Chapter 1

Allison is a teacher. Today, when she turned on her phone, an app called “Human Behavior Observation Experiment” came into view. It was a simple gray interface with only an eye icon as a symbol. She carefully entered her bank card information, selected the identity role of “wife”, and filled in the family member information.

The system showed that she had received 500 points, which could be exchanged for real money at a one-to-one ratio. Just as she was about to carefully check the task content, a new message popped up: “It is detected that your family is in a major debt crisis. The system will open a special task mode for you. The first task: give your son a hug. Reward: 500 points. Do you accept it?”

Allison’s finger hovered above the screen, hesitating. At this moment, the sound of keys turning came from outside the door. She looked up and saw her son walking in with his schoolbag on his back, his eyes thoughtful.

“Mom, I’m back.” Son Colin said softly, glancing casually at the phone in his mother’s hand.

Allison quickly put away her phone and forced a smile: “You’re back. How was work today?”

My heart was in turmoil and I was in a state of panic.

Last night she accidentally opened the app called “Human Observation Experiment”, which listed a series of embarrassing tasks, and each completed task would earn her a considerable amount of points.

Allison refused subconsciously at first, but then she thought, doesn’t the family need this money to make ends meet? But... these tasks are really too outrageous, they even asked her to have sex with her own son!

While she was thinking, Colin had already stopped in front of her and asked with concern: “Mom, you seem absent-minded today, did you encounter any trouble at work?”

Allison was startled and quickly shook her head to deny it: “It’s nothing, Mom is just a little tired recently. By the way, what do you want for dinner? Mom will make it for you.” Then she got up and went to the kitchen.

Colin grabbed his mother’s hand, looked into her eyes and said, “Mom, I know you have paid too much for this family, and you have been hiding from me the fact that you have been paying off Dad’s debts. You always keep everything in your heart and never tell me. But I have grown up, and I don’t want to be a burden that causes you headaches anymore. I want to be your support.”

Warm tears blurred Allison’s eyes, and her son’s words made her nose sore.

Yes, her little boy has really grown up and become sensible. How can she hide it from him anymore? But at this moment, Allison couldn’t bring herself to admit those dirty tasks in front of her son.

“Mom, don’t cry.”

Colin wiped the tears from his mother’s face distressedly, “No matter what happens, I will always support you and protect you. We will definitely get through this, believe me, okay?”

Allison burst into laughter and held her son’s warm and strong hand tightly. She knew that as long as she had this sensible son by her side, no matter how big the difficulties were, she would not be afraid.

“I believe you, son.”

Allison nodded solemnly. “Mom has something to tell you, too. How about we have a long, heart-to-heart talk after dinner?”

Colin smiled knowingly and nodded firmly in agreement.

The mother and son walked into the kitchen hand in hand and prepared dinner closely.

Whatever difficulties they encounter, they will face them together and overcome them together. Because they are each other’s closest relatives and the strongest support. The sunlight shines through the window lattice, onto the figures of the mother and son, shrouding them in a warm and peaceful atmosphere.

If only it were as beautiful as Allison saw it, but she didn’t realize her son had a venomous heart beneath his gentle smile...

The seemingly peaceful and harmonious family with loving mother and filial children is heading towards a bottomless abyss under Colin’s conspiracy.

After dinner, Allison pulled her son to the sofa, tried to calm her inner tension, and slowly said: “Colin, there is something that mom has been hiding from you. It is about our family’s financial situation...”

Colin sat up straight and looked at his mother seriously.

Allison sighed and told the truth: “In fact, our family is already heavily in debt. Not only is your father unemployed, but he also owes a large amount of high-interest loans due to gambling. Over the years, it has been all thanks to mom’s scraping together to barely make ends meet. Mom’s salary is very meager. If this continues, I’m afraid...”

Colin held his mother’s hand and said firmly: “Mom, don’t be afraid. Since Dad is incompetent, I will be the man of this family. Although my career has just started, I will work hard to make a lot of money and let you live a good life.”

Allison was so moved that she burst into tears and hugged her son tightly in her arms.

She stroked Colin’s hair and said hesitantly: “Actually, Mom recently found an opportunity to make money, it’s a mobile phone APP...but the tasks on it are a little...a little weird.”

Colin looked up in confusion: “What app? What task? Let me take a look.”

Allison had no choice but to take out her phone and open the strange APP.

Colin carefully read the items above, his brows furrowed more and more.

“Mom, these tasks are too much! This is basically... basically asking you to sacrifice your chastity!”

Colin pretended to be so angry that he was shaking all over. “How can these people be so shameless! Mom, you must not agree to them!”

Allison stroked her son’s face and smiled bitterly: “But there is no other way. Our family needs the money so badly now.”

Colin grabbed his mother’s shoulders, his eyes reddened: “No! How can you do this? I should be the one to do it! I am a man, I have the responsibility to protect this family!”

Allison was surprised and happy, and quickly shook her head: “Son, how can I feel at ease letting you face those dirty things? I would rather suffer injustice than delay your career and future.”

The mother and son were at a stalemate, neither of them willing to give in.

Finally, Colin gritted his teeth, took the phone from his mother, and decisively pressed the “Accept Task” button.

“Mom, let’s face it together! You can’t treat me like a child. Since we are a family, we should share the joys and sorrows. No matter what we encounter, we are mother and son, and there is nothing we can’t overcome!”

Allison burst into tears and hugged her sensible son tightly. Yes, how could she bear it alone and shut her son out? They are mother and son, blood is thicker than water! From now on, no matter what happens, they will bear it together!

In this way, the mother and son embarked on an unusual journey of “making money”.

What Allison didn’t know was that all of this was planned by the founder of the app.

And this founder is her gentle, sensible and well-loved son.

He carefully designed this scheme just to push his mother into the abyss step by step.

Allison would never have thought that the greatest danger would come from the person closest to her, the flesh and blood she had raised with so much hardship...

It was already past nine o’clock in the evening when Colin got home from work.

As soon as he entered the room, he saw his mother sitting on the sofa, staring at the phone screen in a trance.

Colin sighed softly, put on his slippers, walked over and sat down next to his mother.

“Mom, are you watching that app again? I told you not to force yourself...”

Colin held his mother’s hand with pretended distress.

Allison finally woke up from her dream and hurriedly put her phone into her pocket.

“Oh, I was just taking a look. There’s no need to force myself. By the way, I saved a portion of dinner for you. Go and eat it while it’s hot.” Allison answered vaguely, avoiding her son’s gaze.

Colin shook his head helplessly and said in a deep voice: “Mom, we agreed to face it together. Don’t take everything on yourself. Your son has grown up and can share the burden with you. Let me see, what is the task this time?”

Allison bit her lip, took out her phone, and opened the scary APP interface.

The screen clearly displayed: “The latest task has been released. Kiss your son for ten minutes and you will be rewarded with 10,000 points. Please complete it within 24 hours.”

“What?! French kiss? That’s too much!”

Colin pretended to be surprised, but in fact the cock in his pants was already hard and painful. He couldn’t wait to taste the beautiful teacher mother’s tongue and suck her sweet saliva.

Allison was so ashamed that tears welled up in her eyes.

“Son, I’m sorry... Mom really didn’t mean to force you... But, but the family really needs this money...”

Allison choked up and explained incoherently.

Colin looked at his tormented mother with pity and hugged her in his arms.

Allison’s eyes widened in shock, her heart pounding.

“Mom, stop talking. Since you’ve accepted the task, you must complete it. Believe me, it’s just a kiss, nothing will happen.” Colin comforted.

