Introduction:

Rob hacks into his sister’s Twitter account and sends fake tweets, that turn out to come true.

Chapter 7

Rob yawned, and rolled over to the increasingly-familiar sight of his older sister’s tattoo-covered boobs, and pierced nipples. He decided to wake her up by sliding his thick, veiny cock inside of her, while pulling on her piercings and—just to make sure she was awake—slapping her on the ass. As soon as he inserted the tip of his cock, however, she moaned loudly, and opened her eyes.

“Oh, Rob,” she moaned, and wrapped her legs around him, pulling him in as far as he could go. “Stretch me out!”

After just a few pumps, Amber was screaming in pleasure. Rob decided to join her in orgasm—he wasn’t used to having quite this much control over his load, but as soon as the thought crossed his mind, he was able to really let loose, filling his sister’s wet cunt with wave after wave of his semen.

“Mmmm,” he said, lay back, his sister joining him.

It wasn’t until a few minutes later that he remembered Annie. Forcing himself out of bed, he wandered downstairs, to find her sitting at breakfast with their father.

“Hey Dad,” he said with a yawn. Both he and his father were completely naked, but for some reason it neither of them seemed bothered.

“Did you get off inside your sister already?” his father asked, as casually as one would enquire about the weather. Rob just answered with a grin, accepted the toast his father offered him, and sat down to eat while Annie slithered under the table to pleasure him.

A few minutes later, his mother entered, wearing her now-standard slutty make-up, and seeing what Annie was up to, joined her. The pair of tongues going up and down his cock would normally have set him off after ten minutes, but the unusual control he’d felt earlier in the day was still present, and he easily held off until he’d finished another two slices of toast (served to him, once more, by his father) and leisurely enjoyed a cup of coffee as well.

Neither his sister nor his mother showed any signs of growing weary, but remembering what today was, Rob decided not to hold back any longer, and came over both of their faces.

“Enjoy!” he said, skipping upstairs to where he knew Amber would be waiting for him.

“Hold it right there!” Rob’s father said to the cum-drenched pair, pulling out a camera. “This one’s going on the home page!”

Upstairs, Amber was laying on the bed, seeing if she could fit both fists into her stretched-out pussy. She couldn’t, not yet, but even as Rob watched, he saw that she was making progress.

“Save that one, sis…” he said, after a few minutes of watching her. “You know what today is!”

* * *

Downstairs, Annie enjoyed the feeling of her father slowly entering her wet, sloppy cunt for the first time. But certainly not the last, she thought with a cheeky grin. That Hacker program really works…I’ll have to jump on again next time I’m in Rob’s room.

She lay back as her father grunted, pounding in and out of her pussy. Across the kitchen, her mother was sitting on the kitchen bench, trying to see if she could get a rolling pin up her tight ass.

“Come on Mom, you can do it,” she said, before her eyes rolled to the back of her head as her father’s cock hit a new depth.

“Thanks, sweetie,” she replied with a grin, coating the pin with another layer of lube and trying again.

Annie shuddered in a small orgasm, but didn’t even particularly care—just the knowledge that she was the kind of dirty slut who let her Daddy fuck her bareback was enough to make her happy. Cumming was just the cream on the cake.

Less than a minute later, her father filled her with cream, the pair of them panting with exertion as he came inside his daughter for the first time. She’d started goading him just a few seconds before he came, warning him that she wasn’t on the pill.

“Do you want to knock me up?” she asked, her bright, innocent eyes shining up at him. “Do you want to put a bun in your daughter’s oven?”

That seemed to be what pushed him over the edge, and she mentally filed the information away, before getting up, admiring her mother’s efforts, and heading upstairs to join her siblings.

“Rob!” she admonished, walking in on Rob fucking Amber’s face so hard it looked like there was serious risk of her losing an eye. “Did you forget what today is?”

“No,” Rob groaned. “Of course not, Annie. I was just…finishing.”

He gave one more big, final thrust, splattering the back of Amber’s throat with cum. He pulled out, and gave Annie a hug.

“Now, let’s go get that tattoo!”

