Work Text:
Izuku held the coveted, limited edition Ground Zero dildo that had been molded from Ground Zero’s cock itself in his shaking hands. The dildo was black and had all the veins and curves of a real cock, including Ground Zero’s foreskin which was stretched back, as well as a pair of heavy balls attached to the base. The base was complete with a suction cup and on the bottom, it was embellished with a bright orange ‘X’. There were only 50 in existence; one was sitting in Izuku's cupped hands.
He took a deep breath.
In his head, he chanted: My name is Izuku Midoriya and I will fuck myself with Ground Zero’s cock. My name is Izuku Midoriya and I will fuck myself with Ground Zero’s cock. My name is Izuku Midoriya and I will fuck myself with Ground Zero’s cock. My name is Izuku Midoriya and I will fuck myself with Ground Zero’s cock.
Izuku released his breath. “My name is Izuku Midoriya and I will fuck myself with Ground Zero’s cock,” he said out loud.
The mood was set for tonight. He was alone in his small apartment. All the lights were turned off except for the string of fairy lights that were strung above his bed and he had lit a few candles that smelled like burnt toffee (he had it on good authority that Ground Zero smelled like that). His sheets were changed to plain white ones that would be easy to wash and his bed was adorned with a Ground Zero duvet and a 60 cm Ground Zero plush.
He had prepared his bedside table with a water bottle, lube in a pump bottle, tissues, and a damp washcloth. He had considered playing music (he read online it could be good to set the mood) but Izuku had a habit of getting distracted so he forwent that step.
The only thing left to do was undress and finally masturbate.
Izuku wasn’t shy to masturbating including anal play - he was a 24 year old gay man after all. He owned a decent collection of sex toys including dildos, plugs, vibrators, fleshlights, and even a few specialty items like a cock ring. However, he had never had sex with another person before and for some reason, this felt exactly like that. It was probably because the dildo in his hands belonged to his longtime crush, childhood best friend, and favorite hero: Bakugou Katsuki, also known as Ground Zero.
It’s not like Izuku didn’t want to have sex, it’s just that he was never in a position to. He was pretty shy despite his attractive, muscular physique. Even though Izuku was quirkless, he still had a lot of muscle from his time at the gym. He enjoyed working his body and feeling strong - he even taught self defense to teens in his free time. His legs were toned and he had thick thighs and well developed calf muscles, not to mention a great ass (in his opinion). However, his timid demeanor and general nerdiness staved off most guys (not that Izuku had ever actively looked for a partner before which was another glaring contributor to his virginity). But all of that was neither here nor there.
Izuku took another deep breath to clear his thoughts and repeated his earlier mantra. He could do this. He could fuck himself on Ground Zero’s cock.
Izuku placed the Ground Zero dildo carefully on his bed and hooked his thumbs into his underwear to remove them. He was in Ground Zero boxer briefs - they were black with an orange ‘X’ in front of his crotch and the words ‘GROUND ZERO’ were printed across the back. He had been wearing them all day in preparation for tonight. He shimmied the soft cotton underwear down his legs and stepped out of the materiel.
Last night when he got the notification that the dildo would be delivered the following morning, Izuku had made the executive decision during his planning (see: sexual fantasies while jerking off) to keep his limited edition Ground Zero shirt on.
It was from the first official merch release following Ground Zero’s debut. It was made of super soft material and because of the limited quantity, Izuku had only managed to snag a 3XL size which was way bigger than what he needed. The off-white shirt hung down to his mid thigh and depicted a cartoon explosion with the words ‘Ground Zero’ in comic book font imitating where the word “boom” would typically be. On the back, it read “Symbol of Victory” since Ground Zero had been taken under All Might as a second successor behind Lemillion.
Izuku loved the shirt for many reasons but mostly because on the inside tag, there was a doodle printed there that Ground Zero had drawn himself. Each shirt tag from the initial collection had a unique doodle and Izuku’s was a little bunny. It felt like it was made for him.
Izuku crawled on the bed, placing himself in the middle of the orange ‘X’. He had previously adjusted his pillows so all he had to do was lean back into the propped position. He pumped lube into his hand, took a deep breath, and opened his legs.
