Imagine having a heated make out session with Natasha on the couch. When Nat was about to pull your shirt up when you heard a whistle. You two looked up and saw Tony standing in the corner of the room with a huge smirk. Natasha glared at him and stood up, pulling you up with her. The she kissed you roughly, grabbing your butt. You pulled away after a while, panting. "She's mine Stark. Fuck off." With that Tony left with a blush and tightening pants.
