When Chu Jiangnan stripped her naked, Du Yuyan decided that he wanted to insult her, so she was sober and took the opportunity to use the magic sect technique, hoping to find an opportunity to escape. But when she exposed her delicate body and tender flesh to Chu Jiangnan's eyes, he disdained her and turned to tease Yan Jing'an.
Did I even compare to her seducing a man?The arrogant Du Yuyan said that she would not admit defeat. When she saw Yan Jing'an taking away her first kiss by Chu Jiangnan, an inexplicable pleasure arose in her heart.
Gradually, Chu Jiangnan could no longer suppress the erotic impulse of his body. He bit Yan Jing'an's delicate and small earlobe and yelled: Jing'an, from now on, you will be mine.
The soft and soft body was hugged tightly by Chu Jiangnan again. Yan Jing'an was ashamed and anxious, shocked and scared, but how could Feng Huáng, who was in trouble, be able to defeat the Canglong who soared into the sky?
Yan Jing'an's internal strength had been consumed long ago, and now even ordinary women are not as good as that. It can be said that he has no power to tie a chicken. How could he be Chu Jiangnan's opponent?
After a little hard struggle, I panted and sweated profusely, and my pretty face turned red.
If it were on weekdays, whether facing Yan Jing'an or Du Yuyan, Chu Jiangnan would not have any chance at all. But by chance, he not only had a chance, but also had two chances with great luck. Chu Jiangnan hugged Yan Jing'an's weak and boneless waist with both hands, gradually expanding the scope of movement and wandering all over her body...
Everyone knows the status and reputation of Cihang Jingzhai in the world. Yan Jingan, as the master of Cihang Jingzhai, had a unique vision. He chose Zhu Yuanzhang, who was not favored in the early days, and called on the martial artists of the world to use it for him, help him defeat Chen Youliang, expel the Mongols, and establish the Ming Dynasty.
Yan Jing'an walked around the world, with white clothes, light gauze, ice face, frost sword, and countless fans. Behind him is Zhu Yuanzhang, the lord of the Central Plains. No matter who sees her, she is respectful and dares not be negligent, and does not even dare to speak insults. How could he have suffered such great grievances?
Yan Jing'an, who is as beautiful as a fairy, is still a pure and virgin body. Under the flirting and teasing of Chu Jiangnan's demonic spirit, he is like a gentle lamb, allowing him to play lewdly on his delicate jade body.
Chu Jiangnan looked at her beautiful and beautiful face that was gradually flushing. A faint orchid fragrance unique to her virginity penetrated into her nose and penetrated into her heart and lungs. The lustful man couldn't help but feel the desire ignorant.
Her hands wandered around Yan Jing'an's body, first gently stroked her jade cheeks and peach cheeks, rubbed and touched her, and felt that the tentacles were tender and smooth. Her youthful and tense skin gave Chu Jiangnan an unprecedented enjoyment.
His hands slowly moved downward, slid past Yan Jing'an's slender and smooth jade neck, round shoulders, and climbed up to the plump and smooth towering height through a white skirt.
Um……
Yan Jing'an let out a hot and seductive moan.
Chu Jiangnan held Yan Jing'an's plump and plump erect in both hands, and at the same time, he lowered his head and kissed him wildly in his tender and tender mouth that was as breathing as orchid.
Ah……
Yan Jing'an's jade cheeks, which were still tear-stained, were blushing than fire, and he bit his jade teeth lightly.
Chu Jiangnan squeezed her plump place hard, and Yan Jing'an said with a whistle, and his lips fell. Chu Jiangnan took the opportunity to sweep his army straight in. The hot poisonous tortoise swept over the tender and sweet soft tongue, sucking the intoxicating fragrant liquid in her mouth vigorously.
Chu Jiangnan looked at Yan Jing'an, who was so holy and unparalleled in his arms. His beautiful face was like fire, his bright water eyes were full of anger, his figure was graceful and skin was delicate and delicate, his legs were slender and strong, his fragrant buttocks were plump and strong, and his lower abdomen was flat and solid. It was really beautiful and inspiring.
The two soft jade buds gradually grew and stood up as strong as hard rocks. Yan Jing'an, whose heart trembled slightly, was angry and anxious, and was disgraceful. She had been left in the empty door since she was a child, devoted herself to the Tao, pure and clean, and had never had any skin kinship with any man in her life, let alone being touched by a man like this?
