The thing is, I'm disappointed with this installment. There's no actual sexual contact, and it just seems to be a vehicle for the artist's fetish for mantits. Parts 1 and 2 didn't have any sex because they were establishing the plot, Part 4 was mainly a gaiden book with no sex but erotica, and Parts 3 and 5 culminated in sex to wrap things up. I suppose the previews just got my hopes up or something. At least according to his Patreon survey I'm not the only one who's annoyed with the lack of sex to make room for breast expansion, so I'm praying that Part 7 will be better in that regard
