... "Huh? Just kidding, haha, I must have misheard." Kyoko said awkwardly. "Mi Si, I only found out you have such a loving brother when you were hospitalized. I'm so envious." Zi Xi said. "Yeah, that's right. Meng Li is my dearest person." Liu Mishi said. "Dear...??" Zi Li asked strangely. "Yes, we're close. Haha. My little sister is funny..." The brother quickly explained after hearing Mi Si's misunderstanding . "Oh, haha..." Zi Xi also laughed awkwardly. Liu Mishi talked a lot with his classmates, and the brother kept explaining, making everyone a little awkward . "Meng Li, is your sister... alright?" Nuo Xiao Zi secretly asked her brother. "She seems... a little abnormal." The brother whispered. "By the way, Kyoko. Nuo Xiao Zi said she wanted to get you pregnant, how's that going?" Liu Mishi asked innocently. "Huh?! Nuo Xiao Zi! I didn't know about this." Kyoko was a little confused by Liu Mishi's strange question . "Mi Si, did Nuo Xiao Zi really say that?" Jing Zi lowered her head and whispered. "Yes, she did. She said she wanted to fill your uterus with her semen every day before going to work," Liu Mi Shi said. "Wh-what? He would actually say something like that... I thought he was a very cheerful person..." Jing Zi said with some complicated feelings. Nuo Xiao Zi heard Liu Mi Shi's words, frowned, and said to her brother in a low voice, a little angry, "Meng Li, your sister seems to be talking bad about me." "Is that so? Haha, that's really... strange." The brother said helplessly. The banquet continued in this strange way. Apart from Liu Mi Shi saying some strange things from time to time, the atmosphere was still quite good. Halfway through the banquet, the brother went to the toilet. The brother went into a private room and thought while urinating that his sister must still be affected by the experiment and hadn't recovered yet. It seems that he has to explain some things to her properly. "Meng Li, I'm here." His sister's voice suddenly rang out. "?! Sister?! What are you doing here? This is the men's restroom!" The brother saw his sister open the stall door, hurriedly pulled up his pants, and whispered. "Yeah, what's wrong?" the sister asked curiously. "What are you doing in the men's restroom? Get out of here!" the brother said anxiously. The sister didn't leave, but instead locked the stall door from the inside. "Mengli, I'm so tired. This kind of banquet has used up too much of my magic. Please replenish my magic." Liu Mish said seriously. "Magic? You're talking nonsense." the brother said. Liu Mish lifted her skirt, and the brother was surprised to find that his sister's body was covered with red ribbons. His sister's fair body looked so alluring under the red ribbons. The sister pulled aside the red ribbons, revealing her vulva. The brother was surprised to find that his sister had actually come with vibrators. One was the largest in her anus, followed by one in her vagina. Moreover, there was even a small vibrator inserted in her urethra. The brother didn't even know how she had inserted them. The brother saw that the three vibrators were still vibrating continuously. No wonder my sister felt tired. She probably had countless orgasms already . "Mengli, help me take the dildo out of my vagina," Liu Mishi said. "This... isn't that inappropriate?" Taking out a dildo from his sister's vagina in a men's stall—what kind of thing is this ? The brother found it hard to accept. "Ugh~ I'm going to orgasm~" My sister suddenly shuddered and collapsed onto her brother. The brother quickly caught her. His sister exuded an alluring fragrance. She looked incredibly cute during her orgasm. Her soft body stimulated his senses. His penis slowly hardened . As her orgasm subsided, she hugged his neck, licked his earlobe, and said in a languid voice , "Mengli, I want it~" Her voice aroused his desire. He didn't care anymore, grabbed the dildo from her vagina, and pulled it out. "Ugh, it's so tight," he said, feeling the resistance on the dildo. "It's okay. It's okay to be a little rough," the younger sister said affectionately. With her consent, the older brother used all his strength without restraint. Every time he pulled out a little, the younger sister would let out an alluring moan. Only after it was completely pulled out did the older brother realize that the dildo had many rubber barbs. The pleasure from the barbs scraping against the vaginal wall must have been very intense. "Meri, is it out? Also, there's another ring inside, pull that out too," the younger sister said. The older brother saw a ring in his sister's vagina and pulled it out as she asked. He had only pulled a little when he encountered great resistance. He was puzzled, but didn't think much of it and continued to pull. "Ah~ so stimulating~" the younger sister continued to moan. The older brother used more and more force until finally, with a "pop," he pulled out a ball the size of a fist . This ball looked like a sea urchin, covered in rubber barbs.

