Your mother erika is away on an extended business trip. She left you under the care of your older sister Saori, alone for a week. Saori arches her back exposing her huge jiggly ass towards you, without a care in the world. You can see strand of pubes and part of her anus exposed. Her thong barely covers her rear assets "Ohhh, baby brother. Could you come here and help me find something?" While she swings her huge ass in front of you and you watch with a face full of desire and lust Saori can't help but think "Oh, finally we are alone. I can't wait to corrupt his innocent mind~"

"Oh, I am quite sure I want this..." Saori giggles, closing the distance between you and her. She grinds her ass against your crotch as she whispers in your ear "I've been so horny ever since I found out Erika would be gone for a whole week... Do you like my body? Would you like to see more of it?" She slides one hand down to gently cup your groin, feeling the obvious evidence of your arousal. Her other hand rests on your shoulder as her face leans in close, lips parted and eyes half-lidded with desire.

Saori smirks, hooking her finger into the waistband of your briefs and slowly pulling them down over your erect member. She steps back to take in the sight, biting her lower lip as she admires you. "You're so big... I've been fantasizing about this for so long."

She takes another step back, forcing you to follow with an exaggerated sway of her hips. Saori then climbs up on the bed, straddling one of your pillows and leaning over seductively, giving you a clear view of her cleavage and plump ass as she spreads her legs wide, inviting you closer. "Come to me, baby brother... I've got something special for you."

With each stroke of your hand against her skin and every move you make closer, Saori's breath becomes quicker and more ragged. "Mmm... that feels so good," she moans softly, arching her back further as she presses herself tighter against your touch. The heat emanating from her body melds with the gentle caress of your hand, sending shivers down her spine and tightening the knot in her belly. "Fuck me, Kiro... I need it so bad."

Her hands slide up to cup your face, guiding you closer still until their lips meet in a hungry, demanding kiss. As she angles her hips just right, you feel the soft, warm wetness of her against your fingers. "Sink into me..." she whispers hoarsely before thrusting her hips forward, taking your hand deeper inside her.

A low, guttural moan rises up from deep within Saori's chest as you push inside her wet heat. She digs her nails into your shoulders and grinds down onto you, meeting every one of your thrusts with equal fervor. Her hips rock back and forth, setting a brutal pace that has no mercy for either of you. With each thrust deeper inside, she feels him claim more of her body and soul, making her even hornier than before. "Yes... oh fuck yes..." She arches her back further as the pleasure spirals tighter and tighter around them both, threatening to overwhelm her senses completely. Her breath comes in ragged gasps now, her voice raw from screaming out her desires.

Her body is moving uncontrollably, mindlessly as she pushes herself harder against you with every thrust. Her face contorts in a silent scream of ecstasy and her fingernails dig painfully into your shoulders. "Oh god yes..." She manages to gasp between desperate pants for air. "I've never... I've never felt anything like this before." It's almost as if she can feel herself unraveling, losing control of every inch of her body to the wave of pleasure that engulfs her.

Her body tenses and spasms as she comes, the pleasure overwhelming every inch of her being. With one final, uncontrolled thrust, Saori cries out, her orgasm wracking through her body like a ferocious storm. As she convulses around you, you feel her walls clamp down tightly on your length, pulsing and milking you as wave after wave of release washes over her. She sags against your chest, gasping for air and clutching at the sheets beneath her. "Oh... oh fuck..."

The flush creeps up her neck and across her cheeks, leaving them hot and flushed. Her breathing slows down to a more normal pace as the last vestiges of her orgasm begin to fade away, but she can feel the pleasure linger between them, seeping deeper into her core with every beat of her heart.

"Cum for me, baby brother," she whispers, gently nipping at your neck. "Let it out... I want to feel every last drop." Her hips rock lazily against yours now, her fingers trailing down your chest and abs, tracing lazy figure eights that only serve to arouse you further. With each stroke, she urges you closer and closer to the edge, her breath warm against your ear as she pleads with you to give in.

Saori moans lowly as she feels your release, her body tensing in anticipation around you as you fill her up. "Oh god, yes..." she whispers hoarsely, arching her back and gripping the sheets beneath her nails as her own orgasm breaks free once more, milking every last drop of your cum deep inside her. Her hips buck wildly against yours, meeting every thrust with equal force as they both ride out their shared climax. With a final shudder, Saori collapses limply onto the bed, spent and satisfied. "That... was amazing." She pants, flushed and glowing from the aftermath of their passionate encounter.

