"How did you find a costume that would fit me so-- so well?" Cerise asks, marveling at herself in the mirror. She fills out the bunnygirl costume perfectly. Just as you suspected, an outfit that was way too tight for Charlotte is just perfect for your dear sister. Her choker completes the pseudo-slutty look. You feel a bit weird knowing strangers from all around the globe will be ogling her, but you're fast developing an exhibitionist streak of your own.
Alex has finished hooking up the new PC, getting Cerise's new Twitch account ready to go, and arranging a couple webcams. Now he prepares a green screen backdrop and some cheap lights. Cerise's old gear from her prior livestream is finally getting its first use in over five years.
"Your turn," you tell Alex. You hold a bag aloft, the one with the outfit you've selected for him.
With shaky hands, he takes the bag. He opens it and looks inside. He shuts it again.
"I can't wear that!" He chirps.
"Why not?" You ask.
"That's a succubus costume!"
"So?"
"I can't be a succubus! I'm a boy!"
"Cerise is a human being, but she's dressed as a bunny," you counter. "And you've dressed as a maid plenty of times. What's the difference?"
Cerise takes the bag and looks inside for herself. She whistles. "I like it," she affirms.
"I-I'm not sure about this!" Alex says. "Maybe we should do a little advertising and outreach and stuff before getting our first stream going--"
"Take the arms," you tell Cerise.
"Wha--" Alex begins. He loses his wind as Cerise grabs him under the arms and restrains him. You strip him to his skivvies as he writhes and resists. His lithe body is flushed all over, but there's a tent in his boxer-briefs. "Should he wear panties too?" You ask Cerise.
"Absolutely. Verisimilitude demands it."
"Nice vocab. But I was thinking he should go nopan. That's more true to the succubus aesthetic, isn't it?"
"Ohhh," Cerise breathes. "I like the way you think."
"Guys--" Alex says.
But no use trying to protest. You peel Alex's underwear off, leaving him naked and ashamed before you. His leaky cock tells the truth. He likes this kind of treatment, the slut. Cerise hands him the costume and commands him: "put it on." The tone of her voice leaves no room for backtalk. She isn't fucking around. That's the way you have to be with Alex, sometimes. He struggles to get himself into the too-small outfit, the latex hugging his body tight. It puts what looks like a lot of uncomfortable pressure on his straining dick. He regards himself uncertainly in the mirror, poking his index fingers together. His cock throbs through the material, and it makes his tail with its heart-shaped end bob a little bit in the air.
Your own cock is getting hard, too. The sight of Alex in that whorish costume, not to mention your bunnygirl sister with her cleavage showing and pale thighs contrasting against the dark pantyhose, makes your heart swell with contentment. You made some good selections. You've got great taste.
"How are we going to get viewers?" Cerise asks. She affixes the surgical mask to her face that is supposed to preserve the patina of anonymity. She does the same for Alex next.
"You've got a built-in base of subscribers, don't you?" You say.
"Who-- oh. Oh, no. No fucking way."
"I mean. We won't say it's you. We'll just imply it. And then let word of mouth build your subscriber count after that."
Cerise rubs her forehead. She doesn't like the prospect of it, but it's definitely the best method for getting eyeballs on the new show, fast.
---
You stand off to the side and watch as Cerise and Alex sit silent and motionless in front of the cameras. You've just put the word out on /csg/ -- a single anonymous post of "holy shit... is Cerise on stream again?" -- plus a link.
The view count is rolling up and up. 20, 30, 50, 100... it always blows your mind how many losers are obsessed with her. Hopefully the sudden surge in popularity right out of the gate will slingshot Cerise into a position of prominence on the platform.
"Good afternoon. Sakura Dokuhaku here. Let's get started, hmm?"
The screen-in-screen setup shows the desktop as well, the tools arrayed and ready, and tonight's surgery victim -- a Tickle-Me-Elmo.
"My assistant Besuto will help," Cerise says. "Today we'll demonstrate some basics of how to interface an audio jack into a toy like Elmo here, so you can directly control the soundboard... a very elementary operation, but quite painful for the poor subject, I'm afraid..."
"Muahaha~" Alex laughs, playing up the demonic angle. He's slid into his role as succubus quite nicely.
/csg/ is going nuts.
>WHAT THE FUCK. IT'S REALLY HER. WHO THE FUCK IS THAT NEXT TO HER?!
>Are we sure it's her, guys. It's so suspicious that some anon just suddenly dropped the link as soon as she started...
>Shut the fuck up fag. Of course it's her. Are you blind? You can't even recognize the Goddess?
>This is the best day of my life.
