You challenged me to holding my pee all day at school, and I did it!! I was so excited to get home and make a video for you, showing you how good I was. In my video, I'm still wearing my school skirt, which I lift up for you to see my white panties. It feels so good to release my pee in them. It gets me so turned that I rub myself over the panties and ask you if I can cum for you... Can I? Please?
