Golden Rule

It was just a joke, a bet that you'd wear a shock collar for your big sister if she bedded your mutual crush before you.

It stopped being funny when she turned the voltage up.

"Come on, what's the golden rule?"

"Do unto others as you would have them-"

Electricity lances through the skin between the two terminals of the shock collar around your neck. Your sister's wicked laugh is so shrill in your ears that it's nearly as debilitating as the shock. "No, no, puppy, wrong again!"

You know what sentence Fade wants, the light bulbs surrounding its placard in your head are sparking and flickering on and off. A stupid edgelordy joke she picked up back in middle school to mock your strict adherence to your moral code and never dropped.

But fuck that.

Unbidden, you repeat it again: "Do unto others as you would have them do-"

Fuck! Your teeth bit into your tongue at the shock this time. You stare up at your big sister with obvious loathing. You're trying, you've been trying to hold to your beliefs for ten minutes, but the sparks in your head keep obscuring your most core moral tenet, and the fresh blood in your mouth tastes as red as her hair.

It was a joke at first. A bet where you'd have to wear a shock collar for a day if your big sister could bed your 'mutual crush' at the house party first. You didn't even come up with an alternative prize if you won instead, because your sister was your real crush, and you magnificently 'blew your shot' by spilling your drink all over the white dress of the target right when Fade walked by.

A wandering partygoer looking for the restroom caught you touching yourself outside the door while you listened to them fuck, and your sister laughed your beet-red face out of the building when she returned to the kitchen and heard what you'd been doing.

You still got what you wanted even with the embarrassment. She put the collar on you and the first shock gave you enough masturbation material for a month, but the fact that it made you moan and go red in the face was enough evidence for your sadistic sister to realize that it wasn't a 'punishment' for you. She immediately kicked the power setting on the remote up past the threshold that felt good, and she hasn't shown you an ounce of mercy since.

A headache is starting to pound in you, and there's a pressure building to just make her stop, no matter what it takes.

You'd be turned on by the smoky way she intones "One more tiiime, puppy, the golden rule. I know you know it." if your brain didn't ache. Maybe you're still turned on by it anyway. The blood in your head hurts, the blood in your neck is terrified of electricity, and the blood between your legs is telling you to listen for a totally different reason. "Do unto others as-"

She twitches with the remote and you flinch, hard. You look up at her gleaming hazel eyes, and… fuck.

"Do unto others… first." Your gaze dangles down onto the floor as one of the strings of your moral net frays and snaps.

"Gooood puppy!" Fade swings one foot up from where she's been dangling them off the dining room table and jabs you in the nose. It sparks tears in you, and they're watered by the fact that she's right when she says "And now puppy is going to do unto Sephora and shoplift the Dior makeup she was 'too broke' to buy her big sister for her birthday!"

Fuck you Fade-

It's fine, it's Sephora, it's all overpriced garbage anyway.

Fuck you Fade-

Do unto others, do unto fucking capitalism, it's fine, fuck Sephora-

"Can I help you find something?"

Your head jerks away from the products you've been staring at with dread. "Oh! No, I'm just comparing shades."

"Let me know if you need anything!"

Fuck, that's bad, someone saw me.

One pitiable wage-slave's seen your face now, and the building has enough security cameras to make a bank vault blush. You have two choices:

Stuff $260 worth of disgustingly overpriced designer makeup in your bag and burn $20 to buy some trash to avoid suspicion…

Or stuff everything in your bag and leave without paying at all, so that you can fill your gas tank enough to not take the bus to work tomorrow.

Fuck.

You yank the $20 out of your wallet and pray to whatever gods are listening that someone is off sick tomorrow and you can make decent tips in their place.

You dump the paltry contents of your purse right on Fade's lap when you get home, and of the five bottles cascading over the couch, she picks up the decoy with disdain. "What's this, Lawless-"

You snatch it away. "Not that one." She greedily picks up another bottle, and a grin immediately lights her face. She croons "Gooood puppy!"

If it were 'Good girl' maybe I wouldn't hate you-

"Disgusting puppy gets its disgusting treat!"

She turns to stand off the couch and snags a finger in your collar to pull you in for a kiss. You startle and jerk backwards. "What was that?"

She smirks. "I know what you want. You weren't outside that door for Zane."

You go crimson. "I…"

If she already knows, then-

"Can I have another?"

"No, I don't think so."

"Damn."

"Hmmm…" She puts a finger to her lips and makes a comical thinking expression. "Well, maybe if you get me something else, then I can put up with your sick sister fetish." Dread flickers over your mind before she continues "I want the bottle of Dom Pérignon from the top shelf at your work."

