Luna’s mother Carrie was a heavy sleeper, and Jayna woke up in the morning while Carrie was still sound asleep. 

Carrie’s phone was by the bed table, and Jayna picked it up and idly played with it. To her delight, Carrie didn’t bother to use a phone lock or passcode – but to her disappointment, she couldn’t immediately find anything embarrassing or humiliating stored on the phone. 

She shrugged, and then pulled back the bedcovers to expose Carrie’s sleeping, nude body. She gently tugged Carrie’s legs apart, to better expose her pussy, and then used Carrie’s phone to take a full-body nude photograph of her. She then took a photo of herself in the mirror – also nude – and then lay back down in bed and photographed them together, clearly nude, in a lesbian embrace, with Jayna’s lips inches from Carrie’s nipple. She sent copies of all the photos from Carrie’s phone to her own, and then put the phone down, and began to suck on Carrie’s breast, while gently massaging Carrie’s pussy. 

Carrie started to moan, and then woke up. Her eyes struggled to focus on Jayna – and then they widened with alarm, and pushed her away. 

“Oh, no, honey, you can’t,” she said, a note of panic in her voice as she began to remember the previous night. 

“Why not, mommy?” asked Jayna. 

“It’s wrong,” said Carrie. “We shouldn’t have. You can’t…” 

“Wrong?” asked Jayna. “Like what my father did?” 

Carrie’s face went pale as she thought of what she knew of Jayna’s father – who had been a serial rapist. 

“No,” she said. “I mean…” 

“Will you… will you go to the police?” asked Jayna, in horror. 

Carrie’s face went even whiter at the mention of police. 

“No!” she said. “But… it’s not normal…” 

“Is it me?” asked Jayna. She was a masterful actress, and managed to bring tears to the corner of her eyes, her face mask of misery. “It’s my fault, isn’t it? I’m a slut… just like my daddy said… a disgusting whore…” 

“No!” exclaimed Carrie. “No! No, honey, there’s nothing wrong with you. I’m sorry… you’re perfect. We love you. I love you. But… people wouldn’t understand…” 

“Then we won’t tell them,” said Jayna. “It will be our little secret.” And she put her mouth back on Carrie’s nipple and began to suck, and pushed a knee between Carrie’s legs, pressing firmly against the older woman’s cunt, and just like that Carrie’s objections ceased. She made a little moan, and blushed, and then she began to cradle Jayna’s head against her bosom, and discreetly hump her cunt against Jayna’s knee. 

After a while Jayna brought her hand back to her foster mother’s groin, and began to masturbate her with her fingers, but this time she didn’t let Carrie cum. When she judged that the older woman was on the verge of orgasm, she pulled away, and climbed out of bed. 

“Thank you so much, mommy,” she said. “And don’t worry – if you really don’t like doing this, I’ll just tell the foster agency, and I’m sure they’ll take me away and you won’t have to worry about me anymore.” 

She could see from Carrie’s face that Carrie knew that it wasn’t *Jayna* who would be taken away by authorities if anyone learned about their lesbian tryst – and Jayna felt confident that Carrie would do anything to avoid anyone ever finding out about it. She smiled cutely, and skipped back to her own bedroom – the one she shared with her foster-sister Luna. 

Luna was just waking up. Jayna closed the door, then knelt next to her and pushed her fingers into Luna’s mouth. 

Luna sucked at them obediently – but not without suspicion. She clearly thought – hoped – that she was tasting Jayna’s own cunt juices, but Jayna *had* been gone the entire night… 

Jayna didn’t bother to explain. It was enough, for now, to see Luna getting her first taste of her mother’s pussy, whether she realised it or not. 

“Tell me you love me,” she instructed, after removing her fingers from Luna’s mouth. 

“I love you, Jayna,” said Luna obediently. 

“There’s a good girl,” said Jayna. “Now, let’s go shower.” 

And she had dragged Luna – completely naked – out of her room, across the hallway, and into the bathroom before Luna could object. 