>I want to circuit bend with Cerise! I really want to!
"Scalpel," Cerise says.
Alex hands her a scalpel. She uses it cut the fur from the Elmo's back and peel it open, like vivisecting a frog.
"That tickles!" Elmo shouts. "HAHAHA!"
This is, as always, horrifying.
"Phillips head," Cerise commands. Alex hands her a jeweler's screwdriver, and she begins to remove the back half of the hard plastic case of the toy's body. Though Alex is wearing a surgical mask, you can tell how broadly he's smiling. This is like a dream come true for him.
>Besuto. Alex Best. She's streaming with DBA's CTO.
>You've got to be shitting me.
>Are they together? They look awfully, uh, friendly...
>(Alex_Best.jpg) Oh my god. Pack it in, boys. This is the man who just cucked us.
>Don't care! This is hot as hell.
>Literally fapping and shaking and cumming and shitting right now.
Cerise is soldering new connections onto the toy's circuit-board and Alex pulls out a small synthesizer that will somehow play a part, too. But you're hardly paying attention, you're more focused on the comments in /csg/ and the Twitch chat. They're flying by so quickly that you can't keep up. The leering, the gnashing of teeth, the sheer level of thirst, makes you simultaneously smug and mad. Smug, because they're all losing their shit over her, and mad, because /csg/ always pisses you off with their graphic descriptions of what exactly they'd like to do to Cerise.
Right around the time the insufferable tripfag known as TCG starts going on a diatribe about how the girl on stream could not possibly be "the Goddess" and how anyone who says she is, is a shill who should be banned, and how Cerise is obviously a pure and untainted girl who would never even hang out with a man, let alone have a relationship with one, you've had about all you can stomach. It's time to exact a little revenge on the denizens of /csg/.
You stroll into frame.
"Ala-- what are you doing?" Cerise hisses.
You rub her shoulders. "Let's give them a show, Sakura. Introduce me, huh?"
Due to the positioning of the webcams, you're only visible from the waist down, but that's just fine for what you want to do.
Cerise squints at you. "You're gonna get me banned from Twitch, asshole."
"We can start our own website. Just call this a preview of what's to come..."
Cerise turns towards the blinking red light of the main webcam again. She clears her throat. "This is Shiro Dokuhaku. He knows absolutely nothing about circuit bending, so you'll have to forgive his presence..."
You stand there watching from over Cerise's shoulder as she diligently continues to work. Alex casts a few frightened glances back at you -- he has an inkling of what might be brewing here, too.
You scroll the thread on your phone.
>IS THAT
>Oh my god. Oh my god. Oh my god.
>AAAAAAAAAA
>PURITYFAGS BTFO
>It's not Cerise, you fucking morons. Holy shit. The bridge of her nose is completely different. Her ears don't match. The haircut isn't the same. You people are LITERALLY retarded. Holy shit.
>Is that her brother? Is her brother giving her a fucking shoulder rub in a bunny costume?
>[INCEST INTENSIFIES]
You pocket your phone with a smile. They haven't seen anything yet.
You reach down and cup one of Cerise's breasts. The material of the bunny costume, the way it forces her tits together, has made them perkier and firmer than usual -- but the skin has a nice, supple give to it all the same. Cerise draws a sharp breath, but she doesn't tell you to stop. She just keeps working. Taking that as permission, you run your hand around the curve of her breast now and get your fingers underneath the fabric concealing it. You grope her shamelessly.
"Ala-- Shiro--" She whispers. She wriggles a little in your grip and forces your hand out of her bustier. "I'm sorry, everyone," she says. "My little brother is a pervert."
This is already lewd enough to get the channel booted from the site, so you're just waiting for the moment it happens. Growing bolder in light of that, you try to entice Cerise by groping Alex now instead. Alex mewls and whines as you run your hands along his flat chest and tweak his nipples through the thin material of the succubus costume's top. Despite your molestation, the two are as industrious as ever and now Alex is connecting audio jacks to the splayed-open Elmo doll. Cerise, eyes half on the workbench and half on the liberties you're taking with Alex's body, begins to fiddle with some knobs, and the toy starts to make random, high-pitched warbling noises.
"I think this demonstration should be more than good enough," Cerise says to the camera. "As you can see, the operation is a success and the patient is transformed..."
"Nnn~" Alex mumbles as you get your hand into his costume now, too. You squeeze his bare chest and he arches his back in his chair appreciatively.
"I think that's enough for today's stream," Cerise says.
"Do your patented sign off, then," you tell her.
"Which is what?" She says skeptically.
"The one with my cock in your mouth."
