Backfire - Spander Files

The command was such a shock that Spike did what he was told.
Xander removed his hands from his pockets, straightened his back and sauntered
over to Spike with unexpected grace and glide.
He smoothly climbed onto the bed, straddled the outstretched legs and settled back
to sit on Spike’s thighs. Spike kept his hands on the bed, fearful to touch the
inviting body.
He couldn’t read Xander’s expression. A blankness was in the boy’s eyes that
scared him. In all the time they had known each other, Spike had never not been
able to see all of Xander’s thoughts in his eyes. What have I done?
Spike opened his mouth to say something (say what, he didn’t know), but the effort
was interrupted when Xander’s hand came down onto his cheek in a hard, sharp
slap.
Instinctually, Spike brought his hand up to his face, even though the sting was
minor and gone almost instantly.
Xander’s face remained blank as he said, “You broke your promise.”
If Spike’s heart had been beating, it would have stopped. The situation was what he
had feared. Xander knew. His vampire-instincts allowed him to play it cool, not
reveal his hand.
“Don’t know what you’re talking about, luv.”
“Oh, ok. We’re playing that game.”
“Honestly, Xander, no game. I really don’t-”
Xander leaned forward quickly, cutting Spike off as he brought their faces close
together. His voice came out in a harsh whisper.
“Did you think I wouldn’t know? Did you think I couldn’t taste it?”
