Time flies, and soon Ye Chen ushered in the summer vacation. After completing the final exam perfectly, Ye Chen devoted himself to the drug research and development work of Chenxi Pharmaceutical established by Cheng Xi.
In just over a month, several health care drugs developed by Ye Chen were submitted for review, and various drugs such as eye-brightening, whitening, breast enhancement and slimming with no side effects were produced one after another.
And Cheng Xi was also busy with the construction of the factory, the laying of the production line, and the recruitment and training of management personnel and grassroots workers.
Naturally, the commonly used drugs in the hospital are also within the business scope of Chenxi Pharmaceutical. Relying on Ye Zi's relationship, in the future, as long as the licensed drugs are obtained, they will all be included in the purchased drugs of Xianghe Hospital.
Under Ye Zi's contact, Liu Qing also joined their team, mainly responsible for the configuration of existing commonly used drugs, as well as the development of Western medicines, which Ye Chen is not good at. Of course, she will also be responsible for the cooperation with Xianghe Medical College to develop new drugs.
"Brother Chen, are you back?" Ye Chen just returned home and heard Cheng Xi's voice coming from the kitchen, "Yeah!"
After many days of contact, the relationship between the few people has become familiar. Not long after, Ye Zi also returned home from get off work, and Cheng Xi just prepared dinner.
"Sister Xi, the formulas of these medicines have been prepared." Basically, the dinner time every night is also the time for them to discuss work.
"Well, the factory building here is basically completed, but the production line is not ready for assembly yet, and the recruitment is still in progress. We can't rest assured about the newly recruited employees. The core formula may still need to be checked by ourselves."
"The problem here is not big. The methods of processing various medicinal materials do not need to be kept secret. The materials of several medicines can be put together, and the final ratio can be checked by our own people."
"Achen, are you done with your work?"
"Yes, if there are no new drugs to be developed, it should be over."
"Then go to school to help Sister Qing. Several people in the doctoral student group she is working with have gone home for the holiday. You can go and help."
"Okay, then I will go to school to find Sister Qing tomorrow."
Ye Chen lowered his head and continued to eat, but he did not notice that Ye Zi and Cheng Xi looked at each other nervously.
...
Early the next morning, Ye Chen packed his simple luggage and went to Xianghe Medical College to join the new drug research and development team.
"Knock, knock." "Sister Qing." Ye Chen knocked on the door of Liu Qing's dormitory and called softly.
"Xiaochen, come in." Soon, Liu Qing opened the door in a light pink home dress. Her face without makeup was still as delicate as a girl, and her not-thin figure and lazy posture showed the charm of a young woman.
In fact, the layout of Liu Qing's dormitory is a bit strange. The small dormitory has two rooms, one large and one small. The small room was originally used by Liu Qing as a study, and now it has been cleaned up for Ye Chen to stay temporarily.
This is because Liu Qing's dormitory was originally connected to the dormitory next door. The owner of the dormitory next door is Liu Qing's ex-husband Gao Bo. Now that the two have divorced, it would be a bit strange to fill the opened place again.
The morning sun shone in from the small window. Liu Qing leaned against the door and looked at Ye Chen who was packing up neatly and said, "Xiao Chen, you have to stay here for a few days."
"It's okay. Sister Qing's place is so tidy. How can you feel wronged? What's more, you can eat the food made by Sister Qing. It's a blessing."
"Haha, you are so sweet." Liu Qing smiled and said, "Then sister will prepare lunch for you. After eating, go to the laboratory."
"Okay!"
After eating, the two came to the laboratory to join the intense research and development work.
"Knock knock." There was a knock at the door. Ye Chen, who was closest to the door, stood up and opened the door.
"Who are you looking for?" Outside the door was a short young man who looked about 20 years old, about the same age as Ye Chen. But he was wearing a worn-out work jacket and his pants were a bit dirty and old, which was out of place on the university campus.
