You or someone you know find a bodysuit device

This choice: Insist on putting her on  •  Go Back...
Chapter #9

Pissy Li'l Sis, Spicy Big Sis

    by: Nostrum Author IconMail Icon
As tempting as it may be, you know she’ll skimp on her promise – as always. If you let her choose, it’ll probably be to get back on one of her enemies – something that’ll benefit her, not you.

Thus, you stand firm in your choice. “No. You spent time as me, it’s only fair I spend time as you.”

“Why!?” she whines. “What would you get from prancing around as me?”

“Well, you spent time with Jimmy, no? Time I could’ve spent with him. Speaking of that – I know you told me something about having my mind, no? That being the reason you beat Jimmy at games?”

You know you cornered her. The look of a deer facing headlights is unmistakable. “Uh... Just so you know, I don’t remember any of it!”

“Why should I believe you? You’re smart – maybe you’re keeping some details on your diary. Y’know, for when you wanna screw me?”

“I wouldn’t...!” You see her fierce leer dissolve as she hangs her head in shame. “Should’ve thought about it.” She pierces your chest with her finger, growing feisty again. “But I wouldn’t do it anyways!”

“Think of this as a trust exercise,” you argue. “Say - next weekend, I put on you, go to Jess’s house or any other of your friends, and try to pass off as you. Like I said – it's only fair.”

“Fine,” she says, dejectedly. “You win.”

“Also...” You extend your hand, wriggling your fingers. “Hand them over. I found them, so they’re mine.”

With a defanged pout, she stomps her way into her room. You hide, fearing she’ll use the pens in retaliation, but to your surprise, she complies, handing the black pen. “Unlike you,” she states, “I’m not petty.”

“Who said I was?” you say, snatching the pen, only to notice Tina snooping in.

“Alright,” she warns with a stern tone, resting her curled fists on her waist. “What’s going on with you two?”

“Davey wants to take my pens.”

Why, you little...! You know bickering back won’t work, so you try a smoother approach. “Your pens?” You show the black one to Tina, cooking up an unlikely story. “These are Jimmy’s. They’re trick pens – you know, he loves his pranks.”

“They better be harmless.”

“Well, they aren’t.” You stealthily glare at Claire while telling so. “That’s why I asked to borrow them. His aunt gifted them on his birthday – they’re like tasers or something.”

“And you’re arguing because?”

“Because she found them, asked what they’re about, and now she's trying to steal them.”

“I’m not!” Claire points at you, fuming. “Sis, he’s lying.”

“Just look at it,” you say while giving Tina a closer look. “Last I know, she’s not into calligraphy.”

“Who says I’m not?”

You click the black pen – away from everyone, of course – and call her bluff. “See? It’s got no point. But if she were to point it to me, I’d get a shock.”

“Tina, he’s lying.”

“Prove it.” You hand the pen to Claire, then extend your arms. “Take your best shot.”

You almost grin as your younger sister desists, prompting Tina to side with you “Claire, stop pestering David. You’re not a little girl anymore. I don’t want you grabbing stuff that isn’t yours.”

“Alright,” she mutters – a big mistake, knowing Tina. “Friggin’ Davey...”

“What did you say?”

“I said it’s alright! Geez – I dunno what Davey’s interest in those pens are. They’re stupid anyways.”

“You said they were yours.” That chills Claire’s spine. She’s screwed, but that doesn’t mean you’re stepping away unscathed. “Look - I got a test this Tuesday. If you’re gonna bicker, do it wherever I can’t hear you. If any of you bother me, I don’t care who owns the pens – either of you, or Davey’s friend Jimmy - I’ll throw them on the compactor truck myself. You hear?”

“Tina!”

“Claire, I mean it. You know I can do it. Anyways...” She stretches her hand, beckoning. “I'll hold to the pens for a while.”

“How about ‘til Monday? Jimmy told me to keep them until then.”

“And can you tell him to grow up? You two should be thinking about your future careers, dammit – not stupid pranks.” She points at Claire, scowling. “The same goes for you.”

You glare at your younger sister one last time, taunting her. She says nothing, handing the other pen to Tina, who repeats her warning. “Come Monday, I don’t wanna see them. No bickering, no complaining – you return them, and if I see them, you know where they’re going. Have I made myself clear?”

“Oh yeah, sure!” You say with your fakest smile. “They’ll be with Jimmy by Monday.”

Tina points at you both before leaving. “Alright. You’re warned. Don’t bother me, alright?”

As she leaves, Claire scowls at you, and you twist your victory with a whisper. “One day. That’s all.”

