Dean has been in Castiel's bedroom for forty-one minutes. He’s been watching the time pass on the clock perched above Castiel's desk, its soft blue digits flickering like a taunt. Every minute that ticks by only confirms one thing.

Castiel still hasn’t looked at him.

Not once.

Castiel is sitting at his desk, grading with mechanical focus, glasses sliding down his nose in that way Dean knows he won’t bother to fix until they’re nearly falling off. His red pen moves across the page with quiet, lethal precision, leaving behind strokes that carve deep into clumsy arguments and poor grammar. The margins of the paper are already a warzone of neatly-worded disappointment.

“Are you really going to ignore me all night?” Dean finally says, his voice casual enough to sound like he’s joking. But it’s not. Not really. There’s something tucked underneath it, something raw and irritated, like a frayed wire just barely keeping from sparking. Maybe it’s loneliness. Castiel doesn’t let himself think too long about that.

“I’m working,” Castiel replies evenly, eyes still on the page. “I told you I’d be grading.”

Dean lets out an exaggerated sigh, dragging the sound out like it owes him something. “Yeah, but it’s rude. I came all the way here to see you.”

Castiel carefully places his glasses down, pinching the bridge of his nose like this might stop the headache forming behind his eyes. “You also said you wouldn’t show up uninvited anymore.”

“I lied,” Dean says immediately. Castiel hears the shift of weight behind him, the soft groan of the mattress as Dean rearranges himself. “Let’s be real. We’re kind of past the whole invitation thing.”

Castiel's pen hovers above the next paragraph, just for a breath, before he resumes grading. Run-on sentence. Weak thesis. Irrelevant citation. A bold claim with no source, just vibes. This paper, at the very least, had the decency to pretend it belonged in this room. Dean, on the other hand, had arrived like he always did, loud, stubborn, and absolutely refusing to take a hint.

He glances back for half a second. Dean is sprawled out on the bed like he paid rent here, one leg hanging off the edge, the other bent at the knee like this is his room and Castiel is the guest. He’s wearing a soft-looking Henley that’s far too big for him, sleeves pushed to the elbows, collar slightly rumpled. His boxers are gray. That detail annoyingly insists on being noticed.

Not that Castiel is looking.

He isn’t. He doesn’t need to. He’d already seen it all the moment Dean walked into the room, had watched, without watching, as Dean peeled himself down to comfort and bare skin. Castiel had bitten the inside of his cheek until the pinch of pain held him still, kept the heat rising beneath his skin from reaching his face.

Dean had walked in like the idea of modesty was beneath him and stretched across Castiel's bed like temptation personified. And now he’s just lying there, utterly unbothered, mouthing off into Castiel's pillow as if this were his room, his space, his right.

Castiel forces his eyes back to the paper in front of him.

The truth is, he doesn’t actually mind Dean being here. At least not at first. Not until Dean figured out that Castiel liked him. Liked him as a person, found him amusing, maybe even endearing on occasion. Castiel had meant it platonically, of course, maybe with a few stray moments that bordered on fondness. But Dean had taken that fondness, misread it completely, and decided it meant more. And now here they are, stuck in this quiet, messy orbit that neither of them seems willing to break.

Which would be complicated enough on its own, but this isn’t just about affection or miscommunication. This is about boundaries, and professional ethics, and the fact that Castiel absolutely should not be having anything even remotely resembling a personal relationship with one of his former students. He had spent a full hour in a meeting with the council after Dean’s first semester, arguing, pleading really, that the kid needed to be placed in any other professor’s section going forward. Preferably one without a pulse.

He’d thought that would be the end of it.

He should have known better.

Because one thing about Dean Winchester is that he’s persistent to the point of self-destruction. Once he’s decided on something, he sinks his teeth in like a terrier and refuses to let go. Castiel has seen him chase after things with more loyalty than self-preservation, whether it’s a losing argument, a broken vending machine, or a man who clearly doesn’t have the emotional bandwidth to deal with him.

And from that day forward, Dean had made it very clear that Castiel was not “Professor Novak” anymore. Not “Castiel,” not even “sir,” which would have been inappropriate but technically correct. Just Cas. Always Cas. Like they were friends. Like there were no rules to this.

Castiel underlines the word “unclear” and moves to the next page.

Behind him, Dean yawns loudly and flops onto his stomach with the weight of a man who has never considered the concept of boundaries. “I’m just saying,” he murmurs into Castiel's pillow, muffled and dramatic, “you’re ignoring me like I’m a ghost. Which I’m not. I’m very alive. Warm-blooded. Devastatingly charming.”

“You’re distracting,” Castiel says, not looking up.

“Same thing,” Dean replies.

Castiel doesn’t answer. It’s easier not to. Easier to pretend this is something harmless. Easier to keep grading than to admit how much Dean’s presence changes the shape of this room. How, for all his annoyance, he hasn’t once told Dean to leave.

He’s not going to, either.

And Dean knows it.

“You could at least offer me something to drink,” Dean says as he fidgets with the lamp on the nightstand this time, flicking it on and off like he’s trying to summon something. Then he picks it up and turns it over in his hands, inspecting the base like it holds secrets. The clicking noise alone is enough to drive Castiel closer to the edge, but it’s the growing throb behind his eyes, the one that comes hand-in-hand with age, stress, and Dean Winchester that truly seals it.

Dean’s voice cuts through again, casual as anything. “Isn’t that what people do before fucking these days?”

Castiel doesn’t look up. “You didn’t come over to fuck.”

“No,” Dean replies easily, all false innocence and dangerous optimism. “But I’m not ruling it out.”

Castiel closes his eyes, and sets the pen down with deliberate care. He pinches the bridge of his nose, already bracing for the headache that has been steadily growing since Dean walked in unannounced and barefoot. “What do you want, Dean.”

It’s not a question, not really. It’s more like a resigned plea.

Dean sits up, folding his legs beneath him like he thinks he’s being polite. “Some acknowledgment of my presence would be decent,” he says, as though barging into someone’s private space without invitation is just a minor social faux pas.

Castiel finally turns his head, just enough to look at him. Dean is sitting there on the bed like a sin draped in linen, head tilted, expression unreadable. His legs stretch long across the sheets, all tan skin and lazy muscle, his shirt riding up slightly at the hip. He is, unfortunately, beautiful, too much gold, too much confidence, a soft pink mouth that has no business looking so sincere. His eyes are jaded, but sharp, observant in a way that irritates Castiel. There’s a small mole on his ribcage. He shouldn’t know that, and yet he does.

“Do you have a paper you want feedback on?” he asks dryly.

Dean grins. “I can give you something else to give feedback on.”

Castiel does not dignify that with a response.

He really isn’t as prudish as he seems right now. He’s had his share of mistakes, of indulgences, of people who took up his bed and left nothing behind but body heat and the faint smell of their shampoo. But tonight is not for indulgence. Tonight, unfortunately, is for work. There’s a stack of poorly argued essays on his desk, and he has a deadline. What he does not have is time to entertain the very pretty, very underdressed young man who is clearly making it his life’s mission to distract him.

Besides, the optics are terrible.

From the outside, it looks exactly like what it is. A professor with his former student, half-naked on his bed, offering suggestive remarks and dangerous charm. And while Dean might thrive on audacity and chaos, Castiel cannot afford the fallout. He doesn’t have a safety net to catch him if he falls. He has no history of rebellion to romanticize, no parental resentment to wear like a badge of honor. He has this job, this reputation, and the constant, bone-deep awareness that one misstep could end it all.

