"You know," Remus said suddenly, "I think it is a lie what they said about your star."

From behind him, Sirius laughed, his breaths like whispering ghosts against Remus' neck, his voice low and teasing as he whispered a lazy "What?" into Remus' ear.

The werewolf shivered as a thrill of pleasure ran down his spine, but managed to keep his voice deceptively even as he pointed out the Dogstar to Sirius.

"Look at that. It isn't even shining that brightly. It is impossible that the Dogstar should be brighter than the sun."

"Ten times brighter, my Moony," came the immediate reply.

"Well, that can't be true. Because clearly even the moon is brighter than the Dogstar."

Silence followed that declaration, broken only by a stifled gasp as cold fingers found their way up Remus' shirt, careless movements in time to murmuring kisses trailed along his neck.

"Are you suggesting that the moon is brighter than the Dogstar now, my love?"

On a better day, or if he had not wanted those kisses – with the hint of a tongue as Sirius moved down his neck to his collarbone and then to the small hollow under his throat – to continue, Remus might have heeded the warning in his lover's tone.

"Brighter, and prettier too," was all he could manage, arching back into Sirius' touch as his eyes drifted shut.

"That is scientifically impossible, Moony. There is nothing more beautiful," a kiss as fingers undid the buttons on his cloak, "more charming," another button undone as hands and lips traveled lower, "or more … persuasive than the Dogstar."

And then there was no time for words, no reason to contemplate the Dogstar or the moon when they were already inseparable, inked together by the night sky, orbiting solely in each other's realities.
