Captain Marvel Symbiote - Superpowered

“I’m home!” Jane said, closing the door behind her. She had just gotten back from visiting a friend for coffee and had expected to see her boyfriend Mark waiting for her, but even as she called his name a second time there was no response. Jane put down her things and walked further into their house. She could see the remote control on the side of the sofa where Mark had undoubtedly been watching TV only moments before but he was nowhere to be found. “Probably got his headphones on…” Jane said quietly to herself as she walked further in.

She noticed that their bedroom door was ajar and smiled to herself. Had Mark thoughtfully set out the costumes ready for her to try on? She had bought some in preparation for her party later that night and wanted to see what would fit. But, when she pushed the door open, she could see the bags for the costumes were empty on the bed, the costumes gone, with her boyfriend similarly absent.

Jane was just about to get worried when she heard the bedroom door close behind her and turned with a yelp. Inexplicably, now blocking the only way out was the character Black Widow, as if she had just stepped off of the set for the Marvel films. Jane screamed and jumped back.

“What’s going on? Where’s Mark?” she said, scared. The figure turned her head to one side playfully, her red hair hanging over one shoulder as she did so.

“He’s perfectly safe, Jane”, Black Widow said with a smile, her pink lips thick and seductive. Jane felt frozen, Black Widow towering over her small body.

“How do you know my name?” she asked, trying to back away further but her body refused. She glanced at the empty costume bags on the bed and then to the mysterious figure, remembering the two costumes she had bought: Black Widow and Captain Marvel. “Is that my costume?” she asked, incredulous. She had only taken a quick look at the packages back in the costume shop, but they seemed realistic. She never expected for them to look this good.

“In a way, I suppose”, Black Widow said mysteriously, tracing one gloved finger along her neckline, teasing with the zipper that was struggling to contain her large, round breasts. “But truly, it’s something so much more. Mark tried me on, and he wasn’t disappointed”, she added with a predatory grin.

“You’re Mark?” Jane said, yet more surprised. But, as she looked into the piercing eyes of the super hero come to life in front of her, she did get the instinctive sense that Mark was nearby. Somehow, Mark was Black Widow.

“Yes. He decided to try me on. Now, it’s your turn to suit up”, Black Widow commanded. She gracefully pushed something forward with her feet. Looking down, Jane could see the two heavy boots of the Captain Marvel costume, with the rest of it in a loose tumble around it. It was the exact match of the ones worn on screen, a heavy, tough red with golden accents. The rest of the costume was in a blue, red, and gold pile, and Jane thought she saw it twitch slightly. “Don’t you want to just see how it feels to be strong and powerful? Just slipping your feet in won’t hurt, will it?” Black Widow said. As if in a trance, Jane felt herself walking towards the shoes. She knew she should try and run, to try and find out what happened to Mark, but the woman’s voice was likely velvet in her ears. She felt compelled to obey. Soon, her bare feet were poised, ready to slip into the boots. She lowered them down into the open holes, and gasped as a thrill overtook her. A smile crept across Black Widow’s face.

As Jane’s feet reached the thick soles of the boots, she realised immediately the costume was far too big, her feet almost able to twist around at the ankle without coming into contact with the mysterious leather. Within a second, however, she found the boots fitting much more comfortably, as if they had shrunk down to perfectly fit around her two tiny feet. Jane felt stunned as she looked at the costume and realised that the boots hadn’t shrunk – her feet had gotten bigger. She curled her toes, slowly coming to terms with the large feet she now had. Despite the oddity of the situation, Jane didn’t feel strange. If anything, she wanted more. She could feel her calves swollen with muscles, the leather flexing to accommodate them. Curious, she lifted up the blue fabric of the legwear, feeling its supple strength between her fingertips. She tugged at it, lifting it over her knees. Once again, it was loose at first, before her body grew stronger and broader, powerful, shock-absorbing knees stretching out the fabric with a creak. Jane knew she was grossly disproportioned, with her large, bulky lower legs and tiny upper body, but her inquisitiveness had been piqued and now she knew she needed to see this through to be fully satisfied.

Just then, she felt Black Widow’s fingerless gloves on her shoulders, the woman’s breasts softly pressing into the small of her own back. Jane knew she should have been surprised, having not heard the woman’s stealthy movements, but her presence was oddly reassuring. She leant up against her, finding it hard to mask her excitement. Black Widow’s small fingers deftly pulled off her top, tossing it across the bedroom, soon followed by her shorts and underwear that were disposed of with similar skill. Jane knew it would be impossible to leave now, her feet stuck in the heavy costume. She was helpless as Black Widow’s fingertips began to rub at one of her breasts, the other creeping lower to a far more sensitive spot.

“Good girl”, came the silky voice in her ears. “But I’m afraid this is only the beginning. There are a few more steps to follow  if you’d like to join Mark in his world of bliss”, she said enticingly. Through trembling lips, Jane moaned assent, Black Widow’s skills making short work of her overwhelmed senses. She could feel how wet she was getting, her legs trembling despite their sudden strength.

