Who’s more dominant: Wade is but if he steps out of line, Peter has no problem using his super strength or super sass to put him in his place.
Who’s the cuddler: Wade. He clings. He’ll actually fling himself off roofs and force Peter to catch him, so he can cling. He’ll also convince Peter into giving him piggybacks whether while walking or swinging on webs.
Who’s the big spoon/little spoon: they usually don’t cuddle while they sleep. Peter will either curl up on one side of the bed while Wade sprawls everywhere. Or they’ll both sprawl everywhere and Wade will end up on the floor… or the ceiling if Wade gets fresh in their sleep.
What’s their favorite non-sexual activity: video games. they shout loudly, push each other and sometimes wade ends up webbed to things and somehow can still use the controls
Who cooks: Wade cooks breakfast (pancakes, lots of pancakes), Peter makes them sandwiches for lunch, and either Wade will bring them takeout or they’ll got to Aunt May’s for supper.
Who comes home drunk at 3am: Wade. Drunk. Bloody. Not always in one piece.
Who kills the spiders: Wade tries to. He goes through about two cans of Raid a week and all Peter does is cough, throw the can out the window, and punch him in the face.
Who falls asleep first: Peter. After a long day of college and being Spider-man and dating Wade Wilson he gets very exhausted.
A head canon: Aunt May and Wade get along ridiculously well and Peter hates it. They swap recipes, he tells funny stories about Peter talking in his sleep about math and nerd stuff, and May tells Wade stories from when Peter was a kid. Wade acts like a gentleman and a civilized person around Aunt May and Peter loves it.
