Yang Lan, 30 years old, is a senior teacher in a key middle school. She is 167 in height. Although her appearance is not impressive, she can also be called a beautiful woman. It is said that women go downhill after 30, but this is a typical exception for Yang Lan. Yang Lan not only has fair skin, but also keeps a good figure. Although she can no longer compare with young girls, her breasts are still so straight and plump. Her waist is basically free of excess flesh. Her two long and round legs are still tight and straight, especially the big butt behind her is round and fat.