* * *

It wasn’t until they were in the car on the way to the tattoo parlour that Rob realized something was wrong. He’d never updated the twitter about a tattoo with his sister, wanting to wait until he got the photos that Amber had taken, and finished the Photoshop. And he’d certainly never discussed the idea with Annie…so how did she know?

His eyes widened as he realized what must have happened, and as soon as they pulled into the parking lot, he opened up his phone and checked Twitter.

Someone had been updating Amber’s account.

October 21st: my little sister is so hot. she’s getting her first tattoo today—everyone is excited

October 21st: she’s come up with a system—after her 1st tattoo, she’s going to fuck 1 guy. after her 2nd, 2…such a great idea

October 21st: and now that we’re all involved, everyone has agreed—our whole family can be naked and fuck in every room. every1 is so chill abt it

October 21st: i have the best fam eva!

October 21st: dads gonna start up a family website 2 pay the bills so all we have to do is tape the fucking and we’ll neva have to wrry about money again!

October 21st: and rob is da best lova eva. he can control his orgasms and make girls cum just by having them touch his dick. every1 thinks hes the sexiest

Rob sat back with a puzzled look on his face.

“Come on girls, get dressed,” he said without even looking at the back seat of the car. As soon as his sisters had gotten in, they’d stripped off and started making out. He didn’t know who was updating the Twitter, but whoever it was, they seemed to think well of him.

A pair of girls passed the car, and stopped for a second as soon as they saw Rob. He winked at them, and their giggle was only cut short when they noticed the two girls getting dressed in the back.

They stormed off, but Rob still mentally thanked the mystery updater. He would never have thought of making himself irresistible to strangers—in the unlikely event that he tired of his sisters, it meant that he could go out and find someone else to keep him company without effort…

On the way home, Rob had to keep telling Amber not to touch the plastic on Annie’s arm.

“She just got it,” he snapped. “Here, come and hold my penis.”

With a thought, he was able to make Amber cum. It distracted her for long enough to get them home, where the whole family gathered around to admire Annie’s new ink (her father with camera in hand.)

It was a simple pink rose. Hidden in the petals was a drawing of Annie’s own little pink cunt, and underneath it simply read “open for business.”

“So who’s going to be the lucky man?” her father asked, and Annie rolled her eyes.

“Isn’t it obvious? I want Rob’s magic cock to really start work on stretching out my asshole.”

“Do you mind if I film it, sweetie?”

“Of course not, Daddy.”


Chapter 8

After Annie’s second tattoo a few days later (a ring of boobs around her belly-button) Annie’s mother had to hold the camera, so that the two men taking her could be her brother and father. They bellowed as they came, Rob timing his orgasm to match his father’s, and when they were done, sat down, panting next to her.

“Who are you going to get in for number 3?” her father eventually asked, and Annie smiled in response.

“I’ve got a few ideas, Dad…”

As their father ran off to edit the recording (he’d fallen in love with the “home video” look, though was still planning on getting a crew in for special occasions) and update the website, Amber followed after him. (“He works faster when he’s being blown!”)

Annie jumped back onto Rob’s cock, and slowly slid her body up and down. She wasn’t horny, but until their extra-large toys arrived, there was no other way that she could think of stretching herself out. Her mother had a monopoly on household items - she was currently walking around with a bottle of coke sticking out of her ass, and what looked like the family’s flashlight shoved into her pussy.

There was just something about being stretched that really appealed to her - she suspected that it had something to do with Amber’s twitter account, but since Rob had caught her sneaking on (to try to give herself the world’s most sensitive nipples) he’d forbidden her from going near it again, and just to be safe, typed an entry to that effect.

If they hadn’t determined the first time a special occasion worthy of getting the film crew in, she would have suggested that Rob fuck his mother, but for now, she was happy to just sit and watch the woman desperately try to stretch out her holes, while she bounced up and down on her brother’s cock. Small orgasms rippled through her body, and when she shut her eyes, she could see herself in a few months time - stretched, loose, covered in tatts, and being gangbanged by ten, twelve, fifteen men…

* * *

Annie woke up with a smile. She loved her new life - she knew that at least part of that love was artificial, but no part of her cared. Before her brother’s meddling, she’d only ever cum a few times a week, and even then only by her own hand. Now, it was rare for her to go more than an hour without an orgasm or five - and most of them were accompanied by the delicious feeling of being stretched out by her brother. Her life had turned into a constant sexual haze, constantly pleasuring men and being pleasured…

She’d never been so happy.