"I'm looking for Liu Qing. Is she here?"
Looking at the short and dark young man in front of him, Ye Chen couldn't help but frowned, turned around and shouted, "Sister Qing, someone is looking for you."
"Get out of the way, let me in!" The young man said and tried to push Ye Chen away and walked inside.
"Don't move! You are not allowed to come in here." Ye Chen was afraid that the young man would rush in and break something, so he pushed him outside the door with one hand.
As if he didn't expect Ye Chen to be so strong, the young man also calmed down, but there was a hint of hatred in his eyes.
Liu Qing frowned and said unnaturally, "Gao Wei? What are you doing here?"
"Sister-in-law, my brother asked me to come to Zhonghai."
It turned out that the young man was Gao Wei, the younger brother of Liu Qing's ex-husband Gao Bo. Both were born in poor mountainous areas. The elder brother Gao Bo had excellent academic performance since childhood and was admitted to university, while the younger brother grew up in his hometown. He did not continue to go to school after graduating from elementary school, and he worked in the fields and herded cattle every day.
"I am not your sister-in-law anymore! Did your brother ask you to come to me?"
"No, I came by myself. I have something to tell my sister-in-law."
"What is it?"
Gao Wei looked at Ye Chen with his thief eyes and said nothing.
"Xiaochen, you go in first, it's okay."
"Okay."
After closing the door, Ye Chen heard Liu Qing walking farther and farther in high heels, and he followed her with some concern.
Beside the half-open fire escape door, Ye Chen heard the voices of the two.
"Sister-in-law, I found this in my brother's room."
"What is it?"
"Don't you know what it is?"
"Huh." Liu Qing took a long breath and lowered her voice and said, "What do you want!"
"Sister-in-law and my brother have been divorced for several years, and I miss you so much."
"Don't say such disgusting words!"
"Hehe." Just listening to this laughter, Ye Chen could imagine Gao Wei's obscene eyes. "Sister-in-law works here, the salary is not low, give me 20,000 yuan to spend."
"Okay! Get out of here after taking the money, don't let me see you again!" Liu Qing's voice was full of anger.
"No, sister-in-law, do it to me again tonight."
"Don't even think about it!"
"Then I'll post these photos on the wall tomorrow!"
The two seemed to be in a stalemate, and Ye Chen was still thinking about whether to rush over to help, but how to deal with the photos in Gao Wei's hands, what if he still has archived them.
"Just once, you give me everything." Liu Qing suppressed her anger and said helplessly.
"I keep my word."
Feeling that the conversation between the two was about to end, Ye Chen hurriedly walked back to the laboratory quietly.
Everyone was still busy at their desks, but no one paid special attention to the two people leaving.
"Sister Qing, are you okay?" After Liu Qing came back, Ye Chen immediately greeted her and asked, as if he knew nothing.
"It's okay, continue to work."
Seeing that Liu Qing kept silent, Ye Chen didn't know how to talk about it. Time passed quickly and it was soon time to get off work.
Liu Qing went out to buy vegetables and came back to cook dinner. The two people, who were each thinking about something, had almost no words, and Liu Qing didn't seem to notice Ye Chen's abnormality.
After saying good night to each other, the two returned to their rooms. Ye Chen lay on the bed tossing and turning, unable to fall asleep.
"Xiaochen." Liu Qing's voice suddenly came from outside the door. Ye Chen lay on the bed with his eyes closed and did not respond.
"Xiaochen, are you asleep?"
Ye Chen felt sad, but if he answered, there would be unpredictable consequences.
"Hey." There was only a slight sigh outside the door, and the footsteps went away.
Ye Chen, lying on the bed, looked at the ceiling, imagining the small black body pressing on Sister Qing during the day, and the picture in his mind could not be dispelled for a while.
"Bang." A light sound suddenly came from behind the small bed, and the white wall dust fell to the ground, revealing a small hole.
