Incest Sex Story: Chapter 8 - That night, Allison had a nightmare. She dreamed that she had committed incest with her son and got pregnant and married, and people found out. Everyone called her a slut, a shameless bitch, and a beast... She screamed "No..." When she woke up, she was already in tears.

“Nothing ... Nothing. Mom is just too tired recently...”
“I know how to make you relax.”
Colin’s eyes darkened and he strode up to his mother.
“Lie down and take off your clothes.”
“Don’t ... not now...”
Allison pushed him away in panic, looking at her son with tears in her eyes.
“Your sister is still at home...”
“That’s great, let her see how sexy her good mother is.”
Colin sneered and ripped open his mother’s clothes without saying a word.
“Hurry up, don’t dawdle, or I’ll call my sister over.”
Allison closed her eyes in despair, trembling as she unzipped her pants and exposed her private parts in front of her son. Perhaps this was the only thing she, a negligent mother, could do ... using her own body to exchange for her daughter’s safety...
As usual, she used her nimble little hands to help her son ejaculate, and watched him walk out of his room with satisfaction, only then did she get a moment of peace.
The evil app gave a new instruction: “Allison, I want you to create some ambiguous atmosphere for your son and daughter. How should I put it? It should look like you are bringing them together. You are very smart and know what to do. Come on!”
Under the tyranny of the app, Allison was afraid that the videos would be made public, so she had to endure the humiliation and continue to work for the evil app. She knew that if she wanted to save this broken family and maintain the surface of decency, she could only degenerate step by step and drag her daughter down with her.
Allison felt heartbroken when she thought of this. But what else could she do except push her daughter into the abyss? Colin had already extended his evil claws to Ella, as a mother, how could she just sit there and watch? Instead of letting her daughter fall into the trap unknowingly, why not arrange everything by herself, maybe she could have more control?
Allison gritted her teeth and sent a message to her daughter: “Ella, you must dress up nicely for the weekend trip to the amusement park. Choose some cool clothes, curl your hair into big waves, and put on some light makeup. You must make your brother’s eyes light up~”
After a while, the daughter replied: “Mom ... why do you suddenly want me to dress up? Don’t you usually not allow me to wear revealing clothes?”
Allison’s heart trembled, and she pretended to be calm and replied: “Silly girl, what’s wrong with dressing up occasionally? Girls should dress themselves up beautifully to attract boys’ attention. Although your brother is a relative, he is also a man after all. You have to leave a good impression on him, right?”
After a long while, Ella replied hesitantly: “Okay, Mom, I get it. I will dress up well...”
Allison felt heartbroken when she saw her daughter’s reply.
What was she doing? She actually taught her daughter to seduce her own brother? She was an incompetent mother and a complete lunatic!
But ... maybe it’s better this way. It’s better to let Colin shift his attention to his sister than to continue to bother him.
Allison smiled bitterly and consoled herself. It was just a pity for Ella to be dragged into this dirty vortex ... I hope she won’t resent me as an incompetent mother in the future...
The weekend is here soon.
Allison got up early to dress up her daughter. She gave Ella a fresh and sweet light makeup and curled her hair into soft and flowing waves.
Looking at her daughter’s radiant face in the mirror, Allison was actually a little jealous. She had been abused by her son for so long, how could she be as youthful and beautiful as her daughter?
“Ella, you are so beautiful.”
Allison praised sincerely, her eyes moistened.
“You must have fun today. I’ll feel relieved if your brother is with you.”
“Oh my god, what can happen between me and my brother?”
Ella blushed and scolded.
“We’re just going out for fun...”
“Silly girl, how can there be so much pure friendship between men and women?”
Allison smiled meaningfully and stroked her daughter’s hair.
“You two have such a good relationship, there’s nothing wrong with being closer...”
“Mom, what’s wrong with you today...”
The more Ella listened, the more confused she became, and she looked at her mother suspiciously.
“My brother and I are siblings, how can we...”
“Okay, let’s not talk about this anymore.”
Allison hurriedly interrupted her daughter and handed her a low-cut halter dress.
“Put on this skirt to show off your good figure. And these high heels will make your legs look longer.”
Ella hesitated for a moment, but still did as she was told. After changing into her clothes, she looked very charming, with her curvy figure clearly visible, and the breath of youth blowing across her face.
“My baby daughter has grown into a very pretty girl...”
Allison was heartbroken. She held back her tears and smiled as she pinched her daughter’s cheek.
“Go ahead. You have to be intimate with your brother today, okay?”
After seeing off her gorgeously dressed daughter, Allison stared at the mirror alone.
