Noah's not even thinking about breathing. Although he often gives the appearance of doing so, it's only out of habit. One of those unconscious processes that's hard to shake long after its purpose has become immaterial. Actually getting air is no longer a concern.

All he cares about doing is sticking his tongue out as far as he can so Jamie can fuck himself on it. That's all that seems to matter in the space his world has narrowed to.

Though there is half a second where his fingers tense on Jamie's thighs. It's just dirty talk, he knows, he knows that... But he can't control the twinge of apprehension it brings up. The memory of his heart in Jamie's hand. His eyes flutter open and closed again. This is different... He's here because he wants to be.
