Little Sisters can be Such a Pain

by Cowkites

Elizabeth turned around, admiring the shape of her backside in the mirror. It was the weekend, and that meant shopping and fun with her friends at the mall. Being nineteen and beautiful meant that the mall was Elizabeth’s element, and she so enjoyed being in her element. The attention she garnered through men and boys alike hitting on her, the numbers handed to her, the fake numbers she wrote out; all of this stroked Elizabeth’s ego. She so looked forward to the weekend.

After adjusting her push up bra and the see through lace panties that so badly wanted to be revealed underneath her small skirt, Elizabeth sauntered downstairs, ready to grab the car keys from her mother and be on her way.

“I dunno mom...can’t you take me?”

Elizabeth’s younger sister, Kiara, sat at the kitchen counter; despite being thirteen, she had a habit of dressing younger. She wasn’t into fashion or appealing to boys as much as Elizabeth had always been. Kiara hadn’t matured as quickly as Elizabeth had and was content to keep her hair in pigtails and to wear the same cartoon-print shirts she had been for years. Just as their mother and many other adults had said time and again, Kiara was adorable; Elizabeth just couldn’t wrap her head around it.

“You know I have that skype call with my boss today; I have to be here. Besides, Kiki, I’m sure Elizabeth wouldn’t mind; she loves shopping!”

Elizabeth entered the kitchen just as her mother finished talking, curious as to what the two were going on about, “What? Little Kiki needs some more princess shirts?”

Kiara looked down at the book she had been reading, annoyed that her big sister always managed to say her nickname with such ridicule in her voice. Their mother just smiled and rolled her eyes, “No, Kiki’s starting to become a woman! She’s going to need her first real bra, and you’re going to help her.”

Elizabeth groaned aloud, her mother always found ways to ruin her weekend, “What? Mom, no. I’m not taking the little brat with me to the mall. Besides Mother Nature doesn’t give breasts to little girls still wearing cartoon panties; she can wait another year or two.” Elizabeth looked to Kiara, giving her the ‘you better agree’ look.

“Y-yeah mom, I’m fine. Really.” Slumping into her chair, Kiara buried her face in her book. She knew well not to get on Elizabeth’s bad side.

“Nonsense. I won’t hear anymore of it. Elizabeth if you want to go to the mall ever again, then you will help Kiki find a bra…” Looking at her watch, their mother sighed aloud, before looking back at her daughters, “...and to make sure you do as I say, I’ll be dropping you both off and picking you up.”

Kiara was thankful that their mother would be with her for a little while, but she knew that this would just annoy Elizabeth further. Elizabeth stomped her foot in annoyance, “But mom! I can drive us just fine; you need to stay here for your call.”

“I know when my call is young lady. Now both of you, car, let’s go!”

Kiara followed the fuming Elizabeth to the car, who did little more than angrily text on her phone as her heels clacked on the path from their front door. Sensing an opportunity to make the best of the situation, Kiara approached her mother and tugged on her blouse, “Hey, mom, since I’m becoming a woman and everything now...can I sit in the front seat?”

Her mother smiled warmly and tousled Kiara’s hair, “I promise to think about it, okay K--”

The sound of a car door slamming interrupted her mother and they both look over to see Elizabeth leaning over from the passenger side, “Maybe in a couple years. I can’t see how we’d fit Kiki’s carseat and diaper bag up here.”

Doing her best not to get upset, Kiara quietly moved to the rear driver’s side door and got inside.

Sighing aloud, their mother got in the driver’s seat and started the vehicle, “You know Elizabeth, you’re nineteen; you need to be setting an example, not acting like the younger, more immature one.” Elizabeth just ignored her and returned to her phone, ready to just get the whole outing over with.

As the car arrived at the mall, Elizabeth quickly hopped out, doing little more than waving a weak goodbye to their mother and quickly leaving Kiara behind as she was hugged and kissed goodbye.

“Come on, baby sis! I want to get shit over with...”

Kiara cringed at her older sister’s language and turned to see their mother’s car in the distance. She had to run to keep up, but doing so only worsened her feelings of immaturity. Elizabeth turned around in a huff, “Come on! I’m not going to hold your hand, let’s go! Do we need to buy you a stroller first? Jesus!”

Doing her best to ignore her big sister, Kiara entered the mall a safe distance behind Elizabeth who was too busy muttering to herself to notice Kiara’s distraught expression, “Can’t believe I have to waste my Saturday babysitting this brat. I wonder if there’s a daycare here I can just drop her off at.”

