lucile.

Camille nodded.

"Well, this weekend, Mommy will actually be your little sister. And she'll play with you and be your friend."

"Really?"

"No! That's not true, my love. Your aunt is not feeling well, and she needs to leave now!"

Lucile giggled, "You see, just like you pretend to be a grown-up sometimes, your Mommy is pretending too. But we must help her."

"How?" asked Camille, excited.

"By treating her the way she deserves to be treated. Like a little baby girl. Even more little than you."

Camille giggled, "Can I be Mommy's Mommy?"

"No, I will be your Mommy. But you can be her big sister."

Camille nodded.

Elle was frozen in her place. How dare Lucile shame her like that in front of her daughter? How dare she try to force her into doing something she didn't want? And something came over her. A rage and anger she had never felt before. She needed to confront her sister and reclaim her motherhood. She needed to reclaim her adulthood. She needed to do something before it was gone.

And so she rushed to her sister, failing to be menacing while being stuck in a messy diaper.

Lucile chuckled, "What are you doing?"

Elle didn't answer; she rushed to get her daughter from her sister's arms. But Lucile was faster, and with one simple and gentle push, Elle was back on the floor. Her own mess spread even further around her crotch. The arousal and discomfort were too much for the once proud mother.

All the emotions. All the shame and humiliation. The discomfort of sitting in her own mess while her daughter watched as if it was a TV show. She couldn't cope with it. And she cried desperately. She had lost count of how many times she’d cried that morning. It didn’t matter anymore. She let it all out.

"Oh, don't cry, baby," said Lucile, "Not yet. I'm about to give you something to cry about."

And Elle let out another stream of urine, hoping her diaper would hold it all, and she kept crying.

Chapter 3

Elle’s Regression Begins

Elle cried her heart out, her thumb on her mouth. It was as if sucking it gave her some sort of comfort. Though she didn't know how it had gotten there. Most of the last few minutes were a blur. She remembered her daughter laughing at her. She remembered her younger sister giggling at her shame. And then nothing. One thing was for sure. Her diaper was full, and it needed to be changed.

"Come with us, Camille," said Lucile, picking up Elle in her arms, "You need to see what's about to happen."

"What's gonna appen?" asked Elle between sobs.

"I'm gonna spank adulthood out of you. Just like I promised."

"No, pwease!"

"Mommy's gonna get spanked!" said Camille, giggling still.

Elle couldn't free herself from her sister's grip. Lucile seemed to not think about what it could mean for Camille to see her mother being spanked in a messy diapered. She might as well lobotomize her. There was no way Camille would ever see Elle as her mother again. She didn't sign up for this. It wasn't what they agreed upon. What would Steve say if he saw her like this? Would he even want her as a wife ever again?

"Ready, sis?" asked Lucile, whispering in her ears, "I hope you'll learn your lesson so that we can enjoy the rest of the weekend."

"Pwease!"

Lucile sat on the couch again with Elle on her lap, "This will hurt me more than it'll hurt you."

Elle froze.

Those were her mom's words whenever she disciplined Elle or Lucile. However, it was usually the older sister who got that treatment. For a second, Elle saw her mother in Lucile's eyes, making her shiver. Their mother was a severe woman with an unusual lack of love for her kids. But Elle had always had Lucile. Her younger sister had been more emotionally stronger than she ever was.

SMACK!

The first hit against her messy diaper just pressed every inch of poop even further against her crotch. It was a horrible feeling of discomfort and humiliation. And Elle didn't know what to do but avoid her daughter's gaze. So she closed her eyes.

SMACK! SMACK! SMACK!

Tears began falling down her eyes, but it wasn't because of the pain. No. It was because her daughter was sitting right in front of her, giggling as if seeing her own mother being spanked was the most entertaining thing in the world. This wasn't for pain. No.

SMACK! SMACK! SMACK!

"Pwease stop!"

SMACK! SMACK! SMACK!

Elle was a sobbing mess now. Her mind couldn't cope with the idea of being an adult, a mother, and being spanked while in a messy diaper. It was like something breaking inside of her.

SMACK! SMACK! SMACK!

"Mommy, pwease. I'm sowy!"

And then it stopped.

"Did you call me Mommy?" asked Lucile.

Elle nodded.

Lucile smiled devilishly.

"Very well, I think you've learned your lesson."

Elle had her thumb in her mouth and was sobbing like a little girl.

"I think it's time to change my two little girls. Because one of you is very stinky right now," said Lucile, helping Elle into a changing mat in the middle of the living room.

"Mommy's stinky. I'm not!" said Camille.

