【New Express ABO】Mistake

Something... not quite right.

Kudo Shinichi struggled uncomfortably in the darkness, his forehead was touching the brim of the white top hat, and the top hat was tilted.The owner of the top hat was still on top of him, and was peeping out from the cramped electric well through a gleam of light from the crack of the door. Because his vision was affected, he silently pinched Kudo's shoulder, signaling him to calm down.

There were footsteps passing by outside the electric well, Kudo couldn't see outside, the only narrow gap was occupied by Kidd, Mr. Thief's chin rested on his shoulder, he turned his head sideways, and could only see the The thin strip of light reflected on Kidd's face at close range.At this distance, the monocle has no blocking effect at all: the eyes are gray-blue similar to his own; the eyebrows are wrinkled, and it seems that the prisoner outside has not gone far; you can see the fine hair on the side of the cheek—— Useless information that cannot be further reasoned, why did you notice it; more intelligence——can’t be observed, damn it, if it weren’t for the narrow hiding place found under this emergency…

Kudo felt a little irritable and tight in the chest.

This time it was indeed Kudo Shin's carelessness.He easily saw through the fact that the warning letter sent to the police station was a fake, and after carefully inspecting the scene, he also deduced the purpose of the criminal pretending to be Kidd. It would have been impossible for an accomplice to act as a bait to distract all the security forces, but if the famous "Kidd" was the bait, the situation would be quite different.

Although they have seen through the intentions of these lawbreakers, if the fake Kidd who served as the bait is cleaned up in advance, the remaining gangsters may not show up.So Kudo chose to use his tricks and let the police officers of the second search section pull on their sirens to hunt down the fake Kidd for thousands of miles. Then, when the robbers showed up, he slapped the only proprietress who stayed in the store aside, and smugly grabbed the counter When he stuffed the jewelry on his backpack into his backpack, he walked out of the door unhurriedly.

"You guys seem very complacent about your criminal plans," said the young detective.With a fearless smile on his lips, one hand clasped on the knob of his football belt, he walked slowly towards the prisoners, "Let an accomplice put on a hang glider to lure the police away, and the rest of the jewels are in the bag." You can also put the blame on Phantom Thief Kidd by the way—that's the plan, gentlemen of fakes."

— So far so good.

The bad part is that the robbers this time are different from the good-tempered prisoners who are willing to listen to the reasoning show in the past. A few grumpy guys just pulled out their guns and shot without even a warning, and one of them even "dropped" Press a button with a bang, and the next second the rolling shutter door of the jewelry store will be rumbled down.

Oops!

At the fastest speed, Kudo rolled behind a counter in an extremely thrilling manner, narrowly dodging the first wave of fire.Before he could think about what to do next, he heard a few roars from the robbers, a white figure flew towards him like a wind, a smoke bomb fell, and then he pulled up Kudou and ran away.

"Kid?!"

"Shhh! Let's talk about it when it's safe, this way!"

This is the cause of the incident. The robber this time may be the most promising class that the teacher has taught, forcing a pair of old enemies to curl up and stuff themselves into the narrow electric well, while the villain with a pistol The disciples were spinning around separately, trying to pull them out and kill them.

It can be said that it is a critical moment of crisis.Fortunately, the hiding place was chosen cleverly—they never expected that there would be two big men hiding in such a small place, Kidd explained when he stuffed Kudo into the electric well.

Kudo felt that it was so fucking reasonable. He never thought that this place could really fit two people. If he was still Conan, it would be much easier.Now they are squeezed together head to toe, with most of Kidd's weight on top of him, forming an overly intimate neck hug, the pendant on the monocle still hanging on Kudo's shoulders and neck, the four-leaf clover The pattern on the skin on the back of his neck is cool.

Something is not quite right.

Kudo took a long breath, trying to calm his breathing rate and his heartbeat that was a little too fast.But he can't.The heart was beating like a drum in the chest cavity, and the air inhaled into the lungs failed to relieve it, but made people more and more anxious.This is not normal.

Not because of Kidd's weight on him.Kaitou is very light, after all, he has a thin body that can't be found even if he is dressed as a woman. When returning Ryoma's treasure, Kaito's slender ankles became a breakthrough point. went.

It must be because the electric well is too stuffy.

