Hassun haven't you said you are a girl? Well shouldn't you have looked at other women's breast enough to realize those two women's breast are fake.
Miroku alot of times porn actresses will say in the porn video that their breast are real even though they look unnatural and you can see the surgery scars on their breast. So yeah they probably said they were real when actually they're not.
Also I added a link to my first post.
It is not just a silly generalization. On average Asian women have small breast. Even if someone stays in their room all day, lives in an area with no yellow people what so ever. There are enough women and teenage girls complaining on the interne that their C-cup makes them a freak in the eyes of their people.
