Incest is sometimes inevitable. I have few younger sisters and brothers but i have never done anything sexual with any of them. I had childish humping with one of my cousin when we were playing doctor, and it got more serious on/off relationship when we were teens.

Eventually when we reached adulthood it got even more serious and suddenly one day she came to tell me she is pregnant for my daughter. I was 25 years old young man then. Our relationship ended there.

Few years later, and I suddenly had a son with my friends ex-wife too.

Sounds bad already, but it is getting so much worse! I didn't cheat my friend with his ex-wife because she had already divorced him. We did cheated her new husband though, and he thinks my son is his.

My cousin also cheated her husband with me and her husband also seems to think my daughter is his.

Of course my friends ex and my cousin don't know about each other and both times their pregnancies quit our adventures and we haven't had sex since. I didn't knew anything of my daughters and sons lives and they do not know anything about me.

Fifteen years ago my children had met each other and were getting married before I even knew what was about to happen. I was in a shock after my cousin had invited me in to her daughters wedding and then in the wedding i realized she was going to marry my friends ex's son. But even then, what could i had do? I feel so low, but if I would had told them, not just their happiness but also their parents families would had been destroyed. They do not know im their father and i couldn't just tell them they can't have sex. As said, I didn't knew much about them, and still don't, other than that they have three kids today and as far as i know, they are okay.
