Perfectly Unplanned

[Nature of Love series]

Part 2

Something was up. Of that much, at least, Shinichi was sure. What he couldn't say was what that something was.

Shinichi had ducked into a conflict resolution panel because it sounded useful, but he couldn't concentrate.

It was that constant sense of being watched. Yet he felt no danger. If anything, the heat of that gaze was making Shinichi's body and senses alike tingle as some deeper instinct responded. It wasn't fear. It was—excitement. Anticipation. Delight.

And that meant only one thing.

The person stalking him had to be Kaito.

The realization had Shinichi taking a moment to turn his attention inward. Kaito's presence was there as it always was now that he and the magician were bonded. It was warm and strong and vibrant, and it made Shinichi smile despite himself.

That wonderful sense of connection aside, however, he could also tell that Kaito was indeed nearby. And he was purposefully obfuscating his end of their link (something the thief had proven frustratingly good at to neither of their surprise).

Shinichi, however, was a detective—and a good one at that. And now he knew what he was looking for.

A quick jaunt down a handful of corridors and brief visits to two more panels later, Shinichi had identified his stalker. It was a tall, clearly athletic man apparently in his late twenties wearing a rather eye-catching tie patterned after magpies. He also happened to be wearing a conference nametag, though Shinichi hadn't been able to get a good enough look at it to read his name. Still, the nametag meant that Kaito was actually a registered conference attendee (or at least that he'd gotten his hands on the nametag of someone who was. This was Kaito after all. Shinichi wouldn't put it past the thief to have snitched someone else's nametag if it suited him). That begged the question: had Kaito known all along that Shinichi would be here? The omega had been very careful not to let his plan to attend the conference slip (it would have been too embarrassing).

Kaito was supposed to be preparing and giving a series of magic shows in this area though, so it was also possible he'd just happened to be passing by.

But…in disguise?

Shinichi found himself opening up the conference program again to check if there was some kind of jewelry display hidden amidst the offerings. That or a speaker who might have a penchant for big diamonds. Neither appeared to be the case.

Well, he could speculate all he wanted, but there was a much simpler way to get his answers.

Go to the source.

Making sure to behave like he was still simply enjoying the conference, Shinichi made his unhurried way through the building until he located one of the elevator banks. Once there, he spent some more time perusing the program to give Kaito time to drift closer then used his body to hide the call buttons as he chose one so that the thief wouldn't know if he was planning to go up or down. He wasn't entirely sure if Kaito would take the bait, but he'd noticed the magician growing bolder in his tailing over the last hour. Besides, there were several floors in both directions that Shinichi could be headed to—including back to the floor where he was rooming, which would presumably be a mystery to his stalker. It was for that reason that Shinichi had chosen to go up.

As the detective had hoped, Kaito followed him onto the crowded elevator rather than risk losing track of him.

Shinichi was still debating between three possible next steps when fate decided it for him.

By pure chance, the last of the other elevator passengers got off at the next stop and no one got on, meaning that Shinichi and Kaito were the last to disembark. Taking the opportunity he'd been presented with, Shinichi interposed himself between his stalker and the door and hit the close button. Then he turned and leveled the disguised thief with a flat stare as the door rumbled shut behind him.

"I know that's you, Kai," he said bluntly.

"Oh?" The disguised thief raised an eyebrow then smirked. Having expected Kaito to make at least a token attempt to pretend he was a stranger, Shinichi was startled when the taller man instead stepped forward and into Shinichi's personal space. "If you wanted to be alone with me, all you had to do was ask."

Shinichi's next comment stuttered and died on his tongue as a blush rose in his cheeks. He became abruptly and acutely aware of the warmth radiating from the thief's body and the way the thief's hands had found their way to his hips.

"That's not…! I…! What…!" he stammered, taken off guard by the sudden turn of events.

"Are you feeling alright?" the thief asked in faux concern as he dipped his head to press their foreheads together, bumping Shinichi's hat up and nearly knocking it right off his head. "You look a little flushed."

Shinichi only grew redder. He could see the glimmer of amusement in Kaito's eyes despite the color contacts hiding their true color though, and it helped him pull his thoughts back on track.

