When your eyes grow tired from staring at your laptop's screen, you peek above the edge of the monitor to get a glimpse of Frank. He's working on his desk, tucked in the corner of his living room by the window, while you lounge on his couch going over your assignment once more.

Frank doesn’t usually invite you home during week days, but today he’s made an exception. You don’t get to see each other as often now that the end of the final semester approaches, so he’s agreed to have you over a couple of nights a week out of your usual weekend visits. It’s nice to see him like this, even though you have to get up earlier to get to campus in the morning, it’s worth it. You’re not sure yet how much you’ll be able to see him during summer so you have to take any chance you can get to be with him for a little longer.

His sharp focus is on the stack of papers he's grading. There's nothing that can disrupt his concentration. Not even the loud noises from the construction site across the street bothers him. That kind of discipline must be something he took from his marine days, you’ve gathered. There’s only one thing that could make him lose that determination and that weapon is you. You’ve learned to wield it wisely, though he still tries to resist it sometimes.

Unlike him, you're easily distracted and find yourself half the time watching him instead of working on your paper. Your mind is quick to forget about anything that doesn't involve picturing Frank bending you over his desk and giving you a good pounding. Not even Mr. Clean could get rid of the filthiest thoughts that rouse when he rolls his sleeve, baring the tout veins of his forearms. This is probably the only downside of being near him, all you want to do is fuck, cause you barely get the chance anymore. But you're trying to control that impulse cause you want him to see that this relationship is more than fucking for you, which is it. That doesn't mean that you desire him less. Au contraire. Ever since you told each other I love you, it's made you want him even more. And the secrecy of it all makes it a hundred times hotter.

It’s a miracle you've made it past the two-hour mark without touching him when all you’ve been thinking about since you got here is jumping his bones since you got here.

You quickly go over your paper one last time and when your eyes finally refuse to go back to it, like a moth to a flame, you quietly bat your wings and stand up from the couch.

You try to pad quietly in his direction but one of the floorboards creaks, giving you away.

“Sh, don’t even think about it. Sit back down.” He warns without looking at you. “I told you I had a lot of work to do today.”

“What? I was just going to get a soda.” Changing the course of your steps to mask your intentions, you head to the kitchen to grab a drink from the fridge.

Well-aware of your tactics, Frank scoffs and briefly gazes at you as you take a long sip of your coke. He fixes his glasses on the bridge of his nose, and twirls the pen between his fingers before bringing his mind back to his task.

“I thought your TA was supposed to help you with those.” You lean on the arm of the couch.

“He’s sick.”

“C’mon. Take a break. It’s not like they’re due tomorrow, are they?”

“No, but I like having a head start. And it’s Tuesday, this is what I do on Tuesdays.”

He's a creature of habit, and you love that about him. But sometimes it's fun to mess with him and see if you can get him to lower his defenses enough to break his patterns. You usually get your way in the morning when his alarm goes off. You just wrap yourself around him and beg him to stay a few more minutes cuddling with you. Being the weakness of a man of his magnitude is something to be proud of.

“It's good to change your habits once in a while, you know?”

“You being here is already a pretty significant change in my habits, don't you think?”

“I guess it is.”

“So what's the problem, sweetheart?”

“Nothing. I just… I can't concentrate anymore.” You rub your thumb and index on your eyes. “I think I’m getting a tension headache.”

“Well, you should go see a doctor.”

You take another swallow of your drink and place the can down. Then, you bite your lip and go back to your initial plan. You get down to your knees and crawl the short distance to Frank's desk and place your head on his thigh, staring up at him.

“Please. I wanna play, Professor.” Your begging is only mildly annoying to him.

“You're being a fucking brat today, you know that?”

You can see his brow knitting behind the frame of his glasses, but you don’t back down.

“What are you gonna do about it?”

“I'm gonna let you sit there on your knees. See how long you can last once they start hurting.”

“So you do have a thing for punishment. Is that why they called you the punisher in the marines?”

“You don’t wanna find out.” His lips curve up ever so playfully into a grin.

Oh, but I do wanna find out.

Instead of saying that, you open your mouth and take a bite of his thigh over his pants.

“Jesus Christ, what's gotten into you today? Why are you so needy?” He almost jumps out of his chair when you clamp your teeth harder over the fabric.

“I'm needy cause I want you, Frank. Don't you want me back?” Your palm slides up his thigh, but Frank quickly catches it before it goes up too far up his groin.

“Of course I want you, sweetheart. More than anything in the world. But I gotta finish here first. Can you wait until I'm done?”

“You just want me to beg, don't you? Please? I'll do whatever you want. Would you let me?”

Your relentless pleads drag your lips farther up his leg. You're aware you're pushing his buttons more than you should, but there are times that you can't really help yourself, like now.

