The Camping Trip - Part 4 (Patreon)

"Bunny, stop it!" Becky fumed. "I don't need these things! They aren't even mine!"

"Maybe they should be," Bunny giggled. "You're the one who wet herself last night, not me. "This is for the best."

"No, it isn't!" Becky rolled her eyes. "I-I don't ever do that... Not really... A-And I definitely don't during the day..."

But Bunny wouldn't let up. It was only fair, really, although that thought wasn't much of a comfort to Becky, while her little sister kept her real underwear held hostage, insisting Becky put one of her diapers on instead. All the times she'd teased Bunny for wearing diapers... Becky knew it was just a fluke, and she didn't need them herself, yet if their situations had been reversed - as they had been, many times - this was almost certainly what she'd have done. 

"Fine!" Becky hissed, snatching the diaper from Bunny's hand. "I'll wear the stupid thing, if it'll make you happy."

Bunny watched, grinning, as her big sister taped it on, then pulled a pair of shorts over it. "Do these cover them?" Becky asked, having a much harder time telling than she'd expected, staring down at herself.

"Sure!" Bunny chirped.

"Come on," Becky sighed. "Are you telling the truth?"

But Bunny didn't answer. Becky tugged at her shorts, starting to see now why, when they'd been younger and Bunny had worn diapers more often, the girl had so often left the house with them visible. Becky had warned her sometimes; others, she'd let it go, to teach her a lesson, sure that getting teased would help motivate the girl to stop having accidents. Of course, it wasn't a fair comparison to now... At least Bunny had a mirror she could have used, instead of relying solely on Becky. Becky only had her sister.

They had breakfast, which, to Bunny's credit, she did make on her own, something Becky hadn't been confident she was capable of. There wasn't much to do, since everything had already been chopped up and wrapped in foil, but the girl did get their fire going again to warm them up, whereas, the night before, Becky had handled that by herself.

"Okay," Becky said, once they'd finished. "Are you happy now? Can I take this off?"

"Nope," Bunny shook her head, not even taking a moment to think about it.

"We're supposed to go swimming today!" Becky whined, stomping her foot.

"And we will," Bunny promised. "N-Not that I have experience or anything, but my swimsuit would cover that diaper... Yours probably will, too, right? I know you like them skimpy... Surely it's big enough for that, though..."
