Soaked my denim jeans! Toilet-fantasy

One hot summer day I invited my friend over to help me film clips. She’s a bit of a bully but she’s really good at directing me on camera. We were about to film a ass worship clip in my super tight blue denim jeans , when I needed to go toilet. She was really annoyed and said she was going to make me hold it for along as I could to see how long I could last. How long do you think I can last?
