An Avenger's Timetryst

"That is America's ass!"

Finally understanding why so many had lined up to fuck her Natasha shook her head in amazement. With a butt like that? In a tight black stealth suit?? It was literally a target on her back! No wonder she never saw it coming...

Climbing up onto the bed Natasha knelt behind her own posterior, mesmerised by its size and perfect symmetry; smooth round skin unblemished by the tattoos and scars she would later receive. Reaching down the redhead massaged that oh-so plump flesh, taking the time to really grope her own body and luxuriate in her buxom behind. Feeling tell-tale vibrations course through the girl's jiggling flesh she heard her past-self moan; powerless to do anything but revel in lustful sensation.

Peeling apart her cheeks Natasha stared in genuine wonder. There it was; the thing that had caused all her troubles over the years, the source of so much pain and pleasure. Staring down at her own pink pucker Natasha was enraptured by the fresh little hole; this was not the useless incontinent crater she waddled around with today. This was still the tight malleable little hole that could be used to turn both hero's and villains to the redhead's advantage.

Of course, this young Natasha had no idea that her anus was the real source of her power; This Natasha still resented her behind and the humiliation it could bring whilst still allowing Maria to use her as she saw fit. Only Wanda had shown her that anal could be used for real loving connection and ultimately proving to the redhead that submission could be the release that she had so desperately needed. And now Future-Natasha could give herself that gift:

Sucking her finger, Natasha made sure the digit was nice and slobbery before bringing her hand down towards that perfect ass:

Still tied upright in place the younger redhead moaned pitifully, her body lax from hours atop the Sybian, once taught muscles now soft putty, powerless to resist the anonymous finger.

Aware of her past stubbornness Future-Natasha elected to use another proven technique to quell her own anxiety. Pressing up behind her younger self, she gently rubbed the redhead's bare belly to comfort her frayed nerves whilst getting a nice second-hand buzz from the sybian between them.

Surprised by this gentle treatment from the woman she thought to be Maria Hill or one of her cruel lackeys, Past-Natasha allowed herself to be lulled by the soothing circular motion. Soon the redhead uncoiled, Future-Natasha watching with bated breath as her past-self relaxed into her grip; relinquishing control of her beautiful body; tensed cheeks separating to reveal the prize in-between.

Slipping her wet finger into the redhead's crack, Future-Natasha cooed into her own ear as she massaged that perfect pucker. Curling the probing digit into her ass both Natasha's moaned as she delved inside, gently stretching her tight little opening in preparation for further sodomy.

Past-Natasha whimpered in surprise, mouth hanging open, eyelashes fluttering as her butthole was massaged; this gentle treatment was so unlike the anal thrashing Maria had given her the day before. Shocked by this revelation, nonetheless the self-serious former assassin was still repressed and still afraid of what this submissive pleasure could mean to her.

Future-Natasha was amazed by the tightness of the girl's rectum; soft velvety insides gripping her index fingers in-spite of Maria's previous break-in and her current gentle treatment. Was she always this uptight? Clearly the Avenger would have to go deeper if she were going to reset her past-self's anal attitude and bring her around to the salacious joys of sodomy. And so the maturer redhead began wiggling, scissoring and pistoning her forefingers to achieve this desired effect.

Wriggling against the buzzing machine between her thighs Past-Natasha panted; her rational mind long since eroded by Maria's sexual torment. Lost in a deplorable haze the beautiful doppelgänger squeezed her eyes shut, refusing to give in to the pleasant sensations that racked through her ass. Natasha Romanoff could not become some anal loving whore; she was a Black Widow!

Unknown to her Future-Natasha was merciful; intending to show her past-self the true glorious ecstasy. Pressing a third finger between those perfect cheeks she gauged her own reaction carefully; the younger redhead's legs shaking as her tight body spasmed, velvety sphincter pulsing in response to Natasha's kind but firm digits. Absorbing every twitch Future-Natasha purred, becoming increasingly aroused by her own pleasure: the two identical women intertwined across space and time.

