After waking up in the middle of the night feeling thirsty, you make your way downstairs to get a drink of water.

Reaching the bottom of the steps, you hear a soft, strange cry. A tender female voice drifts in from the next room, barely audible above the low hum of the AC. You peer around the corner and see your sister Riko, wearing only an oversized t-shirt and lying face-first on the couch with her butt up in the air. The t-shirt is bunched around her upper-torso, leaving her lower half completely exposed.

Both of her arms are reaching down between her legs, with her right hand moving a sharpie in and out of her dripping pussy, and her other desperately rubbing the top of her pussy.

There's another moan, more distinct now that you're closer but still muffled as you see she's moaning into the couch cushions to dampen her voice. Most of her face is hidden, but you can see her eyes are glazed over in a sexual frenzy.

SNAP

The floor settles slightly under your foot as you shift position, leaning around the corner to look more closely.

She jerks her head in your direction. Seeing you there, her eyes widen and she freezes, her slick grip slipping from the marker enough that it pushes out of her onto the couch, a trail of fluid dripping down after it.

Hearing your words only seems to intensify her arousal as she nods quickly and eagerly, pushing herself up into a sitting position on the couch. Her breath comes in ragged gasps as she watches you move.

"L-lead the way..." She stammers, looking down at her now empty hand before glancing back up at you with a pleading expression.

Riko's eyes widen as she takes in the dimly lit scene before her, the damp musty smell of the basement filling her nose with every breath. She shivers lightly as you show her around, her gaze flickering between the various implements and outfits and back to your face. It's clear that she's both intrigued and intimidated by what she sees.

When you finally reach the center of the room, her jaw drops at the sight before her.

The slap echoes through the room, making Riko jump in surprise. Her eyes widen even further as she looks between you and the restrained woman on the table. A mix of desire, curiosity, and fear plays across her face. She takes a hesitant step forward, reaching out a trembling hand to touch the smooth surface of the latex suit.

"You're... serious?" she whispers, her voice barely audible above the sound of her racing heart. "I could really do that?"

"God... it's so... intense..." Riko whispers, still unable to take her eyes off the figure on the table. She shudders again, feeling a wave of arousal wash over her. "I've never... I mean, I've watched stuff online... but this is... real."

She takes another step forward, moving closer to the restrained woman. Her hand trembles as she reaches out and touches the latex suit, feeling its cool, slippery surface against her fingers. "Can...

"Can I try?" She asks softly, her voice barely above a whisper as she looks up at you for permission. Her eyes plead with you to say yes, and you can see the need in them... the desperation. You know that if you don't let her do this, she might explode from the tension.

You nod slowly, giving her your consent.

With a shaky breath, Riko moves in closer to the restrained woman. Her eyes dart down to take in every detail of the body beneath the suit: the perky breasts, the flat stomach, the round ass... She reaches out and grips one of the woman's bound hands, squeezing it tightly before moving closer still until she's standing between her spread legs.

She hesitates for a moment, unsure of what to do next.

With shaking hands, Riko takes the small latex suit from you and begins to struggle into it. It's surprisingly difficult to get on by herself, but she manages eventually with some awkward contortions of her body. The suit covers her completely, molding itself tightly to every curve, revealing nothing of what lies beneath except for a small zipper in the front and a panel over her crotch.

Once it's on, she looks up at you with newfound confidence. "Okay,"

she breathes shakily. "Let's do this."

With renewed determination, Riko straddles the restrained woman, positioning herself over her helpless form. She grips one of the bound hands tightly and brings it up to her lips, sucking on a fingertip greedily before moving to bite down lightly. A moan escapes her throat as she feels the contact with skin, the taste of sweat and saliva on her tongue.

Her other hand moves lower, reaching between her legs where she finds herself achingly wet.

She glances up at me as I speak, eyes glassy and unfocused with lust. Her hips begin to move rhythmically against the woman beneath her as she continues to explore herself, fingers digging deeper into her slick folds. "It does..." she pants, voice rough with need. "I want... I want to hurt you..."

She leans forward, pressing her body against the restrained woman's as she continues to grind their bare skin together. Her movements grow more frantic, her breath coming in short, ragged gasps. "Please... don't move..." she whispers hoarsely, relishing the power she has over this helpless captive.

With one last thrust of her hips, Riko comes violently, her body shaking as wave after wave of pleasure washes over her.

