You know, I actually decided against buying this one because the preview pages were full of those mouths, and made it look like either consensual tentacles, which aren't my thing, or that Aya and Momiji broke immediately, and fuck that shit.
I'm glad someone else got it scanned, though. This one suffers from the mouth issue much less so than the Sakuya book, and is surprisingly good even besides that. Very expressive and involved, and has that two friends dynamic going for it. With the mouth thing in mind, though, I'm not entirely sure if they broke at the end. Sure hope not.
