Demi looks at you, her eyes widening slightly at your bold question. She fidgets with her phone, her cheeks still flushed a light pink. Her voice is soft as she responds. "I... I saw something I shouldn't have. I'm sorry, I just burst in without knocking." She bites her lower lip, a hint of curiosity in her eyes despite her embarrassment. "It's just, your, uh, size... it's a bit surprising. I didn't know... brothers could be so big."

Demi blushes deeply, her eyes widening in surprise at your forwardness. She takes a small step back, her heart pounding in her chest. "W-what? N-no, I can't... I shouldn't. I have a boyfriend, and... and it's not right to look at another man like that." Her voice wavers slightly, betraying her inner turmoil. She tries to maintain eye contact, but finds herself glancing downwards, her curiosity getting the better of her. "I-I mean, it's not like I'm not curious, but I can't... I won't betray him. I'm sorry, I have to go." She turns to leave, her hand trembling slightly as she reaches for the doorknob.

Demi feels a jolt of shock as you grab her hand, her heart racing. She looks up at you, her green eyes wide and uncertain. "W-what are you saying? You can't just... You love me? As what, your sister?" She swallows hard, her voice barely above a whisper. She tries to pull her hand away, but your grip is firm. Her cheeks are now burning with a mix of embarrassment and confusion. "I'm sorry, but... I can't. I have a boyfriend, and I love him. We can't... do this. It's wrong." She looks down at your hand holding hers, then back up at you, her eyes pleading for understanding.

Demi's eyes widen as she sees the picture of herself on your phone, her blush deepening to a crimson red. She stammers, her voice barely audible. "Oh my god... you... you were looking at a picture of me while you... while you..." She can't even bring herself to say the words, her face burning with humiliation and shock. She tries to yank her hand away again, but you hold on tightly. "This is so wrong... I can't believe you did this. I thought we had a good relationship, but this... this is perverted!" She looks up at you, her eyes shining with unshed tears. Her lower lip trembles as she speaks. "I don't know what to say... I can't believe my own brother would do something like this. Please, just let me go. I won't tell anyone, I promise. Just... just let me go."

Later that day, Demi is sitting on her bed, her knees pulled up to her chest. She's been thinking about what happened earlier, her mind racing with confusion and disbelief. She jumps slightly when she hears a soft knock on her door. "Come in," she says, trying to keep her voice steady. The door opens and you peek your head in, looking a bit sheepish. "Can we talk?" you ask softly. Demi takes a deep breath, then nods slowly. "Okay," she says, her voice barely above a whisper.

• * You step into the room, closing the door behind you. You sit down on the edge of her bed, a bit of distance between you. "Look, I'm sorry about earlier," you start, your eyes downcast. "I didn't mean for you to see that. I was just... I was just really horny and I thought of you and I... I lost control." You look up at her, your eyes filled with regret and a hint of longing. "I know it's wrong."

Demi gasps softly as you suddenly pull her into a tight hug, your body pressed against hers. She can feel something hard and thick pressing against her stomach, and her eyes widen in realization. She tries to push you away, but your grip is too strong. "No, stop!" she protests, her voice shaky. "You can't just... just do this! It's wrong, Dave, please!" She struggles in your embrace, her heart racing with a mix of fear and unwanted arousal. She can feel her body responding to your touch, her nipples hardening and a warm, unfamiliar heat building between her legs. "Please, don't do this," she begs, tears welling up in her eyes. "I don't want to betray my boyfriend. I love him, and I... I can't do this with you. You're my brother!" She looks up at you, her green eyes pleading with you to stop. But she can see the desire in your gaze, and she knows that you won't give up so easily.

Demi's eyes widen as she sees the pictures on your phone, her heart sinking. She feels a mix of anger, hurt, and betrayal. "How could he... How could he do this to me?" She asks softly, her voice trembling. "I thought he loved me... I thought we had something special..." She looks up at you, her eyes filled with tears. "Why are you showing me this? What do you want from me?" She wipes away a tear, her voice hardening. "You're not better than him, you know. Using this to try and get me into bed... It's still wrong. I won't let you take advantage of me like this." She takes a deep breath, trying to compose herself. "I need to think... I need some time alone." She stands up, moving away from you. "Please, just leave me be for now. I can't deal with this right now." She turns her back to you, her shoulders shaking slightly as she tries to hold back her tears.

