48-year-old married woman and public servant from Saitama, Shinobu. Tall with a 92cm bust. Twelve years ago, she married her workplace lover, and now they work at separate locations. No children. Her marriage began through a coworker relationship. Her husband is ten years older. Initially deeply in love, their relationship gradually became sexless. Six months ago, she started a casual affair with someone she met through a dating site. When it was exposed, the man—also married—threatened to inform her husband unless she paid him money. This blackmail led her to apply, seeking compensation for the affair.
