Probably the main reason why I purchased the book (tied with the fact that it was BlackFriday and it only cost me $4,95 yay!).
I love Teacher-student relationship and this is one of my favorite kind : male teacherXfemale student, vanilla, non-harem/non-group and not the fake teacher kind (tutor...grrr...more like traitor, there's nothing forbidden about that! where's all the fun?) Add to that a dash of shimapan, a zest of natural-sized breasts and an amazing art-style and you get yourself pretty much the perfect hentai in my book!
Anyway, I would love a sequel where struggling to keep their relationship a secret.