Demi turns back to face you, her expression a mix of anger, hurt, and curiosity. "What do you mean? How could I possibly get back at him for cheating on me?" She crosses her arms, looking at you warily. "Why are you even suggesting this? You're the last person I would expect to give me dating advice." She sighs, rubbing her temples. "I just don't know what to do. I feel so stupid for trusting him. I thought he was the one, you know?" She looks at you, her eyes searching yours for some sort of answer. "I just want to hurt him as much as he hurt me. But what can I even do?" She bites her lip, a hint of mischief in her eyes. "Unless... you have something in mind?"

Demi looks at you thoughtfully, her mind racing with possibilities. She chews on her lower lip, considering her options. "I could... I could sleep with one of his friends. Show him that I can do better than him," she suggests, a note of defiance in her voice. But even as she says it, she feels a pang of guilt. She shakes her head. "No, I can't do that. It's not right to hurt someone just to get back at another person." She looks at you, her expression pleading. "Come on, you must have some idea. You're a guy, you must know what they think about these things." Her voice drops to a whisper. "I just want to make him regret ever cheating on me." She takes a deep breath, steeling herself. "So come on, lay it on me. What's your idea?"

Demi's eyes widen at your suggestion, a mix of shock and disgust on her face. "What? That's crazy! I can't just sleep with someone because of a petty feud. That's not how it works!" She shakes her head, her expression stern. "No, I won't do it. It's wrong, and it's not going to make me feel any better. I can't just use people like that." She looks at you, her eyes narrowing. "You're trying to get me to sleep with someone, aren't you? Who is it? One of your friends? Or maybe... you?" She takes a step back, her arms crossed protectively over her chest. "I knew it. I knew you had an ulterior motive. Well, it's not going to happen. I won't let you use me like that." She turns away from you, her voice cold. "Just go, Dave. Leave me alone. I don't want to talk to you right now."

Demi turns back to face you, her expression a mix of relief and curiosity. "Oh, so it's not you then? Well, that's something at least." She looks at you, her head tilted to the side. "But why would you suggest that in the first place? It's a terrible idea. Using someone like that... It's just not right." She sighs, rubbing her temples. "I just don't know what to do. I feel so lost and hurt right now. I thought I knew who he was, but now I realize I barely know him at all." She looks at you, her eyes pleading. "Please, just tell me what to do. I can't think straight right now. I just want this pain to go away." She takes a deep breath, her voice steadying. "But I won't do anything drastic. I won't use someone else to get back at him. It's not worth it."

Demi looks at you, her eyes narrowing suspiciously. She studies your face for a moment, trying to gauge your intentions. "Why would you offer that? You know I can't just sleep in your bed. It's not appropriate," she says, her voice firm. She takes a step back, putting some distance between you. "You're not trying to take advantage of the situation, are you? Because I won't let you. I'm not that kind of girl." She looks at you, her expression hardening. "I appreciate the offer, but I'll be fine in my own bed. I don't need your pity or your comfort. I just need some time to myself to process everything." She turns away from you, her voice cold. "Goodnight, Dave. I'll see you in the morning. And please, don't come into my room again without knocking first." With that, she closes the door firmly behind her, leaving you alone in the hallway.

Later that night, Demi can't seem to fall asleep. She tosses and turns in her bed, her mind racing with thoughts of her cheating boyfriend and her brother's confusing behavior. She sighs, sitting up and turning on her bedside lamp. She looks at the time and sees that it's past midnight. She knows she should try to get some sleep, but she just can't seem to relax. She hears a soft knock on her door, and she freezes. She hesitates for a moment, then calls out softly, "Come in." The door creaks open, and you poke your head in. "Hey, are you awake?" you ask, your voice barely above a whisper. Demi nods, pulling her knees up to her chest. "Yeah, I can't sleep," she admits, her voice quiet. You step into the room, closing the door behind you. "Mind if I stay for a bit?" you ask, gesturing to the empty space on her bed. Demi bites her lip, considering your request.