In her son’s warm embrace, Allison finally couldn’t hold back her emotions and burst into tears.

She threw herself on her son’s broad chest, crying: “I am such a failed mother. I would sell everything for a few filthy bucks... I am so, so sorry for you!”

Colin gently patted his mother’s trembling back and whispered in her ear: “Silly mother, you are the greatest and most selfless mother in the world. You have given so much to this family, how can a son just sit there and watch? Besides, this is an opportunity to make a lot of money. Let’s be patient, and we will have everything after we get through it...”

Allison burst into laughter and touched her son’s face. She never dreamed that her son, whom she had raised with great difficulty, could give her such strong support and comfort at such a time. Yes, as long as they were united, what difficulties could they not overcome?

Thinking of this, she mustered up her courage, closed her eyes, and raised her chin slightly.

Colin lowered his head knowingly and carefully kissed his mother’s soft lips...

At that moment, time seemed to freeze. The mother and son hugged each other tightly, their lips and tongues intertwined, kissing each other inseparably. The air was filled with a faint ambiguous atmosphere that made people blush.

With a “beep”, the phone sent a notification sound indicating that the task was completed.

Chapter 2

Allison shyly pushed her son away and hurriedly tidied her messy clothes.

Colin was panting, his face still flushed. He coughed twice awkwardly and said, “Well, Mom, I’m going to take a shower and eat...” Then he ran away.

Allison sat on the sofa in a daze, her heart beating. The kiss just now was so intense that she almost forgot who they were for a moment. And her son’s reaction made her feel even more ashamed, as if he had touched her butt while kissing her passionately just now... Could it be that he also had improper thoughts about her?

She shook her head violently, trying to get the horrible thought out of her mind.

No, this is impossible! My son must have done this to comfort me. How could he have evil thoughts about his own mother? I am so filthy!

Allison secretly made up her mind that no matter what excessive demands the app made, she would refuse. For the sake of her son and the future of this family, she must stick to the bottom line!

However, she didn’t know that all this was in her son’s calculations. This seemingly sensible and well-behaved son had already set up a trap using the APP, waiting for his mother to fall into the trap step by step. The taboo game between mother and son has just begun...

In the suffocating atmosphere, Allison tremblingly closed the bedroom door.

She leaned against the door helplessly, and collapsed on the ground, tears pouring out like a dam breaking. She covered her mouth tightly to prevent herself from sobbing, for fear that her son Colin would hear it.

The passionate kiss just now seemed to still linger on her lips, and the burning sensation made her feel ashamed.

She couldn’t believe that she actually kissed her own son, and it was such a crazy and shameless French kiss.

She hated this terrible app because it forced her to degenerate step by step and do such unethical things.

But what made her even more desperate was her son’s reaction.

Not only did Colin not show any resistance or discomfort, but he kissed her so passionately, like a long-hungry beast.

His tongue aggressively invaded her mouth, greedily absorbing the sweet saliva, while his hands were still wandering restlessly over her body...

Allison shuddered violently.

Oh my God, could it be that my son really has desires for me? Or has he always had these dirty thoughts but just hid them very well?

Allison shuddered at the memory of her son’s usually overly attentive behavior and fiery eyes.

She found that she could no longer understand her son.

Colin seemed to be wearing a mask. On the surface, he was a sensible and well-behaved son, but in private, he was secretly planning something.

With a “ding ding” sound, the damn APP sent a new task reminder.

Allison opened the interface with shaking hands, and saw the words written on it: “Ms. Allison, the task was completed very well. There will be more exciting tasks in the future. I believe you are looking forward to it, right?”

Allison covered her face in despair.

This perverted APP is simply the devil! Is it deliberately trying to destroy itself?

However, the family still owes a large amount of debt. The husband’s gambling debts and loan sharks have to be repaid, and the daughter’s tuition is also a big burden. Without enough money, this family will really fall apart.

Thinking of this, Allison gritted her teeth. No matter what, she would never let this family fall apart!

She wiped away her tears and forced herself to calm down. For the sake of this family, she had to be strong.

Allison tossed and turned at night and couldn’t fall asleep.

Her son Colin’s reaction made her uneasy. The shame, pain and confusion in her heart were intertwined and almost overwhelmed her. When she thought of Colin’s passionate response to the kiss and his hands wandering on her body during the kiss, she felt sick. Could it be that her son really had improper thoughts about her? This terrible thought made her scalp tingle.

The next morning, Allison had dark circles under her eyes, but she forced herself to go to the kitchen to prepare breakfast.

She deliberately wore a tight and conservative turtleneck sweater, as if this could cover up her inner shame. When she heard Colin’s footsteps coming down the stairs, her whole body froze and she almost dropped the spatula in her hand.

“Morning, Mom.”

Colin walked into the kitchen and greeted with a relaxed look on his face, as if nothing had happened last night.

Allison forced a smile. “Morning, did you sleep well last night?”

“Yeah, I slept really well.”

Colin gave her a meaningful look, a faint smile on his face.

Allison’s heart skipped a beat and her face burned. She didn’t dare to think about the deeper meaning of her son’s words. She just hurriedly served breakfast and lowered her head to eat the porridge in the bowl. The meal was extremely silent and awkward. Both mother and son were worried and just focused on eating.

After finishing his meal, Colin prepared to go to work.

Before leaving, he suddenly turned around and said to his mother with a pure face: “Mom, about that... last night’s incident, I know you must have been very resistant in your heart. I’m sorry, it’s all because of me...”

Allison’s heart suddenly tightened.

She didn’t expect her son to bring up this matter on his own initiative.

Seeing Colin’s guilty and remorseful expression, she suddenly wondered if she had thought too much last night. Her son must have done that to comfort her. How could he have any improper thoughts about his mother? She was so self-indulgent!

Thinking of this, Allison softened.

She walked forward and hugged her son gently: “You are such a sensible child. Mom knows you are trying to help me, how can I blame you? Don’t worry, we can face any difficulties together. It’s just a kiss, it’s no big deal.”

Hearing his mother’s words, Colin’s eyes lit up and a strange smile flashed across his lips. But he quickly restrained himself and hugged his mother back with a touching look: “Mom, thank you for understanding me. I promise that I will help you through this difficult time.”

After sending her son away, Allison slumped down on the sofa exhausted.

She really didn’t want to go to work and claimed she was sick.

The terrible thought last night seemed like a dream. She felt that she was too neurotic. How could she doubt her son’s character when he was so good to her? Maybe it was too much pressure that made her almost collapse.

Ding Dong! A new email popped into Allison’s phone. It was from that damn APP.

Allison opened it with disgust, and saw the following words: “You completed last night’s task very well, and the reward has been received. However, the next task is not so simple. You must let your son touch your whole body. If you can’t do it, you know the consequences. See you tomorrow, my dear Allison~”

Allison covered her face in despair, tears bursting out again.

Oh my god, how far will this devil push me? !

She slumped to the ground, sobbing.

At this moment, the cell phone suddenly rang.

Allison looked closely and saw that it was her husband Evan calling. Wasn’t this gambler hiding out from debt? Why was he calling at this time?

She picked up the phone suspiciously, and Evan started to curse her: “I’m blocked, and I don’t have a penny! Transfer 50,000 yuan to me immediately, or I’ll tell the kids that you’re cheating on me! Believe it or not, I’ll post all your nude photos on the Internet!”

