A/N: Long time no post.

Not much to say here, but again, thanks to my trash girlfriend for having betaread the chapter. And thanks to you guys for the reviews! At this point, the amazing support I receive is mainly what makes me want to keep going, so I'll never be thankful enough.


Unfated Passion

There was no doubt about it anymore; what Miku felt for the Queen of Demons was stronger than a trouble-free attraction. Every touch, every sensual caress that Luka gave her had been enough to make her heart beat faster than she ever thought imaginable. The delightful, seemingly everlasting night she had just spent with her had sufficiently proved it. All the incredible sensations Miku had felt in the past few hours had made her want for so much more. She had kept asking the succubus to continue touching her after every orgasm she had given her, almost pleading with her a few times, which doubtlessly had pleased the demon, making her smile conceitedly.

It was actually frightening how much the human was getting addicted to this pleasure that made every one of her limbs shiver at the slightest stroke. Luka had so much power over her. When they were having sex, she was completely wrapped around her little finger. Miku was confident that she would do anything the succubus asked her to do. But even so, Luka never tried to play with her mind even if she easily could when Miku was so vulnerable to her. Instead, she was very gentle, touching her only where it felt right, never once teasing her, and what the princess liked the most were the tender, almost affectionate, caresses the succubus occasionally gave her during their passionate time.

However, now that they were done, Miku felt an undeniable emptiness overwhelm her. It was like she still ached for the other female's touch even though she was exhausted from the countless orgasms she had. She only wished to have all of her attention, but it was hard to obtain when they weren't having sex.

Luka was currently lying down next to her, not speaking a word; almost cold, even after the fantastic night they had just shared. She only stared at the ceiling with an emotionless expression; she seemed lost in her thoughts, but the teal-haired girl couldn't exactly tell what was going on. Luka was always so hard to read, but she supposed that it was one of the reasons why the succubus made her so curious and interested.

Still, Miku was a bit hurt. She was now very aware that she had gotten too emotionally involved. She would have been fine with only a mutual sexual attraction, but it was more than that on her end. What pained her the most was the fact that those feelings weren't reciprocated. She tried to kiss Luka while they were having sex, only for the succubus to reject it by turning her head. They had already kissed before, so she didn't understand why it seemed to bother her this time.

Eventually, the pink-haired beauty sat up, lazily stretching her arms. The undying hunger in her eyes seemed to have disappeared. She looked oddly satisfied for once. However, after a careful examination, she noticed that faint lust was still noticeable on her face. Perhaps she wasn't one-hundred percent pleased after all?

Miku then indiscreetly looked between the other female's thighs, intense curiosity flashing in her eyes. Luka had been sexually excited the whole time they had been doing it, the wetness of her most intimate area palpable. Despite how aroused she appeared to be, she never showed any willingness to be touched by Miku. The succubus was the only one who was in control and she never once tried to gain pleasure for herself. The princess found that to be a bit…frustrating. When Miku tried to place her hands on the succubus, Luka forced her to lie on her stomach, making her unable to touch her. Miku wondered why she didn't want to be pleasured. In fact, she had thought that sex demons were more obsessed about receiving than giving.

Miku knew she would regret it if she didn't ask. She looked away and crossed her arms over her chest, feigning indifference even though she was very curious. Her fantasies about touching Luka were getting wilder. She was almost obsessed with provoking different reactions from her.

"Will you allow me to touch you too? I… I mean, it is only fair that I also…" The princess bit her lip, unable to finish her sentence as a sudden nervousness overwhelmed her determination and interest.

Luka didn't even move a finger. It was as if she wasn't surprised by the fact that Miku had dared to ask her to return the favour. After a few seconds passed, she shook her head, an amused smile playing on the corner of her mouth.

"Do you truly believe you would be able to satisfy me? You never had sex before this. You never once pleasured a female. Even if you tried, you would not be able to make me orgasm or give me even a bit of pleasure, for that matter," The succubus stated confidently. "Besides, letting myself be tamed by a human is out of the question."

The princess growled, anger boiling up inside her. Oh, how she hated the way Luka talked right now. She didn't have any problems with touching a human, but the idea of one touching her almost seemed to disgust her; it didn't make any sense! Yet, she couldn't help but feel hurt. It only made her remember that she was just a sexual pet, one easily bent to Luka's will. To her, she was only a weak human who had to submit to every of her lustful wish.

Luka desired sex with Miku because of curiosity and the need to control her, since she hadn't been able to until recently. There was nothing more to it than that.

"Even after the night we just shared, you still treat me like I am nothing more than a—"

"Miku," Luka cut her off abruptly, the sternness in her voice effortlessly making her freeze. "Back off."

The small human's heart sank. Those two words were enough to make her forget how to breathe. The pain slowly engulfed her. Was she seriously telling her to back off now?

