I needed to pee and had just put on a adult diaper to relieve myself. I had started peeing when my dad walked in (no one knows about me pee fun), he didn't see anything as I quickly grabbed a blanket and held it in front of me (he thought I might of been changing clothes and said sorry) but he kept talking to me as I slowly filled my diaper all the way up. I really had to go, it felt so naughty to do.
