Work Text:
Hell knows how long it took Mo Ran to get to this point. Months. Years. He’s been in love with his piano student forever. (Though, uh, truth be told, Chu Wanning is going to surpass him in another two years maximum, Mo Ran is pretty sure.) It started with just looking at his ridiculously beautiful fingers, and then his mouth, and when Chu Wanning hit puberty and transformed from this slightly awkward kid into this very awkward teenager, Mo Ran was lost.
He knows that he’s wrong, to have – and there’s no way to put it any other way, is the issue – groomed Chu Wanning into this, but…
How could Mo Ran feel truly guilty, when Chu Wanning is in the sheets below him, and he’s just accepted that his birthday present for his fifteenth birthday would be losing his virginity?
It’s not the first time they’ve had sex. But until now, for the past three months that Mo Ran has slowly been working Chu Wanning into his bed, they’ve kept it to finger and mouth things. Hell knows just how often Mo Ran’s made him come over the last few months, and how much he’s been working tirelessly to get Chu Wanning to feel safe enough with him to let himself be taken properly.
Honestly, the thought that no one else has ever touched (or will ever touch, for that matter) Chu Wanning like this drives Mo Ran up the wall.
But this? The fact that he’s going to enter him any second now, and he’ll be Chu Wanning’s first, properly? Oh, Mo Ran could not be a happier man indeed.
“…Laoshi,” Chu Wanning wheezes from below him, looking up at him with his eyes all dewy from the three orgasms he’s had when Mo Ran was eating him out. He’s accordingly wet, but Mo Ran is slathering some more lube onto himself anyway, just to make sure he really won’t hurt Chu Wanning. It probably will, one way or another, because of his size, but…
“Hm? What’s wrong, A-Ning?”
“I’m scared,” Chu Wanning mumbles a bit, with another look at where Mo Ran is stroking the lube into his cock, and then putting on some more of it. It’s silicone lube; Mo Ran made sure to get some (he’s used water-based for everyone else so far, but those were all adults, frankly, and also it wouldn’t degrade silicone sex toys, so that was his go to), because he heard that it lasts longer, and that it makes things even easier. He does want it to be painless for Chu Wanning, because he loves him. He knows that he absolutely shouldn’t love a fifteen year old, but here he is, so what’s there to do?
“You’ll be okay,” he whispers, leaning down again to kiss him. “I’ve stretched you out so much. I’ll go really, really slow, okay?”
He’s saying that, but it’s sort of difficult to believe himself, when he wants nothing more than to fuck Chu Wanning so fast and hard that he passes out.
Not today. He has to be careful today, so that he doesn’t scare Chu Wanning away.
“…Still, it’s so…”
“I know I’m really big,” Mo Ran laughs. “I promise it’ll hurt much less than you think, okay? It will at first, probably, but I’ll go slow, and I’ll let you get used. Just stay relaxed. Put your legs over mine, okay?”
Chu Wanning gives a shy nod. His cheeks are so red, and he looks like he might cry any second, and he looks so scared. Little idiot. Mo Ran leans down to kiss his lips again. He never cared much about kissing, not until Chu Wanning, but he’s just so…
At first, he responds, but then, he breaks off.
“Laoshi. What if I- what if I break?”
“You won’t break,” Mo Ran says. “I promise. If you’re too scared, we can stop. It’s your birthday, after all.”
“…I want it,” Chu Wanning breathes out, really quietly, barely audible. “I’m just scared anyway.”
That goes right to Mo Ran’s dick. He nods, and he takes Chu Wanning’s legs to rearrange them into the most relaxed position Mo Ran could be bringing them into, and then, he just starts rubbing his dick into him, spreading the lube all over. Chu Wanning is ridiculously wet all by himself already, though.
“…That won’t fit,” Chu Wanning complains again. Mo Ran kisses him once more.
“It will, and it’ll feel really good, I promise.”
God. He’ll actually be inside of Chu Wanning in no time. Mo Ran feels himself throb. He’s oing to be the first (and the last). He’s going to ruin Chu Wanning, and he’s going to ruin him for anyone else, and fucking nothing can stop him. Honestly, if he didn’t cherish Chu Wanning so much, he’d long have forced himself in.
His own breaths are coming out all short by now.
Mo Ran swallows once, and then he positions himself, letting the head catch on Chu Wanning’s hole, spread all open in front of him, his clit rising a tiny bit with each breath.
“I’ll be careful. Okay?”
“…Okay,” Chu Wanning gasps, and he grabs away at Mo Ran’s waist for hold, once Mo Ran starts pressing in just a little.
