Today my Mistress KH told me to wear my new pouch panties over my cage while going to the store for her. I usually wear sweat pants on weekends because they are loose around the crotch but are pretty tight around the butt. She knew my panty straps would show enough to make me nervous. Especially when I got to my car and looked back at her and saw the amused look on her face. I didn't notice any strange looks at the store but really have no idea if I was noticed which is scary and excited at the same time. We took a couple of pics before I left but she refused to let me see a pic from behind with my sweat pants on. She does't want me to know how much is showing because she wants me to do it again next weekend...
