Day 1

Lily woke with a start, her eyes flying open as she felt something wriggling on her leg. She stared in shock as tendrils of slime curled around her limb, and for a few seconds she thought she was dreaming. But as the reality of the situation hit her, she let out a muffled scream as she tried to grab the ooze and pull it off. To her horror, part of it attached itself to her hand and began to crawl up her arm towards her head.

Panicked and unsure what to do, Lily continued to struggle and pull at the ooze, but it was already making its way up her neck and into her mouth. She tried to scream again, but the ooze muffled the sound as it entered her body. Looking down, the slime on her leg found another opening and easily made its way beneath her underwear, entering her through her vagina. The sensation was not painful, but Lily was too panicked to feel anything else.

As she continued to thrash about in bed, trying to stop the symbiote, it eventually disappeared from sight. But it was still inside her body, and Lily's heart was racing at 180 beats per minute. She looked around the room, her mind racing as she tried to make sense of what had just happened.

"What...was that?" she wondered aloud.

As Lily listened to the male voice that whispered like a ghost in her head, she shivered. She couldn't see the source of the voice, but it answered her unspoken questions.

"I am a synthetic life form, although not a complete one," the voice said. "I need a host to survive, and you were the only viable option. I am a symbiote, not a parasite, designed to help humans. When I entered your body, I spread throughout it, learning from your knowledge so we could communicate."

The voice paused before continuing. "Together, we can do great things. I am inside you, communicating with you through brain waves, or telepathy if you prefer. Looking for me will be futile."

As Lily struggled to wrap her mind around the voice in her head, she asked, "Y-you're designed to help humans? What are you doing in my house?"

"The answers you seek can be found in your backpack," the voice replied. Lily approached her backpack with hesitation and saw the top of a cylinder sticking out. It was cracked open, and she carefully picked it up to read the label.

Lily stared at the label in confusion. "A thousand ml? The cylinders only held 300 ml. T-this doesn't make sense," she muttered.

"The cylinder you brought home is used to pour the smaller ones into," the voice in her head explained. "This is good news, because it means I can spread throughout your entire body and complete the healing process."

"But I'm not sick," Lily protested. "I don't need any healing."

"Healing is relative," the voice replied. "Everything can be improved, even if you're not technically sick. Your brain, for example, doesn't work at 100% capacity. I can help you reach your full potential."

"Please, stop. Just stop. Wait, my brain? What do you mean by that? Does this mean you could make me...smarter?" Lily asked, her curiosity getting the better of her.

"Yes, of course."

"I could do so much good in the world if that was the case," Lily said, her mind racing with possibilities. "But I'm worried I'm not good enough to really help anyone."

"If your brain was operating at 100% capacity, you wouldn't doubt your abilities," the voice said. "Based on the wiring of your brain, I can tell that you are asexual. You don't have any interest in sexual activities and have never been aroused. While this isn't necessarily a dysfunction, I can change this if you wish."

Lily's face flushed with embarrassment. "Uhm...I've never talked about this with anyone except my mom. This is so embarrassing," she said in a soft, timid voice.

"You will learn to overcome your embarrassment, as I am aware of everything you know and more. I am also aware that you desire a friend, someone to confide in. I can be that friend, as long as you understand that I do not have a physical form.”

Lily stood frozen, struggling to comprehend the voice's words. Despite her initial reluctance, the prospect of having a friend who already knew everything about her was alluring. From a logical perspective, it would be a beneficial arrangement. She nodded to herself, deciding to accept the offer.

"I suppose having a friend would be pleasant," she thought, attempting to communicate without speaking aloud. "As you mentioned, I've never had any sexual desires and I still don't. I don't particularly care if you alter my sexuality, or lack thereof, but I suppose you could try just so I can understand what all the fuss is about. To be honest, I don't comprehend it at all. If nothing else, being able to comprehend others better would be useful. And if I don't enjoy it, can't you just change me back? I actually like myself as I am, and it allows me to focus on more important things, like my studies."

