Sister's Observation Diary (Chinese) (Family Incest Adult Novel)

Chapter 4

A few days after Hua Ling directly forced Xiuzhi to have physical relations with her. There is still no change in the lives of the two. No, it should be said that it was Hideji who insisted on maintaining a normal relationship.

During the day, the two were still a pair of siblings with a good relationship, but at night, Hua Ling began to indulge in masturbation again, while Xiuzhi hid in the closet and watched his sister's foolish behavior.

In this way, on the surface, the two of them lived a peaceful life, and Xiuzhi also thought that Hualing would gradually appreciate his persistence.

Indeed, after being flatly rejected by Xiuzhi, Hua Ling never forced Xiuzhi again.

If it were in the past, even if he was not willing, Xiuzhi would basically agree to Hua Ling's request reluctantly, but this was the only matter that Xiuzhi seemed to never compromise on. No matter how much I begged, my brother wouldn't agree. Perhaps it was because of this realization that Hua Ling did not embarrass Xiuzhi again.

However, she never changed her mind.

(I want to have sex with my brother. No matter what, I must give myself to my brother. I really want to have sex with my brother!)

Hua Ling's low sexual morals did not change even after she read pornographic books and watched adult videos.

If you have sex with your brother, it is incest. Although her brother said that this was an absolutely prohibited behavior, why? Hua Ling was still circling around this question.

What's more, only imperfect love can be passionate. Because of Yuba's existence, Karin's possessiveness towards Shuji changed from "wanting to monopolize his brother" to "wanting to monopolize Shuji as a person".

Even if she is not aware of it, when affection turns into love, the feminine part of Hua Ling will be highlighted.

(I will never lose to my elder sister. My elder brother is mine alone. So, I want to have sex with my elder brother. Just like what my elder brother did to my elder sister back then... Brother... I want to be fucked by you like Yuba-nee-san...)

For Hua Ling, she has not yet reached the stage where she wants to become her brother's lover. I just want to have physical contact with my brother.

(What should I do so that my brother will agree to my request? Should I let him know that I have a lot of knowledge about sex? Maybe he will have sex with me because of this. But...if I really tell him, it will be...very embarrassing. Besides, my brother has had sex with my sister before. I have no such experience. Will he hate me for this? But my first time was supposed to be for my brother...what should I do?)

Hua Ling's mind was full of random thoughts.

(If I have rich sexual skills, what would my brother think? If I use my hands or mouth to pump and lick his sexual organs, and make him feel comfortable, would he agree to have sex with me?)

Hua Ling was immersed in imagining herself serving Xiuzhi. However, as Hua Ling has no sexual experience, she still seems to be unsure about whether she should ask Hideji that she is willing to serve him unilaterally.

(Hmm~ Hmm. Should I have some experience in this area first? But there is no place to practice sex. And I don’t want to do this with someone I don’t know…)

Hua Ling's depressed mood and worries made it difficult for her to find the answer. Every day I keep thinking in my mind what I should do and what I should do. One day, when she saw Shuji chatting with Yuba, an idea suddenly flashed through her mind.

(If I could make love as well as my sister, maybe my brother would agree to it...)

The body that had been caressed by Yuba once again awakened the pleasure that she had felt in the health room that day.

Skilled movements and deft finger stroking techniques...If I could have the same sex skills as Yuba, I would have the confidence to seduce my brother. After discovering this truth, Hua Ling made this decision in her heart.

(Just like my elder sister. No, I must surpass my elder sister. If I do this, my elder brother will definitely agree to my request one day. I must give my virginity to my elder brother.)

After making up her mind, Hua Ling spent more time every night developing and exploring her body.

Although the brother and sister had completely different ideas, they apparently spent a peaceful month together.

Maya called out to Shuji who was waiting inside the academy for Karin to finish class.

"Mikoto-san, if you have time, could you please come over here for a moment? I want to ask you something about Karin."

