A few months after the rather eventful sleepover in which Tommy did the impossible and out-held both her friends and six older girls, the three friends were planning for a visit from Pippi's cousin, Jenny Foxworth. She had been an honorary member of their club for a while, and they planned to use that as an excuse for a new challenge they had been developing since said sleepover. They were going to do a much more advanced holding contest, and claim that that would be her initiation.

One thing they had noticed was that the amount each girl had been able to hold was different, and that merely the length of a hold wasn't enough to determine bladder strength. So they decided it would be a contest on two fronts: they would measure both time and amount and use a point system to decide which girl was the overall winner. First of all, they would receive one point for every girl they outlasted, and when they were about to lose, they had to go in buckets, that would be measured at the end, and another point would be awarded for the volume.

And that was just the beginning of the rules! The girls had put so much work into planning, and had gotten everything together for their challenge. All that was left was to convince Jenny, but they were sure that it wouldn't take much to get her to agree to it, especially considering they were using it as her official initiation.

On the day that she arrived, the girls ushered her to their tree house almost immediately, barely giving her enough time to even put her bags down. They were too excited about their plans, though to everyone else it just looked like they were excited to see their friend after so long and eager to catch up.

When they were alone, Jenny immediately noticed the four buckets with a line drawn in front of them and said, "What's up with those?"

"Well, we decided that today would be a great day to make you an official member of the club," said Annika.

"And that's part of yer initiation!" continued Pippi.

"Pretty exciting, huh?" asked Tommy.

Jenny did not look convinced. "What exactly does my initiation have to do with a buncha buckets?"

"Well, see we were in this contest a few months back with my sister and her friends," started Pippi, before telling the whole story. When she got to the part about Tommy winning, the girl beamed and boasted, until Pippi interrupted her to finish. "So, anyway, we're gonna do something like that with you to initiate you!"

"That sounds ridiculous!" Jenny said, shaking her head. "There's no way I'm doing something like that."

"I can understand that," said Tommy. They had already planned for their response, and she went with what they had decided she would say. "I mean, with someone like me competing? I would be intimidated too, if I were you."

"I'm not intimidated!" said Jenny, just as they had predicted. She took no further goading and simply said, "What's the rules for this one? I'll pass this initiation with flying colors, just to shut her up!"

They explained to her the point system and the purpose of the buckets, as well as a rule that stated they could not go to the buckets until they had leaked. They could not pee in the buckets before they had begun to wet themselves, and therefore if any of them crossed the line, it would count as a forfeit. Besides that, they had to strip to their panties, have a round of drinks every fifteen minutes, and would do little mini-challenges to further test bladder endurance. If Jenny scored a three or higher, she would pass the initiation.

"First, we all go to the bathroom, so we start out on even footing," said Tommy.

"Yeah, about that..." Annika said nervously.

"What?"

"We kinda decided that since ya won the other contest, you shouldn't get one. It's more even that way."

"What?! That's so not fair!" she said, outraged.

Of course, Jenny, who wasn't even in on the planning for this event, knew exactly how to push back. "What? Miss Reigning Champion scared?"

"I am not scared! Fine, jeez, I won't go first."

~X~

After their bathroom breaks and their first round, the girls stripped to their panties and began doing dares, though at first, there wasn't much problem for any of them. It wasn't until about the fifth round that they started to feel the effects of their drinks, and though she wouldn't admit it, Tommy knew that she was feeling it a bit harder than the other girls.

"Alright, it's my turn to dare since I did it last time," Annika said, grinning. "And I dare Tommy!" The young girl tried not to grown as she was singled out. "I want you to do cartwheels!"

She smirked, playing it cool and saying, "That's all you've got for me? No problem!" But she secretly felt a bit nervous, knowing that this would be rather hard on her rapidly filling bladder. She got into position and began cartwheeling around the tree house, hissing a bit whenever she stumbled or fell, as this jostled her bladder almost enough to push her over the edge.

Her last fall caused her to leak just enough to leave a tiny spot on her orange panties, and she hoped that nobody noticed and counted her out straight away. Luckily, the kitchen timer they had snagged to tell them when to take drinks went off at that moment and the others were more distracted by getting that situation sorted out.

They passed around drinks, and she was relieved to notice that she was not the only one cringing as she downed it. Perhaps she would not lose as terribly as she thought she would today. At least, knowing that she hadn't emptied out beforehand like they had, she had a feeling that even if she lost control first, she would still probably do well in the volume portion of the contest.

After the drinks had been completed, they waited a few moments before it was time to begin the dares again. Tommy smirked and said, "Alright, it's my turn. Jenny, I dare you to do a handstand until the next round!"

"No sweat!" she replied, and got on the ground, pushing herself up in the air by her hands. However, her balance was off, and she quickly fell backwards. She tried to get back up, but fell again, feeling a small dribble escape. She got back up again and managed to maintain her hold for a while, but then fell, face down this time.

The sudden landing on her front placed a great deal of pressure on her bladder, and she sprung up, jamming her hands between her legs. The other girls giggled as they watched her squirm and struggle for control, bouncing at her knees. When she removed her hands, there was a small dark spot on her light brown panties.

"Yer gonna lose!" taunted Pippi.

"Not a chance," said Jenny, blushing at the teasing. The timer went off again at that moment and the girls all groaned a bit. None of them felt like their bladders could take any more, but with everyone still in the running, there was no way to tell what would happen next.
