"This is what losers get", said Buffy in delighted good humour, and planted a firm smack right in the centre of Willow's bared behind. Willow flinched and gasped, but it wasn't a hard smack. Buffy delivered several more slaps, also calculated just to sting a little.
"Aww, does that hurt?" said Buffy in a heavily ironic tone of mock concern.
"It's like a (oww) melodrama where the (gasp) blonde villainess torments the (eek) red-haired heroine."
"Are you calling me the villain?" demanded Buffy, grinning at Willow's red hair which was just visible down near the floor beyond Buffy's left thigh. "How many times have I saved your life?" Smack! Smack!
"OK! Yeow! I was just using poetic licence."
"Well to finish, I'm going to give you some hard spanks for your ingratitude."
