I've been turned on by allowing women to see me masturbate ever since I was about 15 and saw my older Sister's hairy pussy by accident one day. She asked me into her room to tell her if she looked nice in a certain pair of jeans. After I had commented, she changed back into the dress she had been wearing. As she pulled the tight jeans down, she pulled her knickers with them by accident and I saw my first pussy. She pulled them up - after letting me look for a second - and said 'That wasn't supposed to happen'
I kind of thought she had done it on purpose, or at least she was quite interested in my reaction. After that I used to spy on her through the bathroom keyhole when she had a bath or shower. Then one day I wondered what it would be like to be spied on by a woman myself.
I started to subtly let women who walked past the house see me naked for a second as if it was an accident, and as time went on I got more confident.
Finally when I had my own house and was about 23, I plucked up the courage to try to let my neighbour see me in my room wanking off. She was about 40 and lived across the street from me with her family.
I was home one day from work early and positioned myself so that she could see me from her small bedroom if she was there. They had a phone in there, so if she was upstairs and answered it, she would sit down and would be directly opposite me.
I sat on my bed naked for ages and finally it all happened perfectly. She picked up the phone and I was there slightly turned away from her so that she would not realise that I was secretly looking at her out of the corner of my eye. I was physically shaking with nervous excitement, but I stayed put. Finally she did a double take and had obviously spotted me. She moved so that she was just visible behind the window frame and she watched me as I slowly wanked myself off. I only lasted for a short time and had the most intense orgasm of my life. Afterwards she calmy put the phone down and walked out of the room.
After this, she seemed to be in that room a lot more than she had been, so I realised that she had not been offended and probably hoped to catch me again. I decided to let it happen more and more from then on, and she watched me cum lots of times.
When I saw her in the street she was always friendly and chatty, she never let on and of course as far as she was concerned I didn't know she was watching me, she thought it was her secret bit of fun.
I have other similar experiences, maybe I will put another one on soon.
Thanks for reading.
