Anyways this is my view of different Oscar kisses for different Oscar pairings:
Lando/Oscar - so much fucking giggling like OMG can they stop being so cute. A lot of simple little pecks but Oscar knows to pull Lando closer by his cheek to deepen the kiss when he wants to. I feel like Lando would kiss Oscar's nose a lot lol cos it makes Oscar wrinkle up his nose really cutely
Carlos/Oscar: pls it's not a real kiss for them if they don't use their tongue lol. Oscar likes to bite Carlos's tongue too if he is annoying, or just chomp down on that full lip<3 lots of hair pulling involved from both sides as well and it's just filthy and messy ksks. But also them calming and just barely keeping their lips touching as they catch their breath<3
Max/Oscar: so many little pecks, not just on lips but on cheeks, forehead, hands, inside of wrists, behind the ear, neck... just everywhere! Max knows EXACTLY where Oscar's freckles are cos he kisses all of them! But they defo like having Oscar in Max's lap for a deeper kiss that leaves them both blushing and nuzzling their noses together
Charles/Oscar: Charles is just pursing his lips at random points of the day to ask for a kiss and Osc will go RUNNING to kiss him!! Alwsys starts as light pecks but Osc wants those deep kisses, shyly deepens them and Charles might not exactly be French, but he definitely has a talent for French kissing!!
Mark/Oscar: oh Osc would be such a tease, pulling away from the kiss when Mark tries to deepen it and biting and licking at Mark's mouth when Mark goes too slow sksk. So many little noises and moans too, and a lot of grabbing at Mark wksk.
