My senior sister is not a human being!

Watching Sylvia deftly take out the exquisitely packaged snacks from the magic storage props, Su Yuchen understood that she really came here with the intention of "being here", and she was very considerate to prepare "tea" for her and snacks to restore her strength in advance.

Really so gentle.

"Senior Sylvia."

"Ok?"

Su Yuchen took a few steps forward, put the porcelain cup on the table, and gently took Sylvia into his arms, stroking her lower back with one hand and gently stroking her neck with the other: "I like you."

He knew that his words were like a "fuse" to Sylvia, but he still wanted to say it, not for anything else, just to repay her kindness to him.

Hearing Su Yuchen's voice, Sylvia's cherry-pink eyes first opened slightly, then narrowed, a touching blush emerged on her calm cheeks, and her soft body rubbed against his arms involuntarily.

"Chen, I..."

Kakaka... Chichichi—

A sharp sound came from the door, like the sound of nails scraping on a blackboard, harsh and unpleasant.

Su Yuchen shrank his neck, quickly let go of Sylvia and walked to the door. As soon as he opened the door, a small figure emitting pure white light rushed in and jumped onto the table nimbly. Its furry tail swayed left and right and it meowed at Su Yuchen. The two pink pads on its front paws were spread out in Su Yuchen's sight, waving up and down, as if craving for something.

Su Yuchen was stunned for a moment. Why did Raorao's cat come here?

After closing the door again, Su Yuchen just walked to the table when the beautiful white cat with a tuft of red hair between its eyebrows excitedly "meow meow" and jumped into his arms, sniffing, scratching and rubbing...

The corner of Su Yuchen's mouth twitched, and he immediately realized what was going on.

Yes, a cat’s estrus period doesn’t end in one day.

The reason why she ran from Raorao to me was simply because I was a man and the white cat in her arms was a female.

Taking another look at Sylvia with rosy cheeks, Su Yuchen felt uneasy. The current state of the succubus and the white cat... was not right!

After thinking about it, Su Yuchen sat on the chair, feeling the hot temperature of the white cat with his palm, and began to use magic to help her relieve her "meow meow meow" state.

A white cat with cloud wings.

Su Yuchen looked down at the white cat, which was much quieter than before. While stroking her soft white fur, he said to Sylvia, "This is the cat that Raorao raised. It's the only white cat with cloud wings in the world."

"Raised?" Sylvia blinked and looked at Su Yuchen in confusion. Isn't this cat Bai Raorao... She could tell it at a glance.

Ming Mingchen is so powerful, why can't he see through the identity of this white cat?

it's wired.

"Yeah." Su Yuchen nodded: "I met him once in the library before, he was very clingy."

"Estrous season." Sylvia said suddenly.

"Yeah." Su Yuchen looked down at the cute way the white cat hugged his left hand with its four little paws because he stroked its belly, and couldn't help but smile: "It's quite cute."

"Meow~"

The white cat seemed a little embarrassed and rubbed its cute little head on the back of Su Yuchen's hand. As it smelled the air, it stretched out its pink tongue with tiny barbs to lick his fingers.

"hiss……"

Su Yuchen couldn't help but shiver. He didn't feel any pain when being licked by the barbed tongue. Instead, he felt a tingling sensation going from his cervical vertebrae to the top of his head, which was a bit strangely comfortable.

Sylvia looked at the white cat with a little envy. She also wanted to lie in Chen's arms and be teased like this... By the way, she could transform herself.

then--

puff!

Su Yuchen felt a flash of cherry pink light before his eyes. He looked up and saw a little devil about 30 centimeters long flapping its wings in the air and flying towards him.

"I...fuck!"

Su Yuchen couldn't help but let out a low cry, looking at Sylvia, who was flying around him with devil horns, wings and tail, with a strange expression: "Are you Sylvia? Can a succubus become smaller? No way!"

"I am part elven."

Although Sylvia was curious about why he asked "Are you Sylvia?", she didn't care too much and held his nose with her small hands, then rubbed his nose with her cheek happily.

The next second, Sylvia suddenly felt her tail being patted. She looked down and saw the white cat in Chen's arms staring at her fluttering devil wings with its azure vertical pupils, curiously, and its eyeballs moving with the wings.

