Pa had three sons who courted the girls at the neighboring farm. It was hard for them to pick three out of the five girls to marry. The girls had two sisters left behind so Pa marries both the two remaining girls. (I guess you can do that in fantasies and on scattered farms). Pa had to trade his daughter Annie in marriage to Zeke, the father of the 5 girls. Who gets which girl Pregnant is the essense of the story.
This story was inspired by my wife's teenage son walking into her bedroom and catching her naked (this part is true). The rest of the story is FICTION, in which she proceeds to seduce her son AND his friends....
