WBWP/Your partner's parents
We ought to talk about your partner's parents in all of this. If they are going to be doing stuff with you, it begs the question as to whether or not there will be disapproving parents nosing in that you have to hide things from. If you do not specify anything, I will assume your partner has both of their parents, but they will always be off scene and talked about as little as possible. This, however, can get a little weird so it might be best to get some detail in about them.
NOTE: It is technically possible for YOU to be your partner's parent. She can be your daughter. However, since your current age setting lists you as having somewhere between a 1 and 3 year age difference between you, it would mean she was conceived when you were 2 at the oldest, so that would be some ridiculous precocious puberty (but not unheard of.) Of potentially less importance is the fact that you are also still a virgin, although I suppose I wouldn't expect a 1-2 year old to be having PIV sex.
At any rate, are you her father?
If you don't pick one of those two, I am going to assume the answer is no, that no ridiculous situation like that occurred. That being the case, let's move on to talking about your partner's real parents.
