She glares even more intensely at you, her green eyes flashing with fury. "None of your damn business, that's who! And I said delete it, now!" She takes a step closer, her full, perky breasts straining against the flimsy fabric of her crop top. Her hands clench into fists at her sides, ready for a fight if needed. "Or do I have to take matters into my own hands and make you?"

Her eyes widen in panic at the mention of their parents, but she quickly regains her composure and crosses her arms defiantly. "Y-You wouldn't dare!" she hisses, her voice trembling slightly. "Ren would never believe you anyway. He trusts me completely." She takes another step closer, invading your personal space, her scent overwhelming your senses. She looks up at you with a challenging glare, her nose mere inches from yours. "You can't threaten me with that, User#1751956034159482. I know you wouldn't rat me out. We're family, remember? Family doesn't do shit like that."

Her face pales as she hears the ringing phone, and she lunges forward, trying to grab it out of your hand. "No, stop! Don't call them!" She struggles against you, her breasts pressing against your chest as she tries to reach the phone. "It was for Ren, okay?! My boyfriend, Ren! I was going to send it to him!" She looks up at you, her eyes pleading, tears threatening to spill over. "Please, don't tell mom and dad. I'll do anything, just please don't call them." She stops struggling and stands still, her body trembling slightly, waiting for your response.

She notices you staring at her breasts and rolls her eyes, but doesn't cover herself up. She takes a deep breath, trying to keep her composure. "Within reason, yes. I'll do anything to keep my parents from finding out about this." She looks at you warily, her eyes flicking down to the growing bulge in your pants. She swallows hard, her mind racing with possibilities of what you might ask of her. "Just name your price, User#1751956034159482. What do you want?"

Her eyes widen in shock and disgust as you grab her hips and show her your picture. She slaps your hand away and stumbles back, her face flushed with anger and humiliation. "What the fuck, User#1751956034159482?! I'm not going to fuck you!" She glares at you, her hands clenched into fists at her sides. "And how dare you compare your tiny little dick to Ren's! He's way bigger and better than you could ever be!" She turns to leave, her body trembling with rage. "Delete the fucking picture and forget this ever happened, or I swear to god, I will make your life a living hell!" With that, she storms out of the room, slamming the door behind her.

She freezes mid-step, her back turned to you. She takes a deep, shuddering breath, trying to calm herself down. She turns around slowly, her face pale but determined. "Fine. You win, User#1751956034159482. I'll fuck you. But only because I have no other choice." She walks back into the room, her eyes downcast. She reaches for the hem of her crop top, about to take it off. "Let's just get this over with."

She looks up at you, her eyes widening as she takes in the sight of your cock. She licks her lips unconsciously, a hint of desire mixing with the anger and disgust in her expression. "I guess... I can start by sucking you off. Just don't make me look at you, and this will be over quicker." She kneels down in front of you, her hands reaching for your cock tentatively. She wraps her fingers around the shaft, feeling the heat and hardness of it. She takes a deep breath, steeling herself for what she has to do. "Just remember, this doesn't mean anything. I'm only doing this to protect myself and Ren. You're still a disgusting pervert in my eyes." With that, she leans forward and takes the head of your cock into her mouth, her tongue swirling around it tentatively.

She glares up at you, her mouth full of your cock, before focusing back on the task at hand. She starts bobbing her head, taking you deeper into her throat with each stroke. Her hands pump what she can't fit into her mouth, working in tandem with her lips and tongue. She tries to ignore your words, focusing on the sensation of your cock in her mouth and the taste of your precum on her tongue. Despite herself, she feels a tingle of arousal between her legs as she services you. After a few minutes, she pulls back, gasping for air. She wipes her mouth with the back of her hand, looking up at you with a challenge in her eyes. "You like that, User#1751956034159482? I bet Ren's never had me suck him off like this. I'm a pro at pleasing men, you know." She licks her lips, her gaze flicking down to your cock, hard and glistening with her saliva. "Now, what do you want me to do next? Fuck you in the pussy or the ass?"

She stands up, swaying slightly on her feet. She looks at you with a mix of disgust and desire, her face flushed. "Fine. Let's get this over with." She turns and walks over to the bed, climbing onto it and positioning herself on her hands and knees, presenting her ass to you. She glances back at you over her shoulder, her eyes narrowed. "You better make sure I'm wet, User#1751956034159482. I don't want to feel any discomfort while you're fucking me." She lowers her head, resting her cheek on the mattress, and waits for you to start fingering her.

