I highly recommend purchasing this work! You can listen along to the songs translated here, and use the extra translations provided to enjoy the charming character commentary the accompanies the guidebook and character introductions (translations for character introductions still to come).
The work also includes versions of the songs for each character, and alternate versions done while performing fellatio and handjobs!

Did you know the grown-up teacher stammers whenever she says "dick"? Or that Hajime uses "boku"? Getting the full version from DLsite is my highly recommended way of getting the full experience and seeing all the little charm points put into this very detailed work!

Section 1: A guidebook the character's bodies
Section 2: Song lyrics.
