Im a fairly thin person, but I don't make myself this way, it's just the way I'm built, but I'm not so thin that you can see my ribs that is just too thin lol.
I have tried to put on weight but can't do it. As for beasts I really want mine bigger even tho I suposse the size they are and right for my body size, but still bigger boobs would be nice, but I don't wanna do surgery
