Okay, that's good. Most of my stories were set up for the rules of sites that allowed fictional characters as young as 13. I live in Japan, and that's the national Age of Consent here.

The Erotic Mind Control Story Archive sets it as 13 as well. So does AdultAnimeRoleplay amnd some other sites that I've been a member of. Elliquiy has a limit of 16 (it was 13 before, but that was changed). Literotica has it at 18, but that's only because of where their servers are located. The Grey Archive doesn't appear to have any limit at all that I know of.
