 Nanri sakura 18 years old

She is a gifted and talented girl of discipline and sports.

She won the gold medal in the high school women's track and field competition, so she won the attention of the famous sports school.

Her excellent IQ and sports cells have made her a concern of the national fertility institution very early.

She was recruited by the National Institute of Reproduction and, with her own consent, was willing to provide genetics without restrictions.

She expanded her sex through surgery and added male sexual organs to the body to create excellent DNA sperm.

Because her life is low-key and does not want to receive too much attention, she gave up studying at a prestigious school and chose a general university to work and study.
