I'm honestly on the verge of showing my favorite three videos to Wattpad... Edited together out of the best MK crack scenes.

Kudo Shinichi waltzed into the ballroom, a new blue suit accompanying him. With a sharp gaze, he eyed the guests.
...anyone of them could be KID.

The detective chose a corner to sit in and observe, like a predator watching put for his prey. Music lifted his spirits, it was a gentle waltz he knew from his father and the rich scent of appetizers filled the air. Sadly, Shinichi wasn't here to enjoy himself... as much as he would have liked to ditch the phantom and allow himself to relax outside Ran's and Sonoko's claws.
Some of the males were too short to be KID, he could already see that. His sapphire eyes moved guest over guest. Some women were too slim for KID, he crossed those from the list of candidates. A few men had tall, broad figures and Shinichi found himself staring them all over.
Perhaps KID was one of them?

It wasn't until a woman caught his eyes. Silky dark brown hair settling around naked shoulders, a blue dress which complimented her hibs and waist (Shinichi had yet to wonder how KID could make his hibs look this round and perfect), open at the back with a collar holding it almost glued against her perfect body. Shinichi scanned her to see wether the dress would fall in a weird manner, for weird proportions of the latex and didn't find any.
The collar hid just perfect the Adam's Apple of said sneaky phantom. Fingers always moving; Shinichi observed her for a few minutes. The hands of someone who couldn't hold them still, someone who could use them as the most dangerous weapon mankind had to offer. But he needed a last proof.
"Hm..." he voiced quietly, eyes dropping again to her hand. A... ring. With a clover charm on top of it. It was weird enough to see her wearing those black satin gloves reaching towards her ellbow, his eyes catching a ring on said ones wasn't much of a surprise.
Currently, KID was being hit on by one of the guests... his body language was open, but closed off immediately as the man inched into his personal space, signalyzing his disinterest. The man, however, didn't seem to notice and continued his plump flirting. As amusing as it was to watch KID trying to weasle his way out of the obviously uncomfortable conversation, the Beikan detective felt himself obligated to lend him a hand.

Decision made, he took two glasses of wine and approached the pair.
"Where have you been?" he addressed the KID and held the glass out to him, "Didn't we agree to meet each other at the entrance? I have been waiting the whole time."
KID rolled along with this pretty easy as soon as he realized his intentions and plucked the wine glass from his hand to take a sip, leaning in an appropriate yet distinctively intimate way against him.
"I'm so sorry, I must have forgotten! Please, forgive me?"
The suitor who watched this, backed off with jealousy twitching at the corner of his lips. He hastily excused himself and left.

The two immediately put a bit of distance between each other and KID chuckled, eyes flickering to meet Shinichi's.
"My knight in shining armor. But I am sure I could have managed that alone, too."
"As a gentleman I feel myself obligated to help a damsel in distress," the young detective replied with a hint of smugness in his voice, causing KID to chuckle again. The voice he used for this woman was deeper, but together with the outlooks it was down right seductive and sexy. No wonder the guy had had his eyes on him.
"A gentleman, hm?" he mused and eyed Shinichi from head to toe, "All alone? You are the youngest I have seen so far on this party."
The male cocked his head to the side and his answer went just as smooth from his lips.
"I am not here as a guest, much to my dismay. I am here because of the KID heist... Kudo Shinichi, highschool detective," he formally introduced himself and the masked KID allowed himself a tiny whistle.
"Highschool detective? So young and already a man of career? My name is Sumiye Toki."
"A pleasure to meet you. Well, it was gifted, in a way. My father is a mystery writer and occasionally helps out as a detective while my mother is a famous actress. I nearly run every second day into a crime but it doesn't take too long to solve them."
KID whistled again, bending slightly forward into his personal space which Shinichi immediately noticed. The heart shaped hole gave now a very interesting view onto his cleavage; Shinichi would have blushed if he didn't know it was fake.
"So a gentleman, famous detective, rich and also good looking~ Is there something you aren't perfect at?" he playfully cooed and Shinichi swallowed down the tiny lump starting to form within his throat.

Did KID... flirt with him?