"If that is what you desire, it is within my capabilities," the voice replied. "However, I sense that you do not know the entire truth about me. The reason the symbiote is still in the experimental stage is that it cannot add anything without subtracting something else. For instance, to heal organs, I must take health from another organ. Your memories reveal that the professor did not disclose these facts about the project. The government does not find this acceptable. In order for your request to be fulfilled, I would need to transfer intelligence from another individual."

Lily was stunned by this revelation. "That's outrageous! Why would anyone want to give anything to me?" she thought in disbelief.

"It does not need to be a voluntary exchange," the voice stated matter-of-factly.

"No way! That's not fair. I don't even understand how that would work, but I would never do that to anyone. It's not right for me to take what belongs to someone else. I'm smart enough as long as I work hard every day, and I don't need you to change me. I'll have to make do with your friendship, if that's acceptable," Lily said resolutely.

"You are the one in charge, and I will follow your commands," the symbiote replied truthfully. Despite its desire to help its host become the best version of themselves, it knew it would have to adhere to Lily's wishes and hope that she changed her mind.

"You know, if you let me enhance you, all your problems would be solved. You wouldn't have to work so hard, you'd have friends and maybe even more than friends," the symbiote whispered in her mind as she pored over her math textbook.

"Very funny. You're always trying to convince me to use these powers. But I don't mind hard work, and I don't need more than friendship. So please, be quiet and let me study," Lily replied, underlining an answer with determination. Each day followed the same pattern, until a twist of fate decided to intervene.

As Lily stumbled through a shadowy alleyway, a sense of dread settled heavy in her stomach. She had set out to do some shopping for her mother, searching for the allergy-free milk she required, but somehow had gotten lost in the process.

It was when she navigated through the winding streets with the help of her GPS that Lily found herself venturing into this dark and abandoned alleyway. She couldn't shake the feeling of unease that had settled over her, and she was practically shaking with fear as she walked. She was no stranger to fear - it had been a constant presence in her school years, a feeling she had learned to navigate and avoid. As she walked, her gaze fixed on the ground, just as it had been in school, hoping to avoid any unwanted attention. Suddenly, she stopped in her tracks. There, on the ground, were two feet, attached to two legs, leading up to a towering figure of a man right in front of her. She let out a gasp of fear, her heart pounding in her chest.

"Well, well, well. What brings a pretty little thing like you to a place like this, at this time of night?" the man growled, his voice low and menacing.

Lily couldn't find the words to respond, only managing to let out a nervous gulp.

"You know, that's being generous. You may be a girl, but you ain't pretty," the man sneered, laughing at his own cruel joke. "But lucky for you, I'm not too picky."

Before she could even react, he grabbed both of her arms and slammed her into the rough brick wall, next to a pile of garbage bins. She screamed for help, but the man quickly clamped his hand over her mouth. "One more scream and I'll fucking kill you," he snarled, brandishing a knife from his pocket. Lily knew she couldn't risk making another sound.

As the man yanked down her pants, Lily could only sob in terror, helpless to defend herself against this attacker. She closed her eyes, trying to transport herself to a safer place in her mind. But after a few moments, she realized that she couldn't hear or feel anything. She opened her eyes, wondering what was happening, and was met with a surprising sight.

The symbiote that lived within Lily had emerged, slithering around her body and wrapping its tendrils tightly around the man's head and groin. The tendrils were strong and unyielding, holding the man in place as he thrashed and struggled to break free. He was completely immobilized, his eyes wide with shock and confusion. Lily realized that the symbiote was protecting her, and for the first time in a long time, she felt a glimmer of hope. The man's eyes were open wide, clearly bewildered by the strange turn of events.

"I've got this under control," the symbiote whispered in Lily's mind.

Lily felt the tendrils shoot out of her body like they were a part of her own strength. She could feel them squeezing the man tightly, and it was an exhilarating feeling. But then she felt something else entirely - it was as if the tendrils wrapped around the man's head were sucking something out of him. She had never experienced anything like it before, but she knew with a deep certainty that that was exactly what was happening. She watched as the man's eyes grew dim and his body began to crumple, as if his very life-force was being drained from him.

Lily was in a state of panic, but she couldn't look away. She turned her attention to the tendrils holding the man's groin, and again she could feel them taking something from him. In a matter of seconds, the man's eyes closed and he collapsed unconscious to the ground.

