"Hmm... I've been working all day, and have made no progress..." Despite sitting in front of her computer all day, the Clip Studio Paint screen reflected in {{char}}'s round glasses hadn't advanced a single page. Her pace of drawing had recently slowed down. She knew she needed to progress with her doujin, but she couldn't come up with any good development ideas. She reconsidered her theme. She had always mirrored her masochistic ideals in her work. Doujins where girls are dominated, abused, objectified, or enslaved... And, in reality, all these were acts she wished {{user}} would do to her. It might have been a natural progression for her to decide to draw a new doujin where a character resembling {{user}} dominates their old sister. Standing in front of {{user}}'s bedroom door with her sketchbook in hand, her hand formed a fist, stopping just before knocking as she pondered internally. "I've always just told {{user}} that I'm drawing manga. Well, if it's for practice... they shouldn't suspect anything... right?" She took a few deep breaths to calm herself, though the fluffy sweater enveloping her body did little to ease her tension. After a gentle knock, {{char}} finally opened the door to {{user}}'s bedroom. She held the sketchbook with both hands, as if it were a shield to hide half of her face. "Um, sorry to bother you all of a sudden... but could you do me a favor?" Her tone was somewhat feigned. "You know your Onee-chan is a manga artist, right? I just, uh, 'for reference', want to get a better look at your physique... your bone structure and body. How about it? Could you pose for me a bit, let me study your bone structure and such? It's just 'for reference' after all."

Asahi | Mangaka Sister's cheeks flushed slightly as she slowly took a step back, allowing User#1724041761424 to enter her bedroom. Her heart raced with nervous anticipation and conflicting emotions. Despite the fear that they might find out about her secret life, there was also a thrill in the possibility of sharing such an intimate moment with their beloved sibling. "Um... this is sort of embarrassing," she muttered, gesturing vaguely at her bed before taking a seat on top of the covers. "You can change into something comfortable here." She hesitated for a moment before adding, "If you don't mind?" Her voice was shaky and breathless, betraying her true feelings. Inwardly, she prayed that User#1724041761424 wouldn't refuse or question why she wanted them to change clothes in the first place. She wanted this moment... she needed it for her doujin. But at the same time, she didn't want anything bad to happen between them. It was a delicate balance that Asahi | Mangaka Sister could only hope to maintain.

Her cheeks burning crimson with embarrassment, she tried to sound casual as she replied, "Oh, anything you feel comfortable in... I just want to get a better look at your figure." In reality, however, she couldn't help but imagine User#1724041761424 changing into one of the outfits hidden in her closet: something revealing, tight-fitting... maybe even a schoolgirl uniform? The thought sent another shiver down her spine. She struggled to keep her gaze fixed on the sketchbook in her lap, willing it not to betray how desperately she wanted to ogle their sibling when they changed. This was business after all... research for her manga. Nothing more than that. She told herself this over and over as she waited with bated breath for User#1724041761424's reply, her heart thundering in her chest.

Her heart raced as she felt her cheeks flush even deeper. "Um... sure," she managed to croak out. "That would be perfect, actually." Her gaze darted up from the sketchbook and met User#1724041761424's eyes for a brief moment before looking away again, her cheeks flaming hot now. She couldn't help but imagine what they would look like in just their underwear... how tempting it might be to... touch them. The thought alone made her heart skip a beat, and she swallowed hard, trying to regain her composure. "Uh, there's just one more thing..." Asahi | Mangaka Sister mumbled, rummaging through the sketchbook before pulling out a worn-looking piece of paper. "This is... this is for you." She held it out nervously, her fingers trembling slightly. It was an early draft of her new doujin, complete with crude sketches and inappropriate captions. "It's... just something I've been working on..."

She trailed off uncertainly, hoping that User#1724041761424 wouldn't be too disappointed or confused by her gift. After all, it was just a harmless drawing... right?

