Part 1

–

After a few days, you had started to feel better and had much more energy than when you had originally gotten sick. Much to Natasha’s disagreement, you had gone back to work at the firm to take care of various meetings and deals. However, that was easily ignored because of how she was always made up once you came home and doted on her, giving her whatever she wanted.

A wet sensation on your face made you grimace and you groaned as you shifted on the sofa. Eventually, you came around blinking quickly to adjust to your surroundings and recognised a hefty weight on your chest. Once you glanced down, you were met with a faceful of wet puppy nose.

“Ugh, your breath stinks.”

Barney whined as you pushed his nose out of your face and he tried nudging you again, but you placed your hands on both his cheeks to keep him at bay. You groaned as he kept trying, stomping on your chest in the process, before you ended up shouting at Natasha to help you.

“Natty! Get your manky mutt out of my face!”

The sound of heels clicking across the laminate gave you a feeling of relief, knowing that Natasha was finally going to get her dog out of your face. With one last gentle shove, you were able to get Barney’s face out of yours, but he refused to move from your chest.

“Your dog has serious attachment issues,” you grumbled. Natasha scoffed slightly as she lifted Barney from your chest to cradle him in her arms like a baby, and you left out a sigh of relief now you could breathe properly. “He needs a bath as well, stinky mongrel.”

Natasha rolled her eyes at your dramatics and turned her attention to Barney, peppering his nose and head in gentle kisses as you stayed facing the ceiling, your forearm laid comfortably across your eyes. “He was trying to make you feel better, stop being such a grump, he loves his daddy as much as I do.”

“Very funny,” you mumbled in amusement. Natasha scoffed once more and kept her attention on Barney as she began to speak to him like a baby. “You were just trying to make grumpy feel better, weren’t you baby? Yes, you were, yes you were! Such a good boy, now go and play.” Natasha placed him down on the ground and smiled as he scurried off, but then pouted when your attention still wasn’t on her.

“Ahem.”

“Yes, my lo-”

Once you had turned your head to look at Natasha, it was as though all the oxygen had been sucked out of you, and you were pretty sure you had started to drool. The younger woman was dressed in a skintight, pink candy-striped nurse’s outfit which was short enough that you could see the curve of her ass as she gave you a twirl. To top it off, the outfit was complimented by white thigh-high stockings and dangerouslyhigh pink heels. 

 “Fuck me.”

“Is that an invitation, daddy?”

“Little dove, you look positively delicious, come here.”

Natasha stepped giddily towards you when you patted your lap. She was quick to straddle you and trapped you beneath her with her toned thighs, which you immediately ran your hands over, teasing to go under her skirt. The low cut of the outfit had her perked breasts sitting comfortably even if they were threatening to spill from the outfit. 

You tilted your head as you looked up at Natasha and bit down hard on your bottom lip, to help hide the smirk that had spread across your lips. Natasha took a shaky breath as she felt the hard package beneath her, which was comfortably tucked away in the comfort of your sweats, and you gave a sinister smile.

“You think you were the only one that had something planned? You should know I’m always one step ahead of you sweetheart, I always will be.” The lust that laced through your voice had Natasha squirming on top of you, and you let out a quiet groan as the piece of the strap nestled inside you brushed your walls. Nimble fingers made quick work of the tie of your sweats before they were desperately pulled down your legs. “So eager. I love it when you’re so desperate for me.”

“Please,” Natasha whimpered against your neck, gently sucking and nibbling across the column of your throat, knowing how much it riled you up. “I don’t think I can wait much longer, I need you to touch me so badly.” The end of her sentence was followed by a breathy moan as calloused hands roughly pulled down the top of her outfit and began to harshly grope her chest. 

“Oh-”

“Is this what you wanted, Little dove? You want daddy to use you however I want? Make you take whatever I give you?” Another whorish moan erupted from the back of Natasha’s throat as she rolled her hips more aggressively, the strap teasing itself through her slickened folds. Without prompt, Natasha moved one of your hands from her chest and towards her throat as she nodded in agreement.

“Use me, please. I won’t ask for anything else.”

“No?”

“I promise, daddy. Now fuck me.”

Ecstasy. Natasha was your personal strain of ecstasy and you were fully addicted. Your life revolved around the younger woman, and you could assume that you’d never get through a day without having at least one taste of her. 