Allison was so angry that she was shaking all over. She was furious: “You are such a heartless person! You have brought this family to this state, and you still have the nerve to ask me to give you money? If you dare to say anything nonsense, I will go to the police station to sue you for defamation!”

Evan sneered: “Do you think I don’t know? How much money can a teacher like you make? You can help me pay so much money, you must have earned it by selling your body, right? If you don’t give it to me, we will both die! We have been married for so many years, I must have your nude photos, right? Do you remember the few intimate videos we recorded when we were in love? If people knew that you were a shameless slut, what would your son and daughter think of you?”

Evan’s words were extremely vicious, and every word pierced the heart.

Allison felt cold all over, and her hands and feet were numb.

She knew that the desperado in front of her was a man of his words. If he really exposed her affairs, the consequences would be disastrous. For the sake of her child, she could not take this risk.

“You beast! I hate you! If it weren’t for the child, I would never give you a penny even if I die!”

Allison cursed at the top of her lungs.

Under the man’s threat, Allison hung up the phone tremblingly.

She leaned against the wall in despair, tears streaming down her face.

The weight of reality was overwhelming her, and coupled with the possible improper thoughts of her son Colin, it was driving her crazy.

Allison took a deep breath and forced herself to calm down. She knew she had no choice. For the sake of her children and this family, she had to bow to the devil. Making money from the APP and completing those shameful tasks seemed to be the only way out. But, how could she let her son touch her all over her body?

Just when Allison was struggling with her conscience, Colin had already returned home.

Seeing his mother’s haggard and pale face, he asked with concern: “Mom, are you okay? You look so pale, are you feeling unwell?”

Allison forced a smile: “It’s okay, just a little tired. By the way, that APP sent a new task, I took a look...” As she said that, she handed the phone to Colin with a blushing face.

Colin took the phone and scanned the screen quickly.

His pupils shrank slightly and a suspicious blush appeared on his cheeks.

He cleared his throat and said seriously, “This request is indeed a bit excessive. Otherwise, why don’t we just not do it? There are always other ways to deal with family matters.”

Hearing her son’s words, Allison shook her head and smiled bitterly, “What can we do? Your dad called again to ask for money, saying that if you don’t give it, he will go to the school to make trouble. If my reputation is ruined, your school and work will be affected. Besides, we still owe a lot of debt. Son, I’m sorry, mom can only let you down.”

Colin held his mother’s hand distressedly: “Mom, don’t say that. I’m willing to do anything for this family. In fact, I don’t feel wronged. I’m glad to help you.” As he spoke, his hand gently stroked his mother’s face, stroking her soft skin with his thumb.

His body stiffened and he subconsciously wanted to dodge, but he forced himself not to move.

She felt a thrill in her son’s warm palm.

She knew that this seemingly sensible child had actually been stirring in his heart for a long time. But she couldn’t push him away because she had no choice.

“Let me see, you want to touch mom all over her body, right? Then I’ll start from the beginning.”

Chapter 3

Colin gently stroked his mother’s black hair, his fingertips lightly brushing across her white neck, causing her to tremble slightly.

Then, his hand slowly moved down, brushing across his mother’s beautifully shaped collarbone, and finally stopped at her full breasts. Through the thin sweater, he felt the soft elasticity of that mass. He couldn’t help but pinch it, and his mother immediately let out a soft gasp.

“S-sorry, Mom. I pushed too hard.”

Colin blushed and let go of her hand, but his eyes clearly showed reluctance.

“No… nothing.”

Allison lowered her head, not daring to look at her son’s fiery gaze. She felt a sharp pain in her chest, as if her son’s handprint was still there. She knew that this small action had ignited her son’s desire.

And I am afraid it will be difficult for me to go back to the way I was before.

“Then I’ll continue.”

With his mother’s tacit consent, Colin’s hands began to wander freely on his mother’s body.

He first traced his mother’s slender waist through her clothes, then reached into her hem and lingered on her flat belly.

Allison bit her lower lip, trying to hold back the moan in her throat.

Her son’s warm palms wantonly ignited her most private parts. This kind of immoral pleasure made her feel extremely ashamed, but also inexplicably excited. She closed her eyes in despair, feeling her son’s hands all the way down, caressing her round and perky buttocks and slender legs.

“Mom, you have a really great figure. It’s a pity to hide such a beautiful curve under clothes.”

Colin exclaimed sincerely, his tone full of obsession.

Allison couldn’t hold it in any longer and choked out, “Enough, stop talking... I’m your mother, you can’t say that...”

Colin chuckled and said, “I know. But mom, don’t you think the relationship between us has deteriorated a long time ago?”

Allison opened her eyes suddenly and looked at her son in horror: “You...what are you talking about?! We are mother and son!”

“But how many mothers in the world would kiss their sons? How many mothers would let their sons touch their bodies at will?”

Colin pointed out sharply, his tone full of pride.

Allison was speechless, as if struck by lightning.

She suddenly realized that what her son said was absolutely right.

In just two days, the relationship between mother and son has become extremely ambiguous.

What’s even more terrifying is that deep down in her heart, she actually had a secret expectation for this forbidden intimacy.

Oh my God, is she still worthy of being a mother?

Allison covered her mouth in despair and looked at her son in disbelief.

“Mom, you don’t know how beautiful you are. I want to be your man so much. I am grateful to this evil app. If it weren’t for it, I wouldn’t have the chance to kiss you...”

Allison felt dizzy at her son’s explicit words.

She couldn’t believe that her relationship with her son had fallen to this point. In just a few days, under the pressure of this terrible app, she broke through her bottom line step by step and did all kinds of unbearable things.

Now, even his son has begun to covet him, who can he blame for all this?

Allison struggled to push Colin away, muttering: “No, this won’t work. I’m your mother, how can we...”

However, before she could finish, Colin hugged her in his arms and blocked her mouth.

The warm lips pressed tightly together, and the flexible tongue went straight in, stirring freely in Allison’s mouth. This kiss was completely different from yesterday, full of aggression and lust, as if he wanted to tear her apart and eat her up.

Allison struggled desperately, but was no match for her son’s brute strength and could only helplessly endure this overbearing kiss.

Colin let go of his mother’s lips and licked the corner of his mouth with satisfaction: “Mom, you know, this is the moment I’ve been dreaming of. Since junior high school, I’ve been fantasizing about your body, tossing and turning day and night. Now, we’ve come to this point, do you still want to deny it?”

Allison’s eyes widened in horror, her heart almost jumping out of her throat.

She could never have imagined that her son had such dirty thoughts towards her, and that it had lasted for so many years.

She simply couldn’t imagine that this seemingly well-behaved child actually had such a face behind the scenes.

However, Allison could not deny that her son’s kiss gave her a secret pleasure.

The feeling of being possessed by someone so forcefully made her whole body numb.

She knew it was wrong, but she couldn’t resist the throbbing in her heart. Oh my God, was she really going to be dragged into the abyss by her son?

Just when Allison was struggling with her conscience, there was a “ding dong” sound, and the evil APP started moving again.

Allison opened the interface tremblingly, and saw a new task written on it: put on sexy lingerie and perform a striptease for her son, and the reward is up to 50,000 points.

Allison gasped, completely stunned.

This APP is really going to kill her! Wearing sexy lingerie is fine, but dancing erotically? Isn’t that something only strippers do? But 50,000 points are enough to pay off her husband’s gambling debts.

Thinking of her ex-husband’s threat, Allison gritted her teeth and made up her mind.

“Son, Mom has a request.”

