“You know what, forget it, I’ll just drop the class.” You say dejectively, grabbing your black worn out blue jansport backpack and moving to the door.
“You do that and you won’t graduate on time!” The Professor raises her voice at you and you not even your leather jacket isn’t thick enough to shield you from that truth.
You falter in step to turn back to her.
“So you won’t allow me to switch, you hate me from the last semester-“
Professor holds and hand up to your tantrum.
“I have never hated a student.” She says an air of authority about her.
You laugh rudely in her face.
“You sure have a funny way of showing your devotion to your students!” You yell now, not caring about how petulant you are acting.
“I’ll remind you that your in my office hours, and you can low level your voice and change that attitude real quick.” Professor Harkness face morphs to one you’ve yet to be at the end of. But had scene enough through your school year.
“Ya know what, why don’t we skip to the end, just fail me- you know you-“
You start to yell again and then Harknesoses her own temper.
“I have never given you a grade below a B minus!” The older professor defends like you’re being a flat out moronic.
“Yeah, except you’ve given the harshes feedback and blacklisted me from being a teachers aid to anyone here! You’ve not approved of a single internship I’ve tried for graduation! What is your problem?” You can’t believe your own insolence but you won’t stop now.
Some people would have blamed it on a certain hormone therapy you were working through. But you wouldn’t agree, Professor Harkness had been a terror on the student body. What’s worse is that you had liked her in the beginning, and something had changed.
The ugly voice inside of you said that it was you who had in fact changed…
That that was the reason for her coldness to you…
“You had no problem with my workload last semester, and I told you the teachers assistant position in this department was full, but I would make room for you - if you wanted to do my first years. I do not see how I’m some evil witch, it’s like I’m just missing the pointy hat with you!” Harkness breaks her normally solid composure to yell back and you just don’t want to do this anymore.
You sigh and look down at your shoes.
Her warm light in this old office is so inviting, you think back to before you transitioned, when you’d stumbled in here asking for a reading list, four years sure changes things.
You push your glasses up your nose and look at her with a new confidence that, that young girl lacked.
“I will be dropping the class, I’ll not finish if that’s what it takes. But I’m not going to be here another semester where you pick me out of a crowd just because you can.” You grind out, thinning of how often she’d called upon you with no reason.
Harkness eyes widen a little, her lips move to say something but your twisting back and you grab the doorknob.
It’s such bummer your such a noob, because that would have really been a great moment to storm out.
But as you wiggle the doorknob, you’re struck with panic at this being even more awkward.
Harkness doesn’t say anything as you twist it left and right and it doesn’t budge.
But as you use brute force you hear a pin drop in the lock.
“Fuck - you’ve got to be kidding me.” You scorn at the metal handle. “Who even has these fancy ass hold metal doorknobs anymore, fucking pretencious piece of shit!”
You kick the bottom of the door and Harkness takes a forced breath and then comes around to you.
You step back and avoid eye contact.
Harkness tries to lift the doorknob carefully but it’s no use.
“Yeah no I know how doorknobs work.” You spit back and Harkness groans, her own panic starting to build.
“You can’t call the janitor?” You point to the landline on her desk, walking over you lift it to hear no dial tone. You feel a new fear.
“You’re born in the 90’s, you don’t have a cellphone on you? Isn’t your generation glued to it?” Harkness bites back, and you pull it out to show it’s absolutely dead.
“Okay Professor, you’re not ninety, don’t you have a cellphone?” You bite back and Harkness hangs her head and puts both hands in her hair.
“Yes I do, out in the classroom with my bag, you all but argued your way into my office hours. I didn’t grab it while we were mid argument.” Harkness round the desk to her computer, you drop your bookbag and open your laptop.
“You’re joking, you have to have wifi in here right?” You challenge back and Harkness takes off her glasses and pinches the bridge of her nose.
“It’ll be down until tomorrow,” she grabs the flyer for tech outages that each professor got on their desks this morning. You pinch it out of her hands to look at the times.
