Mo Ran is in love with his professor.

Now, that wouldn’t be such a big thing, normally. Plenty of university students develop crushes on their teachers. Plenty of people have tried to seduce their professors. And some have even succeeded.

However, the problem is that all those people’s professors weren’t Chu Wanning.

Chu Wanning.

How does Mo Ran even begin to describe this man?

When he’d first took this class, it was only because it was a prerequisite for another compulsory paper—Mo Ran hadn’t really wanted to do 3D Mechanics, but fortunately, the class had very little students. Mo Ran had found out a little bit too late that it was because of the professor.

Apparently he was a tyrant.

Chu Wanning had been a professor there for many, many years, and yet people feared him. They talk about how his standards are so high one would be lucky to even get passing grades. They talk about how Chu Wanning did not explain things sufficiently and how no one understood him. They talk about how the professor is cold and mean-spirited, about how he barely gives his students more than a passing glance as he comes and leaves each class.

None of the rumours talked about how pretty he is.

When Mo Ran had walked into the room on his first day in the year, his jaw had almost dropped all the way to the floor.

Chu Wanning is beautiful. His waist-length hair is pitch black and tied halfway back with a ribbon. Mo Ran can absolutely confidently say that he’s imagined that hair splayed out on pillows or grasped in his hand more than a few times. And the rest of him is…well, with Mo Ran’s limited vocabulary, he can only repeat—beautiful.

Chu Wanning, it seems, takes meticulous care of his appearance—he wears slacks and button-ups, usually, but the first day Mo Ran saw him, he’d been wearing black slacks and a dark-red button-up with a black tie.

Mo Ran had fallen in love. With his looks, at least.

As time went on, it appeared as if the rumours were true; that Chu Wanning really was a heartless professor who did not care about his students. He barely paid attention to Mo Ran, and Xue Meng, taking the same class, even complains from time to time that Chu Wanning was too harsh with grading their papers.

Mo Ran himself is quite indifferent to his professor. His grades aren’t the best, but they’re not the worst, and really, that’s what matters—that he isn’t going to fail again.

So everything’s fine.

And then, one day, all of Mo Ran’s beliefs had been shattered.

It had been a rainy day, and Mo Ran had come out of his last class late, so he didn’t have anyone to share an umbrella with. He’d just resigned himself to stay here until the rain passed to get back to his shitty run-down apartment. Which, will probably have a leakage, considering that it’s a literal dump of a place. He can’t complain very much, but he will complain.

Thunder shakes him out of his reverie. It’ll take much longer for the rain to stop, he thinks.

And then, he sees movement out of the corner of his eye, from where he’s sitting on the steps under the porch.

It’s Chu Wanning.

When the professor sees him, he looks like he’d want to do a double take.

Instead, the professor says, ‘Mo Ran?’

Mo Ran blinks. Huh. He didn’t know…that Chu Wanning actually knew his name.

‘Laoshi,’ he says, standing up and brushing himself off—and now he doesn’t actually know what to say. Great. ‘You’re heading home?’ he says, very lamely, in the end.

Chu Wanning doesn’t laugh at him, which is already a plus in Mo Ran’s book. ‘And you?’ his professor asks, looking him up and down, probably looking for an umbrella.

Mo Ran grins, looking abashed, ‘Ah, I forgot my umbrella. I’ll just wait here until the rain lets up.’

And Chu Wanning frowns. ‘That would be too long,’ he murmurs softly, and then pulls out his own umbrella and gestures to Mo Ran. ‘Come. I’ll walk you home.’

And in a daze, Mo Ran lets himself walk beside his professor. It’s only now that he realizes that Chu Wanning is shorter than him, and not unnoticeably either—the top of his professor’s head only reaches Mo Ran’s chin. Fuck.

The walk is entirely silent for the both of them; Mo Ran being absorbed in his own thoughts and Chu Wanning not speaking much in general. Fortunately, Mo Ran’s apartment isn’t a long way from the university, and pretty soon they’re at his place already.

‘Thank you, laoshi,’ Mo Ran says, bowing his head a little, ‘I really appreciate you taking the time for me like this.’

‘It’s not problem,’ Chu Wanning says softly, and then he smiles just the tiniest bit at Mo Ran, before turning away, out into the rain again.

It doesn’t escape Mo Ran’s notice that Chu Wanning’s entire right sleeve is soaked. In a daze, he reaches up to touch his own clothes. He’s entirely, completely dry.

He’d been walking on Chu Wanning’s left.

…fuck.

And that’s the day that Mo Ran actually, irrevocably, falls in love with his professor.

(It might be a stretch, to say that so soon, but when asked in the future about his feelings, Mo Ran will admit to himself that that was the day he started seeing Chu Wanning in a different light.)

So that explains how he’s here, in Chu Wanning’s bedroom, staring into the bedside drawer—that contains a myriad of sex toys.

Dildos, to be exact.

Well, no—that doesn’t entirely explain why Mo Ran is in his professor’s bedroom. But after that one day, Mo Ran had worked up the courage to go to his professor during office hours to ask about a chapter he’s absolutely sure he’s going to fail, half-believing that Chu Wanning, like the rumours say, is going to turn him away and tell him to just study harder.

He doesn’t.

Instead, when Mo Ran walks in, Chu Wanning looks up at him and says, ‘Did you need anything, Mo Ran?’

And his voice saying Mo Ran’s name does things to him.

Mo Ran had admitted he needed help with a chapter he entirely didn’t understand, and Chu Wanning had nodded understandingly and swept the papers he was grading to the side to make space for Mo Ran’s books.

They’d both gone home late, absorbed in the material—Mo Ran’s absolutely sure that Chu Wanning’s taught him at least half of the course material in a little less than four hours, with detailed explanations and drawings that Mo Ran actually understands. It’s a bit surreal, actually, to get all this information and be able to process it.

Chu Wanning had waved him off when Mo Ran had asked if he wanted him to walk his professor to his house, saying that he still needed a few things to take care of.