He shivered as his cold slick hand made contact with his cock. He was already a little swollen from excitement but the hand on his cock made it even more real. He wrapped his fingers around himself and began pumping his member to full length. He worked at a leisurely pace, gently working himself in his hand until his cock filled with blood. He twisted his wrist a few times and let out small sighs from the feeling.
It was time to move on to phase 2.
Izuku kept his left hand around himself while he reached out with his right hand to pump more lube into his waiting palm. He rubbed his fingers together against his palm, slicking his digits so that he could begin working himself open. He continued his lazy strokes with his left hand while he spread his legs further apart.
He brought his fingers down and first began by pressing his perineum. The sensation added to the intense need growing in his groin and he decided it would be best to move on. He began swirling his fingers around his hole. Izuku wasn’t really into shaving so felt small tickles on his fingers from his hair as he probed around his hole. A thought passed through Izuku’s mind about Ground Zero’s shaving preferences but he quickly chased those thoughts away.
The fingers tracing around his hole weren’t enough anymore and Izuku gave himself a few firm tugs to appease some of the need he felt. Then, he worked in his middle finger. Izuku played with himself often and when he was in a hurry he usually plunged in with two fingers but today was special. He wanted to take his time.
He forced himself to focus on the stretch of his middle finger as he fucked the finger in and out of himself. His hand was still working on his cock when he finally slipped in his pointer finger next. With two fingers it was easier to feel stretched out but he still wasn’t nearly full enough. He began letting out moans as he worked the fingers inside of him. He twisted them around, scissored them and he even allowed himself to find his prostate and give himself a few good rubs.
Izuku’s cock was becoming uncomfortably hard and from fear of coming too soon, Izuku released the grip on his member. He focused instead on inserting a third finger inside himself. He bucked against his fingers as the third made its way inside. He let out a shaky breath as he adjusted to the feeling then began thrusting all three fingers inside himself. He easily located his prostate again but made sure to avoid rubbing it too directly since he was already at risk of coming too soon. He continued fucking himself on his fingers for a few more minutes before deciding he couldn’t wait any longer.
Izuku removed his hand from himself and sat up slightly as he reached for the dildo. The Ground Zero dildo was sitting near his hip and he was comfortably able to reach it. He ran his fingers across the toy, marveling at its fine details. This is Ground Zero’s cock, he reminded himself. He followed a vein along the underside of the cock to the head. The black design was extremely elegant but he kind of wished the cock had been modeled after Ground Zero’s cock in color and material as well. Izuku ran a finger across the head and toyed with the slit. It was amazing it had been added too. Tentatively, Izuku brought the cock to his mouth and slipped his tongue right into the groove. He moaned and wished he could hear Ground Zero’s moans alongside his.
His tongue continued lapping at the silicone head but he eventually removed it from his mouth. He could suck it off another time - right now his hole was waiting.
He reached out to the bedside table and pumped more lube into his hand. Here goes nothing , he thought. He enclosed the dildo in his fingers and shivered at the touch. This is what Ground Zero’s cock would feel like . The cock was heavy in his hand from the silicone but he imagined the weight of the real cock in his palm while he stroked up and down the dildo. He was getting the dildo nicely lubed up in his hand and couldn’t help but picture Ground Zero right in front of him as he worked his cock. Would Ground Zero moan? No. he would probably hiss and cuss at Izuku to go faster. Izuku’s face flushed at the thought.
The dildo was now nicely lubed up so he brought it down to his hole. He hesitated before inserting it, he was hoping to savor the feeling of his favorite hero’s dick as it entered him for the first time. He opened himself up again on his left hand’s finger then guided the dildo to his hole. He massaged the tip around his asshole for a moment, whining at the feeling, then began pushing the cock inside.
The feeling was intense. Ground Zero’s cock was definitely bigger than his three fingers and was probably the biggest dildo he had in his collection. Izuku braced himself as the head of the cock entered his hole and he let out a groan at the feeling. “Ground Zero,” he sighed as he began pushing in the rest of the dildo. It was just what he had imagined and it felt so good.