Dean, on the other hand, has the luxury of recklessness. He can afford to crash and burn. Castiel cannot.

Still, Castiel doesn’t turn fully back to his work. His body remains angled toward the bed, drawn despite himself.

Dean catches the hesitation. His eyes flicker, his mouth quirks just slightly at the corner, like he’s caught Castiel in the act of almost caring. Then he shrugs, too light, too casual. “Your attention,” he says. “Affection, maybe. Praise, if you’re feeling generous.”

He says it with a grin, but it doesn’t quite reach his eyes. Castiel watches him for a long second, wondering as he has many times before, how much of Dean’s boldness is armor, and how much of it is just a dare to see who will finally take him seriously.

“Praise,” Castiel repeats, as if tasting the word and finding it lacking. “You want praise.”

“You could be nice to me,” Dean replies, his voice innocent in the most deliberate, dishonest way. His eyes are wide, just a little too wet, and there’s a sliver of teeth showing where his lips part into something that could be mistaken for vulnerability. Castiel wants, absurdly, to kiss him and insult him in the same breath. He wants to be generous and cruel, to give Dean everything and still make him work for it. Mostly, he just wants to keep him right there, in this room, within reach.

With a sigh, Castiel turns his chair slowly, finally facing him. “It’s difficult to praise someone whose greatest accomplishment tonight is successfully trespassing.”

“I knocked, sweetheart,” Dean says, scandalized. “You just weren’t listening.”

Castiel lifts a single eyebrow. “So you took it upon yourself to let yourself in.”

“You left me no choice,” Dean replies with a shrug, as if he’s explaining something entirely reasonable. He begins to cross the room, not rushed, not dramatic, just steady, casual, barefoot. His footsteps are soft against the wood floor, but his presence is anything but subtle. “You keep a key where you know I can see it.”

Castiel says nothing, but the truth of it hovers in the space between them. He does keep a spare key there. And Dean had, of course, seen it the very first time he came over, catalogued it with that sharp, curious mind of his, and then waited for the perfect moment to make use of it. Which, evidently, was tonight.

Dean stops in front of him, leaning a hip against the desk like he belongs there. His eyes drop briefly to the essays strewn across the surface, then flick back up to Castiel, daring him to care more about comma splices than about him.

Castiel breathes out through his nose. “If I give you a moment of my time,” he says, voice low, “will you go home?”

Dean’s mouth twitches. He pretends to consider it, tilting his head like he’s weighing a serious decision. “No,” he says brightly. “But it might make the evening more pleasant. For both of us.”

There’s no logic left to argue with. Castiel looks at him properly now, lets himself see it all. The mess of Dean's hair. The faint flush rising in his cheeks. The slight tremor in his hands that Dean tries to hide, though Castiel sees it anyway. It’s not fear. Not nerves. It’s the weight of everything he refuses to say out loud.

Castiel already knew, the second Dean stepped through the door tonight, exactly where this would end. He sighs again, softer this time, and leans back slightly in his chair, his eyes steady on Dean’s.

“Come here, then,” he murmurs.

Dean doesn’t hesitate. He climbs into Castiel’s lap like he’s done it before, which, of course, he has, more times than Castiel would like to admit. His thighs slide into place around Castiel's hips with practiced ease, all warmth and weight and intention. The air between them shifts again, thicker now, heavier, and Castiel feels the heat rising in his chest.

Dean’s skin is warm against him, flushed and soft, and his pulse flutters visibly in his throat. It’s a fast rhythm, betraying the calm he’s trying to wear like a shield.

Castiel wants to touch him. Not in the obvious way, though that temptation is always there. He wants to press his fingers to the spot just below Dean’s jaw, feel the heartbeat stuttering under the skin. He wants to trace the line of his neck and say something that will make Dean flinch, or smile, or stay.

“I mean it. Only a moment,” Castiel says, though the promise is already unraveling. His hands are sliding up the outside of Dean’s thighs, slow and steady, the heat of his palms bleeding easily through the thin cotton. His touch is deliberate, measured like everything else about him, as if discipline alone might hold back the inevitable.

Dean hums in response, his eyelids heavier now, lashes fluttering low. He shifts slightly in Castiel's lap, and Castiel's thumbs drift higher, brushing just beneath the hem of Dean’s boxers where the skin is soft and warm and too easily affected.

“You should really be more careful with your key,” Dean murmurs, voice lilting with fake innocence. “If you don’t want people breaking in. I could’ve been a murderer. Or a cannibal. Or something worse.”

Castiel lets out a quiet, unimpressed, rumble sound, one that falls somewhere between a sigh and a hum. He lifts one hand to Dean’s face, fingertips grazing his cheekbone before his thumb presses lightly along the line of his jaw. Dean goes still at the touch, his lips parting without needing to be told. It's instinctive, like a door opening the moment someone knocks.

Castiel brushes his thumb against Dean’s lower lip, slow and lingering. Dean’s breathing stutters, just faintly, and Castiel watches the way his mouth yields so easily, like it was made for this. He presses a little deeper, until his thumb slides over smooth teeth. Small and neat. Almost dainty, if such a word could ever be applied to Dean Winchester.

“Not with these teeth,” Castiel says quietly, almost fondly. A smile pulls at the corner of his mouth.

Dean shudders beneath the touch, and the flush on his cheeks blooms deeper, traveling down his neck in waves. He doesn’t pull away. He doesn’t even blink. His eyes stay fixed on Castiel, wide and glassy, like he's caught between worship and want and doesn’t know how to land on either.

Maybe it’s the intimacy of it. Not the suggestive closeness, but the strange, quiet tenderness of someone gently tracing the inside of your mouth, like you’re something fragile, or precious. Maybe that’s why Dean shifts again, hips restless now, his fingers curling tighter into the fabric of Castiel's button shirt. There’s a faint tension in his shoulders, like he’s holding something in. Something big.

Castiel doesn’t move yet. He just holds Dean there, thumb resting inside his mouth for a moment longer, watching him like a scholar watching the slow unravel of a hypothesis he already knew was true. When he finally pulls away, his hand drops lower, fingers ghosting down Dean’s throat until they settle lightly over his pulse.

Dean’s heartbeat is frantic. It flutters beneath Castiel's fingertips like it’s trying to escape.

Castiel leans in, just enough to feel Dean’s breath against his own mouth. It’s warm and ragged and uneven, like every inhale is borrowed time.

“You don’t want to hurt me, Dean,” Castiel murmurs, soft as sin, coaxing and close. “You like my attention too much.”

Dean doesn’t answer. He breathes like someone who forgot how. Too fast. Too shallow. His chest rises and falls as though he’s resisting the urge to collapse forward. His eyes stay locked on Castiel's, burning with something that looks suspiciously like desperation wrapped in defiance.

Castiel doesn’t kiss him. Not yet.

He lets the moment stretch out, held in the fragile gravity that always seems to settle between them when things go quiet. His hand remains at Dean’s neck, light but unyielding, fingertips brushing against the hot thrum of his pulse. It flutters under his touch, rapid and uneven, like it’s trying to outpace the moment itself. Castiel wonders, briefly, what it would feel like to lean in and mouth at that spot. To drag his teeth along it and watch Dean shudder. To press until the beat jumped, frantic and exposed.

He’s done it before. More than once.

It hadn’t taken many encounters for them to fall into this pattern. A few reluctant conversations. Two or three too-long glances. Then the night Dean showed up at his door under the pretense of needing to “vent”, a word that, in Dean-speak, translates to emotional sabotage followed by unapologetic physical escalation. The stories had come fast after that. Complaints about his family, about expectations he never asked for, about responsibilities he didn’t want but couldn’t escape. Castiel had listened. Then kissed him quiet. Then kept doing it until he realized that Dean’s voice, grating and relentless in conversation, was significantly more bearable when he was whining under Castiel instead of whining at him.

