Nood's Filthy List of Dark Lengthy Sister Prompts

There are no puppies. I lied.

These are long. Like.... seriously... I kind of got in the zone and went off a bit. If any of these interest you, they don't have to be EXACTLY as written, ya know? If you like the concept but want to change details, I'm for it.

Also wrote a lot of these for a site that was like NO UNDERAGE CHARACTERS!!!1. I prefer teen sisters... most the time.

Siblings can be annoying. Very annoying. You've dealt with them your entire life. Traditionally, this is why it's so hard to imagine having a sexual relationship with your sibling. Ew. Gross. Them!? You just see them as this annoying person you've had to put up with. Even if you get along, you either feel you have to protect them, or you look up to them. The thought of crossing that line just feels wrong, like you're betraying some unwritten law.

What if the unwritten law is the opposite. Siblings were meant to be life partners. Or at least... always the back-up. We've all had bad relationships. Bad break-ups. You can't break up from blood. What if they were meant to always be there, no matter what. Even amidst relationships, no one really knows you like your sibling and it'd be accepted that if your partner has a brother/sister, you'd be expected to share.

Perhaps they're meant for... training... mating. Or simply an outlet for your sexual desires. To be taken, and molded how you see fit.

However you imagine it, there's nothing as immaculate as breaking the forbidden barrier with your own blood and indulging those dark and dirty thoughts we've all had but are too afraid to act upon.

A few prompts for your consideration. I am open to suggestions or modifying the prompts in ways that may appeal to you as well as I.

The Price of Notoriety: You and your brother share a place to save money on bills. Split the rent, divvy up the utilities. You got rules about having people over... basically... it's a quiet, safe space. Take any funny business elsewhere. And starting out, you both had your own jobs. Nothing special or fancy, but it paid the bills.

It began as a hobby. Just something to kill time, and admit you enjoyed the attention. From random vlogs with very light modelling thrown in... IE just showing off some things you bought. You notice more people seem to be watching your vids than your bro, friends and co-workers. Your videos are growing so much, you're able to monetize... and even make decent money. Enough to pay rent, at least. You ask your brother for suggestions on how to grow bigger. Jokingly, he tells you to whore yourself out or something. You say "Why not?" At least model more clothes, and maybe do a swimsuit/bikini special.

It overwhelms you... and end up asking your brother for help. Mostly as a photographer and editor. It feels a little strange at first... his eyes always on you while you're posing in fairly revealing bikini's... but he jokes to make you more comfortable. Soon... it seems like he's directing. The poses and bikini's become more sexual. Making alluring faces at him as he puts the camera in rather unenviable positions. It's embarrassing but also a little... arousing. You're not posing for your brother... you're posing for your followers... he just happens to be taking the pictures and telling you how to pose... bossing you around...

It came out of the blue during a shoot one day... same as always... sexy posing... low angle shots... he kept getting closer and closer. And you let him. Kept telling you to do things. And you did them. He's not even holding a camera anymore, just coming for you. Your lips briefly protested, yet your body eagerly welcomed him inside of you. No words spoken. Just heavy breathing and moaning... the sounds of passion as he took you. It was something you both needed. Just to get out of your system. Then never speak of again.

But it continued to happen. And not just between the two of you... bringing the camera with him... snapping shots as he takes you. You tell him not to post those. He says no one will know. He'll crop out/blur his face if it's in any shot. Views and cashflow skyrocket.

Before you know it... you're cosplaying different characters for your brother to fuck. The videos go up. They make loads of revenue for the both of you. No one knows it's your brother in the vids. All is good. Until.... someone slips...

During a livestream, you're chatting and modeling. He's teasing you off camera. You reveal it's the guy you've been with in the vids...but don't say who. But he keeps teasing and it comes out, "My brother can be such a dick!" ....interest and views peak. Donations flowing in. The people want to see it. No hiding. You and your brother having sex live on stream.

It's a huge success.... and continues to be for a long time... setting you both up for the foreseeable future. But at what cost? How do you deal with this now? Live with it? Do you form a relationship? Or just have sex? And how will everyone you know react? Your parents...?

