>but for a girl that's like 140cm tall to have a 90cm chest is quite impressive
Is it really impressive when all it takes is someone that wants to market to waifufags to draw large circles on a girl's chest area?
Met a girl who had D's at 14 and G's at 16, she had to get reduction surgery
Such things are possible, just get them to play a lot of sports and be healthy when they're young and they'll develop if their genes let them
This got me sweating real hard.
