What if he instead grabs Azym's hair?

Then Azym will gently but firmly grab Zei's wrist and pull it away. "I'll do my thing and you do yours," he says. "Exposition time."

He grins and withdraws his hand. "Well I'm not sure what to exposition about!"

"Let's start with the thing you got interrupted from telling me about back at the village."

"...no, that is going to be a mood killer."

"...will it? Alright, then... Al Bhed? What's up with them?"

"Nnnope."

"Is there anything more you can tell me about this world that isn't depressing?"

"...I'm not sure?"

"Oh, fine, grab my hair, I'll suck you off for a bit and then we can get to the depressing stuff in the afterglow."

"I'm not sure, I don't know how into it I aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaam warn a guy before sticking a finger in his asshole!!!"

"Relax, focus on the sensation," he says, casually fingering Zei with one hand and jerking him off with the other. "I'm going to make you feel good."

"...alright." He doesn't grab Azym's hair but he does start running his fingers through it and try to focus on the sensation.

Good good. So if Azym is sufficiently persistent and good with his mouth and hand he can hopefully distract Zei.

...yeah. Yeah he can. After a few minutes Zei is starting to breathe heavily and cling to the bedsheets with one hand and Azym's hair with the other.

So it's probably time for more fingers, yes?

ngghhhhh yeah sure

Is it cheating to suck Zei off while finger-fucking him? Maybe, but Azym doesn't care, he's on a mission here.

Okay yeah sure he'll have a moaning whimpering Zei in his hands in short order, semi-unconsciously thrusting up into his mouth and clenching hard around his fingers.

But will Zei come.

Yes, yes he will.

Azym grins like the cat that got the canary, licking the remaining cum off his fingers while he watches Zei gasping like he just swam for half an hour straight without breaks, covering his eyes with the crook of his elbow. "Was I good?"

"Yevon you were, holy shit."

"Always glad to service."

"Come up here I need to kiss you."
