After I first showed my sister my penis I began to have more confidence to do it again.
After I showed my sister my penis and masturbated in front of her I began to relax more and couldn't wait to do it again. So, after school our parents weren't home from work until about six o'clock. When I got home on that first Monday after our first session I stripped and waited until she got back from her school. We both went to same sex schools. I heard the door open as she came in. Nervously I waited in my bedroom and called to her. I told her I was upstairs and ready to do it again if she wanted to see it. She said to wait a moment and that she was on the way.
As she came up the stairs I was so excited again I could hardly keep myself from coming, but I managed to hold back. She came through the door and when she saw me with my erect dick she gave me a big smile. She walked over to my bed, sitting down next to me and then reached across, holding it in her hand. Wow! I nearly fainted with the pleasure. She reminded me of how I said that it was hers to enjoy whenever she wanted, so I just laid back on the bed and let her feel me.
Pretty soon she began the up and down movement that would soon end in ecstasy. To have a girl hold it the way she did, was like no other feeling I had experienced before. My friends had done it to me, but this was something so special, no words could truly do justice to how I felt. She was only moving her hand slowly at first, so I urged her to go faster and to grip harder. As she was doing it I reached across and began to feel her breasts. They weren't too big at this time but they still felt good to me. They were after all the first breasts I had felt. She looked at me and smiled as I felt them.
With her hand moving up and down on my dick I soon felt that familiar build up of intense pleasure. It began to increase and I told her to watch out because it was about to come. She held on tight, moving her hand faster and then I came. My come spurted out and most of it landed on my stomach, with the last few spurts trickling out over her hand. She rubbed my stomach, spreading it all over and to my surprise and delight she began to inspect it on her fingers.
My little sister had begun to grow up very quickly indeed. I then asked her if she masturbated and she said that she did. I wanted to know if she would show me and she said to wait until she was ready. It was then that that I knew we would soon be having a mutual wanking session. I would just have to be patient and wait.
As we were talking my dick became flaccid and she watched it get smaller. It was getting near the time when our parents would be home, so to be on the safe side we separated and got ready for our evening meal. That night at the table we kept on giving each other little smiles.
This must have confused Mum and Dad because normally we were always having a go at each other and arguing. They both said how pleasant it was not to have us fight all the time and that they hoped it would last. How little they knew but yes, I hoped it would last too. No doubt I will post again sometime and tell you how it lasted and how she surprised me with her next request.