Kiara heard all of it, as Elizabeth fully intended, and despite seeing the storefront and knowing they could part ways after their task was complete, Kiara was growing more and more upset. At this point she would rather take the full blame of running off and ignoring their task than deal with Elizabeth anymore.

As they entered the store, Elizabeth’s phone began to rang; grabbing Kiara by the back of her shirt, Elizabeth stopped to answer.

“Hey! … Yeah, I’m there. … Sadly I’ve gotta help little Kiki buy a bra …”

Kiara squirmed in her sister’s grasp, but Elizabeth wasn’t letting go. Her big sister spoke loudly as she mocked Kiara to her friends, drawing attention from passersby. Feeling terribly self-conscious, Kiara sees a particularly cute boy staring at her and Elizabeth. Her eyes have begun to water as the older boy comes within a few feet of them.

“Yeah, right? … Couldn’t be further from needing a bra …”

The cute boy’s eyes still fixated upon them, Kiara watches in horror as Elizabeth pinches her chest and starts laughing, “Seriously … Flat as a fucking board … I told my mom she didn’t need it, but she wouldn’t listen … Yeah! Maybe I should show some initiative and buy my baby sis some diapers!”

Kiara opened her mouth in shock; the boy had heard, everyone around them had heard. She felt so incredibly humiliated. Bursting into tears, Kiara managed to free herself of her sister and run toward the nearest store; an older looking shop with a half-lit sign reading: Spells-R-Us.

“Oh my god nevermind. The big baby just started crying and ran off … hell yeah! Meet me here when you can! … A couple hours? That’s fine, I’ve got plenty of time …”

Kiara hadn’t paid any attention to where she had gone, only that it was away from her sister. Disregarding the shopkeep, she ran through a maze of dusty antiques before finding a quiet corner of the store. She sobbed into her hands as she sat behind a mannequin dressed in lingerie.

“Now, what’s a smart young woman like yourself crying about? Boyfriend troubles?”

Kiara looked up and saw the shopkeep through tear-filled eyes. He was an old, kindly looking man, a warm smile lighting up his face.

“I’m not a woman … I’m just a little kid… and that’s what little kids do, cry …”

Kiara spoke through sobs, though she grew less upset as the shopkeeper smiled at her, “Everyone cries Kiara; even your sister, Elizabeth. I wouldn’t be surprised if you saw her cry today.”

Kiara sniffled as she stared at the old man with wonder, “R-really? Wait...how do you know me and my sister’s names?”

The old man just smiled further as he offered Kiara a hand. Taking it gladly, she wiped her eyes as he led her to the store counter, “Just consider me observant … and one of the many things that I’ve noticed is that your sister has been treating you poorly; am I right?”

Kiara felt her tears welling up again, “Y-you heard her on the phone? She was that loud?”

Shushing her the old man held up a single finger and began to dig through an assortment of containers behind the counter, after a moment of silence, with Kiara being on the verge of sobbing again, he produced a diamond ring and laid it on the counter, “Your sister is a loudmouth, I’ll agree with you there; but do not take to heart what she says. By being upset you only make her feel as if she’s right about you. Instead, I suggest you take a look at this.” The old man slid the ring forward and watched as Kiara picked it up delicately.

“It’s a very pretty ring … but I don’t think I understand …”

Taking her right hand gently, the old man grabbed the ring from her and slid it on her ring finger. It was far too large for her, but Kiara watched in amazement as the ring slowly shrank to fit her finger as it slid in place, “The next time your sister treats you poorly, just imagine her getting a dose of her own medicine.”

Kiara stared in wonder, “What will happen?”

“You’ll see. I can assure you, though, that you won’t be running away from her crying anymore; that’s for sure!”

Kiara marveled at the ring on her finger as she held her hand up to the light. Realizing that she could never afford it, she sighed before bringing the ring down and attempting to pull it off her finger; only it wouldn’t budge.

“I’m sorry, but … I could never afford this. My mom only gave Elizabeth money for my bra … I don’t have any money.”

The man only smiled, however, as he crossed the counter and lightly pushed Kiara out the door, “Nonsense, consider it a gift; you’re a young woman now, you could use some pretty jewelry.”

Kiara grew excited as she heard him speak, practically bolting from the store with her new possession. She turned and waved, profusely thanking the old man before turning and skipping away, excited to find her sister and see what the old man had meant. Deciding that the ring represented her newfound womanhood, Kiara stopped her skipping and changed to a brisk walk; Elizabeth wouldn’t mock her anymore.

