That—stops him.

"And, and, fine, maybe you can manage it on your own, but in the meantime you're just making every alpha around you have to be constantly fighting themselves for every scrap of sanity."

Aaaand he's angry again.

"I don't give a shit about dickhead alphas having trouble, you all deserve it."

...

He's not getting through to this guy, is he.

Fine, let's speak his language. Fighting spirit.

Tōkan pushes himself up to his feet, trying to control the wobble in his balance. Hiding his massive erection is a hopeless endeavour and it's making him real uncomfortable to be around an omega like that. "Look. You wanna fight? Fine, I'll fight you—"

"Finally—"

"Another day. Unless you want an unfair fight with me unable to defend myself because I'm using every nerve in my body to try to control myself," or an unfair fight in which he's not even trying to hold himself back and is going all in to stick his cock into every orifice on this guy, "you're gonna have to wait 'til your heat's done. I can't compete with you while I'm like this."

"Fine. But once I'm not in heat I'm going to fucking kill you."

"Looking forward to it. Now leave."

Inori flips him the bird then stalks away. He needs to find a new lead pipe anyway.

Once Inori is safely away Tōkan turns around to rest his forehead on the wall and try to get a hold of himself. That was way too close, way too many times. He's usually very good at self-control, especially compared to other alphas, and even he was having trouble there.

Also his cock's throbbing and he's knotting, this is the first time he's ever knotted without being inside someone or having someone inside him or at the very least simulating it well enough. That omega's a menace to society.

...cute though. And there's still a part of him that's mesmerised by the image of shutting the mouthy boy up with his dick, getting him to go from fighty and angry to moaning his name and incoherent noises coming out of his mouth.

Tōkan swore to himself he was never going to have sex with an omega but he never said anything about fantasising, and he's clearly not getting better right now. If this is what a rut feels like, it's not as bad as he'd expected; at least he was not completely overridden by instinct like some people say. But it does mean he's either going to need to wait several hours to calm down—which is medically dangerous—or he needs to take care of his business right now.

He chooses the latter. At the level of horny he is even the simple stimulation of pulling his dick out of his pants is strong enough to make him sweat and groan, and it's all downhill from there. He lets himself go, picturing that boy's face and a very flowery image of what his body must be like in his mind, thinking about how much he'd beg, how much Inori would cry for his cock, ask to be railed again and again, how hard it would be for Tōkan to even get in when he's already knotted, he bets that would hurt a lot and Inori would love every second of it, every minute of being stretched wide and open and vulnerable and used...

There's an actual puddle of cum on the ground and streams of it sliding down the wall when Tōkan's knot finally starts to subside after coming five times in a row. He uses a thumb to clean up the last dribbles of it coming out of his shaft and licks it clean (Inori would make such sexy noises with Tōkan's mouth around his cock, Tōkan's tongue exploring his pussy, Tōkan's lips all over him...) before zipping back up and coming back to the world. He needs to find his way home.

"Damnit Inori!" yells his omega dad. "You're in very bad heat! You can't just walk around all alone at night like this! And I told you already to get rid of that pipe."

"Pipe's new."

"Just stay home if you hate the medicine so much 😭," pleads his alpha dad. "Today's was really bad, I told you this morning—"

Inori ignores that and ruffles his kid sister's hair on his way upstairs. "I'm gonna crash. Don't need food."

"Yamada Inori are you even listening—"

No he's not, especially not as he shuts his door behind him and locks it...

...then falls to the floor, panting. "Fuck," he breathes to himself, and starts undoing his belt. "Every time, every fucking time—"

Inori notices something in his pocket while doing that and stares at it in confusion when he grabs it for a few seconds before remembering that's the bag that alpha gave him.

...

He lifts it up to his face and takes a deep, shuddering breath. He didn't think it was possible for him to get any harder but apparently he was wrong. He doesn't even finish undoing his pants before he's got two fingers in his pussy and is rubbing against that spot right under the bottom of his dick inside his vagina. His mask is still on and he's running purely on instinct now, the alpha's scent all over that little cloth bag, trying to pretend his fingers are much bigger and thicker, trying to pretend they're his cock—

It's picturing his face that tips Inori over the edge and makes him come and come and come and that's disgusting and confusing and he's still hard.

He hates being in heat so much.

"You really didn't fuck him?"

"Fuck you, Subaru, I've told you a million times already, I don't fuck omegas."

"It's one thing to say that, it's another to get hit in the face by those pheromones and run off with him..."

Tōkan peers at his friend from the corner of his eyes. "...are you jealous, Subaru?" And the light flush on Subaru's face is enough to confirm it. "You've never been jealous before. Just 'cause he's an omega?"

"Yes because he's an omega," Subaru grumbles in an annoyed tone. "You can fuck other alphas and betas all you want, but they don't have mind-control drugs pouring out of every pore."

"Well clearly I can resist his mind-control drugs just fine." Kind of. He didn't share the details. And he immediately got the strongest tolerants the pharmacy had available just in case. He never thought pheromones could get that bad.
