A sponsored Spank-a-thon is a good idea!! I think maybe Her Pinkness would be a most deserving candidate for this great honour! Not only is she most deserving but she would present a supreme test for any spanking machine!! Perhaps it may be best to have TWO machines because of the vast area involved!!
One for each bumcheek, hmmmm?
Well, Arthur, *IF* your occasional photographic depictions of PinkAngel's derriere are truly accurate, you might want to also have backup attachments--paddles (narrow and wide, wooden and lexan for each), straps (leather and rubber), tawse, crop, cane, etc.--for each spanking machine, in case her opulent posterior ends up wearing out the original ones before they've had that much of an effect, punishmentwise.
Given your silver-tongued powers of persuasion, I'm figuring that you'll eventually win the young lady's cooperation with this scientific study--so I'll be expecting a detailed report (complete with color photographs, of course) to be posted in the Library at some point.
The best of luck to both of you... --C.K.
