Characters/Pairing: Derek Morgan/Spencer Reid
Summary: So Spencer awkwardly stumbled through this evening in hopes that things would just take their natural course. That was how these things worked after all, didn’t they? One thing led to another and by the end of it you were panting and sweating and basking in the afterglow.
Author's Note: This is the first fanfic I've written in at least a year and my first CM fanfic ever, so I'm definitely open to constructive criticism! This is the beginning of what I want to be a PWP series.
There is dim, orange light blanketing the room and mellow music drifting from the speakers, but the only thing Spencer knows in that moment is Derek Morgan. His lover’s mouth is pressed against his, all soft, imploring lips and warm, talented tongue. Reid feels overwhelmed, every muscle in his body yielding to the man slowly working his way atop him. His lithe body slides downward, sinking into the cushions of the couch as Derek kisses him. Derek’s body is warm and hard above him, volatile and safe all at once. He can feel every inch of the other man against him, the thought of which makes him blush. Because if Spencer can feel everything that is Derek, Derek can certainly feel everything that is Spencer. This would also include the erection growing between his legs.
A nimble yet curious hand reaches upward, coming to rest on Derek’s arm. He feels muscles bunching and relaxing beneath his palm. The practiced cadence of his movements reminds Spencer of how grossly inexperienced he is at all of this. There is something in Derek’s movements, an ease and grace that Spencer has not known in his entire life. He pulls back slightly from the other, his breath coming in short little pants.
“I’m sorry,” are the first words Derek says. “I didn’t mean for things to get out of hand like that.”
Something between a cough and a chuckle comes from Spencer’s throat. “I think it’s fairly obvious I didn’t mind.” He pushes his hips upward, brushing the bulge in his pants against Derek’s thigh.
Derek’s eyebrows lift upward, a smile lighting up his face. “Well, well. Seems like you‘re full of surprises tonight, Pretty Boy.”
Spencer had the decency to blush.
In the few months the two of them had been seeing each other, neither man had made any moves towards taking their relationship past heated make-out sessions. And while it was mutually pleasurable for the both of them, Spencer could tell that there was something lingering inside of Derek, something that he wasn’t letting the other man fulfill. He could feel it when his hands continued to wander long after his lips had stopped. He could hear it in his voice, his moans a pleading cry for more whenever Spencer dared to pull away. But most of all he could see it. He could see how his body tensed up, how he started to lose control, how he unwittingly guided their bodies into a horizontal position. It was clear that Derek wanted more, and while Spencer certainly wasn’t opposed to the idea he wasn’t exactly experienced when it came to relations of that sort.
So Spencer awkwardly stumbled through this evening in hopes that things would just take their natural course. That was how these things worked after all, didn’t they? One thing led to another and by the end of it you were panting and sweating and basking in the afterglow. Any previous experience Spencer had in this area was strictly experimental. A few curious couplings with girls who were only vaguely interested in him aided his understanding of the basic mechanics. But in those cases, putting theory into practice had not been as fulfilling as he’d hoped.
He was fairly certain this would not be the case when it came to him and Derek.
Spencer goes to move from the couch, Derek frowning slightly, but Spencer smiles reassuringly and rests his hand on top of the other man’s.
“I want you to take me to bed.”
It’s only a split second before Derek is practically jumping off the couch, pulling Spencer up with him. Spencer would laugh at how eager his lover is if he didn’t feel so nervous. Derek leads, taking them down an unlit hallway towards the bedroom. The music and warm, orange light seem miles away as they venture further into the house. When they finally reach the bedroom door, the music is only a hum in the distance.
Spencer hears more than he sees the door open, the creaking noise setting his heart into a frantic pace. He had hoped that it would be easier than this, that he wouldn’t have to think about it as much, that it would just flow through him. But the walk has him reconsidering, has him doubting that he can do this. He wasn’t a sexual person - he was awkward and clumsy and what if in all this letting himself go he did something that Derek didn’t like? What if he embarrassed himself or, worst of all, somehow pushed Derek away? He had been happy with things the way they were. The way things were was more than he could ever hope for. It had been a ridiculous idea for him to try to-
“Spencer.”
