Chapter 2

Sarah’s Auntie, Helen, soothed her crying daughter and helped her out of her wet pull-up and into a fresh one. She was still furious at how cruel Sarah had been to Penny, but if all went according to plan then her three-year-old daughter was going to look positively mature compared to the little brat.

Helen was buzzing with anticipation. She couldn’t wait to go and see what Sarah looked like now. She knew how effective the hypnotist was – and this was exactly why she’d hired him. She’d been planning this with Sarah’s mother for quite some time. She’d given Sarah a final chance, just to be fair, but even she hadn’t expected the girl to be quite so rude. As far as Helen was concerned, her niece was getting exactly what she deserved.

As soon as Penny was in a dry pull-up, Helen took her by the hand and walked eagerly over to the back bedroom. There was a faint voice coming from within, followed by a high-pitched girlish giggle. Helen opened the door, and there she was... She smiled broadly sight of her bratty niece. The girl had been stripped of her crop top and jeans, and in their place was nothing but a glittering pair of fairy wings and a thick, white, disposable diaper bulging between her legs. Her bare breasts were out, and they wobbled on her chest as Sarah turned to face her with a dim, vacant grin on her face.

Helen couldn’t help but let out a cackle at the sight of her. “Hi sweetie!” she cooed tauntingly. “You’re looking very cute!”

“I’ve just finished telling little Sarah here all about how she loves being silly,” said the hypnotist. “Haven’t I, sweetie?” he asked the infantilized young woman standing next to him. “That nasty big girl is locked up inside your pretty little head. You’re just silly Sarah now, aren’t you?”

Sarah giggled again, nodding. “Siwwy Sawah,” she echoed.

“So she’s still conscious inside?” Helen asked the hypnotist while Sarah looked at them uncomprehendingly. Like Penny, who was still holding onto her mother’s hand, she looked as though she had no idea what the grown-ups were talking about.

“Oh yes,” said the hypnotist, smiling darkly. “The adult Sarah is still in there. She just can’t control her body at the moment.”

“Good,” said Helen in a satisfied tone. “I want it to be a punishment for her.” She looked into Sarah’s eyes. She wasn’t sure if it was just her imagination, but she thought she could see a hint of fury and horror behind them. She smirked. “Come on then, sweetie! Let’s get you and the birthday girl back to the party, shall we? We’ve got all sorts of fun things to do!” She turned to the hypnotist. “And nobody will see anything wrong with it?”

“Nothing at all,” he said. “I sorted that out when I did the mass session earlier. They’ll know she’s supposed to be a grown woman, but they’ll just accept in their heads that she’s nothing but an overgrown baby. They won’t think twice about her cute little boobies bouncing all over the place.”

“Mummyyy!” Penny whined. “Wanna go back to the party!”

“Okay, princess,” Helen crooned. “We’ll go back right now!”

Helen took Sarah by the hand and led the two girls back into the kitchen, with the hypnotist following behind, his eyes on Sarah’s padded bottom. To him, there was nothing better than taking pretty young women with attitudes and transforming them into overgrown toddlers…

Sarah was angry and terrified, but she had no way to show it. All she could do was rage and scream inside her head while her body smiled stupidly and toddled along beside her Auntie, her bulky nappy crinkling loudly with every unsteady step she took. What was going on?! Surely hypnosis wasn’t powerful enough to force her to act like a giant two-year-old?! They entered the kitchen, and immediately all the adults were swarming around them, cooing at her and Penny. She could see people chuckling at the sight of her bare tits, and some even reached out to tickle her tummy, making her giggle and squirm as if she was enjoying the attention.

“Time for some music!” her Auntie announced, and she started playing some embarrassingly babyish nursery rhymes on speaker. The brats were all dancing, and that’s when Sarah felt it, a sudden restlessness in her arms and legs. Without warning, her body broke into dance as well, and it wasn’t the kind of dancing she usually did at the club. There was nothing sexy or seductive about the way she was moving now. Sarah stomped her feet and waved her arms and shook her Pampered bottom to the silly baby music, giggling and squealing happily while all the adults watched and laughed. Even with her bare boobs out, the way they jiggled and bounced about on her chest just made her look ridiculous rather than sexy.

Inside her head, Sarah was seething. She’d never been more humiliated in her whole life! And then something even worse happened. Quite suddenly, she started wetting herself. There was no warning, no chance of holding it in. One moment she was prancing about in a dry diaper, and the next she was pissing. Her body didn’t seem to mind – she kept dancing and grinning like a moron, but internally she was cringing in shame as she flooded her nappy with wee-wee, and her baby-pants became droopier and droopier. Her warm pee sloshed about in her pants, and Sarah felt like she wanted to be sick. Other people had noticed her way her diaper was sagging, and the way it had become discoloured with her pee, and they pointed and chuckled openly. Her Auntie stepped forward and slipped her fingers down the front of her nappy without so much as a warning, but she only laughed once she’d felt the wetness there, and let Sarah go back to her absurd baby dancing.