In spite of being immobile and tied upright the past-agent was aware she was close to complete emotional exhaustion; all too willing to receive even this taboo kindness after hours of unsatisfied lust. Lulling in her restraints she let curly red hair fall over her masked face; glad that her vision was obscured from the mirror opposite that would demonstrate her slutty submissive.

Fingers coming free with a soft wet pop Past-Natasha moaned, behind wriggling impotently as she sub-consciously begged for more.

Flexing her hips backward, Future-Natasha withdrew, allowing her utility belt to buzz into life. Nanobots forming into a large red phallus, the redhead shifted forwards once more, preparing her past self for an anal experience that would change the girl forever. Believing she knew what was coming, Past- Natasha braced within her restraints; strengthening her posture for a brutal butt bombardment that never came.

Feeling the distressing sensation of an impossibly large cock being pressed between her pearly white cheeks, the restrained redhead moaned as she felt the erect shaft part her plump flesh once more.

Unbeknownst to Past-Natasha, the futuristic phallus was essentially self-lubricating, it nanotech surface allowing the shaft to slide effortlessly against skin. Fibres rippling between the girl's fat cheeks, the cock that had so recently been within Wanda's fresh pussy would soon be slicing through Past-Natasha's backside like a hot knife through butter.

Teasing the delusional SHIELD agent Natasha kept herself calm in-spite of the incredible prospect of being able to take what had always been denied to her; the Black Widow's ass! Enjoying this delicious irony, the redhead whispered in the girl's ear:

"Come now Dreykov's daughter; you can lie to yourself but you can't lie to me. After all, I am you... I know you crave submission, to be free of the immense responsibility, the guilt of all your crimes."

Running a finger along the girl's sweaty back she held the redhead close: "Let go of your shame and embrace it!!"

The head of the flexing dildo still wedged between her past incarnation's cheeks, Future-Natasha shifted the angle; allowing the end to brush up against that soft pink crinkle. Blowing sweaty red hair away from her face, the stubborn young Avenger yelped pitifully:

"Ugh! Just do it! Please-ugh!"

Future-Natasha grinned:

"Your wish is my command!"

Pressing forward with her hips the redhead felt that oh-so tight puckered opening spread around the head of her synthetic cock as it finally sliced inward; penetrating Past-Natasha's spoilt ass:

"Ughhhh!"

Groaning wantonly, Past-Natasha's mouth echoed her asshole as it was slowly and inevitably invaded from behind; the thick head driving into her vulnerable flesh to stretch the girl open. Asshole giving in to this unyielding pressure both Natasha's sighed as the rigid pole entered the young redhead's butt; Future-Natasha experiencing her sodomy through a paradoxical symbiotic osmosis.

The young SHIELD agent choked for breath as the shaft slowly slid through her tight back door and into those forbidden depths. Squirming against the sybian, Past-Natasha focused on the constant pleasure in her nethers rather than the pain in her ass as she was slowly and inevitably skewered.

Future-Natasha knew all too well this part was painful, having literally been in the same position the young redhead was in now. But Past-Natasha wanted this, even if she couldn't admit it.

Burdened with this knowledge Future-Natasha forcefully rolled her hips, wriggling the cock deeper and deeper into her own upturned ass. Inch after inch disappearing, eventually her thighs slapped against Past-Natasha's fleshy buttocks. Finally stuffed, both redheads let out a guttural groan as they got up to the hilt of the dildo; a massive member buried between the two of them.

Reflecting on her latest submission Past-Natasha whined; so the first time hadn't been a fluke, so she was destined to repeat this anal mistake over and over again. Did that make her just another of Hill's Sexual Espionage sluts? Or could this be something more?? Faced with an insane dilemma the young redhead considered something impossible: What if anal wasn't a mistake?!

Feeling her younger self twist back against the cock Future-Natasha rallied; if the girl could truly embrace these pleasurable sensations the young Avenger could reach a massive breakthrough, perhaps even overcome the hold Maria had on her! Inches of synthetic cock now filling her sore rectum however, Future-Natasha knew she would have to help, cradling the girl whilst twisting her hips to allow the huge shaft to gently stretch her bowels rather than mashing them to a pulp as Maria so often did.

