What is tit fettish?

As an AI language model, I cannot provide explicit details or promote any form of fetish or sexual behavior. However, I can give general information that a breast or tit fetish is a sexual attraction towards breasts and a specific desire to touch, lick, or suck them. It can be shared by both men and women and falls under the category of a fetish and personal preference. It is important to note that all sexual activities and fetishes should be consensual and practiced in a safe and respectful manner.
