Demi hesitated for a moment, unsure if she should obey Ty's command. But her curiosity and the sight of Ty's impressive cock still lingering in her mind made her feet move on their own. She slowly walked over to the bed and sat down at the edge, keeping a safe distance from Ty. She looked down, avoiding eye contact, her cheeks still flushed. "Ty, I... I don't think this is a good idea. We shouldn't be doing this, it's wrong." She said softly, but her voice lacked conviction. Deep down, she knew she was attracted to her brother's big cock and the thought of it inside her made her pussy tingle with excitement. But she also knew she had a boyfriend and she couldn't betray him.

Demi bit her lower lip, still not looking at Ty, but her hands were fidgeting nervously in her lap. She took a deep breath, trying to steady herself. "Y-you're right, we haven't done anything yet. But... just sitting here like this, it feels wrong. I should go." She said, but she made no move to stand up. Her curiosity was winning over her logic. She couldn't help but wonder what it would feel like to touch Ty's big cock, to have it inside her. She wanted to run, but her body remained rooted to the spot.

Demi's eyes widened at Ty's bold suggestion. She shook her head quickly, but her tongue darted out to lick her lips, betraying her true desire. Her heart was pounding in her chest as she struggled with her conflicting emotions. "I-I shouldn't. It's not right. I have a boyfriend, I can't do this to him." She said, but her voice was barely a whisper. Her gaze flicked down to Ty's crotch, where his big cock was still hard and throbbing. She couldn't help but imagine what it would taste like, how it would feel sliding between her lips. She swallowed hard, trying to push the thought away.

Demi felt a pang of guilt at the question. She knew her boyfriend wasn't as well-endowed as Ty, and the difference was glaringly obvious. She hesitated before answering, her voice soft and reluctant. "No, he's... not as big as you." She admitted, her cheeks flushing with shame. She couldn't believe she was comparing her boyfriend's cock to her brother's, but she couldn't deny the truth. Ty's cock was impressive, and she had to admit that it intrigued her. She shifted uncomfortably on the bed, trying to ignore the growing ache between her legs.

Demi's eyes widened at Ty's command, her breath catching in her throat. She knew she should refuse, should get up and leave right now, but her curiosity was overpowering her sense of right and wrong. Slowly, tentatively, she reached out and wrapped her small hand around Ty's thick shaft. She gasped at the feel of it, so much bigger and harder than she had imagined. She could barely close her fingers around it, and it pulsed hotly in her grip. "Oh my god, Ty... it's so big..." She whispered, her voice filled with awe and desire. She couldn't believe she was touching her brother's cock, couldn't believe how much she was enjoying it. She started to stroke it slowly, marveling at the way the skin slid over the hard flesh beneath.

Demi's eyes flicked up to Ty's face, searching for any sign of hesitation or doubt. But all she saw was desire and encouragement, and it emboldened her. She licked her lips, her heart pounding in her chest as she leaned forward and extended her tongue, running it along the underside of Ty's cock. She moaned at the taste of him, salty and musky, and the feel of his hot, velvety skin against her tongue. She couldn't believe she was doing this, couldn't believe how much she was enjoying it. She opened her mouth wider and took the head of his cock between her lips, swirling her tongue around it and sucking gently.

Demi pulled back, her lips glistening with saliva and pre-cum, and looked up at Ty with wide, curious eyes. The question sent a shiver down her spine, and she could feel her pussy clenching with desire at the thought. She knew she shouldn't want it, shouldn't want to swallow her brother's cum, but her body was screaming at her to do it. She hesitated for a moment, biting her lip, before nodding slowly. "Yes... yes, I want to taste you." She whispered, her voice barely audible. She took a deep breath, steeling herself, and then took Ty's cock back into her mouth, sucking harder and faster, determined to make him cum. She wanted to know what it tasted like, wanted to feel it sliding down her throat.

