He pushed her hidden flesh inwards and the tip of his penis hit her cervix. He used a massaging rotating to embed the head in that donut-shaped flesh lid.
"~~ Kh…"
After he had so thoroughly rubbed at her G spot, the sensation of having her womb lifted up proved too much.
Pleasure welled up from deep inside her body, reached the surface, made a sudden reversal, and seemed to sink into the core of her spine.
"Ahhhhhhh♡"
Her spine arched backwards on its own and she cried out in an octave not often heard from her. Her nectar-covered flesh had already contracted deep inside and wrapped around every contour of his shape.
An intense jerk ran through both their bodies as they locked lips on the bed.
"Kh!"
"Ahh…ahnnnnn…"
They exchanged sexual cries as if breathing them into each other's mouth.
Thick magma sprayed out into her inner garden that contained her egg cells.
"Hh! Hh!"
Intense heat burst inside her belly. The surge from directly below was so incredible that her entire body writhed without even letting her scream.
Energy seemed to push up within her body and the butt contained in the navy blue fabric bounced up and down. The anal flesh at the center also seemed to have gone mad. A clear fluid sprayed from the gap in that swelling hole.
"Kh…ahh…"
Machina's expressionlessness vanished and her face melted even more erotically than a normal girl as she lost herself in orgasm.
Pleased, Mutsuki felt his mouth loosen a little.
He still knew nothing about her, but that expression was more than enough for the time being.
He was the only one that could make her look like that.
The chime rang.
The next period was starting and someone would likely arrive at the infirmary soon. They needed to head back.
"What about the sperm?"
"…We can do that next time."
They were used to it now, so they kissed once more to signal the end of this time as lovers.
"Mutsukiiiii!"
Ange ran in just as Machina had changed into her uniform. Mutsuki had fixed his clothing and the bed, so they could hide what they had done.
"Ibekusa Machinaaaaa! Attacking while I was drowning is a cheap trick!"
As soon as Ange saw the situation inside the room, she made her own assumptions about why a FeTUS member was alone with the Serpent's Eye holder and she moved to stand in front Mutsuki. She had not wanted to turn her back (or rather, her butt) toward him that morning, but she faithfully fulfilled her duties as bodyguard.
She pulled out the silver wings pendant she wore.
It started burning blue and immediately transformed into a sword far too large for a girl her size. It was Prominence, Ange's divine sword.
"Surely you know capturing or attempting to capture a powered individual is in violation of the Deadly Sins of those who live on this earth!"
"Positive."
The two girls glared at each other in an explosive situation.
Ange seemed to think Machina was trying to abduct Mutsuki. He was shocked by how rapidly she had flared up and he frantically tried to stop her, but…
"W-wait, Ange. You've got it all wrong. Ibekusa-san was…"
"…It's fine."
Machina cut in before Ange could argue back.
She chose to stand in a more open position.
"This is the quickest way for the two of us to settle this matter."
"I have deductively concluded that combat is unavoidable in the current situation. Beginning decompression of anti-angel tool. Expanding as a geometric medium in accordance with Poincaré."
A glowing circle appeared on the floor around Machina.
It looked like a magic circle, it contained connected lines and geometric figures, and it ultimately formed runes.
FeTUS Witches Miss E was demonstrating her willingness to fight, so Ange lowered her hips in preparation.
"I won't kill you, but I will hurt you as much as I can!"
Silent and chilly killer intent clashed between them, proving that was no mere threat.
She had monitored the other for ten days in case she did something, but now that Machina was targeting Mutsuki (or so Ange thought), she knew exactly what to do as a guardian angel.
"I don't care if you're some high level FeTUS member! How much can a mere human do without a Springloaded!?"
Ange charged in to take the first strike.
"Haaaaaaaaaaaaaaaaaaahhhhhhhhhhhhh!"
She instantly filled the gap and swung her large sword.
No normal person could have reacted to her speed, but Miss E did one quick thing in response: she tapped her toes on the circle drawn on the floor.
"The Springloaded…"
In that instant…
"…!?"
"…are nothing more than tools given the power to move. That is, that have been 'loaded with a spring'."
Ange's charge was forcibly stopped.
The concrete floor suddenly swelled up as if creating a wall to protect the circle's master.
"So if we give them the power to move, any tool can become a Springloaded."
