Really Good Neighbors (Foursomes For All #2)

Liv becomes friends with her neighbors Mac and Curtis, who have returned to their post-graduate studies after losing their wives to a drunk driver. Over the following months the friendship evolves to one of mutual respect and tenderness. Eventually the men ask her if she would like to pursue a romantic relationship with either one of them. Unable to choose between them, she chooses both and they form a stable, loving threesome.

When an influential member of the community comes to suspect the public relationship of the three goes deeper than mere friendship, the threesome decides they need to make their threesome a foursome with the addition of another woman.
