"Hmm? Miku-nee, what's wrong~?" Luka asked her shorter sister in their bed, a hint of worry in her tone.
Miku looked into Luka's eyes, which were filled with something that Miku wasn't sure she'd seen Luka express - concern for someone. She turned her head away quickly knowing that it wouldn't take much for her to tell anything to that one person in this in world.
"Nothing's wrong, Luka," she mumbled.
"Oh? But you're not acting the same way as you normally would~" The other girl's response was laced with a seductive tone, one that would win over anyone.
Luka continued to press her surprisingly soft lips against the shorter girl's, both of her legs wrapped completely around the other. Miku moaned at she felt Luka bite down gently on her bottom lip, and a hand run through her long, slightly messy hair. Both of their clothes had been long forgotten earlier, and all that was there was a thin white sheet covering them both.
A delicate finger ran down Miku's cheek, caressing the flawless skin that she had. Hard kisses followed after, all along her jaw line, making Miku want more.
"Can we please...?" Miku asked, her skin getting a little chilled now.
"No, no, no, you have to tell me," Luka purred, fingers tracing the latter's collarbone, and down to her breast.
Miku's face was flushed now, this was the first time Luka had refused to go farther with her...
"You'll think I'm stupid!" Miku whispered, she already feel her eyes stinging.
"Nonsense, you're not stupid," Luka said firmly, giving another kiss to her lover.
"I am stupid! Someone as pretty and smart, and wonderful like you doesn't deserve someone like me!" Miku exclaimed, surprising Luka with her sudden voice raise.
Luka stopped with the kisses, and looked at Miku straight in the eyes.
"That is the most bullshit statement I have ever heard in my entire life, true, I am stronger than you as the newer Vocaloid model, but still, that's ridiculous."
Miku gasped at this, she had never heard Luka talk like that ever in her life.
"You are the greatest person I have ever met," Luka whispered, caressing the shorter girl's face again. "You are gorgeous, more experienced and smarter than me, and I love you so much. And I'd go to the ends of this world for you."
Miku blushed, feeling the tears stinging in her eyes. To think that she really was just more than a sister, or a sex buddy to Luka...
"And I mean it."
Luka smiled slightly at Miku, kissing her lightly before getting off of the bed. Miku immediately sprang up, and jumped off the bed too.
"Where are you going?" she asked, catching Luka by her bare arm.
The other girl smirked, and pushed away part of her unkempt bangs with her other hand.
"You said you wanted to do something else, didn't you?" An irresistibly seductive tone to her voice.
"You can't do that without lube, now can you?"
