A bull/slave relationship is a twist on the traditional master/slave combination. It also typically involves cuckolding. In this type of arrangement, the husband is forced to watch as the bull dominates his wife. In most cases the husband is present, but in some arrangements the husband won’t be around. The husband can be straight or bi, as in many situations the husband acts as a fluffer for the bull. There are several different terms that are used in this arrangements. Here’s a quick overview so you can better understand.
Black Bull
This refers to a Caucasian couple who has chosen a black man to be the bull. Since it’s a common erotic fantasy for white women to take black lovers, and it’s not uncommon for white men to assume that black men are better endowed, this is the most common type of bull/slave relationship.
Working Bull
Another variation of the bull/slave relationship is the working bull. A working bull refers to a man that the cuckolding couple will see as inferior. Think of the pool boy, the cable guy, etc. This is a turn on for many because the inferior male takes control of the woman.
Ex-Bull
This isn’t as common as the above two, but it’s a variation that is seen often. Many husbands get off thinking about their wives with their exes. In most cases the ex-bull isn’t actually an ex, but roleplays one for the couple.
