'Unbridled' in the Bible

And they, [the ungodly in their spiritual apathy], having become callous and unfeeling, have given themselves over [as prey] to unbridled sensuality, eagerly craving the practice of every kind of impurity [that their desires may demand].

But fornication and all uncleanness or unbridled lust, let it not be even named among you, as it becomes saints;

For this ye are well informed of, knowing that no fornicator, or unclean person, or person of unbridled lust, who is an idolater, has inheritance in the kingdom of the Christ and God.
