My senior sister is not a human being!

"Yeah." Sylvia nodded. Just as she was about to take action, she paused as if she had thought of something. Then she said to Su Yuchen, "Chen, do you remember my experiment?"

Su Yuchen was startled, then he looked at her belly as if he remembered something, and saw that on her originally fair and flawless belly skin, a cherry-red light was surging, gradually outlining a complex-looking pattern.

Su Yuchen's eyes twitched. The lines were indeed complicated, but they didn't look serious no matter how he looked at them.

"It worked!" Sylvia looked him straight in the eye. "Not only mine, I'm ready for theirs, too."

???

Su Yuchen stared at Sylvia blankly. Just as he was about to speak, he heard Sylvia continue, "Chen, guess what my name is?"

She stretched out her hand and placed it on her lower abdomen. Without waiting for Su Yuchen to respond, she continued to speak to herself -

"enthusiasm."

"That is... the enthusiasm for this kind of thing and the willingness to play with Chen in various ways."

Su Yuchen stared at the succubus in a daze, feeling that some serious knowledge had been contaminated again.

Chapter 541: The Name of the Confidential Society

At night, the lights outside could not illuminate the office of the Discipline Committee Chairman with the curtains tightly drawn, so Su Yuchen could clearly see the beautiful light patterns.

As if to make Su Yuchen understand better, Sylvia raised her finger and tapped lightly in front of him.

Her unique pink magic power turned into silk threads, gradually outlining a beautiful light pattern in the air.

As the magic power was outlined, it gradually condensed into a small pink heart, and there was a circle of slightly larger hearts on the outside. On both sides, the devil's wings spread out, ready to fly.

Looking at the patterns taking shape before his eyes, Su Yuchen had only one feeling: excitement.

Should I say she is worthy of being a succubus?

"Well... I feel Chen's happiness."

Sylvia's breath became hotter. She still leaned back and gently stroked the back of Su Yuchen's neck with her fingers: "Do you want to touch it?"

Su Yuchen followed his instructions and stretched out his hand and placed it on the light pattern in the air. The touch was not special, but just warm and comfortable like warm water.

Su Yuchen licked his lips and stroked the beautiful lines while curiously asking, "Passion?"

"Not only can I play with you like this, I can also play with you like that," Sylvia explained.

"What a positive word..." Su Yuchen looked at her with amusement and helplessness, and then asked: "What effect does it have?"

"Is it like the traditional contract magic, where a single thought can have the effect of stimulating desire?"

"Did Chen hope to have this effect?"

"I hope not." Su Yuchen shook his head without hesitation.

“I guessed right.” Sylvia held his cheek and handed it over: “Drink.”

A fragrance lingered at the tip of his nose. Although Su Yuchen was more curious about this pattern at this moment, it was obviously not something that could be wasted.

Sylvia lowered her head and gently stroked the back of Su Yuchen's head, and continued: "The relationship between Chen and us is that of a junior and senior student, so there is no need to control him in this way."

"Besides Maomao and me, Yu Shuang and the others would also cooperate with Chen even if they didn't rely on this."

"But if the pattern is given the effect of activating desire, then they will completely become balls of lint that only know how to roar and scream. Chen will definitely find this meaningless."

"Intimate contact is always secondary to the enjoyment of this affection, so it is impossible to reverse the order and lose most of the pleasure."

"So I am not applying any effects now. This is just a proof of the effect... the proof is that it is the effect of the dust's fluff... all things."

Su Yuchen, with his Adam's apple rolling a few times, looked up at Sylvia's cherry-pink eyes and said with emotion: "I would like to call you Academician of the Succubus."

Sylvia looked straight at Su Yuchen: "I like this title."

Su Yuchen pinched her cheek: "Great."

Unconsciously, Xiyu's spirit had been sublimated once again.

She was right. Although this kind of contract magic developed based on contract magic had miraculous effects at certain times, Su Yuchen did not want it to work on them.

There are many pleasures in life. If they all become like hungry succubi, it may be a little novel at first, but they will definitely become boring afterwards. After all, their charm will definitely be reduced when their minds are dominated by desires.