‘Mo Ran,’ he’d said, once Mo Ran reached the door, ‘If you have any other questions, you can ask.’

And Mo Ran’s heart had fluttered in his chest and he’d squeaked out an okay before fleeing.

Which leads them to where they are now—metaphorically—because Mo Ran had admitted that he learned a lot better when it was a one-on-one session rather than in class, and Chu Wanning had suggested that Mo Ran come over for extra sessions.

Mo Ran had been ready to get onto his knees to thank his professor that time.

(And what’s worse is that Chu Wanning doesn’t accept payment. Mo Ran would’ve liked to think that this was some tuitions outside class, but when Mo Ran had tried in vain to pay his professor, Chu Wanning had merely said, ‘You’re my student. It’s my duty to help you. Also I don’t want to be accused of falling for bribery.’

Mo Ran had laughed helplessly over that, but then he also made a point to learn his professor’s favourite drinks and snacks so he could at least buy them as a thank you to his professor. At least Chu Wanning had accepted those, though his expression says that he knows exactly what Mo Ran is trying to do.)

And that leads to where Mo Ran is right now—again, still staring at the drawer of fucking sex toys that Chu Wanning apparently owns.

And it’s not just normal toys either.

Chu Wanning is on a whole another level.

The fucking dildos themselves are fucking big. Mo Ran had always thought that Chu Wanning was maybe averse to sex or came from a traditional family—he’d never expect his professor to have fucking ten-inch dildos kept in his bedside drawer.

Almost unconsciously, Mo Ran puts his hand in the drawer and begins to rummage around.

Gods.

He’s going to die.

And Chu Wanning doesn’t stop at big dildos either—the girths are big, around Mo Ran’s own size even—but he also has an assortment of colorful dragon and weirdly-shaped ones.

Mo Ran’s blood is running hot. He imagines Chu Wanning using this on himself, spread out in his bed, grunts escaping his lips as he forces the huge thing into himself.

Fuck.

Mo Ran’s underlying attraction to his professor is not a thing of new interest. In fact, as Mo Ran had started becoming closer to Chu Wanning, Mo Ran’s horniness levels have gone off the fucking rails. It’s so fucking annoying.

But also not really—because as he might have said before, Chu Wanning is the single most beautiful person to have walked the earth—and no, Mo Ran does not take criticism. How can he, when all Chu Wanning has to do to look nice is literally exist?

It doesn’t help that he’s exactly Mo Ran’s type. Lean and willowy, but also with enough muscle tone to hold himself upright. His hair is beautiful, and once Mo Ran had gotten the chance to touch it. He fucking swears that he’s never touched anything softer in his entire goddarn life.

And it doesn’t stop there, either.

Mo Ran has to wake on day to realize that he’s actually attracted to his professor on a more emotional, bone-deep level. That he likes Chu Wanning’s glares when Mo Ran makes a stupid joke or pun, that he likes how Chu Wanning sounds mean sometimes but he makes it up by patting Mo Ran on the shoulder and his eyes turning soft when he thinks Mo Ran isn’t watching.

So, yes, theoretically, Mo Ran is in deep shit.

However, it’s kinda hard to remember that when Mo Ran’s hand touches something soft and fluffy and he’s pulling out something from the back of the drawer—

Oh.

 Fuck.

He distantly wonders if this is how he’s going to die—of spontaneous combustion, holding a pair of cat ears and a cat tail buttplug, in the middle of his professor’s room.

At least it saves Chu Wanning from killing him himself, right, Mo Ran thinks, a touch bit hysterically.

But even with the threat of death on the horizon, Mo Ran can’t stop his stupidly curious brain from exploring further, because the next thing he knows, he’s also looking if the last drawer has anything like before—and. And there is.

Fuck.

There’s lingerie.

Most of them are white, which is Chu Wanning’s signature color, and Mo Ran brings some out to see—it’s so fucking sheer. If Chu Wanning were wearing this, Mo Ran thinks dazedly, no part of him would be hidden. Everything would be see-through, and no part of him would be hidden from Mo Ran’s view.

Fuck fuck fuck—

Fuck, he’s getting hard.

And when he looks just a little bit further, he sees something, nestled in between all the others, something with black lace. Curiosity piqued, Mo Ran picks it out and—

It’s a fucking pair of black lace panties, with little red bows at the sides.

Fuck.

Black and red are—very much Mo Ran’s colors. Chu Wanning couldn’t have not noticed this, because everything he wears to class has some aspect of red or black in it. The thought of Chu Wanning being dressed up in his colors makes Mo Ran’s blood sing.

‘Mo Ran? Why’re you taking so long—‘

Mo Ran’s head snaps up and then he’s staring right into Chu Wanning’s eyes, where he’s standing in the doorway.

Fuck.

And there’s no time to hide, and Mo Ran is left with awkwardly staring at his professor, while holding his professor’s lingerie in hand.

FUCK!

Mo Ran has to watch, frozen in fear, as Chu Wanning’s eyes take in stock of what’s happening, and then—and then his face entire shutters away.

All the progress that Mo Ran had been making to get closer to his professor, all the times he’d tried to make him show his softer side just a little bit more—all that, gone, just because Mo Ran couldn’t find some goddamn papers and decided to see if they were in any of the drawers.

And then Chu Wanning’s eyes shift to his face and Mo Ran fucking springs into action.

‘Laoshi, this isn’t what you think!’

‘Oh?’ Chu Wanning says, voice quiet. He suddenly looks…tired. ‘What is it then, Mo Ran?’

Mo Ran’s voice gets stuck in his throat.

‘It’s—‘ he says, but there’s literally no justifiable explanation for what he’d found. ‘Laoshi, I—‘

‘Leave, Mo Ran,’ Chu Wanning says, stepping into his room. Mo Ran goes still. ‘Get out of here. You have one semester left with me. I request that you change classes and get another professor.’

Mo Ran’s eyes are wide, and he can’t believe what he’s hearing.

‘Why?’ he hears himself say, and oh, that is so not the right thing to say.

