The first picture in post #3 is a definite bad photoshop job. Google search says that the second pic is Christy Hartburg - but that's incorrect. Hartburg starred in Russ Myer's film "Super Vixens" in 1975 and had massive fake boobs. This model looks more current and her breasts are the stuff of dreams. Likely photo-shopped but a good job.
In the GTA hobbying world I always thought that there were two MPA's who had perfect naturals - Sabrina/Angelina/Jayden of HFH, SRM, Allure then TGF, SexyFriends, Minx. She went the enhancement route - which turned out well, but her natural body was simply amazing. Trinity (ex-Allure) had perfect natural breasts too, IMO. The most memorable large, natural puffies I ever had the pleasure of seeing in this business was Sylvia who worked at Friends for too short a period. It might be my fuzzy memory - but her breasts were like the second model in Post #3.
