rimming

Rimming — also known as anilingus or "giving a rimjob" — is a form of oral-anal sex where the anus is stimulated by the mouth, particularly involving the tongue.

Tagging Notes

If a character is being anally stimulated by their own mouth, use autorimming instead.
Unless there's a strong implication of rimming occurring, if the character is merely being sat on and the rimming is entirely obscured, with no reactions, sound effects or symbols to indicate rimming, use facesitting or stinkface instead.
Posts featuring rimming should not be tagged with tongue penetration unless the tongue is shown penetrating the anus.
