JUR-846 | "Mother-in-law, you want a child, don't you?" While my indifferent husband was away on a long-term work assignment, I was repeatedly impregnated—with his seed deposited deep inside me—by my stepson, Yuichi, who had an insatiable sexual appetite… — Minami Kojima

Minami is married to a man who brought a child from a previous relationship into their marriage. While her husband is supportive when it comes to trying for a baby, their intimate life is cold and purely functional—leaving Minami feeling deeply unfulfilled. When her husband is sent away for a long-term, solo work assignment, Minami finds herself living alone for six months with his son, Yuichi. At first, she views him much like a younger brother, but she soon begins to feel uneasy about his increasingly intense, physical behavior. Unable to resist his direct, uninhibited desires, she finds herself swept away—and her body, long burdened by pent-up frustration, finally surrenders to the long-awaited pleasure.