The afternoon didn’t get any better. Sarah had to play pass the parcel and pin the tail on the donkey, all with a soaking wet diaper squishing horribly beneath her bottom. She’d promised herself she’d leave straight away if anyone asked her to go near a used nappy, but she’d never imagined she might have her own soggy diaper to deal with. She wanted to sink into the ground and disappear. She wanted to beat her Auntie and the hypnotist to a bloody pulp.

“Alright girls,” Sarah heard her Auntie say, once they’d finished yet another childish party game. “Who’s ready for cake?”

Sarah started jumping up and down in excitement just like the others, even as her stomach turned at the thought of the rich, calorie-heavy chocolate cake. They couldn’t do this to her! But there was nothing she could do but allow herself to be led over to the enormous chocolate cake. The other children (not the other children, she told herself firmly – she wasn’t a child) were all served their cake on cardboard plates first, leaving her bouncing on her feet, making her soaking wet nappy swing pendulously between her legs.

Grinning, her Auntie tied a pink bib around her neck and handed her a slice of cake. Sarah tried desperately to control her body, but she couldn’t stop herself reaching out and grabbing the piece of cake with her fingers and cramming it messily into her mouth. Soon there was chocolate all over her hands and face. She felt disgusting. She hated being messy!

Her Auntie smiled sadistically at her while she stuffed her face, and reached out to poke her in the tummy. “At this rate you might end up with a little bit of baby fat on your body!” she teased, her eyes glittering maliciously. “Wouldn’t that be adorable?” Sarah felt her stomach drop at the thought.

Once she was done, Helen cleaned her up – or at least, she cleaned up her hands. Although she wiped away some of the cake from around Sarah’s mouth, she made sure to leave her lips and chin smeared with chocolate.

At that moment, Sarah heard her tummy rumble.

Her Auntie tittered. “You can’t still be hungry!” she said. “Unless…” She smiled again, a dark and slightly eager smile. “Does little Sarah have to do a whoopsie?” she cooed delightedly.

Sarah just looked at her blankly, but she wasn’t sure she would have been able to speak even if she had been in control of her body. She felt frozen. No… Surely she didn’t mean...?

There was a cramping in her tummy, and Sarah clutched her belly. NO!

Helen leaned in close to Sarah’s face, grinning like a Cheshire cat. “Is the poopy express about to make a stop in your pants, Sarah?” she asked.

Shrieking inside her mind, Sarah bent her knees and stuck her diapered bottom out behind her. Then, with a loud grunt, the twenty-one-year-old started filling her nappy with a big, yucky mess. Her diaper bulged about behind her and sagged even more heavily between her legs, until it was halfway down to her knees. Her pretty face was screwed up with the effort of dirtying her pants. She knew she must look utterly absurd, a grown woman dressed in only fairy wings and a nappy, packing her Pampers like an oversized two-year-old.

She prayed desperately that this was all some sort of horrible nightmare, that she might wake up any second. But when she was done pooping her pants, she looked up into the smiling face of her Auntie and said, “Me made poo-poo!”

“You certainly did!” her Auntie laughed, taking her by the hand and leading niece through the crowd, into the living room. “Choo-choo!” she called happily. “Make way for the poopy express! Little stinker coming through!”

Sarah just stomped along happily, as if she didn’t care one bit that all these people were seeing were waddling along in a clearly loaded diaper. Everyone was laughing at her. Then she saw where her Auntie was taking her, and she felt as though a bucket of icy water had been dumped over her. There, in the middle of the living room floor, the hypnotist had just finished laying out a large, plastic changing mat.

Helen lowered her down onto it gently, and Sarah wrinkled her nose in revulsion as her bottom squished against the filthy mess in her pants. Then her Auntie leaned in close so nobody else could hear and said, “I hope you’re enjoying yourself, Sarah, because the hypnotist’s work isn’t just going to wear off. It has to be removed, otherwise you’ll just be stuck like this. And your mother and I have talked it over, and we think it would be best if you had a second try at babyhood. Maybe it will teach you to treat others with a little more concern. So get used to the feeling of a soggy, stinky nappy, Sarah. You’re not going back to normal for a very, very long time.”

Sarah’s lip trembled. It seemed that her hypnotised body had no intention of stopping her from crying.

“Oh Penny, princess!” Helen called, flashing a nasty look at Sarah before turning around. “Can you help me change your little cousin’s nappy? Just think of her as a great big dolly!”

Sarah saw Penny toddling over to her eagerly, ready to do what Sarah herself had been so disgusted by only a couple of hours earlier. As her legs were lifted into the air, and her Auntie got to work cleaning her up, Sarah thought about what her future would involve. She thought about all the messy mealtimes and baby dances and stinky diapers she would have to endure. Then she started wailing at the top of her lungs.