"Where did this come from?!" The older brother exclaimed in surprise upon seeing such a grotesque object. He then
realized that the ring he had seen earlier was connected to this ball by a transparent thread.

"This ball is so heavy. Where was it originally? Could it be... my uterus?" the older brother asked in astonishment.

"Yes, Mengli. This is the detached ball you gave me. You've pulled it
out ," the younger sister said.

Looking at his sister, who resembled a perverted masochist, the older brother felt no aversion; instead, he found it even more stimulating, and
his large penis swelled to a purplish-red.

"Mengli, hurry up and put it in," the younger sister urged.

The younger sister left her brother's embrace, turned around, placed her hands on the door, and bent over, ready to be
violated .

The older brother didn't care about anything else and thrust his large penis hard into his sister's vagina.

"Ugh! So tight!" "Ah~"

Both of them groaned simultaneously. The older brother's penis slowly penetrated deeper into his sister's exquisite vagina. As a result,
the brother's penis only went in halfway before hitting the cervix.

"So shallow! How come it's already hitting the cervix?" the brother asked curiously.

"Because of the detachment ball. Mengli, hurry up and put it in," the sister said.

The brother noticed that the sister's cervix was wide open. That makes sense, after all, he had just pulled
out .

With a push, the brother inserted the head of his penis into the sister's uterus.

The sister adjusted her body, and surprisingly, the cervix contracted, firmly locking the brother's penis head.

"Mmm, so tight. The cervix can actually contract. That's amazing," the brother said.

"Okay, Mengli, now you can thrust as much as you want," the sister said.

The brother continued to push in, until he reached the uterine wall, and continued pushing against the uterus. "Ah~ so stimulating~ the big penis is directly rubbing against the uterine wall~" the sister would moan

when the brother thrust . The direct stimulation of the delicate uterus brought the sister intense pleasure. Moreover, directly penetrating the sister's uterus brought the brother enormous psychological pleasure. After reaching the very end, the brother slowly pulled out. To his surprise, the sister's uterus remained firmly attached to his penis, moving with it. "So good, so good~" The uterus felt as if it were about to be expelled from her body, a unique pleasure that further stimulated the sister. Then, the brother began to slowly thrust in and out. Each thrust brought immense pleasure to both of them. As their desire grew, the brother thrust faster and faster. The back-and-forth thrusting of the uterus brought the sister intense pleasure. Before long, the brother was about to ejaculate. "Ugh! Sister, I'm going to cum," the brother said. "Ah~ I'm going to orgasm~" The sister was still immersed in pleasure and didn't pay attention to her brother. "Ugh! I can't pull out..." Feeling that he was about to ejaculate, the brother tried to pull his penis out. But the sister 's uterus remained firmly attached to his penis. "Sister, let go!! I'm going to cum!" the brother said anxiously. "Huh? It's okay, just shoot inside. Otherwise, how will I recover my magic?" the younger sister said. "You'll get pregnant!" the older brother said. "...I've always wanted to have Mengli's child," the younger sister said affectionately. Then, the older brother ejaculated hot semen. The semen impacted the younger sister's uterine wall, bringing her to an immediate orgasm. "Ah~ So hot~ Mengli's hot semen shot inside. Mengli, are you happy?" the younger sister said. "...Yes. Happy," the older brother said. This abnormal younger sister made her seem even more like a nymphomaniac, yet she aroused the older brother's lust even more. The older brother ejaculated a lot of semen, and the younger sister was about to let the older brother's penis withdraw . "Mengli, give me the detachment ball. I want to put it back in. I don't want any of Mengli's semen to be lost," the younger sister said. The detachment ball was originally thicker than the vagina, so it pushed the outflowing semen back into the uterus. The older brother was surprised to see the detachment ball enter the younger sister's body and keep going upwards. Finally, it reached the cervix. "Heh~ I need a little help~" The younger sister picked up the dildo from before and inserted it into her vagina. Because the dildo was much longer than her vagina, it pushed against the detachment ball, opening the cervix and slowly moving into the uterus. "Ah~ So stimulating." The barbs on the detachment ball scraped against the uterine wall, giving the younger sister an even stronger stimulation . There was already a lot of semen in the uterus, and now the detachment ball squeezed in, making the small uterus even larger. Finally, the younger sister managed to insert the entire detachment ball. The younger sister was panting, while the older brother was a little at a loss. "Memiri, I'm leaving now." After tidying everything up, the younger sister left. It was noticeable that she walked a little strangely. But who would know the truth? The older brother remained in the private room. Seeing his younger sister like this for the first time, the older brother had very complicated feelings. "When did she... become like this?" He left the restroom and returned to the banquet. The older brother looked at his sister chatting and laughing, and couldn't connect her with the perverted woman from before. "Things are getting a little tricky..." Back home, the older brother took out his textbooks and notebook. His younger sister had been in a coma and had fallen behind in her studies. He had written a notebook specifically for her to review her lessons. Looking at the notebook , a wave of affection for his sister washed over him. "Now, let's go help her with her studies," he said, knocking on her door. "Sister, um, are you free? I brought a notebook. You've fallen behind in your studies lately, and I want to help you catch up." "Mengli? Come in," his sister's voice came. "Okay, I'll come in then." He opened the door and went inside. The moment he saw his sister, he was stunned by her appearance. She was wearing a pink dress, the kind that barely covered her bottom. Moreover, the pink dress was semi-transparent; if you looked closely, it seemed as if she were naked. "Sis, sis, why are you dressed like this?" he exclaimed, deliberately averting his gaze. "What's wrong? Am I wearing too much? I'll take it off now." With that, the younger sister started to remove the only piece of clothing she was wearing . "No, no!" the older brother quickly stopped her. But his hand was already on his sister's waist.

