There's about a thousand words that've been used over the years to describe what it is that Jim's doing to him, but none of them apply, as far as he's concerned. Jim's perfect and he's better than anyone he's ever had before (not hard when Jocelyn only did this every so often and his memories are steeped in bitterness). Still, he wants to remember this for the good, wants to experience it without the past clouding in, so he closes his eyes and stops thinking.

Which is about the time he really starts enjoying, face going slack with bliss.
