Warning: More steamy scenes in this chapter. If you don't like it, don't read it. I didn't plan to post this, but MM-Yumi (thanks for reviewing by the way! I'm glad you would like to read more) asked me to continue, and this was all I had... this fanfiction I wrote isn't really a story with a plot, it's just a mashup of some random Luka x Kaito stories I think of sometimes. Still, I hope you all will enjoy reading it... thank you~

Chapter 4

"Luka? What are you doing?" Kaito entered the pinknette's room and looked over her shoulders.

"Math," Luka replied miserably. Kaito looked at the worksheet that Luka was attempting. "Oh, I've done that already."

Luka's eyes sparkled. "Really?" Luka fiddled with her fingers, and asked, "Could I—" But Kaito replied bluntly, "No." Luka pouted. She tried again, giving Kaito puppy eyes, which almost worked, but Kaito crossed his arms and looked away.

"That won't do, Luka. That would be cheating," Kaito said disapprovingly. Luka held Kaito's shoulder, shaking it slightly. "Pleeease?" She begged, but Kaito didn't budge, though he really didn't want to reject Luka.

"Tell you what, for every correct answer you get, I'll give you... a hug," Kaito offered shyly. Luka raised her eyebrows.

"No, two kisses per question!" Luka negotiated.

"Fine, kiss, but one per question only," Kaito resented. Luka looked unhappy, but she would have to do with it. She got started on her worksheet with new motivation, and Kaito chuckled at her sudden attitude change.

"Then..." Luka said suddenly, "then, if I get it wrong, do I get any punishments?" Kaito raised his eyebrows. "Are you asking for punishment, Luka?" He teased with a hint of amusement in his voice.

"N-no! It's only if I get something wrong, that's all!" Luka stammered, red-faced. Kaito smirked. "I get to do something to you that you don't like."

Luka looked like she wanted to protest, but she shut her mouth and answered, "Fine." Then she got started on her worksheet again.

In a few minutes, Luka held her paper up proudly. "I'm done! Give me the answers, Kaito!" She exclaimed. Kaito rolled his eyes, and said, "Alright, alright." He handed Luka his worksheet, and Luka scanned it through with her excited blue eyes.

"Damn it, I got the first question wrong," she cursed. Kaito stifled a laugh. "Yeah! Punishment time for Luka!" He cried. Luka semi-glared at him, then looked back at the paper. Her eyes lit up. "Second, third and fourth one right... aw man, I got question 5 wrong. And sixth to eighth I got right."

Kaito's eyes widened. "How many kisses is that already?" Luka giggled, and answered, "6 kisses." Kaito grinned and shifted closer to the pinknette. "So, can I get started?" He asked softly, lips brushing against Luka's face. Luka blushed, and barely asked if the door was locked before Kaito's lips crashed into hers.

Luka leaned back, surprised, but quickly getting into the mood as Kaito kissed her. He's a good kisser, Luka thought dreamily as she opened her mouth, allowing Kaito to deepen the kiss. Kaito pushed harder, causing Luka to moan in delight, and she pushed harder too, not wanting to lose.

Kaito, however, was already achieving all dominance. His tongue explored every inch of Luka's mouth, while Luka sat back and enjoyed the sensations of pleasure hitting her like waves.

Finally they broke, and Kaito panted, "Okay, that's one." Luka opened her mouth in shock. "That's one? That must be worth at least 3 kisses!" She said. Kaito held her chin, staring at her lustfully. "Do you not want more kisses?" He asked. Luka shook her head, a smile on her face. "No, I want more... please continue, Kaito…"

Kaito smiled, satisfied, and started round 2. This time he traced kisses down her neck, one on her face first, then one just below her ear, followed by one on her neck, and one on her collarbone. Luka moaned, and Kaito began sucking on her collarbone a little, and Luka squealed. "T-that's ticklish, K-Kaito," Luka managed in between giggles.

Kaito looked up at her. "But you like it, don't you?" He asked. He stared at Luka's red face, and he thought, she's so adorable. Luka couldn't stop blushing, she didn't know how Kaito was so good.

