"I'm quitting life," Yelena dramatically declared out of the blue, still dressed in her usual cargo pants, combat boots, and tank top combo with her hair pulled back in a ponytail despite the fact that Natasha had already told her to change at least five times already. It was a stark contrast to Natasha's apparel which was currently a sleek black dress that stopped just above her knees and dipped down in a heart-shaped neck cut.

Natasha rolled her eyes fondly, only slightly irritated with Yelena's lack of cooperation. By now, she was mostly used to it, but it still could be terribly inconvenient sometimes.

Yelena's largest contributor to her belligerence was that she did not want to go to the party that the Avengers were hosting tonight. While Yelena wanted to talk to the team and keep making a good impression, she most certainly did not ever want to go to a hoity toity party with the richest, most influential people in the country.

Personally, Natasha did not really want to go either, but she was much more accustomed to such things despite her discomfort. She always went despite her own dislike for them even though Clint, Steve, and the others assured her that it would be fine if she didn't come a few times and took some time for herself.

She especially did not want to go because of the way that creepy older men drooled over her every time she walked by them. It made her terribly uncomfortable and reminded her far too much of her younger years.

It also reminded her of Dreykov and his disgusting ways.

"Hey, does my breath smell bad to you?" Yelena questioned before just moving directly into Natasha's face and exhaling deeply out of her mouth. Natasha quickly moved away from the blonde, choking a bit as she narrowed her eyes at the blonde. Yelena grinned widely and wickedly, her eyes sparkling with mischief, and Natasha coughed hard.

"Oh, my— what did you eat?!"

"Tuna fish," Yelena told her as if it were the most obvious thing in the world, and Natasha swallowed hard, trying to keep the contents of her stomach in its proper place.

"Is it that bad?" Yelena questioned innocently before covering her mouth and nose with a hand and breathing out. She quickly withdrew her hand from her face and wrinkled her nose a bit.

"Oh, wow… That is pretty bad," Yelena admitted sincerely, but Natasha could see the easily evident smirk on the girl's face that the blonde was trying diligently to hide. Natasha just raised an eyebrow, completely unimpressed.

"Get in there and brush your teeth. We're supposed to be leaving in fifteen minutes and you aren't even dressed!" Natasha told her, trying to force some semblance of sternness in her voice to make Yelena listen to her. Yelena just sighed dramatically and deeply before heading off in the direction of her bathroom.

"Do I use the mouthwash after or before?!" Yelena called loudly after a few moments, and Natasha raised her eyebrows a bit as she looked through her things and ensured they had everything they needed to leave.

"Do it both times! You're going to need a double dose if you're not going to smell like that crap that you for some reason voluntarily eat," Natasha immediately replied to her, raising her voice so that the blonde could hear her.

"You know what they say to little kids about trying new foods?! It applies to adults, too!" Yelena yelled from her place in the bathroom, a playfully condescending tone to her voice. Natasha just huffed, a smile tugging at her lips as she chose not to grace Yelena's smart comment with a response.

"Ey, whaddya fink Ah should wear?" Yelena questioned, her words barely articulated. Natasha looked over her shoulder, taking in the sight of the blonde with a toothbrush in her mouth and foam threatening to dribble down her chin as she held up two different pantsuits. Natasha sighed deeply, looking down at her own dress before looking over at Yelena's options. Natasha finally pointed at the white pantsuit.

"That one matches mine," Natasha pointed at the one of her choice, and Yelena's eyes softened for a moment before she quickly masked it with her typical impishness.

"Too ba', Ah did'n wanta mat' wif you," Yelena told her defiantly, her words even more difficult to understand as she worked diligently to keep the spit and foam in her mouth, and then she spun on her heel, heading back to the bathroom. Natasha rolled her eyes, easily seeing through her sister's bluster.

Natasha checked the time, and she quickly noted that Yelena would need to hurry if the both of them were going to leave on time.

"Hurry it up!" Natasha called. "We've got to leave in about five minutes!"

"I'm hurrying!" Yelena responded, her words more discernable despite her distance from the redhead. Natasha with slight irritation noted the fact that the girl's tone was very much unhurried.

After a few more minutes and a dangerously close deadline to leave approaching, Yelena came ambling out of the room before plopping down on the couch, a pair of shoes in her hand that she dropped on the floor near the furniture.

Natasha hurried over to her quickly, aggravation starting to rise within her.

"Yelena, come on, we're going to be late if we don't leave now!"

"You know, that would be a true tragedy… Almost as bad as not going at all," Yelena informed her, completely unbothered as she sunk down further in the cushions with a big grin on her face. Natasha sighed deeply before grabbing her sister's arm and attempting to drag her to her feet.

"Get up," Natasha insisted, and Yelena groaned, letting her full weight rest on the couch as she fought her sister.

"I know you don't want to go, but—"

"You don't either. So let's just not go," Yelena proclaimed, and Natasha just stared at her, her light green gaze piercing Yelena's. Yelena held her stare, maintaining the challenge and firmly refusing to move.

