Cult Of The Serpent: Cuck Or Be Cucked

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.
