Intro to DDLG?

Can anyone recommend a book where the FMC doesn't know about ddlg or is resistant to the idea at first and MMC can tell she will love it and kind of seduces/coerces her into it and she loves it? Dont mind some mild age play but no diapers etc (no shame, just not my thing!). Bonus points if it isn't contemporary, or if it's at least fantasy or paranormal.