Your brother jokes, "Heh... maybe Dad will want to join in, too!"

The Debt: It's no secret that your brother is a drug dealer. The most well-known one on campus... maybe even in town. Now in college, you wished to spread your own wings and create your own identity. Yet somehow... everyone knows. Is it... the name? Word of mouth? You've never had any issue with your brother or what he does. You never asked or got involved and he never tried to push anything onto you and you two got along fine.

Now it's becoming incredibly annoying. Anytime you go out or to a party... people keep coming up and asking if you have anything or what your brother has... how to get ahold of him... You keep having to explain you don't know... don't get involved in that... over and over and over. Nearly wished you never knew him... until one night...

The kegs and booze that were ordered fell through. The party was dry. It was too late to make a run and everybody was ready to go. As they all wondered what to do now... with great regret, you sigh... "Let me make a call..."

Your brother was shocked to hear you calling for that, but he was happy to help. He told you to come over where he supplied you with a felony level amount... gave you a quick lesson on how to deal and not get caught... a list of people and numbers you needed to deliver to... the prices for the various amounts... all the slang names for it all... even had a good amount of 'samples' to hand out to help gain new customers... he said he'd split all the profit with you and even gave you a baggie to keep you going all night if you wanted it.

You'd never done anything like that before... drink sometimes... smoke weed on occasion. He said if you don't want it, then sell it. You didn't think you'd want some, but as you went back to the party... the people... constantly in your face... yelling for you... asking for stuff... keeping track... who knew it was so stressful to deal drugs!? Finally, getting a place alone to catch your breath in the bathroom, you open the baggy and figure a little won't hurt. Get through tonight, and call it. Be done. With all of it....

It was all a blur.... next clear memory... waking up... not... hungover... or sick... just... confused? Where? What? So many messages on your phone... missed calls... mostly from your brother... shit, morning already? Not quite... Not just one day, the whole weekend. You did your stash... all the samples and most the ones that were already paid for... he's gonna be mad... but he's your brother... he'll be cool about it, right? And the way you feel... hopefully give you... a little more....?

He's not mad... just disappointed. Great. He's not as upset about the dope or the money so much as the damage you've done to his reputation. Made him look like a two bit dirt slinger... lost customers... and the worst was when you asked him for another fix. And he said Yes. On one condition. Until he's paid back in full (with interest, of course) you will do whatever he tells you to do. And he'll even keep you high in the process. Good deal, huh?

At least he let you get high before he raped you... mostly a blur... with some moments of clarity... watering eyes and gagging as something pumped in your throat... a surging wave of pleasure coursing through your body as a warm gush filled your loins... an uncomfortable burning... pressure and stretching behind you... horrible things cursed and said to you as your filthy rear hole gets pounded.

This is your life now. Moments of horrible clarity between blurred days of euphoria. Will your brother just make you his personal fuck toy? Maybe pimp you out to the people who didn't get their orders? Maybe take a cue from another prompt, and whore you online? Anything his drugged up, sick mind can think of...

From Loathe to Lust: For as long as you remember, you and your brother have always hated each other. And I don't mean your typical sibling rivalry. Just the thought of him either gets your blood boiling or makes you sick to your stomach. So you would think by the time you both grew up and moved out... you'd never want to see each other again... yet the two of you see each other on a near daily basis...

Not because you want to, of course... but through a horrible fate or insane coincidence.... perhaps insidious plotting? You ended up dating his best friend... and he ended up dating your best friend. Guess who his room mate is? Your boyfriend. And guess who your room mate is? His girlfriend. You can't make this shit up... (Well... I guess... actually...) Double-dates are avoided as often as possible, but him ending up at your place or yours at his... is a regular occurrence.. the heated stares and talking behind the back intensifies.

