Higurashi - When They Cry Kai: Tsumihoroboshi

He no longer gets excited by sex with his beloved wife.
Fujio Takahiko realized this about himself on the night of their second wedding anniversary.
He had always thought of himself as being rather indifferent to sex. But he vaguely realized that the real reason wasn't that.
Soon after getting married, Takahiko began having dreams. The same ones, over and over again.
--The lewd customs of the village where he was born and raised.
--A banquet held every night during the summer festival.
--A female and male writhing and panting in the darkness. The vulgar fragrance produced by animal-like sexual intercourse.
Unable to bear the sheer horror of the customs, he fled his hometown.
Takahiko realized that the religious rites held secretly there had planted an indelible sexual inclination deep in his heart. As he gazed upon his wife, Manami, sleeping with her ripe beauty and adorable face, Takahiko felt a dark heat building up in his erection. And he knew that this heat could only be quelled by returning to his hometown...
"Kagachi-sama... I offer you comfort."
The words spoken by the lips of the woman he admired came vividly back to Takahiko's mind.

Haruki and his wife Nagisa go to a hospital in Tokyo for fertility treatment. They are told that there is a village known for helping in improving fertility.

The village was rich in nature and seemed to be the best place for them to heal their minds and bodies. There was a rumor that they would be blessed with a child, so they moved to the village and started their new life.

A few days passed after the move, and Haruki had returned to work, Nagisa was asked by the village chief to help him with the cleaning, so she went to the chief's mansion alone.

When she was taking a break from cleaning, the village chief sexually harassed her about having a baby, and when she was about to leave, he kissed her forcefully and raped her.

The reason this village is so fertile is because the women who live here are raped and impregnated by the whole village!

Will Nagisa be able to safely give birth to her husband's child?
