"You're wearing far too many clothes, Harry," Draco mewled and purred, unaware of Harry's terrible allergy to cats. He unwrapped the woolen muffler, peeled off the balaclava, divested Harry of the down vest, the sweater-like jumper, the ski bibs, and the mukluks, until Harry was left clad in nothing but a pair of Snitch-decorated green silk boxers.
Right there. Before that I was able to hold off by turning away, but after that, my comforter stayed clenched in my teeth for the rest. MUKLUKS.