"No." Ye Chen put his ear to the wall and vaguely heard Liu Qing's voice.
It turned out that when the wall was separated, in order to save some expenses, he only found an unskilled worker to build the wall and apply the plaster. Now Liu Qing was pressed against the wall by Gao Wei, and the wall dust fell to the ground.
Ye Chen trembled as he approached the hole and saw the next room.
"Uh, no." In the quiet room, Liu Qing's voice became somewhat clear.
Ye Chen gradually became familiar with the light and saw the scene next door clearly. He could see a dirty hand moving in the flesh-colored underwear in front of him.
"No, Sister Qing's lower body was actually being played with by that little gangster from the countryside!" Ye Chen shouted in his heart, but he couldn't control himself from staring at it, nor could he control his cock from sticking up high.
"Sister-in-law has so much slutty water." "Uh, ah." "I haven't touched such a tender flesh hole for a long time."
Gao Wei kept saying obscene words, while Liu Qing kept making meaningless moans.
"Baji." "Woo, no."
Gao Wei seemed to be licking Liu Qing's breasts, making obscene saliva sounds.
"This, is so big!?" Following the voice, Ye Chen looked upwards as much as he could. Between Liu Qing's opened pajamas, a huge bra was hanging on one side. Gao Wei's rat-like head was almost completely buried in the huge breasts which were estimated to be a G cup.
Spitting out the nipple in his mouth, Gao Wei kneaded the breast that he couldn't control at all with one hand, saying: "Sister-in-law's big breasts are still so soft, like dough, and fragrant."
After that, Gao Wei continued to use his hands and mouth to play with Liu Qing's breasts and vagina. Gradually, Liu Qing also felt it, her neck raised high, and the moaning sound in her mouth gradually became uncontrollable.
"Well, ah, ah!" Ye Chen could see her slender thighs trembling with the climax moan, and her body slowly collapsed with some powerlessness.
"Sister-in-law has so much water, much more than those old widows in our village!" Gao Wei pulled his hand out of Liu Qing's underwear, and his middle finger and index finger looked crystal clear under the white light.
"Suck my cock, sister-in-law!" Gao Wei took off his only shorts, and a huge cock that was completely inconsistent with his short height jumped out.
The nearly 20-centimeter penis stood straight in front of Liu Qing's eyes. The long foreskin was not cut off, and the folds were at the bottom of the glans, which looked extremely obscene. Some transparent liquid also seeped out from the urethra at the top of the glans, and Ye Chen could feel the fishy smell through a wall.
There was still a trace of resistance in Liu Qing's eyes, but she still resigned herself to opening her mouth.
"Ah! How can I!" Watching the huge penis sink into Sister Qing's mouth little by little, Ye Chen clenched his fists tightly as if to vent. But the penis in his lower body could not help but become hard with blood, even so, his penis was only half the length of the giant penis.
"Sister-in-law is sucking my cock, ah! It feels so good." Liu Qing gently supported Gao Wei's waist with both hands, and her head moved back and forth slowly. The side profile of that intellectual beauty and the vulgar and dirty penis looked particularly strange.
Gao Wei pulled a chair over and sat down, and continued to play with Liu Qing's breasts with his hands.
"Ah." Liu Qing's face gradually turned red, and she whimpered in her mouth stretched open by the cock. Ye Chen looked carefully and found that Liu Qing's little hand had actually reached under him, gently rubbing his pussy through his panties, and the already thin panties were already soaked.
"Ah!" After a while, Gao Wei suddenly screamed, stretched his hands up and firmly grasped Liu Qing's jade head, slightly bent his body, and began to exert force with his thin but strong waist, and the shiny cock quickly thrust in and out of Liu Qing's mouth.
"Woo woo!" Feeling a little uncomfortable, Liu Qing tried to push Gao Wei away with both hands, but how could she, who was so weak, do so? Instead, it made Gao Wei even more excited.
