At the beginning of their relationship, John is far too quiet in bed.
The man can talk; his mouth is filthy and blunt in a way that Nikolai enjoys, but John never moans or makes any actual noise to ensure Nik that he's enjoying himself.
Thus, the pilot approaches him with a plan in mind.
Sucking John's cock is something Nikolai loves doing. He likes getting wet, messy and loud about it. Trailing his tongue along the underside of the man's cock and sucking at the head as he strokes his hand over what isn't in his mouth.
He likes the deep furrow between John's brows as he stares at the ceiling, gaze far gone. He likes the way the man's thighs twitch, quivering as he digs his heels into the mattress. It's the only warning he gets that the lieutenant is going to cum before he shoots ropes into Nik's mouth, and he's left to swallow the mess.
Only, for once, he doesn't pull away. Not as John's cock begins to soften in his mouth or as the man's legs fall flat against the bed.
He bobs his head over the other man's spit-slickened cock and coaxes it back to hardness even as John sucks a breath through his teeth, abdominal muscles clenching as his foot jerks and catches Nikolai's thigh.
"Shit, I'm done. Nik, I'm done."
He keeps going even as he hears the hitched, gasping noises John makes as if every breath is being punched out of his chest. As the man's hands tremble, his fingers fight to curl against the hard mattress.
He keeps going as John's expression contorts through confusion, irritation and agonised pleasure. Hips spasming, fighting between bucking up into Nikolai's mouth and trying to pull away from the man entirely.
When the other man jolts, Nikolai plants his hands on his hips to still him and his futile efforts against the unrelenting pleasure he's being subjected to.
The shock almost stops Nikolai in his efforts, the whine in John's tone as his tears rim his eyes, and his thighs shudder by the Russian's head. Until he catches sight of John's hand, racked with tremors as he reaches out for Nikolai's hair, only to drop it back onto the mattress.
Then he doubles down on his efforts.
The second time John cums, the man convulses.
His back arches off of the bed, nostrils flaring as his limbs tense until Nikolai can make out every vein against his sweat-damp skin. John's nails pierce the pilot's shoulder as though he's gripping his only anchor, his orgasm pulled through his wailing pleas and shuddering, keening moans as he floods Nikolai's mouth. Only when he swallows around the lieutenant, do salty tears trail down the other man's cheeks.
When John's back hits the mattress, the man is panting like he ran a marathon, and he's flushed from the tips of his ears down to his chest.
His voice is ruined, and he looks the picture of fucked out, exactly how Nikolai wanted him.
It takes John a while to even register the statement, over his heart pounding in his ears and the black that had begun to overtake his vision. The laugh that breaks free from his chest is hoarse and bordering on hysterical.
"That's what that was for? Bloody hell, Nik. Just ask, you don't have to suck my soul out of my cock if you want to hear me."
Deep in the back of John's mind, he knows that it's fruitless. Now that Nikolai knows how far he can bend John without breaking him, he'll never relent.
John can't bring himself to care, not when his entire body is tingling.
