Chastity and orgasm denial discussion

Even though i am trying very hard to please my “Wife-Mistress-Keyholder-Goddess” & love of my life, i can still manage to screw up & disappoint her. Last week i had to go to a meeting at a building where they use a metal detector. There was a meeting there once before & i had switched from my stainless device back to my CB2000 with a numbered key tag. Well, i was allowed out of the metal one again for the meeting, but i was in a rush & didn’t adorn the plastic device that day. When i saw Mary for lunch she had asked me if i was locked, but i had to tell her no. i could tell by the look on her face that she was disappointed with my choice of not following instructions. She is taking a class & buried with studying, so she said i had to figure out how i was to be punished on my own. i have been paddled & flogged in the past for infractions, but she has no time for that with school right now. Being locked up is supposed to be something you dislike, so i need to find something that will teach me an important lesson so i do not repeat it. Now i didn’t pleasure myself while unlocked & had immediately relocked myself when i returned from work that day, so the punishment will be simply for being “unlocked without permission”. My wife doesn’t really have guidelines or a list of punishments, so i am asking other forum members for help by listing possible consequences for me. What do all of you think should happen for my display in being irresponsible by not locking up? i will show this post to my wife so she can choose the punishment later. If it helps, i already do many of the chores at home so adding to the chore list wouldn’t be punishment. i have not been allowed to have an orgasm since the end of May & do not have any regular schedule, Mary doesn’t like one & enjoys being random about it. It’s already been established that i am not getting one until she is done with school in July, so i must wait at least that long already. Any ideas are greatly appreciated, thank you. barbara