"That's correct."

Elle just stayed there, hoping this was all a bad dream.

But if it was a bad dream, it just wasn't over yet. Lucile placed a changing mat in the middle of the living room and brought every supply needed to change a baby's diaper. Thought the diapers themselves were huge, even thicker than the messy one Elle was wearing already.

"Camille, you come first. I've been told you wanna start potty training like a big girl, right?"

Camille nodded.

"Then I think we can start using pull-ups during the day. What do you think?"

Camille nodded even more enthusiastically.

"Are you ready to be a big girl?"

“Yes!”

"Good," said Lucile, helping her niece into a pull-up after cleaning her, "Now it's time for the new baby of the house."

Elle didn't move. Didn't say anything. She sat there, waiting, sucking her pacifier, terrified of her own younger sister. Ashamed about what had happened in front of her own daughter. She was still sobbing, and the more she sobbed, the more she sucked on her thumb.

"Why don't you watch some TV while I deal with your baby sister?" Asked Lucile to her niece.

Camille protested; she wanted to stay. But Lucille ordered her to do so, and the younger in the room obeyed. After all, Lucille was convincing. She explained that big girls obeyed their mommies. And if Camille wanted to be a big girl, she needed to obey and set an example for her younger baby sister. Lucille helped Camille into the entertainment room, playing a movie she loved, Sing.

"Now that we are alone," said Lucille, returning to the living room, "Are you ready to start the weekend?"

Elle didn't say anything, but her body answered for her. A loud, wet fart and more poop found its way into the already full diaper.

"I guess that's one way to answer."

The change was quick and methodical. There was more poop inside the diaper than Elle had ever seen. And the smell alone was terrible. Something Lucille didn't miss, and Elle earned herself the nickname of Little Stinker. Once the diaper was removed and Elle's private parts were clean again, her younger sister sealed her back into another diaper. This one was wider and thicker, making it impossible for Elle to move around freely.

"Relax, Little Stinker," said Lucille, smiling.

But Elle couldn't relax.

"I know what to do with you.”

It happened quickly. Lucille lifted Elle's onesie, revealing her slightly chubby tummy, and without hesitation, she blew raspberries on it. She couldn't control herself, so she giggled like her daughter when Elle had blown them on her. It didn't stop. Lucille kept blowing raspberry after raspberry until Elle was crying and giggling simultaneously. For a second, she forgot why she was so sad and enjoyed the attention. But once it was over, shame invaded her again.

"Let's go get your big sister, and the three of us can watch a movie."

It wasn't a question. It was an imposition, and Elle had no say in the matter, so Lucille just picked her up and carried her to the entertainment room, where Camille was watching and signing to a kid's movie. Gently and carefully, the younger sister placed her older sister on the floor right next to her niece. The contrast between them both almost made Lucille chuckle. But she fought it back. After all, here, there was a mother wearing a thick, quite-visible diaper, sucking her thumb, blushing, and behaving just like a little girl. Next to her was a real little girl, her daughter. And she wasn't wearing diapers anymore. She was acting tougher. More mature.

This is going to be fun, thought Camille.

Elle couldn't look at her daughter. Not after what had happened. The mother sat there, sucking her thumb, hoping this weekend would be over now. She didn't notice how or when. Perhaps it was just because the movie was fun and colorful, but she got lost in it. So lost that she didn't notice she had peed her diaper a couple of times while she giggled at the cute old lizard and the nice koala. When the movie was over, like a big girl, Camille asked for the potty. It's such a big accomplishment. At least, that's what Lucille said. Elle, on the other hand, realized she had peed herself. Seeing her daughter master potty training while her control over her bladder and bowels deteriorated just served to push the older woman in the house to a tantrum.

"Calm down," said Camille while changing her younger sister's soaked diaper, "It's okay. Babies use their diapers. That's what they are made for."

"I'm not a baby. I don't need diapers!”

"Don't you? Then why did you pee yourself? And not for the first time, mind you."

"It's your fault. You did this to me.”

“I did this to you? Really? That’s your excuse?”

“It’s not an excuse!”

"You're cranky,” said Lucile, smiling from ear to ear, “You've already eaten. Your diaper is clean now. Then that means only one thing."

Elle was confused at her sister's words. They had nothing to do with what they were talking about, but it became clearer when Lucille took her to Camille's nursery. A little girl's heaven. Pink and bright, with stuffed animals everywhere and Disney princesses decorating the walls.

“You need a nap.”

"I don't need a nap!"

"Do you want another spanking?"

Elle froze.

"Nuh," she said, with her thumb back in her mouth, "No, pwease."

