A man living in Adachi Ward, Tokyo, has been married for three years with no children. His wife, known as Mihoto, has beautiful breasts and an intensely captivating reaction during sex—her body writhing in ecstasy, convulsing as she gushes large amounts of vaginal fluid. He first met her at a friend's birthday party, where her stunning beauty and graceful, demure presence drew other men toward her, leaving him with little chance to speak to her. Later, he was shocked and filled with mixed emotions upon learning she was already married.