“Nine am? People have class before that! I can’t be here until nine am!” Your panic only builds and the Professor eyes you carefully.
“You don’t have some girlfriend or roommate or something that will come looking for you?” She asks, and you don’t hear the intrest in her voice, you’re too busy thinking of how you’re going to die in this fucking room.
You’ve never yelled at anyone like you just had and now karma thought it would be super duper funny to have you sit in the mess you’d made.
“No, no I don’t. Why don’t you have somebody at home waiting for you?” You spit back, imagining some boring guy who’s taller than you with a law degree and a kombucha project.
“No, I live alone, well I have a rabbit but he’s got enough food for the next two days.” Harkness adds then she starts to laugh at the absurdity of it all.
“Hey don’t crack up on me, this isn’t funny!” You yell back and she shakes her head and then wipes at her eyes.
“No, it is though. When you think about it, it’s actually hilarious.” She says and you put your laptop back in your bag, moving around her desk looking for an iphone cord.
Only for Harkness to giggle harder, then start to snort.
“I’m an android user.” She keeps laughing and you’re struck for the millionth time with the thought that Professor Harkness is gorgeous.
You awkwardly go back to her expensive looking leather sofa.
Sitting down on it you don’t say a word, and then Professor Harkness stops laughing all together.
“What are you doing?” She arches an eyebrow now.
“Well I’m not spiderman so I can’t crawl through the vent.” You snarl back and that shuts your professor up.
First Hour
It’s dead silent, you end up laying on her sofa, your feet over the edge of leather.
You pull out a book and start reading it, not wanting to sit in uncomfortable silence.
But Harkness is sitting at her desk, grading papers the old fashion way with a red marker.
But she keeps looking up at you like she wants to say something, then stops herself.
“Fuck, what is it?” You finally say putting the book on your chest.
The office had no windows, you only could tell that time was passing by the old dark academy looking clock in her dark wooden office.
But god you couldn’t concentrate on your book at all.
“You really think I hate you?” Harkness asks, you twist to stare at her, wondering when she’d ever looked this soft.
Blush worn from the day, her black turtleneck and glasses just made her look so…no - you wouldn’t go there.
“Let’s just not talk, okay? As soon as we get someone to help us, I’m not your problem anymore.” You lift your book back up and miss the small flinch in those dark eyebrows of the older woman.
You read maybe two lines before she interrupts again, not bothering capping her red pen as she ignores her work.
“You wouldn’t happen to have a sandwich in that bag of yours? Greek salad and a shirley temple?” The professor breaks the silence to ask.
You don’t react for a second, before you sit up, tossing your legs to the ground to open your backpack.
You open the loud war torned zipper and your Testosterone bottle accidentally stumbles out, moving under her desk.
“Shit,” you curse, but the professor is already pushing her chair back and bending down to grab the little glass vile.
She looks at it with interest before handing it back to you.
“You don’t carry the needles around do you? Do you need an injection soon?” She asked as though you would magically transform back if you didn’t get it right now. You laughed a little at her.
“I’ll be okay, unless no one breaks us out for two weeks, then we’re gonna have to get creative.” You joke, forgetting you hated the older woman, as you dropped it back into your bag then riffled around in your disorganized bag.
“Men,” Harkness smirks seeing how you had no folders for your papers. You don’t hear her, as you reach in and pull out a protein bar and a packet of gushers.
“Your choice,” you offered them both and she eyed the gushers like they’d personally offended her.
“How old are these?” Harkness asks and you glare at her.
“Oh I’m sorry, and what did you bring to the picnic?” You can’t believe that Harkness actually shrugs and picks up the protein bar.
Opening the package and snapping it in half and handing it to you first.
You don’t understand until she explains.
“Dinnner, that’ll be dessert. Or breakfast depending on how long we’re going to be locked in here.” She says simply and you take the other half.
You lay back down, nibbling on your dinner and not looking back at the wicked professor.
