Jungkook seems like he’d put up a bit of a fight. He’d wear the ears but it’d take a while for you to talk him into wearing the underwear. Once you did, he’d probably walk around covering his man nips telling you to stop looking at them and calling you a ert lol. He wouldn’t call you master though, I don’t have a reason behind it but I just feel like he wouldn’t. Sort of like a rebellion for him having to wear the kitty ears and underwear, so to speak lol.
