Who cooks:I was my very first Kisame's headcanon that Kisame knows a fair bit of cooking. At least, during travels, he can catch and roast a few fish for Itachi. But as the pair travels, it's food from restaurants.Who does the laundry and other chores:In a setting with a permanent home, Kisame would urge Itachi to rest and he would take care of the chores. What small bit of chores they might while traveling would be up to each person.How many children do they have:none!Who’s more dominant:Itachi. But it is not about power and intimidation. He is simply someone Kisame respects greatly, and Kisame will listen to him without question. Itachi knows what orders to give and in intimacy, would call the shots.Favorite nonsexual activity:The cutest thing I can think of while traveling is Kisame floating on the water's surface with Itachi laying ontop of him. Kisame can easily bear his weight, and not worry about drowning.Their favorite place to be together:Generally as long as they're around each other.Any traditions:As far as traveling goes, their tradition would become their nightly ritual, preparing for bed and making sure they won't be located and attacked.Their “song”:lolWhat they do for each other on holidays:Nothing they don't normally do each day.Where did they go for their honeymoon:They won't get married so there will no honeymoon uwuWhere did they first meet:Kishi fricked with timelines and based on his appearance in canon it looks like Itachi was in Akatsuki for a few years before being introduced to Kisame. But I like to believe they were immediately paired up with each other.Any pets:Does Kisame...count...as the pet.....What do they fight over:Itachi isn’t argumentative, and Kisame won't disobey him. Kisame does mother hen him though, telling him to rest, and to not overuse his Sharingan.Do they go on vacations, if so whereEvery day is a vacation
