Katy had always wanted a sister.

But her parents had broken up shortly after she was born, and Katy’s mother Sharon, who she lived with, had never seemed to have much success in finding another partner, despite her great tits and smoking body.

Sharon had been young when she had Katy, and the circumstances of Katy’s conception had apparently been not entirely consensual, and Sharon was just too scared of both men, and pregnancy, to try again.

But after Katy turned 18 an idea occurred to her. It was an idea prompted by the way boys acted around Katy – because Katy was an absolutely stunning vision of sexuality.

Katy had no particular interest in fucking boys – she thought she might be a lesbian – but she found that the promise of sexual interaction could make them agree to anything.

So he began to go on dates. She would flirt, and tease – and every date would end with her taking out the boy’s cock, putting a condom on it, and then jacking him off while she kissed him and let him play with her tits. And she would go home with a condom full of cum.

Meanwhile, she had replaced her mother’s birth control with sugar pills, and she began to crumble some of her mother’s emergency sedatives into Sharon’s dinner each night. After dinner, Sharon would retire to her bedroom, and strip naked, and fall into a deep, deep sleep.

At that point, Katy would enter her mother’s room – also naked – and climb into bed next to Sharon. She would push a vibrating dildo up her cunt and clamp her legs together to keep it in place. Then she would spread her mother’s legs, and take the condom of cum, and push the contents into her mother’s pussy.

Slowly, she would fingerfuck the sperm up into her mother’s womb, and as she did this she would kiss her mother on the lips, or suck on her tits. She knew her mother liked this, because Sharon would moan sluttily in her sleep, and buck her hips, and sometimes even return the kiss in a sleepy, disoriented way.

Katy would keep masturbating her mother until she felt Sharon cum, and at this point she would often cum herself. Then she would lower her mouth to her mother’s cunt and lick her labia and the entrance to her fuckhole, making sure there was no semen showing.

And then she would go back to bed.

She did this every night for two months, lezzing off with her mother as she pushed cum up her mother’s baby-hole, until eventually Sharon missed her period and, confused and suspicious, took a pregnancy test.

She was distraught at the result. She had no idea how she could possibly be pregnant.

At this point, Katy had to confess. After all, she needed to stop her mother from terminating the pregnancy.

“Yes, it was me,” said Katy. “Look.”

And she showed her mother a video that she had filmed, in which Sharon, nude and unconscious, was instinctively kissing her daughter on the lips and bucking her hips against her daughter’s fingers.

Sharon was aghast. She felt violated, she felt humiliated – and she felt ashamed at the sudden rush of wetness that flooded her cunt, and the flush of immediate arousal in her cheeks, as she stared at her naked daughter masturbating her on the video.

“Now, I would never blackmail you,” said Katy. “But I really want a sister, so you need to keep the baby. And now that you know about all of this, we can kiss and rub each other’s pussies while we’re awake. Isn’t that wonderful?”

Katy had judged Sharon correctly. There was no way she could live with the whole world seeing her fucking her own daughter. She would do anything to keep it a secret – including carrying the baby to term, and continuing to lez off every night with her beautiful daughter.

Honestly, Sharon didn’t mind licking her daughter’s cunt, or having Katy suck on her tits. It was surprisingly erotic. But she told herself she was only doing it because Katy was making her.

Katy had other ideas, too – like maybe Sharon didn’t need to wear clothes around the house. And maybe Sharon could give blowjobs to some of Katy’s male friends, in exchange for money. Or fuck them, for even more money. It wasn’t like Sharon could get more pregnant.

But Sharon had her own plans. She had been scared to find a new husband – but if she was going to have another baby, it would need a father, to stop it from growing up into a perverted blackmailing lesbian bitch like Katy. So she started dating.

But she wasn’t just looking for a man for herself. She was looking for a man for Katy. She showed photos of Katy to every man she dated – nude photos. And she asked if he would be willing to slap Katy to discipline her. And spank her.

And rape her.

And impregnate her.

Because if Sharon was going to have another baby, it was only fair that Katy have the same experience.

And she’d always thought Katy could stand to have tits that were a bit bigger, and a belly that was a bit rounder.

Katy would look so pretty with a rape-baby growing in her belly…
