I was always horny as a teenage boy. Found a few porn magazines and watched a few late films on C4 in the UK. A friend of mine JC showed me the way to watch his sister undress and occasionally masturbate (I was 12 and she was 16) which was amazing to me at the time.

Unlike a lot of the 'stories' on here I was just a normal 12 year old starting puberty. Not a 9" long cock and up for anything with anyone. However I was horny and his (not that attractive) sister was so hot at the time.

The pair of us lads went to an average public mixed sex school. Neither of us were interesting to girls and we were a scruffy pair. However the school was very good with sport, in particular Netball. They had a few courts and aside from the school hours they had club/county games some evenings.

My school mate (JC) found a way onto the roof and we had a clear view of the showers and changing rooms. This was for girls/women from 12-40 and we would sit on the roof with ten smokes and watch them change.

There is not really a sex pay off but I loved being in school/streets/shops seeing girls and thinking 'I have seen you naked'

Awful invasion of privacy. But we spent hours every week on this. Hopefully none of the girls sussed it too...