It was easier, then, to get the rest of the dildo inside of himself. The dildo stretched his asshole wide and pressed heavily on his intestines. He felt extremely full and satisfied at the feeling. His neglected cock lay leaking on his stomach so he brought his left hand back around it. It twitched in his hand and for one heart-stopping moment, Izuku thought he would come. Luckily his cock continued to pulse without release. Izuku let out a relieved noise then went back to work.
The dildo felt nice resting inside of him but he needed more. He gripped the base of his cock so he wouldn’t come and began thrusting the dildo inside himself with vigor. The curve of Ground Zero’s cock was just right and the head passed by his prostate with each stroke. Izuku was letting out whimpers and moans with each thrust inside his hole.
He knew he was going to come soon so he figured he would just enjoy it. He released his tight grip around his cock and began half-heartedly fucking into his hand in time with the thrusts of the dildo.
He felt tears pooling in his eyes as the pressure in his lower stomach grew and he imagined Ground Zero leaning over him, whispering into his ear and calling him ‘baby’. Ground Zero would grip his hips tightly as he fucked into Izuku’s hole and suck deep purple marks into his neck. Ground Zero would play with Izuku’s cock and rub the precum all over his shaft. Ground Zero would play with his nipples and suck on the hard nibs.
It was becoming difficult for Izuku to concentrate on fucking himself with the dildo while jacking off and fantasizing. It would be easier if he didn’t have to worry about all three things at once. A sudden idea came to him and after another deep thrust, he removed the dildo with shaky hands, placing it beside himself.
He took a minute to collect his breathing then turned onto his stomach and reached out to grab his Ground Zero plush. He felt shame as he pushed it in between his open legs but as soon as he rutted into the soft padded toy, all those thoughts were forgotten. He patted the bed next to him, picked up the dildo once more then he reached behind himself and inserted the dildo into his stretched hole. He gasped as it entered him and moaned, “Ah, Ground Zero is so big.”
Once again, he began thrusting the dildo into himself in earnest. He didn’t have to worry about stimulating his cock anymore now that it was rubbing against the soft plush so he focused on using his hand to thrust the dildo into himself repetitively. He worked himself into a fast and rough pace, making sure to hit his prostate.
Izuku’s mind was beginning to become cloudy as he continued to fuck himself with the dildo and rut into the plush underneath his hips.
“Ground Zero! Please, Ground Zero! I love your cock! Ah! Please fuck me harder,” Izuku babbled. He had lost himself to the sensation. “Ground Z- Ah Kacchan, please! You fill me up so well Kacchan. I love your cock!” In his fucked out state, Izuku had slipped back into calling Ground Zero ‘Kacchan’ like when they were kids. It was ridiculous considering Izuku hadn’t said that name in years but it fueled his desire.
He continued crying out and babbling to himself while he fucked himself harder, chasing his release. The heat was tugging at his stomach, pooling in his cock and sending waves of pleasure through his body. On each thrust, he made sure to grind the head of the cock into his prostate and he thrust deeply into the plushie underneath him. He felt his orgasm bubble up in his lower back and spread out through his legs. He arched his back and rubbed helplessly into the Ground Zero plush. Right as he felt the peak of heat of his orgasm he heard two consecutive loud thuds at his door.
Izuku froze.
His cock ached underneath him and his hole twitched around the dildo that he had stopped moving inside of himself. The large orgasm he had been about to achieve had vanished but his body was still needy and ready to come. He held his breath, unmoving hoping the thud sound had been a fluke but then he heard a different loud bang.
He didn’t have any time to move off his bed and cover himself as he heard footsteps approaching and a shout resonated in his apartment. “There’s been a villain attack, we’re doing a civilian headcount,” the voice boomed into the space. Izuku was panting slightly, eyes wide in fear as the door to his bedroom was opened.
_____
Katsuki Bakugou was in awe at the sight in front of him. His childhood best friend, Izuku Midoriya was laying there in his shirt, with his covers on the bed, grinding into his plushie, and his dildo was shoved into him. The black and orange base contrasted nicely with Izuku’s brown, freckled skin, and it was only one of the many things about the scene that made his mouth water.
