1.
Siwoo laid Yebin on top of the bed.
He forced her two arms up, restraining both her wrists to pin them above her head.
His lower body was stuffed in between her legs, rendering her unable to escape, while his other hand was kneading on both her breasts at the same time.
"Ah…euh…haaa…."
Even after numerous climaxes, his rod didn't turn any weaker, rather, it felt more robust than ever.
With his bloated cock, he stirred up Yebin's sensitive pussy while thrusting his hips even harder.
"Heuk…euk…!"
He didn't seem to think much.
Then again, he wasn't capable of doing that in the first place.
His treatment wasn't even halfway done yet.
That was why this phenomenon was something that could be classified as an unnatural one.
All he could think about was; there was someone beneath him, her face was pretty, her tits were big, she seemed to be an Asian, his hips were moving, his knees felt soft and he felt good from all that.
He could only recognize sequences that were made from short-length information each, unable to process those information into a meaningful piece of context.
Even so, his instincts kept telling him to do one thing.
To thrust his hips into this girl.
Fill her womb with his sticky semen and impregnate her.
The former was so that he could gain pleasure from the act.
Meanwhile the latter was to satisfy his primal reproductive instincts.
This instinct was the one who commanded the series of movements that his body made.
"Ah…haa…ang….eung…! Ahh..aht!"
-Rip!
His hand tore Yebin's dress apart.
Since it was originally a thin dress, it didn't take much effort for Siwoo to rip it.
As Yebin leaked out a shriek, her alluring body became visible through her disheveled and torn clothes.
Her breasts bounced everytime Siwoo moved.
Still, for such a petite and short girl like her, the volume of her breasts was beyond comprehension.
Swollen blue veins and the ripples on her chest was a phenomenon one could rarely see in breasts of average size.
Though she was lying down, the center of her chest swayed without sagging to the side. In the middle of each of her tits, there was a perfectly shaped pink area.
Her areolas.
Their size was around the size of a fingertip, which was quite large, but there were no imperfections on its color whatsoever.
They actually contrasted perfectly with her innocent looking face, thus adding to her seductive allure.
"Ah….Hooo…Eut…!"
Siwoo pounded her pussy with a constant rhythm as he fondled one of her breasts.
Then, one of her erect nipples, standing proudly among the exquisite balance of elasticity and softness, captured his gaze.
Compared to her areolas, her nipples had a slightly darker hue.
Beneath it was a banquet of her fair and smooth skin.
Neither too thin nor too voluptuous. Her body was pleasing to the eye, the perfect body for rearing a child.
Unlike a man's body, there was a high proportion of fat that made her abdomen soft and plump.
When Siwoo pressed on it, he felt like his fingers would sink right in. Among this softness, a shimmering green tattoo was engraved there.
To be more precise, it wasn't a tattoo, but her 'Smyrna's Brand.'
Siwoo released the hand kneading her breasts and gently stroked the brand.
It was a brand composed of 19 strokes, almost looking like an abstract painting of the womb.
Entranced by his strength and the pleasure that she felt from his touch, Yebin quickly became a quivering mess as her thighs continued to flinch.
"W-What are you do— Haaaang…! Ah, fuck…he won't understand me anyway…"
Siwoo was clearly caressing her brand, but she couldn't tell it from her angle.
She imagined that he was looking at her tight pussy opening wide to welcome his bulging cock, making her flush in embarrassment.
At this point, she considered escaping from this situation.
As long as she could free her wrists, she would be able to get away from him. But…
"Eunng…! Heung….Haaa…aang."
She hesitated.
Instead of moving on top of him by herself, letting him fucking her gave her new sensations.
Just like how sex and masturbation felt different, and how climaxing in porn and an actual orgasm was different.
To be more precise, she couldn't have imagined that it would feel this embarrassing.
Her taut legs were spread wide open, begging for his dick to fill her up. Her shameful hole was completely exposed to her vision.
Additionally, her breasts kept on shaking, which was only adding to her embarrassment.
She couldn't even bear to look at him in the face.
The fact that her both hands were raised like this made her feel like she was being forced into submission.
It was like she was letting him devour her entire body.
And that sensation made her body feel a degree hotter.
"Ooh…eut…eung…aaaaag…!"
As she lifted her shaking hips, her back formed a beautiful arch.
Her lower lips started spasming, as if it was trying to squeeze Siwoo's semen out of his dick as she joined him in his climax.
"Uahh…aht…heut… Heuk, Ooo…eung…"
Her head was on cloud nine.
She could see stars in her eyes as rough gasps came out of her lungs.
Her body left out of her control completely for around 30 seconds.
"T-That should be enough, right…?"
Yebin quickly turned her head to the side and shut her eyes tightly.
She was still drowning in pleasure, but she began to regain some of her senses.
'What am I doing?'
'I'm already on a tight schedule for his treatment, how could I waste more time enjoying myself with him…?'
As a proper doctor, she knew that she'd have to report his situation to his guardian and that she needed to stop exploring through his body.
"P-Please…pull…it out…!"
However, like a sand castle washed away by the waves, her determination completely disappeared after Siwoo moved his hips again.
The previous climax already made her body sensitive, so when he shoved his cock in again, the sensation only intensified.
His movements became even faster and more accurate than before.
"Euk… W-Wait…! Mr. Siwoo…!"
