Limestone and Marble Pie have a secret. That secret is the reason why, ever since the Pie children had been given the chore to watch the farm while the parents went to market, they are the only two that insist on performing these same duties to this day, allowing the rest of the family a trip to town.

The reason is that the two are lovers. And when the family gets back early one day, it is Marble who doesn't want to let that stop their secret couple time from happening. After all, no one else knows how to get her off like her own sister...
