Big Sister (Patreon)

You: Well isn't this my BIG sister! Do you need your diaper changed yet?

Sister: What are you looking at? Go away! Came to mock me, didn't you?
Oh look at that your big sister got what she deserved, didn't I? For making you wear little girl Pull-Ups when I was supposed to watch over you... Well guess what, it was totally worth it, to see you squirm in your training panties.

You: Oh yes, you had your fun... but those aren't training panties you're wearing, are they? Slightly bigger... perhaps, slightly more... babyish?

Sister: What, you think I care that I have to wear a diaper now? Pfft. This is by far the most lenient punishment mom and dad ever gave me. A diaper! I can still do whatever the hell I want, all I need to do is wear my diaper around the house. Easy. Plus I know they don't expect me to use it... they're not freaking psychos. They just want to teach me a lesson. So I hope you appreciate the view while you can. I definitely appreciated my view when you were walking around in your tiny pink Pull-Ups.

You: Riiiight. You may be changing your tune when you're parading around in your diaper at school tomorrow...

Sister: What do you mean, ''at school tomorrow''? They're not gonna make me wear this to school, they wouldn't dare! Certainly not with the uniform skirt they make us wear, mom always says mine's so short I might as well be flashing my.... panties. No.  If they want to make me wear a diaper, fine, but not at school, that wouldn't be fair, I didn't make you wear Pull-Ups to school! No, I'm telling you, I won't.

You: Oh, I think you will. You know very well what's gonna happen if you don't comply... It's gonna get worse for you. I heard mom talk to your teacher over the phone earlier. She's allowed to check if you're still wearing your diaper after class... And of course, if you need a change.

Sister: Eww, you wish! That's just disgusting. I'm not gonna... pee in it. I'm a big girl... unlike you. I don't have ''accidents'' in my sleep or... otherwise.

You: Oh sure, such a big girl, aren't you? A big girl wearing her big girl diaper. We'll see how big you are tomorrow.

Sister: No we won't... I mean... Yes we will!
