I really am growing fond of the cuteness that is Severus and Sirius. I hope you are too!
No matter how big Sirius was as Padfoot, he insisted on sitting on Severus' lap. No matter where they were: in public, at the park, in the floo or at the desk – Sirius insisted on balancing himself across his lovers knees with no regard for the male anatomy. This particular evening was no different and as Severus slumped into the hard wooden chair he used for grading summer tests, the familiar sound of overgrown claws on wooden floors made him roll his eyes. Instinctively he placed a hand across his crotch to shield himself from the imminent force that trotted closer.
"I've got a lot of rubbish to grade, Black. I refuse to entertain your – oomf."
He growled but accepted defeat, absent mindedly brushing his fingers through Sirius' thick fur. The dog cocked his head in response, beating his heavy tail against Severus' leg. He could smell tension emitting from his lover and the deep crease between his brows looked ready to swallow them both.
He licked Severus' knuckles, forgetting that the man hated the sticky residue he always left behind and nuzzled his nose into the crook of his arm. His paws were too long for Severus' thighs so he kneaded them awkwardly into the mans muscle while he tried to find a grip.
Severus groaned in protest, spreading his legs as he attempted to make room for the overgrown dog who seemed to be suffering from a delayed puppy hood. "You're not a pup anymore. You're overgrown and heavy and bloody well awkward," he snapped. Sirius whined in protest. "Hush your whining, Black. It doesn't work...anymore," he smiled gently, scratching behind Sirius' ears. "Five more minutes, okay? I really have a lot to do."
As always, five more minutes became ten more minutes which quickly became a lazy shuffle to the couch as they snuggled across its length. Sirius transformed to his usual self with his soft cheek brushing against Severus' stress induced stubble. They lay like that, oblivious to the world beyond the study door and forgetting the imminent war that lurked steadily closer. They had each other and in these moments, the war didn't matter.
