Desmond was caught off-guard by the affectionate nuzzle to his cheek, and for a moment, all he could do was blink rapidly in surprise. "Michael?" he mumbled quietly, even as he leaned into the nuzzle. He was a sucker for affection, and he couldn't stop the faint smile that tugged at his lips. He was confused though; Michael was always pulling away from him when he tried to be affectionate like that. "Are you-" He trailed off, not wanting to offend the other man by implying that he was doing something out of character, in case he was just trying something new.
