Great story because it addresses some very real issues.
1. People need more sex than they get and many people are emotionally deformed because of the unnatural lack of sex in their lives.
2. The roll of government should be limited to protecting the innocent. But the issue of incest is a moral or religious issue not a political issue. When it comes to consenting adults having sex there is no reason that the government should have an opinion. So regardless of whether or not a person likes or dislikes the concept of incest it really is not the kind of thing that should be under the control of governments.
Great story and I myself have been wondering how many family members have crossed over the incest line since the Pandemic started . I'm sure many younger , teens especially have since if they were sexually active with a bf or gf can't so they turn to a sibling or parent .
