Who taught you to cultivate immortals like this?

Chapter 240 Chapter 322 323 A mature woman’s emotions are like a landslide and a tsunami!Xu You who lost his mind and his aunt kissed passionately

It wasn't until Huangfulan's waistline felt hot enough that Xu You stopped for a moment. He looked up and saw that Huangfulan's ears were already covered with a lot of blush.

"Auntie, how do you feel now?"

"Just like that"

"Have you felt the detoxification effect I mentioned?"

"That's right," Huangfulan said vaguely.

"Then I'll continue." Xu You smiled.Then he released his hands on his thin waist and moved them down slightly.

He was about to place it on Huangfulan's eye-catching buttocks. At this time, Huangfulan shouted directly,

"What do you want to do?"

Xu You paused and said, "Knead it, Auntie."

"How dare you?" Huangfulan raised her eyebrows and stared at Xu You.There was a slight blush on her face, and she didn't know whether it was because she pressed the beauty button just now or because she was angry.

"Isn't it possible?" Xu You asked back, then pretended to be enlightened and said, "Auntie, you misunderstood, this is not a matter of men and women being intimate.

This is just a massage to help you detoxify. As you know, there are the best detoxification spots here. "

"Still talking nonsense!" The blush on Huangfulan's face became more obvious, "I just believed your nonsense just now, how dare you say that now?"

"Auntie, how could I be talking nonsense? I didn't just ask you if you have experienced the effects of detoxification. You said you have!" Xu You raised his voice slightly.

"I just followed your words!"

"Then why are you blushing, Auntie? This is obviously a sign that Qi and blood are running sufficiently to detoxify!"

"You" face the fact that Huangfulan's face is rosy and it's hard to quibble. You can't tell Xu that it's because you were pressed too comfortably, right?
"No way! You can't touch this place!" Huangfulan said without any doubt, "Auntie can't let you mess around!"

"Okay, okay, don't touch if you don't want to touch." Xu You could only take a step back and said.

"Don't mess around!" Huangfulan warned.

"Auntie, with your strength here, how can I dare?" Xu You said angrily.

"Huh?" Huangfulan raised her eyebrows slightly, "You mean if one day you are stronger than me, you dare to force yourself regardless of whether I agree or not?"

"That's not what I meant, how could it be possible?" Xu You quickly smiled, then stretched out his hand to press on Huangfulan's back,

"Auntie, lie down and I will continue."

Huangfulan didn't say anything more, but gave Xu You a final look to warn him not to mess around, and then lay down in the original position.

Xu You looked at his aunt's plump buttocks and felt a little regretful that he was not blessed today.

Then, Xu You put his big hand directly on Huangfulan's thigh. As soon as he put it on, he could clearly feel that Huangfulan's whole body began to tighten subconsciously.

"Auntie, relax so that I can detoxify properly." Xu You said softly.

"Giggles, I said I was ticklish." Huangfulan couldn't help laughing again.

Xu You relaxed a little more. Once he relaxed, he could clearly feel the change in Huangfulan's breathing.

It's obvious that thighs are one of Auntie's weaknesses.

Xu You suddenly understood. Of course, he didn't have any other obscene thoughts, it was just a purely technical massage.

Needless to say, the feel of Huangfulan's thighs can no longer be described in words. It is just the right amount of plumpness, not even a little too much or a little less.

Such top-notch long legs are the kind that you will never tire of admiring all your life. They are simply heaven-defying.

I used to think it was awesome just by looking at it, but now I know how awesome it is after trying it myself!
Xu You gently held it without any hesitation, and his legs were rippling like water, which was pleasing to the eye.

"Auntie, your legs are the most beautiful legs I have ever seen, bar none." Xu You praised sincerely.

"What nonsense are you talking about!" Huangfulan snorted with her head buried in an uncomfortable voice.

"Auntie, relax, don't tense up." Xu You said again.

"It's up to you to do whatever you want!"

"Okay." Xu You smiled hoarsely. He knew that this was no longer something that his aunt could control subjectively. It was purely an instinctive conditioned reflex to say yes.

In the following time, Xu You also kept quiet, massaging and rubbing carefully while feeling his aunt's long, top-notch legs.

A few quarters of an hour later, Xu You touched the sweat on his forehead and finished massaging his thighs.

