The Sacrificial Maiden Corrupted By Coupling With An Oni

[Synopsis]
A lone and willing girl, chosen as a sacrifice by the people of her village.
It was an attempt to appease a beautiful yet fierce demon god.
Our heroine, though prepared to be devoured, suddenly found herself living in the god's mountaintop home... (Albeit, with a few conditions.)

For ten years, the pair lived peacefully together as a sort of family. The god had raised her, protected her, and so she had grown to trust him completely. But one day, a traveler arrived on the mountain... and something the traveler mentions leads the girl to break one of her promises...

The promise that she'd never set foot off the mountain.

"I did not raise you to be a naughty girl who does not keep her word..."
"If only you'd been a good girl that does only as I command..."
"Then you could have continued to enjoy a gently warm and pleasant life."

This sent the god into a rage. He hadn't raised her to disobey him. How could she do such a thing? In his mind, there was only one thing to do now... And she was about to discover just how deeply-rooted his affections truly were.

"Even though I love you so dearly!"
"I want to ruin you... to devour you..."

The protagonist, who had never known of doubt or needed to distrust others,
is enveloped by a torrent of obsession from the one she thought was her family.
The two fall... together... drowning in debauched and abandoned pleasure...
