How I learned about masturbation and then learned from my sister that girls could do it too!
When I was about 13, I had a friend named Randy that I rode with on the bus to school. One morning, while we were waiting for the bus, he told me that if you pull on your penis 35 times, something will happen. Well, I didn't believe him. Being curious though, I locked myself in the bathroom that evening and pulled on myself 35 times. I got erect, it felt nice, but nothing happened. The next day, I told Randy he was a liar...
Well, it didn't take too long after that to discover that 'something' did happen. Once I started to come, I wanted to do it all the time. Unfortunately, my folks weren't too forthcoming with information about sex, so I had to sort it all out on my own. Several trips to the public library (under the glare of the librarian) and I finally figured most of it out. Forty years ago, information wasn't readily available as it is today.
I readily shared my new found information with my brother and sister and of course they were fascinated as well. A couple of years later, I walked into the kitchen and found my sister suspended on the corner of the kitchen countertop by the crotch of her jeans. She blushed a bit and told me that it felt nice when she rubbed herself like that. Well, another revelation. Girls can do this too! I had no idea that girls could masturbate as well. (Back to the library to do some more reading!)
One day sometime later, my sister and I were home alone. We got on the subject of sex and I asked her how she masturbated. Years earlier I had let her watch me and I was very surprised when she said I could watch her now. I sat on the basement sofa and watched her take off her jeans and t-shirt. I hadn't really noticed that my sister had developed quite nicely! I watched her remove her bra then I watched as she slid off her panties, her red pubic hair her now in view.
My sister walked a few feet away and lay down on the carpeted floor. She was on her back, feet flat on the floor with her knees bent and spread wide open. I had a good view of her pussy. Some how, she sort of zoned out that I was there and I watched as she played with her breasts, rubbing them and pulling on her now very erect nipples. Then I watched her slide her hand down between her legs and she began to rub her clit and labia in little circles. This went on for a little while and then my sister stopped. I guess she didn't want to have an orgasm in front of me. That was ok, I had learned another lesson, never before having realized about the clitoris. Thank you sis!
Having been married now for many years, I have tried to interest my wife in masturbating with me but she insists she doesn't do it. (But she loves her hand held shower head!) I feel kind of cheated but every now and then I will think of my sister that day and I never fail to have a good orgasm of my own.