Lucille laughed as she turned off the light and closed the door, leaving Elle alone with her thoughts. The mother didn't want to go to sleep. She wasn't tired. She couldn't take it anymore. But if she truly disliked her new position, why was she still sucking her thumb? It was comforting, she argued to herself. She needed some comfort. Why did you get aroused by your dirty diaper? I haven't had sex in a while, she said to herself, blushing. Minutes passed, and thoughts became distant. Her sucking became rhythmical. And her heavy eyelids closed.

Chapter 4

The Diapered Mother

The dream took her to a country club.

It was a familiar sight of a beautiful day at the park, but something unfamiliar was happening around her. It was a picnic, perhaps a BBQ—something one would attend on a Fourth of July evening. For Elle, however, it was a surreal experience.

She was diapered.

That part was obvious to her. She couldn't even close her legs enough to stand up properly. She had no clue when, how, or what had happened, but she was diapered. Sucking her pacifier and playing with her dolls right in front of dozens of her friends and family members. She could see her daughter playing with the bigger girls and her husband talking business with the other men. And her sister, Lucile, looking rather dazzling, chuckling with the other wives — a glass of wine in one hand and a cigarette in the other.

Everyone seemed happy and delighted at the perfect day, and no one seemed to care about the diapered woman in her thirties, sitting on the ground, dressed like the perfect toddler princess.

In fact, many of her old friends were there. They were surrounding her with compliments and kisses and care, and she wondered if it was all real or not.

"Looks like someone's made a stinky present for her mommy," said a young girl, kneeling right next to Elle, lifting her dress and checking the state of her diaper.

Elle blushed.

"Right on time," said Lucile, getting closer to them.

"Is it okay if we help?" asked Mindy, the Queen Bee of the country club.

Lucile nodded, uncared about Elle's protests. She didn't want others to see her shame. But then again, babies felt no shame. And those conflicting thoughts kept spiraling in her head as she was led away from the BBQ and into a family's bathroom not too far from where they were. There was a changing table, maybe not big enough for Elle, but that didn't stop Lucile. She placed her older sister right on top of it, allowing Mindy to witness the messy diaper the older woman wore.

Mindy giggled softly and approached Elle, "I always knew you were nothing but a dumb little baby pretending to be a woman."

"That's right, Elle here is nothing but a dumb baby. Aren't you, sweetie?" asked Lucile.

Elle's embarrassment escalated even further when her sister opened the tapes of her diaper, revealing her messy, hairless crotch. Elle closed her eyes, avoiding eye contact, but when she opened them, she wasn't in the bathroom anymore. She was outside. In the picnic area, everyone looking at her getting her diaper changed.

Suddenly, the place filled with laughter and smirks coming from her peers, who once looked upon her as a respectable woman. Now, they saw her as nothing more than the dumb baby she knew she was deep inside – a source of amusement.

And then she woke up.

She was still diapered but in her own bed. And the events of the previous day came rushing back, flooding her brain with humiliation and shame. Her hands found their way to her padded crotch to realize she had wet herself already. She tried to stand up, but before she could, she was surprised by someone walking into the room.

"So you're awake?"

"Mhm, yes," she replied, sounding uncertain and embarrassed.

"Did you sleep okay?"

Elle shook her head. The nightmare was still present in her mind. She just didn't know what to do. She couldn't tell her sister about it. It was preposterous.

"Oh, look at that, someone's wet."

Elle blushed. She hadn't even noticed.

"What are you doing?"

"What do you think I'm doing?" asked Lucile, removing the tapes from her sister's diaper.

"You don't have to. I can change myself."

"You can now? I don't think you understand your new position in this house."

"What do you mean?"

But Lucile didn't answer. She just smiled devilishly.

She gently picked Elle up, lifting her skirt to expose her soaked diaper. The younger sister smiled slightly, enjoying that she could easily carry her older sibling. Elle remained silent throughout the process, feeling increasingly humiliated as her younger sister cleaned her. She should hated it. She should have fought back, but she didn't. If anything, the more she was treated like a dumb toddler, the more she liked it.

"This is so fun," said Lucile as she helped her sister up, "You know Camille just made it to the potty while you were taking a nap. I think, at this speed, she's going to be out of diapers before you. Do you think she'll mind changing you in a few years when she is older?" joked Lucille as she led Elle outside the bedroom.

Elle blushed as the thought of her daughter gaining big girl panties while she was downgraded to diapers flooded her mind. Would her husband help her, or would he reject her? And what did her sister gain from this?

"Can I ask you something?" asked Elle, still ashamed of her current situation and not really thinking about the question she wanted to ask.

