Chapter Text
The small, minor issue Iwaizumi has started off rather subtly, as a constant in their relationship, because Iwaizumi always wants to make Oikawa happy. He likes seeing Oikawa relaxed and peaceful when he’s in the bath, he likes seeing Oikawa beam as he scarfs down his favourite foods, he likes seeing Oikawa grin in satisfaction when he slams his crazy serve on the enemy court.
It naturally follows that he wants to make Oikawa happy in bed. He likes it when Oikawa moans in pleasure as Iwaizumi rocks into him, he likes it when Oikawa laughs in almost childish delight as he teases and edges him, he likes it when Oikawa flashes a smug grin as he tries out something new in the bedroom.
So Iwaizumi has a huge boner for making Oikawa happy. That’s not the issue. The issue is that now, he wants more - or well, less. Oikawa is a selfish, narcissistic piece of shit, but he’s at least considerate enough to take into account Iwaizumi’s pleasure during sex. The issue is that Iwaizumi kind of ... doesn’t want that.
Distantly, he wonders if there’s something wrong with him. It’s not that he doesn’t like coming, he does, it’s just not exactly his priority. If he comes during sex, he comes, but once Oikawa is finished, he doesn’t exactly want to burden his lover with it. Fuck, that reasoning sounds stupid even in his head.
Maybe he shouldn’t try to justify it to himself and accept it as it is. Oikawa ignoring his pleasure and just using him for his own gratification is exactly what gets him hot and bothered.
Sometimes, after many rounds of sex, Oikawa gets too tired to carry through with his usual diligence, leaving Iwaizumi hard and horny. Whenever that happens, he feels a rush of excitement as he cleans them up in preparation for bed. He could get himself off at any time, but instead, he always chooses to hide his raging boner and goes to sleep without finishing.
He considers telling Oikawa. Communication is key in a relationship. Between their two-decade-long acquaintance and Oikawa’s terrifying perceptiveness, it should be harder to hide something than to say it.
He tries to bring it up a few times, starting with a “You know you don’t have to make me come during sex right?” Oikawa predictably gets offended with a “How selfish do you think I am, Iwa-chan! Of course, I’m going to make sure you come, how badly do you think of me!” Oikawa talks over any further explanation and honestly, Iwaizumi isn’t bothered enough about this to turn it into a serious conversation.
A part of him hopes that if he ignores this kink of his, it’ll just go away on its own. He doesn’t understand his newfound desires, and he isn’t sure he wants to.
Another part of him is curious, and that’s enough for him to delve into articles and blogs and videos and oh god, he kinda gets it now and yeah, his fantasies are definitely not going anywhere.
He imagines himself on his knees, hands crossed behind his back, Oikawa’s grip firm in his hair, as he warms Oikawa’s cock in his mouth. He imagines himself bound to their bed spread-eagled as Oikawa pounds into him and he comes all over himself but Oikawa, he doesn’t care, doesn’t even pause as he continues his relentless assault even as Iwaizumi writhes in his bonds, oversensitive. He imagines himself looking at a blissed-out, well-fucked Oikawa lazily demanding to be cleaned up and carried to the bath, even as Iwaizumi’s own cock remains hard and erect.
He’s pretty sure Oikawa won’t mind indulging him in these scenes. They’ve certainly done wilder things before. In fact, he’d probably be delighted (and a little shit) about it. “Aww, Iwa-chan wants me to fuck him!” Ugh, why does he love that boy so much.
The issue here is that he doesn’t want Oikawa to indulge him. All these articles and blogs and videos have taught him another thing about himself, and it’s that he wants to do whatever Oikawa wants him to do.
And this whole kink thing is far, far more than just sex. Beyond the bedroom, Iwaizumi wants to serve Oikawa too, and honestly, he doesn’t know why it took him so long to figure it out.
