Character Relationship: Male hooker and male client, but not sexual
Link: http://archiveofourown.org/works/714299

Limited aspect is the seasickness, but there is decent lead up with Jongin trying to not have it happen while he's being paid to be a gay hooker.  Not actual hooker action and not because vomiting kills mood, so kind of interesting plot in not as one would expect it to go.  Totally could imagine a good emetophile kinkier outcome, but alas it's not what it's even close to being about.
