Chapter Text
Knock, knock.
Lan Zhan's door is pushed open a crack.
"Professor Lan?" The "student" pokes his head in, eyes widening when they find Lan Zhan, who is grading papers at his desk.
Holding back a sigh, Lan Zhan pops the cap onto his red pen. "You may enter."
Wei Ying enters fully, his hand lingering on the doorknob. He has a book tucked under his arm, and his fingers subconsciously tighten around the spine. Shifting his weight from one foot to another, he seems to wait for Lan Zhan to break the silence. When Lan Zhan says nothing, Wei Ying crosses the office, holding the book, a reprint of Yugu Zhai Qinpu by Zhu Tongjun, out in offering.
"I brought back your book," he says awkwardly. His cheeks are faintly dusted with pink. Clearing his throat, he straightens his back and bows stiffly. "I'm sorry it wasn't returned sooner."
"You were supposed to bring it back a week ago," Lan Zhan reminds him archly.
Wei Ying grins, one hand scratching the back of his neck. "Well, one thing kinda led to another, and I had a lot of performance practice questions. I think you'll like the part I wrote about the different styles of—"
"You were supposed to bring it back a week ago," Lan Zhan repeats.
"I…"
Lan Zhan stands, and Wei Ying tenses as he approaches him. He barely brushes Wei Ying on his way to the bookshelf, where the book is easily slotted back into its place. He turns around very, very slowly, giving Wei Ying plenty of time to fidget in place. "Irresponsible."
Wei Ying's face crumples. "Yeah, I guess I am. But it won't happen again, I swear!"
"How can I give a positive recommendation for someone so careless?" Lan Zhan takes a step closer, one arm held behind his back. "You must conduct yourself more professionally if you wish to succeed in this program."
"It's…just a book," Wei Ying weakly tries to defend. "Is it really that big of a deal?"
Lan Zhan's gaze is as cold as frost, instantly making Wei Ying back down in fright. "How do you intend to prove you can be trusted?"
"What…" Wei Ying is breathing fast now, and his eyes are pleading when they once again connect with Lan Zhan's. "What do you want me to do?"
"Think for yourself."
"I… I guess I deserve detention?"
For the briefest instant, Lan Zhan breaks character. Wei Ying cracks as well, laughing. He hurries to scrub a hand over his face, getting back into the scene.
"Professor Lan…maybe there's…some other way. For me to…express my apologies."
"Mn?"
Taking a deep breath, Wei Ying reaches out, placing both shaking hands on Lan Zhan's chest. Lan Zhan goes rigid, but Wei Ying soldiers on, likely reasoning that it's too late to turn back now. His fingers toy with the top button of Lan Zhan's shirt, and when Lan Zhan does nothing to stop him, he unfastens it.
"Really?" Lan Zhan asks, the sneer evident in his voice. "You think you can avoid responsibility by—"
Wei Ying leans forward, shyly bringing their mouths together. When Lan Zhan doesn't immediately push him away, he winds his arms around Lan Zhan's shoulders, sighing into the kiss. His tongue dances across Lan Zhan's lower lip, but Lan Zhan does nothing to encourage him. After a few seconds of receiving no response, Wei Ying pulls away, rethinking his actions.
"Professor Lan…" Voice breathless, his face is flushed, and he slowly steps away from his unresponsive teacher. "I'm so sorry! I really thought that—ah!"
Lan Zhan grabs him roughly by the arm, yanking him in so that he can bite at his lips. Wei Ying loses his balance and trips, catching himself on Lan Zhan's chest, and, after a moment's hesitation, he begins to kiss Lan Zhan back with enthusiasm. The space between each kiss is filled with chatter.
"Professor, mmph! Pro…fessor Lan. Mm! Please… I'll do, mmph, anything you want. Just—"
A rough, strategic shove to Wei Ying's shoulders causes his knees to buckle. Lan Zhan winces at the sound of them hitting the floor. Arnica gel is a common feature of their aftercare routine, and he will make sure Wei Ying doesn't need to leave the couch for the rest of the day (for anything other than bathroom breaks and maybe another round of fucking). For now, however…
Wei Ying's eyes are somewhat glazed as he looks up from where he is kneeling, waiting for Lan Zhan to make a move. Stroking along his jaw, Lan Zhan lets the pad of his thumb swipe across Wei Ying's lower lip. His pink tongue darts out to chase after it, but Lan Zhan keeps it out of reach. At first, this makes Wei Ying pout, but his eyes follow the movement of Lan Zhan's hands as he releases the rest of the buttons of his shirt. Then, they widen as Lan Zhan unzips his fly and pulls out his cock. Wei Ying tries to reach it with his tongue, but Lan Zhan fists a hand in his hair, violently pulling him back. It is only when Wei Ying stops fighting him that Lan Zhan slackens his grip and allows him to take it in his mouth.
