i have a chromosome want to meet you

Song Yu's roommate was said to be an intern in the hospital and would not return to the dormitory all day, and Chu Xiuyuan learned that he was even more presumptuous.

A bottle of lubricating fluid in each hand: "How many bottles do we use today?" Three out of five can't be used, two out of five can always be used...

Song Yu smiled: "For the first time, how many bottles do you want to use?"

Chu Xiuyuan gave him a disgusted look: "Don't be bad..."

Hehe, can't I? "I was afraid you would get hurt."

Chu Xiuyuan vowed: "What are you afraid of? My blooming daisy has the same composition as the diamond, and it is strong. If you can't, then replace it with me, and let you taste my world-renowned male dog waist."

Song Yu chuckled and said, "The components of graphite and diamond are the same, so be more cautious for the first time."

"I can see it." Thinking of last Friday when he took off his trousers, really took off his trousers, but failed to do anything, Chu Xiuyuan felt a little resentful, "You are the kind of me who took off my trousers, you I can't find the type of flowers either."

Song Yu kissed the corner of Chu Xiuyuan's mouth: "It seems that if I don't find some flowers today, you won't be satisfied."

Assuming you know it well, Chu Xiuyuan hummed a few times and grabbed the set of bowel cleansing tools: "I'll go wash it."

"do you need my help?"

"roll."

According to the instructions, I took a thermos of warm water that Song Yu had prepared, rubbed it secretly and shut it in the bathroom cubicle. After more than half an hour of tossing, I finally cleaned myself up. When I opened the cubicle door, my legs were numb. up.Seeing Song Yu standing at the door, his legs gave way and he fell directly into Song Yu's arms.

Seeing that no one was around, she hugged Song Yu and acted like a baby: "I'm so exhausted, I don't even want to do it anymore."

Song Yu smiled: "I'll carry you back?"

"Don't, don't, don't..." Chu Xiuyuan's legs were so numb that he was crawling with a hundred thousand ants, and the numbness became even worse when he touched it slightly, and the ants burrowed straight into the soles of his feet and bones.

After a while, he wanted Song Yu to drive him out, but in the public bathroom, after thinking about it, he kept a low profile, limped and walked back to the dormitory alone.

Climbed onto the bed with shaking legs, lay on the bed with a long sigh and remained still, pouted his mouth, and pretended to be dead.

Song Yu's heart melted when Chu Xiuyuan pouted, and he carefully pinched Chu Xiuyuan's thigh and calf, which made Chu Xiuyuan howl.After pinching for a minute or so, the numbness completely passed.

Chu Xiuyuan couldn't bear it as soon as he was good. He was lying on the inner side against the wall, on a single bed, and the space was very small. Stretching out his flexible toes, he went to pull Song Yu's zipper, and the pressure and friction tried to pull the zipper open, so that Song Yu's breathing became rough by two minutes.Chu Xiuyuan took the initiative to get angry, who could bear it.Grabbing Chu Xiuyuan's naughty ankle, leaning over to kiss him.

"Fun?"

"Hmm..." Chu Xiuyuan opened his mouth to greet him, and the air was filled with the sound of muddy water.

The two of them kissed so passionately, the thunder from the sky stirred the ground, and Song Yu's tongue was so nimble that he swept across all the sensitive spots in Chu Xiuyuan's mouth without missing a single one.Chu Xiuyuan likes Song Yu's powerful tongue leading him to stir together, likes Song Yu eagerly licking his sensitive upper jaw, and even more like Song Yu's sucking, every time he fiddles and sucks with the tip of his tongue, there is a current spreading to the scalp.

"Hmm..." Chu Xiuyuan hugged the back of Song Yu's neck tightly, and his legs hooked Song Yu's back uncontrollably. It was so comfortable that the suction made his waist go soft.Qi and blood churned, and all the cells in his body were instantly occupied by the desire to burn fire.

And Song Yu took advantage of his leg lift and took off his sweatpants.

Chu Xiuyuan took off his pants in cooperation, and laughed: "Do you know how to do it?"

Song Yu said seriously: "I have studied the strategy for three days."

"Pfft..." After three days of researching the strategies, "You should be playing games. Should you understand this kind of thing instinctively?" What is done on paper is superficial, but I never know that this matter has to be practiced.To put it bluntly, what kind of messy strategy is piling.

Of course Song Yu didn't agree, he didn't want Chu Xiuyuan to get hurt a little bit because of this, so he had to keep all precautions in mind: "Don't say it so easily, these instincts alone won't work."

"Why doesn't it work? Isn't there a lot of novels about attacking and defending Shuangjie, those No. [-]s are all talented, like they have done it a hundred and eighty times, they can make those No. [-]s want to die for the first time, and since then I only have you without him in my heart. The skill points are all full."

Can novels be believed?Do you think such people really exist in reality?Song Yu frowned and wanted to refute, but saw Chu Xiuyuan's playful eyes and the corners of his mouth, clearly teasing.

Chu Xiuyuan: "If you can't do it, replace me."

It turns out that the real purpose is here.

Song Yu raised his eyebrows, provocative and confident: "You come."

Chu Xiuyuan didn't expect Song Yu to be so straightforward. Although he could hear the joke in Song Yu's tone, he couldn't miss the opportunity. He pushed Song Yu down and sat on him.

But it's really on the top, and I don't know where to start. It's easy to say but hard to do. The most important thing is that Song Yu didn't cleanse the bowels!What if I go in and bring out a piece of shit?

Chu Xiuyuan: "..."

Chu Xiuyuan, who was disgusted by his own brain, forced a smile, no wonder Song Yu was confident: "I thought about it, I want to be a person who keeps my word."