After a long moment of staring at each other, Natasha quickly yanked her sister's arm, trying to take her off guard and force her up. However, as soon as she tried it, Yelena repositioned her arm and threw Natasha on the couch, the blonde now standing up over the redhead.

Natasha quickly started to get up, and Yelena dove for her, landing on top of the other woman full-force and trying her best to hold her down as she grabbed her with her legs. The two grappled with each other, Yelena trying to get a good grasp on Natasha's arms so she could hold her in place.

"Come on, you can do better than that," Yelena taunted, her voice strained and Natasha found that the girl was starting to get the upper-hand on her.

"I can. I just don't want to break the coffee table," Natasha pointed out, moving her head slightly in the direction of the table next to the couch where they were wrestling. Yelena breathlessly laughed in response to the older woman, still fighting her with all the strength she had.

"You might want to consider wearing a pantsuit, too. It allows for significantly increased mobility," Yelena said, her honey-green eyes locked onto Natasha's. Natasha grinned a bit in spite of herself, finding that this was quite fun. It was very enjoyable to just wrestle someone that she trusted so much and knew would not hurt her.

"Dresses are hotter," Natasha easily shot back, and Yelena shook her head, a wicked smile coming onto her face.

"Have you seen me in a pantsuit? People are like, 'Is there something burning in here? No, don't worry, it is just Yelena and her pantsuit,'" the blonde cockily proclaimed, poorly mimicking an American accent and deepening her voice, and Natasha laughed at Yelena, her grip weakening on her little sister.

Yelena took advantage of the opening and pinned Natasha's arms to the couch cushions. Natasha could not even really be angry as she just looked up at Yelena who had a wild grin on her face.

"Ha! Pinned you!" Yelena victoriously proclaimed and Natasha just smiled softly up at her, feeling her chest warm with fondness and pride as she just gazed at her little sister. The both of them sat there for a long moment, their chests heaving from the struggle.

Yelena seemed to sense the mood shift, and her victorious smirk faded just a little into something much softer and more adoring. Yelena loosened up a bit and carefully allowed herself to just lay her torso down on top of Natasha's, releasing her hold on Natasha's arms in favor of just relaxing on the redhead. Natasha brought a hand up, stroking Yelena's back gently before bringing her other arm up to bring her closer.

Suddenly, to Natasha's surprise, her phone suddenly buzzed. Natasha moved her hand from Yelena's back down to the pocket of her dress and withdrew her phone, tapping the screen lightly with her thumb.

It was then that she was reminded of the party that the both of them had to get to. The fun they just had was plenty enough to distract her from going. After all, she would much rather hang around the house with her best friend than go out and spend time with a bunch of high society snobs.

There on her phone was a text from Clint asking her if she was coming tonight or not. However, to her surprise, despite her insistence that she was going to come and bring Yelena, he had even added below it that he was perfectly willing to cover for her if she did not feel like going that night.

Natasha just gazed at the text for a long moment, and Yelena turned her head to see what her older sister was looking at. Natasha activated the keyboard function but did not type as she just quietly considered what she was going to write and what would be her choice. Yelena carefully watched the redhead's finger and Natasha could feel the hope radiating off of the Yelena.

Natasha finally sighed a bit in resignation, typing on the phone with her thumb and informing Clint that they would indeed not be coming, and it would be greatly appreciated if he could cover for her. She could feel the smile spreading across Yelena's face, and Natasha groaned as she repositioned underneath her sister's weight and moved up further. Yelena's chin was now laying on Natasha's chest and Natasha could look her in the eyes.

It made Natasha's heart squeeze as she took in the pure adoration, idolization, and devotion in Yelena's eyes. Natasha was almost sure that Yelena was not aware that her eyes were giving away that much emotion, but it was really nice to just see exactly what Yelena was feeling.

"Well, are you happy now?" Natasha asked even though she knew the answer to her own question. Yelena smirked a little, narrowing her eyes, but all of the emotion was still within them as she adoringly stared at the redhead.

"Very," Yelena replied simply, and Natasha huffed a bit with laughter, shaking her head and looking away for a moment before gazing back down at the lovable little urchin sprawled out on top of her.

"C'mon, let's get up and change into something more comfortable if we're staying," Natasha started trying to make a move to get up, but Yelena latched herself around her more tightly. Natasha raised an eyebrow, staring at Yelena quizzically.

"It's too comfy to move, and if we go change, the spot will get cold," Yelena protested, and she had that sweet pout that she had always been able to pull off so well. As soon as Natasha saw it, she knew that the blonde now had her wrapped around her finger. Natasha sighed deeply but she just chose to lay her head back and wrap her arms around the girl, enjoying the comforting pressure of Yelena's weight.

"Okay… But when your pants start riding up, you're going to be stuck here."

"Eh, a small price."

A/N: Another fluffy little oneshot to add to my repertoire, lol. I promise I'll try for something more angsty for these two soon, but I just can't resist the intense fluffiness. If I write something angsty, it's probably going to have a happy ending, so be warned… XD

Thank you so much for reading, and I hope you're having a good day! :)