"The police department has been notified, but they chased the fake Kidd too far, and it will take a long time to get back." Kudo said in a low voice.This posture is very convenient for whispering, and the thieves outside will not hear you if you whisper.

Kidd let out a "huh" and still focused on observing the situation outside the door.

Kudo was subtly upset, and changed the subject: "The shop owner's wife who insisted on staying even though the most valuable jewel in the shop was stolen, is really you pretending to be."

"Ah, after all, the name has been used by fraud. It's not good if you don't stay here to teach the counterfeit a lesson. Although your eyes sharpened when you looked at me on the way...you remained silent until the end, anyway, thank you." This time when Kidd replied, Kudo suddenly felt a little strange sense of satisfaction, which made Kudo frowned.After a while, Kidd chuckled happily, and his voice exploded in Kudo's ears: "It seems that they have concealed it. Those guys have a lot of guns in their hands. If it's safer, they can hide them here at the police station." Come back, or when they leave the building to get away . . . what do you think, detective?"

The tone was relaxed, as if Kudo was the only one who felt depressed.Realizing this, the detective tilted his head stiffly. Compared with his breathlessness, the breath sprayed by Kidd on his neck while whispering was more difficult to ignore.Kidd seemed to have noticed this movement, thinking it was due to his own weight, he supported the wall with one hand and pushed his body up a little bit, then lowered his head and asked, "Is it on you? Can you hold it?"

Kudo opened his mouth, wanting to say that it’s not because of your weight—but what’s the reason? There must be something wrong with his state, a small, insignificant problem and a cold, but he can’t explain it himself , It was unnecessary for Kidd to waste his energy for no reason for such inexplicable reasons. In the end, he just shook his head and said simply: "It's okay."

So the weight came back, and at the same time, the heat of another body came back, and the strange sense of satisfaction when Kidd's body leaned over came back for a moment.The monocle pendant was attached to the back of Kudo's neck again, and it felt cooler than before, very comfortable.

--wrong.This is impossible.

The pendant has been attached to my skin for a long time, and it should have become warm long ago. Even if it just left the skin for a short time, the heat dissipation cannot be so fast, unless...

Kudo's body trembled.Sweat dripped down the bridge of his nose.Very bad feeling.

It wasn't that the pendant became colder, but that his body became hotter.

Ah... Speaking of the location of the pendant, it happens to be near the glands of the secondary sex characteristics...

He smelled the faint fragrance of flowers, like living things, spreading, growing, and blooming, showing a stronger and stronger sense of existence in the cramped space.

Kaito Kidd is an alpha.

In fact, this information has long been widely known, and even sympathetically, it is the only personal information related to Kaitou Kidd recorded by ICPO.When Kidd revealed his second gender, he didn’t even get the name kid. Everyone just knew that the phantom thief 1412 had the habit of conjuring flowers from his fingertips, and took the faint scent of flowers as evidence of the magic props hidden on his body. Until an omega police officer who was assisting in the defense reacted to the scent - it was limited to a physiological reaction of the degree of body heat, rapid breathing, and flushed cheeks, but it was enough to become ironclad evidence.

After this mistake, the strange thief carefully hid his pheromones, even if he was attacked by unscrupulous enemies with pheromone chemical weapons, he would not reveal his flaws at all, just like a beta.He still occasionally leaves bouquets of flowers at the scene, and some scents are attached to the teaser letter, but after identification, they are just ordinary floral scents and do not contain pheromone ingredients.Kudo has also verified this point himself. He had smelled it when he was still Conan. At that time, he was thrown from the airship. Kidd immediately jumped down and hugged him in his arms— —Of course, it is impossible for an undifferentiated child to smell any pheromones. The only explanation is that Kidd sprayed himself with perfume or something like that to cover up the pheromones.

So this time, even though Kudo had already smelled the familiar scent, his brain ignored it as useless information.

However, the current situation shows that: that is definitely not something that can be ignored.

"——!" Kudo's breathing rate has exceeded the normal range. Compared with breathing, it should be said to be a silent gasp.He raised his head to absorb more oxygen, but the fragrance of the flower sneaked into his throat and into his lungs, like the smell of roses, clear and cold, empty and silent, reminiscent of the flowing moonlight, the magician under the moonlight With a smile on his face, he snapped his fingers, and his lungs, heart, liver and kidneys burned together.

