A spanking must be at least six purposefully delivered smacks to a freely offered bottom.
The ideal spanking is given by hand to a bare bottom, although implements are acceptable, knickers need not necessarily come down, nor clothing be disarranged at all.
A girl's name can be her birth name, one by which she is generally known, or the name by which she has presented herself. Titles, epithets and surnames do not count, nor anything obviously spurious.
Each spanked girl can count only once, although she can be included under any permissible name, not only the one she was using when spanked.
A spanker must not give a girl a name for the purposes of gaining a letter, nor instruct her to name herself, although cunning ploys to ensure that a girl goes under a particular name are very much in the spirit of the challenge.
The gender and sexual identity of those spanked is a matter of personal choice so long as it meets with the spirit of the challenge and does not infringe the other rules.
Paid spankings are acceptable, but not quite the done thing save in extraordinary circumstances such as travelling abroad to secure a rare letter, or perhaps bidding at a charity auction.
Spankings must be real, involving actual smacks delivered to real flesh by the spanker. Proxy spankings, self-spankings under instruction and all forms of virtual spanking do not count.
Spankings should be given, and taken, for pleasure or for agreed discipline between consenting adults.
Thus are the rules and ideals for these 26 beauties who bend their bottoms!
