Hang On For Dear Life/Wife

Two cowboys were sitting in a bar when one asked his friend if he had heard of the new sex position called 'rodeo'.

His friend said, "No what is it?"

"Well, you mount your wife from the back, reach around her and cup her breasts with both hands. Then you say, 'Boy these are almost as nice as your sister's'.

Now see if you can hang on for eight seconds."
