[Semi-Twinning, Sluttification]

Everyone had their secrets. No matter how small. No matter how humiliating. And in the case of a young man by the name of Ken, who built himself up to be a rather repressive individual due to the way he tried to avoid getting chummy with anybody, of course he had a secret.

That secret wasn’t how much he wanted to be friends with people. You could tell that by the way he huffed every time the topic came up. No, the secret was much simpler, and it revolved around the item he was expecting today. An item that he had been waiting for, ever since he saw it online. And today was going to be the day.

“It better be here soon. Don’t want Mom to find out about this…” The black-haired youth muttered to himself as he paced back and forth inside his living room. It wasn’t often that he got to spend time all alone like this, but he cherished the opportunity. Especially since it mean that his mom, who cared way too much about him, wasn’t around to tease him for his choice in fashion, or the way he otherwise acted towards others.

Just as he started ruminating on the way he treated others, he heard the doorbell ring. Finally. It had taken so much damned time that he honestly thought about just going off to sleep. Seriously, the sun was about to set… which also probably meant that his mom was out playing with dad again. How did those two end up so ‘active’ despite being in a loving relationship, he never bothered finding out. He just knew it bothered him.

Ken headed straight for the front door, practically throwing it open as he was ready to greet the delivery guy. The less time he spent talking with them about the contents of his delivery the better…

“Hey Ken! You’re not out on a run of your own? Did you slack off today?”

And immediately, the boy’s expression soured as he saw a certain pink-haired boy at his doorstep. “No, Albert, I had the day off.” The grumpy boy said as he reached out towards the box in the feminine boy’s hands. “Please just give me my delivery, and go.”

“Huh. You don’t usually take days off, so this has to be a really important thing.” The pink haired-boy, Albert Grimwald, smiled as he handed the box to him. “But, uh, this was my last stop. Your place is at the back end of the neighborhood, so I wanted to drop yours off last. And besides, it means we can hang out!”

Ken wanted to find an excuse to make him go away. He really did. But at the same time, that boy’s infectiously happy smile was too hard to ignore. It broke through even the edgiest of hearts, prompting the black-haired boy to just take his package and leave the door open. “Suit yourself. Mom’s not going to be home until the moon comes up, and even then I’m not sure if she’ll show up.”

“Okaaaaaay!” Albert chimed as he jumped on into the house, before quietly turning around to close the door behind him. Always a polite boy.

The black-haired youth took a seat on one of the couches as he carefully put the box on the table, watching his ‘friend’ take a seat on the opposing couch. “Can’t believe you had to show up now of all days. Isn’t your sister supposed to be stopping you from working, with how much she ‘loves’ you?”

“Alice’s busy with her friends! She said something about beating them in a race, and she had done a lot of training lately. I’m so proud of her, I remember when I had to care for her, but now she’s all strong and fast and cute! Any big brother would be proud of a girl like that!” The pink-haired youth rambled and rambled, practically making the edgier boy’s ear fall off from the praise he piled on his non-present sister.

Ken rolled his eyes. “If you love her so much, why don’t you marry her?” He muttered as he flipped out a knife from his pocket. He didn’t actually use it for anything violent, but it completed his look. Nobody would mess with a guy with a knife after all.

“I can’t do that, she’s got to find love for herself! And I’m sure there’s plenty of good people out there that want to love her!” Albert giggled, watching his friend undo the tapes that kept the box shut. “So, uhhhh… What’d you order?” He finally popped the question, tilting his head slightly.

The edgy boy didn’t answer verbally, preferring to just open up the box and let the contents speak for themselves. And they certainly did, as a twin-tailed cyan hat-styled wig landed on the table. It was way too easy to tell what it was, which was probably why he tried to stay so secretive about it all.

“A Miku hat? I didn’t know you were into digital idols, Ken! Do you want me to try and get one made for you? I’m sure Mom can find a way to get you digitized!” The pink-haired boy, definitely rich considering how lackadaisy he was, already got distracted despite seeing the evidence.

Ken reached across the table and lightly ponked the femboy on the head. “No, I don’t want that. My mom’ll find out and she’ll tease me harder.” He said plain and simply as he grabbed the hat off the table. “I just wanted to try and see what would happen if I tried to look like her. And… well, maybe I’ll sing. But only once. Got it?”

“Got it! Just sing when you want to!” Albert giggled as he got nice and comfy on the couch, waiting patiently for the edgy boy to wear his new hat. And to see how it’d fit him too. He really didn’t know what to expect… Besides Ken being cute. That was a given, whenever he tried to crossdress.