Now, the rest of the costume appeared to take a life of its own. The upper legs squeezed over her small thighs, bulking out with fat and dense muscle. Then, the groin of the suit hovered before her moistened slit. Impossibly growing out of the fabric came a long, thick tendril, red and blue. The head of it was tipped with a shining golden star.

“All you’ve got to do is to let it in”, Black Widow whispered. Jane knew she needed to try and break away, but the pseudo-penis in front of her, enticingly waving mere inches from her already wet pussy was impossible to ignore. She knew she needed it inside of her. She wanted the strength that was promised. Jane spread her legs and leaned forward, letting the suit in.

Just as her own flesh changed shape within the suit’s fabric, once the gold-tipped shaft was inside of her, it seemed to grow thicker. Jane panted in bliss, the suit pumping her and teasing her clit, Black Widow’s hands now no longer needed. She felt the waist of the suit squeeze tight around her, the red belt sealing around her with a leathery creak. Her ass swelled, no longer barely noticeable but now round and athletic. Jane leaned forward and ran a finger over the soft but supple leather covering her womanhood. Despite the rapid movement of the suit within, playing with her body, there was no evidence of it from the outside. She felt something teasing at her anus, somehow knowing it was another probing tendril. Jane knew she was already in too deep, but didn’t care. The thought of being more than she was – more powerful, more impressive, was all that she cared about now. As if the suit could detect she was already close to orgasming from the power trip, it wasted no time in pushing her over the edge, Jane’s toes curling once more inside of her heavy boots. Her anus loosened, and the tendril slipped pleasurably inside and began to push through her.

Jane knew that she would have contentedly stayed like this for hours, the suit massaging her anus and vagina like some perfect, tireless lover, but she needed more. Eagerly, she grabbed at the suit, pulling it higher. Black Widow’s fingers helped press it close against her skin as she moaned.

“Perfectly strong”, Black Widow said, poking at Jane’s once tiny gut. Now, it was broad and tough, her abdominal muscles tensing in response to her touch. Jane traced one finger over the blue pattern, the cut emphasising the slight curves of her lower half brilliantly. Looking to Black Widow, Jane realised something. She was now able to see the top of Black Widow’s head – she was taller than her. Somehow, the suit was increasing her height. Jane grinned. She felt unstoppable.

Before Black Widow could even help her, Jane shoved her arms into the sleeves of the suit, feeling the bulky red gloves mould to fit her now powerful arms. She flexed her muscles excitedly, having never felt this strong in her life. The star on her chest filled her with pride as she saw it adjust, her small breasts growing several cup sizes beneath it. All the while, another star was subtly thrusting inside of her, bringing Jane to new heights of pleasure.

Jane took a careful step, feeling the reassuring weight of her body as the floor beneath it creaked. Rather than being worried, this only filled her with delight. She knew that she could run straight through the walls of the bedroom if she wanted to, and it wouldn’t even slow her down. The suit squeezed in tight across her neck, with only her head left to change. As she looked down, Jane’s new suit and the new body within it filled her vision. She could tell that the suit was armour, but she knew that the real strength came from her body, her tight muscles squeezed and supported by the creaking, tight leather, perfectly fitted.

Black Widow moved gently in front of her, looking up at the now much taller woman. Inside her, Mark writhed in pleasure, and Jane’s body reached a new climax in unison with him. From the neck of the yet unfinished suit, Black Widow fished out a large, fleshy mask. Jane could see blonde hair hanging from it.

“One last step and you’re ready to join the team”, Black Widow said with a conspiratorial smile. Jane smirked. She knew that if she so chose, she would be able to launch the smaller woman out of the window with a firm backhand. She held all the power here, and sinfully it was turning her on.

Black Widow held out the mask, and Jane could see the eye holes within where she knew she wanted her own eyes to fill. A wet tongue drooled out of the front of it, the strong jawline hanging loose. Black Widow began to kiss the mask, and Jane could see that the tongue was as alive as the rest of the suit, sucking and licking at Black Widow’s pouting lips. Jane found herself imitating the same movement, desperate for that tongue to be hers. Black Widow pulled back, a thin bead of saliva connecting her tongue with the mask and held it out in front of Jane. Jane’s large hands easily brushed aside Black Widow’s, and as she pulled the tight mask over her face, she could feel Black Widow already kissing it as it made contact.

In an instant, Jane felt something wet and slippery slide into her mouth, squeezing past her own tongue and sliding down her throat, carefully allowing her pleasured breaths to escape. It darted down into her stomach, interlocking with the other tendril that was already nesting deep within. Jane was part of the suit, inside and out.

Captain Marvel opened her eyes, running one long finger along her jawline with a confident, satisfied smirk. She knew she didn’t need to say anything to Black Widow ahead of her, the more dexterous woman wrapping her legs around her waist as Captain Marvel lifted her easily, the two passionately kissing. Wrapped tight within the suits, Jane and Mark were in bliss. Captain Marvel tossed Black Widow onto the bed, the woman landing with a thump. She cracked her knuckles and joined her, eager to find out what her new strength was truly capable of.
