(CW: incest (mother-son))

===

Aunt Kay clearly wasn’t used to travelling naked in a car on public streets.  She was seated in the back, and she kept trying to slide down on her seat or lie sideways so that drivers in adjacent cars wouldn’t see her naked tits.  Ethan had to keep instructing Melissa – who was just as nude – to stop the car until Aunt Kay straightened up again. 

On the third such occasion, he threatened to pull Aunt Kay out of the car and beat her tits by the side of the road as passing motorists watched, and after that Kay behaved herself.

To pass the time, he had Kay record a video on her phone.  She was instructed to angle the phone so it clearly displayed her face and tits, and then make the most ridiculous misogynist rant she could.  

Ethan told her that if it wasn’t crude enough, or she didn’t sound like she believed it, he would make her get out of the car and masturbate to the edge of orgasm by the side of the road, to see if she gave a better performance with a wet cunt.

Kay clearly believed that Ethan meant it, because she enthusiastically babbled about how women were stupid animals that only existed so that men could fuck them for nearly half an hour before Ethan told her to stop and send him the video.

It was just more insurance, really, to ensure that if she changed her mind, her life and her career would be ruined. 

When they reached Ethan’s house, Ethan had both women crawl on all fours from the car to the front door.  It had occurred to him that he didn’t really care if the neighbours saw.  There was no crime in being briefly naked in one’s own front yard, except perhaps for indecent exposure, and if the cops were called he would enjoy having Melissa and Kay explain to police that they were sluts and that they would be good girls in future.  More likely, the neighbours would either be aroused by the women’s slutty display, or quietly disgusted by it, and Ethan didn’t care about them either way.  

And it was important to reinforce to Melissa and Kay that they were disgusting sluts everywhere they went – not just behind closed doors.  They would learn that wearing clothes in public and walking upright was a privilege, not a right.

Melissa was nervous and scared as Ethan led her and her sister to the master bedroom which had once been hers, and which now belonged to her son.  Everything that was happening was so degraded and so wrong.  She was the helpless sexual slave of her own son.  She had just raped her own sister on his command, and she had helped participate in Kay’s enslavement – helped to make her another pet for her son to rape.

And yet her pussy was so wet.  Ethan’s father had begun training her for this moment, and Ethan himself had completed the training.  The idea of being a collared nude animal who worshipped her son’s cock and raped her sister for his enjoyment – and her own – felt *right*, in a primal way, like she had always been destined to reach exactly this fate. 

She had been forced to fantasise about raping her crying, non-consenting sister for months, masturbating again and again to the same horrible idea, and now she had *done* it, and orgasmed from it, and she would be allowed to do it again and again, without regard for Kay’s consent or enjoyment, and without regard for any consequences.  It made her want to orgasm right there at the very thought of it – and then to hurt her tits and cunt until she screamed, for being so disgusting and slutty – and then to orgasm again from the pain.

She looked at Kay and she didn’t see the sister she had grown up with and loved.  She saw a pair of perfect tits, and a mouth for kissing and licking, and a tempting little cunt.  She saw a crying little fake-lesbian bitch that needed to be slapped and dominated.  She saw a toy that would be fun to rape.  She saw Kay as her son did, and she couldn’t quite remember how she had ever seen Kay differently.

She felt a wetness on her stomach, and she looked down to see that her tits were leaking milk.  A thin rivulet of white fluid was running from each and dripping onto her belly.

They had reached the bedroom, and Ethan noticed Melissa’s state at the same time that she did.

“Aunt Kay, your moo-cow of a sister needs milking,” said Ethan.  “Would you care to suck her tits dry like a good sister?”

Kay looked at Melissa and it was clear that she did not want to suck on her own sister’s boobs.  But she had little choice.

“Finger her pussy while she sucks,” Ethan instructed Melissa.  “Let’s teach her how good it feels to be an obedient whore.”

“Yes, daddy,” said Melissa meekly.  She gasped as Kay placed her lips on Melissa’s left nipple and began to suck.  Obediently she reached out, and found Kay’s snatch was wet.  Aroused?  Or still damp from previous activity?

Aroused, she was surprised to discover, as Kay responded immediately when Melissa buried two fingers in her sister’s fuckhole and used her thumb to stroke Kay’s clit.  Her whole body writhed, and Melissa could hear Kay moaning around her mouthful of udder.

Could it be that Kay shared some of the same lesbian lust for Melissa that Melissa had been trained to have for Kay?  And if so, did that make Melissa happy?  Or was it a little disappointing, because some part of Melissa found it more fun to rape her sister if she truly didn’t want it?

