That first page is one of the boldest depictions of a pussy in manga that I've ever seen lol. So delectable, so tastefully racy.
I was internally screaming at him to grab her ass with both his hands before he did it, so when he did, I felt the author's vision align with my own lol. Too bad he won't let the Assistant Masami-chan get the same sexy treatment as Sensei though, poor girl gets cockblocked at every turn ðŸ˜
