Most Alluring, Dear Moony

1.
"You are exquisite," said Sirius Black. He was hanging over the back of his chair, grinning luridly at Remus instead of paying attention to Professor McGonagall, who was glaring quite stonily at the back of his head.

Remus flicked his quill at his friend's forehead, smirking at the splattered black ink that smudged over Sirius's eyebrow. "Face the front, Black, or face detention."

"Oh, so strict, Mr Moony," Sirius smirked, but he turned back around and paid their miffed professor his undivided attention for the rest of the lesson while Remus stared thoughtfully at his friend.

Sirius fought the swell of students streaming into the Great Hall to position himself by Remus's side.

"Merlin, what now?" Remus sighed in defeat, anticipating another humiliating declaration. He scratched the side of his freckled nose, hovering in place while Sirius gathered his showmanship and tried to get within earshot.

Sirius beamed when he found his place at Moony's side and clutched his arm. "Aw, you've gotten used to it. Am I growing on you?"

"You can only hope," Remus muttered.

Sirius frowned. "I should be by now. I thought you'd enjoy proof I'm becoming well read."

"Nicking a thesaurus from Madame Pince does not a well read Padfoot make," Remus said wisely. He tripped in the next second, and Sirius could just tell that his friend was envying his own shorter height. It must be awful, having legs like stilts, to be so gangly.  Actually, his mind suggested, Remus is quite well proportioned. He's tall but he's filled out a bit, hasn't he, not skin 'n bones anymore. In fact his shoulders are broad, and he's stronger than he used to be which you know because of that time Snivellus tripped you and he caught you in his arms in the snow, and his cheeks were pink, and he smiled and his lips are probably chapped and rough but it would feel nice anyway and—

Not for the first time, Sirius cursed Remus for turning him into such a lovesick prat. Only for a little, because he was right back thinking about Remus's summer growth spurt, and his mouth dried.

It had made him the perfect height, though, for hugging, and resting his chin on Sirius's head which always made him feel warm and safe and protected and loved and wanted, and—

"Moony!" Sirius yelped. Remus gave him a questioning look and pushed his curls off his forehead. Sirius envisioned carding his fingers through Remus's hair, twisting it, kissing him firm on the—

"What?"

"Why, you're sublime, simply sublime," chirped Sirius, before his mouth could run in lieu of his brain and have him blurt out some terribly incriminating stuff. And then, like a hero of old pulled from his Remus by forces of evil, Sirius was tugged away by the tide of witches and wizards running towards food in empty stomachs.

Sirius looked both ways, checked under the table for good measure. He tapped the Advanced Arithmancy book that he was nearly positive had never seen the light of day and waited for James to signal that Moony was on his way.

James, peeking through a gap between two Divination tomes on a mahogany bookshelf, gave a complicated hand wiggle that took the two of them weeks to perfect. Remus incoming.

Sirius rearranged the placing of the two open books and readied the charm. Remus stepped around the corner towards his favorite window table that Sirius has already commandeered, smothering a yawn behind his left hand, the one with the silvery scar shaped like a wave on it.
