“Truth or dare?”
It was a childish game, but ever since you played it at Halloween in first year, it had become a yearly tradition. In those few years so much had happened; AFO was defeated midway through second year, Izuku and Katsuki didn’t hate each other anymore, and best of all you and Shouto got together.
For a relationship born from vigilantism and war, you were going strong. There was only one hiccup you had: Intimacy. Every time the atmosphere got too heavy, either someone else interrupted, or one of you became nervous and stopped the interaction. Neither of you had a problem with the other’s boundaries, and being practical people, you’d discussed consent and what you might be into in the bedroom. You’d just... never got around to the actual sex part.
You said you liked the idea of being told what to do and being of service. Shouto said that was fine because he didn’t have any preferences other than being a bit more in charge. But those discussions happened a while ago, and you’d found out a few things about yourself in that time, like when you jokingly called him Sir. That had ended with you in his lap, interrupted by Denki knocking on the door asking you for help with his homework.
“Truth, I know how you are you little shit.” Mina said, and you didn’t blame her. Last year, Hitoshi dared Hanta (who was dressed as Spiderman) to tape shut all the doors and windows on class B’s dorm building. Mr Aizawa was so angry you could’ve sworn he’d tar and feather Hanta himself, you had a feeling he got off light because it was Hitoshi who dared him to do it. Their father-son dynamic was no secret, and good thing it wasn’t because his costume being Eraserhead certainly wouldn’t keep it on the down low.
“Is it true that you had a thing with that Shiketsu girl Camie?” By the way Mina pulled down the hood of her sexy Fat Gum costume and groaned, you knew the answer. “How did you find out about that?” But all she got in response was a motion of zipping his lips. She rolled her eyes and scanned the class for the next target of her schemes.
You looked at Shouto, your legs were draped over his lap, and he absentmindedly rubbed circles in your knee-high shoes. Everything was accurate to Mirko’s hero costume, even the small amount of coverage on your thighs, and your rabbit quirk meant it was only the natural decision. In contrast, your boyfriend’s Principle Nezu costume covered him head to toe in a dress shirt and pants, with a waistcoat that showed off his broad chest. He even had ears and a little tail on at your own insistence that he couldn’t just go to a Halloween party in a suit.
You couldn’t believe that out of all the clothes you’d seen him in, dressing up as Principle Nezu is what got you going. The way it all hugged him so perfectly, and how his sleeves were rolled up to expose his strong forearms; you felt like you were seeing him for the first time. His rough hands trailed slightly higher on your legs, tickling your lower thigh, you couldn’t help but shiver. It earned a huff of amusement from Shouto, who glanced sideways at you as if to say ‘Really? You’re worked up now?’.
You forgot all about truth or dare until Mina said your name, apparently having decided on a victim. Nobody would’ve picked a dare from her, but it was your third year, and it was probably the last Halloween party everyone would be there for, so you threw all caution to the wind.
“Dare, I guess.” You almost regretted it when there was a collective ‘ooooh’ from the group, not to mention the grin on Mina’s face. “Wellll... I dare you to spend 7 minutes in heaven with Shouto.” Katsuki let out a loud sigh in annoyance, evidently not enthused about the most boring couple to him being locked in a supply closet.
“They’re not even gonna do anything you know. They’ll probably just kiss with their eyes open and then organise the cleaning supplies.” That got a good laugh from you, but your boyfriend just stared at Kat with a challenging look on his face. Mina waved away his words and explained the rules: Both of you would spend 7 minutes in the supply closet just metres away from the lounge area, the rest of them would continue with the game but when the timer went off, the closet would be opened, and you’d only be given a ten second warning.
Shouto lifted your legs off him and stood, offering you a hand. When you took it, he pulled you up quite suddenly and snaked an arm around your waist, walking you down the hall. A few wolf whistles were all you heard before the door was closed behind you. The only light was from the full moon spilling in from a small window, bathing everything in a dim, white glow. “So, wh-”
“Knees. Now.” You obeyed immediately, knees thudding on the ground. He leaned back against the shelves, parting his legs enough for you to shuffle forward in between them. Shouto looked beautiful in the light, but his stern eyes told you not to say as much. It was probably Katsuki’s teasing that brought about that side of him, eager to prove his friend wrong to you.
