It was nice, an absolute treat for the ego to be on the receiving end of Klaus' praise and attention. In the Wizarding world Bill was recognizable, people knew his family and that wasn't always what he wanted. So Bill enjoyed getting out in the Muggle world instead, where he was just him, not a pureblood, a blood traitor, a Weasley but just Bill. Like he was here, a wizard in his own right, just a man that wasn't about to disappoint.
Heat had settled low in his stomach and Bill wrapped his fingers around the pale column of his throat, holding him in place as he leaned in to kiss him again. It wasn't threatening or tight, Bill was gentle but possessive as he held the other man in place. "Careful, love," he murmured as the kiss broke. "I might go getting ideas."
Even if he wasn't actively dancing anymore he still moved with the music, hips swaying like the beat was moving through them both.