Wei Ying's entire form radiates smugness once he has his lips around Lan Zhan's dick. He slobbers and sucks happily, making all manner of lewd noises as he works, and he brings one hand up to wrap around the length he isn't quite able to fit in his mouth.
Lan Zhan swats it away. "Hands in your lap."
He receives an annoyed look in response, but Wei Ying does as instructed, folding his hands and resting them on his thighs. Lan Zhan holds onto his head with both hands and rocks his hips forward, making Wei Ying gag around it. His throat relaxes with each thrust until his nose is firmly pressed against Lan Zhan's body. Holding him there for a moment, Lan Zhan waits until Wei Ying begins to squirm before he finally lets him breathe. He inhales wetly, a line of saliva connecting his mouth and Lan Zhan's cock, and tears stream from his wide eyes.
"Have you learned your lesson yet?" Lan Zhan asks. Wei Ying fights against the hand cupping his jaw, forcing him to meet Lan Zhan's eye, but Lan Zhan holds him steady.
"I…yeah. I think I've—"
"I don't think you have," Lan Zhan interrupts.
Wei Ying sniffles. "But I—"
"Stand."
It takes a moment for the words to register, by which time, Lan Zhan is already hauling Wei Ying up to his feet. He spins Wei Ying around roughly, and a stack of papers is scattered when he half-falls onto the desk. Lan Zhan channels his annoyance at the mess into action, violently pulling down Wei Ying's pants. With a slightly more gentle touch, he runs his hand along the curve of Wei Ying's ass, then slowly drags a finger down the center.
He freezes when he feels moisture.
Wei Ying's tomato red face is buried in his arms. Straightening his back, Lan Zhan grabs him by the ponytail, forcing him to stand. "You planned this."
"N-no!" Wei Ying squirms, hissing when it causes his hair to be pulled. "I…didn't plan it. I just—"
"You did," Lan Zhan hisses between his teeth. "Did you you purposely keep my book longer than agreed upon?"
"Ungh! No!" He shudders as Lan Zhan drags his teeth across a shoulder. "I just—"
Lan Zhan bites down, and Wei Ying howls.
"Yes! I… I knew it would make you mad if I held onto it, and I…" His voice drops to a lower pitch. "I wanted to see what you would do."
Gathering some of the excess lubricant onto his fingers, Lan Zhan smears it along his cock before positioning it at Wei Ying's entrance. He doesn't push in yet, content with simply watching Wei Ying squirm. Without meaning to, he begins to count the seconds in his head.
One. Two.
Three.
Four.
"Ugh, Lan—Professor Lan!" Wei Ying complains, wiggling his hips. "If you're gonna punish me, just do it already!"
"It doesn't seem like it would be an effective punishment." Letting the head catch on Wei Ying's rim, Lan Zhan pulls back before Wei Ying can maneuver it in. "You are enjoying this too much."
"What?!" Wei Ying's ass bounces enticingly, but Lan Zhan doesn't cave. "I'm—I'm not enjoying this!"
"Well then…" Lan Zhan takes a step back. "No need to continue if you are not enjoying yourself."
"NO!" Wei Ying spins around and grabs both of Lan Zhan's wrists. "Pleasepleaseplease, I am enjoying myself! Please don't stop!"
Lan Zhan regards him with one eyebrow raised. "Then you are not learning your lesson."
Wei Ying groans. "What do you want from me? If I enjoy it, you stop; if I don't enjoy it you stop! What the heck am I supposed to do?!"
"Fair enough," Lan Zhan acquiesces. "Turn around and bend over."
Happily presenting himself, Wei Ying winks over his shoulder. "Professor Lan makes learning very enjoyable."
