Summary
It’s not like Oikawa is scared of thunder or anything. He’s seven years old now, and seven year olds aren’t scared of something stupid like that.
(The way he practically jumps out of his tangled mess of blankets at the next loud clap of thunder and his racing heart don’t count as being scared. No, not at all. Definitely not.)

This entire situation would be better if he didn't have shitty coffee.

Summary
The seat creaks unpleasantly when the brunet flops onto the worn cushion, stretching his arms high above his head. Maybe a moment too late to be considered perfectly polite, he turns and asks: "Hey, can I sit here or will your imaginary friend get mad at me?"
Or, Aone meets a talkative stranger on the train.

Summary
He sighed, kissing Oikawa's shoulder, and enjoying the silence. The wedding rush of the past few months was exhausting, and once the adrenaline wore off, his muscles were strained from all the effort. Still, all the tiredness had been worth it, and Iwaizumi could even bleed his heart out if it meant he could meet Oikawa at the altar once again.
Iwaizumi and Oikawa enjoy their honeymoon.

Summary
“Do I have to do this every time? Fuck you until you’re too tired to do anything else? Is that what you want? To be fucked stupid every day until you learn how to take a break?” The question must be rhetorical because Iwaizumi adjusts his grip on Oikawa’s thighs, using his elbow to press into the dip of Oikawa’s knee, then pushes his fingers into Oikawa’s slack mouth. Oikawa’s other leg stays where it is, like his body knows on an innate level to stay open for Iwaizumi.

Hesitant, almost.

Summary
“I was going to talk to you about it. Didn’t you notice Oikawa and Iwaizumi-san are acting differently with each other?”
Yahaba thought about it for a second, before saying. “I don’t think so?”
Kindaichi scoffed. “You, the biggest Oikawa supporter, didn't notice? I’m surprised.”
“Fuck you, Kindaichi, just get to the point!”
“Don’t you think they’re a lot more distant than they were before?” Kindaichi asked. “Normally, they bicker and tease each other all the time. Now… it’s like they barely talk.”
Yahaba looked up to where Oikawa and Iwaizumi were standing. “Now that you’ve said it, I can see what you mean.”After losing at the Interhigh Prelims, Kindaichi noticed something changed between Oikawa and Iwaizumi. Now, more determined (and distressed) than ever, he and Yahaba want to discover what is wrong, and find a way to fix it fast.

Summary
“Hajime–” Oikawa reached out a hand, his scent washing over Iwaizumi.
Once more, anger flared, and with it, adrenaline. Iwaizumi bit out a growl. He wanted to pin Oikawa to the ground. He wanted to sink his teeth into his neck. He wanted to hold on tight until Oikawa’s scent died out and all that was left was a whisper of it floating in the air.
No. No, he didn’t. Iwaizumi blinked, and something akin to a whimper left his tongue.
Before Oikawa could say anything, he bolted.
The Seijou Pack has just defeated Inarizaki in a long, drawn out war. Everything should be peaceful and relaxed. But when the next full moon comes around, Iwaizumi is anything but. He's unable to control himself, his wolf, and Oikawa's Alpha scent only makes Iwaizumi want to hurt him.

Summary
Clearly Iwaizumi had a checkered past. Kyoutani has never asked about it, nor has Iwaizumi ever brought it up. He knows it’s a sore spot for his mentor, just like the gorgeous Monte Carlo he keeps hidden away is, so he leaves it alone. Out on the streets, you learn a little something about when to turn a blind eye in order to survive; Kyoutani knows better than most to leave the past of men like Iwaizumi well alone.
It’s probably got something to do with the boy in the polaroids, though.
Retired pickpocket & conman Iwaizumi Hajime receives an invitation he can't possibly decline, pulling him back into his old life to work a job with his old friends and ex-lover Oikawa Tooru. His mostly-legit apprentice Kyoutani gets dragged along for the ride. It's a complete mess.Series

Summary
Matsukawa is quick to test his limits, thrusting as deep as he can and staying until Oikawa’s throat is spasming around him, until his eyes burn with tears that soak through the blindfold, until drool dribbles along the corners of his mouth. He pulls out and Oikawa hangs his head, a slick mix of saliva and precome trickling past his gaping lips. Matsukawa’s long fingers tip his head up, thumb slipping into his mouth and swirling the mess he’d left behind.
“If only you could see yourself.” Matsukawa growls, voice deep and fringed with the roughness of arousal. “Such a wreck just from this?”

Summary
“Hm,” Oikawa pouted, his tongue still out in protest. “You take care of me, then, Mr. Soulmate Expert.”“I will,” Hajime’s words tumbled out before he could stop them. Tooru was caught off guard, and Hajime supposed he couldn't blame him. Here he was, a six year old promising to take care of another six year old. It was almost laughable.
But there was something different about Tooru that Hajime couldn’t push aside. There was something about him that made Hajime want to protect him from the world, for soulmates’ sake or not.
In a world where soulmates can feel each other's pain and injuries, Hajime vows to protect his other half, who may be closer to him than he knows.
Written for the 2021 Seijoh Exchange.

They don't know what time it is, but they couldn't care less. Iwaizumi's sleep schedule has been broken for weeks now, and the reason is right there under his body, flushed, panting and submissive.
His inner alpha couldn't be prouder.

Summary
“Iwa–chan.” Oikawa shuffled closer to Iwaizumi with an excited glint in his eyes. “Do you know about bitching?”
Iwaizumi’s anger was replaced by surprise, followed by mortification. A subtle blush appeared on his ears.
“Bitching…?” Iwaizumi muttered, unsure if he heard that right.
—
Oikawa desired to be an omega his whole life. When he presented as an alpha instead, his hopes were shattered and he felt like a stranger in his own body. After years of fighting his inner instincts, he was offered a solution to his problem. This was something he couldn’t start on his own however.
So what did Oikawa do? He asked his best friend for help, of course.
