Recently I've been interested in doing a roleplay involving a sort of apocalyptic scenario where all men, save for my character will have died or disappeared. The general premise is somewhat like Y The Last Man with more adult themes of course.
This idea is only really an outline so far as I prefer working out the details with an interested partner so it's not so one sided. Pregnancy and your character being some sort of "leader" in the new world whether it be President, Mayor of a town or some type of newly elected representative.
As I said before I'm looking to include pregnancy, and have my character be protected as the last man alive, but also treated as a sort of prisoner. It would be great if other less vanilla kinks could also be included, but that can be worked out if you're interested.
Feel free to PM me if you're interested in the premise, it's all open to change and preferences.
