My beautiful niece was like that in high school. In her early 20s she had a reduction. Manny reasons including discomfort.
There was a girl like that in high school. She was literally unbelievable and all natural, as we watched her grow up. What made her so unbelievable is that the rest of her was so petite. She had a very nice personality too.
Guys would joke that she needed a counterweight hanging on her rear end to keep her from falling down face first.
