Oral without condom to completion is generally used to describe the act of bringing a man to orgasm by performing oral sex on him (fellatio) without a condom. In this case, it is assumed the "oral" in question is fellatio and not cunnilingus due to the reference to a condom. For cunnilingus, a dental dam would be used instead.
