It's an entirely different experience than when Klaus is in his usual body, not better or worse, just different, and knowing it isn't going to last forever makes Obi-Wan all the more enthusiastic about making sure Klaus enjoys the experience. Every last moment of it.

He enjoys it, too, the way Klaus is grasping at his air, the way his thighs are pressing to his ears, making it so all the sounds in the room are muffled. It makes Obi-Wan feel as if they've found themselves in their own little world.

Within Klaus's body, he crooks his fingers, curling them, pressing into that place he knows must be inside of him. This is different, too, but he knows what he's doing, and he almost grins against Klaus's clit, licking and sucking, his fingers working a bit more enthusiastically now, too.
