Oikawa & Kageyama bet one-shot (Haikyuu)
To most people passing by, the situation wouldn't seem too odd, the situation being Oikawa standing in front of Kageyama wearing a satisfied, victorious look, as Kageyama scowled and glared at him, a blush rising to his cheeks. Anyone who knew them would simply assume it was Oikawa's usual game of finding Kageyama to taunt him and, having won their most recent game, gloat about his victory.
To some extent, they would be right. Oikawa was here to gloat about his victory, but it wasn't just his victory in the game he was bragging about. After all, with the victory of the game came another victory, in winning the game he'd also won something else, a bet between him and Kageyama made the week before. When Oikawa had messaged Kageyama about the game the previous week, to taunt him obviously, not because he was excited to once again face his Kouhai. And even if he was excited, it was only because he'd get to beat Kageyama again, and had absolutely nothing to do with him wanting to see his Kouhai in general and absolutely nothing to do with the smug look Kageyama would give him when he managed to outsmart him on the court, not at all. So he'd messaged Kageyama just to taunt him, not at all using the game as an excuse. And he'd been every bit as provocative and mocking as he could, wanting to rile Kageyama up. It had worked, maybe a little too well.
When Kageyama suggested a bet, well, Oikawa did hesitate, but it was simply too good of an opportunity to pass up. He knew when he agreed what Kageyama would ask of him, the same thing he'd always wanted. If Kageyama won, Oikawa would finally teach him his serve. Yes, Kageyama had a damn good jump serve of his own, but the part of him, the tiniest little part mind you, that still admired Oikawa still wanted to know, still wanted to learn, still wanted to impress Oikawa. This inspired Oikawa. Since Tobio was asking for something he'd always wanted, it was only fair if Oikawa did the same. Ever since Kageyama first asked Oikawa to teach him his jump serve, there was one thing he'd always wanted to do. Back then, it had been more malicious, annoyance clouding his reasoning, and it only got worse as Kageyama became the tyrant king. But then Kageyama had improved, and Oikawa and Kageyama were on somewhat better terms, but that one thing still pestered Oikawa. It was no longer maliciousness, wanting to hurt, and embarrass Kageyama that drove this urge, this desire. He didn't know what it was. Maybe it was because Kageyama was still a bit of a brat, even if it was in a different way, maybe he just wanted to know how he'd react. The thing was, he couldn't, wouldn't, do this without context. Even though this was a bet, he'd still make sure Kageyama was actually okay with it before they agreed on anything. There was a discussion or two about it, but Kageyama agreed. If Oikawa won, he could spank Kageyama.
And Oikawa had won. He'd been teasing Kageyama about this since he'd agreed and now he'd won. Still, he didn't want to push Kageyama, so he gave him one last chance to back out before it began.
"You know, Tobio-chan, if you can't handle it, I can always change my bet to something else," he cooed in that same mocking tone but made sure Kageyama knew he mean it. If he was uncomfortable with it, he would change his bet.
Kageyama seemed to consider it for a few seconds, staring at the ground and scowling as he thought it over but ultimately grumbled, "I already agreed to the bet. Let's just get this over with."
Oikawa grinned, pleased. "Such attitude, Tobio-chan. Don't worry, I'll be sure to spank that bratty attitude out of you," he teased, winking at him playfully. "Now, first, let's get somewhere private. While I'm sure plenty of people would appreciate the sight of me spanking your butt, something tells me none of us would appreciate that getting out to the media." What he didn't say was that hopefully, after this, the urge to spank Tobio would be out of his system.
When they found a part of the stadium where no one would be, and after checking no people or cameras were around, Oikawa plopped down so he was sitting on the floor and patted his lap, "Over my knee Tobio-chan," he chirped cheerfully.
Kageyama grumbled but dropped to his knees and leaned forward so he was bent over Oikawa's knee. He tried to hide the fact he was blushing as he did so, though he was pretty sure it didn't work.
"There we go, that's a good boy, Tobio-chan." Oikawa declared as he wrapped his arm around Tobio's waist, pinning him down, and resting his hand on Tobio's butt. He noted Tobio's blush and grinned as he gave his butt a couple of light pats, just to taunt him and see him blush some more. "Comfy?" he teased.
"Just get this over with," Kageyama grumbled, scowling at the ground to hide how nervous and uncertain he was about this.
