HOKS-019 Rin Hifumi: Kayo Kishimoto, 25, Fixates on Her Father-in-Law

Kayo Kishimoto, 25, works for a used office equipment company and has a boyfriend her own age. At home she secretly thinks about her quiet, moderately muscular father-in-law who lives with the family. In her free time she masturbates while imagining his strong cheeks, and the more she touches herself, the stronger the urge gets. One day her mother's return home is delayed by three hours, leaving Kayo alone with her father-in-law.
