The avengers are playing truth or dare
Steve: Nat, truth or dare?
Natasha: Dare, Capy
Steve: I dare you to kiss the next person who walks in
Natasha: I'm not kissing anyone!
Clint: Oh, come on!
*Five minutes later*
Natasha: Steve, can you get me another beer please?
Steve: Uh, of course
Steve walks to the kitchen and comes back with a beer
Steve: There you go
Natasha: Thank you
Natasha kisses Steve
Steve: What was that for?
Natasha: I'm kissing the next person who walked in the room
