Yui wakes up briefly when Akio gets out of bed to go to work, but the twins both have the day off, so he cuddles back up to his brother and dozes off again.
The next time he wakes up, he has a familiar, mildly annoying sensation. It's a feeling in the pit of his stomach, kind of like a pressure, and his penis is half way hard. He gets like this maybe once or twice a month, and in the past it's always just been an inconvenience, solved by a quick rubbing one out.
Except now, he can feel his beloved brother nuzzling in by his neck. It very quickly becomes evident that he should probably be using these rare moments as an opportunity with his boyfriends. He kisses Yue's hair gently.
"Mmm, morning," Yue replies. He'd only really been half awake -- which is more than awake enough to be snuggling into his love, but hadn't really been doing much in the way of conscious thinking before that kiss.
Yui presses another soft kiss to Yue's head, before answering, "Good morning." And then he realizes that he doesn't really know how to express what he's feeling. "Mm, Yue?"
Honestly, the younger twin hadn't been planning on moving from his lovely position all snuggled up with his face in the crook of his brother's neck, but the tone in Yui's voice suggests the older man wants to speak, so he moves back enough to be able to tilt his face up. Only to see his brother clearly wanting to say something and just as clearly not quite sure what to say. "Huh, what's up?"
"Um, so I just woke up and I feel kinda..." Yeah, Yui isn't even aware enough to have terminology to explain it, and he can see his adorable little brother looking at him expectantly, so he carries on, "So like. Sometimes I wake up and there's this feeling? Especially by my stomach, and I usually go -- help myself out? And I feel like that today."
Usually Yue understands Yui very well, sometimes not even needing the other man to finish speaking. Today is not that day, although it's not *his* fault that the guitarist is describing a totally normal bodily thing as if he's an alien. "You're horny."
And then the excitement sets in, because honestly, he hadn't realized that Yui *could* feel horny. Like obviously Yui can get turned on, but to just become horny without someone putting work into it? So that's fun. NOW he feels on the same page, so he smiles, "And~ since you're horny, it's more fun to have me help out than doing it yourself, right?"
Yui blushes lightly, because although it's convenient to have Yue figure out what he was saying, he's still not super great at hearing things said frankly yet. He's working on it, because he's learned it's important for consent and stuff, but it does not come naturally. "Yes, that's what I was thinking..."
"Wonderful~" Yue replies honestly. The idea that Yui could wake him up this way, however occasionally it may be, is very invigorating. He leans in immediately to press his lips to his boyfriends'. As always, he loves the way that their kisses just seem effortless as they're anticipating each other's movements. Today he's especially loving the way Yui's hands are already starting to roam over his back.
The horny edge definitely has the guitarist getting into it more quickly than usual. They were already topless as that's pretty commonly how the trio sleeps at this point, and they were already curled up close.
The idea of putting to use this feeling, which he had always found annoying, and that he can use it to help make up for his (perceived) lack in the sexual department is just such a huge win. After a few breathless kisses, Yui bring shis mouth to the younger man's neck, delighting in the soft moan that releases.
Yue is surprised but definitely pleased to wake up and find himself in this position. He lets his hands roam over Yui's back in turn excited as always for a chance to touch the man's he's been in love with for so long; the man he thought he'd never have a chance to touch like this.
Yui trails his lips down Yue's neck to the other man's collarbone -- at which point it becomes obvious that this side-by-side position is not really the best for what he wants to do. Struck with an impulse that he'd had once before with Akio, he brings a hand up to Yue's shoulder and pushes the other man down against the bed. He had not anticipated the loud moan that his move prompts, and ohmygod that expression on the younger twin's face!
Yue doesn't typically feel jealous of anyone doing anything to anybody else in this relationship, but that one time Yui had pushed down Akio had been the one time. Especially since Yui was showing a sudden dominant streak to the most dominant person around instead of Yue who gets *off* on this stuff. So to finally -- Finally! -- have it done to him instead. Of course it makes him moan! Just feeling Yui on top of him, that hand pushing down on his shoulder, that presence is enough to get quite a rise out of him.
It's not the most amazing expression he's witnessed on Yue's face, but he thinks it's the best one that he's been the cause of. And he wants more. Yui wants, maybe *needs* to be able to give Yue that kind of pleasure as well. He's definitely seen Akio push Yue down like this so it makes sense.
Of course, while the older twin is processing, things aren't really progressing. Yue gets his head back, and gets nervous that having such a big reaction had freaked Yui out. He definitely doesn't want the other man to stop now! He runs his hands down the outside of Yui's arms and says, "You don't have to do anything different than normal. Like, yeah, I like this position, but this position doesn't have to be fucking, you could still jerk me off like this, if you want."
Yui appreciates that option, really he does. But he knows how much Yue has been wanting this. Even as the younger man is suggesting handjobs, he can see in his expression that that's not what he really wants. He's settling for that, because he doesn't think he'll get what he wants. Ultimately, that's what decides the guitarist; he wants to give his love what he wants. "But what if we did?"
Yui stays there, on top of Yue, hoping to wait out the concerning period where Yue's brain appears to have entirely frozen. He smiles as Yue finally manages a small "Really?"
"Really. I mean, I'll try at least. You're gunna have to help me out though," Yui replies, quite certain his brother will have no trouble with that. Plus -- he has seen Akio do it a few times now, so he thinks he has the gist.
"Of course!" Yue replies, with an obliteratingly powerful smile of pure joy.
