Luna absolutely did not want to try on slutty lingerie for her mother.

“I can’t wear these!” she protested loudly when her mother showed her the crotchless panties, G-strings and half-cup and cupless bras that Jayna had picked out from the lingerie store.

“Of course you can, honey,” said Carrie.  “Jayna told me all about it.  It’s natural for girls your age to want to experiment, and look sexy, but feel insecure about their bodies.  You’ve got nothing to feel nervous about, honey – you have a very sexy body, and these clothes are going to look gorgeous on you.”

Jayna was not present for any of this.  She’d already told Luna to act like a slut on plenty of occasions – it was important now for Luna to hear her mother encouraging her to behave the same way.  Luna and her mother were in Luna’s bedroom, with the door closed, and Jayna was standing discreetly outside, listening.

Luna did not want to undress in front of her mother for all the normal reasons of teen privacy – but also because her cunt was undoubtedly soaking wet.  Jayna had told her that she expected Luna to be aroused when Jayna got home, and Luna had probably thought that was because Jayna meant to lick her pussy or play some other game with her.  She would have been surreptitiously rubbing her cunt and thinking slutty thoughts all morning, afraid of what Jayna would do if she came home and caught her dry-cunted.

But it was not Jayna who was going to see the results – but rather Luna’s mother Carrie.

“Please, mom, this is weird…” protested Luna.

“There’s nothing weird about a mother helping her daughter try on clothes,” replied Carrie – and was that a touch of blush in her voice?  After all, Carrie had just spent the morning with her foster daughter Jayna sucking on her tits and licking her pussy.  She knew that what she was saying was a lie.

But then her voice hardened.  “Now, are you going to get undressed, or do I have to call your brother in to help you take those clothes off?”

That was the end of the argument.  Of course Luna could not bear the thought of her brother Mitch getting involved.  There was a silence, as Luna undressed in front of her mother.

After a while, Carrie said, “And the panties too, young miss.”  And then a further pause.

Jayna wished she could see Carrie’s face.  It was a big step for the older woman.  Only hours ago, Jayna had licked Carrie to orgasm while forcing her to picture her daughter wearing the slutty underwear.  Now Carrie was seeing her daughter’s nude body in the flesh – and nothing that her nipples were erect, and her pussy was visibly wet.

If Jayna had read Carrie’s psyche correctly, Carrie would, right now, be getting sexually aroused by the sight of her daughter’s body for the first time ever.  An important milestone, Jayna thought, for any mother.  

Jayna wondered if Carrie was staring at her daughter’s wet fuckhole, and imagining “licking it clean” as Jayna had done for Carrie herself.

Carrie took a deep breath.  “Now try the clothes on,” she said.  “You’ll look pretty in them.  I’ll take a picture of you wearing them so you can see how pretty you look.”

Jayna hadn’t told Carrie to take photos.  That was all Carrie’s idea.  She wondered what Carrie would do with the photos?  Delete them, feeling guilty?  Keep them to masturbate to later, as she stared at her daughter’s sluttily-decorated tits and cunt?  Surely not share them with her husband – at least, not yet.

The underwear Luna was putting on had been shoved up her mother’s wet cunt only an hour ago, and then Carrie had sucked her cunt juices from the material.  Would Luna notice?  Would she sense something was strange?  Surely Carrie was thinking about it.  What were the embarrassment and guilt doing to her?  Traumatising her?  Making her pussy wetter?  Both at once?

Suddenly a hand – a male hand – touched Jayna’s shoulder.

“What’s going on in there?” asked a voice.

Jayna turned to see Luna’s brother Mitch standing there.  She smiled brightly, sensing an opportunity for further mischief.

“Your mom bought Luna a bunch of sexy underwear and she’s making Luna try it on,” she said.  “Sssh, or they’ll hear us.”  

She pushed Mitch back down the corridor a little, towards his bedroom.

“Sexy?” asked Mitch.  “Like what?”

“Crotchless panties,” said Jayna.  “G-strings.  Bras that expose her tits.  Your mom’s going to throw out all Luna’s other underwear so she has to wear these all the time.  Or else go without underwear.”

She watched Mitch’s face as her words caused him to picture, in rapid succession, his sister in her underwear, his sister in crotchless panties, his sister’s tits, and then his sister’s naked cunt.  She was pleased by the flicker of guilty teen lust that she saw.

“Why?” asked Mitch.