"You agreed to having sex with a succubus. I was merely using you to satisfy my hunger. I was never here to cuddle with you; you are getting irrationally emotional over it," The Queen continued, hopping out of bed. "I have noticed the affection you held for me while I was touching you. I am not blind, and by all means, get rid of those feelings."

Miku's throat tightened. Luka had noticed her growing affection? She supposed that she did make it a bit obvious. The princess was aware that she could be quite expressive, so Luka probably had been able to see it on her face. Her eyes quickly darted away as she struggled to pretend that it didn't bother her. Her lips trembled. Even if she knew she shouldn't be feeling this way, she couldn't help herself. Luka was terribly mean to her, and yet, Miku still believed that she wasn't as heartless as the other demons she had encountered in the past.

"What about you? You came back to me like you absolutely needed me to appease your hunger. You risked getting caught in humans' territory despite the upcoming war between our two races and yet you…you came back to me…"

The succubus stayed oddly silent for a minute, as if she was also trying to make sense of the situation. With a sigh, she ran her fingers through her tousled pink locks.

"I admit to having lusted over you a bit too much in the past few days," She simply answered. "However, it will not happen again. You have satisfied both my endless hunger and curiosity."

A sudden, sharp noise suddenly interrupted their little talk. They both stared at the balcony as a figure with horns and wings appeared. An imp. And judging by the murderous look on his face, he was not here to be friendly.

He quickly entered the room only to freeze as soon as his gaze fell on Luka, frowning at the scene in front of him: the Queen of Demons, naked with the human princess. Judging by the messy covers on the bed and the looks of exhaustion on their faces, they had unmistakably had sex.

"M-My Queen, I did not know you were here," He murmured, bowing in front of her despite the look of hatred and disgust plastered on his ugly features.

"Why are you here, imp?" Luka asked taciturnly.

"T-The King sent me to…" He paused for a few seconds, hesitating between telling the truth and lying. Eventually, he settled for the former, knowing that the Queen would force him to be honest anyways. "…to kill the human princess."

Miku tensed, the news immediately giving her chills. It had only been a few hours since Gakupo escaped, and he was already sending his subordinates to kill her? She pursed her lips. She should have thought that he would act as soon as possible.

"Return to demon territory immediately."

"I am afraid that it will not be possible, my Queen, the King made it clear that I must come back successful or-"

"Lay a hand on her, and I will make sure that you only know what suffering is. What do you prefer: a night with the King, as he probably promised you in exchange for your success, or years of pain? I will say it one last time: return to demons' territory immediately!"

Despite the fear she felt, Miku was shocked to hear Luka's usually smooth voice sound so harsh and authoritative. It was nothing like the playful arrogance and the indifference that she was used to. Somehow, with all the anger distorting her face, she looked more like one of her kind now than ever.

The strangest thing about the situation was how the succubus seemed to be protecting her, when she had no reason to do it anymore. Even with Miku dead, there would still be a war, and that was the main issue Luka wanted to avoid. Defending her was useless now.

The imp seemed to be irresolute. He was watching the human with a clear murderous intention, but he also visibly feared what the Queen would do to him if he were to carry out the King's order. Soon enough, he took a few steps back and nodded reluctantly.

"Engaging in sexual activities with a human will get you killed, my Queen," He whispered darkly. "Your betrayal will not remain unnoticed."

Without further ado, he spread his wings and jumped out of the balcony, fists clenched the whole time.

Luka then murmured an imminent threat under her breath, too low for Miku to be able to hear.

"If I weren't here, you would have been dead by now, Miku. You should position several guards in front of your chamber's door and on the balcony. It seems like my King is somehow aware of this unguarded entrance. He must have interrogated the imps who sometimes helped to bring me here," She scowled, her eyebrows furrowing ever so slightly. "One thing is for sure: he wants you gone as soon as possible, and he is ready to do anything for that to happen. His foolish pride cannot take such a defeat."

The teal-haired girl took a deep breath and tried to calm down. She had been right to think that things would not be simple from now on. The King of Demons wanted her dead, she was starting to develop serious romantic feelings for his Queen, and a bloody war was coming up. Things could only end in tragedy. No happy endings could happen for her.

It seemed like she has no other choice but to position guards everywhere near her chamber. However, doing so meant that Luka wouldn't be able to see her anymore, and she hated herself for letting that bother her so much when her own safety was certainly the top priority.

"I will try to keep an eye on him, but I cannot guarantee that I will be able to stop him from sending imps to kill you, so the rest will be up to you and your guards." The succubus explained as she approached the balcony, ready to leave.

"Wait!" Miku exclaimed as she dashed towards her, grabbing her wrist to stop her from leaving. There was one thing that she needed to know, one thing that she would regret if she didn't ask before they parted ways again. "Why do you worry so much about my safety? You needed me safe to prevent the war, and now that it is unavoidable, you have no reason to protect me."

