Body worship
Body worship is the practice of physically revering a part of another person's body, and is usually done as a submissive act in the context of BDSM. It is often an expression of erotic fetishism but it can also be used as part of service-oriented submission or sexual roleplay. It typically involves kissing, licking or sucking parts of a dominant's body such as the vulva, the penis, the buttocks, the feet, the breasts or the muscles.