“Because Luna wants to look prettier for boys,” said Jayna.  “Girls get insecure if they think boys don’t want to fuck them.  She’s worried if she gets a boyfriend, they’ll be making out, and he’ll lift up her skirt and see ugly underpants and not want to fuck her.  She wants him to see her pussy instead, and just stick his cock right in.”

Now Mitch was thinking about lifting up his sister’s skirt, and thinking about someone’s cock penetrating his sister’s cunt.

“That’s kind of slutty,” said Mitch.

Jayna pushed him further back, and now they were both in his bedroom.  She closed the door behind him.

“No, it’s pretty normal for girls,” she said.  “Girls spend a lot of time thinking about boys fucking them.  Luna fantasies about all kinds of boys fucking her.”

She pushed Mitch back, causing him to sit down on his bed, and then she sat in his lap, turned 90 degrees to him, her arm around his neck, her face near to his.

“I had no idea,” said Mitch.  “She was kind of boy crazy a bit when she was younger, but…”

“Oh, yeah,” said Jayna.  “She’s kind of a whore.  We share the same bed so I hear her moaning in her sleep and playing with her pussy when she thinks I don’t know.”

Mitch blushed a little.

Jayna wiggled her butt a little against Mitch’s lap, and was pleased to discover that his cock was hard.  She felt it twitch as she rubbed against it through Mitch’s pants.

“Have you ever fucked any girls, Mitch?” she asked mischievously.

Mitch went red.  “Ah… no. Not yet,” he admitted.

Jayna bit her lip.  ‘Would you like to?” she asked – and wiggled her ass against his cock some more.

She knew what he was thinking.  Was this a rhetorical question?  Or was Jayna suggesting that *she* would fuck him?  It was best that he think about what it might be like to fuck his foster sister, and decide that it was something that he wanted.

“Um…” he said.

“Do you ever have fantasies about Luna?” she asked him quickly.

Surprised at the sudden change in direction, Mitch didn’t know what to say.  “I don’t know…” he mumbled.

“Because she fantasises about you,” said Jayna.

Mitch’s cock twitched against Jayna’s ass.  Hard.

“What?” he asked, suddenly alert.

“Look,” said Jayna.  “I’ll show you.”

She took out her phone and queued up the video.

It was Luna , visible from the waist up, and topless, her tits on display.  She was obviously aroused, her nipples erect, her face flushed. 

“I like cockteasing my brother,” she said.  “I want Mitch to fuck me.  I want him to cum inside me.  I want to taste his cock.”

Jayna knew that what she was doing was irreversible.  No matter what happened from here, Mitch would never forget seeing this video, and it would colour every future interaction he had with his sister.  She was irrevocably sexualising Luna in her brother’s eyes.

It made her pussy wet, and she wiggled her ass happily against Mitch’s cock, before stopping the video and putting her phone away.

“Holy shit,” breathed Mitch.

Jayna made a stern face.  “You cannot ever, EVER tell Luna that I showed you this video.  She would kill me.  And then kill you.  You HAVE to keep it a secret.”

“I promise!” said Mitch immediately.  “Can I see it again?”

Jayna bit her lip again.  “No, I shouldn’t have showed you the first time,” she said.

“But… she really wants to fuck me?” asked Mitch.

“Yes,” said Jayna.  “But she will *never* admit it to you.  She’s way too embarrassed.  She’ll take it to the grave.”

She paused, and then said, “Do you know what the deal was with my father?  Like, why I’m here with your family.”

Mitch blushed.  “He was… a rapist, wasn’t he?  He raped all those girls.”

Jayna nodded.  “And… you know…. Sometimes he made me watch.”

She felt Mitch’s cock twitch again, and she wiggled her ass against it some more to encourage him.

“What was it like?” asked Mitch.  His voice was a bit breathy now.

“It was hot,” said Jayna.  “I know that’s wrong, but it was.  There’s just something so sexy about a girl being *taken*, whether she wants it or not.  My father would tie them down, and spread their legs, and rip off their panties.  And then if their pussies were wet, he’d rub their panties against their pussy, and then stuff the panties into their mouth as a gag, so they could taste what a slut they were.”  She paused.  “I really shouldn’t talk more about it.  The government people said it could be… what’s the word?  Re-traumatising.”

Mitch didn’t sound traumatised.  He was practically bucking his hips underneath her to try and press his cock harder into her ass.  Jayna pretended she didn’t notice.

