Nipples and needles
Nipples are popular targets for needle play. This is where a hypodermic needle tip is thrust through the nipple or into/through the breast. Often there’s not a lot of pain associated with this, and even then it’s only as the needle is being inserted, but there is usually a strong psychological reaction such as fear or even fainting.
Although putting the needle in doesn’t cause much pain, once it’s in it can also be pulled on and twisted to cause pain. It’s important not to pull too much as this can cause the needle to tear out through the nipple.
The needles used are made of medical-grade stainless steel and because they’re metal it means they conduct electricity. This can affect electricity-based torture if done at the same time as piercing.
Below is a cross section of a woman’s breast showing the nipple, the milk ducts running to it, and the areola. Note that the ducts in the nipple itself are quite small and very vulnerable. As noted at the beginning of this article, the nipples are erogenous zones and also the source of milk for breastfeeding babies. Piercing and needle play involving the nipples, particularly when using larger diameter needles, risks nerve or milk duct damage.
An effective alternative to nipple piercing can be piercing the areola just above the nipple instead. The psychological effect can be the same and, of course, there’s little or no risk to the nipple itself. Indeed, rather than pierce the nipple with a single needle, some practitioners will pierce the areola all around the nipple with a number of needles instead.