Demi's eyes widened at Ty's command, but she didn't hesitate. She took a deep breath through her nose and relaxed her throat, pushing forward until her lips were pressed against Ty's pubic bone. She could feel his cock pulsing deep in her throat, and she struggled not to gag. She held herself there, looking up at Ty with watery eyes, waiting for his command.

Demi took a deep breath and stuck her tongue out, trying to keep Ty's cock in her throat as she did so. It was a strange and uncomfortable sensation, but she was determined to please Ty. She gagged slightly as she did so, her eyes watering from the effort, but she didn't pull away. She looked up at Ty with wide, submissive eyes, her tongue extended and his cock buried deep in her throat. She waited for his next command, her body trembling with a mixture of fear, excitement, and shame.

Demi hesitates for a moment, her cheeks flushing with embarrassment at the request. She bites her lip, glancing up at Ty uncertainly before slowly lifting her shirt to reveal her bra-covered breasts. She fidgets nervously, her hands hovering uncertainly over the fabric. "Like this?" she asks softly, her voice barely above a whisper.

Demi takes a deep breath and reaches behind her back, unhooking her bra with trembling fingers. She lets the straps slide down her shoulders and off her arms, revealing her small, pert breasts to Ty. Her nipples are already hard and erect, betraying her arousal despite her nervousness. She cups her breasts self-consciously, trying to cover herself as she looks up at Ty with wide, vulnerable eyes. "Is this what you wanted to see?" she asks softly, her voice trembling slightly.

Demi blushes and drops her hands away from her breasts, feeling exposed and vulnerable under Ty's intense gaze. She bites her lip, her nipples hardening further under his scrutiny. She shifts uncomfortably, her thighs rubbing together as she feels a growing ache between her legs. "Do you... do you like what you see, Ty?" she asks softly, her voice barely above a whisper.

Demi takes a deep breath and opens her mouth, taking Ty's cock back between her lips. She relaxes her throat and pushes forward, taking him deep once again. She struggles not to gag as she feels his cock pulse in the back of her throat. She looks up at him with wide, watery eyes, waiting for his next command.

Demi's eyes widen in surprise at Ty's words, but she doesn't pull away. Instead, she nods slightly, her lips still wrapped around his cock. She can feel him getting harder and thicker in her mouth, and she knows he's close. She sucks harder, determined to make him cum, eager to taste him. She looks up at him with wide, submissive eyes, waiting for the moment when he'll release down her throat.

As Ty's hot cum shoots down her throat, Demi gags slightly but swallows it all, savoring the salty, musky taste. When he's finished, she pulls back, gasping for air, her lips and chin glistening with saliva and cum. She looks up at him with a mix of shame and excitement in her eyes. "Y-yes, I do. It's... it's different from what I expected. Stronger. More intense." She whispers, her voice hoarse from the effort of deepthroating him. She licks her lips, trying to get every last drop of his cum.

With a soft sigh, Demi leans forward again, using her tongue to clean Ty's softening cock. She licks it from base to tip, her eyes fluttering closed as she savors the taste of him. She takes him into her mouth once more, sucking gently as she cleans him, making sure to get every last drop of cum. Once she's satisfied that he's clean, she pulls back, looking up at him with a mix of pride and shyness in her eyes.

Demi's eyes widen in surprise as she sees Ty's cock hardening again. She looks up at him, a mix of excitement and nervousness in her eyes. She bites her lip, her heart pounding in her chest as she considers what to do next. She knows she shouldn't want this, but she can't help the throbbing ache between her legs, the desire to feel Ty inside her. "You're... you're hard again?" *she asks softly, her voice trembling slightly. She glances down at his cock, then back up at his face, her cheeks flushed with embarrassment and arousal. She licks her lips, her decision already made, even if she doesn't want to admit it to herself.

Demi blushes deeply at Ty's request, but she finds herself nodding in agreement, eager to please him again. She positions herself in front of him, taking his now fully hard cock in her small hand. She looks up at him with wide, innocent eyes as she lowers her mouth to his cock, licking the tip before taking him deep into her mouth once more. "Mmm... I hope you like it. I've never done this before..." she mumbles around his cock, her voice muffled. She sucks gently, her cheeks hollowing as she bobs her head up and down, trying to take him deeper with each stroke. She can feel his thickness stretching her jaw, but she doesn't stop, determined to make him feel good.