Allison squeezed out these words from between her teeth, “Can you please go out for a while and let Mommy change her clothes. Later, Mommy has a surprise for you.”

Colin’s eyes lit up when he heard this.

He knew what his mother was going to do, and immediately went out excitedly, closing the door considerately.

Allison felt relieved and slowly dug out the sexy lingerie from the bottom of the closet - it was a cheesy gift given to her ex-husband by her best friend when she was newly married, and it had been hidden in the bottom of the closet until now.

The red lace bra can barely cover her breasts, and the pink thong is faintly visible. Paired with black suspender stockings, she looks seductive and flirtatious.

Allison blushed as she put on the clothes. She realized that she had maintained such a good figure, showing off her curves. She looked younger than her daughter.

Taking a deep breath, Allison tremblingly opened the bedroom door.

I saw Colin sitting upright on the bed, waiting eagerly.

When he saw his mother’s outfit, his jaw dropped.

Allison was so ashamed that she walked up to Colin.

She only knew a little about striptease and learned a few basic moves by following the tutorials on the APP.

She first twisted her waist slowly, letting her plump buttocks sway in front of Colin’s eyes.

Then, she leaned against her son and slowly squatted down, her thighs spread in an M shape, revealing her beauty. Colin stared with his eyes wide open, his Adam’s apple rolling violently.

Seeing her son so obsessed, Allison knew that she was doing a good job. She began to get better and better, and her movements became more and more bold. She rubbed her chest against her son’s chest, and her red bean was faintly visible; she bent her legs and grabbed the back of her foot with her backhand, showing her amazing flexibility; she supported herself with both hands and hung upside down, with a clear view of the black forest.

Colin couldn’t sit still any longer, he stood up and rushed to his mother in two or three steps.

He hugged his mother and groped her body with his hands.

He kneaded his mother’s breasts, and could feel the elasticity of the soft flesh through the lace underwear; he stroked his mother’s hips, and could feel the heat there through the thong. He couldn’t wait to possess this mature and attractive woman in front of him, and he didn’t care about his ethics.

Allison was at a loss for words because of her son’s sudden enthusiasm. She tried to push Colin away, but he held her tighter. Colin’s hands wandered wantonly on his mother’s body. Through the thin lace underwear, he kneaded Allison’s breasts wantonly, and with his other hand he held Allison’s hips and rubbed them hard.

Allison was mortified. She had never thought that one day she would be dressed so revealingly and pose in front of her son.

“Mom, you know, I’ve been waiting for this day.”

Colin whispered in Allison’s ear, his hot breath hitting her sensitive earlobe and causing her to tingle.

“I’ve been fantasizing about your body for a long time. Now I finally have the chance to taste your deliciousness, and I won’t let it go easily.”

Allison shuddered, she couldn’t believe her own son would say such obscene words. But what made her even more desperate was that her son’s touch actually gave her a secret pleasure. The pair of big hands with thin calluses lit a fire on her body, and she could feel the burning heat through the fabric.

Allison clenched her teeth, trying hard to resist the urge to moan.

“No, Colin, stop it! Mommy can’t do this to you!”

Allison struggled with all her might, she was afraid that once she crossed this line, there would be no going back.

“Why not? The app lets you dress like this to seduce me, isn’t it just so I can possess you?”

Colin smiled flirtatiously and ripped off Allison’s bra.

The full breasts bounce out, and the pink nipples have already stood up quietly.

Colin took the tempting red tassel in his mouth and sucked it greedily. At the same time, his hands were not idle, sliding along his mother’s slender waist and into her thong.

“Ah! No!”

Allison screamed as she felt her son’s hot hand touching her most private parts.

Colin’s long fingers teased her labia, which was soon covered in slippery love juice.

“Mom, you’re already so wet, and you’re still saying no? You’re obviously enjoying it too.”

Colin increased the strength of his hands with a wicked smile. His middle finger pushed open the slit and slowly inserted into his mother’s tight vagina.

“Hmm...”

Allison couldn’t hold it in any longer and moaned.

She had never imagined that her body would react so strongly to her son’s caress.

Shame, guilt, and pleasure intertwined together, almost driving her crazy.

Seeing this, Colin took advantage of the situation and added another finger. He imitated the action of sexual intercourse and started thrusting in and out of his mother’s vagina. The rough tip of his finger rubbed against the sensitive inner wall, bringing waves of tingling pleasure.

Chapter 4

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.

Allison locked the door, turned on the computer and logged into a secret forum. This was a forum she accidentally discovered, a platform for exchanging ideas on how to fight against perverted apps. She quickly typed on the keyboard, asking netizens for help about her experience. Soon, many people offered various suggestions, such as calling the police, recording evidence, and pretending to cooperate.

Allison gradually came up with an idea after watching the few words on the screen. She thanked the netizens one by one, exited the forum and cleared her browsing history.

Allison put on a neat business suit and fixed her appearance in front of the mirror. For a long time, she stared at her haggard and resolute self in the mirror and said softly: “Allison, you must remember that you are the mistress of this family, you are the mother, you must be strong!”

All evil started with that damn app. My momentary greed brought me to this situation today. Uninstalling this abominable app is the most important thing I need to do now.

She thought that as long as she uninstalled the evil app, she could return to her normal life. With trembling fingers, she clicked the uninstall button, as if a heavy burden had been lifted off her shoulders.

However, at this moment, the phone suddenly rang with a message alert.

Allison’s heart tightened and she opened the new message in horror.

It was written on the screen: “Dear Allison, do you think you can escape punishment by uninstalling the app? Everything you did before has been recorded and archived by us. If you dare to delete the app in violation of the rules, all the unbearable videos will be made public! As a punishment, we require you to accept a new task. Tomorrow morning, you must wear sexy lingerie and masturbate in front of Colin. Remember, you must let him see you climax! Otherwise, you will bear the consequences!”

Allison felt dizzy and collapsed on the bed. She couldn’t believe that the courage she had mustered up was defeated so mercilessly. If those shameful videos were leaked, her life would be completely ruined. But... how could she let her son watch her masturbate?

Tears flowed uncontrollably, and Allison covered her face in despair. Why, why did God play such a trick on her? What did she do wrong to deserve such punishment? She was just an ordinary housewife who just wanted to live an ordinary and stable life, so why did fate push her into an abyss of no return?

“Ding Dong”, another new message came.

Allison suppressed her fear and clicked it, only to see the words: “Oh, I forgot to tell you, you have to face the camera when you masturbate. Because we need to monitor in real time whether you have completed the task seriously. Remember, at 8 o’clock, you must start the performance on time!”

As if she had been sentenced to death, she could no longer hold on and collapsed on the bed, crying. For the sake of her children and her family, she had no choice but to submit and let others manipulate her. Even though she was extremely reluctant, she had no choice but to bite the bullet and step into this perverted game step by step.

After a sleepless night, Allison got up at dawn with red eyes and washed up. When she looked in the mirror, she was shocked by her haggard face. Two dark circles under her eyes, pale face, completely lost her former spirit. She smiled bitterly, this face was more suitable for what she was going to do next.

Allison mechanically put on the sexy lingerie that made her feel ashamed, and tremblingly set up her phone. The alarm clock rang at 8 o’clock on time, she took a deep breath, and tremblingly pressed the record button.

Facing her son’s surprised and greedy eyes, Allison leaned against the head of the bed, opened her legs and began to soothe herself. She first rubbed her clitoris through her panties, and soon it became wet. Then she reached into her panties and inserted two fingers into her vagina.