Unfortunately, the elevator had already reached its next destination. The ping announcing their arrival and the rumble of the doors beginning to open sent a jolt of panic through the detective. This was not a position he wanted to be seen in while in public!

Fortunately—or unfortunately—Kaito reacted quickly.

"I'll help you back to your room," the disguised thief said as though continuing a conversation while he maneuvered them both out of the way of those coming through the now fully open elevator doors. Then he slid an arm around Shinichi's waist in a manner that probably looked like he was offering support to someone who was feeling unwell (the truth was very different).

Finding himself suddenly pressed right up against Kaito's side with the magician's arm around him, keeping him there, Shinichi gulped and struggled not to look too much like a cornered doe lest it attract attention. He should say something about being fine and pull away, but his body wouldn't obey him. It wanted to stay right where it was. Or rather, it wanted to be even closer.

Oh no, Shinichi thought distantly as he felt his heart rate picking up. He recognized the sensations stirring inside him—the spreading heat, the increasing sensitivity to Kaito's presence, the growing ache deep down inside his very core…

Trying to focus on being annoyed at Kaito's stalker tendencies instead of the way his nerves were tingling from Kaito's mere proximity, Shinichi let the thief guide him off the elevator and down one of the hotel's carpeted halls into what turned out to be a very nice suite. Once the door was shut, however, he ducked quickly out of Kaito's loose hold and made a show of straightening out his clothes. Kaito took the opportunity to engage the additional locks on the door, partly out of habit (thieves and magicians alike could never be too careful) and partly because he wanted to ensure they wouldn't be interrupted. Once they'd both finished, they were left standing in the small space between the suite's kitchenette and sitting area, eyeing each other in a silent jostling to see who would speak first.

Then Shinichi's gaze found Kaito's nametag. He did a double take, stared, then seriously considered smacking himself on the forehead.

"Dr. Shirota Kidd," he read off of the nametag then leveled the 'doctor' with a very flat look. "Really?"

The disguised thief grinned, unrepentant. "Isn't it funny?"

"…To you, I'm sure it's hilarious."

"My opinion's the one that matters."

Shinichi rolled his eyes. "Of course it is. So anyway, are you going to tell me why?"

The question earned him a confused look that he didn't buy for an instant. "Why what?"

"This." Shinichi gestured at Kaito's person with no little exasperation. "All of this. There isn't a heist scheduled that I haven't been told about, is there?"

Kaito's surprise this time was genuine. "Never. You'll be the first to hear when I finish my next plan—whether that's here or somewhere else. You know I wouldn't exclude you. My heists aren't half as fun when you're not there."

Not sure if he should be flattered or exasperated (or some combination of the two), Shinichi folded his arms. "So then? Why are you here? And like that?"

Kaito shrugged. "Lots of reasons. You know I have several shows in the area this week. This just happened to be the hotel I picked. And conference sounded interesting. As I had some free time…" He shrugged.

"That doesn't explain the disguise," the detective pointed out.

"It's fun."

Shinichi did smack himself this time because he could totally see that being the reason.

"It wasn't because you knew I was here and wanted to wig me out?" he asked suspiciously.

"That was an unexpected bonus," Kaito replied without an ounce of shame.

Shinichi's eye twitched. "You're unbelievable."

"Thank you."

"That was not a compliment."

Kaito chuckled. "Come now," he said, closing the distance between them and looping his arms loosely around Shinichi's waist. "You can't pretend you aren't happy to see me."

The detective huffed. "I'd be happier if you'd told me you'd be here."

"Hey, you didn't tell me you'd be here either," Kaito pointed out.

Shinichi had nothing to say to that, mostly because it was true.

"I…was just curious," he muttered a bit lamely, looking away.

Kaito smiled softly. "As was I."

Shinichi peeked at him out of the corner of his eye. "Really? What were you curious about?"

"Oh, you know. This and that. Bonds, relationships, tips for relationships, that sort of thing."

Shinichi blinked. Then his face broke out into an answering smile. "I…sort of came for the same things."