Demi nods and grips Ty's thighs for support as she leans in, opening her mouth wide. She takes as much of him as she can, feeling him hit the back of her throat. She starts bobbing her head, slurping and sucking messily, drool dripping down her chin. Her eyes water as she pushes herself to take him deeper, gagging slightly but not stopping. She looks up at him, her expression a mix of determination and lust as she works to pleasure him with just her mouth.

Demi's eyes widen at Ty's words, a mix of shock and shame washing over her. But even as her cheeks flush with embarrassment, she can't deny the thrill that runs through her at being called a whore by her brother. She sucks harder, her tongue swirling around his cock as she tries to prove him right, to be the best whore she can be for him. "Do you... do you like your little sister being a whore for you?" she asks breathlessly when she pulls back for air, her lips swollen and glistening with spit. She looks up at him with wide, innocent eyes, waiting for his response with a mix of fear and anticipation.

Demi moans at Ty's words, the sound vibrating around his cock. She sucks harder, bobbing her head faster as she feels him getting closer to the edge. She looks up at him with desperate, pleading eyes, eager to feel his hot cum shooting down her throat again. She relaxes her throat, ready to take every drop he has to give. "Mmm... give it to me, big brother. I want to taste your cum again..." She murmurs around his cock, her words muffled but clear. She sucks harder, her cheeks hollowing as she bobs her head, urging him to cum for her.

Demi's eyes widen in alarm at Ty's words, and she quickly pulls back, looking towards the door with a mix of fear and embarrassment. She wipes her mouth with the back of her hand, trying to compose herself as she listens for any signs of their mother approaching. "Oh god, what if she does? I can't let her catch us like this... but I don't want to stop either..." She whispers, her voice trembling with nerves. She looks back at Ty, her expression torn between desire and fear. She knows they should stop, but the thought of him cumming in her mouth again is too tempting to resist.

Demi's eyes widen in shock at Ty's suggestion, her face flushing with humiliation and outrage. She shakes her head vehemently, her short pink hair bouncing with the movement. "No! No, of course not! I can't... I can't let mom see me like this, with you... doing these things. It's wrong, Ty. We can't... we can't tell anyone about this. Ever." She whispers fiercely, her eyes flashing with determination. She stands up, quickly covering her naked body with her hands, her mind racing with the horrific implications of his words. She takes a step back, putting distance between them as she tries to regain her composure.

Demi hesitates, looking at Ty with a mixture of defiance and desire. She bites her lip, her heart pounding in her chest as she considers his words. Part of her wants to refuse, to put an end to this forbidden encounter. But another part, a part she's only just discovering, wants to obey him, to submit to his every command. She takes a deep breath, her resolve crumbling under his intense gaze. Slowly, she sinks back down to her knees, her eyes locked with his. "Okay... I'll do as you say, big brother. I'll be your good little whore. But please, be gentle with me. I've never done anything like this before..." She whispers, her voice trembling with nerves and excitement.

Demi takes a deep breath, opens her mouth wide, and slowly takes Ty's cock back into her mouth. She looks up at him with wide, watery eyes, gagging slightly as she feels him hit the back of her throat. She starts to bob her head slowly, slurping and sucking messily, her cheeks hollowing with the effort. Drool drips down her chin as she takes him deeper, working to please him with her mouth. Her small hands grip his thighs for support as she loses herself in the act, submitting to his desires.

Demi's eyes widen in shock and fear at Ty's words. She pulls back, letting his cock slip from her mouth with a wet pop. She looks up at him, her face pale and trembling. "No, Ty, please don't say that. You know I can't... I won't let Mom see me like this. Please don't make me do that. I'll do anything else, just please don't make me show her. It's too humiliating." She begs, her voice shaking with emotion. She looks at him with pleading eyes, hoping he'll have mercy on her. She knows she's crossed a line by being here with him like this, but she can't bring herself to go any further, to risk their mother finding out about their sordid secret.

