I am looking for a story that i read on this site but can't find anymore
It was about this guy that had an accident (might have been a car crash) and lost the ability to go pee. The doctor has a device for this with 2 butons, one that activates the bladder and makes him pee and the other makes his anus relax and makes him poop.
His wife gets her hands on a copy of this remote and diapering ensues.
The story became a bit more sexual towards the end.
