The Yin Crest
As Miel carved more than half of the Yin Crest onto Seona's lower abdomen with her fingernail, she could feel the change that had overtaken her own body as well.
The moans spilling from Seona's mouth growing wetter by the second, and the cock hanging beneath his belly rising even more rigidly erect, were no coincidence.
She herself was feeling the pleasure Seona experienced, spreading through her entire body by way of the Yin Crest. Seona, too, would be receiving in full the pleasure radiating from her own thoroughly heated flesh. Miel's sex was already drooling as much as it could.
The pleasure she took from Seona was transmitted to Miel, and that pleasure was then amplified and sent back to Seona. In that endless circulation of rising pleasure with no ceiling in sight, Miel's mind reeled. They could feel each other's ecstasy, and it only grew fiercer.
What would happen once she finished carving the entire Yin Crest?
The mating between a male branded with the Yin Crest and a succubus, once begun, delivered pleasure enough to drive both of them mad—because they shared and amplified endless pleasure with each other.
Watching the two of them, Yurin felt that something was wrong. It felt as if the Seona she knew was about to become something else entirely.
Now even Miel seemed unable to hold back, letting sweet, coquettish sounds spill from her lips.
"Heheh... heuh... heuh..."
Looking at the man and woman moaning together, Yurin told herself this had to be a nightmare—that she needed to wake up soon and go see Seona. She firmly believed that the Seona she adored would never let anyone else hear a voice like that.
Unable to endure this reality any longer, Yurin hung her head and squeezed her eyes shut, clinging only to the happy memories she had shared with him.
And at last, the Yin Crest was fully carved onto Seona's lower abdomen.
Miel was already gazing at him with her tongue slightly protruding and her face flushed red. Seona, too, was breathing hard, his eyes unfocused and wavering. They looked as if they had already finished making love.
It was fortunate Yurin had her eyes tightly shut beforehand; if she had seen this, she might have completely lost her mind.
Miel took Seona's erect cock into her mouth and began sucking with wet, slurping sounds. Seona felt as if he had just finished ejaculating. Unable to endure the pleasure she was giving him, he began to moan loudly.
Just because Yurin had her eyes shut did not mean she could block her ears. Her arms, bound by handcuffs and unable to reach her own face, only filled her with resentment. She did not want to see that sight any longer.
Even though she had watched him being raped by other monsters, seeing him have sex with that succubus made her feel her mind would not remain intact. Because that was not rape. It was because it sounded like the sex of lovers...
Seona was swept away by continuous waves of pleasure. His entire body would not move under the ecstasy climbing without end.
When he had been violated by Yurin, when he had been violated by Minji, when he had been violated in turn by the other monsters—at first it had given him pleasure, but in the end it had only brought him pain.
But what he felt now was different. He began to grow afraid of the sensation of pure pleasure piling up throughout his body.
Then something warm and wet swallowed the thing between his legs. It was similar to the pleasure he had felt from Yurin, yet even better than that. With eyes that could not properly focus, he looked down at it.
It was the succubus Miel.
That monster who had suddenly started acting differently a few days ago had done something to him today.
What was it again?
He kept trying to remember what it had been, but the pleasure from his lower body cut the thought short. No matter how many times he tried to grasp that important thing, his head would not work properly under the pleasure, so he gave up thinking any further. And he began to surrender his body to it.
He started floundering in the waves of pleasure that climbed higher and higher, until suddenly he felt a climax as if his mind were exploding.
When Miel felt Seona's cock throbbing as he was about to cum, she pushed it deep into her mouth to swallow everything.
"Bwurururut... pyuuuut...."
He began to ejaculate with tremendous force. His cock trembled madly enough to make sounds as it painted every corner of Miel's mouth white. She tried to swallow it all, but in the end the sheer volume made semen drip out between her lips. The area beneath Seona grew soaked.
Miel's lower body, as she sucked him, also shot out clear love juices like a water gun, spraying madly to dirty the floor. At the moment of ejaculation, the pleasure of Seona's orgasm had circulated through her body as well.
"Haa... haa..."
Even though it was Seona who had cum, Miel wore an exhausted expression too. As if her stamina to move any further had bottomed out, she draped her body over him, and just like that the two fell asleep. It looked as if a lover had collapsed atop her partner's belly to rest.
Even though Yurin was hearing those sounds with her ears, through continuous delusion she escaped that reality and claimed Seona in her own thoughts alone.
How much time had passed? The semen and love juices that had soaked the floor were nearly dry. And Seona and Miel slowly rose.
The pleasure Seona had felt the night before rose vividly in his mind. Who had bestowed that pleasure. He realized it the moment he opened his eyes.
It was the one who had treated him like an object, who had let other monsters violate him, but who now showed signs of cherishing him—the succubus Miel.
Confusion flooded Seona's mind. He was disappointed in himself for having engaged in lover-like sexual acts with Miel right in front of Yurin. He thought he must not give his body to Miel any longer. If he surrendered himself to that sweet pleasure like this, he felt he would no longer be Yurin's.
But deep in his heart, he wanted that kind of pleasure. Unlike the sex that had only tormented him with pain until now, this was the first sex that bestowed only pleasure upon him.
So confused that he pushed Miel, who had been lying atop him, off to the side. It was an action Seona would not normally have taken, but the turmoil he had just endured led him to it.
As Miel's body slid from Seona's belly to the floor, she woke. She, too, had found the sex with Seona so pleasant that she was replaying the pleasure she had felt until she fell asleep. Though she had been pushed by him and now lay face-down on the floor, she smiled bashfully and spoke to Seona.
"Did it feel good?"
"...."
Normally Seona would have answered out of fear, but suddenly Miel no longer looked frightening. She felt almost like a lover.
No. He had always been afraid of his lover Yurin as well, so that could not be it.
At the end of that thought, Seona arrived at one absurd conclusion. It felt as if he and Miel had become something more than lovers. More than lovers meant a married couple who would spend their lives together. It was absurd. The one he had decided to marry was Yurin, bound to the wall over there.
Thinking that, he looked at Yurin, who hung her head against the wall. As if she had lost her mind, she muttered and occasionally laughed with a "Hihihik."
As he watched her for a long while out of worry, he felt something touch his face. Miel's warm, soft palm and fingers had taken hold of his cheek and chin. And she turned the head that had been looking at Yurin toward herself. It was not done with forceful coercion; Seona had come to look at Miel of his own accord. He could not help but turn to her because of the warm heat of the hand gently holding his face.
And Miel spoke.
"Look at your lower belly. It's the same as the pattern carved on mine, right? That's called a Yin Crest. When a succubus decides on a partner for life just once, she carves a shape identical to the Yin Crest that appears on her own belly onto her partner."
Listening carefully to Miel's words, Seona understood what she was trying to say. As he heard the words that would continue, he gulped.
"In other words, you're mine now."
Yurin, who had been acting as if she had lost her mind, stopped moving. She had tried to escape reality, but she heard a statement she could not ignore.
The bitch who had kidnapped them when they were happy after holding their wedding, who had then gang-raped Seona indiscriminately by other monsters like passing around an object, had now stolen even her man. She even called him her partner.
She resented the gag that blocked the curses that would pour from her mouth. She wanted to kill them all—Seona who had given his body to that rotten bitch, that succubus, the monsters who had violated him, Minji, every single bitch who had ever looked at Seona until now. She hated Seona, who was looking at the succubus as if her own actions were not even visible.
The man and woman who had been staring at each other for a long while. The woman whispered something small into the man's ear, then took Seona's hand and pulled him to his feet. And then she went outside—a place she had never taken him before.
Leaving Yurin behind, who was clutching her miserable feelings.
