Sis Gives a Loving Hand

I hadn't thought of my sister in a sexual way, aside from the usual growing-up curiosity and exploration, until eight months ago. She is two years younger than me and is single after a divorce 20+ years ago. Our Dad had triple bypass surgery eight months ago.(He's doing great now) She and dad live in Oregon and I live in Ohio, so I flew out and stayed for one and a half weeks during and after the surgery. I stayed with her (I'll call her'R')at her apartment. The day after the surgery R and I were talking and catching up on our lives. She asked how I was doing since my divorce two years ago. I told her I was doing OK except for being horny alot. We have always talked very honest and frankly with each other. She just seemed to let the comment pass. That night I pulled out the hide-a-bed and R went to her bedroom. It had been over a week since I had jerked-off so when I crawled into bed I had a raging hard-on. Since R had gone to bed I decided to take care of myself. I stripped naked and laid on top of the sheets. As I slowly stroked my hard cock I began to retreat into a sexual fantasy. As I became oblivious to my surroundings I didn't notice that R had come out to get a drink. I found out later that she had watched me masturbate for about 5 minutes before getting bold enough to approach me. The first that I knew she was there was when she sat on the bed next to me, put her hand on my dick and said,"Let me do that for you!" I was so shocked that I just stiffened and couldn't say a word. She pushed my hand away and picked up where I left off. I looked her straight in the eye as she continued to stroke my throbbing cock. She said,"I love you M, and I want to help you feel good. You deserve it." She guided my hand to her night gown. That was all the encouragement I needed. She must have had a plan in mind, for I discovered that she had no panties on and her pussy was very wet. When my fingers touched her clit she let out a moan and started stroking me faster. When I inserted two fingers in her it pushed me over the edge and I started to cum. She continued to stroke me as I shot four or five ropes of sperm on her hand and my stomach. She held onto my dick as she cleaned me up with some kleenex. When she was done she laid next to me with her head on my chest, softly touching and petting my penis. I was still petting her pussy as she talked. "I've thought about this since you divorced two years ago. I don't believe it is incest if there is no intercourse. I love you and really enjoyed watching you cum." As she talked, rubbed and pet my dick I started to get hard again. R said, "Good, I was hoping you would get hard again. I want to try something." With that she had me lay on my back as she straddled me. I was completely hard to the full seven inches by now. She slid forward until her pussy was right against the base of my cock. Then she leaned back with her hands on my thighs and started to slide the slit of her vagina up and down the underside of my dick. Up to where her clit hit the head and down the entire length to the base. This gave her full clitoral stimulation and me full contact without penetrating her vagina. The sensation was electric for both of us. She came first with a powerful orgasm that actually squirted her juices onto my balls. She could not contain her squeals of delight and ecstacy. This brought me to the top and I shot even more sticky, white cum than the first time straight in between us. She fell forward on top of me even before I finished squirting and kissed me hard. We laid like that for some 10 minutes before rolling on our sides and falling asleep in each others arms. This sort of sex-play continued for the next five days that I was there. Since then we have called each other and had phone-sex every two to three weeks. We are making plans to vacation together this summer. I'm getting hard just thinking about it.
