Sadly, Hermione didn't always have to act for this. He studied her passionately, like she was an exam he was quite determined to pass, and had unfortunately done well in the process. Distancing herself from the assault was never easy—her mind was too full of hate, too aware of her surroundings and him, to be exact. On better days he left her alone while she was in the palace of her mind and made no move to disturb her there, but had no qualm over disturbing her body. On worse days he took her anyway and made damn sure she felt everything he did to her, and that she finished before he did, and because he was greedy, he made sure she came repeatedly. Not because he was a considerate bed partner, but because he knew she did not want it, at least not from him, and he enjoyed taking it from her. It was another way of reminding her just who she belonged to.