"Ah, sister-in-law! Take my cock in, ah!" Gao Wei's cock went deeper and deeper, gradually filling Liu Qing's mouth.
Gao Wei thrust hard into Liu Qing's mouth without mercy. The lewd fluid from the penis and the saliva from her mouth stuck together and slowly flowed down along the corners of her mouth.
Ye Chen's hand subconsciously reached into the loose pants and stroked the hard but thin penis.
"Oh! I'm going to cum! Ah, sister-in-law will cum for you!"
Gao Wei pulled his penis out of Liu Qing's mouth, stretched out his hand and started stroking it quickly, and the red glans pointed directly at Liu Qing's cheek.
"Is Sister Qing going to be facial-cummed!?" "Ah!" Ye Chen's heart tightened, and he heard Gao Wei's scream.
A stream of thick yellow semen shot directly onto Liu Qing's nose, and instantly spread and splashed all over her cheek. At the same time, the penis in Ye Chen's hand also jumped and flowed out thin semen.
Ye Chen came back to his senses and looked through the small hole again, only to see that Liu Qing's face was already covered with semen, flowing down her neck.
What shocked him was that Gao Wei's penis was still so hard, with no sign of softening. Gao Wei was so anxious that he carried Liu Qing to the bed, and his rough hands pulled off the wet panties.
"Sister-in-law, I'm going to fuck your pussy!" Liu Qing didn't answer, but turned her head to the side, letting Gao Wei stand by the bed, holding her straight legs up, and the hot penis was directly against her wet pussy.
"Oh, sister-in-law's pussy is so juicy, it's much more comfortable than fucking those widows in the village!" Gao Wei, who has been doing farm work in the countryside for many years, was tanned a little, and his rough skin was in sharp contrast with Liu Qing's delicate skin.
"Sister Qing!" Ye Chen stared at the junction of the two people and murmured. The penis in the lower body became hard again, but it was a little painful.
Liu Qing's head tilted to one side, her beautiful eyes were closed, but her gradually flushed face proved that she was not unresponsive.
Gao Wei did not know any skills, nor did he have any thoughts of sympathy for women. He just held Liu Qing's ass and fucked her hard. But it was this kind of thrusting like a pile driver, coupled with the majestic penis and strong body, that made Liu Qing, who had been lonely for a long time, unable to resist.
"Xiao Wei, go slower, or I can't do it anymore." Liu Qing, who was approaching climax, spoke in a soft and charming voice, which was completely different from her usual gentle and elegant voice.
"Sister-in-law, I'm about to cum!" Gao Wei said, stepping one foot on the bed, and thrusting his penis more vigorously from top to bottom.
"Don't, don't cum inside." Liu Qing said softly. Gao Wei didn't say anything and continued to thrust vigorously.
"I shouldn't be able to give Sister Qing such sexual happiness!" The lewd intercourse scene deeply stimulated Ye Chen's heart. He looked a little depressed, but his penis was not at all.
"Sister-in-law, I'm going to cum!" "No, no! You can't cum inside!" "Ah!"
"Sister Qing, was you, cummed inside?" Ye Chen thought to himself, and semen flowed out of his penis.
"Ah, ah!" Gao Wei shouted angrily and continued to thrust. The yellow semen and transparent vaginal fluid kept seeping out of the junction of the two people with the thrusting.
"No, no!" Liu Qing resisted with her mouth, but her body still reached the peak of climax, and her body trembled under Gao Wei.
"Isn't my sister-in-law a chicken that can't lay eggs? It doesn't matter if I do it inside." Gao Wei was also a little tired. He climbed up from Liu Qing, walked to the side, poured a glass of water and drank it, saying: "My brother has borrowed my seed for more than two years, and my sister-in-law hasn't been pregnant by me, but I have made several girls pregnant outside."
Liu Qing didn't say anything. She lay on the bed with her legs apart, and put her jade hand into her vagina to dig. A stream of thick yellow and white semen flowed out of the vagina, which looked very obscene.