The sound of his name forces Spencer to look into the eyes of his lover. Concern is written all over his face. “Are you sure this is what you want?”
Taking a deep breath, Spencer says, “I do… I mean it has nothing to do with me not wanting you. It’s just that I don’t… I feel like I‘m going to disappoint you or something.”
Derek squints his eyes as if he hasn’t understood. “Disappoint me?”
“Yes. Disappoint you, disgust you, turn you off. I know you want this, and I want it too but I’m not… I’m not like you. I’ve read books.”
The corners of Derek’s lips are lifting upward. “Books, huh?”
Spencer nods frantically, panic forcing words out of his mouth and sending his hands flying in every direction. “Yes. I have so many books about sex lying around my house right now that I could probably open my own erotic book shop if I wanted to. But that’s not the point. The real point is that reading about sex and actually having sex are two completely different things. And that’s what I‘m afraid of. I’ve not had a lot of practice, definitely not as much as you. And, sure, I can read about the best way to give a blow job or what kind of positions produce the most intense orgasm but it doesn’t mean I’ll be any good at any of it!”
Spencer’s tirade didn’t have the effect he expected it would. Instead of looking unsure, a wide smile spreads across Derek’s face. He closes the distance between the two of them, pushing Spencer against the wall before placing a small bite at the base of his neck.
“You wanna give me a blow job?” Derek’s voice is heavy and hot against his skin, causing a tiny whimper to escape from Spencer’s lips. “All you had to do was ask.”
“No, Derek, you don’t understand…”
“I don’t?” Derek pulls back, his piercing gaze set right on Spencer‘s face. His hand slides downward, only stopping once he has Spencer‘s erection cupped in the palm of his hand. “I think I understand this pretty well.”
And Spencer’s forgotten all about words then. At the moment, Derek’s hand is the epicenter of his world. He pushes into him as Derek slowly rubs his palm against the fabric. Spencer’s head falls against the wall, short, breathy pants passing his lips. All the knowledge he possesses disappears, saving itself in some remote corner of his brain as he focuses on the magic Derek works on him.
“Der…ek…” He can barely get the name out, his hips thrusting into him desperately. He hopes that his lover can understand what it is he wants because he’s not sure he can form enough words to express himself at the moment.
Thankfully Derek takes the hint, removing his hand and leading them over to the bed. Derek is on top of him before he even fully comprehends it. He can feel hands running through his hair, down his cheeks and tickling at his neck. But as nice as it all is, Spencer can’t ignore how every limb in his body is begging for more. He moans quietly, arching into Derek’s touch as a quiet “Please…” leaves his lips.
He hears Derek’s smile more than sees it, the chuckle he lets out rumbling softly against his ear. He feels Derek’s hand move lower, reaching the collar of his shirt. A shudder runs through him as each button pops free, revealing more and more of his skin. He feels ashamed, his skin suddenly more pale than he remembers it being. The moonlight coming in the window makes his white skin glow, and not in a way that Spencer thinks is particularly attractive. When his shirt is gone, he makes to cover himself, but Derek stops him. His strong grip forces Spencer’s hand back down.
“Don’t hide,” he says softly, leaning down to press a lingering kiss to his lips. “I love seeing you like this.”
Spencer’s face heats up. He doesn’t really understand what it is Derek sees, but he’s glad he seems to enjoy it. But this isn’t all about Derek. It has a lot to do with Derek, but it’s not just about him. His face getting even hotter, Spencer says, “It’s not fair that I’m the only one getting undressed.”
Derek smirks, running his fingers over the back of Spencer’s hand. “Well, if you don’t like it, Pretty Boy, maybe you should do something about it.” He lifts Spencer’s hand, placing it at the hem of his shirt.
Spencer gets the hint, but that doesn’t mean he particularly likes it. He feels anxious exposing his lover like this, though it’s clear that’s what he wants. Biting his lower lip, Spencer begins to lift up Derek’s shirt, gasping softly as plains of brown skin are revealed to him.
