The Naturalization Process [pt I]

Written in Collaboration with Namichwan

Claire hadn't been able to resist staring when she'd had complete control of her body. Now with all of her willpower focused on commanding her legs to resist stepping forward, she now enjoyed the unsettling experience of her eyes moving on their own to ogle every inch of Mark's genitals like they were the sexiest things she'd ever seen.

Which to be fair, despite a size that should have made him an object of bizarre ridicule, they were.

It was without doubt, the hottest dick she'd ever laid her eyes on.

Supported by a thick bulging corpus spongiosum that was, itself, of a size of the average man's entire penis, the girthy veiny muscular cock towered up from his lap to reach a point in line with his nipples. Claire's disobedient eyes followed the contours of Mark's cock, tracing every thick vein and ridge as it snaked upwards in front of his abdomen. The sheer size of it was staggering, and it was almost as if her brain couldn't comprehend the sheer girth and length of it all at once.

As she looked closer, she noticed the pronounced head, flared and pink, almost begging for her to touch it. And the skin was so smooth, stretched taut over the rock-hard shaft, that it looked almost like it had been sculpted from marble. Claire resisted the growing urge to reach out and touch it, to feel the weight and heft of it in her hand.

Despite her best efforts, her body was betraying her. Her nipples were somehow getting even harder and her pussy was flowing freely down her thighs, and she knew that she was powerless to resist the primal urge to touch him. The sight of his massive cock was overwhelming her, and she could feel her body trembling with anticipation as she struggled to maintain control.

Ironically it was the bastard's own impatience that saved her.

After only a minute which had felt much longer to Claire, he clearly got bored.

“Well no point letting this boner go to waste. Oh, Natasha!” He called out towards the still open front door of the apartment.

What walked through surprised Claire to no end (which subsequently let her body take two more steps towards Mark, halfway to him already.) Black Widow, the Avenger and ex-SHIELD agent, had just walked into Claire’s apartment completely naked. Claire wasn’t exactly a massive admirer of women, but to say Nat had a supermodel body would be a massive understatement. Her skin, face, and curves were all perfect, like they’d come straight out of a perverted comic book. The way her body jiggled as she walked towards Mark, the confidence she exuded just from being in the room… it was amazing to watch.

“Yes, master?” Nat asked, kneeling in front of him subserviently. Claire obviously realised that was probably the case but the brief fantasy of her kicking him in the dick still felt like it was dashed rather harshly.

“Let’s show Claire over there me splitting your derriere. I think her body will be mighty jealous of the moans your body lets out.” Mark’s evil grin landed on Claire’s eyes, and she had to fight to make her leg sit still. Her slightly submissive tendencies shining through her horny state, and the fact she’d always been attracted to men with power didn’t help either.

“Of course. I’ll moan as m-much as I can.”

Natasha Romanov was very good at keeping her emotions in check. She’d been trained from a young age to do so, very rarely ever showing anything but complete professionalism while on the job. When you were a human amongst gods and monsters it was important to never slip up, never give up on your morals, and always keep a calm head.

But she was so fucking excited to fuck Mark it hurt.

Years of her life had been dedicated to being kept at a torturously close, yet distant leash to him. She’d proven herself over and over again, helped him conquer, protected his life, strategised how to take down her friends in the most intimate and sickening ways. Yet the King had never fucked her. Not once. The closest she’d ever gotten was licking his dick mid-orgy, but then quickly bullied by Shuri into licking T’Challa’s dick instead. The carrot on the end of a stick, the one she’d originally convinced herself she never wanted out of pride for who she used to be, had eventually broken her spirit enough to consume her desires. So when she was given to this Mark, she feared it would be more of the same. He’d fuck America and Felicia and ignore her. He’d already decided to take on the whole building before her, as she waited behind him naked and licked his semen from pussies whenever he demanded. The scent staining the apartment affecting her just as much, making that innate desire of the Black Widow come straight to the surface. She wanted him more than breathing.

So Natasha crawling on top of Mark elicited a few responses from her. “Woah, you’re fucking wet down here!” Mark commented, seeing enough liquid across her glistening thighs to make him think she’d peed. And then, as he looked up, he saw another kind of liquid. “Wait, are you crying?”

It wasn’t a lot of tears, just a single stream down her left cheek as her stoic emotions battled her inside desires. Her pussy was pressed against the prick she’d wanted so long, and she couldn’t help but ask, “Sir… may I please kiss you?”

“Uh, oka-MPH!”

Natasha’s pussy dove down onto his prick while her face collided hard with his. To call it love would be a sick and twisted perversion of the word, but to her Natasha felt true love for Mark. Unrequited for so long, now all her fantasies were finally coming true. The huge head of his cock began to split her open, slowly, teasing her dripping slit as it stretched her wider and wider. Further than any man in Markanda ever had before. She was finally experiencing the true woman-making experience that so many had raved about for years.

And it was glorious.

Further and further Natasha’s shapely rear began to slink down Mark’s pole, stretching her sensitive walls around his epic length, like she was a brand new never-been-worn-before glove for his dick. It was sending electric shocks all throughout her body, sending the stoic Black Widow into full convulsions of pleasure the more her pussy ate.