“But, like, most girls really didn’t want to be raped,” said Jayna.  “But only most girls.  There were some girls, they’d say no, and they’d kick and struggle, but then when my dad put his cock in them, they’d start to buck against him and go wild, like they were desperate to be fucked, and they’d cum from it – multiple times.  And my dad said that’s because some girls really want to be raped – because they’re too shy to admit they want to be fucked, and they can’t ever ask for it because they’re embarrassed, so they just need a man to take away their choices and force them to enjoy the thing that they secretly want.”

“And you think… Luna might be like that?” asked Mitch.

Jayna giggled.  “I know she is,” she said.  “Like, if you felt her ass or tits, she’d call you a perv, but she’d get so wet.  And if you called her a slut or a whore, she’d blush – but she’d probably masturbate about it afterwards.  And if you just slapped her, and bent her over the couch, and *raped* her, she’d go wild for it”

“Even though I’m her brother?” asked Mitch.

“Especially because you’re her brother,” said Jayna.

Mitch’s cock was so hard it must have been hurting him.  Jayna looked down suddenly.

“Are your pants okay, Mitch?” she asked.

Mitch’s face was bright red.  “They’re fine,” he said, unconvincingly.

“It’s okay, you don’t have to pretend,” she said.  “I know your cock is hard.  It’s only natural – I’ve just been talking about how much your sister cockteases you.  That’s exactly what she wants to happen.”  She leaned in close, and whispered in Mitch’s ear.  “Do you want me to take care of it for you?”

Mitch went even redder, if that was possible.  “What do you mean?” he asked.

“You know what I mean,” said Jayna.  “With my mouth.  You can cum in my mouth.  I don’t mind, really.  That’s what sisters are for.”  She wiggled her ass on his cock again.  “Do you want me to take care of it?”

Mitch’s voice was hoarse with lust.  “Uh… I guess.  Yeah.  That would be… really good.”

Jayna smiled, and dropped to her knees next to his bed.  She unzipped his jeans, and then pulled them down to his ankles, and off.  Then she reached into his underpants and found the warmth of his cock – stiff as a board, and yet with such soft skin.  The tip was soaked with pre-cum and there was a wet patch from it on the front of his briefs.

“Okay, you can cum in my mouth,” said Jayna.  “But we’re going to play a game, okay?  If you want to cum in my mouth, you have to force me.  What you do is you grab my hair, and you pull me down on your cock, and you don’t let me up until you cum, no matter what I do.  It doesn’t matter if I’m struggling, hitting you, or choking – you hold me there until you get what you want, okay?”

“Ah, okay…” said Mitch.  He reached out and grabbed a handful of her fine blonde hair in each hand.  “Like this?” he asked.

He had a good natural instinct – he had grabbed her hair tightly at the base, just like she liked.

“That’s right,” said Jayna.  “Now pull me down.”

Jayna had actually never sucked a cock before.  She’d tasted her father’s cum, fresh from the pussy of a freshly raped girl, on more than one occasion, but her father had never directly violated Jayna herself (no matter how much she had fantasised about it).  She had, however, watched her father do exactly what Mitch was about to do, to crying, non-consenting women, and she had loved it best when the women had struggled and moaned and gagged, and her father had ignored them and used them as if they were nothing but objects, uncaring of their comfort or consent.

As Mitch drew her down towards his cock, she opened her mouth, and a moment later his dick was inside her.  Jayna marvelled at how *right* it felt, as though her mouth had been designed specifically to be plugged by the shape of a man’s cock, and she moaned as she tasted his pre-cum, and for a moment forgot that she was supposed to be struggling.

Then Mitch began to thrust, shoving his cock deep into her mouth, his grip on her hair iron and unyielding, and the first time the tip of his dick touched the back of her throat she felt herself start to gag, and then she really *was* struggling, honestly trying to get away.  She slapped at his knees and tried to pull back, but Mitch wouldn’t let her go.

“Fuck,” he moaned.  “Oh fuck… Luna…”

The knowledge that Mitch was fantasising about his sister would have pleased Jayna more if she weren’t choking.  She slapped ineffectually at Mitch’s hands, desperate to be able to breathe without a throatful of dick.  She was aware that, despite everything, her pussy was getting wetter, but it was hard to think about that now.

“Yes,” moaned Mitch, fucking his cock deep into Jayna’s throat.  “Yes.  Fuck, yes.”