Siwoo leaned forward and as a result, it pushed Yebin's ass further upwards.
Her waist was almost completely folded and she could witness Siwoo's hard rod going in and out of her own pussy.
Additionally, he drove his shaft in so hard that she felt he was going to impregnate her every time he touched her wombs.
Obviously, that was neither scientifically nor magically correct, but that was how she felt.
"N-No, we really can't—!"
Siwoo didn't listen to any of Yebin's cries.
Instead, he let go of her wrists and grabbed her ass firmly before fucking her more earnestly with his new pose.
Of course, Yebin could escape by now, but she didn't want to.
She shouldn't be doing this, but she wanted to do this.
-Plap! Plap! Plap!
Every time he drove his hips into her, droplets of liquid, Yebin's own cum, splashed all over her face.
"Euk… T-That place…feels so good…"
In the end, Yebin chose to surrender and become his personal onahole.
'Whatever, I don't care anymore! This feels way too good! Why should I resist this?'
That was the thought that came into her head.
"Aht…Ahhh….Heuuuuuh…."
Siwoo's hips movements made her legs sway back and forth.
Then, came the sensation when she felt that she was about to cum again.
"Heuuuuung….!"
She felt each fold of her pussy rippled as his cock became larger.
It was already as hard as a rock, but it hardened like steel.
As if he was about to have an orgasm, it swelled up.
And so…
"Haa…aat… Haaaahh…!"
Yebin's waist trembled from the sensation and at the same time, her cum dripped out in waves as she started writhing in her climax.
Her breasts trembled, her lower mouth was pointed towards the sky, twitching as it received more and more of his semen. Even her backdoor was flinching with every shot of his cum.
"Haa…ngg… Ahh…"
While Yebin was relishing in her climax and trying to extend its aftermath, a sudden change occurred.
"H-Huh…?"
-Whoosh!
From her brand, a tremendous amount of mana started to burst out.
The cause was Siwoo's shaft, which was still inside her.
She felt goosebumps rise all over her skin.
When showcasing large-scale magic, she occasionally felt the mana leaking away from her, but that was only because she had let it happen.
This time however, her mana was being absorbed by someone else in an unprecedented manner.
"P-Please stop…!"
Sensing something amiss, she urgently tried to push Siwoo away.
However, she couldn't move even a single muscle.
Even when she attempted to use magic she ended up failing to cast it due to the fierce surge of mana that was beyond her control.
When she tried to regain control, it felt like she was playing tug-of-war with an elephant, the difference in power was too big.
What more was, the mana that was being absorbed came from her brand, the 'processed' mana she had accumulated for a long time.
With trembling eyes, she looked at his face.
His right eye wore an empty, emotionless gaze.
Meanwhile in his left eye, lies a golden magic reflection, just like what she had seen inside his Ain.
-Crackle!
Black sparks erupted like severed high-tension wires from Siwoo's back.
Yebin's body was trembling, unable to move because of the various impossible phenomena that happened in front of her.
Eventually, Siwoo stopped absorbing her mana.
To be more precise, it stopped after all the ,ama that was saved in her brand was completely drained.
"Huh…?"
Shortly after, it began to discharge in reverse.
This happened through the connection between Yebin and Siwoo's cock.
"Uhhhh…?"
Pure white mana began to flow into her womb, filling up her previously empty brand to the brim.
Needless to say, this process also went against her common sense.
To charge up a witch's mana, they'd need to go over three major steps.
Absorption.
Conversion.
Preservation.
Women couldn't generate mana on her own, so they needed to either draw in mana from their surroundings or borrow it through concentrated mana sources.
This was the absorption process.
Then, they'd convert that mana over time to a form that was the easiest to use.
This was the conversion process.
The converted mana would be stored in their brand, this would make them able to use that mana effectively without leaking anything.
This was the preservation process.
"H-How can this happen…?"
The conversion process usually took a long time.
Even the purest kind of magic would contain impurities, as such, refining it was still a challenging task.
To 19th ranked witches like her, who had a large total mana capacity, it would take a month just to absorb and convert the mana they needed to refill their brand.
However, the mana that flowed out of Siwoo was completely different.
Even after it went through his own body, its purity was especially remarkable.
In fact, it was the first time Yebin ever saw mana with this degree of purity.
If one were to compare this to the highest-grade magic water from the Emerald Tablet, the latter would feel like dirt water.
It felt as if she could use this mana instantly for casting spells even if she hadn't converted it first.
Not to mention the high quantity of the mana she received.
Yebin thought that he was just giving back what he had taken, but what he gave out was way more than that.
But, the more perplexing thing was that she could feel an immense amount of mana remaining in his body.
To put it in simple calculation, Yebin gave him ten units of mana and he gave her twenty in return, but there were still thirty units inside his body.
That meant, Siwoo didn't simply refine and return her mana.
He absorbed it, amplified it then purified it before returning it back to her.
Considering that normally, the purity of the mana usually decreased significantly after amplification, it was hard to comprehend how Siwoo could have done this.
"W-What on earth is this…?"
As Yebin stared wide-eyed in astonishment, Siwoo suddenly twisted his head like a patient with a neck spasm.
Trembling, his body fell backwards onto the bed.
"What's happening?"
The aftermath of the sex was suddenly interrupted by the presence of magic and resolved by Amelia, who rushed out of her lab because she was startled by the magical aura.