The pink-haired demon remained unfazed. However, she stared off into the distance, seemingly lost in her thoughts. Finally, she sighed in defeat and pulled her hand away from Miku's grasp.

"Knowing that you could effortlessly be harmed or, worse, killed makes me a bit…tense."

Miku's heart beat faster, her face flushing gently. Luka was worried about her. She cared about her well-being. Did the succubus even understand that? She seemed to be confused when it came to tender emotions in general, often calling them weaknesses or others of the sort.

Since the succubus refused to meet her inquiring eyes, the princess hesitantly grabbed her face between her hands and forced her to look down at her. They silently stared at each other for a few seconds, and Miku could tell that the Queen was a bit uncomfortable with this turn of events, trying her hardest to not turn her head away from her.

"Are you worried about me?"

"No, I am worried about myself, not about you…" Luka said hesitantly. "Before you get the wrong idea, let me explain the situation. Recently, I have not been able to feed properly with others. The sex I had seemed…dull and unexciting. Ever since I touched you for the first time, I suppose I became hooked on the idea of making you…succumb to me. You are giving me such strong reactions; it is nothing like what I receive from my kind. I do not know when I will start to get tired of you, so until then, it would be in my best interests to keep you safe, in case you remain my only way of regaining my powers. I become weak if I do not get enough satisfaction."

The human frowned and finally let go of her, arms crossed over her chest. Miku didn't have a hard time believing her, but she felt like there was more to it than a strong lust. Was she really worth risking her life for? Once again, she tried to make eye contact with Luka, but she avoided it.

Miku puffed out her cheeks, slightly irritated with that strange behaviour of hers.

"You do realize that if I position guards on my balcony, you will not be able to come visit me for…um…that anymore, right?" Miku asked with a raised eyebrow. "For that matter, protecting me is useless since we will not be able to engage in…s-sexual…activity…"

Luka snickered, visibly amused by all that stammering, which only made the teal-haired female even more frustrated and impatient with the situation. She was about to voice her annoyance but gasped gently instead as the pink-haired seductress grabbed her by the waist to pull her close, pressing against her naked body and looking down at her with the teasing smirk that always made her heart skip a beat. That mischievous look on her face always succeeded in making her knees weak. It was mysteriously seductive.

"Why are you getting embarrassed about mere words when you were straightforwardly pleading me to touch you earlier?"

The human tried to glare at her despite being flustered at the sheer mockery. She didn't like how Luka had changed the topic, and she felt like she was doing it on purpose. That succubus always knew how to shut her up effectively. And of course, the moment she opened her mouth to try and get angry at her again, Luka ran a finger over her belly button, tracing a pattern on it and giving her electrifying sensations. She made Miku submit so effortlessly, almost mocking her by showing that she was permanently the one in control.

Miku bit down on her lip. She was more than aware of Luka's incredibly soft skin against hers, their nipples brushing together lightly, sending jolts down her spine. She hated how the simplest touches made her desire so much more, especially when she had already had enough earlier. She would pass out from exhaustion if she allowed things to go that far again, so she grabbed the taller female's shoulders and pushed her away, the beginning of arousal visibly making her edgy. It wasn't her fault if that damned succubus made her feel so good under the blankets; the pleasure was too addicting for her own good.

"Getting aroused again, little maiden?"

Miku knew very well that it was futile to deny it since Luka could sense when she was turned on. She stepped away and took a trembling breath. It was insane how she never cared about sex before, and now that she had discovered just how much of a sex drive she had, it made her feel almost guilty for being so…avid. Right now, she just wanted to push the succubus down on the mattress and make her lose all her foolish pride. It would be best if she changed her train of thought as soon as possible.

Though, she quickly made the mistake of staring at Luka again; her breath caught in her throat and her heartbeat accelerated dangerously. The morning sun illuminated her naked body, bathing it in a soft, orange light. At that angle and with the way she was standing, one hand on her hip and the other tangling with her pink hair, she looked utterly stunning.

Her teal eyes traveled down Luka's body almost hungrily, examining every one of her mature curves. Since Luka could probably see how captivated she was, she gave the most alluring smile she could make, causing the scene to look even more flawless than it already was. Miku honestly wished that she could forever etch that image in her memory.

After a minute of complete silence, the human finally found the courage to stare away, clearing her dry throat. She couldn't believe how hard her heart was currently beating. She was troubled, disturbed by this gorgeous demon who continuously made her lose all sense of rationality. She wished that she weren't so weak to her charms; it constantly made her feel like she was under a permanent spell even though she knew that the succubus wasn't using her powers on her right now. It was strange since she had more resistance towards her charisma before; she had been able to push her away more easily, to not let her constant teasing and flirting affect her too much. She was becoming more vulnerable because of her escalating romantic and sexual feelings, and she absolutely hated to admit it to herself.

