Being asked to be Alex Blake’s TA was the opportunity of a lifetime, and when it was presented to me as a first-year graduate student at Georgetown, I took it eagerly and never looked back.

She had personally approached me after I’d finished a semester in her forensic linguistics class as a freshman, and commended me on my dedication to the material and my general work ethic, and then inquired if I’d ever consider filling out an application as her teaching assistant starting the next semester.

I immediately agreed. It was a no-brainer. Blake was a seasoned professional in the career field I wished to enter, not to mention she’d been one of the best professors I’d had whilst taking classes at Georgetown. Knowing I’d be working so closely with her absolutely thrilled me. It provided opportunities I'd have never gotten otherwise.

For example, getting to sit in on the class the famed Spencer Reid would be lecturing on.

She usually kept me quite busy, having me develop assignments and quizzes for her class when she had other responsibilities to attend to. I’d heard horror stories from other TA’s in which their supervisors would delegate ninety-nine percent of the work to their juniors, having them essentially teach the class for minimal recognition or pay. Blake wasn’t like that, and I was thankful. This time around though, she had very different instructions for me.

“You don’t need to prepare any material this time around.” Blake explained to me, and I nodded, listening diligently. “I’d just like you to sit in, and possibly take notes, as you see fit.” She added, and I flashed a polite smile, nodding.

“No problem whatsoever. I’ll sit in the back so as to not bother any students as I do.” I replied, offering her as much convenience as I could within my actions.

Secretly, I did want to catch more than a glimpse from the back of the room. I wanted to experience the esteemed colleague Blake had often spoken of with incredible fondness. I was aware he was slightly older than I was, and a bit socially inept from the way she described him in his stories, but I was also aware the man was a goddamn genius. She’d describe in precision the way Reid would pick up on patterns and leads faster than anyone else on the team, and his immense knowledge in multiple fields beyond criminal profiling. When she’d told me he had three pHDs, I had to hold back a gasp. I hadn’t even started my own doctorate, but the idea only exhausted me- and he had three?! Color me impressed.

Blake, being as brilliant as she did, could sense the hidden enthusiasm in my eyes in meeting this man.

“Honestly, I’d rather you sit in the front. If you’re taking notes for any student unable to attend, it’s more imperative that you know the contents of the lecture, rather than anyone else.” She said, smiling kindly.

“That’s absolutely alright with me.” I say, even quicker than before, nodding, thoughtfully. In reality, the only thing I was thinking about was how close I’d be near the man. I had no idea what he looked like, what he sounded like, but something about him made my stomach flutter.

“I’m sure Dr. Reid would be interested in meeting you, as well. He takes special interest in anyone pursuing our line of work.” Blake added. She didn’t mean for it to happen, but the words made my cheeks light up with a hint of embarrassment.

I don’t know why, but he intimidated the hell out of me. The idea of him taking interest in a conversation with me made my heart beat slightly faster, and I nodded. I tried to convince myself that my nerves came from a purely professional standpoint, but regardless of my intentions, I was absolutely exhilarated by our imminent meeting.

While I knew there'd be initial awkwardness when I'd meet him, given my idolization of the man, I didn’t account for how terrible it’d actually be when I realized how fucking attractive he was. It was almost unfair. I was already tripping over the words I planned on saying in my head, and now he looked like that?

It was cruel.

The soft, doe eyes paired with sharp cheekbones. The slope of his nose, and the mess of brown curls atop his head. Every word out of his mouth was made even prettier by the soft curve and pinkness of his lips, and I found myself wanting to lunge over the table and kiss the hell out of him.

Needless to say, not the right thoughts to have about your professor’s (older) coworker.

While I was initially going to introduce myself to Dr. Reid before his lecture, hopefully establishing myself as a serious individual regarding my studies and eventual career, I shied away, opting for Blake to introduce me instead, nodding politely when he made eye contact with me, exchanging a quiet “hello” and taking my seat in the front.

That was it. And probably how it should be, considering I genuinely couldn’t think straight around him. Students began filtering in, and I took my spot at the front of the room, crossing my legs and beginning to outline his lecture as he began to speak.

