Terror made Magnus' chest seize up in the moment that Alec pulled away, fear that he would run away and pretend like this never happened. But all he did was rest his forehead against Magnus', a gesture the demon was familiar with but not so personally, so genuinely intimately, and try to catch his breath.

Magnus did, too, but he keened softly once Alec was kissing him again. His hands started to move now, running through Alec's hair, moving down his shoulders. Not down his chest, there wasn't enough room between them to manage that.

He broke the kiss periodically, just for a pant of breath, and to murmur against Alec's mouth. "You're amazing."
