Seegee:
I'm a big fan of Buffy the Vampire Slayer. There's an episode in the 4th season of the show called 'The I in Initiative' I think. Anyway that episode has long been debated by people as there are 2 spanking references in it. One is of Anya cheerfully admitting that she and boyfriend Xander have tried spanking as a sexual thing and the other is when partnerless Willow wistfully muses that it looks like everyone but her is getting spanked.
IIRC Willow made a reference to Buffy being rather scarce (hard to find) lately because she had a "spanking-new boyfriend," whereupon Anya announced that "We've enjoyed spanking," referring to herself and Xander, who was also present.
Shortly afterward, Buffy and Willow were standing together and talking in the cafeteria, watching while Buffy's new boyfriend (I don't recall his name) was going through the food line across the room. Upon seeing him select some less-than-healthy choices of sustenance, Buffy muttered "Oh, he's going to be so punished," after which Willow plaintively noted that "Everybody's getting spanked but me."
I'm guessing that Anya and Xander 'switched off' in their spankophile frolics, and after all Anya was originally a 'vengeance demon' whose purpose was to punish males (albeit considerably more severely than merely paddlng them) who mistreated females. She might still have had a touch of that desire even as a reformed former demon, and Xander certainly deserved to be disciplined on numerous occasions--especially when he lost his nerve and left Anya standing alone at the altar on their planned wedding day.
Hopefully, Tara put Willow across her lap and tanned her soundly once they'd become lesbian lovers...
