I created my own diaper...I use a soft extra large bath towel. I fold it in half lengthwise, then I fold it in thirds lengthwise so the width of it is about four inches, then I fold it lengthwise so that there is either three or four thicknesses to the finished diaper.
I found the most wonderful and durable waterproof pants that are made very well. I order them from overseas and they only take about ten days to arrive. I can wash them daily and they will still last about six months. I think I only paid about $15 for three of them.
Anyway, I take the finished diaper, and I simply place in directly in front where they absorb the direct stream and I ensure that I have an extra large load to deliver and it makes the experience very hot and wet. It provides a very sensual experience, especially when the towel is completely saturated to the point that a puddle starts to form inside. If I am in a sitting position, the puddle will grow into a small lake.....super hot.....!