"Miku…"

Her name had been whispered in a husky, low voice; one that sent her chills. When she looked up at Luka, her heart instantly raced in her chest, and her throat tightened. Miku had never seen such a sweet expression on the demon's face before; Luka stared at her with soft eyes, her features very relaxed and enigmatically gentle. She was almost showing some fondness, some affection. The princess was so used to seeing a flirty expression or a cold and indifferent one that seeing such softness on her face almost made her head spin. Her whole body went numb from shock. There was no doubt about it —Luka looked so much prettier when she displayed tenderness.

In this fleeting moment, Miku was aware that she was falling in love. How else could she explain the sensation of having butterflies in her stomach? How else could she explain the fact that her heart was beating like she was running a marathon? How else could she explain this strange feeling that time stopped only for this moment to exist?

Soon, a knock on the door immediately made her return to reality. She froze in place, unable to avoid the sudden fear she felt about getting caught talking with the Queen of Demons. With the rumours going around about her having an affair with the succubus, it would be in her best interests to not make things look even more suspicious than they already were.

"Your Highness?" The maid spoke through the closed door.

"Y-Yes? What is it?" Miku tried her best to sound normal, hoping that the crack in her voice wasn't too noticeable.

"The King and the Queen asked for your presence at the dining hall immediately."

The princess looked at the time and her eyes widened. She was late for breakfast, and her parents absolutely hated when she made them wait. She could already hear her mother's cold voice reprimanding her unacceptable behaviour.

Miku ordered the maid to tell them that she would be there in a moment before quickly going through her wardrobe. She took the most attractive dress that she could find, dressed up as fast as possible and looked at herself in the mirror, grimacing at her reflection. It was evident that she didn't sleep last night. Her eyes were sunken and slightly red. She would have liked to take a shower since she sweated a lot in the past few hours because of a certain succubus, but she knew that she didn't have enough time. She barely had the time to brush her long hair properly. She was a real mess.

An amused chuckle made Miku frown in anger.

"You look like you had a very long night," Luka commented, looking her up and down with amusement.

"And whose fault do you think that is, succubus!?" The teal-haired female exclaimed, turning around to face her, clearly not in the mood for her teasing right now. "Y-You could not keep your hands to yourself even after I told you I had enough! Now I look like a mess, and my parents are definitely going to question my appearance!"

"Even though you told me you wanted to stop, it was not what your mind and aura told me." The demon said with an unrestrained yawn, exhaustion also plastered on her face. However, it didn't stop her from making suggestive gestures with her fingers, as if to remind Miku exactly what had happened between them. "You should learn to be more honest. Even with current circumstances, you do not regret what happened last night."

That damned succubus always had the last word, and Miku hated how much she knew about her. She could never deny anything even though she wanted to. It was frustrating at times.

She growled in defeat and headed towards the door, ready to leave, but then she stopped in her tracks, hesitating. As soon as she was gone, Luka would leave her again, wouldn't she? And since she was going to put protection all around her chamber, they wouldn't be able to meet anymore. She tried not to wince at the unavoidable pain, the pain that reminded her that whatever she felt for the succubus wasn't purely sexual.

"You are free to leave now if you so desire, but I would like us to talk about…something that has been on my mind. I will be back in an hour, so if you decide to wait for me, you can rest on my bed. No one is allowed to enter my chamber without my given permission."

Without waiting for an answer, Miku left and closed the door behind her, unable to restrain a sigh from escaping her lips. She could only hope that Luka would decide to stay. It wasn't just her physical appearance that was currently a mess, the whole situation was, and they needed to talk about it before their inevitable separation. Maybe it wasn't love that the demon felt for her, but with the way she looked at her earlier, she definitely wasn't…indifferent. At least, Miku was certain that Luka felt a bit of fondness towards her even if she hated the thought, but that feeling was mutual —Miku also disliked how involved she got. Luka was a demon, the Queen of Demons, one of the kingdom's strongest enemies. She shouldn't be feeling anything close to friendship towards her, and yet, she was starting to fall head over heels for her. It was disastrous.

As soon as she entered the dining hall, she was greeted with her mother's most exasperated face and her father's disappointed one. She decided to ignore them as she sat down at the table. She didn't listen as the Queen reprimanded her for being so late, as she lectured on about how the heiress to the throne should be more responsible than that. It was only prattling about things she already knew.

Miku only realized how hungry she was when she dug into her breakfast. She supposed that it was mostly because of the…rough night she had. It completely drained her energy. Miku made a mental note to bring food to Luka after she was done eating; she must be just as hungry. She often brought food to Rin anyways so it wouldn't look suspicious, although her parents always disapproved of her spoiling the maids. It was still better than throwing the leftover in the trash, after all, but she sometimes doubted her parents even knew what compassion was. They weren't better than the demons in regards to that matter.

