Hachikara biscuit/Yuraribbon Games released a new game called Saint Elna and the Book of Depravity ~The Sex Duties of the Busty Sister~ and the version is 1.03_MOD1. The game’s story is about Elna, the busty sister of Ulunka Village. One day, she receives a request for assistance from another village and sets off for “Adus Village,” far from her hometown. There, she is tasked with watching over “Lenis the Incubus,” said to have been sealed in the village’s cave since ancient times. Upon visiting the cave, Elna discovers an old book deep within. As Elna approaches, the book suddenly emits a strange light, and the sealed incubus is inadvertently released.
Despite struggling against its immense magical power, Elna is almost possessed by the incubus. She is saved by her fellow sister, Aira, and escapes danger, but the incubus remains inside her… To counteract the overwhelming lust caused by the incubus, Elna is told she must drink a “special aphrodisiac to suppress the incubus” and endure the resulting sexual desires for “7 days.” The lecherous men of the village, starved for women, will not leave the blushing, busty sister alone…