The edgy boy just shook his head as he grabbed the hat and got up, walking over to the same mirror his mom always used. Just looking at himself, he seemed like a strapping young lad buried underneath a layer of really edgy stuff. Black and red clothes that were partly torn, with his pants suffering the worst of that treatment. Combine that with a near-permanent scowl and he looked like a wreck.

But stripping all of that away, he was a fit boy due to his job. Being a delivery boy meant going all around the town, and making sure that you carry everything. Since he didn’t have a license, and he definitely didn’t have the time to bike well with the stuff he had to carry, he usually did it all by hand. Which meant that his body was toned beyond belief.

“You better not say anything embarrassing, Albert!” Ken shouted preemptively at his friend, before putting the hat on. Finally. Was his tsundere act a way of pussyfooting around the simple action of putting a hat on? Probably, considering the way he usually acted.

The second he put it on, he felt a jolt pour up his body. Of course something had to be wrong with this hat. Why did he even think that he could just… Buy a cosplay object for like a couple dollars, and it wasn’t cursed in some way?! What an idiot he was!

“Keeeen? Are you okay? You’re just kinda standing still.” The feminine boy said, getting up as he approached the boy from the back. Not at all paying attention to the way that his pants were quickly growing tighter, and the feminine moans leaving the youth’s lips…

The edgy boy giggled as the twintails from his hat seemed to fuse together with his hair, quickly making the rest of his black hair take on the same cyan color. It wasn’t just his hair either, the rest of his body seemed to adjust to his headgear becoming a part of his body.

How? Why, since Miku was a digital idol, it only made sense that she wore clothes that showed off her body. And since Ken wasn’t a showoff in the slightest, the hat had to compensate.

His silly shirt and his pants quickly disappeared and were replaced with a loose sleeveless vest that really brought emphasis to his smooth armpits, and a skirt that hid very little. To the point where his naked derriere was sticking out, the only thing keeping his modesty being the panties that quickly appeared on his body moments later.

But since the boy was just that, a boy, the hat wasn’t even close to done. He might look like Miku now that he wore her outfit and he had her hair, but his body was pitiful in comparison. It needed that extra bit of oomph that really brought out the fan appeal in the most popular vocaloid.

Ken giggled and panted as he felt his body shifting. His arms grew slimmer, his tummy started to push inward until it was so thin that it almost looked like it could break if you pushed him the wrong way. His chest, though not inflated because he was still a cute boy at heart, pushed out so it looked like he had a bust. And his ass, struggling to stay contained within the striped panties adorning his cheeks, bounced out until it started to twerk all on its own.

Albert was watching the entire time, a blush covering his cheeks. “W-Well, I didn’t know a hat could do all that!” The boy shivered a little as his own pants started bulging. Gosh, if he knew this was going to happen, he would’ve brought a spare set. Then maybe he wouldn’t be ruining this pair.

The edgy boy-turned-Miku copy’s changes weren’t quite done when his ass became a constantly wobbling mess. In fact, that movement was what gave his mind the beating it needed. With his thoughts completely incapacitated by the way his body played with him, it was easy to replace them all with much happier thoughts that made him feel more Miku-y…

All those silly edgy thoughts about being alone because he didn’t like people, draining straight down into his ass. Thoughts about not liking girls or boys because they just ended up getting too clingy, disappearing and being replaced with a deep need to entertain and please. In fact, that was his entire world at this point. Being close to people and having fun with them.

Giggles left Miku-Ken’s lips as he turned towards his friend, his new twintails twirling along with him. “Heeeeey, want to have some fun with Miku?” He giggled. The look in his eyes was sparkly and happy, a complete contrast from the boy he had been just moments ago.

“I-I mean, I think I do, but I’d love to have fun with Ken instead. Is Ken still there?” Albert asked, blushing a little as the vocaloid-boy winked at him. Honestly, he was super cute. But he liked his edgy friend a lot more.

Miku-Ken licked his lips as he stepped closer, heels clicking below. “Awww, don’t you wanna have fun with Miku? Well, Miku’ll have fun with you instead, then.” He chimed, before letting a single music note leave his lips. A note tuned to such a chime that it was impossible to block out.

The pink-haired boy’s cheeks flushed as bright red as they could, as he stood perfectly still after hearing that nice note. It was… Captivating. Like he was listening to the most perfect song in the whole wide world, despite hearing nothing but a single note.

Miku-Ken giggled as he squatted down to be at eye-height with the boy’s crotch. Boys like him were so easy to charm, and while their minds were full with his echoing tone…

He could have lots of fun with the stuff down below, as his lips started drooling once the youth’s shaft slipped out of his pants. The perfect thing for Miku-Ken to play with!

By the time Ken’d snap back to normal, he’d have a new secret to keep… And a new secret to indulge in, as the slutty femboy vocaloid, Miku-Ken!