When Kiara returned to the store they were in earlier, Elizabeth was gone. Kiara quickly managed to locate her at a nearby fountain as she was talking on the phone and her voice traveled.

“... Oh god … hold on, I have to go … yeah looks like the brat decided she wanted to pretend to be a big girl again … I’ll see you in a bit …”

Standing up from her seat on a bench, Elizabeth grabbed Kiara by the arm and began to walk back toward the store, “I should’ve known your leaving was too good to be true. Come on, Kiki, let’s get this over with.”

Kiara allowed herself to be pulled along, no longer concerned about how others might see her or how Elizabeth treated her. The advice and instructions regarding her new possession was more than enough to keep her head clear. As they neared the bras, Elizabeth looked down at Kiara, a smirk on her face, “I wonder if we’ll find any that match lil’ Kiki’s cartoon kitty panties?” Kiara felt her face burn red in embarrassment as her older sister grabbed the back of her underwear and yanked upwards. Elizabeth held the waistband of Kiara’s underwear in place as she pretended to find a matching bra, “No, no … just not cute enough for my baby sis … no … not pink enough ...”

Kiara fumed as her thoughts turned to the ring on her finger and what might happen should she start letting her imagination run wild. To make matters worse, Kiara could see the boy Elizabeth had humiliated her in front of earlier approach. As Elizabeth caught sight of him, she sneered down at Kiara before tugging a little higher on her underwear.

He looked to be about fifteen; older and cute enough to fluster Kiara, younger and cute enough for Elizabeth to deign to speak to him.

“Excuse me, but uh-um I noticed you earlier and I just wanted to say that I think you’re -um- really pretty … would you maybe want to go out sometime?”

He looked away from Elizabeth’s gaze as he spoke, nervously straightening his shirt and fixing his hair. He didn’t even notice Kiara; his eyes were too busy trying not to linger on Elizabeth’s ample bosom for too long. Elizabeth looked as if she might laugh aloud; but more importantly, Kiara could see her smirk and the way her older sister looked out of the corner of her eye at her. Elizabeth was planning to humiliate her further. Kiara didn’t wait to see how she would do it.

Closing her eyes, Kiara began to imagine Elizabeth being in her position. She remembered all the times Elizabeth had been the mature one, and she had been called a kid; then she reversed them. With worry in her heart that nothing would happen, and her sister would just mock her and her immature notion of wishing, Kiara opened her eyes.

Elizabeth was still taller than her, she still stood in front of the cute boy, and he still stared at her; only now Elizabeth didn’t look so much like herself. Instead of the meticulous attention to fashion she normally exuded, Elizabeth looked as if she had been dressed by her mother. Her long brown hair had been pulled into pigtails and any makeup on her face had been completely removed. Elizabeth’s normally sensual wardrobe had been changed to one that could be better described as juvenile. Gone was her low cut top, short skirt, and heels; instead, she wore a pair of pink sneakers paired with short, pink frilled socks, a pair of pink shorts with flowers on the pockets, and a cartoon-print princess shirt with puffy cap-sleeves. To Kiara’s delight, Elizabeth no longer wore a bra, leaving little to the imagination as her large breasts pressed against the cheaply made cotton fabric. Even her underwear had been replaced with an adorable pair of bright pastel yellow panties decorated with cartoon kittens. Kiara was thrilled to see that it looked as if Elizabeth had become victim to the same wedgie she had given her.

Kiara now felt herself filled with confidence and maturity. Her clothing was smart and adult; gone were the bright colors and childish designs, they were replaced with fashionable and mature clothing consisting of a blouse, long-skirt, and heels. Part of Kiara wondered if her newfound maturity made her appreciate such clothing or if she had just always been too scared to try something new; either way she enjoyed the clear change in demeanor she and her sister had undergone. As she adjusted her clothing and admired Elizabeth’s purse that now hung on her shoulder, Kiara watched Elizabeth squirm and blush in front of the boy.

“Oh … oh my gosh … y-yeah, I-I could maybe go out for a date sometime …”

Elizabeth reached behind herself and began to absentmindedly pick the wedgie from her rear as she giggled nervously and played with her hair, “Um … so do you, like, want to see that new princess movie? My mom said it looked really cute.”

Kiara smiled to herself; seeing Elizabeth like this was simply too much fun, but it could be more fun. Grabbing Elizabeth by the hand, Kiara interjected herself between them, “I do so hate to interrupt you two, but we’re here to buy little Lizzy here her first training bra. We don’t have time for this.”

