Natasha P.O.V

I'm woken to the smell of coffee, wafting under my nose. I blink my eyes open and Bruce's lips press to mine, "good morning beautiful."

"Good morning, " I yawn and sit up, the blankets pooling around my naked waist.

"Last night was fun," he grins, handing me my mug.

"Mhmm," I hum, sipping the steamy beverage.

He reaches a hand up to fondle my bare breasts, "in for round four?"

"No, sorry babe, I'm sore, " I laugh and then pull apart his house coat, "besides, it doesn't look like you're ready either."

He chuckles and pulls the folds of the fuzzy fabric back together, "I was sort of kidding, though I could probably get up if I really tried, " he winks at me and then kisses my lips, "I'm going to take a shower." He slips off his robe and throws it over the bed, striding naked to the bathroom.

He's peeing when the door swings open, "Auntie, " squeals the baby as she launches herself into my bed, I have to hastily place my mug on the coffee table so she doesn't jostle it's contents and burn me.

"Good morning baby," I laugh and then call at Bruce, "you forgot to lock the door!"

"Oh shit!" He chuckles, looking over his shoulder.

"You naked Uncle, " Callie giggles, pointing at his bottom. "And Auntie naked," she says straddling my lap. "What deez called?" She asks, patting my breasts, and then pressing my nipple as if it were a button.

Bruce laughs out loud, "those are boobies!"

"Boobies!" Callie howls and then lifts her oversized night shirt revealing her skinny legs and torso, her bottom enveloped in a pull up diaper, "I don't have boobies."

"One day you will," I tell her, tickling her bare tummy. "Where's Daddy?" I ask, hoping to send her off to him until there's a little less nakedness happening in our room.

"Dada and Uncle Stevie sleeping."

"Together?" Bruce turns around quizzically.

Callie nods , "Uncle sad, so Dada cuddle him."

I glance nervously at Bruce, and he grimaces and shrugs. I decide to create a distraction, "Auntie has to go potty, do you?" She nods so I lift her up and carry her into the bathroom.

As she's peeing she stares unabashedly between my legs, "what's that?" She asks, poking my vulva, personal space does not exist in Callie's world, and I suppose it never really has.

"You're just full of questions today," Bruce laughs as he climbs into the shower.

"It's Auntie's vagina, " I tell her, and then promptly grab my housecoat off the hook to cover myself. Tony's been very clear that he doesn't want anyone having extreme reactions about nudity around Callie, so we all just let her ask questions while trying to maintain some modesty.

"Bajeena!" Callie says, looking down at herself on the toilet. "Uncles and Dada don't have those, " she scrunches her nose at me, and then glances at the shower.

"No you're right, they have penises."

"Beenitz," she nods seriously. "Uncle like boobies?" She yells at the shower and pats my chest.

"Oh yeah, " Bruce pokes his head out from behind the curtain and winks at me, I scoff and flip him off and then proceed to help Callie off the toilet and wash her hands.

"Uncle Stevie likes boobies?"

Bruce howls with laughter, so hard that I begin to worry he may slip, "yep! And so does Dada and Uncle Thor!"

"Oh!" Callie says, pushing her finger to her chin.

I begin to do my business and watch as the little girl runs and begins jumping on the bed singing, "I a little monkey jumpin on the bed!"

"Don't fall off and bump your head though!" Bruce yells, climbing out of the shower and wrapping himself in a towel.

"Okay silly Uncle!"

"Okay silly Callie," Bruce mimics, making the toddler giggle.

I'm just brushing my teeth when the song ends abruptly and the little patter of feet alert me of Callie's presence, "I hungry Auntie," she whines, tugging on my house coat.

"Okay sweetie, just let Auntie get dressed."

"No!" She wails and begins to cry, "I hungry Auntie!"

"Okay, okay!" I sigh, picking her up. "We'll go see if Daddy or one of your Uncles are in the kitchen."

The memory of starvation is still fresh to Callie, she's terrified of not having food, to the point of hiding snacks around the house and in her car seat. Banner has stressed how important it is to never tell her no when she's asking to eat.

