28-year-old strict sales dept. boss Rinna Yomikawa was a cool beauty, but she had a secret too shameful to admit: She had hot f*ck fantasies all day long, but she was also a virgin! A series of events led you to learn this secret. As the only person with knowledge of Rinna's filthy hidden side, you were naturally the only partner for helping her explore her sexuality!
