I use locking diaper covers, or a bondage belt with either shortalls or an extra layer being skorts with hidden pants, but those belt loops. My fantasy of not being able to when desiring to avoid pooping in the diaper or otherwise filling this diaper with waste to become unable to remove the locks even if I have the keys.

That is correct, I desire to be forced to leave this diaper in place with my diaper bondage fetish, especially if this leads to the diaper being filled with poop. My skorts with belt loops and hidden shorts are pink, but I want to know that I do not deserve to evade filling the diaper.

My fantasy I am trying to act out, is that I put the keys behind the bathroom door, and I enjoy the idea of being instructed to lock the keys away from myself, such as behind the bathroom door. This bondage gear is meant to enforce my use of these diapers, with my needing to not be able to ever until I release whatever bowel and bladder into the diaper, to be allowed to use the key or other release item.

I am roleplaying a rebellious big girl who believes she is too big for diapers. So I need to be reminded that not acting like I am ready for adulthood, means I need to be age-reversed. Any proclaiming I do not want to avoid using the toilet imposes the inability to use the toilet.

This "Littleforbig" line of diapers has this version called Potty Pants. I also have fantasized about being told that I will now use the diaper for its intended purpose because I deserve it. I am presently dressed like this with a bondage belt attaching the skorts and the short-alls, concealing the locking diaper cover from sight. Along with no beard or moustache allowed, because that is not a big-girl thing to have.

The more I desire to avoid soaking it with potentially overloading the diaper, the more difficult it will be to unlock the diaper bondage gear. With more potential diaper bondage-promoting materials arriving soon, to age reverses me to being a big girl, without yet being an adult. 

Also when a dominant is to correct me for misconduct, with the diaper that has diaper bondage attached. I want to know, I cannot operate the locks until the diaper is full. Since diapers are meant to be filled with both bladder and bowel contents. I deserve to develop a diaper rash from loaded diapers, then I can be treated for that diaper rash.

This will generate the locking diaper bedtime scene opportunity, with my loading bladder and bowel contents into the diaper, until it is either full or I need to go somewhere. Because I want to poop in the diaper, with needing to be able to operate the diaper bondage restraints are removed, until my bladder also empties. For the bladder and bowels must empty into the diaper. I am for fun, pretending to push my poop outward, with my poop control needing to during diaper bondage to be removed. 

Big girls do not yet have armpit area hair or maturity into pubic hair, so my adult hair even on the lip and beard will be taken away. And any avoiding of manifested prebiotics or other items are manifested that will promote bowel movement, will not be allowed. My fluid intake to soak my diaper will be unavoidable because staying hydrated is for my health. I so want to hear the phrase, "misbehaving girls need to learn their place!"
