Author's Note: Hello all :) This is more of a disclaimer. I am rusty to writing, and I will be practicing again and posting more stuff. My Gotcha! got a lot of good views and some nice reviews. So I'm thinkin maybe I should post some more dirty stuff with our favorite twins, but w/ plot eh? So that means chapters. & yes, that means no good bits in the first chapters haha! Anyways, enjoy the read yeah?

Rin Kagamine was maturing, and Len did not like it.

He watched the process happen slowly. He was always amazed how the female transformation construed. His cute little sister who played with stuffed animals and watched dumb cartoons with, is now wearing shorter skirts than usual, and putting her hair up in weird hairstyles he's never seen, and worse of all, the makeup.

But the most noticeable change was her body. Their bodies used to be similar, Len and Rin. They both had long, slender bodies with petite limbs. They looked so identical they'd switch clothes and pretend to be each other. But that was in the past.. Now. Well, femininity had finally approached Rin with kindness. Rin's straight, rectangular figure… well, fleshed out and she began to have more of a curvature body. Len first noticed when they were snuggled on the couch, and she hugged him tight. He felt her bosom press against him… and that was the thing. She HAD a bosom. Not her flat chest.

Len just didn't like it. And he surely didn't like how it made him feel towards her.

It was early in the morning, and Len had just finished getting dressed and was coming downstairs for breakfast. What met his eyes was shocking. His twin was sitting at the table with the makeup of a model, painted nails, and braided hair. She played with the school uniform; she added belts and wore bright colored knee-highs with wedges, lowered the top so that she showed a bit of cleavage. She looked much, much older than she was, merely 16.

Len glowered at her and set his bag down on the table. She looked up at him, her brows furrowed. "What?"

He visibly looked her up and down and gestured towards her outfit with an open palm. "What the hell is this?"

Rin looked down at her outfit and stuck out her chest a bit. "My clothes? Don't I look super cute?" She giggled as she stuck a piece of toast in her mouth.

"Y-you," Len stammered, unable to find the right words. He looked at her and pierced his lips. He had to stop himself from looking at the line of her chest that peeked out of her top. "You can't go like that."

She looked at him with a raised brow, and swallowed. "Why not?"

"You just can't. I won't allow it." Why didn't she understand? If she went to school like that, and knowing how the guys are at their school, she'd surely have a LOT of unwanted attention. And that is exactly what Len was afraid of.

"Excuse me? I can wear whatever I want. You don't control me, okay? Leave me alone." With that, Rin hopped up from the table and exited the door, her bag slung over her shoulder. Len went after her, and they walked to school, with Len at a distance.

Len's fears were definitely confirmed. Boys ogled at his sister and nudged their friends to look as his sister walked the halls in her short uniform skirt and revealed her shapely legs. It was like she was completely oblivious with how low her top went when she bent over, or how her yellow striped panties were visible if she bent over far enough. Len made sure to shoot the male students a glare before they could even think about looking at her. As for Rin, she didn't really notice the attention except from her friends, who showered her with compliments with how good she looked.

Encouragement she does not need, Len thought bitterly.

Unfortunately Len couldn't be glued to his twins side forever, and had to part from her so he could go to his Chemistry class. He struggled to focus to the teachers lecture however, too distracted by mental battles going on his head.

Why was he feeling so… protective towards Rin now? Was protective the right word? Maybe not. He buried his face in his palms and exhaled. Usually he didn't care what she wore, because she was a petite, annoying little brat who bugged him a lot and wore her bow on top of her head like always. She was never 'sexy' or 'womanly' in his eyes. And now, well now, she's quite different. Voluptuous. A word Len would have never associated with his twin.

Next thing Len knew it was nearing the end of the day, and he was exhausted from trying to be Rin's fuckboy shield, and was going to meet up with his twin at the gate so they could walk home. He was walking with Kaito, his best friend. They talked about finals, and other regular topics until Kaito stopped and cleared his throat.

"You know, about your sister…" Kaito started, a frown spreading on his lips.

"...What about my sister?" Len scowled at the blue-haired boy. Kaito knows that they had an unspoken code about him speaking with Rin, they were best friends. Don't date each others sisters. He would kill Kaito.

"Well, lets say she… has an admirer. Whom she happens to admire back," and as they both were nearing the gate, Kaito stepped in front of Len to prevent him from going further. "A lot."

"Kaito, what the hell?"

Kaito clasped his hands together pleadingly. "Don't get mad, okay? Just breathe and think about how your sister is mature now and-"

Len moved Kaito out of the way, and what he saw at the gate yards away stopped him in his tracks. His cerulean eyes widened.

Rin was with a male student, clearly a senior, with a deep purple ponytail and a stupid smirk on his face. He had his hands on her hips and pressed her against him. His twin was dumbstruck in infatuation, and was giggling and blushing at his exploring hands.

Only one senior had that stupid eggplant color of hair. Gakupo.