Not that he ever stopped talking.

“You’re such a handful,” Castiel murmurs, not intending to say it out loud. It slips out anyway, too soft around the edges.

Dean blinks, thrown by the tenderness. Then, predictably, he smirks. “That your way of saying I’m irresistible?”

“No. It’s my way of saying you break into my house and climb into my lap like a cat in heat,” Castiel replies flatly.

But he doesn’t tell him to get off.

Dean’s grin widens, sharp and a little uneven. “Yeah, but you didn’t say no.”

“I should have.”

“You always say that after,” Dean points out, matter-of-fact.

Castiel hums in agreement, noncommittal. His other hand slips under the hem of Dean’s shirt, fingertips brushing warm skin. The contact is casual, exploratory, but the shiver it draws from Dean is anything but.

“Take it off,” Castiel says quietly.

Dean raises an eyebrow. “You first.”

Castiel does not oblige. Instead, he reaches behind Dean, rummaging through the mess of papers and pens on his desk until his fingers close around something small and plastic. He brings it into view between them.

Dean squints. “What’s that?”

Castiel turns it so Dean can see. A red plastic stamp, the kind usually reserved for elementary teachers grading spelling quizzes. The cheerful words You’ve done well are printed inside a tiny cartoon starburst.

Dean stares at it, then at Castiel. “You’ve got to be kidding.”

Castiel doesn’t answer. He flips the stamp back over and presses it firmly against the inside of Dean’s thigh, just below the hem of his boxers.

Dean jerks slightly, breath catching in his throat. “What the—what the fuck was that?”

“You don’t get a gold star,” Castiel says calmly, pressing his fingers to the ink-marked skin. “You broke into my house.”

He keeps his hand there, thumb brushing along the edge of the fresh red stamp like he’s considering giving it a border. His touch is slow, thoughtless in the way only something deeply focused can be. When he looks up at Dean again, his gaze is unreadable.

“This one’s for sitting still.”

Dean makes a strangled noise, somewhere between indignation and arousal, but he doesn’t move. His thighs stay open, legs still, the stamp smudgeless and untouched. When Castiel drags his thumb over it again, slower this time, the sound Dean makes is closer to a gasp.

Castiel doesn’t say anything about it. There’s no need. He lets his hand wander lower, sliding between Dean’s legs, watching the defiance in Dean’s face melt into something closer to desperation. His breath stutters. His fingers clench around the front of Castiel's shirt like it’s the only thing anchoring him to the room.

Castiel had bought the stamps with good intentions. He’d thought they might be a gentle counterbalance to the occasional academic brutality of his feedback. A harmless gesture. Encouragement. Positive reinforcement.

Apparently, they’re multipurpose.

Dean leans in suddenly, closing the space between them, resting their foreheads together. His breath is shaky, his voice even more so. “If you’re gonna touch me,” he whispers, hoarse and quiet, “do it like you mean it.”

Castiel smiles, teeth catching behind his lips. “You’ll get another stamp if you ask nicely.”

Dean exhales, eyes fluttering shut. “Fuck.”

Dean’s knee keeps knocking into the edge of the armrest, one leg tucked up awkwardly beneath him, the other tangled with Cas’ in a way that clearly isn’t comfortable for either of them. But Dean doesn’t seem to care. He’s sprawled out like the chair was built for this, for him, like he’s entitled to the space and everything in it, including Castiel.

His mouth moves over Castiel's with that same slow, weighty intent he always has, like kissing is something that should feel deliberate. Like he’s proving a point. Castiel lets him. For now. Dean tastes faintly of smoke, the artificial kind that clings to the edges of nicotine gum or cheap breath mints, which tells Castiel that whatever he smoked before arriving wasn’t entirely meant to be hidden. His breath is warm and unhurried. Castiel doesn’t mind it.

His hand is already under Dean’s shirt, palm settled over the curve of his ribs, thumb drawing idle shapes into the soft heat of his skin. Dean’s fingers are threaded through Castiel's hair, gentle but possessive, like he wants to pull him closer without having to admit that’s what he’s doing.

When they finally part, it’s only because they have to. The air between them has thinned to nothing.

Dean rests his forehead against Castiel's, his breathing uneven. His lips are swollen, slightly damp, still flushed with want. His gaze is heavy-lidded and lazy, but his mouth pulls into a sharp, cocky grin.

“You’re getting better at this,” he murmurs, the words low and teasing. “Less stiff.”

Castiel exhales through his nose. “I’ve kissed before you,” he says plainly. “I’ve fucked before you. You didn’t invent this.”

Dean pulls back just enough to meet his eyes, still grinning. “Doubtful,” he replies.

He shifts his leg, just enough for Cas to see the inside of his thigh, where the little red outline of the stamp is visible. Smudged slightly, but unmistakable.

Castiel regards it for a moment longer than necessary, then glances at the clock on the table behind Dean’s shoulder.

“Don’t you have an early class tomorrow?” he asks.

Dean makes a sound like he’s just been mortally wounded. “Why would you say that to me?”

“Dean.”

“It’s like you actively avoid fucking me,” Dean complains, flopping back slightly in theatrical defeat.

“It starts at seven,” Castiel says, voice perfectly even. He doesn’t have to guess. Of course he knows.

“Perfect,” Dean replies without missing a beat. “Then I’ll be late with intention.”

“You need to go,” Castiel says, but even he hears the weakness in his tone. It comes out soft. Tired. Not even pretending to mean it.

Dean hears it too. He always does. He’s like a bloodhound when it comes to Castiel's lack of resolve when it comes to him, and Castiel has learned, far too quickly, that Dean is always ready to pounce the second he catches a scent of hesitation.

“Going would be lazy,” Dean says as he leans in again, slinging an arm across Castiel's broad and strong shoulder like it’s his new home. “It’s the coward’s way out. Avoiding discomfort for comfort’s sake. Very pedestrian.”

Castiel gives him a squinting look, the one he gives when he thinks someone suddenly grows a second head. “Attending class is pedestrian?”

“Yes,” Dean says with unwavering confidence. “Everyone does it.”

“That’s not how—”

“I’m an innovator,” Dean cuts in, nodding solemnly. “Not a sheep. And I’m fucking my professor, so I think I’ll be alright.”

Castiel doesn’t immediately respond to that. Not because he’s shocked. He’s long past the point of being shocked. It’s just that Dean has been on academic probation for almost the entire year. Three close calls. Too many late assignments. More absences than anyone’s supposed to survive. Bobby, Ellen, and Sam, along with Castiel himself have used every contact they could to pull Dean through those doors and keep him there. The system is barely tolerating him.

And now, that same system is sitting in Castiel's lap.

The thought that Dean might have tried this tactic, sleeping with a professor before Castiel, slips into his mind. It sours immediately. He doesn’t let it stay.

“I’m not even your professor anymore,” Castiel says, flat and final. He gestures vaguely between them. “This doesn’t count toward your academic survival.”

Dean doesn’t flinch. He just hums, then reaches up and twists a finger through the longer hair at the back of Castiel's neck. His smile is smaller now. Quieter.

“You could still put in a good word for me.”

Castiel stares at him for a moment, mouth pressed into a thin line like he’s weighing something. Then, with a small tilt of his head, he murmurs, “You can stay. If you’re good.”

Dean goes very still.