Chu Wanning looks at him like Mo Ran’s a moron. Which he is. He just doesn’t know how that would apply to this situation.

‘Why?’ Chu Wanning repeats, looking angry, but then he loses all the fight in him, because his posture slumps, and he repeats, tiredly, ‘Leave, Mo Ran. I can’t deal with this on top of anything else.’

‘With—‘ Mo Ran says, ‘With what?’ Because something is wrong here. He doesn’t even know that he’s dropped the panties and moved towards Chu Wanning until the other flinches away.

Mo Ran’s heart hurts.

‘I don’t need you making fun of me,’ Chu Wanning snarls, ‘You think I don’t know the rumours? About how I fucked the headmaster to let me have this position? That despite everything I’ve worked for, everyone never thinks well of me?’

Mo Ran can’t speak.

‘I thought you were different. I thought you wouldn’t make fun of me, but in the end that’s all you’re here for,’ Chu Wanning snarls, and Mo Ran can see tiny tears beading at the corners of his eyes, and he feels his stomach swoop out from under him. It was him. He made Chu Wanning cry. ‘Now you can fucking laugh and make fun of me and get out of here.’

And Mo Ran lurches forward and glomps Chu Wanning.

‘Mo—Mo Ran!’ Chu Wanning says, voice slightly muffled in Mo Ran’s neck, and his hands are fisted in the front of Mo Ran’s shirt—he’s not pushing Mo Ran away, and that’s good, he thinks dizzily, ‘Mo Ran, what are you—!’

‘Laoshi,’ Mo Ran says, hugging him tight, so that Chu Wanning can’t escape his embrace, ‘Laoshi, please, listen to me.’

And Mo Ran can feel it when Chu Wanning goes boneless against his chest.

‘I—‘ Mo Ran gulps, because this is the moment of truth, if he fucks this up, Chu Wanning will never want to see him again—‘Laoshi, fuck—where do I even start? You’re beautiful and I love you and all those rumours are wrong, you know that? People say you’re an unfeeling person but you walked me home in the rain that one day and I was. I was just. I don’t know but I felt something, Laoshi, and then you were so nice and kind and helpful and I fucking fell in love with you? That’s so stupid, I know you think I’m immature and stupid and you’ll never want me, but still. You have to know this because I am different, and I appreciate you doing everything you can for me.’

By the end of rant, Mo Ran is panting, and Chu Wanning has entirely stiffened up in his arms.

And not the fun kind of stiff, either.

He waits for an answer, and he doesn’t dare to pull away. What if this is the one and only time he gets to hug Chu Wanning? Mo Ran can’t let him go, not just yet.

‘Mo Ran…’ Chu Wanning whispers, and his voice sounds so raw, so heartbroken, that Mo Ran finds his own heart breaking alongside it. ‘You don’t—you don’t mean that.’

And Mo Ran pulls back, just a little, to look at his professor in the eyes. ‘What, Laoshi? Which part don’t I mean? About loving you? Because that’s true. About you being kind and perfect and wonderful? Because that’s true too.’

Chu Wanning looks like he’s choking back a sob as he says, ‘I—I’m old, Mo Ran. You don’t want me.’

And still, Mo Ran persists stubbornly. ‘You look the same age as me, laoshi.’

‘I’m not a good person.’

‘You’re the kindest and most wonderful person I know,’ Mo Ran says truthfully, ‘You’ve been amazingly nice to me.’

Chu Wanning gulps, and looks away, eyes towards the floor. ‘I—I’m ugly.’

And Mo Ran finds that he can’t reply, because of how stupid that is. Does Chu Wanning really not see how beautiful, how pretty he is?

Chu Wanning, however, takes that as an agreement, because he renews his struggles, fighting to get away from Mo Ran. ‘Let—go!’

‘Laoshi,’ Mo Ran says desperately, ‘Laoshi, listen to me. You’re beautiful. You’re the most beautiful person I’ve ever met. I don’t know how you don’t see it, but if I have to live the rest of my life convincing you that you’re more beautiful than the stars themselves, I swear I’ll do it. And I’ll never get tired of telling you that you’re beautiful and deserve to be loved.’

And Chu Wanning is looking at him now, with teary eyes, and Mo Ran is but a man—how can he not raise his hands up to wipe them away, to free his professor’s face from all the hurt and burdens he’s been carrying by himself.

‘I’ll take care of you, Wanning,’ Mo Ran says quietly, and leans forward to lean his forehead against Chu Wanning’s.

Chu Wanning lowers his eyes, and whispers, ‘it’s rotten work.’

‘Not to me, baobei,’ Mo Ran says, the nickname coming to him easily, as easily as he traces his hand to cup Chu Wanning’s cheek and tilt his face up—‘not if it’s you.’

And Chu Wanning chokes on a gasp and throws himself forward and then he’s hugging Mo Ran, arms tight around his waist, and Mo Ran feels indescribable happiness bloom in his gut.

He doesn’t know how long they stay there, wrapped up in each other—only that he can feel Chu Wanning’s steady heartbeat against his chest, and that he knows that he never, ever, wants to let go.

‘Are you sure?’ Chu Wanning says softly, like he believes that Mo Ran will flee at any chance he’s been given.

Mo Ran, in return, grinds into Chu Wanning’s thigh, where he’s hard, again, because apparently, hugging his professor for an extended time is enough to make him pop a boner now. Gods, he feels like a prepubescent teenager again.

His professor gasps. ‘Mo—Ran?’ he asks, like he can’t believe what’s pressing up against his thigh.

‘This is what you do to me, baobei,’ Mo Ran purrs, ‘Look at what you do to me, hm? You make me hard, so hard. You make me want to fuck you into the sheets and watch as you writhe on my cock—and you’d take it easily, hm? I bet you can. I’ve seen what you kept in the drawer—I could slide into you so easily. Fuck, that’s so hot.’

‘Mo Ran,’ his professor says, and his voice is breathy, and again, Mo Ran turns his face up so they’re looking at each other.

‘Laoshi,’ Mo Ran says, ‘Can I kiss you?’

