ROYD-331 - The beautiful senior who cancels going home! Being used as a sex toy by an overworked office lady

I got assigned to a new department, only to find out my desk is in the territory of 'Kinoshita', a gorgeous but overworked senior who never goes home. One night, I catch her masturbating at her desk. Once she realizes I'm watching, she decides to use me to satisfy her pent-up sexual desires.