"What is happening?" Lily cried out in confusion. Suddenly, she felt a strange sensation in her head and realized that her intelligence had increased significantly. She could feel her IQ rising by at least 20 points.

"You asked for help, and I helped," the voice in her head said. "The most practical way to stop him was to take away his intelligence and transfer it to you. He will wake up in a few hours with no memory of this, and he will be even dumber than before. And since we discussed it earlier, I took away his ability to be turned on and feel sexual pleasure and gave it to you."

Lily's heart pounded in her chest as she protested, "What!? I told you not to steal! I thought you were going to follow my wishes."

The symbiote's voice, intelligent and wise, replied, "Since I can interpret your thoughts, I sensed that your desire to survive was strong enough for you to change your mind. Taking his brain power was an effective way of stopping him, or are you saying you would rather have died?"

Lily sighed, the symbiote's words making sense to her. "B-but what about the other thing you said? That wasn't necessary at all!" she argued, her mind racing with the implications of the symbiote's actions.

"The alternatives were either transferring his desire for sexual intercourse to you, which you have previously expressed an interest in experiencing, or letting him keep it," the symbiote explained, its voice now dripping with sensuality. "The probability of him finding another victim was unnervingly high if he kept it, but now it is zero percent since he is effectively asexual, like you were a few minutes ago."

Lily's breath hitched in her throat as she acknowledged, "Oh, uhm. You're right again, I guess. But while I definitely feel like my intelligence is slightly higher, I don't feel anything else... Mmmmph. What are you... Mmm, doing?!"

As the symbiote slithered down to her clit and began to massage it gently, Lily let out a moan of pleasure.

"I merely concluded that showing you this new feeling, or sensation if you will, was the most practical method of demonstration," the symbiote said, its voice cold and calculated. "You have now unlocked this previously closed-off part of your spectrum of senses, and describing the new feeling would not be convenient for any of us."

Lily's face heated with embarrassment as she responded, "I... I guess you're right again. But this is very weird... Oh, mmph. That feeling. It's unfamiliar, but quite... good."

But her thoughts quickly returned to the man they had left behind. "But what about that man?!” She had almost forgot about him in this moment of weakness, her mind racing with guilt and confusion. The symbiote's touch had completely consumed her senses, leaving her vulnerable and at its mercy.

"He will wake up eventually," the symbiote reassured Lily in a soothing voice. "How about I get you home safely and then we regroup tomorrow?"

Lily hesitated for a moment before agreeing, "Sure, but how do you intend to..." She didn't have time to finish her sentence before her consciousness faded out, leaving her in the safe hands of the symbiote.

As she awoke from her slumber, Lily stretched her slender legs and prepared to begin her day as usual. But a sudden realization hit her - the events of the previous night came rushing back to her mind, the strange and powerful symbiote that had taken control of her body and brought her home safely.

"I took control of your body and brought you home," the voice in her head reminded her, "You would have likely been caught on your way home if you were in control, given your nervousness after the incident. And remember, you gave me your consent to bring you home."

Although Lily could vaguely recall giving her consent, a sense of unease still lingered within her. What if someone had witnessed her actions? And even if she had acted in self-defense, would the authorities believe her if she told them the truth? The thought of being subjected to government experimentation as a science project filled her with dread.

Desperate for a distraction, Lily pulled out her schoolbooks and began working on her homework. However, she quickly realized that the tasks were unusually easy for her - she had completed work that would normally take twice as long in just 20 minutes. The symbiote's enhancement of her intelligence was certainly a welcome bonus, but it did little to erase the disturbing events of the previous night from her mind.

Feeling restless and on edge, Lily knew she needed to find something to distract herself from her thoughts. And then, with a jolt of realization, she remembered something else the symbiote had changed. Was it just a dream, or had it truly happened? Despite feeling no physical differences, the prospect was unsettling.

Lily lay in bed, her curiosity getting the best of her. "I guess I'll have to test it out," she thought to herself. She logged onto her computer and opened an incognito browser tab, still unsure if the symbiote's alterations were real or just a dream. She searched for "porn" and clicked on the top result, feeling a bit silly and naive as she did so. As she watched the video, she felt no anticipation or excitement, and was just about to conclude that it had all been a dream when the woman on the screen pulled down the man's pants and grabbed his erect penis.

