At this point, it should not surprise him how moments of genuine emotion work their way into even their filthiest of encounters. He's probably teasing in this particular instance, but the knowledge that anyone would care about Klaus being proud of them in any way, especially someone as incredible as Obi-Wan, nearly undoes him.

He lets out a ragged moan just at the word, turning his head to press a kiss to Obi-Wan's cheek as he pulls his fingers free and retrieves the condom from his pocket before undoing his pants enough to pull his cock out. After quickly rolling the condom on and slicking himself with the last of the lube, Klaus drops both packets and reaches up to curl his clean hand around Obi-Wan's presented throat, holding on loosely as he bends his knees and positions his cock at Obi-Wan's hole, nudging the head in slowly and then driving his hips forward to sink in with one quick, smooth thrust.

"I am always proud of you," he gasps out against Obi-Wan's ear, wrapping his other arm around Obi-Wan's stomach to pull him back snug against Klaus's body, simply holding onto him for one long moment to let Obi-Wan adjust to him. His other hand stays curled loosely around Obi's throat, keeping his head tipped back against Klaus shoulder. "You are the best of everything, Obi."