Who for sure didn’t look adorable while taking off her heels and sitting back at her desk.
Hour three
You were dying, it was fucking sweltering in her office. The sweat was trickling down your back and you were trying to ignore it with your book.
But when Harkness stands up and lifts her turtleneck up off her body your eyes snap over at the show.
The little bit of skin showing from her stomach as she takes off the black thick material.
Only for her to pull down a white t shirt she’d worn underneath.
You don’t look at her breasts, you wouldn’t do that, you look at your book with intensity.
“You can take off your shoes and jacket, you must be boiling in it.” Harkness tells you, like an adult who can stand being in a room with someone who was rude to her.
Not like you, who was in fact boiling from the inside out because of all the tension.
“I’m fine.” You say back, but your voice waivers just enough.
“Suit yourself.” Harkness say back a little quieter then before. Almost miffed at you, but she’s not her usual brutal self.
You swallow then set the book down, staring up at the ceiling.
“Have you gotten to the good stuff yet?” Professor asks and you turn and can’t help but smile.
“You read smutty novels?” You say too excited at such a fun fact.
“That’s the third of the series, you aren’t even to the good stuff yet.” Harkness answers and caps her red pen and flips an essay over.
“Wow, who would have thought, Professor Hardass!” You laugh and the older womans face drops.
You regret it immediately, the way her shoulders stiffen and her expression turns icy.
You are a little ashamed you’ve done this to her.
You both are quiet again.
Hour Five
You stand up abruptly and take off your leather jacket, embarrassed that you were wearing a tank top underneath it. But whatever, it’s a crop too, just to your belt line. It’s one of those old school punk bands that you’d made the cuts too.
You sit back down and push off both your shoes to your white socks in the space and you sigh a little.
You miss the way the professor is staring at your muscles like a woman starved of the flesh. The way she notices the bulge in your shoulders now, not like two years ago when you’d first taken the shot.
No, you’d been hitting the gym hard, the way your arms look a little wet from sweat doesn’t help the way Harkness feels.
She bite her cheek and looks back at the essays, but your hands shake, she cannot possibly read it now.
Hour Six
“You didn’t start to pick on me like that…..when…” You say out of the blue and Harkness is staring at you - waiting for you to finish it.
“Nevermind.” You say anxiously, looking down at your hands.
“You think I don’t enjoy you in my class because your trans?” She asks completely confused at you, your bottom lip shakes but you twist to look at her over her desk.
“Well?” Your tone is angry, because if one thing you’d learned from Testosterone.
Anger was easier than all of the other feelings, anger made you run faster at the gym.
It made you less of a cry baby like your dad had always said.
Anger was so manly….and maybe it was.
But why did it make you feel so damn sad.
Like you were constipated emotionally and the only emotion that was within reach was this…anger.
Your knuckles were white as you squeezed your hand hard again. Then let go, seeing how your fingers were dark red from the pressure.
“You know I’m the one who made them change all the names on your paperwork.” Harkness said gently and you looked at her with more confusion.
“I didn’t know that, no. I assumed but…thank you.” You respond and Harknes nods once and then licks her bottom lip.
“I did tell them to not take you as a TA. I didn’t let anyone take you on, and…I blocked your ability to get an internship.” Harkness reasons again and your frustration turns to pain in your face and as she looks up to keep speaking she loses her nerve.
“Why would you do that?” It’s so fucked up. Because I-I’m not worth the program or?” You gulp, your new adams apple bobs and Harkness watches it, watches the way your neck moves.
How you needed a shave around your throat, now the sweat has the ends of the back of your hair just a little wet.
Professor Harkness works so hard, every god damn day.
“I-” She starts again and you scrunch your face up.
“Let’s go back to not talking, it’s fine.”
Hour Seven
You wish you could sleep, but as Professor turns the lights down, it’s only about 5pm. There was not a chance in hell on a goodday you could sleep.
You look over at the Professor with her dark hair, glasses on her nose, casual white t leaning back in her chair with her feet on her desk.
