Chương 50: Even the devil needs to sleep early
Unlike before, her dress had changed and become more open.
Or rather, she was wearing nothing but lingerie!
Her taut and plump body was wrapped in see-through pink lingerie.
Nevertheless, her hair was still tied in a perfect twin tail, making him wish to hold her twin tails from behind, riding her from behind like a horse.
Yet, he quickly realized the seriousness of this problem!
He got an erection from his sister-in-law!
"Serafall-sama! What are you doing here?!"
He quickly pushed her away like she was an evil spirit who pulled him into the abyss. His heart was also beating so fast, but he wondered why his little Riser was so courageous that it still stood up without bowing down, especially in front of the presence of Maou Leviathan.
Serafall was in a daze as she was pushed by him and landed on his soft bed, but her eyes kept staring at his nether region, murmuring how her little sister could handle such an enormous beast.
"Serafall-sama, what are you doing here? Have you gotten lost? You should go back to your room."
Riser didn't think Serafall had fallen for him. If she could have fallen to him so easily, there was no way she still kept her virginity until now. There should be something hidden. Something that she wanted to do while wearing that see-through lingerie when she came to his room.
This something definitely wasn't simple, and he wasn't going to be fooled.
Frankly, even if Serafall's appearance was so seductive and sexy, he had been baptized by many women after he became a devil, so he could calmly face this situation and, as expected—
[Your sister-in-law comes into your room]
[What will you do?]
[Option 1: Kill her and burn her corpse. You will receive an "Absolute Burning"]
[Option 2: Force her to have group sex with all your peerage members and little sister. "You will receive "Unlimited Stamina"]
[Option 3: Refuse her. You will receive an "Agriculture Mastery"]
"..."
While he was speechless, he knew that he could use the system to guess the intention of the target. It was like how, in the beginning, when he was asked to divorce Rias.
The meaning of that option meant that no matter what, it was impossible to force their relationship.
That was the case with his current situation.
Why did the system tell him to refuse Serafall's advance?
It definitely had nothing to do with the fact that she might have an interest in him.
Instead, she was going to test him.
There is only one truth!
"What's wrong? You seem to be so excited there." Serafall smiled mischievously like a child as she pointed at his nether region. Though, inwardly, her heart was beating so fast, watching such a brutal beast born under his pants.
"...Sona will come back tomorrow. Of course, I am excited."
"....." Serafall.
"Serafall-sama. No, Aneki. I will forget this, so please return to your room."
"If I don't?"
"Then, I will go out and sleep outside. You can sleep inside my room."
Riser didn't waste his time and left as soon as possible.
"You won't regret it?"
When he was about to leave, Serafall asked him while looking at him curiously.
"I am not someone who is going to jump into the skirt of any girls I see, especially when you are my sister-in-law. I don't want Sona to be sad."
If it was another woman, then Sona might be okay, but her older sister?
There should have been mental preparation, and he didn't want to bet himself on his "Sex Mastery." After all, Serafall was one of the strongest devils in the world, so even if she was a virgin, her experience in fighting was rich.
Wrong move, and he would be frozen to death.
Moreover, as he had said before, he wasn't a man who would jump into the skirts of others, especially when he knew that this was a trap.
Instead, he was the type that let the woman jump into him.
So, there was no hesitation, and he was decisive.
Watching Riser leave without hesitation, the smile on Serafall's face changed and became thoughtful. The system was correct since her reason for coming to his room was to test him.
As Sirzech had said, it was weird for Riser to ask Sona to marry so suddenly.
Even though everything was also partly due to their parents, who asked them to marry as soon as possible, Riser also probably wished to use her to protect him, especially after he divorced Rias Gremory, the most loved little sister of Sirzech Gremory.
Using her as backing, Riser didn't need to worry about his safety.
However, even if Serafall knew that she was okay since her little sister had chosen him, and she could tell that Sona loved him too, she wanted to test him.
Serafall wanted to see what kind of man Riser was and whether she could entrust her little sister to him, and as expected, while he was a bit naughty, everything was still acceptable, especially when he refused her and clearly told her that they might make Sona sad.
Frankly, if he jumped into her and tried to do something lewd to her, she would fight him hard. She might not kill him, but she was going to give him a painful lesson.
So, right now, she was glad.
She was glad that Sona chose the right person, and she was glad that she supported their marriage.
Serafall smiled as she lay on his bed. Riser had just slept on this bed and used this pillow, so his scent still remained until now. His scent was nice; it was a little smoky, deep, spicy, warm, and manly.
It was a nice scent that made her press her face into his pillow as she inhaled his scent so deeply.
"Ha... ha... ha... his scent is so good~!"
Still, Serafall would be lying if she didn't feel annoyed as he had refused her. After all, she had many suitors for as long as she could remember, and all of them would beg her and do their best to make her fall for them, such as treating her gently, giving her various gifts, and many others.
Yet, he refused her without hesitation.
As for the reason for his erection, it was so perfect that she didn't have anything to argue about.
After all, Sona would go back tomorrow, and it was normal for him to have an erection for his wife, right?
Still, she pouted and felt a little annoyed.
Nevertheless, she felt a bit too lazy to go back to her room and felt that she might as well sleep in his room since it felt more comfortable. She closed her eyes and started to breathe softly as she fell asleep in his room, basking in his scent.

Meanwhile, Riser was a little helpless and thought of taking a cold bath to calm down his little Riser.
However—
"Riser-sama?"
He turned and saw his rook, Xuelan.
"Xuelan? What are you doing?"
"Oh, I have returned from the bathroom. What about you, Riser-sama?"
Unlike how she usually was, Xuelan let her shoulder-length black hair fall freely instead of tying it in Chinese-style buns. She also wore a red-colored dudou, making her trained body and shapely thighs seem lewd and arousing.
He felt his lips were dry.
He knew that it was wrong, and he knew that he might be frozen to death by Serafall, but it was also that woman's fault.
"Riser-sama?"
"Sorry, Xuelan, I have trouble sleeping. Can you help me?"
Xuelan blushed, feeling shy, but she nodded timidly as she tucked her hair behind her ear. "Then, come to my room, Riser-sama. I will help you to sleep."
"Okay, in exchange, I will help you to sleep too. You will sleep well tonight."
"Thank you, Riser-sama."
They knew that staying late wasn't good, so they helped each other to sleep early, leading a good and healthy life together.

It's a bit late, but should I make a list of his rewards?
