for Advance Chapter
The old man heaved a long sigh and once again suppressed the urge to ejaculate. In fact, it was different from what many people thought. He obtained Yuan Yin when he lost his virginity... but it was the purest one, that is, the pure Yuan Yin that had been nurtured for more than ten years. It was the most helpful for the cultivation of internal strength. It did not mean that the Yin essence was gone from then on. It was just a change from opening the floodgates to a steady flow.
Internal martial arts have existed since ancient times. When internal jin reaches the stage of Dan Condensation, it transforms into even more miraculous internal force. Unlike the zhenqi generated by awakening, each step from internal jin to internal force is extremely difficult. Therefore, ancient masters devised many shortcuts, most of which pointed to the practice of dual cultivation... Intercourse between man and woman, complementing yin and yang, can promote the cultivation of internal strength.
In fact, most women are suitable for dual cultivation. After all, except for barren women, most women have Yuan Yin, and the most special among them are those with the most Yin body.
According to the records in the classics of dual cultivation, the most yin body is also called the most charming body. The yin essence is the most pure and abundant. According to the latest research theory, it is a woman with extremely high and abundant estrogen quality. Such a woman is the most feminine, with skin as delicate as snow, with a faint body fragrance, hair as black as ink and shiny, and not to mention the figure, which will fully display the soft beauty of the female body.
A girl with such features, even if she is not very good-looking, can still be considered a beauty...
What's more, one of the two sisters has grown up to be pure and beautiful, and the other is also a piece of delicate jade, a beauty in the making.
And their extremely charming bodies give them the carcasses that any man dreams of. Not only do they have graceful and beautiful figures, but they also have physiques that will flow like water with the slightest teasing. When they are fucked, their nectar will overflow, and their jade palaces and flower paths are always in an excited and congested state. Any man can get the most wonderful satisfaction from them. They can be said to be the most rare and peerless beauties.
Of course, although every man can be satisfied by them, it does not mean that they will be easily satisfied. Generally speaking, the stronger the Yuanyang, that is, the more male hormones are secreted, the more satisfied they will be.
And generally speaking, the bigger the penis of such a person is... Of course, there is an exception, that is, people who are born with unobstructed meridians and have rapid progress in cultivation. If such a person also has a very yang body, then as long as they find a very yin body to practice dual cultivation, then their cultivation will reach an incredible level.
The old man gnashed his teeth inwardly. He had encountered such a person before. Not only did he snatch away his granddaughter, who had long coveted and nurtured him for eighteen years, but he also sealed his cultivation with pure Yang Qi with a slap... and finally forced him to swear an oath, not to...
Fortunately, there's always a way out. Over a decade later, he finally encountered two sisters with the Ultimate Yin Body... Although he couldn't truly possess the younger sister due to her vows, a twist of fate... and he finally got her today. And that man died over a decade ago. Once he breaks through the barrier of his cultivation... then, hehe...
Thinking of this, the old man showed a happy and evil smile on his face. His big hands stroked the girl's thin waist and then her breasts. While rubbing, covering and kneading them, he slowly raised his hips backward and pulled the bloody penis out of the honey slit until the glans was still stuck inside. Then he pushed it hard, and the penis suddenly disappeared between the two delicate labia.
"Hmm~ah~wuwu~"
In his heart, the old man showed no pity for the young girl's newly broken virginity. He swung his waist violently and thrust hard. The young girl's slender waist twitched and twisted uncontrollably, and her arms clutched the bed sheet involuntarily. The ten slender toes of her beautiful jade feet stretched and curled, and suddenly tensed up and swayed with the thrusting...
Between the two smooth, round, and tender buttocks like boiled eggs, a penis stained with light blood was going in and out. The amplitude of each pullout was so amazing, and in the blink of an eye it sank into the vagina again, making the two smooth labia red and swollen, and the area near the round vagina that was stretched out was a bright red.
