Summery: Len and Rin Kagamine are Golden Retriever puppies that were abandoned as when they we're real young and found in an ally way by Kaito. What he doesn't know is that the twin pups are harboring a skill no normal dog should have. Only the two younger siblings find out after just a short time. But what's going to happy to the pups when the other members of the family find out?

This would be another Vocaloid fic filled with a house full of Shion's. And yes I am using fan made and Kaito based vocaloid, and I couldn't find a thing about them so if anything is wrong like age and personality and stuff like that feel free to tell me please!

Now that that's over with…lets' get to the story!

"Why Rin-chan? Why did steal it from me?" a small golden blonde puppy whimpered at the loss of the small bone shaped treat. "You were to slow to eat, that's why. You spend way too much time ogling that human ya know?" Rin cackled evil licking her lips. "I…I wasn't though!" he yelled. "Were too! I saw the way you were watching that thing! You always say how much you love the sapphire blue hair and jewel like eyes." The puppy cooed, teasing her little brother.

"B…but I…t…that's because um…t…their really p…pretty…" he whined burying his face in his tiny paws. "Uh-huh, that's what that all say. You're falling for a human! You're falling for a human!" Rin chanted loudly jumping off the bed. "I did not!" Len yelled, his furry cheeks heating up as he jumped after his sister to get her to stop.

"You can't lie to me Lenny!" she giggled. "You're still in love with a human!" she squealed as Len nipped her tail making her go into a fit of hysterics. "I'm not! Please be quiet Rin-chan, Kaiko-chan and Nigaito-kun will hear you!" he panted trying to pick up speed. "It's not like their going to-Gah Feet!" Rin screamed quickly curving to the right to avoid them. "Fee-mph!" Len ran into some ones foot. The yellow puppy fell back on his butt, skidding back a few inches. His ears fell and a whimper escaped his throat.

"Hm?" The owner of the feet looked down at the small golden puppy, a light laugh reaching his ears. "It's Rin-chan isn't it?" a light voice asked. Len looked up and nodded seeing a short green person. "I figured as much when I saw her running and you chasing her. Was it about nii-chan again?" he asked. "Hai." Len barked weakly thankful for his fur. "I see. I knew it was something like that." He sighed kneeling down in front of the embarrassed puppy.

"Well, maybe I can convince Kaiko-chan to get her to stop. Len's ears perked up before falling quickly. "But she won't! If anything she'll make it worse by telling Rin to make it worse and say more embarrassing things that'll do weird things to me cause I'll start using my imagination, and…and…and they can't team up!" Len exclaimed ending with an off pitch and cracking howl. "Yeah, you have a point I guess. Then I guess you just have to deal with it and if it get's too bad you know you can come to me." Nigaito smiled.

Len blinked a few times before jumping onto his lap and licking at his face. "Naito-kun is so nice!" he barked happily making the green haired Shion giggle. "Only to Len-kun and friends." He smiled patting the small puppy between his ears. "Is that including Rin-chan? Cause she's an evil little she dog."Len said looking up at the green headed vocaloid. "Well I guess I guess it does. Her and Kaiko get along too well so I'm not really sure…they both kinda scare me." He muttered. Len giggled nudging his arm with his nose getting the boys attention.

"Oh…I was starting to mutter again…sorry Len-kun." He smiled. "Don't worry about it my fellow space case. It's only a sign that you're brain has gone mad." Nigaito giggled. "Yes I suppose you're right. But I'm not quiet sure that's a good thing though. Ah, hey Len-kun why don't you come with me?" he asked suddenly remembering what he was doing. "Where?"He barked cocking his head to the side. "I was on my way to take a walk since Kaito-nii and Akaito-nii we're fighting again. And Taito-nii and Kikaito-nee* are watching and betting over who will cave first and Kaiko and Ren are probably scheming like always." He said listing things off on his fingers.

"Okay! When are you leaving? Do I really have to wear that evil thing? I promise I won't run away!" Len was running around the green haired boy hyperly, his tail wagging like crazy the whole time. Nigaito giggled standing up. We're leaving now, no you don't and I want you to go the other way. I already have the things needed to cover those up." He said smiling. The yellow puppy howled happily running to the door before the green boy could move. "Such a puppy." He shook his head walking over to the door, missing the two figures hiding around the corner.

"Is this going to work?" the smaller one asked. "Of course it is, and I don't think he'll hate it either. It's not like he knows that he's a shotacon." The taller one giggled, watching their brother's walk out of the house.

Okay the evil little plot bunnies have attacked again and have interrupted my brain from having any ideas for my other fics sorry peoples! Comment if you want me to continue this or not…I might anyways though…but I want to know if people will read it. Arigatou Minna! Ja!

I'm not sure if Kamaito is a Nee-chan or Nii-chan…I can't remember where I found the info…:3 I'm such a fail.
