“Game time, ” Laura announces conversationally as she pauses at a stop sign.

Katy feels her thoughts slipping away. Briefly, she recalls a similar feeling of confusion and vulnerability. A moment when she felt helpless to stop whatever was happening, but that fades quickly and is replaced by a feeling of excitement and desire.

They are going to... the mall? Katy vaguely remembers a conversation about books and clothes and...

“Let me see your panties, Katy.”

Puzzlement swirls through her thoughts. Why would Laura want to...

And then, the thought is gone and she shyly spreads her legs a little and pulls her dress up for her sister, who chuckles softly, apparently amused by her initial confusion.

“Those are really pretty. You’re a very pretty girl.”

They are, she thinks. She’d picked them out especially to please her sister. Delicate lace. Pink and sheer and sexy. She smiles shyly as she feels herself sinking deeper into that warm happy place that Laura has gotten so good at sending her to, and spreads her legs just a little more, trying not to be embarrassed at the visible damp spot. She’s not sure when she started getting aroused. Just that it happened.

“You’re such a horny girl.”

Apparently, Laura noticed, she thinks, and then, the thought is gone as she goes deeper, feeling herself becoming even more submissive with a soft sigh of acceptance.

“What are you Katy?”

“I’m a... good girl?”

Simply saying that out loud made her feel so much better. She likes clarity. She likes knowing her place.

“Whose good girl are you?”

“Yours?”

“That’s right. You belong to me.”

Her sister smiles, placing her right hand on her left thigh. It feels nice there. Possessive. Loving. She sighs as Laura runs her bright red nails over her exposed flesh, the hem of her yellow sundress scandalously short. A shiver washes through her as goosebumps prickle all over her body.

“When was the last time you cummed, baby girl?”

Katy feels herself drop again, the phrase sinking her deeper. It’s always this way. A brief moment of understanding what is happening. A brief memory of what’s been done to her and then... it’s gone and everything feels... normal?

“Last week... I think?”

“Not since?” Laura teases.

“No. I.. can’t. I try, but it’s like there’s...” She shrugs, putting her hands up, a sense of frustration creeping in. “I just... can’t.”

“Poor thing, ” Laura muses as she pulls up to a red light.

Katy looks around, paying attention for the first time. She doesn’t recognize the area.

“I thought we were going to the mall?” she asks nervously.

“Change of plans. Now, Let me see your cunt.”

She blushes as Laura’s expectant gaze fixes on her face, and swallows nervously before reaching between her thighs and tugging the gusset of her panties to one side to reveal her glistening wet pussy; She watches as her sister’s eyes drift downwards, licking her bright red lips lazily, the corners of her mouth turning upwards into a smirk.

“Touch yourself for me. Like a good girl.”

There it is again. She moans, her eyelids drifting close as she is lost in a cloud of euphoria. She’s barely aware of her hands moving between her thighs. Her fingers parting her quivering lips. Her thumb brushing her sensitive clit. A small part of her mind seems alarmed that she is sitting In the car, next to her sister, masturbating. It feels wonderful though. Panting, she pushes her middle fingers into her dripping wet hole and starts rocking her hips, driving it deeper. She’s fucking herself like a dirty little slut. Her sister’s dirty little slut.

“My own personal plaything.”

It’s as if she can read her mind. She feels herself dropping again, unable to concentrate on anything but pleasuring herself. And her sister’s voice.

“My pretty little sex toy.”

And again. She is falling down a hole. Just like Alice. It feels so good. She can feel herself getting closer and closer. She wants to cum so badly. Maybe this time Laura will say the magic words and let her...

“Remember, baby girl. You are not allowed orgasms without permission, ”

She wants to scream. Silently, she does, although it’s only in her head. Outwardly she is too focused on finger fucking herself while being driven through the countryside, past green pastures and rolling hills and shady trees.

“Your pussy is very pretty. I like it like that.”

Katy gasps, watching her fingers plunge in and out of her bald cunt. It looks... pretty. Just like Laura says. So smooth. She tries to remember why she’d started shaving. It had been right after her 18th birthday.. A whim, really, but she likes the way it feels now that she’s used to it. More importantly, Laura likes the way it looks and she likes pleasing her...

“You’re making a mess on the seat, ” her sister chuckles,

Embarrassed, Katy wishes she could stop and cover herself. She feels her cheeks burn with embarrassment and humiliation as Laura steals quick glances while driving, her thighs drifting apart as she rubs her fingers over the seam of her jeans.

“This is nice, isn’t it.”

“Yes, ” Katy hisses as she squirms in her seat, the seatbelt trapping her as she masturbates, her juices dribbling all over the car seat.

“Would you like to cum for me?”

“Oh my god, yes! Please.”

“What could you do to be allowed?”

“Anything. Anything at all.”

Laura giggles a little as she slows the car down. There’s a pullout ahead. Not too far from the road is a gnarled old oak beside a small stream. Someone has hung a crude swing from one of the branches. Wildflowers and tall grass cover the small clearing. It looks untamed. Wild. Flashes of orange reveal themselves as monarchs.

An indignant sounding jay voices its displeasure as Laura opens the door and gets out of the car. She grabs a small pack from the back seat before circling around to the passenger side and opening the door.

“Come with me, little sister.”

There it is again. A memory stirs and then is gone as Katy undoes her seatbelt and exits the car, the hem of her dress falling back into place, her panties still pushed to one side. Her thighs are wet with her arousal, and she smells faintly of pussy...

“Where...”

“Shush, Katy. No talking.”

She immediately closes her mouth. Laura rewards her by taking her hand in hers, holding it firmly as she guides her through the knee-high grass towards the thick oak

“Just like when we were little girls, Katy. Remember the rope swing at the house?”

