Sleeping arrangements, unlike seats in the car, were fairly static. Ignis and Gladiolus usually slept next to each other, and Noctis next to Prompto. Ignis had said something about him and Gladio being his first line of defense, but Noctis thought it had more to do with the fact that Gladio was a cuddler and Ignis was the only one who didn't seem to mind. Not that Noctis was complaining, he had no idea how Ignis managed to sleep every night with that buzz saw right in his ear.
Noctis had his own issues with the arrangements. At first it had seemed fine, Prompto had stayed over a bunch in school, so they were used to each other. Occasionally he'd catch Prompto talking in his sleep, muttering to himself about this or that before rolling over and going quiet. He had no idea he even did it either, the once or twice Noctis had brought it up Prompto just laughed, "Really, what about?"
Something about this road trip turned quest to destroy the Empire, however, seemed to bring it out way more.
Sometimes Prompto would whimper and toss his head from side to side, quietly whispering to himself, "I'm sorry, I'm sorry. I didn't mean to lie." Pleading with whoever he was dreaming about. At times like that Noctis found that it helped if he held Prompto close and whispered back, "It's okay," until he calmed down, then he could roll over and get back to sleep.
Sometimes it was downright terrifying. More than once Prompto had sat upright and stared at the door of the tent or the hotel room, "The deamons are here." or "He's coming." Then he'd just lay back down like nothing happened.
Other times he'd smile to himself, hugging his pillow tightly muttering about chocobos. Mostly it was almost endearing, but it got annoying when he'd sing in his sleep "I want to ride my chocobo all day." Noct did not want to admit how many times he'd woken up with that stupid song stuck in his head.
There was the usual stuff too, like "let me get a picture of this" or "great shot, love the lighting". He'd compliment Ignis's cooking or laugh and tell Gladio not to be mad. There was a lot of incomprehensible muttering, and sentences that didn't make sense like "use the noodles, deamons hate noodles" and one time "of course my camera can fly, does it look cheap?"
The roughest nights though, were ones like tonight. Noctis was trapped with Prompto's head on his arm, one of his legs tossed over Noctis's, and a hand on his stomach. At some point he'd managed to get under the hem of his shirt, fingers splayed out over Noctis's abdomen. When this happened Noctis just couldn't get back to sleep, and if he tried to pull away Prompto would move closer, a real no-win situation.
It was like he was afraid to breathe, that it might wake Prompto up, and that would be awkward. Awkward because of the position, but more so because the gentle breaths against his neck and the hand under his shirt had given him a hard on. Try as he might to tell himself that it was just morning wood, Noctis couldn't quite get himself to believe it, and if he couldn't convince himself how was he supposed to convince anyone else?
His breath hitched as Prompto scooched closer, the calloused hand under his shirt rubbing gently back and forth and giving him goosebumps. "Mmm, Noct." Prompto muttered into his ear, causing Noctis to bite his lip to muffle the sound of his too ragged breathing.
Prompto laughed gently in his sleep, and Noctis swallowed around a lump in his throat. "Noct… you've put on some weight."
In a swift, fluid motion Noctis shoved Prompto to the other side of the tent and rolled over, pulling the blankets over his head. Behind him he could feel Prompto shift around half awake,then roll over and fall back asleep.
Noct was the first one up the next morning.