Chu Wanning looks disgruntled for a moment, and then he’s lurching up, kissing Mo Ran fully on the mouth.

It’s not a good kiss by any means—Chu Wanning is too rough and his teeth scrape Mo Ran’s lip, but just because it’s Chu Wanning, Mo Ran loves it, relishes in it, in the fact that his professor is kissing him, that his dreams have finally fucking come true.

‘Baobei,’ Mo Ran murmurs against his lips, eyes half lidded and hands sneaking to Chu Wanning’s lower back. He feels the other shudder against him.

‘Mo Ran,’ Chu Wanning returns, equally as sweet.

And Mo Ran is but a man—a man who is a slave to his desires, because he kisses Chu Wanning again, and again. His lust is insatiable, and he drinks in every sound Chu Wanning tries to muffle against his lips. He drinks Chu Wanning in like he’s going to go crazy if he doesn’t.

And because he doesn’t seem to be protesting, Mo Ran slides his hands down to cup Chu Wanning’s ass.

His professor honest-to-god fucking moans. Mo Ran’s dick twitches in the confines of his jeans.

‘Mo Ran,’ he whispers, and then a little ‘oh!’ as Mo Ran takes a hold of his ass and squeezes, and—fuck. Fuck Mo Ran can’t fucking wait to get his hands on Chu Wanning when they’re both bare, because Chu Wanning has an amazing ass.

Not that he didn’t know that before, of course, but it’s different when Mo Ran can see and when he can touch, because Chu Wanning’s ass is soft and plush and so fucking good to squeeze. Mo Ran thinks he might be in love.

When Chu Wanning bristles and growls out a reprimand, Mo Ran realizes that he might’ve said all out that out loud, but whatever. He doesn’t really mind Chu Wanning hearing his thoughts about him, either. The man needs to know how to be pampered.

‘Laoshi,’ Mo Ran says, where his lips are pressed up against Chu Wanning’s pulse point. His instincts are telling him to bite, to mark, to claim, and then when Mo Ran realizes that he doesn’t have anything stopping him, he does bite down—though a little bit more gently than he intends to, sucking marks onto Chu Wanning’s pale skin and relishing in the forming of bruises on his skin. It’ll be a sight to behold, that’s for sure.

‘Laoshi, do you think—how far do you want to take this,’ Mo Ran manages, when Chu Wanning gets his mouth on Mo Ran as well, pushing aside his ratty t-shirt and sucking on his collarbone—‘It’s fine—it’s fine if we stop here. I don’t mind. I want to—take it at your pace.’

It’s that that makes Chu Wanning pull back for a second, but before Mo Ran can swallow back his disappointment, Chu Wanning’s pulling him towards the bed—his bed!—in the room and pushing Mo Ran onto it—he goes, without much complaint. If it’s Chu Wanning, Mo Ran doesn’t think he’ll ever complain again.

And when they get onto the bed, Mo Ran clambers on and wastes no time in kissing Chu Wanning again, trying to memorize every inch of his skin with his mouth. Chu Wanning doesn’t seem averse to it—in fact, he leans into Mo Ran touch and goes pliant wherever he’s touching him.

‘Laoshi,’ Mo Ran says, tugging at Chu Wanning’s dress shirt—so formal, even when he’s in the house, Mo Ran thinks fondly—‘Can you take this off?’

‘Only if you take off…yours, as well,’ Chu Wanning says, a blush sitting high on his pale cheeks. He’s adorable.

‘Of course, baobei,’ Mo Ran says, and then he wastes no time in stripping himself of his shirt and flinging it away in some random direction. After, he gets to working at Chu Wanning’s clothes too, stripping him efficiently, until Chu Wanning is laid bare before him, a delight to his eyes, something for only him to see.

‘Oh, baobei, you’re so beautiful,’ Mo Ran murmurs, letting himself touch. His palms are flat against the plains of Chu Wanning’s stomach, of his sides, of his back—Mo Ran doesn’t think he’ll ever get tired of looking at Chu Wanning. ‘You’re so pretty too. Did you never notice me staring, in class? You were so beautiful. I love your hair, did you know that? It would be so good to pull on it when I fuck into you, I thought. Now I have you right in front of my and there’s so many things I want to do to you I don’t even know where to start.’

Breathless, Chu Wanning stares up at him, mouth half open, as Mo Ran traces praises and words of love into his skin, into his flesh so Chu Wanning won’t ever forget that he is loved, that he is wanted.

‘Mo—Mo Ran,’ Chu Wanning says, and then he’s pawing at Mo Ran’s pants, trying to get them off feebly, and Mo Ran, with a chuckle, removes both his jeans and underwear, and then he’s treated to the sight of Chu Wanning’s eyes going wide as he catches sight of Mo Ran’s cock.

‘Like what you see?’ Mo Ran teases, grinning as Chu Wanning flushes and looks away. He can’t help it—Chu Wanning makes it so unbearably easy to tease him. Gods, Mo Ran loves him so fucking much.

And then he leans in to kiss Chu Wanning again, pressing him back against the pillows and climbing over  Chu Wanning’s lap to straddle him and push their cocks together. Chu Wanning himself isn’t of a bad size, though he’s more lean than thick. But Mo Ran thinks, despite him preferring to top, he would very happily spread his legs for his professor if he ever wanted.

When he voices this thought to Chu Wanning, his professor looks aghast—‘Shameless!’

‘Oh?’ Mo Ran says, drawing a line up Chu Wanning’s cock with the tip of his finger, ‘But what we are already doing now is shameless, is it not?’

Chu Wanning doesn’t reply. Alright, maybe he deserved that. But that doesn’t mean he can’t tease just a little bit more.

‘Baobei, Wanning, laoshi,’ Mo Ran whispers, nudging Chu Wanning’s face with his own, until his professor looks him in the eye and leans forward to press a hesitant kiss to Mo Ran’s lips. He wants to squeal at how cute Chu Wanning is. ‘Do you think—what do you want to do? Please, tell me.’