“Jayna…” hissed Luna once they were in the bathroom together. “We can’t…” 

“Why not?” said Jayna, in a voice that was quiet, but definitely not a whisper. “Your mother and brother are still in bed. And anyway, what’s wrong with two girls showering together?” 

“It’s *embarrassing*,” protested Luna. 

“Then be quiet and make sure no one hears us,” said Jayna, and pushed the protesting girl into the shower, where she quickly turned on the cold water, enjoying Luna’s immediate need to suppress a shocked squeal. 

As it turned out, Luna was *very* good at being quiet when she didn’t want anyone to know that she was naked in the shower with her foster sister, and Jayna was able to kiss Luna on the lips under the shower without so much as a squeak, and run her hands across Luna’s tits, and tweak her nipples. 

She was even able to push Luna to her knees, and instruct her foster sister “girlfriend” to clean Jayna’s pussy using her tongue. 

As Luna licked at Jayna’s snatch, Jayna decided to test her foster sister’s devotion to staying quiet. She relaxed her bladder, and began to piss on Luna’s face. 

Luna immediately jerked away, but Jayna grabbed her by the hair and held her still. It was only a little urine – barely any had gone in her mouth, and the rest was being washed off her face and cheeks by the shower water as fast as it appeared – but Jayna could see in Luna’s eyes the full realisation that she was being *pissed on* – and that although she was physically struggling, she was making not a single sound of protest.  

When she was done, Jayna allowed Luna back to her feet, and leaned forward to whisper in her ear. 

“Oh, don’t make a fuss,” she said. “It’s not like it hurt you. You’re perfectly clean, aren’t you? It’s just a little game. Sisters play games together, and girlfriends play games, and you *do* love me, don’t you?” 

Luna’s face coloured, but she knew what to say. “Yes,” she whispered sulkily. 

“Good girl,” said Jayna. She turned off the water. “Now towel off and come back to our bedroom so we can play some more games.” 

She immediately skipped out of the bathroom, practically running back to the bedroom she shared with Luna – but she diverted briefly to knock twice, loudly, on the bedroom door of Luna’s brother, Mitch. She was gone before Mitch could rise and open the door – but from within Luna’s bedroom, she heard the consequences. 

There was the sound of two doors opening – the bathroom and Mitch’s bedroom – and then a horrified squeal from Luna, and then Luna came racing into the bedroom, slamming the door behind her. 

She had a towel, but it was clutched to her chest, rather than wrapped around her body. As Jayna had hoped, Luna had tried to run back across the corridor to her room without properly covering her body – and her brother had seen. 

“That creep!” Luna exclaimed. “Mitch *saw* me! He saw my tits!” She took a deep breath and whispered, “It’s a good thing he didn’t see us together.” 

Jayna just smiled, and agreed that Mitch was a creep. She didn’t know if he was or not – she hadn’t yet spent much time with Luna’s 19-year-old brother – but honestly it would suit her purposes if he *was* a creep. 

After all, she intended to teach this entire family to live according to the teachings of her father – men and women both. 

“I’m confused, though,” said Jayna, as the two girls dressed. “Didn’t you say you wanted to *fuck* your brother?” 

Luna was in the process of putting on a T-shirt and a skirt – though no panties, of course, because Jayna would not allow them. She blushed, confused. “You… you made me say that,” she said. 

“I don’t think so, Luna,” said Jayna. “You said it the other day. When you were staring at my pussy and rubbing yourself. You practically chanted that you wanted to suck your brother’s cock. And I remember you saying that you thought his cum would taste good.” 

Jayna was not making an effort to be quiet, and Luna was looking at the closed door in terror, as if her brother might burst through at any moment.  

“Please,” Luna said, “be quiet!” 

Jayna looked offended. “Don’t tell your girlfriend to be quiet, Luna,” she said. “That’s rude. Do I have to discipline you?” 

She didn’t even have to suggest what that discipline might be. Luna clearly could imagine things that were far more humiliating than anything Jayna could think of off the tip of her tongue, because she went white. 

