~flashback, 15 year old Matsuno's~

"Choromatsu. Choromatsu, wake up." Osomatsu whispered softly into his brothers ear, gently shaking him in an attempt to wake him up. After a few minutes, seeing no progress in waking Choromatsu, he shoved him a bit, resulting in Choromatsu sitting straight up, quickly looking around like something bad was happening.

"Wha-!?" Choromatsu blinked a couple times only to see nothing but the faint figure of his eldest brother sitting up with him. He rubbed at his eyes, still half asleep. "Osomatsu nii-san?" he yawned. "What time is it?"

Osomatsu shrugged, looking at the clock behind them, seeing nothing but the fuzzy outline of the clock. "Probably like...two in the morning." Even with it being dark, he could tell that the look on Choromatsu's face was none too pleased, which made him laugh a bit. "I swear I didn't wake you up for something stupid."

A soft sigh left Choromatsu's lips as he rubbed his temples. "What could possibly be so important that you had to wake me up in the middle of the night?"

"Because it was keeping me up and I won't be able to fall asleep until I tell someone." Osomatsu leaned back a bit, keeping himself up with his hands behind his back. "I was just thinking..." having been such an open person, he wasn't at all worried about saying it, "what would it be like to, y'know...kiss a guy." He chuckled softly to himself. "I'm not saying I'm gay or anything, it's just...I'm curious."

Choromatsu groaned, lying back down and covering his head with the shared blanked. "If you're so curious, the go and kiss a guy, why should I care about what you do with your personal time?" He was only up for five minutes and he was already done with the day. Closing his eyes, he started falling asleep again, only to be moved by Osomatsu.

"Kiss me," Osomatsu whispered, lying down on his stomach next to his brother. "Just once. I swear I won't tell anyone."

The sudden request made Choromatsu's eyes shoot open, removing the blanket to stare at Osomatsu with wide eyes. He would deny it later, but it had made his face go complete red. At first, Choromatsu couldn't find the right words, his mouth only open slightly. He blinked before he glared at his brother, shaking his head, stuttering out his words. "N-no way, Osomatsu nii-san! Y-you're my older brother, it's disgusting! I'm going back to bed, goodnight!" He quickly covered his face, wanting to hide any proof that he was blushing.

"C'mon, pleeeeease?" Osomatsu begged, pouting out his lower lip, shaking Choromatsu lightly. "I promise I won't tell mom or dad or the others. I just need to know what it would be like." He shook him a little more harshly, whining a bit. "Please please please please pleeeeease? Just once?"

Choromatsu sighed once more, uncovering his face and sitting up. He pinched the bridge of his nose, eyebrows furrowing as he couldn't believe what he was about to say. "Alright alright, fine. But only this once. And if you tell anyone, I swear I will kill you."

Osomatsu smiled and sat up quickly. He placed a hand on his heart, raising the other one. "I swear that I will not tell a single soul."

Rolling his eyes, Choromatsu grabbed his older brother by the collar of his pajama shirt, tugging him close. With slight hesitation, Choromatsu leaned in, closing his eyes as he locked lips with Osomatsu, resulting in a small squeak coming from the older Matsuno. Osomatsu couldn't believe that Choro caved in and kissed him, which made him smile a little. In a short moment, his eyes fluttered shut, snaking his arms around the small figure and pulling Choromatsu close to him, kissing him back with some soft, sweet tenderness that he never imagined he'd ever do. And for some reason, he felt like he was floating. The longer the kiss lasted, the more he melted into Choromatsu's touch. He never wanted it to end.

Unfortunately for me, Choromatsu showed no signs of continuing the kiss, pulling away after 10 seconds. His face, the same shade as a tomato at this point. He looked at Osomatsu with a look of annoyance. "Happy now?" he asked. He wouldn't say it out loud, but inside he actually felt butterflies, wanting to kiss him again.

With a smile and a nod, Osomatsu let his brother go, lying back down on his side. "Very." He closed his eyes, only to open them again when he felt Choromatsu snuggle up against him, making his heart skip a beat. He smiled a little more, wrapping his arms around him once more and closing his eyes.

"If you tell anyone about this too, I will actually kill you," Choromatsu mumbled, dozing off.

Osomatsu chuckled, holding him gently. "I won't tell anyone..."
