Tawny Kitaen's breasts grow from big to gigantic in this nicely-done photomorph from R1A1N1D1I1. The funny thing is that in real life, Tawny Kitaen actually went through something similar.
Big tits? Not when she was younger! In one of her first movies, Bachelor Party, Kitaen played the slender, small-breasted, conservative girl who is humiliated to find her fiancee cavorting with a big-breasted hooker. (The first scene of the movie features the spectacularly busty Angela Aames, looking absolutely amazing.)
Nature was kind to Tawny, though, because ten years later it was Kitaen who regularly played the big-breasted lust object herself, in any number of TV shows and movies. And she filled out those roles admirably.
