The dining room was vast and lavish, its sheer size impossible to ignore. The ceiling and walls were painted entirely in gold, layered with ornate decorations crafted from pure gold alongside intricate carvings that drew the eye. Multiple chandeliers hung overhead, all forged from gold as well, inlaid with what appeared to be rare crystals that caught the light and scattered it across the room, making the entire space look even more extravagant than it already was.
The room exuded a sense of opulence, and the mix of light and gold made it painfully bright, as if the owner had done it on purpose to blind poor people seeing it for the first time, dazzling them with their ridiculous wealth.
An extravagant meal, so large that no one could ever hope to finish it, was piled atop expensive-looking plates, each dish more excessive than the last.
Dozens of maids and butlers stood to the side, alert and attentive, patiently waiting to serve at the slightest gesture.
"Please enjoy yourself without holding back." A handsome middle-aged man with long crimson hair spoke to Yusuke. Zeoticus Gremory smiled as he added, "You have only just come to the Underworld, so you are in an environment you do not understand. If there is anything you want, please say so to the housemaids without reserve. They will prepare it right away."
He was truly satisfied with this future son-in-law of his. From what he had seen during the battle against Riser, the boy was strong, dependable, and decisive when it mattered. If there was one thing he could complain about, it was the fact that he was human.
It was not that he looked down on humans, but a human's lifespan was pitifully short compared to that of devils. Zeoticus Gremory did not want his daughter to suffer the sadness of barely growing up, only to find her husband turned into an old, senile man after a mere hundred years.
"Thank you for your concern, Lord Gremory," Yusuke said as he picked up his knife and fork, eating at a measured pace while politely expressing his gratitude.
"You do not have to be so polite, hahaha. After all, we will soon be one big family!" Zeoticus laughed cheerfully. His gaze moved to Yusuke and Rias sitting next to each other before he added, "I would like it more if you were to call me father in the future."
"Don't you think so, Venelana?" He turned to his wife as he asked.
"Indeed, you can also call me mother," Venelana agreed with her husband. She added with a teasing smile, "You can also call mommy if you want."
Though she would rather he call her Onee-chan. It would make the age gap between them feel much smaller.
'How much I hate sitting next to this man! If only I could be the one next to Yusuke, or better, sitting on his lap and sharing the same seat. How romantic~!' ran through her mind as she cast an envious glance at her daughter.
"That's right, you can also call me Onii-san!" Sirzechs said cheerfully. He had a rare free day and was also present, just as easygoing as his father. He looked genuinely excited as he observed his future brother-in-law, clearly pleased to finally meet him in person.
Grayfia sat next to her husband, eating in silence. She did not seem interested in engaging with any of the commotion around her. In the past, she would usually be wearing her maid uniform, working alongside the maids, since it was her hobby. Lately, however, she no longer showed any interest in continuing this.
This naturally sparked curiosity among those around her, but she only said that she simply did not feel like doing it anymore. All her energy was quietly devoted to something else, kept entirely secret.
Akeno and Koneko sat next to each other on the other side of Yusuke, eating in silence as well. Akeno focused on replenishing all the fluids and energy she had lost during her intense 'exercise,' while Koneko tried to ignore everything around her, feeling increasingly uncomfortable.
'Is this how a family is supposed to be, or is it just Rias's family that's like this?' Yusuke felt overwhelmed by their overly enthusiastic attitude. They were far more welcoming than he had expected.
He had never experienced what it felt like to have a real family. The concept of family had always felt foreign to him, even though he had parents.
Watching how harmonious the family before him was, he honestly felt some envy toward Rias.
"Mother, Father! Stop this shameful behavior!" Rias exclaimed, slamming the table as if she could not bear her parents' words. Her face flushed red, but in her mind she thought, 'Good job, Mom and Dad! Onii-sama too! As expected, the only people I can truly count on are my family!'
"Hahaha, our little Rias is getting embarrassed!" Zeoticus laughed once more before picking up a goblet and drinking the wine. He added, "Although this may look like we are moving a bit fast, since you have canceled your engagement with Riser, we must proceed with the new one."
With a helpless and resigned expression on his face, he continued, "These nobles have been getting noisy recently. Your brother and I have had to put in so much effort just to make them quiet."
Yusuke listened quietly while eating slowly. He took a sip of fruit juice and pondered, 'Why would other nobles interfere in the internal affairs of another noble house, a house that produced the strongest Maou no less? Does this make any sense?'
[Yes, even if it is to preserve the bloodline of pure noble Devils, this still does not make any sense. Perhaps he is talking about noble Devils from the same faction as them.] The system answered, then her tone immediately changed. [Wait, why am I even answering your stupid question? I am a system, not your portable spirit grandma!]
