(The second update arrives, ask for support!) ）

"Why don't Xiaoya help you with her mouth!" As she spoke, Xiaoya knelt down in front of Tang Zheng and looked at Tang Zheng pitifully.

Tang Zheng nodded with satisfaction, for men, when doing that, the small mouth above the woman is no less attractive than the small mouth below, and because he was too excited, Tang Zheng's little brother also jumped twice in Xiao Ya's white and tender little hands, as if it had become a little thicker again.

Xiao Ya stretched out the tip of her tongue, as if tentatively licking the tip of Tang Zheng's little mushroom head, and Tang Zheng immediately felt a crispy and numb feeling.

Then, Xiao Ya opened her ruddy little mouth and swallowed the mushroom head whole, the warm and moist feeling immediately made Tang Zheng can't help but snort

Xiao Ya knelt under Tang Zheng and tried her best, sometimes fast and sometimes slow, looking extremely skillful, a trace of saliva flowed out along the corners of her mouth, for Xiao Ya's small mouth, Tang Zheng's big dick was still too thick, so Xiao Ya looked a little hard.

However, Xiao Ya's current expression is also what men like the most, so while being comfortable, Tang Zheng also helped Xiao Ya from time to time to stroke those long hair that hung down as encouragement.

"Ah......h

Tang Zheng let out a dull roar, hugging Xiao Ya's head and not letting her move.

"Woo ......"

Because of Tang Zheng's action, the big guy was pushed up to Xiao Ya's throat, and such a big one, even if there was still a piece exposed, it also filled Xiao Ya's small mouth to the brim, and it could only make such a sound.

After several waves of powerful and powerful jets, Tang Zheng let go of his hand with satisfaction.

"Ahem......"

Xiaoya sat on the ground slumped, her eyes full of tears, and some milky liquid slowly dripped from the corners of her mouth.

"I'm sorry, I can't help it!" Seeing Xiao Ya's aggrieved appearance, Tang Zheng's old face turned red and he said embarrassedly.

"If you like it, master!" Xiao Ya said obediently, she was really choked just now, but looking at Tang Zheng's appearance, it was obvious that Xiao Ya's way of pleasing was extremely useful.

After Xiao Ya stood up, she waved her hand, the water stains on the ground and the remaining white dots at the corners of her mouth disappeared at once, and her whole person returned to the refreshing and bright image she had before, and the clothes on Tang Zheng's body also became neat, as if nothing had happened just now.

As a system assistant, Xiaoya still has this little means.

Tang Zheng was slightly surprised, and asked a little jokingly: "Are you like this, do you want to do it again?" ”

Of course, this is just saying, the real feeling just now has just passed, and Tang Zheng did not recover so quickly.

Xiao Ya said in a coquettish voice: "Master, don't want to take the opportunity to be so bad again, take advantage of the fact that your senses are not so strong during this time, let's continue to practice this "Imperial Maiden Heart Sutra", this time it will be the master's turn to make Xiao Ya comfortable!" ”

Tang Zheng nodded, seeing Xiao Ya's delicate and sensual appearance, if he hadn't ejaculated just now, he would definitely not be able to help but push Xiao Ya down again, at that time, it was not as simple as using the small mouth above, after not being threatened by Corona, Tang Zheng's courage became a lot bigger.

He also wants to know Lu Dao now, what kind of magic is this "Imperial Maiden's Heart Sutra" that can make Xiaoya so respectful.

Xiaoya then said slowly: "There are many sensitive points on a woman's body, in addition to the three sensitive areas on the front chest and below, there are also earlobes, neck, armpits and other places, if the technique is done properly, it can also make a woman's body have a pleasant reaction......"

At this time, Xiao Ya turned into a human physiology teacher, and every time she said a sensitive point, Xiao Ya also stretched out her finger and deliberately pointed it out on her body, which made Tang Zheng feel uneasy several times.

Not only that, Xiaoya also explained in detail the skills and techniques to stimulate these sensitive points, and asked Tang Zheng to operate them himself, and then instructed Tang Zheng on the severity of the strength.

It's just that this thing consumes the exchange value really quickly, and in less than an hour, Tang Zheng's exchange value has been deducted by more than six thousand, so after ending this course, Tang Zheng immediately entered the Fantasy World Realm, wanting to make up for the lost exchange value.

……

"Good husband, why did you come here today even later than yesterday!" Liu Xin'er said with a look of resentment, after breaking through that psychological defense line, Liu Xin'er was especially looking forward to being alone with Tang Zheng, and even the little maid Xiao Ju was also sent outside to guard the door.

"Well, because there are some things that have been delayed, Xin'er has been waiting for a long time." Tang Zheng smiled and grabbed Liu Xin'er's soft twing, and said gently.

"Alright! Xin'er forgave her husband this time, she must come early tomorrow, and it would be best if she could accompany Xin'er all the time. ”

Tang Zheng gently pulled Liu Xin'er into his arms, stroked her beautiful back and said, "There will be that time, I promise!" ”

Tang Zheng has already made up his mind, after the results of this quality inspection exam come down, he must have a good negotiation with Teacher Mao, it is best not to go to class every day, so that he can master the freedom of time much better, and he does not have to go back and forth between the two worlds every day and night like now.

"Well, tell my husband a good news, the list of medicines you handed over to Xin'er a few days ago has been sent over today, and my husband can go and refine those things." Liu Xin'er raised her head and said happily.

"Really? It's great, let's go and see! ”

Tang Zheng has been waiting for these things for several days, and in the past few days, Tang Zheng has brushed up the exchange value and skill proficiency because of the lack of mental power, and all kinds of non-strength, or relying on the ability of super mental arithmetic, in order to maximize the benefits of these mental powers as much as possible, and he can still maintain the exchange value of nearly 10,000 per day.

After upgrading to the Intermediate Pharmaceutical Technique, the upper limit of the exchange value that can be obtained per day has become 8,000 points, and if you count the two 5,000 of the Intermediate Cooking and Intermediate Fishing Skills, Tang Zheng can brush up to 18,000 exchange points a day, and the efficiency can be nearly doubled.

If the types of medicines are complete, then Tang Zheng will be able to refine the awakening liquid, and the problem of insufficient mental power will be solved.

"Purple Heart Grass, Wufang Vine, Gold and Silver Leaf ......" Seeing the precious medicines in the Awakening Liquid formula appearing in front of him in the same way, Tang Zheng was immediately overjoyed.