"Shoot," said Lucile.

"Why are you doing this?"

Lucile smiled, "It's a long answer, but the short version is that I envied you. I dedicated myself to my career and have no family of my own. You barely do anything, and yet, you get everything. Why?"

Her younger sister's demeanor shifted and turned dark, "Why can't I have it? The last few hours had been perfect for me. And if you are honest with yourself, they've been perfect for you too."

Elle shook her head.

"Are you going to deny you didn't enjoy it? I know you, sis. You have the perfect life, but you don't enjoy it because you never really grew up. You enjoy this. Being treated like a dumb little baby is probably the best feeling, right? I see it in your eye. I'm good at my job, sis. Why don't you admit?"

Elle looked away.

If she was honest with herself, her sister was right.

She did enjoy being treated like a baby. She loved having someone else take care of her needs. Even though she despised it, she craved the control she lacked during those moments. Lucile dressed her, bathed her, and took her for a nap. It all felt so much better than having to be a mother, a wife, an adult. But she was those things.

"But I'm an adult," said Elle, fighting back the urge to be held by her younger sister.

"No, sis. You aren't. Today and tomorrow, you will be nothing but a baby. And I suggest you accept that. It'll make everything easier for you. By the end of the weekend, you can go back to your old life if you want to."

"If I want to?"

"The choice is yours. I'll ask you tomorrow night what you want to do."

"What if I choose this?" asked Elle, touching her diapered crotch.

"Then things will change a lot around here. But you will like that, won't you?"

Elle didn't answer. She just let her sister lead her through the corridors and passages of the house until they were back in the living room.

"Where's Camille?" asked Elle.

"She's napping. If she manages to wake up dry, she'll move up to pull-ups during the night. Isn't that funny? You wanted to potty-train your daughter. And now, perhaps in the future, she might end up changing your diapers."

Lucile sat Elle on her lap. Her diapered crotch was right against Lucile's bare skin. She had taken her older sister through a journey, and now she needed to be patient. If she pushed too far too fast, it would all come crumbling down. If she played it right, by the end of the weekend, she would have her sister's life - a husband, a daughter, two daughters, though one would stay a baby forever.

"Are you hungry?" asked Lucile.

Elle nodded.

With a swift and gentle movement, Lucile removed her shirt, revealing her two massive breasts and the delicious nipples Elle had tasted earlier.

Silence reigned in the living room as Lucile gently pulled Elle's lips against her nipple. The older sister didn't know what to do. The shock of it had broken her brain activity. So something primal took charge. A need, an instinct. She began sucking and sucking. It was heaven, just like it had been that morning, and she wondered if she could ever live without it again.

Elle nursed on her sister's breast, feeling the warmth flowing through her veins, making her feel safe and secure. She couldn't even imagine leaving this behind, but she knew she must. This wasn't her normal life.

"Isn't this better?" asked Lucile, breaking the silence, her hand brushing over Elle's shoulder.

Elle paid no attention to her sister's words. Her mind and body were concentrating on just one thing: Sucking. She sucked on her younger sister's breast as if her life depended on it. The sweet and tasty milk flowed down her throat, creating a craving for a life she had lost so long ago. If this was her new self, she was ready to give up. Ready to give it all up and become her younger sister's baby. Her social circle would know, and she wouldn't care, and her husband would not be her husband again. But oddly, she felt like it was the right thing to do.

The rest of the night passed by in the blink of an eye, and Elle couldn't believe how good it felt. She colored with her daughter. They watched Mulan together. They played house while Lucile ordered pizza for dinner. The only problem was, instead of Elle being the Mommy, she was the baby. And Camille took her job quite seriously.

"Baby Mommy's wet!" she said as they played.

"I'm not!"

But when Elle looked down, she noticed her daughter was right.

"Pizza's here!" said Lucile.

"Yay!" said Camille.

Elle said nothing. She had not realized she had peed herself. Her diaper was soaking wet. It wasn't the usual slight tinkle she was used to because of giving birth. No. This was full-on incontinence.

They ate. Mostly Lucile and Camille. Elle was too confused and upset to enjoy her meal. Even when Camille did her best to make eating fun for her. Here comes the plane, she would say, and Lucile would giggle.

"It's time to say goodnight," said Lucile firmly after they were done.

And in response, Elle yawned loudly. She hadn't known how tired she actually was after spending most of the day from one humiliating scenario to another to the point she felt no shame anymore about being paraded in diapers around her own house in front of her daughter.

"Okay," she murmured, almost disoriented by the sudden transition from a helpless infant to a tired grown woman.

