Similar thoughts (Oh Merlin, I'm kissing Fred!) were running through Katie's mind, though the mental commentary sort of fuzzed out for a bit when his fingers curled into her hair, and he pulled her just a bit closer. Her lips parted against his in return as her hands tightened for a moment against his waist. Merlin, this was incredible.
When he pulled away and broke the kiss, she took a deep breath, but smiled as his forehead rested against hers. "I don't know," she replied with a light laugh, "That sounds an awful lot like forfeiting! Fred Weasley, admitting defeat, all over some mild feminine wiles? Because really, I was barely trying! If you're talking wiles, that was nothing."