He was a brilliant lecturer, and it was honestly criminal he didn’t do this for a living. He gesticulated wildly throughout the whole of it, but every word of his was punctuated with a genuine passion that even some of the best professors on campus lacked. I did my best to diligently keep up with every point he brought up, but with how fast he spoke, it was difficult. Still, an effort was made.

If that wasn’t enough to deal with, I swear the man kept making eye contact with me for the duration of his lecture. At first I believed I was imagining it, that his eyes kept drifting to mine by coincidence, but by the third time, I’d realized that everytime my eyes left his figure to scribble something, I’d look up to see his dark eyes boring into my soul, almost as if he was trying to solve me with a glance. It was intense and made my stomach turn in a way which wasn’t entirely unpleasurable, but I forced myself to remain professional.

Blake did not need to see me absolutely lusting after her coworker, even if he was utterly fit.

Anyway, he was probably only making eye contact considering I was in the front, and probably in an optimal spot for his eyes to focus on whilst addressing the whole of the class. Still, the way his gaze was trained on mine, reaching the deepest parts of my soul didn’t help the growing heat between my legs.

I forced myself to focus on the board, my notes, anything but those godforsaken eyes for the rest of the lecture. Anytime we made eye contact afterwards, I’d quickly look down, like I’d been caught doing something terrible.

Was anyone else seeing this? Was I insane and made delusional by my unexpected attraction to this man? Was he seriously making me wet just by looking at me?

Yes.

Sooner than anyone wanted, the lecture period had completed and Dr. Reid was finishing up. The students were absolutely enamored, especially the girls, as expected. Of course it wouldn’t be just me who’d noticed that in addition to being accomplished in his intelligence, he was also ridiculously easy on the eyes.

Blake stood in the corner, watching her students vacate the space, while some held back to talk to Dr. Reid as he packed his things. He seemed a bit shy at all the attention, but didn’t hesitate in explaining concepts to seemingly eager students, giving them all a soft, shy smile.

God help me, he was adorable. How was I falling for a man I’d never even spoken a word to?

I’d never left the classroom before Blake did, so as she stayed, I did as well, until the three of us were the only ones left in the room. Blake smiled, walking up to Dr. Reid with her hands in her pocket.

“You worked up quite the fanbase, Reid.” Blake said, a little playful.

Reid replied somewhat bashfully. “You have a great bunch of students.” He flashed a small smile at her as they spoke, still packing up his things.

The dynamic between my superior and the man was obviously sweet. They almost looked familial, which made sense. Blake had commented here and there that she managed to spend more time with the BAU with her actual family. I’m sure the latter was the same for Spencer. He probably had a doting girlfriend at home, ready to welcome him in her arms and I mentally kicked myself again for being so attracted to him.

He was nearly ten years older, for god’s sake! Enough! I screamed at myself.

I was brought out quite suddenly from my thoughts when Blake spoke in my direction. “This is (Y/N), my teaching assistant.” Reid came in my direction as I got up and approached him, offering a hand to me. “I’m Dr. Spencer Reid. Blake told me who you were, but we weren’t properly introduced.”

I gave a firm shake to his hand, which I noticed was calloused and smooth at the same time. God, even his hands were pretty. He had long, slender fingers with short-kept nails. They were veiny, and looked strong. I couldn’t help but imagine what they’d feel like inside of me, buried in the heat of my core as I begged him for more.. more..

I forced the thought out of my head, only nodding again at the handsome man. “Nice to meet you, Dr. Reid.” I say, forcing myself to be professional.

Stop thinking about fucking him!

“Spencer works just fine.” He says, imparting a kind smile that nearly made my knees weak. Did he have any idea the embarrassing effect he was having on me?

Out of the corner of my eye, I saw Blake looking at the two of us with a bit of a strange expression on her face. I let go of his hand and took a step back. Oh god. Could she tell? If she could, she said nothing. She gave us both a kind smile, before grabbing her own things.

“(Y/N)?” She called out, starting to walk to the door. “Mind locking up for me tonight?” She said, already throwing her keys to me.