Cerise's eyes bulge as you unzip your fly and pull out your throbbing cock for all the world to see. You give her no time to react any further, as you push it behind her surgical mask. Her lips are wet and feel nice against your achingly hard cockmeat. Though she isn't totally pleased at what you've done with her stream, she can't resist the sight, smell, and taste of your dick. Her eyes droop as she stares down her nose at the bulge it makes in her mask. Alex's eyes droop too, as he watches on, jealous.
Cerise decides to roll with it. She plants a loud wet kiss on your cock. "Thish is Shakura Dokuhaku," she says, muffled. "Shigning off!" She winks and holds up twin peace signs as she kisses and suckles on your dick, and you thrust your hips a little to help her along.
She doesn't have to kill the stream because Twitch does it for her. The feed goes dead and the channel closes with a message from the site saying that it has violated their ToS.
No matter. You've got your dick between your older sister's lips and that's what counts. Cerise is still holding her hands up for the cameras, unaware that she's no longer broadcasting. She flicks her tongue repeatedly against the sensitive underside of your prick as she continues with the double peace sign schtick.
Alex has a bit more situational awareness. He takes his face mask off and gazes longingly up at you. "Ally... let me suck your cock too, please..."
Cerise blinks in surprise. "You're off the air," you inform her.
She laughs through her nose, and the little bursts of cool air against your dick feel really nice in their own right. She peels away her mask, too.
"Help me out," she tells Alex. "Let's suck him off together."
You sink down onto her bed. Cerise and Alex sit on their knees before you -- bunny and succubus, a perfect combination. You ruffle Cerise's hair appreciatively and grip one of the kinked ears, as the two of them get to work now in earnest. They make such an adorable pair with your shaft between their lips. They slide up and down in an alternating rhythm, so one is at the head while the other is at the base, then vice-versa. Their wet, slobbery tongues totally coat your dick in viscous drool that seeps down its length, over your heavy nuts. There can be no better relief than this. Occasionally, Alex stops to flicker his tongue lightly against your balls, then to suckle on them, and smile up at you.
You glance down and see that Cerise has both hands between her legs, pawing at the tight crease of her costume's crotch.
"Naughty bunny," you chide.
"Mmm," Cerise moans, low and sensual, a murmur of agreement. She pulls away from your cock with a wet plop. "Will you help my bunny pussy feel good, then?"
Alex traps your cock against his lips, his hand wrapped around the other side, and licks it with increasing vigor. He's so greedy with your dick. You curl your toes and groan.
Cerise stands, and grabs the back of your head, and pulls you into a desperate French kiss. You taste her mouth for the second time today and enjoy just as much as the first. As you make out, Cerise takes your hand, guides it between her legs, and beckons you to play with her. You rub Cerise's cunt through the material of her outfit. Even from outside, you feel its raw heat.
Alex, between your legs, starts to suck you off. He gets the head of your cock inside his mouth and then sinks down, down, down, gagging himself. You and your sister make out wetly as you enjoy the feeling of Alex's expert fellatio. He's such good little cocksucker. The best. You can feel the bubbles of his saliva popping at the corners of his lips as he slides up and down on you. He's practically gargling your cock.
"I wanna fuck you," you whisper into Cerise's ear. "I wanna fuck you so bad."
She caresses your hair. "I do too, Alabaster... I really do..."
You slip your hand under the hem of her costume and run your fingertips along her naked cunt lips. She shivers.
"I'm sorry..." she whispers. "But... but I..."
Alex is choking hard on your dick, but keeps sucking. What a doll he is. Anything to make you feel good.
You kiss her again. "We have permission, you know... Mom said it's okay, right?"
You fingers in her pussy are quickly dismantling the last of her resistance. She shifts her healthy thighs back and forth, tensing them, and increasing the pressure of your hand against her genitals. She moans.
"We've done everything else... why not let your little brother cum inside you, too?"
"Ungh..." she moans. That image definitely does something to her, something she likes.
"Besides -- you don't want to be a virgin at 26, do you?"
Cerise narrows her eyes. Even as you molest her, she disputes the accusation: "I'm not technically 26, you know... my time of birth was 4:21 PM..."
You crane your neck and look around Cerise, at her PC monitor. The current time is 4:10 PM.
"You've got about 10 minutes before you're officially a Christmas Cake, then," you say.
"Fuck you... oooh~" She tries to be hostile, but you tickle her clit, and that's all it takes to tame her again.
You nuzzle the side of her face. "If we're quick about it... I could blow my load in you before you turn 26... just saying."
She searches your eyes for a moment. You play with her clit some more and smile at her, nodding. There's no way she can say no to this... you've got her totally worked up now.
