When she became a junior high school student, she was very worried because her breasts were not getting bigger. Looking around, her friends were getting bigger and bigger. Some of them were F cups. But she was an A cup like a chopping board. Why was it only me? She was depressed. Even when she went to buy underwear, was it necessary to wear a bra on such a small chest? Such questions ran through her head. She was embarrassed to wear clothes that exposed her chest. When her friends invited her to the beach or hot springs, she really cried. In the end, she stayed home instead of going. For her, her small breasts had become a big complex. "My breasts just haven't grown yet. Soon they will be bigger than anyone else's." That's what she had been thinking and telling herself until now. But recently she had been feeling anxious. She was about to become a high school student. But there was still no sign of her breasts getting bigger. Maybe she would stay an A cup forever. It suddenly started to seem that way. So she decided to stop staying up late. After doing some research on her own, she found that there seems to be a strong correlation between breast size and sleep time. It is especially important to sleep between 10pm and 2am, when growth hormones are secreted. So she decided to give up on her favorite late-night anime and go to bed early. She also learned that in order to increase her bust size, it is important to be aware of female hormones. Excessive stress, intense exercise, dieting through drastic food restrictions, lack of sleep, and lack of nutrition are major causes of imbalance and reduction of female hormones. So she moderated her studies and tried not to accumulate too much stress. And then, what happened? Her breasts started to grow bigger and bigger, as if it were a lie. By the time she entered university, they had grown to a D cup. She regained confidence in her body. I want you to see more of my big breasts. That's why she decided to appear in this video. Please enjoy her breasts that look so comfortable.
