This is my first story I've ever written, about the origin of my original symbiote character, Vex.Please leave comments and critique so I can improve my writing style! I'm a bit nervous since I've never done something like this before.The absolutely wonderful comic sequence was done by the incredibly talented “Hailey, why did you buy this?” Hailey asked herself with a sigh.She held up the suit and eyed it up and down. It was a one piece, mostly black with a yellow pattern that seem to stretch throughout the outfit. It was shiny in texture, but Hailey wasn’t actually sure what it was made of. It felt unnaturally smooth; unlike anything she'd felt before. It was as soft as silk, and smooth as though it were made of glass.She flipped it over, looking for a tag of any sorts, but couldn’t even find that, it almost looked like it was supposed to be some sort of wet suit, but it didn’t even have any seams. If all that wasn’t strange enough, it felt super light in her hands. Hailey held the suit up to herself and looked in the mirror. Was it even going to fit? There was only the neck hole to fit in through, so she hoped it would stretch enough. She figured that she might as well try it on.---------------------------------------------------------------------------------------------------The day had started normally enough, with Hailey crawling out of bed, grabbing some cold pizza out of the fridge, and slumping into her chair as she browsed the internet on her laptop. It was her day off today, so she could just spend the day doing whatever she wanted, and what she wanted was to do nothing. That’s when she noticed the large rip down the side of her pants.“Dammit, how did that happen? Ugh.”Now her day of nothing was ruined. She slapped on some shorts she had lying around and pulled on a very old hoodie that was definitely too small for her. It probably would be a good idea to pick up a new one of those too. She definitely couldn’t afford anything new though, no. She would stick to the place she would always end up going whenever she needed something, a place she knew all too well because of her meager salary: the thrift store.Hailey browsed the racks of clothes as quickly as she could. The sooner she was out of here, the better. All she had to do was find some okayish looking jeans, a baggy hoodie, and she could also use some socks. Well, maybe she could afford some cheap socks that weren’t from the thrift store, because thrift store socks are always a gamble. Lost in thought, that’s when Hailey almost tripped over a box in the back of the store. She looked down at what had caused her stumble, and that’s when she saw it.The suit.It was just lying there, haphazardly thrown into the box. Curious, Hailey picked it up. Was it some sort of Halloween costume or something? It looked much higher quality than anything else in the store, but it was just sitting in this unmarked box, no price on it or anything. Hailey just stood there, staring at the costume, until she came to her senses and threw the suit back into the box, kicking it back under the shelf. She wasn’t going to a costume party, all she needed was some casual clothes, what was she doing? She started walking away, but then stopped, turning back to look at the box. She just couldn’t shake this feeling, like it was calling to her. She wanted the suit. She needed the suit. She didn’t know why she needed it, she just knew that she had to have it. Grumbling to herself, she walked back to the box and hastily grabbed the outfit out of it, and walked up to the front counter.“How much for this?” Hailey asked the clerk, putting the costume out on the counter. The clerk lazily looked up from the magazine she was reading and eyed the costume.“Hmmm”, she said as she picked it up, slowly flipping it over and inspecting it. “Hmmmmmmm.”Hailey started tapping her foot impatiently.“Fifty bucks.” The clerk said in a bored voice.“What?! Fifty dollars?! This is a thrift store!” Hailey said angrily. She barely had that money right now, and if she bought it, she wouldn’t have anything left to buy her other clothes.“I think some celebrity dropped that off with a bunch of her other clothes. Take it or leave it.” The clerk said, turning back to her magazine.Hailey frowned, staring at the costume for a few moments, biting her lip. “Fine.” She snapped at the clerk with a frown as she pulled out her wallet and grabbed all the cash that was in there, sliding it towards the clerk on the counter. She grabbed her new suit and walked out the front doors, muttering under her breath.---------------------------------------------------------------------------------------------------Hailey turned to look at herself in the mirror. She felt ridiculous. This is the thing she’d needed so badly? God, she’d have to eat cold leftovers in the fridge for like a week now after spending that money. And for what? So that she could look like some lame super hero? What would her powers even be, being able to know the exact number of freckles she had on her face? Honestly though, the most surprising part for her had been how easy the costume had been put on. Even though it had looked way too small, the costume had slipped on ridiculously easy. It fit her like a glove. Well, mostly. Hailey had been a late bloomer in high school, but when puberty finally hit her, it hit her like a truck, leading her to have a very “upfront personality”. So while the costume fit most of her figure perfectly, it was still a bit tight in the chest area. Looking in the mirror though, she had to admit she did kind of like how it made her boobs look bigger than they already were.Hailey suddenly jumped to attention.