Seeing Derek shirtless isn’t something completely new to Spencer, but he can’t help the fluttering of his heart as he pulls the shirt further up. He vaguely muses to himself that Garcia’s assessment of him as a “sculpted god of chocolate thunder” might actually not be an exaggeration. Derek lifts up his arms and the shirt goes up over his head, then down somewhere near the side of the bed. Spencer is entranced. Both hands come out to rest on the expanse of Derek’s chest, reveling at the smooth skin and the hard muscles. He has felt Derek’s body before, but not like this. His hands travel downward, tracing patterns over his abs before stopping just above his jeans.
Spencer doesn’t notice the effect he has on Derek. He’s rather enthralled himself, body seeking out Spencer’s faint touch unconsciously. While he’s happy to let his lover touch him, these teasing caresses are making it hard for him to keep control of himself.
Spencer looks up at him suddenly, his eyes lidded and speaking of a lust they’d not previously explored. “Derek,” he whispers, his fingers never stopping their exploration of his body. “Can I taste you?”
Derek groans, the tone of his lover’s voice making a shiver run down his spine. “Do you honestly think you need to ask permission?”
Spencer’s only response is a shrug, his attention set on the flawless mocha skin before him. He leans forward, hesitating for only a second, before pressing his lips against Derek’s neck. Immediately, his lover’s hands are around him, pulling them closer together. Spencer doesn’t protest, sucking devoutly at Derek’s neck before trailing his tongue down to his chest. His hands tickle at Derek’s sides as his plush lips catch onto a nipple. A loud groan rumbles through Derek’s chest, the feeling of Spencer’s tongue and teeth laving against the nub sending the most intense pleasure coursing through his body. “Spencer,” he moans, arching his back into his lover’s fervent touch. “Fuck, that feels good…”
Spencer, urged on by Derek’s words, moves his mouth lower. He lets his tongue trace over the well-defined muscles of his stomach, reveling at the perfection that is his lover’s body. He nibbles his way downward, letting out quiet little moans every so often, until his chin brushes against the crotch of Derek’s jeans.
There is a brief moment where Spencer isn’t sure how to proceed. Being so close to his erection, he couldn’t help but feel somewhat intimidated. Even unexposed, it seemed much larger than he anticipated. Derek moves around beneath him, probably about to reassure him that he didn’t have to do anything he didn’t want to. But the more he thinks about it, the more appealing Spencer finds it. To take his lover into his mouth, to pleasure that most sensitive flesh with his lips and tongue, to have that kind of power over him… He undoes Derek’s jeans, pushing them down past his hips until he is met with his lover’s hard cock.
He tentatively runs a finger over the head of his cock, eyes flicking upward when he hears Derek draw in a breath. His lover’s head is tilted backward, the quickened pace of his breath causing his chest to rise up and down at an increased pace. Spencer can hear him moan, feels him rock against that finger, but even though his lover clearly wants more, Spencer isn’t ready to give it all to him yet.
He grips Derek in his hand, marveling at how different they are. He notes how his cock is considerably thicker, feels heavier and hotter than his own as he begins to stroke. The weight of him is pleasant and somewhat intimidating as Spencer considers just where his lover’s cock is going to be. He’s no longer than Spencer really, perhaps only by an inch or two, but the girth of him is what impresses Spencer most. He likes the heaviness of Derek. It fits well with the rest of him. He is substantial, impressive. Spencer can almost feel him pressing the tip of his cock against his entrance, pushing him apart, possessing him.
As soon as the thought enters his mind, Spencer leans further down, his lips only inches from Derek’s cock. He can feel his lover’s body quivering in anticipation. He licks his lips, embracing the heat that emanates from Derek’s skin. It infects him, makes him roll his hips against the bed.
“You’ll tell me if I do anything wrong, right?” Spencer pants.
Derek can’t even manage words at this moment. He just grunts, giving a few pathetic nods of his head.
And then Spencer is on him. He starts first by flicking out his tongue, tasting the salty precum that has begun to gather at the tip. The taste isn’t wonderful, but the reaction he receives from his lover most certainly is. Derek’s hand flies from out of nowhere, fingers desperately clinging to clipped, brown locks. His back is arched, his hips reacting instinctively to Spencer’s inquisitive touch.