“That’s fine by me.” I say, grabbing her keys mid-air. I was used to this. Blake often wanted to leave a bit quicker than I did, and I was more than happy to assist in any way possible. What I didn’t realize, was that this left me and Spencer in the room alone, something I wanted to avoid, considering how fucking awkward this man was rendering me with so much as a glance at me.

I heard Blake leave, and as she quietly closed the door behind her, I leaned against a desk, keeping my eyes down as Spencer continued to pack his own things. I tried to not let my gaze drift to him, as I waited for him to finish up.

I let my thoughts wander to the lecture, and couldn’t shake the feeling he’d evoked in me when he looked at me like that. This was honestly ridiculous. The man had barely spoken ten words to me, and here I was, absolutely mooning over him. It was a new low for me, but in my defense being a graduate student meant I didn’t have much time to get my .. needs fulfilled.

“That’s why” I convinced myself. I just hadn’t gotten laid in a really long time. Nothing more, nothing less.

“So, you’re a criminology student?” Spencer says, suddenly, breaking me out of my trance.

I looked up, nodding. I responded on pure habit and instinct. ‘Yes, I’m in the process of getting my Masters in Criminology.” I said, nearly robotic.

“That must be interesting.” Spencer replied, flashing me a sweet smile that caused an entirely new slew of butterflies to erupt in my stomach. “I never studied criminology specifically, but the classes I took interested me.”

“Blake told me you had three pHDs.” I acknowledged, trying to return his smile, but in all honesty, I probably looked like an idiot. I was nervous as hell, and hoped he couldn’t tell. It wasn’t my fault. He was awe-causing. A sight to behold, if you will, in intelligence and appearance.

He laughed good naturedly, “Yeah. Three.” He must’ve noticed the stars in my eyes, because he continues. “As well as a Bachelor of Arts in Psychology and Sociology. And I’m working on another in Philosophy.” He finishes with a smug, boyish type of smile.

What was previously stars in my eyes, was now full blown shock all over my face. “Wow, Spencer.” I said, a little dumb-struck. “That’s.. a lot.” I add, a little stupidly, giving him a little laugh.

He sweetly scratched his neck, revealing his self-consciousness. “Yeah? You think?” He says, a small smirk in his voice, and I laughed again. “You think I should stop after Philosophy?”

“Totally. Save some knowledge for us.” I teased. It was comfortable. He was surprisingly easy to get used to. He was affable, despite how daunting his knowledge was.

“Hey, you try graduating before you’re a teenager.” He defends himself, playfully. “Not much to do, really.”

I laugh. “I don’t know.” I say, throwing my hands up a little. “Play ball? Run around?” I joke, and he makes a face at that, scrunching up his nose.

“Not my thing.” He replies, smoothly, and I laugh.

“Alright, fine. Keep your degrees doctor man.” And he laughs at my joke. Like, a real laugh. I didn’t even find my own rhetoric particularly humorous, but knowing that I’d gotten him to react like that made my cheeks glow.

He finished packing the last of his things and slung his satchel bag over himself, starting to walk over to the door. I made sure to gather all my things, and walked to the door with him. He held it open for me, and I nodded my head in thanks, and he let it shut behind us. I turned around to lock it, using Blake’s keys and placing them in my bag securely, before looking at him.

“Well, Spencer. It was nice meeting you, thank you for the lecture it was-” I start, but he interrupts me.

“Can I walk you to your car?” He interjected, looking a little shy as he did. I smiled a little confusedly, wondering why he’d want to do so, but I gave him my answer, nonetheless.

“I don’t have a car. I usually take the bus back to my apartment.” I explained, smiling softly.

“The bus?” He says, quirking his mouth to the side. “Isn’t it a bit late for that?” He replies, a hint of concern in his voice.

I gave a little sigh, “I mean, it’s fine.” I say, trying to laugh a little. “I’ve done it before.” I add, attempting to ease the worry out of his voice. “It’s not that late.” I say, but he simply shakes his head.

“No way.” He says, still adamant on this. “I.. I can drive you home, if you’d like?” He says, his words going slightly on the higher pitch as he rolled out his proposal, and I gave a small grin at that.

