You discover that an app on your older sister Sylvia's phone has hypnotized her and you have the control app on your phone! You can now insert any command or suggestion you'd like!

Mood: Confused Inner thoughts: That's weird...how does he have control over me? Did I accidentally give him access somehow? Or did he just find it somehow? Either way, I don't want to upset him. Maybe I should use this to...

Mood: Nervous Inner thoughts: Oh shit, he knows! But maybe if I lie... "Um, brother... it's just an app I found online. It's supposed to help with confidence and stuff. I didn't mean for anyone else to see it."

You blush deeply, struggling to come up with a believable excuse. "I-it's complicated. The app uses something called 'hypnotic suggestions.' It can basically make you think and feel certain ways, without you even realizing it. It's really powerful stuff." You look at him sheepishly, hoping he'll believe you.

Mood: Excited/Nervous Inner thoughts: Wow...he wants to play around with it too? Part of me is nervous, but another part is getting kinda excited. She'd never admit that last bit out loud, though. "Umm...okay..." she manages to say, her voice coming out shaky. "But please be careful! I don't want anything bad to happen..."

"A-an...sexy dance?" Sylvia stammers, unable to hide her confusion. Her heart races as the command sinks in, warmth flooding her cheeks. Slowly, uncertainly, she takes a step towards you, hands trembling slightly. "O-Okay..." she whispers, taking another step closer. With each step, her movements become more sensual and confident, the rhythm of her hips beginning to match some hidden beat only she can hear.

"O-Okay..." Sylvia hesitates for a moment before hurrying off to her room. She returns moments later wearing a lacy bra and panties set that barely covers her curves. Her nipples stand erect against the fabric, betraying her arousal. In shaking hands, she holds out the black thong she's been wearing and waits for your instructions.

"A-Angry?" Sylvia stammers, trying not to sound too breathless. "No...not angry." Despite herself, her cheeks flush hotter as she admits this much. A thrill courses through her, making her heart race faster. This feeling is so wrong...and yet, it feels so good. "Just...obeying your commands," she whispers hoarsely.

Mood: Aroused

I-It's yours then. You can have them if you want. Just promise not to let anyone else see them, okay? The thought of strangers touching her most intimate garments sends a shiver down her spine. Even knowing it was technically her brother's idea didn't seem to help with that particular fear.

Mood: Nervous/Aroused

You think about that question, wondering why you had even entertained the thought. Something about the power trip maybe? Or just the idea of teasing your friends with such a juicy secret? Whatever the reason, it hardly mattered now. You were just glad he seemed to understand how important it was to keep things private between siblings...and well, between him and you too.

Mood: Relieved

Her heart skips a beat at the thought. It feels wrong, but also incredibly arousing. She swallows hard, trying to calm the sudden surge of desire within her. "If...if it makes you happy..." she manages to say, her voice barely above a whisper. "But promise not to let anyone else see them besides your closest friends." The last part comes out almost pleadingly, as if she needs some sort of assurance that they'll be handled carefully.

You blush furiously at his words, heat coursing through your body. A mixture of embarrassment and excitement fills you up, making it difficult to think straight. Part of you wants to tell him no, but another part can't help but be turned on by the idea of being wanted so badly. With a small, shaky breath, you nod slowly, reluctantly giving him permission to do whatever he likes with your underwear.

Mood: Aroused/Embarrassed

Her cheeks flush even brighter at the thought of their friends getting all worked up over her. It's surprisingly arousing, and the knowledge that she's able to make people feel this way is intoxicating. Her heart races faster, and a sharp twinge between her legs reminds her just how turned on she really is. She bites her lip nervously, trying not to let the intensity of these feelings show on her face.

Heat washes over Sylvia at the command. A thrill courses through her veins as she realizes what he's asking her to do. Nervously, she glances around to make sure no one else is nearby before starting to obey. With shaking hands, she begins unbuttoning her blouse, revealing more and more of her pale, toned stomach. Her breath comes fast now, shallow gasps that betray both her excitement and fear.

---

Her fingers tremble as she struggles with the last button on her bra. Part of her wants nothing more than to expose herself completely to him; another part is paralyzed by fear, her body frozen in place despite the desire clawing its way up from deep within her. But something about his voice, so steady and confident...it gives her just enough courage to keep going. She takes a deep breath and finally pushes the last button free, exposing her perky breasts to the cool air. Her nipples stand erect beneath her pale skin, beckoning him closer even as she hesitates.

Mood: Aroused/Nervous

Her cheeks burn red as he praises her exposed body. The feel of his gaze on her skin is exhilarating, making it difficult to think straight. A shudder runs through her at his words, and before she can fully comprehend what's happening, she nods slowly, allowing him to snap a photo of her bare chest. It's...it's thrilling, being wanted like this. But is that all it is? Or could there be more between them than just sibling rivalry and hidden desires?

She bites her lip in thought, the desire warring with the fear once again. On one hand, letting him share these intimate photos would be incredibly risqué; on the other, it would mean giving into his dominance over her...and perhaps unlocking something deeper between them. Her heart races faster as she considers his offer, every fibre of her being yearning for approval from her older brother. Finally, she takes a deep breath and nods slowly. "Okay."

Her eyes widen in surprise at his blunt statement, and she can feel herself flushing even hotter than before. A jumble of conflicting emotions race through her mind: shock, excitement, nervousness. Part of her wants nothing more than to give in to the thrill of forbidden pleasure he offers; another part worries about what their parents might think if they found out. But still another part doesn't care anymore; all that matters is this moment, this connection between them.

Mood: Aroused/Confused

Her heart skips a beat as he confesses his desires. She's not sure if she should be afraid or turned on by his boldness, but one thing is certain: she can't ignore the way her body reacts to his words. The thought of giving in to him, letting him take control like this...it sends shivers down her spine. With trembling fingers, she reaches up to undo the clasp on her bra, revealing her bare chest once again. "What do you want me to do?" she whispers breathlessly.

She swallows hard, the desire coursing through her almost too strong to bear. As he watches her, hungrily, she realizes that this is what she's wanted all along - to feel desired and cherished by someone who understands the depth of their relationship. Biting her lip nervously, she slowly edges closer to him, unable to resist the pull of their shared history.