"Well, Sumiye-san..." he mused, flushing a little sheepish as he formulated a reply, "I am a great failure considering cooking. But it wasn't necessary to learn it, as I don't have the time to cook, either."
During the conversation, he thought about the name KID had chosen. Another hint towards his secret identity. Sumiye meant intelligence, Toki opportunity. A good name for a genius phantom.
The time of the heist inched closer and Shinichi noted with pleasure how KID's shoulders tensed for a split second as he got a look at the clock.
"Say, oh great detective, what can you tell about me~?" she purred and Shinichi quirked an eyebrow. It wasn't like him to show off his skills but KID was almost begging to be unmasked. A dare, perhaps? Shinichi wouldn't let his challenge slip.
"Well," he began, circling him. KID tried to move with him but Shinichi had a good hold on his shoulders, preventing him from doing so. He could imagine the thief didn't like facing his back to him and Shinichi was having a great time pissing him off.
Time to return the favor.

He grasped KID's hand and lifted it, pressing a gentle kiss on its back.
"Your hands are your most important weapons. Skilled, slender... trained, in a way. You are also quite athletic..."
Proving his point, Shinichi dipped his finger gently between his shoulderblades and savored the tiny hitch KID's breath made.
"I wouldn't be surprised to see you walking on your hands."
His finger slipped slowly lower and Shinichi watched KID's muscles flex below it. He had done a good job, covering all these scars with makeup, but KID couldn't betray Shinichi's touch.
"You are a gymnastics enthusiast, aren't you?" he purred flirtingly into KID's ear, well aware his own chest pressed gently into KID's bare back.
"Y-yes. I'm impressed~"
It wasn't a lie, after all. But that tiny slip up made Shinichi curious; he released his tiny trap and returned to his place in front of KID.

KID blushed.

Shinichi would have doubled over laughing but it would have ruined their silent battle of wits. Despite that, it sure was a victory to see the KID blushing under those layers of makeup.
"Milady, are you feeling unwell? Your cheeks are a little red~" he teased with his best innocent voice and swore to see KID glaring at him for that.
"Ah, of course I feel alright. But I do have an unfortunate appointment I have to attend now..."
Was he trying to back out? Shinichi chose to poke further.
"No goodbye kiss?" he mused, fake disappointment wavering in his tone. KID froze and shot him a calculating look which he returned, challenge blooming within his eyes. KID wouldn't back from a challenge.
"It's fine it's fine, I was jo-" he cut himself off by finding KID just inches away from his lips, eyes staring deep into his own.

KID challenged him. Challenged him to kiss him. Shinichi wasn't sure why KID wanted this, to just pop out as KID afterwards and laugh at him for flirting with him? No, not like that.
Shinichi closed the last bit of gap and the thief in disguise melted against him. He could taste the thin layer of makeup on KID's lips. Were they even his? He didn't remember KID's lips to be so full, so... juicy?
What was he thinking?
KID pulled away, pink tongue darting over his lips to wet them again. Lights turned off and on again, and just as expected, Sumiye-san had vanished into thin air and KID stood on the stage.

A long and exhausting chase later, Shinichi left the manor, yawning. A shadow closeby automatical froze him into alarm until he heard the unmistakeable voice.
"You knew from the beginning, didn't you?"
Shinichi untensed and smirked, slowly taking step by step towards the luring darkness.
"Of course. You nearly screamed to be unmasked. I had to search for a person with anything covering their neck. The gloves gave away a lot, too. Just as the ring. Your slightly broad back muscles, your legs. Let me just ask one question... How did you manage to attach the latex of a chest without anything showing on your back?"
KID chuckled and leaned against the tree next to him.
"A magician shall never tell. Why did you decide to kiss me?"

"I... I honestly don't know. I expected you to back out, I think."
KID rolled his eyes in a playful manner but before he could answer, Shinichi added "Yes yes I know it was dumb to expect Kaitou KID denying a challenge."
"I'm glad you realize this. So..."
Both stared at each other, Shinichi finally stopping in front of the thief. Thr atmosphere became awkward until KID shot a smirk at him.
"Want to taste the real thing~?"
"Are you hitting on me?" Shinichi asked with a baffled look and the magician nodded.
"Yes, dense idiot."
"Let's see if you won't regret that," Shinichi replied with a lowered voice and cornered KID against the tree to capture his lips in a far deeper kiss than before.

A moan of delight was audible from his companion as the detective nibbled on his lower lip. Why did he make out with a thief again?
Oh right.
Shinichi loved him.