The dress gave her brother a silky feel. It wasn't hard to guess that it was expensive.

The younger sister didn't stop her brother's hands; instead, she started to undress him.

"Mengli, I feel like this time is a little different. I think I really might get pregnant with your child. So,
let's do it one more time," the younger sister said affectionately .

Only then did the brother realize that he had indeed ejaculated a lot of semen into his sister's belly at the banquet yesterday. If they hadn't
taken any contraceptive measures, she might really be pregnant.

"Take birth control pills, little sister. Otherwise, you really will get pregnant," the brother said.

"Okay, I know. But before that, let's do it one more time," the younger sister said.
Then , she started to undress her brother.

The brother didn't resist, and his clothes were removed by his sister. Actually, the brother also missed
his sister 's body and that exhilarating pleasure.

The younger sister pushed her brother down onto the bed and began kissing him. Although the brother was passively receiving her kisses,
he was very happy.

"Mmm," the brother said, "little sister, your lips are so sweet."

"Yes, I put on lipstick," the younger sister said playfully.

"Lipstick?" the brother asked, puzzled.

Faced with his sister's aggressive advances, the brother also enjoyed the thrill of being pushed around by a girl. Suddenly,
he realized he hadn't come to his sister for sexual pleasure, but to teach her.

"Ugh," he said, panting, "Sister, stop." "I'm here to teach you."

"Teach you? If you want to learn, push me away. I won't get up on my own,"
the sister said in a seductive voice.

The brother placed his hands on his sister's body, hesitated for a long time, but ultimately didn't push her away. He
hugged his sister, saying helplessly, "I give up."

"Hehe, although you're all serious, your body doesn't want to leave me," the sister laughed.

"But, learning is still necessary." The sister sat up, looking at her brother's already erect penis,
and said, "This time, it's even bigger."

She aimed her brother's penis at her vagina and inserted it. Both of them
groaned .

"Ha, brother, don't slip out! Just like that, hold me while I study." The younger sister turned around,
her back to her brother, and said.

"!! This! That's too much." The older brother said helplessly.

"What's wrong? When I was still King Amish, didn't you always do this? In front of the ministers,
you'd make me sit on your lap, your big cock inside me, making me lose all my royal dignity."
The younger sister laughed.

The older brother was a little confused; his younger sister was saying strange things again. Oh well, never mind. The older brother picked up his younger sister,
his big cock still pressed tightly against her vagina, and walked to the chair in front of the table and sat down.

"Ah, Mengli, you're so good." As soon as he sat down, due to his weight, he thrust in hard, even
reaching the opening of his younger sister's cervix. The loli-like younger sister in his arms, and the faint fragrance on her body, all aroused
the older brother's nerves.