Slipping out of bed, careful not to wake her mother, father or brother, Annie looked at her naked body in the mirror.

Her tits were plump and obviously fake - she’d begged to get implants for her birthday, just like her sister. Finally, after his fifth orgasm of the night, her father had agreed. She’d grinned up at him, his cum spilling out of her mouth and landing on the floor.

“See, Daddy,” she’d said seductively, “once I have the operation, I won’t make such a mess on the carpet…”

The mental image of his youngest daughter dribbling cum onto large implants was enough to get her father hard again, and Annie’s eyes had lit up at the sight of her father’s huge cock thickening once more…

Turning around in front of the mirror, Annie couldn’t help but be proud of her progress. Her asshole gaped invitingly, and she reached around, just to watch her entire hand fit into her rear cavity.

When she withdrew her hand, it was slimy, and Annie smiled. She was so frequently pumped full of cum that she was constantly lubricated, ready for whatever cock wanted to take her next.

Her tattoos had been slowly growing in number - she was up to number eight now, which meant that next time she got inked, she’d have to find nine men that she could service. Her eighth tattoo was a fierce dragon, with a ferocious look on its face, and a huge, fiery, threatening cock. It was aiming it toward a young fairy that looked like a combination of Annie and her equally-slutter older sister, dressed like Tinkerbell, bent over to expose a huge, red, ass. The fairy was reaching behind herself, opening her hole up for the dragon’s huge member, a look of fear and lust on her face…

It had been expensive, but Annie and her sister had received a half-price deal in exchange for going around to the tattoo artist’s house for the weekend and sericing his every need…

A noise behind her made her start, but it was just her brother, slowly sliding into their mother’s sleeping form.

Annie would never forget the day that Rob had first taken his mother - it had been a huge occasion, and when Annie had seen Rob typing at his computer directly beforehand, she’d known that he had something up his sleeve…

September 20th: gawd my mother can squirt

September 20th whenever she cums its like a flood. delicious tho! ;) my sis and I can never resist it…

When Rob’s cock had come out, his mother had stared at it, entranced, practically drooling. She’d tasted it before, but she’d yet to be fucked by his beautifully huge member…and it was becoming rare to enter any room of the house without seeing Rob screwing someone, whether it was one of his sisters, the neighbour, or even a random woman he’d picked up on the street. Ever since Annie had made him irresistible to women, he’d been taking full advantage of it…and them.

But knowing that at last she’d be fucked by her own son, the boy that she’d given birth to…Rob’s mother had seen how much pleasure he brought other women, and she was practically trembling with anticipation.

Annie and Amber had sat to the side as Rob’s father had directed the scene, running the crew approximately through what was going to happen, where to focus the cameras when, and making sure that Rob and his mother knew their roles.

They’d nodded along, but Rob had glanced at Annie, and she suspected that they’d both known that nothing was going to go as planned…

As soon as Rob had slid inside his mother’s mouth, her orgasms had started, and - just as Rob’s tweets had instructed - juices gushed out of her so quickly that Annie’s last rational thought was that her mother ran a serious risk of being dehydrated.

The fluids started flying, however, and Annie and Amber ran forward in delight, desperately keen to taste the delicious liquid, touch it, bathe in it…

Rob’s father had improvised, as necessary, and the home video of Rob taking his mother for the first time had earned a subtitle - “Sister Sluts Love Mother’s Squirts”.

Watching her mother and Rob now, Annie took the opportunity to play with herself. She knew that she didn’t have long to make herself cum - as soon as her mother did, her mind would go blank, and all she’d be able to think about would be getting her mother’s sweet pussy juice in her mouth, gulping it down as fast as it could be produced.