It only lasts a second, but Castiel sees it, the shift. The flicker of surprise. Dean’s body readjusts slowly, fingers curling tighter into the fabric of Castiel's shirt, his mouth twitching into something smaller and softer than a grin.

“Define good,” Dean breathes, barely above a whisper.

Castiel slowly reaches for him. Two fingers beneath Dean’s chin, guiding it upward. Dean’s mouth parts instantly. He isn’t smiling anymore. He just looks pliant. Breathless. Like something you could press your thumb into and leave a dent. His eyes are blown, glassy with heat, lashes lowered.

Castiel drags his fingers across the flat of Dean’s bottom teeth. Gentle. Testing.

“You can’t use these,” he says, voice low.

“I won’t,” Dean says quickly. The words tremble. He shudders as he says them, a full-body flinch that betrays how close he already is to unraveling.

Castiel exhales through his nose, slow and steady, like it’ll help keep his thoughts straight. It doesn’t. He reaches without thinking, hand curling around the side of Dean’s neck, thumb pressing into the soft place just beneath his jaw. The reaction is instant. Dean leans into it like it’s instinctive, like he was only half-present until Castiel touched him, and now he’s anchored.

Castiel can feel his pulse there, a fast little thrum under skin that’s too warm. It flutters against his thumb, barely contained, like it’s trying to give him away. Dean never quite manages to hide that. Not from him. Castiel brushes his thumb across the rhythm, and watches the moment Dean’s breath falters.

Dean’s eyes go heavy, lashes casting soft shadows across his cheeks. He doesn’t flinch. Doesn’t pull away. If anything, he leans in closer, like this is something he’s been quietly hoping for. His fingers tighten against Castiel's shoulders, not demanding, just holding on, as if bracing himself for the answer to a question he hasn’t found the nerve to ask yet.

Castiel tilts his head slightly, studying him, then speaks, voice low and even. “See? You’re good for me, Dean.”

The word slips out like a test, and Dean reacts like it hits something raw. His shoulders twitch, a tremor runs through the muscles in his thighs, and for a second he stops breathing altogether.

Dean swallows hard, throat working visibly. “Careful,” he says, voice thin and hoarse at the edges. His gaze is still lowered, like he doesn’t trust what will happen if he meets Castiel's eyes. “I might start believing you.”

Castiel hums, like the thought doesn’t scare him. “You are,” he replies, quieter now. “You’re being good now.”

That does something. Dean shivers, full-body and immediate, like the words wrap around his spine and settle under his skin. It’s not just what Castiel says, it’s how he says it. Calm, like it’s fact. Warm, like it’s meant to be carried. He’s steady in a way Dean is still trying to understand. Still trying to trust.

The silence stretches, thick with whatever lives in the space between trust and want. Dean doesn’t speak. He doesn’t need to. He’s sitting there like a prayer someone forgot to say out loud.

Castiel lets the moment hang, then adds with the kind of smile that makes Dean nervous, “Should I reward you again?”

Dean’s breath catches. His reaction is subtle but unmistakable, his thighs tense where they bracket Castiel's, his fingers curl against his chest like they’re trying to hold in the tremble.

He blinks, slow. Swallows again. “Shut up,” he mutters, barely more than a whisper.

He says it like it’s a shield, but it’s soft, almost reverent, and Castiel doesn’t miss the way his grip never loosens. Like he doesn’t actually want him to stop. Like he wants everything. Just not all at once.

Castiel's hand finds its way back to Dean’s waist, his fingers curling with familiarity like they’ve always belonged there. His thumb moves in slow, calming circles just along the edge of Dean’s hipbone, warm and steady. Then, with the same quiet deliberation, Castiel presses the stamp to his skin. It clicks softly, barely audible, but it still feels loud in the charged silence of the room.

A fresh mark blooms against Dean’s thigh, bold and clear, the ink stark against his skin.

You’ve done well

Dean’s breath stutters, catching in his throat like his lungs are trying to hold onto it. For a second, he goes completely still. He’s not playing coy this time. He’s processing it, whatever heat, whatever weight those three words just carved into him. He looks like someone trying not to fall too fast in a dream.

When he finally exhales, it’s a little ragged around the edges. His hands tighten just slightly on Castiel's shoulders, not clutching, but definitely holding. He’s staring somewhere near the middle of Cas’ chest, like if he makes eye contact, something will short-circuit.

Castiel doesn’t comment on it. Not right away. He just watches the color rising at Dean’s neck, a slow, creeping pink that betrays him more than anything he’s said so far.

Then, softly, with just a hint of amusement curling at the edges of his voice, Castiel murmurs, “Look at you. That’s all it took for you to be quiet?”

Dean breathes in again, just a breath, not a word and still doesn’t move. Still doesn’t look at him. His silence feels like an answer in itself.

Castiel reaches up and gently lifts Dean’s chin between two fingers, coaxing him into eye contact. His touch is careful, not demanding, but firm enough to leave no room for retreat. “If you keep being good,” he says, voice dipping to something quieter now, more intimate, “I might give you the gold one.”

That does it. Something in Dean’s expression slips, barely, but enough. There’s a flicker of vulnerability, something unguarded that floats up just long enough to be seen. His mouth parts slightly, lips wet as he swallows, and his gaze dips away again like he’s not sure he wants to be caught looking the way he feels.

“Don’t promise what you won’t give, Cas” Dean says, and the bravado in his voice is almost convincing. Almost. But it falters at the end, the roughness breaking apart like old paint.

Castiel runs his thumb along the edge of Dean’s jaw again, brushing over the soft, stubborn stubble that always seems to grow back before it should. He tilts Dean’s face back up, a little slower this time, holding him there with a kind of quiet reverence.

“I always keep my promises,” Castiel says simply, like it’s a truth that doesn’t need decoration.

Dean finally meets his eyes again. There’s no more posturing left. No more sharp remarks to cover the cracks. His gaze is open, trembling at the corners, and full of things he hasn’t figured out how to say. It’s not begging, not exactly. But it’s close. It’s hope wrapped in caution. A silent plea for Castiel to mean it, this time. Really mean it.

Castiel watches him for a long, unhurried moment. The silence sits heavy between them, not awkward but dense, like something about to tip over. The room feels smaller than it did a minute ago, warmer too, the air thick with the strange, slow-burn gravity of ink freshly stamped into skin. Dean still has both hands fisted in the hem of his shirt, knuckles pale, like letting go might make the moment disappear. His pupils are blown wide, almost black, and his cheeks are still tinged pink, as if the compliment were something physical that had touched him and stayed.

Castiel tilts his head slightly, quiet and observant. “You’re trembling,” he says, voice low enough to be mistaken for something private.

Dean doesn’t answer right away. His jaw works for a second like he’s trying to decide between pretending he didn’t hear or pretending it doesn’t matter. Then he lifts his chin, pulling together a grin that looks more like a smirk that forgot what it was supposed to cover.

“Maybe it’s cold in here,” he replies, though his voice betrays him, it’s lighter than usual, a little hoarse, all the usual bite softened at the edges. “Or maybe your good boy routine is catching. Ever think of that?”

Castiel hums, pleased. The corners of his mouth twitch up, the kind of smile that happens before he even realizes it’s there. He slides his hands up Dean’s thighs again, slow and certain, like he’s tracing a familiar map. His thumb brushes the new stamp, gently circling over it, not pressing hard, just enough to remind Dean it’s there. The ink is still sharp, the words bright and clear, and Castiel can tell by the way Dean won’t quite look at him, by the way his jaw tightens, that it’s landed somewhere deep.

