tag older male younger female
Tag description The male(s) in the story is/are noticeably older than the female counterpart.
note While you can search for this relation with tags like dilf, old man etc. and look for a story with younger female, it would be more practical to have a simple tag defining the relation in the story. The use of "female" is deliberate as it defines an adult female instead of a young girl (loli).
