Incest Sex Story: Chapter 4 - 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’s consciousness gradually blurred. Her mind told her that she had to stop all this, but her body instinctively responded to her son’s invasion. Her waist twisted unconsciously, longing for more caresses. She knew that this was not going to work, but she couldn’t resist the desire deep in her heart.
Just when Allison was about to be overwhelmed by the pleasure, there was a sound of a key turning in the door.
She was struck by lightning and suddenly woke up from her desire. She pushed away her son who was still sucking her nipples and hurriedly picked up the clothes on the ground to cover her naked body.
“Mom, I’m back! The school is closed for half a day today ... Hey, why are you dressed like this?”
When her daughter Ella walked into the living room, her eyes widened when she saw her mother’s revealing outfit.
Colin, who was standing by, was calm and composed, as if nothing had happened. He narrowed his eyes and looked at his mother’s flustered appearance with a half-smile. He knew that this woman had been firmly grasped in his hand. No matter how she struggled, she could not escape from his palm in the end.
Allison gathered her clothes guiltily and said calmly, “Oh, Mom accidentally spilled water on my clothes and was just about to change them. Ella, why did you get out of school so early?”
Ella looked at her mother suspiciously, then at her brother who looked innocent: “The school had a power outage this afternoon for maintenance, so the teacher gave us half a day off. Mom, are you okay? Your face is so red, do you have a fever?”
Allison shook her head and forced a smile, “It’s okay, maybe I was too tired from dancing just now. Mom will go change clothes. I’ll make you whatever you want to eat tonight.”
After saying that, she hid in the bedroom as if she was fleeing from disaster.
The moment the door was closed, Allison finally couldn’t hold on any longer and collapsed on the floor crying. She couldn’t believe that she almost committed incest with her son in the living room. If her daughter hadn’t come back in time, the consequences would have been disastrous.
However, what made her even more desperate was that she discovered that deep in her heart she had a secret desire for this kind of immoral intimacy.
Her son’s skilled caress and ardent gaze brought back the youthful vitality to her long-dry body.
She hadn’t tasted a man for a long time, and even her closest husband avoided her. But now, her son’s touch made her feel like a woman.
Allison felt sick at the thought. How could she have such a dirty desire for her son? She was a mother, a goddess who was always holy in her son’s heart, how could she degenerate into a lewd bitch? She wanted to wash off the mark of her son on her body, but the hot touch was engraved on her skin like a brand, and it could not be wiped away.
Allison hugged her naked body in despair, letting the tears flow freely.
She wished she could die right now so that she wouldn’t have to face her daughter’s questioning, the endless demands of that evil APP, and the shameful self deep in her heart.
She was really scared, so scared that she would fall completely and fall into an eternal hell.
Just then, there was a gentle knock on the bedroom door.
Allison was so scared that she trembled all over, thinking that Colin was playing a trick on her again. She hurriedly put on her clothes and asked in a hoarse voice: “Who is it?”
“Mom, it’s me.” It was the voice of my daughter Ella.
She felt relieved and opened the door to let her daughter in.
Ella looked at her mother’s swollen eyes and messy clothes with a worried look on her face, and asked cautiously: “Mom, did something happen to you? Can you tell me about it?”
Looking at her daughter’s clear eyes, Allison felt a lump in her throat and started to cry again.
How she envied her daughter’s carefree girlhood, unlike herself, who was already covered in mud and too ashamed to face the children.
She hugged her daughter tightly, her voice choked with sobs: “Ella, I’m sorry for you. I’m a bad woman and I’ve failed this family...”
Although Ella was young, she guessed something from her mother’s words. She gently patted her mother’s back and comforted her: “Mom, don’t cry. Dad must have made you angry again, right? Don’t worry, no matter what happens, my brother and I will always stand by you. If you have any difficulties, just tell us, we will definitely understand you.”
Hearing her daughter’s comfort, Allison felt warm in her heart and cried even harder. She didn’t deserve such a sensible and obedient child. She was afraid that she would destroy this hard-earned happiness with her own hands. From her daughter’s words, she seemed to realize that Colin usually pretended to be very good in front of his sister and always played the role of a filial and sensible brother. It seems that this son is not only dirty-minded, but also very scheming, knowing how to use his sister to stabilize himself.
Thinking of this, Allison became even more frightened.
She was afraid that Colin would do something bad to her sister. She swore that no matter how much Colin pushed her, she would never let him get his hands on Ella. Even if she had to sacrifice herself, what would it matter? For her daughter, she was willing to do anything!
Thinking of this, Allison made up her mind, wiped her tears and said to her daughter: “It’s okay, Mom was just thinking about your dad and was sad for a while. Go do your homework, dinner will be ready soon.”
Ella seemed to believe it, but she didn’t ask any more questions. She hugged her mother for comfort and went back to her room.
Allison took a deep breath and forced herself to calm down. She had to find a way out of this predicament as soon as possible and not let her family be implicated again. She had to find a way to get money, pay off her gambling debts and get rid of the APP, and also find a way to discipline Colin and make him give up the evil idea of incest.
