Hello! This is just a drabble series, nothing special :3

Yeah, and as you can see from the title and summary, this is an AU where Takano and Onodera are brothers and well…let's see what happens :33

And like I said, this is a drabble series, so there's no connection, just a bunch of ideas in mixed up order. Though, I'm contemplating on whether to let them be in a relationship or not, so that's still to be decided~

And…yeah! Hope you enjoy~

"Masamune-nii, can I ask you something?" Ritsu spoke softly as he knocked on the door.

"Yeah, come in." Ritsu entered his brother's bedroom and found him situated at his desk, studying. Masamune turned around in his seat and pulled his glasses off. "What's wrong?"

"Ah…well…" Ritsu trailed off as he plopped himself down on Masamune's bed. "Uhm…how do I put this…u-uh…" Ritsu stared hard at the ceiling, his face turning redder by the minute. Masamune sighed softly and moved over to where his brother was and sat down on the side of the bed and glanced at him.

"Just tell me bluntly." Ritsu chewed his bottom lip, before asking,

"How do you French kiss?"

Masamune blinked once, then twice, then…

"BAHAHAHAHAHAHAHA!"

"SHUT UP! I'M HAVING PROBLEMS YOU KNOW!" Ritsu shouted as he whacked the older with his pillow. Masamune fell off his bed, snickering as he clutched his stomach.

"Ugh, I'm leaving! I hate you!" Ritsu marched towards the door before Masamune grabbed his ankle.

"Waiwai-*wheeze* Oh man! Wait just give me- *snort* a minute!" Ritsu rolled his eyes and waited for his brother to calm down.

"Haa…" Masamune sighed before sitting back on the bed. "So, is this cause of your girlfriend or what?" Ritsu blushed, before looking away.

"Y-Yeah, I mean, it's not like she's asking for it or anything, but I thought I would try it." Masamune raised an eyebrow.

"Easy, just stick your tongue in her mouth." Ritsu blushed again and rubbed his face.

"Yeah I know! But…what after?" Masamune stared at his younger brother blankly.

"Did you seriously just ask that question?"

"S-Shut up! I'm new to this!" Masamune nodded and sighed.

"Okay, just shape your hand into lips and kiss it, then push your tongue in and do that shit for a few minutes and you've become a changed man." Ritsu glared at the other male, sighing exasperatedly.

"You don't think I haven't tried that yet?"

...

...

...

"BAHAHAHAHAHAHAHA! YOU'RE HOPELESS MAN!" Masamune hit the bed with his hand as he continuously laughed. Ritsu drew his lips to a thin line and scratched the back of his head.

"F-Fine, I won't do it then." Masamune calmed down from his laughing fit as he glanced at his younger brother in amusement.

"I'll go now, sorry for disturbing your studies." Ritsu spoke softly as he walked towards the door again. Masamune only sighed once more, knowing that his younger brother would go into a sulking session, due to the raven's teasing.

"Okay, Ritsu, I'll be serious, come back here." Ritsu turned his head to glance at the raven. Masamune beckoned him over with his hand.

"Walk back over here and stand in front of me." The brunette slowly shuffled over to the raven, prepared for another load of teasing. Masamune's tone suddenly changed.

"You're gonna have to promise me…that whatever happens in here, stays in here. Okay?" Ritsu blinked in surprise at his brother's low and serious tone, and gazed into amber eyes, finding no amusement in them. Ritsu swallowed heavily.

"P-Promise…"

"You swear on your life?"

"I-I swear." Ritsu stiffened slightly when his older brother stood, their proximity too close for comfort.

"U-Uhm…Masamune-nii?" Ritsu flinched slightly when he felt the brush of a hand close to his jaw. He felt his face being tilted up, and found himself looking into amber eyes once more.

"I'm going to show you..." Masamune murmured softly before pressing his lips against his brother's.

"Hnn?!" Ritsu jolted up in shock, feeling his brother's tongue running across the seam of his lips. Ritsu attempted to yell in protest before feeling Masamune's tongue slide into his mouth. Ritsu gripped the raven's shirt as his eyes slowly slid shut, his knees weakening slightly.

Masamune noticed this and wrapped an arm around the other, keeping him standing as he swirled his tongue around Ritsu's. It wasn't long before Ritsu responded and they soon found themselves in a battle of dominance. Masamune let Ritsu win this time before breaking the kiss for much needed air. Ritsu's eyes were glazed over as his cheeks were decorated with a heavy blush. Masamune chuckled softly at this as he caressed his younger brother's cheek.

"See? You know how to do it already." Ritsu's eyes slowly moved up to gaze at Masamune, who was smiling softly at the brunette.

"Good on you." Masamune released the other and ruffled his hair before heading back to his desk. Ritsu blushed at the realisation at what he just did - and with his brother too - and whipped his head around to yell at the other when-

"Masamune! Ritsu! I'm home!" The two brothers turned their heads around to the voice that had come from downstairs. Ritsu moved to open the bedroom door when he watched a hand slam it back close.

"W-Wha—…" A warm breath caressing his exposed neck cut off Ritsu.

"Don't tell anyone of what transpired in my room." Ritsu felt his cheeks burn up once more.

"Yeah right! Like I'd ever! Baka-nii!" The brunette spoke hurriedly as he rushed out of the raven's room. Masamune watched him run off and laughed softly.

Soooo…what do you think? :3