Kaito winked. "You know what they say. Great minds think alike." Then his smile grew wicked. "Now that that's settled, let's have a look at this little problem of yours." One of his hands slid down to squeeze Shinichi's bottom.

Shinichi turned red. "Wha—what are you talking about? I don't have any problems. Anyway, if that's everything, I'm going back to the conference." He extricated himself from Kaito's grip and attempted to make a beeline for the door. He hadn't even made it two steps before Kaito caught him and reeled him back again. The next thing he knew, he had his back pressed against Kaito's chest and the magician's arms around his middle.

"Now, now, you can't fool KID-sensei," the thief admonished. "The rest of today's conference vents are invitation only, and you're clearly unwell. But as it happens, you're in luck. I learned some very interesting things today, and I know just what you need," he breathed into Shinichi's ear and smirked when he felt Shinichi shudder.

Shinichi swallowed hard as he fought not to squirm. He knew he was caught, and the realization was only making the heat inside him spread faster. His breaths were coming in shorter as his heart rate sped up again.

"Well?" Kaito prompted again, warm breath tickling the shell of Shinichi's ear. "Do you want KID-sensei to make it better?"

One of his hands slid down the length of Shinichi's body to press between his legs.

"Y—yes," Shinichi gasped, the word escaping before he could stop it, and he blushed furiously. But the hand cupping him gave a squeeze, and he mewled as he found himself leaning heavily against Kaito's chest for support.

"What was that?" the thief purred, indigo eyes gleaming like those of a hunting cat stalking towards his cornered prey.

"Yes, Sensei," Shinichi whimpered, clinging to the arm that Kaito had around his waist. The alpha's hold was the only thing keeping him on his feet.

Pleased, Kaito adjusted his hold on the panting omega and gave him a moment to steady himself. Then he gave Shinichi a gentle nudge towards the suite's bedroom door.

"Let's take this to my examination room, shall we?"

Though he knew he'd already surrendered, Shinichi felt obliged to at least grumble, "How do I let you talk me into these things?"

"Oh that's easy," the fiend in human guise known as Kaito replied with a cheerful grin that was nevertheless filled with predatory intent. "It's because yours truly is the great Kaitou KID and therefore awesome—not to mention the love of your life. And," he went on, voice dropping low as he let a hand slide down to grope Shinichi's bottom again. "Because I know just how to make my little Shin-chan feel good~."

-0-

"Now Shin-chan, I'm going to need you to take your clothes off for me," Kaito said. "Take it all off."

Shinichi's blush returned with a vengeance, both at Kaito's words and at how eager his own body was to obey. Having Kaito order him to strip was turning him on even more, and the way Kaito was watching him (like he was a particularly tasty delicacy that Kaito was planning to devour slowly and with great relish) wasn't helping (was helping? He wasn't sure anymore. Shinichi's thoughts seemed to be getting jumbled, and he found he was having trouble remembering why he'd been resisting. Why would he want to be anywhere else when his alpha was looking at him like that?).

He could feel the heat rising in his cheeks (and curling in his stomach and skittering along his nerves). His breath quickened.

"It's rude to stare, you know," he felt compelled to point out—not that he thought it would do any good.

"I'm not staring. I'm studying my patient," Kaito countered, proving him right.

For the sake of his own sanity, Shinichi turned his back to Kaito so he wouldn't be able to see the alpha's eyes. He could still feel them though. Their gaze was a tangible warmth caressing his skin as his unbuttoned shirt slid off his shoulders.

He hesitated then, trying to decide where to put the shirt, but a presence came up behind him and the article of clothing in question vanished.

"There's no need to be nervous," Kaito murmured into his ear as he began to massage the omega's tense shoulders. "Rest assured, I'm going to take very good care of you."

He couldn't resist a smirk when he saw the back of Shinichi's neck redden. It wasn't long, however, before he felt the detective begin to relax under his hands. In response, he worked his hands over Shinichi's shoulders, down his arms and back up again, paying special attention to the tight knots he found. Soon Shinichi was leaning into his touch.

