Klaus' gasp after Bill's hand smacked against him dissolved into laughter and a pleased groan when Bill promised that he could show him something. Klaus had encountered many who would have wilted under the taunting - allowing Klaus to bully his way to the top even when he was the one being fucked. But Bill gave as good as he got and Klaus loved it.
He groaned when Bill instead of snapping his hips forward in another sharp thrusts just continued to stroke him, pulling Klaus along at this different pace. The sensation of it tingling at the base of his spine as his hips arched pressing for more even as Bill continued to deny him what he most wanted.
"You're going to have to do better than that," Klaus said with a smirk on his face, his tone with more confidence than he probably should have, but that was who he was, always throwing himself into the deep end and hoping to keep his head above water.