"Sister Qing was actually ejaculated so much!" Watching the semen being dug out of the vagina little by little, a lot of semen was stained on the originally neat pubic hair, making the whole lower body covered with semen, and more semen flowed in front of her to form a small semen pool,
"It's as you wish, I hope you keep your word." After cleaning up, Liu Qing sorted out her clothes, stood up and walked out.
Gao Wei stood up and blocked Liu Qing's way and said, "Sister-in-law, I'm not done yet." His cock, which had softened a little, became hard again, and there was no sign of fatigue at all.
"Then I won't either, oooh!" Gao Wei didn't listen to Liu Qing's words. He pulled and pushed Liu Qing, whose legs were sore, onto the bed.
Gao Wei pulled the loose pajamas aside. The wet underwear had no protective effect in front of him, so he pulled it off and threw it aside. He grabbed Liu Qing's plump buttocks with both hands and spread them apart, and saw the pink valley.
"Oh!" The posture from behind seemed to be deeper. As soon as Gao Wei entered Liu Qing, she screamed. Gao Wei grabbed Liu Qing's long hair roughly and thrust his lower body hard.
"Hoo, hoo, oh!" Ye Chen suddenly woke up from his sleep. He had fallen asleep without realizing it.
"No, no way." There was a ray of light coming from the hole. He turned on his phone and saw that it was already two o'clock in the morning, and Liu Qing went out at less than ten o'clock.
Sure enough, the intercourse between the two people next door had not yet ended. Liu Qing was naked, with her hands supporting the wall in front of Ye Chen, and her legs spread wide open, so that Gao Wei, who was half a head shorter than her, could reach her vagina.
"Ah, sister-in-law's flesh hole is so good to fuck, no matter how hard you fuck it, you never get tired of it." Gao Wei stretched out his hands from under her body and grabbed the huge breasts that were shaking with the thrusting, "These big breasts are so soft!"
"Ah, Xiaowei, I can't take it anymore, sister-in-law is going to come again!" Ye Chen's angle was just right to see Liu Qing's face covered with yellow and white sperm stains and dense beads of sweat, plus the huge breasts being kneaded and the small hole being thrusted by the huge cock, and the cock instantly stood up again.
"Oh, ah! I'm coming!" Liu Qing's legs trembled, and countless obscene liquids flowed out of the junction of the two.
Liu Qing knelt on the ground with powerlessness, and the hideous cock left her body. The white liquid in the slightly swollen small hole was slowly flowing out, and it was unknown how many times it had been shot inside.
"Sister-in-law!" Gao Wei's hoarse voice came.
"Xiaowei, let sister-in-law take a rest, you sit down first." Gao Wei sat down as he said, with his legs spread wide apart, and the ferocious cock under his crotch raised high.
Liu Qing propped herself up and slowly crawled towards Gao Wei, with her raised buttocks facing Ye Chen. In the small hole that had not yet closed, traces of white turbidity could still be seen.
Liu Qing knelt in front of Gao Wei, propped up her breasts with both hands, and actually gave Gao Wei a titjob. The plump breasts wrapped the entire cock in them. While moving up and down, Liu Qing would occasionally extend her tongue to lick the glans.
"Oh! Sister-in-law's breasts are so comfortable!" Gao Wei had never enjoyed such a scene before. He propped his hands behind his back, closed his eyes and exclaimed: "And the mouth, sister-in-law makes me so comfortable!"
"Qing, why would sister Qing give him a titjob!" Ye Chen's heart suddenly hurt, but almost instantly, a strange pleasure appeared in his body.
After an unknown amount of time, Gao Wei suddenly stood up and pushed Liu Qing to the ground, "No more! Sister-in-law! I want to fuck you!" He pressed down on Liu Qing, grabbed her breasts with both hands and continued to thrust.
