Sister!

Don't go off and wear my underwear!

Underwear...? Oh? This is yours.

It was on purpose! The size doesn't fit you!!

The elastic will stretch out with you wearing it.

Oh...I'm sorry. As an apology, your sister will buy you some new underwear

I like some pink underwear!

Really!

Okay!

Fufufu...Alright then.

I'll dispose of these stretched out underwear.
