It takes Obi-Wan mere seconds to understand what Klaus is looking for and he lifts his head even before Klaus is done speaking. His tongue comes out, dragging across the ring of muscle, his nose pressed against the underside of Klaus's balls, and Obi-Wan breathes deep, another shiver going through his body.

He wishes he could touch Klaus. Grasp him by the hips, pull him down against his face, but Klaus still has him pinned and so Obi-Wan merely flexes his hands and then relaxes them again as he uses his tongue and his lips as best he can. Klaus's skin is still hot beneath his mouth and he moans breathlessly, lapping at Klaus's hole, pressing his tongue inside for a moment and then focusing on that first ring of muscle again, paying as much attention to him as he can stand.

He pulls back to take a breath, but it's only a moment before he turns, face pressed against Klaus, his tongue fucking into him with enjoyment.