“No,” she said. “I’m sorry…” 

Jayna finished pulling on her own top – the sexiest and tightest top among her currently clothing options, which wasn’t saying much, as she hadn’t brought nearly enough options into foster care from her former home. 

“Just admit you like cockteasing your brother, and we can move on, Luna,” she said. “I don’t know why it’s such a big deal.” 

Luna stood with her face red, and her fists clenched. Everything about this conversation made her feel dirty and ashamed, and she just wanted it to be over – and she had come to learn that such conversations would *not* end – and would only grow louder and more degrading – unless she gave Jayna what she wanted. 

“Fine,” she said. “I enjoy cockteasing my brother.” 

“There you go,” said Jayna. “It’s okay, I totally understand. He’s cute.” She bounced over to Luna and took her by her hands, kissed her briefly on her lips, and then said, “Hey, do you want to play a game with Mitch?” 

Luna did not, in fact want to play a game with Mitch – or with Jayna – but she knew she didn’t dare say no. 

“What game?” she said.  

“Truth or dare,” said Jayna. “Three rounds. I’ll go first. You tell me something that I have to go say to Mitch truthfully. He’s out there in the lounge, I think, playing videogames on the XBox. I have to say the truth about what you tell me. But if it’s too embarrassing for me, I say ‘dare’, and you give me something I have to *do* instead.” 

“Won’t he think it’s weird?” asked Luna. 

Jayna shrugged. “Who cares? He’s a boy.” 

Luna squirmed. She didn’t like this, but couldn’t say so. 

“Go ahead,” said Jayna. “What’s my truth?” 

“I don’t know,” said Luna. “Um… I guess you have to tell him you think he’s cute.” 

Jayna smiled. She left the bedroom and went to the lounge, where Mitch was indeed videogaming. She climbed up onto her knees on the couch next to him, leaned towards him, and whispered in his ear seductively. 

“Hey, Mitch – I think you’re cute.” 

And then, as he paused his videogame in surprise, and turned towards her, she jumped up and ran away giggling, closing the bedroom door behind her. 

“Your turn,” she said to Luna. 

“What do I have to say?” asked Luna. 

“Tell him you let a girl piss on your face,” said Jayna. 

Luna’s eyes went wide. “I can’t tell him that!” she said. “That’s not fair!” 

“I did your thing!” protested Jayna. “As if that wasn’t embarrassing! You didn’t give me something easy to say, like ‘I like orange juice’ or something. Now it’s your turn!” 

“I can’t!” protested Luna again. 

“Okay – then dare?” said Jayna. 

“Dare,” agreed Luna. 

“Go give him a kiss on the lips,” said Jayna. 

Luna still clearly didn’t like this option. 

“It can be just a peck,” she said.  

Luna still didn’t like it. 

“Or I can tell him about what happened in the shower instead?” offered Jayna. 

That did the trick. “No! Fine!” exclaimed Luna. She ran out of the room, gave her brother a quick, surprising peck on the lips, and ran back. 

“Luna? What’s going on?” yelled Mitch from the lounge. 

“Nothing!” yelled Luna. “Shut up! Don’t worry about it! It’s nothing!” 

“Good girl,” said Jayna. “Second round – my turn. What’s my truth?” 

Luna pouted, her face sulking. “Tell him you’re a cruel bitch,” she said.  

She clearly didn’t expect Jayna to take her seriously, but Jayna said, “Okay!” 

She went back to the lounge and climbed up on the couch again. This time Mitch was looking at her, and as she leaned forward she was keen to give him a view down her neckline, into her pretty teen cleavage. 

“Hey Mitch,” she said, “I’m a total bitch. And I’m *very* cruel to your sister.” And then she giggled, and ran away again. 

“Your turn now,” she said, back in Luna’s room. “Go tell him that you want to suck his cock.” 

“I don’t!” protested Luna. 

“Don’t lie to me, sister,” said Jayna, “or else I’ll tell him *all* the things you’ve confessed to me. Not just about him – your father too.” 

Luna made a distressed, trapped moaning sound. 

