Moaning into the kiss when Magnus moved closer, he knew that he was in trouble. Magnus could do anything he wanted and Alec would agree. Not because Magnus was a demon. If it was that simple, Alec would fight his feelings and gain some measure of self control. He knew when Magnus was using his demon charm on him.

This was simple. This was kiss shared without compulsion or the hunger that Alec was afraid would destroy him. This was what he'd been wanting while he avoided all those blind dates and hook ups that his siblings had set up for him.

Eventually he pulled away, needing to catch his breath, resting his forehead against Magnus' for a moment. Then Alec kissed Magnus again, trusting Magnus not to harm him
as he lost himself in the feeling of the two of them wrapped around each other.