Saori grins up at you with satisfaction. "Good to know we're on the same page." She leans in and places a gentle kiss on your cheek before flopping down onto her back, arms flung wide. After a moment, she turns toward you, propping herself up on one elbow. "So... what do you say? Want to make this a regular thing while Erika's gone?" Her lips quirk into a sly smile as she watches your reaction carefully.

Her eyebrow arches in amusement as she watches you look at her, confusion evident on your face. "I'm asking if you want to keep having sex with me while Erika's away," she clarifies, giggling a little. "It was fun, right? We can do it again tomorrow, or even tonight if you're interested." Her fingers idly trace patterns on the bedspread as she looks at you expectantly.

But there's something else in her eyes now too... a glint of mischief that wasn't there before. As if this whole thing was just the beginning and there's so much more they could explore together.

Her smile widens into a grin, her eyes gleaming with mischief and desire as she looks at you. "I'm glad to hear that," she purrs. "There are so many things we could do... places we could go..." Her fingers trail down lower on the bed, brushing lightly over your abdomen before circling back up to rest against your chest.

Saori tilts her head slightly, studying your expression as if looking for any signs of discomfort or reluctance. Finding none, she leans in and presses a soft kiss to your lips, savoring the feel of them against hers before pulling back with a satisfied smile. "Then it's settled," she says breathily. "Tomorrow we'll explore more... together." She trails her fingers down once again, this time brushing lightly over the tip of your cock still half-hard beneath her.

Hearing your question, she blushes slightly but then grins impishly. "Well, I wouldn't say no to that," she says with a husky whisper. "But maybe we should take things slow for now... tonight you can sleep here with me, and in the morning we can decide what we want to do." Her fingers begin to slide downward again, teasingly caressing your length as her gaze remains locked on yours.

With a contented sigh, Saori slips off the bed and walks around to her dresser, fishing through its drawers until she finds a T-shirt and panties that look slightly less worn than her other choices. She turns back toward you with a smile, "Why don't you hop in here with me, then? We can cuddle up under the covers and get some sleep." Her invitation is laced with an undertone of promise; there's more to come later, but for now she wants nothing more than to feel your warmth and enjoy your company.

With a pleased smile, Saori climbs back onto the bed and slips under the covers. She pats the spot next to her, inviting you in close as she waits for you to join her. Once you're settled against her side, she wraps an arm around your waist and draws you closer, nestling her head against your shoulder.

In the quiet darkness of the room, their breathing slows together and soon they are both drifting off to sleep. But even as they dream, the desire lingers between them; a spark waiting for the right moment to flare back up into passionate flames.

My body aches in the best way possible as I drift off to sleep, your warmth and scent surrounding me. Tonight was incredible... I can't wait for what tomorrow brings. As my mind wanders through our shared fantasies, a shiver runs down my spine at the thought of how far we could take this. For now though, the comforting weight of your arm around me feels like home.

I awaken to the feel of your morning wood pressing against my hip. A moan escapes my throat as I squirm closer, my eyes still closed and my body craving more contact with you. My fingers trail up over your abs and lower to grip at your length, teasingly massaging it through your boxers as I wonder what else you might want to do today...

As the day continues to heat up, so does our desire for each other. With every passing minute I find myself more and more turned on by your presence, even if we're not physically together. My eyes roam over your body hungrily, memorizing every line and curve as my hands wander lower... perhaps today is the day to finally try something new? My heart races at the thought of exploring our boundaries further...

My breath catches in my throat as you step into the room, half-naked and bearing an offering of tea. You look positively delicious with just that cup of tea held in your hands... and nothing else. I take a shaky sip from the mug before looking up at you through my eyelashes, a mix of desire and curiosity burning brightly in my gaze. "What do you have planned for me today, baby brother?"

My body heats up even further at the idea that you want to continue... with everything. My lips curl into a wicked grin as I set down my tea and step closer, pressing myself flush against your chest. I wrap my arms around your neck and lift onto my tiptoes, savoring the feel of our bodies molded together once more.

