	Chapter 1

“Mom!” Caitlin said, “he’s fucking doing it again.”

At the sound, Brad’s mother stormed up the stairs and into her son’s room. He was hurriedly trying to hide the evidence, but as he stuffed his sister’s panties underneath his pillow, his mother grabbed them out of his hand.

“Christ, Bradley,” she said, too exhausted to even be angry, “we talked about this.”

“Sorry Mom,” Bradley said, hanging his head. Not from remorse, however - he’d worked out that if he looked down while his mother was talking to him, he had a clear view down his mother’s top. Her huge tits were so close, so close that he could reach out and grab them ... but he held back, figuring he was in enough trouble for the day.

Maybe tomorrow he’d find some excuse to “brush against them”, get a proper feel of the tits he’d been eyeing off for so long.

Fifteen minutes of lecturing later, his mother was gone. Making sure to close the door the whole way this time, he reached under his mattress, and pulled out the bra he’d pilfered from his mother’s laundry basket the night before.

He was going to coat it with his cum, let it dry, and put it back in her clean pile. The image of her walking around all day with his semen pressed up against her skin was enough to get him off within just a few minutes ... Once he was done, he considered jerking off again, but the need had passed. He briefly considered sending his sister a dick pic - he’d sent her one a few weeks ago, and the knowledge that she’d seen his cock (and her angry reaction) had been so good, it had been worth losing his rights to borrow the family car.

Bradley was a pervert. It had reached the point where his family had stopped being grossed out by his antics, and just resignedly accepted it as a part of having a son. To make matters worse, his sister Caitlin was a golden child. She was head cheerleader, popular with everyone: her peers, boys, even managing to avoid the typical high-school dramas and getting along with the rest of the squad.

Where Bradley was shunned by the entire school as a known sleaze-bag, she was the beloved perfect model of what a teenager should be.

She was an ideal specimen of attractiveness as well. Tall, blonde, slim and muscular - her clean lines were only broken up by the chest she’d inherited from her mother, but she even managed to own that, dressing to emphasize her huge breasts. Bradley had a habit of “accidentally” walking in on her in the shower. Once she’d even decided to experiment with ignoring him, turning her back and letting him look at her perfect ass - she’d almost thrown up when she turned back around a few minutes later and he was gone ... leaving strings of semen on the shower door.

Bradley hadn’t been punished for that incident - he suspected she’d either been so grossed out that she couldn’t even bring herself to tell their parents, or that she’d been worried her actions would be seen as encouraging him.

Either way, she’d bought a lock for the bathroom door after that, and he’d never been able to repeat the experience.

Instead of jerking off once more, Bradley decided to keep translating the book he’d found in the attic. When he wasn’t being a world-class pervert, Bradley was a hobbyist linguist - he’d originally taken a language class because he thought the teacher was hot, but to his surprise he’d really gotten into it.

His family were happy he’d found a hobby, and happily paid for the various textbooks and website subscriptions that encouraged him to do something - **anything** \- aside from torment his sister.

It didn’t help his popularity at school, of course - even before he’d earned himself a permanent place at the bottom of the social ladder for his attitude and actions towards his women, he’d been heading there with his geeky pursuits and total lack of social skills.

Everything he did was a disappointment to his parents - they’d wanted a son who was popular, handsome, and good at sports. What they’d gotten, instead, was Bradley.

He had long since resigned himself to his place in life, and now just enjoyed the freedom it gave him. When no one has any expectations of you, you can do anything, and so he would spend his evenings stealing his family members’ underwear, crudely propositioning his sister, and - when the mood struck - translating ancient tomes.

Currently, he was on a page that had two figures in the middle, one standing imposingly above the other. A single word was written around the page - the same word, again and again.

“Let’s see,” he said, furrowing his brow. “This font looks like prototypical Greek, but it’s like someone who didn’t speak the language trying to translate it into ... what is that, Latin?”

He consulted one of the many foreign dictionaries he had on his shelf, hidden behind a stack of porno magazines.

