Work Text:
Somewhere at the beginning of puberty, Katsuki found out that when your sweat’s explosive and your palms sweat like a leaky faucet, using your hands to get off was incredibly dangerous. It only took one second of carelessness and he’d almost blasted his dick off. After embarrassingly skirting around the topic with Recovery Girl as to why he needed to be healed, he was left with a pretty interesting scar that started at the base and flared out to his hip as a permanent reminder of the danger his hands possessed.
At first, he thought maybe he could just ignore the need to get off, and for a while that worked well enough. The only casualty being his fuse was even shorter than it already was. But with hormones raging and the added stress of moving into the dorm, he found himself having to find some kind of a solution. Which is how he finds himself now as an adult with an old well-loved plushie.
He sighed, rubbing his face as he contemplated the old worn crimson colored teddy bear lying on the bed. As an adult, he had access to things he didn’t have as a teen, like fleshlights and even quirk-nulling gloves, but those always paled in comparison to the soft fluff of his plushie. He’d managed to keep his secret for years mostly by never letting anyone in his room. But now that his wonderful himbo of a boyfriend was moving in with him, he knew he had to be extra careful to keep it under wraps. Somehow he actually managed to keep the plushie out of sight for the first few weeks, but success had him growing careless. After all, if Eijirou hadn’t caught him yet, he was probably in the clear… Right?
“Fuck it.” Katsuki pulled his shirt off and ripped off his sweats. If he was going to do it, he had to be fast. With Eijirou’s shift ending soon, time was not on his side. If he was quick, he could wash it and let it dry for a bit before having to hide it again.
Quickly he made his way onto the bed, his heart was racing. What if Eijirou came home early and caught him? The thought shouldn’t excite him as much as it did. His heart thundered against his ribs, pounding in his ears as he hooked his thumbs in his boxers, yanking them down just enough to free half of his cock leaving it pinned to his body with the elastic.

Eijirou got home from patrol to find Katsuki cooking like he usually did, and after a kiss hello, he went to the bathroom to change into something more comfortable. Halfway through changing, he noticed an old-looking teddy bear hanging to dry in the shower. How cute! After pulling on his shirt he went over to the shower and ran his fingers over the soft fluff of one of the teddy bear’s ears, a warm smile tugging on his face.
“Hey babe,” Eijirou made his way back out to the kitchen “I didn’t know you kept a teddy bear from when you were a kid!”
Katsuki went rigid, he’d gotten distracted by cooking and completely forgotten to hide it.
“Just saw it drying in the shower, it’s so cute baby.” Eijirou wrapped his arms around Katsuki’s waist, cooing softly “So sentimental.”
Katsuki simply hummed noncommittally in response as he continued to cook. Nervous sweat built up in his palms that he nonchalantly wiped away with a kitchen towel. If Eijirou thought it was just a sentimental childhood thing, Katsuki was not about to correct him.
Of course, things became exponentially more difficult when Eijirou insisted it was okay for the plushie to sleep with them. That ended up leading to several restless nights of Katsuki staring at the plushie with his dick so hard it hurt. He was too preoccupied with his inner monologue in futile attempts to calm himself to notice that Eijirou had been watching him struggle.
See, Eijirou may be a himbo, but he knew that look in his boyfriend’s eyes. That all too familiar lust he’s seen directed at him plenty of times. It didn’t take long for him to put together that Katsuki wanted to fuck the plushie. So being the wonderful kink-positive boyfriend he was, he started bringing home random stuffies he’d find while he was out shopping. He didn’t want to pressure Katsuki into telling him if he wasn’t ready, but he could still indulge his boyfriend’s plushophilia (A term he learned while researching). He’d smile to himself anytime he’d catch one drying in the shower, something he knew meant his boyfriend had enjoyed it.

A few months after the initial incident, Eijirou rushed home excited. He’d managed to get his hands on a Red Riot themed bear! The marketing team had sent him one for his approval, so it was the first of its kind. He practically ran home with the bear stuffed into one of his oversized jacket pockets.
When he got home he rushed over to Katsuki who was lounging on the sofa watching some tv. He dropped to the floor in front of his boyfriend with an ear-to-ear smile.
“Babe you won't guess what I got at work today!” If Eijirou had a tail it would be wagging up a storm.
“What did you get at work love?” Katsuki chuckled reaching out to brush a stray lock of red hair behind his boyfriend’s ear
“Look!” Eijirou pulled out the stuffie and held it up for Katsuki to look at, “It's the first one off the line, they gave it to me to make sure I liked it and I just had to bring it home for your collection.”
Wordlessly, Katsuki took the teddy bear, turning it over in his hands to get the full view of it. It was a cute soft bear wearing Eijirou’s hero outfit, stuffed shoulder gears and all. He let his fingers trace over the details getting lost in the feeling.
“Do you like it?” Eijirou rubbed Katsuki’s thigh to pull his focus back to him
“Yeah,” Katsuki whispered dreamily before clearing his throat, “yeah, they did a good job, even got your stupid boots right.”
Eijirou smiled softly before leaning up to press a kiss to Katsuki’s lips “Glad you like it.”
