Klaus grinned as Bill cheered with the crowd as the music shifted, something with a better beat, he could feel it in his chest, just like he felt the shift of Bill's hand down over his hip and to his ass. Klaus knew how to move with that kind of touch, to press close, leaning his chest into Bill, but shifting his hips enough that he made no secret that he enjoyed Bill's hand on him.
Letting fingers glide over Bill's shoulders and along the back of his neck, where his hair was drawn up and away from him, no doubt to help keep him cool in a place like this. "What's a man without his honor?" Klaus replied with a light sort of shrug of his shoulders, the hand on Bill's hip pushing its way up, fingertips shoving their way beneath his jacket to get under his shirt and skim over bare skin just a bit.
There had never been any part of Klaus that hesitated over the things he wanted, not even when he'd been young. Thoughts of what it might do to a friendship or repercussions never entered his mind, things simply happened and he dealt with whatever followed - or didn't in some cases. He let his lips brush against Bill's neck, and then higher along his jaw, before he lifted his head, watching Bill's face for just a moment as they moved with one another, the press of music and people all around them, and all Klaus wanted was the heat of Bill's mouth and so he pressed forward again, kissed him with all of that want and desire and continued moving with him.