Black and green label, so high you'd need a ladder to get it down. "No. No way." You could wait tables somewhere else if you got caught, but what actually matters is that "Davin's bartending, he would be on the hook if that went missing."

Fade cocks an eyebrow and a hip at you. You shake your head again. She points the remote at you, and you quickly protest "He's a good guy, he doesn't deserve it, he helped me pay to get my car towed last month!" You still haven't paid him back.

Your big sister takes a step forward and pokes the remote into your chest with a growled warning "Puuupppy…"

You smack the remote away from your chest. "No fucking way I'm not-AH!" Your knees hit the floor hard, and your hands blithely try to coax some air back into a throat that got shocked empty.

"Bad puppy! You made up for my birthday, now you're going to get me something I actually want!"

As you try to put your thoughts back together, you wonder why you ever had a crush on her. She's such a bitch. It's fucking over, you're done, this has gone too far-

You lift your head, and, well, fuck, there it is. Plaid schoolgirl skirt, white top, no bra, like she's trying to seduce her teacher. It wasn't ever about her personality, and you fail to keep your eyes out of her skirt - white panties, like a god damn pinup.

"Puppy." Your throat instantly seizes up in fear, but it relaxes at the offer of "You get this, and you can look."

You wait too long, and she points with the remote again, so you stammer out "Fine! Fine, fuck."

It's the end of your shift, and you got lucky that you picked a stylish enough shock collar that it could pass for a chunky choker. No complaints from customers, and you only had to deal with a friendly ribbing from Davin before he clocked out early. You reach around and try to pry the lock off again, but within moments the anti-tamper feature shocks your fingers.

Fuck! If I tell anybody I'll seem like a fucking moron and she'll deny it and hide the remote, and if I keep going I'll be a hypocrite that fucks over someone that doesn't deserve it.

Your brain starts to grope around for justifications, hard.

He already helped with the tow and he didn't even ask me to pay it back, he's probably got enough to cover it. He'll be fine.

You can feel murmurs of decay in your chest as you head back inside and check for witnesses. The closing waitress is rolling silverware and watching an ASMR video on her phone, and your manager will be locked in with frozen fish for another twenty minutes. Lucky.

As quietly as you can, you shuffle the ladder out from next to the beer fridge and climb.

Your 'prize' is filthy with dust, and you climb down carefully without leaving any marks three hundred dollars might be enough for your boss to check for fingerprints. You stuff the illicit item in a paper bag and the ladder back where it came from, but a set of bottles catch your eye in the fridge. Your neck buzzes with a phantom electric shock and your head swims with shadowy thoughts.

If something's going to go missing, it'll be less suspicious if it seems like things just got inventoried incorrectly…

An invisible force stops your hand before you touch the door.

He's already going to be in trouble, this will just make it worse.

But… he's probably going to try to throw somebody under the bus for this, and it might be me, so I might as well get something to help me forget all this. If Davin's going to blindly try to fuck me over anyway, then I might as well get to actually drink some of what I steal.

"Puppy!" Your sister rushes to you the second you're in the door to yank the bottle out of your bag while you fumble with the handful of soju bottles left and try not to drop any of them on the floor.

With zero gravitas, Fade rushes into the kitchen and you can hear the cork on the bottle immediately pop. You follow her and crack one of your own drinks while you watch her root around in the low freezer for ice cubes far in the back. Your eyes trace up her gorgeous legs, envious that she's kept her tone since quitting gymnastics, up to her ass, admiring the curve and thinking of what your hands and teeth could do to it, and-

There it is.

Unguarded- or, basically. Though you'd rather stick your fingers into the waistband of her tight shorts, you could reach right into her back pocket and take the remote for the shock collar.

You take two steps forward. "Hey Fade, grab me some ice too, I want to share." She wiggles her ass. "I'm not sharing." You continue stalking forward while she shuffles bags of frozen vegetables out of the way to try to find more cubes. "You're going to be wasted."

"As if, my tolerance is super high."

You manage to pinch the little device out of her pocket right as she stands up, and you dance backwards out of her reach with it held in the air. "Fucking finally, you bitch. I never should have given you this."

She throws her ice into a glass and rolls her eyes. "Give it back." Your indignation at her certainty about its return could etch you into Mount Rushmore. "No. Why would I?"

She rolls her eyes again and her whole head too, then she suddenly darts a hand out and tries to snatch the remote out of your hand. Not quick enough, and you laugh. She puts on yet another dose of dramatic exasperation and painfully flicks your clavicle. "I guess you don't want your treat then, stupid puppy."

