Cock stuffing, as a porn video tag, refers to a specific sexual act or genre in adult content. In this act, one partner inserts their penis into another partner's anus or vagina until it is fully engulfed, often leading to a deep and intense sensation for both partners involved. This can be performed using various positions, techniques, or toys to enhance the experience.
The term "cock stuffing" primarily focuses on the act of inserting the penis (also known as cock) into another orifice, rather than the overall context of the sexual encounter. It's a popular category in adult films and is particularly appreciated by those who enjoy intense penetration scenes.
