Rin Itoshi has a bad mouth. Sure, his vocabulary is not too full of curse words, but by god he insults people way too much. Whats crazy about it, is he actually believes what he says, and often times you have to cover his mouth before he accidentally picks a fight with someone. He is cool and collected 90% of the time, and because of his aloof attitude, it drives people insane when they hear his rude, blunt words.
You are working on it with him, or at least trying to. Whenever he is rude to someone, you quickly scramble to apologize and reassure that he meant nothing harmful. By the end of it, he always gives you the strangest stares, wondering why you care enough to explain himself to the other person. But you were kind, and he…had other good qualities about him.
He discovered something new about himself during this time as well. You were sitting on his lap, talking to some guests at the two of yours apartment, when one of the guys teased Rin’s cold personality just a tad. Before your lovely boyfriend could bark back a probably way too passive aggressive reply, you covered his mouth with your hand, accidentally slipping one of your fingers into his mouth.
He stared at you in silence while the others gently laughed, and moved away from the conversation. He teasingly licked at the digit, and your smile widened to hide back a shiver, pretending nothing is amiss to the others. You pulled your hand away a couple seconds later, and he unconsciously followed it, blinking at you when you stared at him in confusion.
And ever since that day, Rin found himself feeling…strange. It didn't affect his day to day life, but he realized that having stuff in his mouth, made him feel strangely calm. After a quick google search, he realized he must have an oral fixation that he has not discovered until now.
He took to lollipops for a week, justifying himself to you by blaming it on his sweetooth (that he doesn't have). Once you teased him about ruining his teeth from all the sugar, and he stopped. He bit his nails for two days, and even if it did help him focus on the task at hand, it made him feel unsanitary and gross. He considered trying smoking, but his career depended on his lungs, so he threw that thought away.
Toothpicks and gum are his savior currently. With either of the two in his mouth, he finds himself less uptight, and it calmed his day to day nerves. It made him feel better all and all, and it didn't hurt him, so he was fine with his fixation.
But, ever since that day where he felt your finger in his mouth, he has been daydreaming about it. Two, or three of your digits would make his mouth completely occupied, and with them, he probably wouldn't be lost in his thoughts. It was just a passing thought in the beginning, thinking that maybe he nonchalantly ask you to put your (clean, he would specify) fingers into his mouth, but recently, the thoughts have gotten more lewd.
What would it be like to have your fingers forcefully roam his mouth while he blinks back tears from the roughness? What would it be like for you to gag him when you reach too far in his throat? Would you laugh at the noise, or would you coo at him? What would it be like for you to spit in his mouth? After that thought, he decided to never talk to you about it. He had a pride to withhold.
But you quickly noticed your boyfriends new found stress reducer. He didn't necessarily hide it, but when you ask about it, he always deflects the conversation and then gets cranky when you don't let it go. You know Rin’s ridiculous behavior by heart now, so you know he is hiding something.
So, on the one day off he has from practice, you decided to confront him on whatever the hell was going on. With gifts.
“What the fuck is this?”
You cringe, and let out a breath. You definitely shouldn't have bought that. “Uh…A pacifier?”
Rin raises his eyebrows, peering into the plastic bag with a frown on his face. “Why did you bring home a bunch of gum, butterscotch, toothpicks, are these cigarettes? Really? And a pacifier.”
You probably should have just stuck with the gum. Even the toothpicks would be pushing it. “Suprise..?” You meekishly let out, afraid of the outcome.
“This is for me?” Rin questions, setting the bag down with a sigh, and turning to you with a blank stare.
“Well one of us has an oral fixation, and its not me,” You say, watching the way your boyfriend immediately flushes red, and looks away.
He pinches the bridge of his nose and sighs. “And where did you get that idea?”
You lean in closer to him, grabbing the bag with a huff. “From the weeks of you constantly having something in your mouth. After the fourth time of you pulling away from me, mid makeout session to spit out your gum, I figured something was up. And the internet is free you know.”
He peers at you, and doesn't say anything. You were right of course, but he was too embarrassed to admit it. Nor the idea of where this innocent fidgeting thing led to. “So you bought me cigarettes and a pacifier?” He accuses, tone harsher than before. It was unexpected how angry he got over something like this.
“I'm just trying to help you. What do you want me to do, stick my fingers in your mouth or something? Fuck, you dont got to be an asshole about it,” You quip back, growing annoyed at his behavior. He was being a brat for no reason, and although you did give him stupid gifts, he didn't have to be rude about it.
He glares at you, taking a step forward toward you. “Yeah? Maybe you should. Stick your fingers in my mouth, like the disgusting pervert you are.”
You bark a laugh at him. “Of course you make this sexual! Maybe I should, shows how desperate you are for a little attention,” You hiss, grabbing at his shirt and pulling you closer to you. You forcefully open his mouth and shove two of your fingers in. He gags, glaring up at you from under has lashes from the mere forcefulness.
