Write the third erotic chapter of a detailed story with a lot of dialogues, based on this: (Trace and Mukuro remove their clothing. Then they both stimulate each other's body. Then they lay together on the bed, holding each other tightly as Trace starts to position himself over Mukuro. Slowly, Trace puts his 21 cm human penis inside Mukuro's pussy, and start to slowly penetrate her, losing himself in pleasure, as he feels his rod slapping against her meat)

The story so far is this: [Chapter 1: The Meeting
A hushed silence filled the regal room as Trace Legacy, the human Grand Templar and Duke of Edinmire, and Mukuro, the Demon King, faced each other across the wide wooden table. Both leaders glanced at their advisors and assistants, who stood behind them, holding their breath in anticipation.
“It’s been a long time since we’ve seen each other face to face, Mukuro,” Trace remarked, his voice neutral yet assertive.
Mukuro’s damaged eye flashed with cold amusement. “Indeed, Trace Legacy. I must admit, I was intrigued when you proposed this meeting.”
There was no denying the power and influence wielded by the two leaders. Trace, backed by the formidable Templar Order, was in control of significant human territories, while Mukuro possessed a substantial demon following and was known for her ruthlessness and brutal efficiency. However, even within their already divided worlds, open conversations between these figures were rare.
“Let’s not waste any more time on pleasantries,” said Trace, feeling the unease in the room. “We’ve both had reports of the instability within our realms, as well as in each other’s territories.”
“I’m not blind to what’s happening, human,” replied Mukuro, her voice icy. “The question is, what do you suggest we do about it?”
Trace took a deep breath and glanced at his advisors, seeking their silent reassurance. “I propose an alliance between our realms, forged through marriage.”
The tension in the room escalated at an alarming rate. Mukuro stared at Trace, her blue eye ablaze with incredulity and a hint of amusement. Her advisors muttered among themselves, exchanging wide-eyed glances of concern.
“An alliance forged by marriage?” Mukuro repeated slowly, trying to weigh the legitimacy of the proposition.
Trace nodded, gripping the edge of the table tightly. “I believe it would be the most secure and mutually beneficial way of ensuring the safety and prosperity of our respective realms.”
Mukuro leaned back in her seat, considering the offer. “And who, human, do you suggest for this marriage? You? Or perhaps another from your ranks?”
Trace sighed, feeling the weight of the proposal. “If it will forge a stronger alliance, then I am willing to honor the agreement through marriage myself.”
The two leaders locked eyes, trying to gauge each other’s sincerity.
“Your offer intrigues me, Trace Legacy,” Mukuro finally conceded. “But perhaps we should discuss the finer points of this arrangement before coming to a decision.”
For the first time since the meeting began, both leaders allowed a small, genuine smile to grace their lips. The air was still thick with tension and apprehension, but it seemed that for the moment, their collective determination might just override the potential for provocation.
As the conversation began to explore the details and implications of this alliance, both Trace and Mukuro knew that the decisions made in this room could change the course of history for both humans and demons.

Chapter 2: The Test
Trace and Mukuro discussed the finer points of their proposed alliance until all the advisors and assistants had dispersed, leaving only the two leaders in the dimly lit room.
Mukuro dragged her finger along the wooden table, pondering the agreement that had been hashed out between them. “You seem quite eager to marry me, Trace Legacy. Are you perhaps attracted to this half-demon body?” she teased, her blue eye flicking up to meet his.
Trace’s face reddened, and he avoided her gaze. “This is purely for the benefit of our realms,” he replied, maintaining his composure despite the provocative comment. “You know as well as I do that we need to unite to ensure the safety of our people.”
Mukuro smirked, her voice dark and silky. “Do not try to deceive me, human. I can see the deviance hidden beneath your politeness, especially given the knowledge, I have about your past personal problems.” She leaned in closer, her breath hot on his cheek. “But I will give you a chance to prove your worth in a true test of your dedication to our alliance and your commitment to our future.”
Trace’s heart began to hammer against his chest as Mukuro’s intentions became clear. She was offering him a test of his commitment to their alliance through a demonic tradition – a sexual encounter. The notion of entwining his body with this powerful, ancient demon both terrified and intrigued him. He knew that if he backed out, she could easily dismiss his proposal, labeling him as a coward and undermining his authority.
Trace took a deep breath, warring with his doubts and fears. Finally, he met Mukuro’s icy gaze, determination shining in hisl light blue eyes. “Very well, if that is what it takes to prove my dedication to this alliance, I accept your challenge.”
Mukuro’s expression remained unreadable, but her eyes flashed with amusement and surprise as she rose, leading Trace to the chamber where the test would take place. As the door closed behind them, they began to disrobe, their bodies bared to each other as they prepared for the intimate dance that would determine their future.]