Chu Wanning levels a look at Mo Ran that could be classified as a glare if he didn’t look so debauched, just from touching each other. ‘Don’t you know already,’ Chu Wanning says, snaps, but his voice is breathy because Mo Ran’s hands are smoothing over his hips, over his ass, getting his fill of squeezing.

‘I don’t,’ Mo Ran answers, just to be a little shit—‘or, does laoshi want me to guess? This one will do his best, but he doesn’t know—does laoshi want my fingers in his ass? Does he want me to finger him until he’s begging for my cock? Does he want me to use one of his toys on him—and see how far he can really stretch? Or—‘

‘Mo Ra—ah—uh!’

Mo Ran smirks. Chu Wanning cutting himself off because he’s trying to keep himself quiet as Mo Ran touches him is an image that’s Adorable, and Mo Ran’s absolutely making sure that he gets to see it again. His would life would be a waste if he didn’t.

‘Yes, laoshi?’ he says, in a sugar-sweet voice, ‘What were you saying?’

Chu Wanning glares at him. They both know that Mo Ran’s just faking it, but even so, Mo Ran gets the impression that Chu Wanning doesn’t truly mind.

‘Or!’ Mo Ran brightens up, as if he’s got the best idea ever, which he has—‘Or maybe laoshi would like to wear his cat tail and ears for me? Imagine how cute you’d look at me, baobei. I bet if you put on lingerie on top of that, you’ll look even more beautiful. You’d look so beautiful and I won’t be able to resist eating you right up.’

Chu Wanning’s cheeks grow darker at that, and Mo Ran knows that it’s not an idea Chu Wanning isn’t opposed to, but—‘Hm, Wanning? Would you like that?’

And Mo Ran watches as Chu Wanning nods slowly, and says, ‘next time,’ and he thinks that his heart’s going to explode out of his chest. Because this isn’t going to be a one-time thing. It’s going to continue, and Chu Wanning will one day dress up for him in lingerie and a cat tail.

Hell yeah.

‘Thank you, baobei,’ Mo Ran whispers.

Chu Wanning looks like he’s stopping himself short of rolling his eyes, but he drags Mo Ran down into a kiss anyways.

‘In the drawer,’ he says, murmuring against his lips, ‘There’s—there’s lube.’

Mo Ran perks right up and reaches over—it takes him only a few moments to locate it, but then he has a half-used bottle of lube triumphantly held up in the air.

Chu Wanning seems like he wants to say something, and then he stops. And then he starts. And stops again.

‘What is it, baobei,’ Mo Ran asks gently, leaning forward and kissing him softly. It’s returned, so at least Mo Ran hasn’t fucked up anything bad. He thinks. ‘Anything wrong?’

Chu Wanning shakes his head, and then turns to look at the drawer. That his sex toys are kept in.

Huh?

It takes Mo Ran a few seconds to register it, but then when he does, he very ungracefully blurts out, ‘you want me to use one of your dildos on you?’ and then winces sharply.

Chu Wanning glares at him sharply, but then he’s nodding and extricating himself from Mo Ran’s holding, turning around onto all fours so that he can reach for something inside. Mo Ran gets a very healthy, a very appreciative look at Chu Wanning’s plump ass.

When Chu Wanning settles back onto the bed, he’s holding a thick dildo—red in color, but it’s relatively close to an actual human cock. The fact that it’s almost as big as Mo Ran is nonwithstanding.

‘Here,’ Chu Wanning says, handing it to Mo Ran, and then he looks adorable flustered, floundering with how to position himself for this entire thing.

Mo Ran, taking pity on him, makes him lie on his back—because he’ll be fucking damned if he doesn’t get to see Chu Wanning’s face during this—and props his hips up with a pillow. And then he’s getting to work, letting the lube spread on his fingers and warming it up before holding it to his ass.

One last time, he looks at Chu Wanning for permission. And then his professor nods, Mo Ran sinks in, and it’s so smooth that Mo Ran wonders how often it is that Chu Wanning pleasures himself.

‘Two,’ Chu Wanning manages to say. His hands are clutched in the bedsheets. His knuckles are white already—Mo Ran wonders how Chu Wanning will react to his actual cock. He shakes his head. If he keeps thinking like that, Mo Ran’s sure to come early. And neither he nor Chu Wanning wants that.

‘Are you sure?’

‘Yes,’ Chu Wanning snaps, moving his hips just the tiniest bit—‘I’m used to it, just do it!’

And with a salacious grin, Mo Ran slides two fingers in smoothly and crooks his fingers upwards.

Chu Wanning arches off the bed, a scream muffled between his teeth as Mo Ran presses onto his prostate and holds his fingers there, not moving save for a few shifts around. Fuck.

Fuck, Chu Wanning is so pretty.

Mo Ran doesn’t hesitate to say it out loud either, watching as Chu Wanning turns his head away. What’s there to be bashful for, he thinks fondly, when Mo Ran is already two fingers inside him?

Two fingers that quickly turn into three, he might add.

Mo Ran watches as Chu Wanning clutches at the sheets, face scrunched up in an effort not to make any sounds.

Too bad Mo Ran IS Trying his damnedest to make Chu Wanning lose control.

Soon, he’s ready to take another finger, and Mo Ran thinks he’ll never forget the face Chu Wanning makes when Mo Ran slides four fingers into him.

‘Mo—Mo Ran!’ he cries out, and it’s like a heavenly symphony to Mo Ran’s ears.

‘Baobei,’ he returns, leaning over and kissing Chu Wanning softly, ‘You’re taking my fingers so well hmm? Look at you, all spread out for me. This student thanks laoshi for letting him see you like this!’

‘Mo Ran!’ Chu Wanning says, and his tone says that he’s supposed to sound enraged, but al his face shows is that he’s red and high on pleasure and barely paying attention to what Mo Ran is doing.

‘Laoshi,’ Mo Ran returns soon enough, spreading his fingers and feeling the tight wet heat of Chu Wanning around his fingers. He can’t fucking wait to get that inside him.

