"Making... yourself... choke?"

“...want me to show you?”

"Not really! I don't want you to hurt yourself!"

Snort.

“That doesn’t even count.”

"It is kind of disturbing that you don't think choking yourself counts as hurting yourself!"

If Z consults Kaleva's body language rather than his words to find out what Kaleva is into, he will find that Kaleva is once again gripping the chair white-knuckled and also hard as steel.

“Shut up and watch.”

He returns his mouth to Kaleva’s cock, and this time he pushes his head as far down as he can, trying to fight his gag reflex and mostly succeeding.

Kaleva makes a strangled half-yell. His hands tangle in Z's hair and unconsciously pull hard enough to hurt.

Oh, that’s a way to get him to moan. And subsequently to choke, and try to pull back against Kaleva’s grip.

What if instead of pulling back Z stays exactly where he is and Kaleva sort of half-fucks his face?

Oh fuck okay that can be how this works instead.

Then he will just cough and choke and moan helplessly and try to keep sucking while Kaleva bruises his throat and he jerks his own cock.

Kaleva literally just had an orgasm so this is maybe going to take a while.

On the other hand, someone is choking on and moaning around his cock, and Kaleva is pretty damn sexually frustrated. 

The stream of praise hasn't stopped but it has mostly become a bunch of pleasant adjectives. "Good-- ooooh-- want-- yes-- need-- please-- handsome-- pretty-- good."

Somehow, being facefucked in the blacksmithing shop of Auradon prep by a painfully inexperienced mainland kid who’s complimenting him the whole time is managing to be the hottest thing that’s ever happened to him.

He knows that if he comes too early this is going to be worse for him — from a good amount of experience with the matter — so when he feels himself on the edge he stops, painful as that is, musters up the willpower to wait until he’s not about to tip over to start again, repeats. The moaning takes on a significantly more desperate tone.

Wow, desperate moaning. Desperate moaning is extremely great.

Kaleva notices that Z is trying to stop himself from coming, because all three of his functional brain cells are focused on Z. He stutters out, with difficulty, "you ca-- can come if y-- you want to-- aaaaaaa-- I don't miiiiiIIIIIII--" It trails off into a high whine.

—well, he can’t exactly explain himself—and he really, really wants to come, against his better judgement—

So he does, in the palm of his other hand, shuddering and whimpering and still trying to get air and keep from gagging so hard he ruins the whole thing.

Kaleva is watching Z very intently as he comes and when Z whimpers Kaleva bites his lip and says "fuck" and comes down Z's throat.

He tries to swallow, a few times, and then realizes that it is absolutely imperative that he come up for air right the fuck now.

He yanks with the hand that’s not currently a mess at one of Kaleva’s wrists, whining.

Kaleva lets him go.

He pulls back and gasps for air, coughing into his hand.

He’s a complete mess, hair mussed and tear tracks down his cheeks and spit dripping down his chin.

"You're so beautiful," Kaleva says with a tone of wonder.

“Tha—”

Never mind. More coughing.

“‘S not even true,” he says, hoarsely, once he’s recovered.

"I'm sorry! Did I hurt you?"

He shrugs.

"I'm really really sorry-- what can I do--"

“—I’m maybe gonna have a sore throat for a minute, it’s not a big deal. I do worse stuff to myself all the time.”

He looks totally bewildered.

"That doesn't actually make me feel better!!! I don't want you to get hurt!"