Elizabeth looked mortified, but did little to stop Kiara from dragging her away back toward the bras, “B-but Kiki! He really liked me I think … why did you have to embarrass meeee?” Kiara almost nearly laughed aloud at the sound of Elizabeth actually whining like a child. Even the way she said ‘Kiki’ sounded completely different; gone was the scorn of the usual obnoxious Elizabeth, having been replaced by the innocence of ‘Lizzy’. Kiara looked back to see her older sister’s reddened face and downcast eyes and was gladdened to see her usual attitude completely gone. Kiara doubted ‘Lizzy’ would even correct the name change.

Now it was Kiara’s turn to look through the bras as she dragged her embarrassed sister behind her. Pulling a couple cutesy bras from off the racks, she held them one by one next to Elizabeth’s waist as she pulled the waistband of her cotton panties upward and compared the designs.

“Kiki … come on … you’re embarrassing me! C-can’t we just go to the changing room already.”

Kiara needed only to glare in her older sister’s direction to cause Elizabeth to close her mouth and avert her gaze. After marching her around the store a bit longer, Kiara eventually led Elizabeth to the dressing room and pushed the bras into her hand, “Try them all on, and be quick about it.”

Left alone in the dressing room, Elizabeth looked down at the various bras in her hand; while she resented her sister for embarrassing her, she had to admit she liked how cute they were. Grabbing one she thought matched her underwear the most, Elizabeth took her shirt off and pulled the bra up onto her frame. Turning around in the mirror she stared at the connecting straps and their hooks and did her best to get her arms behind herself and finish putting the bra on. Her fingers fumbled with the hooks again and again. She could see herself growing frustrated from the corner of her eyes, and decided to try a different one as this one was clearly made incorrectly.

After several minutes of waiting, Kiara knocked impatiently on the door, “Lizzy! Are you playing around in there? Do I need to come in and help the little girl get dressed?” After a moment of silence, a weak whimpering reply came from behind the door, “I -um- think the bras are b-broken.”

Sighing aloud, Kiara quickly walked into the dressing room. Inside she found a red-eyed Elizabeth fumbling weakly with a bra in front of the mirror. The rest of the bras had been removed from their hangers and lay scattered around Elizabeth on the ground.

“Lizzy, arms at your side.”

Elizabeth listened without hesitation and stood still as Kiara reached around her. It was only after Kiara secured the bra with one hand that she realized that she had never done such a thing before; however, Elizabeth didn’t need to know that.

Turning around and looking in the mirror, Elizabeth was surprised to see that the bra fit her despite her breasts being so large; only, now that they were in the bra, it looked as if she had lost a cup-size or two.

“T-thanks Kiki.”

Kiara watched as her older sister shifted nervously in front of the mirror. Elizabeth was too busy working up the courage to ask for assistance with the other bras to notice the indecision on Kiara’s face and her obsessive rubbing of the ring on her finger.

After a moment’s hesitation, Kiara returned her sister’s normal mental capacity to her; having decided that Elizabeth with the mind of a thirteen-year-old simply wasn’t as fun as she thought it would be. Kiara watched as Elizabeth shook her head, her expression one of confusion.

“Wh-what just happened? Kik- Kiara?! The fuck did you just do to me, you little brat? Is that my purse?!”

Elizabeth shot forward and tried to grab the bag from Kiara who managed to quickly hold it behind her back. Her face red with anger, Elizabeth reached forward again; only this time, as Kiara moved to keep the purse away from her sister, Elizabeth reached for Kiara instead and grabbed her firmly.

Kiara squirmed in her grasp but she couldn’t escape the strength that came with their age gap. Elizabeth grabbed her around the waist and yanked her over to a chair in the corner of the dressing room. Grabbing Kiara’s skirt, Elizabeth looked down at her younger sister with glee, “I don’t know how you did it, you little runt, but you’re gonna pay! First thing’s first; a spanking! Fitting for my baby sister.”

Kiara’s eyes widened as she was being pushed into her sister’s lap; thinking of the ring and what the old man had said to her, Kiara began to retreat into her mind once more. In a matter of moments, Kiara felt Elizabeth’s grip weaken and the sound of a weak and scared voice crack next to her, “I-I’m sorry Kiki! I-I didn’t mean to do that! I promise!”