“Change? Is that what it’s ... oh wait, no: switch! That’s the ticket. Switch. Switch. Switch.”

As he read the word over and over, a strange tingling sensation went up his arm, and he was suddenly overcome by an intense drowsiness.

With a yawn, he closed the book and switched off the light.

**Must have overdone it today** , he thought to himself, laying down and falling asleep the moment his head touched the pillow. Had he stayed awake for just a minute or two longer, he would have seen a strange glow come from the book, a glow which quickly started filling the room.

* * *

The next morning, Bradley woke up to a strange sight.

His sister was in front of him, an odd leer on her face. He sat up with a start - something was wrong. She never came into his room.

**Never**.

“Hey Caitlin...” he said cautiously. “What’s up?”

“Just watching you sleep,” she said. “You know you get a hard-on in the morning?”

“Uh, yeah,” he replied, too weirded out to register the purr in her voice. “It’s called morning wood.”

“I like it,” she said, and moved one hand down between her legs. “It gets me wet.”

**What the fuck?** he thought to himself, but before he could respond, he could hear his mother walking down the hall.

Caitlin immediately moved her hand out from between her legs, but made no efforts to leave - she continued standing there, an odd look on her face.

“Caitlin!” their mother said, “oh God, you’re not in Bradley’s room again are you? You know how creepy that is, honey. Just let your brother wake up in peace, okay?”

“Sure Mom,” Brad’s sister said with a roll of her eyes. Bradley just continued to stare at her, confused, as she walked out, stopping at the doorway to glance at his morning hard-on once more.

**That was weird...** he thought to himself, but after running through the morning’s events for a few minutes, decided it must have been the remnant of a dream. His sister coming into his room and talking about a boner? That was exactly the kind of scenario that showed up regularly in his night-time fantasies.

Dismissing the thought, he hid in the hallway until he saw his mother leave her room, and then sneaked in to switch out one of her clean bras with the one he’d plastered the previous night.

The rest of the day passed without incident. Bradley spent half the day sitting in the front of the class (when he had a hot teacher he could ogle) and the other half sitting at the back, drawing tits in his schoolbooks and fantasizing about the girls in the seats next to him.

To his surprise, when they caught him checking them out, they didn’t roll their eyes or call on the teacher like they normally would. They just ignored him, continuing with their work as if they hadn’t noticed anything at all. One of them even smiled back at him.

 **Must be my lucky day,** Bradley thought, taking the opportunity to be even more obvious about trying to looking down their tops and up their skirts.

Finally, the school day was ended. When Bradley returned home, he was surprised to find his sister walking out of his room, a smug look on her face.

Typically his sister didn’t come near him unless she was absolutely forced to, and over the last few years, their parents had forced them to spend less and less time together.

**What is she up to?** Bradley mused to himself. He knew that for a while she’d gotten it into her head that she could “fix” him, that his behavior was something that could be changed through positive reinforcement or whatever. She’d sat down to ask what he wanted, eventually being forced to walk out when he’d gone into intricate detail about her wet folds sliding down his cock, until he pumped so much cum into her that she was like a big, wet, fleshy balloon.

She hadn’t told their parents about that conversation either.

In response to the puzzled look on his face, Caitlin pushed her shoulders back haughtily. He was so distracted by the sudden flaunting of her tits that he completely forgot to make a wise-crack about her being in his room, instead just enjoying the view as she walked down the hallway in a short skirt that showed off her legs.

Inside his room, he considered jerking off again, imagining lifting up the skirt and copping a feel of her ass, or lubing up and taking it as roughly as she deserved - but instead he found himself oddly drawn to the book he’d been translating the day before.

He turned the page, and was surprised to find the same word surrounding another image - this one seemed even more sexual to him, but he’d learned to tune that out. **Everything** seemed sexual to him.

“Switch. Switch. Switch.” he muttered, imagining the girl kneeling in front of the silhouetted man was his sister.

