Author's Notes:

This one might have a few more elements from my "stretchy" wetting stories. But it's Pinkie. She can be as weird and stretchy as she wants.

Pinkie Pie woke up one morning in summer. She sat up, rubbed her eyes, and was about to go back under the covers to try to get back to sleep, when she suddenly remembered: Today she was going to an amusement park with her friends. She looked at the clock. They were going to be meeting there in half an hour.

She immediately changed out of her pajamas and into her white and pink T-shirt and a pair of jean shorts shorter and tighter than the ones she had worn to Camp Everfree, with white panties underneath. Then she went straight to the kitchen and made a big coffee to get her feeling more awake so she could enjoy more of the rides and attractions. She took a sip and recoiled, as the coffee was hot and hadn't cooled down yet.

She was thirsty, for it was a hot day and she had sweated a lot in her sleep last night. So she drank a dozen cans of soda, quenching her thirst as well as it being tasty. When she was done, she let out a loud belch, and giggled. Then she ate a few chocolate cupcakes for breakfast. By now her coffee had sufficiently cooled down and she guzzled it down like there was no tomorrow.

Pinkie then made her way to the amusement park, where she met with the other girls. They entered the amusement park, and they visited multiple attractions and went on several rides. After Pinkie rode a roller coaster with Fluttershy, who not only came out of it dry but loved it, she bought an extra large slushy, and drank it as she threw darts at balloons.

Then she went on the merry go round, riding a ponified version of herself, then through the House of Mirrors, and after a game of bumper cars, she drank an extra large lemonade.

Pinkie had just met up with the other girls at the food court for lunch when a sudden and intense urge to pee hit her from all she had drank. It then occurred to her that she had been so excited to go to the amusement park that she hadn't used the bathroom all day. "I gotta go, real bad!" she said, and she ran towards the bathroom. She felt waves of pee sloshing inside her as she ran.

She found herself at the end of the Bathroom Line. One of the Five Lines You Need To Stand In. When she had named it as such, Fleur hadn't made it, but Pinkie had been able to cheer her up. She held herself with both hands and pee danced. She was really having more fun pee dancing than worried that she might not make it.

Everyone in the bathroom seemed to take an hour, but they only took a minute, or a few. However, with each minute, Pinkie grew more desperate, and pee danced harder and more frantically.

"Can you hurry it up in there?" Pinkie asked a minute after the girl six spaces in front of her had entered the bathroom. "I really gotta go!"

Eventually the girl exited the bathroom, and it was Snips's turn to enter. Now there were four people in front of Pinkie, but she had to pee so badly she wasn't sure she was going to make it.

After Snips was done, a pink girl with blonde hair entered the bathroom. There were three more to go, no pun intended, but Pinkie was pee dancing faster than ever, about to burst. She couldn't say she was more desperate to pee than she had ever been in her life - this wasn't the first time, and she hadn't always made it.

Then, a loud fart could be heard from inside the bathroom. Pinkie tried her hardest not to laugh, but after a louder, wetter fart, followed by a splashing sound in the toilet, Pinkie couldn't hold back her laughter - or her pee. She immediately burst out laughing, in more than one sense of the word "burst", as only a second later she was wetting her shorts uncontrollably. She laughed for about ten seconds, soaking her shorts as torrents of pee flowed down her legs and drenched her socks and shoes.

When she stopped laughing, she looked down, seeing her shorts grow wetter by the second, feeling the warm wetness soaking her crotch and legs, hearing the pee sound, and smelling the pee smell. She blushed lightly, but sighed in immense relief, with an expression of absolute relaxation on her face, as she continued to wet herself.

The three people in front of Pinkie blushed and tried to look away from her, afraid that looking directly at her while she was peeing would make them lose it as well, though they didn't seem quite as desperate as she had been.

When Pinkie finished peeing, she said "Ah, that's better." She then giggled, finding it absolutely hilarious that she had peed herself, even though it hadn't been her intention to do so. She found all kinds of toilet humor to be funny, even if she was the object of it, though usually her only deliberate instances of it would be farting contests with Rainbow Dash, which Rainbow always won.

Sometimes, though not as often as Fluttershy wet herself, Pinkie would have too much to drink and not make it to the bathroom, or else laugh too hard at something with a full enough bladder that she'd have an accident in her dress, shorts, or whatever she was wearing at the time. And each and every time, she'd laugh it off, and encouraged her friends to do the same, especially Fluttershy, so she could feel better about her own wettings.

Pinkie rejoined the girls at their lunch table. "I didn't make it," she said cheerfully, and giggled. The other girls laughed as well. Pinkie had a delicious meal for lunch and then continued having fun in her wet shorts until they dried, not minding one bit.
