The first time that Yelena sat in Natasha's lap since they were children in Ohio was one afternoon when Yelena returned from her trip to the nearest convenience store where she had gotten one of those cheap crushed ice smoothie things. Natasha had been working out and had just finished changing her clothes when she sat down in Yelena's favorite armchair. Yelena walked through the front door shortly after she took the seat.

"Welcome home…. Were they out of the smoothies?" Natasha questioned hopefully as she heard Yelena dropping her bag on the table. Yelena laughed humorlessly and Natasha could not help the grin that came onto her face in response to the girl.

"Nope. The machines were full, and I got a cherry-flavored one," Yelena responded, and Natasha's smile dropped as she scrunched her nose in slight disgust.

"Gross," Natasha expressed wholeheartedly.

"You just don't know what tastes good," Yelena shot back as she entered the living room, pausing immediately just in front of the armchair that Natasha was currently slumped in. Natasha shifted her gaze up to look at the blonde who was currently staring down at her.

"That's my seat. Move," Yelena spoke, but Natasha could hear the slight teasing in her voice, and the redhead knew that she was just trying to mess with her.

"No. I'm resting," Natasha replied, closing her eyes as she sunk in more deeply in the armchair. Her muscles were aching from her particularly exerting workout earlier, and every part of her hurt too much. It made her realize that she was perhaps getting too old for this sort of effort.

"How is your butt taking up that much space? Move over and let me sit," Yelena informed her, and Natasha shook her head, reopening her eyes to look at Yelena in disbelief.

"There's a literal couch right over there," Natasha informed her, and Yelena just raised an eyebrow as she stared at her sister with a challenge in her eyes. Natasha reciprocated the gaze with just as strong of resolve as the blonde.

However, to Natasha's utmost surprise, Yelena just suddenly spun around and sat down on Natasha's legs, leaning back against Natasha's front. Natasha huffed in surprise, and Yelena just happily sucked on her smoothie.

"What are you doing?" Natasha asked, and Yelena shrugged.

"Sitting in my spot."

"Well, it looks like you're sitting on me," Natasha bluntly informed her, and Yelena shifted her weight so that she was settled more heavily on Natasha. Natasha grunted with the force.

"It feels that way, too," Natasha added, her voice a little strained, and Yelena just wiggled so that she was more slumped against Natasha's body and her head was resting just above Natasha's shoulder as her rear end settled between Natasha's legs comfortably.

"You're not very comfortable," Yelena informed her, getting another swig of her drink as she flashed her honey-green eyes in Natasha's direction. Natasha sighed deeply, a façade of aggravation on her face but her true emotions reflecting nothing of the sort.

"Then go lay on the couch," Natasha replied, but there was no real venom or insistence in her voice. It was mostly defeat since she knew how this was going to end. Yelena wanted to sit in that location and she definitely was not going to give in.

Yelena just shook her head, snuggling closer to Natasha. Natasha just groaned before resting her head against Yelena's shoulder and closing her eyes as Yelena watched the television with the sound turned down on it. She pulled her arm up and around Yelena's waist as she pulled her back against her.

Natasha knew her sister was just being stubborn, but Natasha was not going to let that get in the way of Natasha herself enjoying the close contact with her favorite person in the world.

…

The second time it happened, Natasha was trying to have an adult, civilized conversation with Clint Barton on her phone. They were facetiming because his kids had wanted to talk to their Auntie Nat, and she was much too soft-hearted toward them to turn them down, despite the fact that she did not enjoy facetiming at all.

However, just when Clint had gotten the phone back and had started talking to Nat by himself, Yelena chose that moment to strike.

She came up to the side of the couch where Natasha was sitting, staring at her insistently. Natasha just ignored her, continuing her conversation with Clint. She could feel Yelena's glare more than she actually saw it, but if she focused on her peripheral vision, she could definitely see the furrowed eyebrows.

She motioned to Yelena to tell her to give her a moment, and she could tell from the change in Yelena's posture that this was not going to be good enough for her.

But Natasha kept her focus on Clint. She could worry with Yelena's drama later once she was off the phone.