“It still isn’t too late to go home and make your class early,” Cas says eventually. His voice is soft, casual, like it’s a real suggestion, even though they both know it isn’t.

Dean shakes his head almost immediately. He leans in instead, burying his face against Castiel's shoulder, his lips brushing the fabric of Castiel's shirt like an afterthought. His voice comes muffled, dry with mock seriousness. “Not going is an act of self-preservation. I refuse to subject myself to institutional mediocrity.”

Castiel laughs, a low, genuine sound that rumbles in his chest. His thumb presses a little firmer against the ink, just to see Dean react, and sure enough, Dean flinches a little, breath catching in his throat.

“Is that so?” Castiel asks, clearly entertained.

Dean lifts his head again, but only far enough to meet Castiel's gaze. His eyes are sharp but fond, and his mouth curves just enough to be considered sincere. “It’s more productive to be here,” he says matter-of-factly. “I’m learning to accept positive reinforcement. I’m building character. I’m…” He trails off mid-sentence, distracted by the feeling of Castiel's palm spreading wider across his thigh, warm and steady, thumb still working slow circles over the stamp like he’s trying to imprint the message deeper.

“You’re what?” Castiel asks, not pushing, just curious.

Dean exhales a quiet sound, somewhere between a scoff and a laugh, a little flustered. But he doesn’t look away. His cheeks flush again, high and warm, but he holds his ground. “I’m being good for you,” he says. “Isn’t that what you wanted?”

And just like that, something tugs inside Castiel, sharp and fond, like a thread pulled tight in his chest. There’s a flicker of disbelief at how easy it is to care this much, how easy it’s always been with Dean, even when they’re fighting, even when Dean is being impossible.

He leans in until their mouths nearly brush, his breath mingling with Dean’s, and says it like a secret he’s been keeping too long. “It is.”

The quiet that follows isn’t empty. It hums. It crackles with everything unsaid, everything too new or too honest to name. Castiel doesn’t pull away. He lets himself hold Dean for a while longer, steady and solid, until the shiver in Dean’s hands settles, until his breathing finds a rhythm again.

Eventually, and surely, the stamp will fade. But this, this moment, Castiel intends to keep.

Dean's breath hitches, sharp and helpless, when Castiel's fingers trail higher, slipping just under the hem of his boxers. He doesn’t even try to hide the shiver anymore. If anything, he leans into it, his thighs falling open in a slow, unconscious invitation. There’s a flicker of hesitation, maybe instinct, but it dies quick under the ache. He wants this, wants him, and his body knows it before his brain finishes the thought.

Castiel feels the subtle clench of muscle beneath his fingertips, the way Dean’s abs tense like they’re bracing for impact. And maybe they are. But Castiel has no plans to rush. Not when Dean’s already this pliant under his hands, this open. He lets the silence stretch, taut and trembling, lets the weight of it press down between them. His eyes drift lazily, first to Dean’s eyes, glassy with need, then to the faded ink smudged slightly along his skin, and finally to the flush creeping down his chest in blotchy waves.

“You’re still being good,” Castiel murmurs, voice like warm velvet, like a rum poured slow over bare skin. It lands in Dean’s chest like a hand pressed flat and heavy, possessive in all the ways Dean aches for.

Dean’s mouth parts around a shaky breath. “Then do something about it.”

Castiel obliges with a hand slipping beneath his shirt, rough fingertips skimming up the warm, trembling plane of Dean’s stomach. He kisses him hard, slow at first, but it deepens quick, greedy, biting at his lower lip until Dean whimpers, low and broken, like the sound was pulled right out of his lungs. It’s almost pathetic. Castiel kisses him harder for it.

The pace turns hungry. Castiel's hands roam with intent now, possessive in the way they map Dean’s chest, his sides, dragging over ribs and scars and muscle like he’s trying to memorize every part of him by feel alone. He mouths along Dean’s jaw, trailing heat down his neck, his stubble leaving pink streaks behind like he’s signing his name with every pass of his mouth.

Dean gasps, clinging to Castiel's shoulders with shaking hands. His hips twitch up in little, desperate jerks, looking for friction, any friction, and finding none. “Please,” he breathes, voice cracking beautifully in the middle, and there’s no telling if he means the touch or the words or both, likely both.

Castiel pulls back just enough to study him. His eyes are darker now, heavy-lidded and unhurried. “What do you want, Dean?”

Dean’s face burns crimson, but he doesn’t shy away. If anything, he leans in closer, reckless with it. “Praise me,” he whispers, all raw nerve and honesty. “Touch me.”

That earns him a real smile, crooked, knowing, entirely unfair. “Good boy,” Castiel says, like it’s the easiest truth in the world. And then his hand slips past the waistband, curls around him in one smooth, devastating motion.

Dean chokes on a moan, head tipping back, mouth slack, body lurching helplessly into Castiel's grip. He grabs at Castiel's shirt, yanking him in close, frantic like he might come apart without the contact. Castiel strokes him slow, measured, like he’s enjoying the show. And he is. Every twitch, every bitten-off sound, every stifled gasp and whisper of Castiel's name, it’s all better than he could have imagined.

“You take everything so well,” Castiel murmurs, voice barely audible over Dean’s panting. “So good for me.”

Dean’s thighs tremble around him, back arching as he tries and fails to keep himself quiet. “Want you,” he breathes, too honest now to care about what he sounds like. “Need you.”

Castiel kisses him again, harder this time, like the answer is in the way their mouths crash together. Then he shifts, one smooth, practiced motion, and lifts Dean up just enough to ease him flat onto the desk. The stack of ungraded papers scatter across the floor. Neither of them look down.

Castiel stands between Dean’s spread thighs, hands never leaving him, gaze steady and wanting and so damn fond it hurts.

He presses another stamp carefully onto Dean’s another inner thigh once his legs have fallen completely open, loose and trembling. He doesn’t miss the way Dean’s breath hitches sharply, how a small whine curls in his throat and dies behind his teeth as he bites his lip.

“There it is,” Castiel murmurs, voice warm and unhurried as his fingers press into the soft skin just above the mark. “That one’s for being good so far.” He pauses, nails dragging gently along the curve of Dean’s thigh. “But I want to hear you.”

The stamp gleams like fresh sin, inked in bright red and framed by skin gone flushed and oversensitive. It sits there like a confession no one forced out of him. Castiel runs his thumb across it slowly, reverent in a way that feels cruel. Dean's head falls back against the hard edge of the desk, mouth open, throat bared, his last line of pride already gone, stripped away by nothing more than touch and attention.

He doesn’t nod. He doesn’t speak. But Castiel sees it, feels it, in the way his hips twitch helplessly upward, in the way his chest trembles with shallow, unsteady breaths. The obedience isn’t reluctant anymore. It’s needy. Full-bodied. Pure.

Castiel watches him like a scholar might watch a miracle, eyes fixed on the trembling curve of Dean’s lips, the way his eyelashes flutter with every soft drag of Castiel's thumb. He presses along the outline of the stamp again, watching as Dean gasps, chest stuttering, thighs quivering with restraint and raw need. It’s beautiful. It’s filthy. It’s his.

He leans in, mouth brushing against the shell of Dean’s ear, voice dropping to a whisper. “Do you know how pretty you look right now?”

Dean shakes his head, just barely. His lips part, wet and trembling, and when he speaks, the sound is nothing more than a whisper held together by desperation. “Cas—please…”

Castiel's hand is everywhere. One trails up Dean’s trembling side, brushing beneath his ribs where he’s soft and too sensitive. The other finds his waist again, holding him steady. His thumb glides across Dean’s jaw, presses against his cheek until Dean's mouth drops open, slack and ready.

