Song Yi's room has a large balcony. Looking out from the balcony, you can see the sparse stars in the middle of the night.

Walk in from the door, go straight to the big bed, beside it is the vertical wardrobe, and open it to get the clothes of the four seasons.

Her room layout is very modern, with light colors and a cool temperament, which looks very similar to her.

Song Yi held the nesting basket, opened the door, and saw a cool-looking room, a handsome and bright-looking man staring anxiously at the things in front of him.

He was naked, with smooth arms and waist curves, glowing with a healthy and beautiful luster, and the bitten neck showed her ferocity.

The soft fabric was draped over his body, and the sheets had been changed. Omgea, who had fallen into a fever, had fragile skin, and a slightly rougher fabric would make their skin red and rash.

After Song Yi finished, the first thing he did was to go to the door and bring in the silk long blanket that had been prepared, and hand it to him.

She didn't prepare the soft, soft robe and pajamas for him in advance, so she had to use the long blanket first.

Pei Qingmian took it obediently and covered it from the waist down.

Then the little quail followed behind Song Yi, watching her hold out the things that belonged to her.

The wardrobe was opened, and the underwear she had worn this year was found in the underwear. The soft and beautiful styles made his ears turn red; in the drawer, she found the restraint ring she had been wearing for two years, with her Smell, because the style is old and no longer used, it is only for collection and preservation, and is held by Pei Qingmian in his arms and refuses to let go; at the same time, he takes off the watch that has been worn on his wrist for a long time and puts it on the bed...

There is also a cotton blanket of Song Yi - it has been used for 20 years since she was five or six years old. Because of its commemorative significance, it has never been thrown away. It had been used very thinly a few years ago, and Song Yi stowed it at the bottom of the closet. She didn't remember this blanket until Pei Qingmian came to her room, whimpering anxiously because of the lack of nesting materials. .

So he opened the closet, found out the scent of Song Yi's youth, and sent it to his arms.

The handsome and beautiful man O held a pile of his partner's things, and felt satisfied. He clumsily held the pile and hurriedly ran to the bed.

Almost staggered by the carpet, Song Yi whispered to him from behind, telling him to slow down, don't worry.

Pei Qingmian responded, walking as fast as a fried quail caught by a cat.

Wait until you sit back on the bed. Pei Qingmian, a novice in nest building, fell into a new wave of confusion and anxiety.

After the last wave of love, his anxiety was that he had no materials for nesting, and he was only briefly happy until Song Yi satisfied him.

And now, the problem that troubled him appeared again:

How to build a nest?

Nesting is the instinct of Alpha and Omega. After differentiation, it is engraved into the genes. Few people do not build nests.

Song Yi knew that Pei Qingmian didn't know how to do it, but he was a novice and was not sure that he could make a very comfortable and perfect nest.

She understood his anxiety, so she told him softly that she was going out to fetch food and water, as well as the intimate clothing belonging to Pei Qingmian and other nesting materials sent by her family.

- She also has to build a nest, instinct is already struggling and roaring in her body, but she can give her love a time to ease the anxiety.

I hope that when she comes back, Pei Qingmian has already started "construction".

However, when Song Yi came back, she walked into the house holding her nesting materials, and Pei Qingmian stared dryly at the nesting materials in front of her.

Song Yi endured it, but in the end, she couldn't hold back, and she smiled and rolled her eyes.

Pei Qingmian raised her face silently, saw her smiling, and took a breath: "What are you laughing at?"

After he was made to cry by her, Pei Qingmian's voice became hoarse. He took a breath as he spoke, and said in a hoarse voice, "I don't know how to build a nest..."

Song Yi was frightened by his voice, her heart was high, she immediately climbed onto the bed, hugged him hard, kissed his cheek, and licked the glands on the back of his neck.

The lingering pheromone relieved Pei Qingmian's anxiety.

He looked at Song Yi and whispered, "Can you?"

Song Yi: "Actually, I don't know much either."

"However, if you don't build it once, you never will."

"We will go through many nesting periods in the future."

After Song Yi finished speaking, he moved quickly and carefully placed the nesting basket in front of him.

She began to try to build her own "lair".

The pajamas that Pei Qingmian wore when she was a teenager - she could see by touching the yardage mark, which was very inconsistent with Pei Qingmian's current physique. He must have been a thin and beautiful boy when he was a teenager, and this pajama seemed to have been in Pei Qingmian's closet, so it was soaked in his own smell, smelling like a sweet butterscotch.

With her delicate snow-white fingertips, she rubbed the loose and wide juvenile pajamas, with an extremely fascinated and clear heartbeat on her face: "I like this."

Pei Qingmian's cheeks were flushed by her cherished actions. He took pictures of the gourd and began to lay out Song Yi's clothes one by one.

His Alpha, a blanket that he used when he was a child, became a piece that Pei Qingmian could not put down.

Soft blankets, fragrant blankets.

It feels like a small cloud.

He patted and patted again with the palm of his hand. The fluffy hand felt a little thinner, but it still felt good to the touch.

He uses this as the inner perimeter of the nest, wrapping around him, to the extent that he can touch it with his cheeks just by bending over slightly.

Then there were her intimates, which were really beautiful. He had just seen how charming they were when they were taken off her and dropped to the ground.