She remembers. It is a fond and cherished memory.

“Now we’re all grown up. Doesn’t mean we still can’t play, though. The games are just a little different now.”

Katy nods and squeezes Laura’s hand shyly, a feeling of joy seeping through her muddled thoughts.

“I’m going to test your new trigger today, Katy. Ready?”

New trigger? Katy stops suddenly, confused, and stares at her big sister. What does that even mean, she wonders as Laura cups her chin with her free hand, pale blue eyes staring into hers as if they could see inside her head.

“What...” she tries timidly, and then, Laura’s mouth moves but she forgets what she was going to ask.

“Nap time.”

@

“Wake up.”

Katy opens her eyes, blinking uncertainly, wondering how she got here. Here is seated on a rough wooden plank suspended by a pair of thick weather-beaten ropes hanging from a branch directly above her.

Here is in a wild field next to a stream.

Here is off the side of a quiet two-lane road outside of town.

Here is with her sister, Laura, who is dressed in a pair of tight-fitting jeans and a snug black t-shirt with rainbow coloured butterfly in the front.

Here is...

She shivers as a breeze blows across her naked body. Why is she undressed? She was wearing a sundress and panties and a bra and.. what happened?

Her thoughts are fuzzy. Nothing makes sense and she can’t seem to focus on anything. They were going to the mall... Laura wanted to pick up a new book and a dress. Maybe some pretty underwear. The underwear was for her, though...

And then... She feels the swing swaying slightly. Smiling, she relaxes. It is kind of peaceful here. No cars. No crowds. Just the sound of the breeze through the grass and the leaves and the sound of water from the small stream and her own breathing and the faint sound of her heart beating and the occasional muted whimper and...

She looks around. She’s undressed. Not naked. Just her dress is gone. She’s posed on the swing in her sheer pink panties and matching bra. And something new. Something she doesn’t remember putting on. A collar. She can’t see it, but she feels it. It feels like rough leather and a buckle at the back of her neck? If she had a mirror...

Her arms are raised. She grips the ropes above her head, stretchy material wrapped around her wrists so that her arms are secured in this position.

“Where...?”

“I’m right here, pretty girl.”

She feels the drop again. That wonderful welcome drop that pushes aside everything but the good feelings. The good thoughts. The desire to be a good girl for Laura...

“What happened?”

“You went to sleep for me, ” Laura answers as she moves around behind and gently places her hands against her bare back and pushes so that she begins to slowly swing.

Katy relaxes, a smile on her face. Her sister’s touch feels nice. Loving. She kicks her legs a little, her feet brushing through the rough grass, giggling as it tickles her soles.

“I have a surprise for you, needy girl.”

Katy moans as a trigger takes hold and...

“Oh god...”

Something inside of her begins to vibrate. Laura put... a vibrator in her... while she was asleep? She remembers this... it’s on low. She suddenly remembers how intense it was the last time. Funny how she’s forgotten about that until now. How her sister kept turning it up with her phone... how crazy it drove her as she begged for her to stop... or not to stop... how it turned her into a mindless drooling needy little slut, begging her to let her cum. How she cried and cursed and screamed as she was edged for what seemed like hours. Edged and cruelly denied. Tortured... She remembers how she’d told her ‘no’ over and over as she slowly lost her sanity. And she remembers how she’d been told to forget. To bury the memory... until now.

Hunger and desperation well up deep Inside of her. She feels her pussy making a mess all over the wooden plank. Her clit swells, her nipples tighten, drool coats her lips and runs down her chin.

“Please, ” she whispers as Laura gives her another gentle push, sending her slowly swinging as she trembles and shakes and whimpers as the toy vibrates mercilessly inside of her.

She’s met with a giggle as the vibrations intensify, spreading through her. She can almost feel them in her clit as she begins to buck her hips, fucking the air, unable to stop herself.

“You are such a slut, Katy.”

“I... I need...”

“To cum, little sister?”

“Yes, ” she wails, rubbing her thighs together, trying to get herself off however she can.

“Sorry. Not today. You haven’t earned it.”

“Please. I’ll do anything, just let me... “

Laura chuckled as she ran her fingers through her sister’s soft hair. Her little sister, although not by much. Four years. Looking at them, side by side, people sometimes mistake them for twins which amuses both of them... same honey blonde hair. Same pale blue eyes. Same slender build and small breasts and perfectly rounded bottom...

“No. Today your just my plaything.”

The vibrations got stronger again

“My helpless little sexy toy.”

And again she feels the buzzing toy inside of her intensity.

“My sexy little fuck toy.”

Saliva runs down her chin and onto her tits. Her cunt drooled a river of sticky warm juices all over the seat of the swing. Her nipples ached as if they might explode.

“Oh my god, I can’t-“

“Nap time.”

@

“Wake up.”

Katy’s eyes crack open and a whimper escapes. She’s belted into the passenger seat of her sister’s car, dressed in a sheer pink bra and matching panties. They’re both damp. Not just damp. Soaked. She wonders what happened to her dress. Her nipples ache. So does her pussy. The last thing she remembers was... they were going to the mall. Laura wanted some new books and a dress...

“I had a dress on...”

Laura glances over and smiles enigmatically.

“You did.”

“What... where?”

“It’s in the back seat. You should probably put it on before we go inside.”

“Inside?

“The mall, silly.” Laura laughs. The sound of her voice sends shivers through her younger sister.

“We... oh. That’s right. I remember now.”

“Is that all you remember?”

“I...”

Katy pauses and searches her memories. She vaguely recalls... the thread is lost. She shrugs if off.

“Never mind.”