What she did not count on was the fact that Yelena was going to just plop down in her lap, squishing one of her arms that was holding the phone up which caused the phone to fall out of her hand. Natasha let out a noise of surprise, and Yelena just relaxed there, a giant smirk on her face as she eyed Natasha wickedly.

"Clint, hang on! Yelena, what in the—"

"I needed you to pay attention," Yelena told her simply, and Natasha rolled her eyes.

"Why?! What is it?!" Natasha demanded, wondering just what would warrant Yelena so rudely interrupting her and Clint's conversation. From Yelena's giant, cheese-eating grin, Natasha assumed that it was very likely a reason that was not worth all of the drama that Yelena had taken upon herself to create.

"We're out of sour cream and onion potato chips," Yelena answered her simply before cackling. Natasha just groaned deeply, and she could hear Clint laughing from the phone's place in the floor.

"Are you serious?"

"Yes! They're my favorite and I needed to make sure you got them on the grocery list,"

"It could've waited, though," Natasha informed her, bending around her and grabbing the phone that had hit the floor. She was not really angry with the blonde, but she was slightly aggravated by her love of annoying the redhead.

"No, it couldn't have. Sour cream and onion is the best in the world and the fact that we have no more is an issue of Avenger-level importance," Yelena declared, and Natasha sighed in slight irritation as she held the phone up so that it was above Yelena's shoulder and facing Natasha.

Clint was grinning widely.

"Sounds like you need to get off the phone and go get her some potato chips," Clint told her, and Yelena's grin was as big as his. Natasha rolled her eyes and rested her chin on Yelena's shoulder since it was so conveniently there to serve as a chinrest.

"Yeah, Natashka. I'm hungry," Yelena informed her, looking over at the older woman. Natasha shifted her gaze from the phone over to Yelena's adoring gaze which, of course, the blonde likely did not know looked so loving when she was trying to be irritating.

"You're always hungry," Natasha shot back, but her words did not possess the fire that she halfheartedly attempted to summon into them.

"Hey, look at that, she's got something in common with you, Barton," Natasha added, raising an eyebrow at the man on the phone. He deflated a bit as she chuckled at his reaction.

Yelena snuggled in a little further, making her own quip, and Natasha could not help but notice how comfortable the younger girl was in this situation.

Of course, Natasha could not say anything since she was just as contented as the blonde.

…

The third time it happened, Natasha was peacefully sitting and quietly enjoying Melina's company as the woman busied about in the kitchen and was working to serve dinner for their weird, dysfunctional little family.

"Hello," Yelena suddenly interrupted the atmosphere, marching through the door as if she had a definitive purpose and reason, and Melina turned her head with a slight smile.

"Hello, dear," Melina kindly replied, warmth in her voice as she addressed the girl. Natasha just smiled lovingly at her younger sister.

"Hey, little one," Natasha greeted, and Yelena narrowed her eyes as she stared at Natasha. However, there was an unhidden adoration in her gaze as she eyed the redhead. Natasha quirked an eyebrow, wondering what her younger sister was about to say to her.

"I've got a bone to hack with you. I heard that you said—"

"Pick," Natasha interrupted, barely holding back a laugh as she relaxed in her chair, noting Melina's disapproving glance at the slouching. Natasha was convinced that she was not slouching, but she straightened just a little to avoid Melina's chastisement. Yelena immediately looked confused at Natasha's interruption, and she blinked at her.

"What?" Yelena questioned, her voice conveying her cluelessness.

"A bone to pick. You said hack," Natasha corrected, and Yelena narrowed her eyes. Natasha had to bite her tongue to keep from laughing at the younger girl's expression and overall irritation with Natasha.

"Whatever. I heard that you said I was not cute anymore," Yelena informed her, and Natasha suddenly realized that the girl looked almost offended about the whole thing. Natasha might be slightly more worried about it if she did not remember the exact words she had uttered and knew that Yelena was blowing it way out of proportion.

"I said you were all grown-up and not that same cute little girl anymore."

