Facesitting, also known as kinging or queening, is a sexual practice in which one partner sits on or over the other's face, typically to allow oral-genital or oral-anal contact, or to further ass worship or body worship. It is common for this position to form part of BDSM, involving dominance and submission, though this need not be the case.

Facesitting is most common among dominant women and submissive men, but also vice-versa, for demonstrating superiority and for sexual gratification. It is also practiced by vanilla sex couples for cunnilingus where the woman kneels over the man, and sits on his upper chest rather than face.

Unlike face sitting, in smothering the smothered partner is deprived of air.

The full-weight body-pressure, moisture, sex odors and darkness can be perceived as powerful sexual attractions or compulsions. The person sat upon may be in bondage, sexually submissive, or simply held down by the body-weight of the other person. Sometimes special furniture is used, such as a smotherbox or queening stool.