--

It’s Friday, and you’re finally going to cash in on your prize. Nick won’t be there – not like he ever is – and neither will your parents. Your dad was invited to a business lunch – a fancy, formal one – and will bring your mother along, meaning they won’t return until almost midnight – enough time for you to have some fun.

You’re on your way out of school, and you feel you could use the “vacation”. You're stressed by an article you need to write for the school newspaper, and you feel Claire’s mind could give some ideas. Everything’s set, and you make it very clear to your younger sibling. “Just so you know, I’m calling it.”

“What?”

You snort. “My ‘Claire’ day, of course.”

“What!? Today? But I was planning to--”

“I had plans last Saturday.” (You lie, of course, but deliberately, to dig the knife deeper.) “Like I said, it’s only fair.”

“You better not screw me up, or else I’m gonna--”

“I promise I’ll take good care of you – I mean, when I mean fair, it’s fair.” (And by fair, you mean you’re not going to play with her body. As tempting as it may sound, you’re not a pervert.)

“You better.” She sighs, pulling the straps out of her bookbag. “You could’ve helped me get one over Krista, but you insist it has to be me, so...”

You’re glad you’re older than her, as you can play the big brother card. Claire speaks of an incident two days ago where Krista Mayweather, her sworn rival, humiliated her in front of all school by spilling cranberry juice on her blouse, making it look like an accident. She was on a foul mood that day, and between classes, she intercepted you with a plan.

“Like I told you back then,” you remind her, “if you do it, she won’t learn the lesson.”

“But she’ll humiliate herself!” she insists. “And because she doesn’t know, she’ll--”

“She won’t learn the lesson,” you stress. “Claire, you’re smarter than that. Besides, what you’re lacking on chest, she lacks on hips – and guys like those more.” (And you're not lying – she’s well on her way to inherit your mother’s hips, just like Tina.)

“Yeah, but until high school ends, she’ll--”

“Claire, high ground.” (That’s what Jessica said to make her desist - “keep the high moral ground”.) “You’re still growing – what if she gets stunted and you end up having the better body?”

She looks at you, perplexed. “You mean it?”

“You’re still growing up, Claire. Here,” you point at her chest, “here,” pointing at her head, “and here,” you finish as you run your finger up her spine.

“Davey! Stop it!”

“I’m not making fun of you!” You comfort her. “It’s true!”

“Davey... You’re not telling me this to make me feel good, right?”

“Of course! What – you need to get into my mind once again to prove it?”

She groans, and you laugh. “I have half a mind to try it, y’know!”

You throw your arm around her shoulder and shake her up. “You should learn to take a joke once in a while. Besides – if you don’t believe me, believe Tina. She’s the one that said it before I did.”

“Yeah, well...” She sighs, biting her lip. “Doesn't feel like it. You all treat me like a little girl.”

“Tina sees me as a little kid too – doesn't matter what I do. As for me...” You groan with unease. “You can get into my nerves with your attitude, to be honest.”

“I can say the same about you,” she says, stopping just as you’re reaching your house. “Y’know, maybe it’s good you spend some time in my shoes. Maybe it'd help you understand how I feel.”

You nod and smirk. “Sounds like a good idea. I mean – you understand why I like video games, right? Maybe I can understand some of your own quirks too.”

You pull your keys as she tries to stop you. “Wait. You’re serious?”

“Yeah.” You slot the key in and turn, stepping in. “Seems like the best way to use my--”

Upon entering, you feel something’s off. The curtains are shut, barely letting any light; there are clothes littered around, a hint of a briny scent wafts through your nostrils, and you hear moans and groans from the second floor.

“Eugh!” You look at Claire, her nose wrinkling as she follows you. “You thinkin’ what I’m thinkin’?”

“I dunno, but...” You walk carefully, trying to make no sounds. “Stay close, and watch my back.”

The two of you slowly make your way upstairs, noticing the sounds come from Tina’s room. They're not pangs of pain, and as you sneak in and check the open door, you notice why.

It mortifies you, because Tina rarely leaves her door open, never when naked, and even less when shoving her fingers so deep down her pussy that she’s hitting notes as if she sang in opera.

Claire pulls you back, whispering between gasps. “Jesus! She’d never be so brazen! What’s gotten into her?”

“I dunno, but...” She’s right. Tina would never behave like this. Something – or someone – must've gotten into her.

But that’s impossible. You have the pens on your bookbag - you hid them on your locker Monday and Tuesday, then on your room and bookbag afterwards.

You flinch as you hear her moans. It’ll be only a matter of time before she figures it out. You need to act – fast!

You have the following choices:

*Pen*
1. Check the pens

2. Tell Claire to check the pens

*Pen* indicates the next chapter needs to be written.
