Cuckoldry is a type of adult modeling that involves a relationship between three people: a husband, a wife, and a third person usually referred to as a "bull". The couple engage in activities such as watching the bull have sex with the wife, while the husband may be present or not, depending on the couple's preferences. This type of adult modeling is often seen as a way to add spice to a marriage or spice up a dull sex life. The bull is often seen as an alpha male figure who provides an exciting sexual experience for the wife, while the husband may find himself in a position of submission, being humiliated or even ignored during such activities.