Extreme desire, and sexual attraction.

Kidd's body stiffened, he propped himself up so that the detective would stay away from the source of the influence, his poker face was broken, and he asked in a rather surprised and even flustered tone: "Detective, you, you are not beta ?"

Kudo had a bitter expression on his face, clenched his fists tightly, and fought fiercely with his own body—the instinctive reaction clamored for him to go up and hug the strange thief's thin waist immediately, and don't let the source of the pheromone leave—gritting his teeth Said: "I haven't differentiated before... Well, damn it..."

Everything has been clearly revealed, the small space, the accumulated pheromones, the abnormality of his own body, the inexplicable attention to Kidd and the desire for his body, and finally the fact that Kaito Kidd is an alpha—— Differentiation may be induced under the influence of pheromones of the opposite sex.

Kudo felt his face burning up, and whispered, "Sorry, I seem to be in my first estrus. The original plan can't be used, we have to go out...how is the situation outside?"

If it were someone else, Kudo would have already rushed out of the door, and the lonely A widowed O would be induced to divide in the same room. This is a scene with a high incidence of criminal cases.But if that alpha is Kaitou Kidd, Kudo has the confidence that he will never take advantage of others, so he has the leeway to continue thinking about dealing with the criminals outside.

Kidd was silent for a while, then as if trying to calm down his emotions, he took a long breath.When he spoke again, his voice was a little hoarse than usual, the content was still calm, and the tone was reassuringly relaxed, but Kudo could feel his breath becoming hotter.

"Judging from the sound, the patrolling guy has given up, and he is probably searching for loot in the hall now." Kidd put one hand on the door of the electric well, and slowly pushed it away, the gradually expanding light shone on his face, It's still the same poker face with ease, with a wonderful smile hanging on the corner of his mouth.He narrowed his eyes very happily, and gently tapped Kudo's lips with his right index finger through the white glove, "Please rest assured, detective, thanks to you, I am in excellent condition now. Leave it to me next, It will be resolved soon."

Kudo's mind went blank for a moment.

Damn it, this bumbling thief.

During the short time he was in a daze, Kidd pushed open the door and jumped out. Kudo grabbed the door frame and pulled himself up to catch up, but he was temporarily dazzled because of the huge difference in the light inside and outside the door.When the vision was restored, the snow-white cloak was flaring up and disappearing around the corner.He ran after him without hesitation, his body was still in a high state of excitement, but it was incredible that it did not affect his actions at all. Kidd's pheromone was floating in the wind very clearly, and he ran forward chasing the wind.

Kaitou Kidd's free and unrestrained laugh came from beside his ears, and there were sporadic gunshots and roars to embellish it.

Kuroba Kaito almost died laughing.

No, it's better to say that he almost suffocated laughing.

You really can't blame him for this.When you are an omega, you find that the enemy around you who thought it was beta suddenly started to release strong alpha pheromones, and you are so frightened that the enemy thinks that you have been tricked and will be killed on the spot. As a result, Mr. Enemy looks tangled and even a little bit Shyly say I’m sorry, I seem to be in heat, and you managed to get the brain circuit of how he reasoned to the wrong conclusion—I had to be silent for half a minute and take a deep breath to keep myself from laughing until I lost control of my expression management, which is also very sentimental Excusable thing.

Yes, Kaitou Kidd is alpha-this is completely correct information when the man in the middle was still the Black Feather Pirate One (although it does not apply to the second-generation Kidd), plus the Nakamori Police Department talked about this information When he is very, very uncommonly convinced, Kaito Kuroba can fully understand why Kudo Shinichi got his gender differentiation wrong.

But that didn't stop him from laughing like a dog in his heart.If it weren't for Kaitou Kidd's idol burden, Kuroba could even perform a Thomas full-spin on the spot until he hit the ground with laughter.

So he pretended to tease Kudo Shinichi who was "at a loss for the first time in heat", and then escaped from the electric well at his fastest speed, and went straight to the hall (otherwise it would be hard to say that he laughed out loud with his poker face first) , it was Kudo's pheromone that made his legs weak first).Before the person arrived, a claw had already shot to the ceiling, flying up against the eyes of the gangsters, and finally burst into a burst of hearty laughter.

