You are going to put on the thickest diaper possible (3 layers or such). Then, pour lemonade down the front and chocolate milk or something similar down the back (of the outermost diaper only, so that the diaper appears both wet and messy). Next up put on a pair of loose sweatpants or shorts and don't tie the waistband.
Take a pacifyer with you and drive your car out to a drive through restaurant. You will use your pacifyer as you order and pay for a large drink. You may not remove it except momentarily when needed to talk.
Now, drive to a drugstore or Wal-Mart. You do not need to continue using the pacifyer unless you feel very daring (alternatively, clip it into your shirt with a pacifyer tether). You will stand on the incontinence diaper aisle of the store for 5 minutes before leaving the store. If you need more diapers, buy them. This concludes your dare.
If at any time you feel an urge to wet or mess yourself, you must wet or mess immediately. Have fun
let me know if you succeed or fail. If you succeed, I will accept a similar dare, if you fail to attempt our complete it, you will receive a punishment.
