Bratty Sub Made to Wet Herself

I have been misbehaving all day, thinking that you would just let it slide because it's my best friend's birthday. When we finally return home, you make me take off my clothes, leaving on just a red top and white shorts with red hearts. I am desperate to go to the bathroom but you order me to stay here. I grow more and more impatient, begging you to go to the bathroom but you refuse. Now I finally start to realise that you want me to wet myself, but I hold it in as long as I can until it is too much and I wet my cute shorts in front of you.
