When I was a kid, I used to masturbate while spying on my mother when she prepared for bed at night. I would slip into her bedroom while she was in the master bathroom and adjust the curtains in the bedroom ever so slightly so as to enable me to slip outside and window peep on her when she came out of the bathroom, naked. At a conservative calculation of approximately 250 times a year over a five year period, I estimate that I masturbated/ejaculated while spying on her over 1,200 times. That's probably a conservative estimate. The actual number of times is probably closer to 1,500. I only wish that technology had advanced at that time where I could have obtained a spy camera and recorded her. I would still be masturbating to those images today if I had them!