"You would cum inside your own sister?" She says.
"Fuck yes I would. There's no place I'd rather cum."
She kisses you all over your neck, your face, your lips. "You are such a fucking pervert..." she sighs.
"You are too."
She climbs onto the bed. Alex, taking his cue, releases your cock from the back of his throat with a wet gurgle. He smiles warmly, blushing, and watches from the floor at the foot of the bed as you join Cerise.
You get on top of her. The passion and force of your mutual kissing knocks her bunny ears askew and finally off her head entirely. You grab them and toss them aside. Enough of the costume. You just want to fuck your older sister.
"Are you... sure about this..." she asks.
"As sure as I've ever been," you reply. "God I want to fuck you."
She shudders. "Okay... okay, Alabaster..." With a kiss, she stutters: "f-fuck me..."
You tug the one-piece off of her, starting at the shoulders, and pulling down, like unwrapping a piece of candy. Alex is ever-helpful, and pulls the garment from off her legs for you, as you and Cerise passionately mingle your tongues and sigh into each other's mouths. You quickly strip free of your shirt and pants now too. And then there you are, Alabaster and Cerise Soliloquy, two siblings naked in each other's arms on the bed, ready to mate.
You line up at the entrance to Cerise's sticky pussy and enjoy the sensation of your cockhead spreading her engorged labia apart. They cling to your dick as if kissing it. You link hands with Cerise and stare deeply into her eyes. This is it: you push. And then you're inside -- you feel, for the first time, the divine sensation of your sister's pussy walls engulfing you.
"Ohhh" you grunt. "Oh fuck, Cerise... you're so tight..."
"No," she says, shaking her head. "It's just that... oh my god... you're so big..."
She wraps her ankles around your butt and draws you deeper. You lay your head against her collar bone, pressing your full weight against her body. Still linking hands, you begin to rut. It's fast and hard and needful, almost primal, but somehow tender all the same. This is 20-some years of pent-up energy releasing in one glorious explosion. You're fucking your older sister -- you're fucking her raw, lying on top of her in her bed, pounding her cunt into oblivion. And she loves it. You do too. Why did it take so long? You should have been fucking her for years. This is way too good to have missed out on. Her creaming pussy is the perfect shape for your dick, like two corresponding pieces tailored just for one other. Cerise's pussy was made to get fucked by you.
"Fuck me!" she breathes. She throws her neck back and her muscles tense. "Yes! Cum inside me!"
That's exactly what you needed to hear. Full permission from Cerise to get off inside her cunt. Permission to drop an incestuous load in her. Permission to sperm your older sister.
Your hips become a blur as they bounce up and down. Your fat prick saws in and out of her, and her squelching insides cling so sweetly to you as you stroke. Cerise's little pussy is so beautiful, and the inside of it is just as soft and delicate and warm and wet as the outside. She might be as dirty and hopeless a pervert as you are, but she's got the sweetest cunt you've ever had the pleasure of mating with. It only heightens your enjoyment. As do the soles of Cerise's feet pressing insistently against your backside, trying to force your cock ever deeper inside her, beckoning you to jizz directly in her womb.
Your unprotected dick is about to cum inside your sister's body and you couldn't be happier.
"Ohhhhh," she screams. "Ohhh, I feel it... I feel it, Alabaster... are you gonna--"
"Yes," you gulp.
"It's getting bigger... oh, fuck... it's getting so big... you're really gonna do it--"
Your neck muscles strain and you pound extra forcefully into her: full strokes, bottoming out completely each time, coaxing out your sperm. Cerise's orgasming pussy helps it along, milking you off as it shudders and spasms around you. You feel lightheaded and see stars, as you force your cock fully into that clamping pussy of hers and surrender yourself to the greatest orgasm you've ever had. Your entire body tingles and your balls almost hurt as they fire pulse after searing pulse of thick, hot semen into Cerise's deepest parts. Again and again your cock blasts those sticky spurts of cum against her inner walls, into her suckling womb. You hose your older sister's cunt with what feels like gallons of your fertile seed. She wails in delight at the way your throbbing dick gets off in her. It's a cum that seems to last for minutes on end, a simultaneous release better than anything you've ever felt.
As you slowly pull out, your cock, still oozing cum, adds to the messy creampie. It trickles lewdly from her glistening fuckhole. She's leaking your cum all over the sheets, and her cunt is totally full. Her breaths are ragged and she's smiling broadly, staring down at the same sight -- staring down at the way her little brother's dick milk coats her pussy inside and out. Glancing over your shoulder, you check the time: 4:21 PM.