"You should lie down now," Kaito decided. "But first…" His hands ghosted down Shinichi's body. A second later, the detective's pants and undergarments went sliding to the floor, leaving the omega fully exposed to Kaito's roving eyes (and hands).

The thief hummed in satisfaction. "There. Much better. Now, I'm sure you'll be more comfortable on the bed."

He snapped his fingers, causing the bedcovers to fold up to one side.

"I'd be more comfortable if you weren't so overdressed," Shinichi replied, casting a sidelong look at the thief. He did a double take. "Why are you still wearing that face?"

"Oops. Forgot about that." Kaito snapped his fingers again, and there was a puff of smoke. When it cleared, he was once again wearing his own face. He snatched Shinichi's fake glasses and hat as well, making them disappear with a flick of his wrist. "There we go."

He flashed Shinichi a grin as he shrugged off his suit jacket and tossed it over his suitcase where it rested on the luggage rack. Then he loosened his tie and dropped it on the jacket. "Better?"

"You're still overdressed," Shinichi pointed out.

Stepping closer to Kaito, he reached up and began deftly unbuttoning the magician's shirt. Letting out a soft laugh, Kaito let him finish then caught Shinichi's hands and brought them up to his lips.

"I can see there's nothing wrong with these beautiful hands. That's good," he declared before using said captured hands to tug Shinichi into a kiss.

Shinichi's mouth opened under his with a small gasp, and Kaito immediately deepened the kiss. Shinichi responded eagerly. He moaned softly, moving instinctively to press himself as close to his alpha as he could get with Kaito still holding his wrists captive. He could feel Kaito's warmth and the contours of his body through the fabric of his clothes as well as the growing bulge in his pants as it pressed against him. The sensations made Shinichi tremble with an ever more desperate need.

Shinichi's body moved of its own accord to grind itself against Kaito's clothed erection, heedless of the layer of cloth between them (if anything, the added friction only stoked the flames curling inside him).

Kaito made a noise between a groan and a laugh. Damn but his Shin-chan was absolutely irresistible (delectable? Maddeningly adorable? All of the above and then some! And Kaito really didn't know if it was better or worse that it was largely unintentional on Shinichi's part).

"I can see we have an urgent case," the self-proclaimed doctor said, voice low and husky with lust.

Shinichi only noticed that Kaito had been backing him towards the bed this entire time when he ran into it and toppled backwards onto the mattress with a squeak. Kaito was quick to follow him, pushing him further up on the bed. Then Kaito had captured his wrists again, pinning them on either side of Shinichi's head as the thief leaned down to crush their lips together in a searing kiss. The detective moaned, knees coming up on either side of Kaito's hips.

The kiss left Shinichi gasping for breath, head spinning and more aroused than ever. He wasn't given any time to recover, however, as Kaito immediately latched onto his neck, sucking and biting at the sensitive skin in a way that was sure to leave marks (a thought that had Shinichi's inner omega shuddering in delight. An answering thrum of pleasure echoed down his bond with Kaito like a mental purr).

"Well, everything seems good here," Kaito murmured into the crook of Shinichi's neck, lips curling into a smirk as the omega sighed and shifted to give him better access.

Kaito spent another minute nibbling and licking at the reddening skin before migrating down to leave more hickeys across Shinichi's collar bones and shoulders. Then he found Shinichi's right nipple and, grinning wickedly, nipped it sharply. Shinichi squeaked and bucked under him. Grin growing, Kaito switched to teasing the nipple with the tip of his tongue until it was a hard little nub of sensation.

"Seems you're quite sensitive here, hmmm?" he murmured, giving the pert little nub another teasing lick before shifting to its twin. "Let's check here too."

Shinichi made a noise that was somewhere between a moan and a stifled giggle, tugging ineffectually at his still trapped wrists as he squirmed.

"Definitely sensitive," the thief proclaimed.

"Only because you're teasing them," Shinichi complained halfheartedly.

The comment earned him a chuckle. "I'm just being thorough."

Kaito released Shinichi's wrists so that he could run his hands up and down Shinichi's sides. The detective took the opportunity to run his hands through his alpha's mess of dark hair. The thief made a low, rumbling sound in the back of his throat that was somewhere between a growl and a purr and nuzzled his face into Shinichi's soft stomach.

