Saintess Eruna and the Lustful Book of Corruption ~Busty Sister’s H Services~ [Final] [はちからビスケット]

In Urunka village, there’s a busty sister— Eruna.

One day, after receiving requests for assistance from other villages, she left her hometown and went to “Adus Village.”

She was given the task of guarding the “Succubus Rhaenys” who had been sealed in the village cave since ancient times.

Eruna came to the cave and found an old book in the depths.

When Eruna approached, the book suddenly released eerie shine,

and the sealed succubus was freed.

Even though she tried resisting, the succubus still entered her body, almost possessing her.

Eruna was then saved by her fellow sister, Aela. However, the succubus still remained in her body…

Then, to resist the uprising desire under the influence of the succubus, she needs to drink “a special love potion that suppresses the succubus,”

next, she has to endure the horniness, which is the side effect of the love potions, for “Seven Days.”

Of course the perverted men in the village will not let the busty sister have it easy…

Eruna is about to begin her lustful seven days…