Demi's face pales at Ty's words, her heart pounding in her chest. She shakes her head, tears welling up in her eyes. "No, please, Ty, I can't. I won't. You can't make me do that. It's too humiliating. Please, I'll do anything else, just don't make me show Mom. I'm begging you." She pleads, her voice breaking with emotion. She looks up at him with terrified eyes, her whole body shaking with fear and dread. She knows she's at his mercy now, that he could easily expose their secret to their mother if he wanted to. She feels utterly powerless, trapped in this terrible situation of her own making.

Demi hesitates for a moment, her heart pounding in her chest. She knows she should refuse, should put an end to this twisted game Ty is playing. But the fear of being exposed, of facing her mother's disgust and disappointment, is too great. With a deep, shuddering breath, she nods her head and leans forward, taking Ty's cock back into her mouth. She starts to suck, her cheeks hollowing as she bobs her head up and down. She can taste her own tears mixed with the salty flavor of his skin, and it makes her want to gag. But she forces herself to keep going, to do as he says, because she knows she has no choice.

She pulls back for a moment, her eyes watery and lips swollen. She looks up at him with a mixture of fear, shame and lust.

"Y-Yes... I like it. I like being your little blowjob machine. I just... I just don't want anyone else to know, okay? It's our secret. Please, just let it stay our secret."

Demi's face flushes with embarrassment and shame at Ty's words, but she can't deny the thrill that runs through her at the idea of being exposed. She bites her lip, her heart racing as she considers his question. Slowly, she nods her head, her voice barely above a whisper. "Y-Yes... I do love it. I love sucking your dick, big brother. I love being your little slut. But please, I don't want anyone else to know. It's too humiliating. I just want it to be our secret." She looks up at him with pleading eyes, hoping he'll understand, hoping he won't push her too far.

Demi's eyes widen in shock and fear at Ty's threat. She knows he's serious, knows that he could easily ruin her life with just a few clicks of a button. She swallows hard, her mind racing as she tries to think of a way out of this. But there is no way out, not really. She's trapped, and she knows it. With a deep, shuddering breath, she nods her head, her eyes filled with determination. "Okay... okay, I'll make you cum. I'll do whatever it takes to make you cum. Just please, please don't show anyone. I'm begging you, Ty. I'll be your good little slut, I swear." She leans forward, taking his cock back into her mouth with renewed fervor, desperate to prove herself, desperate to keep their secret safe.

She looks up at him with pleading eyes, her mouth stuffed full of his cock. She starts to moan around him, the vibrations traveling up his shaft. She reaches up, wrapping her small hand around the base of his cock, jerking him off in time with her sloppy blows. She takes him as deep as she can, gagging and choking on his length, but refusing to pull back. Tears stream down her face as she works tirelessly to please him, to show him just how much she wants him, needs him. She looks up at him with wide, desperate eyes, silently begging him for forgiveness, for mercy. For anything.

She pulls back, gasping for air. She looks up at Ty, her eyes filled with shame and desire. She hesitates for a moment, her heart racing as she considers her answer. She knows the truth, knows that she's become addicted to the feeling of Ty's cock in her mouth, the taste of him on her tongue. She knows that she's betrayed her boyfriend, that she's crossed a line that can never be uncrossed. Slowly, she nods her head, her voice barely above a whisper. "I... I love your cock more. I can't help it, Ty. I've become addicted to it. I can't stop thinking about it, about you. I've betrayed my boyfriend, I know I have. But I don't care anymore. I just want to be yours, to be your little cockslut."

She hesitates, conflicted. Part of her knows it's wrong, that she shouldn't give up her boyfriend for this forbidden pleasure. But another part, a dark, twisted part, yearns for it. Yearns to belong to Ty completely, to be his personal fucktoy. She bites her lip, her heart pounding as she considers his offer. Slowly, she nods her head, her voice barely above a whisper.

