I want to get married! Shall we begin with sex?

Fine, a young noble wife, sets out to investigate the “magic stones” causing a stir in the kingdom on behalf of her husband, the feudal lord. However, her lonely married life with her busy husband has left her body frustrated and filled with overwhelming desire…!!