One uneventful night, you were sprawled out in your bed... or maybe your boyfriend's? Don't recall... one of *those* nights... but you suddenly hear him crawl into bed and for some reason he's quite eager... you're shockingly... yet gladly... woken up by hard, warm girth filling your womanhood completely. A started yelp turns into a satisfied moan as your hands grip the sheets tightly. From primal instinct, your body opens, raises and presents itself... welcoming him inside of you as his sudden exceptional manhood deeply massages your aching loins in the most perfect way... he's scratching every itch you have and all you can do is bury your face in your pillow as he juices your peach with every thrust.

What has suddenly gotten into him? He's good, but he's never been *this* good... it's like he can read your body, changing his pace and intensity as you crave it... pinning you down, pulling your hair and gripping the back of your neck so tightly... he's never so rough and dominating... when you peak, you orgasm so intensely that you feel may have suddenly gotten Parkinson's disease, epilepsy and a mental illness all at the same time in addition actually hoping that got you pregnant, feeling the explosive burst or warmth deep inside you... not because you want a child, but after that... he fucking deserves it...

"Holy shit..." You're finally able to utter after catching your breath and ceasing to convulse, "It's not my pussy anymore... it's all yours now, baby..." Charming words of praise.

"Good to know, sis..." The voice returns. Your heart sinks. Blood runs cold. Throat tightens. Do you vomit? Scream? Kill kill kill!?

"What the f--- how... why!? YOU...!!" Words are hard. Turns out, your brother also had a long night... meant to go back to your room mate's room... he went into the wrong room. Saw your ass sticking out of the blankets... thought he'd be giving his girlfriend a pleasant wake up. Noticing she felt better than usual... more inviting and comforting... that he fit perfectly inside her suddenly... proceeded to fuck her brains out. Only her being you... his sister... not realizing until you dedicated your pussy to him in your post-nut haze.

Angry exchange is had. Denials and accusations. Room mate/gf wakes up and peeks in... luckily you two were no longer in an awkward position... you both seem to quickly settle on the story he just walked into the wrong room and they started arguing cuz it's what they do. She buys it, and that's it... for that night...

The next time you're alone with your brother... it's time to have it out. How the hell could he have done that and not know!? Again however, rational discussions are impossible with him. More accusations and more denials. Seeing red, you threaten to bring him up on rape charges. As always... things escalate and escalate, only this time...

"Rape...?" He returns, "That wasn't rape... this, however...!!" His hand is on your throat, forcing you back and down. Cool air on your lowers signaling that you're suddenly exposed. Holding onto his forearm, he tosses one of your legs up over his shoulder and begins to dig into you so thoroughly he may scoop your ovaries out with his meaty cock head.... again leaving you like Michael J Fox with down syndrome.

This is it now... every chance you two get... whenever you're alone... all that anger pent up over the years bursts into the most intense angry hate fucking either of you could ever imagine. How will it end? Will your partners/room mates bust you? Will it blossom into an intense passion, or progress to more and more sadistic/depraved rape?

A Cult of Multiple Personality: I take care of my sister. Nothing weird, she's an adult but she has a certain condition. She's completely functional, you just never know when she's about to become someone else for awhile... such is the case of multiple personality syndrome. But the worst part is... nothing to do with her... but... I may be in a relationship... with a couple of her personalities...

Does that make me a terrib-- Yeah, ok... YEAH! IT DOES! I'm a piece of shit, okay!? But it's not like it's something I planned... it just kind of happened... And let me preface this by saying I never had a thing for my sister before. She is and always has just been my little sis. Nothing more, nothing less. Not in the onii-chan, I'm stuck sort of way, either. Never saw her that way. I'm her big brother, and I've always taken care of her. End of story.

But it's not... It started one day when her personalities began to reveal themselves. Didn't know she had a disorder until then... We were having our usual Tuesday taco hang out and binge TV shows night and she ended up falling asleep as she typically does. When she woke up about an hour later... she seemed really dazed and confused... didn't know where she was or what was going on. "Hitting the wine coolers a little too hard tonight?" I teased, "It's taco Tuesday movie night, as usual!" I explained. She nodded... looked around as if she was taking it all in for the first time... then she asked me what my name was... I told her, then she asked...