As Eijirou left for the bedroom, Katsuki contemplated his predicament. He was so hard. The soft plush felt so good in his hands, he could already tell the texture was perfect. The second he heard the door click shut he couldn’t help himself anymore, he needed a taste. He quickly freed his cock from its confines and ever so slowly rested the toy against himself. He hissed at the contact, pleasure setting his nerves alight. He pressed it against himself a little more firmly and gave it a little test grind. He couldn’t risk cumming on it yet but that didn’t mean he couldn’t tease himself with it. It was so soft and fluffy. It was perfect. A little too perfect. It made it hard to pull the toy away when he got close but he had to. He couldn’t risk Eijirou catching him with the brand-new stuffie covered in cum. Shoving his cock back in his sweats, he did his best to calm down, his cock throbbing with want, his balls aching for release but he ignored it, opting instead to focus on making them some dinner.
Katsuki was good about not using the perfect plushie to get off, instead opting to rut against a different toy as he stared at it, pretending it was watching him. Pretending it was Eijirou watching him.
That was until Eijirou had a mission where he’d be out of town for a few days.
Katsuki spent the first few hours he was alone meticulously cleaning their apartment, doing anything he could to resist pinning the plushie to the mattress with his cock. The last thing he needed was for Eijirou to have forgotten something and come back while he was having his fun. So he kept himself busy until he got a message from his boyfriend that they’d made it to their destination safely. He sent back a heart and plugged in his phone to charge. After taking a deep breath to calm himself down a bit, he made quick work of stripping himself down. His cock already aching to get started.
He grabbed the Red Riot plushie from his pile tracing over all the details with the tips of his fingers. Slowly he made his way to the bed admiring the soft fur of the toy as he sat down. He let the fabric just barely graze his cock letting it tickle him gently. A soft sigh escaped him, his eyes fluttered shut, and finally, finally, he’d get to be as depraved as he wanted without having to worry about getting caught.
He leaned back and adjusted his grip on the plushy. He rolled his hips up slowly as he held the toy in place. He let himself truly enjoy the feeling as he imagined Eijirou holding the toy, forcing him to grind into it. No, no, Eijirou would make him flip over and hump it into the mattress like a dog. With the new scenario in mind, he flipped onto his stomach, wedging the toy between him and the mattress. He rocked his hips back and forth, a whimper escaping him.
What he wouldn’t give for Eijirou’s huge hand to press his head into the mattress. For Eijirou to settle in behind him and grind into him making him press harder into the toy. The thought alone had heat pooling in his gut, his clenched fists crackling and popping. He humped the toy desperately until he was a whining mess cumming all over its soft fur. But he wasn't done. No, he was just getting started. He rubbed his sensitive cock against the cum soaked toy, whimpering and whining as he worked himself over and over until he was unable to move.
He fell asleep still atop the cum soaked plush too tired to care about the puddle of cum under him. He did however wake up in the middle of the night sticky and gross. But despite how he tried to will himself up to get clean, his body had its own plans. The second his hips started to pull away, his cock was back at attention ready and aching for more despite how worn out he still was. Deciding he was too tired to get up to clean himself, he instead pressed his hips into the plushie again. All his cum soaking into the toy gave it a very different texture, and now it squelched on each down stroke. It should be gross. It should make him want a shower. But all he could think about was hearing Eijirou whisper in his ear, ‘That’s right my filthy little slut, fuck into your mess. Ruin that toy like I’m going to ruin you’
He had no idea how many times he ended up cumming but when he woke up he was still idly humping the toy. His hips seemed to have a mind of their own. He groaned, biting his pillow. His cock was so sensitive it bordered on raw. Unable to get his hips to stop, he rolled himself off the bed landing on the floor. He hissed as the cold air kissed his soaked cock making him shiver.
Sitting up he rubbed his face, cringing at the smell of burnt fabric that lingered on them. He assessed the sheets, aside from the huge puddle of cum, he’d burnt pretty sizable holes in them anywhere he’d gripped at them, even his pillow hadn’t escaped unscathed. He was going to have to throw them out. With a grimace, he grabbed the soaked teddy from the pool of cum and made his way to the bathroom.
After washing the bear a few times, it was finally clean again. Leaving it on the counter, he started up the shower. Once he was clean he could worry about disposing of the sheets and washing their mattress cover, but for now, he rested his forehead against the shower wall, enjoying the hot water for all it was worth before he had to get ready for work.

When Katsuki finally got back home it was already dark and he was beyond stressed. He toed his shoes off at the door and made his way to the bathroom. He was so tired, he even sat down to pee. He lingered on the toilet resting his head in his hands practically falling asleep. As he cleaned himself up his eyes caught sight of the toy now dry still hanging in the shower. Eijirou wouldn’t be home till later the next day so there was no harm in having some fun to help him relax. He washed his hands, drying them on a little hand towel before reaching for the toy.
Brushing his fingers along the soft fur, he headed to the bedroom. He flopped on the bed clutching the toy to his chest. It hadn’t even been 42 hours yet, but he already missed Eijirou more than he’d previously thought possible. He huffed softly, he was being ridiculous, Eijirou would be back soon. He should at least enjoy the solo time while he had it.