A sight you never thought you’d get to see.
But you study her as she breathes evenly, a bit of sweat dripping down to her collarbone, you try to see if you can see what color bra she’s wearing.
She jerks her knee to scratch it and you flinch as though you’ve been caught.
Making her eyes open, and look at you.
Caught.
“Not tired after our big meal?” She teases and you actually hate how funny she is.
“You didn’t like the red gusher?” You counter back and feel as though it’s coming off maybe too flirtatious.
The Professor closes her eyes again and makes a pretend disinterested face, scrunched her nose up.
“The blue was better,” the older woman answers as though they were fine wines you two had tasted.
“Pretty sure that’s the blue food coloring over the red. But I promise you the red food dye has a certain buzz.” You flitter your fingers near your head and she laughs again at your joke.
You don’t remember the last time you’d heard such a full body laugh.
It makes you smile despite yourself.
You both sit for a moment and you think maybe she’s trying to sleep again.
“What do you normally do at five pm as a senior college student in this town? Besides reading vampire smut?” The Professor was definitely sounding flirtatious now, right?
“I don’t have any friends Professor. I mean, I work sometimes at an animal shelter. I made another bro friend, sometimes we go running. I like…live music. Good beer, long walks on the beach…” You smirk at the end and you don’t turn and see a similar look.
“Wow, a leather jacket wearing softie.” Harkness teases back and you think she’s actually pretty right.
“It’s not my jacket..I mean it is now, but it wasn’t always…” You trail off and think of a fallen friend.
“I’m sorry.” The Professor responds, evidently you weren’t as guarded as you’d like to think.
“Thank you.” You say for the second time in this tight space.
You listen to her breathe for a few seconds, finding comfort in the melodious way she is in her space.
Until your surprised by more questions.
“Why can’t you sleep, afraid the wicked witch teacher will suck our your soul?” Harkness self depricating doesn’t feel on brand and you don’t like it.
You can’t look her in the eyes but your man enough to apologize when you’re an asshole. So you speak it with your eyes closed, finding the safety in the dark.
“I shouldn’t have called you that nickname…I guess I just thought if I made you the villain…I could quit all of this… i thought maybe you calling on me all the time, being such a hard professor…I don’t know.” You trail off finding your own apology actual dog shit.
Harknesss throws you off by being far wiser than you.
“Why are you running away? You’re so close to your degree?” It seemed like the professor was genuinely devastated by the idea.
You keep your eyes shut so you don’t see the pity.
“I transitioned in this town, I go into every room and I’m not…just another guy…I’m that trans guy. I guess i just thought if I could run away from it all..Maybe someone would see me, I guess that’s stupid to hear from someone liike you.” You say and then you have to turn and look at her, but you hadn’t heard her move closer to you.
That she’d pulled the chair around and was a mere foot away from you.
“Oh shit, I didn’t realize I was on the clock.” You joked seeing you laying on the sofa and her sitting up looking at you with kindness saved for a loved one.
Not a random student with an identity problem and a vile of confidence in his backpack.
But the way her gaze hits your bones makes the joke land flat.
“You are so handsome, so intelligent, you have the whole world in front of you. Finish your degree, please? You worked so hard, and I-I will stop being so god damn selfish and-”
You don’t understand and you furrow your brows at her.
“You aren’t selfish, I mean you’re no easy A. But you-”
“I picked on you in my class, I treated you different because I was having my own…midlife crisis?” Harkness tries the word out like she’s been trying to figure it out herself.
She looks up like she can’t figure out how to do this.
As you watched her, you noticed how human she was now, in the heat of this tiny space, in her glasses, in this warm glow.
“I don’t understand.” You say honestly, still not putting the pieces together.
Your professor takes a long inhale for confidence and you wonder how someone so brilliant can be so unsure.
“I treated you different, I punished you so it would punish myself. I’m not supposed to fall for a student, I could lose my job.” Professor says it all at once, almost like she’s a school girl again.
