This is for my girlfriend, she’s a bit down and really likes Promptis, so I’m doing headcanons for it, just random stuff. @lencesfences
Prompto will sing at the top of his lungs if a really good song comes on the radio. He won’t let anyone turn it until it’s over, but if somehow Noctis changes it to the best of his of his ability; Promto will give him the silent treatment.
Prompto is incredibly clumsy wherever he goes, so when they get to a camp or a resting spot theres always band aids provided by Ignis. (Noctis has to help put them on.)
Prompto is as innocent as it can get, but he isn’t too innocent. Only Noctis can vouch for that though.
When Noctis is upset he’d rather be alone, but Prompto follows him to make sure he’s alright, and the end up talking about their lives together and how far they’ve come
Promptos scared of the dark at night when everyone’s in bed, and since Noctis and him share a bed since Ignis likes to save money, he holds his hand to reassure him that he’s alright.
After showers, Prompto just likes to get dressed and sleep, so Noctis helps him with his hair because Prompto won’t brush it.
Noctis has a lot of nightmares due to his powers and how much responsibility he has hanging on his shoulders, so Promptos always there to comfort him when he wakes up, giving him breakfast that was freshly made thanks to Ignis
Prompto is definitely a morning person, waking up and being energized solely on the fact he gets to see new things and be with his friends, so he’s normally up with Ignis, in which Noctis hates because his warmth just gets up and literally waltzes away
When Noctis and Prompto are in a relationship, Noctis is the one to say ‘I love you,’ the most. When he does, Prompto turns into a babbling flustered mess, and has to show that he loves Noctis back but in a different way, his words have literally left his head
Prompto easily gets cold, having no arms on his jacket, so Noctis lends him his over shirt so he can warm up
Noctis and Prompto play around a lot at camp, in which Gladio and Ignis have to tell them to be careful because they’re so close to the fire
Promptos made a small book of pictures he’s taken and a bunch of pages are dedicated to him and Noct together, that or just Noct
Promptos always constantly worrying about his friends, especially Noct, because of how reckless he can be sometimes, he always asks if he’s okay or if he needs something, and it makes Noctis laugh about how caring he is
Noctis is continuously pushing himself to the point he gets sick normally, so Prompto offers to take care of him, in which he brings him lots of soup and gives lots of hugs. He also shows him all the pictures he’s taken too, each one has a story behind it and it makes for good bedtime stories
Promptos extremely embarrassed with his body, which means normally when he completely takes off his shirt he feels like his guard is down and he’s going to be mocked by Noctis, but Noctis kisses his stretch marks and muscles and tells him he looks great
Noctis won’t admit it but he’s a pretty sentimental, romantic guy. Prompto won’t admit it either but he actually loves being swept off his feet and loves when Noct is all romance like, so much so he could swoon
Promptos favorite time is bubble baths. Noctis gladly joins him and they have bubble fights that end up leaving a mess
The two also have a lot of petty arguments over who’s cuter or who’s more hot, and it begins to turn physical with kissing and touching
They also can get jealous easy but won’t admit that, Noctis is normally the first to get jealous, and if he is he’ll do something to make Prompto jealous back. They eventually sneak off and get out their anger by holding hands and kissing like nerds
Prompto sometimes starts food fights with Noctis which ends up with the two having to shower and getting scolded by Ignis and Gladio
Prompto has constant nightmares about his past and being practically all alone again without any friends, so someone, such as Noct has to constantly remind him that he’s loved and needed
Noctis wakes up and quite often has to shave his facial hair. Even if Prompto does too, he teases him about being an old man and they bicker about it
Nowadays if the Regalia isn’t being used, the two will sneak off with her and drive around to talk and have alone time.
Gladio likes to now call it the love wagon, in which Ignis almost visibly is uncomfortable with.
Prompto tries to tease Noctis by now referring to him as ‘your highness’, but all it really does is somehow turn him on, and Noctis can’t stand it. Prompto finds it hilarious, nonetheless.
Prompto continues to slap Noctis’ ass to this day. Friendly or not, it’s still funny in his eyes and Noctis still doesn’t understand why he continues to do it
Noctis and Prompto will flirt with each other on quests, missions, and sometimes on the battle field. They flirt everywhere and Gladio has to somehow break it up before him and Ignis are victims to watching romance bud and break out right in front of their eyes
Noctis nonchalantly likes to call Prompto princess. Teasing him is something he loves to do, but he really sucks at it so much it can be cringey at times if he doesn’t do it right
On the other hand, Prompto is great at teasing and can easily fluster Noctis. But all Noctis has to do is come with a great come back and they’re both flustered with a bit of smugness.
They’re both really competitive with video games two. All relationship and relations are set aside when they play, and they show no mercy towards each other. They get so wrapped up in the game it breaks out in a small physical fight, that if isn’t broken up it could easily turn sexual.
The two normally don’t argue over serious issues. If Noctis is angry and he expresses that, normally Prompto will try to talk it out rather than argue against him, seeing as for real life, literal conflict with his partner isn’t exactly his thing, and he’d do everything in his power to try to avoid it
Noctis counts all of Promptos freckles when the two are cuddling in bed or having sex. He mostly gets sidetracked and tries to kiss the freckles all around Promptos body and it gets him flustered and embarrassed
Noctis enjoys star gazing too. Sometimes the both of them will be together, Promptos back pressed up against Noctis’ chest, and they’ll watch the stars together, and just tiredly speak about how much they love the other, that or sit in blissful silence.
Promptos incredibly scared of the dark though, so normally everywhere they go they have a nightlight to sooth him so he can sleep. If they don’t have that, he’ll cling to Noctis.
During sex, Prompto swears a lot, and only admittedly will swear the most in that time, preferring not to really swear anytime else, even if he lets some slip. Noctis enjoys hearing the bad language though
Only around Noct, does he swear like that and speak badly, but not over kill. Noctis can get flustered by it sometimes and Ignis and Gladio are oblivious to what Prompto says.
Noctis and Prompto have a lot of scars from fights they’ve had with monsters and such, so they normally kiss each others visible scars in the area their face is most close to, to reassure the other they still look great.
Noctis enjoys sex when he can see the others face. He likes to look at the others facial expressions and he also enjoys to listen to the others noises at its full maximum.
Prompto on the other hand, buries his face in Noctis, neck because of how embarrassed he can get when Noctis breaks out the pet name and the compliments.
The way to get Noctis to go harder and more extreme during sex is to call him your highness, or at least thats what Prompto does.
Prompto really really likes neck kissing and biting. He also likes the love marks and love bites Noctis leaves on him.
During sex Noctis will try to close the gap between them as much as possible. For him, closeness is the key. He loves to have great intimacy and great closeness
Prompto has such a high sex drive that he’s normally still riled up, while on the other hand Noctis is ready for bed
Embarrassingly enough, When Noctis demands things during sex, but not too pushy, Prompto loves it. Especially when he bosses him around.
And when Prompto refers to Noctis as King? He’s done for.
Noctis likes to rile Prompto up by subtly hinting towards things in conversation while the others around. That’s how he can tease him to get his revenge, and Prompto hates it.
Prompto and Cindy are best friends, in which Noctis can slightly disagree against liking that matter, being a bit more jealous than he’d like to admit.