Spencer doesn’t notice it, but he starts to lose himself much like he imagined he would. He focuses on wrapping his full lips around Derek’s cock and minding his teeth as he takes him in, inch by torturous inch. The hand at the back of Spencer’s head grips tighter, pulling at his scalp until the movement stops. Spencer’s tongue then flicks out, caressing the underside of him as he pulls back.
And if Derek wasn’t moaning by then, he definitely is now. The sound reaches Spencer’s ears and has him beaming proudly. He doesn’t have much time to bask in his accomplishment of making Derek Morgan moan, as his lover gasps out the word, “More.” And Spencer is more than happy to oblige.
When Spencer has him in his mouth again, he sucks, his cheeks hollowing around Derek’s hardness. And it’s like he’s pulling all sorts of reactions from him. He can hear things that sound like moans and gasps and very near sobs. He continues to slide his mouth along him, cautiously moving a hand between them to cup his balls. And that has Derek bucking again, his voice so loud it seems to echo off the walls. Spencer speeds up his pace, smiling to himself when he feels Derek’s balls tighten in his hands. He wants to finish him off like this. He wants to know that he can make his lover come with nothing more than a few flicks of his tongue.
Unfortunately, his lover has other ideas.
When Spencer pulls back for a breath, he suddenly finds himself on his back, staring up at his Derek’s face.
“Mm, and just what did you think you were doing, Spencer?” His lover’s voice is lower than usual as he leans down to nip at his neck.
“I didn’t hear you complaining,” Spencer says, his voice hitching as Derek’s teeth graze his collarbone.
“You told me you wanted me to take you to bed,” Derek whispered as his mouth continues its way downward.
“And we made it here safely. I thank you for that.” A groan passes Spencer’s lips when he feels Derek’s warm mouth around his nipple. “But…you also said that…if I wanted to give you a blowjob all I had to do was ask…”
“Ah.” Derek admonished him with a chaste bite to his nipple. “But you never asked.”
“Not in so many words, maybe. But I do recall asking to taste you. And at last glance, your dick is most definitely apart of you.”
Derek smirked. “Hmmm. I guess you’re right then.”
“Of course I am, Derek. I have an eidetic memory after all.”
“Mhm. But that’s not all you have.” Derek kisses his way down Spencer’s flat stomach, only stopping to leave little red bite marks at his hipbone.
“It’s not?” Spencer said mockingly. “Well, what else do I have then?”
Spencer watches his lover reach over him and begin to rifle through the top drawer of his nightstand. He blushes, knowing exactly what Derek is searching for. Anxiety starts to set in again, his stomach twisting uncomfortably. He wants this with Derek, he knows in his heart that he does, but he can’t stop the feelings of self-doubt that creep their way back into the forefront of his mind.
“Spencer.”
Brown eyes filled with apprehension gaze up at Derek. “You okay?”
Spencer didn’t want to worry. He just wanted to enjoy this, enjoy sharing this with Derek. But he was nervous again. So instead of answering the obvious question, he asks, “What else do I have, Derek?”
Derek frowns slightly, but after a moment he seems to get the hint. He pushes Spencer’s pants down and off his body before coating his fingers with lube. Quietly, he jests, “Well, where do I start?” He smiles and leans himself over Spencer. Carefully placing a hand at his hip, he slides in the first finger. “Well, for starters, you’ve got these eyes.”
Spencer gasps at the pain. The burning that permeates his backside is more than he had anticipated. He looks at Derek worriedly, afraid that he won’t be able to take it. But his lover reassures him, whispering softly to him, “Just relax.”
As Spencer tries to calm himself, Derek continues. “You’ve got the prettiest eyes I’ve ever seen. They’re inquisitive and curious, always looking for answers. And they kind of look like gold in the right light.”
Spencer wheezes out something like a chuckle, his body relaxing enough to let Derek push his finger the rest of the way in. “I…never took you to be a romantic, Derek,” he mumbles.
