I don’t believe so. Maybe though. If it is true, then it’s just sucking the skin. Women, develop fat and muscle to form their breasts. And it’s also hormonal. Ever notice that females didn’t have breast until they started getting producing more estrogen?
You can work out and increase your bust size. Other than that, its hormones or surgery.
Oh also, you can go to my old job at Maidenform (Its a bra store) and they have silicone moldings that look like breasts that you insert into a bra. I know you’re hoping for a real pair of boobs, but other than the above things that you can do, you can try the inserts. They feel like real breast and I have had a lot of successful feedback from women who have bought them.