As she stood up, a wave of exhaustion swept over her. But before she could even take a step, her sister grabbed her and carried her away as if she were indeed an infant. They reached the bedroom where the once-mature mother used to sleep with her husband. Her younger sister tucked her in, providing a pacifier to help her sleep better. Elle accepted the gift and immediately began sucking. Her eyelids grew heavier, and her eyes grew tired, and her thoughts faded away as she sucked.

Chapter 5

Elle’s Potty Accident Outside

Elle woke up.

She was still diapered but in her own bed. The events of the previous day came rushing back, flooding her brain with images of humiliation and shame. She recalled being spanked by her younger sister. She recalled being diapered and messing that diaper, being bathed by her younger sister, and so much more. Her hands reached her padded crotch to realize she had wet herself again. Why was this happening?

She tried to stand up, but before she could, she was surprised by someone walking into the room.

"You're awake," said Lucile, holding a fresh diaper in her hand, "Good."

Elle nodded.

"Sleep okay?"

Elle nodded again. She wasn't about to tell her sister what she dreamed.

"Ready for your last day as a baby?"

Elle nodded again, hesitant. There was no way she was going to choose a life of diaper changes, breastfeeding, and silly toys instead of her real life. The life of a wealthy woman with a loving husband and a daughter. But then again, was it really such a good life? People she knew considered her a gold digger who was past her prime. She didn't have that many friends. And her husband wasn't happy with her. Her daughter seemed to prefer her as a baby sister rather than a mother. Did she really have a reason to remain an adult?

"It's good you're ready 'cause we are going out today."

"Out? Am I not going to be a baby today?"

Lucile giggled, "Of course you will. That's a silly question."

"But-- I'm no...What if people see?"

"What if they do?" asked Lucile as she removed her older sister's wet diaper, "We are going to the park. Just the three of us. Camille wanted to go out, so that's the plan. We might stop by McDonald's on our way back. You'll get a happy meal."

"I don't...I can't go out like this."

Elle whined, feeling self-conscious in her thick plastic pants and bright-colored onesie. "You'll wear something comfy, don't worry."

Comfort wasn't Elle's worry. But, as her sister had made perfectly clear, she had no say in the matter.

That morning, she was given again the pleasure of tasting her younger sister's milk. It was heaven like it had been the day before. Camille woke up an hour later, and together, they played after her daughter was fed. Thirty minutes later, she was given a bath and put on a fresh diaper. A pretty dress that was more fitted for a toddler than someone in her thirties was Lucile's choice for her. Elle couldn't really complain. She didn't want another spanking. Not in front of Camille. But the dress did very little to hide her thick, printed diaper.

"We are all ready," Lucile said, and they were on their way.

Walking down the street, holding her sister's hand while wearing a diaper so thick it was difficult to stay on foot, was the most adrenaline she had felt in a while. Was something wrong with her? She was an adult and a mother. And here she was, getting aroused with every step she took.

Finally, they made it to the car, and Elle was placed on an oversized seat for toddlers.

"Is this really necessary?"

"Sorry? I thought I heard an adult."

Elle sucked her thumb in submission to her sister.

"You look so cute," said Lucile.

Elle blushed, avoiding eye contact, knowing the entire world was about to find out about her current situation.

Once Camille was sat on her seat and Lucile had packed the diaper bag, they were on their way. During the driving, Elle kept wishing the park would be empty, that somehow, everyone had decided to stay at home and not go out. That something would happen to the car, so they wouldn't make it —Nothing serious, of course.

But as she thought about the many possibilities, they made it to the park in less than ten minutes.

"It's time to play," said Lucile.

"Yay!" said Camille.

Elle was surprised by the amount of kids and parents around. Most surprisingly, no one seemed to care about the woman in her thirties with the oversized diaper barely covered by her toddler dress. If anything, some kids just seemed to accept her as one of their own. That was even more obvious when Camille grabbed her hand to lead her to the playground.

"Come on," her daughter said, "Let's go play!"

"Go on," said Lucile, "I'll be looking after you from here."

For almost an hour, they played. She played with the other kids and her daughter and, for a second, there was nothing in her mind but her new role as a baby.

Then suddenly, amidst the children's laughter and screams, her senses returned.

"Eww. she farted."

She heard one of the kids say. And it was true. She had stopped playing, squatted right there, and was now pushing. If it had not been for their words, she would've done it without even realizing it. And when she realized what was going on, she couldn't stop sobbing as the mess spread around her diapered crotch. She sat there, crumpled, surrounded by her fellow kiddos who only moments ago thought her their friend. They played, oblivious to her growing panic. Elle looked around for her Mommy, but she was nowhere in sight.

