Game synopsis

Before Alfredo and Milia, the brother and sister who guard the church their late father left behind, a dark figure wearing the mask of a holy man descends. His name is Rodrigo—arriving to take up the post of successor priest to the siblings' deceased father. This priest, renowned for his many charitable works, has in truth built his position through fraud and embezzlement.
When Alfredo tries to expose Rodrigo's misdeeds, he is instead cornered by the other man, who exploits the forbidden feelings budding between brother and sister. What fate awaits the siblings, pushed into an abyss of lust!?
■ Choose between the violator's perspective and the sister-protecting brother's
In this work you can play either as the brother shielding his sister from violation, or from the standpoint of the priest who assaults the nun. Beyond the pleasure of violating a beautiful girl with raw instinct, you can also savor the masochistic thrill of being forced to witness your sister's violation.
■ Total violation of a pure nun
Set in a church, this work sees the priest—one of the protagonists—and his corrupt colleagues subject the nun to thorough violation in the name of ritual. Enjoy the immoral sex scenes that defile both the church and the nun.
■ Fully animated
This time the animation has been enhanced, delicately rendering the realistic sway of hair and breasts with CG-grade drawing quality, vividly depicting hardcore sex scenes.