"Did you have difficulty sleeping, dear? You look like you have not slept well," Her father said with concern, trying to break the awkward silence. "The recent events must be worrying you a lot. Though, you can rest reassured, your mother and I will take care of everything; you will not need to get involved in the upcoming war. I do not want you to. Therefore, we decided to postpone your marriage with Shion. We cannot make you Queen when things with the demons are in such a crisis."

"You should stop babying her," Her mother sighed, massaging her temples as if the conversation was giving her a headache. "Since you keep spoiling her, she is not able to be independent. She should be helping us prepare for the war, or she will not learn."

"The King of Demons almost killed her! We cannot involve her further than this! For her safety!" The man slammed his fist on the table, apparently tired of his wife's behaviour. "We had this conversation many times already. We are not going to involve her."

Miku looked down at her plate. She should have expected that. Her parents never agreed on things when it came to her. One was too protective of her, and the other barely cared about her safety. Even though she was relieved that her wedding with Kaito was suspended for now, the possibility of her participating in the upcoming war was another source of stress she would have to deal with; that, and her parents refusing to get along when things were rough.

"I think the King wants her death because she is having an affair with his Queen. Why else would he want to harm her?" The hard-hearted woman clarified, throwing a doubtful look at her daughter, especially after the princess noticeably tensed up at the accusation.

"Do not be ridiculous! He wants to kill her because he knows that she is the heiress of the throne! He said that only to destabilize us. Do you truly believe our daughter capable of doing such a shameful thing? You know better than I do how those vile demons are; they are good at manipulating us with words!"

The princess had enough. Without saying anything, she stuffed her plate with slices of bread, fruits, and meats before getting up to leave the dining hall, ignoring her parents as they told her to come back and not bring food to her room. Sometimes, she earnestly wished that she could leave her responsibilities and run away to live a reckless life, never to return. She had thought about it so many times, but she knew that it was impossible. Escaping was not as easy as it seemed. Still, she felt like if she stayed in the castle, things would become tragic, fast. The King of Demons wanted her dead, she was starting to develop serious feelings for his Queen, and, if proof that she was indeed having an affair with Luka were exposed, she would most likely be given the death sentence for three reasons: treason, forbidden commitment with a demon and homosexual behaviour. Her life was, no doubt, in danger.

Miku entered her chamber and closed the door behind her. She expected Luka not to be there anymore, but she was surprised to see that it wasn't the case. The succubus was sitting on her bed, noticeably sleepy. It was almost adorable to watch the usually emotionless demon nodding off like that. Although Miku couldn't blame her since they had a long and exhausting night, after all.

Miku put the plate of food on her bedside table and hesitantly sat down beside her, staring at her feet almost sheepishly. Things were always awkward between them when they weren't having sex and tried to have normal conversations.

"The food is yours. I thought that you might be hungry."

Miku didn't need to tell her twice. As soon as she said that, Luka started to indulge in the expensive food like she hadn't eaten anything in years. It wasn't so surprising since demons had trouble finding decent food in the first place. She was pretty sure that they often stole from her kingdom. Even then, the succubus still tried to feed Miku when Gakupo had kidnapped her, so it was only natural for her to return the favour.

Miku lay down on her bed and stared at the ceiling almost absently. She couldn't stop worrying about the eventual possibility that her mother would discover that she was truly having an affair with the Queen of Demons. Things could become hellish very fast. She hesitated before speaking her mind, but went ahead with it, since it also concerned the succubus.

"Mother suspects me of having an affair with you. Your King told my parents that we were having sexual intercourse, and she believed him."

"She has no proof, so she cannot do anything about it," Luka replied almost instantly as if she didn't need to think about her answer for even a second. "Besides, once I am done eating, I will disappear from your life. We will not be caught together."

"You keep contradicting yourself," The teal-haired girl mumbled, frowning. "Earlier you said that you wanted to protect me in case you needed me to regain your powers, but now, you confirm that you are alright with leaving me. Which one is it?"

The Queen turned her complete attention to the food, disregarding the question. She was avoiding it again. Miku felt like Luka didn't know the answer herself. She sat up and crossed her arms over her chest. One thing was certain though, Miku didn't like being ignored like that, and she would certainly like to know how Luka felt about her. Was she seriously only a way for the succubus to regain her powers? She highly doubted it, especially after seeing the caring look Luka gave her earlier.

The human then slowly, almost teasingly ran her thumb down the other female's spine, amused as she saw her tense up. It was even enough to make Luka drop her food.

"You mock me for reacting too much, but you are also quite sensitive, are you not? I noticed you shiver when I accidentally scratched your back while we were doing it." Miku boldly stated. It was payback for all the relentless teasing. However, there had been something else that she was curious about. She swallowed hard before hesitantly grabbing one of the succubus's horns, touching the edge with interest. "You also get oddly uncomfortable when I do this…"

Luka abruptly turned around and pinned her down on the mattress, grabbing both of her hands to stop Miku from touching her. She glared at the princess, even though her face was slightly flushed. Was she… blushing? Was it from embarrassment or was it simply because she was angry? Miku couldn't tell, but it was enough to make her heart skip a beat, stunned by the new expression.

