Seegee:
There were a few spankings and bondage references in Wonder Woman, which I believe was the creators way of thumbing his nose at the comics code in place at the time and seeing how far he could go before they realised what he was doing.
There was one "Wonder Woman" comic book in which the full-page opening panel showed the heroine in the classic OTK position, bottom upturned (although of course not bare) atop the lap of a very young girl who was eagerly wieldng a quite solid-looking hairbrush. Numerous other extremely youthful (4-6 years old or so) children were watching Wonder Woman's spanking, but her expression was rather placid and even slightly amused. That story's title was "The World of Children" or something like that, indicating a society in which young children were in control.
Wonder Woman possessed a magical golden lasso that forced anyone encircled by its coils to truthfully answer her questions, so IMHO she was 'into' bondage and psychological dominance rather than spanking. However, as I did express in a couple stories, AFAIC both Wonder Woman and her younger adopted sister Wonder Girl (the original one in "The New Teen Titans" comics) would be appealing fantasy spankers of super-villains.
Power Girl would be my favorite superheroine disciplinarian although Emma Frost, the White Queen in Marvel comics, wouldn't be at all bad either. For a 'good guy' being paddled by a super-villainess (which the White Queen supposedly isn't any more), I'd find it intriguing to go over Mystique's knee... --C.K.
