Femanons, the penalty for having boobs smaller than this is that you must post them. It's a new law.
I think she is just pushing them together with the arm holding the phone. My wife has a similar, albeit slightly smaller, rack, and I've seen her look like this any number of times.
Dont wanna break any fucking laws
Kek how old are you? Breast are usually the size they're going to be for life at 15. Sure they might grow some, but very slightly.
Only way to gain breast size after that is, children (but they will sag after breastfeeding), surgery, or gaining weight.