That makes you freeze - smothering your self-loathing all the way home pushed the reward out of your mind too. "What treat?" Fade pouts and holds her hand out, but you don't move. "What treat? You never said what it was?"

She waves in the air dismissively and pulls out her phone to flash the screen at you: a picture of herself, nude above the waist and making an exaggerated ahegao expression that instantly makes various indiscrete places on your face and body flush with intense blood flow. "This is your treat, I was going to send it to you." You lick your lips, and she shuts the screen off on her phone and points. "Give it back first."

Fuck.

That picture was unbelievably hot, and you only got to look at it for a tantalizing second. "Show me that you're about to send it. Draft the message." She sees something in your eyes, so she swipes to unlock and queues the text up. You take yours out to confirm, and she plucks the remote away as soon as it dings. Your eyes greedily rove over the picture - black choker, dual braids, she even put eyeliner, eyeshadow, and mascara on for it.

Hot damn, you need to get somewhere private-

"Fuck!" Your phone leaps out of your hand when she buzzes your collar again, and it clatters to the floor. Before you can complain, Fade pushes you against the wall with an intensity in her eyes totally separate from the disdain she held you in moments ago. "I knew you'd take it, you fucking pervert. That's disgusting. I bet you were smelling my dirty panties for years before that party."

You stammer out "I, never went through your laundry-"

She steps back. Zap. "Liar!"

"I didn't!" Fuck, did you? Was that just something you imagined doing? Considered doing? It's getting hard to feel out the lines between what you think you did, and what you actually did.

While you try to figure out which of the fractal mirrors in your head is showing reality, she pours a full glass of her expensive alcohol and callously throws it back without seeming to taste it. After a few moments you decide, you definitely didn't perv on your sister's dirty laundry, you just thought about iiiiiiii-

Your eyes roll back in your head at the gentler electricity running through your neck, and you slump back against the wall and moan. This is the 'joke' you wanted when you let your sister collar you, and she was supposed to laugh genially like she is now, and not like the psycho she's been lately.

When you run out of breath you look down from the ceiling to see her with a hip cocked and a smirk on her face. And hell, is she biting her lip? "You like that?"

You nod.

"Are you a good puppy?"

"Yesssss" Hell, if she'd been this playful, maybe this could have actually been fun.

In the center of your hazy vision she steps back another foot and, to your excitement and shock, undoes the fastenings on her shorts and lets them fall to the floor. Before you can even stammer out a question, she makes her demand: "I want Haile's first place gymnastics trophy."

You go pale and your mouth snaps closed. There's no way you're stealing your best friend's trophy after she trained so hard that she was out sick for two weeks after the competition. "What? No way, what the fuck is wrong with-"

Shock! "Bad puppy!" This one was way too strong to be fun, and you have to fight through teeth that are starting to chatter with jumbled nerves. "She earned that, you don't know what she went through-"

"I earned it! I'm better than her, the judges just picked her cause she's anorexic!"

"That's, not true, she worked hard and she deserved it-" The collar sparks hard, but then it evens out into the 'fun' range again. As your vision goes hazy and golden, your sister slips her fingers into her panties. Your mouth drifts open, and you're a notch from drooling.

"Get it for me and you can touch."

Pleasure drunk, you start to stammer out "N,n-uh, no…"

Fade starts to slide her fingers in and out of herself while she tweaks the dial on the remote to hurt you more. Something that frayed in your mind at screwing over a coworker starts to completely tear, and you can hear every fiber of the paper coming apart as the pain increases. It's hard to resist justifying what you're going to agree to.

The competition is already over, she already won, who even looks at trophies, fuck-

"Okayyyy…"

Your best friend's unlocked back door opens as silently as ever, and when your fingertips find the polished marble columns of the trophy in her room, the anticipation of touching your sister is evaporated by an ache deep in your chest that carves through your heart. Tears start to wash down your face as you hear your own voice echo:

'Every step away from your values takes you further from the person you think you are.'

You can still feel the rain pouring through your hair the night your best friend showed up at your house sobbing. You held her close until you were both soaked, and when she finally told you that she'd cheated on her boyfriend, you pulled that line out. You meant it. You'd never said it before, but you've lived by it every day since then because it's true to you.

So has she. She confessed her mistake to her boyfriend, and… against all odds, they worked it out. Stronger than ever. He was the one who nursed her back to health after the gymnastics collapse. He's the one she meets every day after school. He's the one she's going to marry.

He's the one who stands beside her. Her best friend.

Not you any more.

Because you helped her make amends.