Oikawa narrowed his eyes at Tobio but then smirked as he lifted his hand and brought it back down for the first SLAP. He made sure it was firm enough to sting but not too harsh. This wasn't a punishment after all. Still, Oikawa said "Watch the tone, Tobio-chan. This is the last position you want to be mouthing off in.
Kageyama bit his lip to hold back the sound of surprise that nearly fell out at the first smack.
"Now let's see if we can turn the bratty king into a good boy," Oikawa declared before raining down a series of slaps, pretty much the same as the first one.
SMACK SMACK SMACK SMACK
Kageyama squirmed slightly under the slaps. They didn't hurt too much, just enough to sting but it caught Kageyama off guard and it took more effort than he expected to hold back the sounds he wanted to make. He knew that was what Oikawa wanted, he wouldn't give him the satisfaction, not when it had just started.
SMACK SMACK SMACK SMACK
Oikawa smiled to himself, knowing what Tobio was thinking as he continued spanking Tobio
SMACK SMACK SMACK SMACK
"You really thought your team could beat mine. Now look who's getting beat," Oikawa joked, giving a few harder smacks to emphasize his point before returning back to the firm but not really hard smacks. Kageyama let out a few grunts at the change but otherwise stayed quiet. That wouldn't do, it was no fun if Tobio didn't even react. Oikawa knew just what to do to change that. He gave Kageyama another round of spanks over his volleyball shorts before pulling them down to reveal his boxers.
SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK
"Wait," Kageyama tried to protest only to be cut off with a round of spanks, causing him to cry out and squirm. Oikawa wasn't spanking any harder than he was previously, but the loss of his shorts, and the fact that he'd already been spanked over his shorts meant he felt it a lot more. Kageyama tried to reach back to block the spanks, only for Oikawa to catch his wrist and pin it to his back.
SMACK SMACK SMACK SMACK
"Bad Tobio-chan, no reaching back. Did you really think your shorts would stay up? everyone knows bratty boys get spanked on their bare bottoms." Oikawa pointed out, as he covered Tobio's entire butt, except his sit spots, in a series of harder spanks, before returning to his default spanking strength. The harder spanks caused Tobio to yelp and kick his legs, making Oikawa smile. God, he should've done this years ago. The sight of Tobio yelping and kicking and squirming over his knee as Oikawa turned his butt pink and then red was one Oikawa was sure would stay with him forever.
SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK
"Bare?!" Kageyama demanded, shocked as he processed what Oikawa said.
SMACK SMACK SMACK SMACK
"Oh, you want it on the bare now? I was going to spank over your boxers a little longer first, but since you asked so nicely," Oikawa played oblivious as he finished the round of spanks and bared his bottom, ignoring Kageyama's protests and demands, or so it seemed, until he paused, resting his hand on Kageyama's bare butt.
SMACK SMACK SMACK SMACK
"Still being a bossy brat, Tobio-chan? That's okay, I know just how to deal with that." With that, Oikawa started spanking Tobio's sit spots, spanking a little lighter than before, not wanting to actually hurt him. Kageyama cried out, his pride long forgotten.
SMACK SMACK SMACK SMACK
"Are you sorry for being a bossy brat, Tobio-chan? Will you take the rest of this spanking like a good Kouhai?" Oikawa asked, teasing him slightly.
SMACK SMACK SMACK SMACK
"Yes, I'm sorry, I'll be good," Kageyama cried out, not even thinking about what he was saying.
SMACK SMACK SMACK SMACK
"Good, now let's finish this," Oikawa gave a few more rounds of spanks all over his butt, before stopping and letting him go.
SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK. SMACK SMACK SMACK SMACK
Kageyama jumped up out of his lap and rubbed his butt as Oikawa laughed. He wasn't at the point of sobbing but one or two tears had fallen out. As Kageyama calmed down and remembered what just happened, he couldn't help but blush in embarrassment.
"There, there, Tobio- chan, we're all done," Oikawa comforted mockingly before laughing again. Kageyama pulled his boxers and volleyball shorts back up before glaring at Oikawa.
"Hope you had fun because that's the first and last time you get to do that," Kageyama grumbled.
"I suppose we'll have to see about that," Oikawa muses. Turns out he was wrong. Spanking Tobio just once didn't get it out of his system. Oh well, he'll just have to find a way to do it again. Just to get it out of his system. Now, all he had to do was figure out how
