Thinking that Chas liked it rough was a bit of an understatement. Though exactly how rough she liked it really depended on who she was with. She'd see how far it went with Alec, here... though she certainly wasn't complaining so far about his teeth, or the way his fingers were digging into her skin.
Which, she realized as she kissed him, she would like quite a bit more of. And that involved less clothing. She managed to push away from the wall just enough so that her hands, releasing his shirt, could shift to tug off her trench coat, letting the black leather pool to the floor and leaving her in the fitted black tee she wore beneath it. The action also revealed the Mark on her arm, though she wasn't sure if he'd noticed that, since her lips were still on his. She didn't really care.
What she did care about, though, was that his shirt was in her way. Her fingers found the hem, tugging at it, only breaking the kiss when she had to in order to pull it off.
