Author's Note:
The following events take place during the first Avengers movie.
Most of the movie's events remain the same unless otherwise stated, though I may reorder some of the chronology for the sake of pacing. I jump around through the story so this works better if you remember the movies well.
Of course, Marvel owns all the rights to these characters, and there will be spoilers for the films involved.

As Natasha stood, exhausted, on the rooftop of Stark Tower, she wasn't sure what would happen next. She hadn't expected aliens to flood the skies, nor had she expected Bruce to return, apologise, and use his power for good - even if she did know he had it in him. Whatever happened next was up in the air, and she felt a little powerless.
It all felt futile, but with the lives of the entire planet at stake, she knew she couldn't rest - even for a moment. Especially now that she had an idea on how to put an end to all this destruction, she thought as she eyed the weapon in her hand.
Loki's sceptre, the very thing that had brought such chaos into her life, may be the key to saving the day. Even if it was just for a moment, luck was on her side, as Eric Selvig was on hand to give her some much-needed information about the device he had helped create while under the influence of Loki's power.
Selvig, with some of his mind still intact, had built in a fail-safe to cut the power source in the same machine that now kept the portal open, spilling countless alien warriors into their world. All they needed was Loki's sceptre, and Natasha was able to retrieve it from the balcony below, thanks to Banner's quick disarming of the Asgardian.
She held the staff in her hand, trying not to think about what it was capable of, and pushed it forward, slowly edging it through the force-field protecting the tesseract. As she brought the point of the sceptre closer, she started to feel further away, as if the cube was pushing her away, in both body and mind.

Natasha was thrown to her knees, but instead of the hard ground of the roof, her knees and hands met the soft wool of a rug. Instead of the blustering wind atop a skyscraper, she felt the still, warm air of a room, draped in royal colours and lit by a fireplace. Touching her arms, she felt her black uniform still, but everything else had changed.
Looking to her right, she saw him, sat there on a golden throne. Loki, in his full Asgardian garb, horns and all, was relaxing in his seat, smirking at her. Looking over her shoulder, Natasha spotted two Chitauri soldiers, presumably the ones who had brought her here; a prize for the man that had conquered the Earth.
"The last time we met," he said. "I told you to enjoy the rest of your day. I hope you did. The last few hours that humanity had as their own rulers must have been sweet, but eventually it gave way to a higher form of freedom."
Natasha, too tired to stand up, let alone fight her way out of this situation, glanced to the throne. At Loki's feet was Thor's hammer.
She had no quips to throw his way, just the feeling of absolute defeat. And with that feeling, she began to slip, losing her grip on the person she was on the rooftop in New York. Now she was just here, captured, long after the battle of New York was lost, a soldier in a flailing rebellion, forgetting the woman she used to be.
"What exactly is it that you want from me?" she asked, knowing that he could have had his armies take her down in the field. "Do you really want to gloat this much?"
He smiled, his irritation giving way to amusement.
"I told you once, about a festival, Thurseblot, in which my people would visit this lowly planet, and take all the women or men that they desired. You said I would not be invited to any more such banquets in the royal halls of Asgard... and you were right."
He leant forward in his throne, pausing before he took pleasure in the following words.
"But, as rightful king of Midgard, I can begin the festivities anew."
Behind her, Natasha heard the sound shuffling armour, and turned around, befuddled. As she swivelled on the spot, she saw three of Loki's soldiers, the grey-skinned aliens Loki had employed in the Battle of New York, as they began to undress.
With their combat plating removed from their lower half, they revealed more of themselves than she expected. Their large, flaccid penises were nowopen to the room, and Natasha's eyes desperately searched the room for an escape route.
"Don't waste your energy, there's no way a mortal woman could get out of here, especially in the state you're in."
Two of the Chitauri took a step towards her, their dicks swinging slightly as they made their approach.
"This doesn't seem like you're style," Natasha said, looking for any angle she could, "where's the fun if I don't have a choice?"
"You are very perceptive, aren't you, Romanoff? You understand that I like games, but that won't stop me from getting my revenge, and showing you the light."
"The light?"
"I would like to take you, and fuck you hard, as I should with my property. But I would rather wait until you break, and ask me nicely - beg me - to have my cock."
"Not gonna happen," Natasha said, still too breathless from weeks on the run to crack wise.
Loki didn't answer, but instead started to unbuckle himself, lifting a strip of fabric to one side. From underneath, his penis sprang to attention, already hard. Without so much as a smirk, he lifted his left hand from the arm of his throne to click his fingers once.
Natasha heard a door creak open, and her eyes widened in shock as she saw a familiar face walking towards them. It was none other than Pepper Potts... without a thread of clothing on her body.
As she came near, Natasha spotted a leather collar around her neck. She glanced down at Natasha, and blushed deeply, before averting her eyes back to Loki. Without a word between them, she got down to her knees beside him, and leaned over his leg to hold his dick in her fingers.
Pepper held the base of his shaft, stroking it lightly for a moment, and watching it with concentration. She licked her lips and leant forward, but just as her lips were just about to reach the head, he pulled her back by her collar. She looked up at him like a lost puppy.
"Not yet, pet. You must have permission first."
Pepper's cheeks became even more red, and she anxiously looked to Natasha again, then back to what was in her hand. Her mouth hanging slightly open with desire, she swallowed, and began to speak.
"Master, may I please suck your cock? I want to feel your hardness in my mouth, in my throat... I want you to fill my mouth with your cum. Please, sir..."
She trailed off, and Natasha couldn't believe it. These weren't the words of the Pepper she knew, nor did it seem forced. Loki nodded and patted Pepper on the back of the head, and she eagerly returned to her duty, taking his cock into her mouth, moaning as she did.
"This one was once like you, defiant. But all minds falter in the end - even stubborn ones like yours. The minute you accept your place, knelt before my soldiers to service them at my command, you will know peace."
"I think I'll stick with the running and gunning, personally," Natasha replied, eyeing Pepper's movements before her, perplexed.
"The old abandoned subway station, not detailed on any existing maps or documentation, around 3.24 miles from here. Four access points, 200 inside."
Natasha looked away from the enthusiastic blowjob before her to Loki's face, her heart dropping. These were the exact details of the survivors' current base of operations.
