Work Text:
Izuku couldn’t focus. He was too excited since he got a message in the middle of patrol, that his package was ready at the post office. It was a risky order but Izuku believed that he wouldn’t regret it. He was sure that he wasn’t the first or last hero that ended up searching on the dark web, but it still didn’t feel right. The thing was that he wouldn’t find what he wanted anywhere else.
And moreover this shop even had very positive reviews and also some videos as a proof that it wasn't a scam. That guy was really lucky to have such a great quirk. With just snapping his fingers while looking at photo of random person, he could create a voodoo doll of them. In normal society he would be shamed for this power, but in an underworld full of villains, thieves and killers, he was able to make a big money. Just one doll cost almost a year worth of Izuku’s salary. And like that he made a lot as a number four hero, quickly rising to the top. But Izuku never was really spending too much, so he had a lot in savings.
The rest of his patrol he spent buzzing as he wanted to be home as soon as possible. Ochako, who was sharing her patrol with him for the day, wanted to drag him to a bar with a few of their old classmates, but didn’t succeed. Izuku only shouted after her that he already had important plans and that he was sorry, before he zoomed outside of the agency building.
Just a quick stop at the post office and he was floating home with a large package in his arms. He didn’t care if someone saw him. It wouldn’t be the first time he was seen like this. His fans would probably just try to guess which All Might statue he bought this time.
They still thought about him as some inocent sweetheart, that didn’t know what sex even was. And god, how much far from the truth they could be. As if Izuku hasn't been jerking off to one specific blond since he was fifteen. He knew that he would never be able to get this close to Katsuki. During their time in UA they again became somewhat of friends but that was all. They just hang out together from time to time and even then it was mostly with other people.
And the second thing was that Katsuki was straight. It was a confirmed fact. In past years he went though a few relationships but it never lasted longer than three months. Katsuki still chased his dream of becoming number one hero and his girlfriends didn’t like that they weren’t his priority. But that was alright. Katsuki didn't need them. He didn’t know what he needed.
But Izuku was ready to show him. Even if he couldn’t do it in person. That was why he bought the doll. That even as straight he wouldn’t resist a pleasure caused by a skilled man. And Izuku was skilled for sure. Long nights in secret sex club prepared him well. His partners never left unsatisfied.
When he finally got to his apartment, he put the box on his bed and went to turn on his computer. At the same time as he placed the order, he also installed secret cameras in Katsuki’s apartment. It was so easy to do so. Since they were working at the same agency, there wasn’t any problem about finding out when he was away on patrols. And the blond always returned home so tired that he would be able to notice the small device even if he was looking right at it.
Izuku smiled as the screen showed a picture of the bedroom. It was around seven in the evening and Katsuki was getting ready to go to sleep. He had a day off tomorrow, but he stuck to his early bedtime every day. It was perfect. Izuku also took a quick day off, saing, that lately he was getting headaches and wanted to rest for at least that one day. It was completely a lie, but no one needed to know that.
When this was set up, he went back to his bed. Without getting a knife he tore the package and carefully took the completely naked doll out. It was beautiful, just as original. If it wasn’t so cold, someone would think that they were holding a real body. Silky blond hair, smooth skin that didn’t miss any of the scars Katsuki had, and piercing red eyes. Truly a masterpiece.
Izuku would love to see Katsuki’s eyes during it, but he had to close them. It was a thing that the seller was doing. The doll wasn’t active unless its eyes were closed. It was a good feature, since it prevented a situation when something would happen to the doll, when it wasn’t used, and the real person would end up hurt.
Izuku quickly took a shower and got everything he would need ready. By that time Katsuki was already undisturbly sleeping. Not for long though. It was such a good thing that Katsuki was used to sleep naked. It was something that Izuku appreciated in the past too.
Izuku wasn’t going to hold back. And it didn’t take more than a little bit of caress across the doll’s body to wake him up. He looked so cute. Confused, looking around and trying to find who was touching him just to see his room empty. Izuku sat the doll into his lap and firmly grabbed its chest. “What the hell?!” Katsuki choked out as his hands shooted to his pecs while he felt light kisses on the back of his neck. Izuku rubbed the muscles in his hand and then moved them to pinch the blond’s nipples. It made him squeak, and Izuku had to laugh. He was so glad that the cameras he got recorded sounds too.
Another thing that made the doll even better was that it responded to the real person's body. Like this Izuku could see how the fake dick was rising, indicating that Katsuki’s was unwillingly getting hard from getting molested by something he couldn’t see. “Such a naughty boy.” Izuku smirked. He was going to enjoy this.
When he grew tired of the blond’s pecs, he moved lower. Just for fun he ran his finger over Katsuki’s ribs and tickled him. The sweet sound of Katsuki laughing and begging it to stop filled his heart full. Next time he would get a feather.
