Like most members of this forum, I seldom mess my diaper due to the inconvenience of the immediate and thorough cleanup required after. However, nothing quite makes me feel like a little boy in need of diapers like making a big mess in my diaper every now and then. My fantasy is to drop a load in my diaper that is so huge it stretches the diaper tight as it bulges in the rear, squishing everywhere, and then makes the diaper positively sag from the sheer weight of it when I'm finally done.
Does anyone have any ideas of how I can make this happen in a way that is safe and feels authentic?
