How about being forced to be a better dirty diaper boy using some simple discomfort to control you and keep your thoughts focused on
you using diapers = discomfort going away?
On say Friday night go poop - anyway you prefer, toilet, pants diaper, partner etc... instead of wiping you bum like a grown up you need to wipe your bum in such a way that you smear a thin layer of your filth inside of your bum cheeks, the bit of skin between your bum an balls and the inside of your leg (the groove the diaper sits in - up to just above your penis) then diaper up, you shouldn't be able to smell the poopy but the next day it should make you squirm in your diapers like a bitch from the itching/stinging, you are not allowed to itch/scratch or wipe your bum (you are allowed to sit and rub your diapered bum on a flat surface {like a chair} to allow some minor ineffective relive) you are NOT to be cleaned off for 36 hours (if you dirty up Friday night then Sunday morning is when your allowed to clean) if you need a diaper change then you are allowed to but wiping/clean up is not allowed just a straight forward diaper swap, if you poop your diaper then the changing procedure is to sit in it and mush it around for at least a half hour, masturbate until orgasm, then shamefully take your diaper off, your allowed 1 wipe with the diaper as it comes off - mostly to remove larger lumps of poop - but that is it you are then to put on another diaper {strait swap} but remember no lotion/powders etc.
On cleanup morning you need to cleanup really well, strong antibacterial soap and a good scrubbing cloth and a long warm soak is essential for removing the dirt and the smell from your skin.
You will now develop a bitch of a diaper rash that's going to constantly remind you for the next week of what a pathetic submissive diaper boy you are because I made you give yourself a rash!
For the next week creams/lotions are now allowed as a reward for good behaviour only - good behaviour is deemed as anything really dirty or anything that could lead to further diaper dependence, such as when your in big boy underware ensuring it always has a damp patch in the front, this can be done before or after urinating by squeezing out a little dribble directly into your pants, or any other kinky/dirty acts. just remember if the rash is hurting you it means you've not been a good enough boy to deserve cream, good boys wet and mess there pants, diapers, beds and anything they happen to be near when they can no longer hold it, sexual favours for others is also good behaviour aslong as you do'not orgasm for the next week, your reward for eating pussy or blowing a friend is the thought you've whored yourself out and knowing you get to put some diaper rash cream on.
Have fun! and remember the rash is there to constantly remind you and force you to be a good dirty boy.