Trace Legacy's description: [HOMELAND: Eversummer, Human Territory
CURRENT AGE: 24
BORN: 457-458
SPECIES: Human
HEIGHT: 5'9" (175 cm)
MASS: 160 lbs (73 kg)
CLASS: Grand Templar, Duke of Edinmire
AFFILIATION(S): Templar Order
Trace Legacy (IPA(key) /treɪs ˈlɛgəsi/) is a male human and the main protagonist of the webcomic Twokinds. He is the leader of the Templar Order.

Appearance
Trace is a pretty average Human in terms of height and build. He has bright light blue eyes and hair, the latter of which he keeps long and messy. He has a triangle tattoo on the left side of his face, also light blue in colour.

Biography
Trace was born into a poor farming family in the village of Eversummer, but was taken in by the Templar at a fairly young age where he quickly developed his magical talents. Whether they where friends prior to Templar training or not is unknown, either way Trace was friends with Red, a fellow student at the Templar Academy. Unlike Trace however, Red showed very little magical potential, which led him to eventually leave the Academy. Trace also meet his future wife Saria while in training too, after a few failed attempts to gain her attention using less practical ways, he managed to work up the nerve to talk to her. They dated for a while and eventually were happily married despite differing personalities. One day, while visiting their house near the borders of the forest, Trace and Saria were attacked by a random Keidran attempting to rob them. Trace managed to deflect one arrow meant for him, but another grazed Saria. Unknown to Trace, the arrow was coated with poison and as the Templar left to chase the thief, she died.
Heartbroken, he tried to use black mana and forbidden magic to resurrect her. It backfired, almost destroying Trace's mind in the process. This incident caused a huge personality change for Trace, he became ruthless and tyrannical as a result of all the suffering he had gone through.
Bent on revenge, he overthrew the old Grand Templar, took her position, and replaced the Master Templars with his own inner group. Afterward, he started a genocidal campaign against the Keidran, transforming the previous peace-keeping force into a military institution to rival the Human's own army. He also started the construction of large mana towers to fulfill some unknown, yet apparently lethal purpose.
While this was happening he found comfort in a relationship with a female bartender called Maren Taverndatter, although he originally did not formed that relationship for love: unbeknownst to everyone he had in mind to use her body as a vessel, that the dark entity Detritus (created by Trace himself) could use to bring Saria's soul back, replacing that of his beloved Saria, but he scrapped the plan for unknown reasons.

Personality
-Trace's personality when he was very young is unknown and his personality is only explained after he had joined the Templar. Lady Nora gives an account that during his younger years in the Templar Order, Trace was rather shy, but also had a bit of a temper.
-After spending a few years with the group and rising to higher positions Trace became more confident, before this he had been discontent with his position, likely due to his natural ability far surpassing that of even more experienced mages. Trace apparently had a slight prejudice against Keidran like many Humans seem to have, though he wasn't outright cruel. Roselyn's flashback recounts that while Trace and Red were still at the Templar Academy together Trace also seemed rather disinterested in such considerations, preferring to study unlike his brash friend.
-When Trace married Saria au Gruhen he seemed to be very content and overjoyed, especially hearing that he was going to be a father soon. As mentioned growing up Trace only had typical Human prejudices towards Keidran.
-However, after the death of both his wife and unborn child at the hands of a Wolf Keidran he grew to completely despise them. After suffering that tragic loss Trace became heartless and bitter, a true tyrant, forcibly taking control or the Templar Order and attempting a mass genocide of Keidran in an act of revenge.

Abilities and Powers
Swordsmanship
Although Trace is much more proficient with magic, he is supposedly also very capable in this regard.

Trivia
Trace's triangular marking on his cheek is never explained. It may be some kind of magical marking or tattoo as the only other person in the series to have it is Sealeen, another mage albeit a Mercenary.]

Mukuro's description: [RACE: Demon
AGE: 1000+
HEIGHT: 5'2
OCCUPATION: King (despite her being a she)
Mukuro (軀, Mukuro?) is a powerful female demon who lives in Demon World and is part of a triumvirate of Upper S Class demons known as the The Three Kings, who rules over Demon World in the Yu Yu Hakusho series.

