This is most likely super prone to NTR...Haaa...It's too much...I feel like dropping this...as i progress and continue reading this...I can only feel that the NTR vibes is getting stronger...Besides she mostly thinks only of Erotism which is on par on being a (Sorry for the word but i can't think of any other word) "Slut" (Let me explain why: She only thinks of doing erotic stuffs and even going far into attending an r-18 cosplay event, It may be just a hobby but it's not normal if you think...Plus, Doing erotic stuff is Turning you on which may lead into a sudden burst of lust thus resulting into something that can be Sex or something...) Boi you should stop your feelings and kill it...You experience how cruel world can be so better be safe than sorry.