"Gh!"
Ange could easily slice apart the twenty centimeter thick concrete wall, but she still had to stop her charge.
And in the instant she killed her momentum, the bisected wall lowered back into the floor.
This time, it became a stepping stone for its master.
"—————!"
A slender arm gently touched the border between Ange's shoulder and arm.
That was all it took to seal the movements of the most powerful guardian angel. Her divine sword's size meant centrifugal force was necessary to wield it, so she could not swing it with that point restrained.
Even with power that exceeded human knowledge, she could not escape the laws of physics while in this world.
"Corona!!"
Even so, the angel continued her attack. Blue flames burst from her back to form wings and assaulted Machina from point-blank range.
However…
"…"
"Heat radiating fibers!?"
At some point, the golden circle had moved from the floor to the air to protect the Witch.
The glowing runes distorted the path of the blue flames, diverting them in a harmless direction. Plus, the angel was unguarded with her focus turned toward her own back.
"Khah!"
One leg was taken out with a heel and she was brought to the ground much like a judo throw.
The throw was powerful enough to crack the rubber tiles of the floor and the smash the concrete beneath. Even Ange was left feeling dizzy.
Mutsuki had known how powerful his angel bodyguard was, so he had been worried that Machina would be injured and was left dumbfounded by this complete reversal of his expectations.
Meanwhile…
"Tools only demonstrate their true ability when utilized by those with intelligence. That is…"
Machina brought her fingers to the partition next to the bed. The magic circle moved there and audibly transformed the metal pipes and curtain.
"The Springloaded only demonstrate their true power when used by the humans who hold the Fruit of Knowledge."
A total of three pipes came to life – the two that had acted as legs and the one to support the curtain. The two fused together in an Lshape and the final one gained a long, narrow point on the end.
After the curtain rolled up and connected to both ends of the curving pipes, the final one was nocked as an arrow.
"You should not assume that those who use a tool are weaker than the tool."
"Gh…"
When Ange finally recovered from her rattled brain, Machina was pointing the tip of her giant bow and arrow at the angel's throat.
The battle was over. Mutsuki had not even had time to rush in and stop them. In only about five seconds, the most powerful guardian angel had been soundly beaten.
"As I assume you can now see, FeTUS has an extreme advantage against angels in combat."
The girl saw the defeat on the angel's face and pulled back her weapon without finishing her off.
She summoned the golden magic circle again and returned the broken floor and partition to normal. She brought the bent metal and torn fabric back together and they returned to normal as if by magic.
Mutsuki had seen the powers of an angel like Ange and a demon like Lucia, but he was amazed that a fellow human could do something like that. Ange's mind seemed to have gone similarly blank after her overwhelming loss.
"And now I will tell you what I initially wished to discuss here."
Machina faced them after returning everything to normal.
"There is currently some unrest within FeTUS's command structure, so Fujita-kun is being targeted by one of the FeTUS Witches."
"————"
"She is Miss C…aka Black Cat. She is more powerful than me."
Her plain voice was no different from normal. Her tone was neither heated nor icy.
But Mutsuki could no longer think it sounded like a machine.
"She is extremely dangerous. She will use any means necessary, she does not care about any secondary damage she might cause, and she enjoys combat. She will likely attempt to kill her target's bodyguard…which means you, Jiyuuni Ange. You cannot fight her off, so I recommend you flee."
"Flee!? Like hell I'll do that! I would never-…"
"…"
"…"
Ange snapped back, but she could say nothing in response to Machina's silent look. She was not stupid enough to deny she had just suffered a definitive loss.
"If you hear the sound of a bell, escape immediately."
That was all Machina had to say, so she turned her back.
"Wh-why did…you tell us that?"
The boy's trembling voice pursued her as she began to leave the room.
She looked back from the doorway and glanced at Ange.
"We cannot get along. FeTUS is incompatible with angels and demons. But as a personal opinion, I feel no reason to take a hostile stance against you."
She then looked directly at Mutsuki.
"I am not your enemy."
Then she left.
Left behind, Mutsuki was confident of something from the expressionless expression he had seen on her face.
She could do it.
She could get along with the others.
However…
"That…damn human…!"
Ange returned her beloved sword to its pendant form and her voice trembled in humiliation.
It looked like it was still going to take some time on this end.
