When I was 12 and my sister was 11 we started having sex. It was a rough time at home, our mother had died and we sort of turned to each other for comfort. Soon though, we were doing it just because of how fun it was. We kept at pretty steady until I turned 15. After that we had a few more sesssions but were done before I graduated.

we've never really talked about it since, and both moved on with our lives. First college, then work saw us on oppiste sides of the country. We've stayed in touch, but seldom see each other. I'm 37 now.

Our Grandmother passed away this past summer and between the funeral and taking care of the estate and property we've been in the same place more than we have in years. At the funeral I found myself looking at her and thinking of her in a sexual way again. She's still in great shape and the boob job she got about 6 years ago really makes her look hot. Still I didn't do or say anything.

Last weekend we were back for the closing on the sale of Grandma's house. We had both arrived at the property early, intending to look things over one last time. Her husband and kids were still at a hotel and my wife hadn't flown out for this.

We were upstairs when I noticed her crying. I gave her hug to comfort her and we both just stood there in each other's arms for several minutes. Then she just blurted out "I want you."

We were kissing and pulling each other's clothes off before I knew it. she pulled me to the floor and I was shoving my cock into her wet pussy. We went at it like we were possessed. Her nails tore into my back, and I was nibbling at her breasts. Didn't take either of us long to climax and shoot off inside her.

We lay there panting for a while, then started at it again. I was pretty proud to rise to the occasion so quickly, but I was feeling just like we were teenagers again. This time we took it slow and really enjoyed it.

When we finished we both hrridly got dressed. Her husband and the realator pulled in just as we both finished making ourselves presentable. No one seemed to suspect a thing.

We snuck off togeather every chance we got for the rest of the weekend. Being sad about selling the house gave us a perfect excuse to "comfort one another" or "catch up on things" Her husband was oblivious to what we were really doing.

Her oldest daughter did come close to catching us. (She's 14). Everyone was down at the hotel pool and my sister and I snuck up to her room for a quick blow job. I'd just cum in her mouth when I heard the sound of the keycard reader. I hopped into the bathroom, while my sister hurridly did up her blouse and licked her lips clean. Her daughter came in and asked for some money to get a soda.

When the weekend ended we promised each other not pass up any chances to have sex. We both agreed it never felt as good as when we are doing it. She's planning on coming down to visit for thanksgiving.

One thing has started to worry me. We were bareback every time and I came inside her most of those. I didn't ask her about birth control, we were just both too horny. Well I guess we'll see what happens.
