This is my experience about how i saw my mom naked for the first time and then masturbated. The first time i remember seeing my mother partialy naked was when i was 7 y.o. She would come from work and go to her bedroom to change. I entered the bedroom with her and played around and she didn't mind that i was there and would undress normally. I was pretending not to be watching but would stare at her all the time when she wasn't looking at me. I remember clear as day, she took off her pants and her blouse. She was standing in her bra and white cotton pantys and a black pantyhose over the pantys. Then she took off her bra and put on a shirt and shorts. But those 10 seconds of seeing her topless and just wearing pantys and pantyhose most probably had the biggest impact on my whole sexual life. Back then she was still in her late twenties (about 28-29) and looked gorgeous. What a beautiful breasts she had, quite big they were and small brown nipples! And her long legs in that pantyhose(at least they looked long to me as i was only 7)!
Later, when i was 10 i started to masturbate, and at age of 13 i started to watch porn movies and getting my first ejaculations. At age of 14 i got tired of movies and magazines so i wanted to see a real naked woman. One summer night it was jast mom and me at home. Mom went to take a shower. I got an idea to go and watch her through the keyhole that we had on our bathroom door. As i approached my eye to the key hole i almost got a heart attack of what i saw! There, 2 meters away from me was my own mother, completely naked. I got an instant 100% erection. She was standing in the tub soaping herself. She was now in her late thirties, got a little fat all over but nothing too much. It just gave her more sexy curves. Her tits were little saggy, belly rounder and also were her thighs. She was soaping her self with water from the shower running down her body.
But i saw a new thing on her body, which i have never seen before. It was her vagina! It was very hairy and thick bush, big and wide triangle of black and curly pubic hairs! That was the most beautiful thing i ever seen. Although i have seen many naked women on TV and magazines, but none of them had a bush that was big and hairy like my mom's. I fell in love with it. Since then i have a strong sexual desire for women with unshaven pussies. I didn't took me long to cum as i watched my mom's massive bush.
I'm 21 one now, and my mom is in her early 40's and i still use to peek at her every once in a while. Those are the best orgasms i ever have.