“Who’s there?”Before she even finished shouting the words, her bust suddenly exploded outwards.Hailey stood there in stunned silence. Her eyes were wide with shock and her mouth agape as she quickly looked back and forth from the mirror’s reflection and back to her chest. What the hell had just happened? One moment she was just standing there, then she heard a voice, and suddenly her breasts had surged forward. Each one was now at least double the size of her head! Was this some sort of... inflatable suit? She gingerly placed her hands on the sides of her new breasts and pushed them together. It was definitely not just the suit. She could feel everything. And the suit definitely wasn’t tight anymore. She went to grab the edge of the suit at the neck line to take a look at what was going on under there, but found that she couldn’t. She wasn’t able to peel it off at all, almost as if it was part of her skin. She probably would have been more freaked out about that if she didn’t suddenly realize her new assets were throwing her off balance as she slowly started tipping forward.“Who are you?!” Hailey shouted as she struggled to stay upright.And that’s when two black arms shot out of her sides, causing Hailey to yelp with surprise and let go of her rack, which the new arms quickly grabbed a hold of and hoisted up.Hailey stared at these new arms with a mixed expression of confusion and horror. They came out of her sides, just below her armpits, and seemed to have the exact same yellow pattern as the ones the suit had come with. They were just as long as her own arms, except they looked more muscular. “What the shit?” Hailey said quietly as she slowly dragged her hands across the new arms. And just like with the breasts, she found that she could feel everything, as if she was stroking her own arms. She could even feel her huge tits in these other hands. Hailey furrowed her brow and concentrated on closing her hands, and lo and behold, could feel all four hands she now had squeeze the flesh they were each holding. Using her normal arms, Hailey ran her hand through her blonde hair, something she did when she was nervous, and put the other hand on the back of her neck. She flinched when she felt there was something there, and quickly turned back to the mirror to see that the costume’s neck line had gone all the way up, and was even now starting to creep onto her face. And was it just her, or were her eyes a different color than before? If anyone saw her, they’d probably think she was some huge monster or someth-"NO! Wait!” Hailey cried out in vain as she felt her entire body slowly start to stretch. It was a strange, yet not entirely unpleasant sensation as she started to rise above her room. The floor seemed to get farther and farther away as if she was slowly floating upwards, but her feet were still on the ground. Not only was she getting taller, but just all around bigger. Even her butt felt like it was rounder than before, and she could feel the muscles in her arms enlarging to match her second set. The suit continued crawling upwards over her face, and Hailey started to panic. She stumbled backwards into her book shelf, which she was now taller than, knocking it over. She suddenly bumped her head which made her wince and she reached up to rub her head while the other arms let go of her chest and tried to stabilize her. Her boobs fell against her stomach and she realized that they too were growing once again. And if that wasn’t bad enough, she realized the bump she had felt was her head hitting the ceiling. Hailey had now grown so much she had to start to bend down to fit in her own apartment. Her body started pushing furniture out of the way as it continued to grow, and as her back leaned against the top of the ceiling, she could feel her breasts start pressing into the floor. All the while she could feel this... presence in the back of her mind. It almost felt... giddy at what was happening. But that was the least of her concerns right now. She had a small apartment, and if she kept on getting bigger, this wasn’t going to end well. She could hear the floorboards creak and grown under the massive new weight. With one last desperate plea, Hailey closed her eyes and shouted out,“PLEASE STOP!”And with that, the growing came to an end. Slowly opening her eyes, she surveyed her surroundings. Her back was completely against the ceiling while she was in a squat, and her breasts were absolutely enormous, stretching all the way onto the floor, pressing into the sides of her knees. Her four arms were stretched outwards all over the room with one on the ceiling, one on the wall, one on the floor, and one trying and failing to contain her tits. She looked down at her hand on the floor and saw her laptop laying beside it. Compared to her, it was now small enough to fit in the palm of her hand. How the hell was she supposed to fix this? And her apartment was a complete mess. That’s when she felt the other presence in the back of her mind again. Except it didn’t feel giddy anymore. It felt more... guilty.“Hello?” Hailey said, not sure if she was expecting a response. “Thank you for stopping”Hailey realized she wasn’t actually hearing this, but it was being spoken with a soft, almost innocent voice, directly into her mind.Hailey couldn’t help but feel bad for it, almost as if she knew what it was going through, feeling what it felt, sharing its emotions.“Uh, hey, that’s ok, nobody’s hurt. I just need to know if you can put me back to normal.” Hailey said, trying to stay calm and reassure it that she wasn’t mad. She bit her lip with concern, and realized her teeth were much sharper than she remembered.Hailey let out a sigh of relief as she felt her body start to shrink. She was definitely going to have to have a talk with this.... thing to figure out what was going on. This certainly wasn’t the day she was expecting to have today. Maybe she should call in sick tomorrow, just to really get things sorted out. Some day of nothing this was turning out to be. But honestly, the worst part about this whole thing?She had kind of enjoyed it.