Also on the screen Izuku could see that Katsuki’s dick got a little bit softer from the tickling but that was just what he needed. He had to show Katsuki that he didn’t need it to get the best orgasm of his life. That was why he bought a simple cockcage. Without problem he got it on the doll, preventing Katsuki from getting hard again. Even if he tried to stroke himself it would help and most likely would make it even worse.
Katsuki’s expression changed a little when he felt the unknown pressure on his cock, still not understanding anything. The purchase was already paying off and that was just a start. This position wasn’t good anymore, so Izuku laid the doll on his bed again. At least these movements didn’t affect the blond, then it would be a little bit weird and uncomfortable.
Now with the doll lying down, Izuku had more space to play. He didn’t hesitate to kiss every centimetre of the fake skin, running his hands freely and groping everywhere he reached. He was surely leaving marks behind him, not holding back with biting and sucking. He could hear how Katsuki was panting and shouting insults and threats into the air. By the end of their night, Izuku would have him a moaning mess, and begging for more. He just had to work a little bit more.
Once he was satisfied with the state of Katsuki's skin that he could see through the camera, thanks Katsuki that you turned on your lights by the way, he spread the doll’s legs. He had to move the soft cock to the side, so he would get to Katsuki’s ass. It looked so real as he grabbed the cheeks and spread them to reveal the hole between them. “Beautiful, Kacchan. I would never expect anything less from you.” Izuku sang him praises even when he knew Katsuki wouldn't hear them.
He was surprised when instead of angry shouting he got a loud moan when he playfully slapped the blond’s ass. So he was really a bitch that acted all tough but in the end loved being treated roughly. “You only dated strong women. Did you need a good dom for your cute subby ass, hmm?” Without thinking he kept slapping him. Giving to it all his strength without using ofa.
“What do you think, would you count them for me?” He smirked, giving him an exceptionally hard slap. Then he heard a mumbled word coming from Katsuki’s mouth. Izuku’s eyes opened wide and he let his hand fall one more time to test it. “T-Two..” Shaking voice came from the computer. Izuku had to grab a sheet next to him to calm down.
That little slut was really counting for him. If their friends and colleagues just knew that it takes only a few slaps hard enough to leave marks on his ass, to get Katsuki to this state. Or if the villains knew it. Then Katsuki would probably be quickly taken and transformed into someone's obedient pet. But only Izuku knew it. And he continued to enjoy every word said by the blond as he made his ass bright red.
He stopped only when they got to the number twenty and Katsuki looked as if he was about to pass out. From that angle Izuku could clearly see his teary face and chest going up and down in quick frekvenci. He looked like a dream. Izuku had to get him back to his senses.
Once again he spread his ass and with one finger caressed the little hole. He had to laugh as he saw Katsuki's eyes widening in panic. "No! Please not there! Not there." He pleaded. He probably never tried to go to this place. What a shame. That poor boy never experienced real pleasure. "Don't worry, Kacchan, you'll like it. I promise!"
Izuku tried to use more pressure on the hole to find out how the doll worked at this place. It seemed dry, but he expected that. He brought some lube with him so this wasn’t a problem. What was nice was that the hole was tight, not loose and pliant like most of sex dolls, that he got into his hands, had. You had to actually stretch this one before using, if you didn’t want to hurt the real person. And that was absolutely not what Izuku wanted. He wanted to show Katsuki pleasure, not pain.
So he scooped a good amount of lube and covered Katsuki’s hole with it. The blond was shaking. Even just from the video on the screen, Izuku could see how scared he was. He had to work quickly, not to stress him more than was necessary. Richly covered finger sunk inside and Katsuki yelped. “Shh, just a second.” Izuku searched inside for his target and knew that he succeeded when he saw that the blond stilled. Izuku took the finger out and again rammed it back right against the found prostate. Katsuki’s moan sounded surprised.
Izuku smirked and kept making Katsuki moan loudly. The blond was so lost in pleasure that he didn’t notice when his hole gradually swallowed two more fingers. Then everything stopped. Izuku took out all fingers and wasn’t touching the doll anyhow. “Wait! I-I…” Katsuki almost sobbed. Oh, did Izuku stop right when he was about to cum? Well that was bad for him. Izuku wasn’t planning to get to this point just yet.
He reached behind his back and grabbed something. It was a vibrator. It was smaller than Izuku’s dick, but it would work just fine. He pressed the tip to Katsuki’s entrance, not wanting to scare him by suddenly shoving it in. Only then he started to slowly sink it in. He was happy when he didn’t hear any sound of distress coming from the computer. Only panting. Katsuki probably calmed down since he found out that he could experience more than a simple pain coming from this place.
Izuku was teaching him new ways to be pleasured, and was happy that he had such an obedient student. Even if it was still surprising that he got so obedient so easily. Katsuki must have been sexualy frustrated. Maybe he couldn’t get satisfaing sex and that was why he was always so grumpy. All because he was too afraid to try something new.
