It was late October and the evening air was crisp. Severus almost wished he'd taken a heavier cloak. The rustle of leaves muted the night sounds as they skittered across the earth. A howl went up and then another; Severus hoped that the noise meant 'good-bye' in werewolf. A few minutes later, he heard the crunching of leaves as Remus bounded toward him. The damp muzzle pressed into Severus' hand.
"That had better not be blood." He admonished. "Are you done playing with your friends?" He didn't wait for an answer, because except for a nod he wasn't going to get one. "I am chilled; it's time for me to have a cup of hot chocolate." Remus woofed, happily. "No, none for you. Chocolate is toxic to canines."
Severus saw the hind leg lift and he pulled his cloak tighter with one hand and sunk the other into the soft ruff. Severus could feel his face flushing, warm and rosy. "None of that, you may save your kinkier pursuits for our bedroom or bathroom when we are both more or less approximately human."
Remus whinged.
Severus released his fingers from Remus' fur. "All right then, if you must use a tree. My first attempt at bestiality will not be out of doors in the cold."
Remus stopped mid-piss, leg still raised, his eyes boring directly into Severus'.
"Oh, finish up. You heard what I said. Yes, I said the first time as there will doubtless be more."
Remus continued and Severus resumed his monologue. "I know we have never spoken of it, and you are surprisingly easier to tell this way. I imagine it is because I am not getting an argument or I do not have to watch a thousand different thoughts flicker over your face." Severus' back hit the ground a split second later.
Remus licked Severus' face in long wet strokes. Severus fought to push Remus off. "Slobbering on me is not considered watersports, wolf." He chuckled softly and grabbed Remus' ears. "Enough. I am cold and now wet." Remus took one more lick and loped off.
Severus righted himself and his clothing and Remus came back to him. The wolf walked slightly ahead with a fair imitation of arse wiggling. "That will not make up for the slavering, you know." Remus wiggle exaggerated. "Promises, promises, Lupin. When was the last time I had that lovely arse of yours?"
Remus yipped and then growled.
"Oh, don't be so touchy. I know it was just this past Tuesday." A cool wet nose bumped Severus' hand. He stroked the silky fur on Remus' head. "Come on, now. We have dallied long enough."
