Ron's left hand was nearly numb from the ice cream cone he was holding, but he didn't care. He watched Harry as he slowly swirled his tongue around in the quickly melting chocolate. A drop fell onto his hand and ran down his slender wrist. Keeping his eyes on Harry, he raised his hand to his mouth.
Harry watched hungrily as Ron slowly, slowly, oh God! Ever so slowly licked the ice cream off his hand. Harry looked back into Ron's eyes, silently pleading with him.
Ron grinned slyly. "What's the matter, Harry? D'you want some?" He slowly flicked his tongue out of his mouth and ran it along his upper lip. He could taste the sticky sweet chocolate that was stuck there. He scraped some off with his finger and sucked off the chocolate. Harry whimpered softly and barely managed to nod. "Well, I guess we'll have to share, then. Oh... oops!" Ron looked down in mock horror as he dropped the ice cream cone. "Well, there goes that. But there are other ways to share..."
Harry couldn't take it any longer. Before Ron could say another word, he pounced on Ron and firmly kissed Ron's sweet, chocolate-stained mouth.
