Finally attempting to update this one after a while, sorry about that guys. Just a major case of writers block…-.- Anyways here's chapter 4. Hope ya people like it. OH and yet again I DON'T own vocaloid.

"It worked so better than I thought it would! Ted-kun, move this one and set the little one up here for me." She giggled like mad going back to her table and filling up another potion for Len. "Alright little sister, I have the girl tied up so she won't interrupt you and the puppy is so scared he won't move." Ted smiled with a small laugh. "Good, now hold still o-chibi, this will only hurt for a few minutes" the dark haired pinkette giggled.

"N…no please! Rin-chan please help me I don't want that!" the blonde puppy started whimpering and looking up at his now human sister with begging bright blue eyes. "Let him go you witch! Lenny run don't let them inject you with that!" the now blonde girl snarled trying to break out from the binds around her. "Ted-kun, if you will please hold her still for me while I give this puppy the serum." The long haired male grinned with a nod. "No Lenny!" Rin screamed as the pinkette injected the little blonde making him yelp and whimper before soon passing out.

*present*

"No way!" Kaiko exclaimed with wide eyes shooting up from the bed they were now sitting on. "Yeah… she made her brother hold me down while they injected Lenny with the stuff. She didn't know that not only would it have the same effect that it had on me but it had an extra one too…" Rin said seriously playing with the sheets. Kaiko sat back down waiting for her to say more.

*past*

"No Len please wake up!" she screamed struggling harder in the binds and the boys grasp. "Oh don't worry little girl, he'll wake up eventually. And while he's sleeping I'm going to draw a little bit of blood so I can exam all that it did to you exactly." She grinned pulling needle from the table closest to her flicking the tip making Rin cringe at the sight and freeze up. "This will only sting little puppy don't worry." She grinned forcefully grabbing a hold of the girls arm tightly making her growl, practically stabbing the needle in her arm drawing blood. "There we go. Now how about we get the little one while he's still passed out?" she giggled setting down the needle holding Rin's blood on the table and grabbing another one to use for Len. When she turned her attention to the used to be puppy on the table she gasped.

"Oh my…you're a cutie when you're human." She gasped with wide staring at the little blonde boy who looked almost identical to the girl still tied up and growling at Teto. "Hn…w…what happened?" the small boy whimpered slowly sitting up, only to fall back not used to his now human arms. "Oh dear, it would seem I was distracted and you woke up." She sighed shaking her head. "Oh well, I guess this is gonna hurt a little bit." She giggled. Len gasped trying to lift himself up again, this time getting up and scooting back. "N…no…" he whimpered about to scoot back some more when his hand slipped off and hit air making him stop. "It's alright puppy-chan. This is only gonna hurt for a little bit." She smiled before grabbing a hold of the blonde boy's arms pushing the needle into his soft pale flesh making him yelp.

"Now you be good while I go and take notes of the effects. Come on Ted-kun let's go, I'm sure your curious as well." She giggled grabbing the other needle after putting a mark on the needle she used on Len. Be good in there!" she reminded one more time before leaving the room and locking the door so the two couldn't escape.

*Present*

"That's so sad." Keiko cried quickly wiping tears from her eyes as Rin just nodded with a sigh. "Yeah…but I finally got free from the ropes and helped Len-kun off of the table and all we could do was comfort each other. It wasn't till an hour or two later that they came back with the 'results' as they called it." She shrugged. "And?" the small blunette asked. "Well turns out that the potion that she injected inside us gave us the ability the become human, but to also still turn to our original form. Some of the side effects were that anyone we transformed around would be able to understand us when we become puppies again thanks to some strange wave length we give off when we do. That and we heal faster than people do but ya know it's not like 5 second healing…more like something that would normally take you or any human or dog a week it only takes us a couple days. It's the same for both me and Lenny…but Len got something more." She said grabbing a hold of the sheets.

Kaiko leaned forward practically begging the blonde for more information with her eyes. "Well…" she sighed. "It seems that the potion that she injected gave Len the um…well how should I put this…he can get prego." She finally said. Kaiko blinked before a blush made it's way to her face. "O..oh I see…then if he and Kaito-nii…kyaa!" she squealed jumping up from the bed. "That's so cute! So that's what you meant by little Lenny's running around."
