There was a conversation to be had. Hannibal was, as always, deeply curious about the workings of his friend's mind, particularly considering the action Will took came as such a complete surprise. Will's ability to surprise Hannibal, even after all this time, was one of the things that kept him perpetually interesting to the older man.
However, it was a conversation for another time. Perhaps in the room that their hosts, whoever they are, were so kind to reserve for them both.
Hannibal smiled at the kiss as Will pulled back. "Not a terrible idea at all," he agreed. But if they were taking the physical contact they wanted, there was something he wanted to do first. He smiled at his friend, the man he had longed for, hungered for, was so proud of. He caressed his cheek gently, then leaned in and pressed his lips to his.
