Sora is extremely brave to a lot of people. Especially to Riku. Sora's the whole reason the two of them got together. He had the courage to divulge his feelings to Riku. Well, it's a little more vulgar than that…
Riku and Sora, of course, are best friends. They've been best friends for Sora's whole life, since Riku is two years older than him. The two do everything together. And they talk about everything together. So, of course feelings of more than friendship would arise from this.
Anyway, back to how Sora told Riku. They were at a party, like most high school students. After a while, though, they lost track of each other. Sora, being the good person that he is, looked around for Riku.
Not finding him on the first floor where most of the people were, Sora went upstairs to where the bedrooms were. At this point in his life, Sora was still a bit fuzzy and naïve about the whole sex deal. For all we know, he probably thought people were playing card games in the rooms.
Poor Sora didn't know how to go about searching the rooms without interrupting people's games, so he just called Riku's name through every door until he got an answer.
Though the answer did sound a little strained and breathless.
"Riku, are you okay?" Sora asked since he didn't know why Riku sounded like that.
"…Sora go back downstairs…we'll leave…in a few ok?"
"Jeez Riku, why do you sound like that?" Since Sora was such a good, and still quite naïve friend, he opened the door to see what got Riku so short of breath.
The look of shock on his face probably couldn't have been more perfect. And the fact that the girl didn't even pause in her ministrations made it even better…or worse, depending on the point of view.
As close as the two were, it's never good to be caught getting a blow job, so Riku apologized to the girl and asked her to leave. Well, actually…
"You're dismissed." Riku said as he pushed the girl away from his crotch. He pulled his pants back up and gave Sora a Look.
"Aw man, I'm sorry Riku, I had no idea." A blush was splattered none-to-gently on his young face. "You coulda just told me to leave"
"No, it's fine. You ready to go?" Riku rubbed a hand down his face.
Sora didn't seem to hear him, though. As a matter of fact, Sora was having a bit of self-realization in that moment. The small glimpse that he got of Riku's… junk made Sora really happy in a few ways he couldn't explain.
Also, the way Riku looked right that moment made Sora's heart swell with unknown feelings. Taking those, and a few other things, into account; Sora came to the conclusion that he liked his best friend.
While this small epiphany happened, on the outside, Sora was staring off into space with a shocked look on his face. From Riku's point of view, that would probably be a bad thing.
"Sora?" He waved a hand in front of the non-responsive face. "I'm sorry you had to see that. It's just that…" Sadly Riku couldn't get the words out. He didn't have the innocent courage that his younger friend with mutual feelings had.
At this point, Sora accepted his self-admission and decided to do something about it. His eyes snapped back to focus as he looked for something to say that would make Riku laugh and love him at the same time.
Though it was faintly visible and Riku hid it well, Sora saw his opening and grabbed for it. Literally.
Riku's eyes bulged and his breath left him in a gasp. Anyone would be shocked if they were groped in the middle of speaking.
"Why'd you put this away, Riku? I wanted some." Sora said it with an expression that made Riku rethink what the boy said. Though after a few seconds of dissecting the innuendo and being groped by his love interest, Riku stopped thinking.
And he gave Sora some. Maybe even all.
