King Gran is a fearsome and powerful incubus who impregnates women. One day, he inadvertently enters the dream of a slutty human named Azu, who inadvertently rebounds his technique and puts a lewd crest on himself!

The lewd crest forces Gran into heat, and he can't stop the heat unless he gets cummed. He has no choice but to be embraced by Azu, but for some reason, the crest doesn't go away...?

The humiliating cohabitation life of the prideful whore is about to begin.
