Touching Kaito seems to also be against the rules, judging by the way that without diverting his attention from the kiss at all, Kaito jams and then twists the handle of his whip into the muscle that spans between forefinger and thumb. And as if in constrast to that offhand abuse, Kaito shows, at least for now, that he can kiss normally. Teeth, but nothing sharp enough to draw blood, pressure that felt like possession, but not a threat. His tongue runs along the warm insides of Sora's mouth almost as if it was something he actually wanted to be here doing.
