I woke up in a very wet diaper and I started to feel naughty knowing I needed a diaper change. I was going to put my cotton diaper on for the day, and those sometimes make me feel really horny. I changed out of my wet disposable and plastic pants and got my new diaper on and some fresh plastic panties. Pee-pee was already coming out right after I changed, and that got me going. I had to play with myself and go really hard, or I wouldn't be able to think of anything else all day.