This is really a top-notch physical job. The main thing is to devote a lot of energy to fighting the beast in your heart when massaging.

If you don't control it well, you will lose your mind. If you lose your mind, your aunt will kick you out of Tianque City.

When Xu You let go, Huangfulan's tense body slowly relaxed and became less stiff.

Although she didn't say anything just now, she was just like Xu You, fighting against the beast.

And the beast in her heart is much stronger than Xu You. After all, Xu You just had a cool day yesterday, so he can withstand it today.

But Huangfulan was different. She had been alone for most of her life, which was decades of suppression. You can imagine how powerful the beast in her heart has become now.

The ability to hold on was all due to her terrifying willpower and the constraints placed on her by her aristocratic family environment.

How could Huangfulan dare to act recklessly before she had the strength to do whatever she wanted? If the time came, it would harm others and herself, which would actually make Xu You passive.

But how could he bear it if he kept holding on like this, especially when Xu You was massaging his thighs just now.

That beast was simply unprecedentedly powerful. After all, it was a woman's thigh, and the sensory experience was completely different from other places.

If Xu You had been here just a moment longer, Huangfulan couldn't even guarantee that his beast would have swallowed her up completely.

Then she turned around and swallowed Xu You completely.

Now Huangfulan really regrets agreeing to Xu You to experience this. She underestimated Xu You's ability and overestimated her own willpower.

She didn't expect that this little guy was so proficient in these things, and could always beautify herself accurately, and even made it impossible for her to say no.

Then it leads to the current situation where it is difficult to get off the tiger. You are really reluctant to ask Xu You to stop. This feeling is really great, and you can't even ask Xu You to stop.

But if you say you want to continue, your resistance will be tested again, which will put a lot of psychological pressure on you.And this feeling of being “sick of something” is particularly stressful.

Huangfulan felt miserable and could only continue to hold on as if nothing had happened.

Fortunately, the thigh area is finally over, and the tense nerves can finally relax a little.

"Is it over?" Huangfulan asked aloud.

"Not yet, Auntie, are you in a hurry?" Xu You asked.

"That's not true. You can continue to complete the process. I'm lying on my stomach all the time and I'm tired."

"Okay aunt, I'll do it as soon as possible."

Xu You smiled and then put his hand on Huangfulan's calf.The two of them felt a little more relaxed in this place, and there was no tense atmosphere like before.

As soon as his hand was placed on Huangfulan's calf, Xu You could feel the delicateness and softness underneath it through the thin clothes.

Auntie's calves are of the slender type. Such calves are the most beautiful calves. They are straight and thin. They are the kind of slender calves that countless women want most.

Xu You was not surprised at all about the top quality of Huangfulan's calves, because the whole body of her aunt was top quality, without any flaws.

Xu You rubbed his aunt's calf with his fingers and said, "Auntie, your meridians are not very clear. It's because you are too tired, sit all the time, and are stressed.

You have to press it frequently in the future, especially on the lower legs. Blockage of Qi and blood will not be good for your health. "

"Do you want to listen to what you are saying?" Huangfulan said angrily, "I am a monk in the realm of heaven, not a mortal!"

"Auntie, this is your fault. Whether or not you are a monk is completely different. The meridians, energy, blood, etc. I am talking about have nothing to do with cultivation.

That is an illusory statement and an ideological existence.It's like there are many powerful female monks who are not in good health and look bad. Why?
This is what I mean when I say that Qi and blood are blocked.In short, aunt, you should take good care of your body. "

Huangfulan was thoughtful. What Xu You was talking about was indeed a phenomenon. There were indeed many female monks suffering from female problems.

"I know. Pay attention in the future." Huangfulan responded without retorting.

Xu You raised his head and briefly glanced at his aunt's alluring curves, and then he continued in two words, "Actually, there is another point that is the most critical, and the conditioning effect is also the best.

If it is not regulated for a long time, it will lead to endocrine disorders and various problems. "

"What is conditioning? What is endocrine?" Huangfulan asked puzzledly.

"Endocrine is a word for overall planning, and it refers to the state of the whole person. Just like Auntie, do you often feel upset, inexplicably irritable, and in a bad mood? Sometimes your physical condition also has inexplicable changes. anger?"

"Huh? What next?" Huangfulan asked.

"Right, this is what I said about a series of problems that will result from not being reconciled for a long time."

