Maou ga Nokoshita Kokuin ~Kijou to Iu Na no Iki Jigoku~

The defeat of the demon lord was just the beginning, and the real adventure started on the way home...A party of three beautiful heroines take down the demon lord, but not before it curses them with an emblem of lewdness.The mark fills them with insatiable lust, and all reasoning is lost as they take on all comers!Even with the strength to destroy the demon lord, by the power of the lewd emblem, they are simple sex-seeking girls.No matter how filthy they find it, the pleasure drives them to corruption.[From Dlsite English]