Which girl doesn’t have spring?How can a virgin be so fond of love? Even if this virgin is a fairy.
Besides, the place where Chu Jiangnan’s hands desecrated was Yan Jing'an’s sensitive jade breasts, although they were dressed in plain clothes.
The reason why Yan Jing'an can still wear clothes intact is that in Chu Jiangnan's eyes, the clothes are not hindering, but interest.
Yan Jing'an, who had soreness and weakness in his limbs, went from his initial struggle to his soft words to his later soft words, but under the influence of Bai Xiu's lustful nature, Chu Jiangnan had already become very lustful and burned with desire, so how could he give up?
Chu Jiangnan's magic hands caressed Yan Jing'an's three souls, seven souls, their pretty faces were like fire, their delicate body trembled as if they were struck by lightning, and their body was soft and crisp.
You, let me go... Let me go...
Yan Jing'an felt dizzy in her cheeks. She was both ashamed and afraid, but she was unable to resist the increasingly strong physiological reactions of her body.
Yan Jing'an felt that Chu Jiangnan's hands seemed to have incredible magic. She was determined to devote herself to the swordsmanship and had even stopped her daughter's menstrual period, but at this time the man pressed her hands on her swollen and huge peaks. Her mind seemed blank, and there was a vague idea of hope in her heart that she could be immersed in this strong sense of comfort.
Under the dual influence of the demonic energy and the lewd breath in the air, Yan Jing'an's slender jade hand, which was as crystal clear and white as jade-warm, completely gave up resistance, changed to pushing, and held Chu Jiangnan's big hand that he wanted to rub on the angrily snow breasts.
Chu Jiangnan showed an evil smile on his face, and his hands easily got rid of Yan Jing'an's simple hands, then gently untied the skirt straps of the beautiful woman's delicate body, which was stiff due to tension, and her big hands slid into the loose skirt like a snake...
Gently rubbing the soft and smooth ice-skinned skin around Yan Jing'an's waist, Chu Jiangnan's big hands exuding a hot and warmth stroked his soft and smooth belly under his soft underwear...
When his big hand climbed the mountain and waded through the water and arrived at Yan Jing'an's delicate virgin, her shy heart seemed to jump out of her chest, and her delicate jade body trembled endlessly because of her nervousness.
As her skills diminished, Yan Jing'an could not maintain the highest Zen realm and Taoism she learned from "Sword Book". She had a heart of harmony. When she realized that she was going to be so rippling in spring at this moment, she couldn't help but feel embarrassed and felt sad.
Chu Jiangnan pressed Yan Jing'an's evil hand gently rubbed, his technique skillfully and experienced. The strong stimulation made her unable to help but pant and hum.
Yan Jing'an's moans and panting deliberately suppressed by Yan Jing'an's mouth, Chu Jiangnan felt something in his heart swelling violently, his body seemed to explode, a low roar sounded in his throat, and his deep red eyes showed a strong desire for carnal desire.
The lustful Chu Jiangnan was no longer gentle, his movements were rough and violent, and he suddenly threw Yan Jing'an to the ground, forced his two straight and straight legs, and stretched out his hand to tear it around.
A sneer sounded, and half of Yan Jing'an's simple clothes were roughly torn apart by Chu Jiangnan, revealing the rich spring scenery hidden in it.
We are often moved by the good deeds of evil people, such as the scene where Mei Chaofeng, who practices the Nine Yin White Bone Claws, bandages the wounds of a child injured in the dark, such as a photo of Hitler holding the child when he was performing a show...
The lustful man completed the sacred tasks that could not be completed in the hearts of countless wolf friends. He originally planned to push Qin Mengyao, but he didn't expect that he was lucky enough to let Yan Jing'an go. It seems that people really need to do more good deeds, and good people are good to hug!
The sky is Ah, the earth is Ah, if there are really gods in the world, I guess the first person to be struck by lightning is this chromatic embryo.
Chu Jiangnan exhaled a white and thick breath in his nose, staring at the panicked and helpless little lamb under him, and reached out to pull off her white underwear that covered her breasts, still on the ground.
If he met Chu Jiangnan, this would definitely be a rare personal treasure. Now he doesn't have the intention. With a click, the white string broke and the underwear fell off. In an instant, two peerless breasts jumped out, shaking and turbulent in front of the man's eyes, swaying and shaking in front of the man's eyes, swaying in an extremely charming breast wave.