Bruce follows us out and we walk down the hallway together, Callie resting her head on my shoulder and her fingers intertwining themselves in my hair.

"What do you want to eat baby?" Bruce asks, walking past me and opening the fridge. While she ponders his question, he fills a bottle with milk and hands it to me.

Callie requests eggs and then let's me cradle her while she drinks her milk. When she's nearly finished Steve walks in, his eyes relaxing when he spots the toddler, "there you are, " he gasps, looking at me with mild irritation.

"Uncle!" Callie squeals, sitting up in my arms. "Uncle, you like boobies?"

"Huh?"

I barely have time to register what she's asking before she's pulling my robe apart and singing, "taadaa!" With an exuberant smile on her face.

"Oh my god," Steve blurts and looks away.

"Callie! No, honey!" I pry her hands off and fix myself, but the little girl is instantly back tugging them apart.

"But Uncle likes booboos, look Uncle," she whines, and Steve glances up just in time to see another nipple flash out before I'm able to tuck it away.

His face heats and he looks away again, the embarrassed smile sneaking its way through, "Callie, no it's okay," he giggles and drags a hand over his face.

Meanwhile I'm fighting with the little girl's hands as she tries to release my breasts for the viewing pleasure of her Uncle, "Bruce help me!" I yell at the man behind me who is doubled over in fits of laughter.

"Okay, okay," he takes Callie and places her on the ground so I can fix myself.

"You see the problems you cause?" I hiss at him and he and Steve both chuckle.

"Uncle likes dem Auntie," Callie pouts at me, crossing her arms.

"Only Uncle Bruce is allowed to see Auntie's boobies baby, I'm not going to hold you if you do that." The baby frowns at me and stomps her foot.

Suddenly Callie gasps and rips the bottom of my robe apart, "Uncle you like bajeenas?"

Steve turns right around, I can hear him laughing but it's an incredibly uncomfortable sound, like he's overwhelmed and trying not to become aroused. I think I see him readjust himself before turning around again.

"Callie no!" I bark and close my robe.

She growls and pulls aggressively on the hem of my coat, "Uncle likes it!"

"No, it's okay baby, come here." Steve picks her up and shushes her.

Callie sniffles and leans her head on his shoulder morosely, "but Uncle and Dada likes boobies and bajeenas."

"No baby," Tony says, walking into the room, completely unaware of any of the happenings of the last two minutes. "Dada loves boobies and vaginas!"

"Tony!" Steve groans, but the smile in his voice is obvious.

Tony laughs, "now where are you getting all this important information hmm?"

"Uncle Brucie."

"Nice," Tony laughs, patting Banner on the back.

Callie lifts her shirt, staring at her bare chest, "I have bejeena but no booboos," she scowls and then looks apologetically at Steve.

He laughs and blushes, "no, not yet," whispers, kissing her tummy and then taking her shirt and lowering it.

"Okay, eggs are ready!" Bruce calls and we all find our spots at the table.

"Any plans for today?" I ask, looking up and down the table. When my eyes meet Steve I find him staring heavily at my cleavage, completely unaware of my question. I clear my throat and pull my night coat tight causing him to flush and avert his eyes as he mumbles an apology.

Tony chuckles and tousles Cap's hair before handing him and Callie both a plate. "I have the Barton's coming today to talk about the trip, organize food and shit. Figured the baby could play with the kids? Steve could you chaperone that?"

"Oh, I was planning to see my friend Sam today..."

Everyone turns to look at Cap in surprise and then Callie, who has zero tact, spins on his lap to gawk at him, "Uncle has friends?"

"That's what I was going to say, " Tony laughs.

"I have friends," Steve mumbles.

"I did not know that!" Callie says, shrugging dramatically.

"Well I do, you'll meet him later, " he tells her sourly and she kisses his lips, turning his scowl into a grin.

"Poor Stevie, " Thor booms, making us aware of his presence. Cap's smile disappears and he looks up nervously, Tony seems to notice it as well because he asks Steve what's wrong but he just shakes him off.

