The following ladies have, in my opinion, great tits:
Julia Ann
Tanya Danielle
Devon Michaels
Lana Lotts
Jasmine Aloha
Alley Baggett
Tylene Buck
Francine Dee
Lorissa McComas
Shae Marks
Jennifer Walcott
April Arikssen
Pamela Anderson
Traci Bingham
Nina Mercedez
First person that came to mind was Gianna Michaels because her breasts (which are DD's I think) are huge enough for any "boob guy" to love but natural enough to enjoy. I mean they look so soft and of course, are perfect for tit fucking, which in my opinion would almost be better then intercourse with her.
