My harem consists entirely of female demon villains

I, wu Chen, the "hero" of this story, crossed over into a world based on a video game and suddenly appeared in a villainous demoness' bed. If not for the fact that I had married all the villains in the game before crossing over, I'd have been killed pretty quickly. Now, the villains keep pestering me for my hand in marriage and the goddesses are out for my head. What am I supposed to do?!