"A-are... we lovers...?" Now this is not a shocking, hol'up, record scratch type of moment you may think it is. If you know me and my sister and how we like to mess with each other. We'll play the game of taking things too far until they become uncomfortable before one of us finally gives in.

"Oh yeah... super-passionate, too... we do it all the time! Several times per day!" I joke in return. She turned a little red and got quiet... I only thought it was strange because she had no comeback for that immediately. Instead, she moved closer for a snuggle... STILL NOT WEIRD, sibling snuggles are perfectly normal! I zoned out on the show for awhile until she suddenly moved, and straddled me. "Uh... what are yo--"

Was all I got out before she held my face and leaned in for a kiss. I clammed up at first... not sure how to react... either she's really committed to this bit or... lips so soft and inviting... I returned to see if she would break. Not at all! Hello tongue in my mouth and grinding herself against my crotch. By the time she pulled away... strands of hair falling over one eye, the other gazing at me with a hint of longing as she bit her lip and placed her hands on my chest. I was not looking at my little sister anymore. This was someone else...

"Several times a day... right...?" Her breath quivered, "Lets not lose that passion..." My hands were on her hips. My cock was hard. She was already working on undoing my pants as I helped slide off her panties and she took me inside of her. My heart raced like a speed addict. I'd heard that saying about making love being different than sex... and that may be the first time I ever made love... kissing deeply the whole time until we came together... gazing into each other's eyes. After a quick clean-up, we fell asleep together snuggled up on the couch. The next day when she woke up...

"Oh man..." She pushed off me and stretch-yawned, "Slept through taco night again!" Tone and attitude were different... this was my sister again. "What's with you? Need to go rub out your morning wood or something!?" She laughed, "Just... get it away from me, dude!" She winced and waved me away.

"You don't remember...?"

"What? Boring ass show?" She rubbed her eyes, "Or damn wine coolers... sorry, man... you know I'm a lightweight..."

And that was it... she remembered nothing of it. And that's usually how it goes. After she switches over... the other personality will take over until she falls asleep... then wakes up as my little sister again. But the thing is... that's not the only personality....

That one was my lover. She's soft, tender and... well, loving. Passionate sex and cuddles. If you think that's bad... there's another that puts that one to shame... I call her the freak. You can usually tell it's her from the sudden change into revealing outfits, bikini's/swimsuits, underwear/lingerie. She's super chill, yet outgoing... if that makes sense... and she loves to fuck. Anywhere, anytime. Don't even have to ask. Even loves anal. The weirder, the more she likes it... if only my sister knew the things I've done to her... well, her body at least...

There's another I call 'The Victim'... but... lets not go into detail about her or what I do to her. Listen, I'm not proud of it! But when life gives you lemons... make lemonade... when life gives you sister with multiple personalities DTF... then fuck them whether they consent or not...

That's all I'm gonna say about that...

And they're all the same... afterwards, they usually fall asleep then my sister will wake up later. I've gotten good at making sure they're all 'cleaned up' before she returns... so she doesn't suspect... although sometimes I wonder... what if I'm not the fucked up one here, but she is? Like she's had some big brother fetish this whole time and this is just an act she came up with to satisfy her secret desires?

And... I do love my sister... not like that, but you know... the RIGHT thing to do would to tell her, but... have I gone too far? Would she forgive me? Or maybe something would develop between my sister and I? Who knows?

Fallen From Grace: Was anyone else ever blessed/cursed with having the hot older sister while growing up? Like you thought you were cool cuz so many of your friends wanted to come over to hang out, but in reality they only wanted to catch a peek at your sister. If I had a nickel for everytime I heard someone say "Oh man your sister is so hot!!!11" Bah, fucking kill me.

Not only attractive... but popular, athletic, top of the class in grades. So literally everything going for her. Me on the other hand... discovered that weed, classic rock and video games make a great combination! Needless to say who the parents were proud of and who just kind of existed along through nowhere job after nowhere job currently into adulthood.