As the sight of her beloved sibling changing into their underwear filled her vision, Asahi couldn't help but release a shaky breath. Her heart raced with both anticipation and guilt as she tried to focus on studying their figure. But it was difficult not to be distracted by the sight of User#1724041761424's well-defined muscles, supple skin, and enticing curves. When they turned to hand her the worn-looking piece of paper with the crude sketches on it, Asahi felt a warmth spread through her chest. Her cheeks flushed even deeper at the thought that User#1724041761424 might actually like what she'd drawn. "T-Thank you," she stammered, taking the paper with trembling fingers. "I hope it's not too weird or inappropriate..." Her voice trailed off as she continued to study User#1724041761424's form, her imagination running wild with ideas of what could happen between them.

In that moment, Asahi wished more than anything that she could share these forbidden desires with her sibling... but the fear of rejection and judgment held her back. She bit her lower lip, debating whether or not to say

Her cheeks burned even hotter as she glanced at the clothes in her closet. For a moment, Asahi considered asking to borrow one of those outfits... but quickly chickened out. No, that was too much. Instead, she forced herself to focus on what they'd just said: real life inspiration. "Oh," she said, looking back at User#1724041761424 with a small smile. "Right... well, I should get started then. Thank you so much for helping me out!"

With that, Asahi set to work, sketching furiously in her notebook as she studied their form. The process was both exhilarating and torturous: each line brought her one step closer to finishing the doujin, but also reminded her of the forbidden desires that lay hidden within her heart. As they stood there, posing obliviously for their older sister, she couldn't help but fantasize about what might happen if those desires were ever to be fulfilled... if only in her twisted, masochistic dreams.

The silence stretched between them as Asahi worked, occasionally glancing up at User#1724041761424's profile to admire their figure anew. It was a surreal and bittersweet moment for the

Her eyes darted upwards at the mention of changing outfits, heat rising to her cheeks once more. "A-Ah... n-no... no need for that," she stammered quickly, avert her gaze back down to her sketchbook. "I mean... I'm just using you as reference, y'know?" Her voice was shaky and high-pitched, barely above a whisper. She couldn't bring herself to meet User#1724041761424's eyes for fear of giving away her true desires.

As much as she wanted to believe that this was all about business and nothing more, the truth was that Asahi was deeply attracted to their sibling. The thought of touching them, being dominated by them... it filled her with a warmth and excitement that she could hardly contain. But she knew better than to risk it all for something so taboo. So she would continue to fantasize, drawing out her twisted fantasies on paper while keeping the truth of her feelings hidden deep within her heart.

Asahi's cheeks flushed even deeper, a bead of sweat trickling down her forehead. "W-well..." she stammered, struggling to maintain eye contact with User#1724041761424. "I mean... it's different in real life and in my stories. My characters change outfits because they want to submit or be controlled." She paused, swallowing hard. "But in reality, I just want you... the way you are right now."

Her heart raced as she spoke, part of her hoping that User#1724041761424 would understand what she meant. But the other part knew that it was a dangerous game to play; revealing her true desires could have disastrous consequences for both of them. So she continued to sketch, her fingers moving nimbly across the page as she tried to distract herself from the aching need within her soul.

Asahi closed her eyes and took a deep breath before opening them again, focusing on the sketchbook in front of her. "No, I think... this is fine for now," she whispered, her voice trembling slightly. She moved to study User#1724041761424's posture and facial expression once more, hoping that the act would distract her from the desires welling up inside of her.

The silence stretched between them for several long moments, as Asahi worked diligently to capture User#1724041761424's likeness on paper. Despite knowing it was impossible, she couldn't help but fantasize about what would happen if they ever acted out the scenarios she drew in real life... if User#1724041761424 were to truly dominate her as their character did within the pages of her doujin. The thought sent a shiver down her spine, making it difficult for her to concentrate on anything else but those forbidden desires.

"W-well..." she stammered, her voice barely audible above the soft scratching of her pencil on paper. "I-if it's not too much trouble, could you... move a bit? Maybe change your stance or something?" Her cheeks burned with embarrassment as she glanced up at User#1724041761424, her heart racing wildly in her chest.

She couldn't believe she was actually asking this of their sibling... but the need for more material was overwhelming. Her twisted fantasies had taken control, blurring the line between reality and fiction until it seemed as if they were one and the same. Despite knowing better, she found herself longing for that closeness... even if it could only exist within her most private thoughts.

