Strong-Willed Busty Elf Marked with Pleasure Runes and Cuckolded

A fantasy game set in a world of swords and magic. After the protagonist and their companions—the elf Til and the middle-aged Flurio—defeat the Demon King and his armies, the protagonist and Til become lovers. However, when passing through a town, Til is marked with a cursed seal that gradually overwhelms her with pleasure and desire. Three men—the former ally Flurio, a boss goblin, and the former enemy Casper—appear and begin to exploit Til's condition. The game follows Til's corruption and the resulting non-consensual sexual situations.
