Peter and MJ apartment

Mary Jane was alone in her house, Peter was on the heli-carrier so MJ still had some hours alone, MJ was watching a movie, a scary one, so she was afraid of a jump scare, MJ was watching a normal scene of the movie until the jump scare happen and she screamed, when the jump scare ended MJ heard a noise, looking around, nothing, she thought that it was just her imagination, suddenly MJ heard again the noise, it was like a sound of electricity, suddenly the lights went out, MJ screamed and quickly grabbed her phone to light the room.

The house was empty, the sound was coming from the basement, she thought that it could be the circuit breaker, after some steps the noise was louder, she turned on her phone and looked, no more steps, but a figure was moving in the shadows, MJ was getting more and more afraid, but the noise was there, and no one could be heard, MJ ran to the circuit breaker and quickly turned it on, the light came on immediately showing that the basement walls were covered by a black thick goo.

MJ looked confused for a moment but she quickly recognized what was that black goo.

"That's Venom's symbiote !"

She panicked and tried to run to the stairs but it was already covered in tentacles and more of them were coming.

The tentacles got hold on her feet and threw her into the ground, MJ couldn't think straight, she didn't know how the symbiote could be alive, she thought that Peter and the others had taken care of it.

More tentacles came from the darkness and MJ tried to crawl away but the only thing that she managed to do was turn around, the next thing that MJ saw were the tentacles opening her legs.

"What are you doing !? Stop !"

But the symbiote didn't stop, the tentacles went inside her pants and her jacket and started to take them off, MJ struggled, trying to hit the symbiote, but she wasn't strong enough, her shirt was opened showing her big tits, MJ was completely naked.

She tried to get up, but more tentacles held her and spread her arms, the next thing was the symbiote's head coming from the darkness, MJ tried to scream but a tentacle was already covering her mouth, the symbiote's face was smiling and said: "shh, don't worry we are gonna have fun."

The symbiote licked her pussy and started to get his tongue inside, MJ was moaning, trying to get her mind away from the pleasure but she couldn't, she couldn't resist and slowly gave herself to the pleasure, the tentacle on her mouth was removed and MJ said: "yes, please keep licking, I need you"

"I am so happy that you decided to join, my host."

The symbiote started to go up to MJ's tits and sucked on her nipples.

"Yes, suck on my tits, fuck, please keep going"

The tentacles that were holding MJ's hands started to get tighter, and the one that was spreading her arms started to lift her.

MJ was suspended on the air and the symbiote's head was getting closer and closer, MJ's legs were already wide open, waiting for the symbiote.

"We are one"

The symbiote penetrated her, it was a big and hard tentacle cock, MJ moaned and was breathing heavy, the symbiote started to penetrate her, fast and deep, MJ's eyes were rolling back, she couldn't think of anything else.

"This is...so good..."

"Oh, you love it, right? My cock is the best you ever had, isn't it?"

"Yes, yes it is."

"Well, here's the real deal, bitch!"

The symbiote got out of her, leaving MJ unsatisfied, the tentacles that were holding her fell and MJ fell into the floor, MJ looked up and saw that the symbiote was bigger, she looked at the floor and saw that a puddle of goo was moving into a female human figure, it was the size of her but it was empty, it was like a suit made for her.

"Wear me and we will be one, and all this pleasure is gonna be yours"

"No, I won't, Peter will come and he will destroy you"

"you still resist you stupid bitch" Venom said angrily as it shot tentacles toward MJ to pull her to the suit.

MJ dodged by luck and ran stairs up, the symbiote roared and jumped towards MJ, she closed the door and heard the liquid mass hit the door, the tentacles were hitting the door and trying to pass through the little gaps, MJ ran to the kitchen and hid on a closet, hoping that the symbiote would go away.

MJ waited there for half an hour inside the closet, she heard a few sounds afters she hid there bu she didn't heard anything in a while, slowly opening the closet, MJ went to the window to look if the symbiote was gone, there was nothing.

She sighed in relief and was about to call Peter, but her phone wasn't there, MJ looked in all the rooms and didn't found it, she searched all over the house until she realized that her phone was in the basement, she thought that the Symbiote gave up searching her so there would be no problem going to the basement, she saw the door closed and reluctantly grabbed the handle, she waited for a moment and when she was about to open the door she felt something falling on her back.

MJ fell on the floor due the weight, she looked back and saw the Symbiotic suit engulfing her skin.

"No! NO!"

"You are gonna be our host!"

MJ was struggling as hard as she could but the suit was already covering her tits, the suit didn't took long to cover her torso and start to spread to her legs, the tentacles were moving and trying to get her hands and legs covered, and they were succeeding, the symbiote was now covering MJ's arms and her legs, the tentacles were covering her fingers and toes and making her nails became sharpen claws, the suit was almost complete, the symbiote head came out of the back of the suit and was looking directly at MJ.

"Don't worry, you will enjoy this, our hosts always do"

MJ tried scream but half of her head was already covered muffling her screams, she quickly got up and started pulling the goo of her skin desperately, her body was trembling due the fear and her attempts to remove the symbiote were useless, the skin that became visible on the middle of the goo were almost immediately covered again as nothing had happen, MJ was becoming more **** and the Symbiote was becoming more and more impatient.

From her back emerged two large tentacles that quickly penetrated her ass and pussy making her fall on her knees, her screams were still muffled and her vision was getting blurry, her mind was being overtaken by pleasure and the fear of the loss of control, the symbiote was almost complete, the only uncovered part were her face and some pieces of her hair.

"Stop fighting bitch you're about to become a sex queen and the first piece to my world domination plan."

"Never, you sick monster."

"Then I will take over you body"

"Never"

"And if I do"

"Peter will find me, he will stop you"

"How is your boyfriend supposed to find you, he doesn't even know that I am here."

