"This ......" Su Mu couldn't help frowning slightly after hearing Su Xiaoli's words, and didn't speak.

"Brother?" Su Xiaoli saw that he didn't speak, so he called him again.

……

Su Mu thought for a moment, if he didn't answer Su Xiaoli's question, she wouldn't be able to ask Lin Jiu again, if she asked Lin Jiu, it would be better, I was afraid that she would discuss these issues with the other male classmates in the class.

Thinking of this, Su Mu narrowed his eyes slightly, and said lightly towards Su Xiaoli's voice: "No, my brother promises not to be angry." ”

"Really?" Su Xiaoli's eyes lit up suddenly, and he asked Su Mu, "Brother, how was the child born?" ”

“……”

When Su Mu heard Su Xiaoli's question, his eyes couldn't help but glance towards Lin Jiu next to him.

I saw Lin Jiuzheng pricking up his ears, waiting for him to come back with a concentrated look.

Su Mu pondered for a moment, and then replied lightly: "Children are all born by their mothers." ”

"Then why do mothers give birth?" Su Xiaoli looked at Su Mu very seriously and asked: "We mentioned in our physiology knowledge class that children develop from fertilized eggs, mothers provide eggs, and fathers provide sperm seeds, but the problem is that there is no book on how fertilized eggs are formed." ”

Su Xiaoli looked at his brother with a puzzled expression and said, "How did the fertilized egg get into my mother's belly?" ”

“……”

Su Mu listened to Su Xiaoli's question, and only felt that he wanted to die.

"I used to think that as long as boys and girls sleep together, girls will get pregnant and have babies, but I often sleep with my brother, why don't I have babies?" Su Xiaoli continued to ask towards Su Mu.

"Ahem......" Su Mu coughed lightly a little embarrassed, and suddenly felt that this kind of question might as well be answered by Lin Jiu.

"Brother?" Su Xiaoli blinked a pair of big black and white eyes, his eyes were full of curiosity, and asked him.

"This ......" Su Mu stiffened his head and replied with a stammering face towards Su Xiaoli: "Because the physiological structure of boys and girls is different, it ...... Well...... The egg is originally in the girl's body, and then the sperm seed is ...... The boy is sent into the girl's body, so they merge to form a fertilized egg, and they become a baby. ”

Such an answer should be barely acceptable, right?

Su Mu reached out and wiped the sweat from his forehead.

"Then how did the boy get the sperm seed into the girl's body?" Su Xiaoli still looked at him with a confused look and asked.

“……”

This one......

Su Mu's forehead couldn't help but sweat.

He couldn't help but raise his head and look towards Lin Jiu.

However, Lin Jiu quickly turned his head and looked out the car window, pretending that he hadn't heard anything.

"That...... It should be that the boy poked the girl's reproductive system with his own reproductive system, and then ...... Well...... That's it......" Su Mu blushed with a handsome face, and said incoherently towards Su Xiao.

？？？

Su Xiaoli thought for a while and asked him, "Is it that the boy poked the girl's little sister with his little brother?" ”

"Ahem...... Almost......" Su Mu felt that his face was so hot that he could boil eggs.

"Liar!" Su Xiaoli said with a disbelieving expression: "I have dragged my brother's little brother before, it is soft, and it can't be used to poke people at all!" ”