Elizabeth shook in fear as Kiara pulled herself up from her lap. Despite being the older sister, it now appeared to Elizabeth that she barely came up to Kiara’s chest. She suddenly felt a great fear of making Kiara upset and shook helplessly in the chair as she continued to apologize.

Kiara had in fact only changed Elizabeth’s perception of her, but given her reaction, that was more than enough. Grabbing Elizabeth by the wrist she pulled her out of the chair and then took the seat for herself. In a swift and easy motion, Kiara pulls Elizabeth across her lap and yanks down her shorts.

“N-no! Kiki please I’m sorry! I’ll be good!”

Kiara couldn’t believe that just moments ago, she would have been the one in this position; and knowing her sister that would not have been the end to her embarrassment. Kiara hadn’t been spanked like a child in years; she couldn’t imagine a more humiliating way for her day to be ruined. Kiara was glad to show Elizabeth how it felt to be the smaller sister.

Laughing to herself, Kiara grabbed the waistband to Elizabeth’s cotton kitty-cat panties and yanked them down to her knees. Elizabeth had begun to kick her legs and flail her arms at this point, something Kiara easily put a stop to. Elizabeth gasped as her sister overpowered her with ease and grabbed both her wrists behind her back. Helpless and humiliated, Elizabeth began to cry as the first of her spankings stung her rear end.

“I’m sorry! I’ll be a good girl Kiki! Pleeeeeeaseee!”

Kiara continued to swat Elizabeth’s reddening backside as her older sister whimpered and squirmed. She couldn’t believe that she finally got to give Elizabeth the punishment she so well deserved.

“I’ll do whatever y-you want! Puh-please -I… no … nooooooo!”

Elizabeth gasped loudly before sobbing full-force and going limp in Kiara’s lap. She blubbered softly as Kiara continued to spank her a few more times, before finally noticing what Elizabeth had done. Elizabeth, Kiara’s older sister and tormentor had begun to wet herself. Beginning to wail now, Elizabeth does her best to hold back her utter humiliation, but Kiara’s teasing and the continued spanking prevents her from doing so.

“Oh my god! I can’t believe mom thinks such a little baby like you could be ready for a bra. You’re not even ready for big girl panties! Are you?”

Elizabeth looked up at Kiara, her lower lip quivering. Kiara just smirked and spanked her again, “Are you?”

“No…”

Elizabeth was a mess by the time Kiara finally let her stand back up. She had ended up urinating on not only herself, but her panties, her shorts, Kiara’s skirt, and the floor of the changing room itself. Completely humiliated, she remains docile as Kiara forces to look at herself in front of the room mirror as she pulls her wet underwear and shorts back up.

“I really shouldn’t be surprised that little Lizzy ended up crying and wetting during her spanking; that sounds just like you doesn’t it?”

Not giving Elizabeth time to answer, Kiara grabs her by the wrist and leads her out of the changing room and back onto the store floor.

“Kiki! P-people can see me; where are we going?” Elizabeth did her best to tug her shirt down over her embarrassment, but the accident if far too apparent to everyone as Elizabeth is marched to the store counter. She looks about in panic as people point and watch her; her eyes grow wet and her lips begin to quiver as they pass a mother and child that looked to be about five.

“Mommy, that girl needs diapers! I don’t need diapers anymore but she does!”

“That’s right sweetie; some girls like her take longer to learn how to use the potty like a big girl.”

Mortified, Elizabeth was in tears by the time Kiara had reached the counter and was talking to the cashier. She looked to be about sixteen, but to Elizabeth she felt incredibly older and bigger than her. It didn’t make any sense to her, but her mind was too mixed up to make sense of it.

“Excuse me? My little sister Lizzy had an accident in the dressing room; where could I find some clean clothes for her?”

Elizabeth felt a surge of annoyance pass through her as Kiara referred to her as the little sister. She didn’t care how big or grown-up everyone else seemed; she knew she wasn’t some little baby girl. She’d show Kiara!

“Aww no need for the grumpy face, cutie! It’s okay you haven’t gotten the potty down yet. Plenty of little girls still need a little protection and help from their big sister or mommy!”

The cashier leaned over and lightly pat Elizabeth’s head, completely disarming her and causing her to question just how old she was. Why would a sixteen-year-old treat a nineteen-year-old like that? Looking down at her soaked pink shorts and princess shirt, she began to wonder if she really was even thirteen. After all, she was dressed like a little girl and she wet herself. Maybe that’s why the cashier seemed like such a grown-up, because she really was just a big baby.