Izuku was eyeing him over his shoulder with tears in his eyes. Katsuki wasn’t sure if they were tears from pleasure or embarrassment. It didn’t matter though because Katsuki kind of liked them - he really liked Izuku.
Katsuki had been out on patrol that night as an "easy" shift. Yeah fucking right he had already captured 2 villains before he got a call to this apartment building where villains had apparently broken into a family’s unit and kidnapped their twin daughters. To top it off, the rest of the villain team was entering people's homes and releasing toxic gas - lethal if you were exposed for over 20 minutes.
Most of the scene had been taken care of by the time Katsuki had arrived and he had been tasked with clearing each unit on the 4th through 6th floor. It was a fucking waste for the number 10 hero to be knocking on doors but he did as he was told because if he made a scene his ranking would go down.
Izuku's apartment had conveniently been the final one in his sweep and of course the fucker didn’t answer his door. He had knocked (well, "knocked") but received no indication a person was in there and safe. So of course he did what he had to do and broke in - his agency did have money to smooth over this sort of thing.
What he wasn't expecting when he entered the apartment was to find the interior decorated with hero merch such as All Might figurines but most importantly his own merch decorating nearly every surface. What was even less expected was the sight in front of him.
Izuku whined from his position on the bed and rocked into the plushie (FUCK THIS NERD WAS FUCKING HIS CUTE CHIBI PLUSHIE). Bakugou was on Izuku in a flash.
He threw his gauntlets to the floor and ripped off the bulkier parts of his costume including his knee pads, boots, and neck brace. "What the fuck, shitty Deku?" he asked, as he crawled into the bed with Izuku.
Izuku hid his face in the pillow underneath him. “Please, Ground Zero,” he mumbled. He seemed embarrassed which was to be expected, Katsuki did walk in on him jacking it in what looked like a Ground Zero merch shop.
“Bet you fantasized about this huh?” Katsuki asked, sneaking his hand between Izuku’s legs and grasping the plug. “You probably hoped I would walk in and fuck you. You’re a shitty, horny fanboy, Deku,” Katsuki growled as he harshly shoved the dildo back into Izuku.
“Ka-Ground Zero!” Izuku called out, thrusting into plushie Ground Zero.
Katsuki smirked. This fucking nerd. He held the dildo expertly in his hand as he began fucking Izuku. “You’re all dressed up for me, Deku. Your room is a shrine for me and you,” Katsuki buried the dildo deep inside him, “you're my offering.”
Izuku cried out underneath him and nodded his head. “Yours, Ground Zero,” he gasped like the whipped nerd he was. Katsuki pulled the dildo out and began a rhythm of thrusting the dildo in and out while Izuku became undone under his hands.
Katsuki remembered when Midnight had approached him and asked if she could release a Ground Zero dildo for her line of hero sex toys. He had been adamantly against it until his management convinced him to do it with the bribe of a large bonus and a promise that doing this would make his ranking go up. It was still too early to tell about the rankings but he did have a fat check in his account.
The unexpected reward - and the best reward - was this: his biggest fanboy, Izuku “Deku” Midoriya fucking himself with his dick in his Ground Zero room. He would have to thank his management later.
Izuku was a mess on his bed. His tears were soaking into the Ground Zero duvet underneath him and his cock had smeared precum all over the plushie. Katsuki made a note to get a new one for him.
“Ground Zero,” Izuku whimpered, “Ground Zero fuck me harder.”
Katsuki brought his hand down to his crotch and began palming his cock. “Deku, you fucking hero cock slut,” he said, thrusting the dildo a few more times into him. “I’m gonna fuck you so hard, you’ll never need that stupid plastic dick ever again.”
Izuku mewled when Katsuki removed the dildo and Katsuki watched as Izuku’s empty asshole attempted to clench around nothing. He couldn't wait to get his dick wet and fuck Izuku’s brains out properly. Katsuki quickly stood up and ripped off the rest of his hero costume before climbing back into the bed.
