Or maybe I'll leave you hanging for awhile...Sorry again but I think this is just the way I am.
Seeing your Godson half-naked rutting against the likewise shirtless Boy Who Lived and seemingly attempting to snog his face off was not a thing that Snape ever wished to see. He wished he could manually scrub this from his mind and possibly his eyeballs as well for good measure. After a few long moments of being completely gob smacked, Severus was brought back to the present by Padfoot's snort of what seemed to be approval.
With two long strides he was in the clearing and towering over the oblivious young wizards.
"Ahem…" The gruff sound had the boys springing apart in an instant with gasping breath, heaving chests, and wide eyes. A tense moment followed in which Snape glared menacingly between the two on the ground while Harry looked horrified and embarrassed. Draco simply shrugged his shoulders and looked smug.
"What in Merlin's name is going on here Draco?"
"Oh Severus, I always got the impression that you of all people would know exactly what two men do…"
"Enough. Ten points from Gryffindor for entering the Forbidden Forest."
Potter was almost able to overcome his blush to object to Severus' predictable penalty and returned the glare. That is, until he spotted the panting black dog at the potion master's feet.
"Padfoot?"
The animagus yipped in response and launched himself at the boy. Draco scooted away from the unknown animal with a disgruntled grumble as Harry embraced him and began to pet him enthusiastically.
"What are you doing here? I thought you had to stay at Grim… at home." Padfoot just nuzzled the boy and licked his face.
"The mutt escaped and now refuses to return to his home. Would you happen to know why the idiot won't leave me alone?"
Severus returned his glare to Potter while Draco looked between them in confusion.
"Whose dog is this exactly? I didn't know you had one Harry."
Potter looked up at Severus as if to ask for permission.
"Absolutely not Potter."
"But we're dating."
"As disturbingly true as that may be, you are not telling him."
"He's my Godfather, Sirius Black." Draco looked down at the dog in alarm. Severus glared with fervor and exasperation at the blatant disregard of his authority.
"You are an imbecile. Are you unaware of his father's position…"
"You mean right next to you at snake face's feet."
"Potter…"
"I won't tell anyone Severus but…um isn't he a crazed murderer. Should he really be out and about?"
"That's why he's kept on a leash. Now Potter, I do believe that you can take him from here."
Severus turned intending to relinquish responsibility for Black and return to his routine. Unfortunately, the dog was growling in front of him before he could take two steps.
"I think Padfoot wants to stay with you Professor." Potter's amusement was doing nothing for Severus' headache. He snatched up the leash and motioned for the boys to follow him. They rose and righted each others' clothes. Severus was nauseated to see Draco smooth down Potter's collar with a small smile.
"Do you really think that your father won't hear about you running around with the Gryffindor Golden Boy, Draco? That could be messy. How exactly did this come about? The two of you have always despised each other."
Severus really couldn't fathom how they could just forget all of the fistfights, duels, and insults that they had exchanged every chance they got from their first meeting. He had been intimately and reluctantly familiar with the state of their relationship due to Draco's whining during his private potions lessons. This turn around though, was unexpected.
"I don't give a damn what my father thinks, Severus. Anyway, we just changed…or no, we didn't change; we just realized that all the energy we spend on each other could be used in more productive ways."
With that, Draco leered at Harry and gave him a wink. Of course, this spurred the blush to return to Harry's face.
"Enough. I don't want to hear about it. What I want is for the mutt to stay with you Potter."
By then, they had returned to the sunlit hill looking down onto the Black Lake. Potter took the leash and walked with Padfoot out of earshot. He knelt down and had what appeared to be a very deep discussion with his dogfather. Just as Severus was losing patience, the boy nodded and strode back to them.
"Professor Snape, Sirius is staying with you. I think he has unfinished business with you and anyway, students aren't allowed to have dogs in the dorms. You two have fun! Come on, Draco."
Before Severus could object, Potter had dropped the leash, grabbed Draco's hand, and ran down the hill.
"That boy is just as reckless as you Black." The dog yipped and licked his hand.
"That was not a compliment. Come along then; I have work to do. I know such a concept is foreign to you."
Severus grabbed up the leash and tugged the compliant dog toward the castle. He had not intended to allow this travesty to continue but at the moment, he saw no way out of it.
