I once got caught in my sister's thong and skirt
Why were you wearing your sisters clothes?
I get sexual arousal from wearing women's clothes and imagining to be one.
While it was a little rude for you to go through your sisters things, it is very good that you owned up to your mistake. You should respect her and get your own clothing, you can wear what you want.
You are pretty understanding but I do feel naughty.
Clothing has no gender, if you want to be a man in a skirt you can, people just find it disturbing when you steal their things. It is really gross to share under ware with people.
