I had the research done for Missy's bio a couple of times but each time I pull back and end up doing someone more naturally top heavy. However, the requests for Missy just keep coming in so I'm going to break down and do this biography.
I believe Missy is from Russia and started in the adult industry in mid-2008.
She is a natural B cup but many of her pictures and videos were done in the first months of her pregnancy in 2008 and her boobs had ballooned up to a D or DD. They also got these really puffy nipples that look fantastic. You can see pictures of Missy where she isn't pregnant and is a B cup
here.
The following galleries are from when she was pregnant and at her larger D-cup size.
