Girls Saurus DX is the weird sequel to the equally weird Girls Saurus, a bizarre manga about a female-phobia protagonist who sees other men in female forms. I thought it was pretty weird, until I remembered all the awesome gender swapping characters from other ecchi series like To Love-Ru, etc.
In both this manga series and its predecessor, nudity is intended to make the readers uncomfortable, much more so when grotesque fat-ugly-girl nudity is used, which did not make this compilation. Like I said, weird manga. Still, one way or another, this series still gave us boobs to look at.
Girls Saurus DX (10 volumes, complete)
There are some additional non-nude picks in the rar file, located in a sub-folder.
