Phone Sex With Sister

I have always been turned on by incest. Oddly enough, I usually don't masturbate about members of my own family, but celebrities or other people I meet and fantasize about them being my sister or mother.

One day about 10 years ago, I was talking to my sister by phone, and she was complaining about her husband. My sister is three years older than I am and I have always thought that she was sexy. I listened for a while, and without really thinking about it, I told her that he should be happy to have an attractive wife like her. She seemed surprised, and then asked why I thought she was attractive. I now saw an opportunity. I said, 'don't take this wrong, but you have got huge tits'. She laughed and asked if I was a tit man. I said yes, and that I had been noticing her tits for quite a while.

At this point I started to get turned on and began jacking off. She asked if big tits were all she had going for her. My sister had been a prom queen in high school and was tall, blonde, busty. I told her that I thought everything about her was beautiful. I thought that I had been careful, but pretty soon, and out of the blue, she asked if I was jacking off. I hesitated and then told her that I was. It was silent for a few seconds until I asked if it bothered her. She said that it didn't.

I then decided that I would let go and make sure she knew how much I was enjoying it. I started talking dirty about how much I wished that she was there with me. Within seconds, I knew I was going to cum, so I told her so. She simply answered with, 'cool'. I immediately shot cum all over my chest. I have tried a few times to repeat the incident, but she isn't interested. I still masturbate to that beautiful experience many times since. I hope one day she lets me do it again.