“You can find some clothes for little Lizzy over in the children’s section. Plenty of cute stuff a little princess like her will love…” then, under her breath, “...and the baby section is next to it. You should be able to find something that’ll suit her...needs.”

“Thanks, Lizzy really can be such a handful sometimes.”

The cashier waves goodbye to Elizabeth and mouths ‘bye-bye Lizzy’ causing further doubt in Elizabeth’s mind regarding her own age. She stumbles behind Kiara as she is led back through the center of the store and toward the kids’ section.

As the two sisters walk through the aisles of colorful clothing, Elizabeth’s mind wanders from the bright mascots to the children walking with their parents all around her. As Kiara looks through the racks, her hand slips from Elizabeth’s and from the corner of her eyes she sees her older sister begin to absentmindedly suck her thumb.

Elizabeth marvels at how all the kids around her seem so much bigger than her; so much more grown up. Having forgotten her previous accident, Elizabeth removes her hand from the bottom of her shirt and runs her fingers over the clothing before her. She takes no notice to the several children pointing out the urine stains on her clothing to their parents or the drool collecting on her chin.

Before long, Kiara reappears next to Elizabeth, lightly grabs her free hand, and leads her confused out of the kids section and back toward the dressing rooms. As they grow near, Elizabeth notices that the previous dressing room they had been in now had janitorial staff inside and a wet floor sign visible from behind the curtain.

“I am so tired of moms bringing their precious little angels in here to try on underwear when they’re not even potty trained yet! I’m so tired of little brats pissing themselves and wailing all over the store!”

Kiara smirked as they passed by; she could tell by Elizabeth’s reddened face that she had heard as well. She wondered how her obnoxious older sister would take being called a ‘little brat’ for once.

Elizabeth was far more distraught than she let on; only her confusion hid just how upset she was. Looking down at her still soaked clothing, she began to wonder if she really was just some little brat incapable of being potty-trained. Was she really nineteen? Even thirteen? She felt like a four-year-old and, with her all pink attire and pigtails, she certainly looked like one. Kiara stood only to Elizabeth’s chest, but the way she held herself made Elizabeth feel like the little sister. That was when Elizabeth noticed what Kiara had grabbed for her change of clothing:

Underneath her other arm, Kiara held a box of shoes that was covered in nursery rhyme characters wearing different pairs of shoes, text on the box boasted that the shoes lit up with pink lights and squeaked with each step, so that you knew where your ‘little one’ was at all times; on top was a folded pink sundress and a pair of frilly white socks with pink trim; Elizabeth’s eyes widened in terror when she noticed Kiara’s last item: cartoon-princess decorated packaging for extra-large, ultra-absorbent pullups.

Kiara was going to dress Elizabeth like a toddler, and a young one at that. There was no way the stuff would fit, but Elizabeth was too frightened to try it. She tried to shake herself of Kiara’s grasp but only received a glare and a warning from her sister. Finally managing to free her thumb, Elizabeth mustered up the last of her maturity; intent on not becoming what Kiara kept making her think she was.

“I don’t know what you did to me Kiki … b-but I won’t stand for it! I’m not a baby! I don’t wear pullups and I definitely don’t need my little sister leading me by the h-...!”

Elizabeth flinched as Kiara dropped her hand and set the clothes on a nearby shelf. Without saying a word, Kiara grabbed Elizabeth by the arm and bent her at the waist. No amount of struggling could free her; Elizabeth’s damp shorts and panties were pulled to her ankles in the middle of the store and she was spanked three painful times on the rear. She held back her desire to cry, even as she saw customers and staff beginning to turn and stare at the display.

“S-stop! I-I’m the big si-sistew! Not a baby!”

Another painful barrage of spankings and Elizabeth was practically on her knees crying in front of Kiara. The pale skin of her butt has reddened on the right cheek where Kiara had handily punished her

“I-I’m sowwy...puh-pwease don’t make me wear pullups…”

Elizabeth doesn’t even notice her speech regressing as she begins to beg and plead with her sister to end her humiliation. Thrilled to see her sister in a much more fitting position, Kiara relents but only to let Elizabeth stand and pull her underwear up; her shorts still around her ankles, Elizabeth is dragged off whimpering as her sister grabs the pullups and returns to the baby section.

