I really like this one-shot it is one of my favorites that I've written, and yes the infamous Agent Green is present.
Please read and review.
Third Person POV
Clint leaned against the kitchen counter waiting for Natasha's return from her latest solo mission.
"Hey Clint, will Natasha be home soon?" Bruce questions kindly grabbing a water from the fridge.
"Yeah, she should be here any minute." He responds checking his watch again.
"You know a watched clock won't bring you're super-secret, ninja girlfriend here any faster." Tony's taunting voice flew through the air, like nails on chalk board to Clint.
"For the last time Stark, Nat and I are not dating." He grumbles, while the duo take seats on the bar stools in front of him.
"I don't believe him, do you Brucie?" Tony questions earning twin eye rolls from the men.
As Bruce begins to open his mouth, the telltale rumble of the walls announces the jet's touch down. Less than a minute later, the door to the kitchen was being thrown open so forcefully Tony nearly fell from his chair.
"That sunset was almost as beautiful as you, Natasha." Agent Green spoke trying to be smooth.
"You do realize, Agent Green, that you have for all intents and purposes just infiltrated Avenger's Tower and Fury did sign off on me killing any infiltrators." Natasha threatened venom dripping from her words.
"It's not infiltrating if you let me in." He rallies back
"I never knew slamming the door in your face was an invitation. Excuse me while I invite you with my fist." She replied irritably.
"Whoa, whoa, no blood shed in the kitchen, lovebirds. Take it upstairs." Stark teased, watching Clint's face twitch in masked jealousy.
If looks could kill, there would be two dead bodies in the kitchen.
"Oh for the love of…" Natasha mumbled under her breath, before getting an idea, "The threat of death won't stop you, but maybe this will." She says quickly as she glides to Clint's side, pressing him against the counter in a heated kiss.
Pulling away after a long moment, Agent Green's voice broke their silent moment, "I won't give up, you'll come around some day." He says with a smile and makes his way back to the roof.
Natasha grabs her gun whipping around to follow the agent before her partner's arms drag her back to him in a kiss. Blind to the outside world, they miss the hasty retreat of Bruce and Tony.
Pulling away slightly, Natasha huskily speaks, "Remind me again why I can't kill him?"