"What exactly is the blend?"

"Ahem, this um...is the reconciliation between men and women..."

"Male and female..., how presumptuous! What nonsense are you talking about!" Huangfulan shouted directly.

"Don't worry, Auntie, the matter between men and women is the way of heaven and earth. This is in compliance with the way of heaven. Auntie, don't be afraid of it like a scourge.

The instinctive path of such a person is positive and sunny.”

"Shut up!"

Xu You was interrupted angrily by Huangfulan before he could finish his words, so he had no choice but to shut up and dare not say more.After a while, he continued,
"Auntie, actually"

"To shut up!"

"I"

"To shut up!"

"I actually wanted to ask you if your feet smell?"

"Shut up? What did you say?!" Huangfulan turned her head and glared at Xu You, the anger in her eyes soaring again.

Xu You's eyes fell on the pair of jade feet. He swallowed and said, "Auntie, only the feet are left now. Let me ask casually."

"Can feet also detoxify?" Huangfulan asked.

"Of course." Xu You nodded with a smile.

"You can detoxify everything, right?" Huangfulan became increasingly annoyed.

"Auntie is smart, but feet can indeed detoxify. Auntie, think about it, the sweating on your feet is very likely, which means that the possibility of detoxification is greater. Do you think this is true?" Xu You said.

"Oh." Huangfulan snorted, "I use the divine spring to nourish my skin every day. Every place smells so good. How could it stink!"

"Every place smells good? I don't believe it."

"If you don't believe it yourself, believe it or not!" Huangfulan realized that she didn't fall for Xu You's provocation and just glared at him fiercely.

"I believe it, I believe it. Auntie's feet must be the most fragrant feet in the world." Xu You immediately put on a smile.

"Then according to what you just said, the more places where water comes out, the more powerful the detoxification will be in that place?" Huangfulan asked smoothly.

"That's true." Xu You also answered subconsciously.

But as soon as he finished answering, he and Huangfulan were both stunned.

Obviously at this moment, both the veteran driver Xu You and the mature aunt thought of something, and then a weird atmosphere spread between them.

Xu You, who was as thick-skinned as he was, quietly watched his aunt's reaction, his heart was filled with excitement.

He didn't expect that such content would come out of the exchange between the two.

"What are you looking at! Do what you want!" Huangfulan saw Xu You's eyes and immediately said with a cold face.

It's just that the blush on her ears perfectly reflects the shame in her heart at the moment, why did she talk like this?

What happened to me today!
Isn’t it just massage?Why have you lost all your wisdom?

Huangfulan, Huangfulan, please wake up and be normal!You can't do this!

At this moment, Huangfulan was trying hard to adjust her mental state, and she must not go astray again.

"Okay, Auntie, I'll help you right now." Xu You quickly moved his butt down a little further, and first put his hand on Huangfulan's instep.

He said, "Auntie, it is true that feet can detoxify. Auntie, you also know that there are many acupuncture points and meridians on the feet.

These acupuncture points and meridians connect our whole body, and physical therapy on the feet can have a very good health care effect on the whole body.

Therefore, a specialized business called pedicure has emerged. "

"Pedicure?"

"Yes, it is very popular in some places, because professional foot massage is really good for the body." Xu You spoke like a treasure.

"Then you give it a good treatment and I'll take a look."

Looking at Huangfulan's jade-like feet, which were as white as jade and crystal clear, Xu You moved his throat again, "Okay, auntie, then I'll get started... let's get started."

After saying that, Xu You directly took hold of Huangfulan's right foot with one hand and held it in his palm like a beautiful jade.

Even the toes exuded endless beauty, and there was not even a single flaw on the delicate skin, and there was even a strange fragrance!

It has to be said that Huangfulan takes good care of her body to an extremely exaggerated level, even her jade feet can smell like this!

It seems that taking a dip in Shenquan every day is really a well-earned reputation.

Isn’t it true that every place is so fragrant?

While Xu You began to think about it, he began to give his aunt a foot massage.

The feeling of beautiful feet in my hands is as delicate as jade, as silky as hell, and as exquisite as death.

"Giggle, giggle, how presumptuous! Are you doing a pedicure! What are you doing!" Huangfulan, who was ticklish, laughed and scolded.