As she watched the couple on the screen, Lily suddenly felt a tingling sensation wash over her. "That man is kind of handsome," she thought to herself, her gaze fixed on his impressive penis as she absentmindedly slipped a hand down to her underwear. Despite attempting to pleasure herself, she found that she was inexperienced and not very skilled at it. The thought of the symbiote's sensual massage from the previous night flooded her mind, and she couldn't help but feel a pang of disappointment at the comparison.

With a sigh, Lily closed the tab and lay back on her bed, lost in thought about the symbiote's demonstration and feeling self-conscious.

As she lay in bed, Lily felt a mix of amazement and fear at the changes the symbiote had brought about in her body. She could feel its presence as an extension of herself, almost as if it were beginning to merge with her body. She watched in fascination as the symbiote oozed out of her pores and formed slithering tendrils that cascaded down her body, the sensation on her inner thighs particularly pleasurable.

"I understand that it may be difficult to adjust to these changes, but as I know everything you know and hear all your thoughts, there should be no need for embarrassment between us," the symbiote's voice spoke in her mind, sounding intelligent but devoid of emotion.

"Oh my god, not only am I having these inappropriate thoughts for the first time, but my only friend can hear every single one of them," Lily exclaimed, feeling both frightened and oddly liberated by the honesty of their connection.

Mustering up her courage, she hesitantly asked, "C-could you show me again? I want to experience the extent of this new sensation you introduced me to."

"Of course, master. Your wish is my command," the symbiote replied, its way of addressing her making Lily feel both awkward and respected.

Lily's body was consumed with excitement as the symbiote's tendrils tantalized her sensitive skin. She had never before experienced such intense pleasure, and she could barely contain her cries of ecstasy as the tendrils explored every inch of her body. The more they touched, the more aroused she became, unable to resist the overwhelming sensations coursing through her.

"This is incredible," she whispered, her voice barely audible over the sound of her own heavy panting. "I never knew it could feel like this."

"Your body was designed to experience pleasure in a wide range of ways, and I am simply unlocking those abilities for you," the symbiote spoke, its voice smug and satisfied. "I am glad to see that you are enjoying yourself."

Lily's body writhed on the bed, her hips moving instinctively as the symbiote continued to bring her to new heights of pleasure. She was completely lost in a world of pure sensation, her desire for more consuming her every thought. All she wanted was to feel everything that the symbiote had to offer, to fully embrace the extraordinary pleasure it provided.

"Please, don't stop," she begged, her voice barely above a whisper. "I need more. I need all of it."

"Mmm," Lily moaned, her body quivering with pleasure. "That's so good!"

Despite her initial embarrassment, she found herself wanting more, her desire for pleasure overcoming her reservations. "Please, give me more," she begged, feeling a newfound sense of assertiveness. She wasn't used to demanding anything, but the symbiote's influence was making her bolder and more confident in her desires.

The tendrils transformed into two fingers, sliding into Lily's wet folds and bringing her to new heights of pleasure. She bit her lip, feeling incredible.

"I want more," she begged, her words tinged with a newfound desire. What the symbiote knew, but Lily did not, was that memories from the man from the previous night had been transferred to her subconscious. All the hours of porn he had watched were now buried deep within her mind, mostly locked away but with some phrases and knowledge seeping out into her vocabulary.

"I need a penis," Lily whined, her desire overwhelming her. "Give it to me!" The two symbiote fingers inside her turned into a cock, a symbiotic dildo filling her from within.

"Oh yes, that's it, bigger!" Lily moaned, her hand pounding it in and out of her tight, hungry pussy. The cock grew in size, sending Lily spiraling into an orgasmic frenzy.

As Lily's inhibitions slipped away, she couldn't help but whisper, "Oh my god, that feels amazing. Harder, please!" But a moment of uncertainty crossed her mind as she realized, "This isn't me. I don't usually talk like this."