Again, a wave of fatigue hit him, but he fought through it - it was barely 4pm, going to sleep so early was a ridiculous idea. He pulled out his dictionary again - there were more words at the bottom of the page. A phrase, repeated over and over, just as “switch” had been. He ran his finger down the pages of his Greco-Latin dictionary, trying to work out what the next few words could mean.

After almost an hour, he was forced to give up. Working out “switch” had clearly been a blessing - either whoever had written the book had no grasp of the languages he was writing (or translating from) or he just wasn’t skilled enough to translate it. He decided to go and torment his sister, maybe get himself riled up enough to shake off the wave of tiredness that hadn’t left him since he’d gotten home, and then return to his room and jerk off.

His sister’s door was closed, but Bradley had long stopped letting that slow him down. He opened it up and strode in unannounced, in the hope he’d find his sister in some kind of compromising position.

No luck. She was on her computer, looking at ... He did a double-take. Was that **porn**? Or had music videos just gotten way more extreme since he’d been on YouTube?

“Hey Bradley,” she sneered, distracting him from the contents of her computer screen.

“Uh, hi,” he replied, slightly thrown.

“What can I do for you?”

She sat up, and spread her legs. Instinctively he looked between them, and was surprised to find that she did nothing to stop him. He could see her white cotton panties, and it was clear from the lack of hairs poking out the sides that she kept herself shaved, or at least neatly trimmed. That had changed since she’d started locking the shower door.

He stood there, open-mouthed, as his sister did nothing to stop him from staring at her barely-covered pussy. She just continued to leer at him, and as the minutes ticked by, a wet spot appeared in the centre of the white cloth.

**What the fuck is going on?** he asked himself, not wanting to voice his confusion, or in fact do ****anything** **that would stop the show.** Is she trying a new system? Is she trying to tame me?** **... is the slut into me?** Something had happened to Brad’s sister, and he liked it.

Finally, after what felt like hours, Caitlin snapped her legs shut.

“Show’s over,” she sneered. “Unless, of course, you want to join me in the shower.”

A smile spread over Bradley’s face as he finally clued into what was happening. She had clearly decided to get him once and for all - she probably had a hidden camera in the bathroom, and if he fell for her bait and followed her, she’d have video evidence of his perversions and within a day or two, the footage would be shown to their parents.

He wasn’t sure what the consequences would be, but he wasn’t interested in finding out.

“Nice try,” he said calmly, and when Caitlin stood up to leave, resisted the temptation to react as she pressed up against him. Who knew where she had a camera hidden - no, he was better off ignoring his sister’s obvious ploy, at least until he’d worked out her plan.

She left the room, and he could soon hear the sound of the shower running. He took the opportunity to try to see if there was a camera hidden somewhere in her room - he didn’t immediately find anything, and instead pilfered a few pairs of her panties; Brad was so rarely left alone in Caitlin’s room, he decided to take full advantage of the situation.

Before long, he was making his way back into his room and rubbing one out, imagining his sister in the next room, standing naked under the water, picturing himself standing above her and cumming onto her tits.

He didn’t bother closing the door - his family had long since gotten used to the fact that Brad would masturbate, unashamed, at all hours, and only went up to his end of the hallway when it was absolutely necessary.

Moaning his sister’s name, he soon came all over a set of her cotton underwear. He considered returning them back to the drawer, but at the sound of the shower turning off, decided not to risk it. He didn’t know what his sister’s game was yet, and so he decided to take it easy until he’d worked it out.

The book caught the corner of his eye, and he turned to it, suddenly inspired. Stuffing his sister’s cum-soaked panties into a drawer, he stood up, pulled out a pen, and started writing out the characters from the next sentence. Bradley was so intrigued by his little hobby that he didn’t even notice the slight stickiness of the pen in his hand.

He’d been assuming that the writer had continued writing in the same language, but it was clear that for whatever reason, they’d switched. This looked mesoamerican - Mayan? Scribbling down the letters from the next few words, assuming they were written in the Mayan text, it quickly became clear what the author was trying to say.

