Incest Sex Story: Chapter 9 - 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.

Allison smiled bitterly and slowly closed her eyes.
A tear slid down her cheek and dripped onto the cold floor, creating ripples. How she wished that all this was just a nightmare, and that when she woke up, her family would still be in harmony and happy. But reality is always crueler than dreams. As an incompetent mother, she has lost her daughter’s trust and respect forever. From now on, she can only watch Ella step by step into the abyss, but she can do nothing...
Ding Dong, the evil APP has sent new task instructions.
Allison clicked on the message tremblingly, her pupils shrank instantly, and she almost fainted. Oh my God, this devilish software is simply forcing me to destroy my daughter with my own hands!
“Dear Allison, you have been doing very well recently. As a reward, we have a special task for you. You need to find a way to decorate Ella’s room to make it full of an ambiguous atmosphere, like a love nest for couples. For example, turn on some pink lights and put condoms in the bedside table. Oh, and most importantly, you need to find a reason to let Ella temporarily live in Colin’s room and sleep in the same bed with him for a few days. This shouldn’t be difficult, right? Come on, you are a good mother who loves her children the most~”
Allison collapsed on the bed in despair, tears streaming down her face. This beast! He actually wanted me to push my daughter into the fire pit! How could I ... how could I still have the dignity to be a mother? In order to live a shameful life, I actually had to sacrifice my daughter’s chastity ... But, but, was I really going to watch the family’s scandal being exposed? Was I going to let my daughter bear the infamy and ruin my own reputation?
Allison wiped away her tears and walked into Ella’s bedroom. She felt heartbroken when she saw her daughter’s favorite pink curtains, the carefully arranged dolls, and the dazzling pile of awards on the desk.
“I’m sorry, I’m sorry ... I’m useless and can only watch you become your brother’s plaything ... It’s all my fault, it’s all this incompetent mother’s fault!”
Allison ruthlessly pulled down her daughter’s curtains and replaced them with a bright red satin quilt. She lit a few pink scented candles, moved her daughter’s desk to a corner, and replaced it with a gorgeous dressing table. Then, she somehow found a box of Durex from the drawer and placed it next to the pillow...
Allison felt heartbroken. She held back her tears as she arranged everything, then picked up her phone and sent a message to her daughter.
“My dear, our house is being renovated recently, and we need to repaint the walls of your room. You can temporarily live in your brother’s room for the next few days. You can squeeze in with him and it will be ready soon. By the way, I added some new furniture to your room today, put in some pillows, and laid out a beautiful red quilt. Don’t dislike my aesthetic taste when you come back and see it~”
After sending the message, Allison collapsed on the bed, feeling relieved and letting the tears flow freely.
It was all over, everything was over ... From then on, she could no longer face her daughter. She could only dress her daughter up as a seductive whore, and then send her to her son’s bed, letting him defile and ravage her ... Oh my God, what was the meaning of such a mother and such a family?
Allison slowly closed her bloodshot eyes.
Darkness devoured her consciousness, and boundless despair enveloped her heart. Perhaps, being a mother played by her son and a wife who paid off her husband’s debts was her fate ... She was powerless to change it, and could only close her eyes and fall into the eternal abyss...
In the evening, the brother and sister returned home. Ella pouted and ran into her mother’s bedroom angrily, complaining with a sad face: “Mom, do you know? My brother actually touched me today! When we went out to play, he always secretly touched my waist and deliberately rubbed my breasts! It’s so hateful!”
Seeing her daughter about to cry, Allison felt a pang of pain in her heart.
She should have expected this to happen! She was too naive to think that Colin would be obedient to his sister. Now, wasn’t she the one who pushed her own daughter into the fire pit?
Allison suppressed her heartache, pretended to be relaxed and put her arm around her daughter’s shoulders, comforting her: “Silly girl, brother likes you. Boys will always unconsciously get closer to the girls they like. Besides, you are dressed so beautifully today, like a little princess. If it were your mother, she would want to look at you a few more times~”
“But ... but mom, he is my brother!”
Ella’s eyes widened in surprise and her face turned red.
“How can siblings do such a thing? Isn’t this too abnormal?”
“Silly boy, what’s wrong?”
Allison smiled generously, but her heart felt like it was being cut by a knife.
“You two have a good relationship and are very close to each other, so it’s normal. Besides, it’s popular nowadays, and there are many examples of siblings dating. As long as you like it, mom won’t object~”
“Mom, what nonsense are you talking about!”
Ella stamped her feet in anger, her eyes red as if she was about to cry.
“How could I be with my brother ... we are just siblings! I don’t have that kind of feeling towards my brother at all!”
Allison sighed helplessly, stretched out her hand to tidy up her daughter’s hair, and said earnestly: “Silly girl, you are still young and don’t understand the relationship between men and women. Girls, it is more attractive to be ambiguous with boys appropriately and create a hazy feeling. You and your brother are so close, it’s no big deal to cross the line occasionally. Besides, you are siblings, so you don’t have to worry about breaking up in the future, how great~”
“I don’t want to! I don’t want to develop any ambiguous relationship with my brother!”
Ella stamped her feet angrily, tears welling up in her eyes.