——Like a real [an overbearing president alpha who hits ten times to protect his companion Omega], he has to deal with these guys happily!After that... that's right, I, Kaitou Kidd, accepted the [Kudo Shinichi's Black History of Life] as a reward for teasing a famous detective~

gunshots.The robbers' automatic pistols spit out flames, but the bullets could only touch the corner of the strange thief's clothes.Like a big snow-white bird, he swung an unpredictable long arc in the hall with incredible aerial balance.Just at the moment when the pistol ran out of bullets and needed to change the magazine, a flash bomb landed at the feet of the villains.

The arc just swings to the highest point, and the momentary state of stillness in the air, in this case, shooting at each other is not much different from shooting while standing face to face.Multiple pistols vs. poker guns. This was supposed to be a firepower suppression with no chance of winning, but because of the strong light that suddenly exploded like magic, the whole situation was reversed.

Kaito Kuroba was waiting for this opportunity—taking a huge risk, appearing in front of the gun with a loud laugh as a most conspicuous target, using his luck and reaction speed as chips, to bet on a A chance to fight back after death.

He won the bet.

Several sharp poker cards were shot out, knocking every pistol into the air with precision.The strange thief let go of his claws and landed lightly, but the robbers who still refused to admit defeat continued the style of the irritable old man, punching him without a gun, and a group of people rushed towards him screaming.Kuroba instinctively took a step back.

Tsk, the poker gun is really not powerful enough, so hypnosis gas is used here——

"boom--!"

Just as Hei Yu reached out to take out the hypnotic gas in his arms, a light cannon that was barely visible to the naked eye flew over, stacking the robbers one on top of the other, blasting them all together neatly.Hei Yu turned his head stiffly to look, and saw a football that had exhausted its kinetic energy slowly rolling down on top of the pile of small people on the ground, and even bounced on the ground twice.

Wow, this terrifying leg strength... Although I know that the alpha in the susceptible period will become super aggressive due to the omega pheromone, is this increase too much? ?

Kuroba's gaze slowly shifted to the direction the football came from.

In fact, there is no need to rely on the football to judge the position.The battle on the front line of life and death is the same as pheromone, which can make people excited. Adrenaline rushes in the blood vessels, and the sensitivity of the five senses is maximized to capture the trajectory of the bullet. When the crisis is suddenly resolved, the originally highly concentrated mind is instantly at a loss. , instinctively turned his attention to the biggest "abnormality" around——

The strong and restless alpha pheromone, despite being suppressed by its master's efforts, at this moment along with Kuroyu's still sensitive five senses, occupied his brain incomparably clearly.It may be the smell of ink, but it is a little too sharp, but it is not frightening, as if it is cold rain falling in London. Xiangli raised her head and glanced over calmly.

He was remembered and recognized by Mo Xiang.Kaitou Kidd's name was written down in black and white, and it was useless to run away. From the moment he rushed out of the electric well, that pheromone has been chasing after him like a shadow, trying to pull him into the lust.In the alpha of the susceptible period, the pheromone is also aggressive.But now, this dangerous source of pheromones is leaning against one of the walls at the entrance of the hall, with sweaty hair against his forehead, gasping for breath, with an unnatural flush on his face, only his eyes are still clear .

It was a gesture of patience that could easily be misunderstood.

Kuroba Kaito raised the corners of his lips.

Yes, his body is not normal anymore. His adjustment ability has always been very good. The rapid breathing and heartbeat caused by the battle can be recovered quickly, but now there is no calm situation at all. It is undoubtedly the influence of Kudo pheromone .But... no, he doesn't intend to escape, at least not now, the appearance of his old enemy in front of him is really too interesting, of course he has to play for a while.

Kaitou Kidd walked up to the group of bandits who fell on the ground, repaired the knife with hypnotic gas, and threw a card-like thing on top.Then he turned around with a mocking smile on his face.

