I don't care to see anyone under age 18 involved in spanking stories, but it's because such stories are, for me, a form of pornography, something I seek out to fire up the passion. If I start reading and find children in the plot, it sort of kills the mood.

In this particular case, it's the full nudity which is the problem. A father who actually did such a thing could conceivably be prosecuted for a sex crime, -especially- since it is a stepfather and not a natural father, i.e. one who has not raised this girl from infancy, but has just now stepped into her life as she is starting to blossom as a woman. Ew.

As someone else stated earlier, if there are underage characters, make sure there is absolutely no sexual undertone whatsoever, strictly discipline. I wouldn't even include such a thing in the contract. It's not realistic, but it is icky.

If the girls on the receiving end of the contract were over 18 and gave consent of their free will, that would make a difference.
