[What a fun and sexy spreadsheet date it will be. Don't think he isn't spending most of the day here and sleeping over again anyway. His motives are pure (sort of) since he does want to make sure Spike doesn't freak out about all this since he imagines being alone in a strange body would bother anyone. And if they both get to enjoy this aspect of it as well, so much the better.
There are so many things he wants to try today but right now that response makes doing everything he can to get Spike off like this seem like the ultimate priority. And to be honest he's missed doing this to a woman more than he realized. The pleased hum he makes isn't entirely in response to all that toe curling. Part of it is based on his own enjoyment, too.]
