Jon purring but during cockwarming. It’s a strange little sign of his inhumanity that neither of them really expected. He’s on his knees for Elias, or maybe in his lap, Elias half-hard inside of him. And Jon is just so warm and content and sleepy. Nice and relaxed. Just there to be Elias’ good boy, his precious pet. Letting out a low, gentle purr that he doesn’t even really notice.