"As expected of a detective, you are the first to have such impressive attack power during the estrus period. I originally wanted to deal with it before you came... It seems that being too a gentleman is not a good thing." Kidd step by step Walking towards Kudo, the scent of flowers began to spread towards the detective, with a hint of malice, "The omega induced by my pheromones is still alive and kicking, I'm quite unhappy~"

"...What stupid things... how much do you want to influence?" Kudo frowned and stared at Kidd. The desire in his body was already very anxious, and the other party actually leaned over Shi Shiran, his message Su was out of control, and enthusiastically entangled the strange thief.Kidd's footsteps stopped, Kudo heaved a sigh of relief, and then saw Kidd's chest undulating slightly, his gaze was still on Kudo, raised his hand with a half-smile, tilted his head slightly, and loosened his tie.A drop of crystal-clear sweat slid down the side of his cheek, along his neck, and disappeared into the shadow of his shirt.

Kudo's brain buzzed, his rationality was crazily calling the police, and he was afraid that he had overestimated Kidd's alpha concentration, but his instinct was crazily clamoring to go up and achieve the great harmony of life.Although I always feel that there is a sense of disobedience, but now I don't have time to think about it, Kudo couldn't help but gritted his teeth, and the hand on the wall turned white from the force: "...You guy, you don't want to do strange things, do you?" ..."

The smile on Kidd's face widened.

"strange things?"

He laughed lowly, took a step in the direction of Kudo, and then another step.The two pheromones are entangled.

"It's nothing strange... I'm just thinking about normal things." Kidd still spoke with ease, yes, exactly the same as a bad-hearted alpha who wants to tease the omega to surrender, praise is excellent acting skills, "For example, when the police department comes to support you, what should you do if you have already lost yourself due to the estrus period? There are quite a few young and vigorous alphas in the mobile team, and they don't have much willpower—I used to I tested it for you with artificial pheromone, thank me."

"Hmm—" Kudo made a distressed voice.

"For another example, wouldn't it be great if the enemy who caused me the most obstacles could disappear from the scene of my crime once and for all? Put a permanent mark on it or something..." Kidd stopped just one step away from Kudo where he bent down slightly so that his eyes were at the same level as Kudo, and looked viciously at the detective who was bending over to endure his desire, his eyes turned around and fell on his erect lower body, "Isn't it hard to endure?" Was it hard work, Detective~"

hateful--!

Kudo lowered his head in embarrassment to avoid the Phantom Thief's sight, but his attention involuntarily followed Kidd's gaze downwards, to the part that he had deliberately ignored since he realized his differentiation.Kidd was still teasing him with great interest, but Kudo's whole body froze suddenly.

"what……"

Speaking of which, from just now... Although I really want to do it, the front is so hard that it is about to explode...

But·yes·back·face·complete·full·no·has·wet·it·

“…………………………”

Kudo Shinichi raised his head slowly, with a kind smile on his face that made Kuroba Kaito creepy, it was an expression that saw through everything and added "You are already a dead person".

"Hey, Kidd, actually...you are the omega, right?"

The smile on Hei Yu's face suddenly froze, and he didn't react for a while.

"Eh, exposed?"

After being exposed the truth, he laughed three times, and then mocked you as a detective, you even got the gender wrong, did you not listen carefully to the school's physiology and hygiene class——Kaito Kuroba originally planned this, but at this moment I suddenly realized that it wasn't the time to be sarcastic. Just now I seemed to be playing too much...Damn it, I was influenced by Kudo's pheromone before I knew it!

The pheromones entangled like glue in the air, the close distance, the body that already felt dissatisfied with desire, and the alpha in the susceptible stage who exploded in front of him... It's over!Oops!Super dangerous!Although they were all made by themselves, the current situation is too bad!

I saw Kaitou Kidd's expression changing from stupefied to instant, and then a smoke bomb fell and ran away. A panicked voice came from the smoke and went straight to the window: "Since the matter has been resolved, I will excuse you first." !"

"Stop!" Kudo roared, and rushed straight into the smoke without the aid of vision, and directly followed the high concentration of floral scent to grab it.

"Farewell to the famous detective - Guwa!"

Kudo Shinichi grabbed Kaitou Kidd's wrist and pulled him to a stop.Kudo didn't think about what to do after stopping him from escaping, he just chased after him purely instinctively, with a feeling that he would never let you run away after playing with someone, and when he really caught him, Kudo was momentarily helpless. He froze in embarrassment.His palm touched a small piece of skin between the glove and the cuff of the monster thief, and the electric sensation exploded in his mind.

Both of them froze in place.

