Long Term Butt Plug Wear?

Hello Everyone!
This is my first post, so i hope it goes well. i'd like to take a moment to introduce myself. i am a slave to my long-time girlfriend and now-Domme, Mistress Melanie.
Anyway, my question is in regard to butt-plug training (or any other type of anal discipline for that matter). my Mistress has always felt that, in Her experience in the lifestyle, that anal training is virtually a necessity in slave training. (my Mistress was a 247 submissive for two years before transitioning into a dominant role and has had experience giving and receiving anal play)
Mistress Melanie has been training me to wear a butt plug for increasingly extended periods. This is where my concern comes in. Don't get me wrong, i love being plugged up; its so humbling and pleasurable at the same time. Currently, i sleep each night and often go to work plugged.
After a few weeks of the same routine, i got tired of being plugged. i decided to simply stop wearing my plug by removing it as soon as i was out of Mistress' presence. Well, Mistress caught me after a mere three days.
As a punishment for my direct act of disobedience, Mistress Melanie has established the following terms: i will be kept permanently plugged (That is, i will be plugged all the time aside from nature's calling), i will be allowed to take it out twice per day for quick breaks under Her supervision, assuming that my obedience levels are satisfactory; i will be allowed to wear my medium sized plugs, and last but not least; my butt plug will be locked securely in place with a harness from Lucy's Lair. (i do not know what it looks like, but it is pretreated leather with a cock ring and three padlock holders. Anyone know what i'm talking about?)
There is no point in trying to change my situation; Mistress Melanie has informed me that it will happen. If i was just a submissive and not a full-fledged slave, i would have a different future ahead of me. But i'm a slave, i don't really have the option of saying yes or no. When i was collared, i promised to submit unconditionally and wholeheartedly in my service. So, i'm not upset about this punishment, i'm just not looking forward to it. It is only a matter of days until the harness arrives which will then be promptly broken in.

.....So anyway, i apologize for rambling on and on and on, but i had some venting to do. i am ready to be a plugged up slave. In all honestly, it will probably be good for improving my service. i have often read about slaves who wear plugs all the time but i have not had the opportunity to personally communicate with one. My question: does anyone else, Domme or slavesub, have any experience with this type of play? Any slaves here undergo a period of service where you were plugged all the time? If so, are you still wearing your plug? Any Dommes done this with their subsslaves? I'm already guessing that 247 wear will greatly affect the sincerity of my devotion to Mistress in a positive manner. Anyone have any inputexperience to share about that?

Any and all responses are greatly appreciated. Thanks in advance!

i apologize to the rather long post. If you're still reading this... awesome!

Re. Long term butt plug wear

I think you've got a cheek coming on here and asking us what we think about it and asking for advice. Your mistress has decided that you should be pluggged all the time and that should be good enough for you. Your sole purpose in life is too do whatever she asks so I hope she notices this insolent behaviour and increases your punishment.