“Open for me,” Castiel says, quiet and hungry.

And Dean does, without hesitation. Tongue glistening, eyes fluttering shut, his whole body answering before his mind catches up. Castiel slides two fingers into his mouth, slow and deliberate. Dean’s lips seal around them like muscle memory, sucking with a slow, filthy rhythm that makes Castiel's breath stutter. The wet sounds echo in the stillness of the room, obscene and perfect.

Dean moans softly around his fingers, and Castiel lets him keep it up a moment longer, just long enough to feel the heat curling low in his stomach, before pulling his fingers free with a wet pop. He drags them down Dean’s chest, leaving behind a slick trail that cools in the air, turning Dean’s skin into a canvas of want.

He shoves the shirt up, baring Dean’s torso, then slides those rough fingers down, teasing along the line of his boxer briefs. The fabric clings, damp and straining, sticking to him like it’s desperate too.

Castiel watches, biting back a groan. “So good for me,” he murmurs, half to himself. “You like this. You need it.”

Dean makes a broken sound in the back of his throat, face burning. The flush spreads down his chest like spilled wine, a perfect match for the color stamped into his thighs. He nods once, frantic, choking on the words. “Please—just…”

Castiel cuts him off with a firm press of his palm over the bulge in his briefs. Dean cries out, hips jerking, body straining into the pressure like he’s already halfway there.

“Tell me,” Castiel says, watching the tremble in his legs, the way his hands clutch at the edge of the table like it’s the only thing keeping him grounded. “What do you want, Dean? Use your words.”

He knows what Dean wants. He’s known it since the first stuttered breath, since the first flushed, flinching glance. But he wants to hear it. He wants Dean to say it out loud, to give it up willingly.

Dean swallows hard, his voice cracking on the edge of it. “Touch me. Please. Just—fuck, Cas—touch me.”

Castiel smiles, dark and satisfied. “That’s my good boy.”

His hand slips beneath the waistband, slow and smooth, until his fingers curl around Dean’s cock again, hard and hot and leaking already. Dean lets out a raw, desperate moan, hips bucking helplessly into Castiel's grip, chasing the friction like he’s starving.

The touch starts slow. Painfully slow. Castiel strokes him with a maddening sort of precision, like he has all the time in the world and absolutely no intention of speeding things up. His grip is firm but unhurried, thumb circling the tip in slick, lazy passes that make Dean twitch and swear under his breath. It's not enough. It’s nowhere near enough.

Dean arches into the touch instinctively, back bowing, thighs trembling where they fall open. His whole body is flushed, sweat-slicked and shivering, one arm flung over his eyes like it could somehow hide the wreck he’s turning into. He doesn’t want to be seen like this, maybe, but he also doesn’t want to stop. Shame and need run tangled under his skin, twisting tighter with every stroke.

Castiel leans in close, breath ghosting over Dean’s neck before he presses his lips to the skin. He kisses soft at first, then opens his mouth and bites down at the tendon with just enough force to make Dean whimper, jerking beneath him.

“You take it so well, Dean,” Castiel murmurs against his skin, voice thick and affectionate. “You’re beautiful like this. I want to see all of you.”

Dean makes a choked sound, the only reply he can manage. He’s too far gone to speak, his hips stuttering into Castiel's fist like his body is chasing the rhythm on its own. Every muscle in him is tight, vibrating, strung out on a thread of frustration and longing. He needs more. He’s burning alive and Castiel knows it.

Castiel drags his mouth lower, kisses down Dean’s stomach, then bites at the edge of the stamp still vivid on his thigh. His tongue traces the ink, slow and wet and completely unnecessary, and Dean gasps, whole body flinching like he’s been shocked.

“Tell me what you want,” Castiel says, voice all grit and command, as if he doesn’t already know. “Use your mouth, Dean.”

Dean groans, head tipping back, the muscles in his neck strained and tight. “Not enough,” he whines, words trembling with frustration. His eyes squeeze shut and Castiel sees the shine of unshed tears gathering at the corners, delicate and humiliating.

It’s a gorgeous sight, honestly. Someone like Dean, cocky and loud and sharp-tongued, begging like this, raw and wrecked and desperate. Castiel takes a second to admire it.

“Fuck,” Dean sobs out, voice cracking. “Please, fuck me.”

Cas’ hand slows even more, almost to a crawl. It’s so close to stopping entirely that it might as well be. He lets a long breath drag out of him, basking in the tension like a cat in a sunbeam. He considers himself a pretty decent guy in most situations, he wants to fuck Dean, he really does. His own dick is aching if he pays any mind to it, but this? This he wants to savor.

“What I’m doing isn’t good enough?” he asks, tone low and teasing, soaked in mock innocence. “You’re saying you don’t want this? My hand’s not enough for you?”

Dean’s hand scrambles blindly, finds Castiel's wrist and clings like a lifeline. His voice is wrecked, raw and high with desperation. “Please, Cas, I want—I just want to come, please. I need you to make me good, I’ll do anything, just—just don’t stop.”

“Okay, okay,” Castiel says, giving in without much resistance, like he’s had mercy waiting just behind his teeth the whole time. His hands move quickly now, shoving Dean’s boxers all the way down, baring him completely.

He wraps his hand around him again, this time with no hesitation, no pretense. His grip is firmer, strokes longer and faster, his thumb dragging across the head with slick, practiced pressure that makes Dean cry out, hips bucking helplessly into it.

“You are good,” Castiel says, his voice softer now. His gaze is locked on Dean’s face, watching the way it twists with every thrust of his fist. “You’re so good for me, Dean. Let go. I want to see you fall apart.”

It doesn’t take much more. Dean’s already been trembling on the edge for what feels like hours, body loose and taut all at once, nerves frayed down to nothing. His mouth falls open around a broken, helpless whine as his legs fall wider, thighs quivering.

When he comes, it’s all heat and white noise, shuddering so hard the desk creaks beneath him. His release spills hot over Castiel's hand and across his own stomach, messy and overwhelming.

For a moment, neither of them speaks. There’s only the sound of Dean’s breath catching in his throat, the wet slide of Castiel's palm still stroking him through the aftershocks, and the quiet weight of approval in Castiel's eyes.

The stamp still burns red above the mess, a mark of patience and power and the fact that Dean had begged so beautifully for it.

Dean drags Castiel down by the front of his shirt, the buttons straining under his grip, and buries his face in the curve of Castiel's neck. He’s trembling all over, skin flushed, sweat-slicked and clinging, heart thudding against Castiel's chest like it’s trying to punch its way out.

The aftermath settles between them, heavy and warm. There’s a stickiness to the air, a quiet hum of something intimate and spent, but nowhere near finished. Castiel stays pressed close, his forehead resting against Dean’s temple, breathing in the heat radiating off of him. He can feel Dean’s thighs still trembling around his hips, can feel the unsteady rhythm of his breaths, the faint dampness on his cheek where tears had dried. Dean's body is limp, boneless, used up, but his cock is already twitching back to life against his stomach, half-hard and eager.

It’s always like this. Dean gives everything and then looks up at him like he’s still waiting for more. Like Castiel has something in him worth aching for. His eyes are wide and glassy, never leaving Castiel's face, hungry and hopeful all at once.

Sometimes, Dean bites at Castiel just to get something back, something animal and claiming, but tonight he hasn’t. He promised not to, and for once, he’s actually kept his word. His mouth, which would usually be pressed hot to Castiel's neck or collarbone by now, has stayed in place, resting against the soft curve of Castiel's shoulder like a truce.

