I will try to drink at least a few bottles of water or a few glasses of water to get my bladder filled up to pee in the diaper.
Also I drink coffee in the morning and during the day as well while wearing a diaper and the coffee makes me need to pee within 20 minutes or so.
If I drink more coffee I can easily fill my diapers up quickly.
I really love a wet diaper and can't wait until my diaper gets wet.
The wetter the diaper the better.
I even like to sit on the toilet with a wet diaper that is full and then pee in the wet diaper again as it leaks into the toilet.
