Derek growled, frowning and scowling at the mirror… for the fifth time that morning and Stiles had been trying to sleep, rolled around and wrapped up into a cocoon of blankets that he claimed for his own once Derek left the bed. If he had just gotten up to pee… he would have been shit out of blankets when he came back to bed. But instead… he had been having a growly argument with himself in the mirror. And he left the stupid en-suite bathroom door open. So Stiles could hear the whole thing.
With a sigh, Stiles uncoiled himself from the blankets and crawled out of bed, sleepily making his way to the bathroom. He leaned against the door frame, eyes still closed from sleep and his head barely upright, only staying on his shoulders thanks to his neck.
Derek mumbled something under his breath and Stiles somehow knew his boyfriend was refusing to look at Stiles’ reflection in the mirror.
“I don’t have werewolf hearing, Derek. You need to speak up.”
“…” The silence was followed by the gentle thud of Derek’s forehead hitting the mirror. “My eyebrows are too thick…”
Stiles peeked an eye open, one of his own eyebrows raised in question, “Huh?”
“Cora keeps telling me my bushy caveman eyebrows make me unapproachable and she’s right,” Derek grumbled and Stiles could tell how much it pained Derek to admit this… and Stiles tried very, very hard not to laugh at him because of how adorable he was. Standing there, slight blush on his cheeks, forehead pressed into the mirror, frowny pout on his lips… too cute.
Stiles pushed himself off the door frame, lips pressed together to keep from grinning like an idiot or giggling, and he stepped forward, wrapping his arms around Derek’s shoulders and pulling him away from the mirror. “It’s okay!” He rubbed his face against Derek’s cheek for emphasis, “I love your eyebrows!”
Derek inhaled deeply, shoulders relaxing from Stiles’ proximity and scenting. “Really?”
“Yeah!” Stiles kissed him on the cheek, nuzzling him more, “You’re my burly caveman wolf and I love you.”
Derek’s face deadpanned as he leaned back and let the side of his head hit the mirror again. Stiles followed, giggling against Derek’s neck and keeping his arms wrapped around his grumpy boyfriend.
