College Sheith AU where during a stressful midterm week Keith goes scrolling for a hook up on grindr and comes across a God with abs, no headshot and a very strict set of rules for hooking up with him.
2
The rules are simple enough:
1. No names
2. No repeats
3. No marks
4. No exceptions
Keith's not so good at following rules, but the five golden stars under the dudes username are tempting.

He shoots the guy a simple 'hey', chin in hand as the professor drones.
Five minutes later a short 'Did you read the rules'
Keith sits up a little straighter, 'Yeah. No problem.'
An address for a hotel near campus and a room number comes next.

Keith shows up at the designated time with zero homework to do and the resignation that if he gets murdered, at least he won't have to take any more tests.
He knocks four times, nerves tangled in his belly.

The locks slides free and chills creep up the back of Keith's neck as the door opens revealing-
'Shiro?'
The TA for his physics class.
The one he has a mid term for at 7 am.
The one Keith's been crushing on all semester.

Shiro looks shocked for a second before giving a teasing, 'Don't you have a test tomorrow?'
'Are you even allowed to fuck students?' Keith blurts.
Shiro laughs, leaning into the door with his forearm. His bicep stretches the shirt he's wearing.
Keith hopes to god he says yes.

Shiro's smile eases into something familiar and welcome, 'Needing to ease a little stress?'
Keith swallows, 'Maybe.'
But Shiro's rules are absolute, even in class. Keith's pretty sure 'I won't sleep with students' is an unspoken one.

Keith's expecting a polite, very Shiroish let down.
He doesn't expect Shiro to reach out and hook a metal finger through his belt loop with a soft, 'Let's see what we can do about that.' Before dragging him into the room.

Keith follows like melted plastic. He folds into Shiro's chest as the door clicks shut and a massive arm hovers over his shoulder to slide the bolt into place.
Shiro holds his gaze the entire time.
Keith practically sizzles on the spot.

10
The hand hooked on Keith's pants pushes his shirt up, metal knuckles cool against his belly, 'Any requests? Preferences?' Shiro leans forward, lips brushing from temple to ear, 'Fantasies?'
Keith's hands curl into fists on Shiro's ridiculously tight shirt as his skin tingles.

11
There are so many Keith doesn't even know where to start. There are definitely too many to do in one evening.
He'll have to prioritize. He only gets this once.

12
Keith unclenchs a hand and glides it down Shiro's chest, stopping just shy of his waistband.
He lifts gaze to meet Shiro's.
Then lowers himself to his knees, fingers making quick work if button and zipper.

13
Shiro's inhale is audible, the bulge behind the grey boxers unmistakable, the tighting of his abdomen castinf shadows on skin.
Keith's mouth waters as he curls a hand over the long, thick outline of him.

Shiro presses both hands to the walls on either side of the tiny foyer.
Keith watches those big arms tense, grey eyes gone completely black as they watch Keith pull his cock free through the slit.

15
Keith strokes the thick length of him a few times, loving how much it's leaking, ready to have it down his throat.
He can almost taste it.
So, he does.
He can almost taste it.
So, he does.
16
He starts out with a broad lick through the precum gathering at the head. Fingers tight around the base, other hand holding Shiro's shirt out of the way.
Shiro's thighs tense, but he doesn't make a sound.
Keith hums, enjoying the weight and the scent.

17
He thumbs over the slit, insides purring at the new slick oozing and his own arousal leaking between his legs.
He makes a show of licking it off his thumb, eyes locked with Shiro's.
He gets a twitch of a jawline, a tremble in his arms.
Keith smirks and goes in for the kill.

18
Shiro lets out a ragged, broken sound as Keith swallows him down.
It floods Keith's belly with renewed heat.
He moans around it, eyes fluttering closed, throat stuffed full.
'Oh god - k - keith -.' A gasp as Keith sucks, 'Fu - oh go -.'

19
It's music to Keith's ears.
He fights back the urge to whine at how good Shiro feels in his mouth.
It's no easy task.
The more he moves, the more noises Shiro produces and the heat between his legs worsens.

20
He's about to say 'fuck it' and jerk off right there onto the ugly hotel carpet, but then Shiro's hands are in his hair.
And he's being pulled into a kiss that makes his whole body light up.
'Your mouth-.' Shiro sucks at his bottom lip, 'Should come with a warning.'

21
Keith doesn't even have time to laugh and say 'you could always ask my teachers'.
Shiro pulls him to the bed, stripping them of their clothes with little to no separation of the frantic kiss that is slowly turning Keith's brain to mush.

22
'Ride me.' Shiro gasps against his lips, hand wrapping around Keith's cock before they hit the bed in a tumble of limbs.
'Okay.' Keith agrees, watching as Shiro digs around in a duffle bag at the end of the bed for supplies.

23
Shiro drags him astride his hips, both of their cocks slotting together.
Keith inhales, biting into his lip as Shiro wraps them both in one hand.
He digs his nails into Shiro's thigh, hips jerking and body throbbing.

24
Shiro fumbles with the lube in one hand, eyes watching the wet, slippery slide between his fingers.
Keith takes pity and plucks it from his hand, 'I prepped before I left.' He oozes a little on his fingers and does a quick swipe and stretch, 'Kinda hoped you'd have a big dick.'

25
Shiro watches him with a hunger that burns in the best way, 'As big as you hoped?'
'Bigger.' Keith smirks, rips open the condom and makes a show of putting it on with his mouth.
Shiro whimpers.

