Breast bondage is a technique used in BDSM play. It differs from most bondage techniques in that it is not intended to restrict the mobility of the tied person directly. However, it can do so indirectly when it is combined with other techniques. Rope is usually used, due to its ease of use, but leather straps and even chains can also be used. A bondage harness can also be used to achieve the same effect as breast bondage.
Ropes are tied around the base of each breast, causing the breasts to bulge outwards. Usually, the same rope is used for both breasts so that the rope harness is automatically held together at the front. The rope may then also be fixed behind the back, to make a sort of brassiere. For this to work, the tied person needs fairly large breasts.
Another technique is to put a rope round the torso just above the breasts, and another one just below them, then push the ropes together to squeeze the breasts from the top and bottom, as shown at right. This can be done instead of, or as well as, the other method. A rope can also be passed over the shoulders and between the breasts, drawing the rope above and below the breasts together, then pass back over the shoulders to the knots at the back. The primary rope can be used to place cinches between the arms and the body.
This technique is often combined with elbow bondage, to make the breasts stick out even more, as shown in the picture above. When using elbow bondage in an advanced method, the elbow ropes as they pass under the shoulders and behind the neck can draw the ropes above and below the breasts together at the sides of the breasts, thus resulting in rope effectively surrounding the breasts. Alternatively, the ropes across the back can be linked to a box tie or a reverse prayer position.
Sometimes, nipple clamps are placed on the nipples.
Effect and other uses
Apart from the visual appearance of the breasts being lifted, the pressure that is applied results in a reduction in blood flow, and a further swelling and firming of the breasts. This makes them very sensitive, especially the nipples and surrounding areas, and it can be quite pleasurable to the bound person when they are stimulated. Conversely, if nipple clamps are used, the nipples will be particularly sensitive to this and the degree of pain significantly greater. Rubber bands around the breasts have also been used with breast bondage to increase this effect still further, but can lead to a dangerous restriction in blood flow (see safety).
Breast bondage can play an integral part in suspension bondage. If the subject is being suspended, particularly in a horizontal position such as a suspended hogtie, breast bondage is used as the main supporting area under the chest. If there are ropes above and below the breasts at the upper chest, the weight of the upper body is taken by these ropes. With so much pressure in this area, the rope must be precisely placed or once again blood flow could be reduced (see safety below). The Japanese use a sophisticated form of breast bondage called "shinju". Similar to breast bondage combined with a box tie, it is often used in suspension bondage.
As with any situation where tight ropes are used, it is possible that blood flow will be restricted too much, which can cause pain and lasting damage if care is not used. Photos of breast bondage sometimes show that the breasts have turned purple. If this happens, blood flow may have been restricted too long and it may be safer to remove or loosen the ropes.
