Black Widow

Black widow was investigating a new terrorist organziation called Neo-Hydra, they were creating weapons and selling them to criminals, Black Widow was tracking down one of the buyers when she got a message from Fury, the message was about a strange activity in a abandoned factory, Natasha decided to check it out, she drove to the location and found an old building, she went inside the building and searched for any suspicious activity, her instincts told her that the building was safe, she explored the building and found nothing, her instinct told her that the place was empty, her instincts were right, the building was empty, she checked the second floor and found nothing, but when she was leaving the building she heard a sound coming from the basement, it was like something made of metal broke with an impact, Natasha was curious and decided to investigate, she went downstairs and found the basement door was open, it was so dark that she needed to use a lantern to see anything there, she entered the basement and found several pipes through the walls most of them were rust but she could hear the sound of liquid flowing by them, as she walked through the basement she found one pipe that was broken in half but this was almost dry except by a drop of a black liquid falling from it, by the sound she thought that it was this pipe breaking but she didn't know why a drop of the black liquid was falling, maybe it was a leak or the pipe was leaking or it could be something else, Natasha didn't know, she just decided to keep walking but she didn't know that she was being watched, a Symbiote was observing her from the darkness, the symbiote followed her but it was hiding, it didn't attack her, it was just observing her, the Symbiote could sense that she was a danger to them and if it wasn't careful she could be a problem to the hive, the Symbiote had to be patient and wait for the perfect moment to strike.

Natasha was looking around when she heard a noise behind her, she pointed her gun but saw nothing, she didn't know what was causing the noise, maybe it was the building or it was something else, Natasha couldn't know, she just decided to keep going and find out, the Symbiote didn't want her to find out, the Symbiote was trying to sneak up on her, the Symbiote's plan was to disguise into her uniform and immobilize for the bonding process on a good place, the Symbiote waited for the right moment and jumped at her back, Natasha was distracted so the sudden push made her fell on her knees, she was confused and before she could look back, the Symbiote had already fused with her clothes, it was identical to her tight catsuit, she started looking around but there wasn't anything there, Natasha was confused and didn't understand what was going on, the Symbiote took a minute to fuse with her suit, it was trying to merge with her clothes and it succeeded, the Symbiote became one with her catsuit, Natasha was still looking for whatever pushed her, she didn't realize that her suit had become another creature, Natasha was a trained assassin but this time the Symbiote fooled her.

-Some minutes after-

Natasha left the abandoned building without any good results but she couldn't stop thinking about what pushed her, Natasha was a trained spy and her instincts were good, her instincts were telling her that something was wrong, but she couldn't find anything, the only thing that was odd was the black liquid that she found in the broken pipe, it was the only thing that was suspicious, she left this to solve on the other day, she just wanted to rest a bit, some hours later she went to the Avengers Mansion and laid on her bed, she didn't sleep very well, she couldn't sleep, her instincts were telling her that something was wrong, she started feeling like her suit was rubbing on her body, she didn't know what was causing this, Natasha tried to ignore the sensation but it was hard, her suit was tight and the fabric was rubbing on her skin, it was like her suit was alive and trying to get her attention, she felt a bit uncomfortable, she didn't understand why her suit was acting like that, she tried to ignore the sensation and focus on something else, she was thinking about what happened earlier, she couldn't sleep so she just stayed in bed and thought about what happened, the building was empty and the only thing she found was the black liquid, maybe that was the answer, she knew that she had already saw that before but she couldn't remember when, after a few seconds an idea came into her mind and it made sense.

"HOLY SHIT, IT'S A SYMBI..." she tried to say but her mouth was covered by several tendrils that emerged from her suit.

"Hello, Agent Romanoff, we have been waiting for this moment, our time together will be very exciting." A head emerged from her suit and started talking while her uniform started melting into the Symbiotic goo.

"MMMFHHH" she screamed and tried to move but she was restrained by the Symbiote's tendrils, her clothes were melted into the Symbiote's goo and her whole body was restrained by the Symbiotic tentacles, the Symbiote was exploring her body with the tendrils, she could feel the Symbiote's tendrils touching her skin, it felt weird but good, her senses were heightened and her mind was focused on the sensations, her body was restrained by the tendrils, she couldn't move or resist the Symbiote's invasion, the Symbiote's touch was sending shivers through her body, the Symbiotic suit that covered her body started to get tighter, tight enough to her pussy and nipples be visible through the suit, the Symbiote started exploring her tits, her tits were big and her nipples were hard, the Symbiote moved a tendril to her nipples and started teasing them, the Symbiote wrapped her tits and made her nipples stick out, the Symbiote's tentacles moved over her breasts and started touching her nipples, she could feel her nipples getting harder and the Symbiote's tentacle teasing them, the Symbiote didn't stop there, it send a large cock-shaped tentacle toward her pussy, the tentacle moved toward her pussy and touched her clit, the tentacle teased her clit and then moved to her pussy and pushed against her entrance, Natasha was still trying to resist, her mind was telling her that she shouldn't let the Symbiote to do what it wanted but her body was betraying her, her pussy was getting wet and the Symbiote could smell her arousal, the Symbiote was taking control over her body, the Symbiote sent another cock-shaped tendril to her ass, the Symbiote inserted the tendril in her ass, Natasha could feel the Symbiote's tentacle stretching her and entering her, the Symbiotic tentacles were stretching her, the Symbiote was violating her body and the worst part was that she was liking it, her body was reacting and the Symbiote was using this advantage to dominate her mind, the Symbiotic goo covered her mouth, her eyes, and nose, she could breath through her skin, she couldn't see or speak, her resistance was gone and her mind was slowly sinking in the pleasure, the Symbiotic cock in her ass was thrusting in and out, her pussy was dripping and the Symbiote sent a Symbiotic tentacle in her mouth, the Symbiote was **** her in all her holes, the Symbiote was thrusting his tentacles in her ass and pussy, her body was totally covered as a cocoon was made around her.

-Hours later-

the big cocoon on her bed started moving as a large claw emerged from the inside and cut it in half revelating her new uniform made of Symbiotes, her breasts were much bigger, her ass was sexier and her pussy was totally uncovered, her suit was almost like the classic she venom suit except by her face.
