Not So Grown Up

“I don’t need a babysitter!” Sandy pouted.
“Your parents obviously think you do, that’s why I’m here.” Natalie replied, hands on hips.
“No, I’m going out.” Sandy insisted. She had dressed up in a pair of tight velvety purple trousers, pink satin blouse, had piled her blonde hair on top of her head and put full make-up on. She tried to open the door, but Natalie stood in the way.
“Look, Sandy…”
“Sandra. I’m a grown-up now.”
“You’re 15…”
“I’m 16. Since last week!”
“And I’m 22, so I’m the grown-up here.” Natalie gently steered Sandy away from the door and into the lounge. She had to admit that Sandy had gone to an effort to look like an adult, but she had been hired to babysit her and didn’t want to lose her.
Natalie had wavy brunette hair, brown eyes, and was a curvy size 12. She was dressed in a blue t-shirt, and black trousers which would have been tight on a size 10. She entered the lounge behind Sandy and closed the door.
“How about watching some TV?”
“I don’t wanna!”
“Playing a game?”
“No!”
“You know what? You’re not a grown-up. You’re still acting like a child.”
“You’re a child!”
“What?”
“What?”
“Knock that off!”
“This is ridiculous. I can look after myself. In some countries I’d be married by now.”
“In some countries you’d be arrested for wearing pants that tight.”
“I want to go see my friends.”
“Well, tough. Let’s just watch some TV. How about some cartoons?”
“Funny. I’m going to find an 18 movie…”
“15 maximum.”
“We’ll see.”
Sandy looked around the lounge.
“Where’s the remote?”
“I don’t know, wherever you lost it.”
“Ugh. Fine, I’ll do it the hard way…”
She stomped across the room, still pouting, arms crossed over her chest. She reached the TV and bent down to switch it on.
RRRRRRIIIIPPPP!!!!
Sandy froze at the noise, and Natalie didn’t even try to hold in her laughter. Her tight trousers had split completely up the back seam.
“My trousers!” she gasped.
“Is that…” Natalie got a closer look at Sandy’s underwear, “Piglet?”
“Oh god.”
“So, you’re a very adult, very grown-up young woman, but you still have pink Piglet panties?”
“St… stop looking at me!”
Natalie smiled.
“You know what? You are going out tonight.”
“What?”
“Well, we can’t have you wearing torn clothes like that, we’re going to go and buy a needle and thread.”
“Wait a sec, let me get changed first…”
“Nah, it’ll only take a minute…”
Natalie grabbed Sandy’s hand and pulled her through the front door and into the semi-dark of the evening.

“This is so humiliating.”
It had only been half an hour while they walked around the shops in town that were still open, but Sandy had already run into a dozen people she knew from school, and every one of them had seen her underwear, mostly because Natalie would talk about it very loudly whenever she got close.
“You wanted to be out this evening, didn’t you?”
“Not like this! Look- the general store has thread, let’s just get it and go home.”
“Sure… we can do that.” Natalie was smiling again, and as they entered Sandy realised why- a big group of people from her class were hanging around, looking at DVDs and snacks.
“Actually, let’s not go in here…”
“Too late, we’re here. Now let’s get what we need.”
“No, really, I’m good. It’s actually quite a pleasant breeze. So let’s just go home…”
Sandy tried to leave, Natalie grabbed her wrist, for a moment Sandy’s blouse pulled taut over her breasts and then with a series of quick, small PINGs her buttons flew off in all directions.
“Eek!”
“Oh, what a cute push-up bra!” Natalie giggled. “Really draws the eye away from your puppy fat!”
“Oh, no!” Sandy tried in vain to cover her exposed front, while Natalie waved down a salesgirl who was standing right next to Sandy’s classmates.
“Excuse me, could you help? We’re looking for sewing supplies, as the little girl I’m looking after has had a few accidents with her clothes. She’s just trying to wear some things she doesn’t fit into yet.”
The classmates turned to look, and got an eyeful of Sandy, standing in the aisle in her ripped outfit, wishing the ground would swallow her.
“Certainly, ma’am, right here.” The salesgirl led Natalie to a rack at the end of the aisle, full of useful things including, on a low hook, a small sewing kit.
“Thanks. See, Sandy? We can get you all sewn up, and then you can change into something more suitable for your age.” Natalie bent to grab the sewing kit.
RRRRRIIIIPPPP!!!!
Sandy’s friends were drawn from the sight of her, to the sight of Natalie bursting out of her trousers. The rip tore much wider than Sandy’s had, so her underwear was fully visible, stretched over her plump buttocks.
“Oh… my… god!” Sandy began to smirk, “That’s Eeyore! You’re wearing Eeyore knickers!”
“I… I… Shut up!”
“The big, grown-up Natalie wears little girl panties!” Sandy crowed, “Looking a little old and faded, though. Wearing a bit thin?”
“Don’t tell anyone!”
“Oh, I won’t. For half your fee from tonight.”
“What?”
Suddenly, Natalie had her phone out and snapped a few good photos of Natalie’s backside. “And I’m going to stay out until just before my parents get home. Otherwise you’ll be all over Facebook by morning.”
“Fine. Just come home in time and don’t get me in trouble.”
Natalie grabbed a magazine, threw coins on the counter to pay for it, and ran off with it held over her backside. Sandy tied her blouse in a knot over her breasts, and walked with her friends over to a coffee shop.
“I love a happy ending.” She said, “No one gets to bully or embarrass someone else and get away with it.” She sat down in a deep chair.
RRRRIIIIPPPP!!!!
And shivered as the cold leather met her now-bare buttocks through the ripped seat of her underwear.
“Oh, knickers.”
