Rational Writer Me: Okay, Natalia, you need to come in and provide some spy stuff exposition for purposes of the plot.
Natalia Romanova (aka Natasha Romanov aka the Black Widow): Okay, but only if I get to sleep with Steve.
RWM: Bzuh... what?
Nat: You heard me.
RWM: You don't want to sleep with Steve! When have you ever wanted to sleep with Steve?
Nat: I had UST with him in the mid-'90s, and I produced his sprog in The Next Avengers.
RWM: That's hardly firm canon.
Nat: And Virgin!Tony and Virgin!Daken are?
RWM: Look, I already have Sharon in this story. Why don't I just swap you two. You can ride unicorns, and Sharon can be a spy who has a thing with Steve.
(Sharon: But I like riding unicorns. RWM: More than you like Steve? Sharon: ... maybe?)
Nat: Would I have to be a virgin?
RWM: Well, yes.
Nat: As you Americans would say: Screw that.
RWM: But don't you see, it can't just be a one-night stand. Steve's not that kind of guy; he only puts out for committed relationships.
Nat: I have no problem with that.
RWM: I don't suppose you'd be willing to break up with him in the end?
Nat: Nope.
RWM: But... but... but it's a Steve/Tony Story!
Nat: Not any more.
And that's how this monstrosity turned into a threesome.
ETA: Now she's demanding an NC-17 rating. -sighs- If you give an inch, they'll take a foot, and next thing you know: you don't have a leg to stand on.