With a grin, her brother watched her desperately play with herself. He had complete control, she knew - with a thought, she could make their mother cum, and Annie getting her orgasm before then relied entirely on Rob’s goodwill.

As Annie forced an entire fist into her own cunt, her eyes widened. She watched Rob pull out his cell-phone, where she knew he’d recently installed the portable version of Master Hacker. She wanted to cum, but more urgently than that…she had to know what he was writing.

February 3rd: Luv my sis’ pussy. As much as she stretches it, its tight again the next day. Wassup wit dat??

February 3rd: Unlike my cunt wich gapes more every day - LOL

Rob watched as his sister glared, while her pussy lips began to tighten. She’d spent so long, used so many large toys…and he’d undone all of her hard work in less than a minute. He smiled, knowing that his latest updates would drive Annie crazy - Annie had become obsessed with being stretched out, and his wording had ensured that no matter how hard she tried, she wouldn’t be able to loosen herself as much as Amber.

Before she could say anything, he mentally willed his mother to cum, and watched as Annie’s eyes glazed over and she ran forward, desperate to taste the liquid gushing from his mother’s cunt.

The abrupt arrival of another body on the bed woke their father up, and he scowled at the sight.

“Why didn’t anyone tell me you were starting already? I would have turned the camera on…”

* * *

Meanwhile, in the room next door, Amber was awake. She’d been awake for almost 36 hours straight now - her brother had set her a challenge. She was to watch every one of the family’s DVD releases in a row, and come up with some ideas for more. Beside her was a notepad with dozens of ideas scrawled upon it, and on the other side was an industrial-sized tin of lube, the largest sex toys that the family could find, and a pile of bottled water, to prevent dehydration.

There had been more to Rob’s challenge than had met the eye.

January 29th: god i luv my fam’s porn. i can never get through a whole one without having to get myself off…

As the sixtieth consecutive porno started (“Fucked and Fisted by Father”), Amber’s glassy eyes stared at the screen, and her hands automatically reached for two of the largest sex-toys: a large black dildo, and a toy that looked like a man’s fist. Since the twenty-four hour mark, she’d been exactly duplicating the action on-screen, and cumming at the same time as the women in the film (often herself) did. It saved her brain from having to think.

The large pile of watched DVDs included “DP My Mom and Me”, in which Annie and her mother had simultaneously been double penetrated (Amber had used two thick vibrating dildos for that one), “Size-queen Sis” (a video of Amber taking the “American Challenge”, a feat that she’d replicated while watching the video) and “Sis’ Gangbang Birthday” - it had only been Annie’s birthday, but for the sake of the film, Amber had joined in, and managed to take two cocks in her ass at once for the first time.

There were only a handful to go, unless her father had managed to release some more while she’d been watching. Through the entire twenty-four hours, a webcam in the corner had been live-streaming Amber’s efforts, and every now and again a family member had wandered in with suggestions from the chat.

“Mike from Michigan wants you to use a ballgag for the next few,” her father had suggested, tying it on before she’d had a chance to object.

“Some guy named Harold wants to see you do that thing with your feet behind your back,” Annie had piped in at one point.

“A chick called Geraldine thinks you should wear nipple clamps while you watch Daddy Gapes Me Best, because you were in the video,” her mother had added, a few videos later.

When Rob had come in, he hadn’t made any suggestions, just slowly fucked her ass while “Tattooed Anal Sister Slut” played in the background. When he’d cum, he’d pulled out without a word, and left to see what his other sister was up to.

Amber looked at the small pile of DVDs left to go. Every part of her ached with exhaustion, her mind was fried, and she knew that cumming through the last few DVDs would be a struggle…but she felt a strange feeling of pride.

She turned and winked at the webcam, before turning back to the screen, and slowly sliding the fist into her loose ass. She shuddered with pleasure at the feelings coursing through her body…she loved being stretched, it gave her more pleasure than anything she’d ever imagined. And with her well-hung brother and father regularly taking her, not to mention her sister’s penchant for huge toys…well, she was constantly presented with opportunities to feel her gaping pussy expand, and hang loosely.

Amber loved her new life.
