I think you, your friend, and the succubus should get together for a threesome, that way you can try one out without committing to having your own. It may be hard to get rid of if you summon one and then decide that you don't like her.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
