Koharu Shiina is a 21-year-old from Hokkaido who worked at the front desk of a hotel. She is a talented girl with a handsome face and a 9-inch head and an E-cup body, and she decided to make her debut, saying, ``I want to take on the last challenge of her life.'' She's so bold and lewd when it comes to sex that you can't even imagine from her intimate and elegant appearance! Looks, eroticism, spirit, all aspects of beauty! I want to seriously fall in love and have sex with a girl like this.
