[Comprehensive] BUG theory of relativity

"Nan-chan, did you quarrel with Yu-chan?" Saiki Kurumi looked worriedly at Kusuo who was sitting on the sofa jumping off the platform, "No, quarreling is not good."

'No, it doesn't. Kusuo shook his head and denied it without even thinking about it, "Why do you think we quarreled?" '

"Because Youjiang hasn't come to our house for many days."

"...Ah..." Kusuo blinked his eyes, he actually felt a little tricky about this matter.

"Did you really quarrel?!" Kurumi, who misunderstood because of that 'ah', put down the things in her hands and sat in front of Kusuo.

"I said no, Yushan is probably..." I'm shy..." Don't worry, Mom. '

"Do you need Mommy's help?"

'That would be really bad! Kusuo waved his hand and hurriedly comforted Saiki Kurumi.Originally, Yuyama was very shy because Saiki's parents knew the "fact" of what happened between the two. If Saiki Kurumi went to "help" again, Kusuo's head hurt a little, and he had already seen the bad things that would happen afterwards. the result. 'We really didn't quarrel, and we will definitely bring Youshan back for dinner tomorrow! '

Saiki Kurumi still remained skeptical, and finally went out with a frown.

"Ha..." Kusuo breathed a sigh of relief.

A week had passed since the decisive change in their relationship that afternoon.Within a week, Yushan never had the nerve to enter Saiki's house again, and his sense of shame was overwhelming.

Originally, it is reasonable for puberty teenagers to have such and such things happen, especially for couples who have already confirmed their relationship, it is even more normal.

Although it's not the one that Gong is attacking, Yushan also enjoys the previous experience... Cough, skip this one.

The issue is!On the day of their first experience, Kusuo's parents knew everything about the two of them clearly!This made You Shan, who has always been thin-skinned, unable to bear it. That morning, You Shan was able to insist on finishing breakfast at Qi Mu's house, and You Shan also admired himself.

Now when he was in school, Yuyama still went in and out with Kusuo, and even brought his own desserts and coffee puddings at lunch, and fed them to a certain coffee pudding man, but—he just didn’t enter Saiki’s house.

I always feel that I have no face to see Qi Mu's mother and Qi Mu's father again!

Similarly, Qi Mu, who had already prescribed meat, also abstained from sexual intercourse for a week after eating a delicious meal.

"Hey, our bodies are still too young now. If we indulged too much when we were young, we will experience the consequences in the future. So, be restrained!" This is what the boy Yoshida Yuyama said righteously.

"What Yushan said..." Kusuo nodded under Yushan's surprised gaze, but Kusuo didn't say the last half of the sentence. [When the accumulation reaches a certain level, you also have to take responsibility, even crying and begging for mercy. 】

Kusuo who turned on the [-]-ban switch has become completely unrecognizable!

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

"Kusuo?" Yuyama, who returned to his room after dinner, looked at Kusuo who was flipping through the comic books in his bookcase in surprise, and put down the half-drinked strawberry milk, "Why are you here?"

"Replenish your energy."

"Varied……"

Kusuo's tongue was in Yushan's mouth to attack the city, and Yushan retreated step by step under Kusuo's attack, but the enemy was too fierce, and finally defeated his reason. Physical exertion, wheezing and low 'painful' sounds from time to time.

When the two separated, a silver thread with a strong taste of work was pulled out between their lips and teeth.

The two teenagers who had sex before were a little too excited because of this too lingering kiss, and there was an aura in the air that made people blush and heartbeat.

I would be too sorry to waste such a good time.

Kusuo was well prepared, this time he used a very normal KY, which was exchanged from his room just now with the exchange ability.As for the origin, Kusuo felt that it was better not to tell Yushan about it.

The bedroom of Saiki Kusuo in the Saiki family has undergone a major renovation, the most obvious of which is that his simple single bed has been replaced by his parents with a rather comfortable double bed. The bedside table has three drawers. Except for the top floor, the remaining two floors are filled with this thing.

Parents who are very enthusiastic and think about their sons.

Standing in his room at that time, Qi Mu Guochun gave him a thumbs up, looked at him with deep eyes, smiled and teased Kusuo who had been bullying him: "You don't have to worry about it in the future, Kusuo."

However, Kusuo was not Yuyama, and he just nodded calmly at Saiki Kuniharu's actions, showing no sign of embarrassment, which made Saiki Kuniharu feel a little bit frustrated.

But this preparation in advance is still very good, much better than the previous olive oil.

After getting used to the initial pain and discomfort, Yushan Hong endured the attack from Kusuo with the corners of her eyes closed, and covered her mouth with one hand to prevent herself from making a sound.

After everything calmed down, Youshan was lying on the bed 'weak', exhausted a lot of energy, and now he couldn't open his eyes.

"おやすみ, go to sleep." Kusuo hugged him, [teleport] to his own bathroom, to do the final cleaning.

***

Once a person's bottom line is broken, it is not a problem at all to break through again.

After waking up again in the morning, Yushan changed into a comfortable position and began to reflect. Why was he directly suppressed yesterday without even fighting?Is it true that after being pressed once, you get used to it?

What a terrible habit!

If there is no pursuit in life, what is the difference with a salted fish!

Although now he is so tired that he has become a salted fish_(:з」∠)_

"Xiao Yu, get up quickly, breakfast is ready." Yoshida Saki knocked on the door.

"Understood Mom." The voice was hoarse from overuse, Yuyama rubbed his sore waist, and pushed Kusuo who was awake but not moving at all, "Hurry up and help me recover."

Who said before that you can't use superpowers like this?

Throw it away after use, maybe it's about Yushan's current situation.

Yuyama, who was alive and kicking again, changed into his uniform, waved to Kusuo, and went downstairs, leaving Kusuo who worked hard in the room.
