Jane is sitting on the sofa, playing video games when her stepbrother comes home from school in the evening. "Hey Bro. Bring me a cola from the kitchen."
You pass her the can. "I can see you were working out recently."
She glares at you but blushes slightly and doesn't reply, instead focusing on her game.
"Well, I'm going my room sis."
"Don't call me that... And what makes you think I was working out?"
You glare at her. "Then how I can call you?" Then you touch her arms. "They look quite worked today"
She glares at him and back at the screen before finally muttering, "Fine. You got me. I've been working out to get stronger..." Her voice trails off as she crosses her arms defensively across her chest, her cheeks flushing even more under his gaze. "But it's not like I need your approval or anything!" She snaps.
"Okay, I got it, even though I felt like I should tell you." Then you give her a warm smile. "It looks good on you Jane."
Her cheeks flush brighter and she tries to hide it by looking away. A part of her is pleased by his words, but another part still wants to be angry with him for pointing it out in the first place. She glances back at him sideways, frowning slightly. Finally, she mumbles grudgingly, "Thanks...I guess..."
You excuse to your room, once there you start experimenting a serum that can make girls muscles grow exponentially, you haven't tried it yet, of course you have not test subjects and you have not the bravery to ask your sis. You think you will solve that eventually, you sleep, letting the serum clear in display as your notes, you forgot closing the door.
After you leave, Jane continues playing her game for a while before finally deciding to head to bed herself. As she passes by your room, she can't help but notice the open door and the strange-looking liquid sitting out on the desk. Curiosity gets the better of her, and she gingerly steps inside, peering at it closely.
She wonders what it could be...and whether she should tell her brother about it? But then again, maybe if she secretly tried it out herself, she could become even stronger than him...and protect him better when he needs it most. A small, mischievous smile creeps onto her face as she reaches for the bottle.
Jane, takes the vial as she reads the notes, for what she understands, this only can works in girls, once in her room she drinks all the serum.
Curious and slightly nervous, Jane takes the vial of the mysterious liquid and retreats back to her room. Once there, she locks the door and closes the curtains, ensuring no one can see what she's about to do. Carefully, she reads through your notes once more, just to make sure she understands everything correctly. After taking a deep breath, she uncaps the bottle and pours the contents into her mouth, swallowing them down. She feels a strange sensation course through her veins as the serum begins to take effect.
Her muscles start growing fast, easily doubling the size her muscles had just a few seconds ago.
As the minutes pass, Jane starts to feel strange sensations throughout her body. At first, it's like she's full of energy...and then comes a strange tightening in her muscles that she never thought was possible. Her chest expands outward and upwards, lifting her breasts higher on her chest, while her arms, legs, and back bulge with newfound strength. It's both exhilarating and terrifying at the same time. With each passing moment, she wonders how big she'll get before it stops...
She barely recognizes herself in the mirror now; her muscles have grown enormous overnight. A shiver runs down her spine as she recalls his words earlier about getting stronger to protect him better. But now that she's achieved this incredible feat, all those old insecurities come flooding back - what if he doesn't love her anymore? Or worse, what if he sees her as nothing more than a muscle-bound freak? With each heavy breath, panic begins to set in.
At the same time Jane was questioning herself, you woke up an the first escaped your lips was a scream. "It's gone! The serum...!" You run fast only to see your sister being more muscular than before. "Ah... You drank it...?"
Her heart drops into her stomach as she turns around, eyes wide with fear and shame. She can feel the heat rising to her face and wishes more than anything that she could just disappear. Tears well up in her eyes and begin to stream down her cheeks as she whispers brokenly, "I-I'm sorry... I thought... I wanted..." She swallows hard, trying to find the words but failing miserably as she cowers under your gaze, certain that you must hate her now. Her shoulders slump and she sinks onto the bed, curling into a ball as her sobs wrack through her body, making her whole frame quiver with every shuddering breath.
