I have worn a diaper at Chuck E Cheese before.
I believe I was around 8 years old and I was wearing a Pampers Diaper.
I was walking back to the table and my shorts fell down and my diaper was exposed.
A few kids laughed but it didn't bother me.
I decided to just take the shorts off and wear just the diaper, shirt and shoes the rest of the time I was there.
It felt so great.
A few years ago I was at Chuck E Cheese and I saw a kid of around 7 years old wearing a Pampers Cruisers diaper that was probably a size 7 diaper.
I could see the diaper sticking above his shorts waistband.
He didn't seem to care that it was showing.