Your fingers clench around the trophy, and the glue holding the marble to the base feels ready to crack.

She's going to leave you someday. She's going to walk down that aisle and he's going to put a ring on her finger and he's going to take her away to Germany and you're never going to see her again.

Do unto others first.

You stuff the trophy in your backpack and zip it up, but then you notice a handful of crumpled five dollar bills sticking out of a purse on the dresser.

Fuck it. She never paid you back after your phone fizzled out in the rain that night.

Fuck you Fade fuck you Fade fuck you Fade fuck you-

"Yes, yes, yes yes yes yes, puppy!" As soon as you're in the door your sister pushes you onto the couch and plucks the trophy out of your hand. Little sociopathic laughs bubble out of her while you stew in resentment at being made to act so reprehensibly. Her eyes drop back to you, and she tosses the prize onto the couch. Your heart and stomach are lanced by spikes of painful excitement when she climbs onto you, straddling you with your face six inches from her chest. "Trashy puppy gets its filthy treat!"

Your breath is thin as you lift your hands and slide them under her shirt, but she leans back and smacks one hand away, her other lifting the remote into the air. "Bad puppy!"

The shock burns that wicked delight at punishing you into your brain, and both your hands drop to your sides. You complain "What?"

"Did your big sister say you could get under her top?" She tisks and wiggles a finger in your face. "Stupid, stupid puppy." Her smirk could curdle the calcium in your bones when she grabs one of your hands and lifts it to her breast over her shirt instead. You raise your eyebrows and wait for her to shock you about it, but she actually looks vaguely excited. Tentatively you squeeze, and she wiggles the little black remote, but she doesn't press the button. You wait too long, and she squeezes the back of your hand to make you grope her properly. Her eyes are locked on yours, and with the way that she bites her lip, you can't help but feel your blood rush at the idea that she's enjoying this too.

Paranoid of another zap, you slowly lift your other hand to her chest and start to knead both sides in symmetry, and her breaths start to turn steamy. It isn't until she starts to push her chest forward in time with your squeezes to get you to inflict more pressure that you start to think that maybe, just maybe, this is going somewhere. Her eyes drift shut for a small moan, and you drop one hand down to her exposed thigh and squeeze there. She cracks her eyes open to smirk at you again, but then she closes them again and starts to moan louder.

You can already feel the potential electric charge between the terminals against your throat when your fingertips brush under the fabric of her skirt, but instead of moving them further up, you tuck them around to gently cup her ass. She reaches up and pokes you in the nose with the remote, finger right on the button, but after a second of staring she laughs and lets her hand drop beside her.

Pressure is starting to build in you that you're sure would earn you mockery or even a shock if you let any noise out, but you can't help but start to pant to match her as your face goes blazing hot and your eyes start to go hazy from arousal. You already got zapped for trying to tuck under her shirt, but you're already under her skirt, so if you slipped your hand under her panties…

Your heart skips a beat and your hand ceases its travel as soon as she speaks. "Are you having fun, puppy?"

Fuck, is 'yes' the right answer? It's obvious, but does she want me to say that?

You may be a stupid puppy, but you're at least trying not to be. "Yes?" Much to your chagrin, she leans back and steps off the couch. She seems to be delighted by the disappointment in your eyes, and she gestures with a finger for you to follow her as she stalks backwards across the room. Completely entranced by the possibilities in her smoky stare, you stand and follow. She finally reaches a spot where she can point down the hallway. "I want grandma's watch."

No.

Your grandfather gave her that when he turned 18 because he couldn't afford a ring. It's the thing that kept her believing that he'd come back after his parents sent him away for dating a girl two years younger. She spent the whole funeral staring at the timepiece in her hand instead of listening to the eulogy. She's forgetting things more and more these days, but the one thing she never misplaces is that watch.

The workers at Sephora probably gave your picture to the police. Fuck 'em.

Davin's probably going to throw you under the bus for the missing alcohol. Fuck him.

Haile's going to leave you for a man she betrayed. Fuck her.

Not your sweet grandmother, not her most cherished possession-

Shock! Shock!

You waited too long and she gave you a double tap. Your eyes are clumsy getting back to open and focused.

"Puuuuppy…"

You try to grab at the loose gravel of your remaining fortitude and start to shake your head-

Shock!

It goes blank for a moment. A few moments. You can't count, you're an etch-a-sketch with no magnets.

When you're back, you're staring into her eyes, and she worms her way into your mind.

It's fine, right? It's for her, for your big sister? It's okay? Your grandmother is going to die anyway. Probably even soon, maybe. You might as well do this now before she goes and dies on you.