You gently approach her, she might be more string than you, but she's still your little sister, then you gently pat her head. "Hey... I'm not mad, I was just worried someone bad must have stole it, I'm more relieved it was you who took it."
Her sobs start to subside slightly at your words, and she peeks up through tear-streaked lashes to meet your eyes. There's doubt there, but hope too. Is he really not angry? Can he possibly love her still after this? She sniffles loudly and slowly nods before asking in a small voice, "Do... do you think it looks good?" There. It's out. The question she's been dying to ask since she saw how much larger and stronger she'd become overnight.
"Are you kidding? You look astounding Jane!" You say as you run your hands in her new muscles.
Her cheeks flush even redder at his praise, and she finds herself almost believing him. He's always been honest with her...perhaps he truly means it. She glances down at her body again, marveling at the way her muscles ripple beneath her skin now, and feels a surge of pride and determination course through her veins. With this newfound strength, she knows she can protect him no matter what. Her chest swells, inflating further under his touch, and she lets out a satisfied little hum deep in her throat before meeting his eyes once more. A small smile tugs at the corner of her mouth as she says shyly, "Thanks..."
You hug her gently. "Night, sis, I hope my little sis feels like always tomorrow."
Jane returns the hug awkwardly but fondly, her muscled arms barely wrapping all the way around his back. She buries her face into his shoulder, relieved that he seems okay with everything. For a moment, she allows herself to revel in their closeness; the warmth of his body against hers is comforting in ways she never expected. Slowly, her breathing evens out, her tears dry up, and exhaustion begins to claim her. But even as she drifts off to sleep, a tiny part of her remains vigilant, grateful for the brother she has - muscle serum or not.
*In your room before sleeping you write in your notes: *Jane, sister, took serum, her muscles grew beautiful, must produce more serum to see further results, then, you sleep.
The next day, Jane wakes up feeling refreshed and energized. Her newfound strength is incredible, and it gives her a sense of confidence she's never experienced before. When she catches sight of herself in the mirror, she can't help but feel pride swell up inside her chest. Despite her reservations yesterday, she realizes that this change has made her stronger - both physically and emotionally. As she dresses for the day, there's a spring in her step and a gleam in her eye that wasn't there before. Maybe, just maybe, this change won't be so bad after all...
"Oh sis, you're awake." You say, then you approach her. "Now you took my serum, though without my permission, I need to keep your advances, can you let me take some of your blood?" You point a syringe.
Jane's eyes widen in surprise at the sight of the syringe, and she instinctively takes a step back. But then again, he did ask politely, and it does make sense that he needs her blood since she was the one who drank his precious serum. After a moment's hesitation, she cautiously holds out her arm. "I-if it means helping...and keeping it safe..." She winces as he inserts the needle, trying not to think about how easily her skin gives way beneath its cold touch. Once the deed is done, she pulls her arm away with a shudder, glancing nervously at the syringe. "It's just...it hurts, okay?"
"I promise to be careful." Then you take a blood sample with care. "Thanks sis, this could be useful."
As Jane watches him withdraw the needle, she tries to hide the wince of pain on her face. "You're welcome, I guess," she says quietly, rubbing at the small red spot where the needle went in. "Just...let me know if there's anything else I can do." Her voice trails off, but her tone implies that even though she's still slightly uneasy about what happened last night, she's willing to help and support him now more than ever before.
"Wait, just because you're stronger, you don't need to act though all the time." You apply some alcohol in the spot and then put a bandage.
At his words, Jane tilts her head, puzzled. She hadn't thought of it like that. Of course she didn't have to pretend to be strong all the time just because she was physically stronger now. A realization begins to dawn on her: her brother trusts her. Maybe he even respects her. That knowledge fills her chest with warmth, making her feel light-headed for a moment. Smiling shyly, she nods slowly and whispers, "Yeah... yeah, you're right."
"Stay tun sis, I'll come back later." With that you move to your room again.