A couple of mothers noticed the situation and came over to lend a hand. One offered her a change of clothes, while another suggested calling her Mommy. They didn't even blink an eye at the bizarre situation. Maybe they thought she was just a special kid with special needs. Elle's sobbing intensified as the attention she received from both her peers and the public grew out of proportion. Soon, cameras started flashing, recording the disgraceful spectacle unfolding under the playground equipment.

"It's okay, I'll call Mommy," said Camille, and the fact her daughter thought of Lucile as her mother stabbed her right in the chest. She continued sobbing as her thumb found its way back into her mouth. Perhaps this was her new life. A new reality. Perhaps Lucile was right. Elle just wasn't designed to be a mother, an adult, or a wife. She was meant to be a baby.

Chapter 6

Elle’s Decision

Ten minutes after Elle had messed herself, Lucile returned with Camille by the hand. The younger sister apologized to the other mothers for the spectacle. She assured them she would never leave the babies alone again. She just had an emergency call from her husband and needed to settle some things.

"It's okay," said one of the mothers, "We understand. Our husbands are also a piece of work."

"Yeah," said another, "Your little girl might've just gotten scared."

"Does she have special needs?" asked another one.

"She does," said Lucile, smiling as she led Elle away from the playground and the crowd.

Elle was sobbing the entire time, feeling the mess inside her diaper spreading around her skin with every step. It was not the arousing situation it had been the day before. This time, the humiliation was greater, to the point that she just wanted to crawl into a hole in the ground and disappear. And what husband was Lucile talking about? She wasn't married. She also wasn't her Mommy, nor Camille's.

"I think you are getting too used to your diapers, aren't you, baby girl?" asked Lucile teasingly, "Good thing your big sister was around to help."

"I helped baby mommy, Mommy!" said Camille.

Elle blushed, sobbing, but before she could complain, her sister shoved a pacifier back into her mouth. "You did help her. But she's not your Mommy, is she?"

"No?"

"Do mommies wear diapers?"

Camille shook her head.

"Do they go potty in their diapers?"

Camille chuckled and shook her head.

"Then?"

"She's baby!"

"Correct. She's your new baby sister. At least until she stops messing herself."

Elle wanted to protest, but she knew better than to argue with her little sister. As much as she hated being paraded around like a dumb toddler, she couldn't bear another round of spanking in her messy diaper. Could she? No. What if she enjoyed it again? And everyone found out she actually liked her new role. Everyone could find out she was a deviant, a freak who enjoyed wearing and using diapers. As they entered the small public family bathroom, Lucile removed Elle's dress, exposing her soggy and messy diaper.

"Let's do this fast."

With expert fingers, Lucile cleaned the soiled areas of Elle's diaper, wincing slightly as her sister squirmed and cried softly. Elle needed to get used to it. This was her life, and after her call with Steve, there was no coming back for little Elle. He had been taken aback when he received the photos of his wife wearing nothing but a diaper. The video she had made of Elle being breastfed. And the diaper change she had received after.

"Don't move. Good girl. You're getting better at this?"

"At receiving diaper changies?"

"At being a baby. I guess you just needed to stop pretending you were an adult."

Elle wanted to die. Not just because of the humiliation but because of how it made her feel. When she was locked back into a fresh diaper, she had no more tears to cry. Her eyes were dry, she was thirsty, and the image of her sister's breast came to mind.

"It's almost mealtime," said Lucile, "Who's a hungry baby?"

"Me!" said Camille.

"But sugar, you aren't a baby anymore. Right? You're a big sister now."

"Oh, right. Yes. I'm a big girl!"

Lucile's gaze turned to her older sister, still lying over the changing table. "I know what you'd like to eat. But I did promise your big sister she would choose."

"MacDonald's!" said Camille.

"But..." said Elle, "I'm hungwy."

Lucile knew what she meant, but she did promise Camille, "I think a happy meal for my two girls should be enough."

Elle nodded, though reluctantly. She wanted to return home, sit on her sister's lap, and enjoy her sweet milk. It was her last day as a baby. Why not enjoy the good parts as much as she could? Alas, she couldn't. So they reached the car, ignoring the staring looks of bystanders.

With Elle in the passenger seat, they drove to McDonald's, seething with frustration at her predicament. In her head, all she could see was the taste of her sister's breast milk filling her lips - an addiction that haunted her ever since her first encounter. On top of that, she felt dirty, smelly, covered in the evidence of her urges, yet still unfulfilled. She didn't even notice when Lucile carried her from the car into the restaurant, placing her on one of the high chairs, which she was admittedly too big to fit in. It didn't stop her sister, though. At first, she thought people would complain. Would say something about the madness of the situation, but nothing happened.

