Similar to the term used for a TV that is "cable-ready" or "HD- ready", "fellatio ready" is a term used to describe a girl who is so hot, she's ready to be orally sexed at any given moment.
STEVE: Hey Carl, did you see that hot waitress at Sonic last night?
CARL: Hell yes...that bitch was fellatio ready in those tight pants of hers.
