accidentally falling asleep together, leading to a cute slow wake up like ~wow this is so comfortable, omg i’m so happy waking up in ur warm, strong arms and HOLY SHIT, WE FELL ASLEEP TOGETHER, and then avoiding one another because it felt SO GOOD but they can’t say that, and then every time they hang out, something wonderful happens, their fingers brush, they both laugh at the same joke, they catch one another’s gaze when something important goes down, all these lil things build up, they can’t avoid it, the things that used to piss them off about each other are suddenly endearing, they still bicker but it’s with such obvious heart eyes, it’s with good humour, kindness, they wake up thinking about each other, until one day Stiles shows up at Derek’s and bursts out with “i wanna sleep with you again” and Derek’s all huge eyed, soft sweater’d, in the middle of staring out of the window totally not thinking of Stiles and stands like UH, i– don’t put out that quick anymore shy BUT THEN Stiles is like “no no, i meant i want to go to sleep with you and wake up with you and do everything in-between with you, i just– i had a whole romantic speech planned but i got nervous and i don’t do this shit, okay? you don’t do this shit. it’s you! you’re Derek! you once threw up black goo on my sneakers and i still like you. i like you so much, it’s awful! but i wanted to tell you how i feel and instead i accidentally propositioned you, god this is so terrible an–” AND THEN DEREK KISSES HIM, ALL HARD BUT SWEET AND FULL OF INTENT.
and boom they together 5ever.
although in canon, now, i would want for the last montage of scenes to be someone calling stiles’ phone and a hand picks it up off the bedside table, we shoot to stiles brushing his teeth, derek peeks around the bathroom door, sleep ruffled hair and maybe one of stiles’ sweaters on, he smiles, hands stiles the phone and stiles maybe leans forward and gives him a toothpaste kiss, takes the phone and greets whoever it is, derek starts brushing his teeth, last shot is of the two of them doing their teeth together. domestic like.
