Life of Winterwidow (Bucky and Natasha fanfic)

Old friends stay together (CACW continued)

Ironman found the base of all winter soldier prodigies, the old, abandoned warehouse full of experimented humans.
Captain America and The Winter Soldier lurked around every corner, worried what might attack them next. Steve crouched and snook down the rusty, decaying, metal steps and paused.
Tony pushed his way past the rigid iron doors across the room, startling the vigilantes.
Gun at the ready, Bucky crouched behind Steve, waiting for instruction. Steve lowered his shield to his hip and stood to face Tony.
"You seem a little defensive cap." mocked Ironman.
"Well," Steve paused, "it's been a long day."
Emerging from the shadows, Zemo lured all three men into the central room, the heart of all evil, the experiment room.
On a outdated computer, Zemo played the footage from December 19th 1991. Tony watched in horror,
"Hey," he called out, "I know this road!"
The three men all knew what the tape was.

Zipping down the dirty road, the old motorcycle pierced the silence with its roaring engine. The ray of light from the bike reflected in the ancient Mustang of Howard and Maria Stark. The Winter soldier intercepted with the car, causing it to hammer into the nearest tree. Gasps for air was all to be heard in the late hours of the night.
The soldier retrieved the package from the boot of the damaged Mustang and continued on to complete every part of his mission.
There must be no witnesses.
Targeting the male first, Bucky dragged Howard from behind the wheel and onto the dirty track. Pleading for mercy, Mr. stark was thrown against the side of the car. Punch by punch, the breaths of Howard because shorter until his final breath was released from his lungs. He was then placed back in the drivers seat, to replicate a car accident.
Maria was still alive but trembled with fear. The soldier strode to the passenger side of the car, her cry could be heard for miles. Gripping on tightly, Bucky squeezed and crushed Mrs. Stark's neck, restricting her oxygen intake.  A short moment later, she was the same as her husband. Dead.
Staggering past the car, the winter soldier slowly walked towards the CCTV camera, which was in operation while he performed the assassination. He retrieved his gun from behind his back, lifted his arm to point at the camera. One bullet was all it took to stop the recording and erase the evidence.

A single tear escaped Ironman's eye, he was heartbroken. However, all his upset and pain turned into anger as he plunged at The Soldier. Steve stopped Tony's actions before someone got hurt. Zemo grabbed his popcorn and watched in amusement as the friends battling to the death.
Blasts of repulsers and chiming of a shield deafened the surroundings, while causing pain upon each other.

Tony was targeted by both soldiers. As if it had been rehearsed, Bucky and Steve destroyed Ironman's confidence and will to fight on. But no white flag was raised.
Attempting to lift his head from beneath his shoulders, Tony had no luck beating the two men in a fight battle. Bucky repeatedly struck Tony in the temple. Steve vigorously hit his legs, shattering his knee; he fell to the floor. The shield flew in the air, then continued to attack Ironman violently. Each hit Bucky threw with the shield was more powerful than the last. Each exchange of punches became repetitive. The structured attacking sequence of The Winter Soldier triggered Bucky's killer instinct. While occupied by his own thought, Bucky watched as Ironman blasted captain America down onto the cold concrete.
With all his force and strength, Bucky rammed Ironman into the wall, throwing every punch with full aggression. Suddenly, Ironman's suit crushed at the heart, the armour began to shut down.
Red mist took over the soldiers eyes, murder was all he could smell. Tony's Arc Reactor sparked and flickered as Bucky tried to remove it from the centre of Tony's chest. With his final drop of hope, Tony targeted Bucky with his repulsers.
Bucky struggled to breathe, he struggled to fight, he struggled to even stand up. He leg arm was beside him, unattached from his body. A cry of pain escaped from Bucky's lungs, why had he let this happen to himself again?
Steve had finally recovered and charge at the exhausted Tony , they both crashed onto the strong, hard floor. Without thinking Steve smashed into Tony's face, he saw a glimpse of weakness in the eye of Tony Stark. Steve reached out for his shield and held it above his head. It came crashing down, Tony squeezed his eyes tight, frightened of what it was going to hit. To his relief, it stuck itself into the concrete beside him.
Tony lay there as Bucky streamed into Steve's shoulder , wishing for his arm back and wishing to see his family again. Both soldiers picked one another up and staggered back into the Quinjet, on their journey home, their journey to normality.
