[MXGS-1425]

Although my stepfather is usually quiet, only on the nights when my husband is on a business trip he transforms drastically, tormenting me with demon-like fingering and bodhisattva-like cunnilingus, and I spend my days being violently made to cum by his breeding press. Rie Miyagi

Rie was living with her husband's parents. When her mother-in-law passed away recently, her father-in-law, who had been cheerful and carefree, became dark and quiet from that day on, perhaps due to shock. While considering caring for her kind father-in-law, Rie tries to cheer him up by showing him their grandchild's face. However, her husband Shota is somewhat ED from work fatigue, and they can't make progress on having a child. The one who extended a helping hand to the depressed Rie was, surprisingly... her gifted father-in-law. With the death of her mother-in-law, the family's form began to quietly change.
