Haha!!! YES!! I did that with my ex sometimes! I loved it and so did she. A few time I would say….
"Come here little one, and stand still for Daddy." Then I would put my cock down the back of her diaper and pee down the back of it soaking the front. I believe I also did it in the front once too.
THIS. Is so hot. I’ve only seen one picture of this but I think it would be incredibly sexy to do.