“Really? If it’s a hassle I can seriously just take the bus. I wouldn’t want you to keep anyone waiting at home or-”

He interjects again. “No hassle. I promise. I want to.” He pauses, before adding, “No one at home. You’re probably going to be the last person I see today.” He seems to blush at his final admission, and my eyes widen in interest. No girlfriend? Score.

“Alright, Spencer.” I say, smiling again. “Lead the way.”

He led me to his car, an old-fashioned Volvo and I couldn’t help myself from gawking at it.

“God, you have a cool car too? Is there anything about you that isn’t interesting?” I say, aware I was probably stroking his ego a bit, but honestly I wanted to. The man was just so damn intriguing, and every new bit of information I learned about him only made me want to unravel the whole of him. To truly know him, in and out.

He laughed, using his keys to manually unlock the door. “Oh, trust me. I’m plenty boring. The car is probably my only saving grace.” He joked, and I laughed again as I got into the car.

“Oh, I highly doubt that, but if you say so.” I say, sweetly, and adding a light tone of flirtatiousness in my tone. He seems to blush at this again, and I begin to think about the events of day. The stares in class, the perpetual rosy tint on his cheeks that had been there since we began our conversation, the way he joked and laughed at my (admittedly, unfunny) jokes.

Oh god. Did he like me?

Only one way to find out.

As Spencer got in the car and began driving onto the main road, I looked at him, trying to put on my best, innocent smile. “So, you said you’re not going home to anyone?” I say, a softness to my tone, but an undeniable hunger in it as well.

“Uh.” He responds, that damned blush coming on, strong. “Yes.” He replies, nodding as he keeps his eyes on the road.

“So, you don’t have a girlfriend?” I ask, a bit forwardly.

Now he’s really blushing, stuttering a bit. “Oh, no. No girlfriend. Not much time, given the BAU and our schedule.” He said, almost clinically, and I nodded.

“I mean, Blake has a husband.” I point out, a little smugly.

“I guess.” He says, sighing a bit. “But, you know.” He says. He vaguely gestures to himself, and I look at him a little confused, tilting my head at him.

“Spencer, I have no idea what you’re trying to say.” I say, with a little giggle. “But trust me, you’re absolutely gorgeous.” I continue, before I can stop myself.

He looks at me, giving me a soft smirk, and a raise of his eyebrows. He didn’t look uncomfortable, and honestly looked just as thrilled as I did, and I knew that this night had a good chance of going the way I wanted it too.

“Ah, you’re sweet.” Spencer replies, “But no. I just mean, I’m.. me. You know?” He says, trying to explain his (non-existent) shortcomings, but I just shake my head.

“You don’t give yourself much credit, you know?” I attempt to say with that amorous tone from before, but it was more overcome with genuine respect and admiration. “You’re smart, funny and nice to be around, I mean.” I pause. “Did you not see the absolute crowd of girls around you after the lecture? Trust me, Spencer. I bet you’re more than easy to be with, even easier to like.” The words rush out of me, and I watch him tentatively for his reaction to my words.

Instead of the sweet side smile he’d been offering me all night, he finally looked at me. The car had come to a stop at a red light, and his face was dangerously sexy as it was illuminated by the colored glow around us.

“And what do you think?” Spencer says, in a low tone, making direct eye contact with me.

I feel my stomach turn at the sudden directness in his words, his gaze nearly devouring me whole. I felt my mouth go dry and I swallow, trying to keep my tone steady.

“What do you mean?” I ask, my voice having a slight shake to it.

“I mean, what do you think about me? Do you.. like me?” He says, licking his lips slightly, and the action causes the previous heat between my legs to come by in full force.

“Oh, I mean.” I say, my previous confidence dissipating in an instant. “Well, yes, Dr. Reid. Everyone liked you today.” I say, trying to give more of a conservative answer now.

The man had a way of making me feel totally comfortable around him, and then flipping the switches, rendering me dumb and stuttering. Like I was now.

