That smile settles something in Klaus, reminding why he decided to do this in the first place. He trusts Obi-Wan in a way that he has never trusted anyone before. He trusts this man with his body, and more importantly, his heart. He trusts him with his secrets and his fears, and he can trust him with this, too.

He takes another long look at the sky above just before Obi-Wan kisses him, and then his eyes slip closed as he returns it, licking into Obi-Wan's mouth and spreading his thighs to make room for him. For a moment, all of this feels like it's happening to someone else, because this is so unlike anything he's ever experienced. All the romance, all the warmth, being held and kissed on a rooftop bed on Valentine's Day, all of it. But this is his life. Somehow, he has become a person who gets to have these things.

Obi-Wan bites his lip and it makes the whole thing feel more real, more them, because Obi-Wan has taught him that they can have romance and love, but also bites and scratches and bruises in the shapes of their fingers. He's taught Klaus that they can define love for themselves, and build something all their own.

His finger presses in and Klaus lets out a soft, approving him, blinking a few times as Obi releases his lip from between his teeth. Klaus licks away the slight sting and reaches up to curl a hand around the back of Obi's neck, pulling him in for another deep kiss as Obi-Wan fingers him open, first one and then two, until Klaus is rocking back against his hand with a needy whine.

"Obi, please." He gasps and clenches around Obi-Wan's fingers, wriggling his hips a little as he squeezes the back of Obi's neck. "I'm ready."
