I know of a guy who used to pay school girls to thrash him with a wooden spoon in a local builders yard.
He was never into anything sexual with them.
One night we stopped and asked him about his latest exploits and unless I had heard the reply myself I would never have believed it.
Just before news at ten on itv.He would strip himself naked lie face down on the floor, then bang his toes of the ground until the pain was unbareable and his arse cheeks wobbled. BUT it had to be Trevor McDonald reading the news.
He then was then aback when we said we hadn't tried it we " didn't know what we were missing "