"Grabbing my horns is no light matter!" She growled furiously, her eyes meeting Miku's teal ones.

"Why?" The princess blinked, wondering what the big deal was.

"It means dominance, it means that you have complete control over me, and there is no way I will let such a puny human grab me by the horns!"

Miku's eyes widened. Demons judged them for being too…human, but they also had their weaknesses. Little did the succubus know, this piece of information made her want to touch those horns even more. Miku had always liked the thought of making Luka lose her tremendous pride after all. What if that was the only way to make her less confident? Or to make her understand that she wasn't as obedient as she appeared? Her heart beating harder in her chest, Miku managed to free her hands from the demon's grasp. She then pretended that she wasn't affected by the news, even though she actually had an idea in mind. She only had to find a way to prevent Luka from pushing her away.

Without saying anything, she stood up and quickly searched for a solid piece of cloth. Once she did, she approached the Queen and grabbed her hands, hastily tying them together with the cotton scarf she had found. Before Luka had the time to question her, Miku pushed her down on the bed and grabbed both of her horns, looking her directly in the eyes. Surprise was the first emotion to appear on Luka's face before it quickly transformed into disconcertment as she realized the weight of the situation.

As the princess thought, the succubus couldn't use her powers when her horns were being held. It was as if she couldn't completely focus on the task, most likely because the act troubled her so much that she had difficulty concentrating. She knew that sex demons played with others' minds by focusing completely on them, after all. If she had known beforehand that it was, in reality, this easy to make her vulnerable, she would have done it earlier.

The human felt a great sense of superiority fall over her. This farfetched situation was boosting her confidence considerably. She was doubtlessly enjoying this. Even the exhaustion she felt earlier was gone due to adrenaline.

"You are not struggling much," Miku remarked after a minute of silence, extremely entertained. "Are you actually enjoying this? The idea of being dominated by a puny human?"

There was a faint spark of anger in Luka's eyes. However, it was also mixed with humiliation and embarrassment. Her lips were tightly pressed together, growls constantly escaping her mouth. She seemed to both disapprove and agree with the current turn of events. While her face showed discontentment, her body noticeably became hotter at the thought of the possible outcomes if things continued like this. She also remained motionless when she could have tried to struggle, despite being tied up. Luka wasn't telling her to stop either. She definitely consented, even if it seemed to be humiliating her somehow.

The teal-haired girl's heart couldn't stop pounding. As much as she enjoyed having control of things for once, she couldn't help but feel a bit nervous. She had fantasized about this moment so many times in her mind, the moment she would finally be able to touch her. Nevertheless, she had no idea what she was supposed to do or how to start. More importantly, Luka did tell her that she wouldn't be able to make her feel pleasure at all. What if it was true? Or what if she had just tried to scare her away from doing it? Whatever it was, she shouldn't let it stop her from attempting.

With one of her hands firmly gripping Luka's left horn, the other one slowly trailed down her neck, caressing gently with the tip of her fingers. She thoroughly examined the succubus's face as she reached one of her breasts, pressing her palm into it. She immediately enjoyed the softness, as well as the slight firmness that they had. The sensation was nothing like feeling her own breasts, which were too small and barely felt squishy as a result. She could easily squeeze Luka's in her hand, and needless to say, Miku plenty enjoyed doing so. She would have played with them more if it hadn't been for the succubus's visible irritation with her endless curiosity. However, while touching Luka's left breast, the petite girl noticed that the succubus's heart was racing wildly. She felt it beat hard and fast against her palm.

It was easy to tell that Luka wasn't completely indifferent to her caresses since her skin was growing hotter by the second and her eyes were showing mild hunger.

Feeling bold because of the compliant behaviour the Queen showed her, Miku drew close to Luka's ear and whispered:

"You always act all high and mighty with me, constantly reminding me that humans are inferior to demons, but look at you now, quickly succumbing to me and enjoying my caresses… I think, even if you do not like it, you lust over the idea of a mere human like myself touching you. I might not be able to sense auras like you do, but I do see the beginnings of hunger in your eyes."

Luka turned her head away, glaring fiercely at the wall. She didn't speak a word, apparently bothered by her own weakness. The princess felt a bit guilty for humiliating her like that, but she was tired of the unshakable confidence that often made her feel like humans were weak and pathetic. It was about time she had her little vengeance.

Miku caressed the demon's stomach without letting go of the horn she resolutely held. She felt herself blush as soon as she explored the succubus's most intimate part. As much as she had wanted to appear confident, being in charge still felt somewhat embarrassing. Not only that, but Luka was already wet, only confirming her earlier statement about how the situation was turning her on despite how dreadful it could be for her.