But first—

Chu Wanning gasps as Mo Ran slides his fingers out and starts drizzling a copious amount of lube onto the dildo—it wouldn’t do for Chu Wanning to be hurt, he thinks, even if his professor is used to taking things like this on a regular basis.

Chu Wanning’s eyes roll back in his head as Mo Ran starts to press the tip of the toy into him, and one of his hands come up to squeeze around Mo Ran’s bicep. He grins, and flexes a little. Just to show off.

But then Chu Wanning’s mouth is open in an absolutely sinful moan as the toy slides into him, controlled by Mo Ran, and he suddenly thinks; when Chu Wanning does this to himself, how had he done it? Does he have to bend far? Does he have to spend too much time opening himself up because surely Mo Ran’s fingers are thicker than his professor’s—does he grunt in arousal and annoyance when he can’t get it to reach his prostate?

‘Laoshi,’ Mo Ran murmurs, ‘Laoshi, one day, you have to show me how you do this to yourself. I wanna see. I wanna see you desperate and begging for it—I wanna see you begging me to fuck you because after I fuck you right now you’ll always want my cock, nothing else will ever satisfy you—‘

‘Mo Ran!’ Chu Wanning gasps out, and then he’s throwing his head back and whining as Mo Ran finally slides the toy all the way inside him.

Fuck.

Fuck—Mo Ran can see him stretched around the toy, can see him red and pulsing, the rim shiny from the lube. And the dildo is so fucking big, but Mo Ran still has a stray thought of forcing himself inside alongside the toy.

But that’s a thought for another day, because Chu Wanning is gasping, mouth opening and closing in little pants, and he looks—he already looks fucked out of his mind, and Mo Ran hasn’t even done anything yet. Fuck, is Wanning this sensitive?

‘Wanning,’ he murmurs, licking a stripe up his neck, ‘Wanning, are you okay? Can I move?’

It takes Chu Wanning a few moments to reply, but when he does, his voice is a snarl and he snaps out, ‘Fucking move, Mo Ran—‘ before his head falls back in a moan as Mo Ran presses down on the dildo so that it presses against his prostate, and this time, Chu Wanning can’t conceal the moan  that bubbles past his lips.

‘Oh?’ Mo Ran teases, drawing it out, just the tiniest bit, and then twisting his wrist to let it stir up Chu Wanning’s insides, ‘Who would’ve thought that laoshi would be so needy in bed?’

Wanning makes a frustrated sound, and then he’s dragging Mo Ran down to kiss him, and this time, their kiss is biting, rough, and Wanning bites down on Mo Ran’s lip hard enough that he can taste blood on himself. And all the while, Wanning’s trying to fuck himself on the dildo still held securely in Mo Ran’s hand.

‘Laoshi, look at you,’ Mo Ran says, letting a lazy smirk curl onto his face as he inches the dildo out, not in any rush to push it back inside, ‘So needy. Begging for cock—I wonder, will you beg this nicely once I’m inside you? Or would you want me to fill you up? Laoshi would look amazing filled up by me.’

‘Mo Ran,’ Wanning whimpers, and his hips buck up but Mo Ran follows the motion, keeping pleasure just out of Wanning’s reach so that the mix of pleasure-pain will be the best thing Wanning’s ever felt. ‘Mo Ran, please!’

‘Oh? What does laoshi want?’ Mo Ran pretends to think, not even bothering to hide the devious grin that comes across his face as Wanning whines and tries to push his hips onto the dildo. ‘You have to say it, laoshi, or I won’t know. Please guide this humble student?’

He thinks he hears a mumbled humble student, my ass but he can’t be sure, because in the next moment Wanning, at the peak of frustration, cries out—‘Mo Ran! Please! Please fuck me—please I need it please—just fuck me—!’

Mo Ran grins. ‘Now, was that so hard?’

And before Wanning can glare at him, Mo Ran uses the heel of his hand to push the dildo into Chu Wanning’s tightness, making the man scream as his entirely-untouched cock jerk and spit out ribbons of come.

Mo Ran has only a second to be surprised, because in the next, he’s using the weight of his hand to twist the toy inside Wanning, pressing into his prostate until he’s sure that Wanning will be sore and oversensitive, but the thing is that Wanning is still coming, crying out, one hand fisted in the sheets and another digging red welts into Mo Ran’s arm.

Fuck.

Fuck, that’s so hot.

And Mo Ran, ever daring, draws the toy out and starts fucking it into Wanning, punching out sharp little whimpers from him, and yet, even as his orgasm passes and oversensitivity surely must have hit him by now, Wanning is still gasping and shaking.

He still hasn’t asked Mo Ran to stop, and he even becomes concerned until Wanning’s body seizes and jerks up once and then he—his eyes are glassy and he looks like he’s coming again except there isn’t any come, except that his nails are claws on Mo Ran’s arm as he shakes and shudders one final time before collapsing, boneless, back onto the mattress.

Mo Ran stares at the mess Wanning’s made of himself, come on his torso, some even reaching his chest, and his face is seemingly in bliss, eyes closed and taking deep breaths as Mo Ran’s mind finally catches up to where they are not, now that his mind isn’t clouded by lust.

Fuck.

Wow.

That—that was something.

And now, Wanning’s looking up at him with soft, vulnerable eyes, as if after all that, he still expects Mo Ran to leave, to run away from that.

And Mo Ran can’t have that.

‘Wanning, baobei,’ he says, lying on the next, snuggled up beside Wanning—his own erection aches where it’s pressed against Wanning’s thigh, but that can come later—‘You did so well for me, baobei. You were perfect, you took it so well. I’m so proud of you.’

And Wanning, at that, lets his eyes slip shut and lets out a sound akin to a purr, and snuggles back closer to Mo Ran. They’re going to be a sticky mess after this, Mo Ran thinks, but he can’t really find it in himself to care, not right now.

Wanning, almost shyly, leans forward to peck Mo Ran on the lips, and then he seems to realize, because—because he’s drawing back and looking down, and—

‘You still haven’t. You still haven’t…that.’