You press the pads of your fingers to the roof of his mouth, his head tilting upward from the pressure. “Does this fucking help? Maybe I should just do this for….” You trail off, the bite in you dying down when you feel his tongue graze your finger. You begin to pull away, but he grabs onto your wrist, forcing it inside. “You really…Wow, okay,” You mumble, staring at your boyfriends now half lidded eyes.
He glances up at you, cheeks slightly flushed from embarrassment, but he would never admit that to you. Instead, he just mumbles, “Shut up.” which comes out a little garbled, making the complaint just sound cute.
You lead him to the couch, and motion for him to kneel on the carpet below. He glares at you, nipping gently on the tips of your fingers at the idea. “What? Obviously you are enjoying this way too much. So if you want my fingers in your mouth, then you can sit on the floor. You are too tall, I'll grow tired from reaching up,” You reason, fighting back the urge to roll your eyes as he continues to gnaw on your fingers in complaint.
He thinks about it for a second, and finally decides that you are right, so he takes his spot in between your legs, still holding onto your wrist like he is afraid that you are going to pull your fingers away. You pet his head, and finally relax your hand, your fingers falling limp on his tongue.
It doesnt take him long to start gently suckling on them, his tongue gently roaming around the two digits. You watch with amusement as his eyes grow heavy, and the thoughts seem to leave his brain. He looked so content like this, it was fascinating. The usual frown on his face gone, and drool beginning to bead at the corner of his lips.
“Mwove ‘em,” he demands not after long, and you bite back a laugh, knowing that his personality hasnt done a complete shift. But you abide to the command, and drag your fingers over his teeth, pressing them against the wall of his cheek, admiring how cute he looks when his lips are forcefully dragged to the side.
He takes notice to this and bites you again in warning, and this time you do laugh. “So temperamental, Rin. Thought you wanted me to move them around?”
“Dont make fwun of me.”
You hum, and use your hand to brush away his bangs. Then, you continue your exploration in his mouth, accidentally jabbing your fingers too far back, making him gag. You wince, apologizing immediately, but he doesn't say anything, gripping onto your wrists and pulling them deeper into his mouth. “Fuck Rin…This is....Kinda hot,” You murmur, cupping his cheek with one hand and plunging your other fingers deep into his mouth just to watch him gag again.
At your words his blue eyes flicker downward to his pants, and you follow them to see his hard on pressed against the fabric. You let out a breathless laugh, and put your finger to the top of his mouth again, forcing him to look up at you. His eyes are watery from the gagging, but other than that, he looks completely blissful, staring at you with hearts in his eyes. “Aw, this isn't bout your little oral fixation anymore, is it?" You taunt, narrowing your eyes at him. "You just wanna be face fucked, yeah Rin? Want me to abuse your pretty mouth until your throat is all bruised up and you are drooling all over the place?”
He gags again when your fingers travel back deeper in his mouth, but he doesn't say anything. He looks at you again, flushed in the face, and nods once, looking away immediately after. You play with his bottom lip, and grin at him. “God you're so pretty,” You praise, and he gulps, cock twitching in his pants.
Your fingers seem to travel every inch of his mouth, and his tongue follows them around, licking at them, even when you scold him to relax. Then, you begin to move your fingers in and out, and he gags with each thrust, tears dripping down his face as he forces his eyes shut. You listen to the gross sound of his throat being abused, and stare at him, completely fascinated about how hard he is right now. How something as strange as this could turn him on so much.
Suddenly, you grab his tongue and pull it out of his mouth. He winces at the harshness, and stares at you, slightly afraid of what's to come next. He feels vulnerable in this position, which he rarely feels, so he begins to squirm unconsciously. You lean forward, curling yourself over your legs and just above his face, the shadow of your frame darkening his face. “Hey Rin?” You whisper darkly, running your thumb over his tongue teasingly.
“Hmm?” He tries to hum, fists clutching onto your pants. He feels his tongue begin to dry up, and the force of your hold is uncomfortable, but he can't help but be extremely turned on. It was better than he imagined.
“Can I spit in your mouth?”
His eyes widen slightly, and his dick twitches in his pants. He takes a deep breath through his nose, and then tilts his head back, trying to open his mouth wider, but failing considering your hold on his tongue.
You grin at the action and lean forward just above his mouth, letting a glob of saliva fall from your mouth and into his. You release his tongue, and he immediately swallows, shivering at the feeling and the act of this really happening, all the while you coo at him. A couple seconds go by and he opens his mouth again, and you smile, seeing his tongue bare.
He trembles, repeating the scene in his head. Tears drip down his cheek, and drool coats his bottom lip, but he doesnt take notice to it, because all he can think about is how wet he is now.
“Oh Rin, did you soil your pants?” You laugh, and he grinds his teeth together, rushing to cover himself with his hands.
You grab his arms, forcefully pulling them to the side to see the noticeably dark spot directly above his crotch. Sure enough, Rin came from you spitting in his mouth. You feel blood rush to your groin, and you blink at him. “Oh god Rin, you fucking pervert.”
But before he could deny anything, you shove two fingers back into his mouth, and almost instinctually he begins to melt, already forgetting about the warm sticky feeling in his pants.
