Anna laughed, rocking back down against him as he rolled his hips. She stroked him a little more earnestly, working to get him in the position to want and be needy. "Whether you want it or not isn't the issue here. The issue is that I have you where I want you." Which, to be honest, probably personified their entire relationship. A continual back and forth of giving control to get it. She was fine with that for now.
She knew he was using her, and maybe whatever he was using her for was more sinister than what she was using him for, but she was definitely using him. A distraction at the most. And maybe to piss of Castiel and Dean a little, because she was pretty sure neither of them was happy about it.
"So tell me, is this what you want, Crowley? Is this exactly where you want to be?" Anna purred into his ear.