Mo Ran hums in agreement, but his priority right now is to nuzzle into his professor’s neck, smelling the soft scent of haitang blossoms and something…minty, perhaps? Mo Ran likes it purely because it’s on Wanning.

‘It’s fine,’ he says, a little belatedly, when he realizes that Wanning is waiting for an answer. ‘I can take care of myself later.’

He opens his eyes and draws back just in time to see Wanning frown, but just as he opens his mouth to say something, Wanning is already moving, and Mo Ran’s lust-addled brain doesn’t catch onto what he’s doing until Wanning’s already spread his legs and his face is almost on top of Mo Ran’s very determined, very red, almost purple-looking cock.

Mo Ran gulps. ‘Wanning,’ he says, hand going out to card around Wanning’s head, smoothing it to the side—‘Wanning, you don’t have to do this if you don’t want to. It’s really fine.’

‘I want to,’ Wanning says stubbornly, but Mo Ran worries. Yes, Wanning might be adept in taking dick, but that doesn’t mean he’s experienced in sucking cock as well. And they both know that Mo Ran is more than well-endowed—he’s not bragging, it’s just a fact—and Mo Ran worries that Chu Wanning will bite off more than he can chew.

Hopefully very not literally. Mo Ran shudders at the thought.

‘Okay,’ he says, because Wanning’s got this look in his eye that says that he isn’t going to back down no matter what, but it’s also slightly dampened by the fact that his cheeks look to be permanently stained red. ‘But!’ he continues, ‘go slow, okay? I don’t want you to choke, or anything. It’s okay if you only get—the tip in. You can use your fingers for the rest of it.’

Wanning’s blush only gets worse by the time Mo Ran finishes speaking, and then he’s nodding his acquiescence before mouthing the head of Mo Ran’s dick.

It’s fucking amazing.

Even Mo Ran, with his limited vocabulary, feels like he should be writing about how warm and wet Wanning’s mouth is, how well he stretches around Mo Ran, and how he seems to know how to keep his teeth tucked under his lips so that he won’t hurt Mo Ran.

And he has this dizzying thought that he wouldn’t mind at all if Chu Wanning introduced just a little bit of teeth into the mix.

When Wanning’s had his fill of just giving kitten licks to his cock and laving the head with spit, he apparently decides that it’s time to actually try and suck Mo Ran’s cock, and—

Oh.

 Dear god.

Wanning’s already taken more than what Mo Ran expected him to, he thinks hysterically, and before Mo Ran can make any move to pull him off his cock, Wanning is already halfway down his cock, cheeks puffed out round his girth. The picture is unbearably hot. Mo Ran wants to sear the image to the back of his eyelids. He never wants to stop seeing it.

And it’s not like Chu Wanning isn’t going slow, but Mo Ran gets this primal, stupid urge to slam his hands on Wanning’s head and take, take as much as he wants, take his fill and leave Wanning a wrecked mess, so that his voice will come out bruised and raspy when he tries to talk.

He tamps down his desires, because he reminds himself firmly, he doesn’t want to hurt Wanning. It’s just that his pleasure is an all time high, and as Wanning sinks down by increments on his cock, the urge to give into pleasure and thrust recklessly into his mouth is seeming like more and more of a good idea.

‘Wanning,’ he manages to say, ‘Wanning—fuck—baobei—‘ hands clenching in the sheets—‘Fuck, you’re taking me so good fuckfuck fuck you’re taking me so well, your mouth is so good for me—fuck. Fuck Wanning your mouth—you’re so beautiful like this and I wanna—wanna fill you up with my come, come in you again and again until you’re round with it, until you have to use a plug to keep it all inside you—you’d look so pretty like that, wouldn’t you—‘

Chu Wanning moans around him, and gods that’s wonderful, the vibrations travelling up his throat and wrapping around Mo Ran’s cock. Wanning looks so pretty, lips stretched around his length—tears starting to bead at the corner of his eyes.

He looks truly helpless, and Mo Ran simultaneously wants to ruin him and hold him in his arms and keep him safe from the word forever.

‘Wanning,’ he manages at last, ‘Wanning, you can—you can get up. I wanna—I wanna come in you.’

And at that, Wanning makes this truly pathetic whimpering sound that makes Mo Ran want to ravage him.

Before long, Wanning’s sliding off, and he makes to clamber over Mo Ran’s legs, but he isn’t able to, because Mo Ran’s flipped him over easily, and Wanning ends up staring up at him with wide eyes as Mo Ran leans down and devours his lips. At least he isn’t unwilling—Wanning is pressing back like they’re solely dependent on the air they’re sharing between them.

‘Wanning,’ Mo Ran says softly, ‘Can I—?’

And this time, softened by his orgasm and mellowed out by the pleasure, Wanning is quick to nod, raising a hand to cup Mo Ran’s cheek and pull him down into a gentle kiss.

And when Mo Ran finally enters him, Wanning is heaven. His hole is tight and wet, despite having taken a toy earlier; Mo Ran groans into Wanning’s shoulder as he pushes himself in, as  Wanning makes little incomprehensible sounds that make Mo Ran go crazy.

And once he’s fully seated in his professor, Mo Ran lets out a low breath and bites down on Wanning’s shoulder. It’s actually an accident, he hadn’t meant to bite as hard as he did, but Wanning moans and clamps down on his cock, and—oh.

‘You like that, Wanning,’ Mo Ran says, because he is actually incapable of shutting up, ‘You like it when I bite? When I claim you, mark you as mine?’

And Wanning whimpers and nods and Mo Ran has to muffle a curse into Wanning’s shoulder not to come too early.

It isn’t long before he’s moving, because he can’t stay still, now when Wanning is squeezing around him so wonderfully. At first he tries to take it slow. He really does.

Except that Wanning hooks his ankles around Mo Ran’s waist and says, ‘faster’ and Mo Ran is but a slave to Wanning, so he gives in, hips snapping in and out of Wanning, who’s letting out the most delectable little sounds at each thrust.