Yan Jing'an's tender little mouth let out a sad and disheartened scream, shaking Zhen's head desperately, but he had no internal strength in his body and could not break free from his hands and legs. The more he struggled, the more skin was exposed to the air. In a moment, the fragrant sweat was dripping, and the delicate skin surfaced with a beautiful bright redness.
Seeing Yan Jing'an's naked tender white flesh and two bright red spots on the plump and towering height, the red color in Chu Jiangnan's eyes became stronger and stronger, and the flame of desire deep in his heart gradually became a prairie fire.
Regardless of Yan Jing'an's hoarse resistance, Chu Jiangnan's hands were covered with white and tender breasts that were covered with ice and snow. After a long time, he let go of the Yufeng covered with bright red and wet marks.
The conquerors continued to gallop across the battlefield and opened the territory to break the ground. When the beauty's face was trembling with red face, they slid across the mountain plain and came to her beautiful belly button, and at the same time began to pull the ribbon around her waist hard.
Yan Jing'an was panting, as if a mountain was pressing on his chest, and it would still be like fire.
The crimson fragrance scattered in the air around him became more and more intense, and his slightly trembling tall peaks became more and more full under the stimulation of the lewd breath. Looking at Chu Jiangnan, who was lying on his delicate body and constantly ravaging his snow-white body, Yan Jing'an's eyes suddenly became extremely calm and clear.
Chu Jiangnan, who was burning with desire, only cared about invading Yan Jing'an's body without any resistance, venting her original desires, and did not bind her hands. Yan Jing'an, who had lost her internal strength, was just an ordinary woman with weak body, and her pink fists showed her legs and could not hurt Chu Jiangnan at all.
If Yan Jing'an was really suppressed and unable to move, Chu Jiangnan might feel that he would have lost a lot of fun. Wouldn't men be good at this?
Yan Jing'an's eyes were cold and as if it had not melted for thousands of years. He avoided Chu Jiangnan's red eyes burning with desire, and each of his hands made a graceful and graceful gesture, and spit out a few clear Sanskrit words like a dream in his sweet lips.
Ossa Binpo, Bound, Shutuo, Damosa Binpo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutuo, Shutu
Yan Jing'an's soft and plump lips trembled quickly, and Buddhist mantras were singed in his mouth.
The three secrets of god, soul and soul are combined, and the five aggregates of color, feeling, thought, action and consciousness are born. Every word is like a thunder and thunder. Chu Jiangnan's whole body is trembling when he heard this. His eyes flashed with a blank look. His hands stopped the invasion and fell to the ground like a loss of his soul.
Yan Jing'an's eyes were soft and peaceful, and his pretty blushing face suddenly became calm and calm. Then, it seemed like a small stone was thrown to cause a ripple, gradually expanding, turning into a touching smile that was beyond words and could not be expressed in words, and was transcendent to any common thoughts and delusions.
The lost Chu Jiangnan and Yan Jing'an's eyes touched, and immediately, huge waves surged in their hearts, shocked, frightened, and scared. The sponge of desire that burned the sky quickly disappeared like a sponge of burning desire absorbed water.
In order to resolve the invasion of Chu Jiangnan, Yan Jing'an used the supreme skill recorded in the Buddhist mysterious art "The Great Brahma King Asking Buddha for Questions and Resolving Doubts" to protect his innocence. Because of the entire casting process, it cannot be made mistakes or interrupted in the middle, otherwise it will be wasted all previous efforts, and it is not easy to perform.
Did I even compare to her seducing a man?The arrogant Du Yuyan said that she would not admit defeat. When she saw Yan Jing'an taking away her first kiss by Chu Jiangnan, an inexplicable pleasure arose in her heart.
Gradually, Chu Jiangnan could no longer suppress the erotic impulse of his body. He bit Yan Jing'an's delicate and small earlobe and yelled: Jing'an, from now on, you will be mine.
The soft and soft body was hugged tightly by Chu Jiangnan again. Yan Jing'an was ashamed and anxious, shocked and scared, but how could Feng Huáng, who was in trouble, be able to defeat the Canglong who soared into the sky?
Yan Jing'an's internal strength had been consumed long ago, and now even ordinary women are not as good as that. It can be said that he has no power to tie a chicken. How could he be Chu Jiangnan's opponent?
After a little hard struggle, I panted and sweated profusely, and my pretty face turned red.
