That departure would have been Tony's cue to stop, but he was far too distracted now, grinning lazily at Bruce, too close to see, and fingers dancing restlessly along his collar and the back of his skull. "I can live with that," he said, because 'sometimes' didn't mean 'all of the time', and there was a lot Bruce could have done to put an end to this long ago. Unless that woman was still around, in which case...Tony had finally sat back, hands still tangled possessively in Bruce's shirt until Tony felt sure there was no good reason for him to keep his hold, then dropped his arms reluctantly, still scanning the room so he didn't have to look back right away.