“Switch. Switch. Switch.” Brad said, putting the whole thing together. “Low to high. High to low. Low to high, high to low.”

Again, a wave of fatigue hit him, faster than before. He was so overwhelmed by it that he physically staggered back, collapsing onto the bed and falling asleep before he could even pull his pants up.

Just seconds after his eyes closed, the book began to glow once more, this time filling not just his room, but the entire house.


	Chapter 2

“Morning,” Caitlin said, and Brad opened his eyes to find her staring down at him, a smug look on her face. “Looks like someone had a good night.”

Glancing down, Brad could see that he was still in the same clothes he’d fallen asleep in, the underwear he’d jerked off in and nothing else.

Except ... were they? He was intimately familiar with his sister and mother’s underwear collection, but paid far less attention to his own. He didn’t even recognize his own underpants. They felt different too - tighter, a bette fit.

“Oh god,” he said groggily, still too hazy to even question his sister’s presence in his room. “I don’t even remember going to sleep last night.”

With a glance over at his desk, Caitlin nodded towards the pen he’d been making notes with.

“Found the gift I left you?”

“What?”

“Your pen. I sweetened it for you.”

Brad wrinkled his nose in confusion. If his sister’s plan was just to confuse him, it was certainly working. Her whole attitude had changed ... and, now that he looked closer, so had her choice of clothing.

Caitlin normally slept in a nightie - once upon a time, her choices had been more revealing, but as he’d slowly given up on masking his lustful gaze, she’d responded by wearing clothes that covered up more and more of her flesh.

Nothing as much as this, however. She was dressed in slacks and a sweatshirt, an outfit he’d never, ever seen her in. It exposed less skin than anything he ever remembered seeing her wear, and - even more strangely - it looked like it was covered in grease and sweat-stains.

No. He must still be dreaming.

“Take off your top,” he said. If he was dreaming, she’d do it, and if he wasn’t ... well, what was the worst that could happen?

“Sure,” she said in surprise, then paused to collect herself. “Soon as you show me what you’re packing under those briefs.”

Bradley hesitated, and memories of their encounter yesterday started coming back to him. She’d been trying to tempt him into embarrassing himself then, as well, but this ... this felt different.

He couldn’t see a camera on her person anywhere, and while she could have hidden one in his room before coming in, it seemed risky, and he wasn’t sure what the payoff would be for her. What was she going to do, put pictures of his dick online? If that was her end-game, she could just do that next time he texted her a few shots.

For the next few moments, there was a silence between the two siblings as Bradley weighed up his options, and considered the risks. Finally, he nodded.

His sister’s reaction didn’t help alleviate his confusion at all - her eyes lit up, before being clouded by suspicion, and she tilted her head to the side.

“Really?” she said, and when he just nodded again, scoffed. “You slut.”

Brad had never been called a slut before, but if it was going to get his sister’s top off, he was more than happy to put up with her attempts at verbal abuse. Slowly he slid his briefs down. His dick had been hard already from the vague-but-erotic dreams he’d experienced the night before, but knowing that his sister was looking at it - **wanted** to look at it - had caused an erection as hard as steel.

He sat there, savoring the moment as Caitlin looked adoringly at his erection. He didn’t have a porn-star sized cock, but he’d always been pretty happy with it, and his sister’s reaction showed that she wasn’t disappointed.

“Your turn,” he said, and to his shock, Caitlin grinned, and immediately took off her top in response.

Under the baggy sweatshirt (which, he realized as she removed it, was probably her ex-boyfriend’s) she wasn’t wearing a bra, and Brad’s jaw dropped as his sister’s hefty tits came into view.

Unlike the times he’d peeked on her in the shower, this time they weren’t hidden behind glass and fog. Her smile widened at his expression, and just as she had the previous night, she pulled her shoulders back, pushing her boobs forward and arching her back.

Brad’s hands were itching to reach out and grab them, pull at her thick nipples and slap them, but he held back. For reasons he didn’t understand, his sister had just stripped in front of him, and he wasn’t going to do anything that risked this incredible sight being taken away.

