Sibling Sex

When I still lived at home with my siblings, I fucked 3 of my 7 sisters, 2 were older than me and 1 was a year younger. I almost fucked a fourth sister but thank goodness I didn’t as she would have wanted more than sex. One time she told me she would marry me if not for her husband. Do I regret what I did? Yes. Do I feel bad about it? No, it was 40+ years ago and we were all kids trying to control our hormones and explore our sexuality. I’m glad none of them got pregnant.