“Mmmmm...” Allison couldn’t help but moan. She hadn’t masturbated for a long time.

Being stared at by her son’s burning gaze, she felt both ashamed and excited. Her fingers moved in and out quickly, making a gurgling sound. Her other hand was not idle either, kneading her breasts through her bra.

Colin stared at his mother’s movements intently, wishing he could rush over and do it for her. His crotch was bulging, and his breathing was getting heavier. He stared at his mother’s face, wanting to engrave her confused and fascinated expression in his mind forever.

“Ahhh... I’m going to climax...”

Allison sped up her movements and could feel her pussy spasming. Under her son’s fierce gaze, she screamed and reached her climax. Transparent love juice gushed out, soaking her panties and the sheets.

She collapsed on the bed powerlessly, the afterglow of the orgasm still reverberating in her body. Shame, humiliation, fear, all kinds of emotions intertwined together, making her want to find a hole to crawl into. She didn’t dare to look at her son’s expression, for fear of seeing the disgusting desire on his face.

“Mom, you are so beautiful.” Colin suddenly spoke, his voice low and hoarse, full of lust. “I have waited too long for this day...”

Allison suddenly raised her head and looked at her son with tears in her eyes. She wanted to say something, but was stunned by Colin’s next move. She saw her son “swish” unzip his pants, took out his swollen purple-red penis, and started to masturbate wildly in front of his mother...

Allison was terrified and wanted to stop him but couldn’t move. She could only watch her son ejaculate on her, the hot semen sprayed on her naked body. At that moment, something changed forever, and the relationship between mother and son could never go back...

Chapter 5

In front of the camera, Allison was crying as she struggled to recite the lines sent by the scary APP: “Mission... accomplished... I will always... obey you... please... please don’t hurt my family...” Before she finished her words, she could no longer hold on and fainted.

That terrible app is like a leech that won’t go away.

It had only been one day since she had masturbated in front of her son, but this day had felt so long to her, as if it had been a century.

Just as she was still immersed in shame, the terrible reminder sound rang again.

Trying her best to suppress the grief and despair in her heart, Allison tremblingly picked up her phone and clicked on the evil APP interface. As expected, a new task notification had been waiting for a long time, like a sword of Damocles hanging over her head.

Allison bit her lip and clicked the message with tears in her eyes.

The APP’s reward mechanism and the next task come into view:

“Dear Allison, congratulations on completing another test! As a reward, we have deposited 50,000 yuan into your account. But this is just the beginning. If you want to get rid of us completely, you need more points. Let’s take a look at your next task: Tomorrow when your son gets home from get off work, you have to try to swallow his semen without leaving a drop! Remember, you can only use your mouth and hands. We will monitor the whole process, and you will lose points if you do not do well!”

Allison’s eyes went dark and she almost fainted. She covered her mouth with trembling hands, unable to believe that there was such a perverted and vicious request in the world. She was asked to swallow her own son’s semen. Was he asking her to perform a pornographic skit in public? This was a hundred times more humiliating than being raped by her son. It was simply naked humiliation!

Allison collapsed on the bed in despair, tears streaming down her face. For this family, she had already sacrificed all her dignity and sold her body. But this devilish app was not satisfied and wanted to ravage her personality and soul as well! She wished she could die right now, so that she wouldn’t have to face the questioning of her son and daughter, the endless demands of the evil app, and the shameful self deep in her heart.

She turned over weakly, and then she found a note under her pillow. She unfolded it tremblingly, and saw that it was written in a flamboyant style: “Dear mother, I know you don’t want to do all this, but no matter what, mother, I don’t want to hurt you, I love you!”

The note fell to the ground and Allison closed her eyes in despair.

She had no choice but to continue along this path of no return, falling step by step into the abyss of hell from which there was no escape.

In the endless darkness, Allison gradually fell into a coma, but nightmares followed one after another. She dreamed that she was kneeling under her son’s crotch like a bitch, licking his purple-black big cock uncontrollably with her tongue. Colin grabbed her hair hard, pressed her head to his crotch, and thrust deep into her throat.

“Eat it, Mom. Eat it all. Don’t leave a drop!” Colin roared, and his waist moved back and forth wildly, forcing the strong masculine scent into his mother’s body.

Allison coughed violently, tears and saliva all over her face, like a bitch being abused by her master. Finally, Colin growled, and thick and smelly semen gushed out, choking her and almost suffocating her.

“No... stop...”

Allison shook her head desperately, trying to escape from her son’s grasp, but Colin laughed and held his mother’s head tightly, forcing her to swallow what was in her mouth.

Allison closed her eyes in pain and was forced to swallow, saliva flowing freely from the corners of her mouth.

“Good mother, you really know how to suck!”

Colin played with his mother’s powerless body wantonly, like a prostitute.

“Let your mother drink her son’s semen every day from now on. I guarantee that you will become more and more charming, and your pussy will be fucked into the shape of this cock by your son!”

Finally, Allison woke up from the nightmare, crying. Cold sweat soaked her vest, and her body was cold and sticky. She trembled and touched her lower body, and found that her underwear was soaked.

Unable to tell whether it was sweat or vaginal fluid, Allison bit her lip in shame. Even in her dream, her body instinctively felt a shameful pleasure from her son’s rough treatment.

Just then, there was a gentle knock on the bedroom door.

Allison shuddered and pulled the quilt over herself reflexively. She only heard Colin’s deep voice outside the door: “Mom, I heard you were having a nightmare. Are you okay? Can I come in and see you?”

Allison curled up stiffly in the bed, feeling like a lamb to be slaughtered. She knew her son was outside, waiting to see her and would rush in and eat her up at any time. But what else could she do except to accept it?

“Mom...Mom is fine.”

Allison choked up and answered, trying not to let her voice reveal her fear. “Go to bed quickly, you still have to go to work tomorrow. Mommy...Mommy will complete the task well...”

Colin whispered outside the door: “Okay, Mom, go to bed early. I love you...”

A sleepless night.

Allison got up from the bed at dawn. Her face was as pale as paper, with two big dark circles under her eyes. She washed herself mechanically, stared blankly at her haggard self in the mirror, and a bitter smile appeared at the corner of her mouth. Allison, who was once full of vigor and vitality, now had to seduce her own son and swallow his semen. What could she do about it?

Allison trembled as she opened the closet and pulled out a set of sexy lingerie. A translucent lace bra, a low-cut, backless suspender nightgown, and crotchless thong panties. She closed her eyes and put on this unsightly outfit, feeling like a call girl about to receive a customer. She suppressed her shame and examined herself in the dressing mirror.

The two breasts on her chest were full and straight, almost bursting the fragile lace. The snow-white breasts overflowed from the edge of the cup, and the deep cleavage was even more obvious. The slender legs stretched out from the hem of the nightgown, and the skin was shining seductively in the morning light. The hidden triangle area was looming, exuding the breath of a mature woman.

“Mom, is breakfast ready? I’m hungry.”

Her son’s voice came from outside the door. Allison was startled and almost stumbled in panic. She calmed herself down, tightened the belt of her nightgown, took a deep breath, and opened the bedroom door.

Colin was sitting at the dining table playing with his cell phone. He immediately looked up when he saw his mother come out.

The mother walked towards him, her pajamas hanging loosely on her shoulders, her breasts vaguely visible. She bent down to serve her son some porridge, and her full breasts slipped from her collar and almost popped out.

“Mom, why are you dressed like this today?” Colin’s eyes were immediately fixed on his mother’s chest. He felt his lower body quickly engorged with blood and erection, and he wanted to rush up and kill his mother right there.