“You like what you see?” Caitlin said mockingly, and Brad found himself unwillingly nodding, unable to take his eyes off the naked pair of tits in front of him. “You’re a fucking slut, aren’t you?”

He was about to say something in response (he wasn’t sure what, but **something** ) when his mother stormed in.

Brad’s suspicion that it was a dream increased when her response to her two children exposing themselves to each other wasn’t anger or shock, but simple resignation.

Directed at Caitlin.

“Jesus Christ, girl,” she said with a frustrated sigh. “You have got to stop this. Leave your brother alone!”

Bradley almost opened his mouth to defend her, but immediately worked out what a poor plan that was. He had no idea why his mother had assumed this was Caitlin’s fault, but it was very much in his best interests to let her keep on assuming.

Instead of defending herself, his sister just rolled her eyes in response, and slovenly made her way out of the room, not even bothering to put her shirt back on.

As Brad watched his sister’s incredible tits leave, his mother turned to him, a look of concern in her eyes.

“Are you okay, sweetie?”

“Uh...”

Before he could formulate a thought, she continued.

“I’m sure she’ll grow out of it. She has to.”

He nodded in response, and his mother shook her head.

“Anyway - would you like a lift to school today? I’m heading off in a few minutes. Breakfast is on the table, so quickly get dressed and I’ll drop you off.”

Now totally convinced that this was a dream Bradley reached out and cupped his mother’s breasts instead of responding.

“Bradley!” she said, sounding more shocked than annoyed. “Don’t tell me your sister is rubbing off on you - stop fooling around and get dressed.”

Only as his mother shook her head and leave did Bradley remember that his erection was still out in the open. After a long pause, he reached out and pinched his arm.

It hurt.

**Okay,** he thought. **Not a dream. So what the fuck is happening?**

* * *

When he arrived downstairs for breakfast, Bradley was better-dressed than he’d ever been in his life. He’d opened his closet and been met with a collection of clothes he’d never seen before in his life - crisply-pressed polo shirts, jeans, even a suit jacket or two.

They all fit ... and they looked **good**.

Bradley had never been bothered with fashion, but as soon as he’d put together an outfit for the day out of the mysterious clothes that had taken the place of his usual wardrobe, he’d recognized how much they suited him. A glance in the mirror had shown him that even his usual neckbeard was gone, replaced with overnight stubble which - again - suited him to a T.

As he ate the bacon and eggs his mother put on his plate, he mused on what could possibly be going on. It couldn’t be a trap - there was no way that Caitlin could convince his family to go along with it ... and besides, why would she shave him and buy him several hundreds of dollars worth of new clothes?

The taste of his mother’s cooking proved to him that it wasn’t a dream, and he didn’t know much about hallucinations or insanity, but he was fairly sure that everything wasn’t meant to be this ... crisp.

But what was left?

He continued to think about it as his mother drove him to school, chatting to him in the front seat. Caitlin was in his usual spot in the back, and when he looked back, he was unsurprised to find she had one hand down her pants, leering at him as she played with himself.

It made him surprisingly uncomfortable, and he turned his attention back to the front where his mother was asking him about his plans for the week.

“Nothing much,” he said, and she laughed in response.

“Sure thing, Brad. Just let me know if you’re going to be out before midnight, okay?”

“Uh, okay.”

Brad had no idea what his mother was talking about, but before he could enquire further, the car arrived at school and his sister and he got out.

That day was unlike any other day the teenaged boy had ever experienced. Instead of the mocking glances and sullen stares he received on a typical school day, a pair of cheerleaders were there to greet him outside the school.

“Hey Brad!” they said simultaneously, blushing as he stared at them in bewilderment. He only knew them through his sister’s work on the squad - Marjorie and Celia, or Marie and Courtney, something like that.

“Hey girls,” he said cautiously, and Mary ... or Martine - the ‘M’ one, anyway - rolled her eyes affectionately.

