Wakana Shiroyama is a bank employee. Her daily life at the bank is a series of ridiculous words such as "I currently work at the bank without underwear" and "Before that, I worked with a remote vibrator inserted." When I asked her, I found out that she has a master, and if she makes any mistakes, she will be punished, so she is a sex slave who faithfully follows his orders. The lewd daily life of a masochistic bank employee who decided to appear in an adult video at the command of her master.