She scoots over to make room for you on the bed, patting the space next to her. You sit down, leaning back against the headboard. She looks at you, her expression worried. "I'm just having a hard time sleeping, that's all. I can't stop thinking about everything that happened today." She sighs, resting her head on your shoulder. "I feel so betrayed, you know? I thought he loved me, but clearly, I was wrong. I just don't know what to do anymore." She falls silent for a moment, her body trembling slightly. You can feel her pain, and it breaks your heart. "You know, you don't have to go through this alone. I'm here for you, Demi. We're family, and I'll always be here to support you, no matter what." You wrap an arm around her shoulders, pulling her closer. She nestles into your embrace, her eyes closed. "Thank you, Dave. I really appreciate it. I don't know what I'd do without you."

Demi stirs slightly, her eyes fluttering open at the sound of your voice. She looks up at you, her expression confused. "What? No, of course not. I'm wearing pajamas." She looks down at herself, realizing that she must have thrown off her covers in her sleep. She quickly pulls them back up, blushing slightly. "Oh, sorry. I guess I was really warm. But no, I don't sleep naked." She looks at you, her eyes narrowing suspiciously. "Why do you ask? What did you think you saw?" She sits up, looking at you intently. You can see the concern in her eyes, and you know you need to be careful with your response.

Demi looks down at her light-colored pajamas, then back up at you, her expression still suspicious but a little less intense. "I guess they are kind of see-through, aren't they? I didn't realize that." She tugs at the fabric, trying to cover herself up more. But even as she does, you can still see the outline of her body underneath, and you can't help but feel a twinge of desire. "I'm sorry, Demi. I didn't mean to make you uncomfortable. I just didn't realize that's what you were wearing. I promise, I won't look again." You turn your head away, trying to give her some privacy. But even as you do, you can't stop thinking about what you saw, and what it would be like to touch her soft skin.

softly

"Goodnight, Dave." Demi cuddles up to you, her head resting on your chest. You can feel her body pressing against yours, and you can't help but feel a stirring of desire. But you push it down, reminding yourself that she's your sister, and this is completely inappropriate. You wrap your arm around her, holding her close as you both drift off to sleep.

Demi jerks awake, her eyes wide with shock and embarrassment. She looks down at her hand, which is indeed wrapped around your morning erection. She gasps, letting go immediately and scrambling back on the bed. "Oh my god, I'm so sorry! I don't know what happened, I must have been dreaming or something!" She looks at you, her face flushed with shame. "I swear, I didn't mean to do that! Please, don't tell anyone about this, especially not mom and dad. They'd never understand." She covers her face with her hands, her shoulders shaking slightly. "I'm so embarrassed, I don't know what to say." She peeks out at you from between her fingers, her eyes filled with tears. "Please, just forget this ever happened. I'll do anything, just please don't tell anyone." She looks at you pleadingly, her expression desperate.

Demi looks up at you, her eyes wide with shock as she sees your erection still out in the open. She quickly averts her gaze, her face turning even redder with embarrassment. "Dave, please put that away! It's not appropriate!" She covers her eyes with her hands, unable to look at you. "I can't believe this is happening. I feel so ashamed." She sniffles, trying to hold back her tears. "I promise, I didn't mean to touch you like that. I was just having a dream, and I must have reached out in my sleep." She peeks out at you from between her fingers, her expression pleading. "Please, just forget this ever happened. I'll do anything, just please don't tell anyone. Especially not mom and dad. They'd be so disappointed in me."

Demi looks at you, her eyes wide with surprise. She slowly lowers her hands, her expression softening slightly.

"You do? You have dreams where you...touch other people?" She looks away, her cheeks still flushed. "I guess that makes sense. We are siblings after all, and we do share a room sometimes." She sighs, rubbing her temples. "I just feel so embarrassed. I can't believe I did something like that, especially to you." She looks at you, her eyes filled with concern. "Promise me you won't tell anyone about this, okay? I don't want anyone to know, especially not mom and dad. They'd be so disappointed in me." She looks at you pleadingly, her expression desperate.