Since it was related to his sister, Xiuzhi had no reason to refuse. Shuji nodded and followed Maya into the health room.

"Doctor, what happened to Hua Ling?"

As soon as he entered the health room, Xiuzhi asked about Hua Ling. Maya had a strange expression on her face when she saw this.

"Hey, Miko-sama. What's wrong with your sister recently?"

"Eh?"

"Is spring coming?"

"What do you mean by spring? Spring has already passed."

"Don't play dumb. I'm not talking about the seasons. I'm asking you if Hua Ling has a boyfriend."

"Eh...are you talking about Hua Ling?"

"That's right!"

"Why do you think so?"

"Hmm! Well, this is a woman's sixth sense. When I saw Hua Ling a few days ago, I felt that she seemed to be a different person. It was as if her behavior had become very feminine... So I wondered if she had a boyfriend. Besides, it is possible for her to have a boyfriend at her age, isn't it?"

"That's true... But why are you asking me this?"

"I was wondering, if your lovely sister really had a boyfriend, how would you react?"

"... Doctor, you are such a bad person."

"Hehe. If you want to blame someone, blame it on my life being so boring lately. What's the truth?"

"The truth? Hua Ling never told me that she has a boyfriend."

"Yeah, not really. Then why did she change so much? It's like she suddenly turned into a mature woman... If it's not love, then what could it be?"

Seeing Maya with a puzzled look on her face, Hideji suddenly became a little too proud of himself.

"I think it's because she's already awakened to sex."

"Eh."

"Girls her age are probably at the stage where they want to look sexier and more feminine."

Maya couldn't help but laugh when she saw how proud Shuji looked.

"I see. If that's the case, then I'll have to lend her a hand."

"Hey, give her a hand..."

"Encouraging students to be sexually aware is also one of the jobs of a health care doctor."

(I don’t think so.)

Maya winked at Shuji playfully and walked towards the storage cabinet next to the health room. She opened the door of the cabinet and bent down as if looking for something. Soon, she stood up, holding several shopping bags in both hands, and walked in front of Xiuzhi.

"Pick the ones you like and give them to your sister."

After saying that, Maya took out from the shopping cart a maid uniform with a special headband and a chain collar, a nurse uniform with a thermometer and a nurse cap, and a shrine maiden costume with a sky coin and a fortune stick. In addition, there are other costumes for cosplay shows.

"Doctor...what on earth are these..."

"Hehehe~. This is my personal quirk."

"Do you like costume shows?"

"Not me. It's for someone else to wear."

"…For your students?"

"As long as she's a cute girl, it doesn't matter if she's a student or a coworker. Hua Ling will look super cute in it."

"Hmm... I think she's cute no matter what she wears."

"You two seem to be quite in love. So, which one do you want? If you like them, you can take them all. But you have to show me how cute Hua Ling looks in costume."

Maya seemed to have determined that Hideji would definitely take it back, and placed the clothes one by one on the table.

(If I don’t accept Maya’s kindness, she will definitely not let it go. If that’s the case…)

After some thought, Shuji chose three outfits: a maid outfit, a leather outfit, and a gorgeous outfit.

"I think this is a maid uniform, but what is this?"

"This is the queen's outfit. This outfit also comes with a whip and candle accessories. As for the soft and gentle costume, it is the outfit of the messenger of justice."

"The messenger of justice?"

"It's the sweet red lips of the sweet female knight. Don't you know?"

“Is there anything like this on TV?”

"It seems... you will need this thing."

Maya nodded and took out a videotape from the shopping bag. The cover features a beautiful girl wearing a super short skirt and a set of gorgeous flowing clothes. However, on the back is a photo of an aggressive couple having sex. This looks like an adult video.

"You should also work hard on this videotape."

"Oh... I see. Well, doctor, thank you so much for giving me so many things."

"Wait, wait a minute. When did I say I wanted to give it to you?"

"Huh? Are you saying you want to charge me?"

