Since this has been asked a bunch: I like to think that the characters I draw in more "horny/fetishy" situations (like this one) are fairly clearly telegraphed as adults. IDK exact ages, it's a commission. Not my character.
But if the age is ambiguous to you, I don't feel comfortable gifting a plausible deniability, "they are 18+, go nuts!" answer. Please make your own conclusions/choices based on what you see.
