【The Power Behind the Scenes】Urai Serina from the General Affairs Department has always prioritized others over herself. Now, her erotic duties are unsealed. She's the kind of person that employees tend to talk to even when they have no business with her, exuding a sense of reliability and security. Once she takes off her clothes, you'll see 『her firm yet soft self-proclaimed F-cup beautiful breasts』… Please enjoy the first time of Usui, feeling bewildered yet aroused by SOD's traditional multi-ero task.
