Don Bradley is father to a fourteen-year-old daughter, Della. Della's pregnancy causes him to decide she will need to receive her education at home, but while Don can teach her some things (she passed her sex-ed test with top marks!) his sister, Celia, is better qualified. She lets him persuade her to move in with father and daughter, where she'll be available to show and teach her niece almost anything she wants to know.
Don Bradley is a single parent, loving father of Della. She is young and beautiful, he hasn't been with a woman for four years. Della, at fourteen, is feeling the need to explore her new, untried sexuality. There's her boyfriend, Ronnie, of course, but she thinks there's someone better to show her. He does it so well Della has to be home schooled.
Don Bradley isn't sufficiently qualified to educate his 14 year-old daughter, Della, at home - a situation he sees as desirable in view of her advancing pregnancy, but fortunately, his sister, Celia, is. Trouble is, Celia demands a price, but it's one Don doesn't mind paying.
In the third story in the 'Home Schooling' series, Della Bradley gives birth to the daughter she and her father made, while her Aunt Celia contemplates her own forthcoming confinement, and accepts a heartfelt apology from her brother, Don. His method of apologising appeals strongly to her.
Della's home with her new daughter, Susan, and Don, father of both of them, invites his Aunt Grace to help out with the housekeeping, because his sister, Celia, is herself away giving birth to their son. Grace brings her son, Joplin, with her. He turns out to be Don's son also. Soon both men and both women are enjoying sexual relations with each other, and the consequences are just what you'd expect.
