A/N: You know, I absolutely hate the process of posting things on ff dot net. It's impossible for me to write a decent summary, and they screw my formatting. No spacing allowed, no tabs, no backslashes in the summary... Eh.

Silly stuff, for slashthedrabble. The first thing I've written in more than a month, so I'm feeling pretty rusty. C&C is worshipped shamelessly.
Pairing: S/X

Words: 500
Warnings: Not really. Slash, obviously. Umm, a bit sappy?

The second he caught sight of Spike, cherubic innocence radiating from every line of his body, all of Xander's suspicions were confirmed. His finger descended to stab out at vampire's chest in flustered accusation.

"You knew! You… lied, and you …You!" Spike, who had dropped all pretence of who, me? in the face of Xander's righteous wrath and was now smirking with unabashedly evil glee, only ducked halfheartedly when the boy lunged at him from the doorway, the two of them shortly ending up in a tangled mess of limbs on the kitchen floor. The following scuffle was quickly ended by Spike's complete inability to control his laughter when Xander's fingers stabbed mercilessly into that soft spot behind his knee.

"Oi… Christ! No fair… playin' dirty, white hat…" He wheezed out between the completely un-vamply giggles that continued even after Xander had moved both hands up to pin his wrists to the floor. His captor looked down from his seat directly atop some of Spike's squishier organs, astonished.

"No fair? Am I offending your sense of honor now? You just let me- nay, instructed me, even- to walk in on Giles and—" Spike started snickering quietly, interrupting Xander and earning himself a sharp blow to the shoulder. "I'm never gonna be able to look him in the face again, you jerk! It's so not funny."

"Beg to differ," muttered Spike, this time getting a jab in the ribs. "Ow. That's domestic abuse, that is," he complained mildly, wiggling in protest under Xander. Under certain parts of Xander that had already begun to show some interest in the proceedings. Noticing this and characteristically pressing his advantage, he looked up through his eyelashes with a carefully calibrated smile. "Come on, luv, it was just a bit of fun. 'Sides," and this time a much more pointed wiggle, "got me where I wanted to be, dinnit?"

Xander looked incredulous. "You made me walk in on Giles and his girlfriend to… what, get you sex? Do you realize how not sexy it is to see your father figure doing the really really nasty?"

Spike rolled his eyes. The boy was so hopelessly vanilla. "Missin' the point. Yeah, I lied. So, question is now…" He rolled his hips slightly, gratified at the visible glazing-over of Xander's eyes, "How're you gonna punish me?"

Those eyes widened, then narrowed with lust as Xander caught on. "Oh, so you are still evil. You know, I'd started to wonder…" It was Xander's turn to laugh at Spike's faux-injured look, his anger melting into something... nicer. And then his warm mouth was on cool skin, nipping a little harder than usual- Spike's lips moving on his ear as he released the wrists, freed hands drifting down to instead pin the vampire's hips to the floor.

"Would you love me more if I was pure and true, and honest all the time?"

Xander considered his answer, still feeling a little annoyed. "Maybe," he tested.

Spike smiled against his neck.

"Liar."
