Enjoying It ... Finally.

When I was fourteen and my sister was fifteen, just as what our mom saw as being a precaution, she put my sister on the pill. Well, the two of started having sex. It was easy, fun and convenient and without all of the hassles of involving anyone else. When Mom discovered she about hit the roof, although she realized that there was really no way to keep us from doing that, so she just cautioned us about not letting anyone find out.
So the whole time that we were growing up my sister and I had had sex regularly and we both loved it. Then she went off to college and then I did and we pretty much went our separate ways and we were both married. Then four years ago my sister divorced and two years after that I divorced. So my sister and started spending more time together and we quickly found ourselves having sex again and it was wonderful. No, we are not madly in love, but we are loving towards one another and we get along great and are well suited to each other.
So my sister and I moved in together. We told mom and while she was not all together approving of this arrangement, she saw that we were perfectly happy and actually having a good relationship and has accepted it.
And no, for anyone who might be wondering, my sister and I are not planning on having and kids together. I think that we left it a bit late for that anyway. And so far as morality, we are not hurting anyone, we are not planning on having any children together, we do not carry guns, we do not do ilegal substances, we are only having a relationship which we both find satisfying and for the first time for either of us that is quite pleasing.
And as a note to mom, we have never let anyone find out. Everyone just sees as this really well suited couple.