For cats, small objects flying around can easily arouse their curiosity.

So Sylvia let go of Su Yuchen's nose and flew around in front of Bai Raorao. She played more happily as she watched her two little paws flapping around trying to catch herself.

"Meow~woo~"

The white cat Bai Raorao left Su Yuchen's arms, jumped onto the table and squatted down, slightly arching her back, staring at the little devil Sylvia intently with her deep blue eyes.

"Meow~woo~"

Listening to the white cat's lowered voice, Su Yuchen said to Sylvia helplessly: "Be careful or I'll eat you in one bite."

"No." Sylvia flew to Su Yuchen's head and hooked her little finger at the white cat.

When the white cat lowered her body and was about to pounce, Su Yuchen quickly held her head down and said, "You have to get along well with me, okay?"

"Meow~Meow~" The white cat immediately became docile and licked Su Yuchen's palm, no longer making any attacking gestures.

"Not in heat anymore?" Su Yuchen looked at the white cat with a smile.

"Meow~" the white cat called shyly. The master's magic power was super comfortable and it was easier for him to suppress his restless body than himself. It was super super super powerful.

The white cat docilely nudged Su Yuchen's palm and meowed from time to time, which was so adorable.

"Chen." Sylvia flew to his other hand, held one of his fingers with her small hand, pulled his hand to the table and spread it out, then she curled up and rested her head on his palm, feeling his warm palm and stretching her limbs comfortably: "Chen, it's so warm."

Su Yuchen looked at Sylvia in his palm and joked, "You really scared me just now. If you hadn't changed in front of me, I wouldn't have realized it was you."

Sylvia sat up in his palm, her two plump legs spread out in an "eight" shape, looking up at Su Yuchen, who was like a giant to her at this moment: "Why? Do you think I've changed a lot?"

"That's not the case." Su Yuchen shook his head and looked at the shrunken Sylvia: "Maybe she just didn't react for a while."

Sylvia glanced at Bai Raorao who was still rubbing Su Yuchen's hand. Is this the reason why Chen couldn't see through her?

Unlucky?

As Sylvia lowered her head to think, Su Yuchen looked at her small body. She had elf blood? Would elves mate with demons?

and……

"Why has your school uniform also become smaller?" Su Yuchen asked curiously.

"Chen wants to see me without clothes?"

"..."

Su Yuchen helplessly looked at the little succubus whose head was full of yellow waste. Hmm! Isn't it normal for clothes to become smaller? Otherwise, what if she is exposed?

Don't ask, it's not a big deal.

Su Yuchen pressed Sylvia's cheek with his thumb, and Sylvia quickly hugged him with both hands: "Chen's fingers are so big, I can't hold them..."

Sylvia's cherry-pink eyes glowed with a strange light. She opened her little mouth and sucked a small piece of flesh on the tip of her finger. Then she stared at his finger for a long time, then looked at herself at this moment, and finally looked up at Su Yuchen: "Chen, I think..."

"No! You don't think so!" Su Yuchen decisively interrupted her voice: "Stop talking."

"Chen, same as me."

"Hehe..." Su Yuchen looked away and looked at the obedient white cat, and quickly scratched her chin: "I'm not a pervert...right?"

"Meow~"

The white cat meowed, licked his palm with its tongue, and then turned its head to look at the porcelain cup beside it: "Meow~"

"thirsty?"

"Woo woo~" the white cat let out a low cry. Its body had been feeling hot and it had lost a lot of water.

Su Yuchen looked at Sylvia: "Do you have an empty container?"

"I don't mind her drinking from a cup." Sylvia looked at the white cat. After all, she was Chen's 'own cat girl'.

"Does Chen mind if she drinks from a cup?"

"I don't mind." Su Yuchen looked at the white cat and thought that if it was a wild cat, he would definitely mind, but for this beautiful white cat... his tolerance was quite high.

"Meow~"

The white cat sniffed with its little nose, came to the porcelain cup that Su Yuchen had just used, looked at the mellow milk in it, and licked it with the tip of its tongue.

Su Yuchen suddenly asked: "It seems that cats can't drink milk..."

