How would hanzo and genji react if their s/o told them they thought it was sexy when they spoke to them in Japanese
;D Genji’s voice is like a kink for me so this is easy.
Genji would be flustered for a moment. It has been years since he’s received any attention like that considering the widespread hate for omnics currently. Then he’s remember his youth where he’d gotten that comment constantly and he gets a little boost in confidence with the knowledge that he hadn’t lost everything. He’d ask his s/o if they wanted to hear anything in particular and he’s make it a habit to speak Japanese whenever his s/o was around. He’d tease them with whispered words in their ear and saying things during battles. He’d even use it during intimate moments if he so inclined. He’d love every minute.
Hanzo would be taken aback due to never haven even heard of an accent kink before, let alone been told his was sexy. He’s probably flush and ask if they were being serious. When he had confirmation he would take the information and store it. He’s research the idea and slowly apply to whenever he would see his s/o. He’d start by simply saying hello in Japanese, before using terms of endearment and then using full blown sentences. It would escalate until his s/o would figure out what he was doing. He’d ask if they wanted him to stop and if not then they better get used to it.
