As much as it might be biased to say at the current moment, Arthur did think Ariadne was beautiful. The fall of her hair over her shoulder, the upward glance of her eyes... He carded fingers that soft hair, enjoying the feel of it without trying to direct her. He didn't mind the slow tease, actually, it helped distract himself from the overload that was she on her knees and Eames behind him.

Still, Arthur's lips parted as the warmth of Eames mouth touched and then was gone, leaving him to turn his head following it. The bristle of short hair slipped out from beneath his fingers and he swallowed a moan, pulling a hand down his face.

This was not going to end well for him. "Eames--Ariadne--" Arthur actually reached finger to touch her, distract her, from Eames' request.
