>>189262 The tit meat comes from a multitude of things. Genetics and exercise, but age also plays a part. The skin is an organ. Healthy skin plays a part in beautiful boobs. Organs form, develop, grow, shrink, that is why you can exercise or treat different parts of your body, even injecting them with foreign chemicals for a desired reaction like women do with lip injections. Behind the fat there's muscle, but you can't do much about the boob fat itself. The fat texture is genetical so you work with what's behind and around the boob fat e.g. the skin and muscles. The skin is also genetical but of course there are a multitude of things you can use on your skin, and not all of it is natural. All boobs are different.