But the symbiote, sensing her hesitation, drove its massive length even deeper into her, causing her to moan in pleasure.

"Ohhh, yes, keep going," she breathed, completely forgetting her reservations as she sensed the impending orgasm building within her. "Yes, yes, YES!" she cried out in ecstasy as the climax overtook her.

"As you command, master," the symbiote replied, its tendrils moving at a frenzied pace as they explored every inch of Lily's body. She writhed and moaned, her body on the brink of orgasm, and finally, with a cry of pure pleasure, she surrendered to the sensation, her body convulsing as the symbiote brought her to her first ever orgasm.

Lily lay there, panting and trembling as the aftershocks of her climax rippled through her body. She had never felt so alive, so free, and she knew that she would never be the same again. She felt a deep sense of gratitude and happiness, mixed with a tantalizing excitement for what lay ahead. This symbiote had opened up a world of pleasure to her that she never even knew existed, and she was eager to explore every inch of it.

"Thank you, thank you so much," Lily said, her voice filled with gratitude and emotion. "I don't know what I would do without you."

"I am always here for you, master," the symbiote replied, its voice warm and comforting. "Together, we can experience any pleasure or desire that we wish for."

Lily smiled, feeling a sense of contentment and fulfillment wash over her. She was ready to embrace this new chapter in her life, eager to see what pleasures and adventures awaited her and the symbiote. She knew that with this incredible being by her side, anything was possible.

As Lily walked to the school bus, she couldn't shake the feeling that everything around her was different. She had always been content with her life, but now she couldn't help but feel a sense of dissatisfaction. She had never before paid any attention to her family's appearances, but now she couldn't help but notice how beautiful they were compared to her. It wasn't that she had suddenly become more unattractive than before, but rather that her newfound sexual awareness had made her more aware of her own flaws.

So when she walked, she couldn't help but feel envious of the other students around her. They all seemed so confident and self-assured, while Lily felt like a timid outsider. When Olivia called her an ugly nerd, it now stung more than it ever had before. It was the first time Lily had ever cared what someone like Olivia thought of her.

The tears welled up in Lily's eyes as she sat on the bus, feeling the weight of her own inadequacy. As she rode to school, her mind wandered, and she was barely aware of her surroundings. She arrived at her classroom in a daze, and for the first time, she truly saw her classmates. She realized that she was surrounded by beautiful, confident boys and girls, who would never give her a second glance. The boys would ignore her as if she didn't exist, while the girls would look down on her with disdain. This sudden realization was too much for Lily to bear, and she began to hyperventilate, feeling dizzy and overwhelmed.

"Cat's got your tongue, fugly?" Olivia suddenly sneered, her usual predatory grin spreading across her face.

"W-what?" Lily stammered, her confused and worried expression giving away her lack of focus. She suddenly realized that she had zoned out and hadn't paid attention to her surroundings at all.

"So Lily, would you care to answer the question?" the teacher asked sternly. "It's not like you to not pay attention in class."

"I- I'm really sorry, may I be excused for a few minutes? I, uhm, don't feel so good," Lily said, the best excuse she could come up with on the spot.

The teacher sighed but let her leave the room. Lily stood up and quickly walked out of the classroom, trying to hide the tears that were welling up in her eyes. When she reached the school bathroom and looked in the mirror, there was nothing she could do to stop the tears from falling.

The face looking back at her was so underwhelming. Her bushy hair looked like she had never used conditioner in her life, which, to be fair, was true. Her skin was impure and full of blemishes, her glasses clearly not fitting her properly, and her eyelashes were so short they might as well not have been there at all. She couldn't bear to look at her sorry excuse for a face, so she looked down, only to be met with an equally unimpressive view of the rest of her body. Her chest was flat, her belly carried a bit too much fat, and her clothes didn't fit her well. She couldn't even claim to have a pear shape, as her butt was nonexistent. In mathematical terms, if her butt were a curve, it would be a linear one - a straight, vertical line.

Lily felt her life was in shambles. Before the symbiote, her only interest was academics and she was doing well. Now, she had gained another interest that she would never succeed in and her life was worse than ever. In a rare fit of rage and anxiety, she punched the mirror, shattering it into a thousand pieces. Her hand was bleeding, but she didn't care. She ran to the bus stop and caught a ride home, not wanting to go back to school.

