A succubus mark...When could this have been placed...? I should've been able to notice a disturbance in my magic if a succubus mark was being put on me...Did I feel anything strange happen yesterday?Mukyuuuu?Yesterday... Umm...Obviously I read books.But there weren't any grimoires that I felt strange magic from.After that was a bath...There shouldn't have been anything strange then as well.And after that was more of the norm—I supplied Koakuma some of my magic—※She is supplying magic to her familiar.Since it's on my chest and not my womb, it doesn't raise my reproductivity but makes my chest more sensitive? Please don't make me lactate...
