Pei Qingyu knelt on the bed, with the dildo on his waist deeply inserted into his biological mother Du Ruoyun's vagina, the secret passage where he was born.
This posture is different from the usual woman-on-top position, and Pei Qingyu, who is on the bottom, can also exert force easily.
She put her hands on Du Ruoyun's waist and thrust her butt upwards hard, as if what was tied around her waist was not a dildo but a sharp dagger.
The vagina, which had not had any visitors in seventeen years, had already become as tight as a virgin. Although it was lubricated with a large amount of vaginal fluid, when the dildo was just inserted, a tearing pain still came from the lower body.
Before she could recover from the pain, Pei Qingyu had already started thrusting hard like a brutal man. Each impact hit her clitoris, making her brain numb and she screamed in pain with every thrust.
Because of her posture, Du Ruoyun was able to overlook Pei Qingyu who was looking up at her. She didn't want to see the strong resentment in her daughter's eyes, nor did she want to face the humiliating fact that she was fucked by her own daughter after more than ten years of abstinence, so she lay on her back and closed her eyes.
However, Du Ruoyun soon discovered that once she closed her eyes, the functions of her other senses seemed to be enhanced, and the pain, numbness, vibration and fullness from her lower body caused by the impact became increasingly difficult to ignore.
Not only that, she also sensitively noticed that although Pei Xuan, who was sitting behind her, was still playing with her breasts with one hand, his other hand had already moved to her anus and then inserted it without hesitation.
"Ah!" Du Ruoyun, who had been trying to ignore Pei Xuan, could no longer pretend. She turned around and scolded Pei Xuan, "What are you doing!?"
"Get ready." Pei Xuan replied with a smile, "I said I'd fuck you with my sister. Since my sister has taken your pussy, I'll have to fuck your asshole."
"No!" Du Ruoyun objected loudly in panic.
"No?" Pei Xuan pretended to be confused. "If I don't fuck your asshole, can I fuck your mouth? But this position isn't appropriate either."
"No!" Du Ruoyun was so angry at Pei Xuan's shameless attitude that she blurted out, "You can only fuck from the front!"
"Are you so eager to let me fuck you from the front?" Pei Xuan said loudly with a deliberate smile, "Are you not satisfied with your daughter's fucking?"
Du Ruoyun came from a prominent family and had been well-educated over the past ten years. She had never heard such obscene words before, let alone used them in an argument.
Naturally, he was completely defeated when arguing with Pei Xuan about this matter. He was so angry that he didn't know what to say.
On the contrary, Pei Qingyu listened to Pei Xuan's "provocation". Although he knew that this was not Du Ruoyun's original intention, he was still very angry and increased the force of the impact.
Pei Xuan dug his fingers into Du Ruoyun's anus a few times and then withdrew them with satisfaction.
Du Ruoyun had already been fasting, and her asshole was completely useless, practically spotless. However, Pei Xuan still bought a bowel cleansing pill from the system store as usual, and while stuffing it into Du Ruoyun's asshole, he asked with a grin, "Has Pei Wanjun ever fucked your asshole?"
The name made both mother and daughter stunned for a moment. Pei Qingyu continued to work without changing her expression, while Du Ruoyun shuddered in anger and denied it flatly: "Of course not!"
"Really? Then I'll deflower you today!" Pei Xuan thrust his cock, which had already become painfully hard, stretched open the layers of soft flesh at the entrance of Du Ruoyun's anus, and thrust it in fiercely.
The intense pain in her anus, as if it was cut by a dagger, made Du Ruoyun scream, and her upper body involuntarily fell forward on Pei Qingyu.
Du Ruoyun, tears in her eyes, trembled as she leaned on her daughter's shoulder, her tone still vicious: "I will... kill you! I should have... killed you... and your mother... a treacherous woman who gave birth to a beast worse than a pig or a dog..."
When Pei Xuan heard Du Ruoyun mention his original body's biological mother, he remembered the details of the dispute that year.
He grabbed Du Ruoyun's long hair that flowed down her smooth back and forcibly pulled her up from his daughter's shoulders. Then he whispered in her ear, "There's something I forgot to tell you. Yu Fei didn't seduce Pei Wanjun. It was Pei Wanjun who raped her. She didn't tell you because she was afraid it would affect your pregnancy. You probably don't know about this, right?"
Yu Fei is the name of Pei Xuan's original mother. She is also the personal maid and best friend that Du Ruoyun brought from her mother's home to the Pei family.
After the incident was exposed, Du Ruoyun drove the pregnant Yu Fei out of Chang'an City without asking any questions, causing her to suffer from poverty and illness and die young.
"What?!" This news hit Du Ruoyun's heart like a bolt from the blue. Her first reaction was naturally disbelief. "I don't believe it! You're just looking for an excuse to get back at me..."
"Excuse me?" Pei Xuan smiled nonchalantly. "Do you think I need an excuse to fuck you? You're beautiful, have a great figure, are both Heavenly Rank strong, and are the mother of Jade Slave. You can be said to be a perfect mother-daughter pair. No matter what happened with Yu Fei back then, I'm determined to fuck you. If you don't believe me, you can go back and confront Pei Wanjun."
"How could it be..." After hearing Pei Xuan's arrogant declaration, Du Ruojun had already believed it for 80% of the time. Her mentality, which had been on the verge of collapse, was suddenly broken. She felt hopeless and tears burst out.
Du Ruoyun and Yu Fei grew up together. In name, they are master and servant, but in reality, they are as close as sisters.
Because of this, Du Ruoyun, who had just given birth to Pei Qingyu seventeen years ago, heard that Yu Fei was pregnant with her husband Pei Wanjun's child. The arrogant Du Ruoyun felt that she was deeply betrayed by Yu Fei.
Du Ruoyun was so angry that she didn't even give Yu Fei a chance to explain and directly sent people to drive her out of Chang'an City.
Over the years, she no longer took Pei Wanjun seriously, but she still felt resentful towards Fei.
Unexpectedly, the truth was revealed today. Yu Fei did not betray her, but she was the one who betrayed their friendship and trust, and indirectly killed Yu Fei. Du Ruoyun suddenly fell into endless pain and regret.
Seeing Du Ruoyun finally burst into tears with a look of regret on her face, Pei Qingyu was not satisfied, but instead felt more resentful, because her crying was not for her but for another person.
When Du Ruojun leaned on her shoulder before, Pei Qingyu subconsciously stopped thrusting. Now that her anger had reached its peak, she started thrusting again with unprecedented momentum.
At the same time, Pei Xuan's penis had almost adapted to Du Ruoyun's tight and smooth anus. He grabbed Du Ruoyun's long hair with one hand and held Du Ruoyun's round shoulders with the other hand. He and Pei Qingyu exerted force at the same time, and began to thrust in and out amid the squirming of the tender flesh in the anus, sandwiching the crying female monk of the Heavenly Stage from the front and the back.