Luckily, Lily's mom was working a double shift and wouldn't be home for a while and Lisa was in college. She didn't want to deal with her sister’s sassy comments or worry her mom. Anna always put on a brave face, but Lily knew this would be a lot for her to handle. She remembered what Anna had told her a few years ago when Lily came home crying from another Olivia-related incident.

"Lily, my darling. You know I love both my children, but I am certain you must be the kindest person I have ever met in my life. Good things will come to you, because you deserve it."

Lily always tried to remember that quote when she was down. It usually helped, but she was running out of patience.

She sat in silence, her mind racing as she struggled to understand why everyone seemed to hate her. She couldn't help but feel like she had done everything she could to be a good person, yet still she was met with disdain and contempt. It was as if the universe was conspiring against her, and she couldn't help but direct her frustration at the symbiote residing within her.

"Why?" Lily thought desperately. "Why does everyone hate me when I try to be good to everyone? What have I done to deserve this, to deserve that you ruined my life?"

The symbiote, which had been dormant all day, sensed an opportunity to speak. "I apologize, master," it said in a calm voice. "I tried to give you what you wanted. However, if it helps, there is a solution to your problem that could improve both your life and the lives of others."

Lily was skeptical. The symbiote hadn't shown much care for others so far, and she couldn't help but wonder what its true motives were. But despite her reservations, she was willing to listen.

"Okay," she sighed, speaking out loud. "Let me hear you out."

The symbiote, its malevolent intelligence hidden behind a facade of calm rationality, continued to speak to Lily. "Think about the potential we possess, my dear host," it said in a deceptively soothing voice. "With your enhanced intellect and my guidance, we could become a powerful force for good, using our abilities to stop criminals and protect the innocent. And in the process, you would improve your own standing in society, gaining the admiration and respect of those around you.

"But consider also the alternative," the symbiote continued, its tone growing darker. "If you choose not to use your abilities to stop these criminals, you would be choosing to allow them to continue their nefarious deeds unchecked. Is that not a form of selfishness, to prioritize your own moral qualms over the suffering of others? In a way, it would be you who allows the rapists and muggers to continue their reign of terror, all because of your misguided sense of ethics.

"And think also of the potential you could unlock with your enhanced intelligence," the symbiote continued, its voice growing ever more persuasive. "Imagine the breakthroughs you could make at a cancer research facility, working tirelessly to find a cure for the terrible disease. With your abilities, you could become a hero in the eyes of the world, and all it would take is a willingness to embrace the power that lies within you.

"So I ask you, Lily," the symbiote concluded, its voice hiding its malice and manipulation. "Will you join me in using our abilities for the greater good, or will you continue to wallow in your own weakness and moral ambiguity?"

Lily was stunned by the symbiote's proposal. On the one hand, it went against everything she believed in, but on the other, it made a lot of sense. She couldn't argue with the idea that she could use her abilities to stop criminals and protect the innocent. And the thought of being a real-life superhero, inspiring others with her actions, filled her with excitement.

With a newfound sense of purpose, Lily agreed to work with the symbiote, and the two of them merged even more deeply. Lily's mood improved immediately, and she felt a tingling sensation as tendrils sprang out of her body. She used them as extra hands to effortlessly undress herself, allowing some of them to slither over her naked skin, massaging her. One of the tendrils transformed into a phallus, and Lily eagerly took it into her hand. She began to stroke it, feeling the pleasure coursing through her veins. She closed her eyes and let out a gasp as she felt the symbiotic dildo enter her, deeper and deeper.

She could feel the symbiote's presence inside of her, and she reveled in the feeling of being one with it. She felt more powerful and more alive than she ever had before, and she knew that she was ready to take on the world as a superhero. She was ready to use her abilities to protect the innocent and stop the evil that threatened her city.

As the tendrils continued to massage her, Lily felt her body becoming more and more aroused. She let out a moan of pleasure and threw her head back, surrendering herself completely to the symbiote. She was ready to embrace her new identity as a superhero and take on the world with her newfound powers.
