Searching for a title

Is this a good place to ask if anyone knows the title of a of an NTR doujin that I read years ago? It popped into my head a while back and I've tried to find it but so far no luck.

The plot goes a little something like this:
There's this boy who likes a girl and they both live in a village away from the city. The boy has an uncle who went to live in the city years ago but now has come back to get married. Unfortunately for the boy and girl the village they live in has an old tradition where young women have to marry older men in order to ensure that they produce children. So the reason the boy's uncle has come back is to get married to the girl that his nephew likes. We also learn along the way that the uncle liked a girl when he was young but she was forced to get married to another man and eventually had a baby girl. So the uncle waited until that daughter had grown up in order to marry her. Which he did since that daughter was the girl that his nephew liked. In the end the boy watches his uncle and his wife name their newborn daughter and vows to marry her when she grows up just like his uncle did. The girl has short hair and wears a kimono if that helps.

Anyone know the title to this one? Thanks.