Chu Wanning is really tight. He’s always been really tight, and even with his fingers, Mo Ran always has to fight. It’s not necessarily tight inside, after a while; it’s just that Chu Wanning has the puffiest, prettiest little pussy, and that makes it hard to even get inside to begin with. But feeling even just the slickness of him, paired with the lube, the way he’s hot and wanting and open, it’s…
“God, you’re a dream,” Mo Ran says. He uses one hand to guide himself, and with the other, he spreads those lips, so that he stands even a chance at getting inside.
“Laoshi, it hurts,” Chu Wanning complains as soon as he pushes a little more, putting proper pressure onto him.
“It’ll get better when I’m inside for the first time,” Mo Ran says, kissing Chu Wanning’s forehead. “Just bear with it, alright? Breathe, baby, just breathe for me.”
Chu Wanning is clearly trying, but not even he can erase the pain written all across his face.
“In and out, okay?” Mo Ran instructs, running his hands down Chu Wanning’s sides. With anyone else, he might try to stimulate them a little more to distract them, but he feels like that’d be the exact wrong move to make. Chu Wanning is the type that needs to really concentrate on it. And besides, he’s so tight that if he tightened up any more on accident, if Mo Ran were to touch his clit, it’d probably be the opposite of helpful.
Mo Ran strokes his thumb over his sides, towards his belly button.
“Do you want to stop?”
“…No,” Chu Wanning whispers, and his cheeks are so red when he says it that Mo Ran almost has to laugh.
“If it hurts too much, it’s no use-“
“No, just- continue.”
“You’re sure?”
“Mn.”
“Okay,” Mo Ran whispers. He plants a very wet kiss on Chu Wanning’s lips, and pushes more.
The head pops inside. He feels it, and Chu Wanning opens around him, and he’s so tight it almost hurts Mo Ran.
“In and out,” he instructs again, “deep breaths. Relax. It’s just me, okay?”
“That’s why I’m-“ Chu Wanning bites his lip, and he doesn’t continue. But Mo Ran is inside of him, and Chu Wanning still looks like he’s in pain, but his face is slightly more relaxed. Mo Ran keeps touching him, soothing little motions of his hands all across his body.
“That’s why you’re?”
He moves a tiny bit. Just to make Chu Wanning crack. It works.
“…That’s why I’m nervous,” he admits, and tears gather in his eyes again. “Because it’s you.”
“Oh, A-Ning, you’re an idiot.”
“Because I know you’ve done it with a lot of people, and I know I’m already no good at any of the other stuff, so…”
“Okay, so, first of all, you can’t do anything wrong letting yourself get fucked,” Mo Ran laughs, which makes Chu Wanning look the tiniest bit aggrieved. “And if it doesn’t work, then it doesn’t, and we can try again later. Okay?”
Chu Wanning shakes his head. He sounds much shyer than usual when he speaks up again.
“…It hurts less, if you don’t move. It doesn’t feel like much now… pain-wise.”
Yeah. Just pain-wise. Mo Ran knows he’s a lot, in general. He’s big. Nothing he can do about it.
“Then I’ll just stay like this.”
It takes a long, long while of getting inside of Chu Wanning. Mo Ran stays hard though because hello? Chu Wanning is naked below him, an his dick is in him. Mo Ran physically cannot lose this boner. Not possible.
And eventually, he bottoms out. And Chu Wanning isn’t in pain, and Mo Ran is inside of him entirely. He’s the first to have Chu Wanning like this, and he’ll damn well be the last. Mo Ran will make sure of that.
God.
He can’t believe he’s actually inside of him.
For a good amount of time, they just stay like this then; Mo Ran stays inside of him, and he pets away at Chu Wanning’s hair, and Chu Wanning just clings to him. Eventually, it’s him that shifts his hips, like he’s begging to get fucked, so Mo Ran can’t resist, and his hips move of their own accord.
He’s fucking Chu Wanning. And Chu Wanning is liking it. The pain on his face fades into surprise, which Mo Ran is sure is because it doesn’t hurt.
“You’re okay?” he whispers, kissing Chu Wanning again, and the boy looks up at him, a small smile growing on his face suddenly.
“…Yes, I am,” he says, like he can barely believe it. Mo Ran nods, and he grabs some more lube to fuck into him after squeezing it onto his dick, and then, he properly gets Chu Wanning’s legs on his back and grins down at him.
“Well. Let me know if you’ve gotta stop, then, ‘cause I don’t think I’ll get myself to unless you tell me to.”
Chu Wanning’s hands on his back glide higher, until they’re in Mo Ran’s neck, and he takes a small gulp, before he nods. His fingers are so long, Mo Ran can feel the length of them even there.
“…Mn. That’s fine.”
“It’s your birthday present, after all,” Mo Ran says, and he leans down to nip at Chu Wanning’s ear, starting to move properly, in and out, pushing into him as deeply as he can, watching the way Chu Wanning’s face goes slack with it. “Happy fifteenth, A-Ning.”
