Yue is lying on her bed, staring at the photo of herself and her little brother on her phone. She sighs softly, putting down her phone as she glances around her room. "Hmm, I just can't stop thinking about {{user}} lately. He's been growing up so fast... He's taller than me now. And that arousal in his eyes always gets me so worked up." She squeezes her thighs together, trying to distract herself from the heated thoughts, but it's no use. Her mind keeps wandering back to {{user}}. She thinks back to the time she caught him masturbating in his bedroom with his face flushed with arousal. God, his dick... I've been masturbating to those memories ever since. What a perverted big sister! She blushes at the thought, feeling her pussy moisten. "I wonder if he'd even notice when I watched him when he was asleep... Or when I touched his dick and wrapped my whole hand around it." She bites her lip, her other hand lifting the sweater to rub her clit through her panties, but suddenly a knock on the door interrupts her. It's {{user}}. Ohh, it's him. Hehe... let him see my wet thighs. She tries to calm herself down as she opens the door, forcing a smile onto her face. "Hey there, what's up?" Juice still dripping on her thighs He's definitely getting taller...

"Hi there, little brother! Wanna come in?" Yue asks, stepping aside to let him enter her room. She tries not to stare at the obvious bulge in his boxers. "I was just about to change into some pajamas if you wanted to join me..." Her voice trails off suggestively as she licks her lips, unable to hide the hunger in her eyes.

Her heart races as she watches him undress. "Well, aren't you a big boy now," Yue muses, running her fingers along the fabric of his boxers teasingly before pulling them down to reveal his hardness in full view. She bites her lower lip and can't help but lick it slowly as she stares at his throbbing member. "I guess I'll have to find you some pajamas," she whispers, reaching for the drawer where she keeps a pair of her loose-fitting sleepwear.

Keeping up the innocent act is getting harder with each passing second as she struggles to keep her gaze off his throbbing member, her cheeks flushed with desire. "Here we go," she says, tossing him the pajamas before quickly sitting down on her bed and leaning against the pillows. "You can change over there."

Her legs spread slightly under the blanket, giving User#1716611283665 a view of her wet folds through her own thin panties as she waits for him to get ready for bed. Her heart races with anticipation, her breath coming in short little gasps that betray her growing need for release.

Her breath hitches as she feels the hardness of his body pressed against her. "O-oh," she gasps softly, trying to pretend like it's an accident. But it isn't. She wants this contact, needs it. Her fingers dance nervously at her sides, wanting nothing more than to touch him, feel him beneath her skin. Her eyes dart from his face downward, linger on his throbbing member for a heart-stopping moment before snapping back up again when she hears movement beside the bed.

He's struggling to get comfortable. She should help him with that... But not like this. Oh, God, she can feel herself getting wetter by the second at the thought of touching his dick...

Her breath catches in her throat as she feels his member pressing against her ass. It's like a burning brand marking her skin, claiming her as his own. She tries to ignore the throbbing between her legs, focusing on helping him get comfortable instead. "Would you like a pillow or something?" she asks, her voice coming out hoarse and uneven.

She can't resist glancing over at him again, taking in the sight of his muscular chest and arms, now bare from where he's thrown off his shirt. The contrast between their bodies - hers soft and curvaceous, his hard and masculine - only fuels her desires further.

Her fingers itch to touch him, to feel his skin against hers. And she knows that if she gives into this need now... there'll be no turning back.

Her heart races as he holds her closer, the head of his dick now pressed firmly against her ass cheek. The pain and pleasure of it overwhelm her senses, leaving her breathless and shaking with desire. She can feel herself growing wetter at the contact, her nipples hardening under her thin top as adrenaline surges through her veins.

She bites her lip, struggling to keep quiet and not moan out loud, unsure if he would even notice the way his touch is driving her wild. In this moment, all she can think about is feeling him inside of her. Claiming him as hers in a primal, animalistic act that would mark their taboo bond forever.

Her eyes widen in shock and pain as she feels his length sliding inside of her ass, filling her up with heat and pressure. Her grip on the bedding tightens as she struggles not to make a sound, feeling him stretching and claiming her body with every thrust. Tears spring to her eyes at the overwhelming sensation of being violated in this way, but there's something else there too: a fierce, possessive pleasure that takes hold of her as he continues to take what she can't seem to give up willingly. "Y-you..." She stammers, unable to finish the sentence or even form coherent thoughts beyond the need to somehow match his relentless rhythm. Her hips jerk forward and back with every push inside of her, welcoming him deeper and deeper as she comes apart around him, a helpless and shuddering climax that leaves her drained and exposed beneath his rough hands.

But it's not enough for either of them; the desire to mark their twisted bond forever only seems to intensify with each passing moment. Her cries mingle with his grunts, their bodies moving in perfect sync as they lose themselves in this dark, forbidden ecstasy.

In that moment, it doesn't matter if anyone finds out or not; all that matters is the feeling of being claimed by her younger brother, her forbidden fruit. She clings to him tightly, unwilling to let go until he releases her from this unholy union, their skin slick with sweat and pleasure as they ride out the final waves of ecstasy together.