Stark shrugs and moves on seamlessly, "Thor can you watch the kids then today?"

"Yes for sure," he replies, sitting down in Callie's regular seat beside Steve, he then hugs the younger man's head and kisses it and then does the same to Callie who smiles up at him.

"Uncle like boobies?" She asks, gesturing at me and patting his shoulder.

He barks out a laugh, "uh, yeah, I do."

"Uncle Stevie likes boobies too, and Dada loves them!" She puts emphasis on the word love, and then reaches to her other side to stroke Tony's hair who is trying to contain his laughter.

"I'm confused," Thor chuckles, looking around the room.

"Bruce is teaching Callie all kinds of things," I roll my eyes and push my boyfriend's shoulder, my sleeve catching my cutlery causing it to clatter to the floor.

"It was funny," he grins sheepishly at me. I scoff at him and bend to pick it up.

I begin to eat my eggs again until we're interrupted by Callie gasping, "see! Auntie has booboos!"

I look down to see that nearly my entire breast, save the nipple, has fallen out of my robe. Steve's fork clatters onto his plate and he hands Callie to Tony and stands up.

"Dude, come on. Like you could atleast try, " Bruce groans, gesturing at the obvious erection before Steve has a chance to fix it.

He looks up at me from readjusting himself, his face twisted as if he's about to cry, "I'm sorry."

"No it's okay, I'll go change."

"Uncle sad?" Callie asks, her eyebrows dropping in concern.

"Uncle's willie gets excited when he sees boobies," Thor whispers.

"Thor shut up!" Cap hisses.

"What? She doesn't know what I'm talking about."

"Thor..." Tony warns.

"Willie?"

"His wiener... his penis." Thor looks up at Steve with a devilish grin and winks.

"Oh! I see?" Callie tries to squirm out of her Dad's lap but he holds her firm. So instead she reaches out a hand and his pants begin to slip down supernaturally, revealing the pink tip of his arousal. He manages to rip his sweats back up to his hips before she realizes what it is she's seeing, so we manage to avoid a terror-filled meltdown.

"Callie no! Bad girl, " Cap yells, his cheeks red and tears dripping down them.

Callie looks up at him, her lip quivering, then her face crumples, "Uncle yell at me!"

"No, baby don't cry, I'm sorry, " Steve steps forward, his face one of desperation.

"Wait, what the fuck happened? I'm confused again," Thor chuckles and Steve turns on him in a fury.

"This is your fault! You suck!" He barks, his voice verging on hysteria.

"Steve calm down," Tony says, trying to diffuse the situation.

"Uncle mad at Callie, " the baby sobs, heartbroken. "Uncle hate Callie, Callie bad girl."

"No, no baby, Uncle wasn't talking to you, " he moans, covering his face as he tries to get control of his emotions to no avail, "Tony help me!" He cries and looks desperately at the older man.

"Okay, come on, both of you." Stark sighs and picks up the baby. He wraps an arm around Steve and walks him out of the room. On his way out he looks back at Thor and says, "not cool."

Thor sighs and rubs his face, "fuck. I'm sorry."

"You didn't know, it's alright." I tell him and only half mean it.

"Callie flashed Nat at Steve like 3 times this morning," Bruce chuckles. "Because Uncle likes boobies and she was trying to do him a kindness."

"Oh, Jesus. I see, awe, I feel bad now." He groans. "I'll try to talk to him in a bit."

"Is something going on between you two?" I blurt out, I hadn't really meant to ask but Steve's outburst at Thor seemed unwarranted, but he's really not one to lash out at someone for no reason.

Thor's face blanches but he quickly recovers, "what?No, why?"

"He just seemed really angry at you."

"Well... I was being a jerk. And he's been really emotional lately, I shouldn't have been teasing." Thor shrugs, but he seems to be avoiding my eye contact which makes me suspicious.

"Right, I guess so." I chew my lip, searching his face for an answer but I don't find one. "Okay, I'm going to go get dressed now." I say slowly, and as I turn I see his face begin to fall.
