As Charlie films in and around Madrid, Craig and Lydia join him, along with Craig's adored and adoring nanny, Maybelle. All seems to be going smoothly until Lydia and Charlie have a minor disagreement about building a treehouse for Craig. And Charlie must warn Lydia - as part of their spanking contract - to leave the project to him.

Within days, a heavy rain comes and Lydia worries the raw, untreated wood of the treehouse kit will be ruined. So she makes a fateful decision about the kit that puts them cross-wise of each other when he returns to the villa. Then Charlie brings home two of the Andalusian horses featured in his movie, so he can train with them. And soon finds Lydia, an unskilled rider, up on one of the horses in the exercise yard, never mind their spanking contract says she must only ride horseback accompanied by a skilled rider.

Note: This book contains vivid descriptions of sexual activity, domestic discipline, the spanking of an adult woman, anal sex, and anal discipline. If such scenes offend you or trigger you, please do not purchase this book. In addition, the series is also about two young, devoted married people growing and maturing together over the course of multiple story lines; they are flawed, loving, devoted human beings, and therefore make mistakes they try to correct. If you are looking for perfect people, look elsewhere. Finally, please note: Any resemblance to real people, living or dead, is unintended and coincidental.
