I wish he would do more rapey stuff like this 8p. I love his art tho. This needs a translation like "Shake the Fake"...
I actually tried to translate this doujin for myself once...from what I got (there is a lot of shaky text), they are trying to breed the goddess "Athena" genetic line with humans. That dude is a lucky bastard tho, who gets to rape the shit out of her 8).