“Don’t tell me you’ve forgotten,” she said. “We were going to have a Lingroup meeting before class.”

It took Brad most of the day to piece it together. Whatever was happening wasn’t just limited to his house - he had somehow become one of the most popular people in the whole school.

What’s more, translating ancient languages had become the preferred pastime of the cool kids, while being a cheerleader was left to losers.

Losers like his sister.

The entire day continued like that - all the teachers who had previously hated him were warm and affectionate, the ex-football players (handsome, buff men who were now passionately into board games and Dungeons and Dragons) invited him to eat lunch with them, and any time Brad forgot someone’s name (which was constantly) it was waved off and forgiven immediately.

It wasn’t until he got home - far later than he normally did, due to an invitation to hang out at the mall - and saw the ancient tome sitting on his desk that he worked out what was happening.

The book.

It was impossible. Of course the whole situation was impossible.

Somehow, the book had switched his sister’s life with his own.

A greedy look came into Bradley’s eyes as he turned to the next page. Where the image above “high to low” had been vaguely sexual, the next page was explicit. It featured a silhouetted man pinning a naked woman against the wall, dominating her with his body language. He recognized some of the text - “switch, switch, switch” and “low to high, high to low” were repeated, but there was another phrase, in big letters below the image.

Never before had Bradley worked so hard on a translation. He pulled up IM, and got the help of all the ex-cheerleaders (now linguist nerds) who were online, and within an hour, he worked out what it said.

Looking around to make sure no one was watching, he quietly read the ancient text.

“Switch, switch, switch. Switch, switch, switch. Low to high, high to low.”

Again, the wave of fatigue hit, but with all his effort, he struggled to overcome it, and finish the text.

“But growth, and more; more than before. But more, and growth, and switch them both.”

He had barely gotten the last word out of his mouth when a blinding light shot out of the book, propelling him backwards onto his bed, where he immediately fell into the deepest sleep he’d ever experienced.


	Chapter 3

Bradley awoke to a strange sight. Lying beside him on the bed was Maggie (or May, or Melissa ... he had never actually gotten around to learning her name).

She was fast asleep, and she was totally naked.

He just lay there for a minute or two, appreciating her body - her tits weren’t as large as his sister’s, but they well shapely, suited her frame ... besides which, he was never going to complain to a pair of tits in his bed.

Her eyes fluttered open, and she smiled shyly at him.

“Hey stud,” she said, and he just grinned. “Do you think we have time for another round before breakfast?”

Before he could answer, the door open, and his mother entered, carrying a tray full of food. Her eyes widened slightly at the sight of the two nude teenagers, but she smiled and made a show of shutting them.

“I’m not looking,” she said with a laugh. “I know how you kids get. Guide me through the mess, will you?”

Monica - or whoever - chuckled, and gave Brad’s mother directions through their clothes, which lay scattered throughout the room. Soon, she was at the bed, handing over two plates of bacon, eggs, toast and hash browns.

“So nice to see you again, Maddy,” she said as she closed the door. “You’re welcome over any time.”

“Your mother never remembers my name,” the cheerleader said with a grin. “How many girls do you bring home in a week?”

After they ate, the two got dressed and Brad’s mother gave them a lift into school.

“I’m sorry about Caitlin,” she said in a whisper as they piled into the car. Brad looked to see what she was referring to - Caitlin was standing at the top of the stairs, staring lustfully at the pair, a sneer on her face. She was wearing an oversized black T-shirt, and her hair was stringy and matted.

“It’s fine,” May whispered back. “I just feel sorry for her, honestly.”

Those words rang around Bradley’s head all day. As soon as he arrived, female students flocked to give him a hug. One of them grabbed his hand and pulled him into the girl’s bathroom - less than a minute later, she was on her knees, totally nude, smiling up at him as she pulled his hardening member out of his pants.

As she enthusiastically fellated him, a small crowd of students (and, Brad noticed nervously, one teacher) gathered to watch. It didn’t slow her down, and so Bradley tried not to let it bother him.

