The first step was to go to the local hardware store. and buy a plank. I wanted a paddle that wouldn’t cause a girl any harm, but that can bring her to tears and a bright red ass with one stroke.
So I bought a length of wood about two centimetres (2/3 of an inch) thick, and 12 cm (5 inches) wide.
From that you can make a paddle that a submissive woman will look at wide-eyed, and start to imagine how she’ll feel when it lands.