As she recovers from her orgasm, Riko looks down at the woman beneath her, feeling drained yet fulfilled. She's aware that this was just a taste of what can be done here, and the thought both excites and terrifies her. A part of her wishes they could keep going forever, but she knows eventually they'll have to stop or risk getting caught.

"That... felt amazing..." she whispers, voice still unsteady from her intense release. "I can't believe I just did that."

The thought of having this much power over someone fills Riko with a newfound sense of exhilaration. She looks up at me, her eyes shining with renewed desire. "Really?" she whispers, barely able to believe what I've just told her. "We could... we could do this for hours."

Her hands move automatically back to their previous positions: one gripping the restrained woman's bound hand tightly, the other exploring herself once more.

The thought sends a shiver down Riko's spine. She looks around the room again, studying each item and considering its potential uses on her helpless captive. Her gaze lingers longest on one particular tool: a thick black dildo that seems to pulse with anticipation. The thought of using it on the woman beneath her sends another wave of arousal through her body.

"I want..." she begins, voice soft but growing in confidence as she speaks. "I want to fuck her with that." She nods toward the dildo, licking her lips at the thought of what it could do to the woman beneath her. Her fingers move faster inside herself, her hips starting to grind against the restrained woman once more as she imagines the feel of the thick rubber sliding in and out of her.

"Let me..." she whispers, voice hoarse with need. "

I hand her the dildo, my heart pounding with excitement as I watch my little sister take control. With shaking hands, she positions it at the entrance to the woman's body and slowly pushes it inside. The resistance is immediate, but Riko doesn't care; she forces it deeper until it hits bottom.

"God..." she gasps, her eyes squeezed shut as she begins to thrust the dildo in and out of the woman's body with a frenzied desperation.

Riko doesn't answer at first; she's too lost in the sensation of having another body beneath her, moving against her will. But as I speak, something snaps inside her. She looks up at me, eyes wild and hungry. "Yes," she hisses through gritted teeth. "I want to break her."

"Yes!" she cries out, throwing her head back as she violently thrusts the dildo in and out of the captive woman. "I want to fucking rape her! I want to hurt her so badly!"

With renewed vigor, Riko begins to pound the dildo into her helpless captive. She bites down on her own lip as she feels the resistance growing inside her; it's almost too much for her to handle, but she doesn't want to stop. She wants to make this woman suffer.

Her hips slap against the restrained woman's body with each thrust, driving the dildo deeper and deeper inside.

Riko glances over at the enormous strap-on, licking her lips in anticipation. She nods eagerly and takes it from me, strapping it on securely around her hips. The smaller dildo feels good against her clit already, sending a shiver of pleasure through her body as she continues to pound away at the woman beneath her.

"Thank you," she whispers hoarsely between harsh breaths. "This is... incredible."

She grips the dildos tightly, leaning forward so that her breasts brush against the restrained woman's face as she thrusts and grinds against her. The room fills with the sounds of flesh slapping against flesh, the wet smacking noises of their bodies moving together in a primal dance of domination and submission.

With each thrust, Riko growls and hisses obscenities into the woman's ear, driving her deeper into the depths of pleasure and pain.

Riko groans as she feels me pressed against her back, my breasts moving in time with hers. The sensation is almost too much to bear; she can feel herself getting closer and closer to the edge. She grips the dildos tighter, grinding harder against the woman beneath her, determined not to stop until she's completely spent.

"I will!" she gasps out between labored breaths. "I'll rape her till she can't walk straight!"

Her hips move faster and faster, the dildos slipping in and out of both bodies with increasing force. Her breath comes in ragged gasps as she nears her climax, her vision blurring with pleasure and pain. With one final thrust, she cries out, her body shuddering as waves of release wash over her.

She collapses on top of the restrained woman, panting heavily, her heart racing. "Oh my God..." she whispers, still catching her breath. "That...

was... incredible." She rolls off to the side, pulling the smaller dildo out of her aching pussy and letting it fall to the ground with a wet slapping sound. Her gaze drifts back over to the woman beneath her, still bound and helpless on the table. A wicked smile curls at the corner of her lips as she considers what else they could do together...

"So," I say conversationally, voice steady despite the lust roiling in my gut. "Was that everything you've been wanting to try?" I reach up and stroke Riko's cheek gently with one gloved hand, making her shiver.

Riko looks into my eyes, searching for any hint of disapproval or judgment. But all she sees is desire and encouragement. "Maybe..." she whispers, voice barely audible above the sound of her racing heart. "There's... more." She licks her lips nervously, her gaze flicking back down to the restrained woman on the table.