She took a deep breath. It was all right. She knew what felt good and how to do it. She learned it by doing it to herself and by taking notes of what Luka did to her. She only had to imitate her; it was as simple as that.

Then, gently, she grabbed Luka's clit between two fingers and squeezed it before moving up and down, sometimes going on circular motions, alternating between the two. Immediately, she could see the succubus tense up, her toes curling up and her teeth biting her lower lip as if to prevent a gasp from escaping. Judging from the occasional quivers and twitches that took over the demon's body, Miku could quickly conclude that she was indeed receiving pleasure. Nonetheless, it was a bit frustrating since aside from that, she wasn't reacting much. She couldn't guess what she thought at all.

"Does it feel…good?" The princess decided to ask, looking her right in the eyes without stopping what she was doing, even picking up the pace.

Upon being asked, Luka instantly averted her gaze, remaining quiet. The human frowned, slightly irritated with the unusual silent behaviour. However, after scrutinizing Luka, Miku could swear that the succubus was blushing. Her cheeks were a very soft red. It was barely noticeable, but it was still there. Funny, since she was the one who had said that demons didn't feel embarrassed and now here she was: a succubus blushing during sex; unusual, but very adorable. She wondered whether it was caused by the fact that she was human or because it was her. She hoped that it was the latter.

"…You can put more pressure on your touches…do not be scared of being too rough…" Luka whispered between trembling breaths, trying to guide her despite how humiliating it seemed for her to do so.

The princess nodded, affection filling her eyes. It looked like the succubus enjoyed it rough, though it probably took her some guts to admit it. So, she did as she was asked, stroking Luka's sensitive bud harder. She was still unsure of what she was doing, but her confidence increased as soon as she noticed that Luka was reacting a bit more; her breathing was starting to get ragged and uneven, transforming into gasps, she was also whimpering quietly and sometimes her whole body moved involuntarily.

Miku was amazed by the reactions she received. She couldn't help but find it incredibly enticing. She might even become addicted. She was starting to understand the succubus's obsession with "making her react" while they were having sex. However, she soon noticed that her fingers were starting to cramp a little, and holding the horn constantly was also strenuous.

Miku had to stop for a moment, completely letting go. Much to her surprise, Luka didn't try using her powers, now that she was "free". Instead, she stared up at Miku with faint confusion, wondering why she stopped and obviously becoming more frustrated as seconds passed. It seemed like she didn't need to grab her horns anymore.

"Do you want me to continue?" The human asked mischievously, strictly teasing her at this point with a seductive grin.

Luka groaned, scowling at her.

"If you are going to continue, at least, do it properly. I will not orgasm simply with these amateurish caresses that you are giving me."

Miku nodded. She supposed that she could do what the succubus usually did to her. Besides, she had honestly always been curious about that. She trailed kisses down Luka's stomach, her heart beating harder in her chest as she realized that she was going to give oral. She found that to be a bit embarrassing.

A blush played on her cheeks as soon as she shoved her face between Luka's legs. Before starting, she stared up at Luka. The succubus watched her with amusement, that typical arrogant smirk of hers parting her lips yet again. Maybe not letting go of her horn had been a good idea, after all….especially if it prevented Luka from acting so high and mighty.

"Too embarrassing for you, dearest?"

"I… I can do it!" Miku exclaimed back, glaring to show her resolve.

Without further ado, she gave long, rough lick, satisfied to see that it was enough to make the female demon twitch. Since Luka made it clear earlier that she didn't like it gentle, Miku licked her clit avidly, pressing her tongue against the sensitive skin as much as she could and going at a fast pace. Almost instantly, Luka's breathing started to alter to irregular gasps as she parted her legs further for the girl to have better access to her intimate area, finally indulging herself in the pleasure.

Miku decided to close her eyes, trying to guess whether she liked it or not just by listening to the changes in her breathing and feeling the shudders running through her inner thighs with her free hand. Eventually, she thrust two fingers inside. It took her some time to find the right spot, getting her clue as to where it was as soon as Luka's breaths became shorter and quicker. A low, alluring moan escaped the succubus's mouth. It looked like Miku had found the famous spot. Roughly, she pushed into it.

"Y-Yes, right there… G-Go faster and harder…" The pink-haired demon demanded.

Miku obeyed, thrilled at the thought of finally making Luka feel good. It didn't take long before a few moans indeed filled the room. When the teal-haired girl looked up, her heart skipped up a beat at the expression Luka wore. Her lips were tightly pressed together as if trying to restrain her groans as much as possible and a blush was visible on her cheeks. It was as if she was too prideful to show that she was actually enjoying it a lot. An inexperienced human could give her decent pleasure after all! Still, seeing her like that was truly endearing, and Miku doubted that she would ever get enough of that.