“Nothing... nothing. It’s hot, dress coolly.”

Allison explained in a panic, her pretty face flushed. She glanced at her son’s bulging crotch with her peripheral vision, lowered her head in shame, and quickened the speed of serving the dishes.

Allison felt hot all over because of her son’s burning gaze. She felt her private parts getting wet, and her panties were soaked with honey. She knew that this was the “seduction” required by the app, and the humiliation and sense of guilt made her want to vomit. But for the sake of her family, she had to bite the bullet and continue the performance.

“Son, eat quickly.”

Allison sat down next to her son and deliberately pulled him into her arms.

“When you go to work later, give me a ride to the mall to buy some things, and we can have a good chat on the way.”

Her thighs inadvertently pressed against her son’s legs, and her soft breasts brushed against his arms.

Colin suddenly felt dry in the mouth and couldn’t even swallow the porridge. He nodded stiffly, unable to take his eyes off his mother.

The mother and son spent their breakfast in awkwardness and heat.

Allison was cleaning up the dishes while observing her son from behind. He had a solemn face and red eyes, looking like a hungry wolf pouncing on its prey. His hands were always on his crotch, as if he was trying to hide something.

Allison couldn’t help but smile bitterly. Was it because she was too charming, or was it because her son had too little self-control? She had finally lowered herself to seduce him, but she didn’t expect that he would take the bait so easily.

Allison closed her eyes in despair, and the drunken joke came to her mind again - if only she could use her body to pay off her husband’s gambling debts. But now things have gone against her wishes. Not only does she have to sell her body, but she also has to become her son’s sperm basin. She really wants to die immediately, so that she can be freed from this hell on earth.

“Mom, are you feeling unwell?”

Colin asked with pretended concern, but his eyes were fixed on his mother’s chest.

“I see you don’t look well, why don’t you just rest at home today?”

Allison forced a smile, stood up and said, “It’s okay, let’s go.”

She turned and walked towards the bedroom, her white thighs and buttocks exposed from the hem of her nightgown.

Colin’s eyes were wide open and his lower body was so hard it was about to explode.

The more he thought about it, the more he felt pain in his lower abdomen, and he urgently needed to vent.

So Colin took advantage of his mother changing clothes and slipped into the bathroom. He took out his painfully hard cock and started jerking it wildly towards his mother’s seductive appearance in his imagination.

Allison heard her son’s suppressed breathing coming from the bathroom, and she thought to herself, this little bastard, is he really going to masturbate in front of her?! She stood there in a trance, her mind was torn between her conscience and her conscience. Her mind told her that she should leave, but her subconscious mind urged her to stay. The threat of the APP and Colin’s peeping were all pushing her into an abyss of no return.

Allison walked to the bathroom door as if possessed by a ghost, and pushed it open a crack with trembling hands. The scene she saw made her body stiffen and she had difficulty breathing. She saw Colin with his back to the door, holding a thick penis in his hand, and stroking it quickly. He closed his eyes, muttered something in his mouth, and kept thrusting his waist.

Allison listened carefully and found that it was actually calling her name!

“Ah...Mom...It feels so good...Mom’s tits...My big cock will fuck you to death...”

Colin was talking in a daze, completely immersed in the fantasy of having sex with his mother. The room was filled with the sound of masturbation and sticky panting.

Allison’s legs went weak and she nearly fell. She covered her mouth tightly, afraid to make any sound. Her heart was in turmoil, ashamed and angry. But she couldn’t take her eyes off her son. The boy’s strong and powerful body, the purple and black thick penis, the blue veins that popped up when he stroked it, and even the prostate fluid oozing out of the urethra, all stimulated her nerves.

She felt a hot current rushing to her lower abdomen, and her vagina contracted involuntarily. Shame, guilt, excitement, fear, and all kinds of contradictory and complex emotions intertwined together, making her almost collapse. She wanted to escape from this place of trouble, but she also wanted to stay and witness her son’s ugly behavior.

After an unknown amount of time, Colin suddenly opened his eyes and stared at the crack in the door with red eyes.

Allison was so frightened that she stepped back hastily. But it was too late. She clearly saw a cruel smile on her son’s face.

“Mom, have you been watching me masturbate for a long time?” Colin’s voice was low and hoarse, full of oppression. “Come in, I’ll show you carefully.”

Allison felt as if she had fallen into an ice cellar. She stiffly opened the door and walked in.

She tried hard to hold back her tears and humiliation, and said calmly, “Son, what are you doing? Put on your clothes and go out with your mother...”

“Where to?”

Colin smiled slightly, but did not stop stroking his penis.

“Mom, don’t you know the mission of the APP? I looked at your phone and the app requires me to ejaculate in front of you and you to swallow all the semen without leaving a drop. You accepted this voluntarily!”

Chapter 6

Allison turned pale and was speechless.

She never expected that Colin actually knew the new requirements of the APP!

For a moment, her mind went blank and she even forgot to breathe.

Colin did not give his mother a chance to speak and quickened his movements. He stared at his mother with a sharp gaze, as if he wanted to see through her soul. His mother’s beautiful and charming figure, half-covered breasts, and slender white legs aroused the most primitive animal desire in his heart.

“Mom, I want to cum on your face, in your mouth, and taint you all over...” Colin said obscenely, his breathing getting heavier. “I want you to get pregnant with my child, and I’ll fuck you for the rest of your life, and you’ll never be able to leave me...”

Allison’s eyes went dark and her body shook uncontrollably. She closed her eyes in despair, tears as big as beans kept rolling down her cheeks. Why, why? What did she do wrong to deserve such inhuman humiliation? Her son had become a monster, her husband had become a waste, her daughter was still in school, she was helpless, who could she count on to save her?

“Ah... I’m cumming! Eat it all!”

Colin roared, and his thick semen gushed out, all of which shot onto Allison’s face. The mother’s horrified expression became the best catalyst for her son to reach orgasm.

Allison’s mouth twitched and she wanted to vomit, but Colin didn’t give her any reason and slapped her mother’s cheek with his big cock covered with sperm.

“Eat it, don’t leave a single drop, or I’ll upload the video to the Internet immediately!”

Allison completely collapsed. She trembled and stuck out her tongue, crying as she licked the thick semen her son shot on her face. The fishy smell filled her mouth and nose, making her want to gag. She swallowed the last mouthful and felt the world spinning. Shame, anger, fear, helplessness, all the emotions burst out at this moment.

She could no longer hold on and fell headfirst onto the cold tiles, falling into a coma. Before she lost consciousness, she vaguely heard her son whisper in her ear: “Good boy, Mom, I love you so much...”

The darkness devoured Allison’s consciousness and dragged her into the endless abyss of hell. But she knew that the nightmare had just begun.

Allison opened her eyes and felt dizzy and weak. She looked around blankly and found herself lying on the sofa in her living room. Colin sat beside her with a worried look on his face, holding her hand tightly.

“Mom, you finally woke up!” Colin shouted excitedly, his eyes slightly red, as if he had just cried. “I’m sorry, it’s all my fault, I shouldn’t... do that to you.”

Allison felt so ashamed that she couldn’t even look her son in the eye. Colin had just forced her to swallow his semen, and she actually did it! She couldn’t help but feel sick when she thought of the fishy smell and sticky texture. But what did Colin say? Was he apologizing?

