An Avenger's Fantasy

Satisfied Peggy pulled away, twisting her hips back and forth as if taking a warm-up:

"Here we go..."

"Unnnnghhhh!!"

Sharon shuddered as the hard head of a fat strap-on met her tiny little anus. Where had it come from? Just like her resurrected Aunt the strap-on's magical apparition was a mystery.

"Mmmmm... Oh woah!" Feeling her legs start to tremble the blonde clutched her sheets.

Lining up her bacolite phallus, Peggy ignored the whining child beneath her, closing one eye as she lined up her shot. Thrusting her hips forward, her hand guided the missile onto its target; penetrating her Niece's anus.

"Bullseye!!"

"Oh God Oh, OHHH!" Sharon blurted out, eyes becoming impossibly wide as her butthole was pulverised.

"Language!" Peggy tutted shamelessly, slapping a trembling cheek.

Laid out on her side Sharon struggled, kicking out instinctively as she was skewered. Wanting to find a more comfortable position but unable to go anywhere, the blonde twisted against the bed, legs cycling uselessly as she was inevitably filled:

"Unghh, ahhh..."

"Oh heavens above you are tight!" Peggy exclaimed breathlessly, genuinely impressed by her Niece's internal resistance; enjoying the physical challenge of overcoming this final barrier:

"Don't fight it sweetheart!"

"Ah but it hurts!"

Sharon's warning was tight, stressed, and ultimately ignored. While the brunette was moving very slowly, it still hurt, her Aunt's prick as hard and unyielding as the woman herself. While physically it was more discomfort than anything else, mentally, the blonde was in shambles. She was an Agent of SHIELD, of the CIA. A Carter! Faced against politics or even terrorists she was unflappable. But one night with her superior Aunt and Sharon was nothing but a bottom; forever impaled on the ultimate symbol of submission.

"A little more..." Peggy murmured distractedly, enjoying the moment as she shoved the fat shaft even further into the slender blonde's heaving frame, holding her firmly in place:

"Almost there Darling..."

"Unnnghh!" Gasping Sharon concentrated desperately on her breathing as she was shafted; this felt very real.

Relishing in her replacement's discomfort the brunette twisted the shaft, impaling the faux-Carter centimetre by centimetre:

Finally feeling her Aunt's hips slap against her behind, Sharon spluttered in disbelief:

"Oh my God!"

Savouring the moment, Peggy petted the girl beneath her condescendingly, making sure to ruffle Sharon's ruined hair. Enjoying the sight of her thick phallus stretching out her lithe young Niece, Peggy made sure to revolved her hips, grinning as the girl whined pathetically:

"Welcome to the Sexual Espionage Program little miss Carter."

Dedicated to her work Peggy slowly gyrated her hips, making sure to prepare Sharon by widening the girl's hole before reversing her movement. Feeling the pressure lift the blonde gasped in relief, her newly stretched out bowel desperate for relief from the bulbous head.

"Ohhh-Ugh!"

Pleasured gasped twisting into a tortured moan, Sharon's eyes shimmered as her Aunt thrust back in to her, splitting the blonde's cheeks once more. Shunted against the bed, Sharon shamefully surrendered her ass to a cruel impalement.

Now totally under Peggy's thumb, the brunette reveled in her victory, thrilled that she could literally fuck the hypocritical ideology out of the blonde, her kindness soon dissipating to reveal the cruel girl underneath:

Enjoying herself immensely the brunette cackled in delight: "Now who's a used-up SHIELD slut?!"

"What?!" Sharon croaked in alarm, the hard plastic load burrowing even deeper into her bowels.

"Unofficially of course," Peggy explained, pulling the dildo out of the blonde's behind, "But now my Darling you are just like the rest of us!"

Unable to respond in words, Sharon cried out as her Aunt plunged forward yet again, the head of her cock skewering the blonde's bowels, each thrust punctuating her words:

"How does it feel Darling?! Ugh! To be my new favourite?!"

Humbled, Sharon felt herself tearing up, her Aunt tugging on her svelte hips and throwing her weight behind the phallus:

"Like its-Ugh! Too good to be true!!"

Shifting backward the brunette smiled, preparing for her next dive:

"That is the nature of a good buggery! Ugh! The boundary between pain! Ugh! And pleasure! UGH! Fantasy! UGH! And Reality!!"

Plowing forward, Peggy watched gleefully as her dick disappeared into the former CIA agent's bottom: the blonde howling as her uptight ass lost its precious verve, each thrust stretching the girl wide open.

Whatever comeback Sharon had died in her throat; raising her voice above a husky whisper now taking more energy than she had to give. Attempting to squeeze back against the intruder, Sharon instantly regretted it; hot cramps shooting up through her belly.

'Phrrrppp!'

On the next thrust the blonde farted adorably, Peggy grinning at her Niece's abject humiliation. Repeating her movement, each swivel of the brunette's hips was accompanied by a small rush of air.

Legs kicking at her sheets, with each hard pump another adorable little squeak came out of Sharon's ruined behind, the blonde unable to stop herself as her insides turned to jello.

Peggy moaned, her only objective now to cum whilst stuffing her Niece's spoilt little ass: So much for the fresh young Carter, once she was done with this plonker Sharon would wish she'd let Natasha finish the job! Placing one hand on the mattress the brunette held firm, the big bacolite phallus only slipping deeper and deeper into Sharon's ruined bowels.

Confused and disorientated Sharon didn't know where her ass ended and the dildo began, desperate for a climax to alleviate the pain but even more desperate to please the woman behind her.

