Even before he turns over and brings his knees up under his body, Obi-Wan is trembling. It's partly arousal, partly the exertion of hanging onto his tenuous control, and partly the intensity of the emotion he feels for Klaus, every moment when they're together. Klaus calls them filthy and perhaps they are by some standards, but all Obi-Wan feels when they're together like this is love. Physical attraction, yes, of course, but what makes it so much better, so much stronger is the love associated with every act.

He's always known how much better sex is when it's with someone who loves you, but he'd thought he would never again have such a chance as he does now with Klaus.

Klaus's thumb presses into him and he says stars and Obi-Wan drops to his forearms, his head hanging between his shoulders as he grins down at the mattress below him. Stars. Just like someone from home might have said and it makes his entire body tremble again even as he smiles.

Despite expecting Klaus's tongue next, the wet press of it still makes Obi-Wan's entire body surge, first forward, then rocking back against Klaus's mouth. And then, because he knows how much Klaus likes it, and he wants to give him the same feeling he'd just said when he had whispered stars, he moans, "Fuck, Klaus."