He mirrored Izuku’s position on the bed and came properly face to face with Deku for the first time that night. “Hey,” he said with a mischievous grin, reaching a hand out and brushing Izuku’s sweaty curls from his face. Izuku was flushed a deep red and was hot to the touch, he must have been going at it for a long time.
Izuku blinked at him and turned his head away, “Hey Kacchan,” he muttered.
The sheepish tone of his voice made Katsuki giddy. “Oh now it’s Kacchan?” he teased.
Izuku let out a loud groan, “Shut up.” He shook his head. “I was just trying to get off, I didn’t expect you to be in my apartment. Or anywhere in a 100 kilometer radius of my home for that matter,” he said.
“Speaking of which you still haven’t gotten off,” Katsuki hummed. He ran his hand through Izuku’s hair. “I finish you off if you want,” he said.
Izuku sat up on his knees. The pleasure building up had dissipated some but he wasn’t opposed to properly reaching an orgasm after having two of the previous ones ruined. “I was kind of expecting you to ‘finish me off’ the moment you walked into the room and started fucking me with your dildo,” he said, wiping his hands down his shirt. The shirt had slipped down and was now covering his leaking cock and his wet ass.
“Well, let’s get to it then,” Katsuki said. He propped himself up on his crooked elbow and smoothed a hand over Izuku’s thigh. He dropped his voice lower to a seductive tone, “Let me show you how good I can make you feel.”
The words made Izuku shiver but before he agreed, he shook his head. “Kacchan I have to tell you something,” he said.
Katsuki raised an eyebrow. “What? You’re in love with me? Yeah, I can tell,” he said waving to the rest of the room.
Izuku flushed but managed to ignore the words. “I’ve never had sex before,” he admitted.
It was Katsuki’s turn to be surprised. The thumb currently rubbing circles into Izuku’s thighs stopped and he looked into Izuku’s eyes. “You? The sexy beefy guy has never had sex before?” he asked in disbelief.
Izuku’s face heated up more at the compliment as he shook his head. “I’m still pretty shy and well the whole nerd thing doesn’t really attract any guy,” he mumbled.
Katsuki nodded and continued rubbing his thumb into Izuku’s thigh. “If you’re not opposed, I’ll fuck you even if you are a damn nerd,” he said.
Izuku’s eyes lit up, “Really?”
Katsuki rolled his eyes. “Yeah nerd, my dick is fucking hard right now and so is yours. Why don’t we cut this out and I can finally fuck you into this bed and you can stop fucking assaulting my plushie, jesus christ.” Katsuki ripped the plushie off the bed and threw it on the floor. “Need to fucking burn that one, it’ll never recover,” he sighed.
Izuku had the decency to look ashamed, “Ah, sorry, Kacchan. I just got a little carried away.”
“Yeah, no kidding. Not stop talking and spread your fucking legs, you hero fucker,” he said. Izuku’s eyes lidded once again and the need he thought he had lost returned in full force.
He quickly laid back on the bed and Katsuki watched in awe as he pulled the shirt up to his chest, spread his legs, and took his cock in his hand, pumping himself a few times until he returned to full hardness. “Well, Ground Zero?” he said in an attempt to flirt with Katsuki.
It had its intended effect and Katsuki was moving forward, reaching over Izuku to pump lube into his hand and he began stroking his own cock. “Fuck, Deku. I’m gonna ruin you,” he growled. Izuku whined and spread his legs further, enticing Katsuki with his slick hole. Katsuki let go of his cock and brought his hands down to Izuku. Izuku flinched at the sudden feeling of fingers probing his asshole but forced himself to relax as Katsuki entered a finger into his hole. It was thicker than Izuku’s fingers and loosened him back up. Katsuki quickly added a second and third finger, not wanting to waste any more time.
Izuku had rapidly become a blubbering mess under Katsuki’s expert fingers and Katsuki leaned forward and caught Izuku’s lips with his own while he continued to work Izuku open on his digits. Izuku was receptive to the kiss, opening his mouth and letting himself become pliant under the intrusion of Katsuki’s tongue. Katsuki began rubbing his fingers against Izuku’s prostate until Izuku was slack jawed and drooling.