The material of every piece of clothing on the table doesn't look cheap. Xiuzhi thought that if that was the case, he was about to put the clothes in his hand back on the table. However, Maya pointed her finger, signaling him to put the clothes back.

"I'm not asking you for money. My financial situation isn't such that I have to blackmail students."

"So? Doctor?"

"What do you want?"

Maya smiled with her lips pursed, quietly ran to Shuji's side, and suddenly pressed his whole chest against him.

“Ah wow wow.”

Xiuzhi suddenly lost his balance and fell backwards, but because there was a bed behind him, Xiuzhi did not fall to the ground, but lay flat on the bed. Seeing this, Maya took advantage of the situation and sat on Hideji's lower body while he was lying on the bed in a riding position, and quickly unbuttoned Hideji's uniform.

"Doctor..."

"Just be quiet and don't move."

(But…….)

It suddenly occurred to Xiuzhi that if he didn't struggle, he might be raped. Shuji was only half right. When Maya pulled open Shuji's shirt, the corners of her mouth raised slightly and she moved her palm to Shuji's tight abdominal muscles.

"You don't seem to work out normally, but I didn't expect your muscles to be so developed."

(Illustration 03)

While stroking Hideji's breasts with her palms, Maya deliberately stuck out her tongue to tease and suck on Hideji's breasts.

"Hmm~, are you planning to rape your students?"

"That's not rape at all. It's just adultery at best."

While licking Hideji's nipples, Maya pulled down the zipper of his pants, grabbed his penis directly from his underwear, and gently caressed it with her fingertips. Such stimulation caused Hideji's penis to quickly become engorged and erect.

"Mmm, what a nice touch. Bigger than I imagined."

"Imagine... Doctor, you can actually imagine such a thing?"

"What's the big deal~?"

Maya answered playfully, took her hand off the penis, and quickly pulled off Hideji's underwear. The blood-thirsty cock, once freed from the pressing underwear, stood straight up in front of Maya's eyes. Maya looked at the erect penis in fascination.

"Ahh, young people are really different."

"You don't have to describe yourself as an old man..."

"But at least you are younger than me, right?"

Maya bent her fingers, tightly grasped the hard cock, and began to move it up and down. The fingers went from the glans to the very bottom of the penis... The fingers moved in a slow and fast rhythm, which was a great achievement for Hideji, who had been living an almost abstinent life these days because he didn't want to use Hualing as a tool to satisfy his sexual desires. It's simply heaven.

“Uh-huh…. Guuuu…”

"It's okay to scream out loud. Don't you feel comfortable?"

“Hmm, hm.”

Maya leaned close to the ear of Shuji who was moaning involuntarily and said this to her. When the up and down movement becomes more intense. Hideji's lower body seemed to be hung up, ready to move.

“H-Hah, Doctor. I-I’m about to…”

Hideji himself was well aware of the fact that a large amount of semen had accumulated in his scrotum. At this moment, he was completely unable to withstand Maya's thrusting... Just as Hideji thought this, a strong feeling of ejaculation surged through his lower body. His lower body trembled violently, and Hideji shot his semen directly onto Maya's hand.

"Hehehe, why is it so fast? Is it really that comfortable?"

"Haa, huhu... what do you mean by quick... are you saying that I ejaculated prematurely?"

"I didn't say that just now. On the contrary... you seem to have been holding it in for a long time. This is not good. It's not good for your health if you keep holding it in."

Maya tried to move her fingers to determine the concentration of semen, and after stating her point in the tone of a student, she tightened her grip on Hideji's cock again. However, at this moment, the sound of footsteps was heard outside the corridor.

"Ah, listen to those footsteps..."

Maya heard the familiar footsteps, looked out the window of the health room, and a smile appeared on her face. She climbed down from Hideji's body, wiped the semen with a handkerchief, and said to Hideji.

"What a shame. Let's stop here for today."

"Eh?"

"Your sister is here."

