Maria Hill had promised herself, and sworn to anyone who would listen, that she wouldn't run and she certainly wouldn't hide from the psychotic alien known as Sif. It was mostly because she refused to show how afraid she truly was, but she also wanted to inspire the people who worked for her, especially the women. After all, she was The Director of SHIELD dammit, a seasoned veteran of war, covert affairs, and worst of all politics.
She wasn't some noob! She had fought and defeated aliens before, both from behind her desk and out in the field. And if, or most likely when, Sif came for Maria would go down fighting. To her shame she broke both those promises, but only when it was too late.
To make matters worse Sif didn't have the decency of snatching her in her sleep, or teleporting into her office, or any number of the ways that Maria had imagined she would try and take her. No, Sif walked into the most highly fortified base that SHIELD had, brushing off the most skilled agents like they were nothing and not even blinking as Maria frantically ordered everyone to hit Sif with everything they had.
Yet even as Sif walked through the base like some kind of monster from a slasher film, albeit where no one is killed, Maria refused to leave her post as she frantically thought of a way she could get out of this, only retreating to her office when Sif was nearly at the command centre.
Despite having seen Sif brush off bullets like they were nothing Maria still pulled her pistol from out of its holster and pointed towards the door. Partly out of habit, and partly because it was just weirdly comforting. Although she didn't even bother firing it when the door to her office was torn off its hinges, revealing Sif's smiling face.
For a second Maria considered turning the gun on herself, just as a 'fuck you' to Sif, and to avoid the humiliation that was coming. But she didn't want that to be how her tenure as Director ended.
She'd thought too long and hard to get this job to go out like that within the first week of finally getting it. So whatever it took she would simply resist Sif's influence, Maria stubbornly told herself. Or maybe that was the influence taking hold.
Either way Maria dropped her gun and grumbled, "Sif."
"Please, all the women of this world should refer to me as Mistress Sif." Sif grinned as she entered the office, "Or did you not see my broadcast?"
"I saw it, and I'm afraid I have news for you..." Maria said boldly, "You will never win. No matter what happens next, SHIELD will find a way to defeat you."
"How?" Sif questioned, genuinely sounding curious, "The old men who run this world already threw their missiles at me, and my beloved Wanda caught them, through them back and just before they were about to hit I had her sent them to space. All of them. Now they have no idea what to do. I don't need my mindreader to tell me that. I have single-handedly defeated The Avengers, and now SHIELD-"
"You haven't." Maria interrupted, "This is just one base. We have lots more."
"Yes, all with beautiful women for me to enslave." Sif chuckled with delight, "Mmmmm, I look forward to it. Yes, it will take me a while to enslave you all, but what's that phrase? Ah yes, cut off the head of the snake. And what a lovely little head you are. Do you think that's why you have this position, Maria? Because I do. Mmmmm yes, I think the old men who run this world knew I wouldn't get the same satisfaction from inevitably defeating SHIELD if Nick Fury was still in charge, so they replaced him with you as a sign they're willing to cooperate with me and hand over the most beautiful and strong women they have to me on a silver platter, just like you."
Unable to hide the fact that she was shaking with rage Maria growled, "You're wrong."
"Am I?" Sif grinned, "I suppose even when you are broken the stronger SHIELD agents will still have some fight left in them, but most of the women in your organisation, and indeed all over the world, will accept their fate once they have witnessed the strong, and stubborn The Director of SHIELD Maria Hill be broken and turned into what she was always meant to be, just another slave of Sif."
"That. Will. Never. Happen." Maria growled through gritted teeth, "I will never be your slave. I-"
"Wanda!" Sif suddenly yelled, the girl in question appearing in a flash, eyes and hands glowing red as she began to work her magic, "As I said your breaking will be seen by all of SHIELD, but in a few moments we shall go live on every channel on every television set around the world, just so that everybody knows that this is the moment the women of this world fall to me. But as I said in my first public broadcast, I shall leave the human race their old, their young, and just enough women to survive. I shall however take every last woman like you Maria, and in time you will see it as an honour, and blushed at the thought that you ever resisted me. Now, to start the show, how about we show the world what has become of the only female Avenger, the deadly Black Widow Natasha Romanoff."
As Sif spoke television cameras appeared out of nowhere all over the room, followed by the woman that Maria love, causing the usually stoic SHIELD director to softly cry out, "Nat."
After a moment's hesitation Maria ran to her lover and cupped her face, causing Sif to grin and taunt, "From what Wanda tells me you would be very proud of her. She's the most stubborn woman I've ever met, clinging onto her free will even after days of brutal butt fucking. Mmmmm, oh yes, I butt fucked her, spanked her, and made her eat my pussy for hour after hour, day after day, and still she won't submit. Truly a marvel. Breaking her will be my greatest triumph. Perhaps I shall even achieve it today, as I break you in front of her."
Maria barely listened to this taunting as she was too busy examining Natasha, bound to a BDSM device she looked half dead at first glance. Which seemed to be true on further examination, but not because she had been poorly treated, but because as Sif boasted she had been just so relentlessly fucked that she was completely exhausted.
