It's intoxicating to keep herself poised on the very edge of her extremely precarious control like this -- to take whatever he's throwing at her and not retaliate, not because she can't but because she chooses not to. Because she chooses to watch him take the reins. Because he's her husband, and she was always a good wife, loving and tender and submissive to his will.

"Could you, really?" she smiles, realising that she has no answer for his question and isn't ready to give him her silence just yet.
