He could choose to be offended that Spike apparently can't face kissing him without a good dose of alcohol before hand, but frankly, he's getting what he wanted so who's he to worry about what it takes to get there? He's grinning as Spike's mouth crashes down onto his and his hands are halfway in the air before Spike even gets there, pausing for a moment before wrapping around him, one round his head, one round his back. He more than meets the kiss, pushing up into it as Spike pushes down, so that there's more than one clash of teeth in amongst the press of lips and the tongue that rapidly gets involved as well.
Well, neither of them do things by halves, and they've been working up to this for a long time.
He moans breathlessly, pulling Spike close, unable to get enough of him now that they're finally there.
