Hermione smiled, shifting her fingers to his belt and removing it before unbuttoning his trousers. His hips, also pale, were slim and his legs were well-defined as she slipped the trousers to the floor.  Helpfully, he stepped out of them easily and then he was only in his pants. Since he had just come - twice - she hardly expected him to be hard, but it was with a jolt that she realised she’d only ever seen men undress when already aroused. If you disregard the time she was on the run with the boys of course, but that was over a decade ago and they were more brothers than men to her mind. Regardless, she’d had no interest in looking, but she certainly  did  have an interest to see Snape naked. Hooking her thumbs into the waistband of his pants, she glanced once more at his face to check that it was okay. His expression was neutral, and if anything he seemed vaguely amused. Finding that somehow encouraging, she pulled his pants down and waited for him to step out of them before standing and looking at him.