“I’m not a cow.”

"Meow?"

The white cat turned its head, and stared at Sylvia with its sapphire eyes. What did she mean by that? !

Su Yuchen touched the white cat's head and said, "Drink it, it's okay."

"Well, you have to drink it sooner or later anyway," said Sylvia.

The white cat looked at Su Yuchen and Sylvia in confusion... If it didn't understand, it would stop thinking about it. It crawled down again and licked the mellow milk in the porcelain cup in small sips.

"I've made an appointment with Yae Mio to meet at the library." Su Yuchen stretched out his hand to play with the white cat's furry tail, and said to Sylvia in his palm: "Help me control her."

Sylvia flew in front of him: "Sex..."

Su Yuchen stretched out his finger and flicked the little girl lightly: "Not a slave in that sense, but the kind that makes her obedient and won't betray me."

Sylvia held his finger: "Just be obedient, right?"

"Yes, but..."

"Chen, just leave it to me."

Su Yuchen opened his mouth and thought, forget it, just let her go.

Anyway, the master-slave contract magic in that area is not about turning the other party into a pleasure machine whose will is overwhelmed by desire.

"But even if it's you, to cast a perfect mental magic, you need the opponent's mind to have a flaw, right?"

"Well... after all, it is another person's spiritual world. If the other party fully cooperates, there will be no flaws in the future... If I force it, I will destroy the other party's soul."

Sylvia lowered her head a little embarrassedly. Su Yuchen could understand. After all, although she was a demon king, her succubus-related powers were awakened quite late.

"Sylvia, you are so good, there will be no problem." Su Yuchen praised, and saw the white cat running in front of him and meowing, as if saying that I am also very good.

Su Yuchen took out a tissue from his pocket and wiped the wet milk drops from the corner of the white cat's mouth: "Are you full?"

"Woo~ meow~"

The white cat squinted its eyes, and waited until Su Yuchen wiped his mouth, then suddenly jumped into his arms, stretched its limbs, and looked so relieved that there was nothing happier than this.

Su Yuchen stroked the white cat's soft fur and continued to say to Sylvia: "I know Yae Mio's flaws. She is a brother complex, and she and Yae Shinshin..."

Su Yuchen told Sylvia about the situation of the two siblings, and also told her about his plan to use the special hobby of Yae Shinto to make Yae Mio despair.

Sylvia, who had held Su Yuchen's five fingers, sat back in his palm: "I know what to do."

"I have another question." Su Yuchen looked at Sylvia: "I don't know if Yae Mio knows her life experience, so I have to find out this question first."

If Yae Mio didn't know about her relationship with Yae Shinkami, then if she knew now, she would be more surprised than upset, which would be difficult to deal with.

And if she knew all this, it would be much easier to corrupt her heart, as long as she knew that Yae Shinshin would rather play with any woman casually than touch her, and that he really liked the excitement of giving her to the so-called 'Crown Prince'.

Yae Mio could tolerate Yae Shinkami's bad attitude towards her, could tolerate Yae Shinkami having other women around her, and could tolerate Yae Shinkami asking her to serve His Royal Highness the Crown Prince.

But can we tolerate that Yae Shinshin did all this in the hope of finding a different kind of pleasure?

Yae Mio must have thought that Yae Shinshin had his own considerations and difficulties in doing these things, but she certainly could not have imagined that this was what he was thinking in his heart. He just wanted to make her feel cheated and that he himself had the special feeling of being cheated.

Sylvia looked at Su Yuchen's devilish smile and said, "He has this hobby, but he must be very uncomfortable inside, right?"

"Sure." Su Yuchen pinched the white cat's neck and said, "Who told him to kill my only precious sister?"

"He will definitely not stop here, so let's just get rid of him today..."

call out!

Before he could finish his words, the white cat that had been rubbing his palm affectionately suddenly jumped out, pulled the door handle flexibly with its two little front paws, and then rushed out through the crack in the door.

Su Yuchen was stunned for a moment. Why did he suddenly run away? Bai Raorao came?

"Want to chase?"

"No need." Su Yuchen looked at the time on his phone, and the bell for the end of get out of class rang outside the window.

"Yae Mio is coming soon."