Raising her voice so that nearby parents and their children can hear, Kiara scolds her sister, “Lizzy, the way you’re acting, you can forget pullups; you want to wet yourself and cry like a baby, then we’ll dress you like one.” Elizabeth opens her mouth in shock as Kiara pulls a large pack of diapers off the shelf and begins to drag her away; only this time they head to the women’s restroom instead of the dressing room. Elizabeth tries to think of a way out, but her head soon becomes muddled with thoughts of making the situation worse. She couldn’t imagine being spanked in public again; there was no telling how much Kiara could end up humiliating her. Sucking on her thumb for comfort, Elizabeth toddles behind Kiara and hopes beyond hope that this is all just a dream.

Once inside, Kiara makes quick work of stripping the confused looking Elizabeth nude. Elizabeth breathes a sigh of relief as she watches Kiara pull down the changing table and set the clothing and diapers down; none of what Kiara has picked out is big enough for Elizabeth. She hopes that Kiara will give up this foolishness once she sees just how ill-fitting they are.

“Alright Lizzy, up-see-daisy!”

Elizabeth cries out in a mixture of shock and delight as Kiara grabs her about the waist and easily lifts her into the air before setting her upon the changing table. The once seemingly small table supports Elizabeth’s weight easily, and, from Elizabeth’s perspective, is more than large enough for her. She watches in anxious anticipation as Kiara pulls a large strap across her stomach to keep her from falling off and then sets a familiar looking bag on the corner of the table. Elizabeth feels as if she should recognize it; perhaps it’s her mother’s purse?

Once Kiara reveals the powder and wipes inside, Elizabeth finds herself giggling around her thumb at her own stupidity; of course, it’s her diaper bag. As the cool feeling of powder and baby wipes on her crotch sends tingles down her spine, Elizabeth begins to wonder why she thought anything odd at all today. She was just a big baby wasn’t she? And Kiara may have a bit of a stern side to her; but she was a good big sister.

Kiara could see Elizabeth becoming lost in her thoughts as she slid a thick, pink diaper under her butt. She could tell that Elizabeth was enjoying herself in the moment, and while she wanted nothing more than to humiliate and punish her older sister for her cruel ways; seeing her completely docile and quiet for once was almost as good.

Taping the diaper shut, Kiara admired her handy-work. Elizabeth still sucked on her thumb as she squeezed her legs together, causing the diaper to crinkle. The infantile Elizabeth marveled at the thickness of her new underwear; she couldn’t even touch her knees together anymore.

“Oh my! What an absolutely precious baby! Yes you are! Are you being good for your big sister, hmm?”

Kiara was too focused on the task at hand to notice that a woman had entered the bathroom. She looked to be around their mom’s age and, judging by her reaction to Elizabeth, she must be a mother herself.

“What’s the little darling’s name?”

Elizabeth’s face was a mixture of anger and confusion; Kiara wondered if she should step in, but as the woman continued to fawn and tickle her sister she decided to simply go along, “Her name is Lizzy. Isn’t she the cutest little princess?”

From the changing table, Kiara and the strange woman felt like giants to Elizabeth. She could feel conflicting emotions rise as she felt an odd feeling of embarrassment from the situation. Elizabeth began to question her age once more, slowly beginning to remember the events from earlier in the day. Her anger maturing and becoming a fraction of what it once was, Elizabeth opened her mouth to right the situation but found her words caught in her throat.

“Ba ba ba goo daaaa…”

Did she just baby talk? The two giants next to her seemed to think so. Was she sucking on a pacifier, was that why she couldn’t talk? When did that happen? Did Kia- Kiki, do that? It was getting harder to think as she ran her tongue over the nipple in her mouth. Nothing felt certain anymore.

“Has she said her first word yet?”

Maybe she really was a baby. Wasn’t this what happened to babies? Having your diapers changed in the bathroom and parents gushing over how cute you are.

“Not yet! She’s such a cute little goober, I don’t know if she ever will!”

Freeing Elizabeth from the strap and setting her down on unsure legs, Kiara got to work dressing her sister; first came the dress, far too childish to be confused for anything other than a baby’s dress and far too short to cover the thick diaper around Elizabeth’s waist; then the frilled socks; and finally, as Elizabeth clutched the stranger’s dress for support, Kiara slipped and velcroed the light-up sneakers to her sister’s feet.

Elizabeth tugs on the clothing excitedly as the grown-ups talk, surprised and thankful that such cute clothing fit her. Her hand wanders to her crotch and she squeezes the thick padding gently, giggling as it crinkles in her grasp. For a moment, the once mature and aggressive Elizabeth’s eyes have glazed over; the only sounds she makes are the soft suckling of her pacifier and the light crinkling of her diaper as she scratches her rear. Kiara is more than pleased to see her sister’s complete loss of outward maturity and attractiveness.