Camille happily played with a Happy Meal box in the backseat, oblivious to her mother's predicament.

"What toy did you get?" asked Camille to her mother.

Elle did as told.

"That's like you! It's baby Peach!"

"I'm not a baby. I'm your mother."

Camille giggled, "Mommies don't wear diapers. Mommies don't sit on high chairs or poop themselves."

She was right. And she knew it. She had resisted these feelings, but to no avail – the desire to act like a helpless infant, the craving for something that only her sister could provide. Was she indeed not a mother anymore? Was she indeed just another baby? Now, faced with her reality, surrounded by strangers staring at her plump bottom poking out of a wet diaper, Elle realized it was futile trying to deny it any longer. This was the life she had chosen...or rather, let it choose her.

The right back home was as swift as fast as Elle's potty accident. Camille fell asleep right before they reached home, so Lucile carried her inside before coming back for Elle, who, by then, had already soaked her diaper again and had been seen by at least ten more people.

"Did you have fun today?" asked Lucile.

Surprisingly, she did. At least until she disgraced herself in front of dozens of people in the park.

"Do you want Mommy's milk one last time?"

"One last time?"

"Well, unless you choose to stay like this forever, I'm not breastfeeding you again after this."

"Oh, right," said Elle, pretending she was not devastated at the news, "I guess it's the end of the experiment."

"Is that your decision?"

Elle shook her head.

"Are you saying you want to be a baby again? What about Steve?"

"I don't know, I'm not sure. I... It's too much," she said, and her watery eyes closed as she buried her face against her sister's chest, "I don't know what to do. Am I a freak?"

Her sister held her tight, the same way a mother would do. She said nothing, allowing Elle to vent her emotions as she cried, shook, and peed herself again and again.

"I think we know what's going to happen now."

"What?" asked Elle.

And Lucile opened her blouse, revealing her perfect breasts, and Elle knew instinctively what to do. She got closer, almost rushing, until her lips touched her younger sister's nipples. And she sucked and sucked and sucked, receiving the sweet nectar of her milk.

"Steve won't be happy about this," said Lucile, "But I'll deal with it. Your life is going to change a lot. But I'll protect you. Always. So long as you submit now. If you have anything to say. Say it now. Fight for your adulthood right now or say goodbye to it."

Elle wanted to do it. She wanted to fight back but didn't want to stop sucking. The train had left the station, and so did her adulthood. Her addiction to her sister's milk proved stronger, and as she closed her eyes and continued sucking, Lucile knew she had won. Elle's life as an adult, as an older sister, as a mother, as a wife, it was all over now.

Chapter 7

Elle’s New Life

Steve arrived home after a long weekend away.

He only wanted to relax and enjoy some time with his family. Things had not been good with his wife lately. If anything, things were worsening every day, and he couldn't help but wish Elle would just ask him for the divorce. They had had an amazing time together, but lately, Elle had been behaving like a spoiled brat. He couldn't take the stress of work and then come back home for more stress.

It was too much.

And then he got a weird phone call from his sister-in-law. It was ridiculous. Elle apparently had had a mental breakdown and was no longer able to be a mother. She wasn't in a condition to be a mother even before the mental breakdown. But what she said after was even more preposterous. I gotta go. Elle needs a diaper change. Those words kept replaying in his mind rent-free. Elle needs a diaper change. Why?

He closed in on the front door, breathing in and out, hoping to enjoy some tranquility before venturing back home. As he opened the door, determined to get things right in his life and find out what his sister-in-law meant, he was met by a bizarre scene.

There sat Elle, dressed in a dress that did nothing to hide her diaper, playing with dolls, not even realizing her husband was home. She seemed lost in a trance, like a little girl. A real one.

"Daddy!"

He heard Camille say as his daughter rushed to greet him.

"Sweetie," he said, holding his daughter in his arms, still in shock at the bizarre scene he had entered.

"Steve!" said Lucile, "So glad you're here. Do you mind looking after Elle while I give Camille a shower?"

"Looking after? What's going on here?" asked Steve, not sure if he had processed what he was seeing yet, "Elle! Stand up now. Is this a prank? What are you doing?"

"Don't talk to your baby like that," said Lucile, "You're going to scare her off."

"Scare her?"

She was right. When Steve turned to see his wife, her eyes were full of fear and shame. She was pleading with him without saying a word, and he understood.

