Disclaimer: I in no way own Vocaloid

One: Prank
Meiko finds a way to amuse herself at Len's expense

Meiko yawned and fanned herself with her hand, as she opened her medicine cabinet. Well at least the medicine cabinet she shared with Miku, and Rin. While the blonde and tealette had various products and medicines on their portion of shelves, Meiko had only two items. A bottle of aspirin and a bottle of cough syrup that had only been used once. Meiko pushed aside the green syrup and instead wrapped her red painted fingers around the small bottle of pills. She pulled them out and set them on the bathroom counter, closing the cabinet.

Right now, the brunette had one hell of a headache. Mostly from her constant obsession with drinking. Maybe she should take it a little easy on the substance. At least to avoid the raging hang overs. And avoid embarrassing moments while intoxicated. Like the time she had kissed Kaito right on the mouth while Miku had a camera in her hands. The oldest Vocaloid had yet to live it down.

She flushed and grumbled to herself, remembering the morning she'd seen the photo, slowly opening the bottle. She set the bottle and lid down on the counter once she opened it. Grabbing the glass that was next to the sink she filled it with water and set it next to the bottle. She picked up the container once more and shook it onto her open palm. A thin brow slowly rose as two pills came into her hand. These weren't the right pills. They looked completely different. Meiko checked the side of the bottle and found that she had the right bottle. Why were there different pills inside here?

Then it sunk in. Someone wanted her to take these strange new pills as a prank. Something bad would happen to her if she took these, she was absolutely positive.

The brunette growled and went to toss the two pills back into the container, but then froze. This was supposed to be a prank on her, right? Well why couldn't she turn the chess board around? Make someone else take the pills and see what happens. Just for laughs?

With a sly smirk, Meiko left the bathroom and ventured into the living room, the pills balled into her hand. She found Rin on the sofa, watching television and nibbling on pieces of an orange. The television seemed to be showing some sort of game show. There were a handful of men wearing nurse uniforms and wandering around a hospital set up with gags, jokes, and actors. If the men were made to laugh, they were punished by getting a swift smack to the behind with some sort of paddle. The show was called "Gaki no Tsukai: Hospital Batsu Game."

Rin almost choked on her orange, laughing as one of the men suddenly fell into a booby trap in the ground.

"Hey, Rin, where's your brother?" Meiko asked, chuckling a bit herself.

"Len? He's in the kitchen." Rin replied, looking once at the older woman and then retreating back to the television. Meiko walked past the blonde girl and headed into the kitchen. Len indeed was in here, sitting at the table and doodling in a notebook while eating a banana. Meiko smirked inwardly.

"Hey, Len, can you do me a favor?" She asked sweetly, her tone being of a loving older sister. Usually she would ask Kaito to do this sort of thing, but currently the blue haired man was out, signing autographs with Miku, Luka, and Gumi. Currently the only Vocaloids in the house were herself, Len, Rin, Gakupo, Neru, Mikuo, and Teto. The last three of course were only here visiting. They said that being around Dell and Haku was getting a little awkward since sometimes more noises than necessary where heard coming from Dell's bedroom.

"Yes, Meiko-oneesama?" Len asked, unsuspectingly. He lifted his eyes from the notebook and looked curiously at his older sister figure. Len sadly, was the second most gullible person in the house, right after Kaito. The blonde boy almost never suspected anything from anyone. Though usually he was smart enough to figure things out, he had no time to discover what Meiko was up too.

"You see these pills?" She asked, holding out her palm. Len looked at them, and nodded.

"Yeah?"

"Well you see, these are new pills that I found that make you irresistible to the opposite sex."

"E-eh?! Seriously?" Len's eyes widened. Meiko smiled and nodded, smirking on the inside. Hook, line, and sinker.

"Yeah. These things work amazingly!"

"Wow! That's so cool! Is that why Kaito was trying to kiss you the other day?" Meiko nodded, remembering how the blue idiot had tried to return the drunken kiss that Meiko had given to him, only to receive a very painful kick to his manhood. Right in the bean bags. "Where did you get them?" Len asked, fascinated by the small medicines.

"That's a secret, Lenny." She said mysteriously, holding a finger to her lips. Len's eyes widened in a child-like fashion.

"So what's the favor, Meiko-oneesama?" He asked. Meiko almost felt bad, noticing the trust lacing Len's voice. Almost. Then the feeling of amusement took over.

"I've only tested these so far on myself. I want to know if they'll work the same way on a boy as they do girls."

"You want me to try?"

"I'm trusting you with this secret, Lenny-kins. Don't disappoint me." Meiko said, placing the pills into his hands. Len looked at them, then back at her and nodded.

"I won't Meiko-oneesama! I'll keep this to myself." He said, then popped the pills into his mouth and swallowed them. That was easier than Meiko thought it would be. Len was in a very trusting mood today.

"Maybe you should go see if it works on Rin? She's in the living room."

"O-oh....Ok." Len mumbled, hopping off his chair. He pushed it in under the table before leaving the room. Meiko snickered under her breath watching him leave. She contemplated whether or not to go watch Len put the moves on his sister when Neru walked into the room, looking flustered. Meiko raised a brow, watching the blonde girl dig through the drawers and cabinets and even in the refrigerator.

"Uh...Neru?"

"Oh...Meiko...." Neru muttered, noticing the company in the room. She shut the door to the ice box and walked to the table, leaning onto it on her hands.

"Lookin' for something?" Meiko asked, picking up Len's notebook and flipping through the pages. Len was very talented with a pencil. Neru sighed.

"Did you move your aspirin bottle?" She asked. So! Neru was the culprit!

"You mean this?" Meiko asked, showing her the bottle in her hand.

"Yes! I've been looking all over for it! You didn't take any, did you?" Neru asked, her eyes brightening. Meiko raised a brow.

"Um...no. What are these? These aren't my pills. I noticed right away so your little prank didn't work."

"What? Oh...no! No! No! We didn't mean for you to take them Meiko." Neru held up her hands. Meiko blinked.

"What?"

"No! We um....were trying to play a prank on Mikuo. We were going to give him those in his tea, but he almost found them in my bag so I had to hide them in your aspirin bottle. Sorry."

"...S-so what are these exactly?"

"Uh...." Neru laughed a little, blushing. "Viagra?"

"PFFFT! So that's what these are!" Meiko laughed, looking at the pills. "Oh I would love to see Mikuo's face when he-.....Oh my God.." Meiko cut herself off, her face falling.

"What?" Neru asked.

"KYAAAA!" SMACK.

Both of them turned toward the living room hearing Rin's scream. Meiko snorted a little, biting her lip to keep from laughing. Neru narrowed her eyes and looked at the brunette.

"You didn't.....?" She trailed off as the female Kagamine stomped into the room. Her face was bright red, as well as her left hand. Obviously she'd slapped her twin. Rin turned to Meiko, glaring and walked up to the woman. Meiko raised her eyebrows in fake curiosity.

"What. The....hell, Meiko, did you give to Len?" Rin whispered harshly. Meiko squeaked, holding back her laughter.

"Magic pills." She replied, moving her hands dramatically.

AN- Ohohoho~...Ah, Len.....We all know Rin liked what she saw. :3