'You are completely useless to begin with. You should try to be a little bit useful,' Yusuke snickered mockingly. Then, suddenly, he felt someone touching his thigh. Looking down, he saw Rias's hand. 'What is she doing?' he wondered.
Looking at her expression, she still wore the same flushed and bashful look, but under the table, her hand was sensually caressing his thigh, slowly inching toward his 'little Yusuke'.
"By the way, Yusuke, have you ever considered becoming a Devil?" Sirzechs asked suddenly.
'Why are you asking me at a moment like this?' Yusuke forced a smile, trying to ignore the hand caressing his stiffening cock. He replied, "No, not really. I am satisfied with the way I am right now."
'Is this girl out of her mind, doing something like this here?!' He stole a glance at Rias, who kept her head low as if still embarrassed, but her breathing was quietly growing ragged. From his angle, he noticed that her other hand was actually moving slowly between her thighs. 'Are all these women horny perverts?' Yusuke thought, speechless.
'This is exciting! Seeing Yusuke so helpless is making me weirdly excited~!' Rias glanced at him from the corner of her eyes, her heart racing. She bit her lips to stifle the moan trying to escape, the intense waves of euphoria and ecstasy making her shudder violently, which she barely managed to suppress. One hand was caressing Yusuke's cock over his trousers, while the other was already touching her own pussy, caressing her clit through her panties.
She had never done something like this before, teasing her man and masturbating right under the watchful eyes of her family. The feeling was intensely enrapturing, unlike anything she had experienced before, almost as exhilarating as when Yusuke kissed her.
"Maybe you should reconsider the possibility. After all, a human's lifespan is short," he said, oblivious to what his sister was doing. "You would not want your loved ones to watch you grow old and die, right?"
"...I'll think about it," Yusuke answered with a forced smile. He lowered his head, turning his attention back to his plate, and reached down to grab Rias's hand.
If he let her continue stroking his cock like that, he would cum in his pants.
However, what Rias did next was completely unexpected. She grabbed his hand and quickly pulled it between her legs, trapping it between her thighs as she began grinding it against her pussy.
She was using his hand as a masturbation tool.
'Shit! Isn't she afraid of getting exposed? Fortunately, the table is high enough,' Yusuke thought, glancing at Sirzechs and Zeoticus, who did not seem to have noticed anything. He looked back at Rias, only to see her glancing at him with a lascivious, teasing smile before lowering her head again, trying to hide her euphoric expression.
[How could you allow a woman to use you like this? Smack the shit out of her!] the system shouted in his mind.
'Shut up. Who told you I am not enjoying this?' Yusuke retorted. The experience was thrilling, and the danger of being exposed made it even more exciting. 'If I were to get excited, would Sirzechs, Venelana, and Zeoticus explode in anger?' he wondered.
While he was thinking silently, he felt Rias's body trembling violently. Her legs clenched tightly around his arms as she came, squirting and wetting his hands. After the climax, her body slowly relaxed, and she slumped forward onto the table.
Thud!
"Rias?!" Sirzechs and Zeoticus reacted at the same time.
"Rias, are you okay?" Venelana asked, her voice full of concern.
"No... I am just... feeling slightly tired," Rias replied without looking up. She did not want them to see the face she was making at that moment. 'This feels so good! It is pure bliss! What would it feel like if I had sex with Yusuke in a situation like this? Ahn! Just imagining it makes me feel so horny all over again!'
She was awakening her exhibitionism fetish.
"If that is the case, how about you go back to your room and get some rest," Venelana said, glancing at her oddly. Just a few moments ago, she had seemed perfectly fine.
"Yes, Mother," Rias replied in a weak voice.
"Ojou sama, allow me to help you," one of the maids stepped forward, but was stopped by Akeno. "Rias, I will help you back to your room," Akeno said. She stood, walked to Rias, and helped her up, giving Yusuke a teasing smile and a wink as she did.
[She knows!] the system said.
'Yeah, she knows,' Yusuke replied.
After dinner, Yusuke finally returned to his room, having turned down the invitation from Zeoticus and Sirzechs to drink with him. The two were reprimanded by Grayfia and Venelana for asking a minor to drink with them.
After changing his clothes, he headed to the bathroom to take a bath.
The bathroom was far larger than his own and even had a hot spring in the center.
"Rias's family sure is unique, but they are not bad. It is nice to feel welcomed by someone other than yanderes," Yusuke thought aloud while rinsing his body. "She has such a harmonious family. Zeoticus and Venelana really seem to love each other, especially for a couple married for political reasons."
[Who knows? You cannot say for sure.] the system said suddenly.
Clack!
"What does that mean?" Yusuke asked, taken aback by the system's words, but he was interrupted by the sound of the door opening.