Derek simply hums in response. “And your lips...” He pulls back his finger and thrusts in again. “I think you lick your lips all the time on purpose. Like you know that I love it secretly. And after seeing what your mouth can do tonight, I think it’s gonna be even harder for me to take my eyes off them.”
Derek moves his finger faster as he feels Spencer’s body start to relax. He curls his finger carefully, searching for his sweet spot. And when Spencer’s eyes flash open and his body arches off the bed and he cries out Derek’s name, he knows he’s found it.
“Oh my God, Derek,” he pants. His hand comes to rest on Derek’s wrist, silently urging him on. “More. Fuck, do that again.”
Derek smiles and adds a second finger, careful to avoid too much stimulation to his prostate should the evening come to an end far sooner than he hoped. “I love your body too, Spencer,” he whispers as he licks up the long column of his neck. “It’s just as amazing as the rest of you. You’re so long and lean, but I can feel all that strength underneath your skin.” Derek scissored his fingers inside the other. “You’re strong, Spencer. Stronger than I think you even realize.”
But Spencer’s too far gone to really pay attention to Derek’s words anymore. He’s riding Derek’s fingers, panting and tossing his head from side to side. His fingers dig into the bed sheets as Derek adds a third finger. This time the sting isn’t as bad, but it’s still there. The hiss Spencer lets out fades into a desperate whine. His hips are rolling frantically against Derek’s fingers, little yelps of bliss coming from him whenever he just so happens to find that spot.
“Derek,” he manages to groan. He groans even more when he feels Derek’s movements stop. “No, don’t. Don’t stop. Just…fuck me.”
Derek’s fingers accidentally brush against that spot, making Spencer let out a yell so loud Derek is thankful the walls of his home are thick.
Spencer stares down his thin frame, his eyes narrow and dark, and growls, “Fuck me. Now.”
His boyfriend’s sudden boldness takes Derek aback slightly. But he likes this Spencer, the one that’s willing to demand satisfaction. Derek reaches between Spencer’s spread legs, unwrapping the condom which he had grabbed along with the lube. He gently pulls his fingers from Spencer’s entrance and smirks at how he clenches around them. There is a definite desire to please his lover, but Derek can’t help thinking about how good it’s going to feel. He had been wanting this long before they even entered a relationship. Little goose bumps of excitement broke out over his flesh as he slid the condom on, slicking himself up with perhaps a little more lube than necessary.
Spencer sat up, interested to watch his lover prepare himself. He was a bit disappointed, seeing Derek’s cock covered by latex. Certainly, he would never expect Derek to be unsafe, but Spencer didn’t much like the idea of a barrier separating the two of them. He wanted to feel all of him, especially that particular part of him.
A soft kiss from Derek captured his thoughts. Their lips and tongues moved sweetly against each other. Derek’s hand came to rest on Spencer’s jaw as he pulled back, his thumb softly caressing his cheek. “Just try to relax, okay?”
Spencer sucks in a breath as Derek starts to push inside of him. It does not take long for Spencer to realize that this is considerably harder to deal with than his fingers. He grabs onto his Derek’s arm, biting his lower lip to keep himself from asking him to stop. He can feel Derek’s thumb rubbing at his hip but it does little to soothe him.
He sighs when the intrusion ceases. Spencer’s eyes blink open to find Derek staring down at him worriedly. “Do you want me to stop?”
And Spencer frowns then because the first answer that comes to his mind is yes. But that isn’t the right answer, not now, not when he sees Derek struggling not to bury himself to the hilt right then and there. He shakes his head, laying himself back against the mattress. “Just go slow…”
Derek nods and continues, trying to keep the gasps of pleasure at bay till Spencer seems to at least be enjoying this a tiny bit. His softening cock not gone unnoticed, Derek grasps him in his hand, twisting his wrist as he strokes him slowly. He knows it won’t be enough to make him completely forget the pain, but he hopes it’s enough to distract him, even a little bit.
