Age Play

[Lexirific]

Once I am up to date with writing up my adventures, I'm thinking of starting an ongoing roleplay story based around a young, impressionable schoolgirl, which I will try to use as a basis for a story I write on here. Obviously roleplaying it in game as a 16 year old is generally considered fine, but if I want to post it on here, am I best keeping all characters aged 18 or over? Or would it be okay with a disclaimer? Lowering the age a little just allows for a lot more development within the story.