“Whatever my perfect girl wants,” you agreed as you thrust your hips up, your strap easing into her quickly, and Natasha whined at the familiar stretch. Your starting pace was deep and brutal, Natasha’s breasts bouncing perfectly in time with each buck of your hips. It didn’t take long for you to pull the rest of Natasha’s outfit away, leaving her bare on top of you, free for you to admire. “You always take me so well, sweetheart. Your pretty pussy sucking me in, such a good girl.”

Natasha clawed at your stomach, covering it in aggressive red marks as she rolled her hips in time to match your unforgiving thrusts, and whimpered as the hand around her throat gradually tightened. Her jaw was slack, her hair draped loosely across her shoulders, and her eyes were clenched shut as you relentlessly pounded into her. The strap nestled inside you stroked your walls, hitting you in all the right places, making your legs tremble, but you refused to give in to the pleasure. 

“‘M so full…feels so good. Harder, please,” Natasha slurred as her movements started to become sloppy. A small slap to the face, and a tug of her hair, was all it took to get her movements and focus back on track, her bottom lip now held captive between her teeth. Once both of your rhythms were back in sync you made sure to give Natasha what she wanted, but that wasn’t before flipping the two of you over so she was laid on her back underneath you.

It was easier for you to discard your shirt, tossing it aside to the pile of clothes, and Natasha’s hands were quick to find your breasts. She squeezed your chest harshly, both of you moaning from the copious amount of arousal you were both receiving from each other’s actions. You grunted as you angled yourself differently, finding yourself able to push the strap deeper into both you and Natasha, and smiled as a broken moan made its way from Natasha’s mouth.

“That’s my girl, so desperate for my cock, aren’t you? Just a needy little whore,” you chastised confidently. The white of your knuckles beside Natasha’s head was the telling point that you were close, alongside the clench of your jaw. Natasha nodded in agreement as she pulled you down to kiss you fervently, her legs wrapping tightly around your waist to bring you closer. 

“Fuck, right there, don’t stop,” Natasha mumbled against your lips between desperate kisses. The kisses were open-mouthed, sloppy and uncoordinated, not to mention they were essentially just a clash of teeth and tongues. Both of you were desperate to get the other to finish first, but the desire for you to taste each other overruled.

“Not planning on it, sweetheart,” you replied quickly before you clashed your lips together once more. A hard spank to Natasha’s ass, followed by a few more, had her sucking your tongue into her mouth which drove you to thrust harder as you both neared your high. “Are you going to cum with me, pretty girl? Keep being good for me?”

“Yes yes yes! I swear, please let me cum- fuck!”

You moaned into Natasha’s neck as you felt her body tense underneath you, her thighs beginning to shake as she gripped onto you tighter. Removing one of your hands from above her, you snaked it down between your bodies and pressed your thumb against her clit before moving in circles. “You wanna cum? Cum for me baby.”

Natasha sobbed into the crook of your neck, her legs shaking violently around you as she finally fell over her peak, you following shortly after. You hummed in appreciation into Natasha’s neck as you slowed down your hips, beginning to mouth at her neck and collarbone to mark her.

“Ouch!” Natasha hissed as you bit down particularly hard on the column of her throat. You hummed against her throat and kissed down her body, still sucking marks into her milky skin, and moaned loudly as your mouth attached to her core. You slowly lapped at her entrance and clit teasing her relentlessly, moaning between each taste as you gripped her thighs tighter. “Mmph! Daddy, I can’t.”

“Come on princess, I know you can give me another one, but first I want you to do something for me,” you bargained, kissing along her thighs, and chuckled as she tried to wriggle away. The whines that came from beneath you sent a shiver down your spine, you loved how vocal Natasha always was. “You seem to have been a messy girl, and I want you to clean me up before I give you your special kisses.”

“C-Clean you up?”

The softness of Natasha’s thighs was enticing, and you couldn’t help but sink your teeth into the flesh of her inner thigh. Natasha’s back arched off of the sofa, her skin prickled with goosebumps, and you ran your tongue across the deep mark you just created to soothe it. You moved to lean back on your calves, predatorily staring down at her, and the strap was now back in Natasha’s sight.

“You’ve made such a mess of my cock, princess. I think you should come and clean me up, so I can give you what you want. That seems fair, doesn’t it?” 

A wave of arousal flowed through Natasha, straight to her already throbbing core, and she pressed her thighs together whilst she moved to kneel before you. The way you towered over her always made her feel so powerless, so submissive, and it was her favourite thing. Nodding quickly, Natasha reached for the wipes on the table; you were quick to correct her when you gripped her jaw and forced her to face you.

