My First facepalm in f95 was for you.Being pregnant with another man while in NTR is not heavy NTR but wholesome NTR. The reason is that the purpose of sex is to multiply. If you get pregnant by the product of your fetish/kink, it means they have a good relationship with one another.
Bullshit only.
I agree that we could think in some scenarios for the future. And I agree that pregnation is one possibilite, because many guys like this Idea. But I really don't know how much people wants an extraconjugal pregnancy. Being honest, I think we should have 2 or 3 routes: Nat over Control; Nat in Control; Nat cheater. I dont know If pregnancy is the best finish for any of these paths
