After Hours (Lee Dong Wook Professor AU Oneshot)

After Hours

(This was actually just a joke between moots but I had fun with it, just as a note I have NEVER written a y/n fic before with the 2nd person thing so sorry if it's a bit awkward lmao, trigger warning for sexual content obviously and it's a bit rough in parts just fyi, but it's all consensual)

**Please note: this is very NSFW. Like it is smut for the sake of smut. BDSM-lite. Be warned and take care of urself xoxo k thx 18+ and all**

You slump down at your desk, feeling defeated as you look at your email. Not again, you think to yourself. What is it going to take for him to recognize I actually know what I'm talking about? You sigh and think about all of the time and money you've put into your studies so far, going from the Bachelor and now to the Masters. Unfortunately for you, your previous thesis advisor quit, and they assigned you someone new... someone who just doesn't seem to be on the same page.

You draft a reply to the latest email from him:

Wednesday, 8:56pm

Dear Professor Lee,

I'm sorry to bother you late in the evening. There are only a few more weeks in the semester, and I really need to fine-tune my thesis before my presentation. We seem to have different ideas about how it should go. I know you don't normally do office hours on Thursdays, but would it be possible for us to meet?  I'd really appreciate it.

Thank you,

Y/N Y/LN

Professor Lee is a transfer from another university, and while he is well-known in [your favourite subject], you just haven't been able to to get him to understand your point. Every time you send him drafts to revise, they come back heavily edited, with so many comments and cross-outs that you can barely recognize it as your own work. You've been busy and so has he, so you haven't been able to meet in person for a while, but you really need to. 

Your email pings. You open it and read the reply, which came almost immediately:

Wednesday, 9:00pm

Y/N,

I don't have a lot of time this week because I need to supervise the final exams for the undergrads. Are you on campus right now? Come to my office if you really need to. I'm in room 304 in the [your favourite subject] main building for the next half hour or so. Please knock first.

-Dr. Lee

You check the time on your phone. Now? So damn late... but thankfully you and your roommates have a place just five minutes from campus. You look down at your casual outfit and shrug. It doesn't matter I guess. I won't be there long.

You make the short walk over to the campus and pass by a few people you know. Some of them try to chat with you, but you have to apologize and keep going. Who knows when Professor Lee will be free to meet again? You need to see him now.  Besides, it's freezing outside, and you need to get warm again immediately.

You make it to the main building and get into the elevator to the 3rd floor. As the doors close, you start to feel a bit nervous. You've met with him alone a few times, but always in the day, and it was months ago. This time the building is quiet. When the elevator door opens, only a lone custodian is making his rounds. No other professors seem to be still on campus.

Room 304 is down at the end of the hall, with nothing but the number on the door. You swallow hard and then knock lightly.

"Yes?" comes a low, melodic voice from the other side.

"It's me, Y/N," you confirm.

"Ah, okay. Come in."

You open the door slowly. The professor's office is a mess, with books piled up on every available surface, as well as the shelves behind him. Several Starbucks cups are stacked on the desk and you can spot many more in the overflowing trash can. The professor is in front of his laptop, barely having looked up at you as you walked in. A hastily scribbled sign on the desk says Dr. Lee Dong Wook, PhD.