When he came, pulling out of her mouth and spraying his seed all over her body, the throng of onlookers applauded.

The rest of the day continued in a similar fashion - Brad was basically king of the school. The boys loved him, the girls wanted him, and it seemed like some of the teachers were even flirting with him.

He continued pushing, trying to find a limit, but no matter what he did - grope girls during gym, distract his math teacher by flaunting the outline of his erection through his pants, even pull the head quarterback’s girlfriend away from him and start making out with her in front of him - no one seemed to care. It was all met with affectionate smiles and appreciation.

When the final bell of school rang, he declined all the offers of socialization (and companionship), and spent ten minutes seeking out Gabby to cancel the date they’d apparently arranged for that evening.

She was disappointed, but when he promised a rain check, she perked up again. He suspected he could text her at 2am and she’d come around for their “date”, but promised her dinner and a movie on the weekend to make up for the last-minute cancellation.

Instead of spending time with his hordes of new friends, he headed straight home, and knocked on his sister’s door.

“What do you want?” she said with a lustful stare. The sight of her acne (which hadn’t been apparent until he got up close) made him grimace, but he had an agenda.

“Take your top off,” he said, and a look of gleeful arrogance crossed her greasy face.

“Back for more, are you? Well, you know the rules...”

Brad stepped into the room and closed the door. Ignoring his sister’s objections, he pulled her shirt up, and was delighted that the changes to her face and wardrobe hadn’t affected those perfect tits.

“What the fuck are you doing?” she said with a splutter, once her face was visible again. “Is this some kind of trap?”

“Get on the bed,” he said.

She eyed him suspiciously, and - just as he had a few days earlier - glanced around to try to find a hidden camera.

“It’s not a trick,” he said with a sigh, trying to work out what would have convinced him earlier in the week. “This is a once-in-a-lifetime opportunity. Clothes off, get on the bed.”

Within a few seconds, his sister was naked, staring at him apprehensively. Her body was everything that he’d remembered it being, and from the way she was staring, he knew his hardness was visible.

“No one ever learns about this,” he said as he began unbuttoning his shirt. “We do it whenever I want, wherever I want, and you do exactly as I say.”

Caitlin opened her mouth to object, but he could see her contemplating his offer. After a moment of silence, she closed it again, and nodded.

She was still suspicious, but it was obvious that she was willing to risk it. At worst, she’d get in trouble - at best, all her incestuous fantasies came true.

“Mom and Dad will never suspect me of anything,” he said, kicking off his shoes. In truth, he wondered if they’d even care - his escapades at school had given him a real feeling of invincibility. “So it’s up to you to make sure they never find out what’s happening. Understand?”

His sister nodded, and her eyes dropped to his erection, slowly coming into view as he lowered his perfectly-creased pants. He couldn’t help but grin as she licked her lips at the sight of his hardness.

The moment he gestured, she was on her knees in front of him. Bradley had already cum a few times that day (he’d been unable to resist the smorgasbord of pussy suddenly available to him at school) but her lips wrapped around his cock was a fantasy come true, and he paused to revere the moment.

“Protection is your responsibility,” he grunted after a few heavenly minutes of his sister’s mouth sliding up and down his thick rod. “I use a condom with everyone else, but with you, it’s bareback or it doesn’t happen at all. Understand?”

Through a mouthful of his cock, she responded in the affirmative. Reaching down, he started pulling at her thick teats, enjoy the ripples of pleasure that passed through her body at his rough handling of her nips.

It wasn’t long before her talented mouth had brought him to the edge of pleasure. He briefly considered the benefits of cumming on her tits, or watching her swallow his seed down, but decided to fulfill another long-held fantasy instead.

“I’m going to fuck you,” he said, and almost as soon as the words had left his mouth, her tits were pressed against the blanket, her ass and unshaved pussy in his face.

“Do it,” she said, her voice muffled by the pillow her face was pressed against. “Do it, you nasty little slut.”