“Looks like you're ready for my cock,” he smirked as he pulled away from Izuku.
Izuku nodded, the pupils in his eyes were wide. “Want Ground Zero’s thick cock.”
On another occasion, Bakugou might have made Izuku beg for it. He might have leaned forward and taken Izuku’s cock into his mouth and made him come before fucking into him nice and slow. But he had waited all night and practically his entire post-pubescent life to be in between Izuku’s legs and he wasn’t going to miss the opportunity by being too much of a tease.
Katsuki took himself in his hand and gave himself another tug before he lined himself up with Izuku’s hole. He was met with little resistance as he finally sunk into the tight hole he had spent half his life fantasizing about.
_____
Izuku and Katsuki both let out moans when Katsuki bottomed out. Izuku wasn’t sure what to expect from his first time (he definitely hadn’t expected his childhood crush to barge into his room and offer to fuck him, that’s for sure) but this feeling was better than any other fantasy Izuku had ever come up with while jerking himself off. He had a real life cock inside of himself and it was attached to the hottest person alive. To make things even better, Katsuki fit into him snuggly which was a million times better than any silicone dildo he had ever had.
Izuku could feel Katsuki throbbing inside of him and it was utterly amazing. Katsuki was definitely enjoying himself just as much as Izuku was judging from the facial expressions he was making.
“Please, Ground Zero,” Izuku whined, wiggling his ass.
Katsuki took the hint and gripped Izuku’s hips tighter while muttering something about him being a slut. He pulled out all the way then thrust his hips forward and buried himself back into Izuku, narrowly missing his prostate. Katsuki repeated the action, this time hitting his target and Izuku let out a cry of pleasure.
“You feel so good Ground Zero. Better than the dildo,” Izuku began his ramblings as Katsuki started thrusting into him with renewed determination.
He reached between their bodies and took himself in his hand. This time Izuku was going to finish, that was certain. He began fucking into his fist at the same time as Katsuki’s thrusts. He felt euphoric as endorphins continued to flood his body and he felt buzzing through his veins. This was it, he was finally going to come.
Katsuki leaned forward and used his right forearm to hold himself up over Izuku as he continued to fuck him deeply. He leaned further into Izuku’s space and licked a stripe up his neck to his ear. “You enjoying this, fanboy? You like taking Ground Zero’s cock up your ass?” Izuku threw his head back and let out a loud whine. Katsuki egged him on. “Yeah, you take my cock so well. You could never be satisfied with that cheap ass dildo. You need me here.” He brought his left hand to Izuku’s nipple and began playing with the hardening bud and Izuku cried out.
“There you go, baby. You gonna come on my cock for me? Want me to fill you up so you can have Ground Zero’s seed in you? Maybe I’ll plug you up and you can keep me inside you.”
Katsuki’s thrusts were beginning to become erratic which was fine by Izuku because he was just about to tip over the edge. “Kacchan, Kacchan,” Izuku sobbed, rubbing himself harder.
Katsuki’s gruff voice was right next to his ear when he said, “That’s it, nerd, come for me like a good boy.” And Izuku was coming.
He shouted Katsuki’s name as his whole body was overcome with pleasure. His thighs, back, and arms tensed. His toes curled and his fingers shook as he released copious amounts of cum on himself and Katsuki. He had never come harder in his life.
Izuku’s spasming ass was what pushed Katsuki to the edge. He squeezed his eyes closed and pressed his face into Izuku’s neck as he came with a deep guttural moan.
The world stopped momentarily as the two collected themselves. Bakugou had enough sense to pull out and roll over before his body collapsed next to Izuku’s. Izuku closed his eyes and was spending time trying to catch his breath. He had been so excited to fuck himself on Ground Zero’s cock today, he couldn’t believe he had actually gotten the Ground Zero’s cock.
Between Izuku and Katsuki were many unsaid feelings but that was for another time. Izuku let his mind drift in his post orgasmic haze and fell asleep curled up next to his favorite hero, Kacchan.
When he woke up the next day to Katsuki standing in his kitchen in nothing but an apron, he couldn’t have been more thrilled.