It became clear to Jayna that Mitch wasn’t going to release her, and at some point a switch flipped in her head, and her panic became submission.  She felt herself go limp, and felt her throat muscles relax, and then suddenly it wasn’t so bad.  She was just an object, whose purpose was to please Mitch’s cock, and that was all she was good for.

Her submission seemed to be the final trigger that Mitch needed, and suddenly he was cumming, squirting cum down her throat.  Jayna was able to pull back enough that she was able to swallow the sperm, rather than having it fill her lungs – and then, suddenly, unexpectedly, she was cumming too, a completely hands-free orgasm from the knowledge that she had just experienced her first rape from the perspective of a victim.

She had taught Mitch to rape her.

Her father would be so proud.

There was something missing, though.  Something her father would have done afterwards.   

She looked up at Mitch, who was still gasping from the intensity of his orgasm, semen dripping from the tip of his dick.

“Slap me,” she told him.  “Slap me hard across the face, and tell me it’s because I struggled, and because I was a disappointing fuck, and that I need to do better next time.  And then wipe your dick clean on my face.”

He looked at her blankly, and for a moment she thought she was going to have to repeat herself.  But then Mitch snapped into action.

His hand lashed out, and backhanded her across the face.  It stung.  It felt good.  She thought it might even leave a mark.

“That’s because you struggled,” he told her.  “And because you were a disappointing fuck.  Do better next time.”  And then he stood, and grabbed her hair again, and wiped his cock back and forth across her lips and cheeks, leaving a long smear of cum, before using her hair to wipe the last of the sperm from his shaft.

Afterwards, though, he grinned awkwardly.  “But… you weren’t bad, though,” he said.  “That was so good.  Your mouth was amazing.  And when you struggled – I liked it.”

She smiled back at him.  “We shouldn’t really do that very often,” she told him.  “But… I liked it.  And if your cock gets hard like that, it’s probably my fault, or Luna’s, for cockteasing you, so just… do what you need, to take care of it.  You don’t have to ask first.”

He may have only just cum, but his cock was twitching again.  “Okay,” he said.  “I will.”  He paused.  “Are you sure I can’t see that video of Luna again?”

“I’ll tell you what,” said Jayna.  “How about a homework assignment, to show you’re serious?”

He scrunched up his face at the word “homework”.  “That sounds stupid.  What do you mean?”

“An essay,” she said.  “Two thousand words.  The topic is ‘Why Luna deserves to be raped, and how I would rape her’.  If you write that for me, I’ll play with your cock while I read it, and then show you that video again – and maybe a little something extra.”

A boy would do anything to have Jayna play with his cock – even homework.  “Okay,” he said.  “It’s a deal.”

She smiled, and turned to leave his room.  Outside, she could hear Luna protesting as her mother carried all her non-slutty underwear to the garbage hopper outside, to throw it away forever.

“Oh, and Jayna,” said Mitch suddenly.  “I know you said it might be, like, re-traumatising… but if you ever wanted to share any more stories about your dad raping those women… I’d be willing to listen.”

She turned back, and gave him a bright, adoring smile.

“Sure,” she said.  “I’d like that very much.”

5 thoughts on “Story: The Foster Girl, Part 8

    1. This story is still ongoing – keep watching for new serial chapters, and when it’s eventually concluded it will be collected in a single book. However, if you want more of this kind of story, featuring incest and corruption, then pick up my book “The Etrebor Exchange” in the ATR store!

  1. Any chance this can be written as a novel length story as opposed to small chapters? This story is turning out to be my favourite

    1. I don’t ever set out to just write a novel, and when I do I tend to end up getting writer’s block and abandoning it. (Premium Members have access to several substantial but unfinished efforts in this space.) Also my business model doesn’t really allow me to just sit and write a whole novel and only release it when it’s done, if only because I need to see that there’s sustained interest from readers along the way to justify a story of that length.

      Novella and novel-length stories happen because I just keep writing a “next chapter”, in a serialised fashion, until they reach some sort of natural conclusion, and I’m guided in which stories to write new chapters of by the requests of my paid Premium Members of longest standing. (Currently I’m working on the preferences of people who were members in January and February 2022.)

      The Foster Girl is fairly popular, and new chapters will probably keep coming, but I’m afraid you’ll have to keep reading in a serialised fashion, possibly with long gaps between new chapters.
