He's not planning on a full blow-job here - he's too aroused to have the patience for that - just a taste of what Spike might expect next time around. He may not have the vampiric advantage of not needing to breathe, but he knows what he's doing and has a few unique trademarks he's developed over the years. A bit of tongue-work, a hint of teeth, and because it's a dream he even manages to get Spike's jeans and boots off at the same, which is nice because he doesn't want to have to break in what he's doing any more than Spike will want him to. Only once Spike's lying entirely nude beneath him does he lift up, smirking, and licking his lips. "You taste fantastic," he says approvingly, crawling back up Spike's body to share that taste with him.
((OOC: No worries, as long as you tell me either way (if it's important - it's not always)!))