Seeing this scene, the young girl couldn't help but swallow her saliva, her beautiful watery eyes widened, and seeing her sister's lower body being ravaged like this, the girl felt a little bit of pity in her heart... After all, this was her biological sister who she had been with day and night for so many years, but as soon as she pursed her red lips, another picture emerged in her mind.
The scene where the sister and brother stood hand in hand and announced the "good news" to her...
The girl gritted her teeth, and the reluctance she felt soon faded away. Instead, she felt a slightly dizzying pleasure like being drunk. Then, she saw that as the old man's penis moved in and out, the bloodstains on the penis became lighter and lighter, as if they were being diluted by something.
She took a closer look and couldn't help but sneer at the corner of her mouth. It was the love fluid that was pouring out more and more that diluted the bloodstains. Every time it went in and out, the blood would become lighter. At the same time, a large amount of love fluid mixed with a hint of red flowed down the buttocks and snow grooves. After a while, the bed sheets were stained with spots and it was a mess.
The old man arched his waist and thrust in and out. Although the vagina was still narrow and extremely tight, as the lubricating liquid in the vagina increased, although it was still tight, every time the tender flesh went in and out it seemed as if it was trying to break through thousands of layers of obstacles. However, the rich love fluid filled the space between the tender folds of the flesh wall and the thick cock, providing excellent lubrication. It also made the slightly erected thick black cock make a thick, sticky gurgling sound like stirring a flesh tube filled with greasy fluid when it moved in and out.
The love fluid wrapped around the penis, after repeated stirring, gradually turned into a white and thick paste like foam and milk. As it was slapped, it stuck to the labia and the opening of the vagina. A stream of white fluid flowed out between the snow-white thighs, winding down, not only coating the delicate anus, but also flowing onto the wet sheets.
"Slurp, slurp, slurp..." Amid the sound of water, the girl's slender waist twisted and her hips trembled, but she could not escape the thrusting and stabbing again and again. The old man even came up with some new tricks, thrusting rapidly and deeply from time to time.
"Ah, um~ wuwu~ ah, ah~" The girl's cheeks were flushed, sweat was dripping, and her eyebrows were still furrowed, but apart from the pain, there was a touch of lustful and charming love between her brows.
The young girl looked at the sticky white liquid on the penis, a look of shock appeared on her face, and then she spat with disdain: "You are really slutty, you are not worthy of my brother at all..."
But if the young girl looked in the mirror at this moment, she would find that there was a charming blush on her little face. At the same time, her beautiful legs were tightly clamped together, becoming more and more wet, and she couldn't help but rub against each other slightly.
The old man exhaled a breath of foul air, panting slightly through his nose. After breaking the virginity, he fucked her for nearly twenty minutes in one breath. The girl orgasmed several times, and her tender flesh and delicate folds were moist and hot. From the opening to the end, it was like wrapping and gripping, tightly squirming. In addition, the delicate pistil at the end of the vagina was moving as if it would suck the glans. The intense numbness and sourness had already accumulated to the extreme.
When he was about to ejaculate, the old man suddenly grabbed the girl's two white and delicate ankles, which were as soft as snow, and pressed them hard against her breasts. The girl's buttocks slightly raised, and he adjusted his posture to a crouching position. Then he began to twist his waist, and his black buttocks rose violently. His big cock penetrated deep into her vagina, like a cicada attached to its tail, and began to thrust in and out fiercely!
"Pah pah pah...!"
After hundreds of long and fierce thrusts, the old man reached deep into the heart of the vagina, and his glans rubbed the delicate cervix, slightly opening it. The agitated cervix bit it lightly, and the sour and crisp pleasure suddenly came like a tide.
The muscles of the dark buttocks tensed up, and the thick rod became more and more swollen and firm. Then, in the violent beating, streams of hot and thick semen shot out, not only instantly penetrating the heart of the flower, but also filling the narrow honey channel from the delicate folds to the fine wrinkles, with a sticky and greasy liquid without a trace leaking out.
