K.
Yes, he might be a little too horny but he's definitely not a pervert.
His whole body stiffened, including his groin - a reaction that he totally did not expect. He had seen plenty of naked women, on the internet, in magazines, in real life - none of them made him feel what he was now feeling. K wasn't even completely naked yet. And though he could see her complete shape and form underneath the remaining clothes that was left of her, seeing her that bare somehow felt... different. He started to feel that it was actually him that was vulnerable.