Even back in high school, Iwaizumi took care of Oikawa. He did both their shares of setting up the court because Oikawa likes getting attention from his fangirls. He organised Oikawa’s room because Oikawa works better in a neat environment but is terrible at keeping things tidy. He woke Oikawa up before school. He carried Oikawa’s bag. He brought (and occasionally made) Oikawa’s bento. He bought food and drinks for Oikawa at his every whim. Looking back, he has basically waited Oikawa hand and foot his entire life. And he only wants to do more.
Upon this revelation, he promptly has an existential crisis because is this really his life, oh my god shittykawa is going to be such a smug asshole about this, jesus christ he wants to call his best friend Oikawa-sama god why and because Tooru likes subbing too what if he feels obligated to dom and because what if Tooru thinks he’s creepy and that it’s too much and also because what if this is just a really strange phase and he won’t be into it in a few months time then he has to explain this to Tooru and- okay, maybe he’s spiralling just a little bit.
Luckily, Sawamura is in town, so when an invite for drinks comes, he gladly accepts, grateful to relinquish the position of Responsible Parent to someone else for once.
“Iwaizumi, over here,” Sugawara called and waved him over to their booth, drinks in hand and a slight flush on his cheeks. (He was reintroduced to Sugawara, the so-called “Mister Refreshing”, at orientation in his first year of university, and got adopted as a friend because “hey! we miyagi-ers gotta stick together!”)
Kuroo, already a few shots in, leered, “Whassup Iwaizumi, it’s been a while since I saw you and your arms.” (Kuroo is Sugawara’s overachieving roommate, middle blocker and captain for his high-school national-level team, double major in communications and sports science, on a bonded scholarship from the JAAF to join the sports promotion division of the Japan Volleyball Association straight out of university)
Sawamura, long-suffering and unfortunately sober, scowled and slapped Kuroo over his head before welcoming Iwaizumi to the table. (Sawamura is Karasuno’s captain and Sugawara’s boyfriend. He drops by around twice a month from his police academy up in Tokyo.)
The four of them gel surprisingly well together, for a group formed based solely on their past commitment to volleyball, and consisting exclusively of varying levels of Parent Friends. Iwaizumi greets them each in turn before ordering a few drinks for himself. They exchange stories about the recent happenings in university and the next thing he knows, he’s groaning awake in a foreign bedroom.
Iwaizumi panics for a brief moment, because he has heard the various horror stories about drunken nights gone wrong. But his phone is with him, his clothes are all on, and he’s pretty sure this is Sugawara’s bedroom. Of course, that chivalrous fuck would give up his bed. He checks his phone, several missed calls from Oikawa, a lot of drunken texts, but nothing too incriminating of his current predicament, and one sober text sent from his phone, evidently written by Sawamura, confirming his safety and informing Oikawa that “Iwaizumi would be staying at Sugawara’s place for the night, we’ll remind him to call you back once he’s awake and sober”.
Memories from the past night come back in bits and pieces, and he recalls that all the group did was chat. God, he’s not even 21 and his fun outings are basically wine nights with the wives.
Then exactly what they had been talking about comes back and Iwaizumi abruptly realises that he has overshared way too much about his sex life. Mortification burns him up from his chest to the tip of his ears and he doesn’t want to leave the bed if he has to look Sawamura in the eye.
As it turns out, Sawamura doesn’t want to look him in the eye either, flushing red and averting his gaze when Iwaizumi eventually leaves the room.
Sugawara, on the other hand, has no such shame.
“Subby boy! How are you feeling?”
Iwaizumi spluttered, “Don’t call me that.”
“Are you going to do it?”
“What?”
“The plan, Iwaizumi-kun.”
“I think it’s a terrible idea,” Daichi cut in, “just talk to Oikawa-kun properly, I’m sure he’ll understand.”
Logically, Iwaizumi knew what Daichi said was reasonable.
Was he going to go through with the plan anyway?
Probably.
Going for a test run and indulging his kinks without committing sounded like a far better option for now.
So after the night out with drinks, a few traumatised friends and some dubious advice later, Iwaizumi settles into his new reality of wanting to serve Oikawa and decides on the questionable route of attempting to subtly integrate his kinks into his daily life without Oikawa’s knowledge.