Ethan made sure to film the encounter between his mother and his aunt – more insurance, and maybe something to share with some privileged friends.  He didn’t touch his cock as he watched, merely letting it harden in anticipation of what was to come.

Melissa felt so good breastfeeding her sister as she controlled her sister’s arousal with two fingers and a thumb.  The only way it could be better was if her own cunt was being stuffed or licked, or – and she blushed at this – if her son’s cock was in her mouth.

“Don’t let her cum,” said Ethan to Melissa.  He hadn’t thought he would have to say this, but it seemed Aunt Kay was quite the slut, at least when it came to women.  It was perhaps unsurprising – she had been so hungry for the cunt of her younger student Gabrielle that she had allowed Gabrielle to convince her to do the humiliating things in the piss video.

Kay sucked one of Melissa’s tits dry, and then moved on to the other one.  Her whole body was writhing, her hips bucking against Melissa’s hand, and Melissa had to pause her masturbation and withdraw her hand briefly in order to obey Ethan’s prohibition on letting Kay find release.

Finally, Kay had drunk all the milk from her sister’s large udders.  She looked up at Melissa with a lust-drunk face, straining forward as if to kiss her sister’s lips.

But Ethan was ready for the next stage now.  He got up, stripped naked, and then pulled Kay away from her sister.  He flipped her onto her back, with her cunt near the edge of the bed, and then he parted her legs, stepped between them, and forced his cock into her pussy.

Melissa had done her work well.  Kay was so primed with lust that, to her immense shame and humiliation, her response to having her cunt non-consensually penetrated by her nephew’s cock – the first heterosexual penetration in her life – was to suddenly and uncontrollably orgasm, squirting all over Ethan’s groin.

Ethan laughed at her mortified expression, grateful that he had all this on camera.  Then he began to forcefully fuck his aunt’s rapehole, using his grip on her legs to pull her closer on each thrust.  

“Did you know,” said Ethan, “that your cunt girlfriend Gabriella has been replacing your birth control with fertility pills for weeks?”

Kay’s eyes widened and she began to struggle.

Without being told, Melissa moved to hold her down so her son could continue his rape.

“And unless I’m completely wrong, now is the most fertile part of your cycle,” said Ethan.  “You did beg me to breed you, after all.”

“Please, no,” moaned Kay.  

“I’m taping all this,” said Ethan, “so your daughter can watch it on her 18th birthday while masturbating, to see how she was conceived.  To see that it’s not her decision whether she’s impregnated or not.”

Kay bucked and writhed against Ethan’s cock, which only made the sex hotter.

“Don’t worry,” said Ethan.  “You’re not going to have to live with the public shame of carrying your nephew’s baby.  Once we know for sure you’re pregnant, I’ll get you to work as a prostitute for a month or so.  Only unprotected sex.  That way you’ll have enough credibility as a whore that you’ll be able to pretend you don’t know who the father is.”

He frowned.  “Although we may need you to keep working as a whore, on top of your university job, to cover the costs of your pregnancy.  We’ll see.”

He looked at Melissa.  “Do you like the idea of your sister giving birth to your granddaughter, mom?”

She recoiled at the revolting thought.  She hated feeling so disgusted and so horny at the same time.

“Tell your sister how pretty she’ll look with bulging milky tits and a baby belly, mom,” said Ethan.

“You will,” said Melissa.  “Your tits will look so hot when they’re bigger, Kay.  I can’t wait to suck the milk from them.  And you’re going to look so sexy with a baby in your belly.”  Unable to help herself, she leaned across and kissed her helpless sister on the lips as her son continued to rape her.

Ethan continued to forcefully fuck Kay, and was rewarded when she suddenly orgasmed again, despite her fear and hatred.

That was his signal to speed up.  He began to vigorously pump her – and soon he was cumming into his lesbian aunt’s womb.  

As he felt his sperm flow into her, he was certain he had impregnated her.  He had no way to know that for sure, and yet somehow he simply *knew*.  He had knocked up his own aunt.  And not just with any baby – with a daughter, and 18 years from now he would make that daughter into his fucktoy, just like her mother.

“She’s pregnant, mom,” said Ethan.  “Does that make you happy?  That you helped me rape a baby into your sister?  This is all your fault, after all.”

Melissa knew that Ethan intended to hurt her with those words, but it was only the truth.  And besides, there was another emotion she was feeling, and she knew that in this case if she told Ethan about it, there was a good chance she’d get what she wanted.

“It does make me happy, daddy,” she said.  “But also… it makes me jealous that you put a baby into my sister.”  She paused, blushing, and then added, “I want one too.”

Ethan smiled.

“I think we can make that happen,” he said.