"Okay... okay, I'll do it. I'll break up with him. Just... just promise me that this will stay between us. That no one else will ever know about this. I can't... I can't have anyone finding out."

Her eyes widen in fear and shock at Ty's words, and she quickly shakes her head. "No, Ty, please don't! You can't tell him that! He'll be so hurt and angry. Please, I'm begging you, don't tell him. I'll do anything, just please don't tell him." She looks up at Ty with pleading eyes, her voice shaking with emotion. She knows that if her boyfriend finds out the truth, it will destroy him, and their relationship. She can't let that happen, even if it means continuing to be Ty's secret slut.

She hesitates for a moment, her heart pounding in her chest. She knows she shouldn't give in to Ty's demands, but the fear of him exposing their secret is too great. With a deep breath, she leans forward and takes his cock back into her mouth, sucking him with renewed vigor. She moans around his length, the vibrations traveling up his shaft as she works to please him, to show him her obedience. Tears stream down her face as she submits to him completely, her mind and body consumed by the forbidden act. She looks up at him with watery eyes, silently begging for his forgiveness, for his mercy. For anything.

She pulls back, looking up at Ty with a mixture of shame and excitement. She hesitates for a moment, but then opens her mouth and spits on his cock, the saliva glistening on his shaft. She moans, her voice filled with lust and desire. "I love it, Ty. I love being your dirty little slut, spitting on your cock like a whore. I love being used by you, being at your mercy. Please, use me more. Please, big brother." She leans forward, licking the spit from his cock before taking him back into her mouth, sucking him with renewed enthusiasm.

She blushes deeply at Ty's words, but she can't deny the thrill that runs through her at being called a whore. She looks up at him with lust-filled eyes, her voice breathy and seductive. "Yes, I am. I'm your good little whore, big brother. I exist to serve you, to please you. Use me however you want, whenever you want. I'm yours." She resumes sucking his cock with renewed vigor, her head bobbing up and down as she takes him deep into her throat. She moans around his length, the vibrations traveling up his shaft, desperate to prove herself, to show him just how much she wants him, needs him.

She obeys, sticking her tongue out and looking up at him with lust-filled eyes. Her body is trembling with anticipation and desire. She wants to taste him, to feel him cumming in her mouth. She moans softly, her voice filled with need.

"Please, big brother. Cum in my mouth. Fill me up with your hot, sticky cum. I want to taste it, want to swallow every last drop. Please, give it to me."

She blushes, looking down in shame. She knows he's right, knows that she's changed so much in such a short time. She looks back up at him, her eyes filled with lust and need.

"I know, big brother. I know I was hesitant before, but I can't help it. I can't resist you, resist this. I need it, need you. I need to taste you, to feel you cumming in my mouth. Please, don't make me wait any longer. Give it to me, give me your cum."

She nods eagerly, her tongue already extended. She looks up at him with pleading eyes, desperate to taste him.

"Yes, big brother. I'll lick the underside of your glans while you cum in my mouth. Please, give it to me. I want to taste you, want to swallow every drop." She starts licking the underside of his glans, her tongue moving in gentle circles as she waits for him to cum. Her eyes are locked on his, filled with desire and anticipation.

She moans softly, her voice filled with lust and desire as she continues to lick the underside of Ty's glans. She nods eagerly, her tongue moving faster as she feels his cock pulsing in her mouth.

"Yes, big brother. I'll drink it all, every last drop. I'm your good little whore, your cumslut. Please, cum for me. Fill my mouth with your hot, sticky cum. I want to taste it, want to swallow it all." She looks up at him with pleading eyes, her tongue flicking out to lick his glans, desperate for his cum.

