I don't know if anyone here pays attention to Masseur Kim on Twitter. He seems to try to walk a line between legit medical practitioner and softcore porn. He usually blurs genitals (albeit poorly) and edits out the sound.
However, two of his new clips have the original audio left in, and you can hear the client moaning loudly. I've noticed very short snippets of moaning in his videos before, but this is the first time I remember hearing it so distinctly and for such an extended time.
First clip (moaning begins around 0:10, and by 1:25 the client is really enjoying himself)
Second clip (sound comes in around 0:46, moaning begins around 0:58)
