"You're mine!" Stiles growled, the sound nowhere near as impressive as he had anticipated, nowehere near the growls that Derek and the others could produce, "You're mine, Derek." He repeated, wrapping himself around the warm body next to him.
Derek chuckled, the sound still somewhat unfamiliar to Stiles, so low and yet so warm at the same time. Stiles loved that sound - one of many sounds Derek made for his ears only. Now, though, it just irritated him.
He expressed this by giving Derek a sharp kick to the shins, "It's not funny." He grumbled, mouthing at Derek's shoulder briefly before pulling his head back up to glare at him, "I'm yours." He said, and watched with pleasure as Derek's eyes flashed red before fading back to their , "I'm yours and that makes you mine, alright." He tightened his grip around the werewolf, and bowed his head to brush his nose along Derek's neck. It was an action he'd picked up from his ... boyfriend? Where they calling themselves that yet? Whatever. It was something Derek did, something to do with his scent, and something that Stiles had no real reason to do, besides the fact that it made Derek stiffen in his arms and whine, leaning his neck to the side to give Stiles better access. He pressed a teasing kiss to Derek's throat and withdrew again to look at him.
"I don't like it when girls flirt with you." He told him, trying and failing not to flush when Derek's smile grew warm.
"Possessive little bastard, aren't you?" Derek teased, then gasped as Stiles sunk his teeth into his shoulder, tongue laving at the mark they left behind, "What the hell?" He choked out, though really, he so wasn't complaining.
"Consider yourself marked."
"Wh-" Derek gaped, eyeing first the mark, and then Stiles. Finally he closed his eyes and sank back into his pillow, taking Stiles with him, "I need to take away your internet connection."