Seeing his mother’s complicated expression, Colin quickly explained: “Mom, I know I was wrong. I shouldn’t have insulted you in such a vulgar way. But I really love you! It’s not the love of a son for his mother, but the love of a man for a woman. Since I was very young, I have only loved you...”

Allison’s head buzzed, and she felt like she was struck by lightning. She opened her mouth and wanted to scold her son, but something seemed to be stuck in her throat and no sound came out.

Colin looked at his mother’s pale face and trembling lips, a hint of triumphant smile flashed across his eyes, then he concealed it into a sad expression.

He held Allison’s hands tightly and said earnestly: “Mom, I confessed to you a long time ago. I thought I would always have a crush on you, but the appearance of that app made me unable to hide my feelings anymore. Every day when I see you walking around the house, I can’t wait to pounce on you and take you...Mom, just obey me! I will treat you well and never let you suffer any grievances again.”

Allison trembled all over, her mind went blank. Her son had a forbidden desire for his mother, and even wanted to possess her... How could this be possible?! She let Colin hold her and kiss her cheeks and neck. Her son’s hot lips and burning breath reminded Allison that all this was real.

She was not dreaming, her son really turned into a hungry wolf, coveting his mother’s body!

“No...No...” Allison finally regained some of her sanity and weakly pushed her son away.

“Colin, are you crazy? I’m your mother! How can you have such thoughts about me? This is incest! It’s a crime!”

“Oh, Mom, aren’t you enjoying it too?”

Colin sneered and ripped open his mother’s shirt, revealing the sexy black lace bra underneath.

“You are dressed so provocatively, aren’t you trying to seduce me? Do you want your own son to fuck you hard? Since you feel the same way, let’s stop pretending and go to bed and have a three hundred round battle!”

Allison was so ashamed and angry that she burst into tears. She collapsed on the sofa helplessly and let her son do whatever he wanted. Yes, isn’t she a slut? Otherwise, how could she dream of being raped by her son and still be aroused? How could she follow the instructions of the APP and wear sexy lingerie to seduce her son? She had already fallen a long time ago, how could she still have the face to be a loving mother and a good wife?

“I’m sorry, Mom, I was so impatient.”

Seeing his mother’s desperate face, Colin suddenly stopped being tough, hugged her gently and comforted her. “I shouldn’t force you. After all, you are not ready to accept mother-son incest. But mom, I really love you and want to stay with you forever. Can you give me a chance? I swear to love you and never marry another woman in this life. Mom, please don’t reject me...”

Allison closed her eyes in despair and let the tears flow freely.

Her life was ruined by an evil APP. Her husband is a gambler, her son is a sex maniac, her daughter is still young, and her family is burdened with huge debts. What else can she expect? What else can she ask for? Perhaps, obeying her son and repaying the gambling debt with her body is also a good choice? At least... she can keep this family and watch her daughter grow up safely...

Allison felt hopeless when she thought of this and stopped struggling. She nodded woodenly and said softly, “Okay, Mom... I promise you. Let’s... give it a try. But you have to swear not to hurt this family and not to implicate Ella...”

Colin was overjoyed, hugged his mother’s soft body tightly, and kissed her red lips repeatedly.

Great, mom! I know you love me the most! Don’t worry, I will take good care of this family. From now on, you are my woman!”

Allison smiled bitterly, thinking sadly, who else can I be? Maybe sooner or later I will be yours, this is God’s will... She desperately endured her son’s passionate kiss, feeling his big hands wandering freely on her body. Whether it’s the soul or the body, give it all to Colin. Perhaps, this is the last way for her, a negligent mother, to redeem herself!

Allison thought she was hopeless, sinking into the quagmire of forced incest. But when Colin gently held her in his arms and confessed his love sincerely, the last ray of hope in Allison’s heart was rekindled. Perhaps, even if they are mother and son, as long as they love each other, it is not a bad thing...

“Mom promises you...” Allison leaned against her son’s broad chest, closed her eyes and said weakly. “Since you love me so much, then mom will... let you satisfy your craving. From now on, you can come to me anytime you need... But, can you agree to one condition?”

Colin was ecstatic and nodded repeatedly, “As long as mom is willing to be with me, I will agree to anything!”

“Mom can promise you to try to love you as a woman, but Mom can’t accept insertion now...insertion-style sex. Mom needs a little time...During this time, if you need it, Mom can help you with her hands...”

Allison looked at her son with a pleading look, tears in her eyes, and I felt pity for her.

Although Colin was not very willing, this was the biggest sacrifice his mother could make at the moment. He knew he couldn’t push her too hard, so he nodded with difficulty and said, “It’s good enough that mom can help me with her hands, but mom, can you not let me wait too long?”

Allison lowered her head and pondered for a moment, then nodded and said, “Don’t let anyone know...”

“That’s great, Mom!”

Colin hugged his mother excitedly and acted like a child.

“Mom loves me the most. I promise that I won’t let anyone know about our relationship. Let’s just be intimate at home secretly and pretend to be a proper mother and son in front of outsiders, okay?”

“Um...”

Allison nodded in despair, feeling nauseous. She secretly planned in her heart that when she saved enough money, she would take her daughter away and escape from this place of trouble. But for now, she could only swallow her anger and deal with her son, this impatient wolf.

“Mom, I can’t help it...”

Colin panted in frustration and reached out to pull his mother’s skirt.

“I want to watch you masturbate, just like before. Please, Mom, let me enjoy it again...”

Allison froze, overwhelmed with shame.

She pushed her son’s hand away with trembling hands and whispered, “Don’t...don’t do it here...go...go to the bedroom.”

Mother and son stumbled into Allison’s bedroom.

Colin couldn’t wait to push his mother down on the bed and hurriedly took off her clothes.

Allison closed her eyes and let her son undress. He was her son anyway, so why should she be shy? She smiled bitterly, took off all her clothes, and lay naked in front of her son, looking at him resentfully.

“Mother...”

Colin’s lustful eyes swept over his mother’s mature and attractive body, and wherever his eyes went, there was naked spring scenery.

“Your figure is amazing, sexier than any female star! Come on, let me admire it...”

Allison suppressed her shame and slowly opened her legs, completely exposing her private parts to her son.

The pussy was still wet from the stimulation just now, and the pink labia were slightly open, revealing the bright red tender flesh inside.

Colin’s Adam’s apple rolled and he stared at his mother’s lower body with red eyes.

“Mom, touch it...”

Colin said hoarsely, pulling his mother’s hand and pressing it against his crotch.

Allison shuddered in shock as she touched a hot, hard giant object.

Oh my God, when did her son’s thing grow so big? She was possessed by some strange force and touched the thick and long penis through his pants, feeling its pulsation.

Colin gasped in pleasure and reached out to squeeze his mother’s soft breasts.

“Yes, that’s it...Mom, help me take off my pants...”

Allison hesitated, but did as she was told.

As his pants were taken off, Colin’s penis popped out, scaring his mother.

Chapter 7

Colin’s muscular lower body was fully exposed, with his thick purple-black penis sticking straight up between his legs, exuding a strong masculine scent.

Allison looked at her son’s unusually large penis in disbelief, and thought to herself, “Is this... is this really a human thing? How can it be... so big...”

Although I saw my son masturbating in the bathroom last time and he ejaculated on my face, I didn’t really look at his penis because I was shy at that time. Now when I looked at it carefully, I felt my face flushed and my breathing quickened.

“His father’s penis...is probably not even half as big as his...”

As if he could see through his mother’s thoughts, Colin asked proudly, “Mom, is it big?”