Appearance
Mukuro normally conceals her face behind bandages that are studded with paper tag wards (御札 [おふだ], ofuda, translated as Honorable Holy Writing) and around her whole head. Only her damaged right eye is visible through an opening in the bandages and her voice is electronically distorted (and lowered) so as make her sound more like a man to those around her; a charade further reinforced by the fact she uses the supreme-masculine pronoun of "ore" rather than the gender-neutral/feminine pronoun of "watashi" when referring to herself in the Japanese language version.
She also keeps her hands bound and shackled in chains, although it appears the chains have been broken by the time she appears in the series (though not the shackles themselves). She wears loose pale-blue/white pants and black martial arts slippers, a white long-sleeved shirt with a purple vest with gold trim over it, and a long red sash tied around her waist.
However, when she removes the bandages from her face, she has messy orange hair parted to the left with a bandage wrapped around her head (like a headband) and cloth hanging down over much of the right side of her face. Her eye color is blue. Her right eye is in fact covered by a cybernetic lens, although she can see with it perfectly fine without the lens. Furthermore, the entire right side of her body is covered in scar tissue and burn marks: a result of the damage done to her when acid was poured on her. The damage was so extensive that most of her right arm and her right leg have been replaced with mechanical limbs, although the hand (from above the wrist) and foot (from above her ankle) still look natural.

Personality
When Mukuro first appeared, she came off as having a very mysterious personality. During her years as a warrior, few knew that Mukuro was female. It is however, interesting to note that the specific reasoning why she decided to pass herself off as the opposite gender is subject to speculation. In a shocking turnaround, she made a point of removing her bandages at the start of the Demon World Tournament.
Raizen describes Mukuro as a traditionalist and an isolationist and notes that she likes Makai just the way it is and believes it should remain in its pristine, untouched and chaos-ridden state. This said, provided that everyone minds their own business and affairs in their own respective worlds, she will leave both Human and Spirit Worlds as they are as Mukuro focuses her attention solely on Demon World, making Mukuro the lesser of two evils between herself and Yomi, such that should there come a time when Yusuke must extend an alliance to either, Raizen in his final moments advised him to choose the former. While Raizen was slowly starving to death, even stubbornly setting himself as a staunch and primary example for abstaining from human consumption, and Yomi insisting that there is no reason for demons not to hedonistically eat as many humans as they see fit, Mukuro maintained a pragmatic outlook, remarking that the consumption of humans should be limited but not forbidden.
She has been seen engaging in casual conversation with Hiei, and tosses occasional sardonic quips toward him, suggesting she has some sense of humor. In a telling moment, she fully exposed her damaged body to a semi-conscious Hiei and revealed to him her painful past. It is likely that Mukuro gravitated towards Hiei because she saw similarities between herself and him.
In combat, however, Mukuro is completely ruthless. She describes herself as one of the most ruthless, well-known killers that Makai has ever seen. At the same time, Mukuro seems to hate herself as well, punishing herself by wearing chains - largely to represent the emotional damage that holds her in bondage, imprisoned by her own dark past.

History
Mukuro was abandoned on a freezing, snowy night. She was found by a wealthy humanoid demon, who became her "father". He would go on to abuse and rape her at his own leisure. He placed a micro chip in her to show the 'goodness' in him - so that when she ever thought about killing him, the chip would activate and show how good he was to her. In a particular macabre and sadistic twist, he would go on to rape her on her birthdays as a present. As a result, Mukuro came to view everything about her childhood with disgust at both Chikou and herself.
Eventually, at the age of seven, Mukuro poured acid over her head in order to avoid his desire, only leaving her left side unharmed. He tossed her out, which she describes as 'rebirth'. She then replaced her damaged limbs with robotic parts. She swore to seek power at all costs and gained a reputation for violence, covering her face with bandages and leading many to believe that she was a man.

Three Kings Saga
With Yusuke joining Raizen, and Kurama joining Yomi, Mukuro sends a video message (a spirit of words) to Hiei, asking him to come see her. Mukuro asks Hiei to show his true strength by fighting the man that gave him the Jagan eye. The battle ends with both in pieces, and Mukuro revealing that she had Hiei's Hiruseki stone. Then Mukuro places them into regeneration tanks. She puts Hiei's tank into its own room before telling him her life story while removing her clothing to show him her true form.