26
'Ready?' Keith asks, lifting to his knees and holding Shiro's dick just shy of his hole.
'S-shouldn't I be asking you that?' Shiro's hands curl over his thighs, thumbs digging into the soft, untouched skin there.
Keith shrugs and lowers himself down.

27
He talks a good game in his head. About how he's going to be cool and cocky about taking Shiro in one fell swoop.
Instead, he lets out a throaty whine, knees curling in as he feels the stretch all the way to his throat.

28
Shiro's hands push his thighs apart with a growled, 'Show me.'
Keith trembles and obeys.
He lifts up, till just the head lingers, then slams back down.
'Yes.' Shiro hisses, swiveling his hips up to meet Keith's downstroke.

29
Keith moves without thinking. He rises and falls, knees digging into the mattress, hands pulling at his hair and nails scraping down his neck.
Everything is on fire. He can't breathe properly. His cock slaps against Shiro's belly.
'Look at you.' Shiro croaks, 'Beautiful.'

30
Keith's never been called beautiful before.
He bites his lip so hard it hurts.
He can feel every inch of Shiro's cock. Can hear the growled praise, peppered with his name, the wet slap of flesh.

He doesn't last long.
His vision blurs and the orgasm hits him in the back of the head
He slaps his hands against Shiro's chest, nails digging into the skin as he cries out Shiro's name.

32
He cums like that. Cock sputtering onto Shiro's belly.
Grinding against the cock inside him and twitching with every rushing wave of heat.
'Fuck.' Keith pants, arms shaking.
He can see the red on Shiro's chest even through the blur of tears.

33
He left a mark.
He left ten marks.
Ten glaring, red marks in half moon patterns like constellations on his skin.
'Fuck - sorry - I-.'

34
The world tilts violently and Keith is on his back staring up at Shiro's face.
He's big above him.
Sweat at his temple, still throbbing inside Keith's ass.
'Hold on, baby.'

35
Keith frowns, 'Hold on to wha-.'
Shiro bends one of his legs over his shoulder and slams inside.
Keith shouts, back arching off the bed, hands slapping around Shiro's biceps.s

36
Shiro's hips sling in and out, gaze holding Keith's steady, jaw tight and chest flushed a bright, brilliant red.
Keith babbles out unintelligible sounds. Eyes unseeing. Cock barely even hard.
Nails digging new wounds in a very visible place.

37
'That's it.' Shiro gasps, 'Come again for me, baby. Come on.'
Keith can't. He says so. He thinks.
Or maybe he just sobs it.
Keith can't. He says so. He thinks.
Or maybe he just sobs it.
38
Either way, he cums again. Painful and too hot for the skin he inhabits.
And for a few short seconds, he's pretty sure he's a pilot flying a sentient mechanical lion

39
'Good boy.' Shiro hisses, dragging his hand through the mess on Keith's belly and bringing cum smeared fingers to Keith's lip.
He opens without question. Too tired to resist. Whole heartedly ready to do anything Shiro asks.

40
Shiro groans, painful and beautiful and cums with a harsh exhale of Keith name from his mouth.
He digs his groin against Keith's ass, teeth sinking into the soft tendon of Keith inner knee.
He sucks and growls and presses a kiss as an apology.

41
The only sound in the room is harsh breaths and the rush of blood and heart beat in his own ears.
Keith stares at the ceiling, whole body trembling.
Shocked.
Ruined.
In love.

'You okay?' Shiro eases his leg down, hands massaging the muscle of his thigh.
'Yeah.' Keith's voice comes out in a hoarse whisper.
'Let's wash up and get you some water.'
'Yeah.' Keith's voice comes out in a hoarse whisper.
'Let's wash up and get you some water.'
43
Shiro slides out, gentle and slow.
Keith feels a piece of him go with it.
He lets Shiro wipe him down, help him to the shower.

44
It's strangely intimate.
Shiro washes his hair, presses kisses to his lips while his head is tipped back.
Saying good bye at the door seems like a tragedy.
But he gives Shiro a smile. Gets one in return.
Thinks he's imagining that Shiro's looks as sad as his feels.

45
He takes his physics midterm with a sore, but satisfied ass.
Shiro is the one who gathers up their sheets and it doesn't hurt at all when he doesn't give Keith any more attention than he gives the other students.
It doesn't.

46
Keith shoulders his backpack when the class ends, debating on crawling into his dorm bed and sleeping till December.
'Did you see the marks on Takashi's arms?'
Keith pauses at the voices behind him.

47
Curtis and Veronica sit behind him.
They're known to gossip.
Keith should leave.
'Someone broke a rule.' Veronica snickers.
'Lucky.' Curtis grumbles, 'He turned me away when I found out it was him.'
'Wow. Really?'
'Said he didn't want to sleep with students in the class.'

48
Keith stares down at his desk top. Heart in his throat.
'Boring.' Veronica huffs.
'I tried again last night, but his profile was gone. Guess he had his fill of the campus.'
Their chairs scrape, 'Or his rep was getting around.'

49
Keith waits until their voices fade before he stands up and leaves the classroom.
Shiro and the professor are talking at the desk as he passes.
Keith almost doesn't look.
But he does.
Shiro's eyes meet his as they pass.
He smiles and mouthes 'Wait for me?'

And they date all through college and get an apartment together and a big fluffy dog
And they live happily ever after
The end!