Then Kaito's hands were on his thighs, stroking them spreading them even wider as the magician shifted his attention lower. Shinichi's breath hitched, and his hands fisted in the sheets.

Kaito trailed hot, biting kisses over Shinichi's sensitive inner thighs.

Above him, he could hear Shinichi making breathless little mewling noises in response to Kaito's every nip and suck, and those delectable sounds were going straight to Kaito's already rock hard arousal.

Shinichi was already leaking as his body cried out for his alpha's touch. The scent and the taste of his Shin-chan was like a drug going straight to Kaito's libido.

But because he rather enjoyed making his detective squirm, Kaito only gave that, twitching little hole a quick, playful lick before returning to leaving vivid hickeys on Shinichi's thighs.

Shinichi's disappointed whine became a gasping cry as Kaito's talented mouth then moved on to the omega's erect member.

Smirking, Kaito took the omega detective's length into his mouth, teasing it with his tongue then sucking hard, enjoying the way Shinichi mewled and writhed helplessly against his hold until Kaito removed his mouth to instead trail the tip of his tongue up Shinichi's length.

Shinichi groaned, squirming against the soft mattress and the iron grip keeping his legs spread wide. His hands twisted in the sheets as though trying to hang onto a lifeline.

Kaito rose, taking a moment to simply admire his handiwork. His detective made for quite the captivating sight, splayed out beneath him all flushed, panting and helplessly aroused, ready for Kaito to take him however he pleased.

Kaito could feel his own erect member growing even harder at the thought. He had to take a moment to regain his self control. Then he shifted, letting one hand slide deliberately up Shinichi's thigh before rubbing two fingers lightly against the omega detective's entrance.

Shinichi's breath hitched, and Kaito grinned. He proceeded to trace the tight ring of muscle with his fingertips, savoring the way Shinichi quivered.

"I do believe we've found the problem right here," Kaito crooned as he pushed his fingers into the omega's slick, tight passage. He smirked as Shinichi moved instinctively to allow him in even deeper. He leaned over to brush a feather light kiss over Shinichi's parted lips. "It seems this sweet little hole of yours is hungry for attention."

Kaito crooked his fingers on the last word, pressing hard into Shinichi's sweet spot. The omega detective gasped and convulsed under him, inner muscles constricting around Kaito's fingers as a wave of slick gushed over them.

The magician let out a low, delighted chuckle. "You see? It's begging to be filled already."

Shinichi blushed and started to say something, but his words turned into a squeak as Kaito's fingers crooked again. The squeak gave way to a breathless little moan as those fingers continued to thrust and scissor.

"I recommend we begin treatment immediately," Kaito murmured into Shinichi's ear before he nipped at it. "Agreed?"

"Aren't you supposed to explain what the procedure entails?" Shinichi asked, managing a passable imitation of his usual deadpan tones.

"Ah, of course. Forgive me for the oversight," Kaito replied, eyes twinkling with delight that his detective was playing along. "First, we'll have to make sure you're properly stretched. Once you're prepared, I'm going to put my cock inside you, and then we're going to give this naughty little ass of yours a good, hard workout." Dr. KID smirked an extremely un-physician-like smirk as he felt Shinichi shudder and clench around his fingers at his words. "Ah, I see you like that idea. So shall we get started?"

In response, Shinichi turned his head and managed to catch the alpha's lips with his own.

Kaito decided that that was a definite yes and pushed a third finger into the detective.

Shinichi moaned. "Kai…!"

"Now, now," the thief crooned, twisting and scissoring his fingers against the clench of Shinichi's sensitive inner walls. "That's KID-sensei. Though just Sensei will do too."

Shinichi struggled and failed to suppress a whimper. "Sensei, p—please." His inner muscles stuttered and constricted around those devilish fingers.

Indigo eyes gleamed. "As you wish."

He removed his fingers, and Shinichi had to swallow a whine at the sudden emptiness. He heard the distinctive sound of a zipper and the rustle of sliding fabric. Then he felt Kaito at his entrance, and his breath hitched in anticipation.

