When I was assisting in the start up of bignipple.com a few years back, one of my jobs was finding content. I was in Vegas on the floor asking content providers if they had any sets of girls with big or puffy nipples. The one guy actually said to me "All our models have nipples"
John - you might be better off building a "nice nipples" site - include puffy, big, dark, etc.