"Mengli, these are your notes, right? Then let's begin." The younger sister said.

So the younger sister opened the book and began to study. At this moment, it was the older brother who couldn't take it anymore. He held
his sister's body and began thrusting.

"Ha~ Ha~" The sister's body was moving violently, but she still opened her notebook and textbook and began to study.

The older brother held his sister, pulling his penis almost completely out each time, then releasing her body and letting her
sit down hard. The intense movements brought both of them intense pleasure each time.

"How~ how~ calculated~ this formula~" The intense pleasure made it impossible for the sister to think
normally . She couldn't even solve the first problem. Her scratch paper was covered with crooked and messy writing.

"Ah~ Ah~ It's so~ so hard~" the sister groaned.

The older brother's hand also touched the sister's breasts, further stimulating her.

"Hmm~ Sister, your breasts... have gotten bigger." The older brother said subconsciously.

"Ah~ really~ ah" the sister replied.

The older brother gradually increased his speed, hoping to get even more intense pleasure.

"Ha~ Ah~ I can't~ think at all~" the sister said. The intense pleasure filled the sister's brain,
making even the simplest thinking impossible.

The brother's penis penetrated all the way in each time, rubbing against the sister's cervix. Gradually, the sister's cervix
opened, and the brother's penis went in as well.

"Mmm~ Mengli's penis is inside the uterus~" the sister said.

When the brother was about to pick up the sister again, the sister stopped him. The sister turned around and kissed the brother
's lips.

"Mmm~ Mmm!!" The sister's tongue brought not only saliva, but also something unknown. The brother
was wondering about it when the sister's tongue pushed that thing into his esophagus.

"Mmm~ Sister, wait, what did you give me?" the brother asked.

"I won't tell you." the sister said mischievously.

While kissing the brother, the sister controlled the cervix to slowly contract, firmly locking the brother's
glans .

"Okay. I have to continue learning." The sister turned away again.

So, the brother continued to thrust. This time, each thrust moved the sister's uterus. The friction of the sister's
uterus inside the vagina brought the sister even more intense pleasure.

"Ah~ Ah~ This is still the most exciting~" the sister said.

Not long after, the intense pleasure brought the younger sister to orgasm.

"Ah~ I orgasmed~" the younger sister moaned.

At this moment, the older brother was about to ejaculate as well. Hot semen slammed against the uterine wall.

"Ah~ This feeling of being ejaculated inside~ So stimulating~" the younger sister said.

The older brother ejaculated a large amount of semen, but his penis did not shrink.

"What's going on? What did you give me?" the older brother asked anxiously.

"It's a sperm enhancer. Today, I'm going to drain you dry." the younger sister said playfully.

"You!!" the older brother tried to pull his penis out, but the younger sister shouted, "It hurts! Mengli, are you trying to pull my
uterus out?"

The older brother was so scared that he quickly put his penis back in.

"Want to take it out? Then wait until your penis really softens." the younger sister said with a lewd smile.

The older brother thought, this is it.

After a long time, the older brother finally separated from his younger sister. Looking at the younger sister's obviously swollen belly, the older brother had already forgotten
She realized how many times she had ejaculated.

"My belly is full of semen, I'm so happy," the younger sister said.

"Remember to take your birth control pills," the older brother said.

"Okay. I'll go take them now." The younger sister then went to open the medicine box.

"Birth control pills~ Is this it? Wait?! Oh no, this is the real birth control pills... Kyoko, I'm so
sorry ..."

...

Kyoko looked at the two bottles of pills in her hand.

Truth serum and birth control pills. These were given to her by her best friend, Liu Mishi. She had already invited her crush, Nuo Xiaozi, to
her house. Yes, she was going to confess to her crush. If she didn't succeed, she would use the truth serum to find out who he liked and
why he didn't like her. If that still didn't work, she could seduce him with her body. To avoid pregnancy, Liu
Mishi had also given her birth control pills. At this moment, the doorbell rang. It was obviously her crush, Nuo Xiaozi.

"I must succeed!" Kyoko said confidently.

...

The truth is, there is no such thing as truth serum in this world. What Liu Mishi gave Kyoko was a strong aphrodisiac. If Nuo
Xiaozi refuses, drug her. Then, Jingzi can also get her hands on her crush. It's despicable, but
it doesn't matter.
