Mistress approved the punishment I suggested for myself in the end. I am to go without underwear for a whole week. This is my punishment for looking at her without her permission in the car on Friday. Going without underwear would not only be uncomfortable, it might also mean I might have an awkward buldge at the wrong time. It could be very embarrassing when I am in the presence of ladies, especially in the office. Mistress would also like me to get a remote controlled cock ring so that she can play with me even when I am not with her. I have seen a few being sold online. I just wonder if the ring makes a distinct noise when it vibrates. That would be quite embarrassing if it was to go off when I am in a meeting.
