Hey, I actually have this saved in my files. I've been looking for the rest of it. "Glass no Megami", it's called? Where might I be able to find it?

It isn't from Glass no Megami.

i'm pretty sure that's Aya from the manga, she's pretty recognizable if you read it.

This girl has quite a resemblance to the one girl in Glass no Megami but this page is not in any of the 3 volumes of Glass no Megami

I found out it is from a 210 page book by the name 天使のキュッ (Tenshi no Kyuu or An Angel's Hips) If you look for it on the internet you will find instead a 20 page manga of the same name which is a chapter in this book. The chapter of this book we want is called 悩める果実 (nayame ru kajitsu) which I can't find along with the book in its entirety.
