Inverted nipples - thin needles penetration - small tiny holes

Girls and also men like two ways of making frontal holes into their nipples. Either using a thin tool - especially needle or syringe cannula or safety pin, etc. and penetrate their nipples mostly quite deep into their titflesh. This is kind of probing, what it is like, how painful it is and so on. And this is done mostly by young girls and beginners. However some mature ladies and grannies practice it too! After repeating it this leaves tiny and small holes in the middle of nipples. nThe other way is done mostly by older and more experienced - not pushing the tool so deep but using gradually thicker and thicker tools and enlarging the holes wider and wider, until after some time some of the nipples are completely inverted very deep after doing this regularly and frequently. This gallery is about penetrating nipples by thin tools, which leaves only tiny holes in them.
