Sayaka is a virgin who graduated from an industrial school and works as a mechanic. Because she has lived in a man's society, she sees men as companions rather than members of the opposite sex, so she remained a virgin until she was 20 years old. She is interested in both love and sex, so she takes the plunge and applies for AV. She has a boyish appearance, but when she takes off her uniform, her big E-cup breasts are exposed! She felt a little pain during her penetration, but once she learned how to cum with her first toy, she started to realize how good sex felt.
