I love this site and I want to share my experiences with you.
Sorry for my english, is not my native language, I am from Spain
When this happened I was 16. I masturbated a lot, almost daily and sometimes twice a day. I was dating a boy since two months ago and he was always trying to put my hand on his erect penis when we were kissing, but I always rejected to do it because I've never seen or touched any penis before.
One day, coming home after college, I went to my brother's room, who was 14 then, opened the door without knocking and found him naked stroking his full erect penis. I stood with my open eyes staring at him who stopped what he was doing immediately, apologised and closed the door.
I don't know who was more ashamed; the fact is not one of us got out of our own bedroom until mom called us to dinner. No one made a comment that day or after, and we didn't look at each other that day.
At night, on my bed, I remembered what I had seen, a real big penis I thought, and I started to masturbate myself thinking about how nice it would be to watch this again and feel an erect penis with my own hands. I couldn't take the image of my brother stroking himself out off my head.
I could try it in a few days. My boyfriend was home alone for a few hours and invited me to his home to 'study'. We started kissing, he felt my breasts and as he used to, took my hand and put it on his crotch. But that time I didn't refuse, I unzipped his pants and looked for his penis with my fingers, he pulled down his pants and underwear and there it was, a fully erect penis for me. It seemed to be smaller than my brother's but it was nice.
I started to stroke him, but being inexperienced as I was, I caused him a little pain, because he told me to do it more gently. In a few minutes he advised me he was going to cum and then I felt his warm cum on my hand.
This was my first time, but I masturbated a lot since then, and he masturbated me too.
I'm happily married now and have a very active sexual life, but I keep masturbating myself alone, and we love mutual masturbation.
I'd love to tell of other experiences later.
