Erin and Jason, the 12- and 13-year old children of the Walton clan go off to a field and watch horses copulate. They marvel, and Erin tries to get Jason to explain the process to her more clearly, but Jason doesn't know much himself. Eventually they experiment by examining Jason's sexual anatomy and then Erin's; and after that Erin suggests that Jason and she might want to imitate the horses. They quickly discover the missionary position, which they prefer to horsy style; and soon they are having sex regularly. Then one day their older sister Mary Ellen catches them in the act. So Jason fucks her too - after Erin primes her, of course. A prologue tells us that eventually the rest of the kids join the fun as well.
This is an interesting story about kids having sex with each other on the farm; and I guess it's fun to associate the activities with the various Walton kids. I have trouble with parodies, however, when the people get too far out of character. These kids all behave as if their irresponsible parents have taught them nothing about sex. I have an overwhelming impression that the parents and grandparents in the Walton series would have done a better job of raising their kids.
