Breast torture or tit torture is a BDSM sexual activity involving application of pain or constriction to the breasts.
Nipples are the easiest and most common target, being inflicted with pain typically by applying nipple clamps, a sex toy attached to an erect nipple to pinch and restrict blood flow by applying pressure and, when removed, causing further pain by the return of normal blood flow. Men's as well as women's nipples of can receive such treatment.
Erotic electrostimulation of the breasts is also practiced although such activity around the chest area may carry risks of electrocution.
In women, the entire breasts also can be involved with such painful activities as wax play, spanking, squeezing, or flogging.
The recipient of such activities may receive direct physical pleasure via masochism, or emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant.
Note that many of these practices, as with pussy torture for women and cock and ball torture for men, carry health risks. Adequate precaution is needed to prevent trauma or loss of blood flow.
