Saintess Eruna and the Lustful Book of Corruption ~Busty Sister's H Services~

【Story】

In Urcum village, there's a busty sister— Eruna.

She was given the task of guarding the "Succubus  Raynes" 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 aphrodisiac that suppresses the succubus,”
next, she has to endure the horniness, which is the side effect of the aphrodisiac, 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...

【System】

This is a short RPG built around exploration and H events.

At the end of every day, the player must decide to drink/not to drink the aphrodisiac.
Drinking the aphrodisiac will increase “Lust Level,” preventing Eruna from being possessed by the succubus at the cost of being horny and having to resist the sex drive.

Not drinking it will allow the succubus to take over Eruna's body completely. If she keeps that going for several days...

The character has a H status
which will experience changes after H events.
There is also a “Status Message” system for Eruna!

This game features “Lust Level” which increases as time progresses and “Corrupted Level” which increases as H events take place.
As the Lust Level increases, the cap of the Corrupted Level will increase,
making the pure Eruna more and more lustful……!

You can also play as the side character Sister Aela to experience the events where Eruna is not present.

Nothing will happen to Aela if she doesn't go through any H events, but if H events continue to happen to her...?

Not only the cow costume of the childhood playmate, there are uniquely designed costumes!

In this game, the costumes used by each male character have been set, and the characteristics of the costumes will be better used in the H events.
