A Give Away Scenario
The only real challenge in this scenario is coming up with a reason why the girl is this permissive in the first place while still keeping the story interesting. The girl's resistance will be fairly minimal to the point it is harder to get a "bad end" (although, it could be fun to include bad ends anyway just for those who want to accept that challenge.) Maybe it's the MC's daughter and the mother is 100% on your side, maybe you're a foster father of a girl taken from her "sexually abusive" father who has already groomed her and she enjoys it and is sad he's gone and she's not getting it anymore. However it is, keep the characterization somewhat believable at least.
NOTE: (The purpose of this category is really more to allow the author to move scenarios from "very easy" here if they wind up being too easy even for that category.)
A Very Easy Scenario
The MC has the girl more or less isolated in some way, there is nobody she even has the chance to talk to in order to verify whether what she is hearing is right or wrong. The girls will tend to be on the younger side, usually toddlers or young children. If the MC is a younger teen, the girl can be as old as 10 and still warrant a "very easy" rating due to them being at a sexually exploratory age and also likely to look up to an "older kid" and go along with what he is saying. These factors will all lead to her having a lot less resistance to the MC.
- Communication issues You were adopted by parents from overseas 10 years ago. Your adoptive parents have recently decided to adopt a little girl who is also from your former home country, and right now you are the only one who can communicate with her.
An Easy Scenario
Something about the scenario will make the girl feel she can't tell an adult about anything that happens, and she is likely eager to please or otherwise does not have a great deal of resistance to the MC's sexual advances. They will offer some resistance though, and will need the MC to work on them a bit.
A Standard Difficulty Scenario
The girl will act like a fairly normal girl. They will either have some kind of connection to the MC which will mean the MC does not need to work in order to earn her trust, or she will be vulnerable in some way due to neglect or abuse at home, but she will have a standard level of body shyness and "good touch/bad touch" awareness that has to be worked past. There may or may not be something in the scenario that makes the girl hesitant (but doesn't feel completely unable) to tell other adults about what you are doing with them.
- Lonely girl at the park A latchkey kid who's single mom often works late is told to go straight home after school, but instead she often goes to a local park along the way that is not really frequented by other children at that time. This is where you encounter her.
A Hard Scenario
A second adult is readily available for the girl to talk to, there are multiple girls, the girl has an above average resistance to sexual advances, or the MC is a complete stranger to the girl. Any one of these things could be true, and there may be a bit of mixing.
A Very Hard Scenario
Every possible factor that could make things more difficult for the girl's grooming may be included. These scenarios present a high degree of challenge.
An Impossible Scenario
This is more of a category for "Very Hard" scenarios that were made too hard by the writer. There is no route, or almost no route, on which the girl will accept sexual interactions, and the MC will have a fairly difficult time raping her and getting away with it.
