ALDN-432 I want to impregnate that married woman Rieko Hiraoka

A couple desperately wants to have a child. The husband in particular has a strong attachment to children. At that time, the husband is found to have azoospermia. The wife, who knows how her husband feels, is unable to tell him the truth. So the wife makes a decision... to receive sperm from a neighbor, whose sperm are strong enough to be the husband's child. The neighbor, impressed by the wife's sincere feelings, accepts the impossible proposal. After much trial and error, the wife eventually becomes pregnant. The husband is overjoyed. The wife is relieved to see her husband like that. However... the wife and the neighbor continue to meet up even after the pregnancy. Is the wife's decision really a happy one for the couple?