Her upper mouth eagerly licking and sucking Mark’s own. He was just along for the ride at this point, keeping both hands mauling her ample buttocks while letting Nat dominate his face with her weirdly passionate love, He wasn’t exactly against the idea of having this hotty be so into him, initially Mark had thought she’d still hold onto some strange loyalty for his other self, but right now as his dick hit her cervix and her dripping moan seeped out of her mouth… she was proving quite the opposing viewpoint.

Meanwhile, five steps away, Claire’s fingers were betraying her.

Not only had she cleared another couple steps from hearing Natasha’s moans, now she had to split her concentration between having to mentally battle her feet and having to mentally battle her hands. She didn’t WANT to masturbate to this, but clearly her body had other thoughts. Managing to flick her clit and send zings of pleasure through her… that was making it hard to concentrate. This war between mind and body was fierce, and her body knew all of its own weak points to affect the mind’s abilities.

If her fingers weren’t flicking her bean, they were flicking her areola. Or her mouth tried to bite her lip seductively. Or her nose was inhaling large amounts of the horny airborne sex from the rutting pair in front of her. Or any number of other things that was making it so tricky not to go over there and kiss that man’s balls to take the edge off.

“Wow, when you pour it on, you really pour it on.” commented Mark when their kiss finally stopped. Natasha was just grinding herself into him, feeling the full size of him inside her lonesome pussy and moaning excessively. Her full pouty lips and blushing face was quite the arousing sight for Mark, and though Widow would usually use that to her advantage in a battle scenario… right now she couldn’t stop her body from orgasming right there in sheer dominated bliss. “Geez, you were wound a little tight, weren’t you?”

Her body practically melted into him. The great Black Widow became pure jelly as her bouncy curves lost their strength. “Mark… th-thank you…” She whimpered, pecking the side of his mouth weakly while his hands explored her shaking body. “Thank you…”

Mark just chuckled, “Other Mark was a little mean to you, wasn’t he?” He spoke down to her, but she didn’t mind. Nodding meekly before moaning as his hand went through her hair, “Don’t worry little Widow. You’re all mine now. I won’t ignore this fine booty, as long as you help me properly.”

“Of course.” She smiled, feeling more secure and loved in the Hidden Phoenix Leader’s arms than she’d ever felt in the Markandan King’s. Her eyes peered over her shoulder, returning to business as she eyed the struggling nurse. “Target about four steps away. Her mind has yet to fully give over but her body seems ****.”

“And what are you gonna do about it?”

In a shared moment of confidence, they exchanged a knowing smirk before Natasha took the lead.

“Put on a show.”

With a forceful motion, her ample derriere lifted off the couch before slamming down again, eliciting a guttural groan from her lips.

“Ahh~! Oh god MARK!” she cried out, her body gyrating with pleasure. “Your dick is the biggest! Your dick is the BEST! Ah~!” Natasha looked back to see Claire’s eyes locked with their sex, practically drooling over the dripping pussy being stretched to the limit. “You’ve finally shown me REAL! SEX! Masturbating, sex with SMALLER males, nothing else compaAARREES! This is TRUE! HAPPINESS!” Her hips were slamming down extra hard to emphasise her words, and soon her hypnotic booty had closed Claire’s gap to about one step away. Appealing to her body’s base instincts was proving to be too much for the poor nurse to handle.

Ass jiggles had been shown enough, it was time for some titty bounces. In a flash, Nat had rotated around to face Claire, showing off all her full russian glory to the puerto rican nurse. Her arms rose up and placed them on two parts of Mark’s head, encouraging him to cradle her breasts while he humped up from below. “Oohhh~ Even your hands know exactly what to do~” Natasha continued to coo, loving the way he groped his property so shamelessly.

Claire was intensely jealous. She wanted to be treated like a piece of meat. She wanted to have her cunt stretched over a chunky slab of white meat. She wanted to be dominated by a man who knew what he was doing in the sack. That jealousy was overtaking her. The mind of the nurse was starting to become convinced by the intense pleasures her body was begging for.

Another step was taken without Claire even realising. Then another. Then another.

She fell to her knees in front of the pair. Her body was **** enough to send her face rocketing towards the ballsack… but her mind caught her just in time. Inches from the prize.

“Oh, look at her struggle.” Widow tittered above her. “Trust me. Resisting only makes the fall even SWEETER!” She gasped out while her cervix was battered once again.

The smell was intoxicating, the heat was maddening, and the temptation was larger than it ever had been before for poor Claire. A tiny part of her wanted to hold on, to survive the hour and then figure out how to contact Luke, Jess, Matt, or even Frog Man at this point. But that part was losing focus. Not even able to hold dominion over her tongue that stretched ever closer to the balls, but failed to make contact.

They stayed like this for a good few minutes. Mark just enjoying the supple sensualities of fucking a Black Widow, while Claire’s war of attrition fought valiantly against her own body.

“P-p-please…” she heard her literal body beg, figuring out how to control her vocal chords through sheer **** of will. “p-pleeeaasseeee…!”

“Oh GOD!” Nat moaned over Claire’s begging, “MARK! I’M GONNNNAAAA AAIAIIIIIIIEEEEE!!!!”

The legendary SHIELD agent came hard against the thick dick inside of her. Spraying her juices out from her cunt to cover the nurse’s face with juice.

It was the final straw for Claire.

She lunged forward, uncaring and unleashed, jamming her face deep into Mark’s nuts as he continued to fuck Natasha through her clenching orgasm.