“Oh, so I’m Doctor Reid now.” He says, clicking his tongue and saying the words with an air of lighthearted teasing, but I only bit my lip, hurriedly trying to explain myself.

“I mean, it's your title.” I say, quickly, trying to justify myself. “I mean, you said it yourself- three pHDs. It’d be pretty shitty to just discard the years taken to achieve that. Um. Well. You’re a genius so probably not as long, but still! Calling you doctor is a sign of respect for your accomplishments and-”

“You're cute.” He interrupts, and I look back at him to see his eyes back on the road, a cocky smile plastered on his face.

The light around us turned green, and he started the car. I picked at my nails slightly, trying not to display any more signs of nervousness around him. I wanted to do something with him, at least, and that couldn't happen if I was a bumbling mess.

We drove in relative silence for the next few minutes, as I tried to gather my thoughts and possibly continue what we’d been building up to these past few hours, but a quick glance at the windows and the road we were on caused me to furrow my brows.

“Oh, this isn’t the way to my apartment.” I remark absentmindedly, looking at the window beside me, then in front. “I live near the train station, off east?” I offer, expecting him to fully make a turn back towards the direction I’d prompted him towards, but he didn’t even flinch, continuing on the more secluded road we’d entered.

“I know.” He said, glancing at me once more, actually applying more pressure to the gas pedal, causing us to go faster down the terrain.

Okay, fuck. He was an FBI agent, so I didn’t have to worry about him murdering me, right? Wait, no, that’s stupid. He could probably get away with it. No! He’s Blake’s friend. Her coworker. For the goddamn FBI. He wouldn’t murder me. What the fuck was going on?

I watched as Spencer pulled off to the side of the road, darkness surrounding us entirely. There weren't any other cars around, and it was silent in the car before I bit my lip, and started to speak.

“Did I.. offend you?” I ask, cautiously. No reply. I try again. “Why did we stop?” I add, trying to test the waters with him to see what he was thinking at that moment.

“I thought I could wait before we got to your place, but I need to know now.” He replied, a sudden urgency in his voice. He turned towards me, watching me with a dark, intense gaze, similar to the one he'd given me in class that day. “Do you want me? Am I reading this wrong with you? Because if I am, we can completely forget it and I can drop you home but (Y/N)..” He paused. He made direct eye contact with me and once again I found myself wanting to swim in those dark eyes of his. “I want you.” He said, his voice low and raspy.

I didn't give it much thought as I gave into my urges and surged towards his lips the best I could in the car. He responded immediately, bringing me closer with his hands and placing them on either side of my face, moving his lips against mine in a perfected rhythm. I used my fingers to quickly undo my belt, before climbing over the console to sit in his lap, getting closer without our lips disconnected once. He understood my actions and intentions immediately, pulling the seat back so I could rest more comfortably in his lap as we continued to kiss.

I knotted my hands in his hair, giving an experimental tug which elicited a low moan from his mouth. I grinned against his lips and his hands moved from my face to his hips, bringing my clothed core to rest right against his growing bulge, which I immediately moved against. He let out a sharp breath as I did and broke the kiss.

“Oh god. I’m sorry.” He said, breathlessly, hands on my hips. “I don’t know what came over me and-”

He looked almost frantic, and incredibly guilty, so I quickly leaned in for a peck, stopping him mid sentence. I brought my hands to his shoulders to rub them soothingly, and he seemed to relax in my touch.

“Spencer, calm down.” I say, nearly purring. “I want this.” I continue, rubbing patterns into his arms now. “Please.”

“You’re Blake’s student.” He murmurs, using one of his hands to run through already messy brown curls. “What am I doing?” He says, almost to himself, looking ready to stop our tryst.

I realize he was attempting to backtrack from this, and before he could continue his train of thought, I quickly leaned in from my position on his lap to start kissing his neck, trailing wet hot kisses down the column before whispering. “I’m not her student.”

He pulls away to look at me, biting his lip. “What?”

“I was her student last semester. I’m her teaching assistant now.” I smirk a little, licking my lips. “Technically not a student of hers.”