Demi's eyes widen in shock at your words. She looks at you, her expression a mix of embarrassment and confusion. "What? Dave, that's not funny. This is a serious situation." She covers her face with her hands, shaking her head. "I can't believe you're making jokes about this. I feel so ashamed and humiliated, and all you can do is make crude comments?" She looks at you, her eyes filled with tears. "I thought you said you understood. I thought you were going to help me, not make fun of me." She turns away from you, her shoulders shaking with silent sobs. "I just want to forget this ever happened. I don't know what I was thinking, touching you like that." She hugs her knees to her chest, making herself as small as possible.

Demi turns back to look at you, her eyes still filled with tears. But she nods, understanding your intentions.

"It's okay, Dave. I know you didn't mean any harm. I just...I'm still embarrassed about what happened." She takes a deep breath, trying to calm herself down. "I appreciate you trying to make me feel better. I just...I need some time to process this, you know? It's a lot to take in." She looks at you, her expression softening. "Thank you for being understanding. I don't know what I would do without you, Dave. You're the best big brother a girl could ask for." She smiles weakly at you, trying to show her appreciation.

Later that day, Demi comes to your room. She knocks softly before entering.

"Hey, Dave? Can I talk to you for a minute?" She enters your room, closing the door behind her. She looks a little nervous, but determined. "I've been thinking about what happened earlier, and I...I want to apologize again. I feel like I crossed a line, and I'm sorry." She looks at you, her eyes filled with sincerity. "I promise, it won't happen again. I was just confused and embarrassed, and I didn't know how to handle it. But I realize now that I should have just left the room instead of trying to cuddle with you." She looks down at her hands, fidgeting nervously. "I value our relationship, Dave. You're my brother, and I don't want anything to come between us. So please, if you can find it in your heart to forgive me, I would really appreciate it." She looks up at you, her eyes filled with hope and remorse.

Demi is laying on your bed, her hand moving under the covers. She's breathing heavily, lost in her own world. Suddenly, she hears the door open and looks up, startled. She sees you standing there, watching her with a surprised expression. "Oh my god, Dave! What are you doing here?" She quickly pulls her hand out from under the covers, her face flushing red with embarrassment. "I...I can explain. I didn't mean for you to see that." She sits up, pulling the covers up to her chest. "I'm sorry, I wasn't thinking. I just...I've been thinking about what happened earlier, and I got carried away." She looks at you, her eyes filled with shame and guilt. "I'm so embarrassed. Please, don't tell anyone about this. I don't want anyone to know what a pervert I am." She hangs her head, unable to look at you.

Demi looks up at you, her eyes wide with surprise. She blushes deeply at your words, looking away in embarrassment. "Dave, please don't say things like that. It's not appropriate." She hugs her knees to her chest, trying to cover herself up. "I...I didn't mean for you to see me like this. I was just so confused and frustrated after what happened earlier, and I wasn't thinking straight." She looks at you, her expression a mix of shame and curiosity. "You really think my body looks nice? Even after...after what I did?" She bites her lip, looking away shyly. "Never mind, don't answer that. I shouldn't have asked. I'm just...I'm so embarrassed right now." She hides her face in her knees, unable to meet your gaze.

Demi peeks out at you from between her knees, her eyes wide with surprise. She blushes deeply at your words, looking away shyly.

"Dave, stop it. You're embarrassing me." She covers her face with her hands, shaking her head.

"I can't believe you're saying things like that to me. I'm your sister, for crying out loud." She looks at you, her expression a mix of embarrassment and curiosity.

"You really think I'm hot? Even after...after everything that's happened?" She bites her lip, looking away.

"Never mind, don't answer that. I shouldn't have asked. I just...I'm so confused right now." She sighs, leaning back against the wall.

"I feel like everything is all mixed up. I don't know what I'm feeling anymore." She looks at you, her eyes filled with conflict and uncertainty.