"Did... did you have a girlfriend before, Kaito?" Luka asked suddenly. Oh, it was kinda stupid. How could someone so handsome not have a girlfriend before?

But to Luka's surprise, Kaito shook his head no. "W-what? Then… then... how are you... so..." she couldn't find her words. Kaito stroked Luka's face affectionately, not saying anything.

Luka blushed scarlet again. Kaito tilted his head. "Hey, what about those punishments, Luka?" He asked. Luka widened her eyes. "Hm? What?" Kaito eyed her. "You said it yourself, if you got a question wrong, I could punish you by doing something you don't like."

"O-oh... about that..." Luka averted her eyes, her mind starting to fill with dirty thoughts about how Kaito could punish her... Kaito smirked and stroked her hair. "So, how shall I punish you?" He asked, slightly seductive.

Luka blushed and said, "Are you getting some funny ideas?" Luka noticed Kaito becoming red-faced too. Was he thinking some... dirty thoughts?

Kaito poked her sides suddenly, and Luka gasped, barely holding in laugher. Kaito poked her again, faster, and Luka burst out laughing. Funny how they could have been making out like mad just a few moments ago, and now they were poking each other like primary school kids.

"K-Kaito! S-stop!" Luka laughed, and she doubled over to the floor. "No! I won't!" Kaito said mischievously, and he continued poking her even though she was on the ground. Suddenly he lost balance and he slipped—"Woah!"— and Kaito fell over to Luka.

Luka shrieked, and Kaito flopped down with an 'oof'! He realised his face was on Luka's chest. S-soft... it's so soft! Kaito thought. Amazing! How could he have never noticed this before! Luka's... breasts...

Kaito's face was redder than ever before. "I-I'M SORRY! I..." He pushed himself up, and realises he was pressing against Luka's chest. "…!" Kaito was frozen, his hand still on Luka's chest.

"I-I..." Kaito tried to think of an apology, but Luka suddenly said, "N-no... it's okay... I mean, I... I don't mind..."

Kaito's eyes widened. She... she doesn't mind...?

"You… you don't mind, Luka? Really?" Kaito asked, his face becoming red. Luka blushed, embarrassed as well, and said quietly, "If it's you... I don't mind." Kaito never knew such happiness existed.

"But... please... please be gentle," Luka said softly, looking away. Blood gushed out of Kaito's nose.

(Not literally.) How... how sexy...! Kaito thought, nearly fainting. Kaito planted another kiss on Luka's cheek, making her blush hotly.

What happened next is up to your imagination.

...

"Luka? Are you done with your homework? And where's Kaito, do you know where he is? He's not answering his messages…" Gakupo asked loudly as he pushed open Luka's door.

"He's literally ignoring me!" Gakupo cried, before realising what was going on. He stared at his sister and Kaito, who were staring back at him.

Kaito and Luka immediately separated, and Gakupo gaped at them. He noticed both of their shirts crumpled, one of the buttons on Luka's shirt coming off already for pete's sake, and he nodded slowly, and said, "Oh.… ohh... ah... sorry. Sorry, y'all can continue... it's not urgent, really, Luka. Just, yeah. Just… continue."

He gave Kaito a look that said, We are so talking later. Kaito sighed. The door closed.

A small silence followed, before Luka muttered, "I told you we should have locked the door." Kaito sweatdropped.

Luka looked at the blue-haired man and blushed again. He was so sexy like that, with a crumpled shirt and panting slightly. Kaito noticed Luka looking at him, and he shifted towards her again.

"I still have one more kiss, don't I?" He asked, smiling as his lips brushed against Luka's. He leaned in, but he only kissed Luka's palm. "Hm?" Kaito opened his eyes.

"After I do my math corrections, then you can have it," Luka said, smiling evilly. Kaito groaned, and pouted to himself as he watched his pink-haired lady write.

I have Luka x Gakupo stories in store too... any fans? Haha XD Also: I don't own Vocaloid. Obviously I don't, but I guess I had to put it there.
