you're Bucky's girlfriend

the avengers decided to go to Disneyland and Bucky bought you with him. You guys are walking down the streets of Disneyland as Thor points to a food restaurant

Thor: "my favorite rollar coaster!"

the avengers laugh and walk to the food place. They sit down on a big table with each other and you sit between bucky and loki. Bucky looks at you and gives you're lips a quick peck

Bucky: "do you want anything, baby?"

he asks in his gentle voice. Making loki jealous.
