I believe you're talking about Mandy@GW, she's blessed with a perfect set of full-sized 36D breasts that show no obvious signs of sagging, her boobs' shape in almost tear drop shape. Sadly, she left the industry about six months ago. Lisa@Lavender aka Suki@Shangri-La, seems to come in a 34D size which would be akin to a 36C. Maybe because Lisa, aka Suki, has a smaller frame, about 5 feet height, her size seems quite big, but her bra size is just not on the same level as Mandy's. In the case of Tina, I really wouldn’t even describe her as busty.
Kiki@Shangri-la has a well-endowed size of 36D, however, there's noticeable sagging, maybe because Kiki is rather thin, she lacks the aesthetic appeal Mandy had.
The only one who could compare to Mandy would be Amber@Shangri-la, her round, large breasts - absolute works of art and great to behold, especially with the decorative and sexy big areolas. Even a quick glance at them keeps me longing over for about a week. Amber is truly a gem. Mandy, aka Ella at Shangri-la, once briefly worked at Shangri-la. After she left, the considerably younger, soft, and extra vibrant Amber quickly stepped in to fill her shoes.