"I'll look after her."

"Good," said Lucile, kissing Steve on the cheek, "I'll be back, and I can explain everything once Camille is put down for a nap."

"I'm not sleepy! And I wanna be with Daddy!"

"Be a good example to your baby sister and behave like a big girl."

"Okay, Mommy."

Mommy? Baby Sister? Were they talking about Elle? What was going on? Steve had so many questions, and every possible conclusion was more ridiculous than the previous one. Camille and Lucile disappeared upstairs as he kept going through the different possibilities. It was just Steve and his wife. At least what was left of his wife. The once lazy and submissive mother was now reduced to a diaper-wearing toddler, shy, cute, and unable to maintain eye contact with him.

"What happened to you?"

"If Mommy hears me talk, she punishes me."

"Did she do this to you?"

Elle nodded, blushing, and then shook her head.

"Did she or did she not?"

"I asked for it," she said, and her voice trembled slightly as pee found its way into her diaper, "I'm sowwy."

"Sowwy? You ask to become a baby? Your younger sister's baby? What about your daughter? Our family? What about me? Did you stop to think about anyone else but you?"

Steve was furious now, and the sight of his wife in her toddler attire did nothing to appease his rage. But he calmed himself down. He had never raised his voice to her. Not even when she was being a brat. And with Elle, being a brat was more like a default.

"Pwease, Daddy. No get mads at me."

"Daddy?"

Elle was sobbing now in front of her husband. He was right. She had thought about no one but her most of her life. And when she decided to be a baby again, she thought of nothing but her own pleasure. This time, though, she took Camille and him into consideration. They were going to be happier if she wasn't in the picture as a mother or a wife. Lucile could take on those roles. She was always better at being an adult - at being a woman.

"Camille is our responsibility, Elle," Steve said firmly, pulling her attention to the present moment. "We need to discuss how this will affect our lives moving forward." His calm demeanor contrasted sharply with the storm raging inside him.

Elle sniffled, trying hard to regain control of her tears. "Mommy says we should start right away – You and her should sleep together and be Mommy and Daddy, and I be baby and Camille's baby sister. And...."

Steve looked doubtful. "Sleep together... Are you serious?"

Elle blushed. She was asking her husband to sleep with someone else. And the worst part of it all, she was enjoying it. Her hairless crotch, tingling with a rush of excitement against her flooded diaper, craved for release. But she fought it. It was her last time. The last moment of adulthood, she had to muster before becoming the baby she was determined to be.

"I wants this," she said, blushing even redder.

"What about your daughter? What about me?"

"It would be the best for all of us. You get a good wife. A real wife. Camille gets a mother. A good one. And I get to," she paused, blushing again, "I get to live life the way I was meant to."

It didn't take much longer for Steve to accept the new status quo in his house. His anger gave way to resignation and, finally, curiosity. It was fascinating watching his wife revert to a babylike state – a mere shell of who she used to be. Strangely enough, something within him felt drawn to this helpless creature before him. He realized, albeit reluctantly, that it was the best for everyone.

Camille had never been happier. Taking upon the role of a big sister, she finished potty training within a few weeks—something Steven and Lucile celebrated with a big cake.

"How does it feel?" asked Lucile as she changed Elle's diaper that morning, "That your daughter is already potty trained while you have been regressed back to diapers?"

Elle blushed as her younger sister exposed her hairless parts. She didn't answer. She only sucked on her thumb as she enjoyed the degradation and humiliation of knowing her own baby daughter was now more mature than she was. The mere thought of it sent shivers through her body, culminating in an intense climax as her younger sister cleaned her messy crotch.

"Look at you. You've come a long way," said Lucile.

Elle blushed as her body shivered.

"You're so pathetic. A grown-up woman, living her life as an oversized toddler."

Those mean words echoed in Elle's mind. She was indeed a grown-up woman. Yet, she had been acting like a baby every day, all day, since that weekend. Since she made the mistake of trusting her younger sister. Acting, perhaps, wasn't the right word. It wasn't an act. Not anymore. Not for Elle. It was who she really was. It didn't matter if her friends, family, and even enemies had seen her mess herself multiple times by now.

She was happy being a baby.

And as her sister taped another diaper around her crotch and she continued sucking her thumb, Elle was ready for her midday nap. She was ready to meet her new babysitter. Mommy had even found another woman she could have playdates with. A woman who had been regressed into babyhood just like her. She could have a friend. And then her Mommy picked her up, sitting her on her lap, offering Elle the big, round nipples she had come to love.

This was heaven for Elle. No longer a mother. She was now a baby.
