I married Satoshi three years ago and have lived with his stubborn, old-fashioned father ever since, but we have never grown close. I also struggle alone with his demands for an heir and my husband's habit of finishing sex too quickly. One day, after trying for a baby with my husband, I run into my father-in-law in the shower. He says he knows his son cannot satisfy me, then reaches for my sexually frustrated body... This is an adult in-law role-play.