Your heart was beating in your ears.
You don’t say a word, but as you stare into her baby blue eyes you are sure this is another dirty dream.
Those wet ones where you wake up hornier than hell, stupid hormones.
This can’t be real.
Professor Harkness can’t be sitting on her desk rollie chair in front of you in her barefeet and heat blush.
Telling you she….
“Fall?” You repeat the word back, like this is a vocabulary test.
“Yes, I stopped you because if I could still see you everyday- If you were in my class…If I didn’t show favoritism, if I was hard on you - no one would know. Fuck, I had no intention of you finding out this way or-I mean.”
You cut her off by sitting up and starting at her harder.
“I’m trans though?” You say and you see Harkness heart break.
“Sweet boy, I know that. Remember I’ve been here the full four years in the same classroom as you.” She smiles warmly, a look you found yourself intoxicated by.
Was that possible, to dissolve with the curl of a womans lips like this?
“I-I don’t have a dick, you’re I mean you-” You babble like an idiot.
You stand up and Harkness pulls her chair back a little so you can pace back and forth.
You wipe at your forehead with your hand anxiously moving the sweat.
“Sweetheart, are you okay?” Harkness softness is so good you want to lick it up her thighs.
“You don’t hate me.” You repeat feeling suddenly claustrophobic in the space. Was this how love hit people, like a mactruck to the ribs?
“No, I never did. You just, caught me off guard and I-I’ve never been-”
Your internalized transphobia sparks and you look at her with big sad eyes.
“With a transman,” you interject but her gentleness takes the air out of your lungs.
“With a student.” Your professor responds and your mouth makes a small ‘o’.
You feel naked in front of her now.
“But no, I’ve never been with a transman….I’ve always loved the person not the gender…” Mrs. Harkness looks at you like she’s not sure if you will combust.
“I don’t think I understand still, what- how?” You just keep looking down at your white socks, your brain short circuting.
Your Professor stands up and comes to face you, her fingers lift your chin, the bit of hair there soft against her.
You are eye to eye now and she hesitates.
“I’m going to try to teach it to you the best way I can, okay?” Her breath smells like blue gusher and something so yummy you couldn’t have possibly envisioned it when you masturbated to the idea of this.
“Yes please Professor.” You stumble like a boy in love and her grin makes your knees buckle.
But she moves just centimeters from your lips.
You can feel them ghosting against yours.
“You’re going to have to call me Agatha.” She says and you close your eyes just as her lips meet yours.
You kiss her like it might be your last kiss. You grab at the back of her neck and she moans at the intensity of you.
But you couldn’t hold back if you wanted to, you never imagined a pretty woman would ask you to call her by her first name, you fought to be a man worth kissing.
And now here she was, and you would’t disappoint.
Your Professor moans again as your tongue teases at her bottom lip. She’s pushing you back so that you fall onto the leather sofa, and she’s on your lap, straddling you.
Her stocking covered feet hanging off the side of the sofa as her knees fall to either side of your thighs.
She sits on you and you thrust up, your clit wanitng to push against her - but it doesn’t know it lacks length.
You kiss her open mouthed and the moan she makes this time has your body on fire.
This was so much better than anger, or alone in your room with a vampire book.
Agatha grabs at the back of your hair and tugs so that you can’t keep devouring her.
“Easy sweet boy, what’s your rush? We have time,” She brushes her lips against you and as you try to surge up she lifts off just a bit. It’s a promise for more than just this room and your heart swells.
“You are too good to be true.” You say with big adoring eyes up at her.
She laughs and kisses you gently, and you’re not sure how to love like this.
But you’re sure that Agatha could teach you.
Epilogue
When the locksmith comes to unlock the door, you and Agatha are laying on the worn sofa fast asleep. You’re wearing just your boxers and she’s naked on top of you, your leather jacket draped over her lower back.
The old man just smirks and closes the door again, leaving a key on her desk.
