Full Warnings: non-consensual drugging, shaming, and graphic physical abuse, possible rape
John secretly slips something in Sherlock's tea that makes him need to pee, then sets him up to piss himself. Then John shames Sherlock about the 'accident', and punishes him for making a mess. Sherlock in no way enjoys the humiliation or the punishment (which is excessively painful). It's up to you whether any part of the punishment is sexual in nature or if it includes rape.
Bonus: John continues to drug Sherlock. After a few weeks of this and increasingly painful punishments (including being beaten directly on his cock), and then even more punishments when John catches Sherlock 'messing with his health' by avoiding liquids, John pretends to get tired of the messes and makes Sherlock wear a massively thick nappy, and when his pants don't fit over it he gives him a super short skirt instead that does little to hide what he's wearing. John only changes it once a day, no matter how often Sherlock fills it. The punishments for not making it to an actual toilet continue.
Bonus 2: Include the Yard. After all, surely Sherlock's 'accidents' don't only happen at home? And What about Mrs. Hudson? How does she feel about all these new messes?
Bonus 3: Mycroft sees what's going on. Instead of putting a stop to it he puts up more cameras to enjoy his brother's humiliation and pain.
