Remus groans and smiles and pulls Severus' hair. He loves it, loves it like this, loves it hard and frantic and desperate.

He arches against the wall and tightens his legs a little, tilting his hips with Severus' movement.

"Fuck, yeah!" God, he's so happy, he doesn't know which feels better, the joy at being here with Severus, or the actual physical sensation. "Hard, do it hard, I want to feel it long after we're done," he mumbles, kissing Snape's face, moaning sharply as the other man proves he's good at everything he does.