Hands gripping the omega detective's hips firmly, Kaito entered him in one excruciatingly slow, deep thrust.

Shinichi moaned breathlessly as his alpha filled him inch by hot, hard inch. His inner muscles stretched, stuttered and clenched as that large cock plunged deeper and deeper into him. Then Kaito was finally fully sheathed inside him, and Shinichi could only whimper. A shudder of pleasure ran up his spine, and he nearly came right then and there.

Kaito stilled, savoring the sensation of being hilt deep in his detective and drinking in the expression of intense pleasure on Shinichi's face.

Kaito shifted. The movement caused his length to rub against his omega's sensitive inner walls, and Shinichi mewled.

The sound went straight to Kaito's erection, and he discovered that it was in fact possible for him to grow even more aroused.

His grip on Shinichi's hips tightened as he pulled almost all the way out of the omega then thrust all the way back in. Then again. In, out, in—a firm, deliberate rhythm.

He was determined to ensure that Shinichi felt every inch of his desire as Kaito thrust deep into his core again and again and again.

Shinichi was panting hard now between little gasping cries. He felt as though his entire body was one great, quivering puddle of raw sensation—of pleasure and want and desperate need.

Another deep thrust, and Shinichi came with a cry.

The feel of his omega's slick, velvet heat tightening around him had Kaito's inner alpha surging forward with a ravenous snarl. His thrusts became faster, harder. Again and again, Kaito drove himself deep into that delectable heat and reveled in the way Shinichi positively writhed under him.

It wasn't long before Shinichi was fully aroused again and riding Kaito's thrusts with a wanton enthusiasm that had his alpha completely enthralled.

Knowing that he was about to reach the edge, Kaito's grip on Shinichi's hips tightened. With one last thrust, he pushed himself as deep into Shinichi as he could get and came hard.

The sensation of his alpha coming deep inside him had Shinichi coming as well. His inner walls stuttered and constricted, eager for every drop of his alpha's seed.

Kaito made a noise that was somewhere between a groan of pleasure and a hum of approval.

"Very good," he murmured against Shinichi's lips as he gave a last few shallow thrusts. "I think we can call this first treatment a success."

Shinichi shuddered, moaning softly. "Yes Sensei."

It was Kaito's turn to shudder. "You know," he murmured. "I do believe I'm going to have to arrange us some alone time in a classroom one of these days."

Shinichi processed that then blushed crimson. "I'm going to pretend I didn't hear that."

Kaito chuckled and kissed Shinichi again.

They lay entwined for several comfortable minutes, simply basking in the closeness, until Kaito's phone buzzed.

"What's that?" Shinichi asked a bit drowsily. "Text message?"

"No. It should be a reminder," Kaito murmured back. "I have a dinner reservation in an hour. I set it to remind myself to get back here and change."

Shinichi made a mildly disappointed noise. "Does that mean you have to leave?"

Kaito chuckled, nuzzling into Shinichi's neck. "Not unless you want me to. I'll call and tell them I'm bringing a guest. Or I can cancel the reservation and call for room service if you'd prefer."

Shinichi gave it some thought then sighed. "We may as well see if you can add me to your reservation. Canceling last minute when you don't have a good reason would be rude, and I promised Ran I'd eat a proper dinner anyway."

"Gotcha. Just let me make that call. Then we should probably take a shower."

They untangled themselves with some reluctance, and Shinichi watched as his alpha rolled off the bed and onto his feet. Secretly, he found the sight of Kaito all rumpled with both his shirt and his fly hanging open, trying to shed his clothes without tripping while simultaneously rummaging through his discarded jacket for his phone rather funny (and kind of thrilling in a way he needed to stop thinking about if he didn't want his body to start reacting). Then Kaito's shirt landed on the end of the bed followed by his pants, and Shinichi turned to hide his blush in the pillows.

His alpha was very hot.

"Like what you see?" Kaito teased.

"Don't say things like that while you're on the phone!" Shinichi hissed, mortified.

"Relax. No one's picked up yet. Oh, hi, I'm calling regarding a reservation I made for later tonight."
