I think that when i first found out it was a nice feeling to touch myself in and around my pussy I was about 8 or 9, But I never managed to cum until I was 10. It was so good I could not believe it. And afterwards the usual guilt and would my mum or dad know. lol
Not quite the same thing, but when i was 17 i used to walk the dog along a path close to a clump of trees, not that thick but with the bushes quite invisible to others. The dog wondered in there so i followed only to find a dirty mens mag and a lot of used tissues by there. This really turned me on to think that some guy had his penis out there and looking at the photos. After looking around i dropped my jeans and panties, sat on a fallen tree and did the same looking at the mag. Always looking around sort of scared, i brought myself to a wonderfull climax which was very intense. A quick clean up and i was on my way again, everyone i passed i was sure knew what i had done, but that was just my guilt. susan
