ALDN-432 I want to get that woman pregnant Rieko Hiraoka

A couple desperately wants a child, especially the husband who is strongly attached to the idea of having one.
The husband's azoospermia is discovered at this time.
Knowing her husband's feelings, the wife cannot bring herself to tell him the truth.
And so, the wife makes a decision...to accept sperm donation from their neighbor who has strong sperm.
The wife's sincere wish prompts the neighbor to take on this impossible consultation.
After several trials and errors, the wife eventually becomes pregnant. The husband is overjoyed, and seeing her husband like this, 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?
