Inverted Nipples

Dorothy's dress had a zip behind it. I reached for the zip behind her dress and pulled it down. I then pulled her dress down exposing her black bra. I undid the strap of her bra and took it off. As I moved closer to her tits in order to suck her nipples, I saw something that I had never before seen in my life. Dorothy had inverted nipples. I fingered her on the couch for several minutes.