“Nuh-uh. I want to see what that pretty little mouth of yours does, considering you’re always running it. Now, get to work sweetheart, the quicker you make me cum the quicker you’ll get your reward.”

Natasha blinked quickly, processing your request, this must have been the first time you’d ever requested anything that could be deemed more for your pleasure than her own. It wasn’t hard for Natasha to come to terms with the fact you seemed to be a ‘touch me not top’, not that Natasha’s pillow princess side was complaining. Eagerly, Natasha moved to kneel on the hardwood floor beside the couch, as you sat more comfortably and lounged back into the comfort of the cushions.

“I wonder how bruised I can make your knees with how long I keep you down there,” you teased menacingly, a sadistic smile on your face. As a reflex to your filthy words, Natasha’s freshly manicured nails dug into your thighs, tight enough that crimson liquid was brought to the surface, and a pleasurable hiss left your mouth. “Fuck.” 

“Can I? Please?” Natasha questioned shyly, practically drooling at the sight in front of her. You watched as Natasha shuffled impatiently in her spot, her tongue darting out slowly to wet her lips as she drank you in. “I wanna touch you, daddy. Please let me.”

Before you could even finish nodding and giving permission, Natasha licked a long stripe up the toy and moaned at the taste of her own slick around it. Marvelling in her actions, you threaded your fingers through her thick locks, to keep her hair out of the way, as she took the whole length in her mouth until the tip of her nose brushed your pubic bone. “That’s it dove, you can do it. Such a good girl for me.”

A muffled agreement is heard as she keeps bobbing up and down to the attached appendage, slivers of spit spilling from the corners of her mouth. You bit your lip hard, groaning at the sensation you could feel through Natasha’s movements, and your hips bucked involuntarily. Natasha gagged with a whine, but that was quickly followed by a moan, and her eyes began to water. “So pretty when you cry…now, let me use that mouth of yours sweetheart. Sit up straight.”

You pulled Natasha off the strap by a fistful of hair, smiling cynically when you heard her gasp for breath and splutter, and gently stroked the side of her face. “Colour?” “Green, daddy.” You nodded, running your fingers through her hair to grab a fistful, and you hummed as Natasha automatically opened her mouth without any prompting, and stuck her tongue out. Leaning down, you let saliva gather in your mouth before letting it drop onto Natasha’s tongue.

“Don’t you swallow until I tell you to, you hear me?” You stared Natasha down, as she rubbed her thighs together to gain some sort of friction, and tilted her chin up towards the ceiling. You watched closely as the drop of spit travelled down her tongue. “Swallow, now.”

Without hesitation Natasha swallowed, making you smile, and then you leant down to capture her lips in a dominating and bruising kiss. The younger woman’s hands twitched with vigour, knowing better than to grab onto you, as she awaited your next move. Once you had suddenly pulled away, you wasted no time in pushing Natasha’s head down onto your cock, ultimately making her gag, and began fucking into her mouth. 

With every thrust you groaned with pleasure, creating a comfortable rhythm for yourself to receive the most pleasure, and for Natasha to not get really hurt as you used her however you wished. The stimulation of the strap, as well as Natasha’s nails scratching at your thighs quickly, had you close to the edge. “That’s my good fucking girl, so well behaved. I’m gonna cum, dove.”

The Russian looked up at you through her eyelashes, her mascara smudged from her tears, and you could see how fucked out her mouth seemed but you weren’t finished. Not yet, she was far too beautiful on her knees for you.

“You look so pretty with my cock in your mouth. I should have you on your knees more often,” you panted, Natasha’s doe eyes looking up at your own. You knew how much Natasha loved the praise, loved the validation, it was what had her so attached to you. Her whole life was you.

A few more thrusts were all it took for you to hit your peak, a string of ‘fucks’ mixed with praises of ‘good fucking girl’  for Natasha tumbled clumsily out of your mouth. Natasha pushed her head down the whole length of the strap and then pulled off with a ‘pop’, doing her best to catch her breath as she pressed open-mouthed kisses to your thighs and lower abdomen. The twitch in your legs had Natasha giggling to herself whilst you slowly lowered yourself to her height so you were knelt in front of her. 

“Holy fucking shit.”