Lan Zhan does not dignify this with a response. Instead, he sheathes himself within Wei Ying, burrowing in until their thighs are flush against one another. At first, he pumps in and out Wei Ying slowly, giving him time to adjust (even if he doesn't deserve it), but his tempo accelerates little by little until he's eventually fucking Wei Ying with enough force to rock the desk. A pen he received as a birthday gift from his uncle rolls onto the floor. Lan Zhan barely even registers it because Wei Ying is loud and he never seems to exhaust his stream of consciousness ramblings.
"Oh fuck, Professor Lan. That's it, right there! Keep, ah! teaching me my lesson. I'll be good, I swear. Just take it easy on me, and we can talk this out!"
"Be quiet," Lan Zhan barks. "Anyone who walks by could hear you. Are you trying to get me fired?"
"Of course not!" Wei Ying nevertheless does nothing to hold back his moans and grunting.
"I said be quiet," hisses Lan Zhan. He shoves three fingers into Wei Ying's mouth, gagging him. Spit runs between his fingers, down onto his knuckles, and the mess makes him want to fuck this mouthy student even harder. Just to make him even more of a hot mess.
Wei Ying tries to keep speaking, but the words are muffled by Lan Zhan's hand. The blockage doesn't seem to deter him. In fact, he seems more determined to be as loud as possible while bent over Lan Zhan's desk, wailing and sobbing and moaning. His muscles begin to pulse around Lan Zhan's cock. His cries take on a sharper, desperate timbre, and he comes the instant Lan Zhan's free hand comes around to squeeze his cock.
As Wei Ying crumples, quietly whimpering, Lan Zhan allows himself to be greedy. He drives into Wei Ying with a force that must be painful given how sensitive he is post-orgasm, but Lan Zhan reasons that brats should be reminded of their place from time to time. And, in his opinion, Wei Ying has been let off the hook fairly easy. This lesson might need repeating.
His orgasm seems to appear out of nowhere. Hunched over Wei Ying's body, he's dimly aware that it must be difficult for Wei Ying to breathe with the full weight of Lan Zhan's torso resting on his. He braces his hands on the desk, pushing off of him as much as he can manage while his whole world is torn asunder.
Lan Zhan's chest heaves as he comes down from his high. Pushing Wei Ying's hair to one side, he kisses the back of his sweaty neck, and Wei Ying lets out a breathless laugh. "Holy fucking shit, Professor Lan. I think I've been railed straight into the afterlife."
A huff of laughter escapes through Lan Zhan's nose. He kisses Wei Ying's shoulder before pulling himself onto his feet. Rounding the desk, he opens a drawer to pull out the packet of wet wipes strategically planted beforehand. He offers a couple to Wei Ying, who wrinkles his nose as he reaches behind himself, and uses one on himself, getting rid of the excess fluids.
Wei Ying chatters all the while. "So, I'd count teacher/student as a success. Ooh! You know what we should do next? We should buy hanfu and dress up like a pair of cultivators from one of those wuxia shows!"
"Mn."
After they toss the wipes into the waste basket, Wei Ying drapes his arms around Lan Zhan's shoulders, kissing him sweetly. "I could be a bunny, and you could be a mean old wolf."
"I refuse to harm a rabbit," Lan Zhan says, narrowing his eyes.
Wei Ying laughs, kissing Lan Zhan again. "Fine, fine. You can be a bunny, and I'll be myself. And if you don't run away fast enough, I'll catch you and eat you!"
"Wei Ying!"
"Haha! Alright, you win. We'll figure out the details later. For now, let's just go out to the living room, and we can start season two of that one cake show you liked."
Lan Zhan steals a few more kisses before releasing Wei Ying, allowing himself to be led out of his home office. Hand in hand, they make their way down the hall, and Lan Zhan has barely sat down on the sectional before Wei Ying flings himself onto Lan Zhan's lap. Already holding the remote, Wei Ying finds the show he wants to watch, chattering on about "how cool would it be if we got proper supplies and started to bake our own cakes?!"
Squeezing Wei Ying's waist, Lan Zhan adds cake supplies to the mental list of things he will buy for Wei Ying as soon as possible. And unlike the silver ring, with inlaid sapphires and diamonds, resting in a velvet box tucked inside Lan Zhan's sock drawer since the second week they were officially together—he won't have to wait an arbitrary, socially determined amount of time to present these gifts.
