Please help! I'm looking for an incest story.

[Phillip1999Rus]

So, I'll write what I remember.
1. The world has likely survived the apocalypse, DNA testing is available (death penalty for detecting an incestuous child, should a test be carried out), but the lands are under the control of a baron/count.
2. Women are genetically altered. They experience an annual period when they experience an extremely strong desire to copulate. The live birth rate is low, and most are stillborn.
3. The father is dead, and a mother and son live together and have a dog(The mother had sexual contact with the dog). The mother is fat, and the son is an ugly virgin.
4. By the end, it is revealed that the mother planned to seduce her son and has an extremely strong libido, which is why the father died of exhaustion after so much sexual activity. The son, however, is ideal for his mother in this regard.And the mother hopes that she will be able to give birth to a living child from him.

The search for apocalypse DNA testing death penalty mother son only has three "hits" so: (1) one of them is your story; (2) those words don't all appear in a single part of the story; or (3) the story is no longer on LE. I cannot tell if I found it, Preacher Man has 46 parts. If you think it's #2, then I invite you to modify my search (click on the link and try a different set of words). If you're sure it appears in the Taboo/Incest category, I'd click advanced and search only there. If it's #3, then maybe someone will recall the title and you can find it in the wayback machine.

I hope you find the story.