He silently made her clothes the inner padding of the nest.

...then the restraint ring, on the blanket of clothes, and then the little things that filled her scent.

The whole room was filled with Song Yi's belongings. When Pei Qingmian felt that his nest material was not enough, he would get up from the bed and search everywhere in an open and honest manner.

When Song Yi was building a nest, he heard Pei Qingmian walking around. He even got into her closet, took out his favorite dress, blushed and asked her if she could build a nest for him with this beautiful dress, and then awkwardly asked her if she could wear it to show him next time.

How can she answer? Of course it can only be good.

Their beds were huge, and finally, when the nest was complete, both looked incredibly fluffy, soft and comfortable.

Pei Qingmian drank the drinking water handed over by Song Yi, took a few bites of the jerky, and said vaguely, "My nest is so fragrant, soft and comfortable."

"mine too."

"..."

After a while, Song Yi stared at his pink lips and said softly, "Qing Mian."

Pei Qingmian looked at her and replied in confusion, "What's wrong?"

Then, his chin was gently pinched by her, kissed, and the whispering whisper from her throat, accompanied by a rumbling grunt, was sent into his ear.

"You are so beautiful, let's do it again."

Pei Qingmian: "..."

He was overwhelmed by her, and their lair was overwhelmed.

"Wait, our nest!"

"It's okay baby, we'll build it later."

"Normally, the nests built during the nesting period will give Alpha and Omega a rest period of one or two hours, sometimes three or four hours."

"Certainly, surveys have shown that alphas with higher gland strengths have shorter refractory periods, so nests they and their mates tend to build for only a short time before being 'destroyed' until the next wave reconstruction……"

"Fortunately, the nest is mostly composed of soft close-fitting fabrics and a small amount of daily necessities. It is not as difficult as building a house in reality."

"They will slowly master the best way to build the nest during the multiple 'destroy' and 'rebuild' of the nest."

"..."

This is the knowledge point that most students pay attention to in the physiology elective course that Fei Buyu is responsible for teaching this school year.

Especially the Betas, who are particularly curious about the "talents" displayed by the AOs in "Nesting".

After class, a Beta asked his Omega classmates: "Do you all build nests like this? It's so interesting..."

Omega crossed his arms and glanced at Beta: "I don't have a partner yet, so I don't know what the nesting period feels like." Of course, a single O who uses an inhibitor to get through the fever period has no chance to experience the building that an AO partner only has. Nest period.

However, she still referred to the simple and simple experience in her own life and told Beta: "It should be very interesting, I think the natural connection of AO is very subtle, like beasts, didn't some experts say that the differentiated AO sex is other people Species, more or less, there is a phenomenon of animalization and atavism."

The developed vomeronasal organs and the existence of glandular pheromones all have the characteristics of "attribution".

Beta: "Hey, that sounds interesting!"

Omega sighed old-fashioned: "I still envy you Beta, you don't have to carry sprays with you in summer, you know, Alpha and Omega always emit smells because of body fluids in summer... That taste is really... "..." She grinned, looking like she couldn't remember.

Beta thoughtfully: "Yeah, if I were AO, maybe it wouldn't be that interesting."

...

Song Yi's susceptible period lasted for a few days.

In the past few days, she and Pei Qingmian hardly go out except for necessary food, drinking water, and changing sheets.

The whole villa was quiet. The Song family was surprised and worried from the beginning, but later became accustomed to it and didn't feel that anything was wrong.

After all, for these Betas, they can't smell the pheromone of AO, whether it is a susceptible period or a fever period, it has no effect on them.

In addition to providing the children with food and drinking water as usual, life went on as usual.

The Pei family came here on the second and third day. Seeing the calmness of the Song family, their envy overflowed a bit.

Pei Qinglang said to his father, "Dad, I envy Brother Song Shen's calmness and don't care what sister-in-law and brother are doing upstairs."

Pei Heng pinched the bridge of his nose: "I'm also envious, Beta is still good, look at your in-laws, everyone is talented, and their talents are not worse than ordinary AOs, and they are not affected by glands, so they can be used during normal vacations to travel..."

The law stipulates that in order to ensure equality in the workplace, the three genders of ABO have the same statutory holidays, but the period of leave for the two genders of AO is included in this statutory holiday.

And Beta obviously doesn't have this problem, they can travel freely on statutory holidays without being affected by the gland cycle.

Pei Qinglang held his face and complained: "I also want to be a Beta!"

At the same time, Pei Qingmian raised his hand tremblingly in the room, covered his red eyelids, and whimpered softly:

"If only I were a beta."

Song Yi rubbed his face with his fingers and coaxed him: "Why do you say that?"

Her susceptibility period is almost over, and her whole body is refreshing and happy, exuding a pleasant atmosphere from the inside out.

She could still get up energetically to get water and food for Pei Qingmian, but Pei Qingmian struggled to even lift her fingers.

The Alpha of the gland strength 3S is too powerful.

Pei Qingmian struggled and said, "Don't you think you're going too far?"

Song Yi kissed his cheek tenderly, her pupils were round and bright, and her smile was full of a little bit, as if a husband and wife were talking about the most ordinary thing: "If you are Beta, I will not let you go."

Pei Qingmian's eyes widened, trembling twice, he wiped his eyelids so hard that he almost burst into tears.
