Before I start talking about this hentai manga in particular, I wanted to mention that we also share a full color version of Fairy Bitch Lucy on our site.
Except for the coloring, there is no real difference between the two versions. Some prefer it white/black (standard manga style), others love the colors while watching their anime heroes getting banged. The plot stays the same and so do the hot sex scenes with Lucy as the main porn actress in this doujinshi and Erza and Mirajane as the secondary role characters (only present on 1-2 pages).
“Reviving the man with a kiss and a handjob. It’s finally the fun part! Okay, you are recovered, now give this mouth your cum next (Lucy says this while pointing at her pussy).”
