My first thought: Kinky My second thought: Oh gods I will totally answer that!
Prompto – He would hide it pretty well – Because he doesn’t really like it when people ask his S/O about the bite marks – It could be uncomfortable to answer a question like this – So he would bite them where he knows the skin gets covered by clothing – Meaning their inner thighs, shoulderblade, maybe their lower back, buttock (only if he feels like it),
Noctis – Their shoulder – He likes their shoulders – Also doesn’t like when people can see the bite marks – He thinks it might look cool when he stands behind them and bites into their shoulder – No one tell him whether it does or not
Ignis – Neck, lips, upper arm – In the most sneakily way possible – He asks if he can feed off them – But doesn’t do it immediately – Like: He asked them five hours ago and just comes waddling in nibbling on their ear slowly moving his lips down their neck to find the perfect spot – Doesn’t really care if they get asked – But if they tell them not to make it obvious – He won’t
Gladio – He loves to hide them and to show them – It’s more his S/O’s choice – Loves to bite way down their neck – Almost the shoulder – Just as much as he loves their arms – And buttocks – He’s a dirty one
Ardyn – They don’t really have a choice – When he’s hungry, he’ll take what he wants – Loves to bite them in intimate moments – It thrills him even more – Inner thighs, really close to their sex – nibbling their ear – Teasing their lip before he punctures little holes in them with the tip of his teeth – Neck – Will pretend to kiss the back of their hand to yank their wrist closer
Ravus – Hides them – Really good – Their back, back of their thighs, maybe even their ankle – Unless he’s heated – He doesn’t really care then
