A cock whore is generally a submissive living the BDSM lifestyle. She or he, whatever the case may be, enjoy the sense of loss of self, or complete submission when they are made to give often very rough fellatio. The submissive is possibly bound, held by the hair, and forced to service. This is generally followed or preceded by cock worship, which is generally very tender and passive.
Are you my cock whore? You good little cock whore.