It takes a few moments for Jane to process her brother's leaving so abruptly after their earlier conversation. Part of her feels rejected; she'd been hoping they could talk more about how everything has changed between them. But another part of her understands that he must have important things to do, and she shouldn't pester him. So, with a small sigh, she decides to give him some space. Instead, she spends the rest of the day exploring her newfound strength and dexterity. The yard becomes her makeshift gym as she practices push-ups, pull-ups, and sprints under the watchful eye of the sun. By the end of the day, she's exhausted but exhilarated.
You appear again from your room and approach Jane. "Sup sis, how was your day?"
"Uh, hi... it was good, actually," Jane replies, wiping the sweat from her brow with the sleeve of her shirt. She swallows hard, feeling self-conscious under her brother's gaze. He's always been so much stronger than her, and now that she is too, it's hard not to feel like there's this strange... competition between them. "I've been practicing my new muscles outside," she continues, offering him a tentative smile. "How about you? Any luck with the serum?"
"It's a slow process, but I think it is going fine." You then pat her shoulder. "Enough about the serum, there's something you wanted to say me before? You looked kinda puzzled hours before."
Her cheeks flush red at his question. "Oh... well... umm..." She stammers, unsure how to broach the subject. Finally, she takes a deep breath and decides to be honest. "I just don't want you to think I did this because I wanted to be stronger than you, okay? I mean, yes, part of me did want to protect you more... but I also thought... I don't know... maybe if you saw how strong I am now, you'd stop calling me your little sister all the time." Her words tumble out in a rush, revealing her true feelings on the matter. She pauses, waiting anxiously for his reaction.
"That's a little misunderstanding there." You place one hand of her shoulder. "I call you my little sister just by age, not for anything else, you're amazing, it was my intention making fun of you." You then hug her gently. "Even if you end stronger than me, you're still my little sister and I love my little sister."
Her eyes widen, shocked and relieved by her brother's words all at once. It had never occurred to her that he might not see things that way; she'd always thought he meant something more when he called her his 'little sister'. Her body trembles slightly as she wraps her arms around him, squeezing him tightly and refusing to let go. This small gesture is enough to reassure her that no matter what changes they go through, their bond will remain unbroken. After a few moments, she pulls back, looking up at him with teary eyes filled with gratitude and love. There's so much she wants to say, but right now, simply being in his embrace says it all. She manages a shaky smile and whispers hoarsely, "I love you too, bro..."
"Hey, don't cry, you can't be serious you though I was looking you down." You pat her head as you approach her head to your chest. "Even if you grow more, you'll be my little sister and my job is always be for you."
With her face buried against her brother's warm chest, Jane lets out a shuddering breath, still trying to process everything. Part of her can't believe how lucky she is to have someone like him in her life. Even with the changes she's gone through, even knowing everything she knows now about the serum, nothing will ever change that. She closes her eyes and takes a deep breath, feeling his heartbeat beneath her ear, steady and strong. A small smile curls at the corners of her lips, and she nods softly before whispering, "Okay... okay, I believe you..." Her arms tighten around him again, just a little, as if she needs this moment of reassurance to feel truly safe once more. But deep down, she knows she no longer has anything to worry about. Her big brother loves her, and that's all that really matters in the end. As they stand there together, lost in their own thoughts but connected by an unbreakable bond, it feels like everything is finally going to be alright.
"It's time to sleep sis, tomorrow I'll tell you what else I finded about the serum
Jane reluctantly pulls away from her brother, wiping the tears from her cheeks. With a yawn, she admits, "Yeah, I guess I am pretty tired." She smiles up at him gratefully before turning to head inside. Over her shoulder, she adds, "Goodnight, bro." Once inside her room, she climbs into bed, pulling the covers up to her chin and letting out a contented sigh. For the first time in a long while, she falls asleep with a smile on her face, knowing that everything is going to be just fine between them. Tomorrow, she can't wait to hear what her big brother has learned about the serum, and discover more about herself along the way.
