Steve and Tony just chilling on the couch together. They aren’t even particularly close together, each one on the opposite side. Clint and Thor are yelling at each other about who’s cheating at Mario Cart. Natasha and Bruce are in the kitchen, listening to music and cooking dinner.
Steve is sitting on one side, reading the news paper, occasionally glancing up to watch Clint and Thor play. Tony is on the other side, playing with his tablet and egging Clint and Thor on. The ground shakes as Thor jumps up and down, accusing Clint of cheating as he loses again. Natasha yells at them to calm down or get out. They both sit back down, grumbling to themselves. Bruce can be heard laughing from the kitchen.
Amidst all the noise and chaos and craziness, Steve and Tony continue to just relax on the sofa. And then occasionally they’ll glance over at each other at the same time. They’ll look at each other with soft eyes and small grins. Steve will wink at Tony and Tony will smile wider, stretching his body out further and pressing his feet into Steve’s thigh. Steve will turn back to his paper, but he’ll mindlessly put his hand on Tony’s leg and run his hand up and down his calf. Tony will go back to his tablet, but he’ll keep trying to stick his toes further under Steve’s thighs every once and awhile.
And even though the common area is loud and chaotic, they’re content to just sit there amongst the noise and enjoy the company of their family and the one that they love.