Through a throat still trying not to spasm, you force out "O-… okay. I'll do it."

"Aha!" Sparks burst in her eyes almost as loud as they did in your head a moment ago. It's almost more torture to see her delight in your suffering than the suffering is itself, but her validation feels so good.

But you need more. You need the reward. Now.

…do unto others first…

You dart forward and smash your lips against your sister's. Before your eyes close you can see hers flare, and an instant later you can feel the electric shock kick in-

"Ah!"

Fade yanks her bright red face away from yours, both your mouths stinging viciously from where the electric current jumped from you to her. Though it's a fresh place for the pain, you've been adjusting to the torture for a week, and it's totally raw for her. Burgeoning tears threaten to spill out of her wild eyes, and she starts to stammer and gesture her remote at you. "Bad puppy! Bad pupp-"

You dart forward and kiss her again, just in time to make her zap herself through you. The fuzzy pressure in your head is being catalyzed by the electricity, and the pathetic whimper from your big sister pulls a voracious smile onto your lips. You can see fear bloom in her eyes at your expression, and when she limply tries to lift the remote to point at you again you close the space between you and push her roughly against the wall, pinning the remote between your hand and hers above her head.

She didn't manage to press the button this time, and you lean in for another hard kiss, this one delicious from the softness of her trembling and swollen lips.

Another. She stays still for it.

Another. There's something in her breathing…

Another. She twitches.

Another. She kisses you back.

You snicker at her. "You liked it this whole time, didn't you?"

"No-ah!" You didn't leave her enough clearance between your faces, and she whimpers again at the shock when she presses the button again.

Your lips are starting to go numb, but you murmur into her hers "You liiiiked it." just close enough for the threat of the shock to keep her trigger finger chaste.

"I didn't like it…" Her voice wavers, and it's clear enough that she's lying for you to consider it consent. Another kiss you wish your lips were more sensitive for, and she kisses you back immediately. All the hair raises on your body, and a tingling sweeps through you. You could have had her this whole time, all you had to do was do unto her, first.

Your body is lined with ecstasy as you start to slip your hand under her shirt, and her gasp is so delicious after days of being her playtoy. Your fingers rove over her bra for a few moments, then you slip them under the band to inch toward her breast.

Some vestige of emotional energy flexes in her, and you pull back for a second to let her say "No, bad puppy…" Her finger twitches over to the shock trigger, but you hold yours between her fingertip and the button, then lean in and reply so closely that your lips are physically touching. "Are you sure you want to do that, big sister?"

You can hear the last vestiges of dominance crack in her voice. "No…" She flexes her hand open and the remote is yours. You laugh into her mouth, wicked in your own right, but quiet and self-satisfied.

Finally free to separate the threat of your lips from hers, you move past her face to her ear. "Who's a good puppy now?"

"Y-… you…"

"Your little sister is a good puppy? And she gets to do what she wants to her big sister now?" You slide your hand up and over her breast in the crowded space under her bra with the tiniest of squeezes as a promise.

"No…"

You lick her earlobe and press the button at the same time, and she practically shrieks in your ear at the shock. Though the pain from both sensations is stark, you're starting to enjoy being a conductor to torture your sister with. She tries vaguely to wriggle free when you start to squeeze her breast in earnest, but all you have to say is "A-a-aaahhh" in her ear to make her go still again.

Free to indulge yourself, you coax hesitant moans from her with her breast and nipple, play at her throat with your lips and tease her gently with teeth, and then your hand dips down to her waist. She shakes her head with another fake denial, but from the way that she's shuddering and panting at your touch, you know you've won. You snag a finger under the elastic of her skirt and yank it down to pool around her ankles, and the squeak she makes at the exposure puts a ticklish delight in your chest.

God, I should have done this so much sooner. She was just begging for someone to dominate her.

You pull her off the wall and gently push her onto the couch, and her lack of resistance and the wet spot on her panties show you that she's ready for the next step. You turn the safety of your collar on with the remote, then unlock it and dangle it off a finger as you stalk toward her. "Faaaaade~"

Her eyes fill with apprehension as you reach around her neck to fasten the collar on her, anointing her with a kiss on the lips as punctuation that she doesn't return. You lean back and wiggle the remote in the air. "What's the golden rule, puppy?"

Dread and paleness spread across her face. "Do unto others first."

You shake your and overtly flick off the safety, but you don't press the button right away. "No, no, bad puppy!" You straddle her and position her thumb between yours and the button to trigger the shock, then you lean forward and whisper into her lips "Do unto others, as you would have them do unto you."
