Harry threw himself at Snape, mashing their mouths together as suavely as he'd done the first time, that horrible night in Brazil. Embarrassed as he was, when he finally stepped back, he still managed to croak out, "Don't leave." To ensure he couldn't, Harry kept a firm grip on the front of Snape's robes.
"Potter..." Snape's lips stayed parted, as if waiting to speak more words that simply wouldn't come.
There, in the middle of the most luxurious bed Severus had ever seen, lay Harry Potter. The boy's eyes were closed, his coal eyelashes resting on his rosy cheeks. Severus had never seen the boy look so innocent, so relaxed, so lovely. He wanted to gather Harry in his arms and keep him in this beautiful place where nothing could harm them.
Sliding his wand back into its pocket, Severus retrieved the vial of hair-lengthening potion that Harry had requested. Taking it with a grateful look, Harry overbalanced, falling against Severus, who looped his free arm around the slender waist.
He lifted the hand from Severus's waist, and tangled it in Severus's hair. With a sly smile, he said, "Not to mention I love how often you wear your hair in a ponytail. And how you style it...." He lost himself for a moment, running his fingers through Severus's hair. When he caught himself, he shook his head and added, "I may sound completely mad, but even though you two have the exact same face, you somehow manage to look so different."
All that changed when Snape suddenly rose to his feet, reached out and brushed back the cowl from Harry's face. The hood of the cloak draped across Harry's shoulders, his long hair spilling out from underneath the cloth as Snape's hand graced Harry's cheek.