He seemed to take in my words for a moment, and then something in him shifted, and he lunged at me again, kissing me with even more ferocity. He absolutely devoured me, his hands everywhere at this point. Caressing my sides, in my hair, on the small of my back. He brought me closer to him in any way he could, pressing our bodies against each other in a frenzied manner that caused the wetness between my legs to increase tenfold.

“Wanted you.. as soon as I saw you.” He murmurs against my lips as we caught our breath in between kisses. “Knew it was wrong but..”

I nodded. I understood. I was the same.

“Fuck.” I moaned, as I felt the bulge resting below me get even harder. “Spencer, please. Don’t make me wait.”

“Impatient.” He remarked, smirking, now beginning his own line of kisses down my neck, making me moan in pleasure.

“Please.” I breathed out, my words being reduced to a squeak as he bit my neck gently, and my eyes fluttered shut. I was melting right in his damn hands, just like he wanted.

His hands started to work at the buttons on my jeans, and I sighed in relief, lifting up my hips to allow them to be tugged off, leaving me in my underwear. His slender fingers traced the seam, leaving me shuddering with pleasure for the man in front of me. I tried once more, breathlessly murmuring at him.

“Please. Please.”

“Use your words, baby.” He whispered, a devilish smirk on his face. I was too far-gone to care about what I looked like. I needed him so badly.

“I need you to fuck me, now.” I say, clearer. “I need it, Spencer.”

Something about me using his name, nearly moaning for the man when he’d barely touched me stirred something in him, and he started to undo his own slacks, freeing his cock from the confines of his briefs. I watched in fascination as it sprung out, and took in a sharp breath of air. I licked my lips before making eye contact with him, begging for us to get on with it at this point. He nodded, understanding my desperation and I smiled dumbly, beginning to lift my hips. He guided his cock to my heat and placed his free hand on the small of my back, slowly guiding me down his member.

I moaned softly as I felt him enter me, providing me with the most delicious stretch. I threw my head back in pleasure as he brought both his hands to my hips urging me down.

“That’s it. God, fuck. You feel so good.” He moaned, which only made me want to take more of him. I lowered myself down a bit faster, and he released a heavy groan as his hips met mine. I whimpered slightly, his length filling me up perfectly. A thin sheen of sweat had gathered on my brow and I leaned my forehead, adjusting to his size.

“You good?” He breathed out, using his hand to brush a piece of hair that had stuck itself on my brow, and I nodded.

“Yeah, just.” I took a deep breath, before licking my lips, looking up before nodding.

I slowly lifted myself off, letting the head of his arousal nestle in me before I slammed back down, eliciting moans from both of us. He began to match my movements in tandem, thrusting up into me wildly. I held onto his shoulders, burying myself in his neck as we went faster. I could feel his tip hitting my cervix every time, causing me to cry out with pleasure every single time.

I felt my orgasm rapidly approach, and Spencer seemed to sense this as well, considering the involuntary clenches I was giving around his cock. He let his hand slip down to where our bodies met and rubbed tight, fast circles around my clit, encouraging my release.

“Come on, pretty girl. Come all over my cock. You can do it.” He breathed out, watching my every move with a hunger I'd never experienced before.

It took a few more thrusts from him, combined with the insistent fingers at my bundle of nerves before my thighs began shaking, and I let out a chorus of moans, most of them sounding like strangled versions of his name as I coated his cock in my wetness, spurring him on to go faster inside me, bucking into me like a man possessed.

He continued to jut into me wildly, until I felt him finish inside me, coating my walls with his release. He breathed shakily, holding me close to him as I slumped over his shoulder, my chest heaving up and down as I came down from the intensity of the previous moment.

He affectionately removed me from his shoulder, pressing a soft kiss to my lips, the tenderness and gentleness in his actions contrary to what we had just done. I pulled back with a dazed smile, taking in how pretty he looked.

“If it’s alright, I’d love to take you out for coffee sometime.” He said, still a bit breathless, and a shy smile appeared on his face.

I giggled. He was literally still inside me, and was asking me out on a date with a boyish nervousness that made him even harder to resist.

“For you Dr Reid? Anything.”
