My girlfriend told me about this site and I love to read the stories here.
I am 17 and I have a sister who is 18 and a brother who is 16. This is about my brother, but my sister and I have been masturbating together for about three years. We do it on the bed when nobody is home. We do it together and we watch each other. We look a lot alike so when we do it together I imagine I am looking at my own body as I watch my sister finger her pussy and rub her clit. Sometimes we each use things like cucumbers or carrots and we watch ourselves insert them. I wanted to give you a little background on my sister and me, but on to my brother.
My brother is a cute hunk of a guy. I know he masturbates and my sister and I tease him sometimes when he is in his room a long time with the door closed. One day about six months ago we were home alone together. I don't know where my sister was but I knew my parents wouldn't be home for hours. I had been masturbating with my sister but I had never done it with him. I was so curious about how big his cock was and how he did himself. I was so curious that I had decided to let him see me if he wanted to. Well, nobody was home so we were talking and I told him that if I asked him something would he promise to never tell my sister or my parents. He promised and so I took a deep breath and I told him I'd let him look at my pussy if I could watch him jack off.
He looked shocked at first but he said OK seconds later. He asked me where we should do it and I told him his room was fine. We went there and I unbuttoned my jeans and unzipped them and took them off. Next I took my T-Shirt off, then my bra, and finally I took my underpants off. I could see him looking at my body and it was exciting me. He finally started undressing and in no time he was standing in front of me naked.
Ummmm Yummmm. My brother's cock is big and thick and long and hard. If he wasn't my brother I'd let him stick his dick all the way inside me. He let me feel it and play with it. It felt so good and warm and hard. He wanted to see my pussy so I leaned back on the bed and let him look at my pussy and finger me really nicely. He was subconsciously jacking himself with one hand as he fingered me with the other. I told him I wanted to see him cum so I watched him jack his dick as I showed him how I rub my clit. He shot a big load of sticky white cum all over my stomach then he watched me rub myself into a giant cum.
That was the first time we ever did that. We have done it several times and he has kept our secret and not told anyone. I've been tempted to tell my sister to see if she would be interested in masturbating as a threesome, but I haven't done that. It's our secret.
