cw : A/B/O , nsfw , intersex omega

Whenever Mirio lost his clothes in class, he used to feel all embarrassed and troubled. Ever since he presented as an omega, however, he also ends up soaking wet. The air and exposure are bad enough, but his classmates' looks on him just+

add up to it. He's taken to wearing slick pads, but those stay on his clothes when he loses them, and everyone can feel the smell of his slick as clear as day every time he ends up naked. It's mortifying to no end, and the source of a lot of unwanted attention.

And then there are the times where he forgets his slick pad in the morning. If he puts on his uniform like that, it'd just reek of slick the whole day. Logically, Mirio knows he should probably borrow a pad fron a fellow omega, no judgement implied. And he /could/- but+

it's just funnier to call Tamaki.

Whenever he does, Tamaki comes immediately. His alpha hates the idea of other people looking at him but, more than anything, he hates the idea of Mirio being uncomfortable. He always has. That's how he started to use this "solution."

Mirio drowns another scream on his hand as Tamaki's tongue licks at the base of his cock. Fuck. Tamaki is so /good/ at this. So freaking good. Every movement sends more sparks all over Mirio's body, he can feel his face burning, his legs so wobbly he just has to+

get ahold of something (anything) to steady himself. It's how his hand ends up in Tamaki's hair, pulling at his boyfriend's dark strands whenever everything becomes /too much/. Tamaki moans when he pulls, and the sound alone would be enough to send sparks of pleasure+

through Mirio's body, but the vibrations around his cock are too much. He bites his lips, shivering and panting and begging for more, even though he can't think of anything else to ask — this is so much, too much-

Mirio keeps his eyes closed, because Tamaki made him promise he wouldn't look, but it's so tempting to just take a peek — to see his alpha all red-faced but firm and determined. People can say whatever they want about Tamaki, but there's no stopping him once he sets+

his mind on a goal. Right now, his goal is to make Mirio come.

And he's close. So close.

"T-Tamaki- T- /ah/ /Tamaki/-"

Instead of pulling away, Tamaki swallows around his cock, his hands firm on Mirio's hips. Mirio feels something — something soft and long and textured+

entering him. He cries out and comes /hard/. His legs shaking so badly he would have fallen, weren't Tamaki's hands holding him in place.

Mirio can hear Tamaki pull away, his cock abandoning the wet heat of Tamaki's mouth with an obscene pop. He can hear him /swallow/ and+

pant again, the heat of his labored breath making him shiver again.

Tamaki is not done yet, though. A perfectionist to the bone, his boyfriend now licks all the slick off Mirio's skin. He starts with his thick thighs, making his way up and up until he /finally/ gets to+

Mirio's swollen red cunt. He flattens his tongue, then, and Mirio has the wherewithall to notice it's wider than normal- but wondering what Tamaki could be manifesting is nowhere near enough to grab his attention when Tamaki is licking his labia like an ice cream, making+

obscene /pleased/ sounds as he swallows. It's so hot it almost gets Mirio going again — /almost/. He's way too spent.

Tamaki doesn't stop until Mirio's hole is red and swollen, but slick-free.

Mirio can feel bruises on his hips, right there where Tamaki's hands were holding+

him, and he entertains the idea of just leaving them there for his next class training. Then /maybe/ he wouldn't get as many looks- it's annoying, but a bunch of people will answer better to a mark like this. It means Mirio is owned — that if they want to have anything+

to do with him, they'll have to go through Tamaki first.

The thought makes him smile.

Mirio lets himself slide until he's sitting on the floor, cold tiles unpleasant against his burning red skin. He feels himself shiver just once, and then Tamaki is handing+

him his underwear.

Mirio pulls him closer when he does. He hides his face on his alpha's shoulder and /breathes/. The scent of his alpha's arousal almost threatening to make him hot and bothered again. He wants Tamaki's cock — there's nothing better than feeling+

him opening him /just right/... But Tamaki doesn't want to knot him at school. this will have to be enough.

He purrs on Tamaki's shoulder, sighing softly. He doesn't have to look to know Tamaki is probably red-faced as he brings him closer, pressing his arms around+

Mirio's body.

"Do you want me to-?"

"/Mirio-/"

"I know, I know. Not at school. Fine."

(It's not like he begs for his knot /every/ time he sucks him off. Sure, it happened last time, but it was just once! Mirio can be good if he tries.

Maybe.)

They stay there for a while, listening to each other's breath until Mirio moves. He runs his hand over Tamaki's hair, opening his eyes.

As always, the well-lit school bathroom takes him off-guard. He chuckles imagining the scolding they'd get from the school staff if they knew+

what they do on their breaks.

"Come to my house after school," Mirio says, breathing slowly, "my dad isn't home."

He hears Tamaki's breath hitch, and has to suppress a smile. /How is he so adorable-/

"O-okay."

"Tamaki?"

"Hm?"

"Thanks."

"Y-you're welcome-"
