I was admitted to a general hospital due to poor health. Despite having an important detailed examination tomorrow, I was so hungry that I couldn't sleep even late at night. To distract myself, I decided to wander the night ward with a flashlight. As I walked down the pitch-black corridor, I heard a noise coming from the restroom. Peeking inside, I saw the head nurse, Ms. Okuda, with her legs wide open, pulling down her panties and masturbating. The next day, Ms. Okuda looked at me, smiled, and whispered in my ear, "You saw it, didn't you?" "The restroom at night is my own secret masturbation spot." A strict head nurse by day, a total slut by night. This veteran nurse, indulging in perverted masturbation in the hospital at midnight, greedily devours the cock of the young patient who peeked at her!!!
