I was admitted to the hospital where my girlfriend's best friend works for a 3-day medical checkup. During the physical exam, I got really close to the nurse! I got an erection without realizing it, and instead of getting angry, she was really interested in my dick. When everyone was asleep, we were alone in the hospital room in the middle of the night! We had sex in the hospital without my girlfriend knowing! Even though I knew it was wrong, I was so engrossed in my sexual desire that I couldn't turn back. This is the record of 3 days filled with that.
