If there’s one thing Tobio dislikes about being an omega, it’s how picky he is and how much of a perfectionist he ends up becoming. In the days leading up to his heat cycle, Tobio ends up flitting around from place to place while being almost unbearably overbearing about everything everyone does.
In a way, Tobio’s natural parental instincts come out towards the entire Karasuno team—including their old third year members and sometimes even their coach and Takeda—because Tobio views them all as pack. As family.
He scents everyone in sight, and almost tries to scent all of their belongings. It’s not a possessive gesture like it is with his boyfriend (his mate, the inner omega in his mind purrs, but Tobio ignores it for now—he and Kei have yet to fully mate, and don’t plan to until they’re a bit older, if they can help themselves from doing so), but rather, something that calms Tobio’s nerves. When his pack smells like him, then Tobio is content. When his pack doesn’t smell like him, then he turns into a bit of an anxious mess.
Kei finds it endearing, as well as rather silly. Tobio is still the same throughout his pre-heat symptoms, yet he’s completely different at the same time. Tobio doesn’t let it affect the way he plays, which is the biggest factor for it all, but Ennoshita will still force him to take more breaks than he usually would, and Coach Ukai will make sure not to push him as hard as he usually does, if only to keep from accidentally triggering Tobio’s heat when he’s not ready for it yet. (Plus, being stuck in practice when he starts his heat would be something Tobio would loathe to deal with. He’s already done it once—and Kei knows he never wants to experience it again.)
Tobio’s home is a little lonely, Kei’s come to discover. His parents are busy bodies who work more than they live, and his older sister is already off to college. Tobio ends up being home alone the most out of both of them, though not really of his own choice—simply because he has to be. Kei comes over regularly to help remedy that, but especially when Tobio is in pre-heat.
Kei’s own heat doesn’t align with Tobio’s just yet, but he’s fine with that. He doesn’t need their heats to align for him to want to be with Tobio during his. They’re dating, after all, and Tobio’s well-being means a lot to him—even if it had taken him well over a year to admit that to himself.
“Are you good?” Kei asks, carefully poking his head inside of Tobio’s nest.
It’s bigger than the one he made last time, taking up just under half the space of his entire room. Tobio is curled up against the back side of the nest, where it’s up against solid wall so it won’t fall over. He nods, though it’s a little jerky and Kei can see his brows are furrowed. The biological symptoms must be getting worse now, which means Tobio is probably going to enter his heat within a day or two.
“Do you want me to stay with you this time?” Kei asks, carefully entering the nest.
As soon as he does, Tobio is uncurling himself from the wall and reaching out to him in an almost pathetic seeming way. His face is scrunched up, obviously in pain, and Kei simply moves forward until Tobio can wrap his arms around Kei’s body and bury his face against his neck. He feels Tobio mouth at his scent gland, helping him release more of his scent into the air—lemon and ginger with the littlest hint of vanilla—which immediately helps Tobio’s body with relaxing.
Slowly, Tobio nods against his neck. Kei can feel him slumping into his body fully, giving way to some of the omegan biology within him. Kei reaches a hand up and sweeps his hand over slightly sweaty bangs, leaning down to press a kiss to Tobio’s forehead.
“Okay. Let me tell my mom and Akiteru,” Kei murmurs, shifting around a little to reach for his phone. “I’ll just have my brother drop off my stuff, so I won’t have to leave.”
Just the mere mention of the word ‘leave’ has Tobio tightening his arms on Kei’s body, tugging the other omega even closer to him. Kei can only chuckle as he texts both his mom and older brother about the situation; they’ll be more than alright with Kei spending Tobio’s heat with him, but he’s sure that his brother will tease him endlessly. (Not that he already doesn’t, but, still.)
“Kei.” Tobio mumbles his name a bit impatiently, meaning that Kei isn’t giving him enough attention.
He waits until he receives answers from both his mom and Akiteru before setting his phone down on the floor of the nest, a bit away from them and face-down so he won’t get distracted.
Kei leans down then, pressing a kiss to the side of Tobio’s head. “My brother will be here in two hours with my stuff.”
Tobio lets out a hum against his neck, pressing one last kiss to Kei’s scent gland. Pulling away, Tobio then leans up and presses his mouth to Kei’s in a kiss. It’s chaste and soft—Tobio isn’t chasing after anything quite yet—but Kei can feel the want and the need behind it, either way. Though they’ve only been dating for a couple of months now, Kei knows how to read Tobio almost better than he can read himself.
“Thanks,” Tobio mumbles against his lips, repeatedly pressing kisses into them. They go from fast and chaste, to slow and deep—a constant change of pace that leaves Kei feeling a little hot himself, only because Tobio won’t seem to let him rest a little.
He can’t help but be fond of the other omega right now. Kei’s heart always beats faster when Tobio is sincere like this, something he’s had to get used to being on the receiving end of since they started going out. Every little quirk of his is something that Kei adores, even if he does find some of them a little annoying. After all, they haven’t changed that much. Kei still loves to push Tobio’s buttons, and Tobio will push them right back—it’s a game, all to themselves, and Kei likes it that way.
“We’ve got two hours to make out before Akiteru gets here,” Kei says, running his hand down Tobio’s back. The other omega preens a little, arching into Kei as he presses himself closer.
The only over response Kei gets from him is Tobio curling his hands into his collar and pulling Kei down into the roughest kiss yet. Kei just hopes they won’t end up doing more than making out before his brother gets there, otherwise they might not stop.