"I'm going to warm up first, auntie." Xu You smiled. He was indeed a bit out of shape.

But there is no way. Xu You has no resistance to Yuzu, especially such a top-notch Yuzu. How can you let him resist?
The fact that he didn't take a bite just now shows that he has very strong determination.

Fortunately, Xu You's anus strength was now at a very good level after he had just massaged it all the way down. He massaged Huangfulan's feet professionally and conscientiously first.Get a quality pedicure and enjoy a happy life.

Xu You's technique was very good. He rubbed her feet and made Huangfulan giggle from time to time. Auntie was indeed very ticklish.

After a few minutes, the pedicure was finally over.

Xu You wiped the sweat from his head again, and Huangfulan's whole posture was now extremely relaxed.

This service from top to bottom really made her experience a feeling of happiness that she had never experienced in her life.

Looking back on what Xu You said at the beginning, he was indeed not lying to himself. He was very accomplished in this area.

"Auntie, how do you feel now?" Xu You sat on the edge of the bed, openly admiring the curve of his aunt's back, and asked with a smile.

"Not bad, little guy, you do have a way." Huangfulan turned her head, supported the side of her face a little, and looked at Xu You lazily with a rosy face.

With her mind and body relaxed, she subconsciously began to look at Xu You charmingly.

Seeing her aunt's charming appearance, Xu You couldn't move his eyes away, just staring at her aunt's flourishing appearance.

"Serving Auntie, I learned everything for Auntie."

"Have you massaged other aunties before?" Huangfulan asked.

Xu You said with some resentment, "Auntie, how many times do I have to tell you before you believe it? I have served you, auntie. What's the point of deceiving you about this kind of thing?"

"Not even your master?"

"No." Xu You shook his head directly and said, "The most I can do is let my master loosen his shoulders, and nothing else. Like Auntie, you are the only one who had your whole back removed just now.

As I said before, I really went to learn this for you, auntie. "

"Auntie, I believe you. Little one, you are so kind. If you make this a habit for Auntie in the future, wouldn't it mean that Auntie can't live without you?"

As Huangfulan spoke, she began to bow her instep charmingly again, and then gently rubbed her instep on Xu You's calf.

After being served, Huangfulan was not at all as restrained as she was in the service state just now, and became the aunt who could tease Xu You as much as she wanted.

I couldn't help it. I felt a natural sense of insecurity when I was being served just now. I always felt like I could be manipulated at will by Xu You.

He was like meat on the chopping board and allowed to be served by Xu You.

It felt very strange and wonderful, making me feel like a little woman.Nervous, awkward, uneasy.

Now that she has pressed it, her queen's mentality has returned unknowingly.Then I thought about teasing Xu You and trying to manipulate Xu You.

Xu You lowered his head and looked at the way his aunt's instep was rubbing his side leg, and then looked at her charming expression.

He replied, "Then don't leave Auntie. I will be bound to Auntie from now on. If Auntie wants to massage her one day, I will be there to serve you at any time."

"You're so good. Auntie will remember that. Don't worry, little guy. Auntie won't treat you badly in the future." Huangfulan said with a smile.

"Hey hey hey."

"Okay, now that I've finished pressing the button, it's time for me to get up." Huangfulan yawned.

"Huh? Auntie, who said it's finished?" Xu You asked.

"Well, what do you mean? Isn't it all done?" Huangfulan asked.

"No." Xu You shook his head, "Where are you now? Isn't it that the front is not here yet?"

"Front?" Huangfulan's eyes widened in astonishment.

"Yes, the whole process is like this, first from behind and then from the front." Xu You nodded.

"I'm lying here, and you're doing what you did when you pressed my back just now?"

"Yes."

"How dare you!" Huangfulan immediately hit Xu You on the forehead with a loud bang, "Don't think that you can do whatever you want now that you have served me well just now!"

"No, aunt, am I trying to be wrong or are you trying to be wrong? Do you think I have the guts to do whatever I want now?" Xu You said angrily,

"You're just lying there. Are you blind? What can I say to you?"

"Then" Huangfulan hesitated, "then what other places can be pressed on the front?"

"The belly is enough." Xu You replied seriously, "The lower abdomen is the foundation of a woman, the gate of life! If you nourish the lower abdomen, then for a woman, everything will be nourished!"

"That's right, then Auntie has misunderstood you, little one."