The actual physical contact time is only about two seconds, but the physical sensation is much longer. The smell of roses and ink is so strong that it seems to have a substance, and they fall from the air one by one, becoming the last straw that crushes reason.

With the last trace of clarity, Kudo Shinichi let go of his hand tremblingly.

But Kaito Kidd turned around, his eyes were lax, his cheeks were blushing, he grabbed Kudou by the collar and knocked him to the ground lightly, then kissed him fiercely.

The strings in Alpha's brain snapped, and he rolled over to put Omega under him.

The most primitive desire is like a gust of wind, blowing away reason and consciousness, and the world is empty, leaving only the person in his arms.There were hands that were inflexible but eager to untie his clothes, and the owner of the hands sprayed hot breath into his ears.

He saw the moon melt.The no longer cold moonlight flowed down, warm and viscous, turning into a puddle of water, it was rain, it was poison, it wrapped him tightly and penetrated into his bones.The rose bloomed passionately, rotted openly, layers of petals unfolded docilely, and the vines entangled themselves with possessiveness.The monster thief's legs were tightly clamped around his waist, and the pleasure exploded in the cerebral cortex like fireworks.

Now their voices don't sound the same at all, high and low whimpers and gasps, full of lust.They demanded each other fiercely, like thirsty travelers in the desert, the white cloaks under their bodies were in a mess.The strange thief's top hat was tilted on his face, a layer of fog formed on the monocle, and tears were in the other eye, which slid down the eye socket trembling under the pressure of pleasure.

Not enough... not enough...

Kudo left hickeys and scents, wedged his own existence again and again.Mo Xiang criss-crossed the body below her, from the inside to the outside, stroke by stroke, over and over again, writing the same words——

"you are mine".

In this way, the alpha's instinctive possessiveness was frantically carved on his skin.

So, can you get him?Can you catch him?The brain is muddled, unable to think well at all, but intuitively knows clearly that it is futile - of course he can be caught, and he will be caught, relying on long confrontations and equal collisions, relying on justice, wisdom and more and more A close soul, not on pheromones, or a sex that wouldn't happen if either of the partners was awake.

Perhaps it was precisely because of this awareness that his pheromones were so stubborn and angrily trying to leave traces on the opponent.

Kuroba Kaito's rationality returned a little bit in the middle of the journey—the degree of "ah, bad, I can't hold it."—after all, it was Kudo Shinichi who was in the susceptible period. , he was only affected by the high concentration of pheromone and lost control for a while.

Kudo's head rubbed against his neck, and his breath landed on the glands in the back of his neck.Black Feather moaned and raised the opponent's head, and brought it to his own lips.The out-of-control Mr. Alpha exudes frantic pheromones, but unexpectedly accepts this substitute docilely.

They climbed to the climax together.

When the spot of light in front of him dissipated and his sanity finally came back, there was no one beside Kudo Shinichi.He stood up while arranging his clothes, and looked out from the side window, a white hang glider was gradually disappearing into the night sky.The sound of Nakamori Police Department slamming the door came from the door of the jewelry store.

"Hey, Kudo-kun, are you inside! Damn, this shutter is stuck strangely—!"

Kudo's eyebrows furrowed, a little dazed.

Sex in the alpha sensitive period is very cool.Yes, it’s so cool that the memory will become ambiguous. Except for the continuous explosion of fireworks on the cerebral cortex, other memories will become blurred, because the brain does not have extra CPU to record those.

So... I was differentiated by Kidd, and I was teased by pretending to be alpha. He knocked me down after he played off. his face...

...What are these things?

Kudo Shinichi had a headache.Kudo Shinichi thought quietly.

The Nakamori police department had given up on smashing the door by itself, and his order came from outside the door, as if he planned to let the mobile team use violence to remove the rolling gate.Kudo smelled the pheromone still mixed together in the air, sighed, and raised his voice to stop him: "Police, the situation in the store has been brought under control, and Kidd escaped from the window. I'm fine here, you go and chase Kidd first." Germany!"

——And, after being tricked completely, he helped the other party hide the information about the second gender.

Speaking of which, alpha will have a psychological protective desire for its own omega... Tsk, pheromones are really troublesome, it shouldn't last long, right? This kind of influence...

Such a slandering Mr. Detective opened all the windows for ventilation with half-moon eyes, selectively forgetting the fact that they did not mark.