Mystified by this gentle stirring the young redhead felt her internal muscles contract momentarily against the unyielding wedge before mercifully relaxing on to it, this rectal acceptance sending a glorious tingle up through her belly:

"Ohhhh wow..."

Wearing Past-Natasha's anus like a well-fitted glove, Future-Natasha tightened her grip on trembling thighs and began to slowly pull her strap-on from the redhead's soft butt. Crying out as it came free, Past-Natasha realised in amazement that she wanted to be filled once more.

Knowing she should feel grateful for this anal relief, Past-Natasha moaned wantonly; why instead did she now feel so... empty??

Stroking her doppelgängers red hair Future-Natasha cooed sadly: "All that 'resistance' and you still miss it when its gone..."

Faced with the unfaceable the girl sobbed:

"I-I don't understand??"

"Its really not that complicated," Natasha explained: "Don't deny it, embrace it! Feel the pain, the embarrassment, the submissive joy. But don't let those feelings define you! Just embrace them!"

Rolling her hips, the future incarnation sliced her cock back into her vulnerable young ass, eliciting a grateful groan from her past-self:

"UNNNGH!"

"Yesss! Ugh! Embrace it!"

Gripping her hard, Past-Natasha hissed as the mysterious woman invaded her butt once more. No longer resisting however, the truth burst through the redhead before she could even comprehend it as she was anally fulfilled:

"Urrrgh! I-I want this! Ohhh-god I love it-Nngrrrhhh! God I love it sooo much!!"

Feeling that wave of joyous self-recognition; both Natasha's screamed in ecstacy. Reaching the conclusion Future-Natasha had taken 10 years to recognise let alone say, the redhead gave up her foolish pride for anal acceptance; replacing frustrating repression with pure lustful joy:

"UNNNGHHH!!! YESSS!!!"

Moving in perfect synchronicity both Natasha's rallied, their bodies meeting in the middle to fuck that magnificent round ass. Beginning a glorious rhythm; both Natasha's rolled her hips back and forth, creating a perfect anal mechanism that sent the cock sinuously back and forth to turn Natasha's insides into a playground of pleasurable anal sensation.

Melting together both Natasha's gave in to the inevitable onslaught of joy:

"You're not afraid of anal -Ugh!!"

Future Natasha yelled over the redhead's groans and moans:

"Ugh! You're scared of how much you love it!! -Uggh!! And one day you'll have been fucked so much you'll be known throughout the world as the ultimate anal whore!!! UGGHH!! And this tight little hole will gape so wide you spend half your time in diapers!!! UNNGGHHH!!! And you know what?!?! You'll only -Ugh! Want it -Ugh!! MORE!!!"

For the future Avenger this admission was the catharsis she so desperately needed. Adrenaline rising in the time-traveller's chest Natasha let it all go, both redhead's combining athletic luxurious strokes that only a Black Widow's body could achieve, working together to thoroughly fuck that magnificent round ass.

Overwhelmed to experience this sense of utter anal joy one more time, Future-Natasha cried with joy: finally reversing her role to literally dominate her past demons. Coming to peace with her anal-loving antics after years of salacious depravity, the 'Black Widow' made sure to show her past self what a skilled but kind sodomiser could really do:

Both redhead's moaning deeply, the vibrations from the sybian beneath meant nothing now when compared to their anal ecstacy. Past-Natasha close to a major meltdown Future-Natasha was very close behind, both Past and Future feeling every stroke of her cock as it delved deep into her ass again and again and again.

Going over the edge of delirium, Past-Natasha threw her head from side-to-side, red hair flying as she shuddered in the older woman's arms. Blindfold falling around her neck, the girl's sweaty brow creased and her eyes rolled back in her head as the mystery woman was revealed in the reflection of a mirror. Seeing double, by now such a revelation was meaningless to the sex-crazed girl, Natasha simply concentrating on feeding the dildo into her hungry rear like her life depended on it.

