it depends dude. The chick with the big ol' breasteses is MidWest Mandy, very very very very easy to find just about anywhere (askjolene.com for example) I don't know who the other, smaller chick is, and unless I am mistaken, you probably don't care. If it is she who you seek, then i cannot help you. Good luck.
her name is Kim, and is on mandy's site and others.
