Work Text:
Working at Fatgum's agency, he learned long ago about your oral fixation. It wasn't a need to have something to replace a needed smoke or anything, just a deep urge to have something in your mouth all the time. He learned shortly after that as much as he'd offer food to help offset this urge, you would politely decline nine times out of ten because you weren't hungry. While at the agency, pens would often find their way past your lips and between your teeth, and Fats would find himself politely looking away with a dusting of pink on his cheeks. While out on patrol, while the larger man munched down on various foods, you'd try out various snacks yourself so he'd feel less self conscious about eating when you weren't.
Sunflower seeds often led to a sore spot between your lip and gums, gummy snacks wouldn't last long enough to satisfy the urge, but one day you found the perfect treat: suckers. The red ones were your favorite, mostly for the flavor they provided, but FG liked them because of the color they'd stain your lips and tongue. He'd make sure you stayed well stocked on your favorite snack, and while he wouldn't tell you why, he secretly hoped that you knew it was because he would think of the way your tongue would circle and lick the round ball until nothing was left, how sometimes when you pulled the sucker out to talk to him and gesture with the candy that a string of saliva would stay connected for a moment before breaking, and he'd recall these moments late at night while fucking his own fist.
After the third time he buys you a bag of red suckers (and red hard candies to suck on while at the agency too, to save you from another pen mishap), you figure out his game and decide to make a show of it. Getting a shake from one of the shops he stops at, only to tie the stem into not one or even two but three separate knots. You don't question when he pauses for a moment in the middle of patrol after doing that to him, but you almost expected him to need more than two minutes to will away the hard on you were sure he had.
After three months of working with Tai, and so many bags of candy being bought for you and your oral fixation, you still haven't told FG that you know his secret. You're pretty sure he knows that you know, because the candies have narrowed into just the suckers now (because you both know it leads to more tongue tricks that way for both of your enjoyment) but neither of you acknowledge that the other knows. One day, while Tai had Kirishima and Tamaki covering patrols for him so he could stay in and work on some long overdue paperwork, you decided to stay inside with him. Kiri and Tamaki could handle themselves out there, they were decent pro heroes now, you knew not to worry and that they'd call if they needed backup. It was a slow day for crime anyways. You were working on your own paperwork, (and by that you were doodling in a notebook while finishing off a sucker and glancing sideways at Tai now and then to make sure he saw you).
Five minutes after you knew the stick was clean and starting to get soggy, you tossed it in the trash and reached for another sucker to replace it. (Since Tai started feeding your fixation, no pun intended, it ramped into a higher gear for sure.) Upon finding the bag empty, you simply shrug it off. You stand from your desk and venture to Tai's, knowing he usually has snacks in his desk to share. Upon reaching the side of his desk though, he looks up at you and gives you a sheepish grin.
"Sorry gummy bear, I'm fresh out. Was gonna make a snack run after work tonight. Think you can last that long?" You don't have much of a choice, so you simply nod and walk back to your desk. Half an hour later, your leg is bouncing erratically and you refuse to chew on a pen because you don't want your shirt covered in ink again (it is a bitch to clean out) but you don't have anything to stick in your mouth to solve your need to chew.
Tai is watching your ever growing fidgeting with great interest. He had purposely run out his snack supply, and hadn't refilled your supply either because he finally decided to take your little game to the next level. He knows it's simply a matter of time before you come back to him and request something, anything to help satisfy the fixation craving you have. Twenty more minutes pass before you're standing up from your desk again and walking with purpose towards his.
"Want me to make a snack run big guy? I don't mind going." In the back of your mind you're hoping he says no, you know what you want to fill your mouth with and it's not candy but you don't know how he'll take it.
"I think the nearest shop is closed, some kind of family event going on." It's an obvious lie and you both know it, but now Tai has laid his cards on the table. You know he wants to take your game up a level, and you're all too happy to oblige.
"Well, is there anything else I can stick in my mouth before I start chewing on my desk? I don't care for the taste or texture of wood too much." You can see the blush coat his cheeks a moment before his legs shift under his desk. It was now or never, and the worst he could do was say no, but you were fairly sure what his answer was going to be. "I can help you out with that if you'd like, sir. I need something in my mouth please or I'm gonna go insane." The blush on his cheeks deepens and he looks away for a moment, and the air grows tense for a long minute before he scoots his chair away from the desk. Quicker than lightning, you drop to your knees and slide between his legs to undo the zipper on his hero suit and let out his half hard cock. You don't need it at full mast, you wonder if it would even fit in your mouth at full mast, so this is perfect. You gently lick up the bottom, then wrap your lips around it and take it to the base.
Tai knows it isn't a sexual thing, not a hundred percent at least, so his cock remains partially hard but never full mast as you close your eyes in bliss of having the perfect thing to solve the oral fixation. After a couple of minutes to adjust, he figures out a good position to continue working on paperwork as you remain on your knees at his feet. Occasionally you'll swallow back excess drool, or his cock will twitch in your mouth, but overall it's a more relaxing experience for the two of you. Every so often he'll drop a hand to pet your head or move a strand of hair into place, and he would swear you're asleep if not for the swallow that usually follows him moving about.
He'll check in now and again, make sure you're doing okay, that you can still breathe and that your knees aren't hurting too much. (He vows to buy a nice pillow to keep in his desk for the future though, this will certainly become a more regular occurrence now that it's an option.) Every time he checks in, you nod or shake your head a little, eyes closed and brain slipping into that very nice fuzzy space you missed so much. After nearly two hours of cockwarming him, Tai's paperwork is finished and he knows he's going to have to go home and take care of things. He gently nudges you, and you open your eyes to look up at him.
"Time's up gummy bear. They're due back soon." You carefully release his cock (still half hard) and swallow back excess drool once more, then wipe your chin of the line that escapes. Slowly but surely your brain is returning, and color coats your cheeks at how forward you were before this all happened. "Maybe uh....maybe we could take this to my place after work? If you don't mind that is." His cheeks are just as red, one hand rubbing the back of his skull and you cover a giggle.
"I'd love that Tai. But maybe some dinner first?" He laughs out loud and nods, promising dinner first before any more fun.