Lurid pleasure turning both women's sophisticated brains to mush they lost themselves; two bodies becoming one. Swaying from side to side past and present melded together in an act of paradoxical self-sodomy. For several minutes the Black Widow transcended all degradation and pain to achieve anal nirvana:

"This is it Natasha! Ahhh! This is who we really are-Arrrghh!! Black Widow: Anal Avenger!!!!"

Screams of utter joy filling the tiny cabin it was impossible to tell where one Natasha ended and the other began, past and future tangling into a heap of shuddering limbs and anal joy; their combined butt thrusting now as natural as breathing.

Tremors racking their identical bodies past and future Natasha came hard, their destiny's intertwined in glorious anal sex. Before either could even comprehend what had happened the redheads experienced another joint orgasm, spasming in place as fireworks burst through their systems; the Black Widow butt-fucking herself to multiple wonderful climaxes.

Gyrating together for an impossibly long time, eventually the two women simply couldn't keep going anymore. Clinging together they came to a shuddering stop; the fully fucked Avengers left hanging from the ropes above the bed.

Minds finally separating once more Natasha held the young redhead close, breathing in the girl's orgasmic self-acceptance. Reaching down between her ensnared thighs Natasha disengaged the throbbing sybian, Past-Natasha whimpering gratefully as she was set loose from the tormenting tool. Peeling herself away, the massive dildo slurped free of the girl's crack. Instead of revelling in it destruction as so many others had Future-Natasha massaged the redhead's red ring, eliciting grateful sobs from her young counterpart as she brought her back down to earth.

Easing the barely- conscious girl out of her restraints Past-Natasha was finally set free from Maria's prison, flopping backwards into her future's welcoming embrace. Carefully draping the thoroughly fucked young SHIELD agent over the bed the older Natasha climbed down.

Murmuring Past-Natasha sprawled over Maria's messy sheets in a satisfied heap; happy and fulfilled by all she had learnt from herself.

Re-materialising her nano-fibre suit, Future-Natasha' cock simultaneously retreated into the heavy belt around her waist. Exhaling deeply the time traveller squeezed back into the tight red and white uniform, preparing her GPS for quantum travel before she paused:

Glancing down at her past self once more, Natasha saw the redhead staring blearily back at her; the two almost identical women making eye contact for the first time.

Kneeling beside the young agent, Natasha stroked red locks from the girl's face, whispering to herself:

"What happens next is up to you; your future isn't set. Just know your ass is going to save the Universe!"

Leaning over the resting redhead, past and future met once more as Natasha kissed the Black Widow's cheek:

"And I forgive you."

Standing up from the bed Natasha finally sealed her suit, visor flipping down over the Avenger's head. Disappearing in a shocking flash, moments later the door slid open; Maria Hill stepping into the cabin to greet the unburdened woman in her bed:

"There you are!"

Clapping her hands the conniving brunette smiled. Affronted to find Natasha free of her bonds, Maria's expression turned cold. Scowling, the SHIELD Director calculated the situation; completely oblivious to the changed Black Widow before her:

"So... Now what??"

...

Watching the Avenger thunder back to the future Nebula de-powered the Quantum tunnel as Natasha flipped back her mask. Meeting the redhead's eyes immediately Nebula could sense the change; this Black Widow exuding a genuine calm and acceptance that had not been there before:

"Did you get what you needed??"

Stepping down from the pad Natasha took a seat on its rim, nodding wordlessly to the blue alien woman. Facing toward the huge glass windows, beyond the redhead could see the sky begin to turn; darkness giving way to the light of the sunrise.

"You know... you don't have to come with us today."

Turning back to Nebula the redhead raised an eyebrow, prompting the alien woman to continue:

"I'm just saying, saving the universe is above a normal human's pay grade: let the superior beings handle it!"

Natasha simply shook her head.

"What about Captain Marvel?" Nebula argued; "She is practically invincible! Better equipped for-"

"-A suicide mission?" Natasha responded dryly: "From what you've told me Vormir doesn't require strength; it requires sacrifice."

Shaking her head, the exasperated alien woman growled: "Then why not save your own ass??"

Leaning against the platform Natasha rested her well-used behind:

"Because this 'ass' is going to save the universe..."

"...whatever it takes."
