Work Text:
Osamu and Yuma had nothing important to do all day. They were the only ones currently at Tamakoma as everyone left earlier. Chika went to HQ for some training, Karasuma had a part-time job to go to, and Reiji along with Konami took Yotaro to a local park. Of course, Jin didn't say anything other then he had "something to attend to" before he left without giving anyone the chance to ask more questions. They also didn't have defense duty until later that day. Typically this would be the best time for training, but the two of them spent their free time talking. More specifically, it was Yuma asking questions and Osamu teaching him more about Meeden.
After being there for so long, the Neighbor had gotten used to life in Mikado. Yuma was just being curious. Thinking back to some old conversations he heard in passing, Yuma remembered when their classmates were talking about first kisses.
"Osamu?"
"Yes, Yuma?"
"What's a first kiss?"
Osamu stared for a second before he questioned, "Are you asking what a kiss is?"
Yuma put his hands behind his head, "Yeah. And why is the first one more special than the others?"
Adjusting his glasses, Osamu paused to think.
"A kiss is an action used to show you love someone, and... it's for a different love from what you feel for your friends and family. Kissing's usually reserved for romance. A kiss itself is, well, you put... uh... your lips against another person's and keep them there for a bit then..."
Unsure of how to properly end his sentence, Osamu went quiet for a beat.
"You move back and smile?" Osamu continued, unsure of his words. "First kisses are special because... they're usually done with your first lover, and people tend to cherish those memories, I suppose."
"Huh, I see."
Yuma thought for a bit as he put his hand to his chin. "Have you had your first kiss yet?" he asked.
Osamu, having not expected the question, felt a blush spread across his face.
"Ah... no, not yet."
"Do you want to have a first kiss?"
"Yeah, I suppose so."
Embarrassingly, the thought of Yuma being his first kiss flashed through Osamu's mind. He looked away, hoped his face hadn't gone red, and waited until Yuma started speaking again to glance back.
Yuma could see it wasn't a lie, but he didn't know if there was someone Osamu specifically wanted to kiss. Yuma being Yuma, he wanted to find out if there was.
"Do you want Chika to be your first kiss?"
"Huh? No! And- and you know I don't like her like that already."
"What about... Kitora then?" Yuma chuckled slightly as he asked.
"No, she's just someone I look up to. I also don't know her too well either." Osamu decided not to mention how, at times, Kitora could be somewhat... stuck-up.
"Well..." Yuma leaned forward just a bit while in deep thought. While he really tried to come up with some people Osamu could possibly be "into," Osamu was just thinking about how Yuma had been slowly moving closer to him—even if it was just by a bit. Osamu turned his head away, embarrassed again by his own thoughts.
"How about Karasuma?"
Osamu replied without thinking, "He's attractive, but I think there's someone else I'd rather have my first kiss with."
Yuma hummed and thought about what to do next. He took this minute to stare at his friend. Osamu's peridot irises were a beautiful contrast to his dark, ebony hair. And his glasses drew people's gaze immediately to his face. Yuma noticed the blush dusted over the other's cheeks and nose. A thought appeared in Yuma's mind:
"Cute..."
Yuma shook the thought from his head and returned to his original goal. Although Osamu knew quite a few people, there were only a couple he was actually close to.
After a short internal debate, Yuma drew a breath and tilted his head slightly before leaning forward. He pressed his lips against Osamu's. Osamu didn't know how to react. Before he could do anything, Yuma leaned back with a smile on his face.
"Like that?"
Osamu was left flustered, and it very much showed. Yuma kept smiling, but inside he couldn't help feeling nervous. What was Osamu going to say? Maybe this wasn't the right thing to do.
After staring in silence for a moment, Osamu finally forced himself to reply.
"Uh, y..yeah... I guess. Like that."
His face was still burning red, and he fidgeted with his glasses out of restlessness. Yuma's smile grew wider. He leaned back in—slower this time—and stopped just barely an inch away from Osamu. Smugly he asked, "Then would it be okay if I did it again?"
Instead of giving a verbal answer, Osamu filled the gap between them. Yuma didn't mind at all. This time the kiss was longer, but just as sweet as the first. Not exactly sure what to do, Osamu put his right hand gently on the Neighbor's shoulder. When they broke apart for a moment to catch their breaths, Yuma peered into Osamu's eyes again. Then they moved simultaneously and slid their mouths together once more. Yuma clutched Osamu's waist with his left palm. Osamu took the boy's free hand and linked their fingers together.
They were both quite happy with this turn of events.