"SEE!" Yelena proclaimed accusingly, pointing her finger at Natasha, and Natasha just grinned in reply, feeling the urge to reach out and grab Yelena's adorable chubby face that was shoved near Natasha's own as she glared at her with that typical challenging expression.

"I also said you're very pretty now," Natasha added, and Yelena just sniffed with indignation as she looked away from the redhead.

"She doesn't think I'm cute anymore," Yelena announced to the room, her arms crossed, and Natasha just huffed a bit with laughter. Melina shook her head, choosing to avoid getting involved in this drama. However, judging by the barest hints of a smile on her face, she was enjoying the exchange.

"I meant you're just not a little girl anymore," Natasha explained, feeling a bit of laughter bubbling up. Yelena narrowed her eyes.

"Well, if I'm cuter as a little girl, I'll behave like one then," Yelena proclaimed before suddenly sitting on Natasha's lap. Natasha huffed but wrapped her arms around Yelena's waist to keep her in place.

"You already behave like one. Look at the fit you just threw," Natasha pointed out, and Yelena just leaned back so that she was squishing her shoulder against Natasha's face in defiance. Natasha turned her head to the side, chuckling with a wide grin as she held onto the blonde.

Natasha was beginning to think that Yelena just wanted an excuse to sit on her lap.

…

Natasha's theory was fully confirmed when they were sleepily watching a movie, and Natasha's eyelids were growing heavy. Yelena was right by her side, and her sister's warmth was starting to lull her out of consciousness.

In fact, Natasha was almost asleep when she suddenly felt a weight starting to move into her lap.

She was dangerously close to opening her eyes in the midst of her somewhat confused and disoriented state, but she kept them shut as she waited to see what Yelena would do.

To her surprise, Yelena wiggled her way very carefully into her lap, curling herself into a ball as she rested her head on Natasha's shoulder in the crook of her neck. Natasha's heart immediately melted with the girl's touch and the love that she was obviously too worried to show while Natasha was conscious or seemed to be.

Natasha waited a few moments longer before snaking her arms up and around Yelena. Yelena stiffened a tiny bit, frozen and almost seeming as if she were waiting on something. Natasha hummed under her breath with contentment, pressing a small kiss to Yelena's head.

"Mmm… Y'know, if you wanted to sit on my lap, you could've just done it a while ago," Natasha informed her easily, her voice rough with sleep. She felt Yelena immediately loosen up in response to that and the blonde's arms wrapped more tightly around Natasha as she nuzzled into the redhead's neck.

"You said I was not the same little girl, and we did this kind of thing when we were small," Yelena replied in a mumble, and Natasha could feel the uncertainty coming off of her in waves. Natasha shook her head, a smile tugging at her lips.

"Little one, you'll never be too big to sit in my lap,"

"I'm bigger than you," Yelena informed her, and for once it was not even in her typical condescending, smug tone that she always took when the topic of their height was brought up. It had a significant undertone of insecurity and slight shame.

"By one inch," Natasha quickly replied, and Yelena chuckled a small bit before quickly falling silent.

"Besides. I thought you said you didn't mind touching in public."

"I don't. I just worried that you would not want me sitting on you like a baby," Yelena informed her, her accent growing thicker, and Natasha was almost sure that she was about to transition fully to Russian. It was something that the blonde always did when she was feeling insecure or was uncomfortable with something she had to say. However, the fact that they were alone must have contributed to the reason she remained speaking English.

"I always want you close. I haven't been able to hold you like this for over twenty years. I don't care how old you are. I want you close to me and you don't have to have an excuse for it," Natasha informed her, and she could hear the small sniffle that sounded off somewhere near her neck. She could also feel the slight wetness against her skin.

"Ya lyublyu tebya bol'she vsego ili kogo-libo," Natasha admitted to her, and she could feel the smile pulling at Yelena's lips. Natasha knew what it meant to the girl. It was something that Natasha herself had wanted to hear from someone for so long after she was able to escape the Red Room.

"Ya tozhe tebya lyublyu."

A/N: Gosh, I'm so soft that I should be ashamed of myself…. But I'm not… Unfortunately… XD