“Do you want to continue?” His features softened and a hand came up to hold your chin, stroking your cheek. The impractical Mirko outfit you were wearing meant it was unlikely that you’d be getting anything in return, but you didn’t care, you just wanted to give. At your nodding, the hand in your hair moved to grip your ears, squeezing slightly as warning.
“Yes, Sir.” You breathed out, and he seemed satisfied, stroking your ears instead. Biting back a moan, you squeezed your thighs together in search of relief. Shouto took off his waistcoat and loosened his tie, looking down at you expectantly. Hurriedly, your hands came up to unbuckle his pants and work them down enough to reveal his boxers, with his hum of approval, you slid them down too. He was already half-hard, and you took him into your hand carefully, afraid you might hurt him.
The breathy sound he made was encouraging and you sat forward to lick a stripe from base to tip. That earned you a groan, and he pulled your ears upwards. It hurt the sensitive appendages, but you couldn’t control the whine you let out. You didn’t exactly know what to do with the dick in front of you, but figured you should keep using your mouth if his noises were anything to go by.
This time, you focused your attention on the pink head, licking a drop of precum off the slit. Stroking the length, you took the head into your mouth, swirling your tongue around it. You weren’t sure how much more you could fit into your mouth and just opened wider to move up and down. Shouto’s free hand discarded the ears you forgot he still had on, then threaded into your hair, tugging lightly to bob your head for you.
“Breathe through your nose, I’m close.” You pulled yourself off him and looked up with saliva still on your chin. “Do you want me to swallow when you do?” He nodded, pupils blown, and coaxed you back to wrap your lips around him. His right hand stayed tugging on your hair, and you could feel your scalp get cold as he forgot about his quirk, and he retracted his left to avoid burning your hair. When he unbuttoned his shirt slightly you could see that his whole left side was smoking.
Your head was pulled roughly to take all of him, and you swallowed as he emptied himself into your mouth, heaving with effort. Tucking himself back into his boxers, Shouto sank to the ground, and lifted you into his lap, knocking several items off the shelves in the process. He kissed you softly, deepening the kiss as you grew desperate for more of him. Those strong arms lifted you again, settling you to straddle his left thigh. He leaned forward to nibble at your neck, murmuring against your skin.
“Want you to come on my leg, think you can do that for me?” As if to encourage you, his hands on your hips ground you onto his thigh as he bounced his leg. You fell forward with a high-pitched moan, his teeth still licking and marking your neck. “Humping my leg like a bitch in heat, how embarrassing.” Shouto’s voice ran smoothly through your spine, and you whined at his teasing words. With an amused sound, he reached back to stroke at your tail, pulling on the fluff. You squeezed your legs and rocked into him harder, coming on the bouncing of his thigh. Just as you were floating down from your high, someone knocked loudly at the door.
“Alright, ten seconds to get decent!” You snapped your eyes open and scrambled off Shouto as quickly as you could.
“10, 9, 8, 7, 6...” Mina’s glee was evident through the door, as she counted far too fast. You grabbed at the knocked over containers, stuffing them into no doubt the wrong places on the shelves.
“5, 4, 3, 2, 1!” Shouto was zipping up his pants right as the doors were thrown open, and a noticeably drunker Mina giggled at his state of undress. “Hope you kids had fun~” She slurred, leading you both back to the lounge area, hand in hand.
A chorus of whistles followed your re-entry, and you went to sit in your previous seat before being possessively pulled into your boyfriend’s lap. “Geez what’d you do to her half-and-half, sounded like a whole lotta torture.” You covered your face in embarrassment and groaned into Shouto’s neck. “Looks like a whole lotta torture too, you a vampire or something?” Katsuki gestured to your neck with a wave of his hand. You almost laughed at how much cattier he was after a few drinks.
“No, we kissed with our eyes open and organised the bleach.” You were glad that everyone’s laughing drowned out your cackle at Shouto’s deadpan response, and his arms wrapped around your waist lovingly.
Maybe you wouldn’t mind if this continued past high school.