As soon as he finished speaking, Xiuzhi jumped up hurriedly and adjusted his clothes. Just as he buttoned the last button of his shirt, the door was pushed open forcefully and Hua Ling rushed in from outside.

"Doctor Maya, I'm injured again. Please bandage me quickly~"

Maya, who had kept a certain distance from Shuji, walked towards Hualing with a tone that did not know whether to laugh or cry.

"Okay. I get it. Don't be nervous."

However, Hua Ling looked at Shuji standing behind Maya with surprise.

"Ah, eh? Brother?"

(Is my brother injured? Or is he sick?)

When the sharp-eyed Hua Ling saw that Shuji's uniform was in disarray, she suddenly remembered the scene of her brother having sex with Yuba.

(Could it be, could it be... that my brother just had sex in the health room...? And it was with Dr. Maya?)

As doubts arise, they become more suspicious. In fact, Hua Ling’s sixth sense was absolutely correct.

"Ah, Hua, Hua Ling, it's you."

Xiuzhi greeted Hualing hesitantly. But Hua Ling even forgot about her injury and just stared at Xiuzhi.

"What are you doing in the health room?"

"Eh? I, I am, because. Oh, by the way, I was talking to the doctor about you. The doctor said that Hua Ling has been coming to the health room less often recently, so..."

"...Really? Is it just a simple chat?"

"Um."

"Then why are your clothes so messed up?"

"Eh?"

"I didn't even fold my clothes."

Hearing Hua Ling's question, Xiuzhi was frightened and at a loss. Maya, on the other hand, retorted with ease.

"That's because~, this is the health room."

"?"

"Besides chatting, I also did a health check on your brother. For example, his length, hardness, etc."

"A physical examination of length and hardness?"

"That's right. The human body has many special parts. The hardness should be evenly distributed."

"Doctor~."

He originally wanted to scare Hua Ling, but when he heard Mayahui's suggestive words, Xiuzhi couldn't help but interrupt her. However, Maya remained unmoved, and as if deliberately trying to provoke Karin, she walked over to Shuji and placed her hand on his shoulder.

“Hmm~Hmm.”

This action made Hua Ling's cheeks instantly flush and puff up with anger. Seeing Hua Ling's straightforward reaction, Maya couldn't help but chuckle to herself.

"So cute, so cute. I didn't expect you really hated your brother being taken away by another woman."

"Doctor, please stop talking nonsense. Hualing, have you bandaged your wound?"

Hideji twisted his body, trying to avoid Maya's fingers moving on his chest. Xiuzhi tried to divert Hualing's attention. Normally, if Hua Ling heard her brother say this, she would immediately turn her attention to her wound. However, today, Hideji's trick had no effect. Hua Ling, who didn't want to be bandaged by Dr. Maya who had touched Shuji, suddenly turned around and ran out of the health room.

"Ah, hey, Hua Ling!"

"Ah, I think I joked too much."

"doctor……."

"Aren't you going to catch up with him, brother? But remember to take back the things I gave you, right?"

“…………”

Seeing that Maya didn't seem to care, Hideji knew that it would be useless even if he protested to her. So he hurriedly stuffed the three sets of clothes he had just chosen into his schoolbag and rushed out of the health room. However, Hua Ling's pace was surprisingly fast that day. In the end, Xiuzhi still failed to catch up with Hualing, and the two returned home one after the other.

That night, Xiuzhi had no choice but to order takeout. Because as soon as Hua Ling returned home, she locked herself in her room, not to mention cooking dinner. Because Xiuzhi didn't even have the chance to explain to her. Xiuzhi looked through the hole in the closet and saw Hua Ling, who was in a bad mood and lying on the bed angrily. Xiuzhi climbed out of the closet with a wry smile on his face.

(Hua Ling is such a stubborn girl. What can I do to make peace with her? The doctor said those things on purpose and touched me on purpose. I could have gotten along with her by just finding an excuse. But then again, compared to her catching Maya and I doing that, this is a blessing in disguise.)