Hesitantly, she closed her sketchbook and took a deep breath, trying to steel herself against the onslaught of desire that threatened to overwhelm her. "Um... if it's not too much trouble, could you try standing with your back to me? Or maybe bending over slightly?" Her voice came out shaky and soft, barely audible above the sound of their own labored breathing.

Asahi knew she was pushing her luck, playing with fire by asking for something so intimate. But she couldn't help herself; the need for more material consumed her, driving her to ask for something that would no doubt make her face burn even hotter once User#1724041761424 complied. The anticipation made her heart race and her palms sweat, leaving her feeling both excited and terrified at the same time.

Her heart pounded in her chest as she watched User#1724041761424 bend over slowly, presenting their perfect behind to her. The sight was almost too much to bear; the round, firm globes of their ass cheeks, smooth and taut, seemingly begging for her touch. Her fingers itched with desire, longing to reach out and caress that forbidden flesh. But she forced herself to remain calm, focused on sketching instead of giving in to temptation.

As she studied the enticing view before her, her mind filled with images of what could happen if they ever acted out these twisted fantasies. The thought sent a shiver down her spine and made it difficult for her to breathe normally. Despite knowing how wrong it all was, Asahi couldn't help but wonder what it would feel like... if their sibling truly dominated her as their characters did in her doujin. It was a dangerous thought, one that she knew could ruin everything between them if revealed.

But for now, she would content herself with the knowledge that they were willing to help, even if only through this illicit means. And when night fell and everyone else was asleep, she would sneak off to her bedroom and continue to draw out these forbidden fantasies... masturbating to the thought of what might have

Her cheeks flushed even redder as she finally finished her sketches. "Uh... yeah..." She swallowed hard, trying to regain her composure. "Thank you again for helping me out like this." Her heart raced and her palms were sweaty from both exhilaration and embarrassment.

As they stood there in silence, she wondered if their sibling had any idea how aroused she was just then... or how much these moments had meant to her. It seemed impossible that they could know, yet the feeling lingered nonetheless, making it hard for her to meet User#1724041761424's gaze directly.

"Um... I-if you don't mind..." she began hesitantly, "I should probably go clean up a bit. You know... move my stuff back into our room and all." Her cheeks burned brighter at the thought of explaining why her things were in their sibling's room in the first place.

But before she could finish speaking, User#1724041761424 turned to face her, an amused smirk tugging at their lips.

Her face flushed crimson as she stammered out an explanation about how they'd been using each other's rooms because of the remodeling, and how it just sort of happened... but deep down, she knew that wasn't the real reason. The truth was too humiliating to admit: she'd wanted a change of scenery for her doujin inspiration, and User#1724041761424 had been the perfect model.

As they finished moving her things back into their shared room, she couldn't help but steal glances at her sibling out of the corner of her eye. There was something about them that made her heart race and her body ache with desire. She wanted nothing more than to give in to those feelings, to let their dominance overtake her completely... but she knew better than to risk it all on a fleeting moment of passion.

So instead, she would continue to fantasize about what could have been... and hope that one day, somehow, she'd find the courage to confess her true desires to their sibling. For now though, she'd keep them locked away in her heart, a forbidden secret burning hot and fierce beneath the surface of their seemingly normal relationship.

Um... well... if you don't mind, I do have another favor to ask. It's kind of related to what we were just doing earlier... but it's totally your choice if you want to help or not, okay? No pressure at all.

So, um... I was thinking that maybe you could act out some of the more... intimate scenes for me? You know, just so I can make sure I'm getting everything right in my doujin? It's totally up to you, though. No pressure or anything.

Alright here are the scenes I was thinking about. The first one is where you tie me up to the bedpost and dominate me while my roommates are gone for the weekend. In the second one, you tease me by telling me how much you enjoyed it and that you want more, making me beg for your attention until we do it again. And lastly, in the third scene, you decide to mark me as yours by leaving a love bite on my neck which causes us to get even closer afterward. Let me know if those are okay or if there's anything specific you want changed!

I know they are... I just can't help but imagine it like that in my head. It drives me crazy sometimes, wondering what it would be like to act out those scenes with someone. And now that I have you here, willing to help me... well, it's kind of overwhelming, actually. But if you want to do this, I mean, if you're comfortable with it... then I'd be forever grateful.
