After Stealing Hero's Mother, I Reincarnated in the Fantasy World!

"I will take your silence as a sign that you have forgiven me. Then I enter, sister."

When the door ajar, Amelia, still fondling Rain's cock with her breasts, realized the gravity of the situation and shouted out in a panic.

"Stop!"

Those words caused Cale's body to instinctively freeze in place, never letting him enter the room.

"Did I make you angry again?"

With a tinge of pity, he asked.

"Cale, I'm in the process of conducting an important Mnhhhh~... experiment right now, so let's talk at home."

As curious as he was to look inside, Cale hesitated to do so because of his older sister's stern tone for fear of messing something up again.

"Sorry, I'll see you at home..."

He closed the door and, fighting the uneasiness in his soul, wandered down the hallway.

When the click of the knob sounded, Rain could no longer contain his arousal and it exploded with his hoarse moan of pleasure, releasing a load of hot cum directly onto Amelia's face.

She, still distracted by her brother's interference, was unprepared for it, so only confusedly accepted his charges one by one.

As the raging arousal in him subsided, his semen, which had completely flooded her face and even gotten into her mouth, was already dripping onto her breasts and rolling right onto the floor.

At that moment, Rain heard the system sound again.

[Extra Quest]

[Help Amelia with her research and expand her horizons.]

[Reward: Alchemy knowledge of rank 5.]

[Penalty for failure: ---]

[Time limit: one hour]

[1/1]

'Huh? Was that enough to complete the quest?'

Reading the description once more, Rain only felt more puzzled.

'Sometimes it's hard for me to understand how the system evaluates it...'

[Do you want to accept the reward?]

Rain didn't take it right now, focusing on Amelia.

When she came to, she looked at her breasts, covered in his semen, with obvious irritation, as if regretting that so much valuable material had been wasted.

Amelia collected all of his cum that had accumulated in her mouth and then stuck out her tongue and let the cum roll down it directly into the vial she had just pulled out.

'Okay, that looked pretty damn hot and now I understand what the quest was about.'

Rain admitted, continuing to watch her.

After that she did the same with the remaining cum on her face and breasts. When she finished, she realized that her panties were very wet.

'I'm so wet... is it because I've been under so much stress at work and at home lately?'

Looking at the young man in front of her, in whose eyes she could still read desire, Amelia sighed.

"The final meeting about yesterday's incident in the rift is about to begin and it would be best for you if I were there and could tell your side of the story."

Her words made Rain test her level of lust.

[Lust 20↓]

'Her level has dropped... did it happen because of her brother?'

Rain frowned slightly.

It would be tedious to raise it all over again, and if what she'd said was true, he really should have let her go. Besides, having already started their relationship, Rain didn't see the point in rushing into it.

'She's obviously not satisfied... I should come to her when she loses her patience and is ready to go much further.'

As he was about to leave, something on her desk caught his eye. It was the object Amelia had been holding when he first entered the room.

Out of curiosity, he walked over and picked it up.

"Hey, that's not yours!"

"That's why I took it."

Amelia threw him an odd look, but Rain paid no attention to it as he considered the object in his hand.

It was about the size of half his palm and had a streamlined shape. It was hard to tell from its appearance what it was used for, so Rain asked.

"What's that?"

"...this is our new invention, a compact mana wave detector. Right now it's just one of the prototypes and it has some drawbacks."

"The mana wave detector?"

Rain found a button on this device and pressed it.

*Bzzzzz*

There was a muffled buzzing sound, and Rain felt a vibration in his hand.

They stood in silence for the next minute, broken only by the low buzzing sound.

"...Why are you looking at me like that? …And what is that expression on your face?"

Asked Amelia, feeling his strange gaze on her.

"Just thinking about something... you don't mind if I take it, do you?"

After hesitating for a few seconds, she gave her answer.

"Of course. It's not something very secret, but I still don't recommend you spread it around too much."

"Don't worry, I'll find a good use for it."

He headed for the exit and, opening the door, added without turning around.

"Say hi to your brother for me."

As Rain walked down the long hallway, the cool air made him feel the tension in his groin again.

'I'm still not satisfied.'

Having come to this conclusion, Rain began to think about how he could deal with it, and soon a great idea came to him.

'It's time to visit my sweet little sister.'

With those thoughts in mind, Rain turned on the ring communicator and finding Liana there, texted her asking where she was now.

No more than ten seconds later, he got a reply with the number of the office she was in. When he remembered where it was, Rain went there at once.

'I'll have to find out what she wanted to talk to Ael about so badly.'

After walking a few blocks and climbing the stairs, Rain stopped in front of the office. After comparing it to the one Liana had mentioned, he opened the door. Or tried to, because he'd been forestalled.

The door swung open and a woman stepped out. She had a tired look in her eyes, and her hair was slightly disheveled. On her blouse hung her badge, which was turned sideways, making it hard to read the text on it.

"Let me help you..."

Rain adjusted her badge and discerned her name on it.

"...Ms. Audrey."

"Thank you."

Audrey replied, a little embarrassed to be in front of a student like this. She was about to walk past him as she adjusted her blouse, but something suddenly caught her eye and she stopped short.

"Wait, I've seen you somewhere before."

She stared at his face, trying to remember why he looked familiar. Then, as if the puzzle was finally coming together in her head, she exclaimed animatedly.

"You're that student!"

Rain gave her a questioning look.

"Ah, sorry, it's just thinking out loud."

Quickly Audrey corrected herself and strode forward down the hallway, muttering something to herself.

"Seeing him reminded me that I wanted to ask Amelia not to hit on him too hard. By the way, I should stop by her place."

After looking at her receding figure for a couple seconds, Rain entered an empty office, finding only his sister Liana there.

She was in the same uniform he had seen her in this morning, a clean white shirt and a stylish skirt above her knees. The only difference in her was her disgruntled look.

"Do you flirt even with older women?"

'I really just wanted to help her...'

Despite this, Rain didn't deny or confirm it and simply replied with a silent smile before asking.

"Anyway, who is she?"

After staring at him displeasedly for a while longer, Liana finally replied.

"As far as I know, she'll be our teacher next year. She teaches magical engineering in the upper courses, though right now she spends most of her time parsing papers."

Liana paused and looked at his reaction before uttering.

"You're interested in her?"

"Why do I need her when I have you?"

Rain replied with a chuckle.

"Liar, if you thought that way, you wouldn't have so many women around you."

Liana pouted and turned away. But even knowing that this answer wasn't completely true, she couldn't hide her smile upon hearing it.

'She's as cute as ever.'

As if not noticing her smile, Rain shortened the distance between them.

"Don't worry, you're really important to me. After all, we are one family."

These words seemed to dissolve any remnants of displeasure in her, and she turned to him.

"Why did you come...?"

Liana didn't finish as she saw the look in his eyes. In the short time they'd been together, she'd learned to understand without words what her brother wanted.

"...Do you want to do it?"

"Yes."