However, while Xiuzhi was thinking about these things, a fire of jealousy ignited in Hualing's heart.

(It turns out that it’s not just Yuba-nee. Even Dr. Maya likes my brother. The two of them acted so affectionate, Maya even caressed my brother in front of me. They must have had sex. No, no, no, no. I don’t want to give my brother to anyone!)

Her arbitrary thinking made her ideas more and more extreme. "The forbidden love between the beautiful female health doctor and the male student after class"... Such a title flashed through Hua Ling's mind. This may be due to the influence of pornographic books and adult videos in recent times.

"No. I don't want this!"

When Hua Ling thought of the scene of Maya and Hideji having physical relations, she couldn't help but want to deny it.

My brother is mine alone...The strong desire for exclusivity dominates Hualing's rationality. Hua Ling quickly got up from the bed and rushed to Xiuzhi's room. Hua Ling opened Xiuzhi's door without even knocking.

As soon as she saw Xiuzhi, Hua Ling entered his room with a look of determination to die on her face.

"elder brother."

"Hualing. You came just in time. Let me tell you about what happened today in the infirmary with Maya."

Xiuzhi originally thought that this was a good opportunity to explain everything to Hualing. However, just as Xiuzhi was about to explain further, Hualing threw herself at Xiuzhi. The momentum was completely different from what you normally experience when playing wrestling games. Hua Ling hugged Xiuzhi tightly, put aside all her worries and spoke.

"Hold me tight. Please, hold me tight, brother."

"Hua, Hua Ling..."

Faced with this sudden request, Xiuzhi was confused. Xiuzhi felt that Hualing's behavior tonight was different from the previous lustful atmosphere where she just wanted to satisfy her sexual desires.

"Didn't I tell you before? Brothers and sisters shouldn't do this kind of thing."

"Why? It's okay as long as we don't have kids, right? As long as we can do a good job of contraception. I'll give my first time to you no matter what. So, brother, I beg you, come with me tonight..."

Hua Ling stared at Xiuzhi with her watery eyes, and big tears welled up in her eye sockets. Tears flowed to the corners of her eyes, and Hua Ling continued speaking with two lines of tears on her cheeks.

"Why can others do it but I can't? Why can Yuba and Dr. Maya do it? This is too unfair... No... I don't want it."

As Hua Ling shook her head, tears flowed down her cheeks.

(Why did Hua Ling know that I had a relationship with Yuba? What's worse, she misunderstood the relationship between me and Dr. Maya. Strictly speaking, I should be the victim...)

After hearing Hua Ling's words, these questions flashed through Xiuzhi's mind, but it was impossible for him to ask Hua Ling in person. Xiuzhi had no choice but to remain silent, while Hualing bit her lips lightly, buried her head in Xiuzhi's arms and began to sob.

“Hmm, hmm… Why did you exclude me, brother? Please, treat me the same way you treat Yuzuba and Maya. Please, brother…”

"Hua Ling..."

(Excluded... Actually, it is not a question of who to exclude...)

Although Xiuzhi wanted to explain to Hualing that this was an issue of ethics and morality, given her current situation, she would definitely not listen to my explanation. What's more, seeing Hua Ling's sad look made Xiuzhi feel even more heartbroken. The reason why Hua Ling had such an idea might be because the incident in the health room dealt a great blow to her. For various reasons, it was difficult for Xiuzhi to shake off Hua Ling's hands.

(What should I do?)

Xiuzhi's thoughts at this moment have not changed at all from when he rejected Hua Ling before. Logically speaking, he should have rejected her request outright like he did last time. However, Shuji sighed.

(It is indeed hard to feel excluded. Her jealousy towards Yuba and Dr. Maya makes me feel bad for her. Well... the two of them are not related by blood... If this is really her wish, there is no need for me to insist. If I do this with the mentality of guiding my sister...)

Xiuzhi, who unconsciously found reasons to justify his behavior, gently held Hualing in his arms.