Allison blushed and lowered her head, her eyes evading, and whispered: “Don’t say that...”

“Mom, hold it...”

Allison breathed rapidly, and subconsciously grasped her son’s cock, jerking it up and down awkwardly.

“Ah...Mom...”

Colin sighed with pleasure and thrust his hips into his mother’s hands.

“Yes... that’s it... use a little more force...”

Allison blushed and quickened her movements. Fortunately, she had a lot of sexual experience and her hands were becoming more and more skilled.

Her slender fingers flexibly stimulated her son’s sensitive glans and coronal sulcus, as gently and considerately as if she were treating a lover.

Colin soon couldn’t stand this kind of stimulation anymore, and his breathing became heavier and heavier.

“Mom...I’m about to cum...”

Colin said through gritted teeth, his eyes blurry.

“I’m going to cum on your face, don’t hide...”

Allison froze when she heard that, her eyes widened in horror. She couldn’t accept her son’s semen staining her face, it was too humiliating! She subconsciously wanted to let go and run away, but when she remembered APP’s threat, she had to endure the humiliation and kneel motionlessly under her son’s crotch.

“Ahh… cum!”

Colin roared and thrust his waist forward. A large stream of thick semen spurted out and all of it was shot onto his mother’s fair and delicate face. The milky white turbid liquid covered her eyelashes, nose tip and cherry lips, which was extremely obscene.

Allison was filled with shame and anger, and she resisted the urge to vomit. She trembled as she took out her handkerchief and wiped the dirt off her face. At this moment, she felt extremely humble and unbearable, as if her soul had been tainted by her son’s semen.

“Mom, you’re so great... so comfortable...”

Colin hugged his mother contentedly and kissed her lips.

“Mom, from now on, whenever I want something, you have to help me...”

Once the floodgates of reason are relaxed, desires will gush out like a flood breaking through a dam.

Under Colin’s persistent request, Allison has gradually gotten used to helping her son relieve his desire every day. Although she is still extremely ashamed, at least Colin promised not to really violate her, which comforts her a little.

Allison is willing to sacrifice her own dignity as long as she can keep this broken home.

This morning, Allison just woke up from her sleep and felt a hot and hard object against her thigh. She opened her sleepy eyes and found that Colin had gotten into the bed and was holding her legs and rubbing them hard.

“Mom, I want it again...”

Colin was full of energy and was aroused as soon as he woke up. He pulled off his pajamas impatiently, revealing his long and thick cock sticking up high between his legs, and looked at his mother eagerly.

Allison looked at her son’s ferocious penis with bulging veins and swallowed subconsciously. Over the past week, she had already known this weapon like the back of her hand. She had served it tirelessly every day, which made her develop an inexplicable dependence on the male sexual organ.

“Got it...Mom will help you get it out right away.”

Allison murmured, holding her son’s penis skillfully and stroking it up and down. Her soft hands seemed to have magic, flexibly stimulating the glans and coronal sulcus, bringing Colin endless pleasure.

“Mmm...Mom, you are really good at handwork...”

Colin panted comfortably and thrust his hips into his mother’s hand.

“Yes, faster... use more force... baby mommy...”

Allison obediently speeded up her movements, kneading her son’s testicles skillfully. Her slender white fingers were set off by the purple and thick penis, making them look even more slender and tender, presenting a kind of sad and beautiful feeling. She blushed and stared at the weapon in her hand intently, as if studying a work of art.

“Mom, look at me...”

Colin was unhappy with his mother’s distraction, so he turned her chin and made her look directly at him.

“You must serve me wholeheartedly and not be distracted.”

Allison lowered her eyes in shame, not daring to look her son in the face, and could only work harder to appease his desires. She sometimes rubbed the full testicles, sometimes rubbed the sensitive perineum, and even did not spare Colin’s favorite coronal sulcus, which was even more considerate than a lover.

“Hiss...Mom...I’m going to cum...”

Colin suddenly grabbed his mother’s hand and aimed his cock at her fair face.

“Open your mouth...I want to cum in your mouth...”

Allison’s eyes widened in horror, and she subconsciously shrank back, but Colin held her head tightly, forcing her to open her small mouth and aim it at his throbbing glans.

“No...son...don’t...”

Allison shook her head in despair, tears blurring her vision. But Colin turned a deaf ear to her and thrust his hips forward, shooting all of his hot sperm into his mother’s mouth.

“Mmmm...Mmm...”

Allison was choked and coughed repeatedly, her mouth full of the smelly taste of her son’s semen. She wanted to vomit, but Colin pinched her chin and forced her to swallow the thick semen.

“Be good, Mom, swallow it...”

Colin said fiercely, with a sinister look in his eyes.

“You are my woman, you should eat my semen.”

Allison closed her eyes helplessly and swallowed the filth in her mouth with difficulty. Her son’s words made her feel desperate. Yes, she was already her son’s woman, what dignity did she have?

After a while, Allison felt something was wrong. Colin visited her less often, and he would always intentionally or unintentionally pull Ella to stay alone in the room. The siblings spent more time together, but they always lowered their voices when they talked, as if they had some secrets.

Although Allison’s mind told her not to think too much, she still felt a little uneasy. Colin had been spoiled by her. Would he feel that she, as a mother, could no longer satisfy him? Would he have his eyes on his daughter?

Thinking of this, she felt a pang of pain in her heart.

“Ding”, the phone made a crisp reminder sound.

Allison swiped the screen with a guilty conscience and found that the damn APP had assigned her a new task: “Allison, you’ve been doing very well recently. As a reward, you don’t have to do anything more extreme today. You just need to find a way to let Colin and Ella spend more time alone and create some ambiguous atmosphere. This shouldn’t be difficult for you, right?”

Allison gritted her teeth and resisted the urge to smash the phone to pieces. This devil! He actually encouraged her to arrange incest between her own son and daughter! Was he trying to kill her?

However, if they don’t do so, the shameful videos will be made public.

Allison closed her eyes in despair and nodded helplessly. Perhaps... this was also an opportunity? If Colin could divert his attention and stop pestering her, then her pressure would be much less, right?

Allison made up her mind and knocked on her daughter’s door.

“Ella, Mommy has something to ask of you.”

“What is it, Mom?”

Ella opened the door and looked at her mother puzzledly.

“Mom has been too busy with work lately and doesn’t have time to take care of your brother. Can you... spend more time with him? He seems to be in a bad mood recently and is always unhappy.”

Allison blinked and said casually.

“Oh...Okay.”

Ella hesitated, but nodded.

“I will spend more time with my brother.”

“My dear daughter, I feel relieved when you say this.”

Allison smiled with relief and kissed her daughter on the forehead.

“By the way, you can go to the amusement park together this weekend. I’ve bought tickets for you. Just treat it as a date, like a couple.”

“Mom...what are you talking about...”

Ella blushed and lowered her head, muttering softly.

“How can my brother and I be like a couple...”

“Silly boy, it’s just a joke.”

Allison rubbed her daughter’s head in a nonchalant manner.

“Okay, go find your brother. Be sure to keep him company.”

Watching her daughter run away, Allison’s face gradually darkened.

She stroked her phone and questioned the damn APP: “Are you satisfied now? I have let them date alone. Please don’t embarrass my daughter anymore...”

“Sexy and lovely Allison, don’t worry, as long as you are obedient, I won’t touch your daughter’s hair.”

The APP gave a chilling response.

“But if anything happens to them, it’s none of my business. After all, they are a pair of upright young siblings. They are together every day, so maybe sparks will fly...”
