A Mother’s Mistake (Patreon)

Part One

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 two years old, and things had not been good lately between them. Elle felt it was because she couldn’t connect with her no matter what she tried. Whether it was breastfeeding, playing, napping, or watching cartoons, nothing seemed to make things work.

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.

“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 being, can you?”

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

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

“What would being helpless look like?”

“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 you get people agree to it?”

Lucile chuckled, “Well, because it works. That’s why they pay so much money. It just works.”

Elle turned to see her baby girl in the arms of her sister. Camille seemed happier with Lucile than she did with her, and that made her 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 devilishly.

“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 your 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 awkward to be naked with you.”

“Oh, honey. I’m going to see you naked more times than your husband had 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.

Elle 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 big too, but it was mostly because of her milk. She was also tall but a bit chubbier than her sister. Thirty-two years old, which she didn’t look, but she also didn’t look twenty-two.

“Ready?” asked Lucile.

Elle nodded.

Her sister cleaned her carefully, paying extra attention to her buttcrack and labia. But it was not just the washing that caught Elle off-guard. Lucile also applied some sort of cream on her armpits, butt, and her most private parts. Once the cream was washed away, Elle saw her smooth skin lose every sign of body hair, including her pubes. She felt even more naked than before.

“Is this really necessary?”

Lucile just nodded.

After the shower, which lasted almost fifteen minutes, Lucile helped her older sister into the already-filled bath. She gave her a rubber toy, as if she was a little girl, and left her there for a while. After five minutes had passed, 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 she was now dry.

Lucile dried her with a towel and led her to the master room. 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, one as big as Elle herself.

Diapers weren’t the only thing in bed, though.

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

“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 year-and-a-half 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 did. Without hesitation and with an overpowering grip, she took Elle in front of a mirror and forced her to see her own reflection.

And that made Elle start to sob.

“It’s okay. Mommy’s here.”

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.

“Shall we start the weekend?” asked Lucile, grabbing her sister’s hand.

Elle nodded.

Part Two

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.

“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 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 gold 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.

Elle's tummy gave her a signal. One she knew too well. She had not made her morning's poop yet. And that could only mean more humiliation for the proud mother. And she began sweating cold, her tummy grumbling. It was a small, wet fart at first.

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 spreading 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 get Lucile to 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 now, 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. Wich, Elle thought, was true. Where else had they seen a woman her age wearing nothing but a diaper?

"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.

Camile nodded.

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

"Weally?"

"No! That's not true, my love. Your aunt it's 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 bes 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 needs to confront her sister and reclaim her motherhood and adulthood.

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

Lucile chuckled, "What are you doing?"

But Elle didn't answer; she rushed to get her daughter from her sister's arms. Lucile reacted immediately. She placed Camile gently on the floor, and with all her might, she forced Elle on her ass. The mother couldn't do much. Lucile was stronger and wasn't wearing a thick diaper, so she fell on her ass, feeling the mushy poop spreading even more around her crotch.

It was too much for Elle.

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.

"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.

Part Three

Elle cried her heart out, her thumb on her mouth, giving her little comfort.

"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 your 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 her as her mother 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 her. Every single time she did something wrong enough to earn a spank, her legs began shaking with that realization.

SMACK!

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

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.

SMACK! SMACK! SMACK!

"Pwease stopped!"

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 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 Camile.

"I think you're right."

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

More's to come!
