Black and Nipple Orgams

I can cum from nipple play. I don't need to even touch my throbbing clit, I just squeeze my nipples back and forth until I'm creaming and cumming. My breast are big (36DD) and my nipples are a cinnamon color with shiny barbell through each one and are soft and sensitive. Sometimes when I suck on them and clench my legs tight I cum within seconds and the feeling is so intense I can do it forever, having orgasms non-stop. Can anyone else relate?