Castiel pulls back slightly, just far enough to get a look at him. Dean’s thighs are spread and trembling, the stamp Castiel had pressed into his skin earlier still glowing red on the soft flesh, just above his knee. There are faint smudges around it, where Cas had touched and kissed and bitten. His thumb drags over it briefly, before reaching for the little plastic circle beside them.

He clicks out another stamp, the design barely visible before it meets Dean’s skin. This time, he places it higher, tucked right into the tender crease where thigh meets hip. It lands with a soft click, leaving behind another bright red mark, sharp and fresh.

“Another one,” Castiel murmurs, thumb brushing over the new stamp. “For being so good for me.”

Dean’s breath catches in his throat. His eyes flutter closed for a second, lashes trembling before he lets out a shaky, soft “Cas—” like the word itself is too full to finish. It isn’t a question, or even a plea. Just stunned gratitude, quiet and messy and impossibly sincere.

Castiel leans down again, mouth finding the mark, kissing it before his teeth sink in right beside it. Dean yelps, high in his throat, the sound swallowed into a gasp as Castiel sucks a bruise deep and dark beneath the ink. His legs jerk on either side of Castiel's shoulders, toes curling, and Castiel soothes the bite with a warm, wet tongue, mean and gentle in equal measure.

Dean is panting now, hips twitching, cock throbbing between them. His voice is thin and hoarse, but it doesn’t waver. “Please,” he breathes. “More. I want you in me, I need it, please.”

It’s the kind of want that sounds like desperation, but Castiel knows better. Dean wants it the way he always wants it, like it’s the only thing in the universe that could ever make him feel whole. The way he says it, low and aching, makes Castiel feel like a god.

When Castiel lifts his head, the whole world feels out of focus. Dean is the only clear thing in the room, blown pupils, flushed cheeks, his lip between his teeth, his hands twitching like he doesn’t know what to do with them.

Castiel doesn’t think. He leans in and kisses him, deep and hard, mouths crashing together with no finesse, no care. Dean whines into it, desperate, greedy, kissing back like he’ll crawl inside Castiel's lungs if he’s allowed. His hands fist into Castiel's shirt, yanking him closer, clinging like he’s drowning and Castiel is the last breath he’ll ever get.

Castiel's hands roam fast, pushing Dean’s shirt up to his ribs, baring his heaving chest, fingers dragging across bruised, sensitive skin. He palms one of Dean’s nipples, tweaks hard enough to make Dean jump and whimper. There’s no patience left in him, just raw hunger. And despite everything, Dean is somehow full hard again, cock flushed red and already leaking, thighs flexing like he’s trying to keep himself still but failing miserably.

It’s almost laughable. Castiel lets out a quiet, breathy huff, more amused than anything. “You’re already hard again? What the hell are you made of?”

Dean just nods, eyes hazy and unfocused, too far gone to form anything close to a clever reply. His hips lift faintly, chasing Castiel's touch without shame.

Castiel pulls back enough to take him in properly, then shoves a hand through his own hair to collect himself. His chest rises and falls hard, like he’s run ten miles, but he still manages to keep his voice low and firm. “Don’t move,” he says. “Stay exactly where you are. Hands on your thighs. If you’re patient, you’ll get another.”

Dean nods so fast it’s pathetic. He swallows hard, mouth open, chest heaving. His hands drop to his thighs obediently, fingers spreading wide like he knows exactly what Castiel wants to see. He looks wrecked. Beautiful. Shirt bunched around his ribs, cock leaking onto his belly, skin flushed pink with arousal and scattered marks, each one of them a quiet proclamation of Cas’ hands, his teeth, his stamps, himself.

Dean glances up at him, barely holding himself together, and the look in his eyes is clear as day.

He’ll wait. But only just.

Castiel finally stands, stretching out the tension pulling at his lower back. His legs feel tight, hips sore from holding still too long, and his cock is still achingly hard, pressed against the inside of his pants like a cruel joke. The pressure is maddening, fabric clinging to damp skin, but he savors the ache. He likes the reminder of want, the heaviness of it sitting hot and solid in his gut, the sharp pulse of not having yet.

He walks toward the nightstand with purpose, ignoring the wet sound of Dean’s breath hitching behind him. Even from across the room, he can hear it, those broken little inhales, the faintest scrape of Dean’s heel tapping the table’s edge like he’s trying not to squirm. Trying and failing.

The drawer opens with a soft click. Castiel keeps it organized, of course, but fumbling through it now feels like an eternity. His hands feel too big, too clumsy. He finds the lube, and then the box of condoms, tucked beneath the edge of a folded towel. When he turns around, arms full, Dean is still exactly where he left him.

Hands flat on his thighs. Chest rising in deep, uneven pulls. Mouth parted and glossy, lips wet from being chewed on. He looks like a painting in motion, one trembling with need.

Castiel drops everything onto the table. He leans down again, this time slower, deliberately. The tip of his nose brushes Dean’s cheek before he murmurs against his skin, “Such a good boy.”

Dean’s breath stutters. He doesn't speak, not yet. Just whines, helpless and wrecked, when Castiel reaches for another stamp and presses it onto the opposite thigh. The ink blooms bright and dark across flushed skin, a fifth red mark among a growing constellation of approval.

Dean finally breaks. “Please,” he gasps, his voice raw and fraying. “I want you—”

“I know, Dean,” Castiel whispers, kissing the newest stamp, his voice warm and low. “I know. I want you too. Want to mark you up even more. Want to fuck you full of it, so anyone who sees you knows you're mine.”

He lets his teeth drag slowly along the inside of Dean’s thigh, just beside the stamp, sinking in until a bruise blossoms there too, deep and dark. Dean cries out, his body jerking forward like a live wire, hips lifting off the table in silent invitation.

“Please,” Dean gasps again. His eyes are wide and frantic now, pupils blown. “Please fuck me, I need it. I need you to make me good again.”

The air shifts around them, thick with heat and the kind of hunger that borders on unbearable. Cas slicks his fingers fast, not bothering with teasing, and then pushes two inside at once, knowing full well Dean is still oversensitive, still raw and trembling from the last orgasm.

Dean arches with a sharp cry, head tipping back, tears wetting his temples. His thighs twitch violently, trying to spread wider even as they tremble. His whole body shakes as Castiel curls his fingers, thrusting deep and scissoring them slowly, letting the stretch sting just enough to make Dean sob.

“You’re doing so well,” Castiel murmurs, leaning in to press a kiss just above Dean’s belly button. “Taking it so well for me. Look at you. Such a good boy, letting me see you like this.”

Dean's voice cracks when he speaks again. “Please, Cas—please, I need you, need it, need you in me, please—”

That’s all it takes. Castiel pulls his fingers free with a wet sound, wiping them on his shirt without care. Normally, he’d go slower, take his time, but tonight there’s no space left for patience. His hands shake slightly as he rips open the condom packet, rolls it on over his aching cock, and fumbles his pants open with too-fast fingers. His underwear is soaked at the front, clinging to him, and he pushes both down just far enough to free himself.

He slicks his cock thoroughly, the lube cold at first before it turns warm from the heat of his skin. Then he crawls back between Dean’s thighs, hands firm on his knees, spreading him wider. He takes a second, just one, to look.

Dean is flushed everywhere, lips bitten red, chest blotchy, cock hard and leaking onto his stomach. His thighs are a mess of ink and bruises, marks Castiel left there like signatures. His eyes are glassy and wet, shining with trust and want, and it’s all for Castiel. Every inch of him.

