"Dad, I'm sorry..." Yuko Shiratori, 20 years old, female college student. I appeared in an adult video the other day... I wanted to save money, but I was also a bit interested... This was the only time. I may have been a bit out of control. ...I'm a bit remorseful. This will really be the last time, so please forgive me. A well-bred, ladylike female college student showed up at the usual Shibuya meeting place. Her orthodontic teeth when she smiles are cute, a vestige of her teenage years.
