Step Brothers Or Lovers?

a/n important

I will be updating chapter 5 later on just wanted to let ya know I'm thinking on making another story here are my Ideas

1) prince sasuke is spoiled and wants everything and sees naruto with his girlfriend and claims he wants naruto as his husband but naruto's girlfriend isn't having it (narusasu story naruto seme sasuke uke)

2) (idk I couldn't decide) either naruto or sasuke has the mind of a child but a body of an adult and either sasu or naru is a yakuza and is married to the other one but someone tries to still them away from his husband. (Who should be the Yakuza seme and who should have the mind of a child?)

3) sasuke is in a abusive relationship with his cheating husband naruto and is depressed and suicidal but gets pregnant with Naruto's baby's only problem is naruto didn't know he was pregnant and thinks sasuke cheated on him so he wants sasuke to get rid of the baby but sasuke refuse and try to prove its Naruto's baby.

4) It's a world where anyone can get pregnant male or female and some people is a hybrid of some type the hybrids has a mark they get which is called a mate mark and they go to a hybrid only school to find there mate but if there mate refuse them they die. ( I could make it vampires instead also)

5) Males and females get pregnant sasuke goes to a school for rich people but only got in because of a scholarship cuz he and Itachi isn't that rich but sasuke has no idea of what having fun is he doesn't have friends he doesn't go out and have no phone or freedom Itachi tries to keep him safe so sasuke has to go to school and straight home until one day sasuke spaced out made a wrong turn and walked into the bad neighborhood and meets a blonde boy who might change his life forever.

So which one should I do? Let me know..
