Chapter 4
Envy

“Dr Smith!” Jennie’s mother shouted furiously as she marched into the therapist’s empty waiting room, dragging her daughter along by the hand. It was after hours, and even the blonde bimbo secretary was gone from her place behind reception. “I know you’re here! Come out and explain yourself!”

Before she could reach the office door, Dr Smith had emerged, hands in his pockets, smiling politely. “Mrs Brown! And Jennie too. How nice to see you. What seems to be the matter?”

What seems to be the matter?!” Mrs Brown raged. “What do you mean what seems to be the matter? What the hell have you done to my daughter?!”

Dr Smith’s eyes drifted over Jennie, and the faintest smirk twitched at his lips. The outline of a thick adult nappy was visible through her tight jeans, and an inch or so of the plastic waistband was sticking out of the top, leaving no doubt about what the twenty-one-year-old woman was wearing. Her thumb was planted firmly in her mouth and she was sucking on it rhythmically, but when their eyes met, she yanked it out, her mouth wet with drool, and shouted, “You makin’ me act wike a dumb baby! I can’t stop… can’t stop copying my wittle sister! Whatever she does, I hafta act wike dat too!”

Dr Smith chuckled. “I was only helping you with your little problem, Jennie. I’m sure it was hard growing up as an only child all your life, only for your mother to suddenly have another baby. You were telling me how jealous you were of your baby sister and all the attention she was getting. Well, this seems like a perfect solution to me. If you act like her, you’re bound to get just as much attention, if not more!”

“You’re crazy!” Mrs Brown shouted. “Just fix it! Undo it now or I swear to God I will sue you until you’ve got nothing left!”

“Don’t worry, Mrs Brown,” said Dr Smith calmly. He walked over to them, taking his hands out his pockets as he went. “I think this should explain everything.” He held his phone up to her eyes, and at once Mrs Brown’s face went slack.

“There’s absolutely nothing wrong, you see. Jennie’s just being silly, as usual. You know how immature she is. She’s jealous of her baby sister, so she’s acting out for attention.”

“Mummy, stop!” Jennie cried, looking at her mother’s blank expression in panic. “Don’t wook, Mummy!”

“Hush Jennie,” said Dr Smith sternly, and Jennie’s mouth closed at once. “The grown-ups are trying to have a conversation. Go stand in the corner and poop your pants while I talk to your Mummy.”

A whine bubbled up in Jennie’s throat, but she couldn’t stop her body obeying. She fought to put her feet back under her control, but it was useless. She walked over to the corner, facing it like a naughty child. Then she bent her knees slightly and started grunting. She could still hear Dr Smith’s voice behind her.

“During our sessions, Jennie told me all about her plans to start acting like a toddler. She told me she was going to watch what her baby sister did and start copying those behaviours. So if her little sister sucked her thumb, she’d start sucking her thumb. If her little sister made a mess with her food, that’s what she’d be doing every meal as well. And if her little sister wasn’t potty trained, then she wouldn’t be using toilets either. I tried to tell her not to, but she was insistent.”

There was an especially loud grunt from the corner, and Jennie felt a yucky mess begin to fill the back of her nappy. “Nooo….” she whined softly. “Dat’s not twue…” Her face was bright red with shame, but there was nothing she could do to stop herself straining to make a dirty diaper. A strong rush of pee flooded her nappy as well, and it began to sag inside her jeans.

“Of course, it’s totally ridiculous for an adult woman to act this way,” Dr Smith continued. “But my advice is to give her exactly what she wants. If she’s going to act like a baby, then treat her like one. That ought to teach her a lesson.”

Jennie was still facing the corner, and her face was scrunched up with the effort of messing her nappy like an overgrown two-year-old, but she could just picture her mother nodding blankly along with Dr Smith’s words.

“If she wants to embarrass herself by acting like this, then you might as well make sure she goes all the way. Dress her up in onesies and tutus and pink, frilly bonnets – or just let her run around in nothing but her nappy. Feed her baby food and formula. Change her Pampers in the public park. Invite her friends to babysit. And of course, make sure she gets plenty of strict discipline. Maybe that will persuade her to start acting her age.”

Jennie finally finished pooping herself, and she whined again in disgust at the heavy, yucky load in the back of her pants, and in fear at Dr Smith’s words. She looked anxiously over her shoulder, and felt a horrible shiver run down her spine. The doctor was putting away his phone, and her mother was standing there looking perfectly satisfied.

“Thank you very much,” her mother said. “I’m so grateful to have your advice. I don’t know what I’d have done without you.”

“Not at all, Mrs Brown,” Dr Smith said graciously. “I know little girls can be a handful sometimes.”

“Oh they certainly can,” Jennie’s mother agreed, looking over at her panic-stricken daughter sternly. “Come along, Jennie. It’s time to go home. You can finish your corner time when we get back, after you’ve had a spanking.”

Jennie burst into tears. “Mummy, no!” she wailed. “This isn’t wight!”

But her mother strode over to her, grabbed her by the arm, and started dragging her out of the room. “It certainly isn’t! Twenty-one-year-olds shouldn’t need spankings and corner times. And they certainly shouldn’t need nappies.” Mrs Brown paused for a moment, then she reached down and quickly tugged Jennie’s jeans down her legs and over her feet, leaving her in nothing but a sagging diaper and her socks and shoes below the waist. “There. If you’re going to wear nappies like a baby, then everyone’s going to know it. Plus it will be easier for me to tell when you need changing.”

“Stob it, Mummy!” Jennie sobbed. “It’s Dr Smith! He hyp… hypno… he did something to you too!” She looked back at Dr Smith. There was a wide grin on his face, and his eyes were sparkling malevolently.

“Don’t be silly, Jennie,” said Mrs Brown impatiently, pulling her daughter over to the door and dumping her jeans in the bin beside it as she passed. “Dr Smith is a wonderful man who’s only trying to help us. You’re just a naughty girl who’s acting out for attention because you’re jealous of your baby sister. Now stop struggling, or you’ll be getting a spanking every night this week!”

“Waaaaaaaah!”
