Across the room, you give Rin a look.  

One that he’s starting to recognize without trying to. It makes his jaw clench when he sees it. Big, wet eyes like a baby deer and the soft undertone of desperation. He’s becoming good at knowing your ticks, mostly against his will. How you chew your lip, how you tap the pen of your tablet, how you draw in a frenzied anxious way when you want something from him and don’t know how to open your mouth and ask.  

It’s irritating. But it’s going to get under his skin even more if you keep it up. 

“What.” He grits. You startle. Jump in your skin like you’re surprised he even noticed you, as if you’re not staring at him. You open your mouth, then close it. “Spit it out.”  

You look flustered. You always look that way. But right now you embody it. He can’t imagine what your request could be at this point that would incite this much embarrassment.  

By now, Rin has “helped” you with a number of things. Too many to recount and all of them too close, too personal for plausible deniability. Helping you take photos for references takes up a majority of your requests - but it always ends in something more. Rin tries mostly not to think about it. Not to think about where its led and how normal you still seem to act despite it.

The fact you keep making these requests reason enough to make him seethe. Just a little.  

You take a shaky breath and give Rin a look from above the frames of your glasses.  

“C-can I give you a hickey?” 

Rin pauses. Opens his mouth before he can even think about what the appropriate reply might be. His words come out like a hiss.  

“Why?”  

You seem surprised that he asks. That he cares to. That alone feels reason enough for him to shake some sense to you. Grab you by the shoulders until it clicks.  

(He doesn’t interrogate what it is that he wants to click for you. Just that he wishes it fucking would already.)  

“Well. Uhm.”  Your feet rub together under your desk. Woolen socks worn until they’re matter as you fidget endlessly. Rin holds his stare until you crumple just slightly under the weight of it. “There’s n-not a particular reason. It’s not for my book or anything, I just uhm—wanted to do it. To you,”  

There’s a brief moment there where the world stops spinning entirely. Rin breathes. A sharp, steadying breath. Chest tight, dizzy with an emotion that wells up from the depths of him. He can’t think of anything clever to retort with, or really any good way for him to respond. He sits across from you at a complete loss.  

The next words that come out of his mouth leave before he has a chance to make sense of them. He swallows a lump in his throat.  

“Fine,”  

Your eyes go wide again. Shocked like you weren’t the one who ask. Tension lingers in the air, but Rin can’t figure out what to do about it. How to settle it. He doesn't know if he fucking can.

“A-are you sure?”  

That’s the first time you’ve asked him that. Most of the time, you’re shameless in your asks. You do it for work, just work  - and it’s always Rin who ends up….going further. Because it frustrates him to see you cower over it. Rin is used to you, by now. How you have the demeanor and general anxiety of a small shelter dog. He’s been over it all already one hundred times but—

It’s like something clicks hearing you ask him that. If he's sure. You can be so thick. It’s not like Rin doesn’t fucking know. But it’s the first time it he realizes the brunt of it.

You two are on completely different pages about your relationship.  And he's pissed about it, but not at you. Not really.

“I wouldn’t say it was if it wasn’t,” 

You look so surprised for a minute he wants to bite you. Take his teeth and dig them into the place your pulse is just to see you squirm. It’s always like this with you but right now it feels like something searing. Pressed up right against his ribs and threatening to puncture his lungs.

“Are you gonna do it or not?” He snaps, meaner than he wants. You nod, movements stiff, and clamber onto your feet before walking his way. Rin watches as you approach him nervously. Your eyes meet and you hold his gaze.  

Then, without word, you crawl into his lap. Straddling him - just barely fitting over his wide frame as both of your knees end up on either side of his thigh. Rin watches you silently. Piercingly. Your movements are trembling.  

You kiss him first. This shocks him into total silence. He returns it just so you don’t pass out from nerves. It’s clumsy like he knew it would be but it’s the first time you’ve done completely of your own accord. Normally you ask him to kiss you, beg with teary eyes.  

But you’ve got both of them squeezed shut now, kissing him with your hands fisted at his chest. Something stirs in his jeans, and you yelp when it presses against you. You gasp, low and quiet.  

“You’re—“ 

“Shut up.”  

You nod. Keep kissing him, opening his mouth up to slide your tongue in. It’s sloppy and unpracticed. You have no grace whatsoever.

Rin feels himself get so hard he’s lightheaded.  

You pull away, gently kissing the corner of his mouth. Down the line of his jaw. Mimicking something he’s sure you’ve read in your stupid doujins at one time or another. He can feel the nerves radiating off of you in waves, feel the way your body shakes in his lap. How uncertain you are. There’s that feeling again. Gnashing, possessive, mean. Not that Rin has ever been someone especially saintly.

But it’s not cruelty he wants to expose you to. It’s something else, far more demanding.  

His hands find your hips in a single breath. Pushing you down onto his lap until your full weight is rested over his hard-on. You whine when he presses up against your core, clothed cunt protected through ratty PJs. Rin doesn’t say anything, buy you know better than to stop now.  

Kissing down slowly, sweetly - you scrape and lick along his skin until you’re just underneath where his jaw and neck meet. Your eyes flutter open to look at him. It's too much for him.

Rin grinds his hips up in retaliation until you whimper. He does it over and over, steadily until you’re both rocking against each other in tandem. All clothes and hot heaving breaths, layers of fabric acting as barrier for what he's after.  

You’ve done everything under the sun aside from sex. This barely counts as foreplay by now. Even so, he’s bucking up into you with every ounce of his strength, unspoken desire shredding his sense. His hands gripping your hips, jaw grit - pleasure coiling in his stomach and wound so tight.  

“Fuck,”  

You’re crying out against his shoulder before you remember what you were trying to do.  

Your lips find his neck again trying not to be too noisy. Latching on with a soft kiss, Rin hisses as your teeth finally sink into the flesh. Your mouth is small. It’s all he can think about. He feels your incisors scrape against the skin, tongue tracing a vein. Before long, you’re sucking hard on the same spot. He can feel it. A bruise forming, broken capillaries blooming in deep dark hues of purple and red. Rin groans at the feeling. You give it every ounce of effort, holding onto his bicep tight when you do. It aches in a pleasant way.  

Pleasant enough to make his hips buck. A jolt of desire and want rips through him like a shockwave - until he’s pushing you down against the hard outline of his cock and forcing you to grind against it. It’s hard and sharp, fingers bruising. 

He cums hard. Seconds later, like a flash of lighting. His stomach flips and something rips through him and—

It’s the first time he’s cum before you. Fuck, h can feel his own cum seeping through his boxers and jeans. It’s so intense his vision blacks out for a minute before returning to him, chest heaving as you pull away and stare.  

“You—“  

Horror washes over him. Rin puts a hand over your mouth, angry and irritated. Red up to his ears to his ears and internally having the worst crisis of his life for the third time over.

He looks at your face and there's that feeling in his chest. But he recognizes it this time. Knows exactly whats making him like this, forced to confront it for the first time.

“Shut up,” He hisses, breathing heavily. “Not a fucking word,”  

You nod at him docile. Rin forces himself steady as he thinks of pinning you down and taking you.

Like he knows you'd let him. Like he fucking knows he wants to.
