i'm so sorry i fell asleep the other day and forgot that i was going to answer questions 😭 but this is kind of a tough one believe it or not because i feel like if i'm writing something i can kind of wrangle them into any kink i want, BUT they're both really curious and adventurous people so i think they'd be into trying a lot of stuff, law would jsut be the one who had to point out the potential issues and reasons they might NOT want to do something but in the end luffy can talk/fuck him into just about anything. it might as well be canon that law has a big sadomasochistic streak and he and luffy can both handle a LOT so all sorts of pain play are on the table, and medical kink including vivisection 😈 and not gonna lie, with the gloves and everything i think it'd be extremely funny for a rubber man to have a latex fetish lmao.
size difference for sure, mostly on law's part, especially now that g5 sex is a possibility, uhhhh breeding, cockwarming...i'm definitely rambling and forgetting things but if i don't stop i'm gonna be here all night
