It was just an accident, when they were play-wrestling backstage and Senga tugged at Nikaido's necklace, and still it changed everything.

Nikaido gasped, and his eyes widened so much Senga was sure he'd hurt him.

“Shit sorry!” He quickly apologized, but Nikaido only waved it off and even blushed a little.

There was nothing suspicious about it.

There wasn't anything suspicious about how Nikaido seemed to let Senga win more often after that incident either. Besides, he looked good on the floor with his wrists pinned down by Senga's hands, a little flushed from their game. But Senga didn't think too hard about it, or at all, to be fair. There were other things to keep his mind busy, like single promotions and lives and Yokoo's nagging.

Senga didn't even think twice about how Nikaido always listened to him whenever he actually raised his voice, even though he hardly listened to anyone else, ever.

But then, things got a little out of hand. There was a party for someone's drama, and in the small hours, their bandmates made them kiss. It was only a tease from their group for always being so touchy with each other and Senga remembers Tamamori saying something about “resolve the tension~”.

Senga's not straight. But he likes girls a little more, most of the times, and as far as he knew then, Nikaido wasn't into boys at all. But now that he thinks about it, he's sure that kiss was the starting point of all this.

The kiss wasn't anything like what Senga had ever experienced before, hot and fierce like Nikaido's personality, but still not dominating in the way men often tended to be. They were both drunk, of course, but there was something in the kiss that made Senga feel dizzy. It was supposed to mean less than nothing, hell, Nikaido even had a girlfriend since 8 months, but in the end it meant way too much.

The day after, they both woke up at Yokoo's place, and when Senga asked Nikaido about the kiss and made sure nothing was awkward, Nikaido had looked away and said everything was fine.

After that, Senga started noticing some things about Nikaido's behaviour around him. Normally Senga would say call himself a sensitive person, but he must have missed out completely with Nikaido.

The way Nikaido touched Senga, and the way he let Senga do pretty much anything to him wasn't really on a friendship-level. And suddenly, when Senga told Nikaido about some girl he'd hooked up with, he noticed Nikaido's dark narrowed eyes.

“What?” Senga asked, totally taken aback and wondered whether that anger had always been there.

“Nothing.” Nikaido muttered, but Senga knew him way too well to believe it and pressed the matter. “I don't wanna hear about you and some girl, okay.”

Nikaido finally confessed, and Senga wasn't sure whether to feel offended or not.

“... Sorry.” Was all he said, and it wasn't until much later that he realised Nikaido had been so jealous he could hardly keep from clenching his fists in anger.

The tension built between them, Senga starting to feel awkward near Nikaido since he didn't understand what was going on, and Nikaido got more frustrated when Senga avoided him.

It ended up in something they should both regret, again alcohol involved, but this time at a club.

Somehow, they found themselves in the bathroom yelling at each other, and Senga's pretty sure Nikaido started it but he doesn't really remember.

Nikaido had been angry with Senga for avoiding him, and Senga had countered with what the hell was even Nikaido's problem with him. And then somewhere along the lines, Senga had shoved Nikaido against the wall and kissed him, and it was just as good as it had been last time, and he felt the frustration run off him. He felt a little guilty, but since Nikaido seemed to want it as well, he didn't complain, too drunk on alcohol and Nikaido's kisses to care about Nikaido's girlfriend. He felt a trickle of jealousy run down his spine when he thought that this, this was what she was getting all the time, and it made him press Nikaido tighter against the wall, twisting hands in his shirt, determined to take what he could get before Nikaido objected.

The only thing was, Nikaido didn't object. Rather the opposite. When Senga tugged him closer by the collar of his shirt, he moaned against Senga's lips and it was so beautiful Senga lost his mind completely.

Senga ended up with hands twisted in Nikaido's hair after he'd shoved him to his knees, with Nikaido's lips wrapped around his cock, and it was so hot and tight and fucking fantastic he couldn't bring himself to care about anything but Nikaido's mouth.

Nikaido had swallowed happily, looking up at Senga with adoring eyes that should have really clued Senga into what was going on. But somehow it didn't, and he just blamed not getting Nikaido off in return on not being able to think.

When he woke up the day after, he flushed dark red at the memory of it, so ashamed of what he'd made his best friend do that he couldn't even read Nikaido's name in the contact list of his phone.

But when he'd gotten to work after another day of shame, Nikaido was back to his ordinary behaviour around Senga, and it took weeks for Senga to learn that Nikaido had broken up with his girlfriend.

But that didn't help really. They didn't talk about the blowjob, not a word, until Senga couldn't hold it back any longer, too bothered by Nikaido not being bothered at all.

“I wanted to.” Was Nikaido's sincere answer, and Senga's jaw dropped. “You're hot when you're upset.”

And even though that might have sounded wrong to a lot of people, Senga was starting to realise what it was Nikaido found hot. He wanted Senga to loose his composure, get really angry or frustrated and not care about the consequences. Like that blowjob in the bathroom.

And once the thought got into his head, he couldn't get it out.

He noticed Nikaido provoking him, the few times he did, trying to make Senga angry, and he noticed himself falling for it more and more.

“What exactly is your problem!?” Senga finally burst after weeks of frustration, and ended up yelling at Nikaido in the middle of dance practise.

Everyone just stared in shock, since Senga and Nikaido never actually fought, and Nikaido looked as surprised as anyone, before dropping his gaze and mumbling nothing, sorry.

They finished practise with a cloud of tension between them, and if everyone threw a worried glance at them at some point, it didn't really help. After practise, Nikaido asked Senga to come home with him, and Senga easily accepted, figuring this would finally be the time they could talk about whatever strange thing this was.

But they didn't talk. Senga remembers trying to bring it up, but there was something about Nikaido, the way he didn't look Senga in the eyes, kept his answers quiet and dismissive, that made Senga's blood burn. Nikaido wasn't like this, he was loud and cheeky and that difference caused something to snap within Senga, and soon he had Nikaido pressed against his own mattress with Senga on top, kissing him fiercely while tearing at Nikaido's clothes.

Nikaido was so willing, let Senga push and pull at him any way he wanted, and the submission made Senga want to be even rougher, make Nikaido moan even louder.

“You get off on this, don't you?” Senga asked when he lay panting next to Nikaido after one of the most intense orgasms he'd ever had.

“Obviously?” Nikaido countered, back to his own personality as he smeared the sticky substance on his stomach with his fingers.

“No, I mean. On being dominated.” Senga continued, looking searchingly at Nikaido's face in case he'd try to deny it. But he didn't.

“Yes. By you.” Nikaido answered, turning to look at Senga with eyes dark as the night, and it made Senga's breath hitch. “It's not like I'd trust anyone to do it.”

That was all it took. Nothing changed between them during the day, they went back to their normal easy-going best friend relationship, but at night, Senga would make Nikaido do anything he could think of on a whim, tied him up, blindfolded him and whispered filthy things in his ear.

Back then, he had no idea he could be like that, but Nikaido always brought out new sides of him since the day they met.

Senga looks down at Nikaido, who's on his hands and knees on the floor with a dark leather collar around his neck, naked and aroused, and he can't help but smile at the thought that no one but Senga gets to see this.

Senga tugs at the chain attached to the collar, making Nikaido tilt his head up involuntarily, and his eyes doesn't widen in shock like that first time Senga pulled at his necklace, but the gasp is the same. “Tell me you're only mine.”

“I'm only yours.” Nikaido repeats, and the way he looks into Senga's eyes as he does clearly says that the words go deeper than this game they play.
