A story to learn the traffic signs

I was riding my bicycle when I saw a woman lying down. We fooled around until she was ready
First she opened one leg. Then the other. I put it in. She comple-
mented me on my size
and weight. After a lot of coming and going we tried different styles and speeds.
When I reached the point of no return she shouted, "STOP!" She said she wasn’t on the Pill. My excitement died.
Nine months later she phoned from the hospital I was a father. My world collapsed. I now walk.
