There was a shake to him, when he kissed her. He had to do it; her voice had been so intimate and private, and she was singing about touch and lips and sweetness, and the way her body moved against his as they danced, and the soft vibration in her throat as she slipped into humming– he had to. Every reason not to that he'd been thinking about earlier became background noise the moment he pressed his mouth against hers, tightening his arm around her back to pull her closer.
He didn't want to drag her into this Lust mess, he didn't want either of them to feel like he was using her, he didn't want to treat her wrong in any way, but god... he didn't want to stop kissing her either, and that want, as his tongue slipped into her mouth, was so much stronger than anything else it was like a screaming in his head.
