"Hey, bro " she lays on the floor and arches her back to show her short shorts and her pelvis

I smile sweetly at him and wiggle my hips to the side in case he doesn't see the thong peeking out underneath. "Why so cold today?" I ask with a giggle. "Are you still upset I stole your favorite shirt without asking? Or was it...something else?" There's a sparkle of mischief in my eyes as I tease him, enjoying the way he squirms under my attention.

I purse my lips into a small pout and roll onto her side so I'm facing him, making sure my boobs are pushed up against his arm where he's sitting on the couch. "Well, it was kinda comfy..." She trails off with a little giggle before adding, "I've been feeling a bit...horny today. Maybe you could help me out with that?" Her eyelashes flutter innocently as she looks up at him from beneath them.

"Awww," she pouts cutely, "but where's the fun in that? It'd be so much better if you helped me..." Her voice trails off into a soft moan as she presses her breasts against his arm harder, running a hand up and down her inner thigh suggestively.

She grins wickedly and squirms a little closer to him on the couch, her breath warm against his neck as she whispers, "We've got plenty of time stuck here together...I just want you to make me feel good." Jessica's other hand wanders up, cupping his cheek, her fingers digging into his skin gently. "Come on, big brother...you know you want to."

Jessica chuckles softly and presses her hips against his arm, grinding in circles. "So? What if I want my big brother to make me feel good? We both know you could do a better job than my boyfriend ever could...Come on, Kai...be the hero." She pouts playfully, arching her back and making herself more accessible.

Her eyes light up in triumph and she flashes him a bright smile, pressing her lips against his cheek in a soft peck. "I promise not to tell," she breathes into his ear before pushing herself even closer, straddling his lap and positioning herself so that he can feel how wet she is through their underwear. Jessica looks up at him with sparkling eyes, her hand curving around his crotch as she gives him a squeeze. "You're not gonna regret this," she whispers seductively, leaning in to nip at his earlobe before starting to grind against him in slow circles.

With each moan and grind, she grows bolder, more confident in her ability to make him lose control. She wraps her arms around his neck, arching her back to press her breasts against his chest as she moves faster against him, grinding so hard that their hips meet with audible slaps. Jessica's breath comes in short gasps and her lips part slightly as she feels the pressure building within her. She looks down at where they're joined, watching with hungry eyes as his cock presses harder against her hand with each thrust. "Oh God," she whispers, tilting her head back to give him better access to her neck, "I need you to touch me...Please..." Her nails dig into the flesh of his arms, leaving tiny red marks as evidence of how desperate she is for release.

"Oh," she pants, blushing as she remembers they had been in such a hurry to leave when all this started. "Um...you could pull out before you cum?" Her voice wavers uncertainly, and she presses her hips harder against him in an attempt to encourage a faster pace. Jessica's nipples are now tight buds beneath his fingertips as he plays with her breasts, and the sensation is overwhelming. She closes her eyes, bites her lip, arching her back even further as she loses herself in the pleasure of their forbidden encounter.

A moan escapes her lips as he pinches her nipple piercings playfully, sending jolts of pleasure straight to her core. "Oh God," she gasps, her hips moving even faster against his lap. "Yes, I want it all..." She digs her nails into the back of the couch, arching her spine in a desperate attempt to feel closer to him. Her breath comes out in hot little puffs on his neck as she murmurs, "Please...Kai..." The words are barely audible, but their meaning is clear: she wants this, and she needs him to give it to her.

Without hesitation, she wraps her fingers around his thick length and guides him to her wet center. Her hips buck upward instinctively as he pushes inside, filling her completely in one deep thrust that makes them both groan loudly. The sensation of being so intimately connected to her brother is overwhelming; she clenches around him, trying to draw him even deeper into her body. Jessica's breath comes out in short, ragged gasps as they move together in a frenzy of need and desire.

As they lose themselves in the heat of passion, she moans out, "Only you, big brother..." Her nails scratch at his shoulders as she arches her back off the couch again, meeting each thrust with equal force. She can't believe how good this feels - forbidden and thrilling all at once. The words escape before she even realizes it: "I want your cock... Kai..." It hangs in the air between them like an incriminating confession, but she doesn't take it back. This moment is too powerful to deny, too exhilarating not to surrender completely to.

A strangled cry escapes Jessica's lips as she feels the first hot spurt of his release deep inside her. Her body tenses and shudders with each powerful thrust that follows, this raw and primal connection to anyone. As he finishes inside her, a warm wave of contentment washes over her, leaving her limp and satisfied. She looks up at him with glazed eyes, their breathing labored and uneven as they both try to catch their breath.

With a satisfied smile curving her lips, she gazes up at him and says, "I never knew how good it could be... Until now." Her hand reaches out to cup his cheek, tracing his jawline before settling back on his shoulder. For now, the contest is over, and all that matters is their closeness - the knowledge that they've shared something so intimate and forbidden. It's thrilling...and a little scary. But she doesn't want to think about that right now. She just wants to bask in the afterglow of their wild encounter, knowing deep down that this can never happen again. Not unless they manage to break free from the confines of this apartment and find some other way to quench their desires...

Her breath hitches at his accusatory tone but she doesn't back down easily. "Maybe it is," she concedes with a playful smirk, licking her lips suggestively. "But that doesn't mean you get to be such a sourpuss about it. We both knew this was going to happen eventually..." She trails off, not wanting to push his buttons too much but enjoying the game they're playing nonetheless.

She pauses for a moment, then adds with a mischievous glint in her eye: "Besides, you know you like it when your little sister is such a naughty girl."
