In the context of a "live fuck machine used to please as the femdom directs" I don't think a bull is the correct term. A Bull doesn't take direction, it does its own thing it can only be controlled by a nose ring. What your thinking of is more like a boy toy, a fuck toy, even a tool.

A bull. Now your bull is usually dominant but a good partner will let ya get your kinks out.