As Derek’s hand works over him slowly, Spencer finally feels his body start to relax. His muscles unclench themselves and a familiar tingling sensation covers him. He sighs softly as Derek’s thumb swipes over the head of his cock.
And then Derek sits fully inside of him. He relishes how tight Spencer is, how perfectly his body envelops him. His hand has almost completely stopped at this point as he revels in heat of the moment
When Derek’s hand stops moving, Spencer looks up through lidded eyes. He sees the look of bliss on his boyfriend’s face - his lips parted and eyes closed as shallow breaths cause his chest to rise and fall seductively. He looks lovely, so much so that Spencer is willing to let him stay like that for a least a few moments. But as he grows more and more used to the feeling of having Derek inside him, the more impatient he becomes.
“Derek…”
His eyes open slowly, glazed over and dark. He pulls Spencer into a biting kiss, his hips rolling shallowly as he sucks at Spencer’s lower lip. The way he rocks against him makes little sparks of pleasure go off behind Spencer’s eyes. He gasps, grinding himself down on Derek’s cock until he finds that spot again and suddenly he’s shouting the name of every deity he’s ever even remotely heard of.
Derek breaks their kiss and lets Spencer fall back onto the bed. Spencer arches his body eagerly as Derek pulls out slowly, teasingly, and slides back into him at a wondrously swift pace. His pain mostly forgotten, Spencer focuses on how amazing Derek’s cock feels inside of him. He likes how whenever he moves his hips his body seems to lose control of itself, his toes curling and voice rising and teeth clenching of their own accord. He likes how when Derek pushes himself inside, it feels like he’s going deeper each time. He likes how it feels to be splayed apart, his boyfriend’s hips picking up speed with every moment. But what he likes the most - what he loves - is that mounting pressure in his stomach. He feels it building up, the excitement flooding his limbs to the point where he can scarcely keep himself still. It burns at his insides, making him writhe and pant and beg for more. He wraps his legs around Derek’s waist, groaning out none too quietly, “Harder.”
Derek is more than happy to acquiesce to this request. His fingernails dig into Spencer’s hips so deep that there will surely be marks in the morning. But he can’t be bothered to care, not when his lover is begging like he is, his entire body flushed a sinful shade of pink. He lifts up Spencer’s hips, changing their position, before driving into him again. And that little move earns him several desperate yelps of pleasure from his lover. Derek doesn’t relent, moving his hips faster as he feels his orgasm drawing near.
Spencer is almost completely lost in that moment. His eyes shut tightly, all he can do is feel, and what he feels is Derek hitting his sweet spot dead-on. And that feeling is like the sweetest pain Spencer has ever known. He craves release, begs for it, but God he never wants it to end. The pleasure that racks his body knows no bounds and before he can stop it, it becomes too much. He cries out as he’s drawn over the edge, losing all sense of himself as sweet oblivion consumes him.
Derek watches Spencer as he cums and in that moment he can’t really think of anything more beautiful. His back jumps off the bed, curved into an almost painful looking arch, and his fingers clench so hard his knuckles turn white. His eyes are shut tightly but his mouth hangs open, letting all the tension and pleasure release itself into one long, keening, satisfied moan. His muscles all constrict, especially the ones that still surround Derek‘s cock. He manages a few more pathetic thrusts but he knows he’s gone when he hears Spencer whisper his name. He buries himself inside of him, letting his lover’s body pull his orgasm from him.
When Spencer comes down, he realizes that Derek is not on top of him but at his side. Derek looks about as ragged as he feels, his chest still heaving rapidly and sweat still beading at his brow. Spencer can’t recall a time when Derek looked better. He rolls over to him, kissing him, hoping that his lips adequately express the passion and pleasure that Derek has shown him.
Derek happily relaxes into the kiss, his hand coming to rest on the small of Spencer’s back. And it’s not particularly Spencer’s kiss that lets him know it, but he can feel how special this was to him, to the both of them. He reluctantly pulls away, brushing a tousled lock of hair from his lover’s face. “Hope that kiss means I didn’t disappoint you.”
With a small laugh, Spencer replies, “The only way you could disappoint me is if you tell me you’re not ready for round two.”
