Izaya was a sucker for kisses. Any kinds of kisses. From passionate to butterfly ones and Shizuo, being as madly in love with him as he was, always gave him what he longed for, but as the biggest rivals of Raijin high school, they did not have so much time to share them – until Izaya did not got a job in the library as an after school activity.

"Are you okay, honey? Your lips are really swollen lately," his mother asked Shizuo, who choked on his bite.

"Ehvthin okhay," he coughed, trying not to choke because of his food. From the corner of his eye, he got Kasukas' knowing gaze which made him flinch. Sometimes he had the feeling of his little brother having the ability of seeing into his soul.

After dinner had ended, he was lying on his bed with his arms being enlaced under his head. He closed his eyes and sighed tiredly. That day was pretty long. Suddenly, he heard his phone ringing. When he picked it up, a too familiar voice could be heard from the other end of the line.

"Shi-zu-chan~" Izaya sing-sang into the phone, making Shizuo groan. "Aren't you happy to talk to me?" Shizuo saw crystal clear his adorable pout.

"What do you want, Izaya? Today was tiring."

"Well, jumping that high must have been tiring," Izaya answered, nodding to himself, "but the way your PE t-shirt let us see a little bit of your delicious belly was really arousing…" Shizuo groaned again. He turned to his stomach and buried his face into his pillow. That's why he hated high jumping. "The main reason I called you for is… would you like to meet me after school tomorrow?" The ice broke and Shizuo heard the little bit unsure and embarrassed voice of the boy Izaya really was.

"I have other plans for tomorrow. And we spent time together after school yesterday as well," he said on a teasing voice. As a reply, he got the this-is-not-funny-Shizu-chan voice from Izaya which made him laugh.

"Stop laughing!" Izaya said really embarrassed with redness on his face. "And stop patting my head in your head as well!"

It was around 4 PM when Shizuo stepped into the library. Right then, only just a few students lingered there and behind the counter, there was Izaya's coworker, who greeted him with a kind smile. Their library had a whole section for martial arts books, so he was a returning person there. When he reached the section mentioned before, a hand grabbed his sleeve and as soon as he disappeared behind the shelf, he felt Izayas' hungry lips on his own.

"It looks like you missed me pretty much, hm Izaya?" He asked, placing a little kiss on the others' lips after they had parted.

"It is not true," Izaya mumbled, looking aside.

"Really? You didn't?" Shizuo asked him on a loving voice, while turning his head towards himself by grabbing his chin. He leaned down and placed a chaste kiss onto his lips.

"No, I did not," Izaya replied, looking up at him with challenge in his eyes. Shizuo only smiled down at him which made him blush deeply.

"And now?" He asked, after he had placed butterfly kisses all over Izaya's face. Seeing his blush deepening, he knew the goal was near.

"N-no," Izaya said, but after the peck he had gotten on his nose, he had to take a deep breath. He knew he had to keep holding on. "N-n-n-n-o", he stuttered as red as a tomato.

"And now?" Shizuo asked on a low voice after he had kissed Izaya on the place he loved being kissed the most: the middle of his forehead.

"W-well… Maybe?"
