Ochi Mono RPG Seikishi Luvilias

In a world abruptly disrupted by the invasion of malevolent demons, courageous Knight Luvilia faces off against their ruler, the fearsome Demon King Vois. As he overpowers her in battle, Vois humiliatingly enslaves Luvilia and forces her into submission. Despite her futile cries and pleas for mercy, she helplessly succumbs to the overpowering sensory pleasure that engulfs her. Relishing his victory, Vois indulges in further acts of depravity against other captured women before teleporting away, leaving behind his lascivious team comprising of his younger sister Ilis - a seductive succubus who shares his perversion, and Lufilia - an alluring young witch with ample bosom. Together, they plot their next vile strategy.