As soon as he finished speaking, Chu Xiuyuan was so startled that his legs hooked tightly around Song Yu's back. When he realized it again, Song Yu had already thrown him under him, with his legs hanging on Song Yu's arms.

Opening damiana, Song Yu softly, comfortingly and guidingly: "Relax..."

Chu Xiuyuan exhaled, suddenly, "Hmm..."

……

According to the strategy, one should get used to it for a while, and then find the key points to relax. As a result, Song Yu was not proficient in business, and finally waited for Chu Xiuyuan to adapt, but he couldn't find it after searching for a long time.

"Can you do it..." Chu Xiuyuan frowned, "Isn't it that difficult to find a needle in a haystack?" In order to wait for Chu Xiuyuan to adapt, it took a lot of time. In fact, it took less than half a minute to explore, but Chu Xiu Yuan was in a state of anxiety, his whole body was covered in fire, and Song Yu's majesty was constantly showing his strength and upright figure under Chu Xiuyuan's nose, which made Chu Xiuyuan's heart itch unbearably, and he always felt that it had been a long time.

"Can you find it?" Chu Xiuyuan asked.

Song Yu said patiently, "Don't worry."

Chu Xiuyuan propped up his upper body, stretched out his hand to call Song Yu: "Aren't you in a hurry now?"

Song Yu clenched his teeth from being rubbed, and squeezed out a sentence with his masseter muscles: "Don't make trouble, you will get hurt."

Chu Xiuyuan was in a hurry: "I won't say so."

"But I'm big..."

Chu Xiuyuan: "..."

"Preparation must be in place."

Chu Xiuyuan copied the pillow behind his back and smashed Song Yu, I will make you grow up so big, let you grow up so big!

After the smashing, a flash of inspiration suddenly dawned on him. He kicked Song Yu away, turned sideways, leaned his upper body out of the edge of the bed, quickly pulled out two books from the bookshelf under the bed, spread them out, and placed them in front of Song Yu.

"Medical school, there must be some advantages."

Song Yu took a look and found a book called "Diagnostics". On the opened page was written: Anterior palpation.

"Located below the urine storage organ, about 2cm behind the pubic symphysis, shaped like a slightly flattened chestnut... Use the index finger to gently massage, then slowly extend to the third sacral vertebrae and continue to the deep part of the sigmoid colon for inspection. The inspection sequence is as follows: Ahead..." *Diagnostics

Before it was over, Chu Xiuyuan raised his eyebrows triumphantly, and threw the book to Song Yu again: "It's better to eat with this."

Song Yu turned his head to look, "It is an unpaired substantial organ, composed of glandular tissue and smooth muscle, and its surface is covered with a fascial sheath... It is located between the urine storage organ and the diaphragm. Its bottom is adjacent to... …behind it is the intestinal ampulla of the 3rd sacral vertebra continuing to the sigmoid colon. It can be palpated behind when hemorrhoids are digitally examined, and the ampulla of the conveying tube and… can also be palpated upward.”

There are also two sagittal and horizontal slices at the back. To put it crudely, they are anatomical sections.

It turned out to be an "Anatomy".

Song Yu: "..."

Sure enough, it is very advantageous... The description is very clear, and it is accompanied by detailed explanations with pictures. It is short of a video teaching on how to dissect and make specimens.

Song Yu twisted the corner of Chu Xiuyuan's proud mouth: "I lost to you."

He glanced at the cross-section again, wrinkled his nose and threw both books out.

Chu Xiuyuan chuckled, and was suddenly pushed back on the bed by Song Yu to continue.

"Scholar, you can't do it."

"Have you studied diagnostics well?"

"You are a fake academic master."

"Your A+ in the anatomy stage must be a lie."

Chu Xiuyuan was addicted to teasing, Song Yu just smiled and wiped away the broken hair on his forehead with one hand.

"Ah..." Ten seconds later, Chu Xiuyuan's voice suddenly changed.

Song Yu exhaled: "I found it?" After asking, he grinded again.

"Looking for... um..." Chu Xiuyuan narrowed his eyes suddenly, feeling sore and swollen with a little itchiness that he had never experienced before, which made his legs and lower back feel strange suddenly.

"Is it comfortable?" Song Yu pressed it again.

"It's... a bit strange..."

"Is it comfortable?" Song Yu asked persistently.

"Comfortable, comfortable..."

"How comfortable is it?"

Chu Xiuyuan touched the back of Song Yu's neck and kissed him. After the kiss, he licked his lips and said, "Sour and refreshing, like old altar pickled cabbage noodles."

"Hmm..." Chu Xiuyuan suddenly took a breath, "Hey, you..."

Song Yu narrowed his eyes and laughed out loud: "I'm still thinking about sauerkraut noodles at this moment, it seems that I didn't serve the family well."

Song Yu became so ruthless that he couldn't stop Chu Xiuyuan from humming sweetly, and Song Yu's ears were so swollen and painful with his gorgeous voice.The breathing was very heavy, with extreme forbearance, and with a lot of concentration, he could barely control himself: "Now, have I served home yet?"

"Ah..." Chu Xiuyuan grabbed Song Yu's shoulder with red marks, and what he said made Song Yu completely burned, "Not enough..."

"not enough?"

"not enough……"

With the invitation and acting like a baby, Song Yu's rationality cracked at the root, but Chu Xiuyuan kept saying, "Song Yu, I want to be filled by you."

The author has something to say: *[Note] There is also anatomy.The original text is excerpted from page 183 of "Diagnostics", which has been partially deleted due to various reasons

Chu Xiuyuan: Why is it that others can make shou cry for the first time, but you can't do anything for the first time, and you still have to watch the three-day strategy?

Song Yu: The varieties are different
