Clothes switch

(In this I am making Allison 16 as she will have more freedom at that age and fits better with the story)

It was Sunday night and Allison and Jane were talking in there room while they were getting ready for bed, Jane was wearing her sleep diaper with a blue princess nightgown, Allison was wearing a pair of cotton panties with a plain pink cotton nightgown. The two were talking about the movie they watched that night called the parent trap about 2 siblings separated at birth that swap places to fool their parents into getting back together.

"I really liked that movie sis" - Jane
"I did as well, but it would never work in real life" - Allison
"What do you mean it would never work" - Jane
"I mean it isn't realistic, their parents would get suspicious if their child started acting different, and would piece it together that they swapped" - Allison
"I don't think they would, I actually think it would be pretty cool to be you though, less restrictions, the ability to wear what you want and not what your mother picked out, plus I would get to wear that cute school uniform of yours" - Jane
"Yeh but you would have to actually go to school wearing that uniform, and it isn't cute it is restricting and ugly" - Allison
"I wouldn't mind going to school if I got more freedom to do what I want to do, and I think the uniform is cute" - Jane
"You wouldn't like school if you went for a day, and that uniform is not what you expect, and if I was you I would get to stay home and play with toys, that is so much more fun than being forced to learn" - Allison
"Well how about we try it, I say we swap pyjamas right now and we will see if mum notices tomorrow when she wakes us up, if she doesn't I will go to school in your place and you can stay home" - Jane
"You know what I am gonna take you up on that offer, not because I think it will work but because if it does I wouldn't mind being you" - Allison
"Well "Jane", lets put on our own Pyjamas, I don't even know how I accidentally put on your nightgown" - Jane
"Ok big sis" - Allison

Allison and Jane quickly got up out of their beds and swapped sides, both stood at the bottom of each of their beds and started to strip. Allison slid down her panties and placed them in a pile with her nightgown, she then looked over and saw Jane place her diaper on top of her nightgown, "Hey I didn't agree to your diaper, I don't need them", Allison yelled. "Yes you do, mum put it on you "Jane" so she will be expecting you to be wearing it when she wakes you up", Jane replied. "I guess your right, but what about you wont you need it", }"I don't really have accidents anymore, I only really use them when I cant be bothered getting up from watching Tv or playing with my toys", Allison handed Jane her pile and took Janes pile in return, the two then proceeded to put on each others nightgowns, Allison was a little bit sceptical when putting it on as it was a little childish but then was happy as her mother refuses to buy her clothing like this anymore because she is apparently too old for them now, she looks over at Jane who is already wearing her cute pink nightgown and matching pink panties. Jane looked over at Allison once she was done and saw that she hadn't put on the diaper, "Do you need help with that or are you having second thoughts", "No I don't need help", Allison then slid the diaper up her legs and put it into place, she then let her nightgown drop over it however she noticed that it doesn't really cover it just like it didn't on Jane, this was quite embarrassing for her but thought that if everything goes to plan then nobody will think it is her and will just think it is normal for Jane to have a diaper or pullup showing.

Now that the two were dressed they turned of the light and both got into each others beds, Jane was excited to be Allison tomorrow, while Allison was nervous in case someone realised it was her in the morning and she would have to explain why she was dressed as Jane and wearing a diaper. The two both thought about their day as each other until they both managed to doze off.

What happens next?

Note, I tried something new with ways to make it easier to discover who is talking by using colours over the text that correlates to that person.
