Chapter 12

Weddings. They’re supposed to be fun, romantic, emotional, and glamorous. Kirishima and Uraraka’s wedding was all of those things plus one very important thing: chaos. Pure Chaos. 

 

At first, the ceremony was beautiful with a minimal amount of craziness. They both liked their friends too much to pick specific ones. They all celebrated as a group then for the actual ceremony Uraraka chose Deku to hand her the ring she would give to Kirishima and hold her stupid bouquet or whatever. Of course, Kirishima chose Bakugo, because why not? He was obviously the best choice despite what Kaminari was saying. 

 

That part went over very well. Until it came time for the ring exchange, Uraraka was nervous. So nervous in fact, she accidentally activated her quirk and made the ring Deku handed her float. It took forever for her to remember to release it which caused the ring to plummet to the ground which led to everybody searching for it. 

 

Eventually, it was located and things got back on track. Ashido’s date was the one to find it. She was the girl they met the first time they went to the club, turns out they had the same soulmark. They didn’t realize until after they had sex for the first time which everybody else found hilarious. Personally, Bakugo thought it was dumb. Why wouldn’t you check for that first? The next few hours were full of fun and typical bickering among them. 

 

Unfortunately, it wouldn’t be on brand for the former class of 1A unless a villain attacked. It was one of the biggest gatherings of heroes since their former teachers attended, All Might himself made an appearance although he goes by Yagi Toshinori these days. That didn’t stop the students from calling him All Might or a villain trying to come after him. Needless to say, the villain was taken down. 

 

The entire thing was a hassle. 

 

Still, Bakugo imagined what it would be like to marry his boyfriends. He’d have to ask them to marry him first before one of those idiots beat him to it. 

 

/ / / /

 

They had moved in together, did the meet the parent's bullshit, and everything else. The move happened only a few months after they started dating, it didn’t make sense to keep living separately. They had known each other forever and were certain they didn’t want to break up ever. Meeting the parents happened soon after. Technically they had all already met each other's parents but ‘we met as friends, we need to meet them as boyfriends’ Deku had insisted. 

 

It went over better than expected, especially with Endeavor. The number one hero had been working on himself, attending therapy, couples counseling, and all that bullshit. When the three of them had come out to him and Todoroki’s mom, Rei, they were excited. Endeavor actually said, “my son pulled two of the most powerful heroes, I’d expect nothing less.” To which Rei Todoroki hit him. Surprising. Not that Bakugo actually gave a fuck. 

 

If Endeavor had an issue with it, Bakugo would have fought him. Even if he did admire the man as a hero, he was a shit father. If he had decided he didn’t accept Todoroki… anyway it didn’t happen so it was fine. 

 

However, the lack of acceptance is what got Bakugo into his current predicament. Some of their “fans” had decided they didn’t like their favorite heroes being gay. They mostly got over it when it was revealed that he shared a soulmark with Deku. A small faction had even surfaced about how “it disrespected their soulmark” to add someone who wasn’t their soulmate. Their PR team insisted they do a press conference to answer questions. Some asshole in the crowd decided to talk shit about their relationship. 

 

To be specific he said, “I don’t want some gay hero who takes it in the ass to save me.” 

 

In response, Bakugo grabbed him and threatened to blast him in the face. He started begging Deku and Todoroki to save him since they were the only other pro heroes present. 

 

“No, don’t fucking ask for help now. You don’t want some gay hero saving you right?” He’d snapped at the man. 

 

Needless to say… it didn’t go over well. The man apologized and true Dynamight fans weren’t upset. They said it was very “on brand” of him to do. Actions have consequences though, as a result of his little stunt he was doing community service for two weeks. As if hero work wasn’t already community service. 

 

Luckily today was his last day. He was in the back of a taxi headed home when the buzzing started. Digging his phone out of his pocket, it was Deku calling him. A video call which was strange but not unusual. 

 

He answered. 

 

Todoroki was fucking Deku. The camera was set up on the nightstand which made him wonder how they called him in the first place. Deku was laying on his back, legs spread while Todoroki gently thrust into him. He quickly put in his Bluetooth headphones before the two of them could make any sounds the taxi driver would overhear. 

 

Just in time, Todoroki’s deep voice could be heard in his ear. 

 

“Go ahead Izuku, let Katsuki hear you.” 