Powers and Abilities
Mukuro's power depends entirely on her state of mind. In the anime, it seems that her power is directly proportional to how much hatred she feels. As stated by Kirin, Mukuro utilized at most, half of her maximum strength in the Demon World Tournament. Thus, Mukuro at her peak was at least the second most powerful character in the series, with Raizen being the only one capable of being stronger than her.
Mukuro's ruthlessness as a ruler and merciless brutality in battle strike fear in the minds of countless apparitions across the plains of Makai. Her hard-earned reputation alone devastates the composure of her opponents. Many powerful S-Class Demons would rather shamelessly admit defeat than face her in combat. Only when facing Hiei does she hold back and hesitate to go for the win. The similarities of their respective life experiences create a connection between the two, as can be clearly seen in their anime-exclusive battle. This appears to be the source of her hesitation; she finds herself feeling emotions everyone had thought her incapable of feeling given her dark past.
Although Mukuro is primarily a hand-to-hand combatant, she appears in a brief flashback to be using a sword during her time as an assassin, although she is almost never seen carrying one around.

Known Techniques/Moves
Superior S Class Energy: Being a very experienced Upper S Class, her power is only challenged by few Demons. She defeated Hiei, who was an Upper S Class Demon during their battle, despite her using only barely more than half of her full power against him. She also barely defeated Natsume, despite being at a disadvantage due to losing a great part of her rage and hatred, which is the source of her power.
Telepathy: Mukuro appears to hold the power of telepathy, as seen when she accepted Yusuke Urameshi's proposal of a tournament to decide who would rule Demon World, and seemingly sent this thought to Yomi. However, this may also be attributed to Yomi's supposed ability to hear whatever is said within his territory. It is also mentioned by Koenma that, during her battle with Hiei, the two of them were "butting their thoughts against another " as opposed to exchanging any dialogue. This seems to be true, at least in the Japanese subbed version, as they are most definitely communicating, though neither speaks aloud. In the manga, Hiei remarks that "you showed me those memories", referring to Mukuro's past. His choice of "showed" rather than "told about" infers some sort of telepathy between them.
Third Dimensional Cutter (空間切り手, Kūkan Kirite, literally "Space-Cutting Hand"): In the anime, she demonstrates the ability to cut through the entirety of the third dimension. Whatever it comes into contact with will be cut as well. Her control over the location and shape of the cuts makes her utilization of the dimensional distortion considerably more effective than Kuwabara's Jigen-Tou. This is unofficially named in the original Japanese version by Kurama.
Dimensional Forcefield: Enough of these cuts can create an impromptu, and deadly, forcefield that causes severe harm to anything that comes in contact with it. Kurama likened this barrier of Mukuro's to a razor-sharp spider's web.
Energy Punches: She has been seen being able to cause geyser-explosions of energy whenever she punches.
Energy Fist Blast: She can surround her hand in energy and then release it all at once, damaging whatever is in its range. She does this to Hiei in the manga as well, when he coldly insults her affection for him during the Demon World Tournament in the anime and again about her reaction concerning Chikou in the manga, and punches a large hole in his abdomen that blasts him out of her room and fortress-home. It is called "Piercing Beam" in the YuYu Hakusho card game.
Flight: This is a special ability where the user manipulates their Energy so that they can levitate or fly.
Telekinesis: it is highly likely Mukuro possesses telekinetic powers. During her battle with Hiei, Mukuro destroys various large rock formations with her energy, creating several large, sharp stakes of rock. She then uses telekinesis to throw these at Hiei over a significant distance at high speed; however, Hiei is able to destroy them with his sword before damage is dealt. Mukuro's reddish energy can be seen surrounding the rocks, guiding them accurately to their target.

Etymology
The name Mukuro means "body, corpse, tree with rotten core" (軀).

Trivia
In Chapter 161 of the manga, Mukuro is stated to have a Youki of 1,575,000. This would mean she is the most powerful out of all the Three Kings at the time.
Mukuro fought with significantly less power than she was capable of in the Makai Tournament. Her fight with Hiei lessened her anger, and from then on, she was much weaker. This occurred in round three (round two in the anime). In chapter 172 of the manga, one of her underlings goes on to state he was amazed she was able to use more than half of her maximum power, considering the friendly nature of the competition, observing that Mukuro's power varies according to her moods, achieving their highest level when she is at her maddest.
Despite having their abilities shown in the anime, neither Mukuro, Yomi, or Raizen have shown any of their true skills in the manga.]
