Part of my (on-line) training as a submissive was forced chastity. I was ordered to buy my cb3000 and, after a few weeks of acclimatisation, was kept locked up for 13 weeks. The "head spaces" I went through...... from wanting to rip the damn thing off to wanting it never removed again........ totally enslaved me. These days, I don't have an Owner/Mistress & I greatly miss being locked up at "Her" order - but I am looking.........
To be in love again - and be denied all rights. Kept locked up, made to orally worship Her, forced to watch Her and Her lovers & orally clean them. Be unlocked & repeatedly teased to edge - and forced back into my cb unreleased. Be Her adoring slave and be controlled by Her, in every way.
I don't want riches or material things. Just to be at Her feet....

well I find your explanation very near to my own 'longest time' in chastity.If it is of any help,try to simply accept that you are in chastity and ,-as I did,-set your release hopes aside,even extending your time well past the return of your mother to her house.As I spent 2 months locked away,my madam has told me that the minimum will be 3 months without release next time,and I know I will prepare mentally for even longer,as I know this will help in the long haul to come.My madam is pleased with my attitude,and says she will ask me every week once my chastity period is up,'can you manage another week?'Of course,this is where it gets REALLY difficult,as the opportunity will be there for me to have the craved for relief,yet I will please madam no end by remaining voluntarily in my chastised state.And remember,there is no change in the regular oral duties I perform at her whim,so the temptation is SO overwhelming at times to ask for release...even as far as actually being unlocked,and,somehow after a half hour of being teased and stroked,sinking into submission again to her will,and asking to be put back into the cb3000 as I could manage a little longer....THAT is the attitude to take for you to achieve your long-term lockaway...the best of luck to you.