At long last, Luka reached her orgasm, her body overtaken by gentle spasms as she whimpered from pleasure. The teal-haired princess then pulled her fingers out and brought them to her lips to lick them clean. The succubus always did it after she made Miku climax too, often giving her a sly, flirtatious look each time, which always effectively embarrassed her. She gave the demon a proud grin, happy that she succeeded in giving Luka an orgasm. She had seemed so sure that Miku wouldn't be able to, after all.

"Untie me at once…" The Queen of Demons finally growled as she tried to catch her breath.

Miku thought it would be better to do as she was told, since Luka seemed a bit annoyed, and she doubted that it was a good idea to make the most powerful demon mad at her. Once she finished untying her, Luka didn't waste time. She swiftly pushed Miku down on the mattress, making the bed crack under their weight. Despite looking angry, she still appeared to be ashamed of the recent events, her cheeks a soft red.

"Turn around and bite into your pillow as forcefully as you can."

The girl blinked and timidly submitted. She knew where things were going, and even though she was quite exhausted right now, she decided to obey. The Queen seemed genuinely troubled by her own weakness, and it made Miku a bit guilty for having pushed her. She wanted to soothe Luka, even if it meant having sex again.

She took a deep breath before biting onto her pillow. Admittedly, the thought that Luka wanted to have vengeance for what happened by showing who was the leader in bed was quite exciting. Despite her tiredness, she couldn't help but look forward to it. It was why she didn't resist when the pink-haired beauty lifted her dress and pulled her panties down. However, she was shocked as soon as she felt her use her powers on her. It was a lot more than usual. She could barely think straight as the welcome warmth enveloped her; it even made her feel a bit dizzy.

"W-Wait…" Miku panicked as she realized that maybe this was a bad idea. "I…I do not think I can handle this much right now…"

"Just relax. It will not hurt you," Luka whispered, reassuring her. She came close to Miku's ear, hot breaths making the princess shudder excessively. "However, be prepared. It will only take around thirty seconds to make you orgasm, but those thirty seconds will be very extreme."

The human swallowed hard. Even though she was worried that it might be too much for her to handle, she still found herself insanely aroused at what was coming next. She clenched the bed sheets tightly and bit onto her pillow as she was advised to do, preparing herself.

The succubus went straight to the point. Her fingers reached Miku's clit, and she stroked it as quickly as she could. Miku didn't know what exactly happened during those thirty seconds. All she knew was that her mind went completely blank and the only thing she had been able to feel was unbearable, intense pleasure. She also remembered having shrieked and screamed into the pillow, and her entire body had been quivering the whole time. And once she had reached her climax, she was nearly sure that she had passed out for a few seconds. All she was aware of was that once she came back to her senses, she was still shuddering from the after pleasure.

Luka had been right to call it "very extreme." Miku didn't think she would feel sex this intense ever again. She lazily turned around and was surprised to immediately find intrigued blue eyes. The demon was so close to her right now, their faces only inches away. They silently stared at each other for the longest time, and the human swore that her heart was going to burst out of her chest. She was also sure that her lungs stopped giving her breath for a few seconds. Luka was so gorgeous up close, and the passion and beguilement in her gaze made everything even better.

Their lips eventually touched. The kiss started out gentle and chaste, but quickly became more urgent and needy. Both females pressed their bodies into each other with the overwhelming urge to be as close as possible. Miku didn't even know who had initiated the kiss, but she didn't care, she only cared about the multitude of emotions assaulting her, the ones that confirmed for good that she had genuine, romantic feelings for the succubus. While sex with her felt very intense, the kiss made Miku feel alive; it made her feel like she belonged to Luka, like she was meant to share this tender, yet passionate moment with her.

Miku couldn't restrain a whimper when their lips finally separated. She had wanted to continue kissing Luka. However, she was soon alarmed once she noticed the succubus's distress. The kiss wasn't what seemed to bother her, but it looked like she was scared of the fact that she had allowed things to get this far.

Wanting to reassure her, the human caressed her cheek with the back of her hand, giving her a soft smile.

"It is all right, Luka, we—"

"It is not fine! For a second, I forgot that you were a human, and I…" The succubus paused as she stood up abruptly, grabbing her outfit and putting it on. "I…I do not understand what is happening to me…but this situation, whatever is going on right now, it cannot continue…"

The princess's heart sunk in her chest as soon as she heard those sharp words. Of course, Luka would reject whatever she was feeling towards Miku. Her pain only amplified when she saw that the demon was heading towards the balcony, seemingly determined to leave her, to leave whatever was happening between them behind.

"W-Wait! Let us talk about it properly! Please, do not leave now, we…we…"

The Queen of Demons didn't let her finish her sentence. She was already gone. Miku couldn't even describe how hurt she was. She felt like she couldn't breathe, the compressing pain in her chest refusing to disappear for even a second. Just when Luka had possibly realized that she was developing feelings, she had decided to leave.

And who knew if she would come back this time.