What's more... I definitely can't handle it if I keep fighting seven people alone.

"But..." Sylvia's tone suddenly changed, and she continued calmly: "I hope to add a little fun."

Su Yuchen couldn't help but smile: "Let me listen."

"If it can't be lit up with the help of dust within a certain period of time, it will generate electricity... What do you think?"

When Sylvia made her suggestion, her eyes were bright: "If they can't light up, they will definitely be anxious and feel that they haven't made Chen happy, so they will work harder. At the same time, they will unconsciously compare themselves with others. If they can't light up, and they can, there will definitely be a psychological gap... This psychological gap is a punishment."

"How does Chen feel?"

"Electric current..." Su Yuchen's eyes jumped: "Isn't it a bit too much?"

"It's an electric current that won't hurt your body." Sylvia said seriously.

"Forget it." Su Yuchen hesitated for a few seconds and shook his head: "Even if we don't rely on this, we can slowly experiment with various plays, so just like your initial idea, just let this be a symbol."

"Okay." Sylvia was not too disappointed. After all, the appearance of this pattern alone was enough to make Chen impulsive.

"You just said that you prepared something for them, too. Let me hear how you prepared it." Su Yuchen looked at her beautiful light pattern and couldn't control himself. While asking...

"I am passionate." Sylvia said with a tremor in her voice: "Yu Shuang is selfless."

"What do you mean?"

"It means 'take them all down,'" Sylvia explained. "It fits the bill, doesn't it?"

Su Yuchen opened his mouth, but really had no way to refute.

"Cats are devoted. 'Raorao can give everything to her master meow~'."

"Christia means self-reliance." Sylvia gushed, "It means 'You lie down, and this queen can do it herself'."

"My sister... I haven't made up my mind yet, because I don't know how she will behave."

"No, how did you associate these positive energy words with these?" Su Yuchen looked at Sylvia blankly: "I can't look directly at the original meaning anymore."

"It's similar to the contrast of 'Let the Nun Fall'." Sylvia, who was about to get full, pushed the hair stuck to her cheeks behind her ears: "It sounds more bitter, right?"

Su Yuchen took a deep breath and said helplessly: "It's you indeed."

Sylvia raised her chin and said, "Chen, how about setting up some fun trigger conditions?"

"What conditions?"

"The essence of this contract magic is to make the servant remain loyal to the master. If you resist being loyal to the master, you will be punished."

"We are definitely loyal to Chen, so let's modify the conditions of 'loyalty', for example, Yu Shuang..."

Sylvia paused and bit Su Yuchen's shoulder for a while before continuing, "The selfless Yu Shuang will definitely not always be selfless. When the contract magic is triggered and the contract effect is activated, it means that she is jealous."

"Chen knows that he should coax her, right?"

"Depending on the degree of lighting, it would be interesting to use different levels of coaxing to make the effect disappear, right?"

"You're so smart." Su Yuchen laughed, "It's not impossible to do this... But the effect of this contract magic is limited to the body and not limited to the mind."

"Yeah." Sylvia nodded: "It's limited to the body. Otherwise, the mental 'thinking' will have a greater impact on the body."

"According to what you said, how can we trigger the 'dedication' of Raorao and the 'self-improvement' of the Queen?" Su Yuchen smiled: "The possibility of Raorao 'not dedicating' is too low."

"But cats are easily shy." Sylvia said calmly: "They want to contribute, but they can't let go because they are shy, so Chen knew that he should find a way to make cats relax."

Su Yuchen was somewhat amused and confused: "Even if it's not like this, I know how to let her relax."

"I know, it's essentially just an auxiliary means." Sylvia walked towards the full body: "So you don't need to care about the details. What's important is the temptation presented by this tattoo."

"Depending on the degree of their inner 'wants', the effect of the contract magic can be removed by touching or going further..." Sylvia paused and continued: "Chen is saving them from the whirlpool of desire. He is a hero!"

Su Yuchen gently stroked her back, took a deep breath and said, "Well... just don't go too far with this kind of thing, and you can handle the rest."

