Reincarnated as a Son of the Sword Saint and the Sage

There is no need to hide the truth from her anymore. My sister seemed shocked when I directly told her who I spent my first night with. But then her dilated eyes contracted, and her lips curled to form a sneer. 

"Hah? What nonsense are you talking about? Has your head been hit by something so hard that you have become delusional?" She scoffed. "I know you loved Mom very much, but it is no time for jokes." 

"Do I look like I'm joking to you?" 

I told her those words with a dead serious face. My sister had a staring contest for a while and then eventually removed the scornful expressions on her face. 

"No way... Tell me that's not true, Raphael!" 

"It is true, Louise." 

Suddenly, a voice with a gentle tone rang behind my sister, which made her look back and see the one who invoiced that phrase. 

"Mom...?" Sister called Mom out with a weak voice. "What do you mean about that...?" 

"Mom meant that I had an affair with her, Sister." 

I answered her question instead of Mom. She seemed not to be listening to me, so I grabbed both her shoulders and forcefully made her face me. I then locked my gaze on her before I continued. 

"Sister, it might be hurtful, but Mom is one of my women." 

Once I said that, Sister lowered her head. A few seconds later, she raised her head as she flashed me a wrathful face. 

"I certainly had enough of this crap! Let me go!" 

My sister got angry and pushed my chest, which made me let go of my grasp on her shoulders. She stepped back a few steps and distanced herself from me. 

"I want to hear it from you, Mom!" She furiously looked at Mom. "Is what Raphael said true?! Or was he just lying?!" 

Mom took a sip of her coffee and then put her cup down on the glass table. She first put on a gentle smile before turning to Sister to answer her questions. 

"Louise, please calm down and listen to me, okay?" 

Mom calmly tried to cool off her daughter. Then, she graciously stood up and approached Sister. Mom slowly opened her arms, indicating that she wanted an embrace. 

Sister, who had been calmed down by Mom's motherly and persuasive voice, drew herself closer to her and utterly accepted Mom's tempting offer. 

(Mothers truly are amazing... To think that Mom could handle an enraged Sister that easily.) I thought inwardly. 

"Mom..." 

Sister mumbled as she was being pampered by Mom. She then tightened her embrace to feel more of her, squeezing her amples against the mountains. Due to that, Mom's succulent bosom was spread out and jutted out of her torso. I think you should take a look at

"There, there, Louise," Mom tenderly caressed Sister's head. "I know that might get mad at me. But I want you to know that all the things that Raphael said are true. I am having a relationship with Raphael, my son."

"But, Mom...!" Sister then gripped the dress of Mom. "He is your own son...! Your biological son, to be exact...! That is incest...! How did you make yourself commit such an immoral act...?!"

"I am completely aware of ethics, Louise. We completely knew that we were doing something taboo, but we truly loved each other." 

"But why...?" 

"Raphael confessed his love to me. He told me that he saw me as a member of the opposite sex, and his love was not only familial, but also romantic. But you know what, Louise?" 

"..." 

"When he told me he loved me as a woman, I actually felt very happy. Do you realize why your Mother and I gave birth to Raphael when this family actually doesn't need to have a male member?" 

As she was saying that, Mom unwrapped her arms around Sister and held her shoulder to face her. Sister was seemingly left unsatisfied, but she stayed focused since she had to hear what Mom would say. 

"We procreated Raphael for the reason of... making him a suitable man to satisfy my carnal desires. That means, even before he was born, I had been seeing him as both my child and a man from the start." 

"Mom... are you out of your mind?!" Sister lost her temper and furiously loosened herself from Mom's hands before stepping backward. "Do you really hear what you just said?!" 

"I am very sorry, Louise, but this is the real me. I really don't want to hurt you, but I love Raphael, and there's nothing that can stop us from loving one another. I apologize for having such an immoral mother." 

"Disgusting! Really, real mother-son incest?! Not even in the slightest that I think of it happening in this world! You two really are a mother and son! No wonder Raphael became a degenerate to that extent; it is actually running through his veins! What the tree is, so is its fruit!" 

"Louise!" 

Unable to bear the behavior that Sister had been displaying toward Mom, Mother stood up and began reprimanding Sister. Thankfully, I had erected a barrier so that no one was going to intrude or hear us here. 

"You have gone too far! Do not disrespect your mother that much! Apologize to her right now!" 

"You are another too, Mother!" She answered back. "Why are you letting Raphael do whatever he wants?! He is literally fucking your own wife! Are you also defending him?!" 

"Sister." I called her out, which made her glance in my direction. "For your information, my first night was actually a threesome. You should know who the other person was." 

When I revealed that, Sister looked at Mother. But Mother said nothing and only provided her with a smile. However, that was more than enough for Sister to learn what she wanted to indicate.

"You...!!!" 

In a flash, Sister quickly drew out her sword from her magic bag, which was hanging on her waist, and slashed the ultramarine blade at me at an incredible speed. From the activation of the sword's Absolute Severance, I could guess that she was trying to strike her weapon with an intention to kill.