 

His cock was hard instantly. He had to shift toward the door to hide it from the driver's view. The way Todoroki said their names was soft, filled with emotion. 

 

“Kacchan! He’s been edging me for almost an hour! He said I can’t come until you get home! Every time I get close, he pulls out!” Deku whined in his ear

 

Todoroki shifted them bringing Deku’s cock more into view. He could see the cock ring situated tightly around the base of Deku’s cock. The tip was red and leaking precum steadily. He really did want to cum. 

 

He watched as Deku begged and pleaded for Todoroki to let him come but he refused. He just kept slowly thrusting into Deku before stopping. The way he looked at the phone almost dared him to get home faster. 

 

“It’s okay princess, Katsuki will be home soon. Right?” His voice went up at the end jokingly.

 

He wasn’t even far away, ten minutes at most. That was ten minutes too long. He quickly pushed his dick down against his leg. 

 

“I’ll be there in less than five.” He hung up and tossed money at the driver before bolting out of the door. 

 

He took to the sky using blasts to keep him above the rooftops. If he got photographed hard in public that would be bad. Still, he wanted to be home NOW. It didn’t take long, he vaulted over the rooftops using his blasts to propel him forward. 

 

Checking the time it had taken him roughly two -  no - three minutes to make it home. He put the key in the door and punched in the code “333” which Todoroki had never changed even when they moved in. Usually, he loved the security but today it was another obstacle in his way. 

 

He made it inside and took his clothes off as he went, being stark naked was embarrassing at first but they’d seen him in some wild positions already. It didn’t matter, they were waiting for him. He’d be damned if he let some clothes get in the way. 

 

“You were faster than I expected,” Todoroki commented pulling out of Deku

 

His cock glistened with lube, he looked over to Deku laying on the bed, legs still open waiting to be pleased. Before he could go over to finish him off Todoroki was sinking down to his knees in front of Bakugo. 

 

“Damn Icyhot, I love when you get on your knees for me.”

 

“I know,” was the only reply he got before Todoroki was taking him into his mouth. He sucked him off in the front and groped his ass in the back. Bakugo wasn’t sure how he managed it but Todoroki was easing a slicked-up finger into his hole. He hadn’t noticed any lube before but at this point, he was too turned on to care. 

 

Looking down into those mismatched eyes he pushed a hand into his two-toned hair moving it back from his face. He could’ve come in his mouth, easily if Todoroki kept this up. 

 

Deku whined in the background begging to touch his own cock. Finally, Todoroki freed him, dragging him to the bed. 

 

He entered Deku’s gaping hole, his dick fit in there nicely despite Todoroki’s cock stretching him out beforehand. Deku practically screamed in pleasure at being fucked again. 

 

He swallowed the sounds by leaning over him to kiss him. Their tongues danced together as he fucked him fast and hard like he knew he liked. Todoroki only let him go for a few seconds before he stilled Bakugo’s hips and entered him from behind. 

 

Being full from the back and inside Deku left his movements limited, it didn’t matter though, Todoroki leaned back a little and forced Bakugo to move his hips. In this position every time he thrust into Deku Todoroki’s cock slid out but not all the way. Every time he thrust out of Deku he was filled back up by Todoroki. 

 

Deku had been constantly begging for release since they started, finally taking pity on him Bakugo removed the cock ring. Deku instantly came, it shot up between them coating them both. 

 

Now that Deku was done, Todoroki started fucking into Bakugo. Slamming into him from behind until Bakugo was spilling himself inside Deku. He pulled Bakugo off of Deku and turned him on his back.

 

They were laying side by side as Todoroki fucked him senseless. When he was done he pulled out and came all over both of them. 



“We really need to buy extra sheets,” Todoroki remarked, which caused a groan from the other two. 

 

Todoroki owned an American-style king-sized bed which was part of what prompted them all to move into his place. He already had a house and the biggest bed, it seemed logical. The problem was you had to order sheets specifically for the bed, currently they had two sets. However, they got the first set messed up already that morning. 

 

Stupid horny bastards. He grumbled but he threw both sets in the washer while they showered. Looks like they wouldn’t be getting sleep anytime soon.

Two years later  

 

Bakugo took his husbands to a tattoo shop. They sat there while Todoroki got the same mark they had tattooed on his hip. A blob similar to an ink splat in the same spot as theirs. Fuck the rules on soulmates. The three of them were meant to be together.
