Who do you think in skz would be most likely to let you rim THEM? I think definitely Jisung and Hyunjin (although I’d like to think all of them would like it its one of my favorite things to do <3)
i'd like to think the same although i don't see everyone being into getting rimmed as much... but the ones i think would enjoy it the most are:
maybe surprising to some but i'd put minho first. not because he's the most likely to let you but it'd be an accidental discovery he turns out to be really into. he's either shameless or shy about it and he makes the prettiest, softest noises while you keep his legs spread. folding those pretty thighs open. his ears get so red too <33 and if he's in a more dominant mood he might order you to suck his balls and rim him until your jaw aches
hyunjin: face down, ass up. clawing at the sheets. biting his pillow so he doesn't cry too loud. secretly hoping you'll fuck a couple fingers into him while you're at it (all spit, no lube; he likes it when it stings a little). the type to twist his cock until it hurts while you fuck your tongue into his sensitive hole. goes crazy if you spit on it
jisung letting his freak flag fly and liking ass in all positions... he always insists on trying 69 but the sensations are too overwhelming, so he ends up riding your face instead. arches prettily while he grinds down, unable to keep his hands off your tits in front of him. he cums all over your chest (a lot) just from you licking and sucking on every inch of skin you can reach
honorary mention: chan & changbin, since i don't think they'd be in the mood for it often (they'd prefer to have you sit on their face instead), but they'd let you if you really want to. whatever makes you happy. and secretly they enjoy the attention and praise even if they're shy about it at first. you just can't help it. having all that ass? it's impossible to shut up about how pretty they look and how you need a mouthful <33
