Making sure I’m plugged

Master is concerned that i am not wearing my butt plug at all times.
i am wearing it without fail, but i can understand that he needs to be certain that i am. So to make sure that I am, He has told me to try out the use of an anal lock. The idea is that the cock ring part will be placed on top of my ball weight so that I can’t remove it. I will then have no choice but to place the other end in my arse. We are going to be trialling it for a few days, so i will report back how i get on.