Izuku turned on the vibrator and happily listened to more moans. He also stripped himself off the boxers he had on all day and laid them across the doll’s face. Not only touches but also the smell worked, so Katsuki could happily inhale Izuku’s musk, some precum and dried piss that stuck to his dirty underwear. “Alright Kacchan, it's time for a little break. I still need to fill out a report from today's patrol, but don’t worry I will be back in about an hour.” And like that he left the blond with a vibrator stuffing his ass.
Maybe it was a little bit evil from him, but he really needed to do that report. Just before he left the bedroom, he connected his phone to the video, so he would be able to listen to Katsuki while he was working. He sounded too cute. Whining and panting, vibrations teasing him. Izuku set them pretty low, so they weren’t able to make him cum. He couldn’t even think enough to realize that he could try to get to the climax from his side. Though his dick couldn’t get hard, his real ass was still free for use. It would only take to find some oil or at least use his saliva to slick it up. But that was his fault.
Izuku enjoyed listening to Katsuki’s pitiful edging. Just as he thought the work took him something over an hour to finish. This was his least favourite part of being a hero, but with the companion of whining and most likely crying Katsuki, it wasn’t that bad. He shoved the finished report in his bag, so he wouldn’t forget it at home when he would get back to work, and returned to his room.
He had to gush over Katsuki as he saw him on the screen. He was curled on his bed, arms hugging his legs. Without touching the doll, Izuku leaned over it and kissed its lips. Just to let the blond know that he wasn’t alone anymore. Then he reached for the vibrator and slowly took it out.
It would be so hot if he bought some type of vibrator that was powered from the outlet instead of batteries. Then he would be able to let it inside, turned on, for the whole day. Katsuki going through his patrol with phantom vibrations in his ass. Maybe he could buy some that even targeted the prostate. But the patrol might be too dangerous. It would be bad if Katsuki had to fight and got distracted by it. Izuku would never let him get hurt because of his fantasies. Some meet and greet with fans would do better. No villains, just a crowd of fans adoring Dynamight’s flushed face. Izuku made a mental note to search for the toy later.
Now, with fingers he tried how loose Katsuki’s hole still was and decided that it would be fine. He wasn’t wearing any pants since he put his underwear on the doll’s face. Which Katsuki probably really liked. Since Izuku put them there, he was breathing in exclusively through his nose.
With no clothes in the way, Izuku covered his cock with lube and kneeled between the doll's legs. “Your little hole is about to lose its virginity. Aren’t you excited, Kacchan?” He kissed the doll's neck before he slowly sunk inside. The blond raised voice, recognizing a very hot and very real cock instead of a cold toy. And he visibly liked it. Chanting ‘thank you’ into his empty room. It looked like the hour was too long for his aroused body, that it turned his brain into horny mush.
But Izuku was going to pay him off for the time he had to neglect him. Right from the start he was thrusting in the doll with full force. It wasn’t as good as fucking a real human, but the thought and image, that he was able to see on his computer screen, of what it was doing to the blond compensated it pretty well. “Such a noisy little thing. Don’t you care about your neighbours?” He wouldn’t be surprised if Katsuki got some noise complaints after this night. He would love to hear these sweet moans in person.
They were getting louder and Katsuki was getting closer to his orgasm at a record speed. Izuku knew that, after the hour of edging, he wouldn’t last for long. The camera couldn’t completely catch Katsuki’s face when he came, as he was still curled. But there was no doubt that it hit the blond strong. He surely never came with his cock fully soft before. With a spark of an idea, Izuku added to his mental list to look for some sounds in the shop. In combination with the cockcage it would be perfect.
After that Katsuki laid limp till Izuku also got to his climax. Filled the hole with everything he had. He was breathing fast, so overjoyed. He shoved the boxers from the doll’s head and looked at its face. Sadly, it didn’t have any facial expression. It looked like it was just simply sleeping. “One day, Kacchan.” Izuku whispered and kissed its lips. Then he opened the doll’s eyes, breaking the spell.
Just before he stopped the recording, he heard a soft voice. “What the fuck…” He laughed. It was still his Kacchan after all. But now it was time to clean this mess up.
Izuku chewed his lips as he watched the recording on his computer. The seller requested to send him a record of the first time using the doll for ‘marketing’ usage. But it was clear that they were just his jerking off materials. There were even two options. Let the video be public or private. And Izuku couldn’t decide if he wanted Katsuki to be seen by so many people.
No, the blond was his. Only he was allowed to see him like this. No one else. So he chose option to make the video visible only for him and the seller and changed the page to a sex shop. He needed new toys for his little slut after all. And maybe, sooner than he originally thought, he would be able to use them not only on the doll, but also on the blond himself.
