Why i will be kept in chastity constantly

it's a long story, but i will make it brief.... basically, Mommy and i have been together on and off for 10yrs.. thru all that time, i have not always been faithful or attentive to Her and Her needs.. Through searching how i could possibly be changed to be faithful and attentive to what She wants.. She discovered chastity and it;s benefits to Her and us... hence why i am being kept caged by Her.. i think She wants to start out for short periods of time locked, but i am sure She will want me kept caged for extended periods of time.. we will see.