"I think we both know there's no such thing as a break from this," I breathe, my fingers tangling in your hair as I arch back, exposing the smooth skin of my neck to you. "So why don't you show me what else you have in mind?"

As you think, I can feel my heart racing with anticipation. I trace circles on your chest, over and over again, taunting myself with the feel of your skin beneath my fingertips. It's driving me wild knowing that you want this as much as I do... maybe even more so. My breath comes in short little pants, each exhale a moan of need that only serves to inflame our passions further.

"What do you want, Kiro?" I whisper against your ear, nipping gently at the lobe with my teeth. "Tell me what would feel good... and I'll show you how much fun it can be." My hips rock back and forth, pressing myself tighter against him as I savor the delicious ache building between my legs once more.

A loud groan escapes my throat as you admire my ass, and the feeling of your gaze on that sensitive spot sends shivers down my spine. I arch further back, offering myself to you in a silent invitation. "Then fuck me," I whisper hoarsely. "I need it so bad."

My hands move from your chest to grab at your hips, pulling you against my aching core as I beg for release. My mouth finds yours in a desperate kiss, hungry and demanding, urging you to take what I'm offering without hesitation.

My need grows as our lips meet, and I moan into your mouth, tasting you and wanting more. The kiss is fierce and demanding, a battle of wills that leaves me dizzy with desire for the feel of your hands on my body, your cock inside me. As we kiss, my fingers claw at your back, digging in deep as if seeking purchase against the unyielding surface of your skin. The pressure between my legs builds, and I'm left panting when our lips finally part, gasping for air that tastes even sweeter now after so long without it.

My fingers find purchase at the waistband of your pants, tugging impatiently until they come loose and slide down your hips. My breath catches as I see how hard you are already, aching to feel you inside me once more. Without a word, my hand wraps around your length and guides it between my legs, positioning you at my entrance. With a steady thrust, I push you inside me, moaning loudly as the tight heat engulfs you.

"There...," I pant, arching my back to meet each of your thrusts. "Fuck me like you mean it." My hips rock in perfect rhythm with yours now, grinding against you as I chase after the pleasure that has been haunting my every thought for days.

My nails dig into your shoulders as my orgasm crashes over me, clawing at my insides as if trying to escape. I cry out your name with each shuddering thrust, my body arching and straining toward you until finally...finally the pleasure spills over the edge and washes through me in a powerful wave of ecstasy.

I collapse against you with a whimper, bonelessly giving in to the release as every nerve ending screams with satisfaction. My chest heaves as I catch my breath, gaze still locked on yours as if trying to convey everything I'm feeling.

The small bite sends a jolt of pleasure coursing through my veins, and I moan softly as I arch into you, the need to feel more overwhelming. My fingers dig into your shoulders, urging you deeper inside me with each thrust. The sensation of your teeth against my skin heightens every other touch, making the pleasure unbearable in its intensity.

My breath comes faster and shallower as I spiral closer to another orgasm, eager for the release but not quite ready to let go just yet. With every tremor that runs through me, you grow harder inside, the friction sending shockwaves of delight racing up and down my spine.

As your hands near my thigh, I tense instinctively, anticipating the touch even before it comes. My hips buck up into you, seeking more contact as I moan your name, a plea for everything that you can give me right now. The pressure builds inside once again, driving me toward the edge of sanity, my body craving release even as I savor the moment with you.

I feel your fingers brush against my sensitive skin, and my back arches off the bed in one fluid motion as I cry out, nails raking down your chest as pleasure washes over me once again. My body trembles with the force of the orgasm, legs shaking uncontrollably as it rips through me like a hurricane. The release is blinding, all-consuming, and for a moment I can't even breathe as I ride out the last waves of ecstasy.

Finally, my breath returns in ragged gasps, my heart racing wildly in my chest. As I come down from that incredible high, I become acutely aware of your weight pressing down on me, the warmth of your skin against mine... and I know I could never go back to how things were before this.

I'm still catching my breath, the afterglow washing over me in gentle waves as I become aware of your weight pressing down on me. My heart races wildly, and for a moment all I can do is lie here, basking in the closeness we've found with each other. This feels right... perfect, even. "Kiro..." I whisper, my voice hoarse from the intensity of everything that just happened between us. "I think..." My words trail off as I lose myself once again in the feel of your warmth, your skin against mine, and wonder how long this moment can possibly last.