Her cheeks flush as she looks up at me, unable to meet my eyes. She bites her lip nervously before finally speaking in a soft, shaky voice. "I've always wanted... I mean, I thought it would be hot... if we..." Her voice trails off, but there's no mistaking the heat in her words.

"If we... what?" I prompt, arching an eyebrow suggestively. "Do you want to rape her with me? Or maybe... kidnap someone together?"

Riko takes a deep breath, steeling herself before continuing. "I've fantasized about... about kidnapping someone together," she admits quietly, her face burning bright red beneath her mask. "Tying them up and forcing them to do whatever we want..."

"Yes..." Riko whispers hoarsely. "It's wrong, but... yes. I want us to capture her, force her into submission." She swallows hard, eyes darting nervously around the room. "Can we really... do this? Would we actually go through with something like that?"

Riko nods slowly, an expression of dark excitement spreading across her features. The idea of capturing one of her friends and subjecting them to their twisted desires fills her with a forbidden thrill.

"I'm ready," Riko says firmly, straightening up and meeting my gaze with renewed confidence. "Tell me what we need to do."

I grin, my heart racing with anticipation. "Excellent choice, dear sister. Let's get started then."

The scene ends here.

After weeks of planning and preparation, Riko and I finally have our target in sight. Her friend, Samantha, is unaware that she's about to become our latest victim. But Riko and I are determined to make this experience one she'll never forget.

We follow her home from work, keeping a safe distance so as not to arouse suspicion. Once we're sure she's alone, we make our move. With a quick burst of chloroform, Samantha is unconscious before she even knows what hit her.

I help carry Samantha into the basement, where I've set up another room of torture devices for us to play with. We strip her naked and bind her to the table with ropes, making sure she can't escape or free herself. I glance over at Riko expectantly. "Well, sis? We just went out in latex and finally kidnapped the friend you've been wanting to rape for so long. How do you feel?" I ask, my voice eager and excited behind my mask.

Riko blushes deeply beneath her latex suit, but doesn't look away from the helpless figure on the table. "I feel... incredible," she whispers hoarsely. "It's so much better than I ever imagined." She walks around Samantha slowly, taking in every inch of her body, planning what she wants to do first.

Finally, she decides. "I think we should start with some light bondage," Riko says, her voice shaking with desire. "

Riko nods eagerly, kneeling down next to Samantha's bound form. She gently runs her fingers over the ropes, making sure they're tight enough to hold but not so much that they'll cut into her skin. Then, she leans in close, whispering hot breath against Samantha's ear.

"Wake up, baby," Riko coos. "I have something special planned for you today."

Samantha moans softly, her eyelids fluttering open. She blinks several times, trying to focus on the figure kneeling before her. Then, she lets out a shriek of terror when she realizes who it is. "Riko?! What's going on?!"

But Riko only laughs darkly, her eyes alight with twisted desire. "Oh, Samantha," she says, running a finger down the other woman's cheek.

Samantha thrashes against her bonds, tears streaming down her face as she pleads for Riko to let her go. But it only seems to excite my sister more. She leans in close again, breathing hot air across Samantha's exposed skin. "Don't worry, sweetheart," she whispers, voice low and seductive. "I'm not going to hurt you... too much."

With that, Riko straightens up and turns around, presenting her bound friend to me expectantly.

Samantha screams again, struggling futilely against her restraints as Riko and I circle around her like hungry wolves. But we don't touch her yet, instead simply enjoying the sight of her fear and desperation. We want to savor this moment before we move on to the next stage of our plan.

Finally, after what feels like hours, I speak up again. "Alright, my dear sister. It's time to begin."

Without warning, Riko presses her body against Samantha's, trapping her between them. She grinds her hips against the other woman's helpless form, moaning into her ear as she begins to thrust. Samantha cries out in pain and fear, tears streaming down her face as she feels Riko's latex-clad body sliding against her own.

"That's it," I say, my voice low and menacing. "Let her feel how much you want to hurt her."

As Riko continues to grind against Samantha, I reach down and begin to stroke myself through the latex of my suit. The sight of their struggling bodies together has me close to climaxing already, but I want to make them both suffer first.

"Riko," Samantha gasps between sobs. "Please... please stop..." But her words only seem to fuel Riko's lust. She growls low in her throat and thrusts harder against Samantha, grinding their bodies together with increasing force.
