The sight is undeniably arousing, but Obi-Wan is still a Jedi, and is more than capable of pulling himself back from his arousal so that he might do this properly. Under no circumstances is he willing to hurt Klaus, no matter how badly he might want him.

"And you'll have it," he promises as he reaches for their lubricant. He spreads a generous amount onto his fingers, then nudges Klaus's fingers, replacing them with his own. Klaus's fingers may also be slick, but Obi-Wan is taking no chances at all.

He's careful, easing one finger inside of Klaus's body, the tight muscle almost pulling him in as he goes. It feels different from how Klaus usually does, which somehow both is and isn't a surprise at all.