"Xiaowei, sister-in-law really can't take it anymore, hurry up." "Okay, sister-in-law, watch out!"
Gao Wei increased his speed, thrusting in and out like a pile driver, pulling out the thick and long penis until only the glans was left, and then thrusting it in again until it reached the center of the flower.
"No, no, ah, ah!" Liu Qing exclaimed, but couldn't utter a complete sentence. After being fucked quickly a few times, Liu Qing's hands involuntarily wrapped around Gao Wei's neck, and her legs were wrapped around his waist.
"Oh! Sister-in-law, I'm going to cum!" "Ah, I, I'm going to cum too!"
Gao Wei was still thrusting quickly, but Ye Chen found that Liu Qing was also thrusting her willow waist to cooperate with Gao Wei's movements!
"Ah...!" Liu Qing let out a long and seductive moan, her neck raised high, just in time for Ye Chen to see her lewd expression when she climaxed.
The moist little hole made Gao Wei more excited, and he sped up his movements, saying, "Ah, I'm going to cum, sister-in-law!"
"Ah! I'm cumming!" With more than a dozen strong thrusts, Gao Wei's semen was all shot into Liu Qing's little hole.
Liu Qing collapsed on the ground with weakness, twitching from time to time.
"Sister-in-law, I keep my word, I'll take the money, and I'll return all the things to you! You can go." Gao Wei took out a CD from the cabinet, put it on the table beside him, and put away the 20,000 yuan that Liu Qing brought on the table and said.
Liu Qing sat up slowly, put on her clothes slowly, and limped out of the room.
Ye Chen, who had ejaculated at some point, quickly found a piece of paper to plug the hole, and lay on the bed pretending to sleep. He only heard Liu Qing gently open the door and enter the dormitory, and then went to the bathroom. Then, Ye Chen fell asleep in a daze.
"Xiaochen, get up!" The gentle voice outside the door woke Ye Chen up, and he quickly replied: "Okay, Sister Qing, get up right away!"
"I prepared sandwiches and milk for you in the morning, so hurry up and wash up and get ready to eat!"
Hearing that there was no abnormality in Liu Qing's voice, Ye Chen seemed to wonder if what happened last night was a dream.
"Hmm?" Ye Chen, who was brushing his teeth, suddenly smelled a strange smell, and following the smell, Ye Chen looked at the dirty clothes basket next to the washing machine.
After brushing his teeth and rinsing his mouth, Ye Chen couldn't help but look over and saw that the flesh-colored bra, panties and pajamas that Liu Qing wore yesterday were lying on top of the dirty clothes basket, and the fishy smell came from here.
The yellow-white mixture of semen covered the entire underwear, and a whole solidified object could be seen inside the underwear. I really don't know how much semen flowed out of the vagina and stained it.
Ye Chen, who didn't dare to delay for too long, quickly came out of the toilet.
Liu Qing was wearing a loose home dress, with a long and smooth hair draped on one side, and her face without makeup looked very delicate. The lazy temperament and intellectual beauty made Ye Chen exclaimed: "Sister Qing, you are so beautiful!"
Liu Qing chuckled and said: "Haha, your sweet words, you should save them to coax little girls, why coax your sister." Although she said this, the joy on her face was not less at all.
Liu Qing, who had finished breakfast early, rested her chin on her hand and looked at Ye Chen quietly. Seeing that Ye Chen had also finished eating, Liu Qing put the cups and plates together and walked to the kitchen.
"Sister Qing, you are not feeling well, let me help you!" Seeing that Liu Qing's steps were a little staggering, Ye Chen quickly stood up and supported her.
"Then you come, sister is fine, go change clothes and prepare to go to the laboratory." Liu Qing said with a gentle smile.
After they packed up, they went out together. Liu Qing seemed to be in a good mood, probably because the trouble yesterday was over. Ye Chen, who gently supported Liu Qing and walked slowly, thought so, but for some reason, he felt a little regretful in his heart.