Castiel lines himself up and pushes in slow, eyes locked on Dean’s face, watching every flicker of tension and every twitch of his mouth as the stretch starts to bloom.

Dean moans like it’s a confession. Like Castiel is dragging a truth out of him, thick and burning, one inch at a time. His body fights it for a moment, too tight from the way Castiel rushed him, but he doesn’t tell him to stop. He clings to the edge of the table, jaw slack, eyes fluttering, and takes it.

All of it.

“So good,” Castiel whispers, voice rough against Dean’s jaw as he sinks deeper, his cock stretching him open inch by inch. “Taking me so well, letting me mark you up. Look at you, Dean. You’re perfect like this.”

Dean sobs, his mouth slack, eyes glazed and unfocused. His hands grip Castiel's wrists like lifelines, fingers digging into the tendons as Castiel rocks into him. Every thrust drags over something deep and raw, pleasure blooming bright and unbearable through him. The sharp sting of bruises, the wet press of ink against his thighs, the way Castiel fills him so deep it feels like he’s carved into him. It all blurs together. Praise. Pain. Pleasure. Dean can’t tell where one ends and the other begins.

“Is this what you wanted?” Castiel grits out. His hips snap forward, the sound obscene, skin meeting skin again and again, each thrust just this side of brutal. Just shy of too much. “This what you needed?”

Dean’s body jerks, trembling underneath him, so hot and tight around him it borders on painful. He’s already spent, twitching and sore, but he doesn’t want it to stop. He never wants it to stop. Not when Castiel is looking at him like that. Not when he’s inside him like that.

“Yes—fuck, yes, please, don’t stop, don’t—” Dean sobs, voice breaking as his head tips back hard against the table. His hands scrabble for purchase, muscles straining, back arching. “Cas, please, please—”

Castiel fucks him through the overstimulation, steady and relentless, the rhythm brutal but intimate. Every thrust drives him deeper, deeper into Dean’s spine, into his bones, into everything he is. His voice stays soft, a steady stream of filth and praise poured against Dean’s skin, each word a blessing and a command.

“You’re doing so well for me. Letting me fuck you open, letting me ruin you. My good boy. My perfect boy.”

Dean cries out, legs shaking uncontrollably, heels digging into the edge of the table. Every time he moans, Castiel bends lower, his mouth finding a new place to bruise. His lips drag over sweat-slicked skin, hot and wet, then bite down on Dean’s ribs, his chest, the inside of his thigh. Everywhere. His fingers follow, pressing another stamp into soft, tender flesh, ink smearing faintly where sweat and heat melt it into the shape of Castiel's praises.

When Dean comes again, it’s sharp and shattering. His whole body locks up, every muscle drawn tight like a live wire. It’s not graceful. It’s not quiet. He sobs through it, voice broken, body trembling violently as he spills across his stomach and Castiel's chest without ever being touched. The orgasm rips through him, raw and ragged, a full-body surrender.

Castiel doesn’t stop. He slows, but he doesn’t stop.

He fucks him through the aftershocks, each careful thrust coaxing every last tremor out of him. His voice gentles further, breaking into murmurs. “Good boy. So good for me. All mine. Mine.”

Dean whimpers at the words, legs trembling where they’re hooked around Castiel's hips. His throat works like he wants to speak, but only more broken sounds come out. Nonsense and yes and Cas.

Castiel groans low in his throat, rhythm starting to falter. He’s close, hips jerking forward less steadily now. “Gonna fill you up. Gonna come so deep inside you. Gonna ruin you for anyone else.”

Dean’s eyes flutter open just enough to meet his gaze. Wet. Glazed. Worshipful.

That’s all it takes.

Castiel pushes in hard and deep, holding himself there as he comes, the sound caught in a half-sob in his throat. His whole body tenses over Dean’s, cock pulsing, his hips twitching with each wave of release. He buries his face in Dean’s neck, groaning helplessly as his body shakes with it.

The world narrows to the heat between them, to the wet stretch of Dean’s body around him, the slick mess on their skin, the ache of overstimulation, and the evidence of Castiel's ownership inked and bitten into Dean’s thighs.

Castiel finally pulls out with a low groan, condom wet and heavy as he disposes of it blindly. Dean flinches when it leaves him, whole body twitching with aftershocks. But Castiel doesn’t give him room to drift yet.

He slides down Dean’s body, mouth dragging a slow, reverent trail across his stomach, over the marks he’s already left. His tongue laps gently at the come spilled across his abs before dipping lower, licking sweat and salt from the crease of Dean’s thigh. Dean jerks when Castiel's teeth scrape over the sensitive skin there, a low sob breaking from his throat.

Every time Dean trembles or gasps, Castiel stamps a new spot, fingers sticky with ink, pressing symbols of praises and ownership into any skin he can reach. His mouth follows each one, lips tender, then teeth cruel, dragging more bruises from pale, already trembling flesh. The inside of Dean’s thigh is mottled now, a mess of red ink and swollen love bites.

Eventually, it becomes too much.

Dean’s hands reach down weakly, pushing at Castiel's shoulder, fingers trembling. “Cas, can’t—too much,” he breathes, voice frayed, body twitching from the edge of exhaustion.

Castiel relents instantly, pressing a soft kiss to the curve of Dean’s knee, just beside the last bright mark. His mouth lingers there, not to tease, but just to breathe against him.

“I know, Dean,” he murmurs, voice wrecked but gentle. “I’ve got you. No more. You did so good.”

Dean’s only answer is a long, shaky exhale, his hand curling loosely into Castiel's hair, grounding himself in the only thing left real.

Castiel stays there, between his thighs, quiet and warm. Watching the marks fade. Watching Dean breathe. Watching the way the ink and bruises tell the story of how much he was wanted. How much he gave. How much Castiel took, and loved.

It’s late Monday morning, and the classroom smells like dry-erase markers, burnt coffee, and the last traces of weekend apathy. Castiel is at the front, erasing a particularly chaotic diagram on the board, sleeves rolled up and glasses sliding low on his nose. 

Dean, who isn’t even enrolled in this class, is slouched at a desk in the front row like he belongs there. He’s got one leg up on the seat next to him, a mechanical pencil dangling between his fingers, and the world’s most irritatingly smug look on his face.

The room is mostly empty, the few early students too absorbed in their phones or last-minute homework to pay attention. Dean waits until someone turns on music through their earbuds before leaning forward, voice low.

“So, uh.” He pauses, just enough to make Castiel look over his shoulder. “When do I get the gold stamp?”

Castiel blinks at him once, then turns back to the board. “Gold?” he asks, too casually. “That’s a rare honor.”

Dean grins. “Thought I earned it last night. Or, you know. Early this morning. Somewhere around the second orgasm, maybe?”

Castiel doesn’t look at him, but the corner of his mouth twitches, just barely. “Mm. Not quite.”

Dean frowns, mock-offended. “You stamped me like ten times.”

“That was red. Red means you’ve met expectations,” Castiel says calmly, underlining a word on the board. “Gold is for exceeding them.”

Dean lets out a low whistle, leaning back in his seat again. “Cold. Brutal. Kinda hot.”

Castiel glances at him then, finally, eyes gleaming behind his glasses. “Earn it first.”

Dean’s breath catches in his throat at the way it’s said, soft, quiet, laced with promise. A challenge.

The bell rings, loud and jarring. Castiel turns back to his notes like nothing happened. Dean shifts in his seat, suddenly feeling very awake.

Yeah. He’s definitely staying after class.
