I was admitted to the hospital where my girlfriend's best friend, Satomi, works for a three-day medical checkup. During the physical examination, I got very close to the nurse, Satomi! I got an erection without thinking, and instead of getting angry, she was very interested in my dick. When everyone was asleep, I was alone with Satomi in the hospital room in the middle of the night! We had sex in the hospital without my girlfriend knowing! I got immersed in our naughty relationship that lasted only three days...