Unknowingly, perhaps, Wanning’s fingers are curled into Mo Ran’s back, and it’s how he knows that he’s found Wanning’s prostate because those fingers dig in sharp and Mo Ran moans at the unexpected bolt of heat that shoots through him because of it.

‘Wanning, Wanning, baobei, laoshi, you’re so good for me,’ he babble, ‘You’re wonderful like this, taking me in so well—fuck!—ah, you’re doing so god for this student—I—I want this again, laoshi, I want to see you writhing on my cock and I want you to be mine. I don’t want you to be anyone else’s—fuck!’

‘Mo Ran,’ Wanning says, and his voice is breathy, punctuated by moans and whimpers as Mo Ran fucks into him, and—I’m yours, Mo Ran—uuh!—fuck—please, fuck, I’m yours—!’

And Mo Ran growls, thrusts increasing in frequency and strength and he’s hitting Wanning’s prostate dead-on every time, according to the strangled moans that leave Wanning’s mouth at in increasing frequency.

‘Baobei,’ Mo Ran pants, hands gripping Wanning’s hips hard enough to bruise, hard enough that he’ll leave marks and he’ll see them the next day and he’ll want to ruin Wanning all over again—‘Do you think—you can come for me? One more time, you can do it, right? Be a good boy and come for me, darling.’

And Wanning nods, so desperate, so eager to please, arching up to request for a kiss that Mo Ran willingly obliges him and then—

Then Wanning is coming with a scream, body pulsating and jerking and spasming as he comes untouched again and he clenches so hard around Mo Ran that it verges on the edge of being painful—

And then Mo Ran is following him over the edge too, letting out a loud curse as he tumbles over his pleasure, burying himself deep within Wanning as he comes.

He thinks he blacks out, a little, because the next thing he knows, he’s on his side and Wanning is softly caressing his face with one hand.

‘Mo Ran?’

He smiles softly, eyes half-lidded, and nuzzles Wanning’s neck. ‘Baobei,’ he says. ‘That was wonderful.’

Wanning makes a little noise, and Mo Ran pulls back to see the softest smile he’s ever seen on his professor’s face.

Mo Ran is content to stay just like that, forever cuddling with Wanning, and for a moment, he simply lets himself hold the love of his life—wow, that’s a new development?—for a few moments, basking in the afterglow of their…fun times together.

All too soon, though, Mo Ran’s made aware of the sticky come that’s drying on Wanning’s stomach and thighs. It takes almost too much effort to sit up, and it takes even more effort to make Wanning sit up and drag up to stand.

However, after soft cajoling, Wanning gives in and goes to stand up.

Except—except, it’s like his legs don’t work, because a second after Mo Ran lets him go, Wanning collapses onto the floor.

He doesn’t collapse entirely, of course, because Mo Ran’s there, but it still makes Mo Ran laugh in surprise as Wanning attempts to hit him and hide his face at the same time.

To think that Wanning can’t even walk anymore because of Mo Ran fucking him…he’d be lying if he said it doesn’t send pride and victory singing in his veins.

Wanning points him to the bathroom, and soon, Mo Ran’s settled him in the bath. Thank the gods Wanning owns a bathtub—Mo Ran doesn’t know how he’ll support the both of them if they have to stand in the shower.

Bathing is…surprisingly relaxing. Wanning is sleepy, that’s a given, but the soft vulnerability that comes with it is something Mo Ran wants to see every day—the force of Wanning smiling softly at him is still enough for Mo Ran to want to keel over because of the cuteness. He doesn’t think it’ll stop happening anytime soon.

And Wanning, despite his tiredness, insists on washing Mo Ran’s back. His fingers are lean and strong on Mo Ran’s back, and even he becomes drowsy, eyes drooping and only coming back to life when Wanning taps him on the shoulder to signify that he needs to get up.

After, Wanning gets them both fluffy towels. Mo Ran insists on drying Wanning for him, and he takes it with a small huff that could be classified as laughter. It doesn’t take long for them to be done, and in no time they’re heading back to Wanning’s bedroom.

Mo Ran catches his professor staring at his completely nude form. He at least makes a valiant attempt to pretend that he isn’t.

‘I don’t know if any of my clothes will fit you,’ Wanning says, after a few minutes of rooting around in his cupboard.

Mo Ran raises an eyebrow. ‘Are clothes really necessary?’ he asks, and is rewarded by Wanning spinning around and looking like he wants to reprimand him, except that he’s also blushing and his blush travels all the way from his cheekbones to his chest and damn that’s fucking cute.

He doesn’t quite know how he does it, but he does convince Wanning to come to bed with him and cuddle naked. It’s a win for both of them, obviously.

It doesn’t take long for them to get settled; Wanning slides into bed easily and Mo Ran follows after him, tucking the blankets around Wanning and himself so they’re comfortable and warm in their little cocoon.

‘Mo Ran,’ Wanning says, fingers twitching on where they’re laced with Mo Ran’s own.

‘Laoshi,’ he returns, just as easily, and then he tips his head forward just a little bit to kiss the curve of Wanning’s shoulder. Wanning is way too hot for his own right. Someone like him shouldn’t exist, but here he is, and Mo Ran is glad that he’s the one who got him.

‘If,’ Wanning says, eyes sliding away, ‘Do you…want to leave? After…after all this.’

Mo Ran suppresses a sigh. Of course, Wanning’s mind won’t rid itself of those thoughts that easily, but Mo Ran is trying, so he presses a kiss to Wanning’s forehead and murmurs, ‘I’m not going anywhere, baobei. You’re stuck with me, whether you like it or not.’

Wanning huffs a laugh against his neck, and Mo Ran can feel his whole posture untense in all the places they’re touching each other.

‘If laoshi wants more reassurance that this student will not leave him,’ Mo Ran starts slowly, keeping his head above Wanning’s to hide his grin, ‘this student could keep his cock inside you. Just to make sure I’m not going anywhere.’

The embarrassed noise Wanning makes is worth the way Mo Ran is almost kicked off the bed.
