Sean forces himself to look back at that, eyes wide and mouth gone slack as he watches her come apart with something like awe, savouring every frantic movement and touch, swept along in it almost as fully as if he was the one getting his rocks off instead of her. He's never been one for power trips, but the rush he gets out of this, his stomach working itself into knots just trying to deal with it, it's something else, something special. Every damn time. Resting his cheek against her leg and flexing his jaw, he doesn't ease out of her until she starts coming down off that peak, the barest hint of a smirk turning up the edges of his mouth as he licks his lips.
