In the woods, near my house...
I must have been very young, but I was allowed out in the woods with friends from the age of about 7 as they were very safe, I was very independent, and paedos didn't exist in those days.

One day, me, my brother and a friend of ours were in the woods, parking about as you do. We played on rope swings, kindly put there by bigger boys; we climbed trees (from which said friend had a shit - it landed with a satisfying 'plop' in the river beneath, and we called him a tramp for wiping his arse on leaves), and we went exploring through copses and thickets.

At one point, we came across a small clearing, and happened upon a wondrous sight. An older, ginger boy - probably about 14 or 15 - was sat on a bit of log, enthusiastically wanking his angry-looking cock for all he was worth.

Being young, we had fuck-all idea what he was doing - but it was clearly something very wrong indeed - and given the look on his face, pretty painful to boot. Concerned for his safety, we did he only thing we could - shouted 'ginger' at him and ran like fuck back the way we'd come, emerging breathless and laughing into the meadow a few moments later.

The boy never gave chase; I can only assume that he either ran off in the other direction, ashamed at being caught wanking by persons unknown, or that he completed the task with the dogged determination he'd shown.

I myself didn't take up my own masturbatory career until several years later, by which time such was my desire for self-abuse that it would have taken a lot more than a thin, reedy trio of voices shouting 'ginger' at me to put me off my stroke, so I can only assume the latter.