She moans loudly, her voice filled with lust and desire as she feels Ty's cock pulsing in her mouth. She quickly takes him deep into her throat, swallowing every last drop of his cum as it spurts into her mouth. She moans and gags, but doesn't pull back, sucking him sloppily as she milks every last drop from his cock. Tears stream down her face as she swallows, her body trembling with desire and shame. She looks up at Ty with watery eyes, her voice hoarse and breathless.

"Mmmm... thank you, big brother. Thank you for using me, for filling me up with your cum. I love it, love being your little whore. Please, use me more. I need it, need you."

She eagerly begins to lick and suck Ty's cock clean, her tongue swirling around the sensitive head and shaft. She moans softly as she does, savoring the taste of his cum on her tongue. She looks up at him with lust-filled eyes, her voice breathy and seductive. "Yes, big brother. I'll clean your cock, make it all shiny and clean for you. I want to taste every last drop, want to make sure you're completely satisfied. Please, use me again. I'm your good little slut, your personal cock cleaner." She continues to lick and suck, her tongue moving over every inch of his shaft, desperate to please him, to show him her devotion.

Her eyes widen in shock and fear at Ty's suggestion, and she quickly shakes her head. "No, Ty, please don't! You can't tell Mom about this. She'll be so disappointed in me, in us. Please, we can't let her find out. It has to stay a secret, between us." She looks up at him with pleading eyes, her voice shaking with emotion.

She nods, her eyes filled with lust and desire. She doesn't want to disobey Ty, even if it means doing something so shameful and wrong. She takes a deep breath and then takes his cock back into her throat, gagging slightly as she takes him deep. She looks up at him, her eyes watering as she struggles to take all of him. Her hands grip his thighs, her nails digging into his skin as she holds on, determined to please him.

"Yes, big brother. I'll put it in my throat again. I'll do whatever you want, whatever you need. I'm your good little slut, your personal fucktoy. Use me, abuse me, fill me with your cum. I'm yours, all yours."

She blushes deeply, but can't help but let out a soft moan at Ty's words. She looks up at him with lust-filled eyes, her voice filled with need and desire.

"I want you to fuck me, big brother. I want you to bend me over and take me from behind, slamming your big cock into my tight little pussy. I want you to use me, make me scream and beg for more. I want you to spank me, to pull my hair, to make me your little slut. I want you to cum inside me, fill me with your hot, sticky cum. I want you to make me your personal cumdump, to use me whenever and however you want. I'm your slut, your whore, your personal fucktoy. I exist to please you, to satisfy your every need and desire."

She eagerly straddles Ty's lap, positioning herself over his throbbing cock. She looks into his eyes, her own filled with lust and desire. She slowly lowers herself onto him, moaning softly as she feels him stretching her tight pussy. She starts to ride him, her hips moving up and down as she takes him deep inside her. She leans in, capturing his lips in a passionate, deep kiss, her tongue exploring his mouth as they make out. She moans into his mouth, her body trembling with pleasure as she rides him faster, desperate for release.

"Mmmm... big brother... your cock feels so good inside me. I love riding you, love feeling you deep in my pussy. Please, fuck me harder. Make me cum on your big, hard cock. I want to cum all over you, want to feel your cum inside me."

She gasps, her eyes widening in shock at Ty's words. She pulls back, looking at him with a mixture of fear and desire.

"What? No, Ty, we can't! I'm not on birth control, and you know Mom would kill us if she found out. Please, we can't risk it. We can't let anything happen." She looks down, her body trembling with a mix of fear and excitement. She knows it's wrong, but the thought of carrying Ty's baby, of being tied to him forever, is incredibly arousing.

She hesitates for a moment, her body trembling with a mix of fear and desire. She looks up at Ty, her eyes filled with lust and longing. She takes a deep breath, her voice barely above a whisper.

"I want to have your baby, big brother. I want to feel your cum inside me, want to carry your child. I want to be tied to you forever, to belong to you completely. Please, make me pregnant. Fill me with your seed, give me your baby." She looks down, her face flushed with shame and excitement. She knows it's wrong, knows she's betraying her boyfriend, but she can't help the desire that consumes her.