So you'd imagine my surprise one night, when I'm about ready to get high and hear a knock on the door... which is always a surprise and send me scrambling to hide any visible substances or paraphernalia... fearing a 3-12 month vacation with my new room mate Skeeter... but as most the time is usually door dash... but in this instance...

Holy fucking shit. Haven't seen her in years... big sis. Pride of the family. Off to prestigious university then travel abroad and blah blah blah. But apparently, problems with addiction run in the family. Turns out college started off pretty great, then she started to get into the party scene... as one does in college. (Or so I've heard...). Picked up drinking... smoking some weed from time to time... then just like her younger bro, moved onto harder substances. Whereas USUALLY I'm able to contain such things to occasional use and special events... she went full blown addict.

First her grades began to drop... then her attendance. Stopped showing up for classes. Sleeping, or not sleeping late... and eventually got kicked out. Too ashamed to call Mom and Dad, lest they find out the golden child had fallen... she attempted and failed to hold job after job. Eventually ended up bouncing from shitty boyfriend to shitty boyfriend until she got tired of the abuse and wound up at my place, pleading for a place to stay until she could clean herself up and get back on her feet. Somehow... if there is a higher power... it's an asshole... as she's still smoking hot after all of that...

I didn't particularly want my sister living with me... knowing it'd just bring trouble... plus I had a pretty cramped place as it was for just one person... two would much worse. She promised she wouldn't cause any trouble and no one would come looking for her. In fact, no one would even know she was here. Aaaand as she was making all these empty promises... she lit up as she noticed the goodies I had been waiting all week to ingest and enjoy some quality alone time with.

She practically BEGGED me for just one hit. That's all. Just one and done. Sure, yeah. I told her to grab some water from the fridge and I'd load her up something special. Awkward hug with a "You're the best!" empty sentiment while I added a little special ingredient to hers. She didn't even question it, immediately took a hit as I took from a separate one.

"So here's the deal..." I started, "As long as you're going to be staying here... I have full rights to your body... to fuck you. Whenever I want to. However I want to. And you cannot refuse or resist me." I took a hit of my own, blew it at her, "...or I mean you can... I'd prefer it if you did... it's more fun for me that way..."

Her eyes were wide... from the drugs and my ultimatum. "What the fuck is wrong wi--" She appeared as if she were to stand up and storm out, but her limbs failed her. She started sinking back into the couch, failing at trying to pull herself up, "What did... did you do...!?"

"Special ingredient!" I grin, "Juuuuuuust a bit of GHB to your crank... it won't knock you out... you'll be totally awake and aware... just... unable to you know... struggle and stuff..." I helped lean her back, then rolled her over the arm of the couch.

"You're sick! You can't do this! I'll tell..." She began.

"Who? Mom and Dad?" I returned, "That you became a junkie and got kicked out of college? They still send you money each month? Spent it on shit, I assume?" Slowly pulling her pants down, "Look... say anything... I'll inform our parents... the university council... hell, I bet some of your old boyfriends are looking for you and would love to know where you are..."

"Don't! Please!"

"And the cops? Look..." I admire her ass... still plump and round as ever, "You're not the golden child anymore... you're a drifter... I have a steady job... a home, a car... I pay my bills..." I peel the thong off and get on my knees behind her, unbuttoning my pants, "They're not my drugs, officer... she must have brought them into my house! She's my sister, I trusted her! My job drug tests, I couldn't even if I wanted to....!"

I'm sure it's been heavily used by now, but the closure and satisfaction of sinking inside of the most sought after pussy in my life... belonging to my sister... was incredible. She whimpered as I fucked her. Not from pain, likely, but from even her own brother betraying her like this. After I came inside of her, I could have died right there. What could get better than this?

"Don't..." She protest too late, "Can't afford... BC anymore... I might get..."

"Your problem, not mine..." I told, pulling out. "Blame it on one of your supplier boyfriends."

As I pondered if she'd recover... get better and I'd lose this wonderful free ass... or maybe something would blossom between us? Or perhaps I would just enjoy getting her pregnant and watching her have my bastard child just for fun...
