Susan, who has worn actual armor -- leather and mail, primarily -- likes very much the idea of her underwear also being armor. Or maybe she just likes Liu Mingyan's mouth at her tits. She also appreciates that Liu Mingyan isn't shy about being rough, and tugs harder at her hair. Her other hand she moves to cup Liu Mingyan's ass, feeling the shape of it through her thin trousers; from the (lack of) texture, she's pretty sure that Liu Mingyan isn't wearing any underwear, herself. She likes this discovery, too.