Now who’s the big baby, hmmm Lizzy?

“You’ll have to let me babysit her sometime; she is such a treasure!”

“I’ll be sure to tell mom; Lizzy really can be a handful, so be pre- oh, hold on!”

The sound of a familiar ringing draws Elizabeth back into the adult world. Kiara is holding her hand as she talks on Elizabeth’s cell phone; only, it’s not Elizabeth’s. Elizabeth is too young for a cell phone; isn’t she?

“Speaking of … looks like mom is here; me and little Lizzy should be going. Isn’t that right baby girl? Does the princess wanna see Mommy? Go home and take a nap?”

Kiara and the woman laugh and, despite her initial excitement to see her mommy, Elizabeth can’t help but feel annoyed. Deciding it was probably just the mention of a the nap, Elizabeth just nodded before waving goodbye to the nice lady.

It was only until they were outside the mall that Elizabeth began to realize something was off. It was her shoes. They seemed a little humiliating, even for a baby; didn’t they? And didn’t those people in the distance … didn’t they look familiar?

Kiara saw them as well. Elizabeth’s old highschool friends. She looked to Elizabeth and could see the growing puzzlement on her face. They were only a few yards from the car; once they were home, Kiara could put the finishing touches on Elizabeth’s new life.

“Hi girls! Lizzy, were you a good girl for your big sister today? Did you behave yourself?”

Elizabeth began to express her anger even before she was fully aware of its full presence, “I’M NOT A LITTLE GIRL! SHE IS! SHE’S THE BIG POOPYHEAD BRAT! I-I WEAR BIG GIRL PANTIES AND I DON’T NEED TO BEHAVE MYSELF TO ANYONE!”

Kiara grinned ear from ear as she watched her mother’s expression turn to one of anger and exhaustion; furthermore, having predicted Elizabeth’s actions, she turned to see just what she had hoped: Elizabeth’s friends approaching.

“Elizabeth?! Oh my god guys, it IS her.”

“Whoa! Is this the new outfit you were talking about buying? It uh … definitely suits you.”

Elizabeth could do little more than stare stupefied as her mother grabbed her by the wrist and yanked her diaper down around her ankles, “N-no mommy, no! My friends are hereeeeeeeeeeeee! D-Don’t! Guys it’s not what it looks like!”

Things couldn’t be explained, however, as magic was dictating almost everything around her. Seeing a far more fun opportunity than making everyone see her sister as a baby, Kiara decided to make only their mother see her as such.

“She’s wearing an actual diaper! Like, do you see how big it is? She must actually use it like a baby.”

To make matters worse for ‘poor’ Elizabeth, her mother had begun to spank her with little to no regard for her daughter’s utter humiliation, “Mommy puh-pleassssssse!”

“I heard she was weird in bed. Bet she likes to call guys ‘Daddy’!”

Then Elizabeth looked as if she saw a ghost and her lip quivered fully before she burst into tears. Kiara knew the expression: Lizzy had an accident.

“Oh my god … this is … this is … TOO GOOD! Josh are you getting this on film?”

Kiara reached in the diaper bag and handed her mother the changing supplies as Elizabeth’s ‘friends’ gathered around. Her mother seemed not to notice their behavior and instead just seemed relieved that the fight had left her daughter’s limbs.

“You all seem like very nice boys and girls; would any of you be willing to babysit little Lizzy here when me and Kiara are away?”

Little Lizzy whimpered behind her hands as her delicate and red rear was powdered and as her friends turned tormentors began to clamor to offer up availability to babysit her. Once back in a fresh diaper, Lizzy sniffled and hid behind her mommy as the mean older kids left.

“Bye baby! See you soon!”

“See you this weekend princess!”

Utterly defeated, Lizzy took her older sister Kiara’s hand and allowed herself to be led around to the passenger side. She resigned herself to the back seat and sighed internally as the car door opened to reveal a large pink babyseat sized to fit her. She did not fight as Kiara strapped her in, tickled her, and baby talked down to her; she was too tired to fight.

Maybe I do need a nap…

As she stared past the back seats, Lizzy felt her eyes begin to droop. No amount of effort on her part could get the straps holding her in place to make sense to her, nor could they force her eyes to stay open. Part of her knew that when she next woke she would be in a crib; another part of her told her not to worry. It wasn’t long before she began to snore peacefully in the backseat, to the delight of Kiara and her mother both.
