Everything will change, Remus knows, upon their return to Hogwarts.
Sirius has already begun to pull away, and although Remus expects it -- has since the very beginning, really -- he is still unaccountably hurt by it. A summer fling, he reminds himself, when Sirius stretches and his shirt rides up, and forces himself to remain distant when his fingers ache with the suppressed need to touch.
Then Sirius smiles, wicked and bright, and Remus forgets about safeguards and inevitable endings, and instead concentrates on capturing this moment in his mind.
Tomorrow is an intangibility, but summer exists eternal in Sirius's
smile.
