I’ve done something wrong

i am very upset that i have displeased Master because i stupidly broke his rules about underwear. i wore some boxer shorts without his permission and i am extremely sorry.
i was asked at the last minute if i wanted to go to an event with some people from work. Because of the way the day would be organised i would need to change out of my work clothes and into something more casual at some point, as would some of the people i work with. i decided that i would probably need to wear some underwear.
As is normal, i filled in a form s-002 (request to wear underwear form) & emailed it to Master. Unfortunately i wasn’t able to give him the full 48 hours’ notice because of the last minute nature of the whole thing. i waited until 30 minutes before i was to leave, but still hadn’t had a response from Master, so i decided to wear some anyway and hope it would be OK. i immediately filled in the form C that i am required to when i need to confess to something i have done & emailed it off to Master. i went off to the event and had a good time.
On my return i discovered an email from Master saying that he was displeased with me and that if i didn’t hear from him in future i was to carry on as normal, not assume i can do what i want. i feel that i have let Master down badly and will do much better in the future.
Master has, rightly, decided that i should be punished with the cane. i am glad he has decided that as i did wrong and recognise that i need to be punished. He also said that i am only allowed to keep two pairs of underwear from now on; a jock strap with ‘197’ written on it and some rubber shorts. He sees these as most fitting for his slave. He made me piss on one of my jock straps and use it as a gag whilst i burned the rest of my under. i have amended the s-002 form to reflect my new underwear collection and will never wear any without permission again.