Apart from being interested in the light pattern, he was not very interested in other additional effects.

Anyway, it’s just a little auxiliary fun thing, so let’s talk about it after Sylvia and Sister Yu Shuang discuss it.

Sylvia was sensible and did not continue the topic. She could sense that Chen's interest was limited, so she decided to discuss it with Yu Shuang and the others later to see if they had any better ideas.

So she began to concentrate on eating until she was 90% full, and as for the remaining 10% full... she wanted to play with the cat.

"Come to my house tonight?" Su Yuchen asked softly.

"Yeah." Sylvia hugged the back of Su Yuchen's head: "I want to play with the cat."

Su Yuchen glanced at the heart-shaped tip of her tail: "So you want to control it now?"

"Yes." Sylvia said seriously, "Because my period will come the day after tomorrow, Chen must feed me before then."

"With your personality, you won't be able to stay quiet even if you come." Su Yuchen teased.

"Indeed, I won't, but I can't get full in other ways." Sylvia looked down at Su Yuchen: "Does Chen want to take a bath..."

Snapped!

Su Yuchen gave her a slap on the head: "During this special period, take good care of your body and stop thinking about dirty things every day."

"Dust can't stop my desire for sex." Sylvia said lightly: "I'm 90% full."

Su Yuchen breathed a sigh of relief. Just as he was about to pick up his phone to check the time, he saw Sylvia standing up and asked, "What's going on?"

"Operation CD."

Su Yuchen looked at her with amusement, she really knows how to talk.

"Half past eight..." Su Yuchen relaxed his body: "I can go home now."

"Are you going to pick up Christia?" Sylvia looked up at him.

"Ah."

"Maomao and I are waiting for the dust at the bottom of the building." Sylvia said, "There is one more thing."

"what's up?"

"I want to start our club tomorrow." Sylvia licked her lips and said, "You can talk to Christia and ask her to be the advisory teacher."

"Okay." Su Yuchen nodded.

The clubs at Sky University are dominated by students from the Amaterasu Kingdom, so it is in line with their country's characteristics that a certain number of members and advisory teachers are required to be approved for application.

However, Su Yuchen was not worried about this. With Yae Mio around, it would be easy to set up a club.

"Have you thought of a name for the club?" Su Yuchen asked.

"I've thought about it, but I won't tell Chen now."

"You can't tell me that?" Su Yuchen laughed, "You didn't come up with a weird and eye-catching name for the club, did you?"

Sylvia stared at Su Yuchen for a while, then silently looked away.

Looking at the cute appearance of the little succubus, Su Yuchen couldn't help but stretched out his hand and pinched her cheek: "It seems that what I said was right."

"Come on, tell me what the name is. Otherwise, when you apply tomorrow, it won't pass the review."

"It will definitely pass the review. Although it will arouse other people's curiosity, outsiders will never understand the deep meaning of the name!" Sylvia said seriously.

Seeing that she refused to tell him her name, Su Yuchen naturally became more and more curious, and directly threatened her: "If you don't tell me, I won't let you play with Raorao!"

"If you don't want to play, then don't play. I'm 90% full now, so I'm not afraid."

"..."

"Have you forgotten who fed you?"

Sylvia blinked, got up and started to pick up the clothes scattered on the floor: “Go home.”

She was so full that she looked like a dead pig that was not afraid of boiling water.

Su Yuchen helplessly slapped her plump thighs and had to suppress his curiosity, comforting himself that he would know tomorrow anyway.

I changed my clothes, cleaned the sofa, and walked out of the office.

"Hey, Sister Aofei, you're still here?!" Roxanne Catherine, vice chairperson of the Discipline Committee, was surprised at first, but when she saw Sister Aofei holding Su Yuchen's arm, the expression on her face suddenly became ambiguous.

She heard from others that Sister Aofei had brought Su Yuchen back, and she had planned to meet them. However, when she arrived at the office door, she found that the lights inside were dim, and she thought they had left to get a room.

I didn't expect to meet you here unexpectedly when I was about to go back to the dormitory after get off work.
