Geoffrey:
I have to say that as this thread appears on the Library of Spanking Fiction, we can confidently assume that no real daughters' bottoms are being injured.
I disagree, the OP went onto explain how he is in a form of domestic discipline dynamic and the comment appears in the smalltalk section of the forum, rather than as a story. Not all discussions in the smalltalk forum relate to fiction or fantasy, and indeed a number of people come here for real life advice.
transmanspankee:
Your fetishistic language when discussing your daughters ("large well upholstered bottoms") concerns me deeply.
Like transmanspankee, I think this form of comment about underage children in the context of spanking is quite concerning and is formulated very inappropriately. Spanking should be left as a consensual activity between adults only, and is never appropriate as a method to discipline children.
markuk:
Perhaps if I was to put my question in a different way so as not to offend some people. If I was to write a story about a father with a wife and two daughters ages 16 and 15 (all with large round feminine bottoms).
This would be less concerning, but you deliberately chose not to ask the question in this manner at first instance.
