Oh Yes I have tickled my son so hard he wet his diaper.
He's tickled me so hard I wet my diaper as well.
I love having a tickle fight with my son and he loves it too.
I've always loved being tickled and I remember being tickled by my friend and he tickled me so hard when I was 8 and I peed my diaper and couldn't stop laughing.
I tickled him so hard that he peed his pants.
He should've had a diaper on as well.
