She looked around and saw Kaori's bed in a mess with wet stains drying on the sheets. The smell of sex clung to every surface, from the rumpled blankets to the walls and floor.

Her gaze slowly scanned the room, taking in the details of the furniture and decorations before finally settling on Kaori. She closed her eyes and took a few deep breaths to steady her nerves, then opened them again and looked at Kaori's way.

"You know, I saw Kai, mother Nuan, mother Ying doing something inappropriate, and then yesterday night I saw Kai came in your room and heard those inappropriate voice, and now this inappropriate smell in your room, how do you gonna explain this to me?" Xin had a stern face as she asked Kaori.

Kaori at first was surprised to hear that Kai had sex with Nuan's mother and Ying's mother, then her face went pale as she heard her older sister ask for an explanation.

She didn't know how to explain this, she only wanted to grow strong, but she knew her potential and knew there was no way to grow stronger without any good resources or techniques.

When she got good technique it was sexual, at first, she didn't want to do anything with this technique but when she saw her little sister having sex with Kai, she thought that she wouldn't mind if she grew stronger by making Kai her dual clutivation partner but she still resists that idea.

However when she heard the threat that would be coming over them, she thought that she needed to become strong by whatever means, that's why she had sex with Kai, and now things came to this.

However, Kaori was surprised as she thought in this house everyone had sex with Kai, leaving only her older sister Xin and little sister Chenxi.

"Are you going to tell me or not?" Again Xin asked with more seriousness and authority in her voice.

Kaori jumped in surprise as she heard her older sister's voice which was serious and this was the first time she saw her sister like and as Xin asked her again, Kaori couldn't handle the pressure and told everything to Xin.

Xin heard and her mind blew in shock as she stood there for a while before she left Kaori's room.

"Breakfast is ready, go to kitchen get it yourself," Said Xin leaving for Kaori's room.

Kaori sighed as her older sister left but then she heard her voice again and Kaori jumped up because of surprise.

"Give me that dual cultivation book," Xin asked as she stretched her hand.

"Okay, Okay," Kaori hurriedly said and she turned to find the book, after a moment she found the book and gave it to Xin.

Getting the book, Xin left Kaori's room and headed to her room.

Behind her Kaori fell on the floor as she felt too much pressure from Xin today.

"Its really bad that i did something that with brother, even let him cum inside me, i shouldn't have done that," Kaori spoke to herself as she regret her decision now but then she frowned.

She felt that her power grew, so she immediately get out of her room and went outside, and she saw a very thick trunk of the tree, and then she used her full power to punch the trunk and she made a dent in this thick trunk.

"I became strong," Kaori's eyes wide opened in surprised as she said.

Xin's room was illuminated with a warm yellow light that reflects off of the cream-colored walls and white ceiling. A large rug of colorful geometric patterns lies in the center, surrounded by luxurious furniture and various pieces of art.

A few windows let the natural light stream in, casting its rays across the room. Various elegant pieces of decoration were situated throughout the room, lending an air of sophistication.

Xin get inside her room and sat on her bed and looked at the book, she opened the first page of the book and saw a naked woman and a man.

She went to another page and as she read her face became red because of embarrassment, she wanted to close the book but the idea of doing all of this act with Kai made her turn to other pages.

Xin loved Kai for a very long time but the fact that they were sister and brother stopped her from doing anything about her love. She kept her distance from Kai and never tried to interact with him more than she need to be.

However, now her little sister and two mothers got involved with him sexually and she also saw Mother Ying and Mother Ying confessing their love and Kai also confessed to them that he loved them.

After witnessing that, Xin also wanted to confess her feelings but she didn't know how as she always made distance between her and Kai. Now she couldn't just go to him and say I love you.

She needed to make her distance from him shorter and try to develop feelings but she didn't know how she should do that, but now this book, this dual clutivation book might help her.

Although she wanted to give her first time to Kai when she confessed her feelings and Kai returned those feelings but she doesn't know how to do that.

So she decided that she would give her first time to him in the name that she wanted to grow strong, as she and he would do the more intimate thing, surely a feeling might develop inside Kai and he would come to love her.

Xin thought this as she got ready to do this. It would be too embarrassing for her but she was a master at hiding her embarrassment and acting cool without much problem.

"So taking a man thing in mouth can also simulate them, and this... This is forbidden knowledge of sex, really doing this can make girls stronger... Or Kai just give them to satisfy his own lust?" Xin wondered about this but she didn't think much as she continued reading the book and understanding all this sex knowledge.
