Here is a dare:
Fill your diaper to the point it wont absorb anything anymore. Do this with whatever fluid you like. After this start filling up your ass with your enema kit. Take as much as you can handle and a bit more and put your diaper on. After that make yourself a bit slutty (short dress, a bit more make up then normal, you know the drill) and go shopping For an hour. As it is November more people will look at you when wearing a short dress, which makes this dare only better. When you shopping, you have two options:
1) fight the enema and hold it in, which will be very uncomfortable
2) let it go and humiliate yourself publicly. Your diaper will not absorb and i dont think i have to explain the rest.
Dont forget, when you 'choose' option two you still have to finish the hour of shopping and you might not smell very nice anymore
Have fun, and let me know how it went
