A submissive, usually a cuckolded male, who performs oral sex on a dominant woman, prior to her having sex with another man, in order to make her sufficiently aroused and lubricated for sexual intercourse.
Mistress Julie's houseboy also doubled as her pussy fluffer. He would clean her luxurious apartment prior to her dates, and then ready his owner for sex with a well-hung bull by going down on her. The bull would take it from there. Sometimes the houseboy would watch his owner get pound fucked, while other times Mistress would send him out of the room.
