Black Widow - Getting more than she asked for.

Natasha Romanova was walking through the inner corridors of S. H. I. E. L. D. helicarrier. The red haired S. H. I. E. L. D. agent walked silently wearing her tight black outfit. She was between missions and feeling restless.
So she was familiarizing herself with her environment. She turned a corner and found herself in an area for abandoned research. The walls were gray, smooth metal and all the doors had signs specifying what was stored there and a series of numbers. A high tech looking keypad and retina scanner was next to each door.
She noticed something odd. A small piece of what looked like paper was poking out from under one of the doors. The door was marked bio-research. She tried pulling it out but it was firmly stuck.
Suspecting foul-play she punched in her code and scanned her eye, unlocking the door.
The room was an old lab that seemed to have been mothballed some time ago.
The paper was an old receipt dated over three years ago when the lab had been abandoned, according to the inventory manifest on the clipboard just inside the door.
Realizing that no one had been in the lab since it was shut down and nothing was afoot. She decided to leave, then a blinking light caught her eye.
She pulled off the plastic cover to some kind of bio-tissue generator. It was a handheld device, sitting in a recharging socket.
She picked it up and examined it. Accidentally Holding it the wrong way, she pushed the blinking button.
A purple cone of light hit her over the chest. She dropped it as a warm feeling made it hard to breathe as a tightness across the chest increased.
Panic gripped her as she thought the device may have impaired her lungs and she might suffocated.
Then there was a ripping sound and she could breath easier.
She realized something was different when she felt the slightly cooler air on her breasts.
Looking down she saw her bust was larger than before. Formally a solid B-cup had transformed in to at least double D-cup.
At first she was terrified, thinking she would be a laughing stock of all the agents of S. H. I. E. L. D. and the Avengers.
Though as she thought about it, there was advantages to having set of plus sized gazongas. She thought about all the times she had seen men making a fool of themselves at the sight of a woman with big tits.
In fact it would be kind of fun to have all of the men fall all over themselves every time she walked into a room. It might even be kind of fun to make a scene. To walk in the ops-room or wherever the Avengers were hanging out. Go on a rant about dangerous equipment laying around and when she caught someone staring at her cleavage, she would get to chew him out. She could see herself giving Thor a piece of her mind about respecting Earth women or telling Captain America that in these modern days he couldn't act like some Forties throwback, ogling women.
And if Tony Stark made one of his snide remarks she could slap him over the face.
She looked down at her tits again, wondering if they would cause the stir she wanted. There was a few women on the helicarrier who had bigger boobs than this.
She paused for a moment and smiled.
Then she lifted the bio-tissue generator to her chest and pressed the button and held it for a good while.
The zipper split apart completely, all the way down to her belt. Only the top button at her neck held, as the top of her outfit gave way for her expanding jugs. They became the size of basketball's.
The fabric parted until it just barely covered her nipples. She activated her wrist-communicator and asked for the location of Tony Stark. Having received a location she strutted of swinging her hips and ass with a new found confidence.
She had been trying hard to keep an angry scowl on her face. But watching guards, engineers and other staff fall all over themselves at the sight of her massive jiggling rack made it hard.
She almost laughed out loud as she saw two guards walk straight in to a locked door. Having been distracted by her massive milkers.

She arrived at the doors were she was told Stark was. It read cafeteria, the doors slid apart and she stormed in taking a deep breath.
“What the hell is wrong with this........ Oh, fuck.” She started saying.

Meanwhile at ops.

Agent Maria Hill was sitting at the main security station watching various camera feeds from all over the carrier. She was tracking Natasha Romanova AKA Black Widow. She had newer trusted the woman. The former Russian spy had switched alliances before and could do it again.
She watched Black Widow walk in to an old bio-research lab on level six.
Her eyes bulged when she saw Black Widow accidentally enlarge her tits. She almost laughed at the sight of Black Widow's shocked face as her outfit ripped apart from her swelling tits.
Agent Hill thought that this might be one for the scrapbook, but then she saw Black Widow smile and turn the device on herself again, inflating her tits again.
Hill's jaw dropped at the sight of Black Widow's growing funbags. She was up to something, Agent Hill realized.
And when Black Widow made a request on her link she intercepted the call.
“This is Agent Natasha Romanova. Requesting the location of Tony Stark.” Said Black Widow.
“Please hold.” Agent Hill said. She flipped through the list displaying the location of everyone on board the helicarrier. Then she smiled as a funny thought formed in her head. “Proceed to the cafeteria to level three.”
The link clicked of. Agent Hill continued to watch Black Widow as she strutted through the carrier flaunting her tits at every man she came across. Until she entered the cafeteria. After Black Widow went in, Agent Hill accessed the door control and locked it digitally. Overriding the manual control, locking her in with a little surprise.

Rough and tumble at the cafeteria.

