Incest Sex Story: Chapter 12 - 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.
Caution: This Incest Sex Story contains strong sexual content, including Incest Mother Sister
Colin pretended to be shocked and widened his eyes, then subconsciously took a step back.
“Mom, what are you talking about?! We are mother and son!”
“Like you said before, we are not ordinary mother and son. How can a normal mother and son kiss each other, be naked, and masturbate each other? We have done all these, so what can’t we do...”
Allison said coldly, as if she was talking about someone else.
Colin took a deep breath and shook his head with pretended difficulty.
“Mom, I want you, but I want you to give it to me willingly. Now you are obviously giving it to me reluctantly in order to save your sister. I don’t want to accept it...”
“Don’t you love your mother the most?”
Allison raised her tearful eyes and looked at her son pleadingly.
“Didn’t you just do that to your mother today? Now, mother ... mother is willing to let you do whatever you want ... Don’t you want it?”
Colin’s breathing suddenly became heavy, and he stared at his mother intently.
A small tent gradually formed under his crotch, and his desire was clamoring.
Allison saw her son’s hesitation, and stood up to unbutton his shirt. His snow-white breasts jumped out, and his cherry-red nipples were already erect.
“Come on son ... Mom is yours tonight...”
Allison closed her eyes and let the tears flow freely. She opened her arms in a sacrificial gesture, waiting for her son to violate her.
Colin couldn’t bear it any longer, he pushed his mother down on the bed and kissed her red lips greedily.
Allison trembled as she endured her son’s plunder, numbly spreading her legs and allowing him to impatiently pull down her panties.
When her son’s hot cock pressed against her flower heart, Allison closed her eyes in despair.
I’m sorry, daughter ... Mommy was trying to save you...
The next second, the son rushed in fiercely.
The tearing pain made Allison scream and tears welled up in her eyes.
But soon, the pain turned into a tingling pleasure. She couldn’t help but moan and wrapped her legs around her son’s strong waist.
“Son ... your penis is so big ... you are going to break mommy...”
Allison moaned lasciviously and twisted her waist to match her son’s thrusting.
Colin growled and charged forward even more fiercely.
“Mom, you’re so tight inside ... your son wants to fuck you until you get pregnant...”
The mother and son were entangled in a passionate and passionate intercourse.
Allison was completely lost in the frenzy of lust, forgetting all dignity and ethics.
She just wanted to be penetrated and possessed by her son again and again, letting him vent his lust on her.
After an unknown amount of time, Colin growled and poured his hot semen into his mother’s womb.
Allison cried out and reached her climax just like that.
Afterwards, Allison curled up in her son’s arms in despair, letting her tears flow freely.
She picked up the phone tremblingly and saw the message on the APP: Mission accomplished. Come and pick up your daughter tomorrow. We didn’t touch her at all...
But the price ... is too high...
“Am I still worthy of being Ella’s mother? Do I still have the face to see my husband?”
Allison stared at the ceiling in a trance.
Her son was sleeping soundly beside her, but she couldn’t fall asleep no matter what.
Is all this ... a nightmare ... or a cruel reality...
Everything is finally settled.
When Colin brought the terrified Ella back home, Allison was ready to say her final goodbye.
She wrote the suicide note with trembling hands, and her tears blurred the handwriting.
“I’m sorry, my dear family. Mom failed to protect you and did such a terrible thing. I don’t have the face to live anymore. Please forgive my cowardice and forgive me for leaving without saying goodbye. I love you, I will always love you...”
She put down her pen with sobs, her eyes lingering on this warm home for the last time. Although her husband was irresponsible, he had given her so many years of happiness. Although her daughter was stubborn and willful, she loved her dearly. Her son ... her son had a distorted desire for her, but he was also her own flesh and blood that she had raised with great difficulty.
Allison took a deep breath and picked up the sleeping pills beside her. Just as she was about to swallow them, Colin suddenly rushed in!
“Mom! What are you doing?!”
Colin was horrified and rushed forward to grab the bottle of medicine.
“Let me go ... I don’t deserve to live...”
Allison closed her eyes in despair, tears streaming down her face.
“It was me who ruined this family ... and violated the moral code between mother and son...”
“Stop talking nonsense, Mom!”
Colin hugged his mother’s trembling body tightly and kissed her tears with heartache.
“You are the best mother in the world! You have given so much to this family and you are willing to sacrifice everything to save Ella. Mom, you are my pride!”
