Had a random thought that sparked a vague memory, by any chance has anyone read a fanfic where Inuyasha I believe lives in an okiya(possibly, or of some sort of more variation) and teaches women pleasure, and I believe kagome wants him to take her virginity, and then later at some point she buys or try’s to buy his contract so he could be free..he does tell her to leave on several occasions but she always comes back. At the time I read it, it was new, and was very popular, but I don’t know if it was finished.

That’s all I remember lol but it was set in the past and don’t think the future/time travel was written into that fanfic.
Hope this helps
