My sisters only wore dresses.
Our upbringing was very strict. The women only wore dresses, long dresses. As I got older I hit puberty and instantly was attracted to looking at my sisters since they were always around. I noticed how they developed breasts and tried to sneak peeks of them when they bent over.
I also noticed how when the wind blew hard or they walked fast the fabrics would stick and clearly show the form of there crotch and how they had a very nice hump. I would run and hide to masturbate to this.
At that age anything sets you off.
One day I was on the floor and my sister was sitting at the table doing home work, it was hot and she lifted her dress up to her knees showing her legs. Then she lifted one leg up placing the heel on the chair.
I caught a wonderful view of her undies and a clear outline of her muff as we call it.
Oh my I was in heaven I don't think she remembered that I was on the floor, or thought I could see her clear outline as her undies were very tight hugging those curves.
Then she started sort of rocking herself a little back and forth squishing her muff, man o man o man I could not contain my self and was laying on my raging boner.
This went on for a great while when I saw what looked like a wet spot in he crack that her lips formed, she carefully placed her hand down there and placed her hand moving the side up inside her underware when she felt the moisture she quickly got up and left.
When she lifted to the side, I got a quick view of her pubic hair and some of her private area, ooh
Oooo,oooo I tried so hard to save that image in my brain,
Every night and day I would jack off to those images.
Seeing her like that made me want more and now I always tried to find ways to sneak a peek.
I loved our old home with those key hole locks, the bath was upstairs and I of coarse like any boy dangerously would peek.
