Wife Eater - Mature Body and Immoral Village

"For three years, you must not refuse the advances of any man in the village."
Misa's father-in-law's words flashed back in her mind as she heard his wild breathing and panting voice coming from the other side of the shoji screen.
Misa has been forced to live in extreme poverty due to her ex-husband's debts, and a few days ago she remarried and married into the Zaizen family, a landowner in a marginal village deep in the mountains.
Just as she was excited with happiness, she was informed by her father-in-law of a terrible custom.
He asked her, "How does that feel?" "Yes, Father-in-law...."
Misa came back to herself at the sound of her father-in-law's and sister-in-law's voices.
Once she had prepared herself to sacrifice herself for the sake of happiness, but the horror that loomed over her made her feel as if her whole body were frozen.