Natasha giggled once more and leaned forward to pepper kisses on your face until you pulled her in for a proper kiss, your tongue gliding possessively across her bottom lip asking for entrance. She melted into your embrace pulling the strap away from your hips, causing you to whine slightly from being sensitive and tossed it to the side to clamber onto your lap. The way Natasha felt in your arms was something you would never get tired of feeling, your bare bodies pressed against each other.

“That good, huh?” Natasha teased when she pulled away, gently pressing a kiss to your nose. You rolled your eyes at her smugness but nodded in agreement, pulling her closer to your body to press kisses against her neck, and then chuckled as she started to shift in your lap. “Someone is eager to get some special kisses. Aren’t you, my love?”

“It’s been so long since I’ve had your mouth on me, I just…I need it so badly,” Natasha whimpered, bucking her hips towards you. It was easy for you to lift yourself off the ground, even with Natasha still comfortably sitting in your arms, and you made your way up the stairs to toss Natasha haphazardly onto the bed. “Watch it! I’m fragile.”

“Fragile?” You repeated a sarcastic smile on your face, “With the ways you want, and ask, to be fucked I wouldn’t exactly believe that you’re fragile. Now my little dove…I want you to lay back and put your pillow under your hips, you know the one.” Without hesitation, Natasha did as she was told, and you settled on your stomach and admired her glistening cunt with a proud smile. “This wet just from sucking on my cock? You’re such a messy baby.”

“Yes! I-I’m messy, and needy, and just- please.”

“When have I ever told you no, little dove? I’m sure as hell not going to start now,” you muttered lustfully. You made quick work of fully prying open Natasha’s legs and dived in like a woman starved. Your heavy, calloused, hands pushed Natasha’s hips down into the mattress when her back arched, and when her hips bucked upwards, to ensure that you had prime access to her puffy pink cunt. 

Sucking the sensitive nub into your mouth Natasha writhed beneath you, chanting your name like a mantra, and pulled at your hair causing you to groan into the tight muscle. The vibrations sent another wave of arousal through Natasha whilst she did her best to roll her hips against your face. The wet lapping noises echoed through the bedroom, highlighting the younger woman’s arousal, and you moaned as you pushed your tongue deeper into her folds.

“Can I cum? Please let me cum, daddy!”

You nodded against her and gave her pussy a sharp slap as she started to release, the taste of her dancing on your tongue, your moans harmonised through the room. Her trembling legs had you pulling her closer as you nuzzled your face further into her, and she loudly cried your name. The bottom of your face was covered in her arousal, before you slowly pulled away and kissed up her body leaving hickeys in your wake, not bothering to wipe your mouth.

“Are you okay, sweetheart?” you mumbled as you nuzzled your head into the crook of her neck, peppering soft kisses on her skin. The exhaustion washed over Natasha as soon as she came down from her high and she grumbled tiredly but nodded nonetheless. “Do you want a bath? Or just some cuddles?” “A bath if that’s okay? I feel sticky.” You nodded and slid off the bed, wrapping Natasha up in some blankets to keep her warm as you fixed up a bath for the two of you. 

Once you were happy with the bubbles and temperature, you left the bathroom to find a sleeping Natasha who was still curled up in the soft blanket. It was times like this when you always felt so grateful for what you now have, you had never felt as happy for someone to come into your life and turn it upside down until Natasha did. She was yours, and you were forever hers. Knelt down beside the bed, you gently started to stroke her cheek with your index finger and mumbled softly into her hairline.

“Sweetheart, I need you to wake up. We’ve still got to get a bath and it’ll end up getting cold.”

The muffled reply you received wasn’t really what you wanted, and was very hard to decipher as Natasha shoved her head further into your monstrous amount of plush pillows. Wandering hands found their way to her ass and you began to knead gently; one of Natasha’s favourite things was butt rubs especially if it led to a massage. What could you say? You were good with your hands. Natasha stirred to lay in your direction, peeking her head out of the bundles of blankets, and pouted lazily doing grabby hands at you.

“Carry me.”

“Yes, your highness. So demanding,” you mumbled teasingly, bringing the sleepy Natasha up into your arms. Immediately, the redhead found comfort in the crook of your neck, holding onto you as you placed her down in the warm bath; once the water enveloped her, a soft moan was released from the soreness in her muscles already easing and you climbed in behind her. The strokes you made against her skin as you washed her down were gentle, feather-like, and Natasha melted into your embrace. “Are you okay, little dove?”

