Age is relative. Contrary to the usual story of a young girl and an older man, this relates to the strange relationship between and older man and a much, much older woman. It also relates to what makes some people tick, and how denial may allow for things that could never be otherwise
Almost 40 years ago, our hero found a small Appalachian town where all the women had recently been blessed with bigger breasts and the men had become sterile. What did our hero do? Starts with minimal sex. That will change as as the story continues. (Tags include action in future updates)
While enjoying some pot, our young hero's aunt, mom and grandmother come onto him and all get knocked up; then his sister also gets in on the action. Pregnant sex and four deliveries follow.