Huangfulan changed her expression and turned around with a smile.

The plump and exquisite curves moved in front of Xu You, and he soon lay there.

This is a different look compared to lying down. Huangfulan folded her hands on her lower abdomen, and her plump legs were pressed together without any gaps.

The curves of the waistline and hips became more and more terrifying and exaggerated. In Xu You's eyes, how could such a slender waist and such plump buttocks be on the same body.

It can be described as a graceful and colorful picture of a top-notch beautiful woman, a mature woman, and a noble lady lying down.

"What are you looking at? Haven't you seen enough?" Huangfulan narrowed her eyes with a smile and said charmingly.

Xu You looked at his aunt's pretty face like a flower, coughed twice and sat down next to him, curiously asking, "Auntie, why are you lying down different from lying on your stomach?
Why do you feel like you don't feel uncomfortable at all? "

"When I look at you, little guy, why should I feel uncomfortable?" Huangfulan said lightly, "As you just said several times, how can you, little guy, make trouble?
I can treat you to death with just one hand, and you won’t be able to move at all! "

"Auntie, you are looking down on me."

"I'm just stating that I'm a lustful little guy but can't do anything about it." Huangfulan smiled.

Xu You has black lines all over his head, what a shame and humiliation!

To be looked down upon like this!The damn thing is that I really can't refute even one point.

"Let's get started, little one. I want to see what new theories you can come up with."

Xu You took a deep breath, didn't hesitate, and grabbed Huangfulan's slender hand.

He rubbed each other's green jade fingers one by one. They felt very good, with a skeletal beauty and a gentle and delicate beauty.

It is a pleasure to hold such fingers, of course, the meticulous service is still there.

Gently pull and rub your fingers until the bones snap.

Huangfulan didn't hesitate either. Her charming eyes curiously looked at Xu You's side face with a serious face, watching him playing with his fingers seriously.

At this moment, through direct intuition, I realized that Xu You was really serving him seriously.

Looking at Xu You, who was full of youthful aura, and looking at his handsome profile, the aunt's eyes began to follow him involuntarily.

She finally found that she really liked this little guy more and more, and everything about him was touching her heart.

"Auntie, I'm going to massage your lower abdomen." Xu You said.

"alright."

"Why are you staring at me?" Xu You asked strangely when he looked up and saw Huangfulan staring at him.

"Who told you, little guy, that you are so good-looking and you don't want to show it to your aunt?" Huangfulan rolled her eyes slightly.

"Look, you can look or touch whatever you want." Xu You smiled playfully.

Then he directly placed his hands on Huangfulan's lower abdomen.

hiss!
Xu You took a breath. He knew that his aunt's belly should be very warm, but he didn't expect it to feel so warm.

Such a flat and delicate lower abdomen is called a lower abdomen!
"奀~~"

The moment she put her hands up, Huangfulan couldn't help but make a nasal noise. She seemed to have underestimated the magic power of Xu You's big hands!

This was the first time a man put his hand on his belly, and the temperature in his palm had extremely terrifying penetrating power.

Huangfulan's whole body tightened involuntarily again, and at the same time, her face became flushed at an extremely fast speed.

"Auntie, are you okay?" Xu You was stunned for a moment when he saw Huangfulan's reaction.

"It's okay." Huangfulan took a deep breath, "Just do what you want."

"Okay." Xu You began to massage slowly and clockwise, and then whispered softly, "Auntie, I told you just now, this lower abdomen is the foundation of a woman.

There is a lot of knowledge in how to nourish the lower abdomen.I now have a technique called Immortal Abdominal Rubbing.

This health-preserving technique is very good. Regular practice can nourish the skin and detoxify, and the effect is very good. "

"Hmm..." Huangfulan hummed perfunctorily. Her ability to remain calm was the result of forced suppression.

As Xu You's abdominal rubbing techniques progressed, she was now in a very mysterious situation, as if she couldn't even feel her breathing.

The whole person felt like an immortal, with an itching feeling in the seams of his bones.

This immortal belly rub has such terrifying power. Now if I ask her to stand up.The kind where she didn't even have the strength to stand up.

"Auntie, come and let me teach you."

At this time, Xu You took Huangfulan's hand and pressed her hand on her belly. Then he controlled her hand and began to continue walking.