“Mhm, jus’ sleepy,” Natasha whispered back, glancing up at your face with a soft smile. Her emerald eyes shone even more so than normal in the gentle candle-light, the steam from the hot water made her hair start to curl and you refused to take your eyes from her. You had seen a fair amount of women, but none of them could ever compare to Natasha. “Are you okay, daddy?”

The name brought you back to reality, recognising Natasha was very much in her subspace and you pressed gentle kisses to her cheek as you wrapped your arms tighter around her frame and pulled her into you. You smiled as she turned to face you, clinging onto you like a koala, and nuzzled her face deeper into the crook of your neck. “I’m more than okay, just thinking.”

“Think ‘bout what?”

You suppressed a chuckle at the slur and shortness of Natasha’s words, pressed another kiss to her head, and slowly stood up still carrying the redhead and wrapped her in her pink fluffy towel. “Don’t you worry your pretty little head about it, you just stay relaxed sweetheart and we can get you to sleep.” Natasha nodded and allowed you to get her dry and ready for bed, and you smiled gently brushing through her hair so that you could braid it, gently pressing a kiss to any spot that gets tugged because of a tangle. With some difficulty, due to Natahsa’s head drooping from being tired, you finally finished braiding her hair and climbed into bed to cuddle.

“Daddy?”

You looked down at Natasha who was laid on your chest, already staring up at you with innocent eyes, a small pout etched onto her face. “Yes, little dove. What’s the matter?” You spoke gently, your calloused hand moving to gently cup her cheek, and your brows furrowed with concern. “You know you can talk to me, even if it is me you’re upset with.”

“You know how I said I wouldn’t ask for anything else?”

“Mhm, what is it dove?”

“Can we get mcdonalds tomorrow?” Natasha whined in a sleepy voice, pouting up at you, and pulled the best puppy eyes known to man. It wasn’t a common occurrence for Natasha to want fast food, but how could you say no when she looked up at you like that? With a small chuckle you nodded, agreeing to the redhead wishes before you tried shushing her to sleep.

“Daddy…”

“Yes?”

“Just one more thing…” Natasha trailed off, looking at you with a cute smile, her lip tucked in between her teeth as she curled into your, tracing patterns against your bare chest. “Can Barney come up here for bed? Just for tonight, pleaseeeee.”

“Absolutely not,” you scoffed, a look of distaste on your features as you continued, “You know the rules, little dove. He’s not allowed into the bedroom or on the bed, we’ve talked about this before, Natty.”

Natasha’s eyes welled with tears at the rejection of her request, this being one of the only times you’ve ever said no to her, and your heart clenched in your chest at the sight of her non-pleasure related tears. It tore your heart more to have Natasha upset, than to have a dog in your bed, and you made the quick decision to hush her tears. “Fine, fine, fine. Please stop crying sweetheart. He can come up, okay? But it’s just for tonight, yeah?” you bargained, wiping her tears and kissing her nose.

Natasha nodded sleepily in agreement, pecking your lips multiple times in gratitude, and then smiled to herself. She knew you better than you knew yourself, even though you said one night, she was adamant that she’d be able to bargain for more. You made your way out of bed and downstairs to find Barney and came back upstairs with him wriggling in your arms, playfully nipping at your hands.

“Stay still, you little fuck.”

After you placed the pup on the bed, you laid beside Natasha once more to get your share of cuddles. Natasha smiled as she held onto you, letting Barney wiggle himself between the two of you and you huffed slightly. Turning your attention to the dog, who was trying to eat your hair, you gave him a warning. “I’m telling you now, it’s only going to be tonight you’re in here. You hear that you little punk? One night.”

Barney barked and you took that as the answer you were looking for. Once settled, you threw your arm over the duo, leaning down to Natasha to press your lips firmly to her own, and rested your foreheads together once you pulled away. “I love you so much, my gorgeous little dove.”

“I love you too daddy,” Natasha whispered, pressing one last kiss to your lips, tangling your legs together. You smiled, closing your eyes, bracing yourself for sleep to overcome you. Natasha giggled quietly to herself as Barney licked your cheek. “Barney says he loves his daddy too.” Natasha smiled more, listening to the sound of your heartbeat, and her gentle fingers traced soft patterns across your skin, easily sending you into a sleepy state. “I guess I love the little mutt too.” 

“Goodnight, daddy.”

“Goodnight, my little love.”
