ALDN-415 I want to impregnate that married woman Jun Suemihiro

A couple who desperately want a child, especially the husband, who is particularly fixated on having one.
At such a time, it was discovered that the husband has azoospermia.
The wife, knowing her husband's desire, couldn't bring herself to tell him the truth.
So the wife decides…to accept the sperm donation from their neighbor who has strong sperm, as if it were her husband's child.
The neighbor agrees to this impossible request, moved by the wife's sincere intentions.
After several trials and errors, the wife eventually becomes pregnant. The husband is overjoyed, and seeing him like that, the wife feels relieved.
However…even after becoming pregnant, the wife and the neighbor continue their trysts.
Was the action taken by the wife truly a happy decision for the couple?