Huangfulan's thoughts slowly came back. It was fine if she pressed herself, not as exaggerated as before.

huh~~
Huangfulan slowly adjusted her emotions in her heart, feeling Xu You's big hand wrapped around her own and pushing and rubbing.

"Auntie, please write down these actions and press them yourself if you have nothing to do before going to bed." Xu You said seriously.

"Yeah, okay." Huangfulan nodded slightly.

"How do you feel now? Do you feel warm in your lower abdomen and warm all over?" Xu Youxiao asked.

"Indeed, your method is indeed feasible."

"right."

Xu You let go of his hand with some satisfaction, and then pressed Huangfulan's thigh directly when she was defenseless.

"Ah!" Huangfulan was startled and her body tensed up again, "What are you doing!"

"Help Auntie press her legs. Auntie, you can rub your abdomen yourself, and I will cooperate with you by pressing your legs. This will have a better effect."

Huangfulan's expression was stagnant, but she couldn't refuse, but the pressing of her legs really hurt her even more.Damn it, now I can only continue to resist.

Xu You's technique was more sophisticated than when he pressed his legs from behind just now.

With each massage, her heart skipped a beat, and then her own techniques became messy, and she didn't know what she was pushing randomly.

In this way, after a few quarters of an hour, Xu You stopped and looked at Huangfulan, "Auntie, how are you now?"

"Hmm, not bad, not bad." The distracted Huangfulan nodded casually.

"Eh? Auntie, why are your lips so sweaty?" Xu You looked at Huangfulan's lips and felt a little strange.

He moved up a little, sat beside Huangfulan's arm, then put his hand on Huangfulan's red lips, slightly wiping away the glitter.

At this time, Huangfulan subconsciously bit Xu You's index finger.

Xu You was stunned for a moment, and Huangfulan who woke up was also stunned for a moment. They both looked at each other in astonishment.

Xu You looked at the sharp contrast between Huangfulan's own index finger and Huangfulan's red lips, and was stunned when he saw his aunt's charming eyes and fair skin with blush.

The atmosphere became extremely weird at that time.

For Xu You, this massage service that lasted for more than an hour could be said to have suppressed his feelings for Huangfulan.

But it seems like I can’t hold it back at this moment!

Huangfulan under the dim light has an indescribable charm, and Xu You's affection is erupting like a volcano.

The same is true for Huangfulan. She has been suppressing her emotions for more than an hour.

Even the extent of her suppression was much greater than that of Xu You.

As we all know, when things go to extremes, they will inevitably reverse. The harder things are suppressed, the harder they will rebound.

The two of them are now facing such a situation, and their love for each other comes back overwhelmingly at this moment because of this opportunity.

"Aunt."

Xu You shouted with trembling in his voice, and Huangfulan looked at the hot volcano-like gaze in Xu You's eyes. The hot gaze even made her dare not open her eyes.

Xu You subconsciously moved closer slowly.

"No!" Huangfulan's remaining sense told her not to do this.

"Auntie, I. I want to kiss you!" Xu You directly hit a straight shot at this moment, not caring about much else.

"No, we can't do this! This won't work." Huangfulan continued to shake her head, but her voice and tone of rejection were so feeble.

Xu You couldn't care less at this moment, so he dunked on the ball as fast as thunder.

A precise kiss was placed on Huangfulan's lips.

Faced with Xu You's offensive, Huangfulan, who had extraordinary cultivation, did not react at all. She was easily attacked by Xu You like a weak woman.

In other words, she was not thinking about rejecting or resisting to escape at this moment, and her subconscious mind directly made her accept such a ridiculous fact.

"No!" Feeling Xu You's kiss, Huangfulan wanted to push it away.

But at this moment, Xu You had already lost his mind. The sweetness and softness brought by the kiss made his male power explode, and his broad arms had already held Huangfulan in his arms.

With those strong arms and chest, coupled with the weakening of strength during the kiss, Huangfulan now only felt that her whole body was a little weak and a little dizzy.

At this moment, Huangfulan's remaining rational thinking was completely swallowed up.

The emotions that had been suppressed for many years broke out at this moment. She took the initiative to hug Xu You's back tightly and responded enthusiastically to the kiss.

Once a mature woman's heart is moved, it will be like a landslide and a tsunami, overwhelming and gorgeous!
