"Help—"
As soon as Raiha realized Yotsuba was serious, she knew she was in great danger and tried to scream with all her might, hoping a neighbor would hear and come to check.
Unfortunately, her plan failed completely. Only one word was uttered before Yotsuba reacted quickly. Her strong hand tightly covered Raiha's mouth, preventing her cry for help from becoming an unintelligible gasp.
"Good job, Yotsuba. It would be troublesome if someone came."
"Thank you for the praise, Master."
Her feelings were mixed. On the one hand, Yotsuba felt happy to be praised by Ren, but on the other hand, her conscience felt guilty for treating her own sister-in-law this way.
"..."
Ren ignored Yotsuba's inner conflict; he began to chant the activation incantation for the Divine Authority Book of Knowledge.
"Fairy tales, Facts, Myths, all are stored in my writings, all secrets gathered in my grasp, nothing can be hidden from my mind."
*BUZZ!*
The next moment, a book materialized in Ren's hand. This book was the manifestation of the Divine Authority Book of Knowledge, which had access to all knowledge in the world and would show the necessary knowledge for any problem presented by the user.
"Show me super strong hypnosis magic."
Except for Storage Magic, Ren never bothered to learn any other magic.
Why go through the trouble, when with his Divine Authority, he could instantly access and use all magic in human civilization through his Divine Authority?
*SHUAAA!*
The book opened by itself, its pages spinning rapidly before stopping on a page filled with complex diagrams and incantations. A high-level hypnotic magic that Ren needed now was clearly displayed before his eyes.
Ren then looked at Raiha, who was still struggling against Yotsuba's grip, his eyes narrowed with a threatening glare.
"Listen carefully, Raiha-chan. From this moment on, your life will change forever. Blame yourself for knowing something you shouldn't have known."
"Sometimes knowing too much is not a good thing. As the saying goes, ignorance is bliss."
Without giving Raiha a chance to react, Ren's hand holding the book lifted. Magical power flowed from the book, forming a complex light pattern in the air that went straight to Raiha's head.
"Mhmm..."
Instantly, Raiha's eyes, which were initially filled with fear and resistance, slowly became empty and unfocused. The hypnotic process that would change her life had begun.
"You can let go of her now, Yotsuba."
"Yes, Master."
Obediently, Yotsuba released her grip on Raiha. The girl now stood straight, but like a doll that had lost control. Her gaze was blank and vacant, expressionless, staring straight ahead without awareness.
"W-What does Master want to do to Raiha-chan? Does... does Master want to make her a sex slave too, like me?"
In her heart, Yotsuba still hoped her master would only erase Raiha's memory of this affair and let her go peacefully. However, considering Ren's perverted nature and insatiable lust, she knew that hope was very slim.
"It all depends on her answer later. As for what I want to do to Raiha... Yotsuba, do you object?"
"N-No! Not at all! Forgive my audacity, Master. I know I was wrong. I won't do it again."
Yotsuba shuddered under Ren's sharp gaze. Immediately, she quickly performed a dogeza, bowing her body until her forehead touched the wooden floor, willingly lowering her self-respect to avoid her master's anger.
Yotsuba couldn't imagine life without her master. Her sexual needs, which had been awakened and satisfied by Ren, had become an addiction that made her fear losing him.
"Mm. Know your place."
Ren stepped on Yotsuba's head with his shoe, pushing her forehead harder against the floor.
"Never dare to dictate my actions."
Keeping his foot on Yotsuba's head, he shifted his gaze to examine Raiha, who was still in a trance.
"Not bad. Long hair and quite full breasts. That's my ideal type of woman. Although her face is not as beautiful as the Nakano quintuplets or the other women in my harem, Uesugi Raiha cannot be called ugly. Her beauty is just average."
His eyes scanned the girl's body from top to bottom. Ren treated Raiha like an item being appraised in a display case.
"Hah... Hah... Hah..."
Under Ren's foot, Yotsuba remained silent and obedient. Strangely, this degrading and humiliating treatment actually aroused her. The proof is that she can feel the moisture starting to soak into her panties, a body reaction she couldn't lie about to the violence and dominance shown by her master.
"Raiha. Do you have a boyfriend?"
"Yes. He's a senpai in the basketball club at my school."
Hearing Raiha's honest confession, Ren's eyebrows furrowed.
For a Japanese high school girl, having a boyfriend is normal. However, the reality of free socialization in Japan is almost equal to Western culture. It is not surprising that many female students have lost their virginity even before graduating from school.
This social phenomenon often made it difficult for Ren, who had a special preference for only being intimate with virgins, to find new candidates for his harem.
"Are you still a virgin?"
"No. Last week I gave my virginity to Tanaka-senpai as part of the celebration because the basketball club successfully qualified for the national competition."
"Tsk. Just as I suspected."
Raiha's answer was in line with Ren's expectations.
Finding a woman who still retained her virginity until adulthood in Japan was like looking for a needle in a haystack—perhaps even rarer than a panda. Except for women with less attractive appearances, introverted personalities, victims of bullying, nerds, or other negative factors, it was almost impossible to find a beautiful girl who was still a virgin in Japan.
The case of the Nakano quintuplets and Kikuchi Sonoka, who remained virgins until entering adulthood, was a very rare exception.
"Boring."
Instantly, all of Ren's interest in Raiha vanished.
"Letting her go just like that is too easy. Hmm... What should I do?"
Ren rubbed his chin, his sharp eyes staring at Raiha's body, which was still frozen in place. His mind worked quickly, looking for a way to exploit the situation. A moment later, a wicked idea formed in his mind. A thin, unpleasant smile appeared on his lips.
"Alright, let's do that."
With the help of the Divine Authority Book of Knowledge, which was still open in his hand, Ren uttered another incantation.
A subtle magical power enveloped Raiha. This time, the effect was more specific. Her consciousness was fully awake—she could see, hear, and understand everything around her. However, she could not control her own body or utter a single word.
"How long are you going to kneel, Yotsuba? Come on, show your hidden slutty side to your cute sister-in-law."
"Yes, Master~"
Obeying Ren's command, Yotsuba rose from her dogeza position, her eyes, which were previously full of remorse, now sparkled with lust and blind obedience.
The scene that followed was a deliberate exhibition of depravity in front of the helpless Raiha. Ren pulled Yotsuba into his embrace, and they kissed lustfully, right in front of Raiha's wide-open eyes.
Ren roughly tore Yotsuba's shirt, allowing her full breasts to be exposed. At the same time, Yotsuba skillfully unbuckled his pants and began to give him foreplay with her mouth, while her gaze shyly looked at Raiha's eyes, which were filled with horror and silent tears.
Without much further ado, Ren then flipped Yotsuba's body and bent her over the dining table, entering her from behind with a rough thrust.
Every moan, every gasp, every slap Ren gave to Yotsuba's butt—it all happened in very close proximity to Raiha. She was forced to witness every intimate and shameful detail of her sister-in-law's affair, unable to turn away or close her ears.
It was a cruel psychological torture, a display of Ren's absolute power over the two women, one by exploiting her obedience, and the other by imprisoning her consciousness.