Grabbing his old red teddy from his pile he gently set down the toy next to the newer Red Riot themed one and began to get undressed. He took his time allowing himself to relax before he shifted to his knees and turned to face the headboard. He slid his old stuffie under himself, a moan escaping him as he rocked into the very familiar fabric. His cock jolted at the sensation, still sensitive from the night before. He pressed his cock down with his thumb keeping it flush against the toy, rutting against it. After a few strokes, he grabbed the riot plushie clutching it to his chest for a moment to ease his racing heart before he lowered it making the bears hug around his cock giving him the perfect plush hole to fuck into.

After their mission wrapped up faster than they’d expected, Eijirou pulled out his phone to message his boyfriend and let him know he’d be heading home. But even after an hour and almost at the halfway point, he still hadn’t heard from his boyfriend. He contemplated if something was wrong but did his best not to work himself up over what was probably just his boyfriend already being asleep.
When he made it home he was surprised to see the bedroom light on but figured maybe Katsuki had been too tired and fallen asleep with it on. It wouldn't have been the first time. However, when he quietly opened the door he was greeted with a beautiful sight
His boyfriend had his sculpted back to the door, thighs spread wide and ass cheeks clenching and relaxing as his hips rocked slowly. He was fucking into something but into what, Eijirou could only assume at this point.
“Hey love, I'm home.” Eijirou spoke gently as he approached the bed. His suspicions were confirmed as he caught sight of that familiar red fur.
“Shit.” Katsuki froze mid-thrust, ruby eyes flicking up to catch Eijirou’s expression expecting ridicule or rejection.
“Don’t stop, baby.” Eijirou encouraged, licking his teeth subconsciously, “I wanna watch.”
“Fuck…” Katsuki sucked in a ragged breath doing his best to regain some composure but he quickly got lost in those hungry crimson eyes.
“Keep going.” Eijirou leaned in letting his lips ghost over Katsuki’s “Show me.” he whispered before leaning in the rest of the way pressing a gentle kiss to his boyfriend's lips
After that surprisingly gentle kiss, Katsuki complied leaning back so Eijirou could see all he wanted. Embarrassment made his cheeks stay flushed but those crimson eyes watching him was everything he’d daydreamed about. Maybe he was just dreaming. Maybe he’d fallen asleep and this was all just a dream.
“Come on baby, show me how you want me to fuck you.”
That voice was pure sin when it was low and gravely like that. And well, he was helpless to deny it. His hips moved faster, his thrusts more forceful. He needed his boyfriend to truly blow his back out so he did in fact fuck into the soft plush hole he’d created the way he wanted Eijirou to fuck him. He needed it. Having his boyfriend way even just for the one night left him incredibly needy.
“Thats a good boy, now lean forward for me so I can get you ready”
He was far too eager to even consider hesitating. Immediately he complied, using one hand to hold the plushies around his cock as he used the other arm to brace himself as he stuck his ass in the air like the slut he was for his massive himbo.
And as usual Eijirou didn’t disappoint. His brain felt like it was leaking out of his ears as his boyfriend eagerly shoved that warm tongue right against his rim, lavishing it with licks and kisses until it finally breached him. If he came embarrassingly quickly from it, Eijirou didn’t comment on it.
The sensitivity after had him louder, made those calloused fingers feel absolutely divine when they finally joined in, spreading him open more. Thankfully he didn’t have to wait long before Eijirou deemed him prepared enough.
His boyfriend was quick to settle in behind him and push that thick cock into him and even quicker to set a harsh pace that left him breathless and whining. There was nothing he loved more than getting fucked like that. When Ei went hard and left him sore for the next few days he felt satisfied. Anything less just didn’t do it.
“When you get off by yourself, you’re going to send me a video of it. I want to watch every time you cum on them.”
A loud whine escaped him before he could stop himself. Fuck that was hot. He readily nodded in agreement. If thats what Eijirou wanted it was an easy enough request. Fuck, just thinking about it had him quickly racing toward that release. “Ei~” He moaned his hips rocking into the plushies with each heavy thrust of that thick cock that seemed dead set on abusing that little bundle of nerves.
When he came again, Eijirou worked him through it, getting the most from the orgasm as the pace slowed to a gentle rocking. He was sore and quite satisfied when his boyfriend pulled out so he was happy to just lay there as Eijirou quickly stroked himself to completion, his boyfriends cum splattering across his back.
“You good love?” Eijirou asked breathlessly, kissing along his shoulder
“Yeah, I want bath now.” he groaned softly as he slowly peeled his sweaty self off the sheets. He also needed to wash the plushies, they were soaked.
“I’ve got you baby.”
And like the lovely partner he was, Eijirou scooped him up peppering him with kisses as he carried him to the bathroom. Once they were soaking they could talk about this and he could let it sink in that his boyfriend not only now knew about his kink, but was clearly going to be very supportive of it. Until then he was just going to focus on getting as many little kisses as he could squeeze into the short distance.