Bradley wasn’t quite sure if she was trying to insult him or turn him on, but he ignored his sister’s crude words, lined himself up at her entrance, and started pushing forward. She shook with pleasure as he entered her, and almost immediately her cunt began clenching and spasming around his hardness.

“Oh god yes,” she shouted into the pillow. “Oh yes oh yes oh yes. Oh, fuck me! Fuck me, you whore!”

Making a mental note to talk to her about her language, Bradley did as she ordered and began fucking his sister in earnest. Years of frustration and desire were released as he roughly pounded into her; the less he cared about her pleasure, the more she seemed to enjoy the fuck.

She was tight, wet, and warm, and before long her vibrations managed to coax an orgasm out of him. He gasped, pushing into her - hard - and tightly grabbed her hips as he unloaded into her, enjoying the knowledge that this was the best sex she’d ever had ... and, likely, would ever have.

When he was done, he pulled out of Caitlin and ordered for her to clean him up. To his surprise, she didn’t even hesitate, seeming to relish the opportunity to take his cock into her mouth once more.

“Any questions?” he said with an arrogant leer, enjoying the sight of his sister’s big blue eyes looking up at him, her cheeks bulging as she tasted their mixed juices.

She removed his softening cock from her mouth briefly. “Anal?”

“Of course. Yours, not mine.”

“Fine,” Caitlin muttered, and he saw a flicker of hesitation in her eyes, like she had something more to say.

“What is it?” he pressed, but it was only after another thirty seconds of sucking his now-soft cock that she managed to summon the courage to ask.

“Well...” she said, and he slapped her firmly on the ass.

“Speak up.”

“It’s just ... why are you doing this?”

The question took Bradley by surprise, and he paused, thinking about it for a moment before giving the answer he realized he’d always wanted to hear.

“Look, sis - you may be a pervert, but I love you. You’re **our** pervert, and you deserve happiness as much as anyone.”


	Epilogue

“Bradley, cut that out,” his mother said, but her voice carried no real annoyance.

“C’mon Mom, I know you like it.”

“Stop!” she said with a huge grin.

Brad’s father looked up from the couch across the room.

“Please, honey,” he said. “I’m trying to read.”

With that, his head returned to the newspaper, and Brad’s hand returned to his mother’s chest.

“Fine,” she said with a sigh. “But don’t forget I’ve got to get dinner on soon...”

“Caitlin can do that. Caitlin!”

His voice carried across the house, but he noticed it didn’t seem to disturb his father’s reading in the slightest. Within a minute, Caitlin had appeared, a hopeful look on her face.

“I want you to take care of dinner,” he said, slipping his hand up his mother’s shirt.

“Bradley!” she said, her attempt at an authoritative tone dramatically undermined by the lustful pant that immediately preceded it. “I don’t know if ... oh!”

As Caitlin begrudgingly headed towards the kitchen, Brad’s hand had found his mother’s nipple, and given it a firm tug.

He’d been experimenting with groping his mother for a few weeks now. It didn’t seem to matter whether they were in public, in private, even if there were other people around - her reaction was always the same. A mild scolding, like one would give a child for pointing.

The presence of her husband hadn’t even made a difference, and so Bradley had been horny on the couch when he decided to try pushing things a little further.

“Please,” she whimpered slightly as he began unbuttoning her blouse and removing it from her. He knew exactly where Caitlin had gotten her tits. “Bradley, I ... oh!!”

As his mouth latched onto her nipple for the first time in over a decade, his eyes flicked over at his father, continuing to read the paper as if nothing unusual was happening at all.

“Are you nice and wet for me?” he hissed, and after a pause, his mother responded in the affirmative. “Good,” he said, reaching between her legs.

“You’re such a good boy,” she moaned, her eyes losing focus. “Such a good...”

The rest of her sentence was lost to an orgasm, as Bradley managed to one-handedly unbuckle his pants and bring his erection into view.

“God, Mom,” he said with a grin as he slid into her for the first time, enjoying watching her quiver with an easy orgasm. “You’re such a pervert...”

All she could do in response was nod.
