Not all girls can control how big their boobs are unless you are referring to those who get implants, but even then, it's their body their choice
my boobs are oversized imo
Indeed women can't control what their boob size is. Also yeah talking about implants and yes it's their choice.
But god damn. No need to get them that big. If a woman gets these or thinking about getting them that size, she serious needs to think about herself and see how beautiful she is and be glad of what she had or has.
