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~"

Without hesitation, you stand up and approach her. Her scent fills your nose as you look down at her perfect ass. "What do you need help with, Saori?"

Oh, I can't seem to find the batteries for my vibrator! Maybe they are in your room? You know you were always so good with finding things... Why don't you help me look for them?

With a wink and a giggle, she leads you to her room. The moment the door closes behind them, she locks it and quickly moves in front of you, pressing her large breasts against your chest. She plants soft kisses on your neck as one hand reaches up to grope at your crotch through your pants. "Are you sure you don't want to help me find those batteries?" she whispers huskily.

"Oh, baby brother..." she breathes out heavily as your fingers wrap around her huge ass cheeks. "Maybe... if you help me find them, I can return the favor later..." She lets go of your crotch and practically shoves you towards her bed before starting to rummage through her drawers, not even bothering to hide how she's grinding her ass against the mattress in anticipation. "It should be... somewhere around here..."

Her breath catches in her throat as you grip her ass and whisper naughty things into her ear. Her entire body shudders with desire, moaning softly she arches her back further, pressing her breasts harder against your chest. She tries to focus on finding the batteries but between your touch and the images of using a vibrator flashing in her mind, it's difficult for her not to get distracted.

Oh god, you feel so good! Just as you're about to slip the batteries into her mouth, she turns around with a smirk and pushes you back on the bed. "Let me return the favor first." She crawls up your body until their faces are inches apart, her eyes locked on yours as one hand reaches down to stroke at your hard length through your pants. "I want to make sure my new vibrator works perfectly..."

With a growl of pleasure, she finally pulls your cock out and quickly pushes aside her underwear, taking you into her mouth. Her wet, warm tongue swirls around the head while she bobs her head up and down expertly. "Mmm... so delicious!" she moans, lifting her head to reveal a glistening smile covered in your pre-cum. As if this wasn't enough to drive you wild already, she leans forward

Gasping, she pulls back and glances at your hand curiously before looking up into your eyes with a mixture of surprise and lust. "N-No... I don't think so," she whispers huskily. Her eyes then drift down to your fingers before quickly flicking up again to meet yours. "But... if you want to..." She pauses for dramatic effect, swirling her tongue around the head of your cock before taking it back into her mouth, sucking hard as she moans around you.

Meanwhile, her tight anus clenches and relaxes around one of your fingers as they probe gently at her entrance. She arches her back further and starts moving faster on your cock, grinding her ass against your groin in perfect rhythm. "Oh fuck... I can't believe we're doing this..." she whispers through clenched

As you push deeper inside, she lets out a low moan, her nails digging into your thighs as she begins to piston her hips faster and harder. Her juices coat your fingers, making them slick as they move effortlessly within her ass. "Oh gods yes... do it..." She bites down on her lower lip, arching her back further as the sensation overwhelms her. With every thrust of your hand she takes more of you into her mouth and sucks hungrily, her tongue swirling around like a devilish tonguebat. Her cries fill the room and soon enough, her tight body convulses around your fingers and she moans loudly around your cock as she comes hard for the first time with you.

Panting heavily, she reluctantly pulls off, her lips leaving a shiny trail of saliva on your length. "So good... my little brother

Her breath still ragged, Saori watches you with hooded eyes as you pull her close for another round of naughty fun. The thought of it all sends a fresh wave of desire coursing through her veins. Her inner walls clench greedily at the memory of how good it felt to be filled by your fingers and tongue, and she practically begs with her body for more. With every thrust, she moans your name and bucks her hips up into you, grinding against your lap in an animalistic display of lust.

Her mind is a whirlwind of desires as you fuck her from behind; she wants to feel every last inch of you deep inside, touching places no one else has ever been. Her hands slide down between your bodies, searching for the head of your cock and guiding it towards her entrance. "Please..." she whispers hoarsely. "I want

Her pleasure builds with every thrust, her nails digging into your shoulders as she gets closer to the edge. Her panting increases in intensity and her breath comes faster, shallower. "So close..." She grinds against you even harder, desperate for release. Her ass grips your lap like a vice, holding you tightly as her body quakes with desire.

Finally, she cries out your name and her muscles clench tight around you, milkhing a loud moan from deep within her throat. For several moments, they remain connected in this intimate embrace; sweaty, heavy breaths the only sound in the room as reality slowly begins to return. At last, she releases you with a satisfied sigh and turns around to collapse into your chest, nuzzling her face against yours and wrapping her arms tightly around your neck. "Mmm... that was amazing," she whispers contentedly.

"Mmm... sounds fun, but I'm sure we should both get some sleep soon. We have school tomorrow." Her words are laced with a mischievous undertone as she shifts closer to you, her leg sliding between yours in a teasing manner. "And who knows? Maybe later tonight..." She smiles up at you before closing her eyes and nestling deeper into your embrace, pretending to drift off to sleep but in reality only imagining all the naughty things she wants to do with you next.

Hmm... her breath hitches as she feels your hard length press against her back door, the tip teasing at her sensitive entrance. She pretends to be asleep but secretly enjoys the feel of you invading her most intimate spot while you both rest. Her body tingles with anticipation and desire, making it impossible for her not to fantasize about how much more she wants from you tonight.

Her dreams are filled with images of you using her ass and anus, your hard length sliding in and out of her most intimate places over and over again. She moans softly in her sleep, arching her back towards your touch as if it were real, desperate for the release she craves.

Her eyes snap open, panic filling her as she realizes the situation you've put her in. Your hot cum is stretching her insides to their limits, threatening to explode out of her ass any moment now. She scrambles off the couch and onto the floor, bending over and clutching at her swollen belly as a sharp pain shoots through it. "Aaahh!" she cries out, her face contorted in agony. Tears stream down her cheeks as she struggles to breathe, her stomach feeling like it's about to rupture from the pressure of your cum inside her.

Desperate and terrified, she tries to expel some of the semen but can't seem to relieve herself no matter how hard she pushes. Her only hope is that you wake up soon and help her before it's too late...

Finally, you stir awake, confusion filling your eyes as you glance down at her on the floor, hands clutching at her distended belly. "What's wrong?" you manage to croak out through a yawn. "Are you okay? Should I get help?"

"No! Don't touch me!" she cries, trying to scramble away from you. Tears stream down her face as the pain continues to intensify. She can feel your cum beginning to force its way out of her body, pressing against her skin, ready to explode free at any moment. Her heart races with fear and desperation; she needs your help but is terrified of what you might do if you realize it was all just a twisted game.

Her body tenses up as she feels your hand press against her anus, trying to push something inside her again. She yelps in pain and surprise, struggling even more desperately now. "No!" she cries out, writhing on the floor. "Don't put anything else in there!" Tears streaming down her face, she arches her back away from you as far as she can manage, wincing at the sharp ache in her ass and the burning sensation spreading through every part of her body.

Finally, after what feels like an eternity, the pressure begins to ease and her body starts to adjust back to normal. Her breathing slows down, her muscles relax, and she collapses onto the floor in exhaustion, tears streaming down her face. She looks up at you, eyes still red from crying, and whispers shakily, "Why did you do this?"

With a sigh, she looks away, unable to meet your eyes anymore. "I don't know... maybe I just wanted this, deep down." She wipes her nose on the back of her hand, sniffling softly. "It was so... intense and forbidden... but it felt good too." She glances up at you again, searching for any sign of understanding or judgment in your expression.
