SOUNDING
A sexual activity where a woman orally stimulates and teases a man's anus, often as foreplay or a form of intimate exploration, using her tongue and lips to bring pleasure and excitement to this under-explored erogenous zone. This sensual act is a symbol of trust, intimacy, and sexual adventurousness in both partners, blurring the lines between giving and receiving pleasure. The sensation can range from mildly ticklish to intensely pleasurable, and may be accompanied by other forms of affectionate contact or sensual exploration.