“Are you going to do it?” asked Jayna. “Or do you want a dare? It will be a worse dare than the first one, mind.” 

Luna kept squirming. But she couldn’t tell her brother she wanted to suck his cock, so she said, “Dare.” 

Jayna pressed a pen from Luna’s desk into Luna’s hand. “Go out to the lounge, and stand between your brother and the TV screen. Turn to face the TV, then drop the pen on the ground deliberately. Then bend at the waist to pick it up.” 

Luna’s hands jumped to cover her buttocks, without thinking about it. “I’m not wearing panties!” she protested. “He’ll see my…” 

“He saw it all this morning, didn’t he?” asked Jayna. “And he’s your brother – surely he’s seen it lots of times?” 

But there was a difference, Jayna knew, between Mitch seeing his sister’s naked body in passing, from a distance – as compared to her deliberately and provocatively putting her naked ass and pussy only a couple of feet from his face. 

And yet, it was better than telling Mitch that she wanted to suck his cock. 

Her face bright red, Luna walked awkwardly out into the lounge, and did as she was told. She faced the TV, she dropped the pen, she bent forward – and her skirt came up, giving her brother a perfect view of her ass cheeks, her anus, and her pussy mound. 

Her wet, aroused pussy mound. 

As soon as she had the pen, she ran back to the bedroom without looking at her brother, her cheeks burning with humiliation. 

“Third round,” said Jayna. “What’s my truth?” 

“Tell him that you’re making me do this,” wailed Luna. “Tell him it wasn’t my idea.” 

Again, Luna must have expected Jayna to say no – but instead she said, “Okay!” 

She went back to the lounge and climbed up on the couch. By now she had Mitch’s full attention – and when she leaned forward she deliberately put a hand on Mitch’s groin. She could feel his cock through his pants – rock hard, aroused by his sister’s display. 

“I’m making Luna do this,” she whispered to him. “And she’s letting me. She’ll do absolutely anything I tell her to.” And she smiled this time – no giggles – and then deliberately squeezed his cock, before getting up and walking back to the bedroom. 

“Your turn,” said Jayna. “And I’m going to go easy on you. You don’t have to tell him you’re a lesbian rapist slut. You don’t have to say you want to suck his cock and swallow his cum. You just have to tell him you think he’s sexy, okay?” 

“I can’t tell my brother that he’s sexy!” wailed Luna. 

“Of course you can,” said Jayna. “It’s a compliment. It’s nice. I’m being merciful here. I said the worst things you could think of, without argument, and you haven’t taken the truth option even once. If you call dare again, I promise you it will be a lot worse than the last one.” 

Luna made a distressed, unhappy sound – but then said, “Fine.” 

She walked back to the lounge, knelt in front of her brother, looked him in the eyes, and said, “I think you’re really sexy.” And then, blushing furiously, she ran back to the bedroom. 

“Good girl,” said Jayna. She sat on the bed and spread her legs to reveal her own panty-less cunt. “Now why don’t you reward yourself with a nice orgasm? Sit on the floor and look at my pussy, and tell me about how you want to suck your brother’s cock, and you can rub your cunt until you cum, and then lick me to orgasm afterwards.” 

And while it was nice to hear Luna begin to chant that she wanted to suck Mitch’s cock as she fingered her twat, it was unnecessary. The real work had already been done. Today, Luna had put the idea in her brother’s head that he could think of her in a sexual way – and Jayna had given him the idea that, if he wanted to act on those thoughts, Jayna could make it happen. 

She looked down at Luna’s face as her foster sister masturbated, and tried to picture what expression Luna would have when her biological brother raped her for the first time. She couldn’t decide if Luna would look prettier crying, blushing, or orgasming. 

All three, she decided in the end. Luna would look prettiest crying and blushing while she orgasmed from her brother’s cock.

  1. I love how Jayna made Luna suck her mom’s juices off her fingers, but it’s the only time its happened even in the next few times. I assumed she’d be making Luna clean her fingers like that after every time playing with Carrie, that would be a delight!