Unable to comprehend the totality of her submission, Sharon shrieked as her Peggy twisted the phallus deep into her guts, twisting and turning those curvaceous hips to bypass every internal barrier:

"Aunt Peggy please! AWWW!" voice becoming fainter, Sharon went limp, her body giving in to the brunette's relentless thrusting:

Rage overcoming her illusion, the brunette spat venom:

"Please? You want more after you tried to steal the love of my life?!"

Holding Sharon down Peggy drove another hard inch into the girl's slender butt:

"If you knew how much she means to me-"

Peggy blinked, facade momentarily slipping.

"I-I mean he! Of course I mean Captain America... As if you could have ever replaced me?! The inferior Sharon Carter!"

"Ohhh!" Groaning, Sharon screwed her eyes shut. The blonde was shaking, her muscles taught, coated in a fine, shimmering sweat:

"What is happening to me?!?"

Peggy shunted forward more determinedly, hands gripping the blonde's bare hips in an effort to drive the cock impossibly deeper. Both Carters gasped, Peggy in joy, Sharon in horror, as the brunette's thighs slapped against the blonde's bare cheeks again and again; flesh jiggling under the force of the brunette's disciplined strikes:

"What is happening? Ugh! Your world has changed and you can never go back! Ugh! All you can do is start over! Ugh! And over! Ugh! And Over!! UGH! AND OVER-RRR!!"

Thrown forward by each thrust, Peggy grabbed the girl's flailing hips, dragging the blonde back down in time to meet her pistoning cock.

Sharon gaped; lost between humiliation and immense satisfaction; grunting as her slender body was pushed far beyond its limits, the fat cock churning inside her ass, her Aunt's crotch mashing against her tenderised butt cheeks. Somehow, after everything she had lost her Aunt had found her once more; fulfilling her deepest and most twisted desires in a glorious fantasy!

And yet with each passing moment all Sharon could do was accept this as her new reality; accept she was the lesser Carter, accept that her Aunt had come back from the grave to show this to her true submission and due to a magical combination of pain, pleasure and exhaustion, she no longer even cared. On the next thrust the former Spy spluttered, full on yelling as her sphincter was permanently pulverized!

"Oh my God Yes! Fuck me Aunt Peggy! If this is my fantasy then don't hold back! YEsss! Fuck me! Ugh!! Fuck my Ass over and OVER!!"

Taken aback, the brunette watched the delusional blonde as she achieved her inception: taking deeper devastating strokes and jackhammering into the girl, Peggy literally destroying her from the inside out.

The pleasurable pounding reduced Sharon to a mewling husk, her mind melteing away further with every powerful thrust. As for the brunette, the empowerment to her ego and the shake of Sharon's hips were beyond delicious, Peggy above all loving the visceral feeling of her thighs smacking hard against the blonde's horizontal butt cheeks, the angle allowing her to access nooks and crannys deep inside.

All concern for Sharon's wellbeing long since jettisoned the brunette began moving at full tilt; her hips savagely slamming into the girl's increasingly red cheeks, the SSR Agent using every ounce of her strength to wreck her inferior replacement. Still laid out on the bed, the only thing Sharon could do was absorb the dildo's thrusts, gurgling in pained-pleasure, her ass impaled upon the large probe again and again and again; two pairs of identical brown eyes rolling back as both women screamed.

Sharon wasn't sure if she orgasmed, it was hard to tell; her body flushed with endorphins, belly tied up in knots as her Aunt rearranged her insides. Writhing on her side the blonde felt cream spray out from between her legs, a copious amount of hot sticky cum dripping down her thigh and onto the mattress.

Time and space losing all meaning Sharon was unable to comprehend the incredible feeling of giving up all that she had known; her dominant understanding replaced with a new submissive reality. Soon the whole room began to spin. Feeling a puddle form beneath her on the bed, all Sharon could do was mewl as she was slowly rewritten, every pre-conceived of notion control reversed as she was fucked into oblivion.

Broken and dazed the blonde collapsed; ultimately accepting this humiliating fate. Aunt Peggy continuing on relentlessly Sharon's mind turned to soup as the impossible fantasy faded into darkness.

...

Waking with a jolt, Sharon's eyes cracked open.

Sprawled out under her messy sheets the exhausted blonde hauled herself upright, scanning the room for any signs of her devious Aunt.

Morning light streaming into her small apartment the confused former agent found herself alone.

Falling back against her pillows Sharon rubbed her eyes, embarrassed by her strange lurid thoughts. At least it had only been a fantasy; imagine if she had really been fucked by her own Aunt!

Feeling a sudden cramp Sharon whimpered, rubbing her sore belly. Another gurgle upsetting her insides the blonde stumbled out of bed.

Moving toward the bathroom Sharon clutched her abdomen, her asshole throbbing, her gait strangely wide as she awkwardly crossed the carpet; oblivious to the missing files that had been strewn across her floor.

Flicking on the light switch Sharon saw her face in the bathroom mirror, surprised to find her skin sticky to the touch. That dream must have really made her sweat!

Leaning over the sink the blonde splashed her face before another deep cramp made her wince low over the porcelain. Clutching her abdomen the blonde bit her lip. Suddenly desperate Sharon rushed to the toilet, dropping her knickers before pressing her sore cheeks to the cold seat.

Closing tired eyes Sharon rubbed her forehead, trying to remember why she had been so worked up. Whatever scheme she had been formulating to get her career back on track the idea was entirely lost to her now. Eyelids cracking open Sharon sighed as she finally released her pent up internal frustration; formerly brown iris' glowing a lustful red:

Sharon's fantasy had become reality.