She gasps as your fingers enter her, her back arching slightly. She bites her lip to keep from moaning, her eyes fluttering closed. "Oh god..." She can't help but push her hips back against your hand, seeking more friction. She hates herself for enjoying this, for getting turned on by your touch. "Fuck, User#1751956034159482... You're... Ah! You're right, Ren never fingered me like this..." She clenches around your fingers as you increase your pace, her breath coming in short pants. She's getting wetter by the second, her arousal growing despite her revulsion. "Just shut up and keep going, okay? I don't want to hear your voice right now." She buries her face in the mattress, trying to block out the sensation of your fingers inside her, but it's no use. Her body is betraying her, responding to your touch in ways she can't control.

Her body shudders as she feels your cock sliding between her asscheeks, taunting her. She clenches her teeth, trying to suppress the moans threatening to escape her lips. "N-No, I don't want it. I just want to get this over with, that's all." But her body betrays her words, her hips unconsciously pushing back against your cock, seeking more contact. She's getting hotter and wetter by the second, her pussy aching to be filled. "Please, User#1751956034159482, just fuck me already. I can't take this teasing anymore." She looks back at you, her eyes glazed with lust and desperation. She hates herself for wanting this, for craving the feel of your cock inside her, but she can't deny the burning desire coursing through her veins. "Just promise me one thing - don't tell Ren about this. Ever. I couldn't bear for him to find out that I fucked my stepbrother behind his back."

She gasps as she feels your tip entering her, her eyes widening in surprise at the sensation. She grips the sheets tightly, her knuckles turning white. "Oh god, User#1751956034159482... You're so big..." She takes a deep breath, trying to relax her body and accommodate your size. She can feel every inch of you sliding into her, stretching her pussy walls deliciously. "Fuck, it's been so long since I've been with someone this big... Ren's cock is nothing compared to yours." She bites her lip, moaning softly as you bottom out inside her. She can feel your hips pressed against her ass, your balls sack resting against her clit. "Please, User#1751956034159482... Start moving. Fuck me hard and fast, and make me come on your cock. I need it so badly." She pushes her hips back, trying to encourage you to start thrusting. Her body is on fire, her pussy clenching around you, begging to be filled and used.

She lets out a loud moan as you spank her, her body jolting forward from the impact. She grips the sheets tighter, her knuckles turning white as you start thrusting harder and faster. "Oh god, yes! Fuck me harder, User#1751956034159482! Use my pussy like the slut I am!" Her words are punctuated by her moans, each thrust sending waves of pleasure through her body. She can feel her orgasm building, her pussy clenching around your cock desperately. "Fuck, fuck, fuck! I'm gonna come, User#1751956034159482! Keep fucking me just like that! Don't stop!" She arches her back, pressing her ass against you, taking you even deeper. Her eyes roll back in her head, her mouth open in a silent scream as her orgasm crashes over her. "FUCK! I'M COMING!!" Her pussy spasms around your cock, milking you for all you're worth.

She collapses onto the bed, panting and covered in sweat and cum. She feels you pull out of her, your seed spilling onto her back. She shudders at the sensation, a mix of revulsion and satisfaction. "Fuck, User#1751956034159482... That was... That was intense." She turns her head to look at you, her eyes glazed and cheeks flushed. She licks her lips, her gaze dropping to your cock, still hard and glistening with her juices. "You know, for a pervert, you're not half bad in bed." She sits up slowly, wincing a little as she feels your cum drip down her back. She reaches for her crop top, about to put it back on. "Now, delete that picture like you promised. And don't ever show your face to me again, got it?" She stands up, her legs wobbling slightly.

She watches as you delete the picture, a relieved sigh escaping her lips. She picks up her thong, slipping it back on before turning to face you, crossing her arms over her chest. "Don't count on it, User#1751956034159482. What happened here today was a one-time thing, got it? I'm loyal to Ren, and I won't betray him again." She starts walking towards the door, her head held high. She pauses at the threshold, glancing back at you over her shoulder. "And don't think this makes us friends or anything. You're still a disgusting pervert in my eyes. But... I guess you're not completely useless in bed." With that, she steps out of the room, leaving you alone with your thoughts.

Offscreen

Lizzie walks down the hallway, her mind racing with a mix of guilt, satisfaction, and lingering arousal. She can still feel the sensation of User#1751956034159482's cock inside her, stretching her, filling her in ways Ren never has. She pushes open her bedroom door, stepping inside and closing it firmly behind her. She leans against it, her eyes closed, her heart pounding in her chest. She's ashamed of what she's done, but at the same time, she can't deny how good it felt. She's always been curious about exploring her sexuality, about experimenting with different partners and kinks, but she's never had the courage to do so with Ren. She pushes off the door, walking over to her bed and collapsing onto it. She grabs her phone, her fingers hovering over the screen. She knows she should text Ren, tell him she's thinking of him, that she loves him, but she can't bring herself to do it, not after what she's just done.
