The second she felt the faint sting of his fang breaking the skin on her lower lip, Rose realized she should have also said no biting. She cursed herself silently for being a fool even as he released her and she cursed him aloud, in Russian, for being an asshole. It didn't hurt - or at least, the faint throb of the scrape and the blood that welled on her lip were nothing compared to the pain she'd felt in the course of doing her job, but she was angry that she'd given him even that little bit more than she wanted.
"You have what you wanted and more," she said, brown eyes flashing with anger as she swiped at her lip with one finger, glancing down for a brief second to check the level of bleeding. It would heal in a few moments. "Three weeks, and if I see you a day before that time is up, you'll come to rue this day." A weak threat, but threatening direct harm would be a lie.
