If three is a lucky number, then four must be...

"What happened to the other Willow?" asked Buffy. "She looks like she's trying to say something but no words are coming out of her mouth."

"Who knows?" asked Anya. "Anyway, if there's no problem with the wish, then I guess Hallie's work here is done. Let's go, Hallie."

"Okay, Anyanka," said Halfrek.

"Just a minute," said Dark Willow. "I just realized something."

"What's that?" asked Anya.

"I never taught Buffy here what a threeway is," said Dark Willow.

"Well, that's nice," said Anya. "You'd better teach her that, I guess."

"Wait a minute," said Dark Willow. "You're not shocked by the implications of that statement?"

"Heck, you and Buffy are both over eighteen," said Anya. "Why should I care?"

"So you really aren't shocked, are you?" asked Dark Willow.

"Heck, I'm an ex-vengeance demon," said Anya. "I've been on this earth for over a thousand years. There's not much you humans have done sexually that I haven't seen at one time or another. Though come to think of it, I never tried a threeway myself."

"Wait a minute," said Dark Willow.

Anya started to take her dress off and said, "Hey, it sounds like fun. Want to join in, Hallie?"

"Not really, Anyanka," said Halfrek.

"Oh, pleeeease," said Anya.

"Oh, why not?" asked Halfrek. "You only live once."

And with that, she proceeded to take off her own dress.

"Wait a minute," said Dark Willow. "I didn't invite both of you."

"Of course you didn't," said Anya. "That's what makes it so fun. I could use a break from Xander anyway. And I just knew something like this involving me and Hallie was inevitable. It was only a matter of time."

"But still --" said Dark Willow.

"Oh, I wish you'd just shut up and kiss me, Dark," said Anya as she unhooked her bra and took off her panties. "And then I wish that you and Buffy would just go along with whatever I and Hallie say."

And before Dark Willow could say or do anything, Halfrek said, "Wish granted."

Twice.

Anya then smiled and asked, "Now which one do you want first, Hallie? The blonde or the brunette?"

"How about both?" said an equally naked Halfrek.

Anya and Halfrek just looked at each other, smiled, and said, "Wish granted."
