I cannot believe that this happened to me. I have been going on this site for a long time and I thought, 'this stuff will never happen to me!' Boy was I wrong. This is what happened.
I had just walked in to my house two days ago and I saw my sister walk upstairs. She told me to come into her room with her. She said that she felt stressed and she wanted a massage. I said I would give her one. My sister is very pretty, she has a very nice big bottom, and lovely breasts.
So she lay down on the bed and told me to rub her back first. I started rubbing and as I got lower down her back I started to realise that she was not wearing any underwear, this was odd. I carried on massaging her and then all of a sudden I started to stare at her bottom, I almost had a full erection. I think my sister could feel it and said, 'You got a boner?' I didn't know what to say. I said yes and carried on. She told me to let it out, she told me to let my penis hang out of my pants. I couldn't believe it.
She said she wanted to see me masturbate over her body. By this time my erection was full and I could see her getting excited as well. I started jerking it while she was facing face down on the bed. It felt so good I couldn't believe it. She turned round and watched me while she just lay their watching me. She took off her top and told me to look at her breasts. I was ready to shoot my load. Just before I did she shouted, 'Wait!!' I said what happened, she moved right under me and told me to release it. I did what she said and she licked it all off her breasts. I still mess around with her a lot now.
I can't believe I just told everyone! Anyway, this is a memory I don't want to forget quickly!