"He will, he's gonna destroy you"

"Oh really? We are sure that YOU won't let this happen" Venom said as little tendrils from the inside of the suit invaded her nipples.

"Wha-Ahhh! What are you doing"

"You'll see."

MJ's nipples were growing into a pair of huge boobs and her tits were getting bigger and fatter.

"What the hell, stop it! Stop it"

"Your mind may deny us but your body is saying otherwise."

The tendrils were now covering the entire breasts, her nipples were the only things that were visible and were leaking milk.

"Ahh! N-No! Stop"

"See, your nipples are dripping, and I bet your pussy is also"

"I-It is not."

"Let's check."

A new tentacle penetrated her pussy, MJ couldn't help but moan, her legs were shaking and her vision was getting even blurrier.

"I can feel it, you're so wet."

"S-Stop"

"Do you really want us to stop, or maybe you are just denying the pleasure that your body is feeling"

"You're sick, monster"

"Well, we'll need to make you a bit more submissive, so you will become the perfect bitch soldier of my army."

MJ tried to respond, but the symbiote already had her tongue covered in the goo and it was invading her mouth.

"Good, now, let's give you a taste of the pleasure."

The tentacle that was on her mouth went deep into her throat making her gag, MJ's mind was starting to lose focus, the other tentacles were pumping faster and faster, the goo that was invading her ass and pussy was making her even more horny and was also giving her pleasure, MJ could feel the tendrils that were still growing her breasts.

Her boobs were already almost double of the original size and were dripping a lot, her pussy was wet and her ass was sensitive.

"N-no, stop it, stop."

"We are not going to stop, the pleasure is just beginning."

Suddenly MJ felt something inside her head, it was like a voice telling her to submit, and it was getting louder, her eyes rolled back and her legs started shaking even more.

"Submit"

"No, never."

Suddenly her arms started moving by their own groping her breasts, the pleasure was unbearable and MJ could no longer deny her needs.

"That's right, give yourself to us."

"S-Stop, no more."

"Don't be like that, your body is enjoying this."

"No"

"We can feel your arousal, the heat from your pussy is burning, the taste of your milk is so delicious."

Her hands continued moving by their on and now instead of her breasts they were fingering her pussy and anus, the voice in her head was getting louder and louder, and her vision was going white, her whole body was shaking, the goo that was surrounding her nipples was making the breasts look bigger and fatter.

"Now, be a good girl, and let me fuck you, we both know how much you want it, so do it."

"No, n-n-no."

"You still resist bitch, you don't give us another option than make your brain useful for our purposes."

Venom sent several little tendrils inside her ears making direct contact with her brain, the little tendrils started to inject hormones that made her body 100 times more sensitive, in a single touch she would climax, now with her whole body covered she was cumming non-stop.

"Now, let's give you the last step to make you ours."

The symbiote's tentacles were now covering her face and the symbiote was about to fully take over her, she could feel her eyes were closing and she could not longer open her mouth, but she could still hear and speak, but now she had no intention to fight back.

"I-I"

"What are you going to do?"

"I'm all yours."

"What was that, you will have to be a bit louder."

"I said that I'm yours."

"Good, and now what will you do?"

"Whatever you command."

"Perfect, then you will serve us as our bitch, you will obey us and will fuck who we tell you, understood?"

"Yes"

"We are a symbiotic organism, and your job is to serve us and bring more hosts for us."

"Yes"

"Good, now, I will take over, and we will dominate this world."

The goo that was covering her face slowly dissolved showing her face, her lips were black and her skin was healthier than ever.

MJ got up looking at her new body, the goo that covered her body now had become a thin layer that covered her body, her curves were sexier than ever, her breasts were the size of melons, the body fat of her waist was moved to her butt, now her waist was thinner and her butt was larger.

MJ turned around and went to her room, the symbiote was happy, everything was working, now it just needed more Symbiotic cells, there were two ways of doing that, the first was consuming more biomass, it was efficient but slow, the second one was to fertilize some of her ovules, it was much faster but it would generate enough cells to convert one or two new hosts.

MJ was standing on front of a mirror, the symbiote's goo was completely covering her skin, making it look like latex, the symbiote was smiling and she was thinking.

"So, we are going to have fun, right?"

"Yes, and now that you're ours we are going to have a great time."

Part of her suit started melting and made a puddle on the floor right under her, the puddle started moving making strange movements as a large cock-shaped tentacle emerged from the centre of the puddle, it was 18 inches long and 6 inches wide.

"This will be the most fun we had"

"Let's start"

MJ squatted until the cock touched her butt, she inserted it inside her pussy and started going up and down with her hips, MJ was moaning loud and her boobs were bouncing with every move.

"Fuck yes, this is what we were waiting."

"You're so tight and your ass is amazing, you're perfect for our plans."

"Oh fuck yes, you're so big, this is incredible"

MJ was going faster and the cock was getting deeper, MJ could feel her pussy expanding to fit the cock.

"Ahh, ahh, yes, more, give me more"

"As you wish, you fucking whore"

The cock grew and was now 20 inches long and 7 inches wide, MJ couldn't contain her orgasm anymore and she was climaxing every time the cock hit her womb, the symbiote's cock was throbbing and was close to explode, MJ felt a warm liquid filling her.

"Look at you, you're pregnant with our seed"

"Yes, please, give me more, fill me with your seed"

"Of course"

MJ was moaning and cumming, the symbiote's cock was still releasing it sperm inside her, her ovules were already fertilized and in a few minutes the new Symbiotic cells started to gush from her pussy, the new Symbiotic cells fused with her body, making her bigger and stronger and while she had more Symbiotic cells that her body could absorb she could shot those cells as projectiles or tendrils.
