"So, Agent Carter..." Sif smirked wickedly, savouring this moment, "Are you finally ready to become mine?"
Peggy Carter gulped and then stood frozen to the spot for a few extremely long seconds, which was very, very telling. Which of course made Mistress Sif smirk even more, which made part of Peggy want to punch her in the face. It was the same part of her which was screaming at her to say no, which was the obvious answer, and she was absolutely disgusted with herself that she was even pausing to contemplate an alternative.
But she just couldn't help it. Not after spending an entire week of absolute bliss with her beloved best friend Angie fulfilling her every sexual whim. And God help her, her niece Sharon doing the same. And she wanted to say no, she really did, but how could she possibly give them up?
They had been expecting Mistress Sif's arrival, so Peggy had been standing patiently in the centre of her room while each of HER slaves were kneeling either side of her. She glanced to them now, and while Sharon obediently had her head down Angie was staring up at her pleadingly, obviously silently begging Peggy to submit, much like she had been doing all week, so the three of them could truly be together as slaves of Sif.
Saying no would break Angie's heart, and her own, and Peggy just couldn't say no. But she wasn't sure she could say yes because she knew what that meant, especially as Mistress Sif was joined by her more dominant slaves, like Wanda, Gamora and Nebula.
Desperately trying to find an alternative Peggy leaned forward and whispered, "Can I speak to you privately?"
"Whatever you want to say to me, you can say in front of my slaves." Sif grinned.
"Please?" Peggy pleaded after a few long seconds, and then after a few more she reluctantly admitted, "I wish to discuss the terms of my surrender?"
There was an adorable squeal of happiness from Angie, which even Sif had to acknowledge with a soft smile, but then she firmly explained, "This is not a negotiation. We discussed the terms of your surrender before, and they remain the same. If you can survive whatever happens next while still wanting to dominate your precious Angie, and your niece, they're yours.
Understanding of course, whatever is yours, is mine. That means I can use them whenever I want, even if you're in the middle of doing so. Of course, that's assuming I don't break you entirely, which is a high probability given that you're a stubborn goat who shall require a lot of special attention to truly break. Now, are you ready to submit? Or shall I take your toys away, and leave you to contemplate a little more?"
"No! I'll..." Peggy protested, unable to even consider the fact that she wouldn't be able to play with her pets anymore, "I'll do it."
"Excellent." Sif grinned.
"On one condition!" Peggy added quickly, her mind whirling, "If you're so confident that you'll break me, then let's put it to the test. If you can truly make me submit, I'm yours forever. But if I can resist this entire night, then you let me and my pets, Angie and Sharon, go. And you and your minions never come after us again."
There was a brief pause, then Sif burst out laughing, "Oh Peggy, I truly admire your fighting spirit..."
"So, we have a deal?" Peggy cautiously asked.
"Yes." Sif grinned, "Not that it matters, because before the end of the night you shall be mine."
"We'll see." Peggy said boldly.
"Yes, we will." Sif smirked, before ordering, "Wanda? You know what to do."
"Yes Mistress Sif." Wanda quickly replied and obeyed, her eyes and hands already glowing red.
Lifting those hands into the air Wanda Maximoff flooded the room with red mist, which was probably more for dramatic effect as Peggy had seen her teleport without it, and then when it cleared they were in a much, much bigger room. It was cavernous, and familiar. Of course, it was one of the headquarters of SHIELD, the organisation Peggy had fought so hard to build. Her legacy.
