Doing chores together.
Some of these chores doesn't need two people, but come on, it's always fun when you're together.
Doing laundry together, that just escalates to a full on bubble war and just running around chasing each other with bubble foams.
Folding laundry, but both just end up cuddling on top or beneath the mountains of warm clothes. One of the other totally not burying/throwing the other on top
Sweeping the floor, there is a reason why you have two brooms, for sweeping medieval sword fights.
Watering the plants outside, yup, this just ends up in a war of hosing the other down.
Making the bed/changing the sheets, you know those fitted sheets? Mhm imagine one of your top characters just making the bed and somehow the other just manages to wrap them in a fitted burrito and just wastes the day cuddling to the wrapped burrito.
Grocery shopping, instead of actually getting groceries imagine your otp racing down the aisles the other inside the cart holding onto dear life while the other pushes the cart rivaling the speed of sonic. Or playing hide and seek until they had to be kicked out, almost banned even.
Restocking the pantry with both just ending up being surrounded by bags of food and both are on the floor eating and chatting away.
Repainting the room, with the room ending up with crazy abstract design due to both flinging paint at each other and just smearing paint at one another.
Washing the car, the other already started washing the car, then their s/o comes out with a speaker and their shirt bunched showing their stomach, like those car wash sexy videos, and then there s/o proceeds to try to wash the car seductively and playful, but end up just getting soap in both their mouth and eyes while the other just either watches amused or full on laughing
