That's it, you little slut! Eat my pussy! Mmmmmmmmm yesssssssssssss, eat the pussy of your Mistress Sif! Oooooooooooh fuck, good girl." Sif lovingly stroked Wanda's hair as she continued providing her with encouragement, "Ohhhhhhhhhhhhhh yeahhhhhhhhhhhhh, lick that cunt like the lezzie whore you are! The lezzie whore I made you! Oh shit! Just like that, mmmmmmmmm fuck yeah, just like that! Oh fuck! OH FUCK!"
Natasha Romanoff smiled warmly as she watched Mistress Sif get what she so richly deserved. Or at least, one of the many, many things. Because honestly, getting her cunt licked wasn't really enough for that literal Goddess who deserved so much more. Like three other bitches, one to eat her ass, and two more to suck her tits. And Natasha would very much like to be one of those bitches.
Especially given that it was very likely that afterwards, Mistress Sif would reward who worshiped her with a butt fucking or two. After all, that's exactly what she had done before. Many times, at this point. And The Black Widow was literally aching for the same treatment, which was why she found herself standing outside of her owner's bedroom, peering in longingly.
However, on this occasion, Natasha hadn't been summoned, or yet been noticed. And what she was sure that her inclusion would be welcomed, more than anything else, she wanted to please Mistress Sif, and sometimes, that meant leaving her alone with her favourite. Especially as it wasn't like there was a shortage of other beautiful women that The Black Widow could go too.
Then again, there was something to be said for just watching. Hell, Natasha was pretty close to letting her hand slide downwards, until she sensed that someone was watching her from the shadows. And in the middle of the night like this, even the infamous Black Widow had her limits, and she just couldn't see who it was. Or maybe, what it was.
There was a very, very good chance that it was simply one of the new girls, especially one without powers, who was simply too nervous to approach her. However, the training she received from The Red Room had Natasha slowly, and as casually as possible, making her way down the hall, moving closer to the sound, but without making it obvious that was what she was doing.
She was right to be cautious, as when she reached her destination, another Black Widow jumped out of the shadows, and stared at the most famous member of The Black Widow program. Natasha stepped back, waiting for the other woman to make the first move. And she wasn't waiting long. No, all of a sudden, she found herself locked in a battle of counter holds and strikes, which had her heart racing.
Don't get her wrong, Natasha loved her new life. She really, really did. But God, she had missed this. So much so, she was about to beg Wanda, and more importantly Mistress Sif, to let this play out, as she sensed them both reluctantly pull away from each other, and go to check on the noise that was coming from the hall. However, before they were spotted, the other Black Widow grabbed a firm hold of Natasha, activated some kind of device, seemingly designed to disorient an opponent.
It definitely worked, as the most famous Black Widow was left feeling dazed and confused of why everything was suddenly different. Then she realized they were in a bedroom, likely as a result of teleportation. That was the moment, the two assassins rolled away from each other, and turned to face each other, only for the other competitor to remove her mask, revealing a familiar face.
Namely, that of Yelena Belova, who smiled warmly and greeted, "Hello, sister."
"Yelena!" Natasha exclaimed, for a moment unable to hide her joy at seeing her undercover sister, before forcing her face back into a neutral expression, "What are you doing here?"
"Do I need an excuse to see my sister?" Yelena quipped.
"I told you, I don't like you calling me that." Natasha grumbled.
"Which is why I do it. At least partly." Yelena confessed with a soft smile, before pointing out, "But, to me, that's what you always will be. I know, I know. We were undercover. It wasn't real. Or at least, that's what you tell yourself, because you're afraid to care about anyone. Especially someone like me. But you remember, don't you? How you were protective of me? How you literally tried to sacrifice yourself to save me?"
"Yeah, and how did that work out?" Natasha questioned bitterly.
"Well, we're both alive, aren't we?" Yelena countered, a grin crossing her face, "And thriving. Ooooooooooh yessssssssss, Natasha Romanoff is finally living her best life. And everyone knows it. Ohhhhhhhhhhhh yeahhhhhhhhhhh, everyone has seen the deadly Natasha Romanoff be reduced to nothing but a lesbian anal whore. And I have to say, it's a look which suits you, sister."
"Yelena, I..." Natasha began, actually blushing as for the first time in a long time, she was embarrassed about her behaviour.
"No, no, no, don't be embarrassed, sister. This is what you were always meant to be." Yelena reassured, taking a cautious step forward as she continued, "Mmmmmmmmm yesssssssssss, Natasha Romanoff was always meant to be someone's anal bitch. We all were. Mmmmmmmm yessssssssss, all Black Widows love being butt sluts, owned by superior women. Especially me..."
Natasha gasped, with a mixture of shock, horror, and if she was honest, arousal, as Yelena emphasized her words by pulling her pants down and spreading her cheeks, revealing that her butt hole was gaping obscenely wide open. Something she'd seen a dozen times, including in a mirror. Or a picture. Or just watching footage of herself back.
So it was really hypocritical of her to be disappointed in Yelena for allowing herself to be debased in this way. But she just couldn't help it. As the other Black Widow had just pointed out, Natasha was always protective of her 'sister'. So to see her like this was heart-breaking. And yet, at the same time, it was also a turn on, one which made her heart race, and her slutty little ass hole quiver around the butt-plug, which was inside it.