Hulk was prying apart a third vending-machine. He liked the tasty things inside, despite the thin tasteless stuff that kept getting stuck between his teeth and was wrapped around all of them for some reason.
He picked some of the plastic from his teeth and stuffed another five in his mouth.
Every one had left the cafeteria when he had started opening the machines. Which suited him fine as he liked his privacy as he ate or did anything.
He heard the doors slide open and grunted his annoyance. But as he turned to look at the intruder his mood lightened.
It was the red headed one. But something was different, something that made the raged remains of his pants feel tighter than ever.
“What the hell is wrong with this........ Oh, fuck.” Black Widow started. But stopped at the sight of the Hulk's leer.
“Big boobies!” Hulk said licking his lips.
Black Widow spun around and pushed the button to open the doors. But only got an electric buzzing denying of her request.
She rapidly stabbed her finger over and over on the button, but got nothing than an angry buzzing back. The doors remained firmly locked.
She could feel Hulk's shadow loom over her and she turned slowly around. Just in time to watch Hulk's cock rip his pants apart, sending the top button flying and hitting her between the eyes.
It was huge, ridiculously thick with an olive green head.
“Hey, big fellow. Lets not get over exited. This door won't open, could you....?” She said. Her eyes transfixed by Hulks huge throbbing member.
“Hulk make sex with red haired woman.” Hulk said, picking up Black Widow like a doll.
He lay her down on a table, on her back with a thud. Bending her legs back toward her chest. Reaching under her he ripped off a huge piece of her outfit. Making her ass hangout over the edge of the table, like a big round peach.
He put his huge cock against her pussy and pushed. She was tight and he was thick but her soft flesh gave way easy.

Black Widow tried to twist out of the Hulk's grip. But he was too powerful. She couldn't see what he was doing as her knees was pushing her tits up to her face, blocking her view.
But there was no doubt that there was a monster sized cock rammed to the hilt in her over stretched cunt.
He started slamming into her like a piledriver, making his balls slap her ass like two wrecking balls.
Over and over for what seemed like hours he fucked her. At first she thought he would fuck her to death. But he kept her just on the edge of what she could handle. The Hulk's power that had intimidated her at first was slowly becoming a comfort. He had all the power and all she could do was to lay there and take it.
As she surrendered the control she felt the first orgasm build. They came together in an exploding river of lightly gloving green cum.
The legs of the table gave way and they collapsed on the floor.
Hulk rolled off Black Widow and lay on his back resting. As soon as he closed his eyes, he felt something touch his cock.
Looking down he saw Black Widow trying to fit the head of his cock in her mouth, while she was rubbing his shaft with her huge tits. Soon he was hard again. She let go of his cock and turned around.
Standing on her hands and knees, she invited him to take her from behind. Looking over her shoulder she gave the green giant an encouraging smile and a wink while she gave a wiggle of her ass.
He was soon standing behind her guiding his cock to the little pink star that was her ass hole. Again going balls deep in the woman.
Black Widow hadn't expected the Hulk to fuck her in the ass. But she didn't resist, despite the pain.
She took the Hulk pounding her ass in stride. She made herself a vessel for the Hulk to pour all his frustrations into. Which, like his anger seemed to be endless.

A few days later.

Agent Hill was sitting at her private desk in her office. Looking at the bio-tissue generator, she had been zapping her tits lightly a few times a day. Unlike that bimbo Black Widow she was slowly growing her fun-bags. So it wouldn't be so obvious.
There was a knock on the door and Nick Fury walked in.
“Agent Hill, have you seen Agent Romanova lately or the Hulk?” he asked.
“I think Romanova is out on a mission, working a big member of some huge Mafia. Pumping him for information and you know the Hulk cum and goes as he wants. There is NO stopping him.” Agent Hill said, failing to hide her smile. Sliding the bio-tissue generator out of sight.
“And what the hell is making that sound? It's been going on for days.” Fury asked.
“What sound?” Hill asked.
“That thumping sound, Listen. I can hear it all over the carrier.” He said and they both listened. There was a distinct rhythmic thumping sound. Thump, thump, thump, thump, thump, thump.
Then it started picking up speed. Faster and faster until it suddenly stopped, followed by a faint grown.
Then after a moment it started over again.
“Oh, that. They are doing construction work in the cafeteria on level three. Remember I had you sign off on it a few days ago.” Agent Hill said, pointing to the paper work confidently.
“Right. Have them report to me when they return. I expect to be informed when one of my agents and one of the Avengers disappears on me.” Fury said and started walking out.
“It might be a few days, a week even.” Agent Hill said.

After Fury left Hill brought up the video feed from the cafeteria. It was always something different to be seen.
Some times Hulk would be fucking Black Widow in some new weird position, some times Black Widow would be desperately beating on the door begging to be let out and some times she would be Begging the Hulk for another rough fuck.

Looking at the video feed she saw Hulk fucking Black Widow who was laying spread eagle on the table.
Her huge tits flopping back and forth as Hulk plowed in to her. Looking closer at Black Widow, Hill saw that her huge dairy pillows had grown even more.
Hill wondered how it was possible. She opened a file on the bio-tissue generator and found out why the project was mothballed.
She saw images of a test subject who had an arm regrown by the device. The arm had continued growing at a reduced rate, with no end in sight. After a year they had to amputate the arm as the test subject had been unable to move around with it.
Hill looked down at her chest and realized her tits would grow ad infinitum and she knew in her heart she would let them.
In the distance she could hear the Hulk increase the pace, heading for another orgasm. She picked up the bio-tissue generator and aimed it at her tits. She smiled holding down the button and as her t-shirt burst apart she surrender to a future of having super huge tits.

The end.