“Sweetheart…”

Frank huffs low, losing energy by the second to deny you. His chair finally swivels a few degrees so he’s facing. He puts his pen down and stares at you, letting you supplicate some more.

“Please. Let me be your DA.”

“You wanna be my TA?”

“No. I said D—A,” you accentuate the D. “As in your dick assistant.”

“You're out of your mind.” He laughs, shaking his head.

“I'm just crazy for you,” you sigh, pillowing your cheek on his thigh again.

“God, don't look at me like that. You know I can't say no to that face.”

“Please,” you repeat, batting your lashes. “Let me take care of you, Professor.”

“You're going to be the end of me,” Frank says, defeated by your perseverance.

“I know.”

“Have you finished your paper?”

“I have.”

He drags a hand down his chin, accepting that he cannot ever resist you or say no to you for that matter.

“Okay, go ahead, sweetheart.”

As he hangs his head back for a beat, you straighten up and sit on your haunches, sending both your hands to undo his belt and fly.

Frank takes off his glasses, puts them down on the desk, and rubs his fingers on his eyes as you palm his crotch over his underwear.

His focus is now solely on you and your adamant hand that takes only a few seconds to incite his erection. He extends his fingers to hold your chin as his head dips forward to press a handful of kisses on your lips while he grows harder in the curl of your fist.

“Relax, baby. I got you,” you purr as you peel back his boxers to take a good look at his beautiful cock in all its hard perfection.

Frank stares at you as his eyes grow a shade darker when you stick out your tongue and slowly draw a line from the base of his cock up his shaft. His hardness automatically flexes on your palm as you reach that swollen, pink helmet adorning his erection. The tip of your tongue swirls around the flare of his glans, wetting it with your spit. You gather some more saliva in your mouth and let a dollop drop between your lips to have some more lubrication. It mixes with the sudden drops of precum that come out of his slit.

Staring right back up at him, you take a firm grip at the base and wrap your lips around the tip. You give a little suction, smacking your lips against his skin, making him squirm in his chair. You draw a smile before bowing your head forward to take a mouthful of him. It doesn’t fully fit without you gagging so you mind your eagerness as you move your head back and forth. Your hand tightens at the base, giving him that sweet pressure that earns you a good grunt out of him.

“Fuck,” Frank's eyes flutter shut as you up the pace going up and down his shaft, sucking harder and faster around his now-raging erection, providing those obscene sounds of your vicious blowing. Growing hungry for more, you take him a little further inside until his tip touches the back of your throat.

You hum, moan and eagerly devour him, basking in his arousal that stirs your own. The bitter taste of him makes you wet all the same. You press your thighs together, feeling the dampness of your folds, as one of Frank’s hands lands at the back of your head. He doesn’t push your head down but only grips your hair, letting you take him near the edge at your own rhythm.

Wrapped around your lips, he loses the ability to breathe properly or talk in anything other than curse words. You can tell he's about to pop like a cork on a champagne bottle by the way he throbs on your tongue while his hips start thrusting against your mouth.

Sealing your lips tighter around the head, you grip a little harder on the base and pump with passion until he inevitably explodes, forcing his essence to coat the depths of your mouth. It’s hot and messy, but you swallow every drop of it.

“Goddamn, sweetheart,” he barely mumbles under his breath as you pull your head back and clean your lips.

His head lolls back as you carefully climb onto his lap, watching proudly the mess you’ve made of him.

Cupping his jaw in one palm, you pepper his cheek with kisses as he comes back to his senses under your sweet care. His breathing slowly evens out as your fingers slide over his neck and around his nape to comb his hair.

“How did I do, Professor?” You ask against his ear before lightly sucking his lobe.

Frank clears his throat, planting one hand on your thigh as his opposite arm curls around you.

“Hm.” His eyes tiredly open to look at you. “Think that was a solid B work.”

“What? Are you fucking with me?” You feign offense. “That was clearly an A+ work.”

“Tsk, it was kinda sloppy.”

“It's a blow job. It's supposed to be sloppy.”

You both break into laughter for a moment as Frank regains enough energy to hold your face.

“C'mere, baby.” Reveling in that afterglow, he pulls your head closer so he can capture your lips. His lips bounce gently a few times against yours before swiping a thumb across your bottom lip.

“See? I knew you needed a little break.”

“You always know what's best for me, sweetheart. I might take your offer and hire you as my new D—A.” He snorts, echoing your joke.

“Yeah? What would I get in return?”

“Anything that you want.”

Your forehead touches his as you say under a breath, “I just want you, Frank.”

He smiles softly, licking his lips and smoothing his hand on your denim-clad thigh before gently giving it a squeeze.

“I'm all yours,” he utters intensely before melding his lips with yours in a passionate kiss that fills you with warmth and love.
