It'll Be Funny - Part 1 (Patreon)

"Come on, Barbie, it'll be funny!" 

Barb rolled her eyes at her step-sister, tempted to point out they must have a very different definition of humor, if this is what the girl found amusing. She knew the girl was trying to get under her skin, though... That was the only reason she ever used Barb's full name, since she was well aware how much Barb hated it. "Why do you even have these?" she asked instead, poking at the padded garment, covered in cartoon characters.

"Umm, I babysit, duh," Cathy reminded her. "It should really be me going in for this job interview, not you."

"I'm not working in the daycare," Barb said, adding a silent, 'Thank God' to that. Kids were so annoying... She hated the idea of having to spend all her time around them, taking care of them. "It's the office. I probably won't ever even see them. They're hiring for that part, too, but I didn't apply for it."

"Whatever," Cathy shrugged. "You should still do it."

"Oh, come on!" Barb sighed. "Just drop it! I actually want to get this job, so I can move out of here... I don't have time for some stupid joke."

Cathy was the older of the two, but, since she was taking classes at the local community college, their parents weren't bothering her constantly to find a job. She didn't think they cared that much about her moving out - she was pretty sure they didn't really expect her to find work, and their eagerness was so they could use that as ammunition to make her go back to school with her step-sister - although, if she made enough money, she would certainly love to do that.

"Nobody would even know," Cathy promised, before switching to a more teasing tone. "As long as you didn't have an accident, and have to go ask for a change."

Barb fixed her with a withering glare. "You know that isn't going to happen," she said. "Especially since there's no way this thing will even fit me."

"Are you sure?" Cathy asked. That should have been a clue, a signal that Barb ought to back out now, rather than pushing her luck. As Cathy had pointed out, she was the babysitter... She was used to seeing them, putting them on kids. Barb knew next to nothing about them, other than what they were used for.

"Yes!" she exclaimed, not thinking of that in the moment. "Those are for babies, and I am definitely not a baby anymore."

"Okay," Cathy nodded. "Well, how about this? If it fits on you, you have to wear it."

"And if it doesn't?" Barb countered. It might be funny to make Cathy wear them instead, the next time she went babysitting, although if they didn't fit Barb, they probably weren't going to work on the other girl, either.

"It isn't going to, remember?" Cathy stuck her tongue out. "You're the one who's so sure about this... Don't you want to prove me wrong?"

"Fine," Barb rolled her eyes. "If it'll shut you up."

She reached down, picking the diaper up from where Cathy had tossed it onto her bed. Instantly, she was shocked at how big, and thick, it felt, compared to how it looked, especially once she began unfolding it. Maybe this had been a mistake, she thought, too late.

"Do you need some help?" Cathy asked. "I forgot, you don't babysit, do you? I bet you don't know how to put them on. Go on, take your pants off, big sis will take care of it."

"N-No, I don't..." Barb's mouth was dry, knowing she would have no chance of faking it if Cathy was assisting her.

"Oh, you do know how to put a diaper on? On yourself? That's strange..." Cathy teased.

"W-Well, no..." Barb had to admit, prompting Cathy to reach over and grab the diaper, then start unzipping Barb's jeans. In no time, Barb was standing there, stunned, a baby diaper wrapped around her hips. The sides were stretched a bit further than they were likely intended to be, but, in all honesty, not by much, definitely not enough for her to claim it didn't fit.

A sense of horror washed over her, realizing what this meant, what she'd agreed to, mind racing to come up with excuses to back out. "I-I don't think my clothes will fit over this right!" she finally spouted out desperately.

"Well, I doubt you're going to wear anything as tight as those jeans to your interview," Cathy responded calmly. "So just put those back on, and if they work, I'm sure whatever you do put on tomorrow will be perfectly fine."

As strange as the diaper felt between her legs, as much thicker as it was than her panties, Barb had no doubt her pants would fit, but it was her only chance to put a stop to this, so, as slowly as she could, she started sliding them up her legs, hoping Cathy would stop paying attention so she could pretend they were too tight, so she didn't have to wear a diaper to her job interview the next day...